Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
257 words
A magnifier viewer and stand having a one-piece base consisting of a rectangular sheet of synthetic resin formed in a continuous shape defining a flat horizontally disposed front portion, an upwardly extending compound curved portion adjacent said front portion and extending transversely of said base, the longitudinal edges of said curved portion being disposed on the plane of said flat front portion, an upwardly angled inclined portion adjacent said curved portion on the opposite edge thereof with respect to said front portion, said inclined portion arranged to support an opened book to be viewed with said book engaging said curved portion, a downwardly angled portion adjacent said inclined portion having a transversely extending lower section on said plane of said front portion, a secondary curved portion adjacent said lower section of said downwardly angled portion and extending transversely of said base, said secondary curved portion forming the terminal back edge of said one-piece base, transversely extending spaced slits in said flat front portion defining a band like section therebetween raised with respect to said plane of said front portion and a rectangular molded magnifier lens of a size comparable with said inclined portion of said base, a support arm for said lens, said support arm being curved between its ends to define a flat extension on one end slidably disposed beneath said band-like section of said front portion and an angled extension on its other end engaging said lens arranged to position said lens on the same angle as said upwardly angled inclined portion of said base.
