JACK ASSEMBLY ALTERNATE RETENTION OF TOW HOOK AND L-BOLT

The current design for the jack assembly (as shown in Figure 1) uses a foam packaging and nylon straps to secure the jack and two other separate parts: a tow hook, and an L-shaped bolt used for fastening a road wheel with a flat tire into the spare tire tub in the trunk of the vehicle while the spare tire is in use. This jack assembly rests flat underneath the spare tire bolted through the center hole in the lug wrench and foam packaging into a bracket on the tub floor. This foam packaging adds significant cost to the jack assembly, and blocks the user from being able to see the bolt as it fastens to the bracket on the tub floor.

Figure 2: Alternate Jack Assembly Design

The improved alternate jack assembly design (as shown in Figure 2) deletes this foam packaging from the assembly. A small bracket has been added to the load rest of the jack for the purpose keeping the load rest and the base of the jack even horizontally so the jack remains level when fastened underneath the spare tire (Figure 3). The retention of the tow hook and L-bolt is accomplished using a plastic clip which connects to the arm of the jack (Figure 4).

Conclusion

There are two significant improvements achieved by this new jack assembly design. First, the overall piece cost of the jack assembly is reduced due to the cost of the plastic c...
