Description

Technical Field

[0001] This invention relates to a furniture drive device for moving furniture components movably supported relative to a furniture body, particularly moving a furniture cover rotatable about a horizontal axis relative to the furniture body. The furniture drive device includes:

[0002] The housing can be installed on or within the furniture panel of the furniture body.

[0003] An adjusting arm device for moving movable furniture parts, wherein the adjusting arm device has at least one adjusting arm movably supported relative to a housing, on which the movable furniture parts can be fixed, wherein the adjusting arm device is movable at least between a first relative position and a second relative position, wherein in the first relative position the at least one adjusting arm is disposed inside the housing, and in the second relative position the at least one adjusting arm is disposed outside the housing.

[0004] The present invention also relates to a piece of furniture having a furniture body, furniture components movably supported relative to the furniture body, and a furniture drive device of an exemplary type for moving the movably supported furniture components.

[0005] The present invention also relates to a method for mounting furniture components on at least one furniture drive device of the type to be described. Background Technology

[0006] DE 20 2018 102 084 U1 illustrates a furniture drive mechanism with a housing that, in the installed state, is substantially entirely contained within a vertically extending furniture panel of the furniture body. In this way, the furniture drive mechanism can be integrated into the furniture panel of the furniture body in a compact and visually inconspicuous manner. In the delivery state, the adjusting arm assembly of the furniture drive mechanism is in a fully open position, with some adjusting arms protruding from the front opening of the housing. This has the disadvantage that, despite its compact construction, the furniture drive mechanism presents relatively high space requirements, necessitating a relatively large packaging size and also posing a risk of damage to the forward-protruding adjusting arms. Summary of the Invention

[0007] Therefore, the object of the present invention is to provide a furniture drive device of the aforementioned type while avoiding the disadvantages discussed above.

[0008] According to the present invention, this is solved by a furniture drive mechanism for moving furniture components movably supported relative to the furniture body, the furniture drive mechanism comprising:

[0009] The housing can be installed on or within the furniture panel of the furniture body.

[0010] An adjusting arm device for moving movable furniture parts, wherein the adjusting arm device has at least one adjusting arm movably supported relative to a housing, on which the movable furniture part can be fixed, wherein the adjusting arm device is movable at least between a first relative position and a second relative position, wherein in the first relative position the at least one adjusting arm is disposed inside the housing, and in the second relative position the at least one adjusting arm is disposed outside the housing.

[0011] The feature is that it is provided with at least one operating device, which is detachably connected to the at least one adjusting arm, and the adjusting arm device can move from a first relative position to a second relative position through the at least one operating device.

[0012] According to the present invention, at least one operating device is provided, which is detachably connectable to or connected to the at least one adjusting arm, and the adjusting arm device can be moved from a first relative position to a second relative position via the at least one operating device.

[0013] In other words, the operating device connected to or detachably connected to the at least one adjusting arm is configured as an opening aid, by which the at least one adjusting arm (in the state of being connected to the operating device) can be moved from a closed position to an open position. In the closed position, the at least one adjusting arm is located inside the housing, and in the open position, the at least one adjusting arm is located outside the housing.

[0014] Therefore, the entire adjusting arm assembly of the furniture drive unit is in a compact first relative position in the delivery state, in which the adjusting arm assembly is located inside the housing. After the furniture drive unit is installed on the furniture body in its compact delivery state, the user can remove the at least one adjusting arm from the housing by means of an operating device, in which the user applies manual force (preferably a manual pulling motion) to the operating device connected to the adjusting arm.

[0015] A particularly advantageous aspect of the operating mechanism is that the housing of the furniture drive mechanism is completely housed within the furniture panel of the main body of the furniture in the installed state. Without the operating mechanism, the user would therefore have to attempt, for example, to remove the at least one adjusting arm from the housing. This process can be very dangerous, especially when a spring mechanism is provided for force-loading the adjusting arm. The adjusting arm could therefore be uncontrollably deflected towards the open position by the force of the spring mechanism, posing a significant risk of injury or damage to the object. Furthermore, removing the adjusting arm from the housing carries the risk of damage, particularly abrasion, to the adjusting arm mechanism due to improper tool positioning.

