Description

VVO 2006/087048 PCT/)rP2006/000012 Device for Receiving a Di-awer The invention relates to a means for the releasable receptacle of a drawer which is laterally provided with two telescopic drawer buides in a body of a piece of furnitlu-e with each of the two telescopic guides coinprising a rail.

Drawers with telescopic drawer bruides must be accoiiin7odated in the designiated drawer opening of the body of a piece of furniture in a nlaiuier that ensures that, on the one hand, inadvertent complete pulling out of the drawer is prevented, and, on the other hand, it is possible to release the drawer so that it can be fully removed if this is desired, for example for cleaning purposes.

In known devices of drawers as described in the introduction the telescopic drawer guides are attached to, for example screwed to, the two lateral inside walls of the drawer opening of the body of the piece of furniture. The drawer is fastened to its respective guide rails and can be released. To accomplish this, the guide rail engages into a rear recess of the drawer at the rear end. At the same time the guide rail is fastened to a coupling device at the bottom of the drawer so that it can be released. To this end it is necessary to provide a means at the back edge of the drawer to provide the areas or recesses necessary so that the guide rail can engage. In addition, the design efforts for such coupling devices are relatively extensive, and the height of this coupling device reduces the useable space of the drawer.

The object of the invention therefore is to provide a device for receiving a drawer as defined in the introduction that allows for the removal of the drawer from the body of the piece of furniture without much design effort.

The object is attained in that the rail, on the reai- end thereof, can be pushed onto a rear receiving fitting on the body of the piece of fui-niture in the guiding direction, and on the fi-ont end thereof, can be engaged with a fi-ont receiving fitting on the body of the piece of fiurniture, that a lateral snap-in pin proj ects from the rail close to the fi-ont end thei-eof, said snap-in pin being inscrfable, ii1 the guiding dii-ection, into a snap-in slit which is open towards the front and located on the front receiving fitting. A spring-loaded locking rockei- secui-es the snap-in pin in the position thei-eof 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.

No additional woi-k on the drawer is neeessary to allow for the connection to the telescoping drawer guides. Inserting the drawer can be accomplished easily by inserting the drawer from the front until the rear end of the rail is in the rear receiving fitting and the front end engages with the front receiving fittint, The locking rocker pi-events an inadvertent pulling out of the telescopic drawer guides from the receiving fittings of the body of the piece of furniture. If the dT-awer is to be removed, the locking rocl:er can be displaced into a release position by actuating a release gear in which the locking means releases so that it can be pulled to the front and out of the snap-in slit. At the same time the 1-ear end of the 1-ail i-eleases froin the rear receiving fitting without requiring the release of any coupling devices or such. Since the coimection of the rail at the rear end as well as at the front end is accomplished by a simple pushing motion, a slanted area can be used at the rear end in a simple marmei- to ensure that the telescopic drawer guides are lifted into the operating position at the end of the pushing pi-ocess.

The locking means can be a snap-in tongue or a snap-in pin.

In a furtller development of the inventive thought the locking rocker pivots between its locking position and its release position by overconiing the force of a rocker spring. The locking rocker thus is a bi-stable means that is maintained in a spring position in its locking as well as in its release position until it is pivoted back into the respective other position. To this end it is practical if the locking rocker can be displaced from its locking position by the snap-in tongue until the snap-in tongue can be inserted into the snap-in slit and that the locking rocker then returns to its locking position.
The locking rocker in the locking position therefore is overcome in a resilient mamier due to the snap-in tongue when the drawer is inserted and then retui-ns to the locking position to secure the snap-in tongue.

Accoi-ding to a preferred embodiment of the invention a rocker ann of the locking rocker in the release position extends into the path of motion of the snap-in tongue and displaces the locking rocker due to the engagemelt of the snap-in tongue on the rocker arm in its locking position.
This nleans that the locking i-ocker that is displaced into the release position for removing the drawer is displaced back into the locking position by the snap-in tongue when the drawer is pulled out so that the locking rocker is in the locking position when the drawer is inserted again. This ensures that one does not forget to retuni the locking rocker back into the locking position after the drawer is inserted again and that thei-e is no possibility of inadvertently removing the drawer completely.

Other advantageous embodiments of the inventive thougllt al-e the subject of additional dependent claiins.

The device shown in Fig. 1- 9 is used to provide a releasable i-eceptacle of a drawer I in the body of a furniture piece 2(Fig. 4). A rear receiving fitting 4 and a fi-ont receiving fitting 5 ai-e arranged on the two opposite lateral inside walls 3 of the body of the furnitui-e piece. The terms "front" and "rear" refer to the opening in the body of the furniture piece that acconunodates the drawer 1.

The two receiving fittings 4 and 5 are screwed to the respective inside wall 3 and are connected by a spacer rail 6.

