Description

[Detailed Description of the Invention] This invention relates to a spare tire carrier for an automobile.

In general, a spare tire carrier for a car has one end of a tire hanger pivotally attached to the underside of the car body, the spare tire being sandwiched between the tire hanger and the car body, and the other end of the tire hanger being locked to the car body. , the spare tire is stored under the vehicle body. In such spare tire carriers, the vehicle body often has a high ground clearance, so when storing the tire, the tire hanger has a large slope, making it difficult to store the tire, and the tire hanger has a large slope. In some cases, the tire hanger is heavy, so when lowering it, there is a problem in that the operator's fingers may get caught between the tire hanger and the ground. In order to eliminate such problems, it is necessary to
As stated in No. 91160, it is possible to make the tire storage part of the tire hanger deeper so that the bottom surface of this storage part touches the ground, creating a gap between the handle of the hanger and the ground. However, there is a problem in that it becomes difficult to take out the tire from the hanger. Another option is to fix a stand to the handle of the tire hanger and leave a space between the handle and the ground to prevent the worker's fingers from getting caught, but this If the rear tire blows out while the vehicle is loaded with luggage, the ground clearance of the rear bumper becomes low, and this bumper gets in the way, making it difficult to take out the spare tire, and when the tire is stowed. There was a problem that a protrusion was visible on the lower side of the bumper, which was undesirable in terms of appearance.

In view of such conventional problems, the present invention provides a rotatable hook on the tire hanger for locking the tire hanger to the vehicle body, so that this hook can also be used as a stand.
To provide a spare tire carrier for a motor vehicle, which allows the tire to be easily replaced even when the rear tire becomes punctured when a large amount of luggage is loaded, and which also improves the appearance.

An embodiment of the present invention will be described in detail below with reference to the drawings.

1 to 4 show a spare tire carrier for an automobile according to an embodiment of the present invention. A tire hanger 3 for storing a spare tire 2 is provided at the rear lower side of the vehicle body floor 1 of the automobile. It has a rear end rod portion 3b. Both ends of the tire hanger 3 are rotatably connected to a bracket 4 fixed to the underside of the vehicle floor 1, and a frame 5 is fixed to the center of the tire hanger 3 in the vehicle width direction. In order to prevent the spare tire 2 from escaping in the vehicle width direction, both ends 5a thereof are bent upward. Further, a cross member 6 is fixed to the lower surface of the vehicle body floor 1, and a spare tire 2 is fixed by being sandwiched between the cross member 6 and the tire hanger 3. Furthermore, a clamp bolt 7 as a locking member is attached to the rear end of the vehicle body floor 1 so as to be rotatable in the vehicle width direction, and a rear bumper 10 is provided on the rear side of the vehicle body floor 1.

A plate-shaped hook 8 is rotatably attached to approximately the center of the rear end rod portion 3b of the tire hanger 3 by wrapping its rear end around the rear end rod portion 3b, and a projection 8b is attached to the center of the attachment portion 8a. It is formed by cutting it up. A notch 8c is formed from the side edge of the hook 8, and the tip of the hook 8 is bent downward. Further, the rear end rod portion 3b of the tire hanger 3 has mounting portions 8a on both sides of the hook 8.
A stopper 9 is welded and fixed between the hooks 8 and 9, and the stoppers 9 move the hooks 8 to the horizontal position A shown in solid lines in FIG.
and a downwardly hanging stand position B shown by a dashed line in the figure.

Next, a method of using the spare tire carrier of this embodiment will be explained.

When a spare tire is stored in this carrier, the tire hanger 3 is locked to the vehicle body floor 1 by engagement with the clamp bolt 7 and the hook 8, and the tire hanger 3 and the cross member on the underside of the vehicle body floor 1 are connected to each other. A spare tire 2 is sandwiched between the tire 6 and the tire 6. In addition, the shaft portion 7 of the clamp bolt 7 is located in the notch 8c of the hook 8 at the rear end of the tire hanger 3.
b is inserted, and the hook 8 is held in the horizontal position A by being held between the back surface of the head 7a of the clamp bolt 7 and the first contact surface 9a of the stopper 9. In this way, the clamp bolt 7 and the hook 8 are engaged.

