Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal chain holding device for a rear body.

[0002]

2. Description of the Related Art In trucking, there is a case where a long object exceeding the length of a cargo bed, that is, a rear body is loaded. Opening the rear gate for loading is not permitted by law because the rear gate droops and lights cannot be confirmed. Therefore, as shown in FIG. 5, the free end of the rear gate 2 pivotally attached to the rear end of the rear body 1 and the lock plate 4 fixed to the upper end of the rear end of the side plate 3 standing on the side edge of the rear body 1. There is a rear body horizontal chain (hereinafter abbreviated as a chain) 5 laid between the two so as to keep the rear gate 2 horizontal and form the same plane as the surface of the rear body 1.

However, the above-mentioned conventional method has a problem that the rear body 1 vibrates during traveling and the chain 5 is disengaged from the lock plate 4. Japanese Utility Model Publication No. 60-44879 and Japanese Patent Application No. 5-2 by the present applicant.
Although the technology related to the rear gate is disclosed in 6988, it does not solve this problem.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a horizontal chain holding device for a rear body, in which the chain does not come off even when it is running and is detachable.

[0005]

According to the present invention, a lock plate fixed to the upper rear end of a side plate and having an upper protrusion extending upward has one end of a rear gate pivotally attached to the rear edge of the rear body. In a horizontal chain holding device for a rear body, which locks the other end of a chain locked to a free end, a lock protrusion extending rearward is provided on an upper protrusion, and a fixture is provided on the other end of the chain. A proximal end of the chain is pivotally attached to one longitudinal link at the other end of the chain, and a free end is engageable with the other link opposite the link and the fastener does not engage the link. A horizontal body for a rear body, characterized in that the other end of the chain can be freely inserted into and disengaged from the lock projection when in the open state, and the other end of the chain interferes with the lock projection when the fixture is in engagement with the link. Chi Over down the holding device.

[0006]

[Description of Operation and Effect] According to the horizontal chain holding device for a rear body configured as described above, when the other end of the chain is bridged below the lock protrusion provided on the upper protrusion, the fixing tool is used as a base end portion. Is rotated around the center to be in the open state and fitted into the upper protrusion, and when the fixing tool is then rotated to engage the link, the fixing tool interferes with the locking projection, so that the chain does not come off. Further, since the one end of the fixing tool is pivotally attached to the chain, the fixing tool does not get lost, and the engaging operation is easy because the fixing tool is engaged only by rotating the fixing tool.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a lock plate according to the present invention. The lock plate 40 is a rectangular plate body 45 as a whole.
On one side (the right side in the figure), the portion that remains when the concave portion 42 whose bottom portion has a circular arc is cut off is formed as a J-shaped upper protrusion 41, and the lower part of the upper protrusion is behind the vehicle (right side in the diagram).
A lock protrusion 43 extending in the direction of the arrow is projected. In this case, the lock protrusion 43 is formed so as to hang down diagonally downward. The projecting length L of the lock projection 43 is such that the chain end shown by the broken line can freely ride over the lock projection 43 when the fixing tool described later is in the open state, and when the fixing tool is in the engaging state. Is set to interfere with. A bolt hole 44 for fixing the plate body 45 to the upper rear end of a side plate (not shown) is formed.

FIG. 2 shows a chain end 51 according to the present invention. The chain end portion 51 is a chain end portion on the side that is stretched around the lock plate, and a fixture 52 is attached to the chain end portion 51. The fixture 52 is formed of a ribbon-shaped elastic plate such as spring steel, and the base end portion 52a is a chain end portion 5.
1 is rotatably wound around a link 51a on one side in the longitudinal direction (right side in the figure). The free end 52b is bent into a Z shape, and the link 5 on the other side (left side in the figure) of the chain end 51 is
It constitutes an engaging portion that is forcibly engaged with the inner surface of 1b. Therefore, it can be closed by engaging the link 52b with the link 51b as shown in FIG.

The operation will be described below with reference to FIG.

FIG. 4 shows a state in which the chain end 51 fits and inserts the upper protrusion 41 and the lock protrusion 43 so that the fixture 52 is engaged with the link 51b below the lock protrusion 43.
That is, according to the present invention, while the fixing tool 52 is released (released from the engagement state) from the chain end 51, the chain end 51 is fitted into the upper protrusion 41 of the lock plate 40, and the lock protrusion 43 is overcome. After the fixing 52
Can be rotated counterclockwise in the drawing to utilize the elasticity of the fixing tool 52 to force the free end 52b to be engaged inside the link 51b as shown in the drawing. The free end 52b can be forcibly disengaged and released from the inside of the link 51b by rotating in the clockwise direction in the figure, and the lock protrusion 43 can be overcome to disengage the chain end 51 from the upper protrusion 41.

[0012]

Since the present invention is constructed as described above, when the fixing tool is in engagement with the link, the fixing tool interferes with the lock projection, so that the chain will not come off. Further, since the one end of the fixing tool is pivotally attached to the chain, the fixing tool is not lost, and the work is extremely easy because the fixing tool is engaged with and disengaged from the link of the chain.
