Abstract

An edge protector for a sheet of glass or the like comprising an integral, dual-durometer, co-extruded channel having rigid and soft portions. The rigid portion comprises a channel having an internally generally flat central portion and legs extending convergently from edges of the central portion and terminating in reversely curved, divergent edge portions providing confronting oppositely curved surfaces spaced from the central portion. The soft portion comprises deformable gripping pads formed integrally by co-extrusion on said confronting surfaces and providing confronting, deformable gripping surfaces for conformably gripping therebetween, with surface-to-surface contact, exterior parallel surfaces of a glass sheet or the like adjacent the edge of the sheet with the latter receivable in confronting relationship to the internally generally flat central portion of the protector.

Claims

1. An edge protector for a sheet of glass or the like comprising an integral, dual-durometer, co-extruded channel having rigid and soft portions, the rigid portion comprising a channel having an internally generally flat central portion and legs extending convergently from edges of the central portion and terminating in reversely curved, divergent edge portions providing confronting oppositely curved surfaces spaced from the central portion, the soft portion comprising deformable gripping pads formed integrally by co-extrusion on said confronting surfaces and providing confronting, deformable gripping surfaces for conformably gripping therebetween, with surface-to-surface contact, exterior parallel surfaces of a glass sheet or the like adjacent the edge of the sheet with the latter receivable in confronting relationship to the internally generally flat central portion of the protector.

2. The edge protector of claim 1 wherein the rigid portion is so configured as to provide the legs with a range of elastic movement toward and away from one another and wherein the gripping surfaces of the gripping pads are formed with oppositely curved, generally cylindrical gripping surfaces so as to continually provide thusly-curved proximate deformable gripping surfaces to parallel surfaces of a glass sheet or the like adjacent its edge as the legs are moved together and apart.

3. The edge protector of claim 2 in which said generally cylindrically curved gripping surfaces of the gripping pads are provided with longitudinally extending ribs.

4. The edge protector of claims 1 or 2 in which the legs and central portion of the rigid channel are of uniform thickness.

5. The edge protector of claim 1 in which the central portion includes a smooth exterior surface.
