Abstract
A locking mechanism for locking menbers, such as slidable or swingable closures, to another, usually stationary, member in closed position in which a bracket on the stationary member is engageable by a hook on the closure member to latch the members together while actuation of the hook into a position of disengagement from the bracket to unlock the members from each other is accomplished by a key operated push lock mechanism.
Claims10
In a lockable latch device;
- a lock body having a key plug rotatable and reciprocable therein, means for receiving a key in said plug at one end to unlock the plug for rotation between locked and unlocked position in the lock body, interengageable cooperating elements on said lock body and plug preventing axial movement of the plug toward the other end thereof in the lock body when in locked position including means forming a shoulder in said body and a lug on said plug which is disposed in opposed relation to said shoulder when the plug is in locked position, the end of said key plug facing the shoulder in said body being adapted to engage the shoulder when the key plug is in unlocked position and is pushed inwardly into the lock body thereby to limit the said inward movement of the key plug in the lock body, a latch lever having one end pivotally supported near said other end of the plug and extending across said other end of the plug to be engaged and pivoted thereby when the plug is moved axially in the direction of the said plug other end, said lever being mounted so that said one end is at one side of the lock body and a free end of the lever being disposed at the opposite side of the lock body, and a spring having one end connected to said lever and biasing said lever toward said other end of said plug, said body having an axial recess extending therein from the lever end of said body and registering with said lug in unlocked position of said plug.
