Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a structure for attaching a perforated plate to a drainage part of a bathroom vanity or the like.

[Background technology] If hair flows into the drain pipe of a bathroom vanity with a shower, it will stick to the inner surface of the drain pipe and cause the drain pipe to become clogged. It is necessary to capture it and prevent it from flowing into the drain.
A conventional perforated plate 5 is shown in FIG. In this conventional perforated plate 5, a plurality of protrusions 9' are provided radially protruding from the outer periphery, and hair is also caught in the protrusions 9', but the protrusions 9' are horizontal. Since it was plate-shaped, when moving the perforated plate 5 up and down,
There was a problem in that the horizontal plate-shaped protrusion 9' caught on the sink area A formed on the inner surface of the upper part of the cylindrical drainage body 4, making it difficult to move the perforated plate 5 up and down. That is, the drainage body 4 has an outer flange 3 at the upper part and is made of synthetic resin, and therefore, due to shrinkage during molding, a fifth part is formed on the upper part of the inner periphery of the drainage body 4 on the opposite side to the outer flange 3.
This results in a sink area A as shown in Figure b, and the horizontal plate-like protrusion 9' gets caught in this sink area A, thereby impeding the smooth vertical movement of the perforated plate 5. In addition, to explain in more detail the attachment part of the conventional perforated plate 5, the upper end of the cylindrical part 11 is provided through the central part of the perforated plate 5, and the outer periphery of the lower end of the cylindrical part 11 is provided. A plurality of hair-collecting protrusions 12 extend radially, and the hair-collecting protrusions 1
A placing part 6 hangs downward from the tip of the drain body 4, and the placing part 6 is placed on a locking part 8 protruding from the inner surface of the drain body 4. A vertical bar 15 is fitted into the cylindrical portion 11 so as to be movable up and down, and a drain plug 16 is attached to the upper end of the vertical bar 15.
is fixed thereto, and when the drain plug 16 moves downward, the drain plug 16 fits into the upper end opening of the drain body 4 and blocks the upper end opening. In the figure, 26 is a metal cover. Note that the vertical movement of the drain plug 16 and the vertical movement of the perforated plate 5 are as follows.
The present invention will be described in detail in the description of the embodiments of the present invention, which will be described later, based on the overall cross-sectional view of the present invention shown in the figures.

[Purpose of the invention] The present invention was devised in view of the above points, and its purpose is to provide a sink area that protrudes on the outer periphery of the perforated plate in the sink area that occurs on the inner surface of the upper part of the synthetic resin drainage body. To provide a mounting structure for a perforated plate in which a protruding part is hard to get caught and the perforated plate can be moved vertically smoothly.

[Disclosure of the invention] The mounting structure of the perforated plate of the present invention is a cylindrical drain made of synthetic resin that is inserted into the hole 2 at the bottom of the container 1 and attached by placing the outer flange 3 on the upper outer periphery against the upper edge of the hole 2. The perforated plate 5 is fitted into the body 4 so that it can be pulled out upwardly, and the mounting part 6 provided at the lower part of the perforated plate 5 is placed on the locking part 8 protruding into the drainage body 4.
A plate-shaped inclined protrusion 9 inclined with respect to the perpendicular line on the outer periphery of
By adopting such a configuration, the above-mentioned object of the present invention is achieved. That is, in the present invention, by making the protruding portions that protrude radially from the outer periphery of the perforated plate 5 into plate-shaped inclined protrusions 9 that are inclined with respect to the perpendicular line, the protruding portions protruding from the outer periphery of the perforated plate 5 The part is less likely to get caught in the sink part formed on the inner surface of the upper part of the drainage body 4, and the perforated plate 5 can be moved up and down smoothly.

