Description

[Detailed Description of the Invention] The present invention relates to an improvement of the L-shaped roof and opening/closing pivot of a fully-opening side freight vehicle, a so-called wing vehicle.

As shown in FIGS. 1 and 2, the pivot of the conventional wing vehicle is located on the loading platform floor (not shown) of the wing vehicle 1.
L-shaped roofs 6, 6 were attached via a plurality of hinges 5 to a support shaft 4 extending between the upper centers of a front wall 2 and a rear wall 3, which were erected at the front and rear ends of the roof. Therefore, the pivot 4
Although this wing has excellent rigidity, it is heavy, and as a result, the center of gravity of the wing vehicle 1 becomes high, which poses a problem in the stability of the vehicle. This had an inevitable effect on the loading capacity.

This idea was devised in view of the points mentioned above.
The object of the present invention is to provide a wing vehicle that eliminates the central support shaft, lowers the center of gravity of the wing vehicle, and increases the loading capacity.

The configuration for achieving this purpose is summarized as follows. In other words, it is a fully open side cargo vehicle in which a pair of L-shaped roofs are pivotally mounted between the front wall and the rear wall, which are erected in front and rear of the loading platform floor, and the L-shaped roof is connected to the front wall and the rear wall. It is supported by a single shaft supported at the upper center of the.

Examples will be described below.

Figure 3 shows a wing vehicle according to the present invention. The point that a pair of L-shaped roofs 6, 6 are supported by the front wall 2 and the rear wall 3 is the same as before. However, in the present invention, there is no supporting shaft that spans between the front wall and the rear wall as shown in FIG.

Details of the support portion of the L-shaped roof will be explained with reference to FIG. 4 and subsequent figures. Since the front and rear pivot parts are the same, the support part at the upper part of the rear wall will be explained below. Reference numeral 7 denotes a U-shaped frame that supports the pivot pin 8 and is fixed to the upper part of the rear wall. 9 is a side frame member of the L-shaped roof 6, and two brackets 10, 10 are attached to the side frame member 10 of the L-shaped roof 6.
It is fixed by welding etc. via a. Two of these brackets 10, 10 are attached to each L-shaped side frame member 9. As is clear from FIG. 4, the right roof brackets 10, 10 are mounted between the left roof brackets 10, 10. 11 is color. A sheet 12 covers the parts adjacent to the left and right L-shaped roofs 6, 6, and is fixed to the base of the L-shaped roof to prevent rainwater from entering from the ceiling.

Reference numeral 13 denotes a base frame member in the longitudinal direction of the L-shaped roof, which is made of hollow extruded material as shown in FIG.
It has a. Reference numeral 15 is a roofing material such as an aluminum plate, which is fixed to the side frame material 9, aggregate 14, etc. (FIG. 8).

As shown in FIG. 8, the side frame member 9 is provided with a hanging part 9a so as to cover the upper part of the rear wall 3, and is intended to be a perfect wall when it rains. As a matter of course, the sheet 12 extends to the upper part of the rear wall 3 so as to cover the pivot portion of the L-shaped roof as shown in FIG.

The above is the structure of the upper part of the rear wall, but as described above, the upper part of the front wall has the same structure.

As described above, according to the present invention, 1) the L-shaped roof is supported by a frame at the center of the upper part of the front and rear walls, and the L-shaped roof can be opened and closed, making it possible to reduce the weight of the upper structure of the wing vehicle. . Therefore, the center of gravity of the vehicle can be lowered. In other words, this means that the height of the vehicle can be made higher than in the past, increasing the cargo carrying capacity. 2) Also, since the L-shaped roof is supported only by the frame at the top center of the front and rear walls, when the L-shaped roof is opened, the height of the loading platform from the floor can be increased compared to before, making it easier to carry out cargo. It has become easier to enter.
