Abstract
The invention relates to an assemblage of two pieces of bodywork (101, 102) each having a flange (107, 114) for coming into contact with the flange of the other piece, the flange of a first piece having a slot while the flange (114) of a second piece carries a tenon (103, 104, 105) presenting an engagement shape and extending towards the first piece. The assemblage also comprises a fastener member (106) for taking up a position against the flange of the first piece and which has an engagement shape complementary to that of the tenon so as to engage therewith. The invention also provides a piece of bodywork belonging to such an assemblage.
Claims15
1/ An assemblage of two pieces of bodywork (1, 2, 101, 102) each having a flange (4, 8) for coming into contact via its outside face with the flange (8, 4) of the other piece, the flange (4, 107) of a first one of the pieces including a slot (17) passing through the thickness of the flange to its inside face, while the flange (8, 114) of a second one of the pieces carries a tenon (9, 10, 103, 104, 105) having an engagement shape and extending towards the first piece (1, 101), the tenon being suitable for penetrating into said slot (17) so as to project from the inside face of the flange (4, 107) of the first piece, the assemblage further comprising a fastener member (21, 106) which is suitable for positioning against the inside face of the flange (4, 107) of the first piece and which has an engagement shape complementary to that of the tenon (9, 10, 103, 104, 105) for engaging therewith.
2/ An assemblage according to claim 1, in which the engagement shapes present a T-shaped section.
3/ An assemblage according to claim 1, in which the first piece (1, 101) has a plurality of slots (17) and in which the second piece (2, 102) has a plurality of tenons (9, 10, 103, 104, 105) positioned to be in register with the slots when the two pieces are brought together.
4/ An assemblage according to claim 1, in which the tenon(s) (9, 10, 103, 104, 105) and the fastener member (21, 106) engage in a direction that is substantially parallel to the flanges (4, 8, 107, 114).
5/ An assemblage according to claim 1, in which the first piece (101) has guide shapes (111) on the inside face of its flange (107), which guide shapes support the fastener member (106) over an appropriate stroke along the flanges (107, 114) of the pieces to enable it to engage the tenons (103, 104, 105).
6/ An assemblage according to claim 4, in which the tenons (9, 10, 103, 104, 105) and the fastener member (21, 106) are arranged in such a manner that said fastener member is engaged with all of the tenons simultaneously.
7/ An assemblage according to claim 1, in which the fastener member (106) is suitable for taking up not only an engaged position with the tenons (103, 104, 105), but also a pre-engagement position in which it is located against the inside face of the flange (107) of the first piece (101) but is not yet engaged with the tenons, transfer from said pre-engagement position to the engagement position being performed by moving the member in translation along a stroke slightly longer than the engagement length of the tenons (103, 104, 105).
8/ An assemblage according to claim 1, in which one of the pieces (1, 101) has centering orifices (19) positioned in precise manner in its flange (4, 107), and the other piece (2, 102) has centering pegs (15, 16) for engaging with little clearance in said centering orifices (19).
9/ An assemblage according to claim 1, in which at least one of said pieces (1, 101) has an opening (6, 108) at the end of its flange (4, 107) for engaging the fastener member (21, 106).
10/ An assemblage according to claim 1, in which at least one of the pieces of bodywork (1, 2, 101, 102) is made of plastics material.
11/ An assemblage according to claim 1, in which the fastener member (21, 106) is made of plastics material.
12/ An assemblage according to claim 1, in which one of the pieces is a fender and the other is a bumper element.
13/ A piece of bodywork having a flange (8, 114) for coming into contact with the flange of another piece of bodywork, said piece of bodywork carrying a tenon (9, 10, 103, 104, 105) presenting an engagement shape and projecting from its flange (8, 114).
14/ A bodywork fender constituting the piece of bodywork according to claim 13.
15/ A bumper element constituting the piece of bodywork of claim 13.
