The configuration of the transport cart 10 in one embodiment of the present invention will be described.

  FIG. 1 shows a perspective view of a transport cart in one embodiment of the present invention. FIG. 2 shows a plan view of the transport cart in one embodiment of the present invention.

1-2 has a loading platform 20 on which an article can be placed, and four wheels 40 are provided on the lower surface of the loading platform 20. The loading platform 20 is made of synthetic resin, and is formed in a substantially rectangular shape having a long planar shape on one side.

Two receiving grooves 21 for inserting the non-slip stoppers 30 are formed on the upper surface of the loading platform 20, and one anti-slip stopper 30 is inserted into each of the receiving grooves 21. Further, on the upper surface of the loading platform 20, two take-out grooves 22 that are connected to the receiving groove 21 and into which a finger or the like is inserted to take out the anti-slip stopper 30 are formed. In this embodiment, there are two anti-slip stoppers 30, receiving grooves 21, and taking-out grooves 22, but any number of these may be provided as long as it is one or more.

  FIG. 3 shows a perspective view of the anti-slip stopper of the transport carriage in one embodiment of the present invention. FIG. 4 shows a plan view of the anti-slip stopper of the transport carriage in one embodiment of the present invention. FIG. 5 shows a side view of the anti-slip stopper of the transport carriage in one embodiment of the present invention. FIG. 6 is an enlarged AA cross-sectional view showing the relationship between the anti-slip stopper of the transport carriage and the cargo bed in one embodiment of the present invention. FIG. 7: shows perspective AA sectional drawing which shows the relationship between the non-slip stopper of a conveyance trolley | bogie in one Example of this invention, and a loading platform.

  The anti-slip stopper 30 shown in FIGS. 3 to 7 is made of an elastomer (made of synthetic resin elastomer or rubber), and has an annular ring shape and a reverse concave shape in cross section. A circular space formed at the center of the annular ring shape is for enclosing the wheel 40. The shape of the anti-slip stopper 30 is not limited to the present embodiment, and various shapes are conceivable. For example, a polygonal ring shape may be used instead of the annular ring shape. Furthermore, the shape of the anti-slip stopper 30 may be a polygon or a circle such as a triangle, a rectangle, a pentagon or a hexagon, and the center space may be a polygon or a circle such as a triangle, a rectangle, a pentagon or a hexagon. .

  The receiving groove 21 shown in FIGS. 6 to 7 is a groove for fitting the anti-slip stopper 30 and has an annular ring shape and a concave section. The shape of the receiving groove 21 is not limited as long as the slip stopper 30 can be inserted. For example, when the shape of the slip stopper 30 is a polygonal ring shape, the shape of the receiving groove 21 is a polygonal ring shape groove along the shape. By doing this, it is possible to ensure the function of inserting the anti-slip stopper.

FIG. 8 is a perspective view of the transport cart with the anti-slip stopper removed in the transport cart according to one embodiment of the present invention.

The take-out groove 22 shown in FIGS. 6 to 8 is a groove for inserting a finger or the like in order to remove the anti-slip stopper 30 fitted in the receiving groove 21. Further, the takeout groove 22 is connected to the receiving groove 21.

The anti-slip stopper 30 is formed such that the horizontal dimension of the cross section thereof is larger than the horizontal dimension of the cross section of the receiving groove 21 corresponding thereto (FIG. 6). Moreover, the cross section of the receiving groove 21 is formed in a concave shape, and the cross section of the anti-slip stopper 30 is formed in a reverse concave shape (FIGS. 6 and 7). Since the anti-slip stopper 30 and the receiving groove 21 are configured as described above, when the anti-slip stopper 30 is to be fitted into the receiving groove 21, the side wall portion 31 of the anti-slip stopper 30 extends inward from the receiving groove 21. Under the force of (for example, the x direction in FIG. 6), it is elastically deformed. As the reaction force, an elastic force is generated that the anti-slip stopper 30 presses the receiving groove 21, so that they are fitted together. Thereby, even when the article placed on the loading platform 20 comes into contact with the anti-slip stopper 30, the anti-slip stopper 30 is detached from the receiving groove 21, or the anti-slip stopper 30 fitted in the receiving groove 21. Can be prevented from “shaking”.

Next, two methods of using the anti-slip stopper 30 in one embodiment of the present invention will be described.

FIG. 9 shows a perspective view 1 in a state where an anti-slip stopper is used as a stopper in the transport carriage according to one embodiment of the present invention. FIG. 10 shows a perspective view 1 of a state in which the anti-slip stopper is used as a stopper in the transport carriage according to the embodiment of the present invention.

A method of using the anti-slip stopper 30 as an anti-slip function for preventing slippage of the article placed on the loading platform 20 will be described.

First, as shown in FIGS. 1 and 2, the anti-slip stopper 30 is inserted into the receiving groove 21. After that, by placing the article on the upper surface of the loading platform 20, the anti-slip stopper 30 can be used as an anti-slip function. Note that the top portion 32 of the anti-slip stopper 30 is formed so as to protrude from the upper surface of the loading platform 20 in order to bring the article placed on the anti-slip stopper 30 into contact with the anti-slip stopper 30. The protruding amount is preferably 1 mm.

Next, a method of using the non-slip stopper 30 as a stopper function for restricting the movement of the transport carriage 10 will be described.

As shown in FIGS. 1 and 2, when the anti-slip stopper 30 is fitted in the receiving groove 21, first put a finger or the like into the extraction groove 22, hook the anti-slip stopper 30 from below, and lift it upward. Then, the anti-slip stopper 30 is taken out from the receiving groove 21. Thereafter, the anti-slip stopper 30 is placed on the ground or the like, and the wheel 40 is placed in the central space of the anti-slip stopper 30. Thereby, since the wheel 40 is enclosed by the non-slip stopper 30, the movement of the wheel 40 is regulated. By using as described above, the anti-slip stopper 30 can be used as a stopper function.

When there are two anti-slip stoppers 30, it is preferable to place the anti-slip stoppers 30 so as to enclose the diagonal wheels 40 as shown in FIGS. 9 to 10. This is because the rotation of the transport cart 10 can be suppressed. In addition, although one anti-slip stopper 30 is effective as a stopper function, two or more are preferable for stopping the rotation of the transport carriage 10.

In addition to the annular ring shape and the polygonal ring shape, the shape of the non-slip stopper may be a semi-annular shape or a U-shaped shape (not shown). In the case of such a shape, the movement of the wheel can be regulated by installing an anti-slip stopper on at least two or more wheels. In any case, by placing a non-slip stopper around the wheel, the movement of the wheel can be restricted and the stopper function can be exhibited.

As described above, the transport cart according to the present invention can achieve the anti-slip function of the cargo bed and the stopper function of the wheel by one member called the anti-slip stopper, and thus is much more in terms of manufacturing cost than the conventional transport cart. To be advantageous.
