Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a load carrier covering device for a motor vehicle having a load carrier such as a dump truck, a truck, a trailer and the like, which can prevent the load from scattering and getting wet.

[0002]

2. Description of the Related Art Conventionally, in order to prevent a load loaded on a truck from traveling from falling from the loading platform or getting wet with rain, the entire loading platform should be covered after the luggage is loaded on the loading platform. I covered the seat with a rope and tie the seat to the bed with a rubber belt.

In some cases, seat frames provided with seats are provided on both sides of the carrier, and both seat frames are tilted inward to cover the load to some extent.

[0004]

However, it would take a lot of time and labor to cover the above-mentioned load on the bed of the truck with the sheet material by hand, which is very troublesome. It was not preferable in terms of efficiency. Further, even when the seat frame is tilted inside the cargo bed to cover the load, there is a concern that the load cannot be completely covered and the load is scattered during traveling.

The present invention was developed in view of the above points, and an object of the present invention is to provide a vehicle loaded with a luggage carrier such as a truck so that a load loaded on the luggage carrier can be removed during traveling. Another object of the present invention is to provide a load carrier covering device for an automobile, which can surely prevent the vehicle from scattering and getting wet with rain.

[0006]

The present invention has the following constitution in order to effectively achieve the above object. That is, a stretchable sheet material is wound around a cylindrical body or a columnar body equipped with a spring mechanism, and the cylindrical body or the columnar body is rotatably provided at the front end of a loading platform such as a truck, and the elastic sheet is stretched by the spring mechanism. A swinging rod that constantly urges the material in the direction of winding the material into a cylindrical body or a cylindrical body, and that can move the tip from the front end to the rear end of the loading platform is swingably provided on at least one side of the central portion of the loading platform. The tip of the rocking rod is connected to the tip of the elastic sheet material, and the rear end of the rocking rod is connected to an actuating means provided at the lower part of the loading platform. The elastic sheet material is pulled out from the cylindrical body or the cylindrical body against the elastic force of the spring mechanism, and the luggage carrier can be covered with the elastic sheet material.

[0007]

With the structure of the load carrier covering device for an automobile of the present invention as described above, when the load loaded on the load carrier such as a truck is covered with the elastic sheet material, it is rocked by activating the actuating means. The rod rotates and moves its tip in the rearward direction of the luggage carrier with a point pivotally supported on the side portion of the central portion of the luggage carrier as a fulcrum. As a result, the elastic sheet material is pulled out from the cylindrical body or the cylindrical body against the elastic force of the spring mechanism, and the tip of the elastic sheet material connected to the tip of the swing rod moves to the rear end of the loading platform. However, the loaded stretchable sheet material covers the cargo on the bed. At this time, the drawn elastic sheet material is constantly pulled toward the cylindrical body or the cylindrical body side by the elastic urging force of the spring mechanism. Can be coated so as to abut. Of course, the bed can be covered even when there is no load.

Further, in order to release the state of being covered with the stretchable sheet material, the actuating means is actuated to rotationally move the swing rod to the front end side of the loading platform. At this time, the stretchable sheet material that has been pulled out is wound around a cylindrical body or a columnar body by the elastic force of the spring mechanism, and when the tip of the swing rod comes to the front end side of the loading platform, the stretchable sheet material is , Is almost completely wound into a cylindrical body or a cylindrical body, and the covering of the bed is released.
