RELATED APPLICATIONS

This application is a National Phase of PCT Patent Application No. PCT/EP2013/071082 having International filing date of Oct. 9, 2013, which claims the benefit of priority of German Patent Application No. 10 2012 109 609.0 filed on Oct. 10, 2012. The contents of the above applications are all incorporated by reference as if fully set forth herein in their entirety.

FIELD AND BACKGROUND OF THE INVENTION

The invention relates to a device for the acceptance of a camera with the features according to claim1, which can particularly serve as a parking assistance of a vehicle. The device comprises a housing in which the camera can be exchangeably accepted and a gear which serves for moving the camera between a rest position and an operating position. Further the invention comprises also a method for the actuation of the device for the acceptance of a camera according to claim17.

Devices with a camera which serve for the image acquisition of the external area of a vehicle are already known from the state of the art. Such devices comprise a housing in which the camera is moveably accepted between a rest position and an operating position. For example, such cameras can be used in the area of the assisted parking of vehicles. If, for example, the reverse gear of the vehicle is used, the camera moves from the rest position into the operating position wherein the camera extends at least partially out of the housing. Therefore, the area behind the vehicle is visually recognized by the camera and is shown on a display for the driver of the vehicle. When the reverse gear is ended and the driver of the vehicle removes the reverse gear, the camera can be moved back from the operating position into the rest position.

In DE 10 2009 008 281 A1 a device for the acceptance of a camera is disclosed, which is permanently installed in the existing housing. Thereby the disadvantage has occurred that the device can only accept a certain camera, so that the maintenance and the exchange of the camera cannot be ensured. The device further intends a lid element for the protection of the camera and a gear, which comprises an adjusting mechanism for the camera and a further adjusting mechanism for the lid element. The first adjusting mechanism moves the camera between the rest position and the operating position and the second adjusting mechanism moves the lid element between a closing position and an opening position. Thereby the disadvantage has occurred that the lid element proceeds very close to the car body during the movement from the closing position into the opening position and the interspace is very small. Further the device is constructively complicated assembled with multiple components and needs a great construction space.

SUMMARY OF THE INVENTION

The invention therefore has the objection to obtain a simple, cost-efficient and compact device for the acceptance of a camera, which avoids the previously described disadvantages. Particularly, the device should be able to accept different cameras and enable an effective mode of operation of the camera without damaging the car body. Furthermore the devise should comprise an easy construction and be easy to assemble and to activate.

This objection is solved by a device according to the invention with all features of the independent claim1. Likewise for solving the objection a method for the actuation of a device for the acceptance of a camera is intended with the features of claim17. In the dependent device and method claims preferred embodiments of the invention are described. Features which are disclosed with the device according to the invention, thereby although apply for the actuation method according to the invention and vice versa. The method according to the invention from claim17can be realized with the device according to the invention for a camera.

The invention according to the main claim comprises a slide at which a camera can be exchangeably assembled and a housing, in which a slide can be movably accepted in a first guidance between a rest position, in which the camera is inactive, and an operating position, in which images can be actively recorded by the camera. In the rest position of the slide the camera can be turned off or stay turned on, wherein however normally no images should be recorded. By the movement of the slide into the operating position the camera can be moved within the housing in an image acquisition position for the image acquisition or can be backed out of the housing. Further, the invention intends a lid element by which an opening in the housing is closable, through which the camera unit can be directed to the outside. According to the invention the lid element can on the one hand be movably mounted at the slide and on the other hand in a second guidance in the housing. Thereby, the lid element can be moved between a closing position, in which the lid element covers the opening, and an opening position, in which the lid element releases the opening. The invention idea is that a gear drives the slide through an external drive between a rest position and an operating position in a way that the lid element performs at least one first displacement phase and one second displacement phase between the closing position and the opening position. Advantageously, the lid element thereby does not need a specific adjusting mechanism and can be moved partly by the influence of a slide, which is moved by the gear and can partly be moved through the influence of a second guidance between the desired positions. According to the invention it is particularly advantageous that the lid element can perform a two phase displacement. In the first displacement phase, the lid element can initially be moved away from the car body for example linear. In a second displacement phase, the lid element can be moved in a way that the sight for the camera is released towards the outside. Hereby it can be ensured that the lid element initially moves away from the car body before it moves in the opening position in order not to destroy the vehicle.

