Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hoisting spare tire carrier in which a spare tire is wound up by a chain and fixed to a body.

[0002]

2. Description of the Related Art As shown in FIG. 3, a spare tire carrier body 1 has a handle joint 9 and a chain 2.
A hook 4 is formed at the tip of the hook to engage with the hole 5a of the disk wheel 5 and is hooked over the hole 5a.
A hoisting spare tire carrier having a (suspension plate) and winding up the chain 2 by a gear mechanism to fix the spare tire to the body is well known.

[0003]

As shown in FIG. 4, the spare tire of the bus is stored by the spare tire carrier body 1 below the floor of the bus body 6 between the front and rear wheels. In this case, the chain 2 is hoisted and unwound by the handle 8, but the length of the chain 2 is the length of the position where the tire 7 touches the ground.

Therefore, in order to attach and detach the latch member 3 to and from the tire 7, the inspection port 10 on the floor surface is required while the tire 7 is grounded.
As shown in FIG. 5, the arm is extended and removed,
Using the handle 8, the tire 7, which is grounded directly below the floor of the bus body 6, is pulled out to the outside of the side of the bus body 6, and is pushed into the storage body just below the bus body 6. In this operation, the latch member 3 is connected to the inspection port 1 on the floor surface.
Extending the arm from zero and hanging it off worsened the workability.

It is an object of the present invention to provide a spare tire carrier which facilitates the work of attaching and detaching a latch member, and always allows a wound spare tire to be positioned in a fixed direction and stably stored.

[0006]

According to a first aspect of the present invention, there is provided a spare having a locking member at a leading end of a chain for engaging a hole of a disk wheel, and winding up the chain by a gear mechanism. In the tire carrier, the chain is long enough to allow the tire to move out of the body, bolts and nuts for tightening and fixing a disk wheel are provided on the retaining member, and the spare chain is stored in the spare tire carrier body. And a box-shaped guide member fitted into the hole of the disk wheel to be rolled up is fixedly provided.

Further, in the above configuration, the lower end of the guide member is tapered.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a spare tire carrier main body, which includes a handle joint 9;
A hoisting spare tire carrier having a retaining member 3 (suspension plate) that is hung over the hole 5a of the disc wheel 5 at the tip of the chain 2, and hoists the chain 2 by a gear mechanism to fix the spare tire to the body. is there.

According to the present invention, in the spare tire carrier described above, the chain 2 is elongated so that the tire 7 can move out of the bus body 6, and the pawl 4 engaging the hole 5 a of the disc wheel 5 And a bolt 11 and a nut 12 for tightening and fixing the disc wheel 5
Is provided.

Furthermore, the spare tire carrier body 1
Is fixedly provided with a box-shaped guide member 13 that fits into the half-moon-shaped hole 15 of the disk wheel 5 that stores and winds up the surplus chain 2. It is effective that the guide member 13 has a tapered shape at its lower end.

Since the present invention has the structure as described above, the unwound chain 2 is long, so that the tire 7 grounded directly below the floor of the bus body 6 uses a steering wheel as shown in FIG.
As shown by the arrow, the chain 2 is pulled out to the outside of the side of the bus body 6 with the chain 2 attached.

Therefore, the work of attaching and detaching the latch member 3 from the disk wheel 5 can be easily performed outside the side of the bus body 6.

In the case of the present invention, since the locking member 3 is provided with the bolt 11 and the nut 12 for tightening and fixing the disk wheel 5, the nut 12 is removed and the locking member 3 is inserted into the hole of the disk wheel 5. 5a. However, this operation is easy because it is performed outside the side of the bus body 6 as described above.

When the tire 7 is to be stored, the latch member 3 is connected to the hole 5 of the disc wheel 5 outside the side of the bus body 6.
Then, the nut 12 is screwed onto the bolt 11 and the disc wheel 5 is tightened and fixed.

The latching member 3 is connected to a disk wheel 5
After that, the tire 7 is pushed under the floor of the bus body 6 with the handle, the handle is connected to the joint 9 of the spare tire carrier body 1, and the chain 2 is wound up.

As a result, the tire 7 lifted to the lower surface of the floor of the bus body 6 has the semicircular hole 15 of the disc wheel 5 fitted into the guide member 13, and the tire 7 is guided by the guide member 13 in a horizontal posture. 6 is fixed to the lower surface of the floor in a stable state. If the lower end of the guide member 13 is tapered, the semi-lunar hole 15 of the disk wheel 5 can be fitted smoothly into the guide member 13.

Since the chain 2 is long enough to allow the tire 7 to move out of the bus body 6, when the tire 7 is wound up and the bottom surface of the bus body 6 is fixed to the floor, the chain 2 becomes slack and hangs down from the spare tire carrier body 1. The surplus portion of the chain 2 is automatically stored in the box-shaped guide member 13 to prevent a swinging movement or the like due to running.

[0018]

As described above, according to the present invention, the work for attaching and detaching the latch member can be performed outside the side of the bus body, so that the workability is facilitated and the wound spare tire is always positioned in a fixed direction. As a result, a stable storage state can be obtained because the guide member is guided and fixed. In addition, since the excess surplus of the long chain is stored in the guide member, there is an advantage that the chain is prevented from contacting with peripheral devices or the like due to the swinging motion of the chain.