When the traveling tire is flat and needs to be replaced, first loosen the clamp bolt 7 by turning its head 7a from the above-mentioned stored state, and then
When the hook 8 is rotated in the vehicle width direction and disengaged from the hook 8, the hook 8 rotates from the horizontal position A in the direction of the arrow C and hangs downward due to its own weight. In this state, when the rear end rod portion 3b of the tire hanger 3 is held in hand and the tire hanger 3 is lowered in the direction of arrow D, the lower end of the hook 8 comes into contact with the ground 11. When the tire hanger 3 is further lowered in the direction of arrow D, the hook 8 further rotates in the direction of arrow C, the protrusion 8b of the hook 8 comes into contact with the second contact surface 9b of the stopper 9, and the hook 8 It is held at stand position B. Therefore, after the tire hanger 3 is held in the inclined state shown by the dashed line in FIG. 1, the spare tire 2 may be taken out from the tire hanger 3. Then, place the flat running tire on the inclined tire hanger 3, hold the rear end rod 3b of the tire hanger 3, and lift it upward, and the tire hanger 3 will rise upward. Then, the flat tire comes into contact with the cross member 6 on the lower surface of the vehicle floor 1. Therefore, by rotating the hook 8 hanging down in this state in the opposite direction to the C direction to engage the clamp bolt 7, and tightening the bolt 7, the flat tire can be moved between the tire hanger 3 and the vehicle body floor 1. In this way, tires can be replaced.

In addition, if the rear tire becomes flat when a lot of luggage is loaded, the ground clearance of the rear bumper 10 will be lowered, so if you try to take out the spare tire 2 using the hook 8 as a stand as described above, , the rear bumper 10 may get in the way, making it difficult to take out the spare tire 2. However, with this carrier, in such a case, by tilting down the hook 8 and placing the tire hanger 3 in the steep slope shown by the two-dot chain line in FIG. 1, a sufficient distance can be created between the rear bumper 10 and the tire hanger 3. This allows the spare tire 2 to be easily taken out.

In the spare tire carrier of this embodiment as described above, the hook can normally be used as a stand, so the worker's fingers will not be caught between the tire hanger and the ground when the tire hanger is lowered. It can be easily placed on a tire hanger, and furthermore, the tire hanger can be easily grasped when lifting the tire hanger, resulting in good workability.

In addition, the hook is rotatably installed on the tire hanger, so if the rear tire goes flat and the vehicle's ground clearance becomes low when a large amount of cargo is loaded, the hook can be tilted forward to easily connect the vehicle and the tire. Adequate spacing between hangers allows tires to be easily replaced.

Furthermore, in this device, the hook is held in a horizontal position when the tire is stored, and does not protrude below the bumper, so it is favorable in terms of appearance.

Furthermore, since the hook for securing the tire hanger to the vehicle body is used as a stand, there is no need to provide a separate stand, the structure is very simple, and the cost does not increase.

Note that the present invention is not limited to the above-mentioned embodiments, and can be modified in various ways. For example, the stopper may be formed integrally with the tire hanger instead of being welded to the tire hanger. be.

As described above, according to the spare tire carrier for a car according to the present invention, the hook for locking the tire hanger to the vehicle body is rotatably provided on the tire hanger, so when the tire hanger is lowered, Normally, the hook can be used as a stand, which improves safety and workability.Also, if the rear tire goes flat when loading cargo and the vehicle's ground clearance becomes low, by tilting the hook forward, the vehicle body and tire Adequate spacing is provided between the hangers, tires can be easily replaced, and the appearance is also favorable.
