Description

The invention relates to a collecting container for workpiece particles, which is intended for coupling to a motor-driven hand tool. The collecting container comprises a container body, which is delimited by an outer skin, and a connecting piece for coupling the container body to the hand tool. The connecting piece has a free end that protrudes from the container body.

The invention is further directed to an assembly comprising a motor-driven hand tool and such a collecting container.

Furthermore, the invention is directed to a motor-driven hand tool for use in such an assembly.

Such collection containers, assemblies and motor-driven hand tools are known from the prior art. In this context, the outer skin of the container body is usually made of a material that is permeable to air but retains workpiece particles above a predetermined particle size. In other words, the outer skin works as a filter to separate workpiece particles from air. An air-workpiece particle mixture resulting from material processing carried out using the associated hand tool can thus be introduced into the collection container via the connection piece. The workpiece particles are retained in the collection container so that the material processing causes comparatively little contamination.

Known collection containers are generally compatible with at least various motor-driven hand tools from the same manufacturer. If various motor-driven hand tools are required for material processing, the same collection container can be used. However, it must be uncoupled from one hand tool when partially full and coupled to another hand tool. The collection container is also often uncoupled from the associated hand tool and coupled to it again to empty it.

In this context, it is known to equip the collecting container with a locking mechanism that is spring-loaded into a closed position. Such locking mechanisms can be designed in such a way that they are moved from the closed position to an open position against the spring load by coupling the collecting container to an associated hand tool. If the collecting container is uncoupled from the hand tool, the locking mechanism automatically returns to the closed position due to the spring load. However, collecting containers with such locking mechanisms have the disadvantage that when uncoupled, a certain residual amount of workpiece particles always remains in an area of the connection piece that is outside the locking mechanism. This residual amount of workpiece particles can escape into the environment in an uncontrolled manner when the uncoupled collecting container moves.

The aim of the present invention is to eliminate or at least mitigate this disadvantage. At the same time, coupling the collecting container to a hand tool and uncoupling it from it should remain simple.

The problem is solved by a collecting container for workpiece particles, which is designed to be coupled to a motor-driven hand tool. The collecting container comprises a container body, which is delimited by an outer skin, and a connecting piece for coupling the container body to the hand tool. The connecting piece has a free end that protrudes from the container body. The collecting container also comprises a connecting piece cover, which is rotatably mounted on the connecting piece and can optionally close and release the connecting piece at the free end. The connecting piece cover therefore closes the connecting piece at the end that protrudes from the container body. Consequently, when the connecting piece cover is closed, at least those sections of the connecting piece through which an air-workpiece particle mixture flows when the collecting container is in operation are on the same side of the connecting piece cover as the container body. In other words, when the nozzle cover is closed, those sections of the connection nozzle through which a mixture of air and workpiece particles flows during operation of the collecting container are separated from the surroundings of the collecting container by means of the nozzle cover. No workpiece particles can escape from this section of the connection nozzle. Undesirable contamination can therefore be excluded. When the nozzle cover releases the connection nozzle, the connection nozzle can also be described as open. The rotatable bearing on the connection nozzle makes it easy to move the nozzle cover from an open state to a closed state and vice versa. It is understood that the rotatable bearing of the nozzle cover on the connection nozzle only allows a rotary movement of the nozzle cover against above the connecting piece. All other degrees of freedom of movement are blocked by the bearing. A further advantage of the connecting piece cover of the collecting container according to the invention is that, when opened, it lies outside the sections of the connecting piece through which an air-workpiece particle mixture flows when the collecting container is in operation. In other words, such a flow is not hindered or restricted by the connecting piece cover.

The collecting container can also comprise a securing element by means of which the nozzle cover can be secured in a position in which it closes the connection nozzle at the free end. The securing element can optionally assume a securing position in which it secures the nozzle cover in the position in which the nozzle cover closes the connection nozzle. In addition, the securing element can optionally assume a release position in which it releases the nozzle cover so that it can be transferred from the position in which it closes the connection nozzle to another position, in particular the position in which it releases the connection nozzle. The securing element can comprise a linearly movable component or a rotationally movable component. The movable component is optionally spring-loaded or otherwise pre-tensioned. The safety element comprises, for example, a safety hook, a safety lever, a safety clip, a safety pin or another suitable means for securing the nozzle cover in the position in which it closes the connection nozzle at the free end. Using a safety element is a particularly reliable way of preventing workpiece particles from escaping from the collecting container in an undesirable manner.

Preferably, the safety element can be operated manually.

Depending on the specific application, the workpiece particles are also referred to as dust, e.g. grinding dust, or chips, e.g. sawdust.

The nozzle cover can be rotatable about an axis of rotation that runs transversely to a longitudinal extension direction of the connecting nozzle. In other words, the axis of rotation runs parallel to a tangential direction on an outer circumference of the connecting nozzle. A nozzle cover mounted in this way can, on the one hand, be easily transferred from the open state to the closed state and vice versa. On the other hand, the nozzle cover can reliably close the free end of the connecting nozzle in the closed state.

According to one variant, the nozzle cover is mounted on the connecting nozzle via a bearing block. The bearing block is positioned on an outer circumference of the connecting nozzle. From a mechanical point of view, the nozzle cover is thus stably and reliably mounted. It can therefore be transferred from the open state to the closed state and vice versa with high reliability. Furthermore, this type of bearing has a long service life.

In one embodiment, the nozzle cover is pre-tensioned into a closed position by means of a spring device, in which the nozzle cover closes the connection nozzle at the free end. The nozzle cover thus assumes the closed state when no forces other than the pre-tensioning force act on it and the assumption of the closed state is not blocked in any other way. This prevents workpiece particles from escaping from the collecting container in an undesirable manner.

The spring device comprises, for example, a leg spring made of metal.

