Abstract

PROBLEM TO BE SOLVED: To solve the problem that complexity and safety are deteriorated.SOLUTION: A low-profile lock includes: a housing; a core assembly which is mounted in the housing; a large number of pin assemblies which are longitudinally disposed in the core assembly; and a latch assembly which is mounted through the housing to selectively actuate the core assembly and the pin assemblies. When the low-profile lock is mounted in a door panel, the number of the pin assemblies is not associated with the thickness of the door panel. Thus, the number of the pin assemblies can be additionally increased to improve safety by increasing the complexity of the low-profile lock according to a user's need.

Description

  The present invention relates to a thin lock, and more particularly to a thin lock suitable for a thin door.

  A conventional pin tumbler lock has an outer lock core, an inner lock core, and a composite pin assembly. The outer lock core is tubular and has a number of pin recesses formed radially on the inner surface of the outer lock core and arranged axially along the outer lock core. The inner lock core is disposed in the outer lock core, and has a key hole formed in the axial direction at one end portion of the inner lock core, and is formed in a radial direction across the inner lock core and in the axial direction along the inner lock core. A plurality of pin holes arranged and aligned with the pin recesses of the outer lock core. The pin assemblies are respectively disposed in the corresponding pin recesses of the outer lock core and the pin holes of the inner lock core. Each pin assembly has two pins of different lengths. By inserting the key into the key hole of the inner lock core and pressing the pin, the contact surface of the corresponding pin and the contact surface of the outer lock core and the inner lock core are flush with each other. The tumbler lock opens. In the conventional pin tumbler lock, as the number of pin assemblies increases, the complexity increases, the safety is improved, and unauthorized unlocking can be prevented.

  When a conventional pin tumbler lock is mounted on a door panel, the pin tumbler lock is disposed across the inner surface and the outer surface of the door panel. When the door panel is thin, the lengths of the outer lock core and the inner lock core are shortened, and the number of pin assemblies is accordingly reduced. Therefore, the complexity and safety of the conventional pin tumbler lock are reduced.

  The main object of the present invention is to provide a thin lock. The thin lock includes a housing, a core assembly mounted on the housing, a number of pin assemblies arranged in the longitudinal direction in the core assembly, a core assembly and a pin assembly mounted through the housing, And a latch assembly for selectively actuating.

  When this thin lock is mounted on a door panel, the number of pin assemblies is not related to the thickness of the door panel. For this reason, the number of pin assemblies can be added to increase the complexity of the thin lock and improve safety as required by the user.
