Claims

Finally, a dowel plate with two molded patent claims: th dowels have become known, in whose dowel

1. Dowel with an asymmetrically designed part towards the openings that can be inserted into the dowel hole The end of the dowel has a slotted dowel shank, which occupies itself when it is rotated around it 5 th degree of angle tapering conically towards the end of the dowel spreads the dowel in question. Dowel opening and with one with a head Here it is disadvantageous that the spreading is not provided expansion pin, which expansion joint is done with foolproof wed the relevant angle of Axial movement that can be carried out externally is kept relatively precisely in terms of amount the dowel opening towards the end of the dowel must have this. In addition, there is always a special lift mechanism, characterized in that * ° stuff, for example an inner key for the the expansion pin (5) with its head to the dowel auxiliary part is necessary. This special key can the end is arranged pointing that the dowels are lost, so that when machining euie Opening (7) a receptacle (8) for the head (6) delay occurs.

in which it lies on the expanding pin shaft side of the invention, starting from a dowel by means of a shoulder on the dowel and on the type mentioned at the outset, the underlying task is to further develop the free, other side by means of the conical design, that the expansion joint of the part (9) of the dowel opening (9) can be axially supported without being lost,
ten is. The invention is to solve this problem

2. Dowel according to claim 1, characterized in that the expanding pin with draws that on the conical part (9) of "his head is arranged pointing to the dowel end Dowel opening (7) adjoins a constriction (10), is that the dowel opening is a receptacle for the whose diameter has when the head is not inserted, in which this on the expanding pin shaft expanding pin (6) is smaller than the currently formed side by means of a shoulder on the dowel and on the dete shaft of the expanding pin. free, other side by means of the conical

3. Dowel according to claim 1 or 2, characterized in that * 5 th part of the dowel opening is held axially.
characterized that in the direction of the dowel, the expansion pin is held axially in a dowel on the conical part (9) of the invention via the receptacle, dowel opening (7) an enlargement (11) so that a corresponding The pre-assembled dowel also closes, which in the expanded state of the dowel cannot be lost during transport, takes up the head (6). 30 During processing, the expanding pin only needs

4. Dowels according to one of the preceding Hch by hand or with a suitable tool, Claims, characterized in that, for example, a hammer, into the dowel opening Shoulder the end of a tightly to be driven into the expanding pin, so that the expanding pin Shank adjacent constriction (13) is. spreads the dowel.

35 For attaching hinges and the like

Fogging can be several, z. B. two according to the invention Dowels can be arranged on a plate.

The invention relates to a dowel with for in. In an embodiment of the invention it is before-dowel hole usable dowel end is slotted towards, if the conical part of the dowel dowel shaft, with an opening conically towards the end of the plug, a constriction is connected, the tapering of which Dowel opening and with a knife when the expansion joint is not inserted is smaller Head provided spreading hip, which spreading hip in the case of the straight shaft of the expanding pin, Axial movement that can be carried out from the outside in the The expansion joint is then very easy to produce, Dowel opening towards the end of the dowel spreads it. when its shaft is straight.

Such a dowel is known. At this 45 to prevent the spreader pin at
