Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a unicycle that has been improved from a unicycle used as a handcart, which was used only for transportation, to be able to scoop up objects to be carried.

(Conventional technology) The present invention will be described in detail with reference to FIG.

FIG. 8 is a perspective view of a unicycle showing a conventional example of the present invention.

As shown in FIG. 8, the conventional unicycle 1 has wheels 3 on the underside of the platform 2 on which objects are placed, and a pair of armrests 5 for determining the direction of the wheels and supporting a certain amount of load. At the end of this arm 5, there is a handle 6 for operating the wheeled vehicle.
Further, at the rear of the loading platform 2, a pair of supports 8 for preventing the wheeled vehicle 1 from falling over was arranged in a state of protruding toward the running surface.

Such a wheeled vehicle 1 can stand upright with three-point support, with the wheels 3 and the pair of supports 8 in contact with the running surface. In this state, when the object to be transported is placed on the carrier 2 and the arm 5 is lifted up by gripping the handle 6, the pair of supports 8 are separated from the ground surface and the object can be moved by the wheels 3.

(Problems to be Solved by the Invention) According to the unicycle having such a configuration, since the loading platform 2 is on the wheels, each time when loading an object onto the loading platform,
They had to lift it onto the loading platform, which was a lot of work.9 When transporting dirt, fallen leaves, etc., it was necessary to scoop it up one by one with a shovel, etc., and then put it into the loading platform of a wheeled cart. Not only is it labor-intensive, but it also takes a long time to load even light items, resulting in extremely low work efficiency.

In addition, although the wheels are located under the loading platform, they are provided slightly in front of the loading platform to ensure a stable posture with pressure point support when the wheeled vehicle is erected. As a result, the center of gravity is at the rear, and when transporting heavy objects such as earth and sand, part of the load is applied to the hand holding the handle, requiring a force in the direction of lifting the arm 5. As a countermeasure, bands were attached to a pair of armrests and worn around the neck and shoulders, allowing the body to support the burden. In other words, conventional unicycles have the disadvantage that a load is constantly applied to the carrier in a direction that presses down on the carrier, making it difficult for the carrier to move and causing severe fatigue.

[Configuration of the Invention (Means for Solving the Problems) In order to solve the above problems, the present invention has the following configuration.

Wheels are provided at the rear of the loading platform, and the tip of the loading platform is -
It is placed so that it can come into contact with the running surface of the wheeled vehicle.

(Function) By grounding the tip of the loading platform, dirt, fallen leaves, etc. can be scooped into the loading platform without having to shovel them in.

The load of the object to be transported acts to raise the arm, and when the handle is grasped, a force is applied in the direction that the body floats.

(Example) Examples of the present invention will be described with reference to the drawings. 1 is a perspective view showing the unicycle of the present invention, FIG. 2 is a side view of FIG. 1, and FIG. 3 is an exploded perspective view of FIG. 1.

As shown in FIG. 1, the unicycle 10 of the present invention includes a dust pan-shaped loading platform 20, and an arm 30 that supports the loading platform and operates the unicycle.
and a wheel device 40 arranged behind the loading platform 20 and attached to the arm 30.

As shown in FIG. 2, this wheeled vehicle 10 is arranged such that the wheels are provided at the rear of the loading platform so that the tip of the loading platform 20 is in contact with the running surface of the unicycle.

Such a wheeled vehicle 10 will be further explained with reference to FIG.

The loading platform 20 on which objects to be transported is placed is a container body 24 in the shape of a dustpan with an open end 22 at one end, and a groove 25 and a notch 26 are provided around the container body 24. The groove 25 serves as a guide for attachment to the arm 30, and the notch 26 serves as a relief portion from which the arm 30 protrudes. This loading platform 20 is assumed to be a metal plate, although it depends on the type of the object to be transported, but if it is for transporting lightweight objects, it may be made of synthetic resin.

The arm 30 is made of a metal pipe or the like, and is formed by joining a pair of rods by welding or the like to form an arm 32, which is bent symmetrically with both ends moving away from each other. One of them is formed into a frame shape and serves as a loading platform support 34 to which the loading platform 2° is attached, and its tip is bent in the direction of ground contact to provide a support 35.

