CLOSING DEVICE FOR MOVING FURNITURE PARTS AND METHOD FOR FASTENING AT LEAST ONE MOVING FURNITURE PART 7Qct7nn / C7n7 / e / YiAi FIELD OF THE INVENTION The present invention relates to a fastening device for moving furniture parts, comprising a guide rail with a plurality of locking elements that are held movably along the guide rail, where each locking element comprises an upward slope contactable by an activator attached to a moving furniture part and each locking element comprises a wall that can form a stop for the activator in order to lock the moving furniture part with the activator in a position closed, wherein the guide rail with the locking element can be moved between an anti-tip position, in which all the actuators are arranged adjacent to a rising slope in different locking elements, and a locking position, in which all activators arranged in the locking position are arranged adjacent to a wall in different locking elements, and a method for securing at least one movable furniture part to a furniture body with a clamping device. BACKGROUND OF THE INVENTION DE 20 2009 000 050 U1 describes a clamping system for extendable furniture parts, in which a clamping bar with a plurality of sliding parts is provided. A movable furniture part acts on an actuator that engages one of the sliding parts to move the sliding parts from a non-clamping position to a clamping position. The actuator is slidably mounted in a housing and can be engaged with a moving part of furniture over a short distance. The interposition of an actuator of this type between the moving part of furniture and the clamping bar means an increase in manufacturing and assembly costs. Document DE 10 2005 054 006 B4 describes a safety extraction device for extendable furniture elements in which a plurality of locking elements can be moved along a linear guide. The locking elements can be moved by means of a bolt that is attached to a movable furniture element. The latch is strip-shaped and extends over almost the entire length of the furniture element. Here, too, the construction effort is disadvantageous due to the great length. Additionally, the pointed ends of the bars can be easily damaged. BRIEF DESCRIPTION OF THE INVENTION Therefore, an object of the present invention is to provide a fastening device for moving furniture parts and a method for fastening at least one moving furniture part to a furniture body, which is simply constructed and allows effective fastening of the parts. furniture parts in a closed position when one of the movable furniture parts is in an open position. In the clamping device according to the invention, a plurality of locking elements are held movably along a guide rail, where each locking element comprises a rising slope contactable by an attached actuator. to a moving part of furniture. Each fastening element also comprises a wall that can form a stop for the activator in order to lock the moving furniture part with the activator in a closed position. The guide rail with the locking elements can thus be moved between an anti-tip position, in which all the actuators are arranged adjacent to a rising slope on different locking elements, and a locking position, in which all The actuators arranged in the closed position are arranged adjacent to a wall of different locking elements. According to the invention, in the anti-tip position, when an actuator moves against an upward slope, the guide rail can be moved to the locking position, in particular in the longitudinal direction of the guide rail, and then held in place. the locking position through a retaining device. This eliminates the need to retain the locking elements through the actuator throughout the opening movement of the movable furniture part, but instead the actuator can move the guide rail to a locking position when moving against the slope. upward, thus holding all other moving furniture parts in a closed position. The latch device retains the guide rail in this locking position until the furniture part that is in the open position is moved back to the closed position and the guide rail is thereby unlocked by the latch device. so that the guide rail is arranged again in the anti-tip position. This eliminates the need to provide an actuator between the moving furniture part and the locking elements, which engages the moving furniture part at a distance. The activator can be moved together with the moving furniture part, in particular the activator can also be fixed directly to the moving furniture part. This reduces the number of components required for the clamping device and allows for a simple actuation in which the actuator can be compact. Preferably, the retaining device retains the guide rail in the locking position in a clamping / form-fitting and / or clamping / force-fitting manner, in particular in a clamping or latching manner. This allows the guide rail to be easily secured using fasteners or latching elements, such as latching nets, latching receptacles or latching projections. The use of magnetic retaining means is also possible here to create an almost wear-free retaining device. zQctrnn / cznz / e / YiAi In a preferred embodiment, the guide rail can be moved from the locking position to the anti-tip position through an actuator that moves from the open position in the closing direction with the moving furniture part, whereby the Activator can be moved along a guide slope in a locking element. Through the guide slope, the locking element can then release the guide rail from the locking position and then move it to an anti-tilt position. The guide slope may be arranged on the opposite side of a locking element to the up slope, whereby the term opposite refers to the direction of movement of the actuator, which moves against the up slope during an upward