Embodiment Construction

[0034] from Figure 1-Figure 4 , a box-shaped hinge part 1 of a conventional double-chain hinge can be seen. Figure 4 The base body 2 of the box-shaped hinge shown in , consists of a thin stamped sheet of metal. The edge of the center box 3 is provided with two approximately fan-shaped flange parts 4 on the connection side, which is approached by an approximately rectangular flange part 5, and the flange part 5 is provided with a clamping expander 7, 31. Perforation 6, which is shown as a pre-drilled hole for fastening. In some cases, when using a fastening component of the present invention, the pre-drilled hole does not have to be larger than, for example, 5mm (diameter).

[0035] in accordance with Figure 1-Figure 10 In the preferred embodiment, the dilator 7 consists of cylindrical pins spaced in the middle along a diametrical line. Thus, the cross-section of the individual dilator 7 is approximately semicircular. They are provided on their jacket surface with annul...

Abstract

A dowel-like fastening element for an assembly part to be fastened in a borehole, preferably for a furniture fitting, consists of two spreaders which can be inserted into the borehole in the compressed condition and can be spread by a part moved by a lever hinged to the assembly part. In order to be able to securely anchor the fastening element in a pre-drilled borehole only by actuation of the lever, the spreaders are parts of a peg which are separated by an axial slot and which are pivotally connected to the assembly part at their upper end regions. The moved part is a flat spreader part which can be pressed into the slot.

Description

technical field [0001] The invention relates to a pin-like fastener for an assembly to be fastened in a borehole, preferably as a furniture fitting, comprising two boreholes insertable in compression and hinged to the assembly by one The lever moves the part that extends the dilator. Background technique [0002] From DE2905378A1, people already know this kind of pin-shaped fastening element, and it is made up of the slotted expansion pin that is equipped with central drilling, is fastened on the flange-shaped part of box-shaped hinge box, and between hinge box and pin inserts After entering the pre-drilled hole, it expands because the pin fastened to the pivot arcuate portion hinged to the hinge box fits into the pin bore which narrows towards the pin end. Since the pins engage in pin bores which are adapted to the radius of rotation of the bow section on the cam track, these bores must then be designed relatively large, so that the parts of the pins separated by slots can...
