CONSTITUTION:A strut 4 is vertically provided in front and rear both sides of a load bed 2 in a truck 1, and a guide rail 5 is mounted linking over the depth direction of the load bed between the front and rear struts. Mounting movably horizontal double V-shaped hood frame units 8, 9 to the guide rail 5 in both side directions of the load bed 2 through a guide unit 6, a hood frame is mounted being stopped to each hood frame unit 8, 9, and the hood frame opens and closes on the load bed 2 by moving the hood frame units 8, 9. The hood unit only covers between the bottom end of each hood frame unit 8, 9 and the upper end of a load bed swing unit 3, and a loading clearance R is provided. In this way, in a closed condition of the load bed swing unit 3 and a hood, loading work can be performed through the clearance R.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a truck sail device used in a dump truck or the like.

[Conventional technology]

Conventionally, this type of truck hood device was developed in Japanese Patent Application Laid-open No. 50-94.
628, Japanese Unexamined Patent Publication No. 55-79714, Japanese Utility Model Application No. 57-131325, etc. are known.

In this conventional structure, guide rails are provided on both the left and right sides of the truck bed in the depth direction of the bed, and multiple mouth-shaped hood frames are arranged in parallel between the left and right guide rails so that they can be moved in the depth direction. A top body made of vinyl sheet or the like is fixed to the vehicle, and the cargo platform can be opened and closed using the top body by moving each of the top frame bodies.

[Problem that the invention seeks to solve]

However, in the case of the above-mentioned conventional structure, the guide rails are attached to gate bodies that are installed on both the left and right sides of the loading platform so that they can be raised up and down, and the hood frame is attached to these guide rails, so when the loading platform is blocked by the pillow bodies, the hood cannot move. The frames are located parallel to each other on both sides of the loading platform, and even if the pillows on the sides of the loading platform are rolled up, the presence of the hood frame prevents loading from the sides of the loading platform.
For this reason, when loading the vehicle, the canopy frame must be moved to open the loading platform, which is disadvantageous in that the loading operation is troublesome.

[Means for solving problems]

The purpose of the present invention is to eliminate these inconveniences, and the gist thereof is to provide guide rails in the depth direction of the loading platform on both the left and right sides of the loading platform of a truck, and to place a mouth-shaped hood frame between the left and right guide rails. A plurality of pieces are arranged in parallel so as to be movable in the depth direction, a sleeper is fixed to the six-fold frame, and the cargo bed can be opened and closed by the sleeper by moving each of the top frames, in which a support is attached to the cargo bed. erected, the guide rails are installed on the supports, and a loading gap is provided between the lower ends of the plurality of canopy frames and the upper edges of the flaps on both the left and right sides of the loading platform. This is a feature of the truck hood device.

[Effect]

The guide rail is constructed by struts erected from the loading platform, and the loading gap between the lower end of each canopy frame and the upper edge of the door flaps on both left and right sides of the loading platform allows loading from the sides of the loading platform in a closed state.

〔Example〕

1 to 7 show an embodiment of the present invention, where 2 is a truck, 2 is a loading platform, and gate bodies 3 are provided on both left and right sides of the loading platform 2 so as to be able to stand up and fall down.

Reference numeral 4 denotes pillars, which are erected at the front and rear of the left and right sides of the loading platform 2, and square pipe-shaped guide rails 5 are installed between the pillars 4, respectively.

Reference numeral 6 denotes a guide body, which is movably provided on the left and right guide rails 5 by three guide rollers 7, and a side rod part 8a of a retractable mouth-shaped canopy frame body 8 is fixedly mounted on the left and right guide bodies 6. However, a cargo gap R is provided between the lower end of the side rod portion 8a and the upper edge of the gate body 3.

9 is another hood frame, which is arranged between adjacent hood frames 8;
It is formed into an expandable opening having almost the same shape as the canopy frame 8, and there is also a cargo gap R between the lower end of the side rod portion 9a and the upper edge of the flap body 3.
has been established.

Reference numeral 10 denotes a telescopic mechanism, in which a mounting body 11 is fixed to the upper side of the side rod 9a of the other hood frame 9, and a sliding body hill is provided below the side rod 19a so that the hood frame 8 can be slid up and down. A mounting body 13 is also fixed to the side rod part 8a so that it can be adjusted up and down, and a push-up link 14 is pivotally installed between the mounting body 11 and the adjacent mounting body 13, and the middle of the push-up link 14 and the sliding body An intermediate link 15 is pivotally installed between them, and a transfer row 4 = 16 is provided for the mounting weight 1, and one side of the upper rod portion 8b of the frame 8 is provided. This connecting body 17 is fixed, and a connecting weight 9 having a sliding slot on the other side is fixed, and the pivot 20? The X-links 21, whose intermediate portions are pivotally connected to each other, are disposed between adjacent canopy frames 8, and each end of the X-links 21 is connected to a connecting body 1 that faces each other.
7 or a slide with an elongated hole.

A pillow body 22 is made of a vinyl sheet or the like, and is fixed to the canopy frame 8 and the bone frame body.

Since this embodiment has the above-mentioned configuration, when the top frame body 8 is moved along the guide rail 5 in the loading platform closed state shown in FIG.
5, the upper rod portions 8b and 9b of the top frame 8 and the other top frame 9 move upward from the same height position as shown in FIG. 5, as shown in FIG. , and the X-link 21 between the top frames 8 rotates around the pivot 20 as shown in FIGS. 6 and 7, and the top frame 8 and other top frames 9 are adjacent to each other, and the cargo bed 2 is opened. state.

In addition, since a loading gap R is formed between the lower end of the top frame 8 and other top frames 9 and the upper edge of the flap body 3, loading can be carried out from the side of the cargo bed 2 when the cargo bed is closed. If the gate body 3 is laid down, loading work can be carried out more easily.

〔Effect of the invention〕

As described above, in the present invention, since the loading gap R is formed between the lower ends of the plurality of canopy frames and the upper edge of the gate body, loading can be carried out from the side of the loading platform when the loading platform is closed, increasing the efficiency of loading operations. can be improved.

As described above, the intended purpose can be fully achieved.
