Description

[Detailed Description of the Invention] The present invention is a bathtub, particularly for use in general households, and has improved legs.

Traditionally, bathtubs have been used in ordinary households.
In order to facilitate drainage, legs were provided at the four corners of the bottom, and a gap was formed between the bottom of the bathtub and the floor on which the bathtub was installed.

Since such conventional bathtubs had legs only at the four corners of the bottom, the weight of the hot water in the bathtub and the weight of the bather were all supported by these four legs. The weight of these baths and the weight of the bathers varies depending on the size of the bathtub and the number of bathers, but it weighs at least 200 kg, so conventional bathtubs have had to have their bottoms strengthened. It was necessary to do so.

In order to improve the strength of the bottom as described above, conventional bathtubs are equipped with measures such as increasing the thickness of the bottom of the bathtub, providing ribs on the back side of the bottom of the bathtub, and providing unevenness on the bottom of the bathtub. It had become unavoidable.

Therefore, in this invention, in addition to providing legs similar to conventional ones at the four corners of the bottom of the bathtub, we also provide a separate center leg in the center of the bottom of the bathtub, so that the bottom of the bathtub can withstand use without significantly improving the strength of the bottom itself. Its purpose is to provide a bathtub that provides a comfortable bathtub.

In order to achieve the above object, the present invention is characterized in that legs are provided at each of the four corners of the bottom, and a central leg is also provided protruding from the center of the bottom.

An embodiment of the present invention will be described below with reference to an illustrated example.

FIG. 1 shows the bottom 14 of the bathtub 10, which has legs 11 at each of its four corners, and a central leg 12 at the center. Additionally, located slightly to the right in the drawing is a drain port 13 for discarding hot water in the bathtub 10.

Further, FIG. 2 is a sectional view of the central leg 12 portion.
Here, the bottom 14 of the bathtub 10 is formed by a bottom surface 15 of the bathtub 10 itself and a heat insulating material 16 provided on the back side of the bottom surface 15 of the bathtub 10.
The central leg 12 also includes a support plate 17 directly fixed to the back side of the bottom surface 15 of the bathtub 10, and a cylindrical protrusion 18 provided to protrude downward from the support plate 17.
It is formed by. Note that this support plate 17
The protrusions 18 are also covered with the heat insulating material 16 except for the tips of the protrusions 18 from the viewpoint of heat insulation effect.

In the present invention, the weight of the hot water in the bathtub 10 and the weight of the bather are supported by the four legs 11 and the center leg 12. Therefore, even if the bottom part 14 were to sag, for example, since the central leg 12 is provided, the sag will occur between this central leg 12 and the legs 11 provided at the four corners of the bottom part 14. However, the deflection here is approximately 1/4 to 1/8 because the distance between the supporting parts is approximately half.
It will be about. This also means that the conventional bathtub 10
In the bathtub 10 according to the present invention, the bottom 14 of the bathtub 10 can be formed with approximately 1/4 to 1/8 strength compared to the bottom 14 of the bathtub 10.

Therefore, the bathtub 10 according to the present invention can significantly reduce the material used for the bottom 14 compared to the conventional bathtub 10. Also, for example, when a bather is in the bathtub 1
Even if the bathtub 10 is violently thrown, most of the impact force will be transmitted to the center leg 12 because the center leg 12 is provided at the center of the bathtub 10, and the bathtub 10 will not be damaged. .

Note that this center leg 12 is connected to the center bottom 1 of the bathtub 10.
4. If it is formed approximately at the center and protrudes by the same height as the legs 11, the shape will not be changed. If the protrusion 18 is formed to be fixed on the bottom surface 1, the weight supported by the center leg 12 is reduced to the bottom surface 1.
Since the support can be widely distributed with 5, there will be no damage to the bottom surface 15 of the central leg 12 portion. Furthermore, convexity 1
The shape of 8 is not limited to the cylindrical shape as in the example,
It may be columnar.

As explained above, the present invention not only saves the material of the bottom of the bathtub, but also prevents the bottom from being damaged even when some external impact is applied.