Advantageously the slide can comprise a housing side assembly opening in order to exchangeably accept the camera. Through the assembly opening the camera can be inserted and removed in a simple manner. According to the invention the assembly opening can be configured for the acceptance of different camera models. Further, the slide can be configured with an acceptance opening extending towards the outside, through which the camera can be directed towards the outside. Through the opening an objective of the camera can visually recognize the external area of the vehicle in an operating position of the slide.

According to the invention the slide can comprise an adapter for the camera. Thus, it can be ensured that different camera models can be received in the slide. The slide can further be configured in a way that the camera is reliably retained in the assembly state by a form and/or force fit. Further, the slide can comprise latching and/or clamping elements, particularly in the assembly opening, which can complementary interact with the holding elements of the camera, so that the camera is securely assembled in the slide. For example, the camera can be retained in the slide by a bayonet catch.

The gear, according to the invention, can comprise a swing element. The gear can thereby be connected to an external drive at the drive side, in order to move the swing element. Thereby the gear can interact with different drives. Advantageously the drive only needs a swing element, in order to move the slide between the rest position and the operating position. The device according to the invention thereby receives a simple composition and can further be easily mounted at different vehicles. It can be further intended that the gear is configured self-inhibiting.

The previously described swing element of the gear can also be assembled at one side of the slide. Advantageously the swing element can be assembled within the housing. Thereby the device comprising the slide, the gear and the lid element and the exchangeable camera form a building set. The building set can according to a preferred advantage be module-wise assembled and removed or exchanged at the vehicle. At the outside the swing element can for example be assembled at a pivot shaft of the external drive via a drive-side cam, which represents the drive shaft of the gear. The pivot shaft or the cam can thereby extend through a corresponding opening in the housing wall. The extension direction of the pivot shaft can define the pivot axis of the swinging arm. Inside, the swing element can, for example with the housing-side cam, engage in a driving guidance at the slide, in order to move the slide. Alternatively it is possibly that the swing element can be assembled outside the housing, so that the device, comprising the slide, the lid element and the exchangeable camera can form a building set. Thereby, the swing element can engage at the slide by a corresponding recess at the housing, in order to move the slide.

According to the invention the drive guidance can be configured arch-like, in order to convert the swinging movement of the swing element into a linear movement of the slide. Thereby, the drive guidance can be configured mainly vertical. Thereby, the construction space of the device can be ideally used and reduced to an advantaged manner. In the rest position of the slide the swing element can engage approximately in the centre of the drive guidance. If the swing element is moved in one direction towards the operating position of the slide by an external drive, the swing element initially slides in a lower position in the drive guidance, while the slide moves away from the rest position. If the swing element is moved further, the swing element can proceed backwards towards the top into the centre of the drive guidance within the drive guidance, while the slide reaches its operating position. In order to move the slide from the operating position back into the rest position the drive can move the swing element in opposing direction. Further the swing element can be moved from the centre of the drive guidance in an upper position without moving the slide during the rest position of the slide, wherein a free-wheeling of the drive occurs. Advantageously, the swing element can in the upper position in the drive guidance be locked in a way, that a movement of the slide in the operating position is prohibited. Hereby, the slide can also be arrested in the rest position. The lid element can thereby not be opened, so that the camera is secured against unauthorized manipulations.

According to the invention the first guidance can be configured as an upper and/or lower guidance rail in the housing in order to stabilize the movement of the slide. Additionally or alternatively the guidance can thereby be configured as a notch at the lateral wall of the housing. Further or exclusively, the guidance can be configured from a particular form of the housing, which is complementary adapted to the form of the slide in a way that the slide can be shift-secure and tilted-secure guided between the rest position and the operating position. The first guidance is particularly configured as a pure linear guide so that the slide is moveable within the housing, comparable to a drawer in a board like subsequently described in the text.

Advantageously the housing can comprise a first housing shell and a second housing shell. According to the invention the slide and the gear and the lid element can be assembled in or at the first housing shell, in order to simplify the assembly of the device. Thereby it is possible that the device, according to the invention, can be inserted into the first housing shell as a building set in order to further simplify the assembly of the device. Subsequently, the second housing shell can be detachably assembled at the first housing shell by a form and/or force fit and via latching or clamping elements. Hereby, it can be achieved that the device is not only easy to mount, but also that the device is easy to remove and to exchange. For reparation and for exchange of the camera only the second housing shell needs to be assembled in order to enable an access to the device or to the camera.

