Description

TECHNICAL FIELD

[0001] The invention relates to a closing device for movable furniture parts, comprising a guide rail having a plurality of latching elements which are displaceably held along the guide rail, wherein each latching element comprises an upramp which can be contacted by an actuator attached to the movable furniture part and each latching element comprises a wall which can form a stop for the actuator to lock the movable furniture part with the actuator in a closed position, wherein the guide rail with the latching elements is movable between an anti-tilt position in which all actuators are arranged adjacent to the upramps on different latching elements and a latching position in which all actuators arranged in the latching position are arranged adjacent to the walls on different latching elements, and to a method for locking at least one movable furniture part to a furniture body with the closing device. BACKGROUND

[0002] DE 20 2009 000 050 U1 discloses a locking system for extendable furniture parts, wherein a locking lever having a plurality of sliding parts is provided. A movable furniture part acts on a driver which engages with one of the sliding parts in order to move the sliding part from an unlocked position to a locked position. The driver is slidably mounted on a housing and can be coupled with the movable furniture part over a short distance. The insertion of such a driver between the movable furniture part and the locking lever means an increase in manufacturing and assembly costs.

[0003] DE 10 2005 054 006 B4 discloses a pull-out safety device for extendable furniture elements, wherein a plurality of locking elements are movable along a linear guide. The locking elements are movable by means of a screw attached to the movable furniture element. The latches are strip-shaped and extend over almost the entire length of the furniture element. Here, due to the too great length, it is also disadvantageous in terms of construction. Furthermore, the tip of the lever can be easily damaged. SUMMARY

[0004] It is therefore an object of the present invention to provide a closing device for movable furniture parts and a method for locking at least one movable furniture part to a furniture body, which closing device is simple in construction and which enables an effective locking of the furniture parts in a closed position when one of the movable furniture parts is in an open position.

[0005] In the closing device according to the application, a plurality of locking elements are displaceably held along the guide rail, wherein each locking element comprises a rising ramp which can be contacted by an actuator attached to the movable furniture part. Each locking element further comprises a wall which can form a stop for the actuator to lock the movable furniture part with the actuator in the closed position. The guide rail with the locking elements can thus be moved between an anti-tip position in which all actuators are arranged adjacent to the rising ramps on the different locking elements and a locking position in which all actuators arranged in the closed position are arranged adjacent to the walls of the different locking elements. According to the application, in the anti-tip position, the guide rail can be displaced into the locking position when the actuators are moved against the rising ramps, in particular in the longitudinal direction of the guide rail, and then held in the locking position via a holding device. This makes it unnecessary to hold the locking elements via the actuators over the entire opening movement of the movable furniture part, but rather the actuators can move the guide rail into the locking position when moving against the rising ramps, thereby locking all other movable furniture parts in the closed position. The holding device holds the guide rail in the locking position until the furniture part in the open position is moved back into the closed position, thereby unlocking the guide rail by the holding device so that the guide rail is arranged again in the anti-tip position. This makes it unnecessary to provide a drive which is coupled to the movable furniture part over a certain distance between the movable furniture part and the locking elements. The actuators can be moved together with the movable furniture part, in particular the actuators can also be directly fixed on the movable furniture part. This reduces the number of required components of the closing device and enables a simple actuation, wherein the actuators can be compact.

[0006] Preferably, the holding device holds the guide rail in the locking position in a form-fit and / or force-fit manner, in particular in a clamping or latching manner. This enables the use of clamping elements or latching elements, such as latching webs, latching receptacles or latching protrusions, to easily secure the guide rail. Here, a magnetic holding device can also be used to achieve a virtually wear-free holding device.

[0007] In a preferred embodiment, the guide rail can be moved from the locking position into the anti-tip position via the actuators which are moved from the open position in the closing direction, whereby the actuators can then be moved along a guide ramp on the locking elements. Via the guide ramp, the locking elements can then release the guide rail from the locking position and move it into the anti-tip position. The guide ramp can be arranged on the side of the locking element opposite the rising ramp, wherein the term "opposite" refers to the movement direction of the actuators which are moved against the rising ramp during the movement of the movable furniture part in the opening direction and against the guide ramp during the opposite movement in the closing direction.