[0016] According to one embodiment, the at least one operating device may have at least one recess for receiving a tool, preferably a screwdriver. The tool, preferably a screwdriver, can thus be inserted into the recess of the operating device, wherein an adjusting arm connected to the operating device can be controlled to move from a closed position inside the housing to an open position outside the housing by means of a lever arm extended from the screwdriver. This is particularly advantageous, as already mentioned, for the adjusting arm device of the furniture drive mechanism to be forcefully loaded by a spring device. In this way, the controlled opening movement of the adjusting arm device can be achieved by applying a reaction force using the tool.

[0017] According to one embodiment, it can be specified that,

[0018] The adjusting arm device is loaded by the spring device in a first relative position direction within a first pivot angle range and in a second relative position direction within a second pivot angle range, and / or

[0019] The spring device has at least one helical spring, preferably at least one compression spring.

[0020] The furniture according to the invention comprises a furniture body, furniture components movable relative to the furniture body, a furniture cover particularly deflectable relative to the furniture body about a horizontal axis, and a furniture drive device of the type described above for moving the movable furniture components. According to one embodiment, the housing of the furniture drive device may be substantially entirely housed within the furniture panel of the furniture body.

[0021] A method according to the invention for mounting furniture components onto at least one type of furniture drive device, characterized by the following method steps:

[0022] The housing of the at least one furniture drive device is disposed on the furniture board of the furniture body or in the furniture board.

[0023] The at least one operating device is used to move the adjusting arm device from the first relative position to the second relative position.

[0024] Release the at least one operating device from the at least one adjusting arm, and

[0025] The furniture component is secured to at least one of the adjusting arms. Attached Figure Description

[0026] Other details and advantages of the invention will be illustrated with reference to the accompanying drawings.

[0031] Figure 5a , 5b A perspective view of the furniture drive mechanism and a magnified detail view thereof are shown.

[0032] Figure 6a , 6b A side view and a cross-sectional view of the operating device connected to the adjusting arm are shown;

[0033] Figures 7a to 7d The diagram shows the adjusting arm device in two different relative positions, along with enlarged details of these positions. Detailed Implementation

[0034] Figure 1 shows a perspective view of furniture 1, which has a furniture body 2, furniture parts 3 movably supported relative to the furniture body 2, and at least one furniture drive device 4 for moving the movable furniture parts 3. Furniture 1 has furniture panels 6 in the form of side walls, an upper bottom 7, and a lower bottom 8. The movable furniture parts 3 may, for example, be configured as furniture covers 3a that are deflectable relative to the furniture body 2 about a horizontal axis.

[0035] In the illustrated embodiment, the housing 9 of the furniture drive device 4 is at least partially, preferably substantially completely, integrated into the sidewall configured as the furniture panel 6, wherein the movable furniture component 3 is movably supported between a closed position covering the furniture body 2 and an open position raised relative to the furniture body 2.

[0036] Of course, it is also possible to integrate the furniture drive device 4 into the horizontally extending furniture panel, that is, for example, into the upper bottom 7, the lower bottom 8, and / or into the partition 13 disposed between the upper bottom 7 and the lower bottom 8. Figures 2a to 2d In this case, the movable furniture component 3 is pivotally supported relative to the furniture body 2 about an axis that extends vertically in the installation position.

[0037] The furniture drive device 4 has an adjusting arm device 5 and at least one spring device 10. Figure 1b The adjusting arm device is used to move the movable furniture part 3, and at least one spring device is used to force the adjusting arm device 5.

[0038] Figure 1b An exploded view of furniture 1 is shown, in which two furniture drive devices 4, preferably identical in configuration, are provided for moving movable furniture parts 3. Each furniture drive device 4 has a housing 9 to be fixed to the furniture body 2. According to one embodiment, the housing 9 of the furniture drive device 4 may be specified to be at least partially, preferably substantially completely, accommodated within a notch 11 configured as a side wall of the furniture panel 6 in the installed state. In the installed state, the housing 9 may end substantially flush with the end side 6a of the furniture panel 6.

[0039] The notch 11 is configured as a pocket, for example, in which the housing 9 can be inserted into the pocket-shaped notch 11 of the furniture panel 6 from the front (i.e., from the narrow end side 6a of the furniture panel 6) during installation. In the installed state, the furniture drive device 4 is housed within a set wall thickness of the furniture panel 6.

