Abstract
Abstract An edge protector adapted to be applied over the edges of metal, glass or other sheet materials to prevent damage to the edges of said sheets, and to prevent damage by said edges to adjacent sheets, consisting of continuously extruded section of resilient plastic including in cross-sectional contour, a U-shaped clip portion adapted to engage frictionally therein the edge portion of a sheet, a broad shock-absorbing head portion adjacent the closed edge of the clip portion, and a thin, narrow neck interconnecting the clip and head portions whereby the head portion can tilt laterally with respect to the clip portion.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
263 words
An edge protector comprising an elongated member formed of a flexible, resilient plastic material having only moderately efficient recovery characteristics from deforming strains, said protector being of one-piece, homogenous structure and of uniform cross-sectional contour throughout its length, and including the following elements: a. an elongated clip member of generally U-shaped crosssectional contour having generally parallel, spaced-apart side walls connected by a base portion, and adapted to receive therein the edge portion of a sheet article of a thickness for which the protector is designed, said side walls being spaced apart by a distance greater than the thickness of said sheet article and having yieldable inward projections adapted to engage and grip said sheet aritcle therebetween, and to center said sheet article between said side walls, b. an elongated head member longitudinally coextensive with said clip member and disposed adjacent and parallel to the base portion of said clip member, and c. a narrow neck joining said head and clip members and being sufficiently thin to constitute a flexible hinge permitting relative pivotal movement between said head and clip members about an axis parallel to and intermediate said members, said neck being centered between the planes of said side walls, and the thickness of said neck, in a plane normal to said side walls, being less than the thickness of said side walls, less than the space between said side walls, and less than the thickness of said sheet article, whereby a shock load transmitted to said clip member by said neck will be delivered to the edge surface of said sheet article.
Claim 2
Dependent Claim

An edge protector comprising an elongated member formed of a flexible, resilient plastic material having only moderately efficient recovery characteristics from deforming strains, said protector being of one-piece, homogenous structure and of uniform cross-sectional contour throughout its length, and including the following elements: a. an elongated clip member of generally U-shaped crosssectional contour having generally parallel, spaced-apart side walls connected by a base portion, and adapted to receive therein the edge portion of a sheet article of a thickness for which the protector is designed, said side walls being spaced apart by a distance greater than the thickness of said sheet article and having yieldable inward projections adapted to engage and grip said sheet aritcle therebetween, and to center said sheet article between said side walls, b. an elongated head member longitudinally coextensive with said clip member and disposed adjacent and parallel to the base portion of said clip member, and c. a narrow neck joining said head and clip members and being sufficiently thin to constitute a flexible hinge permitting relative pivotal movement between said head and clip members about an axis parallel to and intermediate said members, said neck being centered between the planes of said side walls, and the thickness of said neck, in a plane normal to said side walls, being less than the thickness of said side walls, less than the space between said side walls, and less than the thickness of said sheet article, whereby a shock load transmitted to said clip member by said neck will be delivered to the edge surface of said sheet article.
Claim 3
Dependent Claim
49 words
An edge protector as recited in claim 1 wherein said head member comprises a generally planar strip with its plane normally at generally right angles to the planes of the side walls of said clip, and wherein the surface of said head distal from said clip is transversely concave.
Claim 4
Dependent Claim
76 words
An edge protector as recited in claim 1 wherein said clip member side walls extend unequal distances from said base connecting portion, and wherein said inward projections of said side walls include a pair of inwardly projecting lips carried respectively by the side walls, said lips being equidistant from said base connecting portion whereby to engage each other normally to preserve a fixed spacing between said side walls, and being inclined toward said base connecting portion.
Claim 5
Dependent Claim
88 words
An edge protector as recited in claim 3 wherein said inward projections of said side walls additionally include one or more resilient flaps projecting inwardly from each side wall intermediate the lip thereof and said connecting base portion, said flaps extending more than one-half of the normal spacing between said side walls, being inclined toward said base connecting portion, and being disposed at graduated distances from said base connecting portion whereby the flaps of one side wall will normally interdigitate with the flaps of the other side wall.
Claim 6
Dependent Claim
50 words
An edge protector as recited in claim 4 wherein one of said side walls has a lesser number of said flaps than the other side wall, and wherein the flaps carried by said one side wall are thicker and less flexible than the flaps carried by said other side wall.
