ABSTRACT:
An adjustable magnifying apparatus comprising a generally rectangular-shaped, sheetlike magnifying surface, an adjustable arm having at least one generally hourglass-shaped member with a first end zone having a socket and an opposite, generally parabolic-shaped second end zone, a first coupler having a first end with a slit sized and shaped to removably secure an outer edge of the magnifying surface therein and an opposite, parabolic-shaped second end sized and shaped to be removably captured within the socket of one of the hourglass-shaped members, and a generally C-shaped clamp having a second coupler, structured and disposed to removably capture the parabolic-shaped second end zone of one of the hourglass-shaped members therein, mounted on the upper face. The socket, the parabolic-shaped second end zone of the hourglass-shaped members and the parabolic-shaped second end of the first coupler are sized and shaped so that the parabolic-shaped second end zone of one of the hourglass-shaped members or the parabolic-shaped second end of the first coupler may be removably captured within the socket of one of the hourglass-shaped members. Alternatively, the adjustable arm may be comprised of a torsional member structured so that the upper and lower ends may be adjustably disposed in angular relation to one another.