[0040] At least one spring device 10 for force-loading the adjusting arm device 5 is provided in or on the housing 9. A cover 12 is provided on the front end region of the housing 9, wherein at least one movably supported adjusting arm 5a, 5b, 5c, 5d of the adjusting arm device 5 is located. Figure 2d It can be guided through the cover 12 in a relative position.

[0041] Figures 2a to 2d The illustration shows a piece of furniture 1 with a main body 2, wherein the housing 9 of the furniture drive mechanism 4 is substantially completely housed within the furniture panel 6. In addition to an upper bottom 7 and a lower bottom 8, the furniture 1 also has an additional partition 13. An adjusting arm device 5 for moving the movable furniture parts 3 is also completely housed within the housing 9 of the furniture drive mechanism 4, thus presenting the furniture drive mechanism 4 in a very compact configuration in its delivery state. In this way, the packaging size for the furniture drive mechanism 4 is reduced, and the adjusting arm device 5 is protected from damage.

[0042] To allow the adjusting arm device 5 to move out of the housing 9 of the furniture drive device 4, an operating device 14 is provided. This operating device 14 can be implemented as a separate component from the adjusting arm device 5, which can be connected to at least one adjusting arm 5a of the adjusting arm device 5. Figure 2c , Figure 2d It can be loosely connected.

[0043] The housing 9 of the furniture drive unit 4 has a front opening 17 through which at least one adjusting arm 5a can be guided. According to one embodiment, the front opening 17 of the housing 9 can be substantially completely covered by the operating device 14. In this way, the intrusion of dirt and dust into the interior of the housing 9 can be reduced.

[0044] The operating device 14 has a recess 15 for receiving a tool 16, preferably a screwdriver 16a. By introducing the screwdriver 16a into the recess 15 and then lifting the screwdriver 16a, the operating device 14 (together with the at least one adjusting arm 5a) can be moved out of the housing 9 of the furniture drive device 4. Figure 2b , Figure 2c ).

[0045] The adjusting arm device 5 is movably supported at least between a first relative position and a second relative position. In the first relative position, the at least one adjusting arm 5a is disposed inside the housing 9, and in the second relative position, the at least one adjusting arm 5a is disposed outside the housing 9.

[0046] Typically, the adjusting arm assembly 5 is loaded by the spring device 10 in a first relative position direction within a first pivot angle range and in a second relative position direction within a second pivot angle range. This means that the spring device 10 applies a closing force to the at least one adjusting arm 5a in the closing region immediately preceding the fully closed position. Figure 2a Therefore, a manual force must first be applied to overcome the force of the spring device 10 so that the adjusting arm device 5 can move from the first relative position (closed position) to the second relative position (open position).

[0047] Figure 2c The furniture 1 is shown in another open position of the adjusting arm assembly 5. From this relative position, the spring device 10 applies an opening force to the adjusting arm assembly 5. The user can thus prevent uncontrolled displacement of the at least one adjusting arm 5a by applying manual force against the force of the spring device 10 using a screwdriver 16a inserted into the recess 15.

[0048] According to a preferred embodiment, the at least one operating device 14 may be configured to be non-rotatably connected to the adjusting arm 5a in at least a first relative position, in which the at least one adjusting arm 5a is disposed inside the housing 9. In this way, no relative movement occurs between the operating device 14 and the adjusting arm 5a, thereby enabling controlled opening movement of the adjusting arm device 5.

[0049] exist Figure 2d In the middle, the adjusting arm device 5 of the furniture drive device 4 is in the fully open state. Now the operating device 14 can be separated from the adjusting arm 5a and, for example, recycled.

[0050] Figures 3a to 3d Different views of the operating device 14 are shown. Figure 3a A perspective view of the operating device 14 is shown. Figure 3b A front view of the operating device 14 is shown. Figure 3c The operating device 14 is shown along Figure 3b The cross-sectional view of plane AA shown is as follows, and Figure 3d A perspective view of a screwdriver 16a inserted into a recess 15 is shown.

