Abstract

Abstract Disclosed herein is convertible footwear in the nature of roller skates which may be simply and easily converted to use as walking shoes by placing uniquely configured wear surfaces over the wheels which automatically lock the wheels against rotation. Advantageously, and in accordance with the invention, the wear surfaces and wheel locking means are a single integral unit which may be molded from suitable synthetic or natural rubber or other elastomeric materials.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 75 words
A removable walking sole construction for roller skates having at least one pair of tandem skate wheels, said sole contruction comprising a. a first and second wear surface means for covering at least the bottom portions of each of said skate wheels; b. clamping means for securely engaging each of said tandem skate wheels; and c. substantially rigid stabilizing means interconnecting said clamping means and for cooperating therewith to prevent the rotation of said wheels.
Claim 2
Dependent Claim 75 words
A removable walking sole construction for roller skates having at least one pair of tandem skate wheels, said sole contruction comprising a. a first and second wear surface means for covering at least the bottom portions of each of said skate wheels; b. clamping means for securely engaging each of said tandem skate wheels; and c. substantially rigid stabilizing means interconnecting said clamping means and for cooperating therewith to prevent the rotation of said wheels.
Claim 3
Dependent Claim 25 words
The sole construction of claim 1, in which a. said wear surface means, clamping means, and stabilizing means are integrally formed of an elastomeric material.
Claim 4
Dependent Claim 23 words
The sole of claim 2, in which a. said elastomeric material is selected from the group consisting of natural rubber and synthetic rubber.
Claim 5
Dependent Claim 51 words
The sole of claim 1, in which a. said clamping means is an expandable, completely circular, closed loop having an inner diameter, in its relaxed condition, slightly less than the outer diameter of said wheels, and being sufficiently stretchable to be fitted over and about the peripheral surfaces of said wheels.
Claim 6
Dependent Claim 42 words
The sole of claim 4, in which a. said stabilizing means is in the form of a vertical plate means extending between said clamping means and having parallel flanges extending outwardly therefrom, thereby giving said stabilizing means a generally I-shaped cross section.
Claim 7
Dependent Claim 40 words
The sole construction of claim 1, which further includes a. a separate, second sole construction identical to that defined in claim 1, subparagraphs (a) (b) and (c); and b. a hang strap means interconnecting each of said separate sole constructions.
Claim 8
Dependent Claim 27 words
The sole construction of claim 6, further characterized in that a. Said separate sole constructions and said strap means are integrally formed and comprise a single unit.
Claim 9
Dependent Claim 118 words
Convertible footwear comprising a. a shoe body; b. a pair of skate trucks mounting two pairs of rotatable skate wheels in tandem; c. means affixing said skate trucks to said shoe body; d. removable restraining means engaging each of said wheels and preventing the rotation thereof; and e. removable wear surface means associated with said restraining means and providing a selectively removable walking sole for said shoe body; f. whereby said footwear is adapted for normal walking use when said skate wheels are restrained and said wear surface means is in place and alternatively, said footwear is adapted to be instantly converted to a roller skate upon the removal of said restraining means and said wear surface means.
Claim 10
Dependent Claim 118 words
Convertible footwear comprising a. a shoe body; b. a pair of skate trucks mounting two pairs of rotatable skate wheels in tandem; c. means affixing said skate trucks to said shoe body; d. removable restraining means engaging each of said wheels and preventing the rotation thereof; and e. removable wear surface means associated with said restraining means and providing a selectively removable walking sole for said shoe body; f. whereby said footwear is adapted for normal walking use when said skate wheels are restrained and said wear surface means is in place and alternatively, said footwear is adapted to be instantly converted to a roller skate upon the removal of said restraining means and said wear surface means.
Claim 11
Dependent Claim 32 words
The convertible footwear of claim 7, in which a. said wear surface means and said restraining means for each pair of tandem wheels are integrally formed as a one-piece molded resilient element.
Claim 12
Dependent Claim 16 words
The convertible footwear of claim 8, in which a. said wear surface means includes molded-in treads.
Claim 13
Dependent Claim 37 words
The convertible footwear of claim 10, in which a. said treads comprise a plurality of parallel ridges extending completely across said wear surface means; b. said treads are perpendicular to the longitudinal axis of said shoe body.
