Description

Cab cover on vehicle loading box

The present invention relates to a cover opening and closing device of the vehicle loading box, in particular, to facilitate the opening and closing of the cover to be covered in the loading box of the cargo vehicle carrying goods, soil or sand, to prevent the luggage in the loading box falling on the road while driving, When loading and getting off, it relates to a cover for opening and closing the vehicle loading box that can be easily worked through both sides as well as the rear of the vehicle.

The cover applied to a conventional vehicle loading box is a driver or operator spreads the cover to the top of the loaded cargo while a certain material, for example, goods, soil, or sand, is loaded into the vehicle loading box, and then installed on the rim of the cover. Dog's rubber bands are to be tied to the hooks of the loading box.

However, according to the above method, when soil, sand, or gravel is loaded at a height higher than the side wall of the loading box, a part of the material loaded in the loading box falls on the road through a gap formed between the cover and the side wall of the loading box. There is a problem such as causing.

In view of this, Korean Utility Publication No. 93-6871 suggested an opening and closing device of a vehicle loading box that automatically covers and covers the cover.

The opening and closing device of the vehicle loading box of the above-mentioned design is provided with guide rails in the longitudinal direction on both sides of the vehicle to slidably cover a plurality of cover bars, and to form an X-shaped link between the long grooves of the support. When the link connected to the air cylinder of the carbage moves through the guide rails, the carb support moves in parallel, so that the opening and closing movement of the cover can be installed by one air cylinder, and the rear support when the cover is covered. It is configured to cover the cover to the rear of the loading box by allowing the to rotate at a predetermined angle.

However, according to the above-described design, due to the air cylinder and the complicated link structure, the structure is very complicated, it takes much time and cost to install, and it is not economical. Since it is a multi-joint structure that must move simultaneously in the axial direction, it is difficult to expect the smoothness of the sliding operation, and there are various problems such as the opening and closing operation of the cover when the foreign matter is caught on the conveying rail.

Therefore, the present invention has been proposed in view of the above-mentioned problems, and its purpose is that the structure is extremely simple and does not need to change the structure of the existing vehicle loading box. The present invention provides a cover opening and closing device for a vehicle loading box having a structure that greatly reduces installation time and cost.

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

In FIG. 1, the loading box 3 is fixedly installed on the trailer 2 of the vehicle 1, and the cover opening / closing device of the present invention is installed in the loading box 3. Caba opening and closing device 4 of the present invention to form a box body space or to open both sides of the loading box 3 with the loading box 3, the front and rear support of the inverted U-shaped front and rear of the loading box 3 ( 5) (6) is fixedly installed to protrude high above the loading box. The fixing member 7 is fixedly installed across the center of the front and rear supports 5 and 6, and the front and rear supports 5 and 6 and the fixing member 7 form an H-shaped frame frame in plan view. do.

Rotating structures (8) are rotatably mounted by a plurality of hinges (9) on both sides of the fixing member (7), and the rotating structure (8) is a rod member (10) fixed to the hinge (9) and A plurality of L-shaped support members 11 welded and fixed to the rod member 10 and reinforcing rod members 12 to prevent shaking of the plurality of support members 11 or a simple L-shaped plate member. Since the overall shape is a L-shape, a pair of inverted U-shape viewed from the rear in a symmetrical structure, and together with the loading box (3) forms a box-shaped box body.

In addition, the lower end of the pivot structure 8, that is, the lower end of the L-shaped support member 11 is fixed in contact with the outside of the side wall of the loading box 3, and when the fixing state is released, a shape as shown in FIG. 4 is released. The torsion spring 13 rotates upward to open both sides of the loading box 3.

The torsion spring 13 includes a coil body 14 in which elastic force is accumulated, a fixed end portion 15 and a support end portion 16 formed at both ends of the coil body, and the fixed end portion 15 is a fixed member 7. It is fixed to, the support end 16 is to close the L-shaped support member 11 of the rotating structure 8, the coil body 14 side by side with a plurality of hinges 9 on both sides of the fixing member (7). The torsion spring 13 is fitted to the rod member 10 positioned, and is provided at least one at each of the two rotating structures 8, preferably at least at two locations of the respective rotating structures 8.

When the torsion spring 13 is pulled down by pulling the free end of the pivot structure 8 to the ground, elastic force is accumulated therein while the number of turns of the coil body 14 is increased (may be attenuated). When the external force acting on the structure 8 is removed, the restoring elastic force is applied to lift the upper structure by rotating the pivotal structure 8.

The outer cover of the pivot structure 8 is covered with a cover 17 is made of a fiber sheet is fixed, restraining or restraining the lower end of the pivot structure 8 is covered with the cover (3) A binding means 18 is provided, and the binding means is fixed to both ends of the cover 17 as shown, and the plurality of strings 19 and hook hooks 20 protruding from the outside of the loading box 3 are arranged. Although not shown in the figure, but may be used a fastening device having a conventional structure for binding the body and the lid of the stainless steel kitchen container.

Hereinafter, the operation of the present invention will be described in more detail.

When the strap 19 is normally tied to the hook loop 20 of the loading box, when the bag, for example, soil or sand, and other cargoes, the strap 19 is loosened for convenience of work. The elastic force of the torsion spring 13 acts so that the pivoting structure 8 connected to the fixing member 7 in the hinge 9 structure ascends and swings, so that both sides of the loading box 3 are opened. (FIGS. 6 and 7) Reference)

Accordingly, since the work is performed not only at the rear of the vehicle but also at both sides of the open loading box, the work of the cargo vehicle is performed quickly, and when the loading work is completed, the hook structure is pulled in the state where the pivot structure 8 is pulled down by pulling the string 19. 20) When the strap 19 is tied, the protective cover of the loading box is simply formed to prevent the falling of the loaded material on the road while the vehicle is running, and when the unloaded material is unloaded, the strap 19 is released. When the restraint state of the pivotal structure 8 is released, the pivotal structure 8 is pivoted upward to open both sides of the loading box so that the work of unloading the material can be easily and quickly performed.

Here, it may be considered to use an air cylinder or the like instead of the torsion spring 13 as an opening means of the rotational structure 8, but as described in the related art, the installation cost is high and the air brake of the vehicle is also considered. Since the air pressure must be used as the source of operation, energy loss is required due to the continuous operation of the vehicle engine, and the structure of the air hose is too complicated, so it is difficult to install and assemble the device unless it is a large-scale professional installer. Damage to the hose, such as a problem in the brake operation is not preferable in terms of safety.

The present invention as described above is attached to both sides of the holding member installed in the longitudinal direction of the loading box by rotating the hinge structure to open or close both sides of the loading box by a hinge, and release the restrained state of the loading structure of the loading box. The structure of the rotating structure is raised and rotated by the elastic restoring force of the torsion spring, so that both sides of the loading box can be opened and its structure is greatly simplified and easy to install. It is possible to assemble and install the product, greatly reducing installation time and cost, and it is possible to load and unload the material from the rear and both sides without the need for separate power according to the opening and closing of the cover, thereby improving convenience for loading and unloading. .
