Abstract
Abstract A corner protector, such as for protecting the corners of plate or board-like articles, is made as a single moulding of plastics material and comprises top and bottom triangular planar parts, to slide over respective top and bottom parallel faces of the board, and wall parts; edges of all said parts defining a mouth to allow the protector to be applied to a corner of the board, the wall parts including resilient means to allow the top and bottom planar parts to move apart elastically. The resilient means may comprise springs of folded strand form lying in the plane of the wall parts. Preferably, the corner edge of the protector which abuts the corner edge of the board is thickened and rounded by a protuberance of cylindrical form.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
111 words
In a corner protector, for the corner of an article having upper and lower parallel faces and adjacent edge faces, comprising floor and ceiling planar parts to slide over respective ones of said parallel faces and wall parts extending between the floor and ceiling parts to contact respective ones of said edge faces, the improvement in that the wall parts are defined by flanges on the ceiling part, and flanges on the floor part spaced apart from said flanges on the ceiling part, and including spring means at said flanges and between the ceiling and floor parts to allow the floor and ceiling parts and their flanges to move apart elastically.
Claim 2
Dependent Claim
111 words
In a corner protector, for the corner of an article having upper and lower parallel faces and adjacent edge faces, comprising floor and ceiling planar parts to slide over respective ones of said parallel faces and wall parts extending between the floor and ceiling parts to contact respective ones of said edge faces, the improvement in that the wall parts are defined by flanges on the ceiling part, and flanges on the floor part spaced apart from said flanges on the ceiling part, and including spring means at said flanges and between the ceiling and floor parts to allow the floor and ceiling parts and their flanges to move apart elastically.
Claim 3
Dependent Claim
38 words
A protector as claimed in claim 1 in which breakable fillets are provided between the flanges on the ceiling part and the flanges on the floor part whereby the wall parts are held temporarily at a fixed dimension.
Claim 4
Dependent Claim
110 words
A corner protector comprising a triangular-shaped ceiling part, a triangular-shaped floor part and side wall parts and edges of said parts defining a mouth for the protector, in which said protector is formed as a single moulding of plastics material, the moulding comprising two similar opposed spaced components one forming said ceiling part and one half of each of said wall parts and the other forming said floor part and the other half of each of said wall parts and springs of folded strand form extending between said components, adjacent to the mouth of the protector, lying in the plane of the wall parts and integral with said two components.
Claim 5
Dependent Claim
110 words
A corner protector comprising a triangular-shaped ceiling part, a triangular-shaped floor part and side wall parts and edges of said parts defining a mouth for the protector, in which said protector is formed as a single moulding of plastics material, the moulding comprising two similar opposed spaced components one forming said ceiling part and one half of each of said wall parts and the other forming said floor part and the other half of each of said wall parts and springs of folded strand form extending between said components, adjacent to the mouth of the protector, lying in the plane of the wall parts and integral with said two components.
Claim 6
Dependent Claim
100 words
A corner protector comprising a ceiling part, a floor part and side wall parts and edges of said parts defining a mouth for the protector, in which said protector is formed as a single molding of plastics material, the molding comprising two opposed spaced components, one forming said ceiling part and one fraction of each of said wall parts, and the other forming said floor part and the remaining fraction of each of said wall parts, and springs of folded strand form extending between said components, lying in the plane of the wall parts, and integral with said two components.
Claim 7
Dependent Claim
100 words
A corner protector comprising a ceiling part, a floor part and side wall parts and edges of said parts defining a mouth for the protector, in which said protector is formed as a single molding of plastics material, the molding comprising two opposed spaced components, one forming said ceiling part and one fraction of each of said wall parts, and the other forming said floor part and the remaining fraction of each of said wall parts, and springs of folded strand form extending between said components, lying in the plane of the wall parts, and integral with said two components.
