Description

  The present invention relates to a furniture unit that is supported by furniture in a movable state, and more particularly to a fixing device for braking (stopping) extraction (drawer) at a closed end position.

  The securing device includes at least one locking device (an anchor) having a receiving element for the engaging element. One of the receiving element and the engaging element is attached to the furniture, and the other element is attached to the movable furniture portion. These two elements are operably connected at least in the closed end position of the movable furniture section.

  Such fixing devices are known per se and adjust the front gap that exists in the closed position between the inside of the front panel and the front end surface of the furniture body or frame wall. Can do.

  For example, Patent Literature 1 discloses a door device for closing a furniture door, which is a sphere that is captured by a locking tool that is installed on the door and the engaging element is attached to the furniture frame. This sphere is fixed to a rod body with a thread groove, and the position of the sphere is variable with respect to the depth direction of the furniture. The front gap remaining between the door and the furniture frame can now be adjusted. However, this method has a short displacement distance of the engagement element and is inaccurate adjustment.

German Patent Application No. 2174139

  Accordingly, it is an object of the present invention to provide a locking device as described above that allows a simple change of the front gap and that has a structurally simple and accurate adjustment mechanism.

  According to the invention, the object is to make the relative position of the receiving element relative to the engaging element linearly variable in the depth direction of the furniture by means of a displacement device designed to convert rotational movement into translational movement. Is achieved.

  According to the invention, in one preferred embodiment of the invention, the lock is rotated between the first release position of the engagement element and the second braking position of the engagement element to accommodate the front gap. The fact that only the position of the receiving element supported by the formula is changed is easier to adjust compared to the prior art and allows a more stable structure.

  A policy that is technically easy to implement can be configured as follows. That is, the at least one locking device includes a slide portion that is movably supported linearly with respect to the base, and the receiving element is installed on the slide portion. Here, it is advantageous if the displacement device for changing the relative position of the receiving element is constructed and designed to act directly on the slide part. In this case, it is particularly advantageous if the receiving element is installed in a rotary manner on a linearly movable slide.

  In such a configuration, the two functions “rotating the receiving element and changing the position of the receiving element with respect to the depth direction of the furniture” are realized by different mechanisms, simultaneously achieving a general increase in stability and a simplified structure. It is possible.

  According to another embodiment of the invention, the locking device includes a blocking mechanism for releasably securing the receiving element, which is preferably pivotally supported, in the braking position of the engagement element. In this case, the release of the braking action of the engaging element by the receiving element at the closed end position of the movable furniture part is provided by the acting force acting on the movable furniture part or the movement of the movable furniture part in the closing direction. For this purpose, the blocking mechanism preferably has a cardioid slide guide track or pawl.

  According to another embodiment of the present invention, if the locking device has a slide part supported so as to move linearly with respect to the base part, the blocking mechanism is preferably a linearly moving slide part, preferably The slide part, which is configured and configured to operate with a receiving element that is rotationally mounted thereon and is supported in a linearly movable manner, can preferably have a cardioid slide guide track.

  In one preferred embodiment, the displacement device comprises an actuating element that is rotatably supported, the axis of rotation of the actuating element being substantially perpendicular to the main plane of the locking device.

  In another embodiment of the invention, the actuating element is rotatably supported at the base of the locking device, where the actuating element is preferably on a slide part which is supported in a linearly movable manner by a spiral slide guide track. Is operably connected to the guide means installed in the. In this way, a light operation of the displacement device is possible and a stepless position change of the receiving element is ensured. If this is a self-locking type, the receiving element remains in that position everywhere once it has been positioned without further manipulation.

  Although it is basically possible for the receiving element to be installed in the furniture and the engaging element to be installed in the movable furniture part, in a preferred embodiment of the invention the receiving element is installed in the movable furniture part, The engagement element is installed in a stationary state on the furniture.

  In this respect, if the engagement element has a plate-like main element with a pin thereon, and its longitudinal axis is substantially perpendicular to the main plane of the main element, it is structurally simple. Configuration is provided.