The nozzle cover can comprise a closure section and an actuating section set apart from it, the actuating section being designed to manually release the free end of the connecting nozzle. The closure section and the actuating section are therefore separate sections of the nozzle cover. The closure section and the actuating section can be formed integrally on the same component. Alternatively, the closure section and the actuating section are implemented by two separate components that are coupled to one another. In both alternatives, the nozzle cover can be actuated particularly easily due to the actuating section. In addition, the free end of the connecting nozzle can be reliably closed due to the closure section.

Preferably, the closure section and the actuation section form an obtuse angle in a plane of rotation. The included angle is the smallest angle that the closure section and the actuation section form when viewed along the axis of rotation. The actuation section is therefore always easily accessible. Furthermore, an associated actuation force can be easily applied.

The actuating section and the locking section can be positioned on opposite sides of the rotation axis. This also ensures good accessibility of the actuating section. Furthermore, the actuating section in this Variant has an operating lever, by means of which the locking section can be operated with comparatively low forces due to the leverage effect.

According to one embodiment, the axis of rotation is spaced from the outer circumference of the connecting piece, so that the actuating section can be moved, in a view along the axis of rotation, to a side of the axis of rotation facing the connecting piece. The actuating section can therefore be moved closer to the connecting piece, at least in sections, than the axis of rotation is away from the outer circumference of the connecting piece. This allows the closure section to be brought into a position in which, when viewed perpendicular to a cross section of the free end of the connecting piece, it lies outside the cross section. In particular, in this position and when viewed in this way, the closure section has a distance greater than zero from an outer circumference of the cross section of the connecting piece. Put simply, the nozzle cover can be opened very wide. This ensures that the nozzle cover does not hinder coupling the collecting container to an associated hand tool or decoupling the collecting container from the associated hand tool. In other words, there is a large amount of free space for coupling and decoupling.

The connection piece can have a sealing section on the connection piece side on its inner circumference, adjacent to the free end. This allows the collection container to be reliably coupled to an associated hand tool. Any undesired escape of workpiece particles in the area of the coupling is effectively prevented.

The nozzle cover can also have a sealing section on the cover side, which is designed to be at least partially opposite the connection nozzle side sealing section or to rest against the connection nozzle side sealing section in the closed position. As a result, the collecting container can be reliably closed. An undesired escape of workpiece particles is effectively prevented.

Preferably, at least one of the cover-side sealing section and the connection piece-side sealing section has a sealing element. The already mentioned high reliability of the seal is thereby further increased. An undesirable escape of workpiece particles is thus particularly avoided.

According to an alternative, a retaining rib is provided on the nozzle cover for locking the collecting container in a position coupled to the motor-driven hand tool. The collecting container can thus be reliably coupled to the hand tool using the nozzle cover. The nozzle cover therefore has two functions. On the one hand, it serves to close the collecting container in a situation in which it is uncoupled from a hand tool. On the other hand, it serves to securely and reliably lock the collecting container to the hand tool when the latter is coupled to the hand tool.

The retaining rib can be arranged on the closure section. This allows the collection container to be reliably locked onto the hand tool.

In one variant, the retaining rib is positioned on a side of the closure section facing the connecting piece. This means that in a state in which the connecting piece is closed by means of the piece cover, the retaining rib is located inside the connecting piece. In other words, the retaining rib does not interfere with the handling of the closed collecting container. On the other hand, with such a positioning of the retaining rib, a simple and reliable locking of the collecting container to the hand tool is possible.

The retaining rib can have a mounting bevel. This makes it easier to achieve a state in which the collecting container is locked to the hand tool by means of the nozzle cover. By the mounting bevel coming into contact with an element on the hand tool that is intended to interact with the retaining rib, the retaining rib can be adjusted to a position that is necessary for locking the collecting container to the hand tool.

According to one embodiment, a recess is provided on the nozzle cover for receiving a section of the hand tool in a position of the collecting container coupled to the motor-driven hand tool. This allows the collecting container to be coupled to the hand tool particularly reliably. Furthermore, this makes it possible for the nozzle cover to assume a position that is close to an outer contour of the hand tool in a state in which the collecting container is coupled to the hand tool. This makes it easier to handle the assembly consisting of the collecting container and the hand tool.

The recess can be arranged on the closure section. This results in a space-saving and reliable coupling of the collection container to the hand tool.

In one variant, the recess is positioned on a side of the closure section facing the connection piece. This means that in a state in which the connection piece is closed by means of the piece cover, the recess is located inside the connection piece. In other words, the recess does not interfere with handling the closed collecting container. On the other hand, positioning the recess in this way enables the collecting container to be coupled to the hand tool in a simple and reliable manner.

The retaining rib can be closer to a rotation axis of the nozzle cover than the recess. This means that the collecting container can be reliably coupled to the hand tool and locked in this state. This type of configuration also saves space.

Preferably, in a release position in which it releases the connection nozzle at the free end, the nozzle cover forms an angle of greater than 90° with a connection cross-section of the connection nozzle. This angle is preferably measured around the axis of rotation of the nozzle cover. Put simply, the nozzle cover can be opened very wide. This ensures that the nozzle cover does not hinder coupling the collecting container with an associated hand tool or decoupling the collecting container from the associated hand tool. In other words, there is a large amount of space available for coupling and decoupling.

The same effect is also achieved if the axis of rotation of the nozzle cover is at a comparatively large distance from an outer circumference of the connecting nozzle. In such a configuration, the nozzle cover can enclose an angle of greater than 90° with the connection cross-section of the connecting nozzle in the release position. Alternatively, it is also conceivable that the angle is 90° or less than 90°.

The connection piece can be provided on a dimensionally stable section of the outer skin. Due to the dimensionally stable section, the collecting container has a fixed geometry in the area of the connection piece. This makes it easier to connect and disconnect the collecting container to or from the hand tool.

The dimensionally stable section and the connecting piece can be manufactured as one piece. This is efficient in terms of manufacturing technology. Assembly operations to connect the dimensionally stable section to the connecting piece are not necessary.

