Description

Drawer rail for a drawer pull-out guide

The present invention relates to a drawer rail for a drawer pull-out guide, comprising:

a first rail to be fastened or fixed to a drawer,

a second rail to be arranged or arranged on a carcass rail or middle rail of a drawer pull-out guide,

- Wherein the first rail and the second rail are connectable by pushing together, wherein the first rail and the second rail are locked together in a connected state by at least one locking element, wherein the locking element is biased by a force of a force accumulator in the direction of a locking position.

Furthermore, the invention relates to a drawer extension with at least one drawer rail of the type to be described and a piece of furniture with a furniture body and a relative to the furniture body movably mounted drawer. Furthermore, the invention relates to a method for connecting a first rail to a second rail of a drawer rail on a drawer extension guide.

In DE 198 28 718 A1 discloses a locking device for releasably securing drawers to an extendable guide rail of a drawer pull-out guide, wherein the drawer is placed during assembly on the guide rail and as long as moved backwards until a loaded by a spring locking latch automatically into a Latching opening of the drawer engages. This ensures that the drawer is mounted immovably relative to the guide rail in a normal operation. The latching bolt is mounted linearly displaceable in the mounting position in a vertical direction and has at the lower end of a handle, wherein the lock between the drawer and the guide rail is releasable by a downward manual pulling movement on the locking latch. The disadvantage of this is that the space of the drawer extension due to the downwardly projecting locking latch is to be sized relatively large. DE 20 2013 100 013 U1 shows a drawer pull-out guide with a cabinet rail to be fastened to a furniture carcass, a drawer rail to be fastened to a drawer, and a middle rail which is movably mounted between the carcass rail and the drawer rail. At the front end of the drawer rail, an elastic pressing element in the form of a spring tongue is arranged, which is bendable when pushing the drawer on the drawer rail upwards and then locks the drawer relative to the drawer rail. The disadvantage of this is that the spring tongue is visible even when mounted drawer.

In AT 518 232 A1 there is a drawer arrangement with a

Drawer pull-out guide and shown with a drawer side wall, wherein a support rail with the drawer side wall is firmly connected. At the front end of the support rail of the drawer side wall, an actuating element is pivotally mounted, which is detachably lockable when sliding the drawer side wall with the drawer rail of the drawer extension. The disadvantage of this is that each drawer must be equipped to lock with the drawer extension with an actuator.

Object of the present invention is to provide a drawer rail of the type mentioned above while avoiding the disadvantages discussed above.

This is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent claims.

According to the invention, it is provided that the locking element is arranged on the second rail and, upon pushing the first rail on the second rail, starting from the locking position against the force of the energy storage device about an axis horizontally extending in mounting position in the direction of the carcass rail or the middle rail of the drawer extension is pivotable in a release position.

Thus, the locking element is pivotally mounted in a mounting position of the drawer rail about a horizontally extending axis, so that the drawer in the Mounting on the drawer extension guide can be placed on the first rail and moved backwards until the locking element by the weight of the drawer against the force of the energy storage downwards towards the release position evades and the drawer in a continued insertion movement by the force of the energy storage solvable is lockable.

The feature of the locking element, which is mounted pivotably in the mounting position of the drawer rail about a horizontally extending axis, starting from the aforementioned DE 198 28 718 A1 also no obvious measure, because the downwardly projecting handle according to DE 198 28 718 A1 a essential technical feature for releasing the lock between the drawer and the guide rail.

One advantage of the invention is that the first rail arranged on the drawer does not require a suspension lift in a vertical direction when pushed onto the second rail. The drawer can therefore be pushed during assembly in a horizontally extending plane on the second rail until the locking element first dodge down and then snap up again by the force of the energy storage and thus automatically locks the drawer relative to the second rail. Thus, no space required in the height direction for locking, which proves to be particularly advantageous if the drawer is to be mounted in a furniture carcass immediately below a countertop and consequently only a very small distance between the drawer and the underside of the worktop is present.

The locking element is mounted on the second rail. For the purpose of improved accessibility, it may be favorable if the locking element is movably mounted on a front end region of the second rail.