[0008] Preferably, the blocking elements are pre-tensioned by a force accumulator to the raised position. When the guide rail is moved from the blocking position to the anti-tilting position, at least some of the blocking elements are moved by means of an actuator which can be moved along a guide ramp against the force accumulator to the lowered position. The blocking elements can be pre-tensioned against an end stop on the guide rail via the force accumulator, so that the blocking elements are displaced along the guide rail via the actuator, regardless of whether the actuator is moved against the lifting ramp or the guide ramp. This allows at least some of the blocking elements to be displaced, forming a gap through which the actuator can then pass. After the actuator has disengaged from the blocking elements, the force accumulator can automatically move the blocking elements back to the closed position and close the gap created by the actuator again. The force accumulator can be supported on one side by a stop fixed to the guide rail and on the opposite side of one of the blocking elements or on a component between the blocking elements and the other end of the force accumulator. The force accumulator can be designed as a separate coil spring, a profile spring or a leaf spring or as an integral resilient element on the stop of the guide rail.

[0009] Preferably, a latching mechanism is provided, by means of which the guide rail is latched in the raised position. This makes it safer during operation. The latching mechanism can comprise, for example, a heart-shaped curve or a latching web which ensures that the guide rail is fixed in the raised blocking position.

[0010] Each blocking element preferably comprises a passage-shaped receptacle through which the actuator can pass without moving the blocking element. The passage-shaped receptacle can be used to move the closure device to a release position in which all the actuator is arranged adjacent to the passage-shaped receptacle so that all the movable furniture parts are also simultaneously moved in the opening direction. Such a release position is useful if the movable furniture parts are to be removed, for example during assembly, cleaning or moving.

[0011] The switching mechanism on the closure device, in particular the lock, can thus have three positions, namely a release position in which all the movable furniture parts can be moved in the opening direction, an anti-tilting position in which only one of the movable furniture parts can be moved in the opening direction at a time, and a locking position in which all the movable furniture parts are locked in the closed position.

[0012] Preferably, each actuator is designed as a pin which can be fixed to the movable furniture part. The pin can be fixed, for example, directly in a side wall or side frame of the movable furniture part. Alternatively, the movable furniture part and the actuator can also be fixed to one another via a holder or other component, for example via a pull-out guide.

[0013] Workshop equipment, practice equipment or laboratory equipment intended for the installation / use of movable drawers or push elements are to be understood exemplarily as furniture according to the application.

[0014] In the method for locking at least one movable furniture component to a furniture body according to the application, the first movable furniture component is first moved from the closed position in the opening direction, the actuator held on the furniture component is moved against the rising ramp of the blocking element, which is held on the guide rail, the blocking element moves the guide rail from the anti-tilt position to the locked position, in which all other movable furniture components, apart from the first furniture component, are locked in the closed position. The guide rail is then held in the locked position by the holding device, wherein the blocking element blocks the movement of at least one second furniture component, in particular all other components apart from the first furniture component, from the closed position in the opening direction. The holding device is able to hold the guide rail in the locked position in a form-fit and / or force-fit manner, in particular in a clamping or latching manner. In a next step, the first furniture component is moved back to the closed position, whereby the actuator on the first furniture component is moved against the guide ramp on the blocking element in order to release the guide rail from the locked position and move it to the anti-tilt position, in which the movable furniture components can be moved in the opening direction. The movement of the blocking element via the actuator for moving the guide rail from the anti-tilt position to the locked position and holding it in the locked position thus makes it possible to move the actuator in the opening region independently of the closing device, in particular away from the closing device. Only when the actuator is moved in the closing direction, shortly before the closed position, can the actuator move the guide rail via the blocking element again from the closed position to the anti-tilt position.

[0015] Preferably, at least some of the blocking elements are displaced along the guide rail against the force accumulator when the actuator on the first furniture component is moved against the rising ramp. Thereby, the blocking elements can form a gap between two adjacent blocking elements for the actuator to pass through. This movement of the blocking elements against the force accumulator can allow a temporary gap to be formed between two adjacent blocking elements for the actuator to pass through. During this movement, the guide rail is simultaneously moved into the blocking position and can be held in this position in a latching or clamping manner until the actuator is moved again in the closing direction.

[0016] Preferably, at least some of the blocking elements are displaced along the guide rail against the force accumulator when the actuator on the first furniture component is moved against the guide ramp, i.e. during the closing movement, in order to then displace the guide rail from the locked position to the anti-tilt position. A gap can thus be formed between two adjacent blocking elements for the actuator to pass through via the guide ramp, even when the actuator is returned from the open position in the closing direction. The latching or clamping fixation of the guide rail is released when the blocking elements are moved in order to move it to the anti-tilt position. BRIEF DESCRIPTION OF DRAWINGS

[0032] ​​​​The furniture 1 comprises a furniture body 2, on which pull-out guides 4 are fixed to opposite side walls. Each pull-out guide 4 comprises a fixed rail 5 and a movable runner 6, between which there can optionally be at least one central runner extending along the length of the drawer. A self-closing device 7 and / or a kick-out device are also combined with a damping system, which can be provided on the pull-out guide 4 in order to pull in or kick out the movable furniture part 3 in the form of a drawer.

