  The faucet main body 2 is formed in a horizontally elongated substantially cylindrical shape. As shown in FIG. 2, the faucet main body 2 has a round hole-shaped hot water supply port 3 on its bottom surface for receiving hot water from a hot water supply source (not shown) and a round hole for receiving water from a hot water supply source (not shown). And a water supply port 4 in a hole shape. The hot water supply port 3 is connected to a connection port 8A on the upper side in the drawing of the hot water side joint pipe 8 having an eccentric shape bent in a crank shape. Specifically, the connection port 8A on the upper side of the hot water side joint pipe 8 is screwed to the cap nut 3A attached to the hot water supply port 3, so that the connection port 8A is flow-connected to the hot water supply port 3. .

  The hot water side joint pipe 8 is a round hole-shaped hot water pipe formed such that a pipe portion 8C which is bent in a crank shape and extends to the lower connection port 8B in the drawing penetrates a corresponding position on the top plate B. It is inserted into the side insertion opening B1 from above and fixed to the top plate B (see FIGS. 4 and 5). In the hot water side joint pipe 8, a hot water supply pipe extending from a hot water supply source (not shown) is connected to a connection port 8 </ b> B of the top plate B which has passed through the hot water side insertion port B <b> 1 downward. . Each connection port 8A, 8B of the hot water side joint pipe 8 is directed straight in the vertical direction (opposing direction L) where the faucet main body 2 and the top plate B oppose each other.

  Here, the hot-water-side insertion port B1 of the top plate B into which the pipe portion 8C of the hot-water-side joint pipe 8 is inserted is a hot-water supply port which is a connection port of a hot-water supply pipe extending from a hot-water supply source (not shown). And a coaxial line. Therefore, the hot water side insertion port B1 has the same configuration as the hot water supply port (not shown) on the top plate B side.

  Specifically, as shown in FIG. 3, the hot-water-side joint pipe 8 has a pipe portion 8C extending to a connection port 8B on the lower side in the drawing, and a lower portion of the pipe body portion 8C formed on a resin body cover 7 covering the faucet body 2. It is provided so as to extend downward from the elongated hole 11A as it is passed through the elongated hole 11A formed in the seat plate 11 of the resin-made guide cover 10 mounted from the front. More specifically, as shown in FIG. 6, the hot-water-side joint pipe 8 has a flange-shaped seat portion 8 </ b> E formed at an intermediate portion of the pipe portion 8 </ b> C around the elongated hole 11 </ b> A of the guide cover 10. The pipe section 8C is passed through the elongated hole 11A as a state in which the pipe section 8C is in contact with the seat plate 11 from above. Here, the guide cover 10 corresponds to the “guide fixed body” of the present invention.

  As shown in FIG. 4 and FIG. 5, the hot water side joint pipe 8 having the above configuration has a pipe portion 8 </ b> C extending downward from the long hole 11 </ b> A into the hot water side insertion port B <b> 1 of the top plate B from above. By being inserted, the movement in the insertion direction is restricted at a position where the seat plate 11 of the guide cover 10 abuts the installation surface Ba on the top plate B. In the above-mentioned state, the hot-water-side joint pipe 8 is set in a state where the seat portion 8E is sandwiched between the seat plate 11 of the guide cover 10 and the top plate B.

  Therefore, next, a fastening nut (not shown) is connected to the male screw 8D formed on the outer peripheral wall of the conduit 8C from the end of the molten metal-side joint pipe 8 which penetrates downward through the molten metal-side insertion port B1. After screwing, the fastening nut is tightened to a position where it is fastened to the back surface of the top plate B. As a result, the top plate B and the seat plate 11 of the guide cover 10 are fastened in a state where the seat plate 8E and the seat plate 11 of the guide cover 10 are integrally pressed between the seat portion 8E of the hot water side joint pipe 8 and the fastening nut (not shown). As described above, the pipe portion 8C extending downward in the drawing of the hot water side joint pipe 8 is integrally assembled to the top plate B in a state of being inserted into the hot water side insertion port B1 of the top plate B from above.