The other end is bent at right angles to the arm 32 to form a handle 38, and this handle is provided with a cover 39 for the purpose of slipping, etc., for easy grip.

The loading platform 20 and loading platform support 34 are attached at the open end 2 of the loading platform.
Groove 2 is placed around the loading platform so that 2 is the tip.
5 is fitted onto the rod of the loading platform holder 34 and attached by winding or welding.

The wheel device 40 consists of a wheel 42 and a wheel support 44. The diameter of the wheel varies depending on the size of the wheeled vehicle, but a relatively large diameter and wide tire will provide smoother smoothness. The wheel support 44 includes a cylindrical arm insertion part 45 that can be attached to the arm 32, and a pair of wheel fixing pieces 46 that are integrated with the arm insertion part and protrude from the arm insertion part. A hole 47 is provided at the tip of the wheel fixing piece, into which an axle 48 is inserted and the wheel 42 is rotatably attached.

In such a wheel device 40, the arm insertion portion 45 is inserted into and fixed to the arm 32 of the arm. This wheel support 44 is
It is fixed close to the rear of the loading platform support 34, and the wheeled vehicle 10 is kept upright by three-point support between the ground contact surface of the wheel 42 and a pair of supports 35 provided on the armrest 30.

Further, the tips of the pair of supports 35 and the tips of the open end 22 of the loading platform are set at the road plane and are kept at a height shown in FIG. is attached.

The state of use of the unicycle 10 constructed in this way will be explained with reference to FIGS. 4 to 7. FIGS. 4 to 7 are explanatory diagrams showing examples of use of the unicycle according to the present invention.

As shown in FIG. 4, when transporting with this wheeled vehicle 1.0, the height of the support 35 is set so that it almost touches the running surface 55, and the material 5o such as earth and fallen leaves is scooped up with the loading platform 20. Run and ride like this. Therefore, it is convenient if the tip of the support 35 is curved in a warped shape, since there is less resistance when the support 35 comes into contact with the running surface. Furthermore, when used in a place where the running surface is stable, operability is further improved by attaching a pulley or the like to the tip of the support.

If the object 50 cannot be scooped up at once, the operation shown in FIG. 4 is repeated several times to place as much object 50 as can be carried onto the loading platform 20.

When the object to be transported is placed on the loading platform 20, as shown in FIG. It floats up from the surface and loading is completed.

When loading is completed, as shown in FIG. 6, the axle 10 is moved backward a little, the direction is changed, and then the vehicle moves in the transport direction.

When unloading the transported object 50, as shown in FIG. You can slide down 50.

Although the description assumes that the objects to be transported are earth and sand, fallen leaves, etc., the present invention is not limited to these, and it is possible to transport various kinds of objects in the same way as conventional unicycles.

In this case, according to the unicycle 10 of the present invention, since the loading platform 20 is located on the running surface, the object 50 can be placed on the object 50 with less force without having to be completely lifted up in a sliding manner.

[Effects of the Invention] As explained above, according to the present invention, many effects can be obtained by arranging the loading platform so as to be in contact with the running surface.

In other words, depending on the type of object being transported, it is now possible to scoop it up without having to lift it onto a loading platform. In addition, even if the load is heavy, it can be slid onto the loading platform, and the load can now be placed more efficiently with less force. In other words, 1 more than before
The weight of each item has increased so that heavy objects can be carried.

Furthermore, when unloading the cargo, the cargo platform can be slid down while remaining in contact with the running surface, which reduces the impact on the cargo and allows for quiet unloading. Therefore, it is advantageous for handling items that are easily damaged.

By making the loading platform into a dust pan, scattered dirt, fallen leaves, etc. can be swept into the loading platform using a broom, making it possible to transport items in a clean condition without having to clean up afterwards. Ta.

Additionally, by sliding the loading platform, it can be used for shoveling snow, and heavy food waste containing moisture from the home can be easily transported over long distances, increasing the utility value of wheeled vehicles. I was able to do that. What's more, there is a loading platform and arms in front of and behind the wheel, which serves as a fulcrum, and when a load is placed on the arms, a force is exerted on the arms to lighten the body of the carrier, making it easier to move and easier for women and children to handle. I was able to get many benefits from using a unicycle.