In one embodiment, it may be provided that the locking element is passed through an opening of the second rail. This results in a compact and visually inconspicuous design, because the locking element is arranged for the most part within a rail cross-section of a rail and only provided for locking part of the locking element the second rail protrudes. It is preferably provided that the opening is arranged on a, preferably in mounting position horizontally extending, central web of the second rail.

The at least one locking element and the energy accumulator may be formed integrally together or may be designed as separate components. In the one-piece design of the energy storage can be formed by a material elasticity of a plastic part. To increase the spring force, however, it may be favorable if the energy accumulator comprises a separate from the locking element mechanical spring element (for example, a leaf spring made of steel).

The drawer extension guide according to the invention has a cabinet rail to be fastened to a furniture carcass and a drawer rail of the type in question, wherein the drawer rail is mounted displaceably relative to the carcass rail. In order to enable a full extension of the drawer relative to the front side of the furniture body, an additional center rail can be provided, which is displaceably mounted between the carcass rail and the drawer rail.

The inventive method for connecting a first rail to a second rail of a drawer rail is characterized in that

in a first method step, the first rail to be fastened or fastened to a drawer is placed on the second rail to be arranged or arranged on a carcass rail or middle rail of a drawer extension guide,

in a second method step, the first rail is pushed onto the second rail,

- In a third step, the locking element of the second rail is pivoted against the force of the energy storage to a horizontal in mounting position axis in the direction of the carcass rail or the middle rail of the drawer extension in a release position, and

- In a fourth method step, the locking element is moved by the force of the energy storage in a locking position, whereby the two rails are locked together. Further details and advantages of the present invention will be explained with reference to the embodiment shown in the figures.

1 shows a piece of furniture 1 with a cabinet-shaped furniture body 2, wherein drawers 3 are movably mounted via drawer pull-out guides 4 relative to the furniture body 2 are. The drawers 3 have a front panel 5, a drawer bottom 6, side walls 7 and a rear wall 8. The drawer extension guides 4 comprise a carcass rail 9, which is to be fastened to the furniture body 2 via fastening sections 10a, 10b and at least one drawer rail 11 displaceable relative to the carcass rail 9. The drawer rail 11 is formed in at least two parts and comprises a drawer 3 to be fastened or fastened In order to enable a full extension of the drawer 3 relative to the furniture body 2, an additional center rail 14 may be provided, which between the carcass rail 9 and the Store rail 11 is slidably mounted. The drawers 3 are mounted on the drawer pull-out guides 4 by first placing the drawer 3 on the second rails 13 located opposite the furniture carcass 2. Subsequently, the first rails 12 fastened to the drawer 3 are pushed onto the second rails 13 in the longitudinal direction (L) until the first and second rails 12, 13 are automatically activated by at least one locking element 21 pivotable about a horizontally extending axis 26 (FIG be locked together so that the first and second rails 12, 13 are arranged fixed relative to each other in the connected state.

FIG. 2a shows the drawer 3 to be fastened to the drawer pull-out guide 4 in a perspective view, a side wall 7 of the drawer 3 being hidden for reasons of improved clarity. Visible is arranged on the drawer 3 first rail 12 of the drawer rail 11, wherein in the front end region of the first rail 12, a first mounting adapter 16 for fixing the front panel 5 and the rear end of the first rail 12, a second mounting adapter 17 for fixing the rear wall 8 is arranged is. The first rail 12 has two side legs 12a running in the longitudinal direction (L) and spaced substantially parallel to one another, wherein at least one spring means 18 in the form of an elastically bendable spring tongue is arranged on one of the side legs 12a. The spring means 18 of the first rail 12 is in the connected state of the rails 12, 13 on the second rail 13, so that transverse movements of the rails 12, 13 are limited to each other. In the embodiment shown, two longitudinally spaced (L) spring means are on the first rail 12 18, 19 provided. At the rear end of the second rail 13, a hook 15 is arranged, which limits the Aufschiebeweg the first rail 12 relative to the second rail 13 in the sliding direction 20 and which stabilizes the rear end portion of the drawer 3 in a direction transverse to the longitudinal direction (L) in the mounted state , The carcass rail 9 of the drawer extension guide 4 is mounted on the furniture body 2 via the attachment sections 10a, 10b, the second rail 13 of the drawer rail 11 and the center rail 14 being displaceably mounted relative to the stationary carcass rail 9. The drawer 3 is mounted on the second rail 13 by the first rails 12 connected to the side walls 7 of the drawer 3 are pushed onto the second rails 13 of the drawer extension guides 4 in the sliding direction 20.

