Description

drawer system

The present invention relates to a drawer system with a cabinet body to be fixed to a cabinet body rail, at least one movable drawer rail and a bottom plate having a drawer container, wherein on the bottom plate a container rail is pre-assembled, which is connected to the movable drawer rail or connectable, wherein the upper edge of the bottom plate of the drawer container is above the upper edge of the drawer rail. Such a container rail is often used in a recess formed in the underside of the bottom plate and serves to connect the drawer container to a movable rail of a drawer extension guide. The drawer pull-out can optionally be designed as a two-part rail system with a cabinet body to be fixed to a cabinet body and only a relatively movable pull-out, or as a three-part rail system, between the carcass rail and the pull-out rail an additional center rail is slidably mounted, so as a full extension to allow the drawer container relative to a furniture body. In conventional solutions, the bottom plate is bordered with its lateral edge, for example, by a U-profile of the side frame, which results from this type of enclosure located at the top of the bottom plate abutting edge (eg DE 10 2008 024 673 A1), which is often disturbing is felt. Also reduces in such a border of the bottom plate, the clear width of the drawer container. In addition, there is the danger in conventional solutions that the bottom plate with its lateral edge - in particular at considerable loading of the drawer container - breaks.

Drawer systems according to the preamble of claim 1 are described, for example, in AT 400 999 B, in DE 91 15 465 U1 and in AT 403 648 B of the Applicant. In these prior art documents, the upper edge of the bottom plate is slightly above the upper edge of the rail to which the bottom plate is connected. The bottom plate rests against the interior of the drawer container facing side of the rail. Object of the present invention is to provide a drawer container of the type mentioned above while avoiding the above disadvantages, in particular, the useful volume of the drawer can be increased. This is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent subclaims.

According to the invention, it is thus provided that the bottom plate is guided completely over the rails of the drawer extension guide.

In this way, it is possible that the bottom plate up to the outermost edge - especially over the rails of a drawer pull-away - can be led out, thereby increasing the useful width of the drawer. The bottom plate can therefore come close to a side wall of the furniture body, with very narrow and in cross-section substantially rectangular drawer side walls can be arranged.

Here, it is also possible to bring about a rectangular arrangement between the bottom plate and the drawer side wall, whereby no space in the drawer is lost by a convexly curved wiper edge of an inner profile side wall of the drawer. By a right-angled arrangement of the side wall to the bottom plate also results in an improved storage possibility, for example of cuboid boxes.

According to one exemplary embodiment, provision may be made for the container rail to have a section lying on the underside of the bottom plate and having a substantially Z-shaped or substantially S-shaped cross-section. Such a design of the container rail, the surface of the bottom plate can be lowered and brought closer to the top of the drawer rail. The edge region of the bottom plate can be made with a lower thickness, without sacrificing the stability of the bottom plate, since this weakening is compensated by the intended container rail. In a possible development of the invention it can be provided that adjoins the Z-shaped or S-shaped portion of the container rail, a substantially vertical profile section, which bears against the lateral edge of the bottom plate. Furthermore, a right-angled support leg can continue on the vertical profile section, which rests on the top of the drawer bottom. The described embodiment of the container rail, the lateral edge of the bottom plate can be completely enclosed, whereby the risk of liquid penetrations is prevented in the bottom plate, especially if it is made of pressed chip material.

According to one embodiment of the invention, the drawer container may have at least one side wall, which is formed integrally with the container rail. In other words, the container rail and the side wall can be formed from a single piece of sheet metal or aluminum, which is manufactured and canted, for example, by the strand-pressing method.

Further details and advantages of the present invention will be explained with reference to the following description of the figures. 1 shows a perspective view of a piece of furniture with drawer containers, which are movably supported by drawer extension guides in relation to a furniture carcass,

Fig. 6 parts of the drawer container in an exploded view. 1 shows a perspective view of a piece of furniture 1, wherein drawer containers 3 are movably mounted via drawer pull-out guides 4 relative to a furniture body 2. The drawer pull-out guide 4 is formed in the embodiment shown as a three-part rail system and has a furniture body 2 to be fastened to the carcass rail 5, a movable relative to the center rail 6 and an extendable drawer rail 7, which is connected to a mounted on the drawer container 3 and not visible here container rail , However, it is also possible to execute the drawer extension guide 4 as a two-part rail system with only one extendable rail, in which case the container rail preassembled on the drawer container 3 can also function as a drawer rail for realizing a full extension. The drawer container 3 each have a bottom plate 3a, to which the container rail is pre-assembled.

