During tunnel excavation work, etc., the inner diameter of the excavated tunnel is small, and workers may not be able to walk upright inside the tunnel. In such cases, workers are forced to walk with their heads bent and their hips bent, but when the road is long and the walking distance is long, this posture becomes very painful and can cause back pain. More people will sue. Furthermore, if workers walk along a long road in such an unreasonable position and then reach the face to work, their backs will get tired and their work will not progress, which is not good for occupational safety.

この考案は上記事情に鑑みてなされたもので、

Then, by arranging two such carts 2 and connecting the supports 8, 8 of the carts 2, 2 with two horizontal pipe-shaped handrail rods 3, 3, the desired handcart 1 can be obtained. It will be done. Furthermore, among the handrail rods 3, 3, the height of the upper handrail rod 3 (distance from the rail 4 to the handrail rod 3) is generally about 700 to 1000 mm, and if it is less than 700 mm, the position is too low and the posture is poor. If the height exceeds 1000 mm, the upper body will not be able to bend sufficiently and walking will become difficult.

Then, if you walk using this handcart 1,
Since the weight of the upper body can be applied to the handrail 3, there is no need to put pressure on the lower back even when bending down.
Your lower back won't get tired and you won't suffer from lower back pain or shoulder pain. Furthermore, when not in use, by lifting the handrail rod 3, the rear frame 10 rotates downward about the rotation pin 11, and the carts 2, 2 can be folded in half in the direction of travel. Not bulky,
Convenient for storage. Furthermore, if the wheels 5 and 6 are made of engineering plastic such as monomer cast nylon resin (MC nylon) or rubber, the overall weight of the handcart 1 can be reduced, making it easier to change directions, etc. The noisy metallic sound will no longer be emitted between the

Further, as shown in FIG. 4, it is also desirable to vary the length of the columns 8, 8 so that it is easy to use for both large and small workers. That is, the support column 8 is divided into a main pipe 8a and a sub pipe 8b, and the lower end of the sub pipe 8b is reduced in diameter and is inserted into the main pipe 8a. Further, an insertion hole 13 through which a stop pin 12 is inserted is formed in the upper end of the main pipe 8a, and height adjustment holes 14 in three stages are formed in the lower end of the sub pipe 8b. There is. Then, by moving the sub pipe 8b in the vertical direction and inserting the stop pin 12 into the arbitrary height adjustment hole 14 and the insertion hole 13, the length of the support column 8 is changed in three stages, and the handrail rod 3 height can be changed.

As explained above, the wheelbarrow of this invention is
A chassis that can be folded in two in the direction of travel of the front and rear wheels is constructed between the front and rear wheels, and a support is erected on this chassis to form one trolley, and these two trolleys are connected by a handrail rod that is built between the above-mentioned supports. It is constructed in a connected manner, and is designed to be walked by grasping and pushing the handrails. Therefore, the weight of the upper body can be applied to the handrail, and there is no need to put pressure on the lower back even when bending down, and the lower back does not get tired and does not cause back pain or shoulder pain.
This makes it suitable for walking on narrow roads where it is impossible to walk in an upright position. Also, if the wheels are made of plastic or rubber, they will be lighter and make less noise while walking. Furthermore, if the length of the column (height of the handrail lever) can be changed, it can be used by workers of any physique. Furthermore, if a basket is attached to the support or handrail rod and luggage, tools, etc. are put in it, it becomes easy and convenient to carry the luggage. Furthermore, according to the handcart of this invention, the front frame constituting the chassis has a front wheel axle attachment part that holds the front wheel and has a bifurcated tip on the front edge of the plate-shaped frame main part. The rear frame has a rear wheel axle attachment part with a bifurcated tip that holds and axles the rear wheel, which is also integrally attached to the rear edge of the plate-shaped frame main part. Since it is configured,
You can easily install the front or rear wheel by inserting the front or rear wheel into the bifurcated part of each axle and attaching it to the axle, and you can easily remove the wheel by performing the reverse operation. It has advantages such as easy assembly and easy maintenance.