  In an embodiment of the invention which is of particular space saving type, the engaging element is fixedly mounted on the frame rail of the extraction guide system which is a movable furniture part. In this case, it is particularly desirable that at least one locking device is extracted and installed on the lower side. If the fixing device is installed in the front area of the furniture at the closed end position of the movable furniture part, it is particularly convenient and comfortable for the installation worker or user to access the fixing device.

  In one preferred embodiment of the invention, the securing device has at least two locks operatively connected by a synchronization mechanism. The synchronization mechanism has at least two coupling elements respectively associated with different locking devices and at least one synchronization device, which are movably coupled by the synchronization devices.

  In such a configuration, the locking of the receiving element with the engagement element (mooring) substantially simultaneously causes the two locks on both sides of the movable furniture part to be closed against the front panel in the closing direction of the movable furniture part. It is unlocked (unlocked) regardless of the position where the user applies pressure. That is, it is irrelevant whether the user applies pressure to the right, left or center of the front panel thanks to the connection.

  A simple structure is possible if the synchronizer has a base element that is installed in an immobile state on which the synchronizer is rotatably supported. The first embodiment of the synchronization element is a gear, and the synchronization tool is movably mounted for translation on the base element, is engaged on both sides of the synchronization element, and is connected to the connecting element at one end. It has two racks connected to each other.

  Other forms of synchronization elements are possible. That is, the synchronization element may be, for example, a double arm type lever.

  In another embodiment of the present invention, at least one locking device may be It has an overload safety mechanism including at least two members connected in a movable state.

  In this regard, in another embodiment of the present invention, the overload safety mechanism is rotatably coupled to each other and has two members that rotate between a first end and a second end. . Between the first end and the second end, the holding device operates to act to hold or return the members that are rotationally connected to the first end position in a releasable manner.

  In another embodiment of the invention, the receiving element has a base element and a locking element movably connected to the base element, and the blocking mechanism acts on the base element. It is desirable that at least two movably connected members of the overload safety mechanism are a base element and a locking element of the receiving element, providing a simple structure.

  Although the concept of the present invention can be implemented even if only one of the two locking devices has a blocking mechanism or an overload safety mechanism, in a preferred embodiment of the present invention, each locking device has a blocking mechanism. And / or have an overload safety mechanism.

  The invention also relates to a locking release device for a movable furniture part movably supported on the furniture. The discharge device includes a discharge element that is actuated by a force storage means and a securing device.

  Such a lockable release device opens the movable furniture part without a handle to the extent that at least the back of the front panel can be grasped and the movable furniture part can be opened without a handle. In this case, the release device can be released, for example, with a button. Also, in the so-called touch latch configuration, the discharge device can be released by applying pressure to the front panel in the closing direction of the movable furniture portion.

  In this respect, in one preferred embodiment of the invention, the locking of the discharge device is provided by a blocking mechanism for the receiving element.

  In another embodiment of the invention, the discharge device or discharge element is installed on a lock.

  However, in another embodiment of the invention, the discharge device or discharge element is installed separately from the fixing device of the movable furniture part. In this respect, the discharge device or discharge element is installed in an extraction guide system (preferably a furniture frame) which is a movable furniture part.

  The present invention further relates to a furniture having a fixing means according to any one of claims 1 to 26, and further to a furniture having a lock-type discharge device according to any one of claims 27 to 29. Also related.

  FIG. 1 illustrates furniture having a movable furniture portion 2 supported in a movable state. In this case, the opening operation of the movable furniture part 2 that is the extraction is provided by the touch latch mechanism. That is, the user applies a force to the front panel 3 in the form of a non-gripping part (handle), thereby closing the movable furniture part 2 by a predetermined distance in the depth direction (closing direction SR) of the furniture 1. Push in. As a result, the release device is unlocked and the movable furniture part 2 extends to the open position outside the furniture by the release device.

