Description

[Detailed Description of the Invention] The present invention relates to a guide for inserting the operating handle of a spare tire carrier into the carrier shaft. Currently, spare tires for small trucks and the like are normally stored on a carrier fixed under a cross member at the rear of the chassis frame by a chain. By inserting the end of the crank-shaped handle into the hole of the shaft protruding rearward from the carrier and rotating it, the chain is wound up or unwound, and the chain is attached to the spare tire along with the tire fixing bracket at the lower end of the chain. It is designed to move up and down. To replace the spare tire, simply unwind the chain, lower the spare tire onto the road, and remove it from the tire fixing bracket.

The spare tire carrier's operating handle is a crank-shaped hand-cranked handle, but a single pin passes through its tip at right angles, and the carrier shaft into which it is inserted has a hole of the same shape, so the handle can be operated by hand. Once the tip of the handle is inserted, the carrier can be easily rotated. To do this, the tip of the operating handle must be inserted directly into the shaft hole through a hole in the rear bumper, but conventionally there was no guide in between and the handle was located in a location that was difficult to see.
It was difficult to insert them, and sometimes they had to cut a peephole in the rear bumper to make it look bad.

The present invention aims to eliminate the above-mentioned difficulties.
That is, after passing the tip of the operating handle through the hole in the rear bumper, a guide is provided so that once the handle is passed through the guide, there is no need to think about the direction, and the handle can be inserted into the carrier shaft by simply pushing it.

Examples will be described below with reference to the drawings. 1 is a chassis frame of a small truck, and a spare tire carrier 3 is installed in a cross member 2 at the rear end of the chassis frame.
is installed. Axle 4 rearward from carrier 3
is protruding from the hole, and when the tip of the crank handle 7 is inserted into the hole and rotated, the chain comes out and comes out, and the tire fixing device 5 at the tip of the chain moves up and down.
Reference numeral 6 denotes a rear bumper, and an elongated hole 9, which is sufficiently larger than the shape of the tip of the crank handle 7, is formed in its vertical surface. Further, a guide metal fitting 8 is fixed to the inside of the rear bumper 6. The guide fitting 8 is composed of a vertical plate part with a space between the front and back,
On the vertical plate part is the shaft 4 of the spare tire carrier 3.
Holes 10 and 11 corresponding to the shape of the tip of the crank handle 7 are formed on a straight line connecting the center of the elongated hole 9 formed in the rear bumper 6.

The attachment of the spare tire carrier 3 in the above configuration will be explained.

First, when the tip of the crank handle 7 passes through the long hole 9 of the rear bumper 6 and is inserted into the holes 10 and 11 of the vertical plate part of the guide fitting 8, both holes 10 and 11 are inserted.
The crank handle 7 is supported and the direction of insertion is regulated.

If the crank handle 7 is pushed further in this state, the tip of the crank handle 7 will be inserted into the hole in the shaft 4 of the carrier 3, so the crank handle 7 can be rotated to operate the carrier 3.

As described above, according to the present invention, the spare tire can be replaced easily and at the same time, time loss can be reduced. Furthermore, since the operating handle is supported by the guide metal fitting, the edges of the hole in the rear bumper are not rubbed, and rust can be prevented.
