Abstract
Two skate wheel devices each with a foot placement platform, a frame and a wheel. The wheel rotates relative to the frame. The user inserts both feet into respective platforms within the skate wheel devices while the devices rest on pavement. After shifting weight to one of the wheel skate devices, the other raised so that the foot is generally horizontal as opposed to pointing to the pavement. The wheel skate device with the raised foot is then rolled to the side. The user then raises the other wheel skate device so that its foot also points generally horizontally and rolls that wheel skate device in the same direction as the other to build momentum. The platform may rock back and forth relative to the wheel. Grooved rollers may be sandwiched between spaced apart frame elements.
Claims23
A wheel skate device, comprising:
- a unit that includes a frame;
- at least one wheel rotatable about a wheel axis within a plane of rotation;
- rotary couplings arranged to guide rotation of the at least one wheel about the wheel axis;
- and
- a foot placement platform supported by the frame to define a platform surface that is elongated in a direction substantially transverse to the plane of rotation of the wheel and extends clear of the wheel axis, the foot placement platform being arranged free of any constraint that would otherwise substantially prevent the foot placement platform from rocking back and forth about the wheel axis relative to the at least one wheel;
- wherein the foot placement platform is movable relative to the frame between a first in-use position and a second stowage position, the platform in the in-use position extending further from the plane of rotation than in the stowage position;
- and
- wherein in the stowage position, the platform is positioned substantially parallel to the plane of rotation.

A wheel skate device, comprising:
- a platform;
- a frame that encircles the platform during use;
- and
- a wheel supported by the frame that is rotatable about a wheel axis in a plane of rotation, the wheel encircling the foot of a user standing on the platform during use;
- wherein the platform is movable relative to the frame between a first in-use position and a second stowage position, the platform in the in-use position extending further from the plane of rotation than in the stowage position;
- and
- wherein the frame and platform are configured such that the frame and the platform in the stowage position define a gap substantially below the underside of a top portion of the frame and above the stowed platform that permits the ready insertion of a user's hand into that gap to hold the underside of the top portion of the frame to carry the device.

A wheel skate device, comprising:
- a platform;
- a frame that encircles the platform during use;
- and
- a wheel supported by the frame that is rotatable about a wheel axis in a plane of rotation, the wheel encircling the foot of a user standing on the platform during use;
- wherein the platform is movable relative to the frame between a first in-use position and a second stowage position, the platform in the in-use position extending further from the plane of rotation than in the stowage position;
- and
- wherein the outer lateral dimensions of the wheel and frame define an envelope, and the platform in the stowage position is positioned substantially within that envelope.

A wheel skate device, comprising:
- a platform;
- a frame that encircles the platform during use;
- a wheel supported by the frame that is rotatable about a wheel axis in a plane of rotation, the wheel encircling the foot of a user standing on the platform during use;
- and
- a plurality of rollers, some substantially under the platform and others not under the platform, positioned between the frame and wheel that support the rotatable movement of the wheel about the frame, the rollers substantially under the platform being arranged more densely than the rollers that are not substantially under the platform;
- wherein the platform is movable relative to the frame between a first in-use position and a second stowage position, the platform in the in-use position extending further from the plane of rotation than in the stowage position;
- and
- wherein the frame and platform are configured such that the frame and the platform in the stowage position define a gap substantially below the underside of a top portion of the frame and above the stowed platform that permits the ready insertion of a user's hand into that gap to hold the underside of the top portion of the frame to carry the device.

- wherein the platform is movable relative to the frame between a first in-use position and a second stowage position, the platform in the in-use position extending further from the plane of rotation than in the stowage position;
- and
- wherein in the in-use position, the platform extends substantially perpendicularly to the plane of rotation and, in the stowage position, the platform is positioned in a manner that is more parallel than perpendicular to the plane of rotation.
