Abstract
Abstract A novel roller skating device includes the combination of a boot having the general appearance of an ice skate boot, including a rear section adjacent the region of the tibia extending beyond the region of the Achilles tendon. The rear section extends along the sides of the boot and curvingly projects above the region of the malleoli. An additional section of the boot surface follows the region of the instep, from a section abutting the rear section, in order to provide rows of lace accepting holes. The rows of lace accepting holes end just above the region of the toe joints. The skating device includes a front roller assembly secured to the toe portion area of the boot, and a rear roller assembly secured to the heel portion area of the boot. Each of the front roller assembly and the rear roller assembly includes a bridge sub-assembly of an inverted generally U-frame shape, including a base and a pair of spaced preferably inwardly prestressed depending wings, and a hollow spheroidal roller having axially disposed, diametrically opposed bearing surfaces, rotatably operatively engaged with respect to the spaced apart wings, the hollow roller being a globular roller comprising a hollow spheroidal, inner, rigid relatively thin walled core of structurally strong material, covered by a coating of a resilient material thereon. The base section of the forward roller assembly is centrally positioned and disposed below the matatarsal head. A rear roller assembly is also secured to the heel portion of the rear assembly. The rear member has a base section centrally positioned and disposed below the calcaneous. The apex of the inverted generally U-shaped members form an axle for the globular rollers for both the front roller assembly and the rear roller assembly.
