1477206 Vehicle bumpers ROBIN PRODUCTS CO 17 May 1974 [21 May 1973] 21954/74 Heading B7J [Also in Division B6] An elongate resilient trim member 26 suitable for mounting on vehicle panels and bumpers for ornamental and protecting purposes, has a base surface 32 adapted to be mounted on a support surface 20 having one or more apertures therein, and one or more integral connectors 40 or 140 projecting from said base surface and engageable in the apertures in the support surface for mounting the trim therein, the connector having opposing substantially parallel side walls 42 with a detent 46 on one or both side walls, having a camming surface 50 inclined to the projecting axis of the connector and facing away from the plane of the base surface, and a locking surface 52 also inclined to the said axis and facing towards the plane of the base surface, there being resiliently collapsible further walls 44 between said side walls, the collapsible walls being collapsible between the side walls upon insertion of the connector into an aperture in the support surface. The trim member may be a moulding made of resilient polymeric material, e.g. high density polyethylene. The camming surface and locking surface are preferably spaced apart by a shoulder surface 54. The collapsible walls are integral with the side walls, and are resiliently collapsible by virtue of their concave shape and the flexible nature of the material from which they are formed. On insertion of the connector into an aperture, the walls 44 collapse inwardly under pressure from the side walls 42 from the action of the camming surface against the edge of the aperture, and then recover after insertion beyond the shoulder 54 to cause the locking surface to engage against the inner face of the support surface, as shown in Fig. 4. The trim member may provide a trim assembly for a bumper 20 with over-riders 22, consisting of a central trim 26, two end trims 28 and over-rider trims 30. Connectors as described, moulded integrally with the trim strips, are engaged in apertures 34 and 36 in the bumper and over-riders for mounting the trim. In a preferred embodiment, the apertures 34 are longer than the corresponding width of the connectors while one aperture 36 closely conforms to the dimensions of the connector (Fig. 2) to accurately locate and centralize the trim on the support. This arrangement allows the trim to be fitted to a curved or angled surface, and also allows for manufacturing tolerance variations. |