2b shows the connected state of the drawer 3 on the drawer extension guide 4, wherein the second rail 13 is received for the most part within a cross-sectionally U-shaped profile of the first rail 12 and wherein the rails 12, 13 by the spring means 18, 19 in a direction transverse to the longitudinal direction (L) extending direction, preferably in a laterally to the longitudinal direction (L) of the rails 12, 13 extending direction, are arranged without play to each other.

3a shows the drawer pull-out guide 4 with the carcass rail 9, the middle rail 14 and the second rail 13, which is to be connected to the first rail 12 of the drawer 3.

Fig. 3b shows the circled in Fig. 3a area in an enlarged view, in which the movably mounted locking element 21 for releasably locking the rails 12, 13 is shown. The locking element 21 is arranged at the front end region of the second rail 13 and passed through an opening 22 of the second rail 13. The locking element 21 is pivotable when sliding the first rail 12 on the second rail 13, starting from the locking position against the force of a force accumulator 25 about a horizontally extending in mounting position 26 in the direction of the carcass rail 9 or the middle rail 14 of the drawer extension guide 4 in a release position. 3c shows the second rail 13 of the drawer extension guide 4 and the first rail 12 to be connected to the side wall 4 in a perspective view. The second rail 13 has two, preferably mutually parallel, side legs 13a and the two side legs 13a connecting central web 13c. The central web 13c of the second rail 13 has a, for example rectangular, opening 22 for the passage of the movable locking element 21. The locking element 21 is arranged fixed in a longitudinal direction (L) and movably mounted in a direction approximately perpendicular to the central web 13c of the second rail 13. In the exemplary embodiment shown, the locking element 21 is integrally formed together with a front-side functional head 23, which is received for the most part within the rail cross-section of the second rail 13. The first rail 12 also has two side legs 12a, preferably running parallel to one another, and a central web 12c connecting the two side legs 12a. Moreover, the first rail 12 is provided with a support leg 12d for the drawer bottom 6. The first rail 12, preferably the central web 12c, has at least one downwardly projecting projection 24a, which is detachably lockable with the locking element 21 of the second rail 13. In the exemplary embodiment shown, two projections 24a, 24b spaced apart in the longitudinal direction (L) are provided, the locking element 21 being in a pre-locking position of the first and second rails 12, 13 with the first projection 24a and in a connected state of the first and second rails 12, 13 with the second projection 24 b is releasably lockable. The projections 24a, 24b may be bent downwardly from the central web 12c of the first rail 12. Alternatively, the projections 24a, 24b may be embodied as components separate from the first rail 12, which are fastened to the first rail 12.

4a-4d show the sliding of the first rail 12 on the second rail 13 in longitudinal sections. Two projections 24a, 24b spaced apart from one another in the longitudinal direction (L) are arranged on the first rail 12 and protrude downward from the central web 12c of the first rail 12. At the front end of the second rail 13, the functional head 23 is arranged with the locking element 21, which is mounted in the mounting position about a horizontal axis 26 pivotally. to Assembling the drawer 3 on the drawer extension guide 4, the first rail 12 connected to the drawer 3 is placed on the front end region of the second rail 13 preassembled on the furniture body 2 and displaced in the sliding direction 20, the middle web 12c of the first rail 12 and the center web 13c of the second rail 13 first slide against each other. As a result of continued movement of the first rail 12 in the sliding direction 20, the front edge of the first rail 12 abuts against the locking element 21 of the second rail 13 (FIG. 4b). By a further movement of the first rail 12 in the sliding direction 20, the locking element 21 of the second rail 13 is pivoted against the force of a force accumulator 25 about the horizontal axis 26 (FIG. 4c). By pushing the first projection 24a of the first rail 12 on the central web 13c of the second rail 13, the first rail 12 is raised to form a gap 27 of the second rail 13, whereby the charged energy storage 25 relaxes and the locking element 21 about the axis 26 snaps back upwards (Fig. 4d). This has the advantage that the two rails 12, 13 do not come into contact with each other via their flat center webs 12c and 13c when they are pushed on, but only via the projections 24a, 24b. In this way, the frictional resistance and any unpleasant noise developments when sliding the rails 12, 13 are reduced so that the sliding of the rails 12, 13 is smooth and quiet.