  As shown in FIG. 2, similarly to the above, the water supply port 4 is connected to a connection port 9 </ b> A on the upper side in the drawing of the water side joint pipe 9 having an eccentric shape bent in a crank shape. Specifically, the connection port 9A on the upper side of the water-side joint pipe 9 is screwed to the cap nut 4A attached to the water supply port 4, whereby the connection port 9A is connected to the water supply port 4 in a flow path. .

  The water-side joint pipe 9 is a round hole-shaped water pipe formed by passing through a pipe portion 9C which is bent in a crank shape and extends to a lower connection port 9B in the drawing at a corresponding position on the top plate B. It is inserted into the side insertion port B2 from above and fixed to the top plate B (see FIGS. 4 and 5). In the water-side joint pipe 9, a water supply pipe extending from a water supply source (not shown) is connected to the connection port 9B of the top plate B, which is located below the water-side insertion port B2. . The connection ports 9A and 9B of the water-side joint pipe 9 are directed straight in the vertical direction (opposing direction L) in which the faucet main body 2 and the top plate B oppose each other.

  Here, the water-side insertion port B2 of the top plate B into which the pipe section 9C of the water-side joint pipe 9 is inserted is a water supply port which is a connection port of a water supply pipe extending from a water supply source (not shown). Water supply port ”) and a position on the same coaxial line. Therefore, the water-side insertion port B2 has a configuration that has the same meaning as the water supply port (not shown) on the top plate B side.

  More specifically, as shown in FIG. 3, the water-side joint pipe 9 has a pipe portion 9 </ b> C extending to a lower connection port 9 </ b> B on the seat plate 11 of the resin-made guide cover 10. The elongated hole 11A is provided so as to extend downward from the elongated hole 11A. More specifically, as shown in FIG. 6, the water-side joint pipe 9 has a flange-shaped seat 9E formed at an intermediate portion of the pipe section 9C so as to surround the elongated hole 11A of the guide cover 10. The pipe 9C is passed through the elongated hole 11A as a state in which the pipe 9C is in contact with the seat plate 11 from above.

  As shown in FIGS. 4 and 5, the water-side joint pipe 9 having the above-described configuration has a pipe portion 9 </ b> C extending downward from the long hole 11 </ b> A into the water-side insertion port B <b> 2 of the top plate B from above. By being inserted, the movement in the insertion direction is restricted at a position where the seat plate 11 of the guide cover 10 abuts the installation surface Ba on the top plate B. In the above state, the water-side joint pipe 9 is set in a state in which the seat 9E is sandwiched between the seat plate 11 of the guide cover 10 and the top plate B.

  Therefore, next, a fastening nut (not shown) is connected to the external thread 9D formed on the outer peripheral wall of the pipe section 9C from the end of the water-side joint pipe 9 which penetrates downward through the water-side insertion port B2. After screwing, the fastening nut is tightened to a position where it is fastened to the back surface of the top plate B. As a result, the top plate B and the seat plate 11 of the guide cover 10 are fastened in a state where the seat plate 9E and the seat plate 11 of the guide cover 10 are integrally pressed between the seat portion 9E of the water-side joint pipe 9 and a fastening nut (not shown). As described above, the pipe section 9C extending downward in the drawing of the water-side joint pipe 9 is inserted into the water-side insertion port B2 of the top plate B from above, and is integrally assembled to the top plate B.

  Then, the guide cover 10 is installed on the top plate B by the above-described assembly by the pipe section 8C of the hot-side joint pipe 8 and the pipe section 9C of the water-side joint pipe 9 passed through the long hole 11A. The movement in the front-rear direction with respect to the surface Ba is fixed in a restricted state. Thereby, the body cover 7 covering the faucet body 2 to which the guide cover 10 is attached is similarly fixed, and the faucet body 2 is fixed at a fixed position. As shown in FIG. 2, the main body cover 7 is formed in a horizontally elongated box shape that covers substantially the entire area of the faucet main body 2 except for a portion connected to other members such as the hot water supply port 3 and the water supply port 4. The main body cover 7 is assembled so as to be integrally fixed to the faucet main body 2.

  Further, the main body cover 7 is formed in a shape having a projecting plate portion 7A projecting like a hanging plate from the entire region of the front edge portion in the width direction W. The guide cover 10 is formed in a horizontally elongated box shape with an upward opening that matches the main body cover 7 by being fitted into the main body cover 7 from below. Specifically, the guide cover 10 is formed in an oblong box shape having an upward opening and having a horizontally long plate-shaped seat plate 11 and a surrounding portion 12 that rises in a rectangular cylindrical shape from the periphery of the seat plate 11.

