DISCLOSURE OF THE INVENTION The conventional bathroom drainer described above has a box-shaped main body (for example, a width and length of 15 cm square) corresponding to the size of the bathroom (floor surface thereof). Body, length 30 cm, length 45 cm, length 6
Many 0 cm vessels etc. are manufactured. Therefore, it is necessary to manufacture not only the case-shaped main body but also the cover plate having various lengths, which is disadvantageous in that inventory control is troublesome and the manufacturing cost is high. Further, the conventional lid plate is formed of a flat metal plate (stainless plate). On the other hand, tiles are usually attached to the floor of the bathroom. Therefore, on the entire bathroom floor,
It is not acceptable because there is a sense of discomfort in design due to the difference in material between the tile surface and the cover plate (stainless steel plate) of the drainage device, and the presence position of the drainage device on the bathroom floor is particularly emphasized, which is not preferable. Furthermore, the conventional lid plate has a plurality of small holes (drainage holes) opened in the surface, and since each small hole is in an independent state, the drainage efficiency of sewage is extremely poor and sewage is pooled on the floor. There is a disadvantage to Further, when cleaning the bathroom, both a tile polishing agent for the floor surface and a stainless polishing agent (metal polishing agent) for the cover plate are required, and cleaning work is troublesome. Further, in the conventional drainage device, a separate trap projects downward from the bottom of the housing body. Therefore, the drainer itself becomes large, and the work of opening the prepared hole on the floor surface is troublesome, and there are disadvantages such that it is difficult to align the connection between the lower end of the trap and the sewer branch pipe.

The present invention solves the above problems and connects a plurality of base bodies fitted with a lid for accommodating tiles similar to the tiles constituting the bathroom floor to obtain a desired length. It is possible to obtain a drainage device of, and it becomes unnecessary to manufacture drainage bodies and lid plates of different sizes, and
It is an object of the present invention to provide a drainage device for a bathroom, in which the location of the drainage device cannot be seen at first glance and the drainage device has a high drainage efficiency as a result of the design of the drainage device fused with the bathroom floor surface.

[0006]

In order to achieve this object, the bathroom drainer of the present invention has the following structure. A bathroom drainer is a base body with upper and lower openings provided with bearing surfaces at appropriate places on the inner peripheral surface, and a rib that is fitted and arranged around the base body with a constant gap around the base body. A drainage body including a leg portion and a dish-shaped lid body having a tile placement accommodating portion similar to a bathroom floor tile on an upper portion, and a connecting member for connecting a plurality of the drainage body bodies in series. It is characterized by consisting of.

In the bathroom drainer having such a structure, the drainer body is composed of a base body and a dish-shaped lid body fitted and arranged in the base body. The dish-shaped lid is set so that a gap of about 5 mm is opened in the periphery when it is fitted to the base body, and the lid contains a single tile that constitutes the bathroom floor. The same tile is stuck and fixed. This base body has a rectangular shape with a width and length of 15 cm, corresponding to the size of the tile most often used on the bathroom floor. Drainers of different sizes are used depending on the size of the bathroom. If the bathroom is large, a plurality of, for example, four single drainage bodies (base bodies fitted with lids) are arranged in series. The connecting member that connects the drainage bodies includes, for example, a connecting hole portion provided on both end walls of each base body, and a connecting rod shaft fitted into the connecting hole portion. For each of the four drainage bodies, half the length of the connecting rod shaft is inserted into the connecting hole portion, and half the length of the connecting rod shaft that remains in the connecting hole portion of the adjacent drainage body is inserted. And connected in series. This makes it possible to obtain a drainage device having a length of 60 cm. Therefore, by connecting a plurality of drainers according to the size of the bathroom, a drainer of a desired length can be obtained, and the disadvantage of manufacturing drainers and lids of various lengths can be eliminated. Furthermore, in a state where a plurality of connected base bodies are fitted and attached to the floor surface drainage hole,
The tile surface attached to the dish-shaped lid of each base body is flush with the tile surface of the bathroom floor. Therefore, the bathroom floor surface becomes a unified tile surface including the lid part of the drainage device, and a total design structure can be realized. In other words, in the bathroom, the viewer is not made aware of the existence of the drainage device at all. Further, since the sewage on the floor surface is discharged from the fitting gap between the outer peripheral frame portion of each base body and (the tile of) the dish-like lid, that is, the continuous drainage gap that goes around the outer periphery of each dish-like lid, The amount of drainage is large and quick and high drainage efficiency can be obtained.

