Abstract

The side plates of heavy trucks and trailers have long lengths, which are largely bent under vertical weight, causing the baggage to swell and collapse. In order to prevent this, it is good to divide the side plate into two or more, and install an intermediate pillar between them, but the opening and closing mechanism of the intermediate pillar itself is complicated, and it is necessary to attach the opening aid to each of the divided side plates, which increases the cost. I want to eliminate this drawback.

The side plate is divided into plural pieces, and the middle plate is installed between them, and the side plate is closed by supporting the rotation moment of the burrow by the weight of the side plate through the middle column and the stopper, etc. In this case, the hook provided on the stopper was engaged with the hook portion of the swinging arm installed on the vehicle body such as a truck.

In FIGS. 1 to 4 and 6, the pin 33 is fixed to the side plate 14 a of the bracket body 14 by a spring pin 39, and a boss installed at the other end of the rotating arm 10. 10a) is rotatably coupled to the pin 33 via the bush 40. In addition, one end of the handle 27 is rotatably coupled to the pin 33 via the bush 41.

At one end of the handle 27, a protruding portion 27a was formed, and at the other end, a lower joint was formed through a pin. A connecting rod 31 is installed between the lower joint 28 and the upper joint 29 (see FIG. 2).

A rocking arm bracket 26 is provided on one side of the bracket body 14, and the rocking arm 24 is installed in the center portion through the pin 25 on the bracket 26. The upper joint 29 is connected to one end of the swinging arm 24 via a pin, and a coil spring 30 is provided between the lower surface of the upper joint 29 and one side of the bracket 14. The other end of the swinging arm 24 is a hooked hook portion 24a. On the vehicle body side surface of the stopper 8, a hook 23 biting with the swinging arm hook portion 24a was formed. (See Figure 3)

The stroke adjusting device 32 is provided above the handle 27. 7 is a view showing details of the stroke adjusting device 32. As shown in FIG. In this figure, the nut 32b is fixed to the side plate 14a of the bracket body 14 by the bracket 32a, and the nut is screwed with the bolt 32c. A contact part 32d is provided in the front end of the bolt 32c, and the contact part 32d moves up and down and contacts the upper surface of the handle 27 by rotating the bolt 32c.

When the side plates 2a and 2b are closed, the hook 23 and the hook portion 24a are firmly engaged, so that the stopper 8 is vertically fixed to the side of the vehicle body such as a truck, so that the large bending caused by the longitudinal load of the side plate is achieved. You can stop it.

When opening the side plates 2a and 2b, the front arm 27a is first pulled forward (from Fig. 2 to left) and the swing arm 24 rotates clockwise in Fig. 2 against the force of the coil spring 30. The engagement of the 23 and the hook part 24a can open | release the side boards 2a and 2b.

When the jam is released and the jaw portion 27a is released, the swing arm 24 rotates counterclockwise in FIG. 2 by the force of the coil spring 30, but rotates counterclockwise by appropriately adjusting the stroke adjusting device 32. FIG. Stops on the way. To close the next open side plate 2a, 2b, the hook 23 pushes the swing arm hook 24a against the force of the spring 30 so that the side plate 2a, 2b is fully closed. ) And swing arm hook 24a are engaged.

8 is a view showing another embodiment of the present invention. In the above-described embodiment, the two side plates 2a and 2b are divided about the same length, and both side plates are fixed to the middle pillar, but in this other example, the lengths of the front and rear side plates are different, one side is short and the other is The side is long (the front side plate 2a is short in FIG. 8, and the rear side plate 2b is long, but vice versa). Moreover, both side plates 2a and 2b were detachably supported by the clasp 42 at the intermediate | middle pillar 4. As shown in FIG.

In this example, the middle column 4 may be opened and closed together with the long side plate 2b while the catch 42 of the short side plate 2a is hanging. The intermediate column 42 may open and close only the side plate 2a alone while standing. In this case, the side plate (2a) is short and light and can be easily opened and closed by the attraction. In this case, you can open and close only the side plate (2a) of the short side, such as when loading a small load, so you do not have to worry about the other parts collapse.

In the above-described two embodiments, the linking device for connecting the stopper 8 and the shaft 15 constituting the connecting member to transmit the stopper's motion to the shaft includes the rotary arm 10, the rod 12, and the lever 13. In this device, the lever is omitted by directly connecting the rotary arm and the shaft, or the rotary arm is omitted by directly connecting the lever and the stopper. In any of these cases, the present invention can be effectively implemented. .

In the above embodiment, the coil spring, which is an elastic member, is fixed to the vehicle body and positioned relative to a predetermined surface so that the shaft (connection member) penetrating the spring is maintained in a normal posture in a substantially horizontal direction. However, the predetermined surface may be rotatable around the intersection with the shaft, or a long hole may be inserted into the predetermined surface so that the angle of the shaft (and thus the spring) may change in response to the opening and closing movement of the stopper. . In this way, the structure of the linkage device can be simplified as described above. Therefore, the above-mentioned predetermined surface does not necessarily need to be a fixed surface.

In the above embodiment, the hook 23 on the stopper side and the hook portion 24a on the hook on the swing arm side are used to engage the stopper 8 and the swing arm 24. On the contrary, the hook portion on the stopper hook, swing You can also use a hook on the arm. In this case as well, this invention can be effectively implemented.

As the elastic member, not only a spring but also an air or hydraulic spring mechanism (air spring or hydraulic spring) may be used alone or in combination with the spring. In this case, a connection member can use a tubular thing other than a bar shape correspondingly.

The present invention makes it easy to open and close the side plate by manpower by supporting the rotational moment of the hinge by the opening auxiliary coil spring by the weight of the side plate, and it is fixed to the stopper connected to the middle column when opening the side plate. The following outstanding effects can be obtained by hooking the hook with the hook portion of the swinging arm installed on a vehicle body such as a truck. (1) By firmly locking the stopper mechanism, the warp caused by the longitudinal weight of the side plate of a very long carrier such as a truck or a trailer can be kept small. ② Therefore, it is possible to prevent the flank parts and collapse of the load. ③ The side plate can be easily opened and closed by manpower by the action of the elastic member that applies the stopper to the side plate closing direction. ④ When opening and closing the side plate, the stopper can be easily operated from the lower part of the stopper. ⑤ 4 or more effects can be realized at a very low cost.