  A long hole 11A is formed in the seat plate 11 so as to extend straight in the width direction W. The long hole 11A has a hole width in the front-rear direction slightly larger than the outer diameter of the conduit portion 8C of the hot-side joint tube 8 and the outer diameter of the conduit portion 9C of the water-side joint tube 9, but is formed therein. It is smaller than the outer diameter of the seat portions 8E and 9E that protrude like a flange. The guide cover 10 passes through the conduit 8C of the hot-side joint pipe 8 and the conduit 9C of the water-side joint pipe 9 into the elongated hole 11A, and opens the upper opening of the guide cover 7A of the main body cover 7. By setting it so as to be pushed onto the bottom surface on the back side of the main body, the main body cover 7 is assembled into a substantially box-shaped shape having a horizontally long body with a sense of unity (see FIG. 3).

  Specifically, as shown in FIG. 2, the guide cover 10 is provided at four corners of an edge on the opening side of the surrounding portion 12, and at four corresponding corners on the bottom surface of the main body cover 7. A protruding pin-shaped restricting engagement portion 13 that is fitted by being pushed into the hole 7B from below is formed. Therefore, the guide cover 10 is assembled to the main body cover 7 by assembling the guide cover 10 so that each of the restriction engagement portions 13 is fitted into each of the corresponding engagement holes 7 </ b> B. (See FIG. 3). With the above assembly, a part of the conduits of the hot water side joint pipe 8 and the water side joint pipe 9 extending downward from the faucet main body 2 is entirely covered by the surrounding portion 12 of the guide cover 10 so as to be invisible from the outside. And it looks good.

  Then, as a result of the assembling, the pipe section 8C of the hot-side joint pipe 8 and the pipe section 9C of the water-side joint pipe 9 passed through the elongated holes 11A of the guide cover 10 are rotated by the restriction of the elongated holes 11A, respectively. It is kept stopped. As shown in FIG. 5, the elongated hole 11A of the guide cover 10 is formed so as to hold the hot-side joint pipe 8 and the water-side joint pipe 9 in a direction of eccentricity straight in the width direction W, respectively. That is, the elongated hole 11A of the guide cover 10 is formed to extend straight in the width direction W so as to pass through a position vertically facing the hot water supply port 3 and the water supply port 4 of the faucet main body 2.

  Due to the position regulation by the elongated hole 11A of the guide cover 10, the hot water side joint pipe 8 is different from the faucet main body 2 by the hot water side difference between the upper connection port 8A connected to the hot water supply port 3 and the top plate B. The lower connection port 8B passed through the inlet B1 is held in a rotational direction that is eccentric straight in the width direction W. The water-side joint pipe 9 is also connected to the faucet main body 2 by an upper connection port 9A connected to the water supply port 4 and a lower connection port passed through the water-side insertion port B2 of the top plate B. The mouth 9B and the opening 9B are held in a rotational direction that is eccentric straight in the width direction W. Thereby, all four of the connection ports 8A and 8B of the hot-side joint pipe 8 and the four connection ports 9A and 9B of the water-side joint pipe 9 are arranged on the same plane (vertical plane) extending in the width direction W. It is kept in a state.

  Therefore, compared to a configuration in which the hot water side joint pipe 8 and the water side joint pipe 9 are assembled at an angle in a shape of a letter C, the installation space in the front-rear direction of the entire mixing faucet 1 is reduced. Can be suppressed. Further, the guide cover 10 surrounding the hot water side joint pipe 8 and the water side joint pipe 9 can also be formed in a shape that is not bulky in the front-rear width.

  In the mixing faucet 1 described above, the hot-side joint pipe 8 and the water-side joint pipe 9 are eccentric to the right from the insertion positions of the top plate B with respect to the hot-side insertion port B1 and the water-side insertion port B2, respectively. It is set on the top plate B in the rotated state (second direction state P2). In the present embodiment, the hot-side joint pipe 8 and the water-side joint pipe 9 are configured to have the same shape and size. By the installation in the rotation direction, the mixing faucet 1 is installed on the top plate B in a state of being widely separated from the left side wall S of the bathtub to the right by a width W2. Thereby, the mixing faucet 1 has a wide operation space between the temperature control handle 20 attached to the left side thereof and the left side wall S, and makes the operation of the temperature control handle 20 cramped. It can be done comfortably without.

