Description

Auto covering for cargo carrying box

The present invention relates to an automatic cover for a vehicle loading box, and more particularly, to an automatic cover for a vehicle loading box installed in a vehicle loading box of a freight vehicle and capable of automatically opening and closing.

In Korea, it is legally stipulated that when loading cargo on vehicles, especially vans, appropriate measures such as covering should be taken. In other words, pursuant to Article 39 of the Road Traffic Act (Method and Restriction of Riding or Loading), "Every driver of a car is required to ensure that the cargo is securely fixed, such as by covering or tying the cargo to prevent it from falling while driving. It must be done. " If this is violated, fines and penalties will be imposed.

In particular, by opening and closing both sides and the rear in the same structure as the top car, the load box can be used for various purposes.

In addition, the transportation of the dump truck must not only interfere with road traffic due to the falling of a transported object away from the dump truck's loading box, etc., but also affects the neighboring driving vehicles. If you do, you must install a cover on the top of the loading tray.

The cover of all conventional freighter stacks is roughly classified into the following three categories:

First, as a wing body, it is a cover type that moves up and down like an eagle wing, and it is made of steel and is made of a hydraulic cylinder, so the rear door is made of a casement type, and has a wide operating radius, which makes it difficult to use in a narrow space and has a high installation cost.

Secondly, it is possible to open the side door or the rear door by completely closing it with iron plate and iron with the top car, and there is a disadvantage that the loading and unloading of the load is inconvenient and the forklift cannot be used.

Third, the pipe is bent in an arc shape with a cover car (aka, Horocha) to install several vertically and covered with cloth, so that the side cannot be opened and closed by opening and closing the pipe. There are many problems.

In the case of opening the side of the freighter, the conventional cover as described above may cause a safety accident when the entire side is raised to the upper side to open it, which may cause a safety accident, and is affected by surrounding topographical features such as electric wires. There have been many studies to solve this problem because there is an uneconomic closing that causes a large load to the motor and requires an unnecessarily large capacity motor because the load is applied to the rotating shaft due to the rotation of a large radius.

For example, in the Korean Utility Model Publication No. 20-1993-0025409, in the loading box of a freight vehicle with a plurality of metal plates attached and reinforced to the side frame and back frame of the loading box of the freight vehicle, , Pipes with both ends open on the upper surface of the body in which the rollers mounted and driven are mounted on the "I" section steel and the "I" section steel formed on both side frames of the loading box, and inserted into the pipe for height adjustment Disclosed is a load box cover device for a freight vehicle, characterized in that it is made as a cover holder of a predetermined shape.

Publication No. 97-49397 is installed on the side of the loading box of the dump truck so that the frame is rotatably mounted so that the support rod is integrated into the pivot shaft, and the wire connected to one end of the support rod and the cover connected to the other side of the wire It relates to an automatic cover of the loading box of the dump truck configured to open and close the loading box cover of the dump truck by controlling the rotating means so that the wire and the cover connected to the wire are wound or released as the support rod rotates by connecting.

The publication No. 94-786 discloses a turnover cover for dump trucks, characterized in that a tent is connected to a motor and an air cylinder mechanically installed outside the loading box and a switch is installed inside the driver's seat to open and close the loading box by operating the switch. It is about the device.

No. 97-1092 uses hydraulic or electric power of the vehicle itself to connect hydraulic and electric motors to the cover line reduction shaft, and then connects the lines attached to the cover and rollers to both separator holes and rotates the hydraulic and electric motors. An automatic cover opening and closing device for a vehicle loading box is described, which is characterized in that the loading box is opened and closed in the driver's seat by an automatic winding and unwinding action along a cover supporting groove by reverse rotation or stop.

In the domestic registration utility model registration number 20-0368354, a loading frame is formed on the lower part and a loading box is installed on the upper part, and in the dump type loading box having a structure capable of elevating the loading box by the action of a hydraulic cylinder, the loading box is The dump-type loading and unloading container is made of upper and lower loading boxes, and the upper and lower loading boxes are configured to be separated and combined by connecting ports so that loading and transporting of heavy objects by the lower loading box and loading and transporting of grain combined with the upper loading box are performed. This is disclosed.

However, there is still a need for the development of an automatic cover for a vehicle loading box that can be installed on a vehicle loading box of a freight car to automatically open and close, and in particular, to facilitate loading and unloading of freight using a forklift.

An object of the present invention is to provide an automatic cover for a vehicle loading box that can be automatically opened and closed when installed in a vehicle loading box of a freight vehicle.

