Description

The present invention relates to a single water faucet, and more specifically, a structure for attaching a single water faucet such as a horizontal water faucet or a water faucet to the front end of a water supply pipe exposed from a hole in a faucet mounting surface such as a wall surface. About.
In this specification, the “faucet mounting surface” includes the upper surface of a horizontal plate such as a counter in addition to the wall surface.

  In general, a single water faucet has a single valve portion, and water discharge, water stoppage, and flow rate adjustment are performed by opening and closing the valve portion by operating a handle.

To attach the single faucet to the wall surface, wrap a seal tape around the male threaded water inlet formed at the rear of the faucet body, and then connect the male threaded water inlet to the front end of the water supply pipe. It is carried out by screwing into the female thread part of the pipe joint constituting.
The above screwing operation is performed when the distance between the outer annular decorative flange portion formed near the base end portion of the water inlet in the faucet body and the wall surface is reduced to a predetermined distance. However, if the seal tape is unscrewed as much as possible, the sealing performance will be impaired and water leakage will occur.

  However, the above-described mounting operation requires skilled techniques / experience regarding grasping the number of windings / winding of the sealing tape and the distance between the decorative flange and the wall surface. When a construction beginner installs a single faucet, there is a high possibility that construction will be insufficient and water leakage will occur, or the direction of the handle will not come to the proper position, and eventually it will be necessary to ask a specialist contractor. There was a problem.

By the way, when the mixing faucet was attached to the wall surface, there was a construction problem similar to the above. As a means for solving this problem, the present inventor used the following for the mixing faucet connection. A pipe joint was proposed (see Patent Document 1 below).
That is, this mixed water faucet connection pipe joint is rotatable to the first tubular joint member from the front end side of a horizontal tubular first pipe joint member having a male threaded pipe connection port on the rear end side. And a rotating cylinder part fitted in such a manner that it can be moved back and forth, a hollow arm part extending in the radial direction from the front end of the rotating cylinder part, and a mixing faucet connection port provided in a forward projecting manner at the tip of the arm part And a second pipe joint member. On the inner peripheral surface of the rotating tube portion of the second pipe joint member, one engaging convex portion or a plurality of engaging convex portions are formed at intervals in the circumferential direction. An annular groove that accommodates the engaging convex portion is formed on the outer peripheral surface of the first pipe joint member, and the rotating cylindrical portion is moved rearward on the rear side surface of the annular groove to engage with the engaging convex portion. One or more engaging recesses to be matched are formed at intervals in the circumferential direction.

According to the above-described pipe joint, first, the rotating cylinder part of the second pipe joint member is moved rearward, and the engagement convex part is engaged with the engagement concave part of the first pipe joint member. By this operation, the rotation cylinder part of the second pipe joint member is made unrotatable with respect to the first pipe joint member. Moreover, a sealing tape is wound around the male screw of the pipe connection port of the first pipe joint member. Then, by holding the second pipe joint member by hand in this state and turning it in the required direction, the male thread at the pipe connection port of the first pipe joint member is screwed into the female thread at each front end of the hot water supply pipe and the water supply pipe. . After the screwing operation is completed, when the rotating cylinder portion is moved forward, the engaging convex portion is disengaged from the engaging concave portion and is positioned in the annular groove, and the rotating cylindrical portion rotates with respect to the first pipe joint member. It becomes possible. Then, the rotation tube part is rotated by a required angle so that the mixing faucet connection port is at a position suitable for connecting the mixing faucet, and the mixing faucet connection port is connected to the hot water of the mixing faucet body or Connect to the water inlet.
In this way, if the above-mentioned mixed water tap connection pipe joint is used, even a so-called beginner of construction can connect the mixed water tap to the hot water supply pipe and the water supply pipe without requiring skill and experience. This can be done very easily and reliably.

However, in the case of the mixed water faucet, there are two connection points on the left and right of the hot water supply pipe and the water supply pipe. Therefore, even if the above pipe joint is used, the rotating cylinder portion of each pipe joint rotates after the construction, causing a problem. However, if the structure of this pipe joint is applied as it is to the mounting structure of a single water faucet, there is a problem because the rotating cylinder part rotates freely after construction.
JP 2006-118118 A

  An object of the present invention is to provide a single water faucet that can be easily and reliably attached to a wall surface or the like even for a beginner of construction.

The lock member (4) does not have a first annular step on its inner peripheral surface, and a serration (46) is formed in the rear portion of the second annular step (43) on the inner peripheral surface. This serration (46) is obtained when the lock member (4) is at the rearward movement end, that is, in the lock position, the serration (31) of the male screw member (3) and the serration (215) of the water introduction port (21). On the other hand, when the lock member (4) is in the forward movement end, that is, in the unlocked position, it engages only with the serration (215) of the water inlet (21). That is, in this embodiment, the serration (46) of the locking member (4) is shared by the engagement with the two members (3) (21).
Therefore, according to the single water faucet (1B) of this embodiment, since the structure of the lock member (4) is simplified, the cost can be reduced.
Further, the first tubular member (21b) has an annular outer convex portion (219) at a rear portion of the annular step (217) on the outer peripheral surface thereof, and the annular outer convex portion (219) and a lock A spring (5) is interposed between the second annular step (44) of the member (4).
