Description

The present invention relates to a locking system for pull-out furniture parts according to the preamble of claim 1 and a piece of furniture.

Generic locking systems for extendable furniture parts are known from the prior art. So will in the EP11839E3A1 an adapter for drawers and / or doors having furniture described which is equipped with a plurality of functional elements by which the opening and / or closing operation of the drawer or the door can be influenced. As a functional elements, for example, a fitting is called here, which causes the drawer is at least slightly opened when touched to allow intervention in the then existing gap between drawer front or door and the body of the piece of furniture, the release of such a fitting based on it in that the drawer is first slightly pressed in the closing direction and then released and opened by an ejection mechanism. Furthermore, a stop for a locking device is written, which causes a furniture with several superimposed drawers only one drawer can be opened.

A disadvantage of the conventional systems is that the combination of a locking system with an ejection device can lead to undesired blockages or entanglements of the locking system when the ejection device for one or more of the drawers is in the locked state of the locking system is triggered. A subsequent opening of the drawers by unlocking the central locking is not possible in this case, as jammed due to the triggered ejection process, one or more of the standing in operative connection with the locking pin pivot of one or more driver of the locking system in the locking bar.

Object of the present invention is therefore to provide a locking system with which the above-mentioned disadvantages are eliminated and in particular a reliable interaction of the various functional elements is ensured.

This object is achieved by a locking system for extendable furniture parts with the features of claim 1 and by a piece of furniture with the features of claim 15.

The locking system according to the invention has a locking strip for locking a plurality of superposed extendable furniture parts. At each of the extendable furniture parts, an ejection device is arranged, which in each case has a first carrier slidably mounted, which can be coupled with a first activator arranged on the furniture part. The ejection device is designed such that an actuation of an ejection process by a displacement of the first driver takes place counter to the ejection direction. On a housing on which the first driver is slidably disposed, a slidably mounted on the housing second driver is arranged, which is coupled to a arranged on the furniture part second activator and with a projecting from the locking bar side of the driver projecting pin the locking bar is in operative connection. According to the invention, at least one blocking unit is arranged on the locking strip which, when the locking strip is pushed into a locking position, blocks a displacement of the furniture parts against the ejection direction of the furniture parts and thus a triggering of an ejection operation by the ejection device.

With such a trained locking system movement of the furniture parts against the ejection direction is effectively prevented in a pushed into the locking position locking bar.

Advantageous embodiments of the invention are the subject of the dependent claims.

According to a particular embodiment of the invention, the blocking unit has a blocking element for each of the extendable furniture parts. This variant can be produced in a simple and cost-effective manner and can be easily integrated into existing locking systems.

According to a further embodiment variant, the blocking unit has a coupling strip and a coupling element connecting the coupling strip and the locking strip, wherein the blocking elements are fastened to the coupling strip. In a locking system designed in this way, a synchronization of the extendable furniture parts is made possible in such a way that when the locking bar is not completed after the ejection or extraction of one of the extendable furniture parts, the ejection devices of the other extendable furniture parts can not be triggered.

The blocking elements are preferably arranged so that it blocks a displacement of the second driver against the ejection direction of the furniture part in the locking position of the locking bar. By blocking this second driver blocking of a movement of the extendable furniture part is simultaneously effected against the ejection direction, since the attached to the pull-out furniture part second activator rests against the second driver.

Preferably, the blocking element is held by a spring element in the relaxed state in a position in which the second carrier in the housing against the ejection direction of the furniture part is displaceable. This ensures that in the unlocked state of the furniture or the locking bar, the ejection device is not blocked by the blocking element.

In the following description of the figures, terms such as top, bottom, left, right, front, back, etc. refer exclusively to the exemplary representation and position of the closing system and other parts selected in the respective figures. These terms are not intended to be limiting, that is to say, by different working positions or the mirror-symmetrical design or the like, these references may change.

