Description

[Detailed explanation of the invention] Conventional open-top vehicles such as truck beds and trains have a smooth plate-shaped loading platform mounted and fixed on a vehicle body frame equipped with multiple wheels, and hinges are installed on three or four sides of the loading platform. The partition plate is attached to the platform so that it can be raised and lowered freely.When carrying cargo, the partition plate is rotated and suspended below the loading platform using a hinge as a fulcrum, and when traveling with cargo on it, the partition plate is installed to prevent the cargo from falling. Since the board is fixed in an upright position, the height of the loading platform is necessarily slightly higher than the diameter of the wheels, and the larger the vehicle, the higher the loading platform, so loading and unloading the cargo is extremely hard work. It was hot.

The present invention relates to an improvement of the partition plate of a cart so that even such a large vehicle can load and unload cargo with great ease.

The hinge B attached to the partition plate A of the conventional loading platform of a truck is such that the two strip plates C and D, located above and below, hold each half of the axis B, which is the fulcrum on which the partition plate A rotates and undulates. The upper band-shaped plate 2 is fixed to the partition plate A, and the lower band-shaped plate 2 is fixed to the rear end of the loading platform 6 using a normal hinge. It could only rotate 180 degrees or 180 degrees. In the present invention, among the strip plates 2 and 3 that support the shaft 5 from above and below, which is the fulcrum on which the partition plate 7 initially rotates, the upper strip plate 2 and the partition plate 7 are not fixed as in the conventional case. , is characterized in that it is equipped with a hinge-shaped opening/closing device A that fixes the band-shaped plate 1 that holds it via another shaft 4 to the partition plate 7 for the first time at a place as far as possible from the first fulcrum. It is.

That is, in the present invention, three strip plates 1, 2, and 3 are arranged in parallel, and shafts 4 and 5 are attached to the two joint points formed by arranging them in parallel.
, and the shaft 4 has strip plates 1 located above and below it,
2 to hold each half of the shaft 4 (for example, if band-like plate 1 holds both ends of shaft 4, band-like plate 2 holds the center of shaft 4, etc.), and adjust the length of shaft 4 appropriately. The shaft 5 is held in half by the band plates 2 and 3, respectively, so that the shaft 5 can be held in half by the band plates 1 and 3 respectively.
2 and 3 are respectively connected to form a triple hinge-shaped opening/closing device A. The strip plates 1 at both ends of this opening/closing tool A,
3 only needs to have enough vertical and horizontal sides to be fixed with screws, etc., but when the strip plate 2 is hung down, the height of the partition plate 7 depends on how high you want to fix the partition plate 7 from the ground. Just decide the length. In the opening/closing tool A formed in this way, the lower end strip 3 is fixed to the loading platform 6 with screws, the upper end strip 1 is fixed as far as possible to the upper part of the partition plate 7, and in the same way, the other opening/closing tool A is used to secure the partition plate 7. 7 and the loading platform 6 are fixed at several places, and the partition plate 7 is hinged so as to be able to rise and fall freely, and hooks 9 and 10 are provided protruding from the outside of the lower end and the inside of the upper end of both ends of the partition plate 7, respectively, facing each other. This relates to the structure of the partition plate of the cart. Since the present invention has the above-mentioned structure, the present invention will be explained with reference to the drawings of the embodiment.
As shown in FIG. 3, it is fixed to another partition plate or the like by a stopper (not shown) and stands upright.

Since the partition plate 7 becomes an obstacle when loading and unloading cargo, the partition plate 7 is folded down in the order shown in FIGS. 4 and 5.

That is, when the fasteners fixing the partition plate 7 are removed, the partition plate 7 descends while rotating to the right in FIG. 4 using the shaft 5 as a fulcrum. Up to this point, it is almost the same as a conventional partition plate, but the main difference is that the partition plate 7 now rotates around the shaft 4, and then rotates 180 degrees to form the partition plate 7. can also be made to hang perpendicular to the ground.

FIG. 5 shows a state in which the chain string 8 released from another partition plate or support is hooked onto the hook 9 after being rotated further 90 degrees from the state shown in FIG. Fig. 7 is a side view showing a state in which the conventional partition plate A is folded down and the chain string and _hook are hooked. is approximately the same as the height between the main partition plate 7 and the ground surface (GL), whereas the height _H2 between the main partition plate 7 and the ground surface (GL) is only the length L of the strip plate 2.
It is lower than H ₁ .

Therefore, when loading and unloading cargo onto a truck using the present invention, leave the partition plate 7 in the state shown in Fig. 5, and climb up the partition plate 7 and then the loading platform 6 from the ground in the order of steps, or vice versa. If you go down to the ground and load and unload the cargo, or if you stand on the partition board 7 and load and unload the cargo, there is no need to lift and unload the cargo a distance of H ₁ from the ground as in the conventional method. Therefore, even when handling the same amount of luggage, the degree of fatigue is greatly reduced.

In addition, as shown in Figure 7, in conventional carts, when the partition plate A is rotated 90 degrees, the chain string is hooked to the hook of the partition plate A to fix the partition plate A at the same angle, and the loading platform is moved to the partition plate. However, in this case as well, as shown by the dotted line in Figure 4, when the chain string 8 is rotated 90 degrees around the shaft 5 as a fulcrum, the chain string 8 is hooked onto the hook 10 provided opposite the hook 9. Like conventional ones, the loading platform can be used widely, making it extremely suitable as a partition plate for carts.
