Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
173 words
In a magnetic lock having an actuating member movable between a locking position and an unlocking position, the combination of: at least one cylindrical barrel member having one end closed, a pistonlike member axially slidable within said barrel member and defining therewith a shallow ball chamber of substantially cylindrical shape, a magnetizable ball having a diameter slightly less than the depth of the ball chamber and freely movable in said ball chamber while blocking axial sliding of said pistonlike member within said barrel member, a ball receiving recess provided in one of the surfaces delimiting said ball chamber for snugly accommodating at least a portion of said ball therein, an additament opposing movement of said ball into a position aligned with said recess and means coupling one of said barrel members and pistonlike member to said actuating member, whereby when said ball is aligned with said recess said pistonlike member is freed to penetrate into said barrel member and said actuating member is conditioned to move from said locking to said unlocking position.
Claim 2
Dependent Claim
173 words
In a magnetic lock having an actuating member movable between a locking position and an unlocking position, the combination of: at least one cylindrical barrel member having one end closed, a pistonlike member axially slidable within said barrel member and defining therewith a shallow ball chamber of substantially cylindrical shape, a magnetizable ball having a diameter slightly less than the depth of the ball chamber and freely movable in said ball chamber while blocking axial sliding of said pistonlike member within said barrel member, a ball receiving recess provided in one of the surfaces delimiting said ball chamber for snugly accommodating at least a portion of said ball therein, an additament opposing movement of said ball into a position aligned with said recess and means coupling one of said barrel members and pistonlike member to said actuating member, whereby when said ball is aligned with said recess said pistonlike member is freed to penetrate into said barrel member and said actuating member is conditioned to move from said locking to said unlocking position.
Claim 3
Dependent Claim
26 words
In a lock according to claim 1, means for attaching said pistonlike member in any one of a plurality of angular positions to said actuating member.
Claim 4
Dependent Claim
30 words
In a lock according to claim 1, a closing member in said recess resiliently retained in closing position and retractable from said position in response to pressure from said ball.
Claim 5
Dependent Claim
19 words
In a lock according to claim 1, said recess being provided in the end surface of said pistonlike member.
Claim 6
Dependent Claim
20 words
In a lock according to claim 1, said recess being provided in one of the surfaces of said barrel member.
Claim 7
Dependent Claim
38 words
In a lock according to claim 1, a plurality of ball chambers having their pistonlike members provided with recesses on the end sUrfaces thereof and of ball chambers provided with recesses in the surfaces of said barrel members.
Claim 8
Dependent Claim
34 words
In a lock according to claim 1, a plurality of ball chambers having the recesses thereof at different distances from the axis of the chamber and in different angular positions relative to said axis.
Claim 9
Dependent Claim
29 words
In a lock according to claim 1, a magnet in a surface portion of said ball chamber spaced from said recess and defining a locking position of said ball.
Claim 10
Dependent Claim
31 words
In a lock according to claim 1, a plurality of ball chambers adjacent to each other and having magnetic balls therein providing a predetermined position through magnetic attraction between said balls.
