Description

Expandable and push-in drawer bottom foil

The invention relates to a drawer comprising a drawer bottom with a plurality of, in particular regularly arranged, recesses and with at least one drawer insert with insertable into the recesses of the drawer bottom plug extensions.

Such a drawer or storage device for objects in furniture is known from DE 102 42 518 B4. This is a drawer with recesses in the drawer bottom shown (a so-called hole bottom) in which drawer inserts or subdivision elements such as partitions or the like in any arrangement and orientation can be inserted.

Furthermore, DE 20 15 313 A1 and FR 2545340 A1 show examples of drawers with perforated bottom and drawer inserts or dividing walls which can be anchored in the holes with plug-in extensions. From DE 18 94 424 U and DE 93 20 567 U1 drawers with perforated bottom and variable plug extensions of the drawer insert are known.

A major disadvantage of such a design is that when using such drawers, the recesses or holes can easily become dirty and small parts can hide in the recesses. In addition, the cleaning and cleaning of such drawer bottoms or perforated floors is only possible in a cumbersome and complex manner.

From DE 198 22 972 A1 Although a similar, but non-generic, execution known in which between the container (drawer insert) and the bottom of a flexible and preferably roll-up support, for example, plastic, can be arranged. But there are no recesses provided in the actual drawer bottom. The recesses or nubs are rather formed in the support itself, whereby containers with corresponding projections or recesses can be held on the support. Also in this embodiment, there is a significant problem in the complicated and complex cleaning of the drawer or the support. Furthermore, the DE 20 2004 001 788 U1 is known, which has a drawer with drawer inserts and arranged between drawer insert and drawer bottom film. From DE 37 11 063 A1 a drawer with arranged on the drawer bottom sheet is known to simplify the cleaning of the drawer. WO 2007/031097 A1 shows an elastic film arranged between drawer inserts and drawer bottom, to which the inserts are anchored by perforating the film. The drawer bottom has no perforation.

The object of the invention is therefore to specify a comparison with the prior art improved drawer. In particular, the cleaning and cleaning should be easy and uncomplicated while at the same time the attachment or insertion of drawer inserts in recesses of the drawer bottom should be possible.

This object is achieved in that between the drawer insert and drawer bottom at least partially a - preferably elastic - stretchable film is arranged. Thus, the drawer bottom is covered for the most part or in the desired areas of a film whose extensibility allows the insertion of the drawer inserts in individual recesses or holes, which only needs to be wiped off the substantially flat film surface for cleaning and no dirt in the plurality of recesses passes.

Preferred embodiments of the present invention can provide that the stretchable film substantially covers the entire drawer bottom and the recesses are formed in the form of holes passing through the drawer bottom. The drawer bottom may also be a continuous plate made of any stable material, wherein on this continuous drawer bottom, a so-called hole bottom may be additionally applied over which the stretchable film is stretched.

According to a preferred embodiment it can be provided that the stretchable film is partially connected to the drawer bottom, preferably glued to this, laminated or pressed. The stretchable film is included preferably only in the edge region of the drawer bottom (ie in the area of the drawer side, drawer front and rear wall) connected to the drawer bottom. The film need not necessarily be fixedly connected to the drawer bottom, but can be pinched by the arrangement or attachment of the front, back and side walls between these parts and the drawer bottom, whereby the film is stretched over the recesses in the drawer bottom. Depending on the distance between recesses or holes but can also be useful that in these intermediate areas a connection between drawer bottom and film can be provided. Another possibility is that the film and the drawer bottom are produced in a two-component injection molding process.

A particularly preferred embodiment may provide that the stretchable film in the ground state spans or covers the recesses in the drawer bottom and is sack-like depressible starting from this basic state by plug-in extensions of the drawer insert into individual recesses of the drawer bottom. This allows the drawer to be divided and equipped as desired. Now, if the drawer to be cleaned, the drawer inserts or subdivision elements can be easily pulled out, the stretchable film after removal of the insertion extensions of the drawer insert substantially returns to the flat initial shape. It is preferably provided that the stretchable film is elastic. As a result, the film returns completely after the removal of the drawer inserts and immediately returns to the most level possible initial shape.

However, in order to simplify the cleaning, a complete return to the flat initial shape in practice is not necessary, since even with a strange shape of the film, the cleaning activity is facilitated and compared to the prior art can be performed much easier. Therefore, it may alternatively be provided that the stretchable film is viscoelastic.