In one variant, the outer skin has a light incidence section that is translucent. The outer skin also has a viewing window section that is transparent. At least one point of the light incidence section is connected to at least one point of the viewing window section by a straight line of sight. A user of the collecting container and a hand tool coupled to it can thus determine a current fill level by looking into the interior of the collecting container through the viewing window section. Light can fall into the interior of the collecting container through the light incidence section. Consequently, that area of the interior of the collecting container is illuminated by light that falls through the light incidence section. A current fill level of the collecting container can thus be determined with high precision and reliability. At the same time, all other sections of the outer skin, i.e. all sections except the light incidence section and the viewing window section, are permeable to air and can perform the desired filter function for separating workpiece particles above a predetermined particle size and air. Optionally, the light incidence section is also permeable to air and acts as a filter. It is emphasized that the light incidence section is a section of the outer skin and therefore always includes outer skin material. In other words, the light incidence section is not designed as an opening. The filter effect is therefore only slightly influenced by the viewing window section and, if applicable, the light incidence section.

In one variant, an emptying opening for removing workpiece particles from the container body is arranged in the outer skin and an emptying direction associated with the emptying opening extends from the interior of the container body through the emptying opening. The emptying direction is essentially perpendicular to an opening cross-section of the emptying opening. Furthermore, a closure means is provided which can be fastened to the container body at least in a closed position, so that the emptying opening can be optionally closed by means of the closure means. In a use position of the collecting container, when the closure means is in an open position, the emptying direction has an extension component pointing vertically in the direction of a processing zone. In the closed position of the closure means, the emptying opening is closed by means of the closure means. In the open position, the emptying opening is released. In the open position, the closure means can be connected to the container body or separated from the container body. A usage position of the collecting container corresponds to the position that the collecting container assumes when it is coupled with an associated hand tool and the hand tool is in a normal position or reference position. limit position. In this case, a processing zone lies along a vertical direction below the hand tool with which the processing is carried out. The processing zone is therefore also located vertically below the collecting container. Information on the processing zone and the usage position refer to this case. It goes without saying that with some hand tools, which can also be equipped with collecting containers, work can also be carried out vertically or overhead. However, such working positions are regarded as an exception in the present case and are not used as a reference. In the usage position, a central axis of the connecting piece usually has a horizontal extension component. Preferably, the horizontal extension component is larger than a vertical extension component of the central axis of the connecting piece. More preferably, the horizontal extension component of the central axis of the connecting piece is at least twice as large as the vertical extension component. In the usage position of the collecting container, the emptying direction therefore has an extension component that points vertically downwards. Workpiece particles present inside the collection container can thus leave the interior of the collection container through the emptying opening using gravity. The collection container can remain coupled to the associated hand tool, whereby the hand tool can assume the normal position. In other words, the hand tool with the coupled collection container does not have to be placed in an ergonomically uncomfortable position. This makes it particularly easy to empty the collection container. The fact that the emptying direction has an extension component vertically downwards also means that the workpiece particles can be emptied in a targeted manner into a container that is positioned below the collection container. Undesirable contamination by workpiece particles is thus avoided.

The dimensionally stable section can be designed as a closure means for selectively opening and closing the emptying opening in the outer skin of the container body. The collecting container can thus be selectively opened for emptying using the closure means.

According to one embodiment, the container body comprises a folding mechanism so that the container body can optionally assume a working position in which the outer skin encloses a first volume, and optionally assume a transport position in which the outer skin encloses a second volume. The second volume is smaller than the first volume. In the working position, a first outer skin length dimension has a greatest length compared to the other outer skin length dimensions. In the transport position, the first outer skin length dimension defines a greatest length of the container body. In this context, an outer skin length dimension is to be understood as a length dimension of the outer skin. The orientation of the length dimension in space is not important. Depending on the spatial orientation of the container body, an outer skin length dimension can therefore be a length, a width or a height. Furthermore, an outer skin length dimension can be defined between any pairs of surfaces, edges and corners of the outer skin. Dimensions of surfaces and edges of the outer skin also fall under the term outer skin length dimension. For example, an outer skin dimension extends along an edge of the outer skin. The collection container according to the invention is therefore characterized in that a greatest length of the container body in the transport position is defined by the outer skin length dimension in the working position that has the greatest length in the working position. In other words, the container body can be folded up using the folding mechanism in such a way that the greatest outer skin length dimension in the working position, which does not necessarily have to be the largest overall dimension of the container body, becomes the largest overall dimension of the container body in the transport position. The container body therefore does not become any longer by folding it up. In this way, a good compromise can be achieved between the largest possible volume of the container body in the working position and the smallest possible volume of the container body in the transport position. Ideally, the volume is zero in the transport position.

The task is also solved by an assembly that includes a motor-driven hand tool and a collecting container according to the invention. The collecting container is fluidically coupled to the hand tool via the connecting piece, so that an air-workpiece particle mixture can be introduced into the collecting container from the hand tool. The nozzle cover of the collecting container according to the invention is in an open state. It lies outside the sections of the connecting piece through which an air-workpiece particle mixture flows when the collecting container is in operation. In other words, such a flow is not hindered or restricted by the nozzle cover. The rotatable mounting on the connecting piece also makes it easy to transfer the nozzle cover from an open state to the closed state when the collecting container is decoupled from the hand tool. and vice versa, if the collection container is to be coupled to the hand tool.

The nozzle cover of the collecting container can at least partially contact a contact area of the hand tool. The nozzle cover thus takes up a defined position.

Alternatively or additionally, the nozzle cover can engage behind a retaining bead on the hand tool so that the collecting container is locked to the hand tool. The coupling between the collecting container and the hand tool is therefore particularly safe and reliable. In particular, the retaining rib on the nozzle cover engages behind the retaining bead on the hand tool.

The retaining bead can have a mounting bevel. This makes it easier to achieve a state in which the collecting container is locked to the hand tool by means of the nozzle cover. By the mounting bevel on the retaining bead coming into contact with an element of the nozzle cover that is intended to interact with the retaining bead, the nozzle cover can be adjusted to a position that is necessary for locking the collecting container to the hand tool.

