Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a spout that is mounted on a horizontal deck board of a bathtub, washstand, sink, etc. so as to be rotatable in a horizontal plane.

[Conventional technology]

For example, a spout that is rotatably mounted on a deck board on the upper edge of the bathtub so that the spout does not get in the way of bathing or risk colliding with the body is disclosed in Japanese Utility Model Publication No. 59-385. There is a structure described in . To briefly explain this according to Fig. 6, there is a horizontal deck plate a on the upper edge of the bathtub.
The water supply pipe b is made to protrude upward, a male screw c is formed on the outer circumferential surface of the water supply pipe b, and a rotary shaft cylinder is attached to the base end of the water spout main body e, which has a water spout portion d to the bathtub at its tip. fix the rotary shaft cylinder f, hang the rotary shaft cylinder f into the water supply pipe b, and attach the rotary shaft cylinder f to the upper edge of the cover body j.

Note that m is a stopper fixed in the water supply pipe b to limit its rotation range, and n is a protrusion extending from the lower edge of the rotary shaft cylinder f so as to come into contact with the stopper. Further, o is a sheet-like packing placed on the lower surface of the cover body j, and p is a slip ring interposed on the upper surface of the cover body j.

[Disadvantages of conventional technology]

However, in a rotating spout constructed as described above, the spout body may rotate unnecessarily while spouting water due to reaction or vibration of the spout, or tilt of the spout body, etc. Also, for example, in bathtubs installed in hotel rooms, the rotating spout is always oriented in a direction that looks balanced with the bathtub or in the optimal water spout direction every time the bathroom is cleaned, so that the next user will have a good impression.
Conventionally, the water outlet body has had the disadvantage that it tends to wobble even when it is aimed in the required direction, making it difficult to keep it still in the optimum setting position.

[Purpose of invention]

The present invention aims to eliminate the above-mentioned drawbacks and provide a rotary water spout with excellent usability.

[Means to achieve the purpose]

In order to achieve the above object, the present invention provides a water supply pipe that protrudes upward from the horizontal deck board of a bathtub, washstand, etc., and connects the upper end of the rotary shaft cylinder with a flange on the outer periphery near the upper end to the water spout body. The cover body is screwed and fixed to the base end, and the rotary shaft cylinder is rotatably inserted into the water supply pipe, and the cover body is formed with a locking edge that engages with the collar, and is fixed on the deck board. In a rotary water spout, a fitting body is provided on one side of the facing portion of the cover body and the rotating shaft cylinder or the spout body, and a recess is provided on the other side, and the fitting body is provided with a spring and is fitted into the recess by the biasing force of the spring. The recess is designed so that it can be easily removed by rotating the spout main body against its elasticity, and the recess is located at a position where the spout main body faces at least the desired direction of a water storage tank such as a bathtub or wash basin within its rotation range. It is characterized in that the fitting body is provided so as to fit together.

[Effect]

If the fitting body fits into the recess when the spout main body is held in the hand and rotated, the shock is transmitted to the hand and more torque is required for the rotation operation. Therefore, by the sensation of a shock, it is easy to know that the spout main body is set in the optimum direction. At this time, the fitted state between the fitted body and the recess is maintained by the elasticity of the spring, but the fitted state can be easily removed from the recess by slightly increasing the rotational operating force against the elasticity of the spring. . Furthermore, if water is spouted while the fittings are held in the fitted state, it is possible to prevent the water spout main body from moving unnecessarily due to reaction or vibration.

〔Example〕

Next, a first embodiment of the present invention will be described with respect to a bathtub mixer faucet shown in FIGS. 1 to 5.

In the figure, 1 is a bathtub, and 2 is a horizontal deck board on its upper edge. Below the deck board 2 are a hot water faucet 3 and a water faucet 4.

