Dual Size Card Guide for Personal Computers

       Described is a hardware implementation that provides a
guide and retaining mechanism for two sizes of circuit cards as used
in personal computers (PCs).

      In prior art, different models of PCs required special circuit
card retaining brackets in addition to card guides to prevent
loosening during shipping.  The concept described herein provides a
mechanism that both guides and retains two different sizes of circuit
cards, thereby eliminating special retainers.  The guides have
incorporated in them latch/ snap retainers that hold the cards after
they are installed.

      Fig. 1 is an isometric view of the card guides with one guide
holding a typical circuit card.  The dotted line illustrates the
typical width of the smaller of the two card types.  Circuit card 10
is shown positioned in one of the dual card guides 11.  Fig. 2 is an
exploded isometric view of circuit card 10 positioned in one side of
the guide 11.  Side retainer 12 and edge retainer 13 are designed to
deflect slightly during installation of circuit card 10.  When
circuit card 10 is fully inserted, both side retainer 12 and edge
retainer 13 snap into place against circuit card 10 so as to prevent
unlatching.
