Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a cargo box for a vehicle such as a truck, particularly a cargo box equipped with a canvas door.

<Prior art> As a loading box installed in a vehicle such as a truck,
In general, packaging boxes made of aluminum (so-called aluminum vans) and packaging boxes constructed by covering an arch-shaped support member with a canopy on a normal loading platform with a fan door are known.

However, the aluminum van has the following problems.

(1) Manufacturing costs are high because aluminum materials are expensive.

(2) When a door is provided on the side of a cargo box, there is usually only one door and it does not open wide, making it difficult to load and unload cargo from the side of the vehicle.

(3) Some doors are installed at the rear of cargo boxes that open wide to the left and right, but because they are designed to take advantage of the airtight nature of aluminum vans, they are heavy and the opening and closing operations are complicated. It is also necessary and troublesome to fix the door.

Furthermore, the following problems arose in the case of packing boxes made of canopies. That is, (1) Since the support member of the hood is supported on the fan door on the side, it is impossible to load and unload cargo from the side of the vehicle.

(2) The canopy has poor durability, and is easily damaged, especially near the poles of its supporting members, resulting in a short service life.

(3) Due to the form of the packing box constructed with a canopy, boxes such as cardboard boxes cannot be stacked without gaps, resulting in wasted space, resulting in poor space efficiency.

Further, although there is a shutter type door as a door provided at the rear of a conventional cargo box, there are problems in that it makes a high noise when opening and closing the door and is expensive.

Further, a side frame with a door that opens and closes left and right at the rear opening is surrounded by a hood via a frame, and one or more door curtains whose upper ends are continuous are provided above the door of this hood, and the door curtain is provided. Japanese Utility Model Application Publication No. 1983-9714 discloses a door opening in which the edge of the hood and the door curtain are connected with fasteners, and a door opening formed on the side or rear side of the luggage compartment of a van-type freight vehicle is disclosed. A guardrail is formed along the upper and lower opening edges, and a number of vertical rods each having a slider attached to at least the upper end are attached to a curtain member covering the door opening, and sutures are provided between the vertical rods. forming a curtain door, and engaging an upper slider of the curtain door with a guide rail formed at an edge of the upper opening;
Japanese Utility Model Application Publication No. 55-153226 discloses a foldable curtain door structure for a van-type freight vehicle in which the lower end of a vertical rod is fitted into a guide rail formed at the lower opening edge.

<Problems to be solved by the invention> However, with the method disclosed in Utility Model Application Publication No. 55-9714, the cloth door curtain must be manually rolled up and taken down, which takes time and effort to open and close. Since there is no means for engaging the curtain and the door, the door curtain is unstable and a gap is created. Furthermore, like the above-mentioned cargo box constructed with a hood, the supporting members of the hood are supported on the side frames, making it impossible to load and unload cargo from the sides of the vehicle, and the hood has poor durability, resulting in a long lifespan. In addition to being short-lived, there are other problems such as poor space efficiency, as the cargo box is made up of a canopy, making it impossible to stack items without any gaps, resulting in wasted space.

Furthermore, in the case of the one disclosed in Japanese Utility Model Application Publication No. 5-153226, opening and closing of the folding curtain door to the left and right must be done manually, which is time-consuming, and when opening and closing, the thin side frame members fall down. There is a risk that the upper and lower rollers may become wedged within the guide rail, making it impossible to open and close them smoothly.

Furthermore, in both of the above-mentioned Utility Model Application Publications No. 55-9714 and No. 55-153226, when a cloth door curtain or folding curtain door is opened, it remains at the edge of the opening even when it is fully opened. There was a problem in that the front surface of the opening could not be used widely, and therefore loading and unloading of cargo was difficult from this aspect as well.

This invention was devised in view of the above problems.
It is an object of the present invention to provide a vehicle loading box that has improved loading and unloading workability in the vehicle loading box, has good operability when opening and closing side and rear doors, is inexpensive to manufacture, and has excellent durability. purpose.

<Means for Solving the Problems> To achieve the above object, the cargo box of the vehicle of the present invention includes a canvas side door that is rotatably supported above and below the side opening of the cargo box, and a canvas side door at both ends of the door. a plate-shaped door body connected to each other, a fan door hinged to a lower end of the rear opening of the cargo box, and a reinforcing guide frame whose upper end is fixed to the upper edge of the rear opening and whose lower end is seated to cover the upper end of the fan door. A rear door of the canvas is provided with a guide roller at both ends, a guide frame that guides the roller up and down, and one end of a wire hooked to a guide pulley provided on the rear court frame of the rear opening is connected to the back of the canvas. It consists of a lifting mechanism connected to the lower end of the door and the other end to a balance weight that slides in the rear corner frame.

<Function> When opening the side opening of the loading box, by pulling the plate-shaped door body to the left or right, the canvas side door is folded to the left or right, and the side opening of the loading box is wide open. At this time, since the canvas side door is pulled or pushed while the plate-shaped door body is supported so as to be able to roll up and down, the canvas side door moves smoothly.

When opening the rear opening of the cargo box, by disengaging the rear canvas door and the fan door, the rear door of the canvas can be smoothly guided by the guide roller to the guide frame by the balance weight via the wire. It is pulled up and the rear opening is fully opened.
