ABSTRACT:
The tape measure includes a lock for locking the tape in an extended position from its case. The lock includes a toggle pivotably mounted on the case and a lock shoe extending from one end of the toggle to a position adjacent the tape. The case includes guides, such that when the toggle is depressed, the lock shoe is forced against the tape so as to wedge the tape between the lock shoe and the case to prevent its retraction.
