A lateral snap-in pin projects from the rail close to the front end thereof, the snap-in pin being insertable, in the guiding direction, into a snap-in slit which is open towards the front and located on the front receiving fitting. A spring-loaded locking rocker secures the snap-in pin in the position thereof in the snap-in slit. The locking rocker can be displaced into a release position for releasing the snap-in tongue by actuating a release gear.

Description

The invention relates to a device for releasably receiving a laterally provided with two telescopic drawer slides in a furniture body, each of the two telescopic drawer slides has a cabinet rail which can be pushed at its rear end to a rear receiving fitting on the furniture body in the guide direction and at its front End can be latched to a front receiving fitting on the furniture body.

With drawers provided with telescopic drawer slides must be included in the designated drawer opening of a cabinet so that on the one hand unintentional complete withdrawal of the drawer is prevented, but on the other hand there is a solution to remove the drawer completely, if this is exceptionally desired, for example cleaning purposes.

In known devices of the type mentioned, the telescopic drawer guides are attached to the two lateral inner walls of the drawer opening of the furniture body, for example screwed. The drawer is detachably attached to its respective associated drawer rail. For this purpose, the pull-out rail engages at the rear end in a rear recess of the drawer. At the same time the pull-out rail is releasably secured to a mounted on the underside of the drawer coupling device.

In this case, it is necessary to make a machining on the trailing edge of the drawer to the required for hooking the drawer rail surfaces or to create recesses. In addition, the design effort for the coupling devices is relatively high and the height of this coupling device reduces the useful size of the drawer.

It is known ( US 2004/108 797 A1 ), a lateral guide rail to attach to a furniture drawer that laterally introduced from the furniture drawer head bolts inserted into keyhole-shaped holes of the guide rail and held by a spring-loaded guide pawl after a longitudinal displacement of the guide rail. However, this type of fixing makes it necessary that a lateral displacement must first be performed between the drawer and the guide rail to be attached thereto before the guide rail is displaced in the longitudinal direction into its locking position. It is therefore not possible to set a furniture drawer alone by inserting in the guide direction on the two side guide rails simultaneously. The known device is therefore not suitable for releasably receiving a drawer in a furniture body.

The object of the invention is therefore to provide a device for receiving a drawer of the type mentioned in such a way that with low construction costs a simple way is created to solve the drawer from the furniture body.

This object is achieved according to the invention that protrudes from the carcass rail near its front end, a locking element which in a forwardly open locking slot on the front receiving fitting in

Guide direction is introduced, that a spring-loaded locking rocker secures the locking element in its position in the locking slot and that the locking rocker is movable by actuation of a release lever in a releasing the locking element release position.

No additional work has to be done on the drawer to allow connection to the telescopic drawer slides. The insertion of the drawer is done in a simple manner in that the drawer is inserted from the front until the carcass rail is accommodated at its rear end on the rear receiving fitting and snaps into place at the front end on the front receiving fitting.

Unintentional pulling out of the telescopic drawer guides from the receiving fittings of the furniture body is prevented by the locking rocker. If the drawer is to be removed, the locking rocker can be moved by the release lever in a release position in which it releases the locking element, so that it can be pulled out of the locking slot forward. At the same time, the rear end of the carcass rail separates from the rear receiving fitting, without any coupling devices or the like having to be loosened for this purpose. Since the connection of the carcass rail at both the rear end and at the front end by simply pushing, can be achieved at the rear end by using an inclined surface in a simple manner that the telescopic drawer guide is raised at the end of the insertion process to them in their To bring operating position.

The locking element may be a latching tongue or a latching pin.

In a further development of the inventive concept it is provided that the blocking rocker can be pivoted while overcoming the force of a rocker spring between its locking position and its release position. The locking rocker is thus designed as a bistable element which is so long resiliently held in its blocking position as well as in its release position until it is pivoted back into the other position. For this purpose, it is appropriate that the Locking rocker is so far deflected by the latching tongue from its locking position that the latching tongue can be inserted into the locking slot, and that the locking rocker then returns by the rocker spring back into its blocking position. The locking rocker located in its blocking position is therefore resiliently overcome during insertion of the drawer by the latching tongue and then returns to its blocking position to secure the latching tongue.

According to a preferred embodiment of the invention it is provided that a rocker arm of the locking rocker protrudes in its release position in the movement path of the latching tongue and pivots the locking rocker by the engagement of the latching tongue on rocker arm in its blocking position. This ensures that the pivoted to remove the drawer in the release position locking rocker is pivoted back on withdrawal of the drawer by the latching tongue in the locked position, so that the locking rocker is during re-insertion of the drawer in its locked position. Thus, there is no risk that after inserting the drawer is forgotten to bring the locking rocker in its locked position, so that there is no danger that the drawer is unintentionally pulled out completely.