5a-5d show a continued movement of the first rail 12 in the sliding direction 20, wherein now both projections 24a, 24b slide to form the gap 27 between the central webs 12c, 13c along the second rail 13 (Figure 4e). The first projection 24a of the first rail 12 moves the locking element 21 about the horizontal axis 26 against the force of the force accumulator 25 (FIG. 5b), whereupon the locking element 21 is locked to the first projection 24a in a pre-locking position (FIG. 5c). , This pre-locking position has the advantage that the first rail 12 is caught by the locking element 21 of the second rail 13 and gives the user the secure feeling that the sliding path is practically completed and a locking between the drawer 3 and the drawer pull-out guide 4 is brought about. A release of the Vorverriegelungsposition by manually pulling on the first rail 12 against the sliding direction 20 is no longer possible from this point. For the production of final connection, a user now has two different options available. According to a first variant, the first rail 12 can be moved further in the sliding direction 20, starting from the pre-locking position shown in FIG. 5c, wherein the locking element 21 is pressed down again by the second projection 24b of the first rail 12 against the force of the energy accumulator 25 (FIG. Fig. 5d). Following this, the second projection 24b is automatically locked to the locking element 21 under the action of the force of the force accumulator 25, so that the rails 12, 13 are in their connected state and are fixed to one another by the locking element 21 in the longitudinal direction (L) (FIG. 5e). According to a second variant, the first rail 12 (and thus also the second rail 13 coupled therewith) can be moved against the sliding direction 20, starting from the pre-locking position shown in FIG. 5c, by opening the drawer 3, then the drawer 3 is returned to its swinging momentum retracted the furniture body 2, wherein also the locking process described above (Fig. 5d, Fig. 5e) is brought about. Starting from the locked position (FIG. 5e), the locking of the rails 12, 13 by manual pulling on the first rail 12 against the sliding direction 20 is not releasable. This represents a safety aspect, because an unintentional release of the rails 12, 13 should be avoided from each other.

Fig. 6a shows the connected state of the rails 12, 13, wherein the locking element 21 of the second rail 13 is locked to the second projection 24b of the first rail 12. Fig. 6b shows the circled in Fig. 6a region "A" in an enlarged view. It can be seen that the locking element 21 in the connected state of the rails 12, 13 is covered by the central web 12c of the first rail 12. In the embodiment shown, the locking element 21 is in the connected state of the rails 12, 13 on an underside of the central web 12 c of the first rail 12 at. The cover of the locking element 21 has the advantage that in the connected state of the rails 12, 13 an unintentional actuation of the locking element 21 is avoided. The energy storage 25 for acting on the locking element 21 in the direction of the locking position is formed in the figure shown as a separate from the locking element 21 leaf spring made of steel, wherein the leaf spring presses with a bent end portion against the locking element 21. Fig. 6c shows the circled in Fig. 6a area "B" in an enlarged view. The mounted at the front end of the second rail 13 functional head 23 has at least one spring buffer 28 through which the rails 12, 13 in the connected state in the longitudinal direction (L) are arranged without play to each other. Namely, in the connected state presses on the front panel 5 of the drawer 3 arranged or trained fitting 29 against the spring buffer 28 of the functional head 23. In this way, the remaining play between the rails 12, 13 in the longitudinal direction (L) compensated.

