Description

Drawer assembly and wheel puller rails for it

The object of the invention is an assembly of drawers and pull-out guides thereto, preferably drawers for household refrigerators.

Technical Problem [002] The technical problem solved by the invention is how to design such a set of drawers and wheel pullers for them, which will allow any user to easily and without tools remove the moving part of the wheel guides from the drawer after having the drawer with the moving part of the wheels guide removed from the space in which it is installed, preferably from the refrigerator, and then reinstalling the drawer to its original position in a simple manner, without special knowledge or without tools. In particular, there is a need to temporarily remove and reinsert the drawer and to separate the movable part of the rails from it while regularly cleaning the drawer and the room in which it is located, e.g. when cleaning the usable interior of the refrigerator. The construction of this set is intended to provide a market-friendly price.

BACKGROUND OF THE INVENTION [003] The known assemblies of this kind are made of arbitrary drawers and are intended for each type of drawbar of wheel guides.

34907. doc / X-07 / Vr [004] According to DE 298 17 743 Ul (BSH), guides are known which allow the movable guide to be disengaged from the drawer because of a built-in spring connecting the movable part of the rail and the drawer. The disadvantage of this solution is the high cost, so it is justified to install only in high-end products.

[005] Otherwise, a cost effective solution of this screw-based assembly is known. The disadvantage of this solution is that it is not suitable for regular separation during cleaning.

Solution to a Technical Problem [006] The technical problem described is solved by an assembly of drawers and pull-out guides for them, preferably drawers for household refrigerators according to the invention, characterized in that elastic coupling elements are mounted on the pull-out part of large-series wheel pull-out guides and are on the drawers in the area of contact with the pull-out portion of the guides, the bearings are designed for these fasteners, such that the fasteners positioned in these bearings position the drawer relative to the guides and at the same time fix the drawer on the rails so that the drawer is unstable while in use on the rails. only by special pushing of the drawer in a direction that is excluded during regular use of the drawer, the user can easily separate the drawer from the rails due to the elastic deformation caused by the user's direct thrust on the drawer of the coupling element. Assembling of drawers and guides is provided in terms of the reverse steps of the process as just described.

[007] The invention is explained in more detail based on the description of the embodiment and the drawings in which FIG. 1 is a cross-sectional view of the assembly according to the invention; 2 is a perspective view of the latch according to the invention mounted on the guides,

34907.doc / X-07 / Vr fig. 3 drawer detail with insert mounted on the rails.

[008] The assembly of drawers and pull-out guides thereto, preferably drawers for household refrigerators, is made of any known wheel pull-out guides I, consisting of a fixed part 2, which is in any way positioned in the object 3 intended to receive drawers 4, and the extraction portion 5, which is axially movable in the portion 2 and is mounted on the drawer 4 by means of coupling elements 6.

[009] The guides 1 in a preferred embodiment use such guides, the extraction portion 5 of which is provided with a contact belt 7, which is intended to receive any horizontally extending lateral portion 8 of the drawer 4. As a lateral horizontal portion 8, the meant belt at the bottom 9 of the drawer 4 or the horizontal belt of the side wall 10 of the drawer 4.

[0010] There are several, and in principle at least one, connecting element 6, which is formed from a body 11 containing a part 12 for preferentially screwing the element 6 to the belt 7 of the guide 1, on the contacting belt 7 of each guide 1. at least one, preferably two snaps 13 with a tooth 14, wherein the snaps 13 are designed as resilient brackets.

[0011] Drawer 4, which is intended to be mounted on guides 1, is made on horizontally extending lateral portions 8 with slots 15 for connecting elements 6, each tray 15 having an edge 16 into which it latches due to its shape and elasticity of the teeth 14 of the individual latch 13 of the coupling element 6.

[0012] The cantilever shape of the coupling elements 6 ensures the positioning of the locking elements 6 in the bays 15, so that the latches 13 fit into the bays 15, so that they provide a fixed connection between the guide 1 and the drawers 4. The edges 16 of the bays 15 and the teeth 14 of the locks 13 are designed as follows to be theirs

34907.doc / X-07 / Vr interconnects when a force is applied in the direction of the longitudinal axis of the latches 13, i.e. , when the user acts force perpendicularly to the bottom 9 of drawer 4 in the direction of the upper part of drawer 4.

[0013] The beds 15 in the side portions 8 of the drawer 4 are preferably configured to contain openings 18 for the discharge of the cleaning fluid regardless of the slope of the drawer 4.

[0014] Preferably, the coupling elements 6 are made of thermoplastic materials, as well as drawers 4, while the guides 1 are metal. The drawers 4 may also be made of other materials, for which manufacturing procedures and further detailed shapes of the beds 15 are adapted, if necessary.

[0015] It is understood that one of skill in the art may, on the basis of knowledge of the above invention and the presented embodiment, conceive other embodiments without circumventing the features of the invention as defined in the following claims.