Further it is possible that the first guidance and the second guidance can be performed at the first housing shell and that a complementary first guidance and a complementary second guidance can be assembled at the second housing shell. This can further provide an additional security in order to guide the slide between the rest position and the operating position stably in a way that the slide cannot tilt or lock within the housing.

Advantageously the slide can comprise a first slide element, which can interact with the first guidance in order to guide the slide. The first slide element can be configured in form of a rod, which can permanently reach through two lateral openings in the slide. Thereby the sliding element can engage with one edge in a corresponding first guidance at the first housing shell and particularly with the other edge in a first guidance at the second housing shell. Thus, it can be further intended that the camera is assembled in the assembled state within the slide in front of the sliding element. The sliding element can thereby avoid that the camera can be shifted backwards or can be withdrawn. Alternatively, the first slide element can be configured as two lateral protrusions at the slide which can be guided in a first corresponding guidance and at which the lid element is pivotably mounted. According to the invention the lid element can be mounted pivotably about an axis at the first slide element, which particularly runs through the slide element. It is advantageous that the slide element can thereby at the same time serve for the guidance of the slide and for the pivotably storage of the lid element. Thereby the amount of the necessary components can be reduced and a simple and compact device for the acceptance of a camera can be established.

The first guidance according to the invention can be exclusively configured as a linear guidance, in order to move the slide between the rest position and the operating position. The embodiment of the first guidance is therefore particularly simple. Advantageously, the slide can be guided stably along the first linear guidance. Also the performance and the assembly of the device and the gear according to the invention are thereby additionally simplified.

Advantageously, the lid element can comprise at least a second slide element, which can interact with a second guidance in order to guide or drive the lid element at least from one side. According to the invention, the second guidance can comprise a first section in order to linear move the lid element in the vicinity of the closing position and comprise a second section in order to move the lid element in the vicinity of the opening position. The first section can thereby be configured linear and particularly parallel to the first guidance and the second section can be configured arch-like or linear, mainly vertical to the first guidance. The first linear section of the second guidance can serve for the fact, that the lid element can be moved linear with the slide away from the car body. The second section of the second guidance can be configured in a way and interact with the second slide element in a way, that the lid element can be moved in the opening position not before a movement away from the car body.

The idea of the invention is by a guidance of a lid element implied in the fact, that the lid element can be moved mainly linear in the first displacement phase and in the second displacement phase mainly pivotable. That means, the lid element is at first moved away from the car body, before it can be moved into the opening position. Therewith it is ensured that the lid element always comprises a sufficient distance to the car body, before it can be moved upwards in the opening position. The device according to the invention serves for the fact, that in the closing position the lid element optimally abuts at the opening in the housing and can build a preferably flush level with the car body. The appearance of the vehicle is thereby significantly increased. At the same time the device ensures that in the opening position the lid element can keep a suitable distance to the car body, so that the lid element cannot knock against the same and damage the car body.

The gear according to the invention can advantageously be configured in the way, that the first displacement phase and the second displacement phase are performed sequentially. Alternatively it is however possible that the gear can be configured in a way, that the first and the second displacement phase can at least partially overlapped. The gear is a drive mechanism within the sense of the present invention.

According to the invention a protection membrane can be intended, which can sealingly close the free space between the opening in the housing and the slide in order to avoid the penetration of dirt particles and moisture into the housing and protect the camera from weather influences. The protection membrane can be configured in form of a bellow membrane, particularly tube-like. Thereby one edge of the bellow-like protection membrane can be assembled at an edge of the opening outside at the housing. This edge of the protection membrane can thereby be assembled at the outside at the opening of the housing or can be glued or screwed to the edge of the opening. The second edge of the bellow-like protection membrane can likewise be assembled at an opening at the outside, particularly at the acceptance opening of the slide. This edge of the protection membrane can be kept at the edge of the opening by a clamping ring or a clamping element and/or glued to the edge of the opening. The protection membrane can thereby be configured from elastic material, preferably rubber. During the movement of the slide the protection membrane can be deformed. Advantageously the membrane completely sealingly closes the opening in the housing, so that neither dirt nor moisture can penetrate into the housing and can damage the camera.

Further it can be intended that the opening is be configured with a collar element, particularly in form of a sealing. At the collar element the lid element can noiseless and/or sealing abut or, if necessary, absorb when the slide is in the rest position. Advantageously, the collar element can be configured from elastic material.

The housing of the device and/or the gear and/or the slide and/or the swing element can be configured from any plastic, metal or such like, which particularly comprises a higher hardness than the material of the protection membrane and/or the collar element.

