Abstract
Abstract A uni-wheel skate has a circular wheel which has a rim arranged to rotate about a frame having a generally tilted axis so that the rim rotates in a plane which is generally tilted relative to the vertical. The frame has satellite rollers rotatably attached to the frame and engaging the rim so as to permit the rim to rotate about the frame. A foot support is pivotally carried by the frame and receives the rider's foot for transmission of the rider's body load to and through the frame to the wheel. A separate support is associated with the frame to be rotatable relative to the frame to be engaged with the rider's leg to maintain stability. The pivotable foot support may be provided with brake pads for engaging the rim.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
150 words
A uni-wheel skate, comprising (a) a circular wheel having a rim arranged to rotate about a generally tilted axis so that the rim rotates in a plane which is generally tilted relative to vertical, (b) a frame relative to which the rim rotates, (c) satellite rollers rotatably attached to the frame and engaging the rim so as to determine the relative rotation of the rim with respect to the frame, and (d) support means carried by the frame to receive the load of the rider's foot for transmission of the rider's body load to and through the frame and rollers to the wheel, said support means comprising a foot plate which is rotatably mounted to the frame to be rotatable relative thereto, (e) and including a separate support associated with the frame to be rotatable relative to the frame, said separate support engageable with the rider's leg to maintain stability.
Claim 2
Dependent Claim
150 words
A uni-wheel skate, comprising (a) a circular wheel having a rim arranged to rotate about a generally tilted axis so that the rim rotates in a plane which is generally tilted relative to vertical, (b) a frame relative to which the rim rotates, (c) satellite rollers rotatably attached to the frame and engaging the rim so as to determine the relative rotation of the rim with respect to the frame, and (d) support means carried by the frame to receive the load of the rider's foot for transmission of the rider's body load to and through the frame and rollers to the wheel, said support means comprising a foot plate which is rotatably mounted to the frame to be rotatable relative thereto, (e) and including a separate support associated with the frame to be rotatable relative to the frame, said separate support engageable with the rider's leg to maintain stability.
Claim 3
Dependent Claim
21 words
The skate of claim 1 wherein said plate means has a foot support surface located below the level of said axis.
Claim 4
Dependent Claim
32 words
The skate of claim 1 including brake means operable in response to rotation of the foot plate relative to the frame, said brake means including brake pad means engageable with the rim.
Claim 5
Dependent Claim
39 words
The skate of claim 3 wherein said brake pad means includes fore and aft brake pads on the footplate and respectively engageable with the rim in response to fore and aft rocking of the footplate relative to the frame.
Claim 6
Dependent Claim
23 words
The skate of claim 3 including stop means on the frame to limit said rotation of said separate support relative to the frame.
Claim 7
Dependent Claim
28 words
The skate of claim 5 wherein said stop means include fore and aft stops respectively located on the frame in fore and aft relation to said separate support.
Claim 8
Dependent Claim
36 words
The skate of claim 6 wherein the stops are positioned in the paths of rotation of the separate support to be engaged thereby, allowing said footplate rocking by the rider's foot, and relative to the frame.
Claim 9
Dependent Claim
27 words
The skate of claim 5 including yieldable means for yieldably resisting rotation of the footplate relative to the frame, prior to said operation of the brake means.
Claim 10
Dependent Claim
31 words
The skate of claim 8 wherein said yieldable means include fore and aft springs respectively located on the footplate in fore and aft association with said fore and aft brake pads.
Claim 11
Dependent Claim
30 words
The skate of claim 1 wherein said satellite rollers include two rollers above the level of said wheel axis, and a single roller below the level of said wheel axis.
Claim 12
Dependent Claim
44 words
The skate of claim 1 wherein said satellite rollers include at least one roller below the level of said wheel axis, and said one roller defines a second axis of rotation, said footplate and said separate support also being rotatable about said second axis.
Claim 13
Dependent Claim
29 words
The skate of claim 1 wherein said satellite rollers include one roller above the level of said wheel axis, and two rollers below the level of said wheel axis.
Claim 14
Dependent Claim
21 words
The skate of claim 1 wherein said satellite rollers are grooved to pass a valve stem associated with the wheel rim.
Claim 15
Dependent Claim
16 words
The skate of claim 1 wherein said satellite rollers have flanges located to straddle the rim.
Claim 16
Dependent Claim
31 words
The skate of claim 1 wherein said rim is resiliently flexible to assume a slightly out-of-round configuration under variable loading imposed by a rider on the footplate or by the roadway.
Claim 17
Dependent Claim
16 words
The skate of claim 15 wherein the flexible rim is grooved to receive said satellite rollers.
Claim 18
Dependent Claim
15 words
The skate of claim 1 wherein said rim is grooved to receive said satellite rollers.
Claim 19
Dependent Claim
14 words
The skate of claim 1 wherein said leg support is carried by the frame.
Claim 20
Dependent Claim
21 words
The skate of claim 1 wherein said separate support is pivotally mounted to rotated about an axis defined by the rim.
Claim 21
Dependent Claim
17 words
