Abstract
Abstract A magnifying lens holder assembly comprising a frame having a magnifying lens mounted therein, said frame being pivotally connected to an elongated arm whereby the frame may fold against said arm, and a case pivotally receiving said arm, whereby said arm, with the frame folded thereagainst, may be swung into said case to be enclosed thereby, said case having opposed resilient portions for receiving a user's finger, a pen, a flashlight or the like, a pivotally mounted supporting member for maintaining said case in upstanding position on a flat supporting surface, a finger clamp for slidingly receiving a card or the like, and clip means for enabling the case to be selectively attached to a wearer's pocket or to the temple bar of eyeglasses.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
153 words
A magnifying lens holder assembly comprising a frame in which said lens is mounted, an elongated arm pivotally connected at one end to said frame, a case for receiving said frame and arm assembly, said case comprising a pair of spaced side walls interconnected by a top wall but otherwise substantially open at its side and bottom edges, means defining a socket located at one end of said top wall, a ball member at the other end of said arm swivelly received by said socket, whereby when said assembly is not in use, said frame may be pivoted so as to fold against said arm, and then said arm and frame may be swung about said ball and socket to a position wherein said arm and frame are enclosed within said walls, said side walls having oppositely disposed gently curved portions at their lower extremity for resiliently and clampingly receiving the user's finger.
Claim 2
Dependent Claim
153 words
A magnifying lens holder assembly comprising a frame in which said lens is mounted, an elongated arm pivotally connected at one end to said frame, a case for receiving said frame and arm assembly, said case comprising a pair of spaced side walls interconnected by a top wall but otherwise substantially open at its side and bottom edges, means defining a socket located at one end of said top wall, a ball member at the other end of said arm swivelly received by said socket, whereby when said assembly is not in use, said frame may be pivoted so as to fold against said arm, and then said arm and frame may be swung about said ball and socket to a position wherein said arm and frame are enclosed within said walls, said side walls having oppositely disposed gently curved portions at their lower extremity for resiliently and clampingly receiving the user's finger.
Claim 3
Dependent Claim
58 words
In the assembly of claim 1, the other end of said top wall being cut away to define a shoulder, and a finger member extending integrally from said side walls into adjacent spaced relation with said shoulder, said finger member and said shoulder defining a resilient clamp for slidably receiving flat articles, such as cards and the like.
Claim 4
Dependent Claim
72 words
In the assembly of claim 1, said top wall comprising two identical sections, each section having one of said side walls depending therefrom and each section carrying a part of said socket, means securing said sections together to complete the assembly, the diameter of said ball member being slightly larger than that of said socket, whereby a frictional drag is imparted on said ball member as the latter rotates within said socket.
Claim 5
Dependent Claim
25 words
In the assembly of claim 3, said securing means comprising screws, whereby tightening of said screws correspondingly increases the frictional drag on said ball member.
Claim 6
Dependent Claim
55 words
In the assembly of claim 1, a supporting foot member pivotally connected to said case adjacent the other end of said top wall, said foot member being movable between a retracted inoperative position and an extended operative position wherein said case may be positioned on its adjacent side edge on a flat surface without tipping.
Claim 7
Dependent Claim
15 words
In the assembly of claim 5, said foot member having calibrations on its top edge.
Claim 8
Dependent Claim
22 words
In the assembly of claim 5, integral detent means on said case for releasably retaining said foot member in its inoperative position.
Claim 9
Dependent Claim
81 words
In the assembly of claim 1, a clip member secured to the outer surface of one of said side walls, said clip member comprising an elongated curved arm making resilient engagement with said side wall adjacent the free extermity of said arm, and a resilient tongue integrally formed in said arm and extending reversely from a point adjacent said free end, said tongue being substantially straight and having a bead on its inner surface adjacent the free end of said tongue.
Claim 10
Dependent Claim
19 words
In the assembly of claim 1, the pivotal connection between said arm and said frame comprising releaseable snap-on connection.