The object is also achieved by a motor-driven hand tool for use in an assembly according to the invention. The motor-driven hand tool comprises an outlet for discharging an air-workpiece particle mixture, wherein a retaining bead for coupling a collecting container for workpiece particles is arranged on an outer circumference of the outlet. This collecting container is in particular the collecting container according to the invention. By means of the retaining bead, the collecting container can be coupled to the hand tool with particularly high reliability and locked there.

Furthermore, the effects and advantages already explained in connection with the collecting container according to the invention and the assembly according to the invention also apply to the hand tool according to the invention and vice versa.

1 shows a hand tool system 10.

The hand tool system 10 includes a storage container 12 and an assembly 14 having a motor-driven hand tool 16 and a collecting container 18 for workpiece particles.

In the present example, the motor-driven hand tool 16 is a hand-held circular saw. However, this is to be understood purely as an example.

The collecting container 18 is fluidically coupled to the hand tool 16 so that when working with the hand tool 16, an air-workpiece particle mixture can be introduced from the hand tool 16 into the collecting container 18.

For this purpose, the collecting container 18 has a connecting piece 20, which forms an inlet opening 21, and a flexible container body 22 in which a certain amount of workpiece particles can be received.

The connecting piece 20 is designed to be coupled to the hand tool 16 at its free end 24. At its opposite end, the connecting piece 20 opens into the container body 22.

The container body 22 comprises a support structure 26, which is constructed from several rigid struts 28, which are connected to one another via joints 30. The struts 28 and joints 30 form a folding mechanism 31, which will be explained below.

Furthermore, the container body 22 comprises an outer skin 32, which is formed as a covering 34 enclosing the support structure 26. It is noted that in the illustrations from the 1 , 2 , 5 and 6 For reasons of better visibility of the supporting structure 26, the outer skin 32 is not shown.

The container body 22 takes in the 1 and 2 a transport position.

Furthermore, in the presentation according to 1 The assembly 14 is arranged inside the storage container 12. A lid of the storage container 12 is not shown. It is noted that in particular in the illustration according to 1 , ie in a situation in which the assembly is arranged within the storage container 12, the collecting container 18 is fluidically coupled to the hand tool 16. This is made possible by the compactness of the transport position.

In this case, a main extension 36 of the container body 22, i.e. the direction of the relatively largest length dimension of the container body 22, runs transversely to a main flow direction 38. In this context, the main flow direction 38 runs from an outer skin surface supporting the connection piece 20 in the direction of an outer skin surface opposite in this respect. It is understood that the main flow direction 38 is defined independently of whether or not an air-workpiece particle mixture actually flows from the hand tool 16 into the collecting container 18.

In addition, a height 42 of the container body 22 in the transport position is at most as large as a height 46 of the hand tool 16 defined vertically on a support plate 44 of the hand tool 16. In other words, a height 42 of the container body 22 in the transport position does not exceed the height 46 of the hand tool 16.

In addition, a length 48 of the container body 22 along a longitudinal direction 50 of the hand tool 16 is at most 50% of a length 52 of the support plate 44 when the container body 22 is in the transport position. In the example shown, the length 48 of the container body 22 is approximately 20% of the length 52 of the support plate 44.

Furthermore, a width overhang 54 of the container body 22 over a width 56 of the support plate 44 in the transport position amounts to approximately 40% of the width 56 of the support plate 44.

In the 3 to 6 The collecting container 18 according to the first embodiment is shown in more detail. The 4 and 6 show the transport position of the container body 22. The 3 and 5 show a working position of the container body 22, which will be explained below.

In the embodiment shown, the support structure 26 is polygonal in a lateral view with respect to the main flow direction 34. In this context, the joints 30 form the polygon corners of the polygon shape and the struts 28 form the polygon edges.

The polygon has five polygon corners.

In the transport position, a polygon corner, i.e. a joint 30, is accommodated between two polygon edges, i.e. between two struts 28, forming a concave outer peripheral section.

As a result, in the transport position, an outer skin section, i.e. a section of the outer skin 32, is folded into an interior of the container body 22.

By means of the folding mechanism 31, the container body 22 can be transferred into the working position, which is in the 3 and 5 is shown. In the working position, the container body 22 extends along the main flow direction 38. This means that a largest external dimension of the container body 22 is oriented in the same direction as the main flow direction 38.

In the working position, the outer skin 32 encloses a first volume V1 that is much larger than a second volume V2 that encloses the outer skin 32 in the transport position. Thus, in the working position, a comparatively large amount of workpiece particles can be accommodated in the interior of the container body 22.

In the working position, the collecting container 18 has at least a first outer skin length dimension Lmax, which has a greatest length compared to the other outer skin length dimensions of the collecting container 18.

In the embodiment shown, the first outer skin length dimension Lmax is formed by a region of the outer skin 32 which rests on one of the struts 28.

The first outer skin length dimension Lmax therefore corresponds to the length of the longest strut 28 of the collecting container 18.

The fact that in the working position the first volume V1 enclosed by the outer skin 32 is much larger than the second volume V2 enclosed in the transport position, while at the same time the container body 22 is extremely compact in the transport position, is due to the fact that the first outer skin length dimension Lmax defines a maximum length of the container body in the transport position. In other words, the first outer skin length dimension Lmax in the transport position determines the maximum external dimension of the container body 22.

It is understood that the container body 22 can also be transferred from the working position back into the transport position by means of the folding mechanism 31. In other words, the container body 22 can optionally assume the transport position or the working position by using the folding mechanism 31.

In addition, the outer skin 32 comprises at least one elastically deformable outer skin section 58.

The folding mechanism 31 is configured such that the elastically deformable outer skin section 58 is maximally elastically stretched in an intermediate position which the container body 22 assumes when it is transferred from the transport position to the working position and vice versa.