Further, the objection according to the invention is solved by a method for the assembly of the previously described device with all claimed features. The assembly can thereby comprise the following steps: In a first step the gear, the slide and the lid element can be assembled in or at the first housing shell, in the second step, the second housing shell can be detachably assembled with the first housing shell in a way that the lid element can at least perform a first displacement phase and a second displacement phase between a closing position, in which the lid element covers the opening, and an opening position, in which the lid element releases the opening.

Further the objection according to the invention is solved by a method according to claim17for the actuation of the previously described device with all claimed features. The device can thereby comprise a housing in which a slide can be moveably received for an exchangeable assembly of a camera and a lid element for closing an opening in the housing through which the camera can be directed towards the outside. The invention thereby intends that the slide can be linear moved from a rest position in which the camera is inactive and an operating position in which images are actively recorded by the camera. Thereby, the lid element can be partly linear and partly pivotably moved from a closing position, in which the lid element covers the opening, in an opening position, in which the lid element releases the opening. That means that the lid element is at firstly linear reversing out of the housing in order to achieve a sufficient distance to the car body and subsequently can only be moved in the opening position when enough space is available for a swinging movement.

In the figures identical reference signs are used for the same technical features also in different embodiments.

FIG. 1shows a device100according to the invention in an exploding view, which comprises a slide20, at which a camera50can be exchangeably assembled. Further, the device100intends a housing10in which the slide20is moveably received in a first guidance11a,11b,15a,15b,17between a rest position A, in which the camera50is inactive, and an operating position B, in which images can be actively recorded by the camera50. TheFIGS. 2b, 3aand 4ashow the slide20in more detail in the rest position A, wherein theFIGS. 2c, 3b, and 4cshow the slide20in the operating position B.

With the device100a lid element40is intended which can close an opening16in a housing10, through which the camera50can extend towards the outside, like it can be recognized inFIGS. 2c, 3band 4c. The lid element40comprises thereby a first leg40aand a second leg40b, which are configured arch-like and at least laterally enclose the slide20in the assembled state. The legs40a,40bcan be stored at the slide20in a way that the lid element40can be moved about an axis22. Hereby, the legs40a,40beach comprise an opening41a,41b, through which a slide element21can reach through, which is configured by the swinging axis22for the lid element40. The axis22with the slide element21can thereby likewise be guided through two openings in the slide20, so that the lid element40can be moved regarding the slide20. The axis22with the slide element21are guided through the corresponding opening in the slide20in a way, that they extent behind the camera40in the assembled state, in order to reversely secure the camera50against a drop out. Further, the legs40a,40bare provided each which a second slide element42a,42b, which are kept in a second guidance12a,12bin the housing10. According to the invention the lid element40can be moved between a closing position C, in which the lid element40covers the opening16and an opening position D, in which the lid element40releases the opening16. The closing position C of a lid element40is clearly shown inFIGS. 2a, 2b, 3aand 4a. The opening position D of a lid element40is further shown inFIGS. 2c, 3band 4c. According to the invention a movement of the slide20effects a rest position A and an operating position B a movement of the lid element40between the closing position C and the opening position D.

The slide20is according to the invention configured with a housing side assembly opening24, in order to exchangeably accept the camera50. In the assembly opening24different cameras50can be accepted. Further, the slide20comprises an acceptance opening25, directing towards the outside. Through the acceptance opening25and through the opening16in the housing10an objective of a camera50can visually record the external area of the vehicle in the operating position B of the slide20. The slide20thereby comprises an adapter26for the camera50in order to ensure that different camera models can be received securely and attached in the slide20. The adapter26can be configured as a special form at the inner wall26of the slide20in order to reliably keep the camera50in the assembled state by a form and/or force fit. Alternatively or additionally the slide20can comprise latching and/or clamping elements as an adapter26, which can for example be configured in the assembly opening24. The latching and/or clamping elements can thereby interact with complementary holding elements at the camera50in order to establish a form and/or a force fit. TheFIGS. 3aand 3bshow the slide20according to the invention from the side of the assembly opening24, wherein at the inner wall26of the slide20the adapter26can be configured for keeping the camera50.

Like it can further be recognized inFIG. 1the gear30comprises a swing element31particularly lever-like, which can be moveably, particularly pivotably, assembled between the slide20and a housing shell10b, at a driver side cam32(drive shaft). Thereby the drive side cam32engages in an opening in the housing shell10band can be torque proof assembled at a pivot shaft of a not shown external drive and build a pivot axis for the swing element31. The drive can twist the cam32and thereby move the swing element31. At the side of the slide20the swing element31comprises a housing side cam33, which can interact with the drive guidance23of the slide20, in order to move the slide20and thereby the lid element40.

