Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a base body for a unit bath in which a washing area and a bathtub are integrally arranged side by side using a molded material such as FRP.

The base of this type of unit bath is a half-unit type in which the washing area and the bathtub are integrally formed and a waist-height side wall is formed around the washing area and the bathtub, and a washing area that is integrated with the side wall. A bathtub fitting type is known, in which a washing tub fitting part is provided in the extension part of the bathtub, and a separately molded bathtub is fitted and installed in the washing tub fitting part.

However, the half-unit type
The side wall (apron) of the bathtub facing the washing area is also integrally molded, so there are many difficulties in integrally molding this side wall part, which tends to cause uneven coloring and mold release defects, and the fitting type of the bathtub. If the main body including the washing area and the bathtub are molded separately, and FRP molding is used, dimensional accuracy is not achieved, making it difficult to fit and fix when mating, making it difficult to maintain watertightness and durability. There are disadvantages that are inferior to.

Therefore, the present invention provides a base for a unit bath in which the side wall facing the washing area can be easily formed, and the bathtub and washing area have an integrated structure that is most excellent in terms of watertightness and durability. However, it is an object of the present invention to correct the drawbacks of the conventional structure.

In order to achieve this objective, the present invention is based on the idea that the washing area and the bathtub have an integral structure. The main point is to attach it in a shape.

Next, the present invention will be explained in detail with reference to an illustrated embodiment.

The base body 1 of the unit bath in the illustrated embodiment is
It is based on a half-unit type molded from FRP, and a waist-height base side wall 4 is formed around the washing area 2 and bathtub 3 by integral molding.

The bathtub 3 has a bathtub main body that is integral with the washing area, and includes a recess 31 formed in an extension of the washing area 2 and side walls 32 surrounding this from three sides. Separate side wall (apron) 3
3 are provided to form a bathtub.

Therefore, the bathtub 3 is formed by forming the recess 31 and the three side walls 3 at the same time as the washing area 2 and the base side walls 4.
2 is integrally molded, and at the time of this integral molding, washing area 2
The side wall facing the side is not molded and left open,
Thereafter, a separately molded side wall structure is attached to the boundary between the washing area 2 and the bathtub 3 (in an open state) in a watertight manner to complete the side wall 33.

In the illustrated embodiment, side walls 32 surrounding the recess 31 of the bathtub 3 are provided on three sides, and separate side walls 33
is erected watertightly fixed to the opposing side walls 32 and the bottom surface of the boundary portion (an extension of the washing area), acts as an apron of the bathtub 3, and constitutes a part of the bathtub 3. The means for fixing the side wall 33 is to arrange embedded wood 34 at the joint part of the side wall 33, and to install reinforcing wood 34 at corresponding locations on the outer surface of the mating washing area 2 and the outer surface of the side wall 32.
5 and fix it with fastening fittings 36 such as wood screws, and make the joint surface watertight with sealant, sealant, etc., or glue and fix the joint surface with water-resistant and heat-resistant adhesive. A combination of both may be used, as long as the side wall 33 is tightly and watertightly joined to the other side and is fixed against the water pressure inside the bathtub. Note that the inside of the side wall 33 is filled with a foamed plastic layer to improve heat retention.

In the illustrated embodiment, the recess 31 of the bathtub 3 is surrounded on three sides by side walls 32, but this is because the bathtub 3 has a rectangular shape in plan.If the bathtub is fan-shaped, the recess 31 is surrounded by side walls 32. It is sufficient to form it into a circular arc shape, surround it with side walls on two sides, and attach an arc-shaped side wall (separate piece) to the remaining open side in post-processing.

The separate side wall 33 is made of the same or different material as the washing area, the bathtub (recess, side wall), and the main body side wall, and can be colored in the same color or in a different color as desired. In the forward position (FIG. 2), the extension 21 of the washing area 2 inserted into the bathtub by the side wall 33 becomes a step inside the bathtub, making it easier to take a bath. In addition, the side wall 33
The height of the side wall 32 is normally a size corresponding to the height of the other side wall 32 (integrally molded), but it can be changed arbitrarily within a range that does not cause any practical problems.

As described above, according to the present invention, since the side wall facing the washing area has a separate structure, there is no problem with molding as this side wall is integrally molded, and moreover, the washing area and the bathtub body are integrally molded. Because of this, watertightness,
It has excellent durability. In addition, since the side walls can be made of different types of molded materials, they can be used with special composite materials, and side walls such as tiles can be easily installed, changing the interior design and making it more creative. becomes possible. Furthermore, in the same model, the shape of the side wall (apron) can be changed freely, which provides excellent functions and effects that cannot be expected from conventional unit baths.
