Abstract
Abstract A tire lift/carrier unit has a sheet metal housing forming an enclosure and having parallel spaced walls supporting a rotatable shaft which supports a rotatable spool formed by a set of sheet metal plates. A flexible cable has one end connected to the spool and its opposite end connected to a tire support member, and the plates are spaced closely together to define a track slightly wider than the cable so that the cable wraps on itself in a spiral overlapping manner. A ring gear is mounted on the spool and surrounds an internal drive gear supported for orbital movement by an eccentric cam member rotably supported by the shaft. The cam member is rotated by the shaft through a spring biased slip clutch mounted on the shaft.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
251 words
An improved tire lift/carrier unit adapted to provide an extended service life and to be mounted within a compact space, said unit comprising a drive shaft, a housing having spaced walls supporting said drive shaft for rotation, a set of annular plates forming a spool mounted on said drive shaft within said housing for rotation relative to said shaft and defining a narrow annular track, an elongated flexible cable having opposite end portions, means mounted on one of said end portions of said cable for supporting a tire, means connecting the opposite of said end portions of said cable to said spool, said annular track of said spool having a width only slightly greater than the diameter of said cable to confine said cable for wrapping radially outwardly on itself in a spiral overlapping manner within said track, an eccentric cam member mounted on said drive shaft for rotation relative to said drive shaft, clutch means connecting said drive shaft to said cam member and providing for driving said cam member with a predetermined limiting torque, an annular drive gear mounted on said cam member, means supporting said drive gear for orbital movement in response to rotation of said cam member, a ring gear surrounding said drive gear and having at least one tooth more than the number of teeth on said drive gear, and means rigidly connecting said ring gear to said spool to effect rotation of said spool in response to rotation of said shaft through said clutch means.
Claim 2
Dependent Claim
251 words
An improved tire lift/carrier unit adapted to provide an extended service life and to be mounted within a compact space, said unit comprising a drive shaft, a housing having spaced walls supporting said drive shaft for rotation, a set of annular plates forming a spool mounted on said drive shaft within said housing for rotation relative to said shaft and defining a narrow annular track, an elongated flexible cable having opposite end portions, means mounted on one of said end portions of said cable for supporting a tire, means connecting the opposite of said end portions of said cable to said spool, said annular track of said spool having a width only slightly greater than the diameter of said cable to confine said cable for wrapping radially outwardly on itself in a spiral overlapping manner within said track, an eccentric cam member mounted on said drive shaft for rotation relative to said drive shaft, clutch means connecting said drive shaft to said cam member and providing for driving said cam member with a predetermined limiting torque, an annular drive gear mounted on said cam member, means supporting said drive gear for orbital movement in response to rotation of said cam member, a ring gear surrounding said drive gear and having at least one tooth more than the number of teeth on said drive gear, and means rigidly connecting said ring gear to said spool to effect rotation of said spool in response to rotation of said shaft through said clutch means.
Claim 3
Dependent Claim
35 words
A tire lift/carrier unit as defined in claim 1 and including spacer means surrounding said shaft and disposed within said housing for limiting axial movement of said spool, cam member and gears within said housing.
Claim 4
Dependent Claim
30 words
