DEVICE FOR OPENING AND CLOSING STORED COVERS

Description

[0001] The present invention relates to a device for opening and damping a closing movement of mounted, in particular spring-loaded, covers as well as a method for opening and damping the closing of mounted, in particular spring-loaded, covers and a piece of furniture.

[0002] For cabinets, drawers, and other organizational units with a door or other cover, there is a continuing need to provide tools that allow the cover to be easily moved between an open and a closed position.

[0003] Mechanisms by means of which a cover can be moved from a closed position are generally known. Pressure can be exerted on the cover, which activates a mechanism which partially opens the cover towards the person operating it. Particularly with covers without handles, this is a way to safely grasp the cover from above or the side and open it completely. If such a cover is to be closed again, it must be moved completely into a closed position by hand in order to overcome the force of the mechanism by which the cover was at least partially opened. Alternatively, the cover could be slammed shut with sufficient force, but this would cause the cover to hit its frame in the closed or covering position. This can cause damage to the cover, the mechanism and the frame.

[0004] WO 2014 / 117188 A1 teaches a threaded head of a device that interacts with a door. The device can be a damper or an element for opening the door. WO 2014 / 117188 A1 does not teach a combination of the two. In particular, WO 2014 / 117188 A1 does not suggest bringing both devices into operative connection with one another and providing them in a common housing. Rather, based on WO 2014 / 117188 A1, a person skilled in the art would provide the damper and ejection device as two separate devices side by side in order to utilize the advantages of both devices.

[0005] WO 2013 / 134798 discloses an ejection element for a door which operates via a spring mechanism. To prevent the ejection body from hitting the back of its holder hard, a stationary damping body is provided which is intended to dampen the impact of the ejection body when a door is opened forcefully. The damper is not in contact with the ejection body when it is in an extended position. Therefore, the damper according to WO 2013 / 134798 cannot support the damped closing of a door. For this, the damper would have to accompany the door on its closing path, as can be provided according to the present invention. The damping element according to WO 2013 / 134798 is arranged such that it only interacts with the ejection body when the latter is already retracted to an initial position.

[0006] The present invention is therefore based on TaskThe aim of the invention is to provide a device and a method by means of which a cover can be at least partially opened and a closing movement of the same can be at least partially controlled.

[0007] The object is achieved according to the invention by a device according to claim 1 and a method according to claim 3 and a piece of furniture according to claim 4.

[0008] Preferred embodiments are specified in the dependent claims.

[0009] The device according to the invention is characterized in that a working body with a longitudinal axis is provided, which is arranged in a housing, wherein the working body is designed to assume three working positions coaxial to the longitudinal axis: By means of a first compressive force on the working body in the axial direction, the working body can be released from a locking connection and, spring-loaded via a spring of the device, can be displaced from the housing into a first working position against the first direction of the compressive force. By means of a renewed compressive force in the same axial direction, the working body can be partially returned to a second working position in the housing, wherein the working body can be locked to the locking connection and by further sustained compressive force in the same direction, the working body can be returned to an initial position in the housing against the resistance of a damping element.

[0010] The working body and damper are provided in a common housing.

[0011] A locking bracket on the working body can engage in the locking connection and holds the working body back when it engages in the locking connection.

[0012] The locking connection is arranged on the damping element, which is damped relative to the housing and is spring-loaded via a spring of the damping element to load the damping element.

[0013] The damping element has a piston (42) and a damping housing (43).

[0014] The piston is fixed to the housing and the damping housing is damped movable in the housing, wherein in a rear region of the housing, the damping element is provided, which has the spring and damper components,

[0015] The damper housing has a stop in its interior against which the spring is supported, whereby the damper housing can be variably mounted in its position within the housing against the spring pressure of the spring and the spring of the device is arranged coaxially to the damper, which interacts with the working body

[0016] This ensures easy interchangeability of the device, for example, when integrated into a furniture wall. In particular, this eliminates the need for special fixations for the device according to the invention for stationary provision of the same, for example, in a recess in a wall. The housing remains fixed in the preferably precisely fitting recess without displacement, since no forces act on the housing of the device that could force it out of the recess.

[0017] The housing can be cylindrical, cuboid, or have another shape, with one side of the housing being open to allow the working body to exit. The housing can, in particular, be shaped like a small tube, in which the devices according to the invention can be compactly arranged.

