Below are pictures, and a video, of the new, patent pending, bookstand.

 

Bookstand closed with lever arm sticking out of the left side.
Bookstand open on first or second notch.
Back of bookstand. Slots on bottom don't need to be that wide.
Another view.
Open to show mechanism.
Closeup of mechanism. Small wood part with 2 silver-looking screws are on the prototype only. Production version would have smaller cut-out. This cutout was for a specialized hinge design.

Hinge and support arm width will likely need to be larger than shown due to sloppiness in the hinge.
Close from right side.
Bookstand with book on it.
Hand on bookstand to show size perspective.
This video takes a few minutes to download. Be patient. It is a short movie (2 minutes) that shows the features of the bookstand.
