Description

The invention relates to a fitting made of plastic for releasably connecting furniture parts, the is provided with a arranged in or on the one furniture part rotatable disc, which in a hooks into the other furniture part inserted dowel.

There are already various embodiments of fittings for connecting furniture parts known by means of a rotatable disc. In one embodiment, the rotatable disc is through its eccentric suspension suitable for pulling furniture parts together by turning them to the right as well as to the left, whereby the disc can be rotated without tools.

In this known fitting, a metal disc is used, the bent outer edge as The tightening surface is used, which is attached to the other furniture part with a hook that reaches behind the tightening surface cooperates. In the case of a centrally suspended disc, the known design is the However, the tightening surface cannot be used.

According to the invention, a fitting made of plastic is used for releasable connection of furniture parts, which as a standard model are similar for both clockwise and counter-clockwise rotation is determined, the attraction surface is formed in that on the rotatable disc a sickle-shaped, after Both ends of the same sloping projection is arranged, the inner surface of which as an eccentric tightening surface cooperates with the hook-shaped run-up nose of the dowel in a known manner.

The plastic fitting is made without the use of metal for production and fastening manufactured and used. There are no tools whatsoever for attachment or operation necessary. The few parts of the fitting can be made from thermoplastic or duroplastic in a single operation Mass with the possibility of coloring according to the wood tone of the furniture be glued in after machine pre-drilling.

The rotatable disc can be inserted loosely in a known manner into a bore of the furniture part, they but can also be mounted on an axis glued into the furniture. To cover the borehole if the pane is expedient with a fold-like protruding edge which is also already common, which is advantageously knurled to enable the disc to be turned easily by hand without tools. The washer and dowel can be pushed through with a recess to accommodate the dowel provided capsule be coverable.

Fig. 6 shows a vertical section of the fitting arranged in the furniture parts according to the line CD in Fig. 5 with a capsule for covering the fitting parts.

To install the fitting according to the first embodiment (Fig. Ι to 4) are first the Hole 1 in the furniture part 5 and the holes 2 and 3 in the furniture part 7 according to the dimensions of the fitting parts dowel 4 and washer 6 are pre-drilled so that the shaft of the dowel 4 seated tightly in the bore 1 of the furniture part 5, the disc 6 rotatably inserted into the bore 3 and the Dowel 4 can be inserted into the bore 2 with sufficient space. For a permanent connection the furniture parts 5 and 7 is first the disc 6 with the molded sickle-shaped projection 8 inwardly inserted into the bore 3 that the molded hook 10 on the dowel 4 in the free recess 9 of the projection 8 of the disc 6 is located. Then the disc is by hand on the corrugated edge 11 rotated to the left or right. Here, the sickle-shaped projection 8 engages with the The sloping sliding surface 12 in the hook 10 formed in the dowel 4 pulls the furniture parts 5 and 7 together and at the same time causes the

Fold edge 13 against the front of the furniture part 7 to cover the hole 3.

In the second embodiment (Fig. 5 and 6) is a differently shaped, also having a sickle-shaped projection 14 and also with a Disc 15 provided with a bore 18 is rotatably mounted on a flange 17 glued into the furniture part 16. Here, to cover the fitting parts, namely the dowel 19 and the washer 15 with bolts 17, a capsule 20, which is provided with a recess 21 for receiving the dowel 19, is pushed over it will.
