Abstract
Abstract The invention relates to fasteners for two parts of a body which are wholly contained within the body and not visible when the two parts are joined. The fastener comprises a resilient member secured inside the first part of the body projecting internally of the body and an orifice formed inside the second part of the body. The resilient member is shaped to enter the orifice and verge the two parts together and to permit separation of the two parts by a relative pivoting movement adjacent to the abutting joint between the parts whereby the resilient member is retracted from the orifice.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
253 words
A fastener for a first and a second part of a hollow body, each of said parts having an edge about which said parts are relatively pivotable, said edges abutting when said first and second parts are secured together and forming a coplanar surface of said first and second parts, said fastener comprising a resilient elongate strip including a substantially U-shaped strip having two legs and a U-shaped portion, one of the legs being straight and secured internally of said first part adjacent to said edge thereof, said U-shaped portion extending into said second part and adjacent to an edge thereof, said elongate strip further including a substantially V-shaped portion formed therein, said V-shaped portion projecting inwardly of and contained in said first part, a member attached internally of said second part spaced from said edge thereof and an orifice formed in said member so as to be contained within said first part, said orifice being shaped to receive said V-shaped portion of said elongate strip to locate said elongate strip, said V-shaped portion entering into said orifice when said edges are abutted and said first part is pivoted about said abutting edges towards said second part and said V-shaped portion retracting from said orifice when said edges are abutted and said first part is pivoted about said abutting edges away from said second part, said resilient elongate strip urging said first and second parts together when said V-shaped portion enters said orifice and said first part is pivoted towards said second part.
Claim 2
Dependent Claim
253 words
A fastener for a first and a second part of a hollow body, each of said parts having an edge about which said parts are relatively pivotable, said edges abutting when said first and second parts are secured together and forming a coplanar surface of said first and second parts, said fastener comprising a resilient elongate strip including a substantially U-shaped strip having two legs and a U-shaped portion, one of the legs being straight and secured internally of said first part adjacent to said edge thereof, said U-shaped portion extending into said second part and adjacent to an edge thereof, said elongate strip further including a substantially V-shaped portion formed therein, said V-shaped portion projecting inwardly of and contained in said first part, a member attached internally of said second part spaced from said edge thereof and an orifice formed in said member so as to be contained within said first part, said orifice being shaped to receive said V-shaped portion of said elongate strip to locate said elongate strip, said V-shaped portion entering into said orifice when said edges are abutted and said first part is pivoted about said abutting edges towards said second part and said V-shaped portion retracting from said orifice when said edges are abutted and said first part is pivoted about said abutting edges away from said second part, said resilient elongate strip urging said first and second parts together when said V-shaped portion enters said orifice and said first part is pivoted towards said second part.
Claim 3
