Description

[Detailed Description of the Invention] The present invention relates to a bathtub made of FRP, stainless steel, or the like.

Conventionally, this type of bathtub has a strip-shaped rib extending around the bottom periphery of the bathtub, and legs are formed in at least three locations by fitting cushioning material into desired locations of the strip-shaped rib.
The legs allow the bathtub to be placed on the floor, so that even if the floor is slightly uneven, the bathtub can be stabilized as it is, or by simply correcting the unevenness of the floor. In order to allow the bathtub to be placed on the bathtub, the bathtub is supported only at a few points around the periphery of the bottom surface.

However, in such conventional bathtubs, legs and ribs are provided only on the periphery of the bottom, so while it is possible to install the bathtub stably when it is empty, the strength of the bottom plate is limited. There is a problem in that when a bathtub is filled with hot water to take a bath, the center of the bottom plate of the bathtub is bent by the weight of the hot water and the bather, which causes a sense of anxiety to the bather.

Furthermore, in this case, the entire load applied to the bathtub, that is, the weight of the bathtub, the load of hot water, and the load of the bather, is concentrated only on the legs, so the bathtub was placed on a waterproof pan made of FRP. In some cases, the waterproof pan may be scratched or damaged, and when the bathtub is placed on a hard floor such as a tile floor, there are many accidents where the strip ribs themselves are damaged. It was occurring.

Therefore, it may be possible to provide legs at the center of the bottom of the bathtub, but in this case, there is no problem if the floor on which the bathtub is placed is a smooth surface, but if not, there is a gap between the bathtub and the floor. This creates a problem in that the bathtub cannot be installed stably.

The present invention was developed to solve these conventional problems, and when there is no significant load on the bottom plate, such as when the bathtub is empty, the main legs attached to the bottom periphery are used to lift the bathtub. , and the auxiliary legs support the vicinity of the center of the bottom plate only when a load is applied to the bottom plate and the center bends, such as when a bathtub is filled with hot water. This improves safety and strength during bathing without compromising the stability of the bathtub at all.

This configuration will be explained below based on an illustrated embodiment.
In the figures to FIG. 3, 1 is a bathtub body made of FRP or stainless steel, 2 is a floor plate of the bathtub body, and 2a is a bottom surface of the floor plate 2.As is known, from the bottom surface 2a, A band-shaped rib 3 is extended along the periphery, and a cushioning material 4 made of an elastic material such as rubber is provided at the corner of the band-shaped rib 3.
4... is fitted, and as a result, the main leg portions 5, 5.
・Crystals are formed.

That is, the cushioning materials 4, 4, . As shown in FIG. 5, the main leg parts 5, 5, . . . . may be provided at three or more locations on the bottom surface 2a of the bathtub body 1 so that the bathtub body 1 can be stably supported on the floor surface A. It may be formed by protruding a protrusion from 2a.

Furthermore, in the present invention, in addition to the main legs 5, 5, etc. provided on the outer circumferential side of the bottom surface 2a, one or several locations are provided on the inner circumferential side of the bottom surface 2a, preferably near the substantially central portion. In the illustrated case, reinforcing ribs 7, 7 are provided between the belt-shaped ribs 3.
At the same time, as shown in FIG. 6, cushions 8.8, which are made of an elastic material such as rubber and have a generally concave shape on the longitudinal section, are fitted at desired locations on the ribs 7.7. , thereby forming the auxiliary leg portions 6.6.

The height of the auxiliary legs 6, 6... is set slightly lower than the height of the main legs 5, 5... as shown in Figs. In the installed state, the lower surfaces of the auxiliary legs 6, 6... are the main legs 5, 5...
It is positioned above the plane containing...
Therefore, when the bathtub body 1 is placed on the floor A etc. by the main legs 5, 5..., the auxiliary legs 6, 6...
The tips of .

However, in this lever bathtub, when the bathtub body 1 is empty,
It is supported on the floor surface A by the main legs 5, 5..., but when it is filled with hot water or when taking a bath, a load is applied to the bottom surface 2, and the bottom plate 2 is When the central part bends downward, the auxiliary legs 6, 6...
is pressed onto the floor surface A, and thus the bottom plate 2 is supported by the auxiliary legs 6, 6, . . . so that the bottom plate 2 does not bend any further.

In addition to the band-like ribs 3, in the illustrated embodiment in which auxiliary ribs 7.7 are extended between them, the bottom plate 2 has a high rigidity, and therefore the bottom plate 2 itself can be difficult to bend.

Note that the dimension of the gap δ should be determined by considering the rigidity of the bottom plate 2 and the load applied to it, but for example, if the bathroom body 1 is made of FRP and the thickness of the bottom plate 2 is about 4 m, In such cases, a value of about 2wn is usually adopted.

As explained above, in the present invention, when the bathtub body 1 is empty, the main leg portion 5 provided on the outer peripheral side of the bottom surface 2a
, 5..., and when a large load is applied to the bottom plate 2 and the center part of the bottom plate 2 bends, such as when bathing by filling the bathtub body 1 with hot water. Since the inner circumferential side of the bottom plate 2 is supported only by the auxiliary legs 6.6, the bathtub can be stably installed on the floor A, etc., and also Also, the bottom surface 2 will not be bent greatly, and the bather will not feel uneasy.

Furthermore, when taking a bath, the load applied to the bathtub is not only applied to the main legs 5, 5... but also to the auxiliary legs 6, 6...
..., so there is no chance of damage to the waterproof pan or strip ribs, etc., and the auxiliary legs 6, 6, etc. are dispersed on the floor A etc. due to the deflection of the bottom plate 2. Just by pressing it, it will not bend any further downwards, so there will be no change in the initially set installation condition of the bathtub due to the main legs 5, 5, and so on. It becomes possible to ensure a stable installation state.
