Description

[Detailed explanation of the idea] The present invention relates to a foldable chair trolley.

Conventional folding chair carts have different functional structures depending on the role of the folding chair cart depending on whether it is for vertical loading, horizontal loading, or child loading.

However, owning multiple folding chair trolleys is a waste of money, and it also requires a large amount of storage space for empty folding chair trolleys that are in use. There was a desire to improve the folding chair trolley to make it smaller.

This invention solves the above-mentioned difficulties, and can be used for vertical stacking, horizontal stacking,
It is an object of the present invention to provide a folding chair carriage which has the role of three folding chair carriages for children and which can be folded and stored under a stage etc. when not in use.

The configuration of the present invention will be explained in detail below according to the illustrated embodiments.

FIG. 1 is a perspective view from above the vertical frame υ showing one embodiment of the present invention in use. Chair non-slip part 5, casters 6
It is made up of.

This folding chair trolley is equipped with casters 6 on the four corners of the back of the bottom 1 of the trolley, and vertical frames 2 and 2 are mounted on the surface of the bottom 1 of the trolley and on each side.
', the horizontal frames 3, 3' are pivoted so that they can be folded inwardly of the bogie, and a support 7 for the central partition 4 is installed in the lateral direction of the center of the bogie bottom 1.
is pivotally connected to the bottom part 1 of the trolley at three places on both sides and in the middle, the support column 7 for the center partition part 4 is connected by the connecting rod 8 for the center partition part 4, and the chair non-slip part 5 is provided on the bottom part 1 of the trolley. has been done.

In the figure, 9 is a stopper that prevents the vertical frame 2 from falling outward from the vertical state, 10 is a knock pin for fixing the vertical frame and the horizontal frame, and 11 is a support 7 for the central partition. This is a dowel pin for fixing.

Although it is possible to integrally form the bottom part 1 of the trolley in a planar shape, it is preferable to construct it by constructing a metal frame and placing a flat plate on the framework.

Hereinafter, the usage conditions of the present invention will be explained, and at the same time, its effects will be explained.

Figure 5 shows how to use the present invention.In particular, in the case of vertical products as shown in Figure 1, it is used as shown in Figure 5A.

In the case of horizontal stacking and seedlings, the knock pin 11 of the central partition 4
, the connecting rod is removed, and the support column 7 is folded and stored in the gap between the central plates, and the folding chair is stacked horizontally and folded as shown in Figure 5, opening and r\.

In this way, the structure of the central partition allows for three different stacking methods, making it versatile.

Furthermore, since the chair non-slip 5 is provided upright, the chair stacking and button removal work is not made difficult and the work efficiency can be extremely improved.

Further, since stoppers 9 are provided upright at the four corners of the lower end of the vertical frame 2, which is subjected to the most load, the load durability is also excellent.

Furthermore, even if the machine is heavy, it can be easily moved because it has casters.

Next, when the present invention is not used and stored, it can be folded.

After folding the central partition as described above, the knock pins are removed as shown in FIG. 4, the horizontal frame 3 is folded inward, and then the vertical frame 2 is folded inward.

By folding it in this way, the trolley becomes extremely flat and can be stored in a space under the stage.

As mentioned above, the present invention aims to provide a folding chair trolley that is versatile, extremely convenient and practical.
