Description

DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION (Industrial Field of Application) The present invention relates to a pipe joint comprised of male and female pipe bodies for use in an oscillating discharge pipe.

(Prior Art) In unit baths and the like, a bathtub and a washstand are placed close to each other and placed side by side in order to make effective use of a narrow area. In this type of unit bath, by installing only one oscillating discharge pipe approximately midway between the bathtub and the wash basin, it is possible to use hot or cold water in both, and separate discharge pipes are provided for each. This has the advantage that the piping etc. can be simplified compared to the conventional case.

(Problem to be Solved by the Invention) For example, if you try to wash your hands in a washbasin while filling a bathtub with water, and you swing the discharge pipe towards the washbasin while it is still discharging water, the discharge pipe will When passing above the upper edge of the bathtub or above the upper edge of the washbasin, the discharged water scatters all over the area, resulting in flooding. To prevent this, the extremely troublesome method of turning off the water while keeping the discharge pipe pointing towards the bathtub, then swinging the discharge pipe toward the washbasin and discharging water again while adjusting the flow rate to an appropriate level. was necessary. For example, even in cases such as bathing, where it is acceptable for some hot water to splash around, the flow rate of water for replenishing water on the bathtub side and the flow rate of water for shaving, etc. on the wash basin side are the same. were significantly different, and in any case, it was necessary to adjust the flow rate after shaking the head.

The present invention has been made in view of the above-mentioned circumstances, and provides a new pipe joint for an oscillating discharge pipe that does not require troublesome adjustment of the water discharge flow rate and does not cause hot water to splash around. The purpose is to provide

"Structure of the Invention" (Means for Solving Problems) This specification discloses two inventions having the same main parts. The main parts common to both of these inventions include a cylindrical male tube whose open tube end is closed by a tube end partition wall, and a peripheral wall of the tube end partition wall of the male tube body within the open tube end. It consists of a female tube body that is rotatably fitted into the male tube body, and an orifice is bored in the peripheral wall of the male tube body, and an inner surface of the peripheral wall of the female tube body corresponding to the peripheral wall of the male tube body. A water passageway is recessed to communicate the peripheral area corresponding to the orifice temporarily drawn by the rotation of the male tube body and the external area of the tube end partition wall along the tube axis direction.

and the pipe joint according to the first invention (hereinafter referred to as the first invention)
(referred to as a pipe joint) consists of the above-mentioned main parts with the following constituent elements added. That is, in the peripheral wall of the male tube body, small holes are bored at circumferential sides of the mouth holes at water-stop intervals that are wider than the concave width of the passageway of the female tube body.

Further, the pipe joint according to the second invention (hereinafter referred to as the second pipe joint) has the following constituent elements added to the above-mentioned main part. That is, on the inner surface of the peripheral wall of the female tube body, a small water passageway is recessed in the circumferential side of the water passageway with a water stop interval wider than the opening width of the orifice of the male tube body. .

(Function) First, the first pipe joint of the present invention will be explained. Assume that a male pipe body is connected and fixed to a water supply pipe, and a discharge pipe is connected to the male pipe body. That is, when the discharge pipe is oscillated between the bathtub and the washbasin, the male pipe body rotates within the female pipe body. Now, with the discharge pipe facing the bathtub side, the mouth hole drilled in the peripheral wall of the male pipe body is aligned with a part of the water passage recessed in the inner surface of the peripheral wall of the female pipe body. Suppose there is. The water supplied into the pipe of the female pipe body first hits the outer surface of the pipe end partition wall of the male pipe body. Therefore, the air mass contained in the water is divided into smaller pieces, and the flow of the water is rectified. This eliminates the harsh sound of water flowing. In addition, the water that hits the pipe end partition wall of the male pipe body flows into the male pipe body through the opening hole from the water passage of the female pipe body located in the radial direction with respect to the pipe end partition wall. , is discharged from the discharge pipe into the bathtub. In other words, the water flow path formed from the female tube body to the male tube body, while flowing along the tube axis direction between the female tube body and the male tube body, once deviates from the tube axis direction and passes through the water passageway. They are starting to move around inside. Therefore,
The water hammer phenomenon caused by sudden operation of the handle to shut off the water is damped, and damage to the faucet equipment and impact noise are also prevented. Then, when the discharge pipe is swung from the bathtub side to the washbasin side,
The orifice of the male tube moves away from the water passage of the female tube, and the small orifice eventually comes to coincide with the water passage. Since the interval between the mouth hole and the small mouth hole is a water stop interval that is wider than the concave width of the water passage, the rotation period from when the mouth hole separates from the water passage until the small mouth hole coincides with each other, i.e. When the discharge pipe passes above the upper periphery of the bathtub or above the upper periphery of the basin, a water-stop state is maintained. Of course, when the discharge pipe faces the washbasin, the flow channel and the small opening match as described above, so the discharge volume is narrowed down to a small amount corresponding to the opening area of the small opening, and the discharge flow rate is deliberately reduced. There is no need to adjust. In addition, if the arrangement of the bathtub and washbasin is opposite to the above, the first pipe joint should be turned upside down and the male pipe body connected and fixed to the water supply pipe, and the female pipe body should be connected and fixed to the water supply pipe. A discharge pipe may be connected to the body. In this case, the water is
As the flow begins to flow from the male tube to the female tube, the inner surface of the male tube ends against the partition wall of the male tube. This is the same as above, and the point that the flow is then once deviated from the tube axis direction through the mouth hole and water passage is also the same, so there is no difference in its operation.
In addition, in this second pipe joint, there is one opening hole drilled in the male pipe body, and two large and small water passages recessed in the female pipe body. The action is almost the same as that of the first pipe joint.

