DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underfloor type toilet which is exposed in a living room when used and is stored under the floor of the living room when not in use.

[0002]

2. Description of the Related Art Generally, in a normal house, a toilet is provided in a room formed separately from living rooms such as a living room, a study, and a bedroom, usually in a room furthest from the center of the house. I have. However, in recent years, housing with a very small building area (living area) may be constructed due to a rise in land prices, etc. In such a very narrow house, for example, a relatively inexpensive house for sale in an urban area, etc. In some cases, it may be difficult to secure one room for the toilet. Thus, in a house having such a very small building area, a bathroom may be provided with a toilet.

[0003]

However, if a toilet is provided in the bathroom in this manner, the use of the toilet or the bathroom is restricted when a plurality of people are living or occupying the house. There is a problem that there are many. In addition, it is virtually impossible to add a common toilet in a living room, for example, a living room.

[0004] In recent years, the average life expectancy has been greatly extended and the number of elderly people is increasing. However, for elderly people who have difficulty walking, it takes considerable effort to go to the toilet at the end of the house where they live. There is a problem. In addition, even if it is not an elderly person, it may be difficult for a physically handicapped person or a person who is undergoing treatment due to a leg injury to go to the toilet.
In such a case, a portable toilet may be used, but many people feel resistance to using the portable toilet in the living room.

[0005] The present invention has been made to solve the above-mentioned conventional problems, and provides a toilet capable of making a substantial living space as large as possible in a house having a very small building area. Is an issue to be solved.

[0006]

Means for Solving the Problems To solve the above-mentioned problems, the underfloor-storable toilet according to the present invention is characterized in that: (a) below the floor notch formed by cutting out a part of the floor of a living room; A housing disposed on the ground; (b) a lid member hinged to an upper end portion or a floor portion of a side wall of the housing and capable of opening and closing a floor cutout; and (c) disposed on a bottom wall of the housing. A lifting device whose loading surface can be raised and lowered between a position slightly above the ground in the vertical direction and a position on the upper surface of the floor, and (d) a loading platform of the lifting device A movable table disposed on the surface; and (e) disposed on the movable table, the upper end of which is positioned lower than the upper end of the housing when the platform surface of the lifting / lowering device is at the lowest position. Flush with a flush toilet whose height is set to (F) When the movable platform is raised by the lifting device, the circular arc formed at the upper end corner of the vertical wall of the movable platform is brought into sliding contact with the back surface of the lid member to push the lid member open naturally. A lid member opening / closing means for closing the lid member naturally while sliding the rounded portion with the back surface of the lid member as the movable table is lowered, and (g) movable when the toilet is used. While the table is arranged at the uppermost position and the toilet is exposed in the living room, when the toilet is not used, the movable table is arranged at the lowermost position and the toilet is stored under the floor, and the floor cutout is closed by the lid member. It is characterized by the following.

[0007] In this toilet under the floor, first,
When the toilet is not used, the toilet bowl and the like can be stored under the floor, and the entire living room can be used as a living space. Therefore, even when the building area of the house is very small, a relatively large living space can be secured.

[0008] That is, if the lifting device is raised and the movable table and the toilet are arranged at the uppermost position, the toilet is exposed in the living room, and those who are present in the living room can use the toilet to use the toilet. Therefore, even if the person in the room is an elderly person or a physically handicapped person who has difficulty walking, it can be easily used. Also, after the use is completed, the lifting device is lowered, the movable table and the toilet are arranged at the lowest position, stored under the floor, and the floor notch is closed with the lid member. It becomes an ordinary living room with the lid member) also as a living space.
Therefore, the area of the living room can be increased. In other words, even in a house having a small building area, a toilet suitable for an aging society can be obtained, in which the area of a living room can be made as large as possible, and a person who has difficulty walking can easily use the room.

Further, in this toilet under the floor, the lid opening / closing means slides the rounded portion against the back surface of the lid when the movable base is raised, and pushes the lid naturally open, while the lid is opened and closed when the movable base is lowered. The lid member is naturally closed while sliding on the back surface of the lid member, so that the lid member is opened and closed naturally,
There is no need to provide a special mechanical device for opening and closing the lid member. For this reason, the structure of the underfloor-restroom-type toilet is simplified, and its manufacturing cost is reduced.

[0010] In the underfloor toilet, it is preferable that a toilet device and a curtain device for hiding (shielding) a user of the toilet when the toilet is used are provided. The curtain device may be of a manual type, but is preferably of an automatic opening and closing type. In this way, a person present in the living room can use the toilet without being seen by others.