[0051] Preferred implementation method:

[0052] The operating device 14 has a flat visible side 17 that faces away from the at least one adjusting arm 5a in the installed state of the operating device 14, and / or

[0053] The at least one recess 15 is inclined in the first relative position of the adjusting arm device 5 at (see) Figure 3c ) is formed by the front opening 17 of the housing 9 ( Figures 2a to 2d One of the planes formed extends, and / or

[0054] The at least one recess 15 has an access opening 19 ( Figure 3c ) and a stop 20 for tool 16 spaced apart therefrom, wherein the at least one adjusting arm 5a surrounds at least one hinge axis 25 ( Figure 4a The stop 20 is rotatably supported, and in the first relative position of the adjusting arm device 5, it is positioned closer to the at least one hinge shaft 25 than the entry opening 19, and / or

[0055] The at least one recess 15 is configured to be substantially cylindrical and / or conical, and / or

[0056] The adjusting arm device 5 has at least one adjusting arm 5a to be connected to the movable furniture part 3, and a tool 16 that can be accommodated in the at least one recess 15 can be provided on the extension of the adjusting arm 5a.

[0057] The operating device 14 can be releasably locked relative to the housing 9 of the furniture drive device 4 in the first relative position of the adjusting arm device 5 via the locking device 21. Preferably, wherein...

[0058] The at least one locking device 21 has at least one spring tongue 22, preferably at least two spring tongues 22 spaced apart from each other, and / or

[0059] The at least one locking device 21 has at least one recess 29 ( Figure 5a , Figure 5b The at least one locking element 23 is disposed in the at least one recess 29, wherein the at least one locking element 23 is disposed on the at least one operating device 14, and the at least one recess 29 is disposed in or on the housing 9 of the furniture drive device 4, or vice versa.

[0060] Furthermore, a locking device 24 is provided, by means of which the at least one operating device 14 or alternatively, an accessory element that can be connected to the movable furniture part 3, can be detachably connected to the at least one adjusting arm 5a. Preferably, the at least one locking device 24 is:

[0061] Includes at least one elastic or elastically loaded locking element 26. Figure 4b And at least one recess 24b for receiving a locking element 26, wherein the locking element 26 is disposed on the at least one adjusting arm 5a, and the recess 24b is disposed on the operating device 14 or on the accessory element, or vice versa, and / or

[0062] Includes at least one retaining pin 28 ( Figure 4b ) and at least one recess 24a for receiving a retaining pin 28, wherein the retaining pin 28 is disposed on the at least one adjusting arm 5a, and the recess 24a is disposed on the operating device 14 or on the accessory element, or vice versa, and / or

[0063] Includes at least one elastic or elastically loaded locking element 26. Figure 4b ) and at least one retaining pin 28 spaced apart from the locking element 26 Figure 4b ).

[0064] The accessory element is not shown in detail in the accompanying drawings. However, as is known, the accessory element is configured to be fixed to the movable furniture part 3 using the at least one adjusting arm 5a of the adjusting arm device 5 and is generally used for detachable connections, particularly for tool-less locking.

[0065] Figure 4aThe diagram shows the adjusting arm 5a of the adjusting arm assembly 5, pivotally supported around the hinge axis 25, in a state connected to the operating device 14. The operating device 14 can be releasably locked to the adjusting arm 5a by means of the locking device 24.

[0066] Figure 4b Showing according to Figure 4a The cross-sectional view of the arrangement shows the locking device 24 in detail. To install the operating device 14, the retaining pin 28 of the adjusting arm 5a is first inserted into the groove 24a of the operating device 14. In the suspended state, the operating device 14 is deflected and then releasably locked by the locking element 26 of the movable support. The locking element 26, provided on the adjusting arm 5a, is pre-tensioned to the locked position by an accumulator 27, for example, a leaf spring. In the locked state, the locking element 26 of the adjusting arm 5a is engaged in the recess 24b of the operating device 14.

[0067] The at least one adjusting arm 5a has at least one mounting member 39 on which a movable furniture component 3 can be fixed, and the at least one adjusting arm has at least one adjusting device 38a, 38b, 38c, by means of which the position of the at least one mounting member 39 relative to the at least one adjusting arm 5a is adjustable. In the illustrated embodiment, the at least one adjusting arm 5a has three adjusting devices 38a, 38b, 38c with operating elements having three rotatable supports. By means of the adjusting devices 38a, 38b, 38c, the position of the furniture component 3 relative to the adjusting arm 4a is adjustable in three dimensions about the adjusting arm 5a in the installed state of the furniture component 3.

