The water leak catcher 10 functions as a water leak catch structure by being installed in this way. Note that the drainage channel 40 is formed by connecting a plurality of cylindrical pipes, etc., and is well known, so a detailed explanation thereof will be omitted.

First, the specific structure of the receiving portion 20 will be explained with reference to FIGS. 2 to 8. This receiving portion 20 is made of, for example, polypropylene, which is a hard resin. The receiving portion 20 includes a receiving surface 21 that is a square with rounded corners when viewed from above. This receiving surface 21 has a uniform thickness and is inclined from each of the four sides toward the center downward. A cylindrical discharge port 22 is provided at the center of the receiving surface 21 and projects vertically downward in the up-down direction. A reduced diameter inner flange 23 is provided at the bottom of the discharge port 22.

A drain groove 24 is provided which is recessed downward from each of the centers of the pair of sides of the receiving surface 21 toward the outlet 22 and from each of the four corners toward the outlet. The drain groove 24 has a uniform rectangular cross-sectional shape in the longitudinal direction and the width direction.

A cylindrical attachment hole 25 is provided between the outlet 22 and each side of the receiving surface 21 where the drain groove 24 is not provided, and extends vertically through the receiving surface 21 in the up-down direction. An inner flange 26 having a reduced diameter is provided at the upper end of this mounting hole 25 . On each side of the outer periphery of the receiving surface 21, an upright wall 27 having a uniform thickness and height is provided that stands vertically upward along each side. In other words, the standing walls 27 provided on a pair of parallel sides of the receiving surface 21 constitute planes parallel to each other, and the standing walls 27 provided on the corner portions of the receiving surface 21 form parallel planes. It forms a curved surface that follows the shape of . At the upper end of this standing wall 27, a flange portion 28 is provided which is uniformly widened outward and has a uniform thickness.

The receiving portion 20 configured as described above is attached to the ceiling 100 by the attachment portion 30. The structure of this mounting portion 30 will be explained with reference to FIGS. 9 to 14. The mounting portion 30 includes a circular suction cup 31 made of vinyl chloride and having a concave center. The outer diameter of this suction cup 31 is smaller than the inner diameter of the inner flange 26 provided in the attachment hole 25 of the receiving part 20. Connected to the center of the suction cup 31 on the opposite side to the recessed side is a male threaded portion 32 having a spiral convex portion on the side surface of a cylinder.

The mounting portion 30 has a cylindrical tube portion 33, and a conical tube having a substantially truncated conical shape that shares one opening of the tube portion 33 and has an opening with a diameter smaller than the bottom at the opposite end. 34, a flange portion 35 provided with an enlarged diameter around the other opening of the cylindrical portion 33, and an annular annular convex portion 36 protruding from the flange portion 35 on the side opposite to the cylindrical portion 33 side. A cover portion 37 is provided. The outer diameter of the flange portion 35 is smaller than the inner diameter of the mounting hole 25 of the receiving portion 20 and larger than the inner diameter of the inner flange 26 provided in the mounting hole 25. The outer diameter of the annular convex portion 36 is slightly smaller than the diameter of the suction cup 31. Further, the side surface of the conical cylinder portion 34 is provided with unevenness that alternately continues in the circumferential direction and extends in the axial direction. A reduced diameter inner flange 38 is provided near the opening on the small diameter side of the conical cylinder portion 34 of the cover portion 37, and a spirally continuous female screw portion 39 is provided on the inner peripheral surface of the inner flange 38. is formed. The diameter of the female threaded portion 39 is such that it engages with the spiral convex portion of the male threaded portion 32.

How to attach the receiving part 20 to the ceiling 100 using the attaching part 30 configured as described above will be explained with reference to FIG. 15. First, the male screw part 32 connected to the suction cup 31 is passed through the mounting hole 25 of the receiving part 20. Subsequently, the cover part 37 is inserted into the mounting hole 25 from below, the male screw part 32 is engaged with the female screw part 39, and the cover part 37 is rotated. By rotating the cover part 37, the cover part 37 rises, the flange part 35 comes into contact with the lower surface of the inner flange 25, and the annular convex part 36 comes into contact with the suction cup 31. When the flange portion 35 abuts the lower surface of the inner flange 25 and the annular convex portion 36 abuts the suction cup 31, the rotation of the cover portion 37 is temporarily stopped, and the upper surface of the receiving portion 20 is brought into contact with the water leakage point 101 of the ceiling 100. The suction cups 31 are attracted to the ceiling 100 so as to face each other. Then, when the cover part 37 is further rotated, the male threaded part 32 is drawn into the female threaded part 9 and the suction cup 31 is pulled toward the cover part 37 side. As a result, the volume between the suction cup 31 and the ceiling 100 increases, the air pressure in that space decreases, the suction force of the suction cup 31 improves, and the receiving part 20 can be attached to the ceiling 100.

