Abstract
Abstract A current-collecting elastic tire for a vehicle in which a plurality of electrodes of conductive material are continuously or discontinuously embedded in the tire body in the circumferential direction of the tire tread portion, and these electrodes are exposed at one end thereof from the tire tread surface and connected electrically at the other end thereof to the vehicle by electrical wiring so that external electric current can be collected by the tire.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
146 words
A current-collecting and power transmitting elastic tire for a vehicle comprising a non-pneumatic tire made of elastomer and being of toroidal shape in radial section and including a tire body, a plurality of electrodes of conductive material embedded in the tire body and extending in the circumferential direction of the tire tread portion, said electrodes being exposed at one end thereof from the tire tread surface and being electrically connected at the other end thereof to electrical wiring extending to a radially inner portion of the tire for connection to a suitable portion of the vehicle, said electrodes being suitably grouped and adapted to be electrically connected to the vehicle by said electrical wiring so as to constitute at least two separate current transmitting circuits, each of which includes a flexible annular conductive band extending circumferentially of the tire and positioned in the tire tread portion.
Claim 2
Dependent Claim
146 words
A current-collecting and power transmitting elastic tire for a vehicle comprising a non-pneumatic tire made of elastomer and being of toroidal shape in radial section and including a tire body, a plurality of electrodes of conductive material embedded in the tire body and extending in the circumferential direction of the tire tread portion, said electrodes being exposed at one end thereof from the tire tread surface and being electrically connected at the other end thereof to electrical wiring extending to a radially inner portion of the tire for connection to a suitable portion of the vehicle, said electrodes being suitably grouped and adapted to be electrically connected to the vehicle by said electrical wiring so as to constitute at least two separate current transmitting circuits, each of which includes a flexible annular conductive band extending circumferentially of the tire and positioned in the tire tread portion.
Claim 3
Dependent Claim
115 words
A current-collecting and power transmitting elastic tire for a vehicle comprising a non-pneumatic tire made of elastomer and being of toroidal shape in radial section and including a tire body, a plurality of electrodes of conductive material embedded in the tire body and extending in the circumferential direction of the tire tread portion, said electrodes being exposed at one end thereof from the tire tread surface and being electrically connected at the other end thereof to electrical wiring extending to a radially inner portion of the tire for connection to a suitable portion of the vehicle, said electrical wiring being disposed to extend along the outer surface of the side walls of said tire body.
Claim 4
Dependent Claim
115 words
A current-collecting and power transmitting elastic tire for a vehicle comprising a non-pneumatic tire made of elastomer and being of toroidal shape in radial section and including a tire body, a plurality of electrodes of conductive material embedded in the tire body and extending in the circumferential direction of the tire tread portion, said electrodes being exposed at one end thereof from the tire tread surface and being electrically connected at the other end thereof to electrical wiring extending to a radially inner portion of the tire for connection to a suitable portion of the vehicle, said electrical wiring being disposed to extend along the outer surface of the side walls of said tire body.