[0068] The position of the operating device 14 (or alternatively, the position of the accessory element to be fixed on the movable furniture part 3) is adjustable in the lateral direction with respect to the adjusting arm 5a via the first adjusting device 38a. The tilt of the mounting part 39 relative to the adjusting arm 5a is adjustable via the second adjusting device 38b. The height of the mounting part 39 relative to the adjusting arm 5a is adjustable via the third adjusting device 38c.

[0069] Figure 5a A perspective view of the furniture drive mechanism 4 is shown. The housing 9 of the furniture drive mechanism 4 has two substantially flat housing walls 9a and 9b that are parallel to each other and spaced apart. Between the two housing walls 9a and 9b, the adjusting arm device 5 is fully accommodated inside the housing 9 in its first relative position. A spring device 10 for force-loading the adjusting arm device 5 can also be seen. The spring device 10 may, for example, have a spring assembly having a plurality of helical springs, preferably compression springs, connected in parallel.

[0070] At least one recess 29 is provided on the housing 9, which is configured to receive a locking element 23 of the operating device 14. Figure 3a In this way, undesirable opening movements of the adjusting arm device 5 are prevented. It is particularly advantageous that the spring device does not apply a closing force to the at least one adjusting arm 5a in the closed region, but rather applies a torque acting in the opening direction to the at least one adjusting arm 5a even in the closed region.

[0071] According to one embodiment, the operating device 14 has at least two mutually separated locking elements 23. A first locking element 23 of the operating device 14 can be received in a first recess 29 of the first housing arm 9a. A second locking element 23 of the operating device 14 can be received in a second recess 29 of the second housing arm 9b. In this way, the operating device 14 can be locked in a tilt-resistant manner relative to the housing 9.

[0072] Figure 5b Shown in Figure 5a An enlarged view of the circled area. The locking element 23 may be at least partially configured as a cylinder and is received in a circular recess 29 of the housing 9. The locking between the locking element 23 and the recess 29 can be released by manually pulling on the operating element 14, thereby allowing the locking element 23 to move out of the recess 29 against its elasticity. The at least one locking element 23 is movably supported in a direction extending substantially perpendicular to the plane formed by the housing arms 9a, 9b.

[0073] exist Figure 5b Furthermore, it can be seen that a cover 12 is provided on the housing 9 of the furniture drive device 4, the cover having at least one laterally protruding flange 12a that is substantially annular. This flange 12a is configured to abut against the end side 6a of the furniture panel 6. Figure 1b The flange 12a serves as a depth stop for the housing 9 of the furniture drive device 4, thereby allowing the housing 9 to occupy a defined depth position relative to the furniture board 6 in the installed state. Furthermore, the flange 12a can cover the area between the housing 9 and the notch 11 in the installed state of the furniture drive device 4. Figure 1b The gap between the inner walls.

[0074] Figure 6a A portion of the adjusting arm assembly 5 is shown, wherein at least one adjusting arm 5a is hinged to adjusting arm 5b via a hinge shaft 30, and at least one adjusting arm is hinged to adjusting arm 5c via another hinge shaft 30.

[0075] The furniture drive device 4 has a releasable locking device 31, wherein the pivoting movement of the adjusting arm device 5 from the second relative position to the first relative position can be locked by the at least one locking device 31.

[0076] The releasable locking device 31 includes at least two locking elements 31a, 31b that are movably and preferably pivotally supported about rotation axes 32a, 32b, the locking elements being movably supported relative to each other between a locked position and at least one released position. In the locked position of the locking elements 31a, 31b, the movement of the adjusting arm device 5 between a first relative position and a second relative position is lockable. In the released position of the locking elements 31a, 31b, the movement of the adjusting arm device 5 between the first relative position and the second relative position is releasable. The at least two locking elements 31a, 31b of the locking device 31 are abutted against each other in the locked position and / or spaced apart from each other in the released position. At least one locking element 31a, 31b, preferably two locking elements 31a, 31b, may be configured as a double-arm rod with two rod ends.

[0077] The at least one adjusting arm 5a has at least one mounting member 39 on which a movable furniture part 3 can be fixed, and the at least one adjusting arm has at least one adjusting device 38a, 38b, 38c, by means of the at least one adjusting device, the position of the at least one mounting member 39 relative to the at least one adjusting arm 5a is adjustable, wherein at least one locking element 31a of the locking device 31 is movably, preferably pivotally, supported on the at least one mounting member 39.

