Abstract
Abstract The invention relates to a method for assembling together two parts of headlights or lights for automobile vehicles, the first of said parts being made of an inorganic material and the second of a thermoplastics material not able to be directly fixed to the first by adhesion, wherein a connection element is partially introduced into the second thermoplastics part so that a part of said element projects and acts as free anchoring element, and the two parts are then assembled together by the depositing of a layer of glue which, on the one hand, adheres to the first part and, on the other hand, completely covers the said free anchoring element.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
166 words
In a method for assembling together two parts of headlights or lights for automobile vehicles, the first of said parts being made of an inorganic material and the second of a thermoplastic material not able to be directly fixed to the first by adhesion, a metallic connection element is partially introduced into the second thermoplastic part so that a part of said element projects and acts as free anchoring element, and the two first and second parts are then assembled by the depositing of a layer of glue which, on the one hand, adheres to the first part and, on the other hand, completely covers the said free anchoring element which, after the glue has set, acts as mechanical connection between the two parts, and wherein, in order partially to introduce said connection element in the second part, said connection element is heated for predetermined length of time and a pressure is applied thereto with a view to causing it to penetrate in the thermoplastic material.
Claim 2
Dependent Claim
166 words
In a method for assembling together two parts of headlights or lights for automobile vehicles, the first of said parts being made of an inorganic material and the second of a thermoplastic material not able to be directly fixed to the first by adhesion, a metallic connection element is partially introduced into the second thermoplastic part so that a part of said element projects and acts as free anchoring element, and the two first and second parts are then assembled by the depositing of a layer of glue which, on the one hand, adheres to the first part and, on the other hand, completely covers the said free anchoring element which, after the glue has set, acts as mechanical connection between the two parts, and wherein, in order partially to introduce said connection element in the second part, said connection element is heated for predetermined length of time and a pressure is applied thereto with a view to causing it to penetrate in the thermoplastic material.
Claim 3
Dependent Claim
13 words
The method of claim 1, wherein the connection element used is a helix.
Claim 4
Dependent Claim
27 words
The method of claim 1, wherein a groove is made on the assembly surface of the second part, intended to facilitate the positioning of the connection element.
Claim 5
Dependent Claim
16 words
The method of claim 1, wherein the metallic connection element is heated by the resistance effect.
Claim 6
Dependent Claim
14 words
The method of claim 1, wherein the metallic connection element is heated by induction.
Claim 7
Dependent Claim
26 words
Application of the method of claim 1 to the assembling of reflectors or casings made of thermoplastics material selectively with glass or with metal support plates.
Claim 8
Independent Claim
110 words
The method of assembling and securing together two parts of headlights or lights for automotive vehicles, wherein the first part is of glass and has a peripheral flange and the second part is a concave reflective body of thermoplastic material having a peripheral assembly surface, comprising the following steps: (1) embedding and anchoring down into said peripheral assembly surface a circularly shaped metallic connector element, with a portion thereof projecting above said assembly surface defining a free anchoring element; (2) Depositing a layer of glue either on said peripheral flange or said peripheral assembly surface; (3) and bringing said flange and said surface together and embedding said free anchoring element.