[0033] On at least one side wall of the furniture body 2, a closure device 10 for the movable furniture part 3 is provided, by means of which it can be controlled whether the movable furniture part 3 can be moved via the pull-out guide 4 into an open position.

[0034] The closure device 10 comprises a rail 11, which is inserted into a recess 12 on the side wall of the furniture body 2 and can be moved in the vertical direction by means of a switching mechanism 15. As Figure 2 and Figure 3 shown, the rail 11 extends over a plurality of pull-out guides 4. Only two pull-out guides 4 are shown, although more than two pull-out guides 4 can also be installed on the side wall of the furniture body 2.

[0035] As shown in Figure 4 , the fixed rails 5 of the pull-out guides are not mounted directly on the side wall, but rather via an inserted spacer 13, in particular a plate. The spacer 13 has a recess in the area of the recess 12 for the rail 11. A large number of latching elements 20, for example made of plastic or metal, are movably held in the rail 11. The latching elements 20 are movable in the installed position and are prevented from being blocked by the fixed rails 5 via the spacer 13. It is also possible to dispense with the spacer 13 by making the recess 12 deeper or by using flat latching elements 20 in the area of the fixed rails. Furthermore, the recess 12 can also be dispensed with if the rail 11 is guided not in the recess 12 but rather via other guide elements, in particular linear bearings, in the area of the side wall of the furniture body 2.

[0036] The switching mechanism 15 comprises a rotatable knob, by means of which a connecting element 14 on a pin 19 mounted in an elongated hole 18 can be moved in the vertical direction. The rail 11 can be raised or lowered via the connecting element 14. A stop 30 is provided in the lower area of the rail 11 Figure 3 , which ensures that the latching elements 20 move together with the rail 11.

[0037] The pin-shaped actuators 16 are fixed directly or indirectly on each movable furniture part 3 and are engageable with the locking elements 20. The actuators 16 move together with the movable furniture parts 3. The actuators 16 are not assigned to each locking element 20, so that some of the locking elements 20 are designed only as spacers and optionally also as having a different shape from the locking elements 20, which can be coupled with the actuators.

[0038] A stop 30 is fixed in the lower region of the rail 11, on which a force accumulator 32 in the form of a spring is supported. The force accumulator 32 and the stop 30 are fixed by a clamp 31, which is fixed on a side wall of the furniture body 2. The stop 30 and the force accumulator 32 are movable relative to the clamp 31.

[0039] Figure 5A and Figure 5B The closing device 10 is shown in detail, which is arranged in the anti-tip (tipping protection) position of the furniture 1. In the anti-tip position, all actuators 16, which can be fixed on the movable furniture parts 3, for example on the side walls of the drawers, are located near the rising ramp 23 on the locking elements 20, each actuator 16 being assigned to a different locking element 20. In the anti-tip position, only one movable furniture part 3 at a time can be moved in the opening direction.

[0040] As Figure 6 is shown, when one of the movable furniture parts 3 is moved in the opening direction, the actuator 16 pushes the associated locking element 20 upward against the rising ramp 23, which is pushed against the web 17 fixed to the rail 11. This raises the rail 11, so that the lower stop 30 is displaced together with the force accumulator 32 relative to the clamp 31. The connecting element 14 is also moved along the pin 19 in the elongated hole 18. The locking element 20 arranged below the actuator 16 is pressed downward against the force accumulator 32, so that a gap is created between two adjacent locking elements 20, through which the actuator 16 can pass.

[0041] As Figure 7As shown, the actuator 16 can now be moved further in the opening direction. When the actuator 16 is no longer in contact with the blocking element 20, the force accumulator 32 pushes the lower blocking element 20 upwards to close the gap that previously existed between the two blocking elements 20 through which the actuator 16 passed. The guide rail 11 remains in the raised position because the connecting element 14 is held on the pin 19 by the two clamping webs 40. Additional latching protrusions 41 can be formed on the clamping webs 40 to latch to the pin 19 in the blocked position of the guide rail 11. In the raised, blocked position of the guide rail 11, the actuator 16 of the other movable furniture part 3 is located in the closed position next to the wall 22, which blocks the movement of the actuator 16 and thus also of the movable furniture part 3 connected thereto in the opening direction. Thus, all other movable furniture parts are locked in the closed position and only the furniture part 3 that is moved in the opening direction is freely movable.

