Description

Operating handle for structural elements such as windows, doors and the like

Technical Field

The present invention relates to a steering handle for a structural element such as a window, a door or the like.

Background

Many variants of operating handles for operating windows and doors are known. They usually have an elongated drive element which can move an actuating device, such as a window gear, in the sash or door leaf by means of a handle. The drive element is usually designed as a square.

In order to open and close a window or door, it is necessary to transmit a pulling or pressing force to the sash or door leaf in addition to the rotational movement. For this purpose, the connection between the handle and the drive element is designed such that they are connected to one another axially and rotationally fixed after assembly.

It is known to implement operating handles without rosettes on the sash and the door leaf. However, this results in a very limited structural space for the mechanical elements between the handle and the window mechanism. Furthermore, the fixing of the drive element to the handle is usually effected by means of a countersunk screw. If a lock is also provided in the associated operating handle, the countersunk-head screw is screwed in from above due to the positioning of the lock cylinder, which is visually unattractive.

A steering handle is known from EP 1683933B 1, in which the drive element can be anchored in the handle by a locking or clamping element by pushing the drive element into the handle.

SUMMERY OF THE UTILITY MODEL

The object of the utility model is to provide a control handle which can be connected to a window or door leaf particularly simply and preferably without visible screws, wherein at the same time the control handle can be realized without a wreath.

An actuating handle for a structural element, such as a window, a door or the like, is proposed, which has a drive element connected to the handle in a rotationally fixed manner and a substructure arrangement for mounting on a window or door frame, wherein the drive element can be connected to the substructure arrangement. According to the utility model, the handle has a cavity through which the drive element extends axially outwards, the substructure arrangement has a complementary-shaped recess for the insertion of the drive element, and the substructure arrangement is completely insertable into the cavity and has at least one pivotably mounted, spring-loaded locking or clamping element which can be connected to the drive element in a force-fitting, form-fitting and/or frictional manner.

Thus, the handlebar according to the utility model can be realized without visible screws and preferably without wreath. The drive element is connected to the handle in a rotationally fixed manner. The two parts are glued or otherwise non-detachably connected to each other. Thus, a countersunk screw for fixing the drive element to the handle is not required. At the same time, the drive element extends outwardly through the cavity of the handle for connection with a window or door mechanism.

The substructure means is designed to complement the cavity on its circumferential surface and can thus be completely accommodated by the cavity. The cavity is thus axially limited in the mounted state by the opening contour on the side facing the window or door. The cavity extends from the opening profile into the handle and may have a shoulder surface or other internal axial restriction therein. The substructure arrangement is designed to accommodate the drive element and at the same time to allow the introduction of the drive element into the window or door mechanism, wherein the drive element can be pushed through the recess along its longitudinal axis. When the operating handle is mounted on a window or door, the substructure means is located entirely between the opening contour and the inner boundary surface.

The substructure means is used to mechanically connect the handle to the sash or door leaf. It is conceivable that the substructure is screwed onto the sash or the door leaf and that a locking, form-locking and/or frictional connection is achieved between the handle and the substructure by inserting a drive element. Since the drive element is connected to the handle in a rotationally fixed manner, the handle is also connected to the sash or door leaf via the substructure arrangement. Since the substructure means may be positioned completely in the cavity, the handle may be closed directly with the opening profile or with a gap closure with the sash or door leaf. The actuating handle can thus be realized without a wreath, since the substructure means is not visible in the mounted state of the handle.

The understructure means has a groove, which preferably extends completely through the understructure means in the axial direction, so that the drive element can be inserted into the sash or door leaf through the understructure means. A drive element is provided projecting through the recess to establish an axial connection with the substructure installation. For this purpose, at least one locking or clamping element is arranged in the recess and is designed to establish a connection therewith by pushing in the drive element. Preferably, this is achieved by inserting the drive element into the recess and there connecting the locking or clamping elements to each other, as described in EP 1683933B 1. The locking or clamping element allows a variable orientation upon insertion of the drive element by means of the elastic bearing, so that the movement of the drive element can be followed in order to connect the two elements to one another. At the same time, pull-out can be prevented by wedging of the locking or clamping element with the drive element. Furthermore, due to the arrangement of the locking or clamping elements in the substructure installation, there is no need to provide wreaths or other elements which increase the installation space and which project outwards on the door leaf or sash. The window sash protrudes outward. However, a firm connection between the drive element and the door or window gear is possible.

