Abstract
Abstract A hopping and dancing shoe comprises a sole member, a base member parallel thereto, and a spring therebetween. Two means are provided by the spring to resist yawing of the sole member relative to the base member: (1) the spring has an axial extension of each end which is connected to the sole member and base member, respectively; and (2) the extreme outer coils of the spring are in contact with the sole member and base member, respectively, to provide frictional contact there between.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
127 words
Hopping shoe comprising a sole member, a base member spaced from said sole member and a spring having outer coils in spaced parallel planes which are perpendicular to the axis of said coils and outer axial end portions, said spring having a diameter substantially equal to the width of said sole member and said base member, and connection means fixedly attaching said sole and said base to the axial outer ends of said spring, said connection means also positioning said sole and said base to come into contact with its juxtapositioned outer diameter coil of said spring wherein the static weight of the shoe wearer will unify, for rotational displacements, said sole and said base by friction to its justapositioned outer full diameter coil of said spring.
Claim 2
Dependent Claim
127 words
Hopping shoe comprising a sole member, a base member spaced from said sole member and a spring having outer coils in spaced parallel planes which are perpendicular to the axis of said coils and outer axial end portions, said spring having a diameter substantially equal to the width of said sole member and said base member, and connection means fixedly attaching said sole and said base to the axial outer ends of said spring, said connection means also positioning said sole and said base to come into contact with its juxtapositioned outer diameter coil of said spring wherein the static weight of the shoe wearer will unify, for rotational displacements, said sole and said base by friction to its justapositioned outer full diameter coil of said spring.
Claim 3
Dependent Claim
66 words
Hopping shoe according to claim 1 wherein said sole and said base have cavities therein and said connection means includes a bolt and a nut which reside in the cavities in said sole and said base so that no portion of said bolt or said nut protrude to touch the wearer of the shoe or the supporting surface which can come into contact with said sole.
Claim 4
Dependent Claim
17 words
A hopping shoe according to claim 1 including a castanet, or the like, attached to said shoe.
Claim 5
Dependent Claim
19 words
Hopping shoe according to claim 1 wherein both outer coils of said spring are substantially of the same diameter.