The side of the drain channel 40 connected to the receiving part 20 and the side connected to the through hole of the drain pipe are connected via a connector 50, respectively. Since this connector 50 is well known, it will be described with reference to FIGS. 16 and 17 while omitting the detailed shape. In this embodiment, the connector 50 will be described as being attached to a circular through hole 201 provided on the side surface of the rectangular cylindrical drain pipe 200.

The connector main body 51 has a generally cylindrical shape as a whole, and the outer shape of a portion thereof is approximately equal to the inner diameter of the drain channel 40 to which it is connected. Furthermore, a spiral threaded portion (not shown) that protrudes from the outer circumferential surface and rotates in the circumferential direction is provided on the outer circumferential surface near the longitudinal center of the connector main body 51. Further, a flange with an enlarged diameter is provided at the end opposite to the side connected to the drainage channel 40.

The nut body 52 has a cylindrical overall shape shorter than the connector main body 51, and is provided with an internal threaded portion (not shown) on its inner surface that engages with the threaded portion of the connector main body 51. The spacer body 53 has a cylindrical shape extending in the axial direction, and a flange with an enlarged diameter is provided at one end. The water stop body 54 has elasticity and has a cylindrical shape.

As shown in FIG. 18, the connector 50 configured as described above is configured so that the water stop body 54 is located inside the drain pipe 200, and the spacer body 53 is connected to the drain pipe 200 by turning the nut body 52. It can be attached by pressing it around 201. When the drainage channel 40 is removed from the connector 50, a bottomed cylindrical plug 55 is attached to the connector body 51 of the connector 50, as shown in FIG. This plug 55 has approximately the same inner diameter as the drain channel 40 attached to the connector 50, and by being attached to the connector 50, it blocks communication between the outside and the inside of the drain pipe 200 through the through hole 201. functions as a blocking means. In addition, if water leakage occurs again and it becomes necessary to reinstall the water leak receiver 10, the plug 55 is removed, the drain channel 40 is connected to the connector 50, and the water leak receiver 10 is installed.

The drain channel 40 connecting the receiver 20 and the drain pipe 200 is attached to the ceiling 100, a wall, etc. using a holder 60. This holding section 60 will be explained with reference to FIG. 20. The holder 60 includes a holder 61 and a base 62. The holding portion 61 is a member having an arcuate cross section, and its inner diameter is approximately equal to the outer diameter of the drainage channel 40 . The base 62 is a plate-shaped member, and is configured such that both ends of the arc of the holding portion 61 can be removably attached. The outer circumferential surface of the drain channel 40 is brought into contact with the inner circumferential surface of the holding part 61, and both ends of the arc of the holding part 61 are attached to the base part 62, so that the drain channel 40 is held by the holder 60.

This holder 60 has, for example, a suction cup (not shown) provided on the base 62, and is attached to a wall surface of a structure by the suction cup. Alternatively, the base portion 62 may be adhered to the wall surface of the structure or attached with adhesive tape. In this way, the drainage channel 40 can be removed from the holder 60 by removing the holding part 61 while leaving the base 62 on the wall surface of the structure or the like.

With the above configuration, the water leak catcher according to the present embodiment has the following effects.

- Since the receiving part 20 is attached to the ceiling 100 by the mounting part 30 provided with the suction cup 31, even when the ceiling 100 is wet due to water leakage, the water leakage receiving device 10 can be attached to the ceiling 100, and Since the ceiling 100 is not damaged during installation, new water leakage can be suppressed. In addition, even when trying to change the position of the water leakage catcher 10, there is no need to replace the attachment means such as adhesive tape or make a hole at another location on the ceiling 100. The position can be easily changed.

- When the suction cup 31 is attached to a wet area, the suction power is generally improved compared to when it is attached to a dry area. On the other hand, if water leakage continues, a load is applied to the receiving portion 20 due to the water leakage. Therefore, by attaching the receiving part 20 with the suction cup 31, a stronger suction force can be obtained when water leakage that requires more suction force continues, and when the water leakage stops and the ceiling 100 dries. That is, when the water leak catcher 10 is no longer needed, the suction force is reduced and the water leak catcher 10 can be easily removed.

- Since the discharge port 22 of the receiving part 20 is connected to the existing drain pipe 200 via the drainage channel 40, leakage water received by the receiving part 20 can be appropriately discharged.

- Since the receiving part 20 is attached by the plurality of attaching parts 30 so as to surround the discharge port 22, the load related to the attaching part 30 can be dispersed, and the falling of the receiving part 20 can be suppressed. Further, since the mounting portion 30 is mounted near the water leakage point 201 on the ceiling 100, that is, in a position that is likely to be wet, the suction force of the suction cup 31 can be improved.

- When removing the drainage channel 40, the holding part 61 can be removed from the base 62, so the drainage channel 40 can be easily removed. In addition, by attaching the base 62 in advance near the location where there is a risk of water leakage, or by leaving the base 62 attached to the structure after the water leakage has subsided, in the event of water leakage, The drainage channel 40 can be quickly installed. In addition, since the holding part 61 and the drainage channel 40 can be removed, if water leakage does not occur, it can be prevented from obstructing the passage of pedestrians, etc., and even if the base part 62 is left on the wall, it will not be noticeable. Because there is no such thing, it does not spoil the beauty of the aisle.

