Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates in general to a spare tire carrier. In particular, the invention is directed to a swing-away spare tire carrier for a motor vehicle.

2. Description of the Related Art

Swing-away spare tire carriers are commonly mounted on the rear of motor vehicles such as on sport utility vehicles. Many spare tire carriers are often after-market products, which an end user must order and install. Shipping costs for spare tire carriers can be expensive, as the spare tire carriers are large and heavy, particularly if a new after-market bumper is also ordered with the spare tire carrier. A typical, fully-assembled spare tire carrier may have a length of approximately that of a bumper of a motor vehicle, and may have a height roughly the size of a spare tire.

Many commercial package delivery companies base their shipping costs on a combination of weight and size of shipped packages, and may often impose higher shipping rates for larger or oversized packages. These shipping costs may be considerable and may increase the overall cost of purchasing an after-market spare tire carrier dramatically. Many consumers may base their decision to buy a particular spare tire carrier based on shipping price, and may even expect that the shipping costs are paid by the seller of the spare tire carrier.

Accordingly, there is a need for a spare tire carrier that is designed to minimize shipping costs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In one or more embodiments, a swing-away spare tire carrier assembly and system are designed to reduce shipping costs between the manufacturer and the end user, and between the manufacturer and its distributors. Shipping costs are often based on both the weight and the physical dimensions of a shipping container. Some shipping companies impose higher shipping rates for containers that are large or oversized.

Most conventional after-market spare tire carriers have swing-away arms mounted to the bumpers of vehicles with vertical members that connect the spare tires to the swing-away arms. Conventional after-market spare tire carriers may have horizontal dimension based on the lengths of the bumpers, and may have vertical dimensions based on the diameters of the spare tires. Conventional after-market spare tire carriers typically have a horizontal dimension of approximately 50 inches and a vertical dimension of approximately 24 inches. Hence, a shipping container for a conventional spare tire carrier may be approximately in excess of 50 inches by 24 inches.

In an embodiment, an after-market spare tire carrier assembly has two vertical pieces that connect the spare tire to the swing-away horizontal arm. The vertical pieces comprise a vertical support stub that is mounted to the swing-away horizontal arm, and a detachable center bracket that holds the spare tire and is bolted to the vertical support stub. The overall vertical height of the vertical support stub and the horizontal arm is approximately 10 inches, and the height of the center bracket is approximately 20 inches. As the center bracket is shipped detached from the vertical support stub, the shipping container for embodiments described herein are reduced compared to shipping containers for conventional spare tire carriers. In an embodiment, the shipping container holding a spare tire carrier assembly and a bumper has the dimensions of 50 inches length×15 inches height×8 inches width. Hence, shipping containers of embodiments described herein may have reduced vertical dimensions of 9 inches for a reduction of vertical height of approximately 37.5%.

FIG. 1 is a rear view of a motor vehicle 10 having embodiments of a spare tire carrier system 101′/201′/301′. As illustrated herein, reference will be made to three exemplary embodiments of spare tire carrier assemblies 101, 201, and 301, as well as to spare tire carrier systems 101′, 201′, and 301′. Embodiments of swing-away spare tire systems 101′, 201′, and 301′ each comprise a swing-away spare tire assembly 101, 201, 301 respectively with a bumper 110 described below. As used herein, a swing-away spare tire carrier assembly is labeled with the reference labels 101, 201, and 301 for embodiments of the swing-away tire carrier assembly having a vertical support stub referenced by labels 130, 230, and 330 (shown schematically in FIG. 1 as dashed lines) respectively as discussed below. It shall be understood, however, that the examples illustrated in the exemplary embodiments described below are non-limiting and other swing away spare tire carrier assemblies and systems are contemplated in one or more embodiments.

As illustrated, the motor vehicle 10 has a vehicle body 12 having a fold-down tail gate 14. The spare tire carrier assembly 101/201/301 is mounted on a bumper 110 having a pin 112 which is received by a cylindrical pivot housing 122 on the spare tire carrier assembly 101/201/301. The end opposite the cylindrical pivot housing 122 has a latching mechanism 123 which secures the spare tire carrier assembly 101/201/301 to the bumper 110. The spare tire 19 comprises a tire 18 mounted on a wheel 16 which has holes 17 for mounting the spare tire 19 onto an axle of a motor vehicle 10 or onto the spare tire carrier assembly 101/201/301.

Should a user wish to access the interior of the vehicle body 12, the user would disengage the latching mechanism 123, and swing the spare tire carrier assembly 101/201/301 away from the vehicle body 12 to allow the user to open the tail gate 14. When the user closes the tailgate 14, the user may then swing the tire carrier assembly 101/201/301 back toward the motor vehicle 10, and secure the tire carrier assembly 101/201/301 in place by re-engaging the latching mechanism 123.
