Title:
LOCK MECHANISM
Document Type and Number:
Japanese Patent JPS54117298
Kind Code:
A
Abstract:
There is disclosed a lock mechanism that has been designed to take up a minimum amount of space and thus be accommodatable in a relatively shallow structure. Said lock mechanism includes a pivotally mounted latch bolt, a deadlock member associated with said latch bolt, with biasing means urging said deadlock member to a locking position. To control the operation of the deadlock member there is provided a deadlock trigger and a deadlock position lever providing an operational connection between said trigger and the deadlock member. A primary operating lever as provided comprised of a first pivotally mounted arm portion and a second arm portion integral therewith and connected with the latch bolt by a loss motion connection. The pivot axis for said latch bolt, said primary operating lever and said deadlock member are disposed parallel to and adjacent the front plate of the casing structure, thereby enabling the lock mechanism to be accommodated and to function within a shallow casing structure.
