Abstract

PURPOSE: To open/close a side flap by interlocking with opening/closing of wing panels of a wing car so as to improve cargo handling workability by forming the side flap in such a state as laid down outward due to loosening of tensile force of a wire for hanging the flap, when the wing panels are swung in the opening direction. CONSTITUTION: A guide rail 16 is mounted on an upper girder 12 in the rear end in front of a deck 2 and a link 15 is erected over a slider 17 guided by this guide rail 16 and a top wall 6 of respective wing panels 3. When the inside end 15a of the link 15 is raised in the case of opening of the wing panels 3, the slider 17 connected to the outer end 15b of the link 15 is made to move along the guide rail 16 and a wire 20 for hanging a flap is let out from the inside end of the guide rail 16. A side flap 4 is thus laid down outward and opened. On the other hand, when the wing panels 3 are moved to be closed, the slider 17 is moved inversely via the link 15 so that the side flap 4 is closed by drawing back the wire 20.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic opening / closing device for a side tilt of a wing vehicle.

In this specification, "inside" refers to the inside of the wing vehicle, and "outside" refers to the outside.

[0003]

2. Description of the Related Art Conventionally, a wing vehicle has a pair of wing-shaped panels having an inverted L-shaped cross section, which are swingably attached to the left and right sides of a girder at the center of the upper surface of a box-shaped bed, and the left and right edges of the bed. The wing-shaped panel and the side tilt were opened and closed separately, although the wing-shaped panel and the side tilt were attached so as to be swingable by about 180 °. That is, the opening and closing of the wing-shaped panel was automatically performed by a hydraulic cylinder or the like, but the opening and closing of the side tilt was performed by hand in most cases.

[0004]

However, the side portion is extremely heavy, and it is very burdensome to manually open and close such a heavy side portion, such as the waist and wrist. There is a risk of damage to the cargo, and it has been a major issue to reduce the burden on the operator when opening and closing the tilt and to reduce the work load.

Therefore, conventionally, an arm for supporting the side tilt at the time of opening and closing is attached to the outer surface of the lower end of the panel forming the side tilt, and an air spring or the like is made to act on this arm to perform the work for opening and closing the tilt. It was attempted to reduce the burden on workers and to reduce the work load.

However, in such a conventional side opening / closing device, since the tilting support arm is largely overhanging on the outer surface of the box-shaped carrier, it is dangerous when the wing vehicle is running. There is a problem that the luggage loading space is narrowed because the inner dimension of the luggage carrier must be reduced when the luggage carrier is manufactured, because the arm for supporting the tilting is extended outward.

The object of the present invention is to solve the above-mentioned problems of the prior art, and when the wing-shaped panel of a wing vehicle is opened and closed, the side tilt can be automatically opened and closed in association with it, and the operator's The burden is very small, the cargo handling work can be reduced, and there is no protrusion on the outer surface of the tilt, so it is possible to secure safety during traveling, and it is possible to take a wide internal dimension when manufacturing the cargo bed. It is an object of the invention to provide an automatic opening / closing device for a side tilt of a wing vehicle that can expand a luggage loading space.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention has a pair of L-shaped transverse cross sections which are swingably attached to both left and right sides of a girder in the center of the upper surface of a box-shaped carrier. In a wing vehicle equipped with wing-shaped panels and side tilts that are swingably attached to the left and right edges of the luggage carrier, a device that automatically opens and closes the side tilts in conjunction with the opening and closing operation of the wing-shaped panels. The inner ends of the links are pin-connected to the front and rear ends of the top wall of each wing-shaped panel. Guide rails are attached to the front upper girders of the torii and the rear upper girders that connect the rear columns of the rear ends of the loading platform, and the sliders guided by these guide rails are pin-connected to the outer ends of the links. , A pair of front and rear on the slider The upper ends of the wire for suspending and tilting are respectively connected, and the middle part of the length of the wire is connected to the torii at the front end of the loading platform and the rear upper girder at the rear end of the loading platform and the pulleys provided at the required positions of the rear columns, respectively. It is hung and the lower end of the wire is connected to the front and rear ends of the side tilt.
By swinging each wing-shaped panel in the opening direction, the inner ends of the front and rear links are pulled up, and the sliders connected to the outer ends of both links move along the guide rails.
Both the front and rear tilting wires are extended from the inner ends of the guide rails, the side tilting tilts outward, and they swing in the closing direction of each wing-shaped panel. The gist is an automatic opening / closing device for the side tilt of a wing vehicle, which moves in the opposite direction to the above direction and pulls back both front and rear tilt wires to raise the side tilt.

[0009]

In the above, when the left and right wing-shaped panels of the wing vehicle are closed, the side tilts are vertically erected at the left and right side edges of the loading platform. The links attached to both ends are arranged in a substantially horizontal shape, and the sliders provided with, for example, rollers coupled to the outer ends of the links are respectively located at the outer ends of the guide rails, and the front and rear tilting wires are attached. Is pulled back most, and the side tilt is pulled up by both wires.

Now, when the wing-shaped panel swings in the opening direction, the inner end of the link is pulled up by the top wall of the wing-shaped panel, and along with this, the slider at the outer end of the link follows the guide rail. Move inward, the tensile force of the wire for lifting and tilting is loosened, the wire is paid out from the inner end of the guide rail, and the side tilt is approximately 1 outward.
It falls 80 degrees.

Thus, the tensile force of the wire acts on the side tilt during the tilt of the side tilt to the outside,
Since the weight of the side tilt is received, the burden on the operator is reduced. The pulling force of the wire is adjusted so that the weight of the side tilt itself causes the wire to be in a fully opened state so that the side tilt eventually falls down by about 180 °.

Next, when the wing-shaped panel swings in the closing direction contrary to the above case, the inner end of the link is pushed down by the top wall of the wing-shaped panel, and the outer end of the link is accordingly pushed. The slider moves along the guide rail in the outward direction opposite to the above, pulling back the tilting wire,
The side tilt is raised.

In this way, when the wing-shaped panel of the wing car is opened / closed, the side tilt can be automatically opened / closed in association with the opening / closing of the wing-shaped panel, so that the burden on the operator is very small and the cargo handling work is reduced. Can be planned.

In addition, in the running state of the wing vehicle in which the side tilt is raised vertically, there is almost no protrusion outward from the box-shaped carrier, and safety during running can be ensured. . Moreover, since there are almost no protrusions outward from the box-shaped carrier, the inner dimension of the carrier can be widened when the carrier of the wing vehicle is manufactured, and the luggage loading space can be expanded.
