Abstract

An improved cradle for a vehicle lifting device, comprising longitudinally spaced bearer elements at diametrically opposed portions of the rim of the vehicle wheel, is affixed to the vehicle wheel by attachment means having recesses or sockets to fit over the lug nuts, or sockets or hexrod bolts to fit over the wheel studs, of the vehicle wheel.

Claims

1. A cradle for a vehicle lifting device for rolling a vehicle over on its side and supporting said vehicle on its side in a raised position, comprising:

at least one bearer element, curved for at least a portion of its length, the convex surface of said curved portion being designed for rolling contact with a supporting surface; and

mounting means on the concave side of said bearer element for engaging a fully assembled vehicle wheel assembly and for securing said cradle to said vehicle without removing said wheel assembly from said vehicle;

said mounting means comprising a support bracket secured to and extending inwardly from said concave side of said bearer element, a vehicle wheel attachment plate located inwardly of said support bracket, means on said support bracket movably securing said wheel attachment plate thereto whereby said wheel attachment plate is free for orientation relative to means securing the vehicle wheel assembly to said vehicle, means engaged with said support bracket for locking said attachment plate in position, and a plurality of elongated connecting members each being secured at one end to said wheel attachment plate and, at the other end, engaging said vehicle wheel securing means of said wheel assembly.

2. A vehicle lift device comprising the cradle of claim 1 affixed to a front vehicle wheel assembly of said vehicle and a second such cradle affixed to a rear vehicle wheel assembly on the same side of said vehicle, whereby said vehicle can be rolled over on its side and supported on its side in a raised position.

3. A cradle according to claim 1, wherein said elongated connecting members are rods having threaded ends for engaging wheel assembly studs on said vehicle, each said rod including a portion of hexagonal cross-section.

4. A cradle according to claim 1, including receptacle means secured to at least one of said bearer elements, and a stabilizer bar for insertion in said receptacle means when said vehicle has been turned onto its side, thereby to prevent said cradle and vehicle from turning back onto its wheels.

5. A cradle for a vehicle lifting device for rolling a vehicle over on its side and supporting said vehicle on its side in a raised position, comprising:

at least one bearer element, curved for at least a portion of its length, the convex surface of said curved portion being designed for rolling contact with a supporting surface; and

mounting means on the concave side of said bearer element for engaging a fully assembled vehicle wheel assembly and for securing said cradle to said vehicle without removing said wheel assembly from said vehicle;

said mounting means comprising a support bracket secured to and extending inwardly from said concave side of said bearer element, a vehicle wheel attachment plate located inwardly of said support bracket, track means on said support bracket for movably securing said wheel attachment plate thereto whereby said wheel attachment plate is free for rotary and vertical orientation relative to means securing the vehicle wheel assembly to said vehicle, a pair of plate holding members mounted on said track means of said support bracket, one of said holding members being movable along said track member, means for clamping said wheel attachment plate between said holding members for locking said wheel attachment plate in position relative to said wheel assembly, and a plurality of elongated connecting members each being secured at one end to said attachment plate and, at the other end, engaging said vehicle wheel securing means of said wheel assembly.

6. A vehicle lift device comprising the cradle of claim 5 affixed to a front vehicle wheel assembly of said vehicle and a second such cradle affixed to a rear vehicle wheel assembly on the same side of said vehicle, whereby said vehicle can be rolled over on its side and supported on its side in a raised position.

7. A cradle according to claim 5, wherein each of said elongated connecting members is adapted for engagement with a wheel lug nut of said vehicle wheel assembly.

8. A cradle according to claim 5, wherein each of said elongated connecting members is adapted for engagement with a wheel assembly stud of said vehicle wheel assembly.

9. A cradle according to claim 7, wherein at least that portion of each said elongated connecting member in contact with said wheel lug nut is coated with a protective material.

10. A cradle according to claim 5, wherein said elongated connecting members are rods having threaded ends for engaging wheel assembly studs on said vehicle, each said rod including a portion of hexagonal cross-section.

11. A cradle according to claim 5, including receptacle means secured to at least one of said bearer elements, and a stabilizer bar for insertion in said receptacle means when said vehicle has been turned onto its side, thereby to prevent said cradle and vehicle from turning back onto its wheels.