The deck plate 2 is screwed together with the flange 14 and tightened to sandwich the deck plate 2. Reference numerals 18 and 19 indicate gaskets interposed between the respective clamping portions. Reference numeral 20 denotes a rotary shaft cylinder having a flange 21 formed on the outer periphery near the upper end, and 27 a spout main body to which the upper end 22 of the rotary shaft cylinder 20 is screwed and fixed at the base end. Reference numeral 23 indicates a water sealing O-ring disposed on the threaded portion thereof, 24, 24 O-rings fixed to the outer periphery of substantially the lower half of the rotating shaft cylinder 20, and 25 extending to the lower end of the rotating shaft cylinder 20. provided protrusion, 25,2
6 is a stopper fixed in the water supply pipe 10.
A recess 38 is formed on the outer circumferential surface of the approximately intermediate portion of the rotary shaft cylinder 20 at a position corresponding to the back surface of the spout main body 27, and recesses 39, 39 are also formed at positions corresponding to both side surfaces of the spout main body 27. ' is formed.
On the other hand, the cover body 28 is formed into a substantially rectangular box shape so as to cover the nut member 15 and the water supply pipe 10, and has a hooking edge 29 integrally formed with a small inner diameter at its upper opening. , screws 31, 31 are attached to the mounting pieces 30, 30 formed on the opposing inner wall surfaces.
An annular plate-shaped rotation stopper 32 is fixed horizontally. The rotation stopper 32 has an inner diameter that substantially matches the outer diameter of the water supply pipe 10, and has the non-circular portion 1 at an opposing portion.
Linear matching portions 33, 33 are formed that abut on the portions 3, 13. Further, a screw hole is provided below the back surface of the cover body 28, and a screw 34 is screwed into this screw hole. Further, a holder 40 having a bottomed cylindrical shape with an open end is screwed into a screw hole provided above the back surface of the cover body 28, and a coiled spring 41 and a spherical fitting body 42 are installed inside the holder. Then, the fitting body 42 is elastically protruded from the opening at the tip of the holder by the biasing force of the spring 41, and the fitting body 42 can be fitted into the recess 38 or 39, 39 on the outer peripheral surface of the rotating shaft cylinder 20. Do it like this. Incidentally, reference numerals 35 and 35 are supporting pieces that can come into contact with the outer peripheral surface of the nut member 15 that is integrally formed inside the cover body 28.

When the upper end 22 of the rotary shaft cylinder 20 is screwed into the base end of the spout main body 27, the cover body 28 engages the latch edge 29 on the collar 21 and slips onto the latch edge 29. 37 and screw it on. Then, the rotating shaft cylinder 20 is inserted into the water supply pipe 10 from its upper end opening, and the O-rings 24, 24 are brought into sliding contact with the inner surface of the water supply pipe 10 to make it watertight, and the rotation stopper 32 is fitted onto the outer periphery of the water supply pipe 10. Then, the nut member 15 and the water supply pipe 10 are hidden using the cover body 28. Then, the cover body 28 is fixed onto the deck plate 2 by screwing in the screw 34 and bringing its tip into contact with the annular groove 16.

In this rotary spout, the spout main body 27 is
As shown in the figure, it can be manually rotated in a horizontal plane so that it does not interfere with bathing. Its rotatable range is limited to approximately 180 degrees by the protrusion 25 hitting the stoppers 26, 26. When the spout main body 27 is rotated, the fitting body 42 fits into the recess 38 and a shock is transmitted to the hand, requiring more torque than before for the rotation operation. As shown by the solid line in FIG. 5, it can be seen that it is in a state facing the center of the water tank of the bathtub 1, which looks well-balanced with respect to the bathtub and is the optimal water discharge direction. By maintaining this fitted state, the water spout main body 27 can be prevented from turning sideways due to reaction or vibration during water spouting. This fitted state does not interfere with the rotational operation because the fitting body 42 can easily be removed from the recess 38 by slightly increasing the rotational operation force against the elasticity of the spring 41. Moreover, when the spout main body 27 is rotated to the side, the fitting body 4
2 fits into the recess 39 or 39' and can be maintained without interfering with bathing. Also, this recess 3
9 and 39' soften the shock applied to the stoppers 26 and 26 when the spout main body 27 is rotated vigorously to prevent damage thereto, and also prevent the spout main body 27 from returning forward due to the reaction.

Although this embodiment shows an example in which a recess is formed in the rotating shaft cylinder 20 and a fitting body is provided in the cover body 28, it is also possible to provide a fitting body in the rotating shaft cylinder 20 and to fit the fitting body into the inner surface of the cover body 28. A matching recess may be provided. Alternatively, a recess may be provided on the upper surface of the cover body 28, and a fitting body may be biased by a spring and provided at a portion of the base of the spout main body 27 that faces the upper surface of the cover body 28. In short, a fitting body may be provided on one of the facing portions of the cover body 28 and the rotary shaft cylinder 20 or the spout main body 27, and a recessed portion may be provided on the other.

[Effect of idea]

As explained in the embodiments above, according to the configuration of the rotary spout of the present invention, by fitting the fitting body into the recess, the spout main body can be seen in a well-balanced manner with respect to a water storage tank such as a bathtub, and the optimal water spouting direction can be determined. This is a useful feature that can significantly improve the usability of the rotary spout because it can be easily held in the desired direction and also prevents the spout main body from rotating unnecessarily from its holding position due to reaction or vibration of the spouting water. be.
