## Abstract

There is disclosed an improved roller skate having a unitary soleplate. The roller skate includes a pair or truck assemblies secured to the bottom surface of the soleplate at the toe portion and at the heel portion by a threaded fastener. The soleplate has an aperture for receiving each threaded fastener and a recess for receiving and confining an enlarged end portion of the fastener, and slot means in the soleplate, communicating with the aperture and the recess, allow insertion of the threaded fastener from the bottom of the soleplate.

## Claims

### Claim 1

A soleplate for a roller skate of the type including a truck assembly securable to the soleplate by a fastener assembly, said fastener assembly including an elongated shank member having a threaded end portion, said fastener assembly further including as components a head at an opposite end of said shank member and a nut engageable with the threaded end portion, the soleplate comprising: a unitary member having a top surface and a bottom surface, said unitary member including an embossment integral with and depending from said bottom surface, said embossment including an aperture through a bottom end thereof for receiving said shank member in a position depending from the soleplate, said aperture including axially aligned first and second portions respectively of first relatively large predetermined and second relatively small predetermined transverse dimensions and a seat between said first and second portions, at least one of the components having transverse dimensions less than said first and greater than said second predetermined transverse dimensions, said aperture further including a slot substantially transverse to said first and second portions and communicating therewith axially above said seat for passing one of said components and said shank member to said first and second portions during assembly of the fastener assembly with the soleplate, said one component having a side surface, said first portion having a surface engageable with said surface of said one component for preventing rotation of said component, said one component being movable through said slot, into said first portion and thence axially toward said second portion for engagement with said seat when fully assembled with said soleplate, tightening of said nut on said threaded portion causing the shank member to be non-rotatably and positively secured to said soleplate.

### Claim 2 (depends on 1)

The soleplate of claim 1 wherein said head is integral with said shank member; wherein the axis of said head is co-linear with the axis of said shank member; wherein said head and said first portion are hexagonal in transverse cross section, said first portion having relatively greater transverse dimensions than said head; and wherein said nut is relatively greater in transverse dimension than said second portion.

### Claim 3 (depends on 1)

The soleplate of claim 1 wherein said head is integral with said shank member; wherein the axis of said nut is co-linear with the axis of said shank member when said nut is engaged with said threaded end portion of said shank member; wherein said nut and said first portion are hexagonal in transverse cross section, said first portion having relatively greater transverse dimensions than said nut; and wherein said head is relatively greater in transverse dimensions than said second portion.
