Abstract
The invention relates to an assemblage of two pieces of bodywork (1, 2) each having a flange (5, 6) for pressing against the flange of the other piece. Each flange carries at least one tongue (11, 12) extending towards the other piece. A fastener member (20) is suitable for engaging around the tongues so to prevent them from moving relative to one another once said two pieces of bodywork are in a predetermined position in which they are united flange against flange. The invention also provides the pieces of bodywork constituting said assemblage.
Claims17
1/ An assemblage of two pieces of bodywork (1, 2, 2′, 40,41, 70, 71, 90, 91) each piece having an outside face and a flange (5, 6, 6′, 45, 46, 75, 92, 93) substantially perpendicular to said outside face and intended for pressing against the flange of the other piece, the assemblage being characterized in that each flange carries at least one tongue (11, 12, 12′, 47, 48, 76, 94) extending towards the other piece beyond the flange of said other piece, the assemblage further comprising a fastener member (20, 20′, 42, 72, 80, 96) suitable for engaging around the tongues and for preventing them from moving relative to one another when in a predetermined position in which the two pieces of bodywork are united flange against flange.
2/ An assemblage according to claim 1, characterized in that each flange (5, 5′, 6, 45, 46, 75, 92, 93) carries a plurality of tongues (11, 12, 12′, 47, 48, 76, 94), each of which can be engaged between two tongues of the other flange.
3/ An assemblage according to claim 2, characterized in that the tongues of one flange are spaced apart in pairs by a distance (18) substantially equal to the width of the tongue on the other flange that is to be interposed between them.
4/ An assemblage according to claim 2 or claim 3, characterized in that the free end of each tongue (11, 12) tapers making it easier to insert between two tongues of the other flange.
5/ An assemblage according to any one of claims 1 to 4, characterized in that each tongue (11, 12, 12′, 47, 48, 94) is plane and extends substantially perpendicularly to its flange.
6/ An assemblage according to any one of claims 1 to 5, characterized in that the tongues are oriented in such a manner that the two pieces of bodywork assemble together along the longitudinal direction of the vehicle.
7/ An assemblage according to any one of claims 1 to 6, characterized in that the fastener member (20, 20′, 42, 72, 80, 96) has at least one open cavity enabling it to cover two tongues together with at least a portion of the two flanges of two assembled-together pieces, said cavity having at least one bearing point against each tongue and at least one bearing point against each flange.
8/ An assemblage according to claim 7, characterized in that the fastener member (20, 20′) is a rigid section member of cross-section in register with the cavity that defines internally at least a portion of the outlines of the cross-sections of the tongues and at least a portion of the outlines of the cross-sections of the flanges of the two assembled-together pieces.
9/ An assemblage according to claim 7, characterized in that the fastener member (42, 72, 80, 96) is a resilient section member having two branches defining the cavity and suitable for splaying apart from each other by elastic deformation to allow the two tongues to pass through the opening into the cavity.
10/ An assemblage according to any one of claims 1 to 9, characterized in that at least one of the pieces (41) carries means (58) for snap-fastening with the fastener member (42) so as to hold the fastener member on the tongues (47, 48) of the two flanges (45, 46).
11/ An assemblage according to any one of claims 1 to 10, characterized in that at least one of the two pieces (1, 2, 40, 41, 70, 71, 90, 91) is made of a thermoplastic or thermosetting plastics material.
12/ An assemblage according to any one of claims 1 to 11, characterized in that the fastener member (20, 20′, 42, 72, 80) is made of plastics material.
13/ A piece of bodywork having an outside face and a flange substantially perpendicular to said outside face, the piece of bodywork being characterized in that said flange carries at least one tongue extending transversely to said flange and projecting beyond said outside face.
14/ A piece of bodywork according to claim 13, characterized in that it has a plurality of tongues spaced apart in pairs.
15/ A piece of bodywork according to claim 13 or claim 14, characterized in that it includes means for snap-fastening with a fastener member engaged on its flange.
16/ A motor vehicle bumper in accordance with claim 13, 14, or 15.
17/ A motor vehicle fender in accordance with claim 13, 14, or 15.
