DETAILED DESCRIPTION

Embodiments of the present invention provide a type of adjustable wheel rack in combination with a vehicle lift system to provide an easily adaptable and accessible station to store a wheel, facilitating vehicle maintenance work.

The wheel rack is described in detail with reference to FIGs. 1 through 6. The rack includes a locking frame plate 1, a stopper plate 13, a ball seat 2, a locking seat 22, and a rod 3.

The locking frame plate 1 may be formed, for example, by fastening together a first L-shaped plate 11 and a second L-shaped plate 12. A horizontal contact surface 11a of the first L-shaped plate 11 contacts a horizontal contact surface 12a of the second L-shaped plate 12 in forming the locking frame plate 1. Bolt holes 111 may be drilled along the length of the horizontal contact surface of the first L-shaped plate 11a. For example, FIGs. 1 and 2 show five rows of bolt holes 111 drilled into the horizontal contact surface 11a at intervals of 3", 3-1/2", 4", 4-1/2", and 5". Additional or fewer bolt holes 111 may be drilled into the horizontal contact surface 11a, and some embodiments may include continuous elongated slots instead of individual holes.

While reference is made herein to bolts 14a, 14b, 214 and bolt holes 111, 121, 121a, 131a, 213, openings drilled or formed into the first L-shaped plate 11, the second L-shaped plate 12, or the stopper plate 13 may be configured to accept any satisfactory fastening member, such as a screw, pin, et cetera.

Corresponding bolt holes 121a drilled into the horizontal contact surface 12a of the second L-shaped plate 12 allow bolts 14a to be inserted through the bolt holes 111 to secure the two plates 11, 12 together.

A stopper plate 13 may be provided to further support the locking frame plate 1 on a side column 41 of vehicle lift 4. At least one row of spaced bolt holes 121 drilled on the vertical contact surface 12b of the second L-shaped plate 12 correspond to at least one row of spaced bolt holes 131a drilled into the stopper plate 13. Bolts 14b, or any other acceptable fastener, may be inserted through bolt holes 121, 131a to secure the vertical contact surface of the stopper plate 13a to the second L-shaped plate 12.

When the first L-shaped plate 11, the second L-shaped plate 12, and the stopper plate 13 are secured together, the locking frame plate 1 is configured to hug the side column 41, as shown in FIG. 6. The locking frame plate 1 may be adjusted by varying the connections discussed above to meet a particular size of the side column 41.

A thru hole 112a in the horizontal contact surface 11a of the first L-shaped plate 11 and a thru hole 112b in the vertical contact surface 12b of the second L-shaped plate 12 (FIG. 4) correspond to holes 122, 132 in the second L-shaped plate 12 and the stopper plate 13, respectively. Bolts 14a may be inserted into the thru holes 112a, 112b and concave holes 122, 132 to contact the side column 41 for ensuring that the locking plate 1 does not slip relative to the side column 41.

A scale may be provided on the outside edge of the horizontal contact surface 11a of the first L-shaped plate 11 (as shown in FIGs. 1 and 2) and on the outside edge of the vertical contact surface 12b of the second L-shaped plate 12 (FIG. 4) to allow users to easily identify dimensions. When the user determines the dimensions of the side column 41, he or she may then adjust the first L-shaped plate 11 and the second L-shaped plate 12 accordingly, and secure the two plates 11, 12 together via the bolts 14a or other acceptable fasteners inserted through the bolt holes 111, 121a. The second L-shaped plate 12 and the stopper plate 13 may be similarly adjusted.

A ball seat 2 and locking seat 22 may be attached to a vertical contact surface 11b of the first L-shaped plate 11, providing a support system for the rod 3. The ball seat 2 may include a ball receiving plate 21 and a support block 23, as shown in FIG. 1.

A cavity 211 in the ball receiving plate 21 receives a sphere 31 on the end of the rod 3, and the locking seat 22 prevents the sphere 31 (and thus the rod 3) from undesirably detaching. In one embodiment, the diameter of the cavity 211 may be slightly smaller than the diameter of the sphere 31 on the end of the rod 3 such that the sphere 31 sits on the cavity 211 without falling through. Additionally, this may allow the sphere 31, and thus the rod 3, to rotate on the ball receiving plate 21.

In some embodiments, the locking seat 22 includes at least two stopper plates 221 secured to the vertical contact surface 11b of the first L-shaped plate 11. Each stopper plate 221 has a curved surface 2211 to prevent the rod 3 from separating from the ball receiving plate 21 while allowing the rod 3 to pivot vertically and horizontally.

With reference to FIGs. 4 and 5, the rod 3 may be rotated from a ready-for-use position 3a (e.g., a substantially horizontal position wherein the rod 3 is perpendicular to the vertical support surface 11b of the first L-shaped plate 11) to a substantially vertical position 3b when the rod 3 is not in use. Alternatively, the rod 3 may be horizontally to substantially parallel to positions 3c.

When in the ready-for-use position 3a, the rod 3 may be supported by a protruding block 212 located, for example, on an outside edge of the ball receiving plate 21. The protruding block 212 may include various recessed arcs 2121 providing several options for positioning the rod 3 and inhibits movement of the rod 3. As shown in FIG. 5, the rod 3 may be positioned on-center, or at various angles off-center as the recessed arcs 2121 allow.

As may be seen in FIG. 5, the support blocks 23 positioned beneath the ball receiving plate 21 may be provided to further support the ball receiving plate 21 and the rod 3.

The ball receiving plate 21 may be secured to the vertical contact surface 11b of the first L-shaped plate 11 using any acceptable fastening means (e.g., welding, bolts, etc.). Holes 213 in the ball receiving plate 21 may be matched up with holes 213a drilled in the vertical contact surface 11b of the first L-shaped plate 11 to ensure correct placement of the ball receiving plate 21. Bolts 214 may be inserted into the holes 213 to secure the ball receiving plate 21 to the vertical contact surface 11b of the first L-shaped plate 11. Alternative means of securing the ball receiving plate 21 to the first L-shaped plate 11b (for example, welding or chemical bonding) may also be used.

The rod 3 may be cylindrical as shown in FIGs. 1-6. Alternatively, the rod 3 may be rectangular, hexagonal, or octagonal, for example. A stopper 32 may be provided at an opposite end of the rod 3 from the sphere 31 to prevent a wheel 5 from sliding off of the rod 3.

An example of the locking frame plate 1 in use with a vehicle lift 4 is shown in FIG. 3. A side column 41 provides support for a vehicle when the vehicle lift 4 is extended. The locking frame plate 1 may be positioned near the ends of the side column 41 as shown in FIG. 4. However, the locking frame plate 1 may be positioned anywhere on the side column 41 as is convenient for providing maintenance to the vehicle.

The wheel 5 may be positioned on the rod 3 (FIG. 6) while maintenance is being performed on the vehicle. The stopper 32 prevents the wheel 5 from slipping off the end of the rod 3. When maintenance on the vehicle is complete, the wheel 5 is removed from the rod 3, and secured to the vehicle.
