Abstract
Abstract A gun lock has two relatively movable and lockable hooked jaws for restraining movement of components of a gun that must be relatively moved for its operation (e.g. trigger and guard, or grip and stock of a pump action shotgun). The jaws project rearwardly from a body housing a cam rotatable via a key to displace one jaw away from the other.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
136 words
A lock for a gun comprising: a body having a rear face; first and second elongate jaw means mounted to said body and extending rearwardly of said rear face, said first and second jaw means having oppositely directed hook formations; pivot means pivotally mounting said first jaw means to said body so that it is pivotable towards and away from said second jaw means; cam means displaceably mounted to said body adjacent said first jaw means, said cam means having a cam surface and said first jaw means having follower means for cooperating with said cam surface, said cam surface being shaped so that displacement of the cam means in one sense urges said first jaw means to pivot away from said second jaw means; and security actuator means for actuating displacement of said cam means.
Claim 2
Dependent Claim

A lock for a gun comprising: a body having a rear face; first and second elongate jaw means mounted to said body and extending rearwardly of said rear face, said first and second jaw means having oppositely directed hook formations; pivot means pivotally mounting said first jaw means to said body so that it is pivotable towards and away from said second jaw means; cam means displaceably mounted to said body adjacent said first jaw means, said cam means having a cam surface and said first jaw means having follower means for cooperating with said cam surface, said cam surface being shaped so that displacement of the cam means in one sense urges said first jaw means to pivot away from said second jaw means; and security actuator means for actuating displacement of said cam means.
Claim 3
Dependent Claim
23 words
A lock for a gun according to claim 1 wherein said cam is rotatably mounted and said cam surface is spiral in form.
Claim 4
Dependent Claim
108 words
A lock for a gun according to claim 2 wherein said security actuation means are key operable means adapted to accept a key only in a predetermined orientation, and comprise an element which is rotatable by means of a key and is coupled to said cam means via a lost motion coupling such that after rotation of said key, element and cam to effect pivoting of said first jaw means away from said second jaw means to a desired extent, said key is rotatable back to the predetermined orientation in which it is removable with conomitant rotation of said element while the cam remains in its rotated configuration.
