Description

The invention relates to a household refrigerator with an interior that is designed to accommodate food. The interior space is delimited by the walls of an inner container. The household refrigerator also includes a fresh food container which is arranged in the interior. The freshness container can be closed with a lid. In addition, a storage device is formed with which the lid can be raised and lowered in the interior for opening and closing the fresh food container. The cover can be operated with an operating element.

Such configurations are known from the prior art. So shows the WO 2011/026749 A2 a corresponding refrigerator with a vegetable compartment. A tray for holding the vegetables can be put in and taken out of the interior. This bowl can be covered from above by a lid. In the closed state, the lid rests on the inclined upper edges of the shell. A further plate is arranged above the cover, on which a front strip is formed, on which an operating element is movably positioned. The control element can be moved parallel to the front strip and is coupled to an inclined guide track in the form of a slot that is formed in the cover. Depending on this displacement of this slide, the cover is then lifted, which is coupled to the plate arranged above it via a corresponding mechanical coupling.

In addition, from the DE 40 40 341 C2 a fresh food box with a lockable lid is known. This box can also be used in an interior of a household refrigerator.

In both of the designs known from the prior art, provision is made to protect the items to be cooled, for example in the form of vegetables, salads, meat, fruit and the like, from drying out undesirably quickly. The one in that Problems arising are already in the context of the DE 4040 341 C2 adequately explained.

the KR 2002 0034 301 A describes a container which can be closed with a lid. The container can be placed in a refrigerator to keep food stored in the container cool. A handle that can be rotated about an axis is arranged on the cover. A base body of the handle has tabs which project in the radial direction and which, when the lid is closed, engage in grooves which are formed in a wall of the container. When the lid is closed, a pin protruding from the tabs engages in a recess which is formed in the wall of the container.

the WO 2005/064 248 A1 describes a refrigerator which has walls with guide rails. A container can be moved out of an interior space of the refrigerator or pushed into the interior space along these guide rails. A mechanism for lifting a lid of the container includes a gear which is coupled to a shaft of a motor. A rack in which the gear meshes is attached to an upper side of the cover. As operating elements for moving the lid, switches are attached inside or outside the refrigerator. The cover can be raised by pressing a first switch and lowered by pressing a second switch.

From the EP 2 923 161 B1 a household refrigerator according to the preamble of claim 1 is known.

It is the object of the present invention to create a household refrigerator in which the cover can be operated in a more user-friendly manner.

This object is achieved by a household refrigerator which has the features of claim 1.

A household refrigeration device according to the invention comprises an interior space for holding food which is delimited by the walls of an inner container. In addition, the household refrigerator comprises a fresh food container that can be attached in the interior. Food can be placed in the fresh food container. The fresh food container can be closed with a lid. The household refrigerator also has a storage device, by means of which the lid can be raised and lowered in the interior for opening and closing the fresh food container. This cover can be operated with an operating element. An essential idea of the invention is to be seen in the fact that the operating element for actuating the cover can be rotated about an axis on an actuation path and can be locked in at least one rotational position along the actuation path. By means of such a configuration, a storage position of the cover associated with or associated with a specific rotary position of the operating element can thus be locked. This prevents an undesired change in this set position of the cover. In particular, such a latched position of the control element also ensures that a user who removes food from the interior when the refrigerator is open or equips the interior with food and thus possibly also walks along the control element unnoticed or contacts it, does not immediately see it in his Changed position and thus undesirably caused a change in position of the cover. Since the invention prevents an undesirable smooth rotation change of the operating element in a rotary position characterizing the specific position of a cover, a more user-friendly handling of the domestic refrigeration appliance as such is also achieved. The fresh food container comprises in particular a lid and a drawer.

It is preferably provided that a first rotary position in which the operating element is locked is an end position of the operating element at the end of the actuation path. In this context, it can be provided that in such an end position the cover is arranged in the fully open storage position or the fully closed storage position.

