Description

[Detailed description of the invention] The present invention has wheels on each of the front, rear, left and right sides of a base panel, and one side panel and front and rear panels are erected from the base panel, and can be opened and closed between the other ends of the front and rear panels. The present invention relates to a transportation trolley provided with a panel on the other side.

Such transportation trolleys are used, for example, to transport parcels at post offices and department stores. Here, since the top surface of the transportation trolley is open, articles such as parcels and parcels can be easily placed therein. On the other hand, since the top surface is open, there is a risk that the item may fall off due to vibration during transportation or be stolen.

In the present invention, rails in the left and right directions are attached to the upper ends of the front and rear panels, and a foldable upper panel is provided, one end of which is fixed to one end of the rail, and a roller attached to a folding shaft is installed inside the rail. The present invention proposes a transportation trolley that is placed alternately on the rails. With this configuration, articles can be easily loaded by folding the top panel and opening the top surface. By expanding and closing the top surface, it is possible to prevent items from falling off or being stolen.

Hereinafter, one embodiment of the present invention will be described based on the drawings. In Figures 1 and 2, 1 is the base panel, with a pair of left and right free wheels (caster wheels) in the front.
2, and a pair of left and right fixed wheels 3 at the rear.
has. One side panel 4, front panel 5, and rear panel 6 are erected from the base panel 1, and one side panel 4, front panel 5, and rear panel 6
The side edges of the two are connected by joint brackets 7, respectively. Furthermore, the other side panel 8 which can be opened and closed is provided between the other sides of the front and rear panels 5 and 6. The other side panel 8 is attached to the other side edge of the front and rear panels 5, 6 via a hinge 9, and is divided into upper and lower parts, each of which has double doors. 10 is a stopper, and 11 is a locking tool. As shown in FIGS. 1 to 9, left and right rails 12A and 12B are installed inside the upper ends of the front and rear panels 5 and 6, respectively. These rails 12A, 12B have a U-shaped cross section, and are installed with the open portion thereof on the inside. Reference numeral 13 denotes a folding type upper panel, which includes a plurality of folding shafts 14 (five in this embodiment) arranged in parallel in the left and right direction in the front-back direction, a large number of links 15 connected by these folding shafts 14, and these links 15. Each folding shaft 14 has rollers 17A and 17B at both ends, respectively.
is installed. One end of the rollers 17A, 17B is located within the rails 12A, 12B, and the fixing devices (bolts/nuts) 18A, 1
It is fixed by 8B. remaining roller 17
A and 17B are inside rails 12A and 12B and rail 1
They are located alternately on 2A and 12B. That is, the second and fourth rollers 17A, 17B are located on the rails 12A, 12B. A handle 19 for manual operation is provided at the other end of the upper panel 13. A fixed stopper 20 is provided near one end on one rail 12A, and a rotating lever 23 is attached to the other front end of the upper panel 13 via a bracket 21 and a shaft 22.

1 to 5 show a state in which the upper panel 13 is unfolded and the upper surface is closed. At this time, the rotation lever 23 is rotated into the upper panel 13. To open the top surface in this state, first move the top panel 13 to one side via the handle 19. As a result, the upper panel 13 is folded in the horizontal direction as shown in FIG.
Since B is located within the rails 12A and 12B, folding is performed smoothly and reliably. After folding, the rotary lever 23 is rotated to lock it to the fixed stopper 20. As a result, even if the handle 19 is released, the upper panel 13 will not return. When opening the upper panel 13 again, it is sufficient to first rotate the rotary lever 23 to release it from the fixed stopper 20, and then pull the upper panel 13 to the other side via the handle 19.

According to the above-described transportation trolley of the present invention, articles can be easily loaded by folding the upper panel and opening the upper surface, and articles can be easily loaded by folding the upper panel and closing the upper surface. and theft can be prevented. Further, in the foldable upper panel, every other roller is guided by the rail, so that the folding and unfolding operations can be performed smoothly and reliably.
