Description

[0001] The present invention relates to a furniture fitting for moving a furniture element movably arranged on a furniture body, and to a piece of furniture comprising a furniture body and at least one furniture fitting.

[0002] A furniture fitting serves to connect a furniture's main body, such as a cabinet or housing, to a movable furniture element. Movable furniture elements include, for example, doors or lids. The furniture element can move between a closed and an open position, and for added convenience, the opening and closing of the furniture element can be dampened.

[0003] A variety of furniture fittings are already known from the prior art, which typically connect a furniture carcass and a movable furniture element. The furniture carcass is, for example, designed as a cabinet housing and the movable furniture element as an upward-opening lid, the lid being connected to the cabinet housing via at least one furniture fitting so that the lid can be opened and closed.

[0004] Such a furniture fitting is known, for example, from DE 102 23 026 B3. In this fitting, an adjusting slide is linearly displaceable within a housing. The adjusting slide has a roller that is rotatably mounted on the sliding slide. The roller is subjected to force in contact with an adjusting contour of the adjusting arm. Compression springs are used for this purpose, which actuate the adjusting slide and thus the roller against the adjusting contour.

[0005] Furthermore, known furniture fittings can incorporate a damping device that reduces the force exerted on the lid during opening or closing. This allows the lid to move smoothly into the open or closed position. However, it may also be desirable for a furniture fitting to temporarily disable the damping function in certain applications or installation situations. This is achieved through a switchable damping mechanism.

[0006] A furniture fitting with a switchable damping function is known, for example, from EP 2 949 852 A1. In this fitting, a switching device for deactivating the damping function is designed such that a movable damper element, which primarily absorbs the forces of the closing lid, can be held in a detent position. By holding the originally movable damper element in a detent position, it is fixed and is no longer able to absorb forces. The damping function is thus deactivated. The movable damper element is held in place by a lever element, which engages a section of the movable damper element via a lever arm. The movable damper element is thus positively prevented from moving and therefore from exercising its damping function.

[0007] The furniture fittings known from the prior art have the problem that their damping device can either not be switched on or off at all, or only with increased effort.

[0008] It is therefore the object of the present invention to provide a furniture fitting as described in the introduction, wherein the damping function can be switched on or off in a particularly simple manner.

[0009] To solve the problem, a furniture fitting for moving a furniture element movably arranged on a furniture carcass is proposed, comprising a base element; an articulated arm arrangement with at least one articulated arm for adjusting the movable furniture element, wherein the articulated arm arrangement is adjustably arranged on the base element;A damping device comprising a movable damping element and a damping element fixed to the base element, wherein the movable damping element is operatively connected to the articulated arm over at least part of a pivot path and at least partially counteracts a force transmitted to the articulated arm assembly, and a switching element arranged on the damping device which can be switched between a release position releasing the damping device and a blocking position blocking the damping device, wherein a blocking section is arranged on the switching element which can be positioned in a force-locking blocking manner against the movable damping element in the blocking position.

[0010] The furniture fitting according to the invention offers the advantage of being able to switch the damping device on and off in a particularly simple manner, thus enabling the furniture to be used with or without a damping function. The simple switching on and off of the damping function is particularly advantageous for the use of the furniture fitting according to the invention with an electric motor, since, depending on the application, damping or a slow approach to an end position can be implemented via the control system when using an electric motor.

[0011] The basic element can be the furniture carcass itself, which is designed, for example, as a cabinet carcass, or a component arranged in or on the furniture carcass to which the furniture fitting according to the invention is connected. The furniture fitting can, of course, also be arranged on an alternative piece of furniture that has a hinged element and is therefore versatile in its application.

[0012] The articulated arm assembly comprises at least one articulated arm for adjusting the movable furniture element. The articulated arm assembly pivots about at least one axis of rotation, so that sections of the articulated arm assembly and / or sections of the articulated arm travel a pivot path during an opening or closing process. The articulated arm assembly is adjustably mounted on the base element, allowing different positions of the movable furniture element to be achieved. Depending on the complexity of the furniture fitting according to the invention, further articulated arm assemblies and / or additional articulated arms can, of course, be provided to execute more complex movements of the movable furniture element.

