Abstract: This disclosure is directed to a key-activated, handle-operated three way (position) locking mechanism for removable automobile, or other vehicle, roof panels of the type wherein the handle customarily pivots from locked to open (unlocked) positions to permit removal of the roof "T-top" panels. The "T-top" lock-handle device of this invention comprises a latch stud adapter mechanism and locking cam mechanism each located substantially within a handle-housing and operative to permit locking and unlocking over a three position arc for the lock and a two position arc for the handle-housing and wherein unlocking is effected by meshing of notched surfaces on said adapter and locking cam whereby the locking cam drives the adapter upon rotation of the handle to unlock the "T-top" permitting its removal from the automobile roof.
