Lock assembly and a method for operating a lock mechanism

摘要

A barrel lock assembly 1 comprises a tubular housing 2 formed with a longitudinal access slot 4 extending through the wall of the housing 2; an inner barrel section 6 formed with an array of locking pins 8 extending upwardly from an array of slits 10; an electrically driven actuator 12 comprising a solenoid 14 and an actuating bar 16. In the assembled state (as shown in FIG. 2) the bar 16 is received by the access slot 4. The inner barrel 6 has extending from one end thereof a square peg section 18. A catch member 20 is fitted onto the square peg section 18. At the opposite end of the inner barrel there is a disc-like section 22 formed with a keyhole slot 24. Extending radially from the section 22 is a handle 26. The electrically driven actuator 12 is operated by sending an electrical signal to the solenoid 14 via a wire 27. When the solenoid 14 is activated the bar 16 is forced downwardly in a direction towards the locking pins 8. The bar 16 pushes the locking pins 8 radially inwardly away from the access slot 4.
