Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
120 words
A hair-slide which includes a base comprising a strip portion, a spring pivoting in relation to said base about a transverse hinge located adjacent one end of said base and which has a central arched portion above said strip, a flexible clasp pivoting in relation to said base about a second transverse hinge located adjacent the other end of said base and which is formed with a long opening along its length into which penetrates said central spring portion when said clasp is in its closed position, the free end of said clasp, when it is in its closed position, being held in place, in the absence of a pressure exerted on the spring, by a portion of said spring.
Claim 2
Dependent Claim
120 words
A hair-slide which includes a base comprising a strip portion, a spring pivoting in relation to said base about a transverse hinge located adjacent one end of said base and which has a central arched portion above said strip, a flexible clasp pivoting in relation to said base about a second transverse hinge located adjacent the other end of said base and which is formed with a long opening along its length into which penetrates said central spring portion when said clasp is in its closed position, the free end of said clasp, when it is in its closed position, being held in place, in the absence of a pressure exerted on the spring, by a portion of said spring.
Claim 3
Dependent Claim
54 words
A hair-slide according to claim 1 wherein said spring is formed adjacent its hinge with a widened portion formed with an opening therein located externally of this hinge, and wherein that portion of said spring which is located externally of said opening forms said spring portion which holds said clasp in its closed position.
Claim 4
Dependent Claim
27 words
A hair-slide according to claim 2 wherein said widened portion comprises the hinge of said spring and is curved oppositely to the central portion of said spring.
Claim 5
Dependent Claim
56 words
A hair-slide according to claim 2 wherein said widened portion includes a first part from which stems said spring hinge moving between the lateral bearings thereof, and externally of said first part, a second wider part of which the pivotal motion which moves said central spring portion towards said base is arrested by said lateral bearings.
Claim 6
Dependent Claim
67 words
A hair-slide according to claim 1 wherein said spring is formed adjacent its hinge with a widened portion formed with an opening therein located externally of this hinge, said widened portion being formed with two transverse protrusions projecting into said opening, and wherein that portion of said spring which is located externally of said opening forms said spring portion which holds said clasp in its closed position.
Claim 7
Dependent Claim
60 words
A hair-slide according to claim 1 wherein said spring is formed adjacent its hinge with a widened portion formed with an opening therein located externally of this hinge, and wherein that portion of said spring which is located externally of said opening is shaped as a two-pronged fork the handle portion of which is formed by said central spring portion.
Claim 8
Dependent Claim
35 words
A hair-slide according to claim 6 wherein the sum of the transverse linear sections of the parallel portions of the two fork prongs is greater than the transverse linear section of said central spring portion.
Claim 9
Dependent Claim
35 words
A hair-slide according to claim 1 wherein that portion of the spring which is adjacent the free end thereof is located between the strip portion of said base and the hinge axis of said clasp.