The dish-shaped lid 3 comprises a bottom plate portion 31 and a lid edge portion 32 fixed to the bottom plate portion 31 so as to be placed thereon.
In the embodiment, the dish-shaped lid 3 is formed in a flat rectangular tube shape having a width and length slightly smaller than 15 cm. The bottom plate portion 31 is made of a synthetic resin material (for example, ABS resin material) and has a horizontal plate shape. Rib leg portions (eight rib legs in the embodiment) 33 corresponding to the bearing surface portion 23 project downward from the bottom surface. It is set up. Further, the lid edge portion 32 is made of stainless steel, and is formed in a frame-like shape having an open upper and lower surface, which has a horizontal portion 32a and a vertical portion 32b and has an L-shaped cross section. This lid edge portion 32 is the bottom plate portion 3.
It is placed on the upper surface of the No. 1 and the overlapping portion of the horizontal portion 32a and the outer peripheral portion of the bottom plate portion 31 is fixed by thermal caulking. As a result, the tile placement accommodating portion 34 having the bottom plate portion 31 as the bottom surface and surrounded by the vertical portion 32b is formed. Further, on the outer surfaces of both side surfaces of the vertical portion 32b, there are attached lifting rotary plates 35 which are rotatably supported by pins 35a and which have openings 35b into which the fingertips are hooked and inserted. As shown in FIG. 2, when the dish-shaped lid body 3 is fitted in the base body 2 and the rib leg portions 33 are supported by the bearing surface portions 23, the upper ends of the vertical portions 32b and the frame body portion 24 are Are set to have the same height, and a fitting gap (a circumferential gap formed between fittings) C between the vertical portion 32b and the decorative frame body portion 24 is formed. That is, a continuous drainage gap C is formed around the outer periphery of the lid body 3. Furthermore, the same tile A as the single tile A that constitutes the bathroom floor surface is attached and disposed via the mortar B in the accommodation portion 34 of the dish-shaped lid 3, and the tile A in the accommodation portion 34 is The floor tile A and the floor tile A are flush with each other.

The feature of this invention is that a plurality of drainage bodies 1 are connected in series to obtain a drainage device of an arbitrary length. In the embodiment, as shown in FIG. 1, the connecting member 4 for connecting the plurality of drainage bodies 1 in series has a plurality of connecting members 4 provided on both end walls of the outer wall portion 21 of the base body 2 of each drainage body 1. The connecting hole portion (in the embodiment, three hole portions are formed on each end wall) 41, and the connecting rod shaft 42 fitted and inserted into the connecting hole portion 41. A plurality of connecting rod shafts 42 fitted and inserted into the connecting hole portions 41 are prepared in advance. The diameter of the connecting rod shaft 42 is slightly smaller than the diameter of the connecting hole portion, and the length is about twice the facing length between the outer wall portion 21 and the inner wall portion 22 of the base body 2. Is set to. That is, the connecting rod shaft 42 is set so that half the length thereof is fitted into the connecting hole portion 41 of the one base body 2 and the remaining half length is fitted into the connecting hole portion 41 of the adjacent base body 2a. (See FIG. 2).

In the bathroom drainer having such a structure, a plurality of single base bodies 2 are connected and used according to the size of the bathroom. For example, when the bathroom has a small area, two or three base bodies 2 are connected. When the area of the bathroom is large, for example, five base bodies 2 are connected.
In FIG. 3, the case where four drainage bodies 1 are connected is shown. The four drainage bodies 1 are arranged in series, respectively.
The connecting rod shaft 41 is fitted into the facing connecting hole portions 41 of the adjacent base bodies 2 and 2a as shown in FIG. That is, half the length of the connecting rod shaft 41 is fitted into one drainage body (the connecting hole portion 41 of the base body 2) 1 and the remaining half length is used for the other drainage body (for connecting the base body 2a). Hole 41)
Insert into 1. In this state, both base bodies 2, 2
Both end surfaces of a are in contact with each other, and both ends of the connecting rod shaft 42 are in contact with the outer surfaces of the inner wall portions 22, 22 of the base bodies 2, 2a, respectively. As a result, the four drainage bodies 1 are connected in series to form a long drainage device (see FIG. 3).
In addition, as shown in FIG. 2, a slight gap is formed in the upper portion of the connection portion of each drainage body 1. As shown in FIG. 4, this gap is on the same line as the tile joint on the floor surface of the tile, so that the mortar joint D is also filled in this gap. As a result, a drainer having a desired size corresponding to the size of the bathroom can be obtained. Therefore, it is not necessary to fabricate a drain plate of different sizes and a lid plate of different sizes. Further, as shown in FIG. 2, a dish-shaped lid 3 is fitted to each of the plurality of connected base bodies 2 (the rib leg portions 33 are mounted and fixed by being supported by the support surface portions 23). A tile A similar to the tile A forming the bathroom floor surface is fitted to the lid 3 via a mortar B, respectively. Then, the connected drainage devices (four base bodies 2) are fitted into the drainage pilot holes and fixed by mortar. In this fixed state, the upper surface of the tile A on the bathroom floor and the upper end of the frame body portion 24 are substantially flush with each other. Further, the upper end of the frame body portion 24 and the upper end of the lid edge portion (vertical portion 32b) 32 are flush with each other, and the frame portion 24
Between the fitting of the vertical portion 32b and the vertical portion 32b, that is, a continuous drainage gap C is formed on the outer periphery of each lid 3, and the floor tile A and the tile A of each lid 3 are flush with each other. ing. Therefore, the bathroom floor including the drain is entirely composed of the same tile A, and the drainage gap C corresponds to the joint between the adjacent tiles A and A on the floor. As a result, the presence of the drain is apparent. However, the drainage part is completely assimilated to the bathroom floor surface to form a total design structure of the bathroom floor surface (see FIG. 4).

