Abstract

The jack stand assembly includes a coupling plate with a plurality of openings for receiving the lugs of a wheel hub to fixedly attach the coupling plate with the wheel hub. The coupling plate is operably supported by a support structure which has an adjustable height. The support structure is configured to rotate about a vertical axis to allow the wheel hub to be rotated in a steering motion when the wheel hub is fixedly attached with the coupling plate. A bearing assembly is interposed between the coupling plate and the support structure to allow the wheel hub to rotate about a horizontal axis.

First claim

What is claimed is:

1. A jack stand assembly for a vehicle comprising:
a coupling plate with a plurality of openings for receiving lugs of a wheel hub to fixedly attach said coupling plate with the wheel hub;
a support structure operably supports said coupling plate, said support structure having a vertical height which is adjustable, and said support structure being configured to rotate about a vertical axis to allow the wheel hub to be rotated in a steering motion when the wheel hub is fixedly attached with said coupling plate; and
a bearing operably interposed between said coupling plate and the support structure for allowing the wheel hub to rotate about a horizontal axis;
wherein said support structure includes a bearing housing with a post that is threadedly engaged with another component of said support structure, and wherein said bearing housing has a through opening, and wherein said bearing is disposed in said through opening; and
wherein said coupling plate has a projection which extends through said through opening of said bearing housing.

2. The jack stand assembly as set forth in claim 1 wherein said support structure includes at least two pieces that are threadedly connected with one another to allow adjustment of said vertical height of said support structure by threading one of said pieces into or out of the other of said pieces.

3. The jack stand assembly as set forth in claim 1 wherein said support structure includes a turnplate with a fixed platform and a movable platform that is able to move with low friction on said fixed platform.

4. The jack stand assembly as set forth in claim 1 wherein, when said coupling plate is fixedly attached with the wheel hub, said vertical axis that said support structure is rotatable about is generally aligned with a pair of ball joints that support the wheel hub on the vehicle.

5. A jack stand assembly for a vehicle comprising:
a coupling plate with a plurality of opening for receiving lugs of a wheel hub to fixedly attach said coupling plate with the wheel hub;
a support structure operably supporting said coupling plate, said support structure having a vertical height which is adjustable, and said support structure being configured to rotate about a vertical axis to allow the wheel hub to be rotated in a steering motion when the wheel hub is fixedly attached with said coupling plate; and
a bearing operably interposed between said coupling plate and the support structure for allowing the wheel hub to rotate about a horizontal axis;
wherein said support structure includes a bearing housing with a post that is threadedly engaged with another component of said support structure, and wherein said bearing housing has a through opening, and wherein said bearing is disposed in said through opening;
wherein said support structure includes a turnplate with a fixed platform and a movable platform that is able to move with low friction on said fixed platform;
wherein said support structure includes a support which is fixedly attached with said movable platform of said turnplate;
wherein said support structure further includes a vertical arm which is fixedly attached with said support and extends in a vertical direction upwardly therefrom; and
wherein said support structure further includes a horizontal arm which is attached with said vertical arm and which has an opening that is threadedly engaged with said post of said bearing housing.