Further advantageous embodiments of the inventive concept are the subject of further subclaims.

In the Fig. 1-9 shown device is used for releasably receiving a drawer 1 in a furniture body 2 ( Fig. 4 ). At the two opposite lateral inner walls 3 of the furniture body each have a rear receiving fitting 4 and a front receiving fitting 5 is attached. The terms "front" and "rear" refer to the drawer 1 receiving opening in the furniture body.

The two receiving fittings 4 and 5 are screwed to the associated inner wall 3 and connected to each other by a spacer rail 6.

The drawer 1 carries on both sides in each case a telescopic drawer slide 7, each having a cabinet rail 8. At the rear end of each carcass rail 8 is a horizontal, widening rearwardly receiving slot 9 is formed, which is pushed from the front via an inwardly projecting horizontal tongue 10 of the rear receiving tab 4, when the drawer 1 is inserted from the front into the furniture body.

The upper edge of the receiving slot 9 merges rearwardly into a rising starting edge 9a.

Near the front end of each carcass rail 8 projects a lateral, horizontal latching tongue 11. At the front receiving fitting 5 a forwardly open locking slot 12 is formed, in which the latching tongue 11 is inserted from the front in the guide direction, at the same time the receiving slot 9 is pushed over the tongue 10.

Starting from the in Fig. 1 shown position enters the side rail 8 together with the drawer in the Fig. 2 shown end position. When inserting the drawer connected to the drawer outer rail 1a of the telescopic drawer slide slides on a horizontal guide leg 6a of the spacer rail 6 until the rising start edge 9a of the receiving slot 9 engages the tongue 10. As a result of the rising course of the leading edge 9a, the outer carcass rail 8 and at the same time attached to the drawer 1, wider pull-out rail 1a is raised. The drawer rail 1a, the in Fig. 1 indicated by dash-dotted line, thereby passes into the position shown there, raised by the spacer rail 6 position. This ensures that the movable pull-out rail 1a can move freely and without friction over the leg 6a of the spacer rail 6.

A two-armed locking rocker 13 is pivotally mounted on the front receiving fitting 5 about an axis 14 extending transversely to the guide direction. A release lever 15 is pivotally mounted about an axis 16 extending transversely to the guide direction on the front receiving fitting. The release lever 15 has a front side accessible to the touch surface 17.

A mounted on the front receiving fitting 5 on the axis 16 leg spring 18 forms in the execution Fig. 1 - 6 With its first spring leg 19, a rocker spring for the locking rocker 13. With its second spring leg 20, the leg spring 18 presses on the back of the sensing surface 17 to the release lever 15 in the counterclockwise direction Fig. 1 to keep in his rest position shown there.

The locking rocker 13 has on its side facing the first spring leg 19 two angular contact surfaces 21 and 22. The first spring leg 19 is located in the in Fig. 1 shown locking position of the locking rocker 13 on the contact surface 22 at. In the in Fig. 2 shown position of the locking rocker 13 is the first spring leg 19 on the other contact surface 21 at.

As in Fig. 1 shown, a rocker arm 23 of the locking rocker 13 protrudes in the blocking position ( Fig. 1 ) in the movement path of the latching tongue 11. When the latching tongue 11 from the in Fig. 1 shown position is moved back into the locking slot 12, the locking rocker 13 is deflected from its locked position by the locking tongue 11 so far that the locking tongue 11 can be inserted into the locking slot 12. The locking rocker 13 then returns by the action of the rocker spring formed by the spring arm 19 back into its blocking position and holds the locking tongue 11 in the locking slot 12th

The blocking rocker 13 is designed as a two-armed lever and has a further rocker arm 24. To the drawer off to release their locked position, one presses the front of the touch surface 17. The held by spring force in its rest position release lever 15 presses when actuated with an actuating lug 25 against the contact surface 22 of the locking rocker 13 and pivots in this way the locking rocker 13 against the force the spring leg 19 in its release position ( Fig. 3 ).

In this release position, which in the Fig. 2 and 3 is shown, the second rocker arm 24 of the locking rocker 13 protrudes in the release position in the path of movement of the latching tongue 11. If the now released drawer pulled out to the front, so the latching tongue 11 pivots by engagement on rocker arm 24, the locking rocker 13 in the Fig. 1 shown blocking position. The locking rocker 13 is thus overcoming the force of the rocker spring 19 between its blocking position ( Fig. 1 ) and their release order ( Fig. 2 ) pivotable.

Once the latching tongue 11 has overcome the rocker spring in the manner described, the drawer can be completely pulled out; it is no longer necessary to continue to press on the release lever 15. As soon as the drawer is reintroduced, the latching tongue 11 running onto the upper side of the rocker arm 23 pivots the rocker arm 23 down so far that it allows the latching tongue 11 to pass. However, the locking rocker 13 is thereby not yet pivoted into its release position as a second stable position, but returns to the blocking position as soon as the latching tongue 11 is passed over the rocker arm 23.