In the FIGS. 1 to 6 is a first embodiment of a connection according to the closure system for extendable furniture parts shown. It is denoted by the reference numerals 1 a total of a via adapter 12,13 on a (not shown) furniture body of a furniture extendable fastened, especially designed as a drawer furniture called. The locking system is arranged on a side frame 11 of the furniture part 1.

The locking system has a locking bar 5 for locking a plurality of superimposed extendable furniture parts 1, via which the furniture parts 1 are coupled via the locking system with the locking strip 5 in such a furniture with several such extendable furniture parts 1 such that when ejecting or pulling out of the Furniture parts 1 causes a locking of the rest with this locking bar 5 coupled furniture parts 1.

The locking strip 5 is perpendicular to the extension direction x slidably mounted on the furniture body and preferably consists of a bar 51 which is bent at the edges so that within the bent edges 51 of the strip 51 a plurality of slidable in the direction of the longitudinal axis of the bar 51 sliding parts 52 einliegen. At the upper end of the bar 51, a vertically mounted on the bar 51 head piece 53 is attached to the side facing away from the bar 51 end a lock 54 is attached, with which the furniture is lockable, in which the bar 51 is lifted upwards and in this Position is fixed.

As in FIG. 2 can be seen, is attached to the adapter 13, a functional unit 2 with a housing 23. The functional unit 2 has an ejection device 21, which is connected to a driver 22, which is displaceable in a raceway 24 in the housing 23 in the ejection direction x of the drawer 1. Furthermore, a second driver 25 is mounted on the housing 23, which is mounted in a guide track 71 of the housing 23 slidably and pivotally. The guide track 71 runs parallel to the direction of movement of the furniture part 1 and is bent down at a front end in the extension direction x end. This front end of the guideway 71 serves as a self-locking position of the driver 25, in which the driver 25 is pivoted when the furniture part 1 is pulled out and remains stationary. Optionally, a tension spring (not shown here) is attached to the driver 25, which is fixed at its other end to a socket on the housing 23 such that the tension spring always pulls the second driver 25 in the direction of a position in which the driver 25 is located when the furniture part 1 is in its closed position in the Furniture is located. On the side facing away from the pull-out furniture part 1 of the driver 25 protrudes a pin 29 which is in operative connection with the locking bar 5.

In the closed position of the furniture part 1, as for example in FIG. 1 is shown, are both the first driver 22 and the second driver 25 in a position on the housing 23 in which they can be moved to trigger a discharge a piece against the ejector x, then to the discharge device 21 from the Furniture to be pushed out.

To trigger such a discharge operation, two activators 7, 8 are attached to the extendable furniture part 1, which can be coupled to the first driver 22 and the second driver 25.

As for activating the ejection process described above, the furniture part 1 must first be moved into the furniture by a few millimeters, the connection between the second driver 25 and the locking bar 5 is designed so that the furniture part 1 can protrude by a few millimeters from the furniture body of the furniture Without moving the locking bar 5 already in a position locking the other furniture parts. Is now pushed to lock the furniture, the locking bar 5 in its locking position, as in FIG. 4 Although the pull-out furniture parts 1 can no longer be pulled out of the furniture or ejected. A release of one or more of the ejection devices 21 by inserting one or more furniture parts 1 by a few millimeters into the furniture is still possible in this state and can during subsequent unlocking of the furniture part 1 by moving the locking bar 5 in the unlocked position to a jamming of the pins 29 lead in the locking bar 5.

To avoid this, at least one blocking unit 4 is arranged on the locking strip 5, which blocks a displacement of the furniture parts 1 against the ejection direction x of the furniture parts 1 and thus a triggering of an ejection process by the ejection device 21 when pushed into a locking position.

At the in FIGS. 1 to 6 shown embodiment, this blocking unit 4 consists of a blocking element 41 that is L-shaped and engages with an upper end 46 in a space between two adjacent sliding parts 52 of the locking bar 5 and the other end in the direction of the second driver 25 projecting nose 42nd having. The blocking element 41 is displaceable parallel to the longitudinal axis of the locking strip 5 in the housing 23 and is held in a preferred embodiment by a preferably designed as a compression spring spring element 45 in the relaxed state of the compression spring in a position in which the second driver 25 in the housing 23 against the ejection direction x of the furniture part 1 is displaceable.

