【考案の詳細な説明】 「産業上の利用分野」 この考案は、貨物自動車の幌装置に関し、特に、アオリ
の高い荷台に用いる伸縮自在な幌掛装置に関する。DETAILED DESCRIPTION OF THE INVENTION "Industrial application field" The present invention relates to a hood device for a freight vehicle, and more particularly to a retractable hood device used for a cargo bed with a high tilt.

天蓋をシリンダーで回動させるようにしていた。[Prior Art] Conventionally, as a retractable hood hanging device for a freight vehicle, as in Japanese Utility Model Publication No. 55-8654, arch-shaped hood support frames are arranged in parallel, and link rods are provided on the front and rear support frames. It was pivotally attached and the support frame was moved by the expansion and contraction of this link rod. In addition, as in Japanese Patent Publication No. 59-3286, in a dump truck or the like having a high tilt, a canopy pivotally attached to both sides of a cargo bed is rotated by a cylinder.

なる欠点があった。[Problems to be Solved by the Invention] However, among the above-mentioned conventional techniques, the one that opens and closes the arch-shaped hood support frame along the cargo bed has an advantage of being able to store a load, but is stable. In the case of poorly loaded cargo, many cargos could not be loaded, and there was an unnecessary space between the cargo and the hood. Further, since the top of the hood is high, the stability is poor, and it is necessary to provide a plurality of rolling wheels on the rail. Moreover, there was a drawback that you could not go to a low building. Also, a canopy that can be opened and closed on both sides of the cargo bed has the advantage that the vehicle height can be relatively lowered, but a space for accommodating the canopy, etc. is required on the side of the vehicle, and the items can be placed from the side. There was a drawback that the canopy interfered with the loading.

This will be described in detail with reference to the attached drawings. The gist of the matter is that a large number of rolling wheels are rotatably arranged on guide rails on both sides of a cargo carrier bed.
This roller is provided with a hood support frame using an extendable link rod, and the last one of these hood support frames is fastened to the drive medium stretched along the guide rails and In the device for opening and closing the hood by moving the wheels to the front and rear of the loading platform, the lower horizontal rods are fixed to the rolling wheels on both sides, and the lower ends of the pair of link rods are pivotally attached to both ends of the front and rear lower horizontal rods. Wear, and the upper end of this link rod is rotatably connected to the upper horizontal rod so that it can be folded upward, and at the same time, it is flexibly connected to regulate the lower horizontal rods at the front and rear at predetermined intervals. An abutting plate, which is longer than the diameter of the rolling wheels, is fixed to the lower lateral rod in the vicinity of each rolling wheel, and is projected in front of and behind the rolling wheels.

That is, as shown in FIG. 2, the lower horizontal rod at the rear end of the loading platform is pulled toward the driver's seat, the link rod is folded, and the lower horizontal rod at the front side is pressed to contract a series of link rods one after another. Then, the hood can be opened by moving the hood support frame as shown by the phantom line in FIG. At this time, the abutting plates can prevent the front and rear wheels from coming into contact with each other, and can be prevented from interfering with each other and hindering the rotation. Then, to close the hood sheet, the rope may be pulled in the opposite direction. That is, the lower horizontal rod at the rear end, which is fastened to the rope, is towed to extend the link rod, and the chain connected to the front and rear link rods restricts the opening movement and moves backward in that state, so the next lower rod The horizontal rod is pulled to open the link rod, and the hood is traveling toward the rear end of the loading platform one after another,
The hood sheet can be closed.

In FIG. 1, reference numeral 8.8 is a pulley that is supported on the front and rear sides of the loading platform 6, and a rope 7.7 is hung around guide rails 1.1 on both sides of the loading platform.
It is driven by. Then, as shown in FIG. 2, a large number of rolling wheels 10 ... A lower horizontal rod 3 is connected to the axis of a pair of rolling wheels 10.10 which are mounted on the guide rails 1.1 on both sides of these rolling wheels 10. As shown in FIG. 2, the lower ends of the link rods 4 are pivotally attached to both ends of the lower horizontal rod 3, and the upper ends of the front and rear link rods 4.4 are attached to each other, and the attached link rods 5.5 on both sides are attached. It is pivotally attached to the upper horizontal rod 5 to form a hood support frame. Chains 2.2 are connected to the front and rear lower horizontal rods 3 and 3 to regulate the distance between them, and the opening of the front and rear link rods 4.4 whose upper ends are pivotally attached to the upper horizontal rod 5 is regulated. . Reference numeral 8.8 is a pulley supported on the front and rear sides of the loading platform 6, and as shown in FIG. 1, ropes 7.7 are hung around guide rails 1.1 on both sides of the loading platform, and the forward / reverse motor 9 drives the ropes. 7.7 is set to move. A rope 7.7 is fixed to both sides of the lower horizontal rod 3 of the support frame at the rearmost end of the hood support frame, and if the motor 9 is driven to pull the rope toward the driver's seat (arrow a) Direction), the lowermost horizontal rod 3 at the rearmost end shown in FIG. 2 is pulled to the driver's side, and the front and rear link rods 4.
Fold 4 and fold the front link rod 4.4 while pressing the lower side rod 3 ...
As shown by the phantom line in the figure, the hood sheet 14 is folded toward the driver's side. Then, when the motor 9 is driven in the opposite direction, the hood sheet 14 causes the lowermost horizontal rod 3 at the rear end of the lower horizontal rod 3 to be pulled to the rear of the loading platform 6 and the front and rear link rods 4.4 to be located between the front and rear lower horizontal rods 3.3. It is opened to the length of the connected chain 2 and the front and rear hood support frames are towed by the chain 2 connected to the hood support frame at the rear stage and, as shown in FIG.
Can be closed. In addition, each lower horizontal rod 3 ・
Abutting plates 12 longer than the diameter of the rolling wheels 10 are fixed near the rolling wheels 10.10 on both sides, and are projected in front of and behind the rolling wheels 10. And when the link rod 4.4 is folded, the rolling wheel 1
The front part of 0 comes in contact with the rear part of the front wheel 10, and is provided to prevent the braking action due to the difference between the forward and reverse rotation directions of the contact part. The tips are in contact with each other so that the front and rear wheels do not come into contact with each other. Reference numeral 13 is a frame,
As shown in FIG. 4, both ends of the lower horizontal rod 3 on the driver's seat side are locked to the frame 13, and the link rods 3 ... Are folded and stored in this portion. The hood sheet 14 is stretched by engaging with the respective upper horizontal rods 5 ... And the lower horizontal rods 3.3 at the front and rear ends.

As compared with a conventional hood supporting frame having an arch shape, the hood expanding and contracting device is lower and the number of rolling wheels is smaller, so that the storage space is smaller. In the device of the present application, an abutment plate longer than the diameter of the rolling wheel is fixed to the lower horizontal rod in the vicinity of the rolling wheel rotatably engaged with the guide rail, so that the hood support frame is folded and stored. At this time, unlike the conventional device, the front and rear wheels do not come into contact with each other and do not interfere with each other, and the horsepower of the drive device is small.
