초록 ▼

A flush-mountable, key-controlled, handle-operated door lock is provided with an automatic self-locking linkage for permitting the handle to move once, but only once, out of a nested position after a key control has been operated to “cock”the linkage. Once the linkage has been cocked, the handle can be moved one time out of and returned to its nested position, whereafter the linkage operates to retain the handle in its nested position until the key control is again operated to cock the linkage. The automatic latching linkage includes a housing assembly, a pair of cams, and a pair of springs. A feature of the automatic latching linkage is that its several components can be assembled easily on an existing, in-service lock to provide the existing lock with a one-trip automatic locking capability. The latching linkage components are assembled by installing the components one at a time in an essentially stacked arrangement, one atop the other. The simple assembly steps required can be carried out even where accessibility to the rearward face of an in-service lock is quite limited.

In a self-locking mechanism for a lock of the type having a bolt retractable by handle operation to an unlatching position, a handle movable with the bolt between latching and unlatching positions, and means for selectively permitting and preventing handle movement to retract the bolt, the improvement comprising: (a) a movable actuating member having an abutment surface and being movable with operation of the handle and the bolt in an unlatching direction; (b) a first operating means being movable between a locked position engaging the abutment surface of the actuating member to prevent its movement in the unlatching direction, and an unlocked position out of engagement with the abutment surface wherein the first operating means permits movement of the actuating member in the unlatching direction; (c) first independent spring means urging the first operating means toward its locked position; (d) a second operating means interengageable with the first operating means when the first operating means is in its unlocked position for releasably retaining the first operating means in its unlocked position; (e) second independent spring means for urging the second operating means into interengagement with the first operating means when the first operating means is in its unlocked position; and, (f) the second operating means having a striker surface formed thereon for engagement by the abutment surface as the handle is moved to its operating position to move the second operating means sufficiently to release interengagement between the first and second operating means and to thereby free the first operating means to return to its locked position under the influence of the first spring means.