  FIGS. 2 a and 2 b illustrate the underside of the movable furniture part 2 that is supported in a movable state by the furniture 1. In this case, the movable furniture section 2 is extracted by the frame rail 13 fixedly installed on the frame 4 of the furniture 1 and is movably guided by the rail 23. In the region of the front panel 3, a fixing device 5 for braking (locking) the movable furniture part 2 at the closed end position E is provided on the lower side 25 of the movable furniture part 2. The fixing device 5 includes a locking device 6 having a receiving element 7. The receiving element 7 engages with the engaging element 8 that is installed in a stationary state on the frame rail 13 at least at its closed end position E.

  In the embodiment shown in FIGS. 2a and 2b, in order to vary the front gap F corresponding to the space between the front panel 3 and the furniture frame 4 at the closed end position E of the movable furniture part 2, that is, In order to vary the release distance for the touch latch mechanism, the receiving element 7 of the engagement element 8 is placed on the slide part 10 supported in a linearly movable manner at the base 11 of the locking device 6. The locking device 6 has a displacement device 9, whereby the relative position of the receiving element 7 with respect to the engaging element 8 is variable in the depth direction of the furniture 1.

  The displacement device 9 is designed to convert rotational movement into translational movement and for this purpose has an actuating element 12 that is supported in a rotational manner. The rotation axis f is substantially orthogonal to the main plane of the lock tool 6. In this embodiment, the actuating element 12 acts directly on the slide part 10 supported so as to be linearly movable.

  The engagement element from the position shown in FIG. 2a having a front gap F between the front panel 3 and the furniture frame 4 and a space A between the slide part 10 and the base part 11 of the lock 6 The relative position of the receiving element 7 with respect to 8 can be changed by rotating the actuating element 12 of the displacement device 9. As a result, as shown in FIG. 2b, a front gap F 'that is increased and a space A' that is reduced are obtained. Variations in the relative position of the receiving element 7 relative to the engaging element 8 are performed in both directions, and the front gaps F, F 'are inversely proportional to the spaces A, A'. That is, the front gaps F and F 'are increased, and the spaces A and A' between the slide part 10 and the base part 11 are reduced accordingly. The opposite happens. Due to this advantageous form of the fixing device 5 and the configuration of the lower side 25 of the movable furniture part 2 in the area of the front panel 3, the user can easily adjust the front gaps F, F ′ without tools, and the closed end The position of the movable furniture part 2 at the position E can be changed.

  A frame rail 13 installed on or installed on the furniture frame 4 is shown in FIG. An engaging element 8 is installed at the front end of the frame rail 13, and a discharge device 18 is installed at the rear end. The frame rail 13 is attached to the furniture 1 such that the engaging element 8 is present in the front area of the furniture.

  FIG. 4 is an exploded view of the discharge device 18. In the example shown, the discharge device 18 has a two-part housing 21, 21 '. The discharge element 20 having the abutment 22 provided thereon and received by the action force storage means 19 is supported in a movable state. In this embodiment, the locking of the discharge device 18 is performed by the engagement element 8. The engaging element 8 is braked by the receiving element 7 of the locking device 6 at the closed end position of the movable furniture part 2. After the release device 18 is released, that is, after the engaging element 8 is released from the locking device 6, the action force storage means 19 is unloaded and moves the release element 20. The movement is extracted by the abutment 22 and moved to the rail 23 or directly moved to the movable furniture portion 2.

  The engaging element 8 shown in FIG. 5 has a plate-like main element 13 that is securely locked to the frame rail 13 by the hanging head 17 of the extending portion 16. A pin 15 is installed on the plate-like main element 13 at the end of the engaging element 8 that is opposite to the hanging head 17. The axis L of the pin 15 extends perpendicular to the main surface of the main element 13. In the closed end position E of the movable furniture part 2, the engaging element 8 is engaged by the receiving element 7 of the lock 6 and the pin 15, the movable furniture part 2 is braked in the closed end position E, and the discharge device 18 is Is locked.

  FIG. 6 illustrates the lower side of the movable furniture part 2. In this example, the movable furniture part 2 is an extraction, and the fixing device 5 is installed on the lower side 25 in the area of the front panel 3. The fixing device 5 has two locking devices 6 connected by a synchronization mechanism 24. Each of these two locking devices 6 has a receiving element 7. Each receiving element 7 engages with an engaging element 8 installed on two frame rails 13. In the case of this example, the movable furniture portion 2 is supported by the extracted rail 23 of the frame rail 13 in a movable state.