It is preferably provided that at least two different first rotational positions, in which the operating element is locked, are formed, which represent the two possible different end positions of the operating element at the respective ends of the actuation path. Such a configuration can in particular achieve that both the completely closed state of the cover and the completely open state of the cover are correlated with an individually locked rotary position of the operating element. It is precisely these two very exposed layers of the cover that are therefore held in a very secure position and fixed.

When the lid is in the completely closed position, the moisture then remains in the fresh-keeping container.

When the lid is completely open, improved and faster drying of the fresh food container is then made possible.

In principle, it is possible to set an ambient humidity different to the remaining partial volume of the interior space in the fresh food container, which is advantageous for specific foods, for example vegetables or fruit, in order to be able to keep them fresh longer in this fresh food container.

This is particularly advantageous in so-called no-frost household refrigeration devices, in which, due to the refrigeration operating principle, there is drier air in the interior and, as a result, foods such as fruit or vegetables in particular lose their freshness more quickly. Such a configuration with a fresh food container is particularly advantageous for such devices, since the above-mentioned aspects can be prevented.

It is preferably provided that a second rotational position in which the operating element is locked is formed and this is an intermediate position formed between two end positions. This means that this second rotary position defines a position in which the operating element has not arrived at one of the two possible ends of the actuation path. With at least one such intermediate position, the cover can thus be positioned in a partially open position, so that a different position can also be set here as required and situation-specific. This can be advantageous for maintaining the moisture content in the freshness container, which may possibly be dependent on the type and / or quantity of the stored goods in the form of the foodstuffs that are brought into the freshness container.

It is provided that the operating element has a disk-shaped base body which has a guide slot that encompasses regions around the axis of rotation and that specifies the length of the actuation path. The guide link can preferably be implemented as a curved, in particular banana-shaped configuration.

A sliding block external to the operating element engages in the guide link, which locks the operating element in the at least one rotational position. Such a configuration realizes a highly effective, robust and yet very simply constructed mechanical operating principle. User-friendly actuation is achieved, as is mechanics with fewer components and a compact design. In addition, the specific shape of the guide link and the coupling with a sliding block also enable a very jolt-free and smooth movement of the operating element, so that the rotary movement can also be performed very ergonomically by a user.

It is particularly advantageous that the guide slot has a bulge directed radially outward at the slot provided for locking the rotational position and thus at a specific point of the actuation path, on a radially outer edge contour that delimits the guide slot and defines it in a shape-specific manner. Due to this form specification, this sliding block virtually automatically guides into a depression or trough of the when this rotational position to be locked is reached Guide link geometry. The latching is also made possible in a very simple manner by a full seat then produced in this way.

In particular, the shape of the sliding block is adapted to this outwardly directed bulge, so that the sliding block has as large an area as possible against this bulge. Undesired position tolerances and the associated wobbling of the components in this locked rotational position are avoided.

It is particularly advantageous that the sliding block is radially pretensioned in the rotational position to be locked. The above-mentioned advantages are particularly favored by this.

In particular, it is provided that at least one recess adapted to the shape of the guide slot is formed on the base body, radially further outward from the guide slot of the operating element, which extends at least in the area of the slot formed for locking the intended rotational position. This is done in such a way that a radially deformable separating web is formed between the guide slot and the recess. This configuration is particularly noteworthy because, on the one hand, a geometrically very precise and specifically formable guide slot is defined, and on the other hand, the delimitation of the guide slot with the separating web also creates a multifunctional component which, thanks to its deformability, significantly promotes locking. It is therefore integrated in this base body through the design and positioning of the guide slot on the one hand and the at least one recess on the other hand, creating a latching device that is highly effective and functional. The sliding of the sliding block in the guide link also on this separating web is guided in a mechanically stable manner outside the bulge which enables the latching. In the area of this bulge, however, when the sliding block slides along, the position of the base body in relation to this sliding block external to the operating element automatically enables this separating web to be pressed radially outward by the sliding block. If this sliding block approaches this bulge as it slides along in the actuation path, the radial force of the sliding block on this separating web is successively increased, so that when it is reached and snapped into the bulge, in particular the radial preload is very defined. A very uniform increase in this radial prestressing force on the way to the bulge is thus also carried out.

