Motion Stop for a DASD Device

       Described is a device for stopping the motion of a DASD
unit as it is installed within a bay of a system unit and for holding
the DASD unit in place thereafter.

      As shown in the figure, a floor 10 of a bay, provided in a
system unit for the installation of a DASD unit, includes a pair of
rail surfaces 12 for the sliding installation of such a unit in the
direction of arrow 14.  A stop device 16 is snapped into place to
provide a surface 18 limiting the motion of the DASD device in the
direction of installation.

      Stop device 16 is installed within a T-shaped aperture 20
extending through floor 10 from a stepped surface 21 between a raised
surface 22 and a depressed surface 23.  (In the figure, a portion of
surface 22 adjacent to aperture 20 is cut away to reveal details of
stop device 16).  Device 16 includes a pair of flexible latches 24,
operating through openings 26 in surface 21, being forced inward to
snap back outward as device 16 is installed in the direction of arrow
14.  A raised transverse rib 28, lying adjacent to corners 30 of
aperture 20, prevents motion of device 16 in the direction of arrow
14 after installation, while a central rib 32 provides stiffness for
part 16.

      When a DASD unit is installed in the bay, a lower surface of
the DASD unit contacts transverse rib 28, causing a frictional force
which slows the motion of the DASD unit.  Further motion of the DASD
unit brings its end t...
