Thisjnvention relates generally to the art of
-locks and latches, and more particularly to locks
of the type embodying a handle movable from
an operating position wherein it is accessible
for manipulation to open the closure with which
it is associated, to a non-operating position
wherein'the handle may be substantially flush
with theV exterior surface of the closure.
An'V object of this invention is to provide a lock
of the above described character, which, in as
sociation with the door of an automobile, for
example, is automatically operable in response
to closing of the door,ìto move the outside door
handle from its operating position wherein it
projects from the door for manipulation, to a
non-operating position wherein the handle will
be substantially flush with the exterior surface
of the door, thus adding to the safety and se
curity of the vehicle by preventing unauthorized
persons from tampering with the handle and pos
sibly breaking off same in an effort to force the
lock; adding to the safety of operation of the
vehicle by eliminating dangerous projecting
handles which have been the cause of many ac
cidents; and enhancing the streamlined appear~
ance of the vehicle.