FIG. 2a shows the drawer container 3 mounted on the drawer pull-out guide 4 in cross-section. The carcass rail 4 is fixed to the side wall of the furniture body 2, recognizable is the displaceable center rail 6 and the extendable drawer rail 7. On the bottom plate 3a a container rail 8 is fixed, which is connected to the drawer rail 7 of the drawer extension guide 4 or detachably coupled with this. In the embodiment shown, there is no relative movement between the container rail 8 and the drawer rail 7 when the drawer container 3 is inserted and withdrawn. The container rail 8 extends in sections on the underside of the bottom plate 3a and is used in the figure shown in an opening towards the edge of the bottom plate 3a out. By this step-shaped recess on the underside of the bottom plate 3a, this can be placed deeper, so that the top of the bottom plate 3a above the top edge of the drawer rail 7 or about at the same level. The container rail 8 can be fixed via attachment means 9 to the underside of the base plate 3a, for example by means of screws or with fastening claws, which are pressed into the underside of the base plate 3a. With the Behältnisschiene 8, a side wall 10 may be connected, which is formed in the embodiment shown as a frame profile with a profile inner side wall and a profile outer side wall. Good visibility is the very slim design of the side wall 10 and the ability to bring the bottom plate 3a very close to the furniture body 2. The illustration below shows the bottom plate 3a with its Behältnisschiene 8, which forms a substantially Z-shaped in cross-section. Alternatively, an S-shaped cross section of the container rail 8 may be provided, in particular when the recess of the bottom plate 3a has a groove. The container rail 8 has a lower horizontal leg 8a for abutment or attachment to the underside of the bottom plate 3a and an upper horizontal leg 8b for abutment or attachment to or in the recess of the bottom plate 3a, the lower horizontal leg 8a and the upper horizontal leg 8b are connected to each other via a, preferably substantially vertical or curved, web 8c. At the upper horizontal leg 8b is followed by a vertical profile section 8d, which bears against the lateral edge of the bottom plate 3a. The profile section 8d is adjoined by a support leg 8e, which projects substantially at right angles and rests on the upper side of the base plate 3a. However, this support leg 8e does not appear as a disturbing abutting edge in the interior of the drawer container 3 in appearance, since this transition point can be covered by the side wall 10.

2b shows a possible variant of the container rail 8. In contrast to FIG. 2a, the web 8c of the container rail 8 has a projection 11 extending horizontally in cross-section, which projection is inserted in a corresponding longitudinal groove 12 of the bottom plate 3a. In this way, an improved local force distribution is brought about, whereby the risk of breakage of the bottom plate 3a is reduced. Overall, an improved stiffening and increased stability of the container rail 8 is achieved. The projection 11 may extend substantially over the entire length L (FIG. 6) of the container rail 8.

FIG. 3 a shows the possibility of producing the container rail 8 and the side wall 10 of the drawer container 3 from a single piece of metal. The drawer pull-out guide 4 is again designed as a three-part rail system with carcass rail 5, middle rail 6 and drawer rail 7. The container rail 8 rests with its lower horizontal leg 8a on the underside of the bottom plate 3a, is guided into the recess of the bottom plate 3a and includes the lateral edge of the bottom plate 3a. Subsequently, the container rail 8 forms the side wall 10 with a profile inner side wall 10 a and a Profile outer side wall 10b of which extend substantially parallel to each other. The lower end of the profile outer side wall 10b forms a U-shaped channel 14, whereupon the profile is closed again at the connecting region 13. This compound can be done for example by Toxen or clinching.

3b shows a non-inventive embodiment with another known type of drawer pull-out guide 4. The container rail 8 is substantially Z-shaped and comprises the mutually parallel legs 8a and 8b, which are interconnected by a profiled web 8c. The side wall 10 is formed as a hollow chamber profile and is slipped over the rails 5, 6, 7 of the drawer extension guide 4 and is connected to the container rail 8.

