Means for mounting a fitting at a support

Claim 1

A hinge for attachment to a porous structure such as plasterboard, chipboard, and the like, comprising two halves each of which is defined as a body, the first body being U-shaped and having two parallel elastically deformable legs providing a support for a hinge pin common to both bodies, the first body being adapted to be mounted entirely counter-sunk in its structure, the second body being defined to fit between the legs and in one of its end positions being located inside the outer contour of the U-shaped body, both bodies at their surfaces turned to the structures at which they are to be attached being provided with at least two integral substantially cylindrical dowels arranged in a row, said dowels projecting perpendicularly from the surfaces and each being intended to enter one bore in the structure, the bores having substantially the same diameter as the diameter of the dowels, dowel having an axial slot extending from the free end thereof towards the body and an unslotted end portion for connection to the body, the axial slots in the dowels being located in parallel planes arranged perpendicularly to the plane of the row in which said dowels are arranged and said unslotted end portions of the dowels having an oval cross section, the short axis of which is substantially parallel to the plane of the axial slot, a wedge shaped member securely attached to the mouth of each axial slot, the attachment between the wedge shaped member and the dowel being rupturable when the dowel is forced into the bore and the free end of the wedge shaped member engages the bottom of the bore so that the member forces the axial slot of the dowel to expand, said bodies together with their dowels being in one piece of plastic material, at least one of the legs at its inner sides turned to each other being provided with one recess or projection each for cooperation with a complemental recess or projection at the end sides of the second body turned to the legs.
