Abstract
Abstract A microscope stand and armrest system for placement on a conventional desktop includes height adjustment/levelling feet at each corner of a base plate and a top surface hingedly attached to the base plate for receiving a microscope and for tilting the microscope rearward toward the user to a position that allows the user to look directly forward when operating the microscope. Left and right sloping armrests are provided for placement on the desktop at each side of the microscope stand to support the user's forearms in natural positions while operating the microscope.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
220 words
A microscope stand and armrest system for placement on a fixed horizontal surface comprising: a base plate having a plurality of height adjustment/levelling feet attached to an underside thereof; a top plate coextensively positioned over said base plate for receiving a microscope thereon, said base plate and said top plate being hingedly attached at rearward edges thereof such that said top plate may be angularly elevated with respect to the horizontal to thereby tilt the microscope received thereon rearward toward the user; tilt control means engaging said base plate and said top plate for maintaining said top plate in a desired position of angular elevation, said tilt control means comprising a plurality of spaced apart grooves provided on a top surface of said base plate, a plurality of spaced apart grooves correspondingly provided on a bottom surface of said top plate, and a space bar adapted to matingly engage corresponding ones of said pluralties of grooves in said base plate and said top plate; and left and right armrest members positioned on said fixed horizontal surface to the left and right of said base plate for receiving a user's forearms, each of said left and right armrest members having a horizontal top surface proximate a forward edge thereof and a downward sloping top surface rearward of said horizontal top surface.
