Abstract

Abstract A lock, particularly a padlock, with tumbler pins controlled by magnets disposed on the key side and suspended on their middle section for a pendulum movement, which comprises a plurality of tumbler pins and a locking plate, whereby the tumbler pins are directed with one end towards the locking plate. The latter has an opening for entrance of the ends of the correspondingly aligned tumbler pins, and is mounted for parallel displacement perpendicularly to its plane and retained by a spring load in an abutment position in front of the ends of the tumbler pins.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 210 words
A lock, particularly a padlock, with magnetically operative tumbler pins disposed on a key side and suspended on their middle section for a pendulum movement, comprising a plurality of tumbler pins, a locking plate, said tumbler pins being directed with first ends, respectively, towards said locking plate, said locking plate having openings for entrance of said first ends, respectively, of the correspondingly aligned tumbler pins, and said locking plate defining a plane and being mounted transversely shiftable relative to said plan, said locking plate being retained in an abutment position in front of said one end of said tumbler pins, a U-shackle, spring means biasing said U-shackle in a closing direction, a baffle lever having two arms, one of said arms abutting said U-shackle, said locking plate having a locking wing, the latter having a rearward end, the other arm of said baffle lever being coupled with said locking wing of said locking plate, said rearward end of said locking wing adapted to engage boltingly in said U-shackle, a spring operatively biasing said locking plate in the direction of said tumbler pins being coordInated to said baffle lever, and said spring having a lesser operative force than that of said spring means which biases said U-shackle in an opposite direction.
Claim 2
Dependent Claim 210 words
A lock, particularly a padlock, with magnetically operative tumbler pins disposed on a key side and suspended on their middle section for a pendulum movement, comprising a plurality of tumbler pins, a locking plate, said tumbler pins being directed with first ends, respectively, towards said locking plate, said locking plate having openings for entrance of said first ends, respectively, of the correspondingly aligned tumbler pins, and said locking plate defining a plane and being mounted transversely shiftable relative to said plan, said locking plate being retained in an abutment position in front of said one end of said tumbler pins, a U-shackle, spring means biasing said U-shackle in a closing direction, a baffle lever having two arms, one of said arms abutting said U-shackle, said locking plate having a locking wing, the latter having a rearward end, the other arm of said baffle lever being coupled with said locking wing of said locking plate, said rearward end of said locking wing adapted to engage boltingly in said U-shackle, a spring operatively biasing said locking plate in the direction of said tumbler pins being coordInated to said baffle lever, and said spring having a lesser operative force than that of said spring means which biases said U-shackle in an opposite direction.
Claim 3
Dependent Claim 23 words
The lock, as set forth in claim 1, wherein said baffle lever is abutted by one end of said U-shackle of said lock.
Claim 4
Dependent Claim 102 words
The lock, as set forth in claim 1, wherein said locking plate has on its wide side pointing towards said tumbler pins a guiding pin and opposite to the latter said locking wing, the latter is operatively coupled with said other arm of said baffle lever, said one arm of said baffle lever is disposed below an end-face of said U-shackle, which has a ring shoulder, said spring means supporting itself on said ring shoulder and the latter has a radially directed projection, and an entrance opening disposed opposite said projection, upon aligning said U-shackle to a correct angular position for closing.
Claim 5
Dependent Claim 32 words
The lock, as set forth in claim 1, wherein said locking plate has multi-edged insert pieces with equal edge lengths and said insert pieces define openings for entrance of said tumbler pins.
