Description

[Detailed description of the invention] [Industrial application field] The present invention is a stackable chair transport system in which multiple trolleys each capable of transporting chairs can be stacked and stored in the front and rear directions so as not to take up space. Regarding trolleys.

[Conventional technology]

As shown in Figure 6, this type of conventional transport trolley has four underframes on which chairs can be stacked.
It had a structure with casters at each lower corner.

[Problem that the invention attempts to solve]

Therefore, since there are no handles, it is unsafe to move or stack chairs, and it is unstable to lift and stack them one after another when storing multiple trolleys. , and 1
There were problems in that it was impossible for humans to handle and it was inconvenient to handle.

[Means for solving problems]

The present invention solves this problem and makes it possible to store the chair by stacking it well in the front and back direction.For this purpose, a flat rectangular underframe on which the lower ends of the legs of the chair can be placed is placed at a height in the front. Both casters are installed vertically on both sides of the rear part of the underframe in an inclined manner, and both casters are installed vertically on both sides of the front part with a width wider than between the two casters. , a frame on which a chair can be fitted inward to lean against, and has a handle at the upper end, extends upwardly on the rear side.

[Effect]

Therefore, it is possible to fit the stacked chairs into the frame and lean them against each other to prevent the load from falling apart, and to move the chairs by holding the handles. When storing the carts, the front portions of the rear carts are pushed in from the rear of the front cart, and the carts can be stacked one after another for storage.

〔Example〕

Next, the embodiment shown in the drawings will be described. Figure 1 shows an exploded perspective view of the entire trolley. Two of the four legs of chair A are attached to each side of the underframe 1, which is rectangular in plan and formed by bending the frame. Support frames 1a, 1a that can receive and support
are arranged in series, and both casters 2, 2 are arranged vertically from both rear sides of the underframe 1.

Reference numeral 5 indicates the entire frame, and the lower parts of both upper frames 5 b , 5 b each having a dogleg shape on the side are connected at their upper ends by a horizontal handle 4 to the upper parts of both lower frames 5 ^a , 5 ^a having a dogleg shape on the side. The lower upstanding parts of the lower frames 5a, 5a are respectively fixed to the outer sides of the front part of the underframe 1, and Below the lower frames 5a, 5a, both casters 3, 3, which are wider than the space between the two casters 2, 2, are installed vertically, but depending on the mounting height of each caster, they are installed diagonally so that the underframe 1 is at the front height. In addition, on both sides of the underframe 1 near the front, stopper rods 7, 7 are provided, respectively, which stand between the support frame 1a and the upper part of the lower frame 5a, and the stopper rods 7, 7 are provided on both sides near the front of the underframe 1. The frame 5 is arranged so that the chair A can be fitted inside the frame 5 which is inclined and extended in a dogleg shape.
On both sides of the upper side, a horizontally long back support 8 formed by coating the outer periphery of a steel plate with rubber is connected at both ends with bolt nuts 9, respectively.

Therefore, as shown in FIG.
By stacking each chair A on top of the chair A by placing it in line with chairs A and 1a and leaning it against the back rest 8, it becomes possible to load a large number of chairs A without causing the load to fall apart. This means that the cart can be moved by holding the part 4.

In addition, if each truck is not used, as shown in Figures 4 and 5, from the rear of the front truck,
By pushing the front part of the rear truck, it is possible to approach the lower front of the frame 5 of the rear truck so that it overlaps with the stopper rods 7, 7 of the front truck. This means that the cart can be stacked in the front and rear directions and stored in a narrow space.

[Effect of idea]

In this way, the present invention allows a large number of chairs to be stacked and loaded on the trolley in a manner that prevents them from collapsing, and also allows the chairs to be moved and transported safely by grasping the handles 4. When a large number of trolleys are not used, they can be stacked close to each other so that they overlap one another, so they can be stored well in a narrow space, and have the advantage of being of a simple structure and being able to be suitably implemented.

Claims (1)

[Scope of utility model registration request] The underframe 1 is formed into a rectangular planar shape on which the lower ends of the legs of the chair A can be placed.The underframe 1 is tilted with the front height raised, and both casters 2, 2 are provided on both sides of the rear of the underframe 1. In a truck equipped with front legs that are wider than the space between the casters 2, 2 on both rear sides and are adapted to attach the front casters 3, 3, the upper parts of the front legs 5a, 5a are bent rearward and diagonally upward at the rear. It is erected and engaged with stopper rods 7, 7 which stand up from both sides near the front of the underframe 1, and furthermore, the upper frame is positioned at the upper end of the front leg on the back of the back of the chair on which it is placed. This stackable chair transport trolley is formed by fitting and engaging the lower front parts of frames 4 and 5 formed by bending the frames 4 and 5 in a dogleg shape.
