Description

[Detailed description of the invention] The present invention is an improvement of a wheel support structure provided to facilitate the movement of a main body formed by a front case and a rear case made of synthetic resin, such as a small air conditioner. One of the purposes is to suppress as much as possible the intrusion of dirt and the like through the gap between the main body and the wheels.

Conventionally, this type of wheel support structure has been constructed by pouring synthetic resin into molds a, l), c, and d, forming a front case e and a rear case f individually, as shown in Fig. 3. When pressed together, they constituted the main body g.

At this time, at the same time, the wheel holder was formed integrally with the part i, and the wheel holder was parted and passed through the part i through the wheel j and the axle k, and was prevented from being removed by a screw l.

However, the front case e and the rear case f are molds a, l)
, c, d, so the molds a, l),
Since a slope α is formed when removing the wheels c and d, when installing the wheel j, a gap is sometimes formed between the wheel j and the wheel j due to the slope α. It had drawbacks such as interfering with rotation.

Hereinafter, FIG. 1 of the attached drawings showing one embodiment of the present invention,
This will be explained with reference to FIG.

In the figure, reference numeral 1 denotes the main body of the air conditioner, which is constructed by abutting a front case 2 and a rear case 3 made of synthetic resin, and houses a well-known refrigeration cycle (not shown) and the like inside.

The front case 2 and the rear case 3 are formed into a mold 4 as shown in FIG.
, 5, 6.7, respectively, and the side surfaces of the molds 4, 5, 6.7 have a draft angle β1. β2 is formed.

Reference numerals 8 and 9 are wheel support parts integrally formed in the front case 2 and rear case 3, respectively, and the draft angles β1. β2
There are protrusions g a and 9 a in which no is formed.

Reference numeral 10 denotes a wheel rotatably attached to the wheel support section 8, which is made of synthetic resin and has an axle 11 and a metal fitting 1.
2 and screw 13 prevent removal.

Therefore, since the end surfaces of the wheel 9 and the wheel support part 8 are parallel, the gap T between them is small, and dirt and the like are less likely to enter through this gap T, allowing the wheel 11 to rotate smoothly and preventing the inside of the main body 1 from entering. Intrusion of garbage, etc. can also be suppressed as much as possible.

Further, since the wheel support portion 8 is formed integrally with the front case 2 and the rear case 3 when they are formed individually, it is easy to manufacture and suitable for mass production.

As is clear from the above embodiments, the wheel support structure of the present invention has a main body composed of a front case and a rear case made of synthetic resin, a wheel support part is provided on the abutting surface of the main body, and the wheel support structure A protruding part that protrudes parallel to the end face of the wheel is integrally provided on the wheel, making it possible to reduce the gap between the wheel and the wheel support part, minimizing the intrusion of dirt, etc. through this gap, and furthermore, the front Since the protrusion can be integrally formed at the same time as the case and the rear case are individually formed, it has various advantages, such as being easy to manufacture and suitable for mass production.