  FIGS. 7 a and 7 b illustrate the embodiment of FIG. 6 at two different positions of the movable furniture part 2. In this example, FIG. 7 a shows the movable furniture part 2 in the closed end position E, and the two receiving elements 7 of the locking device 6 engage with the engaging element 8 on the frame rail 13. The connection of the locking device 6 by the synchronization mechanism 24 is performed by the connection element 26. In the illustrated example, the coupling element 26 has a rod shape, one end of which is connected to the receiving element 7 in a rotational manner, and the other end thereof is connected to the synchronization tool 27 in a rotational manner.

When the movable furniture 2 is pushed into the furniture frame 4 (closing direction SR) by applying an acting force to the front panel 3 from the closed end position E shown in FIG. 7a, the blocking mechanism 31 is released and received. The locking action between the element 7 and the engagement element 8 is removed, and the receiving element 7 releases the engagement element 8 with the release device from the second position s ₁ shown in FIG. It is rotated in the second position _{s 2} in Figure 7b to.

  By the connection of the two locking devices 6 installed on both sides of the movable furniture part 2 by the synchronization mechanism 24, the elimination of the locking action and the starting of the discharge device are realized substantially simultaneously. This action is independent of the position of the front panel 3 where the user applies the starting force required in the closing direction SR of the movable furniture part 2.

  In order to achieve this object, the synchronization mechanism 24 includes a synchronization tool 27. The receiving element 7 of the locking device 6 is connected to the synchronizing device 27 by a connecting element 26 which is connected so as to move in a reverse relationship.

  In the embodiment shown in FIGS. 7 a and 7 b, after the release of the blocking mechanism 31, the receiving element 7 shown on the right side is rotated to the right side by the extension movement of the movable furniture part 2 and is synchronized by the connecting element 26. Pull 27 racks 30 to the right. In the illustrated example, the second rack 30 of the synchronization tool 27 is moved to the left in the figure by a synchronization element 29 which is a gear. On the contrary, the connecting element 26 shown on the left side of the figure moves from right to left, and the left receiving element 7 rotates to the left. Thus, the illustrated embodiment, which is coupled to operate in the opposite direction, reverses the direction of motion and reverses the tensile and pushing forces.

FIG. 8 shows another embodiment. Here, the locking device 6 further includes an overload safety mechanism 32. This ensures a safe opening of the movable furniture part 2 even if the receiving element 7 is fixed in the second position s _{2 where} the engagement element 8 is braked by the blocking mechanism 31.

  To achieve this purpose, as shown in FIG. 9a, the receiving element 7 has a two-part structure, the base element 43 and the locking element 44 are pivotally connected, and the blocking mechanism 31 has a base part. Acts on element 43. The base element 43 and the locking element 44 of the receiving element 7 of this embodiment form two parts of the overload safety mechanism 32. They are connected in a pivotal manner and can rotate between a first end position and a second end position. The holding device 33 operates between the base element 43 and the locking element 44. The mode of operation of the overload safety mechanism 32 will be described in more detail below using FIGS. 30a to 30g.

  9a and 9b, the movable furniture part 2 can be opened by applying a starting force to the front panel 3 in the closing direction SR (FIG. 9a). Thus, the blocking mechanism 31 is released, and it is not necessary to start the overload safety mechanism 32. In other respects, the embodiment of FIGS. 9a and 9b corresponds to the embodiment of FIGS. 7a and 7b. For this reason, detailed description is omitted.

  A first preferred embodiment of the synchronizer 27 is illustrated in the perspective view of FIG. The synchronizer 27 includes a base element 28, in which the synchronizer 29 is pivotally supported. In the illustrated embodiment, the synchronization element 29 is formed of a gear and is supported so that the two racks 30 translate on the guide track of the base element 28 on both sides of the synchronization element 29 engaged therein. Has been.