To increase the ease of use furniture 1 are often equipped with ejectors through which the drawer 3 can be ejected from its closed end position in or on the furniture body 1 in an open position. Especially with handle-less drawers 3, the ejection devices are often designed such that they can be triggered by moving the drawer 3 from the closed end position in the direction of the furniture body 2. For this purpose, a certain play the drawer 3 in its closed end position to allow. The spring buffer 28 now allows the drawer 3, starting from its closed end position against the force of the spring buffer 28 in the direction of the furniture body 2 is movable, whereby ejection devices can be triggered with a touch-latch function. The spring buffer 28 is used in particular in so-called inner drawers for use in which the front panel 5 of the drawer 3 can not strike in the closed position on the front edge of the furniture body 2, but is arranged between the side walls of the furniture body 2. By applying pressure to the front panel 5 of the tray designed as an internal drawer 3, the first rail 12 can be moved against the force of the spring buffer 28 relative to the second rail 13, whereby the spring buffer 28 is deformed or bent and the ejection device can be triggered. After the triggering device has been triggered, the first rail 12 can be moved back into the starting position, if necessary by supporting the ejection device. In the illustrated embodiment, the spring buffer 28 is formed by at least one pressable plastic part. Alternatively, it is possible for the spring buffer 28 to have a stop member applied to the drawer 3 by a spring.

Fig. 7a-7e show the unlocking of the rails 12, 13, starting from the connected state, in which the locking element 21 of the second rail 13 with the Protrusion 24b of the first rail 12 is locked. For unlocking the rails 12, 13, an unlocking device 33 is provided which has at least one arranged on the first rail 12 engaging member 30 which in the connected state of the rails 12, 13 in a arranged on the second rail 13 recess 31 with a play in the height direction (H) is recorded. The recess 31 has a control cam 32, wherein the engagement element 30, starting from the connected state of the rails 12, 13 by manual lifting of the first rail 12 relative to the second rail 13 along the control cam 32 is feasible. In order to unlock the locking element 21 from the projection 24b, therefore, the first rail 12 must first be raised by a person relative to the second rail 13 in the height direction (H) by the amount Dc1 (FIG. 7b). After lifting, the first rail 12 is moved by a person in the extension direction (A), whereby the engagement member 30 is moved with a component along a extending in the extension direction (A) of the drawer 3 portion 32a of the control cam 32 (Fig. 7c), wherein is preferably provided that the section 32a at least partially extends obliquely with respect to a horizontal. In this way, the engagement element 30 can be raised by the amount Dc2 relative to the second rail 13. As shown in Fig. 7d, the first rail 12 is then lowered by manual force in the height direction (H) downwards, wherein the engagement member 30 along a vertical portion 32b of the cam 32 is moved. Only then is the first rail 12 movable independently of the second rail 13 and can, as shown in Fig. 7e, further moved in the extension direction (A) and thereby the drawer 3 are separated from the drawer extension guide 4. The unlocking of the rails 12, 13 thus takes place by a predetermined

Movement pattern, namely in the illustrated embodiment by lifting the first rail 12 in the height direction H (Fig. 7b), pulling in the extension direction A (Fig. 7c), lowering in the height direction H (Fig. 7d) and subsequent extraction in the extension direction A (Fig ). This combination of movements represents a safety aspect, because an unintentional separation of the drawer 3 is to be avoided by the drawer extension guide 4 in any case. In particular, it should be ensured that the drawer 3 (especially if it is the bottom drawer 3 in a furniture body 2) can not be solved by a mere pulling movement upwards of the drawer extension guide 4. After the pulling movement namely the drawer 3 must first be lowered again (Fig. 7d), so that the drawer 3 can be separated from the drawer pull-4.

8 a shows a perspective view of the drawer rail 11 with the first rail 12 to be arranged on the drawer 3 and the second rail 13 arranged on the drawer pull-out guide 4, which are locked together in the connected state by the locking element 21. At least one projection 24a, 24b may have an inclined surface 35, by means of which the locking element 21 can be moved in the direction of the release position when the rails 12, 13 are pushed on. Visible is arranged on the first rail 12 engaging member 30 which cooperates with the unlocking of the rails 12, 13 with a disposed on the second rail 13 control cam 32, as shown and described in connection with FIGS. 7a-7e. The control cam 32 may be formed, for example, by an edge of a recess 31 of the second rail 13.