In an advantageous embodiment, the substructure installation has at least two cams facing away from the handle for insertion into complementary cam openings of the window or door frame. Alignment of the substructure installation on the sash or door leaf can be achieved by means of a cam. For this purpose, it is equipped with complementary cam holes into which the cams are introduced. The substructure apparatus is secured by tightening it in a subsequently determined direction, and the handle attached to the substructure apparatus is also properly aligned for use.

The cavity of the handle can also have a radially inner surface with a latching recess, wherein the substructure means has at least one latching web extending in the radial direction for releasable latching into the latching recess. The radial inner surface surrounds the cavity of the handle and allows the latching tabs to latch into the latching recesses when the handle is actuated. In this case, the latching lug is connected to the substructure device in a rotationally fixed manner, so that it always remains in its position regardless of the rotation of the handle. If the handle is rotated, the detent recess follows the rotation and can be latched in the detent recess depending on its arrangement on the radial inner surface. The latching tabs are preferably radially elastic, so that they can be easily snapped in and also easily released from the latching recesses. The purpose is to provide tactile feedback to the user to a particular rotational position while holding the handle easily in that position.

For the substructure arrangement, it may be useful to have two diametrically opposed latching webs, the radially inner surface having at least four latching recesses which are spaced uniformly from one another. In this case, the latching tabs can simultaneously latch into the latching recesses lying opposite one another. When four latching recesses are used, a latching on the order of 90 ° results. A significantly finer latching, for example in the order of 45 °, is also achieved by a greater number of latching depressions.

It is particularly advantageous if at least one latching tab is arranged on a latching element which is arranged on the side of the substructure means facing the handle and serves as a mounting stop for the handle. The handle then occupies a predetermined axial position when installed, forming a coordinated and non-knurled shape.

Preferably, the latching element is axially elastic in order to exert an axial pretensioning force after the actuation handle is assembled. Any axial play can thereby be reduced or completely compensated.

Particularly preferably, the substructure installation has a rotatably mounted insert in which the locking or clamping element is arranged. The handle can then still rotate freely, but is held axially by the locking or clamping element regardless of its rotational position. The support of the insert can be achieved by simple sliding bearings or corresponding holes with a suitable fit.

In an advantageous embodiment, at least one locking or clamping element has a clamping frame with an opening complementary to the contour of the drive element for receiving and closing the drive element. The drive element may extend through an opening of the clamping frame. Due to the pivotable elastic bearing, the clamping frame can align itself obliquely to the drive element after insertion of the drive element (depending on the size of the opening of the drive element). In particular, in the case of a sharp profile of the opening, the clamping frame can be wedged with the drive element when the drive element is moved in the opposite direction. The clamping frame can be designed such that if the opposing force continues to move the drive element out, the clamping frame becomes even more inclined and the two elements are thereby even more strongly wedged into each other.

It is furthermore advantageous if the clamping frame is pivotable between a first position, in which a surface normal of a plane spanned by the clamping frame extends obliquely to the longitudinal axis of the drive element, and a second position, in which the surface normal extends parallel to the longitudinal axis. The pivot axis may extend perpendicular to the longitudinal axis and thus transversely through the longitudinal axis of the drive element. For example, the pivot axis may be diagonal to the cross-section of the drive element. Thus, when the clamping frame is tilted, the clamping frame can be wedged onto two surfaces of the drive element which are adjacent to each other. The drive element can be guided through if the clamping frame is at least largely in the second position. Due to the elastic support, the clamping frame is preferably always pushed into the first position, but the pushing of the drive element pushes the clamping frame in the direction of the second position.

In an advantageous embodiment, the handle has an opening for passing a tool for moving the locking or clamping element against the spring force. The tool can also move the locking or clamping element and there move the clamping frame or another suitable element against the spring force in order to release the drive element from its axial fixation.

