Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a van-type vehicle. More specifically, at the rear opening of a van-type vehicle,
This invention relates to an auxiliary span plate for a van-type vehicle having a door structure in which the upper side is a double door that rotates laterally or a shutter door that is stored in the attic, and the lower side is a fan that rotates up and down. be.

(Prior art) Conventionally, in a van type vehicle having a door structure with a double door or shutter door on the upper part and a fan on the lower part,
When a van-type vehicle is backed up to approach a platform, the double door or shutter door is opened, and the fan is laid down almost horizontally on the platform to serve as a gangboard, when loading and unloading cargo using casters or pallets, A relatively wide recess A (Fig. 3) was formed between the rear edge of the platform and the lower edge of the fan, which caused problems in loading and unloading pallets, etc.

For this reason, in the past, a plate such as plywood was further laid over the recess A to cover the recess so as not to hinder the transportation of pallets, etc.;
This was easy to move because it was simply placed on top, and whenever the fan was used as a spanning board, the board had to be laid in a recess, which was very cumbersome.

(Problems to be Solved by the Invention) The present invention provides an auxiliary span plate with improved fanning in view of the above-mentioned problems of the conventional plate covering the recess.

(Solution by invention) In conjunction with the opening/closing operation of the fan, when the fan is laid down approximately horizontally, the relatively wide recess formed between the rear edge of the loading platform and the lower edge of the fan is automatically removed. can be covered with an auxiliary gangboard.

(Example) The structure of the rear part of a van-type vehicle will be outlined with reference to FIGS. 2 and 3. 1 is a van-type vehicle, and the upper part of the rear department entrance is a shutter door 2, and the lower part is also closed with a fan 3. 4 is a platform, and when unloading the cargo from the van-type vehicle 1 onto the platform 4, the fan 3 is folded down as shown by the two-dot chain line in the figure, and the platform 4 is bridged between the rear floor of the van-type vehicle and the platform 4, and the cargo is transported on top of this. It was being carried in implement 5 (Figure 3).

In this case, as described above, a recess A was formed at the rear of the floor, which hindered the movement of the carrier 5.

FIG. 1 shows the present invention which solves this problem, in which the fan 3 is hinged at the rear of the vehicle with a hinge 6 like in the conventional type. 7 is an auxiliary spanning board newly added in the present invention. The base of the auxiliary gangboard 7 is connected to the van-type vehicle 1.
It is pivotally supported by a hinge 8 fixed to the upper surface of a rear lower frame 9. When the fan 3 stands upright as shown by the imaginary line in FIG. 1, it is positioned exactly inside the fan 3. 10 is a holding member for the auxiliary spanning board 7;
As shown in FIG. 4, they are L-shaped and are attached to the inner surface of the fan 3 in left and right pairs. The auxiliary span plate 7 rotates around the hinge 8 along with the rotation of the fan 3. At this time, since both sides of the auxiliary spanning board 7 are relatively slidable within the holding member 10, the auxiliary spanning board 7 and the fan 3 can be opened and closed smoothly even if their rotation centers are different.

(Function) The fan is rotated from the vertical position shown by the imaginary line in FIG. 1 to the horizontal position shown by the solid line to serve as a spanning board between the platform 4. It rotates while being held on both sides by L-shaped holding members 10 fixed in pairs on the left and right sides. The relative distance relationship between the hinge 8 at the lower end of the auxiliary span plate 7 and the holding member 10 changes from l to L as shown in FIG.
At this time, since the auxiliary span plate 7 and the inner surface of the holding member 10 are in slidable contact with each other, the fan 3 can be smoothly rotated toward the horizontal position.

Now, when it comes to the horizontal position, as shown in Figure 1, there is a recess A created between the fan 3 and the rear lower frame 9 of the van type vehicle.
The upper part of the vehicle is covered with an auxiliary span plate 7, so that the wheeled carrier 5 shown in FIG. 3 can be smoothly moved between the vehicle floor and the platform 4.

(Effects) Since the auxiliary spanning board 7 is connected to the opening and closing of the fan 3, there is no need to install another spanning board, which requires troublesome work. In addition, since one end of the auxiliary span plate 7 is attached to the rear lower frame by a hinge 8, the auxiliary span plate 7 does not move when the wheeled carrier 5 is carried in or out, so that the carrier can be carried out easily. The workability of loading has been significantly improved.