movement. the movable furniture part in the opening direction and moves against the guide slope during an opposite movement in the closing direction. Preferably, the locking elements are deflected to a raised position by a force accumulator. When the guide rail is moved from the locked position to the anti-tip position, the actuator can move at least part of the locking elements to a lowered position against the force accumulator by means of an actuator that can be moved along. along the guide slope. The locking elements can be pretensioned against an end stop on the guide rail via the force accumulator, so that the locking elements move along the guide rail via the actuator, regardless of whether the actuator It moves against the uphill slope or the guide slope. This allows at least some of the locking elements to move, forming a gap through which the activator can then be passed. After the actuator is out of engagement with the locking elements, the force accumulator can automatically move the locking elements back to a closed position and close the gap created by the actuator again. The force accumulator may be supported on one side by a stop that is fixed to the guide rail and may be supported on the opposite side of one of the locking elements or on a component between the locking elements and the other end of the accumulator. of strength. The force accumulator can be designed as a separate spiral, form (biscuit jointer) or leaf spring or integrally as an elastic element in a guide rail stop. Preferably, a latching mechanism is provided by which the guide rail is latched in an elevated position. This leads to greater safety during operation. The latching mechanism may, for example, comprise a heart-shaped curve or latching web which ensures that the guide rail is secured in a raised locking position. Each locking element preferably comprises a channel-shaped receptacle through which an activator can be passed without moving the locking elements. This channel-shaped receptacle can be used to move the fastening device to a release position in which all the actuators are arranged adjacent to a channel-shaped receptacle so that all the moving furniture parts also move simultaneously in the opening direction. This release position is useful if the moving furniture parts are to be removed for disassembly, for example, during assembly, for cleaning or when moving the house. Therefore, a switching mechanism, in particular a lock, in the clamping device can have three positions, the release position, in which all moving furniture parts can move in the opening direction, the anti-tip position , in which only one of the moving furniture parts can move in the opening direction at a time, and a clamping position, in which all moving furniture parts are locked in the closed position. Preferably, each activator is designed as a pin that can be fixed to the moving furniture part. The pin can, for example, be fixed directly to a side wall or side frame of the movable furniture part. Alternatively, the movable furniture part and the actuator can also be fixed to each other through retainers or other components, for example, to through the extraction guide. The workshop, surgical / business or laboratory furniture for which the installation / use of mobile drawers or push elements is intended is understood by way of example as furniture according to the invention. In the method according to the invention for attaching at least one movable furniture part to the furniture body, a first movable furniture part is first moved from a closed position to an opening direction, an actuator held on the furniture part is moves against an upward slope in a locking element supported on a guide rail, the locking element moves the guide rail from an anti-tip position to a clamping position in which all other moving furniture parts except the first furniture part, are locked in the closed position. The guide rail is then held in the clamping position by a holding device, wherein the locking elements block a movement of at least a second furniture part, in particular all other parts except the first furniture part, from the closed position in the opening direction. The retaining device may hold the guide rail in the clamping position in a clamping / form-fitting and / or clamping / force-fitting manner, in particular in a clamping or latching manner. In a next step, the first furniture part is moved back to the closed position, whereby the actuator in the first furniture part is moved against a guide slope in a locking element in order to release the rail. guide from the clamping position and move it to the anti-tip position, in which a moving furniture part can move in the opening direction. The movement of the locking elements through 7Qct7nn / C7n7 / e / YiAi of the actuator is therefore used to move the guide rail from an anti-tip position to a clamping position and retain it there, making it possible to move the actuator in an opening area independently of, in particular at a distance from, the clamping device. Only when the actuator moves in the closing direction, shortly before the closed position, can the actuator move the guide rail back from the closed position to the anti-tilt position through a locking element. Preferably, when the actuator moves in the first furniture part against the upward slope, at least some of the locking elements move against a force accumulator along the guide rail. The locking elements can therefore form a gap to guide the actuator through two adjacent locking elements. This movement of the locking elements against the force accumulator may allow a brief gap to form between two adjacent locking elements for the activator to pass through. During this movement, the guide rail is simultaneously moved to a locking position and may be held there in a latching or locking manner until the actuator moves again in the closing direction. Preferably, when the actuator in the first furniture part moves against the guide slope, that is, during a closing movement, at least some of the locking elements move along the guide rail against a force accumulator. in order to then move the guide rail from the clamping position to the anti-tilt position. Even when the actuator is returned from the open position in the closing direction, a gap can thus be formed between two adjacent locking elements via the guide slope, through which the actuator can be passed. When the locking elements are moved, the latch or guide rail attachment is released to move it to the anti-tip position.