The drawer I comprises a telescopic drawel- guide 7 on each side with each having ai-ail S. Arranged at the rear end of each i-ail 8 is a lioi-izontal i-eceiving slit 9 that expands towards the rear and that can be pushed from the fi-ont aci-oss a hoi-izontal ton~a.ie 10 of the rear receiving fitting 4 protruding to the inside when the drawer is pushed into the body of the piece of furniture from the front. The upper edge of the receiving slit 9 transitions nito an inclining stop edge (9a) towards the rear.

A lateral, llorizontal snap-in tongue 11 protrudes near the front end of each rail 8. A snap-in slit 12, which is open towards the front, is located on the front receiving fitting 5, into which the snap-in tongue 11 can be inserted from the fi-ont in the guiding direction, wlule the receiving slit 9 simultaneously is pushed over the tongue 10.

Based on the position shown in Fig. 1, the lateral rail 8 together with the drawer reaches the end position shown in Fig. 2. When the drawer is inserted, the outside rail I a of the telescopic drawer guide that is cormected to the drawer glides on a horizontal guide leg 6a of the spacer rai16 until the inclining stop edge 9a of the receiving slit 9 engages with the tongue 10. Due to the incline of the stop edge 9a, the outside rail 8 and at the same time the wider drawer guide la that is attached to the drawer 1 is lifted. The drawer guide 1 a that is indicated with a dash-dotted line in Fig. 1 thus reaches the indicated position above the spacer rail 6. This ensures that the mobile drawer guide 1 a moves freely and without friction across the leg 6a of the spacer rail 6.

A two-armed locking rocker 13 is arranged in a pivoting matuzer on the fi=ont receiving fitting 5 around an axle 14 that extends latei-ally to the guiding dii-ection. A release gear 5 is airanged in a pivoting nZanner around an axle 16 that extends laterally to the guiding direction. The release gear 15 has a touch ai-ea 17 that is accessible from the front.

In the embodiment according to Fig. 1- 6, a leg spring 18 arranged on the axis 16 on the front receiving fitting 5 provides a rocker spring for the locking rocker 13 comprised of its first spring leg 19. With its second spring leg 20, the leg spring 18 pushes onto the back side of the touch area 17 to keep the r-elease -ear 15 in counterclockwise du-ection in Fig. I in its resting position shown in the Figure.

On the side that faces the spring leg 19, the locking rocker 13 has two stop faces 21 and 22 that are at an angle in relation to each other. The first spring leg 19 i-ests in the locking position of the locking rocker 13 on the stop face 22 as shown in Fig. 1. In the position of the locldng i-ockei-13 shown in Fig. 2, the fi-st spring leg 19 rests against the othei- stop face 21.

As is shown in Fig. 1, a rockel- arm 23 of the locking i-ockei- 13 in locking position (Fig. 1) eatends into the path of rnotion of the snap-in tongue 1 l. When the snap-in tongue 11 is moved froln the position shown in Fig. I backward into the snap-in slit 12, the locking i-ocker 13 is deflected fi-oin its locking position by the snap-in tongue 1 1 until the snap-in tongue 1 l can be inserLed into the snap-in slit 12. The locking rocker 13 subsequently retums into its locking position due to the effect of the rocker spring comprised of the spring ann 19 and retains the snap-in tongue I 1 in the snap-in slit 12.

The locking rocker is comprised of a two-armed lever and has another rocker ann 24. In order to release the drawer from its locked position, one pushes on the touch area 17 from the front. The release gear 15 that is retained in its resting position by the spring force pushes against the stop face 22 of the locking rocker 13 with an actuation nose 25 when actuated and in this manner displaces the locking rocker 13 into its release position (Fig. 3) against the force of the spring leg 19.

In this release position that is shown in Fig. 2 and Fig. 3, the second rocker arn124 of the locking rocker 13 in release position extends into the path of motion of the snap-in tongue 11. If the drawer, which now is released, is pulled out towards the front, the snap-in tongue 11 displaces the locking rocker 13 into the locking position shown in Fig. 1 by engaging with the rocker ann 24. Thus the locking ai7n 13 can be displaced between its locking position (Fig. 1) and its i-elease position (Fig. 2) while ovei-coming the force of the rocker spring 19.

As soon as the snap-in tongue 11 overcomes the locking spi-ing in the described inannei-, the drawer can be removed coinpletely and it is no longer necessary to push down the release gear 15. As soon as the drawer is inserted again, the snap-in tonbrue 1 I that i-ides on the upper side of the rocker arin 23 pivots the rockei- ai7n 23 down until it allows the snap-in tongue I 1 to pass. However, this does not yet put the locking rockei- 13 into its i-elease position as a second stable position, but rather it returns to the locking position as soon as the snap-in tongue I 1 has passed the i-ocker arnl 23.

