Device for Preventing Unauthorized Removal of Individual Logic Books
From a Logic Cage

      An advent of easily removable "book"-style logic packages
from the typical logic cage has created a need to protect the
customer from loss of confidential or otherwise "secure" data and/or
physical assets through unauthorized removal or theft of those book
packages.

      Presented here is a non-complicated, low-cost device which,
when installed on a logic book, strongly resists unauthorized book
removal with a lockout system.  If the system is forced, evidence of
entry is apparent.

      Shown in Fig. 1 is a logic book 1 being installed in logic cage
2.  Book 1 is equipped with latches 3 that engage forms 4 in cage 2,
as shown in the cut-away inset to the figure.

      Referring to Fig. 2, latch 3 is molded with slot 5 through
which pivoting link 6 protrudes; link 6 is, in turn, installed on
book cover stiffening post 7, on which it is free to turn.  Link 6 is
metallic in nature for strength, but may be made of other materials
if the application warrants.  Link 6 is equipped with the following
features: hole 8 whose edge is tangent to the surface of latch 3 when
latch 3 is in the closed position and through which the hasp (whose
diameter is slightly smaller than that of hole 8) of a
customer-supplied padlock 10 may be passed, and wings 9 designed to
cam link 6 via contact with the ends of latch 3 slot 5, thus
self-positioning, eliminating binding, and ensurin...