Is the locking bar 5 from its open position to the closed position, as in FIG. 4 shown, lifted upwards in a closing direction z, the blocking element 41 is also moved over the engaging in the space between the sliding parts 52 of the locking bar 5 end 46 of the blocking element 41 in the housing 23 and touched in the final position reached with the nose 42 an edge 27 of the second driver 25, so that the second driver 25 is prevented from moving against the ejection direction x. Since the two drivers 22 and 25 controlling activators 7 and 8 fixed to the side frame 11 of the extendable furniture part 1 and the distance between the two activators 7, 8 corresponds to the distance of the drivers 22 and 25 to each other, the blockage of the second driver 25 leads against the ejection direction of the furniture part 1 to a total blockage of the furniture part 1 in said direction.

Trained as a compression spring spring element 45 is seated on the blocking element 41 on a parallel to the direction of displacement of the blocking part 4 aligned nose 44 and is received at its upper end in an upwardly closed cage 31 of the housing 23.

The FIGS. 7 to 14 show a second embodiment of a locking system according to the invention. With this embodiment, in addition to the blocking of the entire system by moving the locking bar 5 in the locking position and blocking of the furniture parts 1 with the Verriegelungsfeiste 5 is possible if one of the furniture parts 1 is in the pulled out of the furniture or pushed out position.

For this purpose, the blocking unit 6, a blocking element 62 for each of the extendable furniture parts 1 and a coupling strip 69, are secured to the blocking elements 62 and a coupling strip 69 and the locking bar 5 connecting coupling element 61 on. As especially good in the exploded view in FIG. 14 can be seen, each of the blocking elements 62 has a blocking head 63, the front edge 64 in the operative position touches the second driver 25 and blocks and on the coupling strip 69 side facing two pins 65 protrude, with which the blocking element 62 in mounting holes 68 in the coupling strip 69 is mountable. Adjoining the blocking head 63 is a control member 66 extending in the direction of the first driver 22 with an edge 67 bevelled in the rear, lower region, so that in an ejection process in which the first driver 22 of the ejection device 21 in the ejection direction x in the career 24 of the housing 23 is displaced in the ejection direction, the first driver 22 moves along the chamfered edge 67 of the blocking element 62 and thereby lifts the blocking element 62 upwards into the blocking position. By raising the blocking element 62 of the ejected furniture part 1, the coupling strip 69 is raised and thus moves the other attached to the coupling strip 69 blocking elements 62 of the other furniture parts 1. Thus, after ejecting or pulling out one of the furniture parts from the furniture no further ejection process be initiated at one of the other furniture parts 1.

The different positions of the blocking elements 62 in the open or closed locking system are in the FIGS. 10 to 13 shown, where FIG. 10 shows the state when located in an open position locking bar 5; the Figures 11 and 12 show the respective positions of the blocking elements when one of the ejection devices is triggered and FIG. 13 shows the position of the blocking elements in located in a closed position locking bar. 5

FIG. 15 shows a still further embodiment variant of a locking system according to the invention. The locking system shown here corresponds essentially to the in the FIGS. 7 to 14 shown variant with the difference that the respective blocking elements here only consist of the blocking head 63 ', which is attached to the coupling strip 69, so that in this variant only an overall blocking of the ejection devices is possible in the locking position located in the locking bar 5.

The Figures 16 and 17 show yet another embodiment of a locking system according to the invention, wherein in this variant instead of the locking bar with sliding in the bar 51 sliding parts 52 in the bar 51 'of the locking bar 5 a plurality of hook-shaped openings 52' are provided and the coupling element 61 in one of these hook-shaped openings 52 ' intervenes. The respective blocking heads 63 'are here corresponding to those in FIG. 15 formed embodiment shown.
