Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet spout, and more particularly, to a faucet body disposed below a horizontal deck plate such as a bathtub or a washbasin, which is rotated on the deck plate. The present invention relates to a rotary spout that can be freely attached.

[0002]

2. Description of the Related Art A so-called flush-type faucet, in which a water outlet is provided on the deck plate with respect to the faucet body arranged on the lower side of the deck plate, controls the amount and temperature of water on the deck plate. Since only the handle to be adjusted and the spout for discharging adjusted hot and cold water are exposed, not only is the design of the bathtub or washbasin clean, but it is also convenient in use. Further, in this type of embedded faucet, it is also possible to freely change the discharge position of the hot water by making the water discharge port rotatable.

An example of such a rotary spout of an embedded faucet is a "bath spout" proposed in Japanese Utility Model Publication No. 59-385. In this spout, as shown in FIG. 7, in order to prevent backlash of the spout body C, a rotary shaft cylinder 30 screwed to the base end portion of the spout body C is connected to the connecting portion 7 of the plug body.
The cover 31 that is fitted into the inside of the water discharge port main body C and locked by the collar 32 of the rotary shaft cylinder 30 is screwed onto the male screw 39a formed on the outer periphery of the connecting portion 7, and the bathtub upper edge surface B is formed. The water spout main body C is brought into contact with (hereinafter referred to as a deck plate)
Is connected to the faucet body A.

The conventional bathtub spout C shown in FIG. 7 can be prevented from rattling, that is, can be prevented from tilting, but it has the following drawbacks. It is what

That is, in this conventional bathtub spout,
The packing 34 is fitted in an annular groove provided on the outer periphery of the lower portion of the rotary shaft cylinder 30 in the drawing, and the packing 34 is fitted together with the fitting into the connecting portion 7 of the rotary shaft cylinder 30. The side rotating shaft cylinder 30 and the connecting portion 7 are sealed. On the other hand, the cover 31 is hooked by the hooking piece 36 formed on the upper end thereof to the flange 32 of the rotary shaft cylinder 30 which is integrally screwed to the water outlet body by the male screw 33a. The rotary shaft cylinder 30 is almost entirely covered.

If the rotary shaft cylinder 30 and the cover member 31 covering the rotary shaft cylinder 30 are in the above-described relationship, in consideration of workability when the packing 34 is inspected and replaced, as shown in FIG. The shaft cylinder 30 has to be largely projected from the lower end of the cover body 31, and as a result, the rotation shaft cylinder 30 must be longer than that in order to prevent the rattling.

As described above, when the rotary shaft cylinder 30 is longer than necessary, not only the material is wasted, but also the entire embedded faucet becomes large and heavy, and the workability is deteriorated. This is uneconomical as a result.

As shown in FIG. 6, the rotary spout of this type has a faucet body, a first faucet body provided with a handle for adjusting the temperature and flow rate of hot water, and the first faucet. The main body and a second faucet body connected by a flexible pipe or the like may be separately provided and then connected to the second faucet body. The reason for dividing the faucet body into two, as in the example of FIG. 6, is
This is because there is a case where it is desired to separate the position of the spout from the position of the handle largely, and in this case, the second faucet body to which the rotary spout is connected is made relatively small.

If the rotary spout connected to the second water faucet body shown in FIG. 6 is a conventional one as shown in FIG. 7, for example, in order to inspect the packing 34, etc. , The cover member 31 is removed and the rotary shaft cylinder 30 is connected to the connecting portion 7.
As soon as it was pulled out of the deck, the second faucet body could no longer be supported by the deck board and would fall from the deck board. On the contrary, when the rotary water spout is attached to the second faucet body of this type, the second faucet body must be supported so as to be always in contact with the lower surface of the deck plate. Since there is not such a large space below the deck board, it is very difficult to inspect and install the rotary spout in this case.

Therefore, the present inventor has completed the present invention as a result of various studies on how to solve the above-mentioned difficulties in the rotary spout of this type.

[0011]

10 is a first water faucet body 211 and a second water faucet body 211 as shown in FIG.
The case where the faucet body 212 is divided will be described.

In the case where the faucet body 210 is of an integrated type, first, the amount of protrusion of the water supply pipe 40 onto the deck plate 50 is determined by the nut 42, and then, as shown in FIGS. Each water stop plug 60 is assembled to the deck board 50 so that the handle 61 is exposed on the deck board 50. As a result, the water supply pipe 40 protrudes from above the deck plate 50 between both the water stop plugs 60, so that the lower cover 32 is screwed to the deck plate 50 as shown in FIG. Of course, the seal member 22 is provided inside the lower part of the lower cover 32.
The seal member 22 seals between the upper end portion of the water supply pipe 40 and the lower cover 32 by being screwed onto the water supply pipe 40.