[0018] This allows the device to be installed even in the smallest recesses or holes in side panels or in hard-to-reach areas of doors or drawers. A further advantage is its easy interchangeability, since the device according to the invention can be installed in said recesses, holes, or similar without any additional structural measures and can therefore be easily removed by pulling it out and replaced with a spare part without the need for tools. The housing does not necessarily have to have closed outer surfaces, as long as the devices, in particular the damping unit and ejection device, are securely mounted and guided in their position and movement relative to the housing.

[0019] A connecting bracket between and / or around the devices, which ensures sufficient positional stability of the device, in particular in the recess, can also be a housing.

[0020] Preferably, the damper and ejection device contact each other at least in the starting position and an extended position of the working body. Particularly preferably, the damper and ejection device, which may comprise the working body, are in contact and / or operatively connected to each other during any movement and in any position of the working body, in particular relative to the housing. The damper and ejection device can preferably be operatively connected. The damper can contact the ejection device, in particular in an extended position of the working body. The ejection device can comprise at least the working body, but can also be designed with a link, hooks and / or at least one of the elements described below that cooperate with the working body.

[0021] According to the invention, the device has at least one device by means of which the cover can be opened, i.e. moved from an initial position, and a second device by means of which a closing movement of the cover can be carried out in a damped manner. At least one working plane can be provided which is operatively connected to the devices and the cover to be opened. The first and the second device can be provided in a common housing. Preferably, the devices are arranged one behind the other or coaxially to one another, at least partially (radially) one inside the other. At least one of the two devices can be supported on a rear end of the housing and preferably anchored to it. Preferably, the two devices are (fixedly) connected to one another. Preferably, the device is also suitable for closing the cover in a damped manner.

[0022] Mounted covers are in particular those covers which release an underlying opening via at least one hinge or a moving element, whereby the cover can be opened both parallel to an opening (e.g. drawer) and at an angle to the opening (e.g. cabinet door).

[0023] For opening, the working body can be movably mounted relative to a locking mechanism and spring-loaded. Applying a pressure force counter to the opening direction of the cover can release the locking mechanism, allowing the spring to relax and the working body to be moved out of the housing under spring tension. Since the working body can be positioned toward the cover or can be operatively connected to it, it can move the cover from a closed position, making the cover accessible to a user and thus ready for opening, particularly manual, movement.

[0024] For closing, the cover can be spring-loaded or have means that generally allow the cover to return to a closed position. However, the return force of the spring or other return means should be smaller than the return force of the spring or energy storage device by which the operating body moves the door from a closed position, in order to enable the cover to be opened by the operating body.

[0025] Typically, the mechanism for returning the cover to a closed position can be activated as soon as a certain, predefined opening angle of the cover relative to its frame, or a closed position, is exceeded. Instead of an opening angle, it can also be a shortened opening distance of the cover from the opening, particularly in the case of drawers.

[0026] This can prevent the cover from undesirably returning to the closed position when it is wide open. It may therefore also be necessary to first bring the cover into a position in which the means for resetting the cover exerts a restoring force on the cover towards the closed position, so that functional interaction of the cover with the device according to the invention is possible. In principle, the means for resetting the cover to a closed position can be dispensed with, since the device according to the invention prevents the cover from unintentionally striking its frame in the closed position when it is forcefully moved towards the closed position. However, the means for resetting the cover are advantageous in order to move the cover into a closed position after the spring force of the working body has been overcome.

[0027] Therefore, it may be necessary to provide a small amount of additional kinetic energy to the cover when closing, in addition to the restoring force provided on the cover by gently pushing it, in order to overcome the force of the spring on the working body and to enable engagement of the working body with the locking mechanism which can retain the working body in a retracted position.

[0028] The (spring) force (restoring force) present on the cover by the means can be sufficient to overcome the resistance of the damping element, namely a second spring which loads the damping element, whereby the cover can be moved into a closed or initial position.