DETAILED DESCRIPTION OF THE INVENTION A furniture part 1 comprises a furniture body 2 in which extraction guides 4 are fixed to opposite side walls. Each extraction guide 4 comprises a stationary rail 5 and a movable slide 6, between which there may optionally be at least one central slide extending along the length of the drawer. An automatic closing device 7 and / or an ejection device, also in combination with damping systems, can be provided on the extraction guide 4 to pull or eject a moving furniture part 3 in the form of a drawer. A holding device 10 for moving furniture parts 3 is provided on at least one side wall of the furniture body 2, by means of which it can be controlled whether or not a moving furniture part 3 can be moved to an open position. through the extraction guide 4. The clamping device 10 comprises a guide rail 11 which is inserted into a slot 12 in the side wall of the furniture body 2 and which can be moved in the vertical direction by means of a switching mechanism 15. The guide rail 11 extends over several extraction guides 4, as shown in FIGURES 2 and 3. Only two extraction guides 4 are shown, although more than two extraction guides 4 can also be mounted on a side wall of the furniture body 2. As shown in FIGURE 4, the stationary rails 5 of the extraction guide are not mounted directly on the side wall, but through the interposition of a spacer 13, in particular a plate. The spacer 13 has a recess in the area of ​​a slot 12 for the guide rail 11. A large number of locking elements 20, which are made of plastic or metal, for example, are held displaceably in the guide rail. 11. The locking elements 20 can be moved in the mounted position, and the stationary rail 5 is prevented from locking the locking elements 20 through the spacers 13. It is also possible to dispense with the spacers 13 by making the slot 12 deeper or using flat locking elements 20 in the area of ​​the stationary rails. Furthermore, a slot 12 can also be dispensed with if the guide rail 11 is guided via other guide elements in the area of ​​the side wall of the furniture body 2, in particular linear bearings, instead of in a slot 12. . The switching mechanism 15 comprises a rotating knob by means of which a connecting element 14, which is mounted on a pin 19 in an elongated hole 18, can be moved in the vertical direction. The guide rail 11 can be raised or lowered through the connecting element 14. A stop 30 is provided in the lower area of ​​the guide rail 11 (FIGURE 3), which ensures that the locking elements 20 move together with the guide rail 11. An actuator in the form of a pin 16 is fixed directly or indirectly to each moving furniture part 3 and can be engaged with a locking element 20. The actuators 16 move together with the moving furniture part 3. An activator 16 is not assigned to each locking element 20, so that some of the locking elements 20 are only designed as spacers and can optionally also be designed with a different shape than the locking elements 20 that can be coupled with an activator. A stop 30 is attached to the guide rail 11 in the lower area, on which a spring-like force accumulator 32 rests. The force accumulator 32 and the stop 30 are secured by a clamp 31, which is fixed to the side wall of the furniture body 2. The stop 30 and the force accumulator 32 can be moved relative to the clamp 31. FIGURES 5A and 5B show the locking device 10 in detail, which is arranged in an anti-tip position (tip protection) for the furniture 1. In the anti-tip position, all the activators 16, which can be fixed to a moving part of furniture 3, for example to a side wall of a drawer, are located adjacent to a rising slope 23 in a locking element 20, each activator 16 being assigned to a different locking element 20. In the anti-tip position, only one of the 3 furniture moving parts can move in the opening direction at a time. When one of the moving furniture parts 3 moves in the opening direction, as shown in FIGURE 6, the activator 16 pushes the associated locking element 20 upwards against the rise slope 23, which is pushed against the net 17 which is fixed to the guide rail 11. This raises the guide rail 11 so that the lower stop 30 moves relative to the clamp 31 together with the force accumulator 32. The connecting element 14 also moves in the elongated hole 18 along the pin 19. The locking elements 20 zachnn / cznz / R / YiAi arranged below the activator 16 are pressed downwards against the force accumulator 32 so that a gap is created between two adjacent locking elements 20 through which the activator 16 can be passed. The actuator 16 can now be moved further in the opening direction, as shown in FIGURE 7. When the actuator 16 is no longer in contact with the locking elements 20, the force accumulator 32 pushes the lower locking elements 20 upward to close the previously existing gap between two locking elements 20 for the activator 16 to pass through. The guide rail 11 remains in the raised position because the connecting element 14 is held on the pin 19 by two fixing nets 40. Additional