The drive guidance23, which is further shown inFIGS. 4ato 4cis configured arch-like and extends mainly vertically and perpendicularly to the first guidance11a,11b,15a,15b. The embodiment of the drive guidance23serves on the one hand for the optimal utilization of the construction space of the device according to the invention. On the other hand it is the function of the drive guidance23to convert a swinging movement of the swing element31in a linear movement I of the slide20, like shown in detail inFIGS. 4ato 4band subsequently described in detail.

The housing10according to the invention comprises a first housing shell10aand a second housing shell10b. Like shown inFIG. 1, the slide20and the gear30and the legs40aand40bof the lid element40can be assembled in or at the first housing shell10a. The mounting of the device100is herewith advantageously simplified. After the assembly of the component elements20,30and40in the first housing shell10a, subsequently the second housing shell10bcan be assembled at the first housing shell10a. Hereby, a form and/or force fitting connection is possible optionally with additional latching or clamping elements. The second housing shell10bis removable on purpose of an exchange of component elements at all times, particularly the camera50.

The first assembly step of the device according toFIG. 1can be described according toFIGS. 3a, 3b. Thereby, the camera50can be inserted in the assembly opening22or in the acceptance opening25of the slide20. The composed camera50with the slide20can in the second mounting step be inserted into the housing shell10a, like shown inFIGS. 2b, 2c. On the slide20the lid element40can be put on top, which can laterally enclose a slide20with the legs40aand40b, like shown inFIGS. 3aand 3b. TherebyFIGS. 3aand 3bshow the device100from a point of view from the side of the assembly opening24of the slide20without housing shells10a,10b.

The second mounting step can be described according toFIGS. 2band 2c. The camera50assembled with the slide20can now be inserted in the first housing shell10a. Subsequently, the lid element40can be put on in the first housing shell10aat the slide20from the outside through the opening16, until the legs40a,40benclose the slide20at both sides. The lid element40is positioned in a way that the acceptance opening41a,41bfor the slide element20in the legs40a,40bof the lid element40and the acceptance opening in the slide20are lying on top of each other. Further, the slide element21and the axis22can be guided through the opening41a,41buntil the left edge of the first slide element21extends in the first guidance11aand the second slide element42aof the leg40aextends in the second guidance12a, wherein the guidances11a,12aare explicitly shown inFIG. 1. Therewith the swinging connection between the slide20and the lid element40and an operative connection between the second guidance12aof the housing shell10aand the slide element42acan be performed. In the following mounting step, the swing element31can be assembled in the drive guidance23of the slide20via a housing side cam33. InFIG. 2b, the device100according to the invention is shown in the rest position A of the slide20and inFIG. 2cthe device100is shown in the operating position B of the slide20.

In a final mounting step, the second housing shell10bcan be put on the first housing shell10ain way that the right edge of the first slide element21can engage in the first guidance11b, the second slide element42bof the leg40bcan engage in the second guidance12band the drive side cam32of the swing element31can engage in a corresponding opening of the second housing shell10b, like subsequently likewise shown inFIGS. 4ato4c.

FIG. 2ashows a device100according to the invention according toFIG. 1in an assembled state, which comprises the form of a building set, which can be module-like assembled at the vehicle. The building set is thereby configured from a first10aand a second housing shell10band covered by the lid element40from the front. The second housing shell10bcomprises at the inner side a first11a,11band a second guidance12a,12b, via which the gear30with the slide20and the camera50and the legs40a,40bof the lid element40are movably mounted in the housing10. The gear side cam32of the swing element31, not shown inFIG. 2a, can now be connected to an external drive and the device can be turned in the operating state.

FIGS. 4ato 4cfurther show a first11a,11band a second guidance12a,12b, according to the invention, which each are formed at the first10aand the second housing shell10b. Thereby in the first housing shell10aan upper guidance rail15band a lower guidance rail15aare intended, which engage in two corresponding recesses at the edge27of the slide20, in order to guide and stabilise the movement of the slide20within the housing10. Additionally it can be intended, that the interior17of the housing10is configured in a way that it can build a first guidance17for the slide20with the edge27of the slide20. Thereby, it can be avoided that the slide20is tilted or clamped in the housing shell10a.

