Abstract
Abstract A small magnifying glass is secured to an edge encompassing surrounding portion of a frame, which integrally continues on beyond the magnifying glass in serrated apart opposite hand extending supports to create an adjustable thumb or finger surrounding portion. This finger portion of the frame is preceded and followed by openings which are also formed by the opposite hand extending supports to create a laterally compressible and expandable resilient thumb or finger mountable overall supporting frame of this extra hand magnifying glass.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
248 words
An extra hand magnifying glass assembly resiliently, compressibly and comfortably supportable on a person's thumb or finger to provide a magnifying glass to be used during reading and sewing, comprising: (a) a magnifying glass; (b) a one piece body arranged in one geometric plane and made of moldable resilient plastic material, comprising, in turn: (1) a completely surrounding edge receiving structure at the top to fully receive the entire peripheral edge structure of the magnifying glass; (2) a set of depending opposite hand multiple curved structures, each at their tops being integral with the completely surrounding edge receiving structure and depending therefrom and being spaced apart from one another, their multiple curved structures being formed first below the magnifying glass, to create together a resulting small flexible circular opening, second, below this small flexible circular opening, to create together a resulting larger flexible circular opening to resiliently, compressibly, and comfortably receive a person's thumb or finger, and third below this larger flexible circular opening receiving a thumb or finger, to create a crossover lever arms to which a compressive force is applied to move the crossover lever arms together and thereby to relatively move the set of depending opposite hand multiple curved structures temporarily enlarging the second larger flexible circular opening to receive and thereafter to close comfortably around a person's thumb or finger, and (c) a means to hold the magnifying glass within the completely surrounding edge receiving structure at the top of the one piece body.