  FIGS. 11a and 11b are plan views of two different positions of the synchronizer 27 of FIG. Starting from the position of FIG. 11a, the two racks 30 are pressed or pulled in both directions by the rotation of the receiving element 7 of the locking device 6 (FIG. 11b). Here, the movement of the rack 30 in the opposite direction is linked to the rotating synchronization element 29 and is in a synchronous relationship.

  In order to fix the synchronization tool 27 to the movable furniture part 2, the base element 28 has an opening 34 which is in the form of a slot in the illustrated embodiment. The synchronizer 27 is connected to the coupling element 26 by a receiving opening 35 provided at the outer end of the rack 30.

  Another embodiment of the synchronizer 27 is illustrated in FIGS. 12-14b. The synchronizer shown in the perspective view of FIG. 12 is different from that of the embodiment of FIG. That is, the base element 28 has a two-part structure. As can be seen in FIG. 13, which illustrates an exploded view of the embodiment of FIG. 12, the base element 28 has a main element 41 and an intermediary element 42, and the synchronization element 29 and the two racks 30 have their intermediaries. Located on element 42.

  In this embodiment, the main element 41 has two through openings 39 for receiving the fixing means 36. Thus, the main element 41 is fixed to the movable furniture part 2. The receiving element 40 installed on the main element 41 fixes the mediating element 42 to the main element 41. A slot 34 is provided on the mediating element 42 for this purpose. In the illustrated embodiment, the fixing of the mediating element 42 to the main element 41 is performed by the guide pin 38 and the fixing element 37.

  This structure allows the rack 30 or connecting element 26 to avoid stresses due to screwing of the base element 28 to the underside of the movable furniture part 2, for example to the bottom of the extraction. Thanks to the two-part structure of the base 28, the main element 41 can be mounted on the lower side 25 of the movable furniture part 2 in the first stage. In this case, in order to brake the mediating element 42, the fixing element 37, which is a tightening screw, is first released, and the tightening is performed after the synchronization tool 27 is mounted on the movable furniture portion 2. As a result, the synchronizer 27 can be mounted substantially without stress.

  14a and 14b illustrate two different mounting positions of the synchronizer 27 of FIG. As shown in FIG. 14 b, the main element 41 and the mediating element 42 are in a harmonious relationship, and as shown in FIG. 14 a, the mediating element 42 is moved to the right side with respect to the main element 41.

  The embodiment of FIG. 15 differs from the embodiment of FIG. In this embodiment, as shown in particular in FIGS. 16a and 16b, the synchronization element 29 is formed by a double arm lever. This lever has receiving openings 35 at both ends for connection to the coupling element 26.

  On the other hand, the synchronization element 29 is mounted on the base element 28 in a rotational manner. Similar to the previous embodiment, the movement of the receiving element 7 is transmitted to the synchronizer 27 by the coupling element 26, but in this embodiment the coupling element 26 is directly connected to the synchronization element 29. . As in the case of the embodiment using two racks and vehicle teeth, in this embodiment, the two connecting elements 26 are connected so as to operate in an inverse relationship by a synchronizing element 29 which is a double arm lever.

  The two anchoring devices 6 are synchronously connected by the synchronization mechanism 24 having the synchronization device 27 and the two connection elements 26, and the fixing device 5 is viewed from above in FIG. 17a and from below in FIG. 17b. It is illustrated as such. In this case, the synchronization element 29 of the synchronization tool 27 is a double arm lever.

  The locking device 6 of the embodiment of FIGS. 17a and 17b is illustrated in an exploded view in FIG. The locking device 6 is fixed to the movable furniture portion 2 by the base portion 11. Among them, the slide part 10 is movable linearly. The position variation of the slide part 10 with respect to the base part 11 is performed by a displacement device 9 having an actuating element 12. The actuating element 12 is attached to the base 11 so as to rotate around the rotation axis f. Below that, there is a spiral slide guide track (not shown) operatively connected to the guide means 47 mounted on the slide unit 10 in the direction of the slide unit 10. That is, the rotation of the actuation element 12 causes a linear displacement of the slide part 12.

