Abstract
Abstract A skate wheel includes a reusable hub and a replaceable tire. The hub consists of (i) a rim with an integral clamp ring, (ii) an attachable clamp ring that attaches to the rim after a tire is mounted on the rim and (iii) a threaded ring which fastens onto the rim and secures the attachable clamp ring to the rim. Each of the clamp rings includes an inwardly pointing arm. These arms extend into annular grooves on the sides of the tire, to grip the tire and hold it in place on the rim. In a preferred embodiment the outer ring screws onto the rim and in position against the clamp ring, to retain the claim ring on the rim. To replace a worn tire, a user unscrews the outer ring, removes the attachable clamp ring and then removes the old tire from the rim. He then slides a new tire onto the rim, holds the tire in place with the attachable clamp ring and secures that ring in place with the outer ring.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
190 words
A wheel for skates, the wheel including: A. a hub for attaching the wheel to the skate, said hub including i. a hollow rim with an integral clamp ring, the ring including an inwardly pointing first arm for gripping a tire and a center action that extends inwardly from the clamp ring, ii. an attachable clamp ring that slideably mounts on the center section of the rim, the ring including an inwardly pointing second arm for gripping a tire, the clamp ring sliding unimpeded onto the center section until the arm rests against the tire; and iii. an outer ring that reacts against the attachable clamp ring and fastens to the center section of the rim, the outer ring applying to the slideably-mounted attachable clamp ring a force that is sufficient to hold the tire in place the attachable clamp ring being prevented from further movement onto the center section only by the tire; and B. a hardened tire that mounts on the rim before the attachable claim ring is slideably mounted on the rim, the tire including annular grooves that receive the inwardly pointing arms of the clamp rings.
Claim 2
Dependent Claim
42 words
The wheel of claim 1, wherein a. the rim includes on the center section, at an end opposite the integral clamp ring, threads for receiving the outer ring; and b. the outer ring is a threaded ring that screws onto the rim.
Claim 3
Dependent Claim
19 words
The wheel of claim 2, wherein the attachable clamp ring includes a recess into which the outer ring fits.
Claim 4
Dependent Claim
186 words
A reusable hub for a skate wheel, the hub supporting a hardened tire and including: A. a rim with an integral clamp rang, the ring including an arm for gripping the hardened tire and a center section that extends outwardly from the integral clamp ring in the same direction as the arm, the center section including an outer cylindrical surface and at an end opposite the integral clamp ring screw threads; B. an attachable clamp ring that slideably mounts on the outer surface of center section of the rim, the ring including an inwardly pointing arm for holding the tire in place on the rim, and attachable clamp ring sliding unimpeded on the cylindrical surface of the center section until the arm meets the hardened tire; and C. an outer ring for screwing onto the threads of the rim the ring securing the attachable clamp ring to the rim and applying a force to the attachable clamp ring that is sufficient to hold the hardened tire in place the attachable clamp ring being prevented from further axial movement on the center section only by the tire.
Claim 5
Dependent Claim
186 words
A reusable hub for a skate wheel, the hub supporting a hardened tire and including: A. a rim with an integral clamp rang, the ring including an arm for gripping the hardened tire and a center section that extends outwardly from the integral clamp ring in the same direction as the arm, the center section including an outer cylindrical surface and at an end opposite the integral clamp ring screw threads; B. an attachable clamp ring that slideably mounts on the outer surface of center section of the rim, the ring including an inwardly pointing arm for holding the tire in place on the rim, and attachable clamp ring sliding unimpeded on the cylindrical surface of the center section until the arm meets the hardened tire; and C. an outer ring for screwing onto the threads of the rim the ring securing the attachable clamp ring to the rim and applying a force to the attachable clamp ring that is sufficient to hold the hardened tire in place the attachable clamp ring being prevented from further axial movement on the center section only by the tire.
