Abstract

PURPOSE:To facilitate the inspection of bathtub drain pipes by providing an inspection opening on the bottom wall of a bathtub, removably fitting a cover to the inspection opening water tight, and releasing the cover from the inspection opening. CONSTITUTION:An inspection opening 14 is provided close to the center of a bottom wall 11, the said opening 14 being detachably attached to a cover 2 having a flange 21 peripherally extending along its edge. A leg 31 of sectionally T shaped synthetic rubber, ring type packing 3 is inserted into a gap between the inspection opening 14 and the flange 21 with the inspection opening closed water tight. If sturdy enough to support the weight to be applied at the time of taking a bath, the material of the cover can be the artificial marble of same quality as the bathtub, FRP or the like so that the bather does not feel uncomfortable even when the bather's buttocks come in touch with the cover. The surface of the cover may have a slip proof textured finish. The material of the packing may include elastic synthetic rubber, soft synthetic resin, elastomer, and closed cell synthetic resin or foamed synthetic rubber.

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to bathtubs.

[0002]

2. Description of the Related Art A bath unit in which a bathtub is suspended in a bathtub built-in portion which is connected to a washing place is, for example, the actual Kaihei 3-87483.
As shown in Japanese Patent Publication, it is also known, and it is also possible to provide an inspection port on the waist wall at the boundary between the washroom and the bathtub for hot water supply to the faucet device, connection work of the water supply pipe, and inspection. For example, it is known as shown in Japanese Utility Model Laid-Open No. 4-110589.

[0003]

However, in such a bath unit, in order to inspect the drainage pipe of the bathtub, if it is installed on the first floor, it is necessary to work under a narrow floor. If it is installed on the second floor or higher, or if there is no room for people to dive under the floor, the bathtub must be lifted to work, and in any case the work is extremely difficult. was there.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned conventional problems and provide a bathtub in which the drainage pipe of the bathtub can be easily inspected.

[0005]

The bathtub of the present invention is characterized in that an inspection port is provided on the bottom wall, and a lid body is detachably attached to the inspection port in a watertight manner.

The material of the bath of the present invention is not particularly limited, and examples thereof include artificial marble and glass fiber reinforced thermosetting resin (FR).
P) is preferably used.

The material of the lid of the bathtub of the present invention is not particularly limited as long as it can support the weight at the time of bathing. Artificial marble, FRP, etc. may be mentioned, and the surface may be provided with an anti-slip texture pattern or the like.

The means for maintaining the water tightness between the bath and the lid is
There is no particular limitation, and for example, after the lid is closed, even if the ring-shaped packing is inserted into the gap between the inspection opening of the bathtub and the lid, the ring-shaped packing may be attached to the upper surface of the peripheral edge of the inspection opening or the rear edge of the lid. It may be fixed in advance or any of them may be fixed.

The material of the packing is not particularly limited, and examples thereof include synthetic rubber having a high elasticity, soft synthetic resin, elastomer, closed-cell synthetic resin or synthetic rubber foam.

The shape of the packing is not particularly limited, and may be a hollow body, a solid body or any body. For example, in the case of being inserted into the gap between the inspection opening of the bathtub and the lid, the cross section is formed into a substantially T shape, and the gap is covered by the band-shaped portion at the upper end, and the gap between the inspection opening of the bath and the lid is formed. It is preferable that horizontal protrusions such as a saw blade shape or a fin shape are arranged in parallel on the upper and lower sides of the leg portion to be inserted, so that the close contact with the inspection port and the lid can be increased.

[0011]

In the present invention, the inspection opening is provided on the bottom wall, and the lid is watertightly attached to and detached from the inspection opening. Therefore, even if the bath is not moved by opening the lid, Inspection work can be easily performed from the bathroom.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of an embodiment of the bath according to the present invention.

In FIG. 1, reference numeral 1 denotes a side wall 12 around the entire circumference of the bottom wall 11.
Is an artificial marble bathtub standing upright, and the bottom wall 11 is inclined from the backrest side to the drain port side. A brim 13 is provided at the tip of the side wall 12.

An inspection port 14 is provided substantially in the center of the bottom wall 11, and a lid 2 having a brim 21 extending all around the inspection port 14 is detachably fitted to the inspection port 14. There is. The leg portion 31 of the synthetic rubber annular packing 3 having a substantially T-shaped cross section is inserted into the gap between the inspection port 14 and the brim 21 of the lid 2, and the inspection port 14 is watertightly closed.

Although the embodiment has been described above, the specific structure is not limited to this embodiment, and even if there are design changes and the like within the scope not departing from the gist of the invention, they are included in the invention. . For example, in the embodiment, the leg portion of the packing is formed as a solid body, but it may be formed as a hollow body so as to be flatly deformed by water pressure or the like to increase water tightness. In order to increase the adhesion to the inspection port and the lid, ridges such as saw blades or fins along the longitudinal direction may be juxtaposed on both sides of the packing leg and the back of the strip. Good.

Further, in the embodiment, the inspection opening of the bathtub is closed by dropping the lid into the stepped portion of the inspection opening. However, a protrusion having a substantially L-shaped cross section is provided at one end of the lid. It is also possible to project and to close the projection by inserting the projection into a notch provided in the edge of the inspection port and rotating the lid.

[0017]

Since the present invention is constructed as described above, the drainage pipe of the bathtub can be easily inspected from the inspection port provided on the bottom wall of the bathtub regardless of the installation location of the bathtub. You can
