Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a storage device for a walk board which is installed between a luggage box and the ground and is used when unloading vehicles and the like.

(Prior Art) Conventionally, as a storage device for a step board, as seen in the one described in Japanese Utility Model Laid-Open No. 61-150233, storage parts are provided on the outer surfaces of the left and right side plates of the packing box. There is provided an apparatus configured to store a pair of walking boards, respectively.

(Problems to be solved by the invention) However, in the above-mentioned conventional one, at the time of storage,
There is a problem that the walk board is exposed to the outside from both sides of the packing box to impair the aesthetic appearance, and foreign matter is easily mixed in the storage section.

In addition, since the step boards are stored one by one on the left and right side plates, two storage portions are required, and it takes time to put them in and out.

On the other hand, as disclosed in Japanese Patent Laid-Open No. 58-164448, there is also one in which a pair of walking boards are stacked and stored inside the rear door, but this pair of walking boards is simply two sheets. Since the thickness when stored is equal to the thickness of the two walking boards by simply combining them, in order to store this pair of walking boards in the rear door, the storage space in the rear door must be increased. As a result, there is a problem that the thickness of the rear door is increased.

(Means for Solving the Problems) In a storage device for a step board according to the present invention, a rear door is provided at a rear portion of a luggage box provided on a vehicle frame so as to be openable and closable, and a pair of step plates is provided in the rear door. Is formed so that the front surface of the walking board is flat, and the reinforcing ribs project from both sides of the back surface along both sides of the walking board, and the center of the back surface is in the middle. The reinforcing ribs are projected in parallel with the ribs on both sides of the back surface at a position shifted from one side to the other side, and on the storage side of the walk board, the back surfaces of the pair of walk boards are arranged so as to face each other. By arranging the ribs of the other walk plate between the ribs of the plates, the pair of walk plates are superposed, and in this state, they are housed in the rear door.

(Operation) By inserting a pair of step plates that are superposed in the rear door, the pair of step plates are stored easily and invisible from the outside.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 3 shows an example of a cargo handling vehicle provided with the step board storage device of the present invention.

In FIG. 3, reference numeral 2 denotes a support frame 2 which is tiltably provided on a vehicle frame 1 with a pivot 3, and a load box 5 is mounted on the support frame 2 so as to be slidable back and forth. A dump cylinder (not shown) for tilting the support frame 2 is provided between the vehicle frame 1 and the support frame 2, and a slide cylinder 6 for sliding the load box 5 back and forth is provided between the support frame 2 and the load box 5. There is.
And these dump cylinder and slide cylinder 6
By extending the load box 5, the load box 5 can be slid rearward on the support frame 2 to a position where the rear end of the load box 5 is close to the ground while being tilted at an appropriate angle as shown in FIG.
By arranging the pair of walking boards 10, 10 between the rear end of the luggage box 5 and the ground in the state where the luggage box 5 is arranged in this manner, vehicles and the like can be loaded and unloaded.

As shown in FIG. 2, the step board 10 has a front surface 11 formed as a conveyance surface. The back surface 12 of the walk board 10 is formed in an uneven shape by reinforcing ribs 13a, 13b, 13c arranged in the lateral direction. The central rib 13b is formed so as to be shifted to one side from the center so that the walk boards 10 and 10 can be easily overlapped. Further, at one end of the walk board 10, a locking portion 15 that engages with an engaging portion formed at the rear end of the luggage box 5 is provided.

Then, the pair of walking boards 10, 10 are, as shown in FIG.
It can be housed in a rear door 7 provided at the rear of the luggage box 5 so as to be openable and closable around an upper hinge or a lower hinge. The rear door 7 is formed to have a hollow inside, and one end portion of the rear door 7 is opened to serve as an entrance / exit for the walk boards 10, 10.

Specifically, a worker places a pair of walking boards 10, 10 with their back surfaces 12, 12 facing each other and one side end portion and the other side end portion are arranged in reverse, and between the ribs 13a, 13b of one walking board 10. After the step plates 10 and 10 are overlapped with each other so that the ribs 13c of the other step plate 10 are incorporated into the rear step plate 10, the pair of step plates 10 and 10 are attached to the rear door 7
It can be housed inside the rear door 7 by inserting it through the inlet / outlet opening at one end. In addition, the walk board 10,1
0 is not necessarily stored after being polymerized, but may be stored individually. Further, an elastic body 8 is provided on the side wall of the rear door 7 for accommodating the walk boards 10, 10 stably without rattling.

The step board storage device of the present invention is not limited to the cargo handling vehicle as in this example, but can be used in other vehicles such as a dump truck and a vehicle with a fixed cargo box.

(Effect of the Invention) As described above, according to the present invention, by accommodating a pair of stacked walk boards in the rear door, the walk boards are exposed without exposing the back surface or front surface of the walk board. It can be stored, and it can be stored neatly, and it is sufficient to provide only one storage portion for easy manufacturing, and the work can be performed easily and quickly.

Furthermore, while the walk board is formed on a transport surface having a flat surface, ribs for reinforcement are provided on both sides of the back surface so as to project along the both sides, and in the middle of the back surface, one side from the center is provided. Reinforcing ribs are provided at the shifted positions so as to project in parallel with the ribs on both sides of the back surface, and the back surfaces of the pair of walking boards are arranged to face each other when the walking boards are stored. By arranging the ribs of the other walk plate on the other, the pair of walk plates are overlapped, and by storing in this state in the rear door, the thickness of the pair of walk plates at the time of storage is one walk plate. Since it can be made substantially the same as the thickness of the rear door, the storage space in the rear door can be made small, and the thickness of the rear door can also be made thin.