hooking projections 41 can be formed on the fixing nets 40 to engage the pin 19. in the locking position of the guide rail 11. In the raised locking position of the guide rail 11, the actuators 16 of the other moving furniture parts 3 are located in the closed position adjacent to a wall 22, which blocks a movement of the activator 16 and, therefore, also of the mobile furniture part 3 connected thereto in the opening direction. All other moving furniture parts are thus locked in the closed position and only the furniture part 3 that moves in the opening direction can move freely. If the movable furniture part 3 arranged in the opening direction moves in the closing direction, the activator 16 is located against a guide slope 25, which is arranged on the opposite side to the upward slope 23 in relation to the direction of movement of the activator 16. Furthermore, the guide slope 25 is inclined in the opposite direction, thus pushing the locking elements 20 downwards and not upwards like the rising slope 23. The activator 16 comes into contact with the guide bevel 25 on the locking element 20 and presses all locking elements 20 below the activator 16 downwards against the force accumulator 32 to form a gap through which the activator 16 can be passed. The movement downward of the locking elements 20 causes the force accumulator 32 to push against the stop 30, which correspondingly pushes the guide rail 11 downwards, thereby releasing the latch or clamp on the guide rail 11, which is held on pin 19. This moves guide rail 11 from the raised locking position to a lowered position. FIGURE 9 shows the anti-tip position that is reached again when the actuator 16 has moved the fastening elements 20 downward by moving against the force accumulator 32 and the guide rail 11 has moved from the raised locking position to the raised one. lowered anti-tip position. This position corresponds to FIGURE 5A. FIGURE 10 shows a further position of the clamping device 10 in which it is in a release position. Through the switching mechanism 15, the connection element 14 has been raised to such an extent that all the actuators 16 are arranged adjacent to a channel-shaped receptacle 24 formed in each locking element 20. Each actuator 16 can now be easily moved through the channel-shaped receptacle 24 in the opening direction. This allows all the moving furniture parts 3 to move in the opening direction, for example, to remove and dismantle the moving furniture parts 3. FIGURE 11 shows a fastening device with a modified connecting element 14', in which an elongated hole 18 is provided on opposite sides of the connecting element 14', which is guided on a pin 19. The fixing nets 40 are provided in each elongated hole 18, which have a latching projection 41. By guiding the connecting element 14' on both sides, the guide rail 11 can be better guided and clamped in the raised clamping position. In the above embodiment example, only one pin 19 was provided on the connecting member 14 to fix it in the raised position. FIGURE 12 shows a modified design of the connecting element 14', in which a grille 71 is additionally provided in a central area, which is in engagement with a rotary damper 70 with a pinion. The rotary damper 70 is fixed in the slot 12 in the side wall of the furniture body 2. This makes it possible to slow down a movement of the guide rail 11 with respect to the furniture body. Alternatively or additionally, latching devices or other retaining means may also be provided on the rotary damper 70 to secure the guide rail 11 in the raised position if required. FIGURE 13 shows another embodiment of the fastening device 10 with a modified connection element 14, comprising an elongated hole 18 with a pin 19 on one side, as described in the previous embodiments. On the opposite side, a connector 60 is formed that can be connected to a lock or other component. In FIGURES 14 and 15, the fastening device 10 is shown with an additional engagement mechanism 50 comprising a retainer 51 secured to the furniture body to engage the guide rail 11 in the raised locking position. As shown in FIGURE 15, the latching device 50 comprises a control element 52 that connects to the connection element 14'. The control element 52 is movable in a housing with a curve guide 53 and acts on a pylon 54 which is deflected towards the guide rail 11 by a spring 55. The spring 55 is inserted into a housing 56 of the retainer 51. The latching mechanism can engage the control element 52 to the curve guide 53, for example by configuring the curve guide as a heart curve with a latching receptacle to which a portion of the control element 52 can be latched against force. of the spring 55. Other engaging mechanisms can also be used to engage the guide rail 11. In FIGURE 16, the guide rail 11 is shown in a lower area in which a force accumulator 34 is used instead of a separate force accumulator 32, which is formed integrally with the web 33 of the stop 30. This allows that the integrally formed force accumulator 34 supports the clamping elements 20, which can move against the force accumulator 34 if one of the actuators is to move between two locking elements 20. In the example embodiment shown, only two moving furniture parts 3 are provided as push elements, each of which moves an actuator 16. Of course, it is possible to use the clamping device 10 for more than two moving furniture parts. 3. The clamping device 10 can be moved to at least one of three positions, namely the anti-tip position, the clamping position and / or the release position, through an individual switching mechanism 15. It is also possible to change the release position through a separate lever or actuating element, so that only the clamping position and the anti-tip position can be set through the switching mechanism 15.