[0029] In principle, the device according to the invention can be provided with at least one of the following features: a housing, which can have at least one opening, a working body as a contact element with the cover, which can be displaced from the opening between a starting position in the region of the opening and a first working position, wherein the working body can be displaced from the housing in the first working position relative to the starting position, a mechanism for opening the cover, in particular with a spring and a locking part, wherein the spring can be secured in a tensioned state, the working body can be released from the locking part by means of a frontal force acting on it, wherein the working body can be moved out of the opening in a spring-relaxed manner, and the working body can be returned to a second working position in a spring-loaded manner towards the housing and secured to the locking part upon renewed frontal force acting on the working body,a fluid chamber of the damper and / or that the piston is displaceable in the fluid chamber, wherein a portion of a force acting through a cover on the working body in its first working position can be compensated by means of the spring element, and wherein the damper can be designed to return the working body, upon sustained force action, from the second working position to its first position by displacing the piston in the fluid chamber, the spring of the mechanism for opening the cover can be supported against an outer side of the fluid chamber, the spring of the mechanism for opening the cover can be supported against the working body and / or that the working body can be displaced by means of the spring, the locking connection can be fixed to an outer side of the fluid chamber, which can face the working body, the fluid chamber can be movable relative to the housing by means of the spring element coaxially to the working body,that the fluid chamber can be arranged fixedly and the piston can be displaceably arranged in the housing and the fluid chamber, wherein the spring of the mechanism for opening the cover can preferably be supported against an outer side of the piston and / or can be displaceably arranged on this, that the locking connection is designed as a link into which the driver can engage in a locking manner.

[0030] It is provided that a locking bracket on the working body can engage in the locking connection and retains the working body when it engages the locking connection. In principle, the working body can be mounted displaceably relative to the locking means, wherein the locking means can be provided to fix the working body when locked with its locking bracket, in particular to the locking means. Preferably, the connection between the locking means and the locking bracket can be released from the locking means by pressure against a spring-relaxing direction of movement of the working body on the locking bracket or the working body. This can be designed in a similar way to an actuating element of a ballpoint pen for extending and retracting the ballpoint pen refill.

[0031] According to a preferred embodiment of the present invention, the locking connection is mounted so that it can be displaced relative to the housing. In principle, the locking connection can be fixed to the damping element. At least a portion of the damping element can, in turn, be mounted so that it can be displaced relative to the housing, which allows the locking connection to be fixed, but the locking connection can be arranged so that it can be actuated relative to the housing.

[0032] According to the invention, it is provided that the locking connection is arranged on the damping element.

[0033] The locking connection is damped relative to the housing and spring-loaded via a spring of the damping element to load the damping element. In principle, the damping element according to the invention can be designed to generate a counterforce proportional to a force acting on the damping element. This means that when a damping element is actuated with gentle pressure, it yields and, upon sudden application, particularly a strong compressive force, provides increased resistance to the applied compressive force. This can go so far that, upon gentle application of a damping element, it can be displaced with almost no resistance, and upon sudden application of a compressive force, its position remains almost unaltered.As a result, the damping element can counteract the momentum of the (spring-loaded) cover when locking between the locking connection and the driver, in particular the locking bracket, thus providing a resistance which can enable locking and at the same time prevent the cover from striking into its closed position, since the cover can be held back beforehand by the damping element.

[0034] When the momentum of the cover has been used up by locking action against the spring tension, the cover can still be spring-loaded, but at least be provided with a restoring force towards its closed position, whereby the damper can be actuated / returned to a rearward position within the housing after locking by the restoring force, preferably gently. The working body can be returnable to an initial or first position, thereby clearing the path for the cover to a closed position. During the (entire) displacement process of the damper, the cover can contact the working body and provide the necessary force to load the damper against a restoring force of a damper spring or another type of damper energy storage device.

[0035] According to the invention, the damping element comprises a piston and a damping housing. The damping housing is operatively connected to the locking connection and can in particular be fastened thereto. The piston is fixed to the housing of the device. The piston is stationary and the damping housing is movable. In this case, the fluid resistance during a relative movement of the housing and piston can cause a damping effect on the mobility / movement of the piston relative to the damping housing. The provided fluid can pass through a narrowed area to an opposite area of ​​the piston. Since this area is smaller than a cross-section of the piston, a delay occurs in the displacement of the piston, wherein the piston movement is preferably coupled to the amount of fluid displaced from one side of the piston to the other side of the piston.The resistance of the damper can also depend on the ratio of the cross-sections of the piston and the constricted area.