This means that the container body 22 can be held mechanically stable in the working position and in the transport position by means of the elastically deformable outer skin section 58. The intermediate position is mechanically unstable.

The 7 , 8 and 9 show the assembly 14, wherein the collecting container 18 is designed according to a second embodiment. In the following, only the differences from the first embodiment are explained. Identical or corresponding components are provided with the same reference numerals.

As before, the support structure 26 is polygonal in a lateral view with respect to the main flow direction 34, wherein the joints 30 again form the polygon corners of the polygon shape and the struts 28 again form the polygon edges.

However, the polygon in this case has only four polygon corners.

A further difference is that the main extension 36 of the container body 22 in the transport position (see 9 ) no longer runs transversely, but at an angle of approximately 30 degrees to the main flow direction 38.

This results in the situation that the container body 22 in the transport position has no width overhang beyond the width 56 of the support plate 44.

The length 48 of the container body 22 along the longitudinal direction 50 of the hand tool 16 is now approximately 70% of a length 52 of the support plate 44 when the container body 22 is in the transport position.

Furthermore, reference can be made to the explanations regarding the collecting container 18 according to the first embodiment.

The 10 and 11 show the assembly 14, wherein the collecting container 18 is designed according to a third embodiment. In the following, only the differences from the already mentioned embodiments are explained. Identical or corresponding components are provided with the same reference numerals.

In this embodiment, the struts 28 and the joints 30 form a cross rod 60. In the working position (see 10 ), the middle areas of the struts, which are assigned to each other in pairs, overlap in a cross-like manner.

In the transport position (see 11 ), the struts assigned to each other in pairs are essentially placed on top of each other.

In this context, the first outer skin length dimension Lmax is formed by a region of the outer skin 32 which rests on one of the cross-shaped struts 28.

In other words, the first outer skin length dimension Lmax again corresponds to the length of the longest strut 28.

In contrast to the aforementioned embodiments, in the third embodiment the outer skin as a whole is elastically deformable.

The width overhang in the transport position of the container body now amounts to approx. 15%.

The length 48 of the container body 22 along the longitudinal direction 50 of the hand tool 16 is now approximately 40% of a length 52 of the support plate 44 when the container body 22 is in the transport position.

The 12 and 13 show the assembly 14, wherein the collecting container 18 is designed according to a fourth embodiment. In the following, only the differences from the already mentioned embodiments are explained. Identical or corresponding components are provided with the same reference numerals.

In this embodiment, the struts 28 are each C-shaped.

They each have a joint 30 at the ends of the C-shape, via which the struts 28 are connected to one another in an articulated manner.

In the embodiment shown, all joints 30 have the same joint axis. The struts 28 can thus be rotated in a fan-like manner towards each other and can thus be switched between the working position in which the struts 28 are fanned out (see 12 ), and the transport position in which the struts 28 are placed on top of each other (see 13 ), adjust.

In this context, the first outer skin length dimension Lmax is formed by an arch height of the C-shaped struts 28.

In contrast to the aforementioned embodiments, in the fourth embodiment the outer skin 32 can be designed without an elastic section. The outer skin is therefore not elastically deformable overall.

The width overhang in the transport position of the container body now amounts to approx. 15%.

The length 48 of the container body 22 along the longitudinal direction 50 of the hand tool 16 is now approximately 40% of a length 52 of the support plate 44 when the container body 22 is in the transport position.

The 14 and 15 show a fifth embodiment of the collecting container 18. The collecting container 18 according to the fifth embodiment is a variant of the collecting container 18 according to the second embodiment (see 7 to 9 ). Therefore, only the differences to the second embodiment are explained below. Identical or corresponding components are given the same reference numerals.

In the collecting container 18 according to the fifth embodiment, the outer skin 32 has a serrated section 62 in the working position. This serves to enlarge an area of the outer skin 32, while at the same time the outer dimensions of the container body 22 can be kept the same compared to a collecting container 18 with an outer skin 32 without a serrated section. This can improve the filter function of the outer skin 32.

The serrated section 62 is formed by two of the struts 28 of the support structure 26 being serrated (see 15 ). The serrated struts 28 are additionally provided with the reference symbol 64a or with the reference symbol 64b.

The teeth of the serrated struts 64a, 64b are arranged such that, when viewed along the main flow direction 38, a circumference of the container body 22 along the main flow direction 38 remains constant in magnitude.

This is achieved by the arrangement of the teeth of the serrated struts 64a, 64b. For a better understanding, 15 For the serrated strut 64a, an imaginary zero line N1 of the serrations is drawn. For the serrated strut 64b, an imaginary zero line N2 is drawn.

The zero lines N1, N2 correspond to the course of a straight, i.e. non-serrated strut, which could be used instead of the serrated struts 64a, 64b.

In addition, several exemplary volumes 66a, 66b, 66c are in 15 illustrated.

The points of the struts 64a, 64b, i.e. the associated peaks and valleys, extend evenly on both sides of the respective zero line N1, N2. Furthermore, the points of the struts 64a, 64b each extend in one plane.

However, this plane is inclined relative to the side surfaces of the collecting container 18 delimited by the respective strut 64a, 64b. More precisely, the planes in which the prongs of the struts 64a, 64b run are inclined relative to the side surfaces of the collecting container 18 delimited by the respective strut 64a, 64b in such a way that the plane in which the prongs extend forms the same angle with each of these planes.

Thus, the serrated section 62 extends over the 14 and 15 front side surface, which in the 14 and 15 The side surface shown in the back and the 14 and 15 side surface shown above.

Due to the inclination of the planes in which the spikes of the struts 64a, 64b run, the associated spike peaks and spike valleys compensate each other in such a way that the circumference of the container body 22 along the main flow direction 38 is constant in magnitude. The exemplary circumferences 66a, 66b, 66c in 15 are therefore the same size.

Consequently, the outer skin 32 can be designed without an elastic section. In addition, the outer skin 32 has a comparatively simple geometry, especially when it is unrolled.