The drive element may have a projection on the longitudinal side, wherein the recess has a radially outward cutout on the limiting edge, which cutout is designed for the projection to slide through. By positioning the partial cut-out at a suitable point on the limiting edge, the drive element can only be inserted into the recess in a single rotational position and pushed in completely. The tab can then be moved past the associated restraining edge through the cutout. If the drive element is not correctly aligned, the projection may come into contact with one of the limiting edges and therefore the drive element does not subsequently reach the locking or clamping element either. This prevents incorrect assembly.

Detailed Description

Fig. 1 shows a steering handle 2 for windows, doors or the like. Here, a handle 4 is shown, the handle 4 having a cavity 6, a drive element 8 extending outwardly from the cavity 6. The drive element 8 is here designed as an elongated square and is glued or otherwise non-detachably connected to the handle 4. The substructure installation 10 is shown separately here, and the substructure installation 10 can be connected to a window or door frame. It has a recess 12, through which recess 12 the drive element 8 can be inserted, so that the drive element 8 projects at its end which is not visible here. The substructure means 10 is complementary to the cavity 6, so that it can be inserted completely into the cavity 6.

Fig. 2 shows the actuating handle 2, wherein the substructure means 10 is pushed completely into the cavity 6 and is approximately flush with the opening contour 14 of the cavity 6. The drive element 8 protrudes significantly beyond the opening profile 14 and can therefore be connected to a window or door gear arranged in a window or door frame. The lower structure arrangement 10 is provided with a cam 16 extending over the opening profile 14. As shown in another figure below, the cam 16 may be inserted into a corresponding cam hole of a window or door frame to fix the orientation of the substructure installation 10.

Fig. 3 shows an exploded view of the substructure installation 10. The lower structure 10 has a lower part 18, the cam 16 being arranged on the lower part 18. The insert 22 is inserted through a circular hole 20, the circular hole 20 having a first lateral surface 24, a second lateral surface 26 having a larger diameter and an annular shoulder surface 28 therebetween. The lower part 22 is inserted into the hole 20 in such a way that the first lateral surface 24 can rotate in the hole 20 and the shoulder surface 28 rests on the side of the lower part 18 facing the cam 16. Here a recess 12 to which the drive element 8 is connected. Thereby, the lower part 22 follows the rotation of the handle 4 in the fully mounted state.

The latch element 30 is inserted onto the first lateral surface 24 such that the latch element 30 and the insert 22 enclose the lower component 18. The latching element 30 has two opposing latching webs 32, which are designed to be radially elastic. In addition, the lower member 18 has a plurality of holes 34 that allow the lower member 18 to be threadably connected to a window or door frame. The hole 34 is then covered by the latch element 30. In order to connect the latching element 30 precisely to the lower part 18, the lower part 18 has two projections 36 arranged opposite one another, which surround corresponding recesses 38 of the latching element 30. The two elements 18 and 30 are preferably designed as a press fit, so that the latching element 30 can be fixedly mounted on the lower part 18. The cover ring 40 snaps together with the lower member 18 and holds the assembly of the lower member 18 and the insert 22 together.

Furthermore, the latching element 30 can serve as an axial stop for the handle 4. In order to absorb axial play which may occur in the proposed connection, the latching element 30 is also designed to be axially resilient. The latching tab 32 projects a short distance relative to the handle 4 and is deformed by this distance when the handle 4 is mounted. The distance may be about 0.2 mm. This generates a pretension of approximately 50N. This force can dampen any axial play that may occur.

Fig. 4 shows a part of the window frame 42 with the substructure installation 10 installed, whereby the fastening screws 44 and the latching elements 30 are shown, respectively. After tightening the screw 44, the catch element 30 is placed and the handle 4 is then pushed onto the substructure installation 10 for inserting the drive element 8.

As described above, the cam 16 may be inserted into the cam hole 46 of the window frame 42. As shown in fig. 5. Furthermore, mounting holes 48 for the screws 44 and mounting openings 50 for the drive element 8 are shown here. The cam holes 46 and mounting holes 48 for the screws 44 may be made using a drill template or drill jig.

