BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chain hook device for a truck loading gate.

[0002]

2. Description of the Related Art In a truck, a long object exceeding the length of a carrier may be loaded. At this time, general truck users often open the rear gate at the rear of the loading platform to load the cargo. However, since the lamps are provided at the lower part of the back of the loading platform, if the open rear gate is hung down to the rear of the loading platform, the lamps cannot be recognized. Of course, it is not legally allowed to load the luggage in such a manner as to obstruct the confirmation of lights such as a turn signal from behind.

Therefore, it is necessary to support the opened rear gate in a horizontal state. As a means for this purpose, the swinging end of the rear gate and the upper end of the rear end of the loading platform are suspended via a chain and a hook. (See Japanese Utility Model Publication No. 1-36701, Japanese Utility Model Application Laid-Open No. Sho 63-145774 and Japanese Utility Model Application Laid-Open No. Sho 63-149382).

[0004]

A chain-locking hook 1 provided on a track having a rear gate for such a purpose is mounted on a truck by protruding into the inside of a carrier as shown in FIGS. 6 and 7. Many were done.
However, in the case of such a hook 1, the space of the carrier becomes narrower by the amount of the protrusion, and the protrusion may interfere with the load during traveling, thereby damaging the load.

The present invention has been made in view of the above-mentioned conventional problems,
An object of the present invention is to solve the above-mentioned conventional problems by improving the shape of the hook member and the mounting structure thereof.

[0006]

SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a chain hook device for locking a chain for holding a rear gate pivotally openably and closably on a truck carrier in a substantially horizontal position, wherein the chain hook device includes a rear gate post. A hook member having a hook portion built in at one end, a plate portion for closing an open end portion of the upper rail, and a hole formed at the other end portion through the plate portion and through which a lock handle is inserted. The rear gate post is fixedly attached to the rear gate, and the rear gate post wall has an opening in which the hook portion faces outward.

[0007]

The function of the present invention is that the hook member does not protrude to the inner side of the carrier, the space of the carrier does not become narrower, the cargo does not interfere with the cargo, and there is no risk of damaging the cargo. Further, since the open end of the upper rail is closed by the plate portion of the hook member, the strength of the upper rail can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings. 1 and 2, a plate portion 6 having a hook portion 4 incorporated in a post 3 of a rear gate 2 pivotally attached to a truck carrier at one end and closing an open end of an upper rail 5, A hook member 9 having a hole 8 formed at the other end of the plate portion 6 and through which a lock handle 7 is inserted is provided.

The hook member 9 is bent at an intermediate portion in the opposite direction, and is fixed to the rear gate post 3 and the upper rail 5 by welding. Further, the hook portion 4 is formed in a shape that is bent in a substantially L shape from the lower side to the upper side.
An opening 10 is formed in the wall of the rear gate post 3 so that the hook 4 faces outward, and the chain 11 is engaged with the hook 4 through the opening 10.

A substantially U-shaped mounting member 12 is fixed to the inner surface of the plate portion 6 of the hook member 9 by welding. The mounting member 12 also has a hole 13 through which the lock handle 7 is inserted.
Is formed. The mounting end of the lock handle 7 is
The nut 15 inserted through the holes 8 and 13 of the mounting member 12 and the external thread 7A of the distal end thereof is inserted into an opening 14 formed in the upper rail 5.

According to such a configuration, the hook member 9 is disposed in the space inside the rear gate post 3 so as not to protrude toward the inner side of the carrier, so that the space of the carrier does not become narrower and does not interfere with the cargo. There is no danger of damaging the cargo. Further, since the plate portion 6 is integrally provided on the hook member 9 and the plate portion 6 is fixedly attached so as to close the open end of the upper rail 5, the upper rail 5 has a closed cross-sectional structure, and the strength of the upper rail 5 is improved. There is also an advantage that it can be achieved.

FIGS. 3 to 5 show another embodiment of the present invention. The hook member 16 of the embodiment of FIG. 3 has a pair of hook member structures 16A, 16A,
The buckle 16B is a walnut type welded and fixed with hooks 16a and 16b formed respectively. The open end of the upper rail 5 is closed by the plate 16c of one hook member structure 16B. The plate portions 16d and 16c of the hook member structures 16A and 16B are opposed to each other with a predetermined interval therebetween, and the lock handle 7 is inserted into the holes 16e and 16f formed respectively.

In the embodiment shown in FIG. 4, the hook portion 18 of the hook member 17 is formed in a substantially L-shaped shape from the lateral side to the lower side. A bent piece 19 is provided below the end of the hook portion 18, and the bent piece 19 is fixedly attached to the rear gate post 3 with a bolt 20 and a nut 21. In the embodiment shown in FIG. 5, the hook member 22 is formed of a substantially U-shaped member, a hook portion 23 is provided above the closed end of the substantially U-shaped member, and holes are provided at both end portions to which the lock handle 7 is inserted. 24 are provided.

In the case of this embodiment, the hook member 22 is fixedly attached to the rear gate post 3 and the upper rail 5 by an attachment such as an attachment screw 25. In each of these embodiments, the same operation and effect as those of the embodiment of FIGS. 1 and 2 can be obtained. It should be noted that the present invention is not limited to the configuration of the embodiment, and various changes can be made based on the claims of the utility model registration.

[0015]

As described above, the present invention has a hook portion built in the rear gate post at one end, a plate portion for closing the open end of the upper rail, and a through-hole formed in the plate portion. A hook member having a hole through which a lock handle is inserted and having a hook member at the other end is fixedly attached to the rear gate, and an opening is provided on the rear gate post wall so that the hook portion faces outward. In addition to the above, there is an advantage that the size of the upper rail can be increased, there is no risk of damage to the cargo, and the strength of the upper rail can be improved.