The outer skin 32 is in the embodiment according to 14 and 15 made from a single piece of material, i.e. not assembled from multiple parts.

The 16 shows a sixth embodiment of the collecting container 18. The collecting container 18 according to the sixth embodiment is a variant of the collecting container 18 according to the fifth embodiment (see 14 and 15 ). Therefore, only the differences to the fifth embodiment are explained below. Identical or corresponding components are given the same reference numerals.

Again, for a better understanding of the serrated strut 64a, an imaginary zero line N1 of the serrations is drawn.

In addition, several exemplary volumes 66a, 66b, 66c are again in 16 illustrated.

In the sixth embodiment, the support structure 26 comprises only a single serrated strut 64a.

As before, the spikes of the strut 64a, ie the associated spike peaks and spike valleys, extend evenly to the sides of the zero line N1. Furthermore, the teeth of the strut 64a extend in one plane.

As already mentioned in connection with the 14 and 15 As explained, the plane in which the prongs extend is inclined relative to the side surfaces of the collecting container 18 delimited by the 64a, wherein the plane in which the prongs extend encloses the same angle with each of these side surfaces.

The effect of increasing the surface area while maintaining the same circumference of the outer skin 32 is also achieved in this way.

However, it is understood that in the example of 16 the circumference in general and in particular the exemplary circumferences 66a, 66b, 66c, are constant in amount when viewed transversely to the main flow direction 38.

In the fifth and sixth embodiments (see 14 to 16 ), corrugated struts can also be used instead of serrated struts 64a, 64b. This ensures that the outer skin 32 of the collecting container 18 has a corrugated section. Corrugated struts differ from serrated struts in that they do not have any straight sections, at least in the area of the corrugation. The above explanations apply in the same way to collecting containers 18 whose outer skin 32 has a corrugated section.

In the 17 to 19 is an area of the assembly 14 from the 1 to 6 shown in detail, in which the collecting container 18 according to the first embodiment is coupled to the motor-driven hand tool 16. This means that the collecting container 18 is fluidically coupled to the hand tool 16 via the connecting piece 20, so that an air-workpiece particle mixture can be introduced into the collecting container 18 from the hand tool 16.

In the embodiment shown, the connecting piece 20 is provided on a dimensionally stable section 68 of the outer skin 32. As a result, the collecting container 18, or more precisely the container body 22, has a comparatively high degree of dimension stability in the area of the connecting piece 20, so that the collecting container 18 can be easily handled for coupling to the hand tool 16 and for uncoupling from the hand tool 16.

The connecting piece 20 is also dimensionally stable.

Furthermore, the dimensionally stable section 68 and the connecting piece 20 are manufactured in one piece.

The free end 24 of the connecting piece 20 protrudes from the container body 22. Furthermore, a bearing block 72 is positioned on the outer circumference 70 of the connecting piece 20, via which a piece cover 74 is rotatably mounted on the connecting piece 20.

An associated axis of rotation 76, about which the nozzle cover 74 is rotatable, runs transversely to a longitudinal extension direction 78 of the connection nozzle 20.

The rotation axis 76 is spaced from the outer circumference 70 of the connection piece 20. A distance of the rotation axis 76 from the outer circumference 70 is therefore greater than zero.

Thus, the nozzle cover 74 can optionally close the connection nozzle 20 at the free end by appropriate rotation about the rotation axis 76 (see 20 ) and release (see 17 to 19 ).

The collecting container 18 can only be coupled to the hand tool 16 if the nozzle cover 74 releases the connection nozzle 20.

The coupled state is characterized in that a connection piece-side sealing section 80, which is positioned on an inner circumference 82 of the connection piece 20 adjacent to the free end 24, is in contact with a hand tool-side sealing section 84 (see 18 and 19 ).

When the nozzle cover 74 closes the connection nozzle 20, ie when the nozzle cover 74 is in the closed position, a cover-side sealing section 86 is at least partially located opposite the connection nozzle-side sealing section 80 or on the connection nozzle-side sealing section 80 (see 20 ).

In this case, a sealing element 88 in the form of a sealing lip is arranged on the connection piece-side sealing section 80.

A sealing element 90 in the form of a sealing lip is also provided on the hand tool-side sealing section 84.

The nozzle cover is preloaded into the closed position by means of a spring device 92.

The nozzle cover 74 is in the 22 and 23 shown in isolation.

The nozzle cover 74 has a closure portion 94 which is designed to selectively close the free end 24 of the connection nozzle 20.

Furthermore, the nozzle cover 74 has an actuating section 96 which comprises an actuating surface 98 which is designed to be subjected to a pressure force by means of a human finger in order to move the nozzle cover 74 from the closed position to the open position against the action by means of the spring device 92. The actuating section 96 is thus designed to manually release the free end 24 of the connecting nozzle 20.

The nozzle cover 74 is designed as a single, connected component. Accordingly, the closure section 94 and the actuating section 96 are also designed as one piece but separately from one another.

The closure portion 94 and the actuating portion 96 enclose an obtuse angle 100 in a plane of rotation, i.e. viewed along the axis of rotation 76.

In addition, the locking portion 94 and the actuating portion 96 are positioned on opposite sides of the rotation axis 76.

In other words, the closure portion 94 and the actuating portion 96 are spaced apart from each other.

Furthermore, a retaining rib 102 with a mounting slope 104 is formed on the closure portion 94.

The retaining rib 102 serves to lock the collecting container 18 in a position coupled to the motor-driven hand tool 16 (see 18 and 19 ).

The retaining rib 102 is positioned on a side of the closure section 94 facing the connecting piece 20. Accordingly, in the closed position, the retaining rib 102 projects into the interior of the connecting piece 20.

A recess 106 is also provided on the closure portion 94.

The recess 106 serves to accommodate a section of the hand tool 16 in a position of the collecting container 18 coupled to the motor-driven hand tool 16 (see 18 ).