(Example) The present invention will be described below based on drawings showing examples thereof.

FIG. 1 is a partially cutaway perspective view of the first pipe joint of the present invention. The first pipe joint of the present invention consists of a male pipe body 1 and a female pipe body 2 which are formed into a cylindrical shape.

As shown in FIG. 2, the open tube end of the male tube body 1 is closed by a tube end partition wall 1b. As shown in FIG. 1, a mouth hole 3a and a small mouth hole 3b having an opening area smaller than the opening area of the mouth hole 3a are bored in the peripheral wall 1a surrounding the pipe end partition wall 1b. ing.

The female tube body 2 has an inner diameter that is approximately the same size as the outer diameter of the male tube body 1, so that a watertight fitting relationship can be obtained with the peripheral wall 1a of the male tube body 1. I get used to it and feel at ease. A passageway 4 is recessed in the inner surface of a peripheral wall 2a of the female tube body 2, which corresponds to the peripheral wall 1a of the male tube body 1. As shown in FIG.
When the body rotates, the mouth hole 3a and the small mouth hole (not shown) of the male tube body 1 are formed on the inner surface of the peripheral wall 2a of the female tube body 2.
The corresponding peripheral area tentatively drawn by the male tube body 1 and the external area of the tube end partition wall 1b of the male tube body 1 are formed so as to communicate with each other along the tube axis direction.

FIG. 3 is a plan sectional view showing the fitted state of the male tube body 1 and the female tube body 2. As shown in the figure, the distance between the mouth hole 3a and the small mouth hole 3b of the male tube body 1 is wider than the concave width of the water passage 4 in the female tube body 2. That is, when the water passageway 4 of the female tube body 2 is located in the water-stop interval between the mouth hole 3a and the small mouth hole 3b, the communication state between both the tube bodies 1 and 2 is cut off. The opening area of the mouth hole 3a in the male tube body 1 is set to allow the passage of the maximum amount of water generally required by a faucet or the like. Also, small hole 3
The opening area of b is narrowed so that when water is discharged into a shallow bottom area such as a washbasin, the flow rate is such that the water that bounces off the bottom does not scatter to the surrounding area.
The structure for preventing the male tube body 1 and the female tube body 2 from coming off, as shown in FIG. However, the structure is not limited to that shown, and various conventionally known structures may be adopted.

The usage status of this first pipe joint will be explained. first,
As shown in FIG. 4, in a unit bath or the like in which a bathtub 11 and a washbasin 12 are arranged side by side,
As shown in FIG. 5, the female pipe body 2 of the first pipe joint of the present invention is connected to the water supply pipe 7 which is protruded approximately midway between the water supply pipe 7 and the washbasin 12. Here, the male tube body 1 is rotated with respect to the female tube body 2 so that the passageway 4 of the female tube body 2 and the mouth hole 3a of the male tube body 1 are aligned. In this state, the male pipe body 1 is aligned so that the discharge pipe 6 faces into the bathtub 11 as shown in FIG.
Connect the discharge pipe 6 to. In addition, by doing this, the discharge pipe 6 can be connected to the wash basin 12 as shown by the two-dot chain line.
When the male tube body 1 is swung to the side, the small opening 3b of the male tube body 1 will be aligned with the passageway 4 of the female tube body 2.

