Abstract
A thin lock has a housing, a core assembly mounted in the housing, multiple pin assemblies arranged longitudinally in the core assembly, and a latch assembly mounted through the housing and selectively activates the core assembly and the pin assemblies. Thus, when the thin lock is mounted on a door panel, numbers of the pin assemblies does not relate to a thickness of the door panel. Therefore, the numbers of the pin assemblies are able to be added to increase the complexity and enhance the safety of the thin lock according to user's need.

A thin lock comprising
- a housing having
- a front half-housing having
- a core recess formed in a rear surface of the front half-housing;
- a latch hole formed through the front half-housing;
- an inner wall defined between the core recess and the latch hole;
- a through hole formed through the inner wall of the front half-housing;
- and
- a keyhole formed through a front surface of the front half-housing and corresponding to and communicating with the core recess;
- and
- a rear half-housing attached to the rear surface of the front half-housing, corresponding to the core recess and having
- an inner surface corresponding to the core recess of the front half-housing;
- and
- at least one first pin mount formed longitudinally on the inner surface of the rear half-housing and disposed beside a sliding recess, each of the at least one first pin mount having multiple first pin recesses formed separately in the at least one first pin mount and arranged longitudinally along the at least one first pin mount;
- a latch assembly mounted through the latch hole of the front half-housing and having a driving shaft mounted rotatably through the latch hole of the front half-housing and having at least one lock recess formed in a peripheral surface of the driving shaft and corresponding to the through hole of the front half-housing;
- a core assembly mounted slidably in the core recess of the front half-housing and having
- a middle pin mount corresponding to the at least one first pin mount of the rear half-housing and having
- a key recess formed longitudinally in a front surface of the middle pin mount;
- and
- multiple first pin holes formed through the middle pin mount and respectively aligning with the first pin recesses of the at least one first pin mount;
- and
- a lock protrusion protrudes down from a lower edge of the core assembly, mounted through the through hole of the front half-housing, abutting the driving shaft of the latch assembly and selectively engaging the at least one lock recess of the driving shaft;
- and
- multiple first pin assemblies mounted respectively in the first pin recesses of the rear half-housing and the first pin holes of the core assembly, each first pin assembly having
- a first outer pin mounted in the first pin hole of the core assembly;
- a first inner pin mounted in the first pin recess of the rear half-housing;
- and
- a first resilient element mounted in the first pin recess of the rear half-housing and having two ends respectively abutting the at least one first pin mount and the first inner pin.