[0036] Furthermore, it is provided that the piston is fixed to the housing and that the damping housing is displaceable in the housing with damping. Advantageously, the mechanism for opening the cover and the damping element can be provided in the same housing. An arrangement in which the damper can be provided coaxially behind or at least partially within the mechanism for opening the cover is particularly advantageous, wherein the mechanism for opening the cover can be arranged on the housing via the damping element or can be mounted so that its position can be changed. By changing the position of the movable damping housing of the damping element, the mechanism for opening the cover can be displaced in the housing.In principle, the damping element and the mechanism for opening the cover can also be arranged parallel to one another, wherein each part can have a working body, the working bodies being arranged approximately parallel to one another. In this case, each part can also have its own housing, wherein both the mechanism for opening the cover and the damping element can be fixed to its respective housing. Particularly when the two devices of the device according to the invention are arranged in parallel, it can be necessary to maintain a certain arrangement of the individual devices relative to one another. A relative orientation of the two devices to one another has been found to be particularly advantageous, in which orientation a cover to be closed can already contact the damping element when interacting with the mechanism for opening the cover after it has been locked into the locking connection, but does not yet press the damping element in completely.

[0037] According to a further development of the invention, it is particularly expedient for the working body to be designed in several parts, wherein a part of the working body can be provided in the same or different housings.

[0038] According to a further development of the invention, it is particularly advantageous that at least two parts of the multi-part working body are provided with their respective longitudinal axes parallel to each other.

[0039] It is particularly useful that one of the two parts of the working body can be coupled to the damping element and the other part of the working body can be coupled to the locking connection.

[0040] It can be expediently provided that the part of the working body with the damping element is arranged in front of or behind the part of the working body with the locking connection.

[0041] According to a particularly preferred development of the present invention, the cover is designed with a return element which, when the cover is opened, is provided with a return force acting in a closed position of the cover, in particular is spring-mounted, wherein the spring can be tensioned when the cover is opened and relaxed when the opening is closed. In principle, the proper functioning of the device according to the invention is also ensured when the cover is closed by a corresponding hand swing in order to reload the mechanism for opening the cover with tension for a new actuating spring. In this case, however, the damping element can still be in a deflected position, which is why the working body can still be arranged outside its initial position or closed position in which it is retracted into the housing.A cover could thus be positioned at a small distance from its closed position. Particularly for moving the damper in the device according to the invention into a loaded position, in which the working body is in a starting or initial position, it may be advantageous to provide the cover with at least one element that transfers the cover into its closed position with a restoring force. Possible restoring elements can be designed such that, when the cover is fully opened, they do not exert a force on the cover that would force it back into a closed position.As soon as a defined angle between the cover and the opening to be closed or the cover frame is exceeded, the return element can be activated, exerting a restoring force on the cover, forcing it back into a closed position. This allows the return element to assist the closing process, in particular by pushing the damping element back to its original position while still holding the cover in a fully open position without the need for force. Instead of an opening angle, an opening distance that is exceeded can also activate a device that exerts a restoring force on the cover. This can be particularly useful for drawers.

[0042] In the method according to the invention for opening and damping a closing movement of mounted covers by means of a device according to one of claims 1 or 2, a first compressive force is exerted on a working body having a longitudinal axis in a first axial direction, whereby the working body is released from a locking connection, the working body is displaced from a housing in a spring-loaded manner into a first working position opposite to the first direction of the compressive force after the first compressive force has been removed, whereby a cover operatively connected to the working body is opened, by a renewed compressive force in the first axial direction of the working body, the working body is partially returned to a second working position in the housing,the working body is locked into the locking connection during partial return and by continuing to apply pressure in the same axial direction, the working body is returned to an initial position in the housing against the resistance of a damping element, whereby the cover can be returned to a closed position.

[0043] In principle, the present invention can relate to a cover system with a foldable or sliding cover and a device according to the invention, wherein the cover can be designed with means that can provide a restoring force into a closed position of the cover.

[0044] The present invention also claims a piece of furniture comprising the device according to the invention for opening covers and damping a closing movement when closing the cover. The device can be provided in a wall, in particular a side wall, a floor, or a ceiling of the furniture. Particularly preferably, the device according to the invention is provided in a bore in the wall, in particular countersunk into the wall. This provides for particularly space-saving accommodation of the device.

[0045] The device according to the invention can also be provided as part of a guide, for example for a drawer, in particular be integrated into it.

[0046] Also disclosed is a system for opening and closing a folding or sliding cover of furniture with a device according to the invention for opening and damping a closing movement of the cover, wherein the cover is designed with means that provide a restoring force in a closed position of the cover.

