0001

[Industrial application field]

This invention relates to a trolley that can easily load cargo to be transported. be.

0002

[Conventional technology]

In conventional trolleys, there are A wheel is provided between the two frames, and the loading platform on which the cargo is to be loaded is fixed, and the It had a continuous handle.

0003

[Problem that the idea aims to solve]

However, with the above-mentioned carts, the loading platform is located at a higher position than the floor. In order to transport cargo placed on the floor, first load the cargo onto the loading platform. Lifting something heavy enough to be transported using a loading platform by yourself This is often difficult and requires several workers just to load the trolley. However, this was one of the causes of a significant decrease in work efficiency.

0004 In addition, in order to solve the above problems, for example, the height of the loading platform should be made almost the same as the floor. Assuming that the cart is configured at a This may cause inconveniences such as collisions.

[0005] Therefore, when transporting heavy loads, place the loads on pallets in advance. It can be transported by lifting the entire pallet up using a forklift, etc. However, it is usually not possible to work with a forklift, such as in relatively narrow spaces. In such a situation, transportation by trolley is necessary. The only way to transport it was by cart.

[0006] In view of the above points, the present invention has been developed to The cargo to be transported can be easily loaded onto the platform of the trolley by only the person operating the trolley. The purpose is to provide a trolley that can be used for various purposes.

[0007]

[Means to solve the problem]

In order to achieve the above purpose, the present invention is designed to In addition to installing wheels at the bottom of each frame, cargo should be loaded between the two frames. A loading platform is provided, and the surface is parallel to the loading platform and slightly above the top surface of the loading platform. Install several exposed rollers between the above two frames, and In a trolley with continuous handles, the wheels rolling on both frames are A movable member having a structure is provided on each of the frames, and A swing arm support part is provided in the swing arm support part, and the swing arm is swingably supported on the swing arm support part. Accordingly, a flat push-up plate portion is provided between the front ends of both swing arms, and an operating portion is provided between the rear ends. The structure was constructed by erecting the bridge.

[0008]

[Effect]

With the above configuration, the swinging arm is supported by the swinging arm support provided on the moving member. Therefore, it can be moved back and forth as the movable member moves back and forth. Since a push-up plate is installed at the front end of the swinging arm, the swinging of the swinging arm causes the The push-up plate part will move up and down, and the operating part shall be installed at the rear end of the swinging arm. , the swinging arm moves up and down in the opposite direction to the up and down movement of the push-up plate. Become.

[0009] Therefore, if the movable member is moved furthest forward, the push-up plate will be located in front of the front end of the truck. If the push-up plate is lowered while maintaining this state, the push-up plate will be attached to the cart. It can be lowered to the floor without being disturbed, and the push-up plate part is configured in a flat plate shape. Therefore, if the trolley is moved towards the cargo to be transported in this state, the push-up plate will can be inserted under the load, and the front part of the load can be placed on this push-up plate. It will be in a state where it exists.

0010 In this state, if you move the operating section provided at the rear end of the swinging member downward, the swinging arm will move. The push-up plate can be raised by swinging, raising the front part of the load above the height of the loading platform. It can also be pushed upward.

[0011] Since the movable members can move back and forth on the frame of the trolley, it is possible to If the cart is moved forward (relatively, the moving member moves backward on the frame), the push The position of the upper plate and the front part of the baggage on it does not change, and the cart is moved forward. The push-up plate and the front part of the load on it can be moved upward near the loading platform. If you move the push-up plate until it is located at is present on the loading platform.

0012 At this point, when lowering the push-up plate, place it on the loading platform between several rollers. If you set the roller surface to be slightly higher than the top surface of the loading platform, Therefore, the thin push-up plate is lowered to a position slightly lower than the roller surface. After that, the load can move on the rollers without being affected by the push-up plate. It will be possible to do so.