[0013] The damping device can, in particular, include a separate damper arranged on the base element, which, for example, is designed as a fluid damper such as an air or oil damper. The damping device comprises a movable damping element and a damping element fixed to the base component, wherein the movable damping element is adjustable between a damping start position and a damping end position relative to the fixed damping element. The fixed damping element can be designed as a piston rod and, like the damper bracket, be fixedly arranged on the base element. The piston rod can be supported against the damper bracket or fixed to it. The damper bracket can be made of a plastic or metallic material and have a recess. However, it can also be provided that the damper bracket is only partially formed and in the shape of a longitudinally cut cylinder.According to this design, the damper bracket, which is then designed as a half-cylinder, at least partially encloses the movable and the fixed damper element on the side facing away from the blocking section.

[0014] The movable damping element is preferably arranged within the damping bracket, the damping bracket having at least one recess through which the locking section of the switching element can contact the movable damping element. The switching element can have the locking section and a main section, the locking section being understood as either a partially separate section or an integral section of the main section.

[0015] By contacting the locking section, it is positively locked against the movable damper element. The damper, as part of the furniture fitting, serves to dampen or decelerate the movement of the movable furniture element when it reaches a closed and / or open position. This prevents unwanted impact noises and / or damage to the furniture or the movable furniture element. The intensity of the damping effect, or in other words, the force that counteracts the force transmitted to the articulated arm assembly, can be influenced not only by the type of damper but also by its position on the articulated arm.

[0016] It may also be provided that additional damping devices are arranged on the swivel arm and / or on further swivel arms and / or on further articulated arm arrangements.

[0017] The switching element can be operated manually, if necessary with a tool, for user convenience. In the release position, the locking section on the switching element essentially does not contact the movable damping element, allowing the damping device to function without restriction. However, when the switching element is in the locking position, the locking section of the switching element, at least when the movable damping element is retracted, contacts the movable damping element through the recess in the damping bracket, thus blocking any movement of the movable damping element when it is in its end position. In the locking position, the damping device is therefore inactive and thus deactivated.

[0018] The switching element can be moved from a release position (enabling the damper) to a blocking position (blocking the damper), and vice versa. If the switching element is moved from a release position to a blocking position while the movable damper element is still in its damping start position, the damper remains active initially. After the switching element moves to the blocking position, in which the blocking section of the switching element enters the travel range of the movable damper element, the damper can dampen exactly one last time. Only after this final damping action is the movable damper element positively locked into position by the blocking section of the switching element.Subsequently, the damping device is permanently deactivated in the blocking position and therefore no longer dampens until the switching element is switched from the blocking position back to the release position.

[0019] The contact between the switching element and the movable damper element is made via the blocking section located on the switching element. In the blocking position, the blocking section can be positioned against the movable damper element in a force-fit manner. By force-fit positioning of the blocking section of the switching element, the intensity of the blocking effect on the movable damper element can be gradually adjusted. In other words, the stronger the force fit, the more secure the blocking. The blocking section can be designed either as an integral part of the switching element or as a separate component.

[0020] In summary, the furniture fitting according to the invention advantageously allows a damping effect to be selectively switched on or off, so that the furniture fitting is suitable for furniture with and without a damping function.

[0021] Preferably, the switching element is rotatably arranged on the damper device between the release and locking positions about a rotational axis. This rotatable arrangement can, for example, be located in a bearing recess of the base element or the furniture fitting housing, ensuring that the rotation of the switching element between the release and locking positions is relatively backlash-free and low-wear. Alternatively, the rotational axis can be formed by a retaining element. This retaining element can be, for example, a pin or a cylinder or hollow cylinder designed as a shaft, around which the switching element can rotate. The rotatable arrangement of the switching element on the damper device results in a particularly compact assembly, thus advantageously minimizing the space required for the furniture fitting. Furthermore, the rotation of the switching element facilitates the positive locking against the movable damper element.To lock the damper mechanism, the user simply rotates the switching element around its axis of rotation. In other words, the damper mechanism is locked by clamping. This offers the advantage of preventing individual components or sections from jamming or jamming, as often occurs with positive-locking switching mechanisms.

