Further, the 1 st guide pin 530 installed on the connection block 520 is to be located at a boundary portion of the vertical portion and the horizontal portion of the main body 410 side guide groove 415 of the bracket 400 when the handle member 200 is lowered, and the 2 nd guide pins 540 installed on both side ends of the lower portion of the handle member 200 are to be brought into a state of being separated from the main body 410 side hooking groove 416 of the bracket 400.

At this time, by folding back in a state that the handle member 200 is pressed, the connecting block 520 is rotated simultaneously with the 1 st guide pin 530 as a rotation center, so that both lower ends of the handle member 200 pass through the side-entry grooves 433 of the guide plates 430 and are horizontally laid to the middle height of the body 410.

When the handle member 200 is pushed forward as shown in fig. 7 in a state where the handle member 200 is horizontally laid, both side ends of the handle member 200 are inserted into the rail grooves 310 and enter the storage state shown in fig. 1.

That is, both side ends of the handle member 200 are received (wrapped) in the rail grooves 310 of the recessed grooves 300 formed on both side ends of the thickness surface of the loading plate 100, so that not only can the appearance be more beautiful, but also a plurality of carts can be stably stacked and then transported and stored, and also articles having a width larger than the width of the loading plate 100 can be easily loaded and transported without being interfered by the handle member 200.

In addition, since the bracket 400 and the folder 500 for guiding the folding of the handle member 200 do not protrude to the upper portion of the loading plate 100, that is, the upper side surface of the bracket 400 and the upper side surface of the loading plate 100 are at the same height, it is possible to prevent the damage and breakage of the cart by preventing the cart from directly colliding with an external object during the traveling of the cart or during the storage and transportation of the cart, thereby improving the lifespan of the cart.

Therefore, the folding handle structure for a scooter according to the present invention is configured such that the brackets 400 mounted on both rear side ends of the loading plate 100 do not protrude to a height higher than the upper side surface of the loading plate 100 and the outer diameter of the lower end thereof can be stably maintained in a right angle state by the mutual engaging force between the brackets 400 and the folding pieces 500 when the handle members 200 horizontally stored (stored) inside the thickness portion of the loading plate 100 are taken out to be used upright by the guiding action of the brackets 400, so that the damage and breakage of the brackets 400 due to the direct collision with the external object can be prevented during the driving of the scooter or during the storage and transportation of the scooter, and the transportation and storage of the plurality of carts can be stably stacked, and the loading and transportation of the articles having a width larger than the width of the loading plate 220 can be easily performed without the interference of the handle members 200, and can prevent the connecting part from moving or being damaged when the plate trailer is pushed and pulled.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
