Description

The invention relates to an arrangement with a drawer and a pull-out for the drawer, wherein the drawer has a drawer container and connectable to the drawer container front panel and wherein the pull-out at least one carcass rail for attachment to a furniture body and at least one relative to the carcass rail between an open position and a closed position movable drawer rail to which the drawer with the pull-out guide is fastened, with a releasable locking element through which in a locking position, the movement of the drawer rail in the closing direction relative to the cabinet rail before reaching the closed position in an intermediate position and in a release position the Movement of the drawer rail in the closing direction relative to the carcass rail is released until it reaches the closed position, and a piece of furniture with a furniture body and such an arrangement.

In pull-out guides, the drawer rail and the cabinet rail in the unassembled state are movable from a complete open position to a complete closed position relative to one another. The same applies if such a pull-out guide is mounted on both sides via the carcass rail in a furniture carcass. The fitting or fastening of a drawer on the pull-out guide is possible in the installed state of the pull-out guide, even if the drawer rail is in the closed position - ie completely inside - to the carcass rail. When inserting the drawer in the pull-out guide, the poor accessibility of the very rear or inside adjacent drawer rail can lead to problems. The problems are even greater when the drawer is already in use and a front panel of a front drawer is to be attached to the drawer, as this strikes the furniture body before it ever comes in sufficient proximity to the drawer.

Such an arrangement is already out of the AT 384 535 B known, in which a locking element in the form of a pawl inhibits the rail movements to each other. In this patent, however, the locking element only serves to facilitate the attachment of the drawer to the pull-out guide, since the drawer rail can not run unhindered between the open and closed positions back and forth.

Furthermore, the shows DE 33 26 400 A1 a drawer mounted on telescopic rails, wherein the movement between the telescopic rails is inhibited by a bolt. Also in this document, this bar can be solved only by hand. There is no functional connection of releasing the bolt with attaching a drawer. The bolt is mainly used to lock the slots mounted on the telescopic rails in a certain position, especially when fully extended telescopic rails.

Also the US 4,274,689 shows a locking element for inhibiting movement between rails of a pull-out guide. This locking element is mainly used to ensure that in complete open position, the drawer can not be easily removed because the stop member abuts in a recess of the carcass rail. Only by manually pressing the part, the locking position can be solved and then the drawer and the drawer rail are lifted from the carcass rail.

The object of the invention is therefore to facilitate the attachment of the drawer to the pull-out guide or the attachment of the front panel to the drawer container. In particular, the drawer rail should be easily accessible in the assembled state of the pull-out, so that the attachment of the drawer and the attachment of the front panel on the drawer container is easily possible.

This object is achieved in conjunction with the features of the preamble of claim 1 by a release element, by which the locking element is automatically unlocked, wherein the locking element is automatically unlocked when attaching the drawer to the drawer rail or when attaching the front panel already attached to the drawer rail drawer container , solved. As a result, only when attaching the drawer to the drawer rail or when attaching the front panel to the container, an automatic unlocking of movement inhibition between drawer rail and cabinet rail.

In principle, in order to explain the mutually alternative features of the characterizing part of claim 1, two variants are possible when assembling drawers and when attaching a drawer to a pull-out guide:

A first variant thus provides that a complete, four-sided drawer (rear wall, two side walls and front panel) is already assembled ready and ready and this assembled drawer is then mounted on the drawer rail. With this attachment, the movement inhibition between the drawer rail and the carcass rail is then released accordingly, so that the drawer rail can move into the complete closed position.

According to a second variant, however, it can also be provided that the drawer is not connected in one piece with the pull-out guide. Rather, an initially three-sided drawer (rear wall and two side walls) can be attached to the "forward-looking" drawer rail, with no unlocking of the movement inhibition between drawer rail and cabinet rail. Only with the attachment of the front panel on the rest of the drawer already fastened to the drawer rail, the unlocking of the locking element by the release element and the drawer can be moved to the closed position.

Before unlocking the drawer rail can not unhindered back and forth between the open position and the closed position on the carcass rail, but is prevented from complete freedom of movement and stopped at a certain point. This means that the drawer rail when inserting the drawer or when attaching the front panel can not move completely to the very back to the stop, but rather in an intermediate position is stopped further forward, in which given the accessibility and thus the attachment of the drawer or ., the front panel is easily feasible.

