Abstract
Abstract A spare wheel for automobiles which removably attaches to the wheel of a flat tire and permits movement of the vehicle without fixing or removing the tire. The spare wheel comprises a pair of rigid wheel segments of unequal size which are pivotally connected and together form a wheel having a diameter at least as great as the tire. The smaller segment pivots outwardly to permit attachment of the unit to the wheel of the flat tire, after which the vehicle is advanced until the segments can be returned to the wheel forming position. The edge of the first segment which is common with the second segment is arcuately shaped to permit it to roll in either direction notwithstanding composition of the road surface.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
202 words
A spare wheel for a vehicle supported by pneumatic tires mounted on rigid wheels, comprising: a first rigid wheel segment having a partial road engaging wheel surface and a segmented surface; a second rigid wheel segment having a partial road engaging wheel surface and cooperable with the first wheel segment to form a vehicle supporting wheel having an essentially complete wheel surface; means for connecting the first and second wheel segments in hinging relation to permit the second wheel segment to be rotated out of the plane of the first wheel segment; means for releasably fastening the first wheel segment to one of said vehicle wheels, comprising a plurality of elongated fastening members, each fastening member having first and second ends and being pivotally connected intermediate said end to the first wheel segment to permit radial outward movement of the first end into engagement with the inner face of a vehicle wheel; and actuating means for rotating each fastening member to effect engagement of the first end thereof with the vehicle wheel; the segmented surface being arcuately shaped to permit said vehicle to roll thereon; and means for releasably holding the second wheel segment in the plane of the first wheel segment.