It can then be provided that, when the sliding block is snapped into the bulge, the separating web is held in its maximally radially outwardly pushed position and thus a maximum radial pretensioning is also given. However, it can also be provided that with the snapping of the sliding block into the bulge and the locked rotational position state thus generated, a slight radially inward orientation of the separating web occurs, and yet a sufficient radial preload is built up to maintain the locked state.

It can also be provided that the guide link is tapered shortly before the bulge, in particular in such a way that the radial inside width is smaller than a radial outer dimension of the link block. As a result, when the sliding block slides through such a narrow point, the separating web is then pressed outwards and when the sliding block moves further in the guide slot, the sliding block then slides into the bulge. It is then anchored there and in this latching position the separating web at the narrow point is automatically returned to its starting position.

The bulge is preferably designed so that the sliding block is positioned snugly therein.

It is preferably provided that the separating web is radially thinner at the bulge than outside the bulge. This further enhances the deformability and improves the abovementioned advantages when the sliding block is moved along the actuation path before the bulge is reached.

It is preferably provided that two separated recesses adapted to the shape of the guide slot are formed in the base body, lying radially further outward in relation to the guide slot of the operating element. These two recesses extend on the same radius path, which means that they are arranged in the direction of rotation around a central axis, which also represents the axis of rotation of the base body, at the same radial distance from this axis of rotation. In this configuration with the two separated recesses, a spacer web is then formed between the recesses in order to separate them from one another. This spacer bar is preferably formed in a mean fifth of the length of the total length of the actuation path and thus also the length of the guide slot. It is preferably formed essentially in the middle of the length of the guide link which is measured in the direction of rotation about the axis of rotation. This configuration creates a symmetry that is to be emphasized, which on the one hand significantly favors the stability of the separating web, and on the other hand greatly favors the mechanical operating principle for the radial deformation of the separating web at specific points. As a result, mechanical leverage for the radial deformation of the separating web outwards can be achieved in a targeted and local manner, so that the sliding block also snaps into a bulge that defines a locked rotational position.

The separating web is thus stabilized in the center in particular by this spacer web, so that it is both positionally fixed and mechanically stabilized here. This prevents a relatively long separating web from breaking, which would then not be supported radially by such a spacer web.

It is preferably provided that at least one curved, strip-shaped recess extends beyond one end of the guide link in the direction of rotation around the axis of rotation. This configuration is also to be emphasized, since it enables a separating web that can be moved or deformed in the radial direction precisely at the point of rotation at which a bulge is formed in the guide slot. If the recess were also terminated in the radial extension of the bulge in the guide slot, this would result in possibly undesirable stabilization, which would impair the possibility of radial deformation of the separating web towards the outside.

It is preferably provided that the disk-shaped base body has an indentation, in particular a wedge-shaped cutout, on its jacket wall, which is designed as an engagement area for a user to rotate the base body. Such a shape-specific design of the base body has several advantages. On the one hand, unwanted slipping of the user when actuating the control element and thus when rotating is prevented. Because the jacket wall of this disc-shaped Base body has a relatively small height, the contact area with, for example, a finger of a user is also relatively small. Especially when a certain amount of moisture is still deposited on this jacket wall, this area of engagement can prevent undesired slipping when the base body is rotated.

Another advantage to be mentioned is given by this indentation in that it also allows the possible end positions of the operating element to be visually recognized. Since the control element and thus also the preferably designed disk-shaped base body is recessed in some areas between the cover and a partition wall arranged above and only a part of this disk-shaped base body can be seen and operated on the front side by a user, a positional momentary arrangement of the base body is possible through this engagement area recognize. In particular, the base body is arranged in such a way that this engagement area extends outwardly from the space between the cover and the partition wall and is thus also easily contactable and actuatable by a user. If this engagement area is designed in terms of size so that its two ends occurring in the circumferential direction on the jacket wall are spaced apart in an angular segment which corresponds to the angular segment of the actuation path, the respective ends can also be an end position of the actuation path through the circumferential width of the engagement area on the jacket wall be assigned. If, for example, the base body is then oriented in such a way that a first end of the engagement area is arranged shortly before the immersion or flush with the space formed by the cover and the partition above it, this end position can also be easily recognized optically by a user on the base body . The same then also applies to the second opposite end position.