The viscoelasticity of a polymeric melt or a solid is characterized by its partially elastic and partially viscous behavior. The material relaxes or regenerates after removal of the external force (plug-in extension) only incompletely. The remaining energy or force is in the form of flow processes (Retardation) degraded, whereby the initial wave-shaped formation of the film after removing the drawer inserts over time in the form before the force, ie, returns to a substantially flat shape.

A further preferred embodiment variant can provide that the stretchable film can be pressed at least partially into the recess of the drawer bottom by a plug-in extension of the drawer insert so that the elastic film is at least partially clamped between the drawer insert and the drawer bottom. The film thus not only ensures easier and easier cleaning, but also achieves additional jamming of the drawer insert in the recess.

Especially if no removal of the drawer inserts after attaching these drawer inserts in the recesses of the drawer bottom is more desirable, it can also be provided that the stretchable film is pierceable by a plug-in extension of the drawer insert. Although the film is destroyed or torn in the areas of the plug extensions, but this does not bother, as no removal of the drawer inserts is provided. The cleaning of the drawer bottom or the film thereon between the individual drawer inserts is still much easier in contrast to a foil-less design. In this embodiment, the stretchable film is only partially disposed between the plug-in extension and the recess, since the film is penetrated by the plug-in extension. Due to the wider in contrast to the plug extensions execution of the drawer inserts, which bear in the direction of drawer bottom areas substantially continuously on the film, still can not get dirt through the torn areas of the film in an underlying recess or in the entire drawer bottom.

A preferred embodiment of the present invention can provide that the plug-in extension of the drawer insert inserted into the recess is movable or adjustable with respect to the recess such that the distance between the plug-in extension and the recess is at least locally variable, whereby the plug-in extension additionally in the recess can be clamped or spreadable. In this case, a further preferred embodiment provides that the Plug extension is movable by an actuating element on the drawer insert about a preferably vertical axis of rotation.

A possible concrete embodiment of this additional clamping or spreading can be embodied such that between one, in cross section to the rotation axis elliptical portion of the plug extension and the recess corresponding clamping elements are arranged, wherein the distance of the clamping elements to the recess by turning the plug extension is variable.

In order to facilitate the attachment of the drawer inserts or to find the underlying under the stretchable film recesses, it may preferably be provided that the stretchable film is transparent or that on the stretchable film according to the underlying recesses in the drawer bottom markings are applied.

A suitable film for the invention should at least partially meet the following requirements: light, hygienic clean, oil and grease resistant, abrasion resistant, non-slip surface, scratch resistant, cut resistant, tear resistant, tear resistant, elastic, dampening or springy, good resilience, heavy metal -, halogen- and plasticizer-free (REACH-compliant). The lifetime of a corresponding film should be at least about 20 years and it should be usable in the temperature range of room temperature ± 10 ° C. For transport and storage this area should be at least between -30 ° and + 60 ° C. According to a preferred embodiment of the present invention, the film consists of liquid silicone (liquid silicone rubber - LSR). Typically, this liquid silicone rubber consists of about 70% linear siloxanes, about 30% of fillers and about 1% of various additives. The thickness or material thickness of such a film or layer is about 0.1 to 0.5 mm, depending on the manufacturing method.

Protection is also desired for a piece of furniture with a drawer according to one of the above claims. Further details and advantages of the present invention will be explained in more detail below with reference to the description of the figures with reference to the exemplary embodiments illustrated in the drawings.

1 shows the drawer 1 with the side walls 11, the rear wall 12 and the drawer front 10. In between, the plurality of recesses 3 in the drawer bottom 2 can be seen through the stretchable and transparent film 5, wherein several drawer inserts 4 are inserted in individual recesses 3 ,

In Fig. 2, the section CC shows the two-part drawer bottom 2, which consists of the continuous drawer bottom 2b and the hole bottom 2a arranged thereon. As can be seen from the detailed view D, the extensible film 5, also via the recesses 3, is stretched over the perforated bottom 2a continuously. In Fig. 3 can be seen in particular in detail view A, as drawer inserts 4 are inserted via the plug extensions 6 in the recesses 3 of the bottom plate 2a, wherein between the hole bottom 2a and its recesses 3 and the drawer insert 4 and the plug extension 6. the stretchable film 5 is formed bag-like and surrounding the entire plug-in extension 6 in the region of the recess 3.

In Fig. 4 drawer inserts 4 are each shown with a plurality of plug-in extensions 6. Such a drawer insert 4 may be formed as a partition wall 4b or as a kind of tub 4a for storing small parts. Another possibility is to form the drawer insert 4 as a positioning element 4c, for example in the form of a positioning pin. These can be so mounted in individual (or more) recesses 3 that stored in the drawer 1 items such as plates, positioned between these positioning 4c and can be stored as safe as possible.

