Abstract
Abstract The device includes first and second pads each of which is adapted to support one leg of a person. The pads are rigidly interconnected together. Each pad has a ground engaging element below and associated therewith. A generally spherical bearing is provided between each ground engaging element and its associated pad so that each pad may tilt and/or rotate relative to its ground engaging element.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
136 words
An amusement and/or exercising device comprising first and second pads spaced from each other, each pad being adapted to support one leg of a person, means extending between and rigidly interconnecting said pads, a discrete ground engaging element below and associated with each pad, the improvement comprising means defining a bearing socket approximately 3/4 of a sphere on the bottom of each pad, a generally spherical bearing in each socket, each bearing being rigidly connected to one of said ground engaging elements, each pad being pivotable relative to its associated element through a limited art to thereby facilitate tilting the pads as a unit so that one pad is higher than the other and off the ground, and each bearing permitting its pad to rotate relative to its associated ground engaging element about a vertical axis.
Claim 2
Dependent Claim
136 words
An amusement and/or exercising device comprising first and second pads spaced from each other, each pad being adapted to support one leg of a person, means extending between and rigidly interconnecting said pads, a discrete ground engaging element below and associated with each pad, the improvement comprising means defining a bearing socket approximately 3/4 of a sphere on the bottom of each pad, a generally spherical bearing in each socket, each bearing being rigidly connected to one of said ground engaging elements, each pad being pivotable relative to its associated element through a limited art to thereby facilitate tilting the pads as a unit so that one pad is higher than the other and off the ground, and each bearing permitting its pad to rotate relative to its associated ground engaging element about a vertical axis.
Claim 3
Dependent Claim
23 words
A device in accordance with claim 1 wherein each element has a flat bottom surface and is integrally connected to its associated bearing.
Claim 4
Dependent Claim
42 words
A device in accordance with claim 1 wherein each said socket is provided with a conical hole on the lower end thereof, each bearing being connected to its associated ground engaging element therebelow by a shaft extending through one of said holes.
Claim 5
Dependent Claim
72 words
A device in accordance with claim 1 including an annular enclosure having one end removably coupled to each pad and its other end removably coupled to the associated ground engaging element, said enclosure being made from an elastomeric material, the coupling of said ends of said enclosure being arranged so as not to interfere with the ability of each pad to rotate through 360° with respect to its associated ground engaging element.
Claim 6
Dependent Claim
16 words
A device in accordance with claim 1 wherein the length of said interconnecting means is adjustable.
Claim 7
Dependent Claim
162 words
An amusement and/or an exercising device comprising first and second pads, each pad being adapted to support one leg of a person, means rigidly interconnecting said pads, a ground engaging element below and associated with each pad, the improvement comprising means defining a bearing socket on the bottom of each pad, a generally sperical bearing in each socket, each bearing being rigidly connected to one of said ground engaging elements, each pad together with its socket being pivotable relative to their associated element through a limited arc to thereby facilitate tilting the pads as a unit and being rotatable relative to its associated element about a vertical axis, each said socket means being provided with a conical hole on the lower end thereof, each bearing being connected to its associated ground engaging element therebelow by a shaft extending through one of said holes, and a discrete elastomeric annular enclosure around each shaft and having one end removably coupled to the associated pad.
Claim 8
Dependent Claim
162 words
An amusement and/or an exercising device comprising first and second pads, each pad being adapted to support one leg of a person, means rigidly interconnecting said pads, a ground engaging element below and associated with each pad, the improvement comprising means defining a bearing socket on the bottom of each pad, a generally sperical bearing in each socket, each bearing being rigidly connected to one of said ground engaging elements, each pad together with its socket being pivotable relative to their associated element through a limited arc to thereby facilitate tilting the pads as a unit and being rotatable relative to its associated element about a vertical axis, each said socket means being provided with a conical hole on the lower end thereof, each bearing being connected to its associated ground engaging element therebelow by a shaft extending through one of said holes, and a discrete elastomeric annular enclosure around each shaft and having one end removably coupled to the associated pad.
Claim 9
Dependent Claim
163 words
An amusement and/or exercising device comprising first and second pads at opposite ends of the device, each pad being adapted to support one leg of a person, means extending between said pads and rigidly interconnecting said pads, a discrete ground engaging element below and associated with each pad, each ground engaging element being coupled to its associated pad by a joint, each joint including a generally spherical bearing in a mating socket so that each pad is pivotable about a horizontal axis through a limited arc relative to its associated ground engaging element to thereby facilitate tilting the pads as a unit so that one pad and its associated element is raised off ground level, each pad being rotatable relative to its associated ground engaging element about a vertical axis, the top surface of said pads being inclined inwardly toward each other, and a discrete elastomeric annular enclosure around each joint, each enclosure extending between each ground engaging element and its associated pad.
Claim 10
Dependent Claim
163 words
An amusement and/or exercising device comprising first and second pads at opposite ends of the device, each pad being adapted to support one leg of a person, means extending between said pads and rigidly interconnecting said pads, a discrete ground engaging element below and associated with each pad, each ground engaging element being coupled to its associated pad by a joint, each joint including a generally spherical bearing in a mating socket so that each pad is pivotable about a horizontal axis through a limited arc relative to its associated ground engaging element to thereby facilitate tilting the pads as a unit so that one pad and its associated element is raised off ground level, each pad being rotatable relative to its associated ground engaging element about a vertical axis, the top surface of said pads being inclined inwardly toward each other, and a discrete elastomeric annular enclosure around each joint, each enclosure extending between each ground engaging element and its associated pad.