It is preferably provided that an engaging element arranged eccentrically is formed, in particular integrated, on an underside of the base body facing the cover. This engagement element engages in a guideway in the cover, whereby depending on the rotational movement of the base body in the guideway, the actuation of the cover is enabled and thus the cover is closed, partially opened or fully opened by the displacement of the engagement element in the guideway.

It is preferably provided that the top of the base body faces a partition which separates the fresh food container from the remaining partial volume of the interior space and is rotatably mounted on the partition.

It is preferably provided here that the base body has a central passage or a central hole into which a retaining pin formed, in particular integrated, on the underside of the partition wall engages. A non-destructive detachable connection can preferably be provided here. In this context, the retaining pin can be a locking pin or a plug pin or the like. In the assembled state, the base body is then also rotatably mounted about this retaining pin, so that the retaining pin also represents or includes the axis of rotation. The sliding block external to the operating element on an underside of the partition is spaced apart and arranged and designed separately from this retaining pin. The retaining pin and the sliding block external to the operating element, which is also designed to be integrated, in particular, on the underside of the partition, thus have functionally different tasks.

It is preferably provided that the sliding block external to the operating element is arranged on the underside of the partition wall facing the base body, eccentrically to a mounting point of the base body on the partition wall having the axis of rotation. In this context, the storage point is defined in particular by the retaining pin.

In a further advantageous embodiment it is provided that the base body has a plurality of movement stabilizing elements arranged on the same radius path on the top side facing away from the cover. Here, too, these movement stabilizing elements are thus arranged with the same radius when viewed in the direction of rotation around the axis of rotation. In particular, it is provided here that this radius path, on which the movement stabilizing elements are arranged, is arranged with a greater radius than the guide link and / or the recesses in the base body. The movement stabilizing elements are thus preferably arranged relatively far outward, in particular in a radius interval which is greater than 80%, preferably greater than 90% of the radius of the jacket wall of the base body. This configuration, in addition to the central, central mounting of the base body, in particular on the partition, enables rotational movement stabilization, see above that in particular tilting about a horizontal position in which the base body is preferably located is prevented. An undesired displacement of the base body out of this central position in the horizontal direction can also be prevented in this way. This achieves a very wobble-free movement of the base body.

The movement stabilizing elements are preferably pins that engage in a stabilizing track. The stabilization track is in particular a stabilization track formed on an underside facing the base body of a partition separating the fresh food container from the remaining partial volume of the interior space.

The locking of a specific rotary position is thus also associated with a haptically perceptible resistance, so that the user can also very easily and intuitively recognize the specific rotary position defined in each case. To generate this latching and the haptically perceptible resistance, a type of brake, for example in the form of a silicone brake, in the form of a type of gearwheel or the like with a counter-contour can also be formed on the partition. It can also be provided that the lockable rotary positions specific here on the operating element, in particular the disk-shaped base body, are optically marked so that they are even more easily perceptible and approachable by a user.

In Fig. 1 is shown in an exemplary representation of a household refrigerator 1, which is designed as a combined fridge-freezer. The household refrigeration appliance 1 comprises a body 2 with an inner container 3. The inner container 3 delimits with its walls a first interior space, which is a cooling space 4, and a second interior space which is arranged below and is separated therefrom and which is a freezing space 5. The cooling space 4 is generally used for frost-free cooling of items to be cooled, preferably at temperatures between + 4 ° C. and + 8 ° C. However, the cooling space 4 can also be designed as a zero-degree compartment, in particular for keeping fruit or vegetables fresh. The cooling space 4 is accessible when the door 6, which closes the space 4 at the front, is open.

The freezer compartment 5 is generally used for deep-freezing frozen goods, for example at -18 ° C. The freezer compartment 5 is accessible when the freezer compartment door 7 is open.

