In the main body 1, a plurality of U-shaped horizontal rods 4 ... Are attached to the vertical rods 3 and 3 extending in parallel at regular intervals, and a reinforcing rod 5 is provided between the horizontal rods 4. , 5, and a mounting portion 6 formed in an inner shape that matches the contour of the gas cylinder, and a support portion 7 provided at the tip of the mounting portion 6 so that the bottom of the gas cylinder is hooked. The ends of a pair of arms 8a, 8a formed by bending one pipe material into a V shape at its center and extending both ends in parallel are used to support the vertical rods 3, 3 on the mounting portion 6 by the above-mentioned support. Part 7
Handle part 8 foldably connected near the end opposite to the side
And a gripping portion 8 extending in the longitudinal direction of the mounting portion 6 to be in a usable state, and an engagement / disengagement mechanism for releasing the usable state. The grip portion 8 is folded by rotating around the rotating shafts 11 and 11 so as to pass through the outside of the wheels 2a and 2a.

As shown in FIGS. 1 to 4, the handle portion 8 has a hook-shaped locking piece 9 having one side long and the other side short at each tip of the pair of arms 8a, 8a. , 9 are fixed to the short side, and inclined surfaces 10, 10 are provided at the tips of the long sides.
To form. The long sides of the locking pieces 9, 9 are foldably connected to the vertical rods 3, 3 of the mounting portion 6 by rotating shafts 11, 11. Further, the tip 8b of the V-shaped portion of the handle portion 8 has a clip (not shown) attached to the edge of the support portion 7 in order to prevent the handle portion 8 from swinging when the handle portion 8 is folded. ).

A pair of the engagement and disengagement mechanisms described above are provided on both sides of the main body 1, but since they have the same structure, only one of them will be described in the following description. FIG.
As clearly shown in FIG. 4, the engaging / disengaging mechanism is provided in the vicinity of the tip of the locking piece 9 and the tip of the vertical rod 3 at a predetermined distance from the rotary shaft 11 in the vertical rod 3, and the locking piece is provided. An engagement / disengagement tool 12 having a distal end that can be detachably locked, and a handle portion 8 that is linked to the engagement / disengagement tool 12 and that can be operated to disengage the locking piece 9.
And the operating member 13 attached to the.

As clearly shown in FIGS. 3 and 4, the engaging / disengaging tool 12 has a pair of slits 14, 14 extending in the vertical direction, which has a substantially U-shaped cross section with one side open in the upper direction and one side in the vertical direction. A base body having a space formed between each outer wall 15 and inner wall 16 and the slits 14, 14 arranged at both ends in the space.
To the slide shaft 17 movably inserted into the operation member 1
A connecting body 19 for connecting the wire 18 extended from 3
A slider 20 integrally provided with the outer wall 1
5, and the tension springs 22 and 22 are provided, one end of which is hooked on the projecting pieces 21 and 21 projecting outward from the upper portion of the inner wall 16 and the other end of which is hooked on the both ends of the slide shaft 17. The slider 2
0 has a fixed shaft 23 for fixing the wire 18 inside the connecting body 19, and a window portion 24 for pulling out the end of the wire 18 on the front side of the connecting body 19. In this way, the slider 20 is pulled upward by the tension springs 22 and 22 applied to both ends of the slide shaft 17,
It is always in contact with the upper ends of the slits 14, 14.

The operating member 13 is constructed by supporting the cock 25 so that it can be pushed up by a support member of the arm 8a which is fixed at a position where an operator can easily operate, and the free end of the cock 25 is held together with the handle portion 8 by hand. The slider 20 of the engaging / disconnecting device 12 connected by the wire 18 is pulled down against the urging force of the tension springs 22 and 22 by gripping and pushing down. The wire 18 is covered by a tube so as to be movable.

In FIGS. 3 and 4, reference numeral 26 is a wire 1.
A pipe body provided at the tube end of No. 8 for smoothly transmitting the operation of the wire 18 to the slider 20. Further, in FIGS. 1 to 3, reference numeral 27 is a band for holding the wire 18. Further, in FIG. 4, reference numeral 28 indicates
It is a through hole for passing an extra portion of the tip of the wire 18.

Next, a method of using the hand truck for transportation of the above embodiment will be described. When not in use, operation member 1
By gripping the cocks 25 and 25 of the screws 3 and 13 together with the arms 8a and 8a, the sliders 20 and 20 are pulled down via the wires 18 and 18 and the locking pieces 9 and 9 and the slide shafts 17 and 17 are locked. The handle portion 8 is released and the handle portion 8 is folded with respect to the mounting portion 6. Further, in order to extend the grip portion 8 to the usable state, the grip portion 8 in the folded state is raised and the slide shafts 17, 17 are pushed by the inclined surfaces 10, 10 of the locking pieces 9, 9 to pull the tension spring. 22, 22, 2
While sliding the surfaces of the slide shafts 17, 17 on the inclined surfaces 10, 10 against the urging force of the sliders 22, 22,
Push 20 down. Then, when the respective tips of the locking pieces 9, 9 pass over the slide shafts 17, 17, the slider 2
Nos. 0 and 20 return to the original positions of the upper ends of the slits 14 and 14 due to the biasing force of the tension springs 22, 22, 22 and 22, so that the locking pieces 9 and 9 are locked to the slide shafts 17 and 17 to engage and disengage. The grips 8 are fixed in the gaps of the tools 12, 12 and the grip portion 8 is in a displaceable state, that is, the transport handcar is ready for use.

As described above, in the carrying handcar of the above embodiment, since the grip portion 8 can be folded with respect to the mounting portion 6, it can be made compact when not in use and can be used for truck delivery of gas cylinders, etc. There is an advantage that loading is easy and convenient, and there is an advantage that folding and unfolding operations are easy.

The present invention is not limited to the above-mentioned embodiment. For example, the mounting portion 6 is not formed for a gas cylinder but is formed so that a plurality of bottle cases can be stacked. Good. Further, the engagement / disengagement mechanism may be changed to a mechanism using another member instead of the cock 25 and the wire 18 as long as it can actuate the engagement / disengagement tool 12 as in the above embodiment. . Further, the locking piece 9 has an inclined surface 10
Need not be provided. Further, the folding direction of the handle 8 may be opposite to that of the above-described embodiment so as to pass through the side opposite to the wheels 2a, 2a. Furthermore, the auxiliary wheels 2b, 2
b may not be provided.

[0022]