In addition, as shown in FIG. 4, a plurality of belt guides 121 are fixed to the inner surface of the lid 12. The belt guide 121 secures the belt 122 to the inside of the cover 12, preferably the cover 12, but functions to make the belt 122 slidably fixed, thereby using the belt 122 to rotate. It is possible to open and close the lid 12 by winding it up. That is, the belt 122 is slidably fixed between the cover 12 and the plurality of belt guides 121 and the cover 12. One end of the belt 122 is detachably fixed to a rotating shaft that is rotatably fixed to the top of the frame, and the other end of the belt 122 is integrally fixed to the lower end of the cover 12, and the rotating shaft is loaded (11 ) Extends in the front-rear direction and is fixed to be rotatable, so that the operation of winding the belt 122 by rotation in one direction of the rotation axis is possible, and the operation of unwinding the belt 122 by rotation of the rotation axis in the other direction It is possible.

As shown in Fig. 6, the belt 122 may be detachably fixed to the rotating shaft. As a non-limiting example, description will be given based on fixing one end of the belt 122 to the first rotating shaft 23 as follows. That is, a groove 231 is formed in the first rotation shaft 23, and a wide groove, that is, a wide groove and a narrow groove, that is, a narrow groove, is formed to connect the wide groove and the narrow groove, The end of the belt 122 to be fixed to the first rotating shaft 23 is formed as a thick end 123. At this time, the thickness of the thick end portion 123 of the belt 122 is thinner than the wide groove of the groove 231 formed in the first rotating shaft 23, and thicker than the narrow groove, so that it can be drawn in and out through the wide groove. , It is not possible to enter or withdraw through the narrow groove. Accordingly, after the thick end portion 123 of the belt 122 is pulled through the wide groove of the first rotating shaft 23, when the thick end portion 123 of the belt 122 is moved toward the narrow groove in the pulled state, the belt The thick end portion 123 of 122 cannot be withdrawn through the narrow groove, and thus the belt 122 is fixed to the first rotating shaft 23. In this state, when the first rotation shaft 23 is rotated in one direction, the belt 122 can be wound. On the contrary, when the first rotation shaft 23 is rotated in the other direction, the wound belt 122 can be released. The same may be applied to the second rotational axis 24 and the third rotational axis 25 and / or similarly.

The lid 12 is supported by a frame. 4, the frame is fixed on the loading box 11, it may be composed of a horizontal frame 21 and the vertical frame 22. In FIG. 4, the cover 12 is removed to expose the frame. Typically, the frame and the lid 12 supported by the frame preferably has a shape that covers the loading box 11, and as a non-limiting example, the frame has a shape of "∩", which is an inverted shape of the letter "U". In particular, it may be desirable to make the upper surface flat relative to the loading box 11. The frame is fixed to the transverse frame 21 to be extended to the left and right directions in the loading box 11, and the transverse frame 21 is fixed to the transverse frame 21 by the longitudinal frame extending in the longitudinal direction of the loading box 11 This solid mechanical assembly can be achieved. The frame may be made of ordinary iron, and preferably made of rod-shaped steel or C-shaped steel.

1 and 2, the rotating shaft is rotatably fixed to the frame, and as a non-limiting example, a drive box including a driving means such as a geared motor, that is, a combination of an electric motor and a reduction gear device as one. It is driven by (13). The rotating shaft may be plural. As a non-limiting example, the automatic cover 10 for a vehicle loading box according to the present invention includes four rotating shafts of the first rotating shaft 23, the second rotating shaft 24, the third rotating shaft 25, and the fourth rotating shaft 31. It can contain.

A weight bar 124 may be fixed to the bottom of each of the lid 12 covering the left and right sides of the loading box 11 and the lid 12 covering the rear. The weight bar 124 may help to close the lid 12 by pulling the lid 12 toward the gravitational direction, that is, the loading box 11. The weight bar 124 is preferably fixed to the inner side of the cover 12, forming a cut-out part 126 partially incising the lower part of the cover 12, and using this cut-out part 126, the weight bar 124 The weight bar 124 can be fixed to the lower end of the cover 12 by wrapping it. In addition, as shown in Figure 5, by exposing a portion of the end portion of the weight bar 124 to the outside of the incision 126 of the cover 12 to form a hook portion 125, the weight to the rod holder 211 described later The rod 124 can be easily caught.

