Disk-Access Storage Drive Retaining Device

       A device is described whereby a spring latch retainer and
holding frame provides the ability to secure a disk-access storage
drive (DASD) to a personal computer frame, without the need for
screws and fastening tools.  It also provides shock-absorbing action
and the assurance of meeting electrical grounding requirements.

      The spring latch retainer consists of a flat spring, as shown
in top view in Fig. 1 and side view in Fig. 2, which is formed
so that the same retainer can be used for both sides of the DASD
unit.  One end of the retainer is formed in a ninety-degree bend with
minimum radius.  The other end is a forward stop latch, also formed
in a ninety-degree bend, with a lead-in provided as an assembly aid.

      The DASD holding frame, as shown in Fig. 3, utilizes tabs
formed in the frame to hold the retainer in place when the retainer
is slid into the holding frame.  The tabs provide clearance for the
retainer to be mounted flush to the frame, except for the forward
stop. The retainer is moved forward into position where the entire
retainer is laying flat against the frame, as shown in Fig.  4.  If
required, the retainer can be spot welded in place to the frame.

      When a DASD unit is the inserted into the holding frame, its
mounting rails deflect the retention spring latches to the sides
until the DASD unit is fully seated in the frame past the forward
stop latch.  The retention sprin...