[0022] Preferably, the blocking section is elastically adjustable or deformable on the switching element. For example, the blocking section can be designed as a separate element and made of a different material than that of the switching element. The part of the switching element not designated as the blocking section is referred to as the main section. According to this embodiment, the different material-related elastic deformation properties of the blocking section and the main section result in a switching element with a comparatively enhanced ability to provide a force-fit blocking connection. However, the blocking section and the main section of the switching element can also be made of the same material.

[0023] For example, the switching element can be designed in the shape of a "6", with the blocking section forming the upper, open area and the main section the lower, circular area of ​​the six. Alternatively, the switching element can also be designed in the shape of an "8", with the blocking section being oval and forming the upper part of the eight, and the main section forming the lower part of the eight. Of course, the switching element is not limited to these designs and can also have other shapes.

[0024] The blocking section can also be designed as a cantilever arm that is connected to the main section only at one end. This embodiment of the switching element is similar to the embodiment in which the switching element is designed as a "6". The end of the cantilever arm that is not connected to the main section is referred to as the free end. Since the blocking section and the main section are connected to each other at one end of the cantilever arm, they form a single component according to this embodiment.

[0025] When the switching element is rotated from the release position to the blocking position, the free end of the cantilever arm contacts the movable damping element. If the switching element is rotated further after initial contact, the pressure between the cantilevered blocking section and the movable damping element increases, simultaneously bringing a larger area of ​​the blocking section into contact with the movable damping element. The force acting on the frictional connection is thus increased by the continued rotation, effectively blocking the damping device. The elastically adjustable or deformable arrangement of the blocking section on the switching element allows for particularly easy activation and deactivation of the damping device.

[0026] Preferably, the blocking section is designed as a pivot arm. In this embodiment, the end of the blocking section, which is rigidly connected to the switching element or to the main section of the switching element, can be arranged on the switching element by means of a joint or a hinge, so that the pivot arm is pivotable.

[0027] When the movable damping element is in its damping end position, the free end of the swivel arm, during a switching process from the release to the locking position, first comes into contact with the movable damping element to form the positive connection. A force storage device, such as a spring, can be arranged on the side opposite the joint to apply a compressive force.

[0028] The energy storage device pre-tensions the swivel arm and positions it in a force-locking manner against the movable damper element. The energy storage device can support a force resulting from elastic deformation in the area of ​​the fixed end of the swivel arm.

[0029] The locking section preferably features a film hinge. The film hinge is arranged at the fixed end of the locking section, which is designed as a pivot arm, and can perform a hinge or folding movement. The film hinge thus connects the locking section and the main section of the switching element. Using a film hinge on the locking section results in a hinge that is easy to manufacture.

[0030] A spring element can be pre-tensioned between the blocking section and the switching element to act as a force storage device. In this context, the spring element can, for example, be a coil spring. This embodiment of the switching element is particularly advantageous if the blocking section is designed, for example, as a pivot arm.

[0031] Preferably, the switching element has a circumferential contour that is spaced apart from the movable damping element in the release position and can be positioned in contact with the movable damping element in the blocking position. When the movable damping element is in its damping end position, the circumferential contour is spaced apart from the movable damping element in the release position of the switching element, whereby the damping device is activated and can dampen without restriction.

[0032] Furthermore, the spacing provides a certain tolerance, preventing unintentional activation of the switching element and thus preventing an unintended shutdown of the damping device, even during relatively intensive damping activities. The switching element's circumferential contour can also be designed with different surface textures, such as bumps or grooves, making it particularly easy for the user to identify by touch. This circumferential contour thus makes the switching element especially easy to operate.