The present invention will be explained in detail below with reference to Examples. FIG. 1 shows an overall sectional view of the present invention. The cylindrical drainage body 4 is made of synthetic resin, and has an outer flange 3 integrally formed on the outer periphery of its upper end. Above drainage body 4
is inserted from above into a hole 2 at the bottom of a container 1, such as the bowl of a bathroom vanity, and is attached by fastening with the outer flange 3 in contact with the inner surface of the container 1.
Since this attachment is the same as the attachment of the conventionally known drainage body 4, the details will be omitted. The inner periphery of the opening at the upper end of the drainage body 4 is shaped like a tangle such that the diameter increases as it goes upward. The perforated plate 5 is approximately disk-shaped and has water holes 10 radially bored inside, and a plurality of protruding portions protrude radially from the outer periphery of the perforated plate 5, and each of these protruding portions is perpendicular to the perpendicular line. It has an inclined plate shape and forms an inclined protrusion 9. The inclination angle α of the inclined protruding piece 9 is 10° or more. In the embodiment shown in FIG. 2, the slanted plate-like slanted protrusion 9 does not protrude above the upper end of the perforated plate 5, but as shown in FIG. It may be made to protrude. The upper end of a cylindrical portion 11 extends through the center of the perforated plate 5, and a plurality of hair-collecting protrusions 12 extend radially from the outer periphery of the lower end of the cylindrical portion 11. A placing part 6 hangs downward from the tip of the hair collecting protrusion 12, and the placing part 6 is placed on a locking part 8 protruding from the inner surface of the drain body 4. A vertical bar 15 is fitted into the cylindrical portion 11 so as to be movable up and down, and a drain plug 16 is fixed to the upper end of the vertical bar 15. When the drain plug 16 moves downward, the drain plug 16 closes the drain body 4. It is designed to fit into the upper end opening of and to cover the upper end opening. An enlarged portion 17 is fixed to the lower end of the vertical bar 15. The enlarged part 17 is larger than the diameter of the hole in the cylindrical part 11, and when the drain plug 16 is pinched with fingers and pulled upward to be removed, the enlarged part 17 hits the lower end of the cylindrical part 11 and is pushed upward. The perforated plate 5 is removed from the drain body 4 along with the drain plug 16. The hair collected on the perforated plate 5 and the hair collecting protrusions 12 provided on the perforated plate 5 can be removed. A drain pipe 18 is connected to the lower end of the drain body 4, and a lateral projecting pipe 19 projects from the upper part of the drain pipe 18. A locking rod 20 is fitted into the side projecting tube 19, and a spherical portion 21 provided on the locking rod 20 is rotatably installed inside the side projecting tube 19, and a spring 22 pushes the spherical portion 21 into place. 23 prevents water from leaking outward from the side projecting pipe 19. One end of the tightening rod 20 is the ampulla 17
The lower end of the operating rod 24 is rotatably supported at the other end of the locking rod 20, and the operating knob 25 is provided at the upper end of the operating rod 24. The knob 25 protrudes from the top surface of the vanity counter, and by pinching the operating knob from the top surface of the counter with your fingers and moving it up and down, the knob 20 seesaws up and down centering on the spherical part 21, causing a huge amount of movement. Lift up part 17,
Alternatively, the lifting of the ampulla 17 is released. However, the ampulla 17 is the hard rod 20
As shown in FIG.
When the pushing up of the enlarged portion 17 by the drain plug 16 is released, the drain plug 16 falls downward due to its own weight and closes the upper end opening of the drain body 4. By the way, when the perforated plate 5 is pulled up together with the drain plug 16 in order to remove the hair collected on the perforated plate 5 and the hair collecting protrusion 12 provided on the perforated plate 5, or when the perforated plate 5 is refitted, the perforated plate 5 Since the projecting portion projecting outward from the outer periphery of the drain body 4 is the inclined protrusion 9 that is inclined with respect to the perpendicular line, it moves up and down while being guided along the slope of the outer edge of the inclined protrusion 9.
Even if there is a sink area on the inner surface of the upper end due to shrinkage during molding, smooth vertical movement is possible.

[Effects of the invention] As described above, in the present invention, since a plurality of plate-shaped inclined protrusions are provided at intervals on the outer periphery of the perforated plate, the plate-shaped inclined protrusions are The sloping part of the side edge acts as a guide when moving up and down, and the protruding part from the outer periphery of the perforated plate is less likely to get caught in the sink area that forms on the inner surface of the upper part of the drainage body, allowing for smooth vertical movement of the perforated plate. It is.
