    Abstract: 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.

  • Patent number: 4053177
    Abstract: An adjustable, flush mounted, over-center hook latch of the type employed to secure aircraft panels. The effective length of the latch arm is adjustable to correct misalignment of the components joined by the latch by moving the pivot axis of the latch arm relative to the fulcrum axis of the latch handle. This is accomplished by a pair of cooperating yoke members, one of which is mounted about the pivot axis and the other about the fulcrum axis and are slidable relative to each other by a driver. By the particular arrangement of the parts, the latch can be adjusted when installed and in its closed position by the driver being engaged with a conventional drive tool extending through a small opening in the latch handle.