The first guidance11a,11b,12a,12b17according to the invention is only performed as a linear guidance in order to linear move the slide20between the rest position A and the operating position B, like shown inFIGS. 4ato 4c. Hereby, an edge of the slide element21engages in the first guidance11a,11b. The lid element40again comprises a second slide element42a,42b, which is guided in a second guidance12a,12b, in order to transfer the lid element40from the closing position C into the opening position D. Additionally, the lid element40is moved at the axis22, which runs through the slide element21. According to the invention the second guidance12a,12bcomprises a first section13a,13b, which runs parallel through the first guidance11a,11b. Via the first section13a,13bthe lid element40is almost linear moved in the vicinity of the closing position C like indicated by the arrow I. The first linear section13a,13bof the second guidance12a,12bserves according to the invention for the fact, that the lid element40is with the slide20moved away from the car body. The linear movement of the lid element40determines a first displacement phase I. Further the second guidance12a,12bcomprises a second section14a,14b, which extends vertically to the first section13a,13b. The second section14a,14beffects that the lid element40is moved in the vicinity of the opening position D. The second section14a,14bcan be alternatively formed arch-like. The second section14a,14bof the second guidance12a,12beffects in a way with the second slide element42a,42btogether, that the lid element40can only perform a second displacement phase II after a first displacement phase I. Herewith the lid element40can be moved in the opening position D ofFIG. 4caccording to the slide20, while the slide20is moved further in the direction of the arrow I in the operating position.

In the rest position A of the slide20(FIG. 4a) the housing side cam33of the swing element31engages in the centre of the drive guidance23. When the swing element31is moved by an external drive in the direction of the arrow II the housing side cam32slides at first downwards in the drive guidance23. The slide20is thereby driven to the right from the rest position A into the position of theFIG. 4band the direction of the arrow I. Afterwards, the swing element31is further moved in the direction II. Thereby the housing side cam33slides back to the top in the drive guidance23until approximately in the centre of the drive guidance23. At the same time the slide20moves further in the direction I to its operating position B ofFIG. 4c. Back in the rest position A the slide20can be moved when the swing element31is moved in the opposing direction of the arrow II. According to the invention the cam33can be moved from the position ofFIG. 4aupwards in the drive guidance23and locked there without moving the slide20in order to arrest the slide20in the rest position A. The lid element40can thereby not be opened wherein the camera50is protected against manipulations. Hereby a free wheel for the drive is created, so that the gear30is self-inhibiting and a mechanic tension is avoided.

Thereby the gear30can drive the slide20through an external drive between the rest position A ofFIG. 4aand the operating position B ofFIG. 4c, wherein the lid element40can perform the first displacement phase I and the second displacement phase II between the closing position C and the opening position D, like shown inFIGS. 4ato 4c. The lid element40is according to the invention linear driven through a housing side cam33by the slide20on the one hand and on the other hand through the influence of the second section14a,14bof the second guidance12a,12b, moved in the opening position D about the cam33, in which position the sight for the camera50towards the outside is free. According to the invention it is essential that the lid element40at first linear moves away from the car body before it is moved in the opening position D, in order not to abut to the car body. Whereas in the closing position C the lid element40abuts almost flush at the car body. The first displacement phase I and the second displacement phase II can only be performed sequentially or can partly overlap.

According to the invention further a protection membrane can be intended, not shown inFIGS. 1 to 4c, in order to seal the free space between the opening16in the housing10and the slide20. The protection membrane can advantageously avoid the penetration of dirt particles and moisture into the housing10and protect the camera50from weather influences. The protection membrane can be configured as a bellow membrane and be assembled outside at the housing10. The protection membrane can be configured from elastic material, wherein during the movement of the slide20the protection membrane9can be deformed.

Further it can be intended that the opening16is configured with a collar element18, particularly in form of a sealing from an elastic material, at which the lid element40can absorb, in order to avoid closing noises, when the slide20moves back to the rest position A. The collar element18can further act sealingly.

The housing10of the device and/or the gear30and/or the slide20and/or the swing element31can for example be configured from plastic and be performed by a forming process like casting or injection molding. The housing10and the gear30including the swing element31can be performed from a first material and the protection membrane and the collar element18from a second material, wherein the first material comprises a higher hardness than the second material.

All features and all advantages from the claims, the description and the drawings including constructive details and special assemblies can each single for themselves or in different combinations be essential for the invention particularly based onFIGS. 1 to 4c.
