Description

DETAILED DESCRIPTION OF THE INVENTION (3-1) Field of Industrial Application The present invention relates to an intermediate plate for supporting a side swing plate of a carrier such as a large truck or a trailer, which is divided into a plurality. It relates to a support device.

(3-2) Prior Art There is a case where a side tilt plate of a carrier such as a large truck or a trailer is divided into two or three in a longitudinal direction of the carrier to facilitate handling. This is shown in FIG. 11 (front view) and FIG. 12 (enlarged exploded perspective view of the main part). That is, in both figures, a plurality of pairs (two pairs in the figure) of side tilt plates 3 are turned on the side surfaces of the long loading platform 2 of the truck 1 by hinges 4 around an axis parallel to the side edge of the loading platform. Mounted movably. A rectangular tubular support frame 5 is fixed to the carrier portion between the two side plates. A narrow portion 6A of a central pillar 6 integrally formed from a wide rectangular plate and a narrow rectangular plate is inserted into the support frame 5 and attached to the loading platform 2, and further wide. A stop plate 7 is attached to 6B, and a stop rod 8 attached to each side plate is connected to this stop plate, so that each side plate 3 is interposed between the center pillar 6 and the support frame 5. And is supported by the loading platform 2.

With such a structure, when unloading small luggage, it is possible to work easily by lowering only one side tilt plate, and when unloading large luggage, lower both side tilt plates, Furthermore, the work can be freely performed by removing the center pillar, which is extremely convenient. However, on the other hand, the following disadvantages were found in the conventional side tilt plate support system. In other words, if care is not taken to store the extracted pillar, it may be lost or placed underneath the wholesaled luggage, which may make it difficult to remove it. Furthermore, the part where the middle pillar is inserted into the support frame is exposed to the wind and rain, and dust enters, so it is easy to rust,
If you try to pull it out, it will not come out, or the support frame will protrude out of the loading platform, so it will be bumped and deformed when handling the load, or if the center pillar is deformed and you try to insert it, you will not be able to insert it Was often seen. Further, if the center column is made strong to prevent this deformation, there is a disadvantage that the center column becomes heavy and handling becomes difficult.

Conventionally, various proposals have been made as follows, for example, in order to solve the above-mentioned drawbacks of the method of supporting the side tilt plate of the truck.

1984 Utility Model Registration Application Publication No. 190680 “Truck Side Tilt Intermediate Supporting Device” 1982 Utility Model Registration Application Publication No. 165577 “Fan Intermediate Pillar” As a means for attaching the center column to the carrier, a method of inserting a rectangular plate, which is a part of the center column, into a rectangular cylindrical support frame is adopted. In addition, this center pillar, when opening all the side tilt plates,
The center pillar itself is bent by a hinge in the middle and hangs down below the side of the loading platform, so there is no need to remove it, and it is not lost as in the conventional example described above. However, in the presented example, it was impossible to prevent rusting and deformation of the insertion portion, which is one of the drawbacks of the conventional example described above.

Also, the adverse effects of this rusting and deformation can be prevented by providing a large gap in the insertion portion between the center pillar and the support frame. The disadvantage is that it cannot be performed.

As shown in the above, the center pillar is rotatably attached to the carrier by a pin, and if necessary, it is hung down the lower side of the carrier, so there is no need to remove it as above and there is no risk of loss. Absent. However, since the mounting of the center pillar to the carrier is performed by inserting a plate-like body attached to the center pillar to the conventional example or in the same manner as described above through a rectangular tubular support frame attached to the carrier, rusting or deformation may occur. The evils remained as they were.

(3-3) Problems to be Solved by the Invention The present invention provides a conventional support of a side tilt plate of a truck which is installed in the middle of a side tilt plate of a track divided into a plurality of pairs and supports the side tilt plate. This method eliminates the above-mentioned drawbacks of the method, is easy to operate, does not become unusable due to attachment or deformation, and has no play between the side plate of the truck and the back plate is secured to the carrier. It is intended to provide a support device.

(3-4) Means for Solving the Problems and Action Thereof The present invention relates to a side tilt plate of a truck which is installed in the middle of a side tilt plate of a track divided into a plurality of pairs and supports the side tilt plate. The problem described above is solved by configuring the intermediate support device from the following components (a) to (c).

(C) Truck carrier In this way, when the side tilt plate is fully opened, the tightening means between the middle pillar and the side tilt plate is released and the side tilt plates on both sides are suspended. Then, the tightening device between the carrier and the stopper is released, the stopper is suspended below the carrier, and the center pillar is suspended downward, so that the operation is simple.
Handles, springs, fixing brackets,
If a shrimp type lock composed of a hook or the like is used, there is no backlash, and therefore, the side tilt plate does not rattle. Further, as is clear from the embodiment described later, the engaging portion between the fixing member of the shrimp type lock and the hook is protected from the outside by the stopper, so that there is little danger of dust entering, and it is likely to be hit and deformed when handling the load. Nothing to do.

This shrimp lock has a method of providing only hooks on a carrier and providing other portions on a stopper, and a method of providing only hooks on a stopper and providing other portions on a carrier, and both can be effectively implemented in the present invention. It is sufficient to provide one shrimp lock between the center pillar and the loading platform. However, if two or more locks are provided, even if one of the locks fails, the stopper, middle pillar or side It is extremely safe without the risk of the tilting plate falling down.

In some cases, it is desired to provide an appropriate tightening means between the center pillar and the stopper. In this way, rattling of the side tilt plate can be more reliably prevented.

Trucks are usually equipped with side fenders under the carrier to prevent accidents.However, if a stopper or a center pillar is suspended below the carrier, these side fenders will hinder the vehicle and vertically hang below the carrier. It may not be possible. In the present invention, in the case of such a truck, a mechanism in which the stopper released from the tightening device can be rotated orthogonally to the side edge of the carrier and around a horizontal axis is simultaneously presented, and the side fender is provided. The side tilt plate can be fully opened without disturbing.
