Claim 1
Independent Claim
302 words
A prosthetic nail adapted for use on one of the digits of a person's hand or foot, comprising the combination of: (a) a nail plate comprising a sheet having front and rear ends and a longitudinal axis extending therebetween, and the plate being adapted to be placed on top of the distal end of a digit so that the longitudinal axis extends in the same general direction as to the distal phalangeal bone of the digit, and said plate being slightly curved as viewed in a transverse plane so as to approach the generally cylindrical cross-sectional shape of a typical digit, and said plate having a thin edge at its rear end that is adapted to be at least partially buried within the eponychial fold of the digit; and (b) a bifurcated anchor member extending downwardly from near the front end of the nail plate, and said anchor member having two legs with proximal and distal portions, and the distal portions of the legs having a rest condition at which they are spaced apart appreciably further than are their proximal portions, and said distal portions being susceptible of being temporarily brought together so that the distal portions are essentially as close as are the proximal portions, and the two legs lying in a transverse plane where they are exposed to being externally gripped from the front of the nail plate, whereby the nail plate is held in place on a digit when the leg distal portions are in their rest condition and when they are in contact with a pocket of tissue on the forward end of a person's digit, and whereby said leg distal portions may be temporarily brought together so that the anchor member may be lifted vertically away from the person's nail bed without damaging the pocket of tissue.
Claim 2

A prosthetic nail adapted for use on one of the digits of a person's hand or foot, comprising the combination of: (a) a nail plate comprising a sheet having front and rear ends and a longitudinal axis extending therebetween, and the plate being adapted to be placed on top of the distal end of a digit so that the longitudinal axis extends in the same general direction as to the distal phalangeal bone of the digit, and said plate being slightly curved as viewed in a transverse plane so as to approach the generally cylindrical cross-sectional shape of a typical digit, and said plate having a thin edge at its rear end that is adapted to be at least partially buried within the eponychial fold of the digit; and (b) a bifurcated anchor member extending downwardly from near the front end of the nail plate, and said anchor member having two legs with proximal and distal portions, and the distal portions of the legs having a rest condition at which they are spaced apart appreciably further than are their proximal portions, and said distal portions being susceptible of being temporarily brought together so that the distal portions are essentially as close as are the proximal portions, and the two legs lying in a transverse plane where they are exposed to being externally gripped from the front of the nail plate, whereby the nail plate is held in place on a digit when the leg distal portions are in their rest condition and when they are in contact with a pocket of tissue on the forward end of a person's digit, and whereby said leg distal portions may be temporarily brought together so that the anchor member may be lifted vertically away from the person's nail bed without damaging the pocket of tissue.
Claim 3
Dependent Claim
93 words
The prosthetic nail as claimed in claim 1 wherein the bifurcated anchor member is located very close to the front end of the nail plate, and wherein a significant gap is provided between the two legs of the anchor member, and the outside surfaces of said legs being configured so as to be engageable by the two jaws of a pair of tweezers, whereby the anchor member may be released from its holding mode to its release mode by squeezing tweezers around the two legs of the anchor member in a transverse direction.
Claim 4
Dependent Claim
58 words
The prosthetic nail as claimed in claim 1 wherein the anchor member is molded from a plastic material having an inherent resilience and a sufficient memory as to cause the legs to return to their extended positions within a relatively short period of time after a compressing force has been removed from the outer surfaces of said legs.
Claim 5
Dependent Claim
36 words
The prosthetic nail as claimed in claim 1 wherein the distal ends of the two legs are separated by a distance that is at least twice the narrowest distance between the proximal ends of the legs.
Claim 6
Dependent Claim
69 words
The prosthetic nail as claimed in claim 1 wherein the distal ends of the two legs are separated by a distance which is approximately 3 mm greater than the distance separating the proximal portions of said legs, whereby there is a potential of holding the prosthetic nail on a person's digit by having tissue overlie the distal portions of the two legs by as much as approximately 3 mm.
Claim 7
Dependent Claim
26 words
The prosthetic nail as claimed in claim 1 wherein each of the legs extends downwardly from its attachment point for a distance of about 41/2 mm.
