Claim 3

A vehicle lift according to claim 1 wherein said upright further comprises a plurality of openings formed therein and a pin for insertion in the openings, whereby the carriage is restrained from inadvertently being lowered on the upright, and whereby the vehicle may be restrained in a predetermined rotated position.

Claim 4

A vehicle lift for lifting and rotating vehicles, comprising: (a) a frame for supporting the lift; (b) a plurality of wheels connected to the frame for allowing the lift to be moved easily; (c) an upright extending substantially vertically from the frame; (d) a y-shaped follower track mounted on the upright; (e) a carriage slidably connected to the upright; (f) a plurality of openings formed in the upright and a pin for insertion in the openings for restraining the carriage from being inadvertently lowered down the upright; (g) a collar mounted on the carriage; (h) a vehicle support rack rotatably connected to the collar, comprising: (i) a journal rotatably mounted in the collar; (ii) a sleeve mounted in the journal; (iii) a connector bar adjustably received in the sleeve for adjusting the vehicle support rack such that the center of gravity of the vehicle being lifted and rotated is substantially aligned with the journal and the collar, whereby the vehicle may be easily rotated and restrained from rotating; (iv) an extender bar mounted substantially normal to the connector bar; (v) a vehicle support bar mounted adjustably and substantially normal to the extender bar, for connection to the vehicle being lifted and rotated; (vi) at least one chain and corresponding tensioner adjustably mounted on the vehicle support bar for securing the vehicle support bar to the vehicle; (vii) a follower link mounted on the journal; and (viii) a follower rotatably mounted on the follower link for being received in the follower track and thereby controlling rotation of the vehicle; (i) a selector lever pivotally mounted in the divergence of the arms of the y-shaped follower track, to divert the follower into a preselected arm of the track and thereby cause the vehicle to rotate in a preselected direction; and (j) an actuating means connected to the carriage and to the frame for causing the carriage to slide up and down the upright and lift and rotate the vehicle.

Claim 5

A vehicle lift for lifting and rotating vehicles, comprising: (a) a frame for supporting the lift; (b) a plurality of wheels connected to the frame for allowing the lift to be moved easily; (c) an upright extending substantially vertically from the frame; (d) a y-shaped follower track mounted on the upright; (e) a carriage slidably connected to the upright; (f) a plurality of openings formed in the upright and a pin for insertion in the openings for restraining the carriage from being inadvertently lowered down the upright; (g) a collar mounted on the carriage; (h) a vehicle support rack rotatably connected to the collar, comprising: (i) a journal rotatably mounted in the collar; (ii) a sleeve mounted in the journal; (iii) a connector bar adjustably received in the sleeve for adjusting the vehicle support rack such that the center of gravity of the vehicle being lifted and rotated is substantially aligned with the journal and the collar, whereby the vehicle may be easily rotated and restrained from rotating; (iv) an extender bar mounted substantially normal to the connector bar; (v) a vehicle support bar mounted adjustably and substantially normal to the extender bar, for connection to the vehicle being lifted and rotated; (vi) at least one chain and corresponding tensioner adjustably mounted on the vehicle support bar for securing the vehicle support bar to the vehicle; (vii) a follower link mounted on the journal; and (viii) a follower rotatably mounted on the follower link for being received in the follower track and thereby controlling rotation of the vehicle; (i) a selector lever pivotally mounted in the divergence of the arms of the y-shaped follower track, to divert the follower into a preselected arm of the track and thereby cause the vehicle to rotate in a preselected direction; and (j) an actuating means connected to the carriage and to the frame for causing the carriage to slide up and down the upright and lift and rotate the vehicle.

Claim 6

A vehicle lift according to claim 3 wherein said carriage further comprises a plurality of carriage arms extending substantially vertically upward from the carriage and at least one cross-member connecting the carriage arms, and said actuating means is a hydraulic cylinder connected to the frame and the cross-member.

Claim 7

A vehicle lift according to claim 3 wherein said carriage further comprises a plurality of carriage arms extending substantially vertically upward from the carriage and at least one cross-member connecting the carriage arms, and said actuating means is a compressed air actuated cylinder connected to the frame and the cross-member.

Claim 8

A vehicle lift according to claim 3 wherein said actuating means comprises a jackscrew rotatably connected to the frame and threadably and rotatably connected to the carriage, and a power means to turn the jackscrew.

Claim 9

A vehicle lift according to claim 6 further comprising at least one limit switch connected to the upright to limit the travel of the carriage by deactivating said power means.

Claim 10

A vehicle lift for lifting and rotating vehicles comprising: (a) a frame means for supporting the lift; (b) an upright means extending substantially vertically from the frame means; (c) a carriage means slidably connected to the upright means; (d) a vehicle support rack means which is connected to the vehicle to be lifted, which is rotatably mounted to the carriage means, and which may be adjusted to substantially align the center of gravity of the vehicle being lifted and rotated with the point at which the vehicle support rack means is rotatably mounted to the carriage means; (e) a y-shaped follower track mounted on the upright means; (f) follower link means connected to the vehicle support rack means; (g) follower means mounted on the follower link means for being received in the y-shaped follower track and thereby controlling rotation of the vehicle; and (h) a selector lever pivotally mounted between the arms of the y-shaped follower track, to direct the follower into a preselected arm of the track and thereby control the direction of rotation of the vehicle.

Claim 11

A vehicle lift for lifting and rotating vehicles comprising: (a) a frame means for supporting the lift; (b) an upright means extending substantially vertically from the frame means; (c) a carriage means slidably connected to the upright means; (d) a vehicle support rack means which is connected to the vehicle to be lifted, which is rotatably mounted to the carriage means, and which may be adjusted to substantially align the center of gravity of the vehicle being lifted and rotated with the point at which the vehicle support rack means is rotatably mounted to the carriage means; (e) a y-shaped follower track mounted on the upright means; (f) follower link means connected to the vehicle support rack means; (g) follower means mounted on the follower link means for being received in the y-shaped follower track and thereby controlling rotation of the vehicle; and (h) a selector lever pivotally mounted between the arms of the y-shaped follower track, to direct the follower into a preselected arm of the track and thereby control the direction of rotation of the vehicle.