  The receiving element 7 is mounted on the slide portion 10 so as to rotate around the rotation axis d. In the embodiment shown, the receiving element 7 has a two-part structure and has a base 43 that is pivotally supported and a locking element 44 that is pivotally connected to the base 43. At the same time, the base 43 and the locking element 44 form two pivotally connected portions of the overload safety mechanism 32 and are connected by a holding device 33 which is a tension spring.

In the illustrated embodiment, the blocking mechanism 31 for braking the receiving element 7 at the position s ₁ for braking the engaging element 8 includes a slide guide track 45 and is supported in a rotational manner there by the linearly movable slide part 10. , Acting between the receiving element 7 which is acted upon by the spring 46.

  Another embodiment of the locking device 6 is illustrated in an exploded view in FIG. 19a and a perspective view in FIG. 19b. The embodiment of FIGS. 19a and 19b differs only in that it uses a different shaped member than the embodiment of FIG. The operating mode of the mooring tool 6 corresponds to that of the previous embodiment. For that reason, it will not be described in detail here.

  20a and 20b illustrate the locking device 6 illustrated in FIG. 19b installed on the movable furniture part 2, respectively. Here, the locking device 6 is engaged with the braking element 8, and is connected to the second locking device 6 installed on the opposite side of the movable furniture portion 2 by a connecting element 26 that is a part of the synchronization mechanism 24. Yes.

  In this case, the rotation of the actuating element 12 of the displacement device 9 changes the front gap F or the space A between the slide part 10 and the base 11 from the position shown in FIG. F ′ or a smaller space A ′ (FIG. 20b). That is, the position of the movable furniture portion 2 in the furniture frame 4 in the depth direction of the furniture 1 can be easily adjusted by the user by rotating the operating element 12 of the displacement device 9.

  In the embodiment shown in the drawings from FIGS. 21 a to 22 b, the part of the overload safety mechanism 32 that is connected in two pivots is formed by the base 43 and the locking element 44 of the receiving element 7. Unlike the embodiment of FIGS. 18 and 19, in this embodiment the holding device 33 has a two-part structure, the first part 50 is installed on the locking device 44 and the second part 51 is , Installed on the base element 43. In this case, the first part 50 of the holding device 33 is in the form of a hanging head, the second part 51 of the holding device 33 is in the form of a hanging receiving means, and the holding device 33 is positive (positive). Acts in a locking relationship.

  21a is a perspective view of the embodiment in the open position of the holding device 33, and FIG. 21b is an exploded view of the holding device 33 of FIG. 21a. FIG. 22a illustrates the configuration principle of the embodiment of FIG. 21a as a plan view. The holding device 33 is closed. In other words, the movable furniture portion 2 is disposed at the closed end position E, and the locking element 44 brakes the pin 15 of the braking element 8. When the movable furniture part 2 is pulled in the opening direction OR without releasing the blocking mechanism 31 by pushing the movable furniture part 2 in the inner closing direction SR, the holding device 33 exerts the pin 15 against the lock element 44. Open by acting force. That is, the positive locking connection between the members 50 and 51 is released and the movable furniture part 2 can be moved to the open position without damaging the receiving element 7.

The embodiment of the receiving element 7 with the blocking mechanism 32 shown in FIGS. 23a to 24b operates in a similar manner to the embodiment shown in FIGS. 21a to 22b. The embodiment of FIGS. 23 a to 24 b differs from that of FIGS. 21 a to 22 b in the characteristics of the two members 50, 51 of the holding device 33. In this embodiment, the two members 50 and 51 of the holding device 33 are formed of two magnets that attract each other.

  A very similar embodiment is illustrated in FIGS. Again, this embodiment differs in the nature of the two members 50, 51 of the holding device 33. The first member 50 of the holding device 33 is a magnet, and the second member 51 of the holding device 33 is in the form of a loop configured by being supported by two springs 52 present on the base element 43 of the receiving element 7. It is a counter-polar metal.

