Description

The present invention relates to a cabinet furniture with a pull-out, preferably a drawer, the pull-out with rails of drawer guides connected and fixed in all coordinate directions relative to the rails and tool-free as needed separated from the rails, the pull-out in the back area against lifting of and secured against transverse displacement relative to the rails.

Cabinet furniture of the generic type are known per se and generally offer the advantage that an extractable part in a simple manner against the rails of drawer guides can be fixed and, if necessary, also just as easily and without the aid of tools from the rails is separable.

The prior art is on the DE 92 15 250 U1 directed.

The present invention has for its object to provide a cabinet furniture of the generic type, in which the releasable connection between the extract part and the rails is realized with structurally extremely simple means and a possible separation of the extractable part of the rails of technically inexperienced people easily possible is.

This object is achieved in that is provided for coupling the extract part with the front end portions of the rails each have a part attached to the extension or on the rails molded part, each mold part having two mutually parallel, spaced from each other and the respective rail in the area to the running rail front side open longitudinal slot or on the extractable part to be coupled and extending to the extracting part back longitudinal slot passing through spring webs, which have at their longitudinal slot passing ends in opposite directions splayed tabs and at their the opening of the respective longitudinal slot facing ends with also in opposite directions to each other splayed holding legs are equipped, which form and / or non-positively within the respective longitudinal slot against displacement in the direction of the front of the rails out support it.

For the detachable fixing of a pullout of the rails of pullout guides are according to the present invention, in addition to the already known means in the rear end of the rails only still requires two mold parts, which are fixed in the front end portions of the extract part at this and fix the extraction part in all three coordinate directions after the coupling with the rails.

The alternative solution provides to fix the moldings in the front areas of the rails and to fix them after coupling with the pull-out in an open towards the back of the pullout longitudinal slot of the pullout in all three coordinate directions.

If the pull-out part is to be removed from the rails as required, this can be done by raising the pull-out part upwards in its front end area with respect to the rails, whereby the separation of the moldings from the rails is brought about. This is possible because the tongues spread apart at the ends of the spring webs passing through the longitudinal slots are compressed in the exertion of upward forces by the lifting of the extension part due to the resilient properties of the spring webs and can be pulled through the respective longitudinal slot.

An unintentional release in this direction, however, is completely excluded, since in normal operation, ie, when pulling out or pushing a pullout, corresponding forces do not occur or only in an order of magnitude, which is not suitable, the splayed tabs at the lower ends of the spring bars so far enough that they can be passed through the respective longitudinal slot upwards.

Once deliberate manipulation, the extract part in the front end - as described above - is separated from the rails, the extractable part in the longitudinal direction of the rails can be completely deducted from this, as in the rear end a fixation of the extract part relative to the rails only transverse to the longitudinal axes of the Running rails and thus a disability-free removal in the longitudinal direction of the rails is possible.

If the pull-out part is to be coupled again to the rails, the pull-out part is placed in a horizontal position on the rails, in which the two mold parts are located in front of the open ends of the longitudinal slots. Now, by moving the extract part in the insertion direction, the respective molded part with its spring bars in the space provided for longitudinal slots be inserted, wherein the at the longitudinal slots passing through the ends of the spring bars provided, in opposite directions spread apart tabs engage behind the rails in the region of the longitudinal slots and thus prevent inadvertent lifting of the extract part of the rails. The holding legs provided at the ends of the spring webs facing the respective opening of the longitudinal slots are pressed together when inserted into the longitudinal slots and can then be supported positively and / or non-positively in the longitudinal slots within the longitudinal slot. As a result, the pull-out part is securely fixed against a relative displacement with respect to the rails, so that the pull-out part is fixed in all imaginable coordinate directions with respect to the rails.

Further features of the invention are the subject of dependent claims.

Embodiments of the invention are illustrated in the accompanying drawings and will be described in more detail below.

In the FIGS. 1 to 7 is denoted by the reference numeral 1 a total of an extract part of a cupboard furniture not shown, which is formed in the concrete embodiment as a drawer.

The pull-out part 1 is held longitudinally displaceable in a known manner via pullout guides 2 in the body of a cabinet cabinet and out.

