Abstract
Abstract For use in the formation of a lock a continuous one-piece moulding in plastics material which comprises a first portion and two further portions contiguous with the first portion at a pair of hinge strips, the first portion defining a channel into which one of the further portions can be swung and the other further portion being swingable against the first portion to close the channel thereby to form a hollow lock body and to restrict swinging movement of said one further portion which latter portion is formed to then serve as a lock bolt head movable between a position in which it extends from an end of the hollow lock body and a retracted position in which it is swung inwardly of the body.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
125 words
For use in the formation of a lock, a continuous one-piece moulding in plastics material which comprises a first portion and two further portions contiguous with the first portion at a pair of hinge strips, the first portion defining a channel into which one of the further portions can be swung and the other further portion being swingable against the first portion to close the channel thereby to form a hollow lock body and to restrict swinging movement of said one further portion which latter portion is formed to then serve as a lock bolt head movable between a position in which it extends from an end of the hollow lock body and a retracted position in which it is swung inwardly of the body.
Claim 2
Dependent Claim
125 words
For use in the formation of a lock, a continuous one-piece moulding in plastics material which comprises a first portion and two further portions contiguous with the first portion at a pair of hinge strips, the first portion defining a channel into which one of the further portions can be swung and the other further portion being swingable against the first portion to close the channel thereby to form a hollow lock body and to restrict swinging movement of said one further portion which latter portion is formed to then serve as a lock bolt head movable between a position in which it extends from an end of the hollow lock body and a retracted position in which it is swung inwardly of the body.
Claim 3
Dependent Claim
25 words
A moulding as claimed in claim 1, wherein said further portions are disposed at the opposite ends of the channel defined by the first portion.
Claim 4
Dependent Claim
42 words
A moulding as claimed in claim 2, wherein the channel in the first portion is open at the end to which the bolt head portion is disposed and closed at its other end by an end wall part of the first portion.
Claim 5
Dependent Claim
43 words
A moulding as claimed in claim 2 wherein the first portion has a pair of flanges projecting laterally outwardly froM the mouth of the channel which flanges are perforated by apertures to receive mounting screws for mounting the lock body to a door.
Claim 6
Dependent Claim
17 words
A moulding as claimed in claim 1, wherein said other further portion is generally of plate formation.
Claim 7
Dependent Claim
105 words
A moulding as claimed in claim 2 wherein the first portion has a pair of flanges projecting laterally outwardly from the mouth of the channel which flanges are perforated by apertures to receive mounting screws for mounting the lock body to a door, and wherein said other further portion is generally of plate formation, and wherein the outer periphery of said other further portion is shaped to match the outer peripheries of said flanges when that portion is swung against the first portion to close the channel and is also provided with a pair of apertures to then align with the apertures in the flanges.
Claim 8
Dependent Claim
63 words
A moulding as claimed in claim 1, wherein said one further portion includes an actuation plate part which will project inwardly of the lock body when the one further portion is swung into position to serve as a bolt head and said other further portion has a central aperture through which an actuator plunger can be extended to engage that actuation plate part.
Claim 9
Dependent Claim
32 words
A moulding as claimed in claim 7, wherein the restriction of swinging movement of said one further portion is caused by engagement of the actuation plate part with said other further portion.
