BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand-carrying vehicle that can easily transport a long product, such as a rail, by itself.

[0002]

2. Description of the Related Art Conventionally, in order to transport a long product such as a rail at a factory or a work site, for example, a plurality of workers lift the long product by hand, and the center of gravity of the product is placed on a trolley. It is performed by pushing the cart after placing so that it is positioned.

[0005] However, this conventional transport means requires a plurality of workers to place a long product on a trolley, so that the work efficiency is poor, and it is necessary to lift the products by the hands of the workers. Some of them have to be troublesome. In addition, if the center of gravity of the long product is not accurately positioned on the trolley, there is a risk that it will fall during transportation.

[0004]

[Problem to be solved by the invention] The problem to be solved is that the conventional means for transporting a long product such as a rail requires a plurality of workers, so the work efficiency is poor, and the long product is handled by hand. The work is cumbersome because it needs to be lifted at the same time, and there is a risk of falling during transportation.

A description will be given with reference to the drawings. The hand truck according to the present invention is a carrier that mainly transports long products S such as building steel materials and rails by hand, and the load can be lightly loaded on the carrier by utilizing the leverage principle. Is bent downward in a circular arc shape to form a frame 1, a hook 2 for suspending a load at a front end and a handle 3 at a rear end, and a support point 1a provided between the front and rear ends to provide a motorcycle 5 through a vertical pole 11. At this time, the elongate load is positioned on the center line L of the chassis 6 so that the center of the load and the center of gravity of the carrier are at the same position and the carrier is stable. A holding piece 4 for holding the product load S is provided horizontally between the support point 1a of the frame 1 and the handle 3 so as to be located on the center line L of the motorcycle 5, And holding piece with a chain 14 Those configured to receive at two locations of the holding members 4 a hook.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a hand guided vehicle according to the present invention is shown in FIGS. This is a product that pushes and transports a long product (rail) S by hand, is curved in a downwardly arcuate shape, and is set between the middle point and the front end (a quarter of the total frame length from the front end). The frame 1 is formed by inclining the front part from the supporting point 1a in the lateral direction. The total length of the frame 1 is set to 2000 mm. (Instead of inclining the front part of the frame 1 in the horizontal direction when viewed in a plan view, the arm piece may be put on the lateral side of the linear frame as shown by the temporary line 1c in FIG. 2).

The support point 1 a of the frame 1 is fixed to the chassis 6 of the motorcycle 5 so that the front end of the frame 1 is located on the center line L of the motorcycle 5, off the center of the chassis 6. In addition, an upright 11 is interposed between the support point 1 a of the frame 1 and the chassis 6. Further, the motorcycle 5 is configured by connecting two wheels 7 each rotating around an axle 9 suspended between a pair of forks 8 by a chassis 6.

Further, a hook 2 for suspending the product S is provided at the front end of the frame 1, and a holding piece 4 for holding the product S is provided between the middle point and the rear end of the frame 1. It is provided in the lateral direction so as to be located on L. A handle 3 is provided at the rear end of the frame 1. Note that, in the present embodiment, the frame 1 is divided at a substantially intermediate portion and connected with the hinge 1b so that the frame 1 can be folded and stored.

[0009] The operation of the hand transport vehicle will be described in the case of transporting a long product S. First, the handle 3 is lifted and the frame 1 is rotated about the support point 1a (the two-wheeled vehicle 5) as a fulcrum, and its tip is brought close to the ground. Next, the wire 10 attached to the center of the product S is hooked on the hook 2 at the end of the frame 1, and then the handle 3 is pushed down. As a result, the frame 1 rotates about the support point 1a (the motorcycle 5) as a fulcrum, and its tip rises, whereby the product S is lifted. At this time, since the support point 1a is provided at a point 1/4 of the entire length of the frame from the front end, the product S can be easily lifted with a small force by the leverage principle. Therefore, the work can be performed alone.

In a state where the product S is lifted by the hooks 2, a portion of the product S behind the portion lifted by the hooks 2 is held by the holding pieces 4. At this time, when the center of gravity of the product S lifted by the hook 2 is in front of the hook 2 (when the product S is bent forward), the product S is positioned on the lower surface of the holding piece 4 and fixed by a chain. Conversely, when the center of gravity of the product S is behind the hook 2 (when the product S is bent backward), the product S is placed on the upper surface of the holding piece 4 and fixed with a chain as necessary. . The operation of moving the product S and fixing it to the holding piece 4 can be easily performed with a light force because the product S has already been lifted by the hook 2 and is in a suspended state. Therefore, the work can be performed alone.

Finally, with the product S lifted up with the hook 2 at the front end of the frame 1 and the holding piece 4 at the rear end, the handle 3 is pushed to transport the product S to the destination. Here, since the product S is held at the front and rear two places by the hook 2 and the holding piece 4, it is safely transported in a stable posture.

[0012] The hand-held carrier according to the present invention can be used not only for transporting a long product S, but also for transporting a non-long product S as shown in FIG. In particular, it is suitable for transporting a heavy product S.

[0013]

[Embodiment] The present invention relates to a transport vehicle that transports long products S, such as building steel materials and rails, by hand, and that the load can be lightly loaded on the transport vehicle by utilizing the leverage principle. A 34 mmφ pipe with a length of about 2 m is bent downward in an arc shape, and as a frame 1, a hook 2 for hanging a load is attached to a front end, a handle 3 is attached to a rear end, and a support point 1 a is distanced between the front end and the rear end. And attached to the chassis 6 of the motorcycle 5 via the uprights 11 at a ratio of about 1: 3.

At this time, the vertical column 11 is mounted so as to be shifted from the center of about 5 cm so that the long load comes on the center line L of the chassis 6. The center of load and the center of gravity of the transport vehicle are at the same place, and the vehicle is stabilized.

Further, the holding piece 4 for holding the product load S between the support point 1 a of the frame 1 and the handle 3. The load and the holding piece are tied up with a chain or the like so as to be positioned on the center line L of the motorcycle 5. The hook and the holding piece 4 to carry the load.

[0016]

[Effects of the Invention] The hand-carriage vehicle according to the present invention can perform the work of lifting and holding the product S with a small force, so that it can be easily conveyed by one person and work efficiency can be improved. Can be.

Further, since the product S is held at the front and rear two places by the hooks 2 and the holding pieces 4, the product S is transported in a stable posture, so that the product S does not drop during the transport, and work safety is improved. be able to.

There are two advantages of making the frame 1 in an arc shape. (A) The support point 1a of the frame 1 is the center of gravity of the carrier, and the lower the point, the better the stability. Welding 12 is simple. Straight pipes 21 and 21 require a reinforcing plate 23 and a weld 22 (see FIG. 6). (B) The shear stress on the pipe of the frame material is stronger in an arc shape than in a straight shape, that is, it is stronger against deflection.