The pullout guides 2 are arranged in each case in the region of the two longitudinal sides of the pullout part 1 and comprise at least one guide rail 3 fixable on the body side and a running rail 4 which can be connected to the pullout part 1, if necessary, the pullout guides 2 also have a center rail which is to be considered of lesser importance on.

The connection of the pull-out part 1 with the rails 4 of the pullout guides 2 takes place in the rear region of the rails 4 and the pullout part 1 via so-called fishing hooks 5, which are provided in the rear end of the rails 4 and not shown in the drawings openings in the rear end of the Pull-out parts 1, in which the catch hooks 5 of each running rail 4 engage with the pull-out part 1 mounted in these openings. This connection technology in the rear end region is known per se and therefore not shown in further detail. It should be noted that is secured by the fishing hooks 5 in the rear end of the rails 4 and their intervention in the rear openings of the extract part 1 this in the rear end relative to the rails 4 against both vertical and horizontal displacement transverse to the longitudinal axis of the rails 4. A determination of the pullout part 1 in the longitudinal direction of the rails 4 is not possible by the fishing hooks 5.

Instead of the described connection of the pull-out part 1 in the rear end region of the rails 4, of course, other variants of known type can be used.

In the front end region, the connection of the extension part 1 with the rails 4 via molded parts 6, which are attached to the pull-out part 1 directly or indirectly to adapters 7, wherein the adapter 7 are fixedly connected to the pull-out part 1 in a known manner.

The molded parts 6, which are preferably produced in one piece from a metal, preferably from spring steel, have a pocket 8 in the connection region to the adapter 7, into which a tongue 9 exposed out of the adapter 7 engages. This is shown in particular by the FIGS. 15 and 16 ,

In this case, each of the tongue 9 overlapping the upper side material layer of the molded part 6 is provided with a projecting towards the pocket 8 locking tongue 10 which engages in a recess 11 of the respective tongue 9. In this case, the recess 11 may be dimensioned so that a displacement of the molded part 7 after the latching of the latching tongue 10 in the recess 11 is no longer possible, but it is also conceivable to dimension the recess 11 such that a small possibility of displacement of the molded part 6 transverse to the longitudinal axis of the track 4 is still possible, as in FIG. 16 is shown. Preferred in the overall concept of the present invention is an embodiment in which one molding 6 is immovable and the other molding 6 is displaceable within limits to allow tolerance compensation between the two spaced apart rails 4.

Each molded part 6 is provided with two mutually parallel and spaced from each other having spring bars 12 which have at their lower ends in opposite directions splayed tabs 13.

At their the front of the rails 4 facing ends of the spring bars 12 are also equipped in opposite directions to each other splayed support legs 14.

At their seen in the direction of insertion front ends of the spring bars 12 are provided with guide plates 15 which are angled zuweisend of the spring bars 12 starting.

This structural design of the moldings 6 results in particular very clearly from the FIGS. 14a to 14 f.

The rails 4 are each equipped with a longitudinal slot 16 open towards its front end. In this case, the respective longitudinal slot 16 is provided with an insertion opening 17, the width of which is smaller than the distance between the free ends of the support legs 14 which are spread apart relative to one another seen the running rail 4, the respective insertion opening 17 is limited by insertion bevels 18.

By facing each other guide tabs 15 and the insertion bevels 18, the molded part 6 can be safely inserted into the longitudinal slot 16 of the respective track rail 4. Since each mold part 6 is fixedly connected to the pull-out part 1 in the direction of insertion, each mold part 6 is displaced into a respective longitudinal slot 16 when the pull-out part 1 is inserted into a furniture carcass up to an end limit of the insertion path of the pull-out part 1. In this inserted state, the free ends of the retaining legs 14 are supported in a region 19 of the longitudinal slot 16 which is widened in relation to the insertion opening 17, this being the same as in the exemplary embodiment of the invention FIGS. 11a to 11c can be done on ratchet teeth 20 or by cutting the outer edges of the retaining leg 14 on straight flanks 21 of the extended portion 19 of the longitudinal slot 16, in other words, the anchoring or fixing or support of the retaining legs 14 against pushing back of the molded part 6 form and / or non-positively respectively.

