[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double structure floor of a bathroom.

[0002]

2. Description of the Related Art FIG. 8 is a side sectional view of a conventional bathroom. A bathroom 100 has a floor pan 101 having a washing area 102 and a bathtub installation section 103, and a bathtub installation section 103 provided with a bathtub 104. The floor pan 101 has a configuration in which the height of the bathtub installation portion 103 is lower than that of the washroom 102, and the wall panel placement portion 105 on the washroom 102 side is provided more than the wall panel placement portion 106 facing the bathtub 104. Is formed at a lower position, and a door 109 serving as an entrance / exit to the adjacent chamber 108 is mounted on the wall panel mounting portion 105 via a mounting frame 107. Then, the lower frame (sliding) 110 of the mounting frame 107 and the washing area 1
There is a step between 02. In addition, 111 is a bathtub 104
Rim, 112 is the floor of the building frame, and A is the installation height between the floor 112 of the building frame and the floor pan 101.

FIG. 9 is a side sectional view of another conventional bathroom,
The bathroom 150 is configured such that the washing place 152 of the floor pan 151 and the bathtub installation portion 153 are provided at substantially the same height, and the bathtub 154 is installed in the bathtub installation portion 153. The wall panel mounting portions 155A and 155B of the floor pan 151 have substantially the same height as the rim 156 of the bath tub 54, but the wall panel mounting portion 155B on the side of the washing place 152 is preliminarily provided at the entrance / exit portion with the adjacent room (not shown). A cutout 158 is provided from the to the rising portion 157. A mounting frame 159 is fixed to the notch 158 and a door 160 is provided. Lower frame (sliding) 161 of the mounting frame 159 and the washing area 1
There is a step between 52. In this type, since the height from the floor 162 of the building frame to the floor pan 151 can be set low, it is suitable for an apartment house or the like where the installation height B between the floor 162 of the building frame and the floor pan 151 is not enough. There is.

[0004]

Floor pan 10 of FIG. 8 described above.
In No. 1, it is installed in a single-family house where the installation height A between the floor 112 of the building frame and the floor 113 of the adjacent room 108 can be sufficiently taken, and a drainage pipe is installed under the floor pan 101 with a sufficient drainage gradient. Although it can be done, it is difficult to apply to an apartment house where the installation height A cannot be sufficiently obtained. Also, the washing place 102
To the lower frame (sliding) 110 of the mounting frame 107 of the door 109
The height is around 60 to 100 mm, and there are steps,
When an elderly person with weakened legs or a handicapped person enters or leaves the washing room 102 from the adjoining room 108, there is a risk that he / she may stumble at the step between the washing room 102 and the lower frame (sliding) 110.

Another floor pan 151 shown in FIG. 9 is suitable for an apartment house or the like where the installation height B between the floor 162 of the building frame and the floor pan 151 is not enough. Since the height B is low, the drainage pipe disposed below the floor pan 151 cannot have a sufficient drainage gradient, and the drainage performance is poor.

Further, since the washing place 152 of the floor pan 151 and the bathtub installation portion 153 have substantially the same height, the height from the washing place 152 to the rim 156 of the bathtub 154 becomes high, so that the elderly who have weakened legs and waists. Also, it is difficult to use because people with disabilities cannot lift their legs during bathing. Further, as with the floor pan 101 of FIG. 8, 6 is provided between the lower frame (sliding) 161 of the entrance and exit and the washing place 152.
Since there is a step of about 0 to 100 mm, there is a possibility that an elderly person who has weakened his / her legs or a handicapped person may stumble at the step between the washing room 151 and the lower frame (sliding) 161 when entering or leaving the washing room 151 from the next room. is there.

When the user ages, it is necessary to modify the bathroom 150 so that it is easy to use, but the floor pan 151 has a notch 158 in advance from the wall panel mounting portion 155B on the washing place 152 side to the rising portion 157. Since the location of the entrance and exit and the width of the entrance and exit are determined in advance, the floor pan 151 does not need to be remodeled so that the legs and waist are weakened due to aging and the caregiver can easily receive care. There is the inconvenience of having to make a major modification to replace it.

Further, since a notch 158 is provided in advance from the wall panel mounting portion 155B on the side of the washing place 152 to the rising portion 157 in order to provide a doorway with the adjacent room, both the doorway position and the doorway width dimension are previously set. It will be decided.