[0047] An advantageous embodiment is explained in more detail below with reference to the accompanying drawings. They show: Fig. 1 is an exploded view of a device according to the invention for opening and closing covers, Fig. 2 is a cross-sectional view of a preferred embodiment of the device according to the invention for opening and closing stored covers, in which the working body is in a starting position in the housing, Fig. 3 is a cross-sectional view of a preferred embodiment of the device according to the invention for opening and closing stored covers, in which the working body is in a first working position outside the housing, Fig. 4 is a cascade of representations which shows the sequence when actuating the device according to the invention according to a preferred embodiment with the working body in its starting position, the first working position and the second working position.

[0048] Figure 1shows an exploded view of the possible components of a preferred embodiment of the device 10 according to the invention for opening and closing covers. In principle, all components of the device 10 according to the invention can be arranged in a (common) housing 20, in particular retracted, which can be referred to as the starting position. The housing 20 can have a cap 21 in a rear region, via which, for example, a fluid chamber can be filled with fluid. In a rear region of the housing 20, i.e. a region facing away from the opening 22, a damping element is provided, which has, for example, a spring 41 and damper components, which in particular comprises a piston 42, which can be supported within the housing against the rear region, which can have the cap 21.

[0049] The damping element comprises the damper housing 43, which has a stop inside it against which the spring 41 is supported. The damper housing 43 can be mounted within the housing 20 in a position that can be adjusted against the spring pressure of the spring 41. The damper housing 43 can, in particular, have a fluidic barrier inside it, through which fluid from the damper is retained to prevent leakage.

[0050] Coaxial with the damper, preferably on an outer circumference of the damper housing 43, a spring 33 is arranged, which interacts with a working body, which can have the following components: a base body 50 with a front region 51 / 52, which can be detachably connected to the base body 50, and a driver 53, which can be detachably locked to a slotted link 32. The slotted link 32 can be arranged on the damper housing 43 on a side facing the working body. When the driver 43 is locked to the slotted link 32, the working body can be fixed relative to the slotted link 32 and preferably thus also relative to the damper housing 43. In this state, the spring 33 can be compressed, as can be seen in particular from Figure 2 emerges.

[0051] Optionally, a rubber buffer 52 can be arranged at a front end of the working body, which provides gentle contact with a cover to be opened or closed.

[0052] Figure 2 shows the device according to the invention in an initial or retracted position of the working body. In this position, the spring 41 of the damper and the spring 33, which rests against the base body 50 of the working body, can be in a tensioned position. The damper spring 41 can be held in this position, for example, by a cover resting on the front region 51 / 52 of the working body. As soon as the cover is manually removed from the working body of the device 10 according to the invention, the spring 41 can relax and the damping element can be moved in the housing 20 in a spring-relaxing manner (41). As a result, the working body can move out of the housing 20 by the stroke of the damping element.

[0053] The spring 33, which can interact with the base body 50 of the working body and, together with the guide 32, can provide a mechanism for opening a cover adjacent to the working body, in particular the contact area 51, 52, can be retained by the driver 53 locking in the guide 32 and secured to the housing 43 of the damper. For this purpose, the guide 32 can be secured to the housing of the damper 43.

[0054] The working body, link 32, and damper housing 43 can therefore form a unit in the locked state of the driver 53 with the link 32, which can be mounted for movement coaxially with the housing 20, in particular by means of the damper spring 41. The link can therefore be movably mounted in the housing and / or connected to the damper.

[0055] By applying a pressure force to the front area 51 / 52 of the working body, the driver 53 is released / unlocked from the slotted guide 32. If the pressure force is subsequently removed from the front area 51 / 52 of the working body, the spring 33 can relax due to a relative movement of the base body 50 of the working body to the damper housing 43 ( Fig. 4 III). If a cover which rests on the working body is removed, the damper spring 41 can also relax, whereby the working body can be moved from the starting position into a first working position ( Figure 3 ).

[0056] Figure 3shows a preferred embodiment of the device 10 according to the invention in a first working position, in which the working body 60 with its base body 50 is extended from the housing 20 into a first working position. The device 10 can assume this position in particular when the connection between the link 32 and the driver 53 is released and a cover to be moved (opened) by the device 10 is removed from the latter. In principle, the device is suitable for providing a certain distance between the cover to be opened and a frame, which distance is provided in particular by the stroke of the working body from the initial position into the first position.