In this way, the pull-out part 1 is secured against a longitudinal displacement relative to the running rail 4 after the first complete insertion into a furniture carcass.

The spring bars 12 of the mold parts 6 are in the inserted state in a portion 22 of the longitudinal slot 16 whose width corresponds to the distance between the two spring bars 12 and whose length is dimensioned so that the tabs 13 are already in the position in the section 22 run when the holding legs 14 have passed through the insertion opening 17, which is the Figures 13 . 15 and 16 clearly show. In the exemplary embodiment with latching teeth 20, the section 22 in the region of the latching teeth 20 is dimensioned by the tooth tips on the opposite flanks of the longitudinal slot 16. As a result, the pull-out part 1 is fixed against horizontal transverse displacement relative to the running rail 4.

The lifting of the extract part 1 of the running rail 4 is prevented by the at the lower ends of the spring bars 12 in opposite directions splayed tabs 13, which also clearly from the FIGS. 15 and 16 results. In order for a pull-out part 1 is fixed after installation in all coordinate directions against displacement relative to the running rail 4.

In the event of a disassembly required or desirable, it is sufficient to lift the pull-out part upwards in its front end area, as in FIG FIG. 2 indicated. In this lifting, the tabs 13 are compressed due to the resilience of the entire molded part and moved through the narrowed portion 22 of the longitudinal slot 16. Thus, the extraction part 1 is separated from the front end portions of the rails 4 and can now, as in FIG. 3 represented by further withdrawal from a furniture body completely separated from the rails 4, since the pull-out part 1 can be easily withdrawn from the rear fishing hooks 5 of the rails 4.

If the pull-out part 1 is to be mounted again, it is sufficient to put the pull-out part 1 in a horizontal position on the rails 4, in which the moldings 6 are still outside the longitudinal slots 16, as in FIGS. 4 and 5 clearly shown. By inserting the pull-out part 1, the catch hooks 5 reach the engagement area to the rear openings of the pull-out part 1 and the mold parts 6 are inserted through the insertion opening 17 under temporary compression of the rear holding leg 14 in the region of the longitudinal slot 16 and then opposite in the manner described above the rails 4 fixed.

It has already been described above that one of the molded parts 6 is laterally movable within certain limits relative to a running rail 4, so that tolerances at different distances of the rails 4 can be compensated for each other. The threading of the mold parts 6 in the longitudinal slots 16 is thereby simplified by the insertion bevels 18 on the one hand and the guide tabs 15 forming an insertion tip.

In the illustrated embodiments, the mold parts 6 are fixed to the mentioned tongues 9 of an adapter 7, wherein the adapter 7 in turn is fixedly connected to the pull-out part 1.

The adapters 7 are used in known manner for supporting side frames, but it should be noted that in the event that an extract part is constructed differently and has no adapter, the mold parts 6 can also be attached directly to the extract part.

The locking teeth 20, on which the ends of the retaining legs 14 are supported, can, as in the embodiment of the FIGS. 11a to 11c , 16 may be arranged symmetrically on both sides of the longitudinal slot 16, but it is also possible, the latching teeth 20 in the longitudinal direction of the longitudinal slot 16 offset from each other to arrange, so that a finer detent is achieved without an extremely fine pitch of the ratchet teeth 20 is required wherein in these arrangements in each case only one holding leg 14 engages on the corresponding latching tooth 20. The offset ratchet teeth 20 show the Figures 5 and 7 very clear, with in FIG. 7 the engagement of a retaining leg 14 on the locking tooth 20 is shown.

An alternative solution to the illustrated embodiments is that the mold parts 6 can also be attached to the rails 4, which is also advantageous in this case if one mold part 6 fixed fixed and the other mold part 6 transversely slidably mounted on the associated running rail is. In this case, parts of the pull-out part 1 or fixed to this adapter 7 are then provided with longitudinal slots 16 which are open to the pull-back part. It is practically a kinematic reversal of the design principle according to the described embodiments.
