Abstract
Abstract The invention proposes a receptacle (20) for receiving and securing a stud (30) to enable a pair of members (32, 34) to be fastened together. The receptacle (20) is mounted in use in a non-circular aperture (38) in one of the members (34) and the stud (30) is mounted rotatably in the other member (32). The receptacle has a housing (22) for location in the aperture (38), the housing (22) being substantially U-shaped and comprising a base (40) and a pair of depending opposed substantially flat legs (42, 44). For engaging a front face (76) of the one member (34) an outwardly extending flange (46,48) is formed at the free end of each leg (42, 44). The sides (42', 44') of the legs (42, 44) prevent rotation of the receptacle (20) in the aperture (38). An element (28) is rotatable in the housing (22) between a first position in which it is biased against an inwardly directed tang (54) on each leg (42,44), and a second position in which it is biased against the rear face (78) of the one member (34) to lock the receptacle (20) on the one member (34). Means (24) are provided for securing the stud within the receptacle (20).

A receptacle (20) for receiving and securing a stud (30) to enable a pair of members (32, 34) to be fastened together, the receptacle (20) being mounted in a non-circular aperture (38) in one of the members (34) and comprising a housing (22) for location in the aperture (38), the housing (22) having a part for engaging a front face (76) of the one member (34) and means for preventing rotation of the receptacle (20) in the aperture (38), an element (28) rotatable in the housing.(22) between a first position in which it is biased against an abutment on the housing (22) and a second position in which it is biased against the rear face (78) of the one member (34) to lock the receptacle (20) on the one member (34), and means (24) for securing the stud within the receptacle (20); ; characterised in that the housing (22) is substantially U-shaped and comprises a base (40) and a pair of depending opposed substantially flat legs (42, 44), the part for engaging the front face of the member being formed by an outwardly extending flange (46, 48) at the free end of each leg (42, 44),the abutment being formed by an inwardly directed tang (54) on each leg (42, 44), and the means for preventing rotation of the receptacle (20) in the aperture (38) comprising the sides (42', 44') of the legs(42, 44).
Claim 2
Dependent Claim
233 words
A receptacle (20) for receiving and securing a stud (30) to enable a pair of members (32, 34) to be fastened together, the receptacle (20) being mounted in a non-circular aperture (38) in one of the members (34) and comprising a housing (22) for location in the aperture (38), the housing (22) having a part for engaging a front face (76) of the one member (34) and means for preventing rotation of the receptacle (20) in the aperture (38), an element (28) rotatable in the housing.(22) between a first position in which it is biased against an abutment on the housing (22) and a second position in which it is biased against the rear face (78) of the one member (34) to lock the receptacle (20) on the one member (34), and means (24) for securing the stud within the receptacle (20); ; characterised in that the housing (22) is substantially U-shaped and comprises a base (40) and a pair of depending opposed substantially flat legs (42, 44), the part for engaging the front face of the member being formed by an outwardly extending flange (46, 48) at the free end of each leg (42, 44),the abutment being formed by an inwardly directed tang (54) on each leg (42, 44), and the means for preventing rotation of the receptacle (20) in the aperture (38) comprising the sides (42', 44') of the legs(42, 44).
Claim 3
Dependent Claim
61 words
A receptacle according to claim 1, characterized in that the rotatable element (28) comprises a plate having one or more protrusions (72) extending from its edge, the protrusion or protrusions (72) being located within the housing when the plate (28) is in its first position, and extending outwardly from the housing (22) when the plate (28) is in its second position.
Claim 4
Dependent Claim
