WIRE DRAWER

Abstract: Wire drawer with a ribbonshaped upper rim (11). To this rim, a guiding roller (14) is attached at each of two adjacent corners. To carry this roller, the rim is bent down at the corner to make a lug (12) perpendicular to the plane of the rim. The axel (15) of the roller is attached in a central area of this lug to hold the roller within the outer edge (17) of the rim extending above its upper level.

Description: Wire drawer The invention relates to wire drawers as described in the introductory part of claim 1, mainly for use in wardrobe cabinets. Background: Wire baskets are used as drawers carried in slides attaced in cabinets, in carrying frames and similar structures. It is previously known to attach a pair of slides, each with a guiding roller, at opposite edges of a frame made of steel ribbon. This design requires a relatively high mass of additional material and causes an increase in height which in some cases is unsuitable and undesirable. This design requires additional equipment and additional manufacturing steps. Thus it is desirable to have a wire basket which lowers the costs. The main object of the invention is to create a wire drawer which is less expensive to manufacture than prior art drawers. It is a particular object to create a wire drawer with less parts and which can be manufactured with less steps of work than prior art wire drawers with guiding rollers. The invention The invention is described in claim 1, while particularly advantageous features are described in the subclaims. This wire drawer reduces the material consumtion to a minimum, while the manufacturing operations to mount the guiding rollers are simple and can be robotized. Example The invention is further described with reference to the drawings illustrating an embodyment, wherein Fig. 1 shows a perspective view of a corner of a wire drawer, while Fig. 2 shows the corner of Fig. 1 in a plane view from above. The wire drawer 10 in the example is provided with a rectangular frame 11 of steel ribbon arranged in the frame plane, the ends being joined by welding. At two adjacent corners the frame is bent downward, making two mutually parallel lugs 12 extending downward from the plane of the frame with the inner sides at the inner edge of the frame. This creates a notch at the edge of the frame as shown at 13 in. Fig. 2. In this notch, a guiding roller 14 is arranged, pivotably journalled on an axle 15. This is protruding a bore in the lug 12 and is riveted thereto. The axle 15 is arranged centrally on the lug, making the guiding roller extend above the fram 11 and under the lug 12. The axle 15 may be pressed or cut with flanges 15A and provided with a washer 15B at the free end. The lugs 12 are bent downward with one edge (18) arranged niore distant from the corner than the other (19). This allows the attacment of the guiding roller 14 with no additional elements and with easy operations. Additionally, the guiding rollers 14 will have an advantageous arrangement at the corner of the wire drawer 10, without protruding excessionally outside the drawer in any direction. This gives advantages at stacking and transport. The invention can also be utilized for drwaers of other materials than wire. It can be used for sheet drawers of metal and plastic in combination, with an upper rim or a flange. The invention allows the guiding rollers at the front of the cabinet or carrying structure to roll directly against the frame 11.

Claims: Claims: 1. Improvement on basket intended for use as drawer in a cabinet or similar structure, with an upper rectangular rim or flange (11) of ribbon material on a meshed wire or sheet structure (16), this rim being in a common plane, and on two adjoining comers being provided with guiding rollers (14) intended to cooperate with an individual guiding rail carried by the cabinet or the similar structure, characterized in - that the ribbon rim at two adjoining comer is bent down to create a lug (12) perpendicular to the rim plane, - that the axle (15) of the guiding roller is attached centrally on this lug, and - that the guiding roller is arranged to protrude over the rim. 2. Improvement according to claim 1, characterized in that each lug (12) is bent downward with a first bending edge (18) at a. longer distance from the comer, than the second bending edge (19). 3. Improvement according to claim 1, characterized in that the lug (12) is bent downward to be arranged at the inner side of the rim (11). 4. Improvement according to claim 1, characterized in that the axis of the axle (15) is arranged at a lower level than the lower side of the rim (11).