[0033] Preferably, the locking section of the switching element has a circumferential surface with a contour that deviates from a circle, wherein the locking section can be contacted with the movable damping element via the circumferential surface. For example, the circumferential surface can be elliptical with a non-constant radius. The non-circular contour allows the intensity of the force-locking positioning in the locking position to be adjusted particularly advantageously by the user.

[0034] For example, the circumferential surface may have one or more recesses to create a detent effect. In this design, corresponding protrusions can be provided on the movable damping element to reinforce the detent effect. In the locked position, the force-fit positioning of the movable damping element can then occur incrementally. The user thus receives feedback indicating the degree to which the locking section has already moved into the locked position.

[0035] It is also possible for the circumferential surface to have different surface textures, for example in the form of bumps or grooves, so that the locking position can be adjusted particularly gently. The circumferential surface and / or the surface textures and / or the bumps and / or the grooves can be made of a relatively soft material such as rubber.

[0036] Preferably, the circumferential surface of the blocking section has a varying distance from the axis of rotation in the circumferential direction. This varying distance from the axis of rotation can be achieved, for example, by a curved surface of the blocking section. The blocking section can thus be arranged in the blocking position particularly easily, making the switching element correspondingly easy to operate.

[0037] Preferably, the furniture fitting has a main force storage element that is coupled to the articulated arm assembly in such a way that the latter is subjected to a force over at least part of a pivoting path towards at least one end position. The end position can, for example, be the position of the movable furniture element in the closed or open position. The main force storage element can, for example, be designed as a spring element through which a force acts on the articulated arm assembly, particularly when a user opens or closes the movable furniture element.

[0038] The main power storage system prevents the user from moving the entire mass of the movable furniture element using muscle power alone; instead, it provides support. It can also be designed so that the force is only applied to the articulated arm assembly for a limited time during the opening or closing motion. In this case, the user only needs to exert a comparatively small amount of force to move the furniture element to its respective end position. The main power storage system thus enables particularly easy opening and closing of the furniture.

[0039] Preferably, the main force storage element is designed as a flat spring. The flat spring design makes the main force storage element, and thus the furniture fitting, particularly space-saving. The flat spring can be made of a metallic material such as a steel or copper alloy.

[0040] Preferably, the main energy storage device has a first spring arm and a second spring arm, with the first spring arm being rigidly mounted to the base element. This design and integration of the main energy storage device results in a particularly compact design for the furniture fitting.

[0041] Preferably, the furniture fitting includes a pressure device coupled to the articulated arm assembly in such a way that the latter is subjected to a pressure force over at least part of its pivoting path towards at least one end position. The pressure device can, for example, be an additional coil spring or a further damping device and can counteract the force of the damping device and, if applicable, the force of the main energy storage device on the articulated arm assembly. To make the interaction between the pressure device and the articulated arm assembly comparatively free of play, the pressure device can have a pressure device head. The resulting forces acting on the furniture fitting are reduced by the pressure device, and only a comparatively reduced force acts on the movable furniture element. Thus, the furniture fitting is particularly suitable for opening and closing lightweight lids.

[0042] The pressure device can also be guided on the furniture fitting via a guide device, allowing it to be positioned at different locations. This enables the pressure device to contact the articulated arm assembly at different points and counteract the forces of the articulated arm assembly at correspondingly different positions.

[0043] Preferably, the articulated arm assembly includes a functional articulated arm for additional functions, such as damping the furniture fitting, with a pressure contact section. The functional articulated arm is pivotally adjustable on the base element, and the pressure device acts in the area of ​​the pressure contact section with the functional articulated arm of the articulated arm assembly.

[0044] The pressure contact section can be designed to have an actuating contour by means of which the pressure device contacts the functional articulated arm particularly advantageously via a pressure device head. The actuating contour can, for example, have a circular path so that the pressure device, during the movement of the lid into an end position, contacts the also moving functional articulated arm along this circular path. The shape of the actuating contour thus influences the direction in which the acting forces are transmitted and therefore the effect of the pressure device.

