Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
54 words
A ring sizer comprising a generally cylindrical stick having a diameter which tapers from one end thereof to the other, said stick being formed of pliable, substantially seamless material and adapted to distort locally to accommodate the contour of a ring being sized while resisting distortion sufficiently to enable correct sizing of said ring.
Claim 2
Dependent Claim
54 words
A ring sizer comprising a generally cylindrical stick having a diameter which tapers from one end thereof to the other, said stick being formed of pliable, substantially seamless material and adapted to distort locally to accommodate the contour of a ring being sized while resisting distortion sufficiently to enable correct sizing of said ring.
Claim 3
Dependent Claim
22 words
A stick according to claim 1 having graduated sizing indicia along the external surface thereof for measuring the circumference of said ring.
Claim 4
Dependent Claim
25 words
A stick according to claim 1 in which at least the surface portions thereof are formed of a different pliable material than the interior portions.
Claim 5
Dependent Claim
15 words
A stick according to claim 3 wherein said surface portions are formed of flexible plastic.
Claim 6
Dependent Claim
67 words
A ring sizer comprising a generally cylindrical stick having a diameter which tapers from one end thereof to the other, said stick further comprising a rod formed of rigid material; and a shell formed of pliable material, said shell surrounding said rod and adapted to distort locally to accommodate the contour of a ring being sized while resisting distortion sufficiently to enable correct sizing of said ring.
Claim 7
Dependent Claim
67 words
A ring sizer comprising a generally cylindrical stick having a diameter which tapers from one end thereof to the other, said stick further comprising a rod formed of rigid material; and a shell formed of pliable material, said shell surrounding said rod and adapted to distort locally to accommodate the contour of a ring being sized while resisting distortion sufficiently to enable correct sizing of said ring.
Claim 8
Dependent Claim
22 words