The recess 106 is also positioned on a side of the closure portion 84 facing the connection piece 20.

The retaining rib 102 is closer to the axis of rotation 76 than the recess 106.

An outlet 108 of the motor-driven hand tool 16, which is part of the assembly 14, is in 21 to see in detail.

The outlet 108 serves to discharge the air-workpiece particle mixture from the hand tool 16. A retaining bead 112 for coupling the collecting container 18 for workpiece particles is arranged on an outer circumference 110 of the outlet 108.

The retaining bead 112 is also provided with a mounting slope 114.

Furthermore, the hand tool 16 has a contact area 116. This is designed to be contacted by the nozzle cover when the collecting container 18 is coupled to the hand tool 16.

The nozzle cover 74 can thus lock the collecting container 18 to the hand tool 16 in a situation in which the collecting container 18 is coupled to the hand tool 16. For this purpose, the holding rib 102 of the nozzle cover 74 engages behind the holding bead 112 of the hand tool 16. Furthermore, the nozzle cover 74 in the area of the recess 106 contacts the contact area 116 of the hand tool 16 at least in sections (see 17 and 18 ).

Due to the fact that the nozzle cover 74 is pre-tensioned into its closed position by means of the spring device 92, the locked state of the collecting container 18 on the hand tool 16 can only be released by the application of force.

This can be done by applying an actuating pressure force to the actuating portion 96.

By means of such an actuation, the actuating section 96 can be moved closer to the outer circumference 70 of the connection piece in a view along the rotation axis 76, so that the closure section lifts off the hand tool 16.

In this way, the nozzle cover 74 can be brought into a release position in which it releases the connection nozzle 20 at the free end 24 and with a connection cross-section of the connection nozzle zens 20 forms an angle 118 of more than 90° (see 19 ).

In such a position of the nozzle cover 74, the connecting nozzle 20 can be pulled off the outlet 108 or pushed onto the outlet 108 with little resistance. In other words, in such a position of the nozzle cover 74, the collecting container 18 can be easily coupled to the hand tool 16 and just as easily uncoupled from it.

If the nozzle cover 74 is not operated in a state in which the collecting container 18 is not coupled to the hand tool, it closes the connection nozzle 20 (see 20 ). In this position, the actuating section 96 is located on a side of the rotation axis 76 facing away from the connection piece 20.

In order to release the free end 24 of the connecting piece 20, the connecting piece cover 74 must now be actuated in such a way that the actuating section 96 is moved to a side of the rotation axis 76 facing the connecting piece 20 (see 19 ).

Above, the nozzle cover 74 and the associated devices of the collecting container 18 and the motor-driven hand tool 16 were explained using the collecting container 18 according to the first embodiment (see 1 to 6 ). However, it is to be understood that the statements regarding the nozzle cover 74 and the associated devices of the collecting container 18 and the motor-driven hand tool 16 apply equally to the other embodiments of the collecting container 18.

As shown by 24 As can be seen, the dimensionally stable portion 68 of the outer skin 32 further comprises an emptying opening 120.

The emptying opening 120 serves to remove workpiece particles from the container body 22, e.g. when machining of a workpiece is finished and the container body 22 is to be transferred back into the transport position, or when a limit filling level of the container body 22 with workpiece particles is reached during machining of the workpiece.

The collecting container 18 further comprises a closure means 122 which can be fastened to the container body 22 at least in a closed position, so that the emptying opening 120 can be selectively closed by means of the closure means 122.

In the embodiment shown, the closure means 122 is designed as a dimensionally stable lid 124.

The portion of the dimensionally stable portion 68 of the outer skin 32 surrounding the discharge opening 120 further forms a dimensionally stable frame 126 which delimits the discharge opening 120.

The closure means 122, more precisely the lid 124, is pivotally attached to the container body 22, more precisely to the dimensionally stable frame 126, via a hinge 128.

In the present case, the connecting piece 20 is also arranged on the closure means 122, i.e. on the cover 124. The connecting piece 20 and the cover 124 are formed as one piece.

Thus, the inlet opening 21 and the discharge opening 120 are positioned on the same outer skin surface of the outer skin 32.

The collecting container 18 also has a 24 only schematically shown locking unit 130, by means of which the closure means 122 can be locked in a closed position on the frame 126.

The locking unit 130 comprises a first actuating surface 130a and a second actuating surface 130b, via which the locking unit 130 can be actuated.

The first actuating surface 130a and the second actuating surface 130b are spaced apart from one another by a maximum of 15 cm. The first actuating surface 130a and the second actuating surface 130b can thus be grasped simultaneously with different fingers of a single human hand. In other words, the locking unit 130 can be actuated with a single human hand.

In the 24 The hand tool 16 is shown in a machining position. In the 24 a processing zone 132 below the hand tool 16.

The collecting container 18 is coupled to the hand tool 16. Consequently, in a use position of the collecting container 18, the hinge 128 is positioned on a side of the connection piece 20 facing away from the processing zone 132.

On the one hand, this has the effect that in the use position of the collecting container 18, ie in the 24 shown position, the force of gravity acts in the closing direction on the closure means 122 and the container body 22.

Furthermore, in a use position of the collecting container 18, ie in the 24 illustrated position, an emptying direction 134 which is perpendicular to an opening cross-section of the emptying opening 120 and points from an interior of the container body 22 through the emptying opening 120 in the direction of the processing zone 132.

More specifically, in a situation in which the closure means 122 is in an open position, the emptying direction 134 has an extension component 136 pointing vertically in the direction of the processing zone 132.

It is emphasized that the collecting container 18 is coupled to the hand tool 16 both in an open position of the closure means 122 and in a closed position of the closure means 122.

In the 25 is a variant of the embodiment from 24 The emptying opening 120 is arranged on an outer skin surface of the outer skin 32, which is located laterally with respect to the main flow direction 38.

Also in the 25 the hand tool 16 is shown in a machining position. The machining zone 132 is again located below the hand tool 16.