8a and 8b show two different perspective views of the functional head 23, which is to be arranged at a front end of the second rail 13. For applying force to the locking element 21, at least one energy store 25, for example in the form of a leaf spring, is provided. Visible is also the crushable spring buffer 28, through which the rails 12, 13 in the longitudinal direction (L) are arranged without play each other and through which the drawer 3, starting from its closed end position against the force of the spring buffer 28 in the direction of the furniture body 2 is movable, so Ejectors are triggered with a touch-latch function. The functional head 23 moreover has a recess 36, for example in the form of a groove, so that the engagement element 30 does not collide with the functional head 23 of the second rail 13 when pushed on and during the separation of the rails 12, 13.

9a shows the functional head 23 in a slightly modified embodiment. The locking element 21 has a first stop surface 37a and at least one second stop surface 37b, wherein the first stop surface 37a or alternatively the second stop surface 37b is engageable with the first rail 12, so that the second rail 13, starting from the fully closed position through the Cooperation of the first stop surface 37a with the first rail 12 or alternatively by the interaction of the second stop surface 37b with the first rail 12 is movable into an open position. The second stop surface 37b is thus provided to take the second rail 13 of the drawer pull-out guide 4 in the event of faulty locking with the first rail 12, starting from the fully closed position into an open position. A faulty locking could be brought about, for example, by a very slowly performed insertion movement of the drawer 3, whereby the first rail 12 would not be properly connected to the first stop surface 37 a. Fig. 9b shows the functional head 23 shown in Fig. 9a in an assembled state at the front end portion of the second rail 13, wherein the two stop surfaces 37a, 37b of

Locking element 21 protrude from the second rail 13 upwards. The two stop surfaces 37a, 37b are spaced apart in the longitudinal direction (L) of the second rail 13 and extend substantially perpendicular to the longitudinal direction (L) of the second rail 13. When the first rail 12 is properly locked to the locking element 21 of the second rail 13 , so a part of the first rail 12 abuts against the first stop surface 37a of the locking element 21. If, on the other hand, the first rail 12 is incorrectly locked to the second rail 13, then the second rail 13 can be taken along by an interaction of the second inclined surface 37b with the first rail 12, starting from a complete closed position into an open position.

If the first rail 12 is pushed onto the second rail 13 of the drawer pull-out guide 4 during the assembly of the drawer 3 starting from FIG. 10a, the locking element 21 of the second rail 13 is counteracted by its cooperation with the first projection 24a against its resilient action bent down (Fig. 10b). If the first rail 12 of the drawer 3 is pushed further in the closing direction, the front panel 5 of the drawer 3 strikes against the front side 2 a of the furniture carcass 2 and thus can not be moved further in the closing direction (FIG. 10 c). However, it can also be seen in FIG. 10c that the locking element 21 of the second rail 13 is not properly locked to the second projection 24b of the first rail 12 because the second projection 24b comes to rest directly on the locking element 21. A faulty locking between the rails 12, 13 but can by a continued movement of the Drawer 3 can not be corrected in the closing direction, because the front panel 5 rests against the end face 2a of the furniture body 2 and thus a further movement of the drawer 3 is prevented in the closing direction. However, a faulty locking between the rails 12, 13 would also result in the drawer 3 remaining in an open position in an undesired manner.

To produce a correct locking between the rails 12, 13, first the drawer 3 (and thus the first rail 12) is pulled in the extension direction (A) (see FIG. 11 a), wherein the first rail 12, for example the second projection 24 b of FIG first rail 12, with the second stop surface 37b of the locking element 21 can be coupled. Due to the interaction of the rail 12 with the second stop surface 37b of the locking element 21, the second rail 12 can be pulled from a complete closed position into an open position.

In Fig. 11b, the drawer 3 has been moved again in the insertion direction (E), wherein the relative position between the second projection 24b and the second stop surface 37b remains unchanged due to the friction occurring between the rails 12, 13. By a continued movement of the drawer 3 in the insertion direction (E), the first rail 12 (and thus the second projection 24b) is further moved in the insertion direction (E), whereby the locking element 21 snaps back and the first stop surface 37a on the first rail 12, preferably at the second projection 24b of the first rail 12, rests without play. The correct locking between the rails 12, 13 is shown in Fig. 11 c, wherein the rails 12, 13 are fixedly arranged in the locked state relative to each other.
