Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 241 words
An artificial fingernail attachable to a natural fingernail having a forward generally convex edge, said artificial fingernail comprising (a) a thin plastic sheet element sized to provide a forward extension of the natural fingernail, said element extending generally horizontally, (b) said element having a rearwardly concave crescent shaped distal edge and forming a recess below said edge to receive and conform generally to the shape of the convex forward edges of the natural fingernail; (c) there being a rearwardly concave crescent shaped stop at the proximal underside of the artificial fingernail in spaced relation to said rearward distal edge, the stop extending everywhere vertically and located to abut the natural fingernail forward edge to position the artificial fingernail so that an underside portion of the artificial fingernail may overlap and be bonded to an upper surface portion of the natural nail, (d) the artificial fingernail including two rearwardly projecting cusps toward which extremities of both said crescent shaped, rearward distal edge and said crescent shaped stop extend in generally rearwardly directions, the curvature of said crescent shaped rearward distal edge being lesser than the curvature of said crescent shaped stop, the stop spaced forwardly of said distal edge at a distance which becomes a maximum proximate a forwardly extending medial axis defined by the sheet element, said maximum distance being substantially less than the forward dimension from either cusp to a plane normal to said axis and tangent to said stop.
Claim 2
Dependent Claim 241 words
An artificial fingernail attachable to a natural fingernail having a forward generally convex edge, said artificial fingernail comprising (a) a thin plastic sheet element sized to provide a forward extension of the natural fingernail, said element extending generally horizontally, (b) said element having a rearwardly concave crescent shaped distal edge and forming a recess below said edge to receive and conform generally to the shape of the convex forward edges of the natural fingernail; (c) there being a rearwardly concave crescent shaped stop at the proximal underside of the artificial fingernail in spaced relation to said rearward distal edge, the stop extending everywhere vertically and located to abut the natural fingernail forward edge to position the artificial fingernail so that an underside portion of the artificial fingernail may overlap and be bonded to an upper surface portion of the natural nail, (d) the artificial fingernail including two rearwardly projecting cusps toward which extremities of both said crescent shaped, rearward distal edge and said crescent shaped stop extend in generally rearwardly directions, the curvature of said crescent shaped rearward distal edge being lesser than the curvature of said crescent shaped stop, the stop spaced forwardly of said distal edge at a distance which becomes a maximum proximate a forwardly extending medial axis defined by the sheet element, said maximum distance being substantially less than the forward dimension from either cusp to a plane normal to said axis and tangent to said stop.