[0057] By reaching behind the cover and opening it further, the cover can be opened completely, for example, at a 90° angle or more to a door frame, whereby the cover is removed from the working body of the device 10. In such a state, no external forces act on the device 10, which is why both the spring 33 of the mechanism for opening the cover and the damper spring 41 can be relaxed, i.e. at least partially discharged, relative to an initial position of the working body. By relaxing the damper spring 41, a relative movement is provided between the piston 42 and the damper housing 43, whereby a chamber 44 is formed in which a fluid, for example a gas or a liquid, in particular a silicone oil substrate, can be provided. This fluid can be in an initial position of the working body according to Figure 2in a region designated by reference numeral 45. Due to the at least partial discharge of the spring 41, the housing of the damper 43 is moved by a stroke within the housing 20, which can approximately correspond to the coaxial length of the fluid chamber 44 in the housing 20.

[0058] The damping effect of the damping device can be provided in particular by the fact that when a force is applied to the working body, which returns the working body into the housing 20, the fluid is displaced from the chamber 44 and into the area 45 according to Figure 2 must be returned. The work required to push the fluid back into area 45 dampens the movement of the working body back to its initial position.

[0059] By moving the working body coaxially into the housing 20, the driver 53 can be brought back into locking connection with the slotted link 32, whereby the spring 33 is tensioned. A precise sequence of opening and closing according to a preferred embodiment is shown in the Figure 4 can be found.

[0060] For example, Fig. 3 As can be seen, the damper and the ejection device can be arranged at least partially coaxially within one another. The ejection device can be formed by the mechanism for opening the cover and / or can be realized by at least one of the following components: working body and / or spring 33 and / or guide 32 and / or base body 50.

[0061] Thus, the working body and / or spring 33 and / or link 32 and / or base body 50 of the ejection device / mechanism for opening the cover can be mounted at least partially radially outside, i.e., above the damper, in particular radially outside a region of the damper, particularly preferably radially outside the damper housing. The damper can thus be at least partially (radially) surrounded and / or (radially) enclosed by the aforementioned elements.

[0062] Figure 4 shows the process of retracting and extending the working body from the housing 20 in 6 steps I to VI in detail.

[0063] I in Figure 4 shows the working body 60 in a starting position within the housing 20.

[0064] By a first pressure coaxial to the alignment of the working body 60 / to the direction of travel of the working body in the housing 20, the latter is easily pushed into the housing 20, whereby the driver 53 is released from the link 32 (II).

[0065] As soon as the driver 53 is released, the spring 33, which was previously spring-loaded between the damper housing 43 and the working body (II), can be released (III). The state of the device 10 according to the invention shown under III corresponds to a snapshot in time, in which a cover to be opened can still rest in a front area of ​​the working body, which is why the damper spring 41 is still retained in a tensioned position.

[0066] In principle, it may be advantageous to use a spring 33 with a higher spring constant than the damper spring as the spring for the cover-opening mechanism. The spring 33 should be able to exert sufficient force to move the cover from a closed position. In doing so, it may be necessary to overcome a restoring force of the cover, which is intended to hold it in a closed position. Therefore, it may also be necessary for the spring 33 to have a higher spring force than the force with which the cover rests on the device according to the invention.

[0067] Spring 41, on the other hand, serves to load the damper and can therefore be designed with a significantly lower spring force. The spring force of the damper can, in particular, be weaker than the restoring force with which a cover is to be held in a closed position. Since the force of the cover on the device 10 according to the invention is greater than the spring force of spring 41, the spring remains in a tensioned state according to III as long as the cover rests on the working body 60.

[0068] IV shows the device according to the invention in a first working position, in which the cover to be opened is removed from the device, i.e., no longer rests on the working body 60. In this first working position, the damper spring 41 is now at least partially relaxed compared to III, namely by the stroke of the piston 42.

[0069] When the working body 60 is retracted into the housing 20, as shown under V, an operative connection between the driver 53 and the link 32 is restored, tensioning the spring 33. This represents the second working position of the working body 60.

[0070] During this process, the damper can already be moved at least partially relative to the housing 20, whereby the fluid chamber 44 already has a reduced volume compared to a first working position, since the housing 43 of the damper has already been partially moved back into its starting position according to I. V shows the device 10 according to the invention / working body 60 in a second working position, in which the cover now rests on the working body due to a restoring force provided on the cover, but is not yet completely in the closed position. Due to the restoring force of the cover, the working body 60 can now be returned to its starting position (IV) in a damped manner, whereby the cover mounted on the device can be gently returned to a closed position.The restoring force applied to the cover can be provided in particular by means on the cover which, for example, cause a spring-loaded return of the cover to a closed position as soon as the cover, relative to a closed position or a frame, allows the cover to be returned to the closed position by means of the spring force alone.