The hinge 128 is now arranged on a side of the emptying opening 120 facing away from the connecting piece 20. The emptying direction 134 therefore points in the direction of the processing zone again when the closure means 122 is open. In the variant from 25 the emptying direction 134 is oriented vertically. It therefore only has component 136 which points vertically downwards in the direction of the processing zone 132.

Both with the collecting container 18 according to the variant from 24 also with the collecting container according to the variant from 25 A method for emptying a collecting container 18 of an assembly 14 can be carried out using a motor-driven hand tool 16 and a collecting container 18.

In an initial state, the collecting container 18 is coupled to the hand tool 16 so that an air-workpiece particle mixture can be introduced into the collecting container 18 from the hand tool 16. This coupling is maintained throughout the entire process for emptying the collecting container 18.

In a first step, the closure means 122 is unlocked by actuating the locking unit 130.

The following is in the variant according to 24 the section of the container body 22 of the collecting container 18 which carries the dimensionally stable frame 126 is tilted upwards against the force of gravity relative to the hand tool 16 and the closure means 122. As already mentioned, the coupling between the collecting container 18 and the hand tool 18 is retained.

Now the component 136 of the emptying direction 134 points vertically downwards in the direction of the processing zone 132, so that workpiece particles can be easily removed from the interior of the container body 22.

For this purpose, the assembly 14 comprising the motor-driven hand tool 16 and the collecting container 18 can be held, for example, over a bucket or another suitable container. It is important that the hand tool 16 is held in the same position that it assumes during use for material processing.

When a sufficient amount of workpiece particles has been removed from the interior of the container body 22, that portion of the container body 22 which supports the dimensionally stable frame 126 is tilted downward again in the direction of gravity and the closure means 122 is locked to the frame 126 by means of the locking unit 130.

In the variant according to 25 the closure means 126 is folded downwards supported by gravity.

Now the emptying direction 134 points vertically downwards in the direction of the processing zone 132, so that workpiece particles can be easily removed from the interior of the container body 22.

When a sufficient amount of workpiece particles has been removed from the interior of the container body 22, the closure means 126 is returned to its closed position against gravity and locked there by means of the locking unit 130 on the frame 126.

It goes without saying that the explanations of the 24 and 25 not only apply in connection with the first embodiment of the collecting container 18, but can be combined with all embodiments explained above.

26 shows the collecting container 18 according to the first embodiment of the 3 and 4 in a different perspective representation.

In this case, 26 visible that the outer skin 32 has a light incidence section 138 which is translucent. In the illustrated embodiment, the light incidence section is translucent but not transparent.

It is made of a textile material with a white or light gray color that is dimensionally unstable. The light incidence section 138 therefore contributes to a filtering effect of the outer skin 32.

In addition, light can fall into the interior of the container body via the light incidence section 138.

In addition, the outer skin 32 has a viewing window section 140.

This is made from an optically transparent, shape-stable plastic material. The material can also be referred to as plastic film.

In the illustrated embodiment, the viewing window section 140 is sewn to the remaining sections of the outer skin 32, i.e. it is connected to the remaining sections of the outer skin 32 via a sewing thread.

It is understood that in other embodiments, the viewing window portion 140 is alternatively or additionally connected to the remaining portions of the outer skin 32 by means of a weld seam, an adhesive seam or other suitable means.

The viewing window section 140 also has an antistatic section 142, which in this case is designed as an electrically conductive coating. It is understood that the antistatic section can fill the entire area of the viewing window section 140, but does not have to.

The antistatic portion 142 is further electrically connected to an electrical connection contact 144 which is arranged on the connection piece 20.

Alternatively, the antistatic section 142 can comprise a material with hydrophilic properties, so that an electrostatic charge can be released into moist room air by means of this material. In other words, when using a hydrophilic material, a potential equalization can take place between the antistatic section and the humidity of the room air.

The electrical connection contact 144 is designed to enable electrical potential equalization between the antistatic section 142 and the hand tool 16.

In this way, an electrostatic charge of the viewing window section 140 is reliably avoided or at least reduced to such an extent that the function of the viewing window section 140 is not restricted.

In the present embodiment, both the viewing window section 140 and the light incidence section 138 are arranged on an outer skin surface of the outer skin 32, which is located laterally with respect to the main flow direction 38.

The light incidence section 138 is formed on a first outer skin surface 146 of the outer skin 32 and the viewing window section 140 is formed on a second outer skin surface 148 of the outer skin 32.

The first outer skin surface 146 and the second outer skin surface 148 adjoin one another at an outer skin edge 150.

The light incidence section 148 and the viewing window section 140 thus delimit a transmitted light zone 152 which extends inside the container body 22.

The transmitted light zone 152 comprises at least one viewing axis 154 which connects at least one point of the light incidence section 138 with at least one point of the viewing window section 140 in a straight line.

Light can therefore enter the interior of the container body 22 through the light incidence section 138. This enables a user of the collecting container 18 to visually determine the fill level of the collecting container 18 with high precision through the viewing window section 140.

Optionally, the viewing window section 140 is provided with a fill level scale 156.

It is understood that the same effects and advantages can also be achieved if the light incidence section 138 and the viewing window section 140 are formed on outer skin surfaces of the outer skin 32 that are at least partially opposite one another. This configuration also results in a straight line of sight that connects at least one point of the light incidence section 138 with at least one point of the viewing window section 140.

27 shows a further variant of the collecting container 18 according to the first embodiment of the 3 and 4 .

In this variant, the closure means 122 designed as a cover 124 is made of a transparent, dimensionally stable plastic material. The cover 124 thus encompasses the light incidence section 138.

Thus, the light incidence section 138 and the connection piece 20 are arranged on the same outer skin surface.

The viewing window section 140 is realized in the same way as in the embodiment according to 26 .

After the variant from 27 Since both the light incidence section 138 and the viewing window section 140 are made of a transparent material, the function of the light incidence section 138 and the viewing window section 140 can also be reversed.
