Description

APPARATUS FOR SPARE TIRE FOR AN AUTOMOBILE

The present invention relates to a spare tire detachment device for an automobile, and in more detail, the tire can be easily detached from the storage part of the trunk floor panel to easily and quickly fix the spare tire on the trunk floor panel. The present invention relates to a spare tire detachment device for a vehicle that can be detached and at the same time prevents an operator from being injured in the process of fixing and detaching the spare tire from the trunk floor panel.

Generally, when car is classified according to the shape of the car body, it mainly carries passenger cars with a small number of passengers, buses capable of carrying large numbers of passengers, trucks used to carry cargo, and large equipment or containers. Can be divided into trailers. Passenger cars have a fixed roof according to the form.Sedan has two rows of seats in front and rear, and two rows of seats and auxiliary seats in front and rear, allowing 6 to 8 passengers to ride the driver's and rear seats. Limousine divided by glass, convertible that can open and close the loop arbitrarily, and cargo wagon can be loaded in the cabin behind the rear seat to load cargo, and station wagon which is a combined passenger car equipped with rear door Station Wagon).

Among such passenger vehicles, in the case of a vehicle such as a station wagon, a separate spare tire carrier may be mounted on the outside of the rear door, and the spare tire may be fixed. However, in most passenger vehicles, a space part separately provided in the trunk floor panel is used. The spare tire is being loaded.

1 is an exploded perspective view showing a state in which the spare tire according to the prior art is fixed to the trunk floor panel, Figure 2 is an enlarged cross-sectional view of the main portion showing a state in which the spare tire according to the prior art is fixed to the trunk floor panel. 1 and 2, a storage unit 4 having a predetermined accommodation space is formed at one side of the trunk floor panel 2, and the storage unit 4 is moved from the bottom to the top. Increasingly, the inner side is formed to be inclined outward. The wing bolt 6 is fixed to the bottom surface of the storage part 4 of the trunk floor panel 2. A fastening nut 12 for securing the spare tire 8 to the wing bolt 6 is provided.

Briefly describing the state in which the spare tire is fixed to the housing of the trunk floor panel due to the coupling of the wing bolt and the fastening nut, first, the spare tire 8 corresponds to the upper end of the housing 4 of the trunk floor panel 2. The spare tire 8 is seated on the housing portion 4 of the trunk floor panel 2 in the state of being positioned. When the spare tire 8 is seated on the receiving portion 4 of the trunk floor panel 2, a guide having a wing bolt 6 fixed to the bottom surface of the receiving portion 4 formed at the center of the spare tire 8 is provided. It protrudes out of the spare tire 8 through the ball 10. When the wing bolt 6 protrudes to the outside of the spare tire 8 through the guide hole 10 of the spare tire 8, the spare tire 8 is driven into the trunk floor panel 2 using the fastening nut 12. ) In the housing (4). That is, the spare tire 8 is fixed to the receiving portion 4 of the trunk floor panel 2 due to the coupling of the wing bolt 6 and the fastening nut 12.

The spare tire could be fixed to the trunk floor panel using the above configuration, but in this case, it was very inconvenient to detach the spare tire from the storage of the trunk floor panel. That is, in order to detach the spare tire from the compartment of the trunk floor panel, it is very cumbersome for the operator to detach the spare tire from the trunk floor panel because the fastening nut must be released from the wing bolt by using a separate tool while bending the waist. It was. In addition, since the spare tire has to be moved to the upper part of the trunk floor panel while the worker is bent, the worker is often injured due to excessive force applied to the worker's waist during the operation. In particular, this problem was more serious for the elderly, including female drivers.

Accordingly, the present invention is designed to solve the above problems, the purpose is to configure the spare tire to be easily detached from the storage unit of the trunk floor panel fixed to the trunk floor panel easily and quickly And it can be detached and at the same time to provide a spare tire detachment device for a vehicle that can prevent the operator from being injured in the process of fixing and detaching the spare tire in the trunk floor panel.