In the cooling space 4, a refrigerated goods or fresh food container 8 is mounted so that it can be pulled out, which can be closed by means of a cover 9 mounted over the fresh food container 8. As shown, an additional cover 10, for example in the form of a glass compartment floor, can be arranged over the cover 9.

The inner container 3 has two opposite vertical side walls 3a and 3b.

It is preferably provided that a partition 11 is arranged between the lid 9 and the cover 10. This separates the fresh-keeping container 8 from the remaining partial volume of the interior or cooling space 4.

The lid 9 can be raised and lowered in the interior 4 by means of a storage device 12 for opening and closing the fresh food container 8. In particular, the storage device 12 comprises an operating element 13 with which the cover 9 can be actuated. The operating element 13 can be rotated about an axis on an actuating path for actuating the cover 9 and can be locked in at least one rotational position along the actuating path.

The operating element 13 is arranged in an intermediate space between the cover 9 and the partition 11 and extends only partially forward out of this intermediate space, so that it is freely accessible towards the door 6 and thus at the front and can be operated by a user.

In Fig. 2 an assembly is shown which shows the cover 9, the partition 11 and the operating element 13. The operating element 13 comprises a disk-shaped base body 14, which will be explained in more detail below.

The partition wall 11 arranged in the vertical direction and thus in the y-direction above the cover 9 is designed in the exemplary embodiment shown in such a way that it also serves as a carrier plate for the cover 9. In this exemplary embodiment, the cover 9 is therefore exclusively mounted on this partition 11 and can be moved relative to this partition 11 in order to then be raised or lowered with respect to a drawer 15 of the fresh food container 8 in order to set the open or closed state of the fresh food container 8 can.

The fresh food container 8 comprises the lid 9 and the drawer 15.

As shown in the perspective view from below in Fig. 3 As can be seen, the cover 9 comprises, on the edges 9a and 9b facing the side walls 3a and 3b, engaging brackets 16, 17, 18 and 19, which engage in downwardly projecting guide tabs 20, 21, 22 and 23 of the partition 11. In these guide tabs 20 to 23 guide tracks are designed to run obliquely, as shown in the side view in FIG Fig. 4 is shown. In this side view, the tabs 20 and 21 are shown, which have guide tracks 20a and 21a. The elements or brackets 16 and 17 engage in this.

In the side view according to Fig. 4 a state is shown here in which the cover 9 is shown in a completely closed end position. The brackets 16 and 17 are arranged in this connection at a lower front end of the guide tracks 20a and 21a.

This in Fig. 4 The operating element 13, also shown, with its disk-shaped base body 14 is mechanically coupled to the cover 9 in such a way that the cover 9 is displaced as a function of a rotary movement about an axis A. This means that, for example, based on the in Fig. 4 As shown in the closed state of the cover 9 by rotating the base body 14 about the axis A, a displacement of the cover 9 relative to the partition 11 is achieved, while the brackets 16 and 17 slide back and up in the guide tracks 20a and 21a, so that the cover 9 is raised relative to the drawer 15 upwards.

As shown in Fig. 4 As can be seen, this disk-shaped base body 14 extends over a front edge 11a of the partition wall 11 and can thus be easily grasped and operated by a user.

In Fig. 5 FIG. 3 is an exploded view of the assembly according to FIG FIGS. 2 to 4 shown. On an underside 11b of the partition wall 11, a retaining pin 24 is integrally formed, which represents a mounting point of the disk-shaped base body 14. The disk-shaped base body 14 is, in particular, rotatably mounted on the partition wall 11 so as to be detachable and non-destructive. For this purpose, the disk-shaped base body 14 comprises a central hole 25 through which the retaining pin 24 extends in the assembled state. The axis of rotation A also runs through this central hole 25. In particular, it is provided that the attachment of the disk-shaped base body 14 is secured by a securing element 24 a, which couples with the retaining pin 24.

On an upper side 9c of the cover 9 facing the partition 11 and thus also the disk-shaped base body 14, a guide track 26 is formed, which is oriented in a straight line, but running at an angle to a front edge 9d of the cover 9.