- When the drain pipe 200 is provided with the through hole 201, by opening the through hole 201, there is a risk that odor from the drain pipe 200 may leak to the outside through the through hole 201. In this regard, in this embodiment, since the stopper 55 is attached to the connector 50 when the drain channel 40 is removed, leakage of odor from the drain pipe 200 can be suppressed.

<Second embodiment>
This embodiment differs from the first embodiment in part in how the receiving portion 20 is attached to the ceiling 100. How to attach the receiving part 20 to the ceiling 100 in this embodiment will be explained with reference to FIG. 21.

A sheet 70 is pasted around the water leakage point 101 on the ceiling 100 before the receiving part 20 is attached. This sheet 70 is a gas-impermeable sheet made of resin such as polyethylene terephthalate, urethane, or silicone, or a gas-impermeable sheet made of metal. It may have a design similar to 100. The side of the sheet 70 opposite to the side facing the ceiling 100 is a smooth plane. Further, in order to be able to adhere along the curved ceiling 100, it may be necessary to be able to deform along a curved surface, so it is desirable that the thickness is to a certain extent that it can be curved. In addition, as shown in the examples of various resins used as materials, the gas impermeability function is not strict, and may be one that allows some gases to pass through, or may be permanent. You don't have to. In other words, it is sufficient as long as the suction cup can be prevented from coming off while water leaks. Then, the receiving part 20 is attached to the ceiling 100 by adsorbing the suction cup 31 of the attaching part 30 to the sheet 70.

Note that in the case where a suction cup is used to attach the base 62 of the holder 60 to the wall surface of a structure, the sheet 70 may be used as in the case where the receiving part 20 is attached to the ceiling 100.

With the above configuration, the water leak catcher 10 according to the present embodiment has the following effects in addition to the effects provided by the water leak catcher according to the first embodiment.

- Even if the ceiling 100 is uneven and it is difficult to attach the attachment part 30 with the suction cup 31, the receiving part 20 can be attached to the ceiling 100 with the suction cup 31 by pasting the sheet 70. In addition, by attaching the sheet 70 in advance near the location where there is a risk of water leakage, or leaving the sheet 70 attached after the leakage has subsided, it is possible to quickly attach the sheet 70 to the receiving area in the event of a water leakage. 20 can be attached.

- When the receiver 20 and the drainage channel 40 are removed, only the sheet 70 remains on the ceiling or wall, so if no water leakage occurs, it can be prevented from obstructing the passage of pedestrians, etc. . In addition, since the sheet 70 is generally inconspicuous, even if the sheet 70 is left on the ceiling, wall, etc., it will not spoil the aesthetic appearance of the passageway.

<Modified example>
- In the embodiment, the sheet 70 that can attract the suction cup 31 is attached to the ceiling 100, but the sheet 70 can be made of a material that can be magnetically attached, such as an iron plate, and a magnet can be provided on the attachment part 30 instead of the suction cup 31. Then, the receiving portion 20 may be attached. Further, the holder 60 that holds the drainage channel 40 may also be provided with a magnet, and may be magnetically attached to an iron plate or the like attached to a wall surface, the ceiling 100, or the like.

- In the embodiment, the drainage channel 40 is connected to the receiving part 20 and the through hole 201 via the connecting tool 50, but the drain channel 40 is connected directly to at least one side without using the connecting tool 50. Good too. When the drainage channel 40 is directly connected to the through hole 201, a shielding means capable of closing the through hole 201 may be separately provided.

- In the embodiment, the connection of the through hole 201 is blocked by attaching the stopper 55 to the connector 50, but water is allowed to flow into the connector 50 from the outside, and the inside A valve or the like may be provided to prevent air from flowing out from the outside. Further, the valve may have a structure that opens when the drainage channel is connected and closes when the drainage channel is removed.

- In the embodiment, the drainage channel 40 is connected to the discharge port 22 of the receiving part 20 via the connector 50, but the receiving part 20 and the drainage channel 40 may be formed integrally. Moreover, the receiving part 20 and the drainage channel 40 of a predetermined length are integrally formed, and a separate drainage channel 40 is connected so as to extend the drainage channel 40 as necessary. It may also constitute the whole.

- The structure of the holder 60 shown in the embodiment is merely an example, and various changes are possible. Any structure may be used as long as the state in which the drainage channel 40 is held by the member and the state in which it is held can be changed. For example, if it is necessary to maintain the drainage channel 40 at a position away from the ceiling 100 or wall, a hook-shaped member corresponding to the base 61 is attached to the ceiling 100, and a wire or the like attached to the hook-shaped member is attached to the ceiling 100 to drain water. The passage 40 may also be suspended. Further, a member corresponding to the base 61 may be attached to the wall surface or ceiling 100 with a suction cup, so that it can be easily installed and removed.
