[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spot type air conditioner assembly wagon which can be easily assembled and disassembled by omitting bolt nut tightening work.

[0002]

2. Description of the Related Art In order to alleviate a severe working environment in the summer at an open work site in a factory or an outdoor work site, a spot type air conditioner adapted to locally eject cold air is adopted. Large spot type air conditioners are equipped with casters directly underneath to allow movement, but in the case of relatively small spot type air conditioners, they are installed on the wagon, and the air outlet is set to an appropriate height and attached to the wagon. It is made portable by casters. Figure 4 shows the assembly type wagon that has been generally adopted in the past.

[0003]

As shown in FIG. 4, in the conventional assembly type wagon, a pipe material is formed into a square U-shaped leg piece, and then the two leg pieces are opposed to each other, and between the leg pieces. The main body frame is provided, and the legs and the main body frame are fastened to each other with a large number of bolts and nuts to assemble. Therefore, assembling the wagon is complicated and requires a long working time.

An object of the present invention is to eliminate the bolt and nut fastening work and to assemble and disassemble the wagon quickly and easily.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above-mentioned object. Two leg pieces formed by bending a U-shape into a square shape using a steel pipe are provided at their central portions. Stacked on top of each other, the center part of the pair of legs is swingably integrated with a connecting shaft, and a stud pin is provided on the lower side surface of each leg, and both legs are bent to form a stud pin for each leg. The main point is that the shelf plate is locked by using, and casters are attached to the lower ends of the leg pieces as needed.

[0006]

Operation: Two leg pieces formed by bending a U-shape into a square shape using a steel pipe are overlapped at their central portions, and the central portions of the pair of leg pieces are swingably integrated with a connecting shaft. Since it is omitted, both leg pieces are opened in an X shape around the connecting shaft, and a shelf plate is placed on the stud pins, whereby quick and easy assembly is possible. It can also be easily disassembled and stored in a low volume.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An assembly type wagon for spot type air conditioner of the present invention will be described below with reference to the illustrated embodiments. 1 in the figure
Is a leg piece, which is formed by bending a square U-shape (U-shape) using a pipe material having a required strength. This pipe material may be either a square pipe or a round pipe.

At the center of the leg 1, that is, at the center of the horizontal portion, a flat shape is provided as shown in FIG. 2, or a vertical hole is formed at this position to form two legs 1, 1.
Are arranged so that their central portions overlap each other, and both leg pieces 1,
The holes 1 are aligned with each other, and the connecting shaft 2 is penetrated into the holes to integrate the two leg pieces 1, 1.

The connecting shaft 2 is formed by crimping one end of a tack as a crimping pin or using a bolt and a nut. The connecting shaft 2 forms a pair of leg pieces 1 and 1, but the connecting shaft 2 is It makes it possible to open the X-shaped legs that intersect each other as an axis.

If necessary, casters 3 are attached to both lower ends of the leg pieces 1 and 1, so that the assembled wagon can be moved, and stud pins 4 are equidistantly arranged on the vertical lower side surfaces of the leg pieces. The stud pin 4 is projected and the shelf plate 5 is locked to the stud pin 4.

The shelf board 5 has such a size that when the leg pieces 1, 1 are opened in an X-shape with the connecting shaft 2 as the center, they can be accommodated in the space surrounded by the vertical portions of the leg pieces 1, 1. Engagement pieces 51 that engage with the stud pins of the leg pieces are provided near the four corners, respectively.

As described above, the wagon is assembled by opening the leg pieces 1 and 1 in the X shape so that the shelf plate is locked to the stud pin. Then, the spot type air conditioner 6 is placed on this, so that the bottom surface of the spot type air conditioner is in contact with the horizontal portion of the leg piece, the bolt 7 is inserted from the mounting hole drilled in the horizontal portion of the leg piece, and screwed to the bottom plate of the air conditioner. Together, the spot type air conditioner 6 and the wagon are integrated.

A drain tank 8 is placed on the shelf plate 5, and condensed water from the spot type air conditioner is guided by a drain pipe to store the water.

[0014]

EFFECT OF THE INVENTION The spot-type air conditioner assembly wagon of the present invention has a pair of leg pieces which are formed by bending a U-shape into a square shape using a steel pipe, with their central portions being overlapped with each other. Since the central part is swingably integrated with the connecting shaft, the wagon can be assembled without using bolts and nuts, and can be quickly assembled and disassembled.