The sewage on the floor of the bathroom flows in through the fitting gap between the frame portions 24 and the lid edge portion 32, that is, the continuous drainage gap C that goes around the outer circumference of each lid plate 3, and the inclined wall. Through the portion 22a and the inner wall portion 22, the water is directly drained to the drainage pilot hole, that is, the sewage branch pipe provided under the drainage pilot hole. Therefore, sewage does not overflow into the upper surface of the drainage part (tile A) on the floor of the bathroom. Further, since the wastewater is discharged from the continuous drainage gap C that goes around the outer circumference of each lid plate 3, the drainage area is extremely large, the drainage is quick, and the drainage efficiency is high.
There is no sense of filth such as dirt on the tile A surface such as hair loss. Even if filth collects in the drainage channel,
By raising the rotating plate 35 located in the drainage gap C, the dish-shaped lid 3 can be easily pulled out from the base body 2, and the inside can be easily cleaned.

Although the cover edge portion 32 and the frame body portion 24 are made of a decorative frame (made of stainless steel) in the embodiment, they are integrally made of the same synthetic resin material as the base body 2 and the bottom plate portion 31 at the time of implementation. The base body 2 and the bottom plate portion 31 including the lid edge portion 32 and the frame portion 24 may be integrally formed of stainless steel.

FIG. 5 is an explanatory perspective view showing another embodiment of the connecting member 4. The connecting member 4 shown above includes the connecting hole portion 41 and the connecting rod shaft 4 provided in the outer wall portion 21 of the base body 2.
2 is shown, but in this embodiment, the scissors plate 43 is attached to the outer wall portion 21 of the base body 2 from the lower side of the opening. The connecting member 4 is formed on a scissor plate 43 having a “U” -shaped cross section having a length substantially equal to the end face length of the base body (end wall of the outer wall portion 21). On both inner surfaces, projecting ridges 44 projecting inward are integrally provided. As shown in FIG. 6, with the outer wall portions 21, 21 of the adjacent drainage bodies 1, 1, that is, the adjacent base bodies 2, 2a in contact with each other, the scissors plate 43 is externally fitted from below. At this time, the outer wall portion 2 that faces
The ridges 44, 44 on the opening side are pushed outward by 1 and 21 to open the opening of the scissors plate 43. Then, when the lower ends of the outer wall portions 21, 21 that come into contact with each other are sandwiched to the bottom of the scissors plate 43, the outer wall portions 21, 2 that come into contact with the spring ridges 44
1 is clamped and fixed. Therefore, in the case of this embodiment, it is not necessary to provide the connecting hole portion 41 in the base body 2 as in the previous embodiment, and the plurality of base bodies 2 can be connected more simply by the scissors plate 43.

[0017]

As described above, according to the present invention, the dish-shaped lid body in which the same tile as the single tile constituting the bathroom floor is arranged in the vertical frame portion is fitted to the decorative frame portion of the base body. Since it was decided to connect a plurality of drainage bodies formed in series through a connecting member, a plurality of drainage bodies can be connected according to the size of the bathroom floor surface, and a drainer of a desired length can be obtained. You can get it. Therefore, it is possible to eliminate the disadvantages of manufacturing drainage bodies of different sizes and lids of different sizes. Moreover, since the outer surface of the rectangular tubular outer wall portion is a flat surface having a vertical outer surface, and the decorative frame body portion stands up parallel to the inner side of the outer wall portion, the outer surface of the outer wall portion of the adjacent drainage body body, etc. Your butt can be completely faced,
A stable connected state can be obtained. Further, the base body has a double structure including an inner wall portion and an outer wall portion, and since the inner wall portion receives inflowing sewage, the facing space portion between the inner wall portion and the outer wall portion is not directly related to the sewage flow passage. Therefore, since the connecting member is disposed in the facing space, it does not interfere with the drainage flow path of the dirty water, and there is no fear that the connecting member projects outside the drainage body. In addition, since the connecting member is provided so as to straddle the facing space of one drainage body and the facing space of the adjacent drainage body, the outer surfaces of the plate-shaped outer wall portions of both drainage bodies are firmly fixed. And, they can be connected in a stable close contact state. In addition, it is not possible to obtain a drainer of a desired length by connecting a plurality of drainage bodies in which a dish-shaped lid body is fitted to the base body, and sewage can be collected from a plurality of dish-shaped lid bodies. It is drained from the drainage gap that goes around the circumference. Therefore, compared with a single drainer having the same length as the connected length draining from the drain groove that goes around the outer circumference of the body, the drainage area becomes overwhelmingly large, resulting in quick and large drainage. Can be provided. Furthermore, by sticking the same tile as the single tile that composes the bathroom floor to the dish-shaped lid, the bathroom floor including the drain is the same tile, and the drainage gap is adjacent. As a result, which corresponds to the joint between floor tiles, the presence of the drainage cannot be seen at first glance,
It has the excellent effect of achieving the purpose of the invention, such as the drainage part being assimilated to the bathroom floor.
