Abstract

Abstract Skates employing balls as the primary rolling elements may be used in lieu of roller skates for street hockey or indoors on wood floors, concrete or other hard surfaces. In the preferred form the skate includes two balls, preferably of semi-hardened rubber, metal, wood, plastic or the like, one in the front and one at the rear of the skate. Each ball is supported by a set of rolling supports which allow the ball to rotate freely in a forward or backward direction but inhibits rotation of the ball in other directions. The supports include at least two transverse shafts on which are mounted spaced rollers or rings of different diameters and contoured to mate with the upper portion of the ball. The different size rollers are independently rotatable on the shaft to compensate for the different surface speeds of the ball as it rolls forwards or backwards. Since the rollers can rotate only about the transverse axis of the shaft, the friction produced between the ball and the supports in a direction other than forwards and backwards inhibits sidewise movement of the skate. A pusher block is provided at the forward end of the skate allowing the wearer to push himself forwardly either by tipping the block against the skating surface or by a sidewise pushing motion much like an ice skate.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 120 words
A skate, comprising: (a) a frame, (b) means for attaching said frame to the foot of a person, (c) said frame defining at least a pair of downwardly open sockets, (d) a ball mounted for rotation in each of said sockets, (e) at least a pair of shafts mounted in spaced relation to said frame proximate to each socket and extending in a horizontal transverse direction with respect to the length of said frame, (f) a plurality of rings mounted for free independent rotation to at least one of said shafts and at least one ring mounted for rotation to another of said shafts, the periphery of each of said rings rotatably supporting said ball at the outer surface thereof.
Claim 2
Dependent Claim 120 words
A skate, comprising: (a) a frame, (b) means for attaching said frame to the foot of a person, (c) said frame defining at least a pair of downwardly open sockets, (d) a ball mounted for rotation in each of said sockets, (e) at least a pair of shafts mounted in spaced relation to said frame proximate to each socket and extending in a horizontal transverse direction with respect to the length of said frame, (f) a plurality of rings mounted for free independent rotation to at least one of said shafts and at least one ring mounted for rotation to another of said shafts, the periphery of each of said rings rotatably supporting said ball at the outer surface thereof.
Claim 3
Dependent Claim 17 words
A skate according to claim 1 wherein said sockets are located at opposite ends of said frame.
Claim 4
Dependent Claim 29 words
A skate according to claim 2 wherein a plurality of rings are mounted to two of said shafts with the rings on each shaft being of several different diameters.
Claim 5
Dependent Claim 29 words
A skate according to claim 3 wherein the outer periphery of each ring is profiled to conform with that portion of the ball in which it is in contact.
Claim 6
Dependent Claim 18 words
A skate according to claim 3 wherein the rings on each shaft are axially spaced from one another.
Claim 7
Dependent Claim 25 words
A skate according to claim 3 including a third shaft mounted to said frame above each ball and a single center ring rotatably mounted thereto.
Claim 8
Dependent Claim 22 words
A skate according to claim 1 including a removable plate mounted to said frame adjacent said socket for access to said ball.
Claim 9
Dependent Claim 18 words
A skate according to claim 1 including a resilient bumper mounted to the forward end of said frame.
Claim 10
Dependent Claim 15 words
A skate according to claim 3 wherein the peripheral edges of said rings are rounded.
Claim 11
Dependent Claim 16 words
A skate according to claim 1 wherein said means includes a shoe fixed to said frame.
