Description

[Detailed description of the invention] (a) Industrial application field This invention allows water to flow from the faucet when the user pulls it up to a predetermined position in the summer or during use, and in the winter or after use, the user can reduce the amount of water. A storage type water faucet for cold regions that prevents the water faucet from freezing in the winter and eliminates dead space in the summer by storing it in the faucet box, making it possible to use a water faucet box that is smaller than the current one. It is related to.

(B) Conventional technology As shown in Figure 1, outdoor water faucets include a water faucet type in which a faucet 1 is located below the ground level and a vinyl hose 2 or the like is connected to it to supply water.
Stand-type faucets, in which the faucet 1 is located a certain distance from the ground, as shown in FIG. 2, are widely used. In addition, to compensate for the drawbacks of these two types, a type is being considered that shrinks and becomes smaller when not in use, and automatically expands due to water pressure when water is passed through it during use. In addition, in a cold region like Hokkaido, the water in the riser pipe 3 during winter will freeze unless it is drained into the ground from the drain valve 5, which is below the freezing depth using the drain valve 4, and the water in the riser pipe 3 will freeze. This may cause damage to the product. Therefore, in addition to the faucet 1 and the riser pipe 3, an operating part 7 of the drain valve 4 is installed in the water faucet box 6. Here, 24 indicates a water pipe and 25 indicates a bucket.

(c) Problems that the invention aims to solve In the type shown in Figure 1, the faucet 1 is located below the ground level, so it cannot be used properly unless it is connected to a vinyl hose 2, etc., and when turning on and off the water, it cannot be used properly. It is very inconvenient to use because you have to bend down to do it. The type shown in Figure 2 has the advantage of being easy to use because the faucet 1 is installed at a height that takes into account the user's working posture, but since it always protrudes above the ground, it takes up a large amount of dead space on the site.
Furthermore, corrosion due to rain and snow increases. In addition, automatic extension types using water pressure have the disadvantage that if the water pressure is high, they will extend at a very high speed and there is a risk of the user hitting the faucet, while if the water pressure is low, they will not extend smoothly.

In a cold region such as Hokkaido, as mentioned above, in addition to the faucet and riser pipe, the operating part for the drain valve is also installed in the water faucet box, so a larger water faucet box is required. In order to eliminate the above-mentioned drawbacks of known products, the present product allows the user to supply water by pulling up the faucet to a specified height only when using it, so the faucet can be used like an automatic extension type. There is no risk of hitting people, and when not in use, the user can push the faucet down into the faucet box to eliminate dead space, and at the same time, the water in the riser pipe can be drained underground below the freezing depth, making it ideal for winter use. To provide a storage type water faucet for cold regions which can be made into a smaller water faucet box since there is no need to drain water again for a period of time and an operation part for the water drain faucet is also unnecessary.

(d) Means for Solving the Problems As shown in FIG. 3, the product of the present invention consists of a faucet 1, riser pipes 3A and 3B, an upper body 8, and a lower body 9.
The lower body 9 has a water pipe attachment part 10 and a drain valve 5 on the side, houses a piston 14 surrounded by O-rings 11, 12, 13 inside, and has a riser pipe 3B on the upper part. They are screwed together. An upper main body 8 fitted with a gasket 15 is screwed into the upper part of the riser pipe 3B. The shaft 1 is located above the piston 14.
6 are screwed together, and a shaft hanger 17 is screwed onto the upper part of the shaft 16. An elbow 18 is screwed into the upper part of the riser pipe 3A, a faucet 1 is screwed into the tip thereof, and a sleeve 19 is screwed into the lower part.
The sleeve 21 is assembled with a slight gap between the upper body 8, the riser pipe 3B, the shaft suspension 17, and the shaft 16 so that it can pass freely therethrough.

(E) Action Figures 4 and 6 are views of the product of the present invention in its reduced size and drained state by pushing down the faucet 1. By pulling up the faucet 1 from this state, the riser pipe 3A and the sleeve 19 also rise, and the upper part of the sleeve 19 comes into contact with the upper body 8. The sleeve 19 pulls up the shaft suspension 17 a predetermined distance from just before the sleeve 19 contacts the upper body 8 until it contacts the upper body 8. Shaft hanging 17 is shaft 1
6, and since the shaft 16 is threaded with the piston 14, the piston 14 also rises a predetermined distance,
Since the O-ring 11 separates from the valve seat 20, water flows through the water pipe fitting 10 towards the faucet 1. This is shown in FIGS. 3 and 5. Next, when the faucet 1 is opened and the faucet 1 is pushed down from the state shown in FIGS. touches the top of the When pushed down further, the large diameter portion 21 of the piston 14 in FIG. 3 comes into contact with the abutting portion 22 of the lower main body 9 and stops. This is the fourth
This is the state shown in FIG. O-ring 1 for tap water
1 and 12, and the water in the riser pipes 3A and 3B is discharged into the ground below the freezing depth through the hole 23 made in the piston 14 and the drain valve 5.

(f) Effects of the invention The product of this invention eliminates the risk of the faucet hitting the user, unlike automatic extension types that use water pressure, and eliminates dead space when deflated when not in use.
Since the water in the riser pipe also drains, there is no need to drain the water again, and therefore, there is no need for an operating part for the drain valve.
