19-Inch Rack Mount Kit for Standalone Devices

      A method and hardware for mounting small, normally standalone
machines such as tape drives in a 19-inch electronic cabinet or rack
is disclosed.

      Referring to Fig. 1, a sheet metal tray (1) is provided with a
metal strap (2) used to secure a standalone unit (such as a tape
drive) to the tray.  Snapping directly to the front of tray (1) is
cover (7) or (9) depending on the tape drive model (they are
different heights) with a suitable opening for drive access.  Covers
(7) and (9) are simple "make froms" from existing blank covers used
to cover unused device slots in the rack.  A hole for access to the
device is cut in each cover.  Snapped to the cover is appearance
bezel (8) or (10)--again depending on the tape drive model--which is
used to provide both an "integrated" system appearance and cover the
tape drive power switch.  Note that devices that are rack mounted in
most systems are generally controlled by the rack power and it is not
desirable to allow inadvertent access to a device power switch.  The
switch can be gotten to if necessary by snapping cover (7) or (9)
off--a simple operation.  A mounted drive is shown as Fig. 1A.

      A single design for tray (1) and strap (2) accommodates two
sizes of tape drive, which vary in height, by providing multiple
attachment locations for the strap.  Additional attachment points
will permit other height drives to be mounted.  This is shown in Fig.
2.  Access to  the strap fastening system is improved by providing a
"twist-key" approach to the attachment of the right side of the strap
as shown in the Figure.  This cuts the number of fasteners for the
strap--and thus the drive--to one and eliminates the need to tighten
a screw on the right side of the unit, which has limited space
available.  The tray is equipped with integral formed stops which
properly locate the drives in a side to side direction with the
appearance bezels; in the front to back direction, drives must be
adjusted to the bezels (a simple operation) as there is both
substantial tolerance in drive length and a nominal difference in the
length of the two drives themselves.

      As shown in Fig. 3, the tray is simply mounted in any 19-inch
rack with standard Electronics Industries Association (EIA) mounting
holes; tabs that are integrally formed from the tray at the front and
back provide the proper location for the unit in the rack and solid
pins at the front provide the necessary rigidity.  As shown in Fig.
4, the unit is fastened with two screws at the rear (which both
secure the unit and provide rigidity to that end of the tray).

Other attributes of the design are:
  1.  The ability, with only minor changes (and no change to the
       concept) to tailor the mounting system to other sizes and
       (i.e., optical) of drives.  This is accomplished merely by...
