Appeal No. 96-1416
Application 08/118,066
an externally threaded insert member having a polygonal-shaped internal
channel extending therethrough;
an insert mounting bracket including a base plate secured in combination with
the inner surface of the access panel and a cylindrical housing, said insert member
being inserted in combination with the mounting bracket so that said insert member is
restrained by said cylindrical housing and is rotatable with respect thereto and the
internal surface of the access panel and said polygonal-shaped internal channel is
aligned with the minimal access aperture of the access panel;
a captured floating nut having an internal cylindrical configuration, a first portion
of said internal cylindrical configuration having threads and a second portion thereof
having a smooth surface;
means for mounting said captured floating nut in nonrotatable combination with
the inner surface of the frame;
a safety lock member having a polygonal-shaped body member disposed within
said captured floating nut and operative for axial displacement with respect to said
smooth surface of said second internal portion thereof, said polygonal shape of said
body member being complementary to said polygonal shape of said internal channel;
and
a removable key member having a polygonal-shaped shank sized for insertion
through the minimal access aperture of the access panel, said polygonal shape of said
shank being complementary to said polygonal shape of said internal channel;
said low profile latch mechanism being engaged and locked to close the access
panel by inserting said polygonal-shaped shank of said removable key member through
the minimal access aperture to engage said polygonal-shaped internal channel,
rotating said removable key member to thread said insert member into said captured
floating nut while concomitantly axially displacing said safety lock member away from
said insert member, and removing said removable key member upon full engagement
of said insert member within said captured floating nut wherein said safety key member
is axially displaced into mechanical engagement with said polygonal-shaped internal
channel of said insert member to lock said low profile latch mechanism;
