[Structure] On both sides of the luggage carrier 1, a mounting hole 3 arranged in the width direction of the luggage carrier 1 and a communication hole 4 communicating with the mounting hole 3 at right angles are provided. Assembling rods 7 are horizontally provided at both ends of the U-shaped handle 6, and the assembling rods 7 are inserted into and engaged with the mounting holes 3 to form through holes 8 provided on the circumferential side of the assembling rods 7. Are aligned with the mounting holes 3 and the support rods 9 are engaged with these to fit the handle 6
Maintain the standing condition of.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a handle folding device for a hand cart.

[0002]

[Prior art]

 Although various structures of the handle folding device for the hand truck have been proposed, the structure is generally complicated and the complexity of the folding operation cannot be denied.

The present invention has been devised for the purpose of providing an apparatus having a simple structure, and therefore a relatively low manufacturing cost.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides mounting holes arranged in the width direction of the loading platform on both sides of the loading platform, and communication holes that communicate with each other at right angles to the loading holes, and the horizontal direction is provided at both ends of the U-shaped handle. Of the support rod that is rotatably engaged with the mounting hole, and is inserted into the communication hole through the through hole provided on the peripheral side of the assembly rod so that the support rod can be inserted and removed from the outside. The structure is such that the front ends are engaged.

【Example】

 FIG. 1 shows an embodiment of a handle folding device for a hand truck according to the present invention. FIG. 1 is a sectional view of essential parts, FIG. 2 is a perspective view, FIG. 3 is a front view of a second embodiment, and FIG. It is a front view of a three example.

In the figure, reference numeral 1 denotes a loading platform, and mounting holes 3, 3 composed of supporting metal fittings 2, 2 are horizontally provided on both sides of a rear end of the loading platform 1 in a width direction of the loading platform 1, and the mounting holes 3, 3 are provided with communication holes 4 and 4 which communicate with each other in the vertical direction.

The support fitting 2 is formed by welding a flat plate and a tubular body to each other, and the mounting portion 5 is welded to the luggage carrier 1 to form the mounting hole 3 and the communication hole 4.

Reference numeral 6 is a handle, and the handle 6 is provided with assembling rods 7 and 7 in which a pipe is bent in a U-shape and horizontally arranged at both ends, and the assembling rod 7 is rotated to the attachment hole 3. A handle 6 is movably engaged to assemble the loading platform 1, and a through hole 8 that matches the communication hole 4 is provided on the peripheral side of the assembly rod 7 engaged with the mounting hole 3.

Reference numeral 9 is a support rod having one end attached to the other end of the chain 10 fixed to the carrier 1. The support rod 10 has an outer diameter width slightly narrower than the inner diameter widths of the communication hole 4 and the through hole 8. It is a thing.

Then, when the handle 6 is erected, the through hole 8 is arranged at a position corresponding to the communication hole 4, and when the support rod 10 is engaged with these holes 4 and 8 in this state, the handle 6 rotates. The fall down is prevented, and the handle 6 can be folded by pulling out the support rod 10 from the holes 4 and 8.

In the second embodiment shown in FIG. 3, both ends of the handle 6 are arranged in opposite directions to form the assembly rods 7, 7, whereas the assembly rods 7, 7 are opposite to each other. 4 is a modification of the second embodiment.

[0012]

[Effect of device]

 Since the present invention has the configuration as described above, it is possible to maintain the standing state of the handle or to fold it by simply attaching and detaching the supporting rod to the loading platform, and to provide an inexpensive product with a simple structure as a whole. Can be provided.