On an underside 27 of the base body 14 facing the cover 9, an engagement element 28, which is preferably formed as a pin, is formed eccentrically to the central hole 25. This engagement element 28 engages in this guide track 26 in the assembled final state and thus in the coupled state of the base body 14 with the cover 9.

Due to the eccentric positioning of this engagement element 28 and the specific oblique orientation of the guide track 26, a rotational movement of the base body 14 about the axis A achieves a relative displacement of the cover 9 to the partition 11 and thus a raising or lowering of the cover 9 relative to the partition 11 and thus also reached to drawer 15.

In the exemplary embodiment it is provided that several rotational positions of the base body 14 can be locked and, in particular, locked. In particular, the two possible end positions can be locked here along the actuation path. In addition to these first lockable rotational positions, at least one second rotational position, which is located on the actuation path between these end positions, can also preferably be locked.

To further explain this latching option, the base body 14 will first be explained in more detail. This is in Fig. 6 a view of an upper side 29 is shown, which is thus facing away from the cover 9 and facing the partition wall 11. The disk-shaped base body 14 comprises a jacket wall 30, an indentation 31 being formed by a partial area of this jacket wall 30. In the exemplary embodiment, this indentation 31 is formed as a wedge-shaped cutout. In the assembled final state, the base body 14 is arranged between the partition 11 and the cover 9 in such a way that it is precisely this region of the base body 14 on which this indentation 31 is formed that protrudes forward and overstretched. This enables, on the one hand, an improved actuation of a user who, by inserting a finger into this indentation 31, enables an improved rotary movement which can take place in a non-slip manner.

In this top view, the engagement element 28 is indicated positionally in dashed lines, since it does not extend on this top side 29, but on the underside 27.

In addition, it can be seen that the base body 14 has a guide slot 32, which is curved in the shape of a banana and partially circumferentially around the axis of rotation A. The guide slot 32 is designed to be completely continuous, so that it also represents a slot-like hole lead-through, as it were.

With its total length in the direction of rotation around axis A, the guide slot 32 also defines the maximum mobility of the base body 14 around the axis A. Thus, the guide slot 32 also defines the total length of the actuation path.

In the exemplary embodiment, the guide slot 32 has bulges 36 and 37 directed radially outward at its ends 33 and 34 on a radially outer delimiting contour or edge contour 35. As a result of this configuration, two first rotational positions, which represent the end positions of the base body 14 during the rotational movement about the axis A, are designed as locking rotational positions. The relevant latching is then applied to the Figures 9 to 11 explained. First of all, the base body 14 with its further specifications will be presented. In this context, it is provided that two slot-like recesses 38 and 39 are formed radially outwardly adjoining and adjacent to the guide slot 32, which, viewed in isolation, also have curved, in particular banana-shaped shapes. The recesses 38 and 39 are preferably located on a common radius path, but are separated around the axis A in the direction of rotation. A radial spacer bar 40 is provided for this purpose. It can also be seen that the length of the recess 38 in the circumferential direction about the axis A extends further than the end 34 of the guide slot 32 is formed. This means that, viewed in the radial direction, the end 34 is not located on the same line as an end 41 which faces away from the further recess 38.

In a corresponding embodiment, it is provided that one end 42 of the further recess 39, viewed in the direction of rotation around the axis A, is positioned so as to extend further than the end 33 of the guide slot 32 are not formed on a straight line in the radial direction.

A separating web 43 is formed by the guide slot 32 and in particular the radially outer edge or the outer edge contour 35 and the recesses 38 and 39 that are spaced apart from them, but are adjacent. Due to the corresponding thinness of this separating web 43, which is shape-specific through the continuous recesses 38 and 39 and the continuous guide slot 32 forms, there is also a possibility in which this separating web 43 can be elastically deformed radially outward. This promotes the locking of a specific rotary position.

As shown in Fig. 6 As can be seen, the separating web 43 is formed thinner than at the other points precisely at those points at which the bulges 36 and 37 are formed. The deformability at these points is promoted and the locking of a sliding block 44 external to the control element ( FIGS. 9 to 11 ) is made possible in a particularly simple manner.