In Fig. 5, these different drawer inserts 4a and 4b are inserted into the drawer 1.

FIGS. 6 and 7 show the drawer insert 4 with the actuating element 7 in respectively different positions, wherein this actuating element 7 can move or rotate the central plug-in extension 6.

In Fig. 8, an additional partition 13 is mounted on the drawer insert 4 shown in FIG. 6 in addition to its holding extensions 14.

In Fig. 9, the components of Fig. 8 are shown in an exploded view, wherein it can be seen that the actuating element 7 via the rotary shaft 15, the elliptical portion 8 of the plug extension 6 is actuated, said elliptical area 8 corresponds to two clamping elements 9, the at corresponding rotation are pressed outwards, whereby the distance between the recess 3 and plug extension 6 is variable. The elliptical area or body 8 is in the form of a cylinder with an elliptical base. In Fig. 10 the drawer insert 4 is shown in the upper view before introduction into the drawer bottom 2, wherein the actuating element 7 is in non-clamping position while in the lower illustration, the actuating element is rotated by 90 ° and thereby takes place a deadlock (see in the Detail Fig. 12).

In FIGS. 11 and 12, cross sections are drawn through the retaining element 4 and the drawer bottom 2 in accordance with the illustrations shown in FIG. Specifically, in the detail views G and H of FIG. 12, it can be seen comparatively how the rotation of the rotary shaft 15 (about the rotation axis X) and of the elliptical area 8 (cylinder body) connected in one piece, the clamping elements 9 are moved away from each other (detailed view H). while in the detailed view G, the flattened side of the cylinder with elliptical base surface does not yet press apart the clamping elements 9, whereby the distance d between clamping element 9 and recess edge or drawer bottom 2 still exists. Furthermore, it can be seen in FIG. 12 that the main area of the drawer insert 4 is wider than its push-in extension 6, whereby the area of the drawer insert 4 facing the direction of the drawer bottom 2 bears directly and preferably annularly on the foil 5. With appropriate jamming can thus penetrate even with pierced film 5 (see Fig. 14) no dirt in the recesses 3.

In FIG. 13, especially in detail view B, it can be seen how the film 5 hugs the plug-in extension 6 of the drawer insert 4 like a bag. In Fig. C an alternative embodiment is shown. In essence, this shows the section A-A, that the drawer insert 4 preferably in the central region by the movable over the actuator 7 plug extension 6 can be additionally clamped, while the two shorter plug extensions 6 (as in detail view C) serve the additional stabilization or fixation.

14 shows the drawer insert 4 with a puncture tip 16 attached to the push-in extension 6, which punctures or tears the foil 5, as a result of which the tearing regions 17 of the foil are created and thus the foil 5 does not completely surround the push-in extension 6 in a bag-like manner, as in contrast thereto in Fig. 15 is shown. In this Fig. 15 it can be seen that the film 5 is stretched in the stretching region 19, whereby - as can not be seen in detail - this area 19 of the film 5 is thinner than the remaining film 5. If the plug-in extension 6 also allows additional jamming, the distance d between the plug-in extension 6 and the drawer bottom 2 is reduced. The distance d between the plug-in extension 6 and the drawer bottom 2 can be selected such that, depending on the film thickness of the film 5, a sufficient jamming is present when inserting the plug-in extension 6 into the recess 3 without requiring additional clamping, for example by means of an actuating element 7. The distance d may be selected to be small in order to ensure sufficient jamming already at the time of insertion or to be slightly larger in order to be able to perform the jamming by a mechanical or other distance reduction device after insertion.

Both in FIG. 14 and in FIG. 15, the drawer insert 4 is designed in the form of a positioning element 4c, which can be inserted into individual recesses 3 in the form of a pin and enables a simple subdivision adapted to the size of stored articles.

FIG. 16 shows various possibilities and embodiments of drawer inserts 4 with actuating elements 7 in a storage device or drawer 1.

Thus, this invention shows a drawer with perforated bottom and plug-in this hole bottom drawer inserts, as a major innovation between a drawer insert and perforated bottom film is considered that is sack-like depressible when attaching the drawer inserts on the plug extensions in the recesses, which preferably all holes or recesses in the drawer bottom are covered by the film or remain covered and thus the cleaning is facilitated. The Eindrückfähigkeit of the film is ensured by their extensibility and their elastic or at least viscoelastic property.