The above-described screwing of the lower cover 32 to the water supply pipe 40 may be performed prior to the attachment of the respective water stop plugs 60 described above. In this case, if the lower cover 32 is screwed from the upper side of the deck plate 50 to the water supply pipe 40 whose protrusion amount to the deck plate 50 is regulated by the nut 42, the faucet body 210 is attached to the lower surface of the deck plate 50. Since the water stopper body 210 can be temporarily fixed and will not drop, the assembly of each water stopper 60 is performed by the water stopper body 210.
It is advantageous that it can be performed without supporting.

When the faucet body 210 is of a type in which it is divided into a first faucet body 211 and a second faucet body 212 as shown in FIG. 4, the stop cock 60 is assembled. Regardless of the first faucet body 211 attached, the rotary spout 1

However, in the rotary spout 100 of the present embodiment, the cover 30 is divided into the upper cover 31 and the lower cover 32, so that the water supply pipe 40 is divided by the lower cover 32.
This can be done by temporarily fixing the to the deck board 50. That is, even if the faucet body 210 is of the split type shown in FIG.
The fact that the temporary fixing of the faucet is possible means eliminating the problem that the faucet body 210 needs to be supported by putting a hand under the deck plate 50 for a long time,
It is very advantageous in terms of construction.

The merit of dividing the cover 30 into two parts is not only when the rotary water discharge port 100 is newly assembled to the deck plate 50, but also when the respective seal members 22 are replaced,
The same can be said when inspecting the spout body 10, the rotary shaft cylinder 20, and the like. That is, dividing the cover 30 into two means that only the lower cover 32 can be temporarily fixed to the water supply pipe 40, and the workability of assembling, inspecting, and exchanging other members is improved. It also means that it is quite important.

As shown in FIG. 2, for the water supply pipe 40 projecting above the deck plate 50 and the lower cover 32 which is temporarily fixed to the deck plate 50, as shown in FIG. The rotary shaft cylinder 20 in which 10 is integrated and the upper cover 31 assembled to this are assembled. For that purpose, the rotary shaft cylinder 2 in which the spout body 10 is integrated

The screwing degree of the screw portion 31a with respect to the screw portion 32a on the lower cover 32 side is not determined so that the stopper 21 is locked by the upper cover 31 and the lower cover 32 and cannot be rotated. Cover 31
Even if is tightened with respect to the lower cover 32, the rotation of the stopper 21, that is, the rotation shaft cylinder 20 is not hindered.

As a result, the rotary shaft cylinder 20 in which the spout body 10 is integrated has the lower end inserted into the upper end of the water supply pipe 40 and the cover 30 including the upper cover 31 and the lower cover 32. Since it is supposed to cover the periphery while being supported, the water supply pipe 40
It is rotatably supported with respect to the deck board 50. Further, each seal member 22 seals the hot water from the water supply pipe 40 so as not to leak out of the cover 30.

What is important here is that the rotary shaft cylinder 20 is positioned on the water supply pipe 40 and the deck plate 50 by the cover 30 consisting of the upper cover 31 and the lower cover 32, and the cover 30 is separated by the respective sealing members 22. Water pipe 40

That is, by screwing the upper cover 31 to the water supply pipe 40 to which the lower cover 32 is screwed, for example, loosening of the upper cover 31 is prevented between the contact surfaces of the upper cover 31 and the lower cover 32. A large frictional force can be generated, and most of the force applied to the spout body 10 can be applied to the water supply pipe 40 side and not applied to the deck plate 50.

In other words, the upper cover 31 of the cover 30
By making the lower cover 32 act as a double nut for the water supply pipe 40, the fastening force between them and the force from the spout body 10 are transmitted to the faucet body 210 side via the water supply pipe 40. It will be the deck board 5
It is possible to set 0 to a small amount of the force from the spout body 10 in use and the fastening force of the cover 30. Therefore, it is possible to prevent damage to the deck plate 50 to which the rotary spout 100 and the like are attached. On the contrary, in the past, the deck plate 50 was required to have a certain strength or thickness in order to attach the rotary spout 100 of this kind, but this requirement can be relaxed.

Of course, also in the rotary water spout 100 of the second embodiment, as shown in FIG. 3, the length of the rotary shaft cylinder 20 can be made sufficiently short, and therefore the merit by this is also described above. This is similar to the rotary spout 100 of the first embodiment.
