Description

[Detailed description of the invention] "Purpose of the invention" (Field of industrial application) The present invention relates to waterproof pans for bathrooms.

(Conventional waterproof pan) Two types of waterproof pan A shown in Figures 3 and 4,
B is a structure in which a washing area floor 1 and a installation floor 2 for a bathtub (not shown) are formed adjacent to each other, and in both cases, the installation floor 2 is provided at a lower level than the washing area floor 1. ing. Therefore, when taking a bath, the user can easily step between the washing area floor 1 and the bathtub (not shown).

In the waterproof pan A shown in FIG. 3, an inspection opening 4 was formed approximately in the center of the installation floor surface 2. A lid 6 was attached to the inspection port 4 using screws 8. On the other hand, in the waterproof pan B shown in FIG. 4, an inspection port 5 was formed on the side of the standing floor 2 of the upright wall 3 provided between the washing area floor 1 and the standing floor 2. A lid 7 was attached to the inspection port 5 using screws 8.

(Problems to be Solved by the Invention) In the waterproof pan A shown in Fig. 3, only the portion immediately below it can be seen through the inspection opening 4. Also, regarding the waterproof pan B in Figure 4, its inspection port 5
Only a small portion of the lower part of the washing area floor 1 could be seen from above. Moreover, the opening area of both the inspection ports 4 and 5 is narrow, and it is almost impossible to perform operations other than inspection, such as various operations associated with the installation of waterproof pans A and B, and maintenance of the piping section after installation. Nakatsuta.

The present invention was developed in view of the above circumstances, and provides a new waterproof pan for bathrooms that has a wide inspection range and has an opening that allows various operations other than inspection to be performed. The purpose is to

``Structure of the invention'' (Means for solving problems) The gist of the waterproof pan of the present invention is that the washing area floor and the bathtub installation floor provided at a lower level than the washing area floor are connected to an upright wall. In the waterproof pan for a bathroom, which are formed adjacent to each other through a corner of the stationary floor surface and the upright wall, a working opening communicating with the lower part of the stationary floor surface and the back side of the upright wall is formed as an opening, The work opening is adapted to be fitted with a waterproof lid which is made up of a cover plate for a stationary floor surface and a cover plate for an upright wall connected to each other.

(Function) The work opening is formed at the corner of the standing floor surface and the standing wall, and covers approximately the entire area from the lower part of the standing floor surface to the back of the standing wall, that is, the lower part of the washing area floor surface. You can see it all. Therefore, unlike conventional inspection ports, it is possible to perform various tasks such as adjusting the height of the legs when installing a waterproof pan, constructing piping, and maintaining the piping section.

(Examples) The present invention will be described below based on drawings showing examples thereof.

FIG. 1 is a perspective view showing the waterproof pan of the present invention.
In the waterproof pan of the present invention, a working opening 9 is formed at the corner of the installation floor 2 and the upright wall 3. The work opening 9 has a portion that opens from approximately the center of the installation floor surface 2 to the rising edge of the standing wall 3, and a portion that opens from the rising edge of the standing wall 3 to approximately the entire height of the standing wall 3. The two openings are continuous with each other. In the work opening 9, a peripheral rib 9a having an inverted L-shaped cross section is integrally formed in the portion opening into the installation floor 2 as described above so as to protrude upward from the installation floor 2. It prevents water from entering.

A waterproof lid 10 having an L-shaped cross section and laid down sideways is attached to the work opening 9. The waterproof lid 10 is placed on the installation floor 2 with respect to the work opening 9.
A cover plate 10a that closes the opening of the standing wall 3 and a cover plate 10b that closes the opening of the standing wall 3 are connected. The waterproof lid 10 is fixed by screwing screw holes 11, 11, . In order to improve the water-stopping properties of the waterproof lid 10, it is preferable to provide a packing, a sealing material, or the like made of an appropriate material on its mounting surface.

FIG. 2 is a side sectional view showing a situation in which the waterproof pan of the present invention is installed. As shown in the figure, from the work opening 9 of the waterproof pan of the present invention, both substantially the entire lower part of the installation floor 2 and substantially the entire lower part of the washing area floor 1 can be seen. In addition, from the work opening 9, there is a drain pipe 1 connected to the lower part of the washing area floor 1, etc.
2 installation and maintenance thereof is possible within easy reach. That is, in the waterproof pan of the present invention, the work of connecting the drain pipe 12 and the like can be performed after the waterproof pan is installed. For this reason, conventional waterproof pans (3rd
4), there is no risk of damaging the drain pipe 12 etc. during the installation work. Furthermore,
From the work opening 9, the legs 13 for adjusting the installation height and horizontal level of the waterproof pan can be reached, and the installation height and horizontal level can be adjusted while the waterproof pan is left in place. ing.

(Study of Alternative Embodiments) The opening area of the work opening 9 and its positioning are not limited to those in the above embodiment. Also, work opening 9
A peripheral rib 9a is provided at the opening of the installation floor surface 2 at
Forming is not limited. Furthermore, if the cover plate 10a for the floor surface 2 and the cover plate 10b for the upright wall 3 are configured to swing relative to each other via a hinge or the like, the waterproof cover 10 will take up less space when removed. It's convenient because it doesn't have to be. In this way, the configuration and shape of the waterproof pan of the present invention can be changed as appropriate depending on the embodiment.

"Effect of the invention" As is clear from the above explanation, the waterproof pan for bathrooms according to the invention provides a view of almost the entire lower part of the floor surface on which it is placed and almost the entire lower part of the washing area floor surface. Yes, the inspection range is extremely wide. Moreover, from the work opening, it is possible to install and maintain a drain pipe, etc., and the height of the legs can be adjusted. Therefore, it has many excellent advantages, such as making the installation work of the waterproof pan easier and preventing damage to drain pipes, etc.