[0011]

In the present specification, for convenience, the right side (toilet front side) in FIGS. 1 and 2 is referred to as “front”, and the left side (toilet rear side) is referred to as “rear”. Also,
The right side (side wall side) in FIGS. 3 and 4 is called “right”,
The left side (the center of the room) is referred to as “left”.

As shown in FIGS. 1 to 4, in a house 2 built on the ground 1, a floor 3, a ceiling 4, a rear wall 5, a side wall 6, and other unillustrated parts. The living room 7 is formed by a wall, a shoji screen or a bran. In the living room 7, a toilet 8 that can be stored under the floor (hereinafter simply referred to as "toilet 8") is installed. Here, by pressing the up button of the toilet elevating switch 9, FIG.
And the toilet 8 as shown in FIG.
The (toilet) rises through a floor notch 3 a formed by cutting a part of the floor 3, and is exposed in the living room 7. When the down button of the toilet elevating switch 9 is pressed, as shown in FIGS. 2 and 4, the toilet 8 descends and is stored below the floor 3 (under the floor). Has become.

At the time of use of the toilet 8,
When the open button of the curtain opening / closing switch 10 is pressed, the curtain device 11 is automatically closed, and the toilet 8 and the user are hidden (shielded) by the curtain fabric 65 of the curtain device 11. When the toilet 8 is stored under the floor, the floor notch 3a is
The living room 7 is closed by the floor cutout 3a (the lid member 1).
It becomes a normal living room (the toilet 8 can not be seen at all) which can also use 2).

Hereinafter, the overall configuration of the toilet 8 will be described. Below the floor cutout 3a of the floor 3 having a rectangular shape (for example, 120 cm long and 90 cm wide), a box-shaped housing 13 that is open upward is arranged on the ground 1 (see FIG. 5). The housing 13 may be formed of any material having durability or corrosion resistance, for example, metal, resin (plastic), or the like.
As will be described in detail later, the lid member 12 is hinged to the upper end of the right side wall 39 (see FIGS. 7A and 7B) of the housing 13 so as to be rotatable.

The bottom wall 32 of the housing 13
On the loading surface (upper surface), a heavy object (for example, 30
(0 to 400 kg), and a lifting device 14 that can be raised and lowered is provided. The lifting device 14 has a loading surface slightly higher than the ground 1 in the vertical direction (the minimum ground clearance of the lifting device 14) and slightly higher than the upper surface of the floor 3 (the bottom wall of the movable base 15 described later). It can be moved up and down freely between the lower position (by the thickness). The elevating device 14 is an ordinary lift that is generally known, and is driven by an electric hydraulic unit by 28, and electric power is supplied through a conducting wire 29.

The movable platform 15 is placed on the loading platform of the lifting device 14.
Is arranged. The movable base 15 is a rectangle slightly smaller than the rectangular inner peripheral portion of the housing 13 in a plan view (see FIG. 6). Therefore, movable table 1

On the bottom plate 40 of the movable base 15 (see FIG. 6), a flush toilet 16 is arranged. The total height of the toilet bowl 16 is set to a value (for example, about 50 cm) such that the toilet bowl 16 is completely stored in the housing 13 when the bed surface of the lifting device 14 is at the lowest position. The toilet 16 is a normal household flush toilet, and a male can add a small toilet by flipping the toilet seat 17 up as shown by a virtual line. The toilet 16 has a hard tap water supply pipe 18 made of a hard material (eg, iron, polyvinyl chloride, etc.) and a tap water supply pipe 18 made of a soft material (eg, rubber, soft vinyl resin, etc.). Dirt is washed away with tap water received by the water tank 20 through the connected tap water supply hose 19. Here, the reason why the tap water supply hose 19 is formed of a soft material is to cope with the lifting and lowering of the toilet bowl 16 without any trouble. That is, when the toilet 16 moves up and down, the tap water supply hose 19 elastically changes its shape to cope with the elevation of the toilet 16.

The sewage is discharged to a sewer or a septic tank (not shown) through a drain passage having an inner pipe 21 and an outer pipe 22 each formed of a hard material (eg, iron, polyvinyl chloride, etc.). It has become. Here, the outer tube 22 is fixed to the ground 1 or the housing 13, the inner tube 21 is inserted into the outer tube 22 so as to be relatively movable in the vertical direction, and a clearance between the two is sealed as described later in detail. Have been. Then, when the toilet bowl 16 moves up and down, the inner pipe 21 moves up and down in the outer pipe 22 to cope with raising and lowering the toilet bowl 16 without any trouble. The outer peripheral portions of the inner tube 21 and the outer tube 22 may be covered with a skirt that can expand and contract in the vertical direction (for example, a skirt made of nylon cloth that expands and contracts in a lantern (accordion-like) shape).