Fig. 4 shows parts of the drawer extension guide 4 slidably mounted drawer container 3 in an exploded view. The drawer pull-out guide 4 comprises, by way of example, a three-part rail system with the cabinet rail 5 to be fastened to the furniture body 2 (FIG. 1), the middle rail 6 and the drawer rail 7 to be connected to the container rail 8. The bottom plate 3a of the drawer container 3 has a recess, preferably a step-shaped recess 15, which extends substantially over the entire length thereof and which is open to the edge of the bottom plate 3a. The recess 15 extends parallel to the lateral edge of the bottom plate 3a. Visible is also the longitudinal groove 12 of the bottom plate 3a, which also extends over the entire length thereof. The container rail 8 has mutually parallel legs 8a and 8b, which are interconnected by a substantially vertical web 8c. The container rail 8 is provided in the front end region and in the rear end region in each case with upwardly projecting attachments 16, 17, which are provided for fastening a drawer rear wall 19 and a front panel 3b. The container rail 8 forms with the two upwardly projecting attachments 16, 17 in a side view of a U-shape. At the back of the front panel 3b, a holding part 18 is to be mounted, which can be coupled to the front attachment 16. The attachment 16 has at least one adjusting device 16a, by which the position of the holding part 18 (and thus the position of the front panel 3b) is adjustable. In the embodiment shown, a plate-shaped wall element 20 is inserted between the front and the rear attachment 16, 17 and cap-like covers 21 a, 21b held. The wall element 20 thus lies only loosely between the articles 16, 17 and takes on pulling and when inserting the drawer container 3 relative to the furniture body 2 no forces. The wall element 20 can therefore be designed as a decorative insert of glass, stone, wood, plastic or metal. The proposed container rail 8, it is also possible to run down a glass wall element 20 to the upper edge of the bottom plate 3a, resulting in a particularly attractive appearance of the drawer container 3. Of course, it is also possible to put over the essays 16, 17, a side wall cap made of metal.

5a shows the drawer container 3 mounted on the drawer pull-out guide 4 in cross-section. The container rail 8 pre-assembled on the drawer container 3 has, in cross-section, a substantially Z-shaped or S-shaped section with the leg 8a resting against the underside of the bottom plate 3a, the web 8c and the upper horizontal leg 8b extending in the recess 15 of FIG Base plate 3a are located. The upper edge 22a of the bottom plate 3a lies above the upper edge 22b of the drawer rail 7 or approximately at the same level. The side wall 10 with the profile inner side wall 10a and the profile outer side wall 10b is formed in the embodiment shown as a separate from the container rail 8 profile, which is connectable by suitable means with the container rail 8.

Fig. 5b shows the drawer container 3 of FIG. 3, wherein the drawer extension guide 4 is hidden. It can be seen that the proposed construction makes possible a very narrow embodiment of the side wall 10, wherein the ratio of the width (a) of the side wall 10 to the width (B) of the container rail 8 measured transversely to the drawer withdrawal direction can satisfy the following condition: a: B s 1: 3, preferably a: B 1: 6.

Fig. 6 shows parts of the drawer container 3 in an exploded view. The container rail 8 has an attachment 16 for supporting a side wall 10 and / or a plate-shaped wall element 20 in the front end region, wherein the attachment 16 is also provided for supporting or adjusting a retaining part 18 to be mounted on the rear side of the front cover 3b. The ratio of the width (b) of the attachments 16, 17 measured transversely to the drawer pull-out direction X to the width B (see Fig. 5b) of the container rail 8 can satisfy the following condition: b: B 1: 3, preferably b: B s 1: 5. Between the articles 16, 17, a decorative wall element 20 can be inserted, wherein the wall element 20 is secured via attachable covers 21 a and 21 b against falling out. Alternatively, it is possible to put over the essays 16, 17, a metallic side wall 10, wherein the essays 16, 17 find place in mounting position between the profile inner side wall 10a and the profile outer side wall 10b. In a side view, the ratio of measured in the drawer longitudinal direction length (I) of the articles 16, 17 to the length (L) of the container rail 8 can satisfy the following condition: l: L ^ 1: 10, preferably l: L .5 1:15.

A particular advantage of the construction described lies in the fact that the wall element 20 can extend almost completely over the entire length L of the container rail 8, in particular due to the described proportions of the attachments 16, 17, the lower longitudinal edge of the wall element 20 being in the mounting position approximately the same height as the upper edge 22a (Fig. 5a) of the bottom plate 3a may lie. In this way, the drawer container 3 can be given a special aesthetics.
