Plastic drawer

The subject of the fire is a plastic drawer » which is composed of several ropes.

Drawers made of plastics are already known in various designs. They can be both one-piece and also be multi-part. They are used, for example, with Desks, organizational furniture, kitchen furniture and the like.

However, the plastic drawers known so far adhere The one-piece drawers, which are manufactured by injection molding or compression molding, still have some disadvantages due to the way they are manufactured, walls are thin and not very stable. however, this subsequently contradicts the funding Smooth outer walls as possible. In addition, one-piece, Finished drawers the large space required for shipping and storage is very disadvantageous ·. These disadvantages are true the multi-part drawers, which are usually made to fit » Sized extruded profiles and injection molded parts glued together

are eliminated, "but there are other chewing parts on, such as cutting the used string prqfile or Rods, the production of G-honor strings, the separate production of Eek connectors, dowels etc. and finally the careful assembly of all ropes »Man Although it also knows the production of stable side walls or the like by gluing two half-shells together with inner reinforcement ribs or, for example, the Use of side walls that have a plastic-coated chipboard core, but this does not reduce the amount of labor and material required.

These previous disadvantages are now replaced by this one Novel plastic drawer, which consists of several ! Divide is put together, eliminated «. This drawer is characterized by the fact that its rear wall and its side walls Ready-to-install injection-molded parts are connected at their ends to one another and to the Yorderwand Fastening elements, a base groove for the base plate, each formed by two protruding strips and a well-known guide groove for the slide rails of drawers have.ν

One possible embodiment of the novel drawer is shown in the pictures «

shown. The "two side walls 1a and 1b are initially plugged together by the invisible wale-tail-shaped lut-tongue connection with the rear wall 2 to form a U-shaped frame, in the circumferential bottom groove 7 of which the bottom 11 is inserted. The circumferential bottom groove 7 is thereby; two protruding strips each formed, which are also injection-molded _{onto the injection molded parts 1a, 1b f} 2. The assembly of the drawer is completed by attaching the front wall or panel (not shown) 1b are molded on, two pre-fabricated dowel holes are driven into the front wall or panel in a known manner, in which they are held due to their transverse ribbing. This also ensures the final and firm cohesion of the finished drawer »The bottom 11 can no longer fall forward out of the hat of the tJ-shaped frame and b The two previously free ends of the IJ-shaped frame are perfectly tied up as a result of the dowel connection with the Yorderwand or the panel. With the tightest possible fit of both the dowels and the wale-tail-shaped corner connections, the greatest possible angular accuracy of the corners at the upper edges of the drawer can be achieved. This makes it possible to reduce the sensitivity to uses that is known from an open box.

In! Figure 2 is a dovetail-shaped corner joint shown with peder and groove 3, 4 between the side wall 1 a and the rear wall 2. This corner joint is for the on

force relationships occurring in a drawer firm enough to ensure that the corner is sufficiently angular. The also required Yerwindungssteifigkeit the side and rear walls 1 a, 2 is through their training reached as hollow profile parts with crossbars 8 and 9 »

Finally, in FIG. 3 there is also a deil section through the Side wall 1a shown in which the guide groove β for the supporting slide rails in the upper wall part and in the lower wall part the receiving groove 7 for the base plate 11 is visible. the Side wall 1 a is shown here with a cavity 10 that is open at the bottom.

Since hollow profile rods that are open at the bottom are not so large ! Have strength like bars with a closed profile, you can finally in the case of greater strength requirements also for the side walls 1a, 1b and for the rear wall 2 in see Use closed profiles, which, for example, have a dense outer skin and a cellular core from a card have foamed plastic. So the two of them can Demands for greater strength and smooth outer surfaces to be met.

In addition, since the novel drawers can be assembled very easily and without special tools, can their individual parts can be stored and dispatched without taking up too much space.