The embodiment shown in Fig. 7 - 9 is different from the embodiment described above substantially only in that the release gear 15 arranged on the fi-ont receiving fitting 5 is not spring loaded. The locking rocker 13 is retained in its locldng position (Fig. 7) as well as its release position (Fig. 9) by a rocker spring 27 that rests against an abutment 26 on the fi-ont receiving fitting 5. In the locking positions (Fig. 7), the point of impact 27a of the i-ocker spring 27 is on the locking rocker I 3 above the comlecting line between the abutment 26 and the axis 14 of the locking rocker 13. This locking position thus is a iii-st stable position of the locking rocker 13.

After the locking rocker is displaced in a counterclockwise dii-ection against the force of the rocker spring 27 frorn this locking position by ineans of actuating the release gear 15 from this locking position (Fig. 8), the point of impact 27a of the rocker spring 27 reaches a position below the coiu7ecting line between the abutment 26 and the axis 14. At the sanle time the locking rocker 13 rests against an abutment 28 on the front receiving fitting 5. The locldng rocker 13 now is in a second stable position. In this release position (Fig. 9) that con-esponds to the position shown in Fig. 2, the snap-in tongue 11 can be moved out from the snap-in slit 12 as already described and displaces the locking i-ocker 13 back into the starting position according to Fig. 7 when it passes the rocker ann 24.

The modified exenzplary embodiment shown in Fig. 10 - 14 is different from the described einbodiment in that the snap-in means is not a laterally protruding snap-in tongue but rather a snap-in pin 29 that protrudes downward into the snap-in slit 12 that is arranged in a horizontal plate 30 of the rail 8. The loclcing rocker 13' is an-anged in a pivoting mam7er around a vertical axis comprised of a vertical pin 31 on the plate 30 and can be pivoted from its snap-in position (Fig. 12) into its release position (13) against the force of a leg spring 18'. The locking rocker 13' has a locking arm 32 on which a stop hook 33 is arranged that extends behind the snap-in pin 29 in the snap-in position and retains and secures it in the snap-in position (Fig. 12).

In this position the rear end of the rail 8 is fastened to a receiving hook 34 that is bent at a right angle fi-om the i-ear receiving fitting 4.

The locking rockei- 13' has an actuating ann 35 that is arranged at a distance to the locking ann 32, on which a touch ai-ea 17' is arranged, around which the locking rocker 13' pivots against the force of the leg spring I 8' fi-oin its locking position shown in Fig. 12 into its i-elease position shown in Fig. 13. Afler the stop liook 33 releases the snap-in pin 29, the rail 8 can be pulled out with tlie now released snap-in pin 29 moving along the snap-in slit 12.

The actuation ann 35 of the locking rocker 13' that now is inoved into the release position shown in Fig.
13 in order to release the snap-in pin 29 can be fixed in this release position.

To this end, the actuation arm 35 comprises a final section 36 on which a spring tongue 37 is arranged that is bent laterally in relation to the plate 30. In the release position (Fig. 13) of the locking rocker 13', the tongue 37 snaps into the snap-in slit 12 and i-etains the locking rocker 13' in the position that is shown.

From the extension 36 a tab 38 protrudes to the rear, i.e. towards the inside end of the snap-in slit 12 that is angled diagonally away from the plate 30 and thus forms a diagonal area against which the snap-in pin 29 runs during its forward motion (towards the right in Fig. 13). During its motion along the snap-in slit 12, the snap-in pin 29 that is released from its snap-in position engages with the diagonal area of the actuation ann 35 to release the actuating ann 35 from its fixed position diagonal to its pivot plane. The tongue 371eaves the snap-in slit 12 and the locking rocker 13' returns from its position shown in Fig. 13 into the position shown in Fig. 14 due to the spring effect of the leg spring 18'. The actuating ann 35 of the locking rocker 13' thus can be fixed in the release position (Fig. 13) and can be released from this fixed position when the snap-in pin 29 moves past.

The stop hook 33 of the locking ann 32 has a front diagonal area 39 against which the snap-in pin 29 runs when it is inserted to the left into the snap-in slit 12 from the released position shown in Fig. 14. When the snap-in pin 29 is inserted, the stop hook 33 can be displaced against the spring force of the leg spring 18' from the path of motion of the snap-in pin 29 and is retained by it in the snap-in position when the stop hook 33 returns into its retaining position aecording to Fig. 14.

To remove the drawer from the body of the funliture piece, the locking rockers 13' are displaced by puslling on the touch areas 17' on both latei-ally provided telescopic drawer guides so that the two snap-in pins 29 ai-e released. The two i-ails 8 now can be removed together with the d1-awer.

It is undei-stood that the device described above can be used in any kind of drawer guides that have a corresponding rail 8 on the outside. The details of the telescopic drawer guides al-e not of iinportance and tl-ierefore are not included in the drawings. Usually these are ball bearing oi- i-oller beai-ing guides.