Therefore, in order to be able to respond to various sites,
Rise 15 on three sides of the washing area 152 except for the bath 154 side
Since it is necessary to separately prepare the floor pans 151 each provided with the cutouts 158 for the entrances and exits in FIG. 7, there is a manufacturing cost, and one floor pan can cope with any site. Compared with the above, there are inconveniences such as extra space for inventory management and a heavy physical load.

On the orderer's side, even if the floor pan 151 has the same vertical and horizontal dimensions, there are at least three types of floor pans in which the positions of the cutouts 156 for the entrance and exit are different. Therefore, confirmation of the ordered floor pan 151 is possible. There is an inconvenience that work is required, and in addition, it is not possible to promptly respond to a sudden change on site.

Therefore, an object of the present invention is to change the level difference between the entrance and exit of a bathroom or the like and the height from the washing area to the rim of the bathtub according to the site, and to set the entrance and exit positions and frontage freely to maintain a healthy condition. Of course, it is to provide a double structure floor of the bathroom that is easy to use for the elderly, the disabled and the like.

[0012]

In order to achieve the above object, the first aspect of the present invention is to provide a floor pan in which a washing place, a ridge portion, and a bathtub installation portion having substantially the same height as the washing place are connected. In a bathroom where a wall panel placing part is provided in the peripheral part, a wall panel is erected on this wall panel placing part, a door is attached, a bathtub is placed in the bathtub placing part, and a second floor is laid in the washing area. So, between the wall panel rest on the side of the next room facing the washroom and the second floor,
The concave member that constitutes the drainage groove is separately placed, the upper surface of this concave member is covered with grating, and the upper surface of this grating,
The upper surface of the surface material and the floor surface of the adjacent room are provided at substantially the same height.

Therefore, since the so-called raised bottom is used, the height dimension from the washing area to the rim of the bathtub is reduced. Second
By laying the floor, it is possible to make the floor of the dressing room and the floor of the wash room flush. In addition, since the wash water that has flown on the floor that will become a new washing place flows down from the grating to the drain, it does not overflow into the adjacent room.

According to the second aspect of the present invention, since the drain and the drain provided in the washing place are connected by the flexible pipe, the wash water discharged at the washing place is quickly passed from the flexible pipe to the drain through the drain. Can be flushed to.

According to the third aspect of the present invention, the second floor comprises the floor body and the detachable and replaceable surface material fixed on the floor body. Therefore, the second floor is the floor body or the surface material. You can change the height just by replacing.

Similarly, by placing the second floor 19 on the washing floor 6, the step R from the washing floor 6 to the lower frame 16 which usually has a step of about 60 to 100 mm is the thickness s + t of the second floor 19. Because it becomes lower and the step becomes r (R-r = s
+ T), there is little possibility that an elderly person who has weakened his / her legs or a handicapped person will trip over the bathroom 1 from the dressing room 13 by tripping his / her legs at the step r.

If a second floor 19B having a larger thickness is placed as shown by the phantom line, the step between the second floor 19B and the lower frame 16 becomes m, and the second floor 19 is installed. It becomes rm lower than that at the time and becomes a step m (R-m
= S + t), since the step can be almost eliminated, there is less risk that an elderly person who has weakened his / her legs or a handicapped person will get caught in the bathroom 1 from the dressing room 13 and get caught in the step r and stumble. .

Since the thickness (height) of the second floor 19 can be freely set in this manner, the height from the entrance / exit of the bathroom 1 and the washing scene (the second floor 19 surface) of the bathtub 8 can be set. Since it can be changed according to the site, the user can coordinate the bathroom 1 according to his / her own preference and can respond to the diversification of the user's preference, not limited to the above-mentioned effects.

Further, since the height of the second floor 19 can be freely changed, a notch for providing an entrance is provided at the rising portion of the floor pan 2 so that the location of the entrance on the site can be adjusted. Since it is not necessary to provide many kinds of floor pans 2 having different cutout positions, the floor pans 2 can be shared, and therefore the manufacturing cost and the physical distribution cost can be significantly reduced. Since the floor pan 2 can be shared, order mistakes can be prevented, and in turn, indirect costs such as personnel costs and complaint processing costs can be reduced.

Further, since the floor body 24 of the second floor 19 is formed of a member having a heat insulating property, it is particularly suitable for use in cold regions. Further, since the surface material 25 is formed of a member having a shock absorbing property, even if the user falls down, it will not cause much pain and will not cause a serious injury.