  This form has the following advantages. That is, the separation force between the two members 50 and 51 increases when the separation force acts between the two members 50 and 51, particularly as shown in FIGS. That is, first, the separation force between the members 50 and 51 of the holding device 33 is related to the inclined position of the member 51 of the holding device 33 before the member 50 is actually separated. Therefore, the acting force of the discharge device increases, and the reaction of the movable furniture part 2 during the closing operation is at least partially absorbed by the holding device 33.

  Figures 29a to 29d illustrate different positions of the receiving element 7 of the locking device 6 according to the embodiment shown in Figure 20a during a normal opening operation. This normal opening operation is to release the mooring action when the user pushes the movable furniture portion 2 inward to the position behind the closed end position E.

  The movable furniture part 2 exists in a closed end position and is held there by a lock tool 6. There, the locking element 44 of the receiving element 7 brakes the pin 15 of the engaging element 8 and the base element 43 of the receiving element 7 is fixed by the blocking mechanism 31. The user exerts an acting force on the front panel 3 in the closing direction SR of the movable furniture portion 2 until the movable furniture portion 2 reaches the track position shown in FIG.

  By the movement of the movable furniture part 2 to the release position, the blocking mechanism 31 formed by the slide guide track 45 is released, the base element 43 is rotated, and the pin 15 of the engagement element 8 is moved to the lock element 44 (FIG. 29c). ) And the movable furniture part 2 is moved to the open position by the discharge device as illustrated in FIG. 29c.

  Figures 30a to 30g show different positions of the receiving element 7 of the locking device 6 shown in the embodiment of Figure 20a when an erroneous operation by the user occurs. In this regard, an erroneous operation means that the user pushes in the movable furniture part 2 without releasing the locking action in advance with respect to the engagement element 8 and pulls out the movable furniture part 2 from the furniture frame 4.

  In this regard, FIG. 30a illustrates a starting position in which the movable furniture part 2 is in its closed end position E. FIG. If the movable furniture part 2 is pulled directly in the opening direction OR as illustrated in FIG. 30b, the locking element 44 of the receiving element 7 rotates or rotates around the rotation axis e by contacting the pin 15 of the engaging element 8. Rotate. In particular, in this embodiment, it rotates or rotates against the acting force of the holding device 33 that is a tension spring.

  In FIG. 30 c, the pin 15 of the engagement element 8 has left the receiving area 48 of the locking element 44. The locking element 44 is rotated back by the holding device 33. That is, the tension spring is released from the stress (FIG. 30d). Therefore, the movable furniture part 2 exists in the open position at this position, and the blocking mechanism 31 of the base element 43 is not released.

  If the movable furniture part 2 moves inside the furniture frame 4 in the closing direction SR as shown in FIG. 30e, the locking element 44 moves onto the pin 15 and the receiving element during further inner movement of the movable furniture part 2 7 is rotated as shown in FIG. 30f, the blocking mechanism 31 is released, the base element 43 is rotated to the release position of the pin 15 by the spring 46 from which the stress is released, and the movable furniture part 2 is It is moved to the open position (Fig. 30g) by the discharge device 18. The acting force storage means 19 is at least partially loaded by the inner movement of the moving furniture part 2.

  After an erroneous operation by the user, the open position in FIG. 30g corresponds to the open position in FIG. 29d after the normal open operation. In other words, in the case of an erroneous operation by the user, the overload safety mechanism 32 is activated in the first stage, and the movable furniture part 2 is movable in the second stage even if the lock device 6 is not unlocked. Before moving into the furniture frame 4 in the closing direction SR, it can be opened without damaging the members of the locking device 6, in particular the receiving element 7. When the receiving element 7 exerts pressure on the pin 15 of the engaging element 8, the blocking mechanism 31 acting on the locking device 6 is released in the third stage, and in the fourth stage the movable furniture part 2 is spring-loaded receiving element. 7 again leads to the open position. In other words, the movable furniture portion 2 has to be closed twice in order to return to the closed end position E after an erroneous operation by the user.

  Embodiments of the fixing device for braking the movable furniture part and the lockable discharge device for the movable furniture part are not to be construed in a limited way, they are the fixing device for the movable furniture part of the present invention or It is merely an individual example of the many possible embodiments that embody a lockable release device.
