Non-Obstructing Lens Mount for Light-Emitting Diode Indicators

       Described is a lens assembly design for use in a computer
system which transmits light from a light-emitting diode (LED)
indicator mounted behind the cover through an aperture in the cover
to disperse light outside of the cover.

      In prior art, a typical lens mount required mechanical latch
elements on the cover or involved heat staking or adhesives to hold
the lens in place.    The approach made replacement of defective
lenses difficult and often caused damage to the cover.  Also, the
lens was often held in place with a hook or a snap device which mated
in a groove, or was held in such a way that caused a significant
reduction in light to the viewer.  The concept described herein
provides a non-obstructing lens mount for a LED indicator mounted
behind an opaque cover having an aperture.  The lens assembly is
pressed into the aperture so that light can be dispersed for greater
viewing outside of the cover.

      The figure is a perspective view showing the lens assembly in
position to be inserted into an aperature in the computer cover.  A
LED (not shown) mounted behind the aperature is located inside of
cover 11.  A rib 12 is molded onto each side of lens assembly 10 to
provide an interference fit against walls 13 of cover 11 when lens
assembly 10 is inserted into the aperature in cover 11.  The
interference fit is sufficient to hold lens assembly 10 in place
within the apertu...