The in the Fig. 7 - 9 illustrated embodiment differs from the previously described embodiment essentially only in that the mounted on the front receiving fitting 5 release lever 15 is not spring-loaded. The blocking rocker 13 is supported by a rocker spring 27, which is supported on an abutment 26 on the front receiving fitting 5, both in its blocking position (FIG. Fig. 7 ) as well as in their release order ( Fig. 9 ) held. In the locked position ( Fig. 7 ) is the point of application 27a of the rocker spring 27 on the locking rocker 13 above the connecting line between the abutment 26 and the axis 14 of the locking rocker 13. This locking position is thus a first stable position of the locking rocker 13th

After the locking rocker has been pivoted against the force of the rocker spring 27 from this blocking position by actuating the release lever 15 from this blocking position counterclockwise ( Fig. 8 ), The point passes 27a of the rocker spring 27 to a position below the connecting line between the abutment 26 and the axis 14. At the same time the locking rocker sets 13 on an abutment _'28 on the front receiving fitting 5 at. The locking rocker 13 is then in a second stable position. In this release order ( Fig. 9 ), which the in Fig. 2 shown position, the locking tongue 11 in the already at Fig. 2 described manner are moved out of the locking slot 12 and pivots when passing the rocker arm 24, the locking rocker 13 back to the starting position according to Fig. 7 ,

The in the Fig. 10-14 shown, modified embodiment differs from the previous described embodiment already in that the locking element is not a laterally projecting latching tongue, but a locking pin 29 which projects down into the latching slot 12 which is formed in a horizontal plate 30 of the front receiving tab 5. The blocking rocker 13 'is in this case mounted pivotably about a vertical axis formed by a vertical pin 31 on the plate 30 and can against the force of a leg spring 18' from its rest position ( Fig. 12 ) are pivoted into their release position (13). The locking rocker 13 'has a locking arm 32, on which a securing hook 33 is formed, which engages in the locking position behind the locking pin 29 and this in the locked position ( Fig. 12 ) holds and secures.

In this position, the carcass rail 8 is fixed to a bent out of the rear receiving fitting 4 out receiving hook 34 with its rear end.

The locking rocker 13 'has a spaced apart from the securing arm 32 extending actuating arm 35 to which a sensing surface 17' is mounted to the locking rocker 13 'against the force of the leg spring 18' from their in Fig. 12 shown blocking position in their in Fig. 13 to swing shown release position. After the securing hook 33 has released the locking pin 29, the carcass rail 8 can be pulled out, the now released locking pin 29 moves along the locking slot 12.

The release of the locking pin 29 in the in Fig. 13 shown release position moving actuating arm 35 of the locking rocker 13 'can be locked in this release position. For this purpose, the actuating arm 35 on an end portion 36, on which an obliquely in the direction of the plate 30 bent spring tongue 37 is mounted. In the release position ( Fig. 13 ) of the locking rocker 13 'engages the tongue 37 in the locking slot 12 and holds the locking rocker 13' in the position shown.

From the extension 36 projects to the rear, ie the inner end of the locking slot 12 before a tab 38 which is angled obliquely away from the plate 30 and thus forms an inclined surface against which the locking pin 29 in its movement forward (to the right in Fig. 13 ) starts. As it moves along the detent slot 12, the detent pin 29 released from its detent position engages the beveled surface of the actuating arm 35 to disengage the actuating arm 35 from its locked position transverse to its pivoting plane. The tongue 37 leaves the locking slot 12 and the locking rocker 13 'returns from its in Fig. 13 shown position under the spring action of the leg spring 18 'in the in Fig. 14 shown position back. The actuating arm 35 of the locking rocker 13 'is thus in the release position ( Fig. 13 ) can be locked and released by the passing latching pin 29 from this locking position.

The safety hook 33 of the securing arm 32 has a front inclined surface 39 against which the locking pin 29 runs when it leaves the in Fig. 14 shown, released position to the left in the locking slot 12 is inserted. The safety hook 33 is on the insertion of the locking pin 29 against the spring force of the leg spring 18 'from the path of movement of the locking pin 29 swung out and is subsequently, when the safety hook 33 again in its holding position according to Fig. 14 returns, held by this in the locked position.

For removal of the drawer from the body of the furniture, the blocking rockers 13 'are pivoted by pressure on the sensing surfaces 17' on both side telescopic drawer guides, so that the two locking pins 29 are released. The two cabinet rails 8 can then be removed together with the drawer.

It is understood that the described device can be used in all types of drawer slides, which have a corresponding cabinet rail 8 on the outside. The details of the telescopic drawer guide are here without meaning and therefore omitted in the drawing. Usually these are ball or roller bearing guides.
