Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
173 words
A pencil caddy, comprising an elongated hollow body having top, bottom and side walls, said side walls being hinged at their upper and lower edges to the top and bottom walls, and hinged intermediate their top and bottom edges parallel to the hinges at the top and bottom edges, said body having open ends the edges of which are defined by the end edges of the top, bottom and side walls and said edges of the side walls at each end sloping from the edges of the top and bottom walls inwardly and meeting at the hinge line intermediate the side walls, such that the end openings are re-entrant and end members hinged at the opposite ends to the end edges of the top and bottom walls and corresponding in length to the lengths of the end edges of the side wall, said end members being adapted to be sprung into the re-entrant openings to hold the body distended and to be withdrawn from the openings to permit the body to be flattened.
Claim 2
Dependent Claim
173 words
A pencil caddy, comprising an elongated hollow body having top, bottom and side walls, said side walls being hinged at their upper and lower edges to the top and bottom walls, and hinged intermediate their top and bottom edges parallel to the hinges at the top and bottom edges, said body having open ends the edges of which are defined by the end edges of the top, bottom and side walls and said edges of the side walls at each end sloping from the edges of the top and bottom walls inwardly and meeting at the hinge line intermediate the side walls, such that the end openings are re-entrant and end members hinged at the opposite ends to the end edges of the top and bottom walls and corresponding in length to the lengths of the end edges of the side wall, said end members being adapted to be sprung into the re-entrant openings to hold the body distended and to be withdrawn from the openings to permit the body to be flattened.
Claim 3
Dependent Claim
40 words
A structure according to claim 1, comprising parts extending laterally from the end members and in the plane thereof and symmetrically with respect to the axis of the body, comprising laterally spaced supports for supporting the body in stable equilibrium.
Claim 4
Dependent Claim
22 words
A structure according to claim 1, wherein the body has in the top wall openings for receiving articles for upright support therein.
Claim 5
Dependent Claim
152 words
A pencil caddy, comprising an elongated hollow body having four quadrilaterally arranged side walls hinged longitudinally to each other and two of the opposed side walls being hinged intermediate their edges parallel to the hinges connecting the side walls, so as to be flattened in a plane containing said intermediate hinges, said body having open ends defined by the end edges of the four side walls, the end edges of the side walls hinged intermediate their edges sloping inwardly toward the intermediate hinges so that the end openings are re-entrant and flexible end members hinged at their opposite ends to the end edges of the other two side walls and corresponding in length to the length of the end edges of the side walls intermediate their ends, said end members being adapted when pressed into the recessed openings to hold the body distended and when withdrawn to permit the body to collapse.
