Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a supporting leg structure suitable for fixing, moving, and lifting a floor-standing air conditioner such as a spot type air conditioner.

(Prior art) The legs of a conventional floor-standing air conditioner are shown in Figures 8 to 1.
As shown in Figure 0, set bolt angle material 1
3 attached to the bottom frame 6, the legs 14 in the form of a truncated cone or truncated pyramid are welded and fixed to the lower surface of the bottom frame 6, and the bottom frame 6 is set at an appropriate height H relative to the floor surface.
Common structures include a structure in which legs 15 made of a square bar or a round bar are welded and fixed to the lower surface of the bottom frame 6 and similarly floated by an appropriate height H.

(Problems to be solved by the invention) Among the various conventional leg structures mentioned above, the one shown in Fig. 8 has the advantage of being securely fixed and easy to work with, but it is difficult to move due to repositioning or to be transported by a forklift. However, in the case of the one shown in Figures 9 and 10, there is a problem with the reliability of fixing, and the height of the legs is not appropriate. There was a problem with the forklift's claw not being able to be inserted.

In order to address these problems, the present invention not only ensures secure fixation, but also improves workability during lift transportation, and furthermore, when converting to a mobile type, it can be easily replaced with casters. By providing structural legs, it has been possible to overcome the conventional drawbacks, and the object is to increase adaptability to a variety of usage modes and to contribute to rationalization of transportation.

(Means for Solving the Problems) Therefore, in order to achieve the above-mentioned object, the present invention has holes 8 drilled at a plurality of locations in the bottom frame 6 of the air conditioner, and the holes 8 are connected to the top side of the bottom frame 6 of the air conditioner. A nut 9 having a screw hole with a smaller diameter than that of the forklift is fixed by welding, and the leg part 1 forms a regular hexagonal prism that is longer than the thickness of the forklift claw and has a larger diameter than the hole 8.
1 and a bolt part 12 corresponding to the nut 9 are coaxially integrated.
The structure is such that the two are screwed together.

(Function) Since the leg portion 11 of the leg member 10 forms a regular hexagonal prism, it is possible to securely grip the leg member 10 from any direction when tightening with a spanner or adjustable spanner, and the work can be easily performed. By sandwiching and tightening the bottom frame 6 with the nuts 9 and 9, mechanical strength is increased, and by drilling shallow holes in the floor that can circumscribe the regular hexagon of the legs 11, the position can be fixed securely.

Furthermore, since the legs are long enough to allow the lift claws to be inserted, it is easy to transport the lift, and since it is screwed together, it is easy to replace the casters and can be converted into a mobile type.

(Example) Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

1 to 3 show a floor-standing air conditioner, for example, a spot air conditioner, according to an embodiment of the present invention, in which a cubic casing 1 includes a compressor, a condenser, an evaporator, Each fan, expansion valve, and other equipment for the refrigeration system is housed, and on the side there is an air inlet 22 for the condenser and an air inlet 3 for the evaporator, and on the top there is an exhaust outlet 4 for the condenser, and an air inlet 3 for the evaporator. Cold air outlets 5 are opened, and by connecting a blower duct to each of the air outlets 5, the cold air can be sent to the area where the worker is located.

6 is a bottom frame serving as a strength member supporting each device for the refrigeration system and the outer panel of the casing;
As one example is shown in cross section in the figure, the frame is formed by polymerizing and welding a 2.3 mm thick angle steel material 6A and a 3.2 mm thick steel band plate 6B, and a casing outer plate 7 is fixed to the outer surface of the frame.

This bottom frame 6 is provided with holes 8 having an appropriate diameter of, for example, 17.5 mm, at a plurality of locations, for example, at four locations near the left end and right end of each of the front and rear bottom frames 6, 6. A nut 9 having a threaded hole with a diameter smaller than hole 8, for example 16 mm, is fixed by welding on the side so that both holes are concentric.

Leg members 10 are attached to the four locations where the nuts 9 are fixed.

The leg member 10 is shown in FIGS. 5 and 6, and has a structure in which a leg portion 11 and a bolt portion 12 are coaxially integrated, and the leg portion 11 is longer than the thickness of the forklift's claw. For example, it is a regular hexagonal prism with a length of 100 mm and a larger diameter than the hole 8, and in the illustrated example, the distance between opposing sides of the hexagon is 21 mm.

On the other hand, the bolt part 12 is formed into a bolt of an appropriate length, for example, 17 mm, and has a corresponding male thread that can be screwed into the nut 9. A leg material 10 in the form of a rod with a total length of about 120 mm including the parts is obtained, and this leg material 10 is attached to the bolt part 12.
The four leg members 1 are attached to the lower surface of the bottom frame 6 by screwing them into the nuts 9 respectively.
0 is attached, and in this way, when the spot air conditioner is placed on the floor, the bottom plate of the casing of the spot air conditioner is in a floating state with a distance of 10 mm from the floor surface.

Since the bottom plate of the casing is separated from the floor in this way, the claws of the forklift can be easily inserted between the bottom plate of the casing and the floor when transporting by lift, and when shipped from a factory or warehouse, it can be placed on a pallet, etc. There will be no need.

On the other hand, in the case of on-site installation, if shallow circular holes of a size circumscribing the regular hexagon of the legs 11 are recessed in the floor to correspond to the four legs 10, the spot air conditioner can be installed immovably. It is.

In addition, since the leg portion 11 has a regular hexagonal shape,
Installation work using a spanner is reliable and easy.
Further, since the screw connection is performed, if a caster 16 having a bolt portion 17 of the same size as the mounting shaft as shown in FIG. 7 is prepared, it can be easily replaced and used as a movable type.

(Effects of the invention) In the present invention, the leg members 10 are screwed to the bottom frame 6 in consideration of the claw insertion allowance of a forklift, so that lift transportation is easy.

Furthermore, since the leg portion 11 has a regular hexagonal shape,
Easy to install and remove using a wrench.

In addition, since the nuts 9 are integrally fixed to the bottom frame 6 by welding, the mechanical strength is high, and the leg members 10 can be attached and detached by simply turning them, so the workability is good.