[0013] To move the load on this roller, the person operating the trolley pulls the top of the load toward you. Because the load moves on rollers, only the person operating it Therefore, the cargo can be easily loaded onto the platform of the trolley. It is something that can be done.

【Example】

Hereinafter, embodiments of the present invention will be described based on the drawings. As shown in FIG. 4, wheels 5 and 6 are provided at the lower part of the rear end, and a rod-shaped part is provided between the frame 1 and the frame 2. A loading platform 9 made up of materials 7 and 8 is provided, and rollers 10 and 11 parallel to the loading platform 9 are mounted on the loading platform. Wheels 12, 1 are installed between the frame 1 and the frame 2 and can roll on the frame 1. 3 and wheels 14 and 15 that can roll on the frame 2. A moving member 17 is provided, and swing arm supports 18 and 19 are provided on both moving members 16 and 17. At the same time, the swing arms 20 and 21 are swingable on both swing arm support parts 18 and 19. A flat push-up plate portion 22 is constructed at the front end of both swinging arms 20 and 21, and both swinging arms 20 and 21 are An operating section 23 is installed at the rear ends of the swinging arms 20 and 21, and the operating section 23 is installed at the rear ends of both frames 1 and 2. Hand push members 24, 25 and handles 26, 27 are provided at the tips thereof. .

[0015] The moving members 16, 17 are moved by rolling wheels 12, 13, 14, 15, respectively. The swinging arms 20 and 21 can be moved on both frames 1 and 2, and the swinging arms 20 and 21 are connected to the moving members 16 and 17. Since the swing arm supports 18 and 19 are pivotally supported by the swing shafts 28 and 29, If the movable members 16 and 17 are moved back and forth, the swinging arms 20 and 21 are also moved back and forth at the same time. move.

[0016] The swinging arms 20 and 21 swing around swinging shafts 28 and 29 as fulcrums. A push-up plate section 22 installed at the front end of 1 moves up and down as the swinging arms 20 and 21 swing. The operating section 23, which is movable and installed at the rear end of the swinging arm 21, responds to the swinging of the swinging arms 20 and 21. The push-up plate portion 22 moves up and down in the opposite direction.

[0017] Here, the swinging arms 20 and 21 are supported by springs 30 and 31 behind the swinging shafts 28 and 29. Since it is urged upward, the operating section 23 is moved upward and the push-up plate section 22 is pushed downward. A force is applied to swing in the direction of movement.

[0018] When loading the cargo 32, the moving member 17 is moved as shown in FIGS. 2 to 4. If the frame 2 is moved to the frontmost position and the push-up plate portion 22 is lowered, the push-up plate portion 22 can be lowered to the floor A ahead of the front roller 10.

[0019] At this time, the push-up plate portion 22 is configured in a flat plate shape, and the push-up plate portion 22 is biased by the spring 31. 2, the lower surface 33 of the push-up plate part 22 is tightly pressed against the floor surface A. I will wear it.

[0020] Therefore, while maintaining this state, the trolley body B is moved toward the cargo 32. As a result, the push-up plate portion 22 can be inserted between the cargo 32 and the floor surface A, and the As a result, the front part of the baggage 32 can be placed on the push-up plate part 22. (See Figure 2).

[0021] Next, the person operating the trolley body B lowers the operating section 23 by stepping on it with his or her foot. If it is moved in the direction, the swinging arm 21 swings and the push-up plate part 22 can be raised. The front part of the cargo 32 can be pushed up above the height of the cargo platform 9. Furthermore, since the moving member 17 can move backward on the frame 2, If the trolley body B is moved forward, the swinging arm 21, the push-up plate part 22 and the operation part 23 By maintaining each of them in the above state, the trolley body B is relatively 2 (see Figure 3).

[0022] At this time, the push-up plate section 22 is moved to a position higher than the surface of the roller 10. By doing so, when moving the truck body B, the push-up plate portion 22 will be moved by the rollers 10, etc. It will no longer come into contact with the object and impede movement.