[0045] In particular, it can be provided that the positioning contour additionally has at least one detent section, so that the movable furniture element is guided into a detent position near an end position. The detent section gives the furniture fitting according to the invention a snap-fit ​​function. Depending on the position of the detent section on the positioning contour, the snap-fit ​​function of the furniture fitting can be activated in an end position corresponding to either an open or a closed position.

[0046] Preferably, the movable damping element is designed as a cylinder and the fixed damping element as a piston rod connected to a piston guided within the cylinder. The piston rod is fixed to the damper bracket of a damping device or axially supported against it. The described assembly requires comparatively little space, so the damping device and thus the furniture fitting are advantageously designed to be space-saving. The damping device can, for example, be designed as a fluid damper. The damping device can be adapted to the needs of the user or to a specific application of the furniture, so that the furniture fitting is flexible in its use.

[0047] According to a further aspect, the invention relates to a piece of furniture comprising a furniture body and at least one furniture fitting for moving at least one furniture element movably arranged on the furniture body. The furniture body can, for example, be a housing, a frame, or an outer wall of a piece of furniture, wherein the movable furniture element can be designed as a lid, a cabinet door, or a cover. The furniture fitting according to the invention allows the movable furniture element to be moved by a user in a particularly simple manner, and the furniture according to the invention can be opened and closed accordingly with ease. Furthermore, the furniture according to the invention can be particularly advantageously adapted to different uses by simply switching the damper device on and off.

[0048] The invention will be explained in more detail below with reference to the following figures.

[0049] They show: Fig. 1a a schematic representation of an embodiment of the furniture fitting according to the invention, Fig. 1b a schematic representation of the interaction of the pressure device with the articulated arm arrangement, Fig. 2 a schematic representation of the activated damper device and the switching element in a release position, Fig. 3 a schematic representation of the actively damping damping device and the switching element in a release position, Fig. 4 a schematic representation of the deactivated damper device and the switching element in a blocking position and Fig. 5 A schematic representation of the deactivated damper device and the switching element in a blocking position.

[0050] Fig. Figure 1a shows a schematic representation of an embodiment of the furniture fitting 1 according to the invention, comprising a base element 10, an articulated arm assembly 20 with an articulated arm 21 for adjusting a movable furniture element 100 designed as a lid, a functional articulated arm 22, a damper device 30, and a switching element 40. In the illustrated embodiment, the furniture fitting 1 is shown in an open position. When the movable furniture element 100 is opened or closed by a user, the movement is transmitted to the articulated arm assembly 20, which includes an articulated arm 21. The articulated arm 21 and the functional articulated arm 22 are therefore adjustably arranged on the base element 10, but can also be articulated exclusively with adjacent articulated arms without being attached to the base element.During the closing process of the movable furniture element 100, the functional articulated arm 22 of the articulated arm assembly 20 pivots in the direction of the arrow against the end face of a movable damper element 31 of the damper device 30. The damper device 30 and the articulated arm assembly 20, or the articulated arm 21, or the functional articulated arm 22, are thus operatively connected to each other at least over part of the pivot path of the articulated arm 21. During the opening process of the movable furniture element 100, the articulated arm assembly 20 is moved accordingly in the opposite direction of the arrow and away from the damper device 30.

[0051] The furniture fitting according to the invention comprises a damping device 30 with a movable damping element 31 and a fixed damping element 34, which are at least partially enclosed by a damping bracket 32. The movable damping element 31 is designed to dampen the movement of the functional joint arm 22 between a Fig. 1a shown damper start position and one, for example, in Fig. The damper end position shown in Figure 3 is axially adjustable relative to the fixed damper element. The damper bracket 32 ​​has a recess 33 in the illustrated view. A locking section 41 of the switching element 40 can positively lock the movable damper element 31 through this recess 33. The switching element 40 can be switched between a release position that releases the damper device 30 and a locking position that blocks the damper device 30. In the illustration shown, the switching element 40 is depicted in the locking position.