When the pull-out guides are mounted on a furniture carcass, it is often not clear which types of drawer are mounted. Above all, if it is not yet known what type of front panel has the drawer, which is possible during use, maximum closed position of the drawer rail to the carcass rail is not yet known. Namely, if the front panel is designed as a front drawer, the drawer rail can not reach the absolute closed position in the operating state, since previously strikes the front panel of the front drawer on the furniture body. But if the front panel is provided for an internal extension, the drawer rail relative to the cabinet rail completely in the closed position reach. If the drawer rail is completely in the closed position with the carcass rail when mounting the front panel on the drawer container, the front panel can not be mounted on the drawer or on the drawer rail, since it is already too far in the furniture carcass. Therefore, it is provided according to a preferred embodiment of the invention that the closed position of the drawer rail corresponds to a fully closed drawer, and that position of the drawer rail, in which it is lockable via the locking element relative to the carcass, just before, preferably 1 mm to 20 mm before which lies closed position.

According to a further preferred embodiment, a release element can be arranged on the drawer.

As already mentioned, the drawer can have a drawer container and a front panel which can be connected to the drawer container via a connecting element, wherein according to a very particularly preferred embodiment the release element can be arranged on the front panel or the connecting element. As a result, the lock is released only when attaching the front panel on the drawer container already attached to the drawer rail and only then can the drawer rail of the previously locked intermediate position reach the closed position. Thus, the mounting of the front panel regardless of the front panel type on the already mounted pull-out in furniture body is always possible. Only by attaching the lock is released.

Preferably, it can further be provided that the locking element - between a locked and a released position movable - on the pull-out, preferably on the drawer rail, is arranged and has a stop extension over which the locking element in the locked position on a boundary extension of the pull-out, preferably on the carcass rail, stops and stops the closing movement of the drawer rail to the carcass rail. It should not be ruled out that this delimitation extension can also be formed on the furniture body itself or that the locking element acts, for example, between the drawer container and the carcass rail. It could be provided, for example, that the drawer container mounted on the drawer rail without front panel never ever in the complete closed position can reach the locking element- Only after mounting the front panel, this lock could be repealed.

In general, two alternative embodiments of the present invention may provide that either the release member abuts the latch on attaching the drawer to the latch member and moves it from the locked position to the released position, or the release member in connecting the bezel over the connector to the drawer receptacle on the latch member abuts and this moves from the locked position to the released position. In any case, the second variant is preferred.

According to a further preferred embodiment, it may be provided that the locking element is verschenkbar mounted on the drawer rail and a stop on the drawer rail spring, preferably leg spring having, wherein when unlocking the release element, the locking element together with its Anschlagfortzsatz against the spring force of the spring in the dissolved Position pivoted.

If the locking element together with stop extension and spring is formed as a one-piece injection-molded plastic part, the production is particularly simple and also the mounting on the pull-out can be relatively uncomplicated.

Protection is also desired for a piece of furniture with a furniture body and an arrangement according to one of claims 1 to 9.

Representation of an alternative embodiment of the locking element.

Fig. 1 shows a furniture 20, wherein a pull-out guide 2 is mounted on the furniture body 4 in the upper area. From this pull-out guide 2, the carcass rail 3 is mounted on the furniture body 4. On this cabinet rail 3, the drawer rail 5 is slidably mounted, wherein the pull-2 is shown here in the closed position SS. It can already be seen that the attachment of a front panel 10 to a drawer 8 attached to the drawer rail 5 is no longer possible because they are too far into the furniture carcass and the distance between the front panel 10 and thrust container 8 is too large. This is especially true Fig. 1 a, in which an internal pullout I is shown. The thrust container 8 and thus also the drawer rail 5 is already in the complete closed position SS in the furniture carcass 4. The attachment of a front panel 10 for a front extension F would not be possible in this position SS, since this front panel 10 (as in Fig. 1b ) abuts the furniture carcass 4 already before reaching the closed position SS.

In Fig. 2 it can be seen how the parts of the pull-2 in the open position to each other OS. At the drawer rail 5, the locking element 6 is arranged. On the carcass rail 3 is the boundary extension 11. The locking element 6 is shown in the locking position V.

In Fig. 3 the drawer rail 5 is shown to the carcass rail 3 in the intermediate position ZS, wherein the locking element 6 abuts the boundary extension 11 and allows no further movement in the closing direction SR. In this position ZS, a drawer 1, consisting of drawer insert 8, front panel 10 and located therebetween connecting element 9 regardless of the front panel type F or I are easily attached to the drawer rail 5.

If then according to Fig. 4 the attachment of the drawer 1 to the drawer rail 5 is made and the release element 7 of the connecting element 9 has brought the locking element 6 in the release position L, the complete movement in the closing direction SR can be continued until reaching the closed position SS ( Fig. 5 ). The locking of the drawer 1 on the extension guide 2 can be done via known Verrastungs- or fastening devices.

