The weight rod 124 can help pull the cover 12 in the direction of gravity, that is, toward the loading box 11, to keep the cover 12 closed. The weight rod 124 is preferably fixed to the inside of the lid 12, to form an incision 126 in which a portion of the lower end of the lid 12 is cut and the weight rod 124 with the incision 126. By wrapping the weight bar 124 can be fixed to the bottom of the cover (12). In addition, as shown in FIG. 5, a portion of the end of the weight rod 124 is exposed to the outside of the cutout 126 of the lid 12 to form the hook portion 125, thereby forming a weight on the rod hanger 211 described later. The rod 124 can be easily caught.

In addition, the rod hanger 211 is variably fixed to the frame, one end of the elastic body 212 is fixed to the rod hanger 211 and the other end of the elastic body 212 to be loaded 11 or the frame. Can be. By this configuration, when the rotating shaft is rotated in one direction so that the weight rod 124 is moved upwardly, that is, away from the loading box 11, the weight rod 124 can be caught by the rod hanger 211, the rotating shaft When rotating more, the weight rod 124 should be moved further upwards, at this time because the rod hanger 211 is fixed by the elastic body 212 to overcome the pulling force of the elastic body 212, further upwards When the rotating shaft is reversely rotated, the weight of the weight rod 124 and the pulling force of the elastic body 212 can be moved downward, that is, toward the loading box 11. The downward movement of the cover 12 by the action of the elastic body 212 is particularly carried out by the weight rod (in this flat part) when the upper surface is flat with respect to the cover 11 and the loading box 11 Even if the lowering of the cover 12 by the 124 is difficult or impossible, it may be possible to move by the pulling force of the elastic body 212. The elastic body may be any stretchable material, but may preferably be a rubber band having a rectangular cross section or a coil spring having a circular cross section.

As shown in FIGS. 7 to 9, the elastic body 212 may preferably be accommodated in the protective tube 213, and thus may be elastically fixed and accommodated in the protective tube 213. The protective tube 213 may be fixed to the frame. The protective tube 213 protects the elastic body 212 and functions to guide the elastic body 212 when the elastic body 212 is stretched. More preferably, the upper end portion of the protective tube 213 may further include a guide portion 214 for guiding the progress and bending of the elastic body 212. In particular, the guide part 214 moves the elastic body 212 when the elastic body 212 is stretched and moves in the direction of the elastic body 212, in particular, from the vertical portion of the frame to the horizontal portion or vice versa. The elastic body 212 can be easily supported to perform stretching.

Therefore, by the configuration as described above, as shown in Figures 7 to 9, it becomes possible to open and close the cover 12, this will be described with reference to the drawings as follows. The following description is based on opening and closing the left side cover 12 with reference to FIG. 1, which may also be the same and / or similar to opening and closing the right side cover 12.

As shown in FIG. 7, when the first rotation shaft 23 is rotated in one direction to wind the belt 122, the belt 122 is only fixed to the lower end of the lid 12 and the belt 122 is rested. Since the lid 12 and the lid 12 are not fixed to each other, the lid 12 is pulled upward from below, and is lifted while the lid 12 is partially folded. In particular, due to the presence of a plurality of belt guides 121 integrally fixed to the inner surface of the cover 12, the cover 12 of the portion between the belt guide 121 and the belt guide 121 is folded on the basis of them. do.

When the first rotary shaft 23 is continuously rotated in the same direction, as shown in FIG. 8, the weight rod 124 fixed to the lower end of the lid 12 is caught by the rod hanger 211, and the first rotary shaft In the case where the 23 is continuously rotated in the same direction, the cover 12 can be pulled up while being continuously folded over the vertical portion to the horizontal portion. By this operation, the cover 12 may be in an open state. In particular, as shown in Figure 8, with the help of the protective tube 213 and the guide portion 214 of the protective tube 213, the elastic action of the elastic body 212 and thus the vertical of the belt 122 and the cover 12 The transition to the direction and / or the horizontal direction can be facilitated. As shown in " A " of FIG. 8, the elastic body 212 made of rubber having a rectangular cross section is used as well as the elastic body of coil spring having a circular cross section as shown in " B " Even when the 212 is used, the opening of the lid 12 can be facilitated by enabling the elongate action to facilitate the transition of the elastic body 212 from the vertical direction to the horizontal direction.

On the contrary, in the case where the lid 12 is to be closed, as shown in FIG. 9, it can be automatically performed by rotating the first rotation shaft 23 in the opposite direction to the above-described direction. At this time, in the horizontal portion, even if it can not be lowered by gravity by the weight rod 124 is moved to the vertical direction through the horizontal direction by the pulling force of the elastic body 212 connected to the rod hanger 211 as described above If the first rotary shaft 23 is continuously rotated in the same direction, the cover 12 can be continuously lowered by the weight rod 124 with the aid of gravity. In this case as well, and similarly to the above, the closing of the lid 12 can be facilitated by enabling the contracting action of the elastic body 212 to be easily shifted from the horizontal direction to the vertical direction.

This may be applied in the same and / or similar manner to the second axis of rotation 24.

Primarily, since the front is blocked by the vehicle's boarding portion, the cover 12 can cover all of the cargo loaded in the stack 11 by enclosing the left and right sides and the rear three sides, and according to the present invention, the right and left sides are covered. Since it can cover all up to the top by the covering operation, in the rear, it can be in a state that can cover all the cargo simply by moving only in the vertical direction without moving in the vertical direction, that is, in the horizontal direction.

Accordingly, the vehicle cover automatic cover 10 according to the present invention is made of a hydraulic cylinder made of steel in the cover type moving up and down like an eagle wing, such as a wing body is used in a narrow space because the rear door is made of a hinged type This difficult problem can be solved, and the side door or the rear door can be opened with the steel plate and the steel plate completely sealed like the top car, and the loading and unloading of the load is inconvenient, and the forklift cannot be used.

In addition, for convenience of operation, as shown in FIG. 1, the control box 14 may be electrically connected to the drive box 13 to facilitate the automatic opening and closing of the cover 12.

Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention, and such modifications and modifications are within the scope of the appended claims.