As can also be seen, the spacer web 40, viewed in the direction of rotation about the axis A, is arranged approximately in the middle of the total length of the guide slot 32. As a result, on the one hand, a corresponding radial stabilization of the separating web 43 is achieved, and on the other hand, a desired radial mobility of the separating web 43 is achieved precisely at the points at which the bulges 36 and 37 are formed.

How, moreover, in Fig. 6 As can be seen, three movement stabilizing elements 45, 46 and 47 are formed on this upper side 29 of the base body 14, which are also designed as upwardly raised pins. Viewed in the radial direction, they are preferably arranged further outwards than the guide slot 32 and in particular also further outwards than the recesses 38 and 39. In addition, it is also provided that no movement stabilizing element 45 to 47 is arranged in a longitudinal section when viewed in the direction of rotation, in which the guide slot 32 and the recesses 38 and 39 extend.

The rotational movement about the axis A is stabilized by the movement stabilization elements 45 to 47, which engage in at least one stabilization path (not shown) which is formed on the underside 11b of the partition wall 11. An undesired tilting out of the horizontal and / or a displacement in the horizontal direction of the base body 14 is prevented.

In Fig. 7 a view of the underside 27 of the base body 14 is shown. The engagement element 28, which is formed integrally with the base body 14, which is preferably a one-piece plastic part can be seen. It is provided here that elastic deformability in the radial direction is made possible at a front free end 28a of this engagement element 28. In the exemplary embodiment, a plurality, in particular four, elastic pins 28b are formed for this purpose. A hollow cylinder, which then functions as a roller, can be slipped onto this front free end 28a. Such a hollow cylinder 48 is shown in FIG Fig. 8 shown, a view of the underside 27 of the base body 14 being shown there. Such a hollow cylinder 48 functioning as a roller, which is mounted on the engagement element 28 so as to be rotatable relative to the latter, the movement guidance of the engagement element 28 in the guide track 26 can be improved and, in particular, undesirable friction and squeaking noises can be avoided.

In Fig. 9 a view of the underside 11b of the partition wall 11 is shown, the base body 14 being mounted here.

At the in Fig. 9 The illustration shown is the base body 14 in a first end position, which also represents a first rotational position. The sliding block 44 external to the operating element, which is arranged in one piece and in a stationary manner on the underside 11b of the partition wall 11, is locked in the bulge 37. As already explained above, during the rotational movement of the base body 14 about the axis A, which is in Fig. 9 extends perpendicular to the plane of the figure, this sliding block 44 engaging in the guide slot 32 in particular also guided along the separating web 43 and then pushes the separating web 43 radially outward as it approaches the bulge 37, which is made possible by the shape and position of the recess 38. If the bulge 37 is then reached, this sliding block 44, as it were, snaps into the bulge 37 and latches there. As a result of the specification, the deformation and outward pressing of the separating web 43 also enables a radial pretensioning of the sliding block 44, so that the locked position and thus this locked rotational position is also reliably held.

As can be seen, the shape of the bulge 37 is adapted to the shape of the sliding block 44, so that it is precisely arranged therein.

In Fig. 10 is an enlarged detail view of Fig. 9 shown, it can be seen here that the sliding block 44 is locked in this first rotational position, the one forms the first end position along the actuation path and is thus also, as it were, an end stop in the guide slot 32. Starting from this locked rotational position achieved, this locking can then be released by turning the base body 14 counterclockwise and a movement into another locked rotational position can be made possible.

How to do this in Fig. 11 which shows a further enlarged representation of the view in Fig. 10 It can be seen that an embodiment is shown here in which, in addition to the two first lockable rotational positions that define the end positions, a second lockable rotational position that represents an intermediate position between the end positions is made possible. For this purpose, it is provided that the guide slot 32 has, along its entire length between the bulges 36 and 37, a further bulge 49 therebetween, through which a latched rotary position is then formed as an intermediate position. In this intermediate position, the cover 9 is then neither in the completely closed nor in the completely open position.

In addition, further intermediate positions that can be latched can also be formed.