In Fig. 6 the drawer container 8 is shown in fragmentary form, which consists essentially of a drawer 12 and an example of wood drawer bottom 13. In the front region of the side wall of the drawer 12, a receiving opening 14 is provided, in which the front panel 10 can be fastened via the connecting element 9. The connecting element 9 is fastened in the front panel 10 via fixing extensions 15 (for example dowels). Further is Fig. 6 a pull-out guide 2 is shown, on which the locking element 6 can be attached for example via a mounting insert 16.

Fig. 7 shows the assembled pull-out 2, consisting of a drawer rail 5, a cabinet rail 3 and attached to the drawer rail 5 mounting insert 16. Depending on the design of the pull-2, a third rail (middle rail 17) may be provided.

In the Fig. 8 . 9 . 10 and 12 the position of the drawer rail 5 to the carcass rail 3 is shown schematically at the top, the closing direction SR pointing to the left, whereas in the respective view of the locking area shown below the closing direction SR extends to the right.

Fig. 8 shows schematically above the position of the drawer rail 5 to the carcass rail 3 in the intermediate position ZS, wherein, as shown below in the view, the locking element 6 is in the locked position V. In this case, the stop extension 61 of the locking element 6 strikes the boundary extension 11 of the carcass rail 3.

In Fig. 9 then the drawer container 8 is attached to the located in the intermediate position ZS drawer rail 5.

In Fig. 10 the front panel 10 is mounted on the drawer container 8, wherein the installation is made possible by the distance A between the front side of the drawer container 8 and the furniture body 4 in the intermediate position ZS. If the drawer rail 5 were already completely in the closed position SS, the front panel 10 would already hit the furniture carcass 4 before reaching the drawer container 8. As can be seen in the view shown below, by connecting the front panel 10 and its connecting element 9 with the drawer container 8, the release elements 7 is moved against the locking element 6, whereby this locking element about the pivot point D against the spring force of the spring 62 - the drawer rail 5 is applied - rotated, whereby the stop extension 61 can no longer strike the boundary extension 11 and thus in this intermediate position ZS the locking element 6 reaches the release position L, whereby the entire drawer rail 5 (see Fig. 12 ) can be moved in the direction of the closed position SS.

In Fig. 11 Although the closed position SS between drawer rail 5 and cabinet rail 3 is not yet reached, yet an end position for the drawer 1 due to the striking of the front panel 10 is given to the furniture body 4. In this case, the front side of the thrust container 8 and the front of the furniture body 4 is substantially in the same vertical plane (distance A is minimal).

In Fig. 12 In contrast, it can be seen when no front panel 9 of a front pull F but a Innenauszugfrontblende 18 is mounted on the drawer container 8 of the drawer 1. In this case, a release element 7 may be provided on the front panel 18 of the inner drawer I in the same manner.

The Fig. 13 to 15 show again in 3D representations and views of the area of the pull-out guide 2, in which the locking element 6 abuts on the boundary extension 11 ( Fig. 13 ) or the unlocking by the release element 7 takes place ( Fig. 14 ) and after the unlocking the closed position SS is achieved ( Fig. 15 ).

Fig. 16 shows a drawer 1 from a drawer container 8 and a front panel 10 in a side view. The drawer container 8 has a drawer 12, via which the drawer 1 is attached to a drawer rail 5 a pull-2. At the drawer 12, a locking element 6 via a bolt-shaped pivot point D attached and in the locking position V with one end, which is formed by the stop extension 61, on the carcass rail 3 and its boundary extension 11 at. As a result, the drawer rail 5 together with the drawer 1 attached thereto is removed by the distance A from the closed position SS and further movement of the drawer 1 in the closing direction SR is inhibited. It is thus by the locking element 6, the locking position V can be fixed.

In contrast, the shows Fig. 17 the release position L, which is achieved in that the front panel 10 together with the connecting element 9 attached thereto (forms the front panel side part of a front fitting 21) to the drawer 12 (in particular at the container-side part 24 of the front fitting 21) is attached. In this case, the release element 7 formed by an extension of the connecting element 9 abuts on one end of the locking element 6, so that this locking element 6 rotates against the spring force of a spring 23 about the pivot point D and thus the other end (stop extension 61) of the locking element 61 from the boundary extension 11 of the carcass rail 3 is released. As a result, the distance A is minimized and the drawer rail 3 or the drawer 1 can reach the closed position SS.

The Fig. 18 and 19 with the details E and F show in perspective only the front fitting 21 in the locked position V or in release position L.
