Description

[Detailed Description of the Invention] This invention relates to a transport cart that is easy to operate and has good steerability.

Conventionally, transport carts had two of their four wheels, either the front or the front.
Either one wheel is fixed and the other two wheels are swivel wheels like casters, or all four wheels are swivel wheels.
The former is good for moving forward and backward in a certain direction, but it is difficult to move diagonally or sideways, and has the disadvantage of being restricted in movement in narrow spaces.The latter can move in any direction, but the wheels Because there is no consistency between the direction and the direction of travel, in order to move in the desired direction, it is necessary to apply a force to direct the direction of travel and a force to move forward, which requires more than the operating technique and force required for normal travel. It has the drawback that it requires a lot of force, and it also has the drawback that it usually needs to be operated by a plurality of people, which hinders labor-saving.

The purpose of this invention is to eliminate the above-mentioned drawbacks, and to provide a transport trolley that is easy to operate, has good steering performance, has good work efficiency, and can reduce labor.

Hereinafter, embodiments of this invention will be described based on the drawings.

The first embodiment is shown in Figs. 1 to 3, in which casters 2 that can rotate 360 degrees are attached to three corners of a base plate 1, and the other corner can be rotated by applying an external force. A semi-fixed steering wheel 3 is provided, and an operating ring 4 is integrally fixed to the steering wheel 3.

To use this transport cart, place the material on the base plate 1 with the steering wheel 3 as the rear wheel, rotate the operating ring 4 by hand so that the steering wheel 3 faces in the desired direction, and then move the material onto the base plate 1. You can move it to the desired location by pressing .

A second embodiment is shown in FIGS. 4 to 6, in which casters 2a that can rotate 360 degrees are attached to three corners of the base plate 1a, and a steering wheel 3a is provided at the other corner. A gear wheel 4a is fixed to the steering wheel 3a,
A shaft 6a of a toothed wheel 5a that meshes with the toothed wheel 4a is supported by a load receiving guard 7a, and a handle 8a is attached to the upper end of the shaft 6a.

To use this carrier, the material is placed on the base plate 1a using the steering wheel 3a as the rear wheel, and the worker rotates the handle 8a while pushing the carrier to steer the material from the gear wheel 5a. It can be moved to a desired location by rotating the ring 3a to face the desired direction and then pushing the base plate 1a.

A third embodiment is shown in FIGS. 7 to 9, in which casters 2b that can rotate 360 degrees are attached to three corners of the base plate 1b, and a steering wheel 3b is provided at the other corner. A worm wheel 4b is attached to the steering wheel 3b.
is fixed to the other end of the shaft 6b of the worm 5b that engages with the worm wheel 4b.
A bevel gear 11b is attached that meshes with a bevel gear 10b at the tip of a shaft 9b having a handle 8b at its upper end.

To use this carrier, the material is placed on the base plate 1b using the steering wheel 3b as the front wheel, and the operator rotates the handle 8b while pushing the carrier to move the material from the bevel gear 10b to the bevel gear 11b. , the shaft 6b and the worm 5b, the worm wheel 4b is rotated, the steering wheel 3b is rotated to face in the desired direction, and the base plate 1b is pushed to move it to the desired location.

This invention has the above-mentioned configuration and usage mode, and since one of the four wheels is a steering wheel, the operator can simply push the transport cart in the direction of travel by pointing the steering wheel in the desired direction. You can easily move it to the desired location by pointing it diagonally and pushing it diagonally to move it diagonally, or sideways by pushing it sideways to move it sideways, so you can operate it by yourself. Therefore, it is possible to save labor during transportation work, and by turning the steering wheel diagonally and pushing it sideways, it performs a turning motion, making it easy to make fine movements in narrow spaces. It is easy to operate and has an excellent effect on improving work efficiency.

According to the configuration of the embodiment of this invention, the steering wheel can be operated while pushing the trolley, resulting in good operability, and the steering wheel as the front wheel has good steering performance when pushing the bed plate from behind. It has a certain effect.