In addition, the frame is fixed to the rod hanger 211 is variably fixed, one end of the elastic body 212 is fixed to the rod hanger opening 211 and the other end of the elastic body 212 is loaded (11) or frame. You can. By such a 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 in the rod hanger 211, and the rotating shaft In the case of further rotating, the weight bar 124 must be moved upward, and at this time, the pulling force of the elastic body 212 is overcome because the rod hook 211 is fixed by the elastic body 212, and further upwards. In order to be able to move and, on the contrary, when the rotating shaft is rotated in reverse, it is possible to move downward, that is, toward the loading box 11 with a combination of the weight of the weight bar 124 and the pulling force of the elastic body 212. The downward movement of the lid 12 by the action of the elastic body 212 is a weight bar in such a flat portion, especially when the top surface is flat with respect to the lid 12 and the frame 11. Even if the lowering of the cover 12 by the 124 is difficult or impossible, it is possible to make it possible to move by the pulling force of the elastic body 212. The elastic body can be used as long as it is stretchable, but may 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 be preferably accommodated in the protective tube 213 and thus elastically fixed and accommodated in the protective tube 213. The protective tube 213 may be fixed to the frame. The protective tube 213 serves to protect the elastic body 212 and guide the elastic body 212 during the elastic action of the elastic body 212. More preferably, the upper portion of the protective tube 213 may further include a guide portion 214 for guiding the progress and bending of the elastic body 212. Particularly, the guide portion 214 moves the elastic body 212 when the elastic body 212 is stretched and extended, in particular, when the elastic body 212 progresses from the vertical portion of the frame to the horizontal portion or vice versa. By supporting it, it is possible to enable the elastic body 212 to easily perform expansion and contraction.

Accordingly, by the above-described configuration, as shown in FIGS. 7 to 9, it is possible to open and close the operation of the cover 12, which will be described below with reference to the drawings. The following description is based on opening and closing the left-side cover 12 based on FIG. 1, but it may also be the same and / or similar to opening and closing the right-side cover 12.

As shown in FIG. 7, when the belt 122 is wound by rotating the first rotation shaft 23 in one direction, the belt 122 is fixed only to the lower end of the cover 12 and the belt 122 in the rest Since the and the cover 12 are not fixed with respect to each other, the cover 12 is pulled up from the bottom, and the cover 12 is partially folded and rises. Particularly, 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 rotation 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 cover 12 is caught by the rod hanger 211, and the first rotation shaft When the 23 is continuously rotated in the same direction, the cover 12 may be pulled up while continuing to be folded over the vertical portion to the horizontal portion. By this operation, the lid 12 may be opened. 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 the belt 122 and the cover 12 vertically accordingly The transition in the direction and / or the horizontal direction can be facilitated. As shown in "A" in Fig. 8, when the elastic body 212 made of rubber having a rectangular cross section is used, as well as shown in "B" in Fig. 8, the elastic body is made of a coil spring having a circular cross section. Even when 212 is used, it is possible to facilitate the opening of the lid 12 by enabling the extension action to facilitate the transition from the vertical direction to the horizontal direction of the elastic body 212.

Conversely, when the cover 12 is to be closed, as shown in FIG. 9, it can be automatically performed by rotating the first rotation shaft 23 in a direction opposite to the above-described direction. At this time, in the horizontal part, although the descent by gravity by the weight bar 124 cannot be made, it moves through the horizontal direction to the vertical direction by the pulling force of the elastic body 212 connected to the rod hanger 211 as described above. When the first rotating shaft 23 is continuously rotated in the same direction, the cover 12 may be continuously lowered by adding gravity help by the weight bar 124. In this case as well and / or similar to the above, it is possible to facilitate the closing of the lid 12 by enabling a contraction action that facilitates the movement of the elastic body 212 from the horizontal direction to the vertical direction.

This can also be applied to the second rotating shaft 24 in the same and / or similar way.

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

Therefore, the automatic cover 10 for the vehicle loading box according to the present invention is made of steel in a cover type that moves up and down like an eagle wing, such as a wing body, and is made of a hydraulic cylinder. This problem can be solved, it is also possible to solve the disadvantages of being completely sealed with a steel plate and a steel plate, such as a top car, to open a side door or a rear door, inconvenient loading and unloading of a load, and unable to use a forklift truck.

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 automatic opening and closing of the cover 12.

In the above, the present invention has been described in detail only with respect to the described embodiments, but it is apparent to those skilled in the art that various modifications and variations are possible within the scope of the technical idea of the present invention, and it is natural that such modifications and modifications belong to the appended claims.
