2. Description of the Related Art Conventionally, there is a wing vehicle in which an L-shaped roof is opened and closed in conjunction with opening and closing of a side fan (Japanese Utility Model Publication No. 63-41271). As shown in FIG. 6, a front wall erected on the front edge of the loading platform a, a rear wall erected on the rear edge of the loading platform a, and a central frame b erected at the upper center of the front wall and the rear wall.
And two shafts c attached to the front wall and the rear wall along the central frame b
₁ , c ₂ , L-shaped roof d attached to each shaft, and one end L
An L-shaped link e connected to the mold roof d so as to rotate together with the L-shaped roof d, a side fan f rotatably mounted on the side surface of the loading platform a, and the link e and the side fans f, f. Connect to the side fan
Is opened, the link e rotates and the L-shaped roof d opens, and the side fan f
When the link is closed, the link e rotates and the L-shaped roof d is closed, and the pulleys h ₁ , h ₂ , h for guiding the rope g
_The L-shaped roof d opens and closes in conjunction with the opening and closing of the side fan f. Originally, the L-shaped roof d is formed by integrating substantially half of the roof and the side portion above the side fan f into an L shape, and is considerably heavier in weight balance than the side fan f. And L
Type roof d is adapted to rotate integrally with the rotation shaft c _1. The rotation is performed by operating an L-shaped link e attached to the shaft c _1, and the rotation requires a considerably large force. As described above, in the conventional opening / closing device for a wing vehicle, the L-shaped roof d is rotated in conjunction with the opening and closing of the side fan f. It is a very difficult problem to easily open and close the L-shaped roof d by slightly applying the force.

[0003]

SUMMARY OF THE INVENTION In view of the above-mentioned problems of the prior art, the present invention solves the problem of weight imbalance between a side fan and an L-shaped roof, and if the side fan is operated, the weight can be easily reduced. Big L
The object is to enable the mold roof d to be automatically opened and closed.

[0004]

A loading platform, a front wall erected on a front edge of the loading platform, a rear wall erected on a rear edge of the loading platform and hinged to a side pillar of an opening / closing door, and the front wall. An L-shaped roof 1 that is supported between the front and rear walls so as to be rotatable up and down, a side fan 4 hinged to a side edge of the loading platform, and the side fan 4 and an upper part of the front and rear walls. A wire 14 stretched between a lever-type rotating device provided in the groove-shaped recess 9 and a spring having one end pivotally connected to the front or rear wall and the other end to the L-shaped roof 1. And a small ammunition 6 provided near the upper corners of the front wall and the rear wall, and the lever-type rotating device is provided in the upper channel-shaped recess 9 of the front wall and the rear wall. An arm 11 having an intermediate portion pivotally attached to the arm 10, a roller 12 pivotally supported on the upper end of the arm 11, and a wire 14 fixed to the lower end of the arm 11 are provided. Wa The other end of the wire 14 is fixed to a wire fitting 16 provided on the side of the side fan 4 via pulleys 15a, 15b, 15c, and both front and rear ends of the L-shaped roof 1 corresponding to the rollers 12. A guide rail 13 is provided at the edge.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. Reference numeral 1 denotes an L-shaped roof, which is pivotally supported by a hinge 3 on a central support shaft 2 extending between a front wall (not shown) and a rear wall. Reference numeral 4 denotes a side fan which is pivotally supported by a lower frame member 5 with a hinge 5a. Numeral 6 denotes an ammunition such as a small spring or a gas damper attached to the upper corner of the rear wall. The ammunition 6 urges the L-shaped roof 1 in the opening direction (upward) when the roof 1 is closed.
When the L-shaped roof 1 is closed, a locking bracket 7 provided at the lower end of the L-shaped roof 1 and a locking device 8 provided at the lower side of the rear section opening are engaged and locked so as not to be opened. . However, once this is removed, the L-shaped roof 1 pivots slightly upward due to the elasticity of the ammunition 6, and the upper end of the side fan 4 and the L-shaped roof 1
A gap H is formed between the lower end and the lower end (FIG. 3). In this state, the hand can be put on the upper end of the side fan 4, so that the side fan 4 can be turned downward.

The peripheral edge of the rear section opening is a groove-shaped recess 9, and an arm 1 is attached to a bracket 10 fixed in the recess 9.
1 is pivoted about its center by a shaft 11a. Arm 1
A roller 12 is mounted on the upper end of the L-shaped roof 1 so as to roll along a guide rail 13 having a U-shaped cross section provided on a side frame of the L-shaped roof 1. One end of a wire 14 is fixed to the lower end of the arm 11. Wires 14 are pulleys 15a, 15b, 15c
The other end is fixed to a wire fitting 16 provided on the side of the side fan 4. Reference numeral 17 denotes a projectile such as a gas damper.

The locking device will be described with reference to FIGS. When the L-shaped roof 1 is closed, the U-shaped groove 7a of the locking bracket 7 fixed to the lower end edge engages with the hook 7b fixed to the side of the entrance. At this time, the metal fitting 18 fixed to the fan 4 hits the side of the gate and is not further rotated. Then, the user holds the handle 19 and pivots it upward. The hook 20 is hooked on the hook 7b, and the handle 19 is pulled down again to be locked. At this time, the metal fittings 18
Is trapped between the side of the portal and the latch 20 so that the side fan 4 is prevented from coming off.

[0008]

[Operation] (Closing the L-shaped roof 1) (1) Rotate the fan 4 upward to bring the fan 18 into contact with the side of the gate. At this time, since the wire 14 is relaxed, the arm 11 rotates around the shaft 11a. That is, the L-shaped roof 1 becomes free and descends by its own weight. (2) Close the L-shaped roof 1 downward, and make the U-shaped groove 7a of the bracket 7
Is engaged with the hook 7b. The handle 19 is turned upward with the handle 19, and the hook 20 attached thereto is turned upward to engage the hook 7b. Then handle 1
Pull down 9 to lock. ... Closed. (Opening of the L-shaped roof 1) (1) Conversely, when the handle 19 is turned upward to release the latch 20 from the hook 7b and release the lock, the lower end of the L-shaped roof 1 becomes free. Then, it is lifted slightly upward by the bullet 6. So put your hand on the upper part of the side fan 4 and pull it down, the side fan 4 will open to the side. At the same time, the wire 14 is strained,
Pull the lower end of the program 11. At the same time, the projectiles 17 extend upward against the weight of the L-shaped roof 1, and the L-shaped roof 1 automatically opens upward.

[0009]

[Effect] The side support 4 and the lower end of the arm 11 provided at the upper part of the gate were connected by a wire 14. The roller 12 provided on the upper part of the arm 11 is connected to the guide rail at the lower part of the side frame member of the L-shaped roof 1.
To move along line 13. A projectile 17 was provided on the L-shaped roof 1 and a small projectile 6 was provided at the upper corner of the entrance. With such a structure, the self-weight of the L-shaped roof 1 and the leverage of the arm 11 due to the pulling of the projectiles 17 and the wires 14 are well balanced, and the opening and closing of the side fan 4 and the L-shaped roof 1 are conventionally performed. It can open and close smoothly with a better balance. Further, since the upper end of the side fan 4 is easily grasped when the side fan is opened by the small ammunition 6, it is easy to put a hand on the side fan and it can be safely opened.
