ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to mounting devices involving an externally ribbed or toothed anchor, adapted for mounting of hardware for furniture, in particular hinges.
In the hardware field for furniture, the problem of providing quick, safe and sometimes removable fastening to the different hardware elements is known. Hinges formed of a base to be fastened to the piece of furniture and a bowl to be fastened to the door are a typical example thereof. Use of such anchors has been proposed. However, the proposed solutions are generally complicated, expensive, of slow use and sometimes poor security.
It is a general object of the present invention to eliminate the above mentioned drawbacks, by providing anchor fasteners that are quick, unexpensive and safe.
SUMMARY OF THE INVENTION
In view of the above object, in accordance with the invention an expansion fastener has been conceived for hardware elements for furniture which comprises a ribbed anchor body made of a material which is at least radially flexible and in which an insert is fitted, which insert has a cam surface sliding on a corresponding cam surface in the anchor body to cause radial expansion of same on its movement through pulling means in an axial direction relative to the anchor between a first rest position and a second expansion position, characterised in that the insert comprises a fitting end radially extending in a region free from the anchor body, the insert being secured to the pulling means to be susceptible of inclination in the extension direction of said end, on its axial movement towards the expansion position the insert sliding on the cam surface to receive a thrust for inclination and move said end outwardly of the anchor and towards the pulling direction.