[0052] The movable damping element 31 has a cylinder and is suitable for damping the movement of the articulated arm assembly 20 or the functional articulated arm 22. The cylinder can be pressed by the articulated arm assembly 20 along the fixed damping element 34, which is designed as a piston rod with a piston.

[0053] In a closed end position of the cover, the movable damping element 31 remains in the damping end position after being moved into this position by means of a force-fit connection with the blocking section 41. In the blocking position of the switching element shown, the damping device 30 dampens exactly once more before the movable damping element 31 is permanently blocked by the blocking section 41 of the switching element 40 and the damping device 30 is accordingly switched off.

[0054] The switching element 40, which has a blocking section 41 and a main section 46, is rotatably arranged on the damper device 30 via a rotary axis 42 for switching between a release and a blocking position and can therefore be operated particularly easily and without tools if required.

[0055] In the illustrated embodiment, the furniture fitting 1 further comprises a main force storage unit 50, which is rigidly connected to the base part 10 on one side via a first spring arm 51. On another side, the main force storage unit 50 exerts a force on the articulated arm assembly 20 by means of a second spring arm 52 and an additional articulated arm assembly 70. The force counteracts the weight force and the movement of the movable furniture element 100 via the adjusting arm 21 of the articulated arm assembly 20.

[0056] The main force storage element 50 is designed as a U-shaped spring, preferably made of a metallic material, for example, spring steel. The main force storage element 50 assists the user when opening and closing the furniture in such a way that only a comparatively small amount of muscle force is required to move the mass of the movable furniture element 100. Furthermore, the damping prevents the movable furniture element 100 from striking the furniture body, which would otherwise be perceived as unpleasant.

[0057] Depending on the design of the furniture fitting 1, the main force storage unit 50 can store or transmit a comparatively high force, so that a relatively large and heavy movable furniture element 100 can be moved relatively easily by a user. The force exerted on the furniture element 100 by the furniture fitting 1 can be varied by means of a force adjustment device 70. To ensure that sufficient closing force is maintained when the furniture element 100 is in its closed position, even with a comparatively low force acting on it, a pressure device 60 is provided.

[0058] The pressure device 60 can, for example, be a spring-loaded component that can be arranged at different positions on the articulated arm assembly 20 depending on the forces acting upon it. Of course, the pressure device 60 can also be arranged on other components of the furniture fitting 1 to provide additional damping through pressure.

[0059] Fig. Figure 1b shows the interaction of the pressure device 60 with the functional articulated arm 22 of the articulated arm assembly 20. The pressure device 60 can, of course, also interact with other elements or areas of the articulated arm assembly 20. The pressure device 60 comprises a pre-tensioned compression spring (mostly concealed by a housing of the pressure device 60) and a pressure device head 61. A portion of the pressure device 60 is fixedly arranged on the side facing the functional articulated arm 22, thus causing the pressure device 60 to exert a compressive force towards the functional articulated arm 22 due to the pre-tension of the compression spring.

[0060] The illustrated view shows the interaction of a furniture fitting 1 in an open position (similar to the one in Fig. (as shown in Figure 1a). The functional articulated arm 22 of the articulated arm assembly 20 has a pressure contact section 23 with an actuating contour 24 on one side facing the pressure device 60. The pressure contact section 23 is designed to counteract the pressure force of the pre-tensioned compression spring of the pressure device 60. During movement of the articulated arm assembly 20, the actuating contour 24 interacts with the pressure device head 61 in such a way that the pressure device head 61 rolls along the actuating contour 24 under pressure during an opening or closing movement.

[0061] The positioning contour 24 has a detent section 25 in one end region, via which a snap mechanism is achieved when the movable furniture element 100, designed as a lid, is moved into a closed end position. Depending on the geometric design of the detent section 25, the snap mechanism can be comparatively strong or weak when closing or opening.

