Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention provides a load collapse prevention device for a wing body vehicle, which has a wing portion at both ends of a floor of a truck bed, and a wing that integrally opens a side plate portion above the tilt portion upward from a center of a ceiling portion. Regarding

[0002]

[Prior art]

 There is known a wing body vehicle C provided with a so-called wing 5 that integrally opens upward from a ceiling portion of a luggage platform to an upper portion of a side plate (see FIG. 5).

In addition, as a technique for preventing the collapse of the load loaded on the loading platform, for example, as shown in FIG. A technique of fixing with a belt 23 and a technique of preventing a collapse of a load by packing a paper airbag between the loads in the case of a small load are known.

[0004]

[Problems to be solved by the device]

 However, the above technique has a problem that when one wing is opened, the load is pushed out by the tension of the belt on the other side, and the loading is troublesome and troublesome.

Further, although there are JP-A-60-89050, JP-A-61-152519, JP-A-60-43422, and JP-A-61-3136, there are belts in a luggage carrier. The problem of the present application is not solved by the method of hanging the wing, the technique for opening and closing the wings, and the technique for partitioning the van type luggage carrier.

An object of the present invention is to provide a load collapse prevention device for easily and reliably holding a load accommodated in a wing body vehicle.

[0007]

According to the present invention, there is a flank portion on each side of the floor of a truck bed, and the side plate portion above the tilt portion is integrally opened upward from the center of the ceiling portion. In a load collapse prevention device for a wing body vehicle having wings, an air mat for supplying air from a vehicle air source is provided on the tilting part of the loading platform and the side plate part of the wing.

Further, according to the present invention, there is provided a wing having a flank portion at both ends of a floor of a truck bed, and a side plate portion above the flank portion being integrally opened upward from a center of a ceiling portion. In a cargo collapse prevention device for a wing body vehicle, a movable air mat that extends from the ceiling to the floor of the bed is placed in the center of the bed, and the air mat is configured to supply air from the vehicle air source. There is.

[0009]

[Action]

 In the cargo collapse prevention airbag curtain configured as described above, the air of the air anch is supplied to the airbag after the loading is finished and the wings are closed. Since air enters the air bag, it expands and holds the cargo.

[0010] For example, when the shape of the load cannot be largely divided into right and left, the load is held from the outside of the upper portion and the lower portion, or when the shape of the load is small, the load is moved from the center of the loading platform toward the side. Select the bed to hold and hold.

[0011]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 3, swing parts 2 and 2 are rotatably provided at both ends of a floor 1 of a cargo bed via hinges 1a and 1a, and a center member 10 provided on a ceiling portion of the cargo bed is provided. Wings 5, 5 are rotatably attached.

A hollow air mat 3 made of rubber and an air mat 6 are attached to the inside of the tilt portion 2 and the inside of the side plate portion of the wing.

A plurality of pressing members 4 are attached to the air mat 3 and the air mat 6 so as to protect the air mat and press the luggage.

Further, a rail 11 is provided on the center member 10, and a plurality of air mats 12 (in the example shown in the figure, divided into three parts in the up and down direction) which are divided in the up and down direction and the longitudinal direction of the bed are connected by a connecting member 13. And is movably attached to the rail.

Further, a hook 24 is provided in the lower part of the air mat and can be fixed by using a hook portion 25 on the floor of the loading platform and a rubber band belt or the like, so that the load can be loaded even on only one side of the loading platform. Retained. A general-purpose material can be used for the hook on the floor.

A plurality of pressing members 14 are attached to both side surfaces of the air matt 12.

The pressing members 4 and 14 are formed of a thin iron plate or plywood, and the shape and size of the air mat 3 and the air mat 12, for example, the shape and size of the air mat 3 and the air mat 12 are determined.

FIG. 4 shows an example of a supply device for supplying air from an air source of the vehicle to the air bag, and the sub tank 15 is connected to an air tank of the vehicle (not shown) through a check valve 18.

The sub-tank 15 is connected via a check valve 18 and a pressure regulating valve 16 to a switching valve 17 for switching an air mat between the sub-tank 15 and an air cleaner 19 of the engine. The switching valve 17 checks with the air cleaner 19 of the engine. It is connected to an air mat (not shown) via the valve 18.

A plurality of switching valves 17 may be provided depending on the number of air mats.

Therefore, for example, when carrying a large load, select a bed with an air bag inside the wing side plate and tilt, and for a small load, select the one with an air bag at the center. Then, after the loading work is completed, the wings 5 are closed, the air in the sub tank 15 is supplied to the air mat by the switching valve 17, and the load is securely held by the air mat.

When unloading a load, the switching valve 17 is switched during engine operation to allow the air in the air mat to be sucked into the engine via the air cleaner 19, so that the airbag quickly contracts and unloading does not take time. .

[0024]

[Effect of device]

 Since the present invention is configured as described above, by simply supplying air to the air bag after closing the wings, the air bag can hold the load and prevent the load from collapsing.
