Description

[Detailed explanation of the invention] (a) Industrial application field This invention relates to a floor storage box when a drain plug is installed under the floor.

(b) Conventional technology In the cold region of Hokkaido, water in water pipes often freezes during the winter. As a countermeasure to this problem, drain valves have been devised that drain the water from the pipes and drain them underground before going to bed, and these are commonly used. Figure 1 shows the installation status of a known water drain valve, where 1 is an outer pipe, 5 is a lower body, a water pipe 2 is connected to an inlet 3 in the lower body 5, and a riser pipe 7 is connected to an outlet 4. Further, a drain valve 6 is provided on the side part, and a faucet 8 is connected to the end of the riser pipe 7. Reference numeral 9 is a lever handle, and when the lever handle 9 is moved up and down, the valve piece inside the drain valve goes up and down, supplying water.
Turn off the water. In the case of water supply, water from the water pipe 2 is led to the riser pipe 7. In case of water stop, water pipe 2
Water from the riser 7 is blocked, while water from the riser 7 is discharged from the drain valve 6 into the ground below the freezing depth.
The above is the configuration of the known drain plug.

(c) Problems to be solved by the invention As shown in Figure 1, the lever handle 9 of the drain valve is often installed at a height of about 1 m from the floor 10 of kitchens, etc.; 10cm from
In some cases, they were installed at a height of 20 cm, but they sometimes got in the way and caused people to trip. In addition, it was sometimes placed in a position that was difficult for the operator to operate. Furthermore, there was a drawback that cold air could rise into the room because there was a gap 12 between the hole drilled in the floor and the outer shell pipe of the drain valve. Here, 11 is under the floor, 1
3 is the ground.

(d) Means for solving the problem The present invention focuses on this point and has the following configuration in order to embed the operating part of the drain valve under the floor and to block the cold air under the floor. In FIGS. 2 and 3, reference numeral 14 is a plate with a notch 20 in a part of the circular workpiece having a hollow hole into which one hand can fit, and a protrusion 19 of the circular lid 16 and a pin 1.
8, and the lid 16 is loosely fitted to the inner circumference of the plate 14.
It has a receiving part 22 for receiving. plate 14
A thin and flexible rubber shield cover 15 having a groove 23 around the lower outer periphery and a protrusion 24 around the upper inside thereof is fitted. As shown in FIGS. 3 and 7, the bottom of the shield cover 15 has a hole 25 smaller in diameter than the outer tube 1 of the drain valve. As another example, FIGS. 5 and 6 show a case in which the shape of the plate 14 and the lid 16 are rectangular.

(E) Action When operating the drain valve, as shown in Figure 4,
Open the lid 16, turn the lever handle 7 of the drain valve in the desired direction, and close the lid 16 after use. Therefore, except when operating the drain valve, the lid 16
Since the floor is level, it does not interfere with the room. In addition, the shield cover 15 is made of thin rubber,
Because it is flexible, the user's hands can move freely within the storage box even though the entire storage box is relatively small. In addition, since the hole drilled in the bottom of the shield cover 15 and the outer shell pipe 1 of the drain plug are in close contact with each other, cold air from under the floor does not rise to the floor.

(f) Effects of the invention As shown in Figure 8, since the operating section is provided under the floor, the location of the drain valve can be freely determined without interfering with the room. Furthermore, since the shield cover 15 is made of thin and flexible rubber, it can be handled even if the drain plug and the floor storage handle are slightly misaligned, and the shield cover 15 has the effect of preventing cold air from coming from under the floor.