[0042] If the movable furniture part 3 arranged in the opening direction is moved in the closing direction, the actuator 16 hits the guide ramp 25, which is arranged on the opposite side of the rising ramp 23 with respect to the movement direction of the actuator 16. In addition, the guide ramp 25 is inclined in the opposite direction, thus pushing the blocking elements 20 downwards instead of upwards as the rising ramp 23. The actuator 16 contacts the guide ramp 25 at the blocking elements 20 and presses all the blocking elements 20 below the actuator 16 downwards against the force accumulator 32 to form a gap through which the actuator 16 can pass. The downward movement of the blocking elements 20 causes the force accumulator 32 to push against the stop 30, which in turn pushes the guide rail 11 downwards, thus releasing the latches or clamps on the guide rail 11 that are held on the pin 19. This moves the guide rail 11 from the raised, blocked position to the lowered position.

[0043] Figure 9 The anti-tip position is shown again when the actuator 16 has moved the locking elements 20 downwards by moving against the force accumulator 32 and the guide rail 11 has been moved from the raised, blocked position to the lowered, anti-tip position. This position corresponds to Figure 5A .

[0044] Figure 10 Another position of the closing device 10 is shown, in which it is in the release position. Via the switching mechanism 15, the connecting element 14 has been raised to such an extent that all the actuators 16 are arranged adjacent to the passage-shaped receptacles 24 formed on each blocking element 20. Each actuator 16 can now easily be moved in the opening direction through the passage-shaped receptacle 24. This allows all the movable furniture parts 3 to be moved in the opening direction, for example in order to remove and disassemble the movable furniture parts 3.

[0045] Figure 11A closing device is shown with an improved connection element 14' in which elongated holes 18 are provided on opposite sides of the connection element 14' which is guided on a pin 19. A clamping web 40 is provided on each elongated hole 18, the clamping web having a latching protrusion 41. By guiding the connection element 14' on both sides, the guide rail 11 can be better guided and locked in the raised locking position. In the previous embodiment, only one pin 19 was provided on the connection element 14 to fix it in the raised position.

[0046] Figure 12 An improved design of the connection element 14' is shown in which a rack 71 is additionally provided in the central region which engages with a rotary damper 70 with a pinion. The rotary damper 70 is fixed in a recess 12 on the side wall of the furniture body 2. This allows the movement of the guide rail 11 relative to the furniture body to be slowed down. Alternatively or additionally, a latching device or other holding device can also be provided on the rotary damper 70 if required in order to fix the guide rail 11 in the raised position.

[0047] Figure 13 Another embodiment of the closing device 10 is shown with an improved connection element 14" which comprises 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 which can be connected to a lock or another component.

[0048] In Figure 14 and Figure 15 , the closing device 10 is shown with an additional latching mechanism 50 which is fixed to a holder 51 of the furniture body for latching the guide rail 11 in the raised, locked position. As shown in Figure 15 , the latching device 50 comprises a control element 52 which is connected to the connection element 14'. The control element 52 can be moved in a housing with a curved guide 53 and acts on a pestle 54 which is biased towards the guide rail 11 by a spring 55. The spring 55 is inserted on a housing 56 of the holder 51. The latching mechanism can latch the control element 52 to the curved guide 53, for example by configuring the curved guide as a heart-shaped bend with a latching receptacle into which a part of the control element 52 can be latched against the force of the spring 55. Other latching mechanisms can also be used to latch the guide rail 11.

[0049] In Figure 16 , the guide rail 11 is shown in the lower region 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 the integrally formed force accumulator 34 to support the locking element 20 which can be moved against the force accumulator 34 if one of the actuators is to be moved between the two locking elements 20.

[0050] In the embodiment shown, only two movable furniture parts 3 are provided as push elements, wherein each push element moves an actuator 16. Of course, the closure device 10 can be used for more than two movable furniture parts 3.

[0051] The closure device 10 is movable via a single switching mechanism 15 into at least one of three positions, i.e. at least one of a tilt-proof position, a locked position and / or a release position. It is also possible to switch the release position via a separate lever or actuating element, so that only the locked position and the tilt-proof position can be set via the switching mechanism 15.