Fig. 6 shows the insert 22 in an exploded view. Here, the direction is opposite to that shown in fig. 3. The insert 22 has a rotor 52, the rotor 52 having a first lateral surface 24. At the inner end, an inclined bearing surface 54 is arranged, against which a clamping frame 56 is pressed by a compression spring 58. Thus, when the clamping frame 56 is located on the bearing surface 54, the surface normal 60 of the plane spanned by the clamping frame 56 is inclined about the two spatial directions to the axis of rotation 62 of the insert 22, wherein the axis of rotation 62 is at the same time the longitudinal axis of the drive element 8. This is referred to previously as the "first position". This is the position in which the clamping frame 54 is in an unloaded state when the compression spring 58 pushes the clamping frame 54 against the support surface 54.

When the drive element 8 is inserted, the clamping frame is slightly erected so that the surface normal 60 is substantially parallel to the axis of rotation 62. This is referred to previously as the "second position". The drive element 8 can then be slid over the limiting edge 64 of the clamping frame opening. However, due to the spring force, the clamping frame 56 is squeezed back into the first position again and the limiting edge 64 is wedged with the drive element 8.

The cover 66 may snap over the rotor 52 and retain the compression spring 58 and the clamping frame 56 in the insert 22.

Fig. 7 shows the substructure installation 10 in a side view and in a sectional view. Here the inclined position of the clamping frame 56 can be seen.

Fig. 8 shows the substructure installation 10 in the assembled state, with the side facing the handle 4.

Fig. 9 shows the substructure installation 10 from the opposite side, as it faces the window frame 42. The substructure installation 10 is connected in a rotationally fixed manner to the window frame 42 by means of the cam 16. The locking element 30 in fig. 8 is therefore also arranged rotationally fixed.

As shown in fig. 10, the cavity 6 of the handle 4 has four detent recesses 70 on the radial inner surface 68, each of which is distributed uniformly about the axis of rotation 62, offset by 90 ° from one another. When the handle 4 is rotated, the rotatably mounted insert 22 rotates with the handle and the snap tabs 32 extend on the radially inner surface 68. If they reach the latching recesses 70, they snap into them. Due to their radially elastic design, the latching tabs 32 can also be easily released again from the latching recesses 70.

Fig. 11 shows a part of the handle 4 with the drive element 8. Here, it can be seen that the longitudinal sides of the drive element have their projections 72. In the orientation of the drive element 8 shown here, the projection 72 cannot be inserted into the groove 12, but rather abuts an edge face of the groove 12. However, the groove 12 has a radial cut-out 74 at one location that allows the protrusion 72 to pass through and thus the drive element 8 to be fully inserted into the substructure apparatus 10. The handle 4 can therefore be pushed into the substructure installation 10 in only one, defined orientation and locked there. This prevents incorrect assembly.

As shown in a slightly larger cross-sectional view in fig. 12. In this case, the projection 72 rests on the insert 22, so that the drive element 8 cannot reach the clamping frame 56 and therefore cannot be locked. In order that the clamping frame 56 does not have to be aligned during the assembly of the substructure installation 10, the clamping frame 56 has four recesses for pushing the projections 72 through.

Fig. 13a and 13b show that, to release the drive element 8 from the lower structure 10, the handle 4 has an opening 76 through which a tool 78 can be inserted into the handle 4 and the lower structure 10. There, the clamping frame 56 can be moved from the first position toward the second position, which releases the connection to the drive element 8 and thus makes it possible to detach the substructure installation 10 from the handle 4.

The lower part 18 and the cover ring 40 are constructed such that they form an inclined channel 80 for the tool 78. The tool 78 is guided from the outside below the clamping frame 56 and is lifted slightly by turning the clamping frame against the spring force of the compression spring 58, and the handle 4 can be detached together with the drive element 8.

Since the drive element 8 always has the projection 72 at the same point, it is ensured that the removal hole in the rotor 52 is always aligned with the opening 76, so that the tool 78 can always pass through both parts. In order to avoid having to fit the cover 66 of the insert 22 in an oriented manner, the cover has two opposite disassembly openings. Furthermore, in order to prevent misalignment between the window or door gear and the handle 4, two opposing disassembly openings may be provided in both the lower part 18 and the cover ring 40. In the event of a faulty operation, the handle 4 can thus be rotated by at least 90 ° and detached again.

The present invention is not limited to one of the above-described embodiments, but may be modified in various ways.

All features and advantages which are derived from the claims, the description and the drawings, including structural details, spatial arrangements and method steps, are essential to the utility model, both individually and in various combinations.
