Abstract

Disclosed is a single molded part for side handles on a small to medium-sized data processing system. The desired appearance is an asymmetric individual left and right handle. As a result of unique symmetry, this appearance is achieved with a single reversible part, thus eliminating the need for double tooling.

Symmetrical - Asymmetric Handle

      Disclosed is a single molded part for side handles on a small
to medium-sized data processing system.  The desired appearance is an
asymmetric individual left and right handle.  As a result of unique
symmetry, this appearance is achieved with a single reversible part,
thus eliminating the need for double tooling.

      As shown in Fig. 1, this is accomplished by a "Z" cross section
being the major component of the part.

      As shown in Fig. 2, on the back of the part, end 1 is open and
end 2 closed.  On the front of the part, end 1 is closed and end 2 is
open.  The part is mirrored end for end and side to side at the same
time.

      As shown in Fig. 3, by rotating the part on a horizontal axis,
the same geometry is transferred to the opposite side of the part.
This gives the desired unique asymmetric appearance of individual
left and right parts.

      Because the part is reversible, both sides of the part must
have a decorative finish, free of any gate and ejector pin marks.

      As shown in Fig. 2, a flange 4 on the vertical center plane of
the part provides a surface, outside the perimeter of the part, on
which to gate and eject the part.  Besides providing an ejection
surface, this flange is used as a mounting feature for attaching the
handle to the parent cover.  It also helps in the molding process and
adds strength to the part.
