Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to improvements in spare tire carriers for automobiles, particularly trucks, light vans, etc., in which the spare tire is lifted up and supported by a chain or the like on the underside of the loading platform.

[Prior art]

Conventionally, a spare tire carrier attached to a truck or the like is equipped with an anchor plate that is rolled up by a hoisting device, and one of the two claws of this anchor plate is passed through a stud hole in the disc wheel of the spare tire, and
The other claw passes through the hole in the center of the disc wheel so that the spare tire can be hooked, but the two claws on the anchor plate can simply be hooked into the holes on the disc wheel side. Since the disc wheel of the spare tire is made of soft metal such as aluminum, it is easy to install it unstablely, which may cause the tire to fall when hoisting the spare tire.Furthermore, if the disc wheel of the spare tire is made of soft metal such as aluminum There was a problem in that the claws of the plate scratched the wheel surface.

[Purpose of invention]

This invention was made in view of the above-mentioned conventional problems, and it is possible to prevent the spare tire from falling off from the anchor plate of the spare tire carrier when the spare tire is rolled up, and
To provide a spare tire carrier capable of preventing damage to a wheel on the spare tire side caused by a claw part of an anchor plate.

[Structure of the idea]

This invention provides a spare tire carrier equipped with an anchor plate that is in contact with the lower surface of a disc wheel of a spare tire and that is pulled upward to support the spare tire from below. When the upper surface of the anchor plate contacts the lower surface of the disc wheel, at least two claws are fitted from below into the hole in the center of the disc wheel of the spare tire, and the outer periphery of the claw is pressed against the inner periphery of the hole. An engaging member made of a material such as rubber having a large coefficient of friction and high elasticity is provided and is attached to the claw portion so as to protrude so that the disc wheel of the spare tire is attached to the anchor plate. The above object is achieved by ensuring that the parts are fitted together stably and without being damaged.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, as shown in FIG. 1, a disc wheel 1 of a spare tire (whole illustration is omitted)
4. In the spare tire carrier 10, the anchor plate 18 is provided with an anchor plate 18 that is in contact with the lower surface of the spare tire and supports the spare tire from below by being hoisted upward by a hoist (not shown) via a chain 16. A claw portion 22 is formed on the upper surface of the anchor plate 18 and is fitted into the hole 20 at the center of the disk wheel 14 from below when the upper surface of the anchor plate 18 comes into contact with the lower surface of the disk wheel 14. An engaging member 24 made of a material such as rubber having a large coefficient of friction and high elasticity is provided, which protrudes so as to come into pressure contact with the inner periphery of the hole 20 and is attached to the claw portion 22. At least one pair of claw portions 22 of the anchor plate 18 is provided corresponding to the diameter of the hole 20 of the disk wheel 14, and the engaging member 24 is provided with small holes preformed in the at least one pair of claw portions 22. 26 is fitted. The disc wheel 14 of this engagement member 24
The portion facing the inner periphery of the hole 20, that is, the portion protruding from the outer periphery of the claw portion 22, is a substantially hemispherical head 24A, and the overall shape of the engaging member 24 is similar to a rivet. The amount of protrusion of the head 24A of the engaging member 24 is such that when the claw 22 is inserted into the hole 20 of the disc wheel 14 from below, a certain amount is formed in the gap between the outside of the claw 22 and the inner periphery of the hole 20. It is said to be compressed to the extent that it can be intervened. In this embodiment, when the spare tire is suspended and supported by the spare tire carrier 10,
The upper surface of the anchor plate 18 is the disk wheel 14
Insert the claw part 22 of the anchor plate 18 into the disc wheel 1 of the spare tire until it touches the lower surface.
4 into hole 20 from below. At this time, the claw portion 22 only needs to position the disc wheel 14 in the horizontal direction, and the fitting force may be small.
Since an unreasonable load is not applied to the disc wheel 14, and the engaging member 24 is attached to the claw part 22, the claw part 22 can be inserted into the hole 20 of the disc wheel 14.
When pushed into the hole 20, the head 24A of the engaging member 24 fits into the hole 20.
is elastically compressed between the inner periphery of the head 24A and the claw portion 22, and as a result, the anchor plate 18 and the disc wheel 14 are stably and reliably fitted together by friction welding of the head 24A, and horizontal positioning is achieved. I will do it. Furthermore, the anchor plate 18 supports the spare tire from below, and the upper surface of the anchor plate 18 is in contact with the lower surface of the disc wheel 14, so that
The disc wheel 14 is held in a horizontal position. Further, at this time, since the head 24A is made of a material such as rubber, it will not be damaged even if the disc wheel 14 is made of a soft metal such as aluminum. Therefore, the spare tire is prevented from falling off the anchor plate 18 and being damaged by relative movement before the chain 16 is hoisted up. In addition, especially in this embodiment, the engaging member 24 has a rivet shape, and the small hole 26 formed in the claw portion 22 is inserted into the engaging member 24.
It is installed by simply mating with the
It has the advantage that its structure is simple and there is almost no increase in cost. In the above embodiment, the anchor plate 18 is provided with a pair of claws 22, but the present invention is not limited to this, and the number of claws 22 may be at least one pair, or even three. good. Further, the engaging member 24 is a rivet-shaped member that is fitted into a small hole 26 formed in the claw portion 22, but this is because when the claw portion 22 is inserted into the hole 20,
Any material that can be elastically compressed between the outside of the claw portion 22 and the inner periphery of the hole 20 may be used. Therefore, for example, it may be attached to the claw portion 22 by inserting it into the claw portion 22 from above in the thickness direction. Further, in the above embodiment, the spare tire is hoisted up and supported by the chain 16, but the present invention is not limited to this. For example, the spare tire may be suspended and supported by bolts/nuts or wires. It may be.

[Effect of the idea]

Since the present invention is constructed as described above, the structure is simple, lightweight, and low cost. Before hoisting, the spare tire can be used as an anchor plate, stably, and the pawls can prevent the disk wheel from being forced. engages without being loaded or damaged;
The spare tire can be positioned horizontally, and the anchor plate supports the spare tire from below and holds it horizontally, so the spare tire can be held securely. This has an excellent effect of preventing the spare tire carrier from falling off the anchor plate of the spare tire carrier.
