Description

[Detailed description of the invention] The present invention relates to a spare tire support device for a motor vehicle.

Conventionally, in some automobiles such as trucks, a drum is attached to the underside of the vehicle body and a hanging member is wrapped around it, and a spare tire is hung from the hanging member. Because the worker descends straight down from the position where it is rolled up on the lower member, the worker must crawl under the vehicle body when removing the spare tire from the hanging member, and the worker must also hang the spare tire from the hanging member and then roll it up. In this case as well, the work must be done below the vehicle body, and there is a problem in that it is difficult to install and remove the spare tire.

In view of this, the present invention has provided that one end of a connecting member is attached to a sliding member that slides in an inclined groove that is provided on the lower surface of the vehicle body on the outer edge side of the vehicle body relative to the spare tire rolling-up position and is inclined downwardly toward the outside of the vehicle body. A spare tire support device that allows the spare tire to be lowered from a rolled-up position to the outer edge of the vehicle body, and vice versa, by engaging the other end with a hanging member. The aim is to provide a solution to existing problems.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below based on embodiments with reference to the drawings.

Reference numeral 1b denotes a spare tire support device for an automobile, in which a hoisting means 5 is attached to a frame 3 on the rear lower surface of the car body floor 2, a hanging member 6 is wound around the hoisting means 5, and the hanging member 6 A spare tire 7 is suspended, and the frame 3 on the outer edge side of the vehicle body from the tire rolling-up position and the hanging member 6 are connected by a connecting member 22.

The hoisting means 5 consists of a drum 10 and a drum case 11. The drum 10 is provided with a protrusion 12 on the outer periphery of the center as shown in FIG. A locking portion 13a is provided at one end of the support shaft 13, and the drum 10 is rotated by engaging the handle 14 with the locking portion 13a.

The hanging member 6 is a chain, one end is connected to the drum case 11, and the part wrapped around the drum 10 is connected to the protrusion 1.
2, a locking portion 15 is attached to the other end, and a stopper 16 is fixed at a position close to the locking tool 15.

The connecting member 22 is an elongated rod, and one end is slidably attached to the inclined groove 21 of the bracket 20 attached to the frame 3, and the other end is bent into a hook shape and is connected to the stopper 16 of the hanging member 6. It is loosely fitted between the locking tool 15.

The bracket 20 has a front end fixed to the drum case 11 and a rear end fixed to the rear cross member 18, and has a separate inclined groove 21 inclined downwardly toward the outside of the vehicle body. The roller 2 is slidably engaged with the roller 2.
One end of a connecting member 22 is pivotally attached to 3.

In the diagram, 17 is the rear door, 18 is the rear cross member, and 19 is the rear door.
is a stop member that stops the spare tire 7 at the rolled-up position and prevents the tire from swinging during driving.

In the spare tire support device 1b, when the drum 10 is rotated by the handle 14 from the spare tire hoisting state shown in FIG.
6 corresponds to the connecting member 22, and the spare tire 7 corresponds to the hanging member 6.
The lower part of the stopper 16 is suspended vertically downward, and as the connecting member 22 rotates and the roller 23 slides in the inclined groove 21, it moves toward the outer edge of the vehicle body and descends. As shown in Figure 2, the vehicle descends to the ground 24 below the outer edge of the vehicle.

Conversely, when hoisting the spare tire 7, the spare tire 7 is attached to the hanging member 6 at the position shown in FIG. 2, and when the drum 10 is rotated, the spare tire 7 is moved to the hoisting position shown in FIG. be lifted up.

Incidentally, a large load is applied to the drum case 11 in order to support the spare tire 7, but in this example, the bracket 20
Since the front end of the drum case 11 is firmly fixed to the drum case 11 for reinforcement, the drum case 11 has excellent durability.

Therefore, when installing and removing the spare tire 7,
Workers do not have to crawl under the vehicle body, making the work easier.

Note that as the connecting member 22, a wire may be used instead of a rond.

As described above, according to the present invention, the spare tire can be lowered from the rolled-up position to the outer edge of the vehicle body, and conversely, it can be rolled up from the outer edge of the vehicle body to the rolled-up position. The operator does not have to crawl under the vehicle body during removal, which has the advantage of making the work easier.