Further, the toilet 16 is provided with a nozzle 23 for supplying water for hand washing as needed. Further, a paper holder 25 for holding the toilet paper 24 and a towel hanger 27 for holding a towel 26 are provided on the back surface of the lid member 12. When the lid member 12 is closed, the paper holder 25 and the towel hanger 27 are located on the left side of the toilet bowl 16 as shown in FIG.

Hereinafter, the components of the toilet 8 will be described in more detail. As shown in FIG.

When the cover 2 is closed, a groove (a portion where the lid member 12 is not present) or a gap is prevented from being formed above the side wall 39. That is, when the lid member 12 is closed (when the toilet is not used), the floor surface becomes flat, thereby preventing dust from entering. In addition, as is clear from FIG. 7B, when the lid member 12 is completely opened,
The inclined surface (lower end surface) of the lid member 12 and the inclined surface (upper end surface) of the side wall 39 of the housing 13 are in close contact.

As described above, the first vertical wall 41 of the movable base 15
Is provided with a rounded portion 45 at the upper right corner of the movable base 15 when the movable base 15 is raised.
Slides on the back surface of the lid member 12 and pushes the lid member 12 open naturally. Further, when the movable base 15 is lowered, the rounded portion 45 slides on the back surface of the lid member 12 with the downward movement, and the lid member 12 is naturally closed.

That is, as shown in FIG.
The straight upper end of the vertical wall 41 is the back surface (lower surface) of the lid member 12.
When it is located on the lower side, the first vertical wall 41 does not apply any force to the back surface of the lid member 12, so that the lid member 12 closes the floor cutout 3 of the floor 3. Here, as shown in FIG. 8 (b), after the upper end of the first vertical wall 41 is in contact with the back surface of the lid member 12, the rises as shown further by the arrow X _1, rounded portion 45 is a lid member contact with the rear surface 12, the lid member 12 is pushed up by the rounding unit 45, are opened and gradually rotates in the clockwise direction as indicated by the arrow X _2.

Then, as shown in FIG. 8C, when the first vertical wall 41 further rises, the rounded portion 45 does not come into contact with the back surface of the lid member 12, and the right end of the first vertical wall 41 has a linear shape. The surface starts to contact the back surface of the lid member 12. At this time, the lid member 12 is in the upright state, and the floor cutout 3a of the floor 3 is completely opened. Thereafter, even if the first vertical wall 41 further rises, the linear right end surface of the first vertical wall 41 and the linear back surface of the lid member 12 only slidably contact with each other. Keep state.

When the first vertical wall 41 descends from the state in which the lid member 12 completely opens the floor cutout 3a, the operation is the reverse of the case where the first vertical wall 41 rises. The member 12 closes the floor cutout 3a.

As shown in FIG. 9, an inner pipe 21 for discharging sewage from the toilet bowl 16 has a downstream end near an upstream end of an outer pipe 22 connected to a sewer or a septic tank (not shown). Has been inserted. Here, a first seal member 55 is attached to the outer peripheral surface near the lower end of the inner pipe 21,
The outer peripheral portion of the seal member 55 is in sliding contact with the inner peripheral surface of the outer tube 22. On the other hand, the inner peripheral surface near the upper end of the outer tube 22 has a second
The seal member 56 is attached, and the second seal member 5
The inner peripheral portion of 6 is in sliding contact with the outer peripheral surface of the inner tube 21. Therefore, a clearance portion (gap) formed between the outer peripheral surface of the inner tube 21 and the inner peripheral surface of the outer tube 22 corresponds to the first seal member 5.
5 and the second seal member 56, the sewage or odor is generated even when the inner pipe 21 is stopped or when the inner pipe 21 is moving vertically in the outer pipe 22. Does not leak outside. In addition, if the outer peripheral portions of the inner tube 21 and the outer tube 22 are covered with a skirt that can expand and contract in the vertical direction, the leakage of odor can be more completely prevented.

As shown in FIG. 10, the curtain device 11 extends along the front side (edge) and the left side (edge) of the rectangular cutout 3a in plan view, and at both ends, A substantially "V" -shaped pipe 60 is provided, the tip of which is curved so as to face a diagonal line connecting the front right corner and the rear left corner of the cutout 3a. The pipe 60 is fixed to the ceiling 4 using a plurality of fasteners 61 (see FIGS. 1 to 4). An endless rope 62 is accommodated in the hollow portion of the pipe 60. In addition, the rope 62
Is exposed in the living room because the pipe 60 does not exist between both ends of the pipe 60. Here, the rope 62
