Embodiment Construction

[0015] Referring to the drawings, there is shown a lock device 1 for mounting on a closure (not shown) having inner and outer sides, the lock device 1 comprising a cylinder or body 2 which defines a cylindrical bore 3 and has (in use) spaced apart inner and outer cylindrical portions 4, 5 between which are mounted a rotatable cam 6 and a stop member 7a, the cam 6 has a hole 7 aligned with the cylindrical hole 3 and is operable to operate the locking mechanism (not shown) of the closure via the drive portion 6a associated with the cam 6 and the inner cylindrical portion thereby Try to avoid the operation of the locking device when the device is maliciously damaged.

[0016] The lock device 1 shown in the accompanying drawings is known as a Euro cylinder lock, which has a bulbous body or cylinder and can be mounted on doors such as uPVC doors, double aluminum glass doors and / or composite doors. Closures for material doors or wooden doors, etc. The locking mechanism is operated...

Abstract

The invention relates to a lock apparatus for mounting on a closure having internal and external faces, comprising a body (2) defining a cylindrical bore (3) and having internal and external (in use) spaced cylinder parts (4,5) mounting therebetween a rotatable cam (6) having a bore (7) aligned with the cylindrical bore (3) and adapted for operating a locking mechanism of a closure, characterised by stop means (7a) associated with the cam (6) and the internal cylinder part (4) whereby to obviate operation of the lock apparatus (1) when the lock apparatus is vandalised.

Description

technical field [0001] The present invention relates to a lock and in particular to a lock for mounting to a closure and for operating a locking mechanism of the closure. Such locks are often known as Euro Cylinder or Europrofile cylinder locks. Background technique [0002] This type of European cylinder lock usually has a cylindrical part in which a rotatable cylinder (barrel) is installed, and the cylindrical part can be turned to open, unlock, close, locked position and Rotate from open, unlocked, closed, locked positions, the key operates the key pin to move a spring-loaded driver pin (driver pin) to the shear line defining the boundary between the cylinder and the barrel so that The cylinder is turned by turning the key. There is also a cam that is fixed to the cylinder and has the part that operates the locking mechanism of the closure. As the barrel rotates, the cam also rotates so that the cam portion operates the locking mechanism. However, Euro style cylinder ...