When water is supplied from the supply pipe 7, the water flows from the water passage 4 of the female pipe body 2 through the mouth hole 3a of the male pipe body 1 and into the male pipe body 1, as shown by the arrow in FIG. and is discharged from the discharge pipe 6 into the bathtub 11. When the discharge pipe 6 is swung while still discharging water, the orifice 3a of the male pipe body 1 opens as shown in FIG.
The female pipe body 2 separates from the passageway 4 and becomes temporarily water-stopped. When the discharge pipe 6 continues to swing, the small opening 3b of the male pipe body 1 is connected to the water passage 4 of the female pipe body 2 when the discharge pipe 6 is just facing the washbasin 12. It will match. Therefore, water supply pipe 7
Water flows from the water passage 4 of the female pipe body 2 through the small opening 3b of the male pipe body 1, and is discharged from the discharge pipe 6 into the washbasin 12. The water discharged into the washbasin 12 is throttled by the small opening 3b of the male tube body 1, so that it has an appropriate flow rate.

FIG. 6 is a partially cutaway perspective view of the second pipe joint of the present invention. As shown in the figure, the main difference between the second pipe joint and the first pipe joint is that only one opening 3 is formed in the peripheral wall 1a of the male pipe body 1, and the opposite female The inner surface of the peripheral wall 2a of the tube body 2 is provided with a water passage 4a and a small water passage 4b having a smaller volume than the water passage 4a.
In the present second pipe joint, the volume of the water passage 4a in the female pipe body 2 is such that it can pass the maximum discharge amount of water generally required for faucets, etc. When water is discharged into a place with a shallow bottom, such as a washbasin, the flow rate is narrowed to a level that prevents water from bouncing off the bottom and scattering to the surrounding area. Further, the interval between the water passage 4a and the small water passage 4b is a water stop interval wider than the opening width of the mouth hole 3 in the male tube body 1. Other structures and functions are substantially the same as those of the first pipe joint, so a detailed explanation of the second pipe joint will be omitted.

(Study of another aspect) The opening shape of the mouth hole (and small mouth hole) and the concave shape of the water passage (and small water passage) can be changed depending on the water discharge situation due to the swinging of the discharge pipe. In other words, by making the opening shape of the orifice and the concave shape of the water passage into a vertically elongated shape, the area in which water can be discharged by the discharge pipe becomes narrow, and fine adjustment of the flow rate becomes impossible. On the other hand, by making the opening shape of the mouth hole and the concave shape of the water passage oblong, the area where water can be discharged by the discharge pipe becomes wider (for example, while the discharge pipe is located in the upper part of the bathtub, )
At the same time, the water discharge flow rate can also be adjusted by subtle rotation of the discharge pipe. In addition, the distance between the mouth hole and the small hole in the first pipe joint, the water stop interval between the water passageway and the small waterway in the second pipe joint, are determined by the mutual distance between the bathtub and the washbasin, and the discharge distance. This is determined by the length of the tube neck, etc. In addition, the present invention
Needless to say, it can be used not only in places where a bathtub and a wash basin are installed side by side, but also in a two-tank sink, a washing machine, etc. In this way, the detailed shapes and configurations of the first pipe joint and the second pipe joint can be changed as appropriate depending on the embodiment.

"Effects of the Invention" As is clear from the above explanation, according to the pipe joint for an oscillating discharge pipe according to the present invention, compared to the conventional art,
The cumbersome tasks of stopping water spouting, swinging the discharge pipe, starting water spout, and adjusting the flow rate are now as simple as simply swinging the discharge pipe, and the effect is tremendous. Of course, until the discharge pipe reaches the desired water discharge position, the water remains in a stopped state, so that the discharged water does not scatter around the upper edge of the bathtub or washbasin. In addition, it has the revolutionary advantage of eliminating the sound of flowing water and damping the water hammer phenomenon. Furthermore, a male pipe body for the water supply pipe and the discharge pipe,
By changing the connection relationship of the female pipe body up and down, the magnitude relationship of the amount of water discharged can be easily changed. There are many advantages such as there is no need to manufacture a separate model in which the positional relationship between the water passageway and the small waterway is reversed, and it is suitable for mass production.