[0078] In the example shown Figure 6a , Figure 6b In this configuration, locking elements 31a and 31b are in the released position, allowing the adjusting arm device 5 to move between a first relative position and a second relative position. The release position exists because the operating device 14 is connected to at least one adjusting arm 5a as specified. This is evident here because the retaining pin 28 of the adjusting arm 5a is embedded in the groove 24a of the operating device 14.

[0079] The first locking element 31a is pivotally supported about the first rotation axis 32a, wherein the first locking element 31a is pre-tightened counterclockwise about the first rotation axis 32a by an accumulator 33 (not visible here) and thus abuts against the operating device 14 by the force of the accumulator 33.

[0080] The second locking element 31b is pivotally supported about the second rotation axis 32b, wherein the second locking element 31b is pre-tightened clockwise about the second rotation axis 32b by the accumulator 33 shown and thus abuts against the support element 35 of the adjusting arm 5a by the force of the accumulator 33.

[0081] In the predetermined connection state between the operating device 14 and the at least one adjusting arm 5a, the two locking elements 31a and 31b are spaced apart, thereby releasing the movement of the adjusting arm device 5 between the first relative position and the second relative position. In the released position, the locking elements 31a and 31b are spaced apart in all relative positions of the adjusting arm device 5, which from... Figure 6a , 6b I learned this from the middle.

[0082] on the contrary, Figure 7b The diagram shows the separated state between the operating device 14 and the at least one adjusting arm 5a, whereby the releasable locking device 31 is in the locked position. In the locked position, movement of the adjusting arm device 5 between a first relative position and a second relative position is lockable or at least restricted. The separated state between the operating device 14 and the adjusting arm 5a is evident from the fact that the retaining pin 28 of the adjusting arm 5a is no longer engaged in the groove 24a of the operating device 14.

[0083] In the example shown Figure 7a In this configuration, the adjusting arm device 5 is in a fully open state relative to the housing 9 of the furniture drive device 4. The position of the adjusting arm device 5 at its maximum open position relative to the housing 9 can be adjusted using an adjusting device known in the prior art. In this way, the flexibility in mounting the movable furniture component 3 onto the at least one adjusting arm 5a is improved, because by variably adjusting the maximum open position, the adjusting arm device 5 can be moved to a position comfortable for the user.

[0084] The releasable locking device 31 is configured to prevent the spring device 10 from clamping during the movement of the adjusting arm device 5 from the second relative position (open position) to the first relative position (closed position) as long as no movable furniture part 3 is connected to the adjusting arm 5a. Since no movable furniture part 3 is connected to the adjusting arm 5a, there is no force acting against gravity on the spring device 10. Therefore, it is possible that the adjusting arm 5a would uncontrollably deflect towards the open position when no furniture part 3 is connected. The releasable locking device 31 locks the movement of the adjusting arm device 5 from the open position to the closed position, thus preventing the spring device 10 from clamping.

[0085] As from Figure 7aIt is understood that, due to the lack of operating device 14, the force of the accumulator 33 (not shown) causes the first locking element 31a to deflect clockwise around the first rotation axis 32a. Here, the longer arm of the first locking element 31a abuts against the second locking element 31b, thereby causing the second locking element 31b to deflect counterclockwise around the second rotation axis 32b.

[0086] The accumulator 33 used to load the first locking element 31a is configured to be more rigid than the accumulator 33 used to load the second locking element 31b, so that the first locking element 31a allows the second locking element 31b to reliably move around the second rotation axis 32b.

[0087] Figure 7b Show Figure 7a An enlarged view of the circled area. It can be seen that the second locking element 31b has a stop 36 that can abut against the corresponding stop 37 of the adjusting arm 5c.

[0088] Figure 7c The diagram illustrates the continuous pivoting movement of the adjusting arm device 5, wherein the stop 36 of the second locking element 31b now abuts against the corresponding stop 37 of the adjusting arm 5c, thus preventing further pivoting movement of the adjusting arm device 5 towards the first relative position (closed position). In the locked position of the locking device 31, the adjusting arm device 5 can be pivoted only from... Figure 7a The position shown moves to Figure 7c In the position shown, the spring device 10 can no longer be clamped for safety reasons.

[0089] When the operating device 14 or the movable furniture part 3 is installed on the adjusting arm 5a, the releasable locking device 31 automatically switches back to the released state.