[0062] In Fig. Figure 2 shows a schematic representation of the damper device 30 and the switching element 40, with the switching element 40 arranged in a release position. In the release position, the damper device 30 can dampen without restriction. The damper device 30 has a movable damper element 31, which is designed as a cylinder of a damper, for example, a fluid damper in the form of a linear damper. Furthermore, the damper device 30 has a fixed damper element 34 with a piston and piston rod. A recess 33 is arranged in the damper holder 32, through which the locking section 41 of the switching element 40 can be positioned in a locking position against the movable damper element 31 in a force-fit manner. It is also conceivable, in principle, that a rotary damper could be used.

[0063] In the view shown, a movable furniture element 100 (not shown) is at least partially open, since the articulated arm assembly 20 is not in contact with the cylinder suitable for damping. Furthermore, the switching element 40 is shown in a release position, but can be moved to the locking position at any time by rotating it about the axis of rotation 42. Thus, by rotating the switching element 40 about the axis of rotation 42, it is possible to switch from the release position to the locking position – and vice versa.

[0064] The switching element 40 comprises, in addition to the locking section 41, a main section 46 and a force storage device 43 for the elastic preloading of the locking section 41. The preload of the force storage device 43 supports the preload due to the elasticity of the locking section 41, particularly when the locking section 41 is connected to the main section 46 via a hinge, such as a film hinge in the illustrated embodiment. Furthermore, the switching element 40 has a circumferential contour 44, which is arranged at a distance from the piston in the illustrated release position.

[0065] The damping interaction between movable damping element 31 and articulated arm arrangement 20 is in Fig. Figure 3 shows that the switching element 40 remains in the release position, allowing the movable damping element 31 to absorb and dampen the force transmitted by the movement of the articulated arm assembly 20. The articulated arm assembly 20 engages one end face of the movable damping element 31. With the switching element 40 in the release position, the damping device 31 can dampen without restriction and continuously. A furniture element 100 (not shown), movably mounted on the furniture fitting 1, is in an end position in the illustration, where the furniture element 100 is in a closed position against the furniture body.

[0066] Fig. Figure 4 shows the movable damper element 31 in a damper start position, in which it does not interact with the articulated arm assembly 20. A movable furniture element 100 is therefore in a position that is at least partially open. By rotating the switching element 40 in the direction of the arrow about the axis of rotation 42, the blocking section 41 was partially guided through the recess 33 into a travel space of the movable damper element 31.

[0067] By rotating in the direction of the arrow, the switching element 40 was thus switched from a release position to the depicted locking position. The energy storage device 43, which is arranged between the locking section 41 and the main section 46 of the switching element 40, preloads the locking section 41 so that it can be pressed radially towards the main section 46 by an additional force. This force can be generated by the movable damping element 31 when it is inserted along the fixed damping element 34 in the case of damping.

[0068] In the position of the switching element 40 shown, exactly one damping action can still occur, namely when the movable damping element 31, after switching to the blocking position (as shown), dampens for the first time by being pressed in. Afterwards, the movable damping element 31 is permanently blocked in a damping end position by the blocking section 41, and the damping is deactivated. Of course, it is also possible to switch from a blocking position to a release position by rotating the switching element 40 against the direction of the arrow to release the movable damping element 31 again.

[0069] Fig. Figure 5 describes the force-locking, blocking positioning of the blocking section 41 of the switching element 40 against the movable damper element 31 in the blocking position. The previously described additional force necessary for the force-locking is generated by the movable damper element 31. This is moved by a closing action of the movable furniture element 100 from the articulated arm assembly 20 along the fixed damper element 34, which is designed as a piston rod, from the in Fig. 4 damper start position shown in the Fig. 5 Damper end position shown within the damper mount 32 pressed.

[0070] The force transmission between the movable damping element 31 and the blocking section 41 is reinforced by the energy storage device 43, which is designed as a compression spring. This is in comparison to the one in Fig.In the arrangement shown in Figure 4, the components are partially compressed, thereby building up tension and essentially creating the force-fit connection. The blocking section 41 engages the travel range of the movable damper element 31 through the recess 33 in the damper bracket 32. In the illustrated view, this element remains in the damper end position even after the movable furniture element 100 is opened. The damping is thus permanently deactivated.
