Adjustable Stereoscopic Slide Viewer

       Disclosed is an adjustable stereoscopic slide viewer that
uses a gusset to vary eyepiece separation and facilitate the
stereoscopic view.  Focal distance is adjustable and the viewer
collapses for easy shipment and storage.

      The eyepieces in most stereoscopic viewers are a fixed distance
apart, but eye spacing varies significantly among users.  It is
important that the eyepiece spacing match a user's eye spacing to
facilitate the stereoscopic view.  To our knowledge, there are no
viewers available that both vary the eyepiece separation and fold
conveniently.

      The figure shows the design of the adjustable stereoscopic
slide viewer.  The gusset is located midway between the eyepieces.
Small gaps in the gusset allow the intervening segments to bend
without interfering with each other.

      The viewer is constructed of a flexible material, such as
cardboard, that allows adjusting the eyepiece separation and focal
distance and folding the viewer flat for storage or mailing.  The
gusset is also constructed of a flexible material and the user pushes
or pulls on the viewer to change the distance between the eyepieces.
Creases along the top, bottom, and side flaps of the housing allow
adjustment of the focal distance.  The creases in the housing and the
flexibility of the gusset allow the viewer to be folded nearly flat.
The interior of the viewer is colored black to minimize internal
reflection from the small amount of light that enters the gaps in the
gusset and the space...