[0023] Next, by removing the downward force on the operating part 23, the spring 31 is attached. Since the push-up plate portion 22 is given a downward force by the force, the push-up plate portion 22 is pushed up against the loading platform 9. This allows the front part of the load 32 to be lowered above the load platform 9. , and a part of the bottom of the load 32 is supported by the front roller 10. (See Figure 4).

[0024] The load 32 supported by the rollers 10 in the above manner is then transferred to the rollers 10. The person operating the trolley must be moved on top of the trolley 10. If the person pulls the top of the baggage 32 toward you, it can be easily moved, and the baggage 3 2 has moved to a certain extent above the cargo platform 9, the bottom surface of the cargo 32 is placed above the cargo platform 9. 9, and the load 32 is also supported by the rollers 11. This makes it easier to move.

[0025] Here, the surfaces of the rollers 10 and 11 are slightly higher than the upper surface of the loading platform 9. Since the push-up plate part 22 is provided so as to be , the push-up plate portion 22 will be at a position slightly lower than the surfaces of the rollers 10 and 11. The load 32 can be moved while being supported by the rollers 10 and 11. The push-up plate portion 22 does not affect the movement of the cargo 32 in any way. (See Figure 4).

[0026] Note that when placing the push-up plate portion 22 on the floor surface A or the loading platform 9, the push-up plate portion 22 is In order to keep it flat, for example, as shown in FIG. A support member is provided between the push-up plate holding portion 34 for connecting the swing arm support portion 18 and the swing arm support portion 18. 35 may be provided.

[0027] Further, as shown in FIG. 6, the top surface of the frame 1 is inclined from the front to the rear. If this is done, the moving member 16 will always have a force that tends to move in the backward direction. Therefore, when the push-up plate section 22 is moved upward to push up the cargo 32, the moving member As a result of 16 trying to retreat, the truck body (not shown in FIG. 6) moves relatively forward. Since the force of trying to This makes it easier to move the load (not shown in Figure 6) downwards, making it easier to carry out the work. It improves efficiency.

[0028] Furthermore, as shown in FIG. 7, when the load 32 is supported by the rollers 10, is the force α in the direction of rotating the roller 10 (in the direction of the arrow) due to the weight of the load 32 acts on the roller 10, and a component force β of the force α acts on the roller 10, and a component force γ of this force β acts on the roller 10. , a force is applied to move the cart body (not shown in FIG. 7) backwards, and the cargo 32 The roller 10 may slide outward from the trolley (not shown in FIG. 7). It is sufficient to use a ratchet 36 that can be rotated in only one direction. Although not shown, a normal wheel rotation stopper can be used to prevent the vehicle from rolling back. be.

[0029] In the examples, only two rollers and one type of each shape are described. However, it is natural from the purpose of this invention that these questions are not questioned.

[0030]

[Effect of the idea]

As described above, the present invention allows the person operating the trolley to use the operating section provided at the rear end of the swinging arm. By moving it downward, the swinging arm is swung and the push-up plate section is moved upward. Therefore, the front part of the cargo to be loaded onto the trolley can be moved by the push-up plate. A person who is able to push the cargo up to the loading platform of the trolley and who operates the trolley to lift the cargo on the loading platform The cargo can be loaded onto the trolley by pulling the cargo onto the trolley. When transporting goods from a trolley, only the person operating the trolley can move the cargo to be carried by the trolley. It can be easily loaded onto the loading platform.

[0031] The above operation unit is located near the rear of the truck because it is installed at the rear end of the swinging arm. However, the person operating the trolley can easily operate it by stretching his/her legs, and the operations are simple. Since all you have to do is press down on the operation part, the person who operates the trolley should start from the handle. There is no need to take your hands off, and you can use both hands to hold the trolley in place when operating the control section. Therefore, it is possible to avoid dangers caused by the tilting of the truck, etc.
