Embodiment Construction

[0013] see figure 1 , numeral 10 denotes a fastening element according to the invention. The fastening element 10 is formed from a monolithic body of metallic material, for example steel, provided with threaded holes inside. The fastening element 10 is inserted and fastened in metal profiles for window and door frames. The profile 12 has an outer wall 14 with a smooth outer surface and at least one inner wall 16 parallel to the outer wall 14 . As a preliminary operation before inserting the fastening element 10 , the installer drills concentric through-holes 18 and 20 of equal diameter in the walls 14 , 16 .

[0014] The fastening element 10 has a cylindrical central portion 22 of constant diameter and two end portions 24 , 26 . The diameter of the holes 18 , 20 is slightly smaller than the diameter of the cylindrical central portion 22 . The end portion 24 serves as an insertion portion and has a frustoconical shape with a larger diameter equal to that of the cylindrical ...

Abstract

Elements for fastening accessories to metal window and door frames comprising: a monolithic metal body having a cylindrical central portion with an internally threaded hole; an insert portion having a frustoconical shape with a A diameter reduced from the diameter of the cylindrical central portion; a stop portion comprising a circumferential throat bounded by a shoulder having an outer diameter greater than the diameter of the cylindrical central portion, the shoulder The outer diameter of the cylindrical central part is connected to the cylindrical central part by a frusto-conical section; a first series of longitudinal through grooves, the grooves extend part of the length of the cylindrical central part and the insertion part and the the grooves define a first portion deformable radially inwardly relative to the undeformed rest configuration; and a second series of longitudinal through grooves extending a portion of the length of the cylindrical central portion and a stop portion and The groove forms a second portion elastically deformable inwardly relative to the undeformed rest configuration.

Description

technical field [0001] The invention relates to an element for fastening accessories back on metal windows and doors. [0002] The invention has been developed in particular for fastening hinges to metal window or door frames, usually made of aluminum or similar alloys. However, the invention is not limited to this specific field of application. Background technique [0003] In order to solve the problem of fastening hinges to window or door frames with considerable weight, the use of internally threaded metal pins is becoming more and more common; such pins are inserted and fastened in holes in metal profiles, so The above-mentioned metal profiles form the fixed frame and movable frame of the window or door. Once the pins are inserted into the corresponding holes, they allow the use of screws for fastening the hinge. [0004] A first example of a dowel suitable for this purpose is described in document US-B-6702534, which discloses a spreader dowel with a cylindrical sle...