  However, in the mixing faucet 1, as shown in FIG. 7, the hot water side joint pipe 8 is in a rotational direction (first direction) eccentric to the left from the insertion position of the top plate B into the hot side insertion port B1. As the state P1), it can be installed on the top plate B. Specifically, first, the hot metal side joint pipe 8 is set to the first orientation state P1 as described above. Next, as shown in FIG. 8, the water-side joint pipe 9 having a shape matching the eccentricity of the water supply port 4 of the faucet body 2 and the water-side insertion port B2 of the top plate B at that time is connected to the faucet body 2. Set to. Thereby, as shown in FIG. 9, the hot-side joint pipe 8 and the water-side joint pipe 9 in the first orientation state P1 are connected to the hot-side socket B1 and the water-side socket B2 of the top plate B. And can be assembled on the top plate B. Here, the hot metal side joint pipe 8 corresponds to “one of a pair of joint pipes” of the present invention. Further, the water-side joint pipe 9 corresponds to “the other of the pair of joint pipes” of the present invention.

  In the present embodiment, as described above with reference to FIG. 5, the hot water side joint pipe 8 and the water side joint pipe 9 are configured to have the same shape and size as each other. Therefore, as shown in FIGS. 8 and 9, the water-side joint pipe 9 applied when the hot-side joint pipe 8 is in the first orientation state P1 is the same as the water-side joint pipe 9 described above. It will be set in the opposite direction. Due to the installation in the rotation direction, the mixing faucet 1 is installed on the top plate B in a state of being narrowly separated from the left side wall S of the bathtub to the right by a width W1 as shown in FIG. In this case, the operation space of the mixing faucet 1 between the temperature control handle 20 attached to the left side thereof and the left side wall S is narrowed. It becomes difficult.

  Therefore, in this case, as shown in FIG. 10, contrary to the previous case, first, the hot metal side joint pipe 8 is rotated rightward eccentrically from the insertion position of the top plate B into the hot metal side insertion port B1. Set to the orientation state (second orientation state P2). Next, as shown in FIG. 11, a water-side joint pipe 9 having the shape corresponding to the eccentric size of the water supply port 4 of the faucet main body 2 and the water-side insertion port B2 of the top plate B at that time (the same as the previous one) ) Is set on the faucet body 2. Thereby, as shown in FIG. 5, the hot-side joint pipe 8 and the water-side joint pipe 9 in the second orientation state P2 are connected to the hot-side socket B1 and the water-side socket B2 of the top plate B. And can be assembled to the top plate B.

  The water-side joint pipe 9 applied when the hot-water joint pipe 8 is in the second orientation state P2 is, as described above, the water supply port 4 of the faucet main body 2 and the water of the top plate B at that time. One having a shape that matches the eccentric dimension of the side insertion opening B2 is appropriately selectively applied. Therefore, as shown in FIG. 12, the water-side joint pipes 9, 9 having a corresponding shape according to the eccentric dimensions of the water supply port 4 and the water-side insertion port B2 at the place where the mixing faucet 1 is installed. ', 9 "may be appropriately selected and set.

  As described above, the switching of the assembling position of the mixing faucet 1 in the width direction W is performed by changing the direction of the eccentric direction of the hot-water joint pipe 8 left and right with the hot-water joint pipe 8 as a base axis as described above. The joint pipes 9, 9 ', 9 "may be replaced with a pipe having a matching shape at that time. However, the direction of the eccentric direction of the water-side joint pipe 9 is changed left and right with the water-side joint pipe 9 as a base axis, and The side joint pipe (8) may be replaced with a pipe having the same shape at that time.The mounting position of the mixing faucet 1 in the width direction W depends on the restriction on the installation location of the mixing faucet 1 and the purpose of use. Thus, whether to install in the first orientation state P1 or in the second orientation state P2 may be freely selected at the time of assembly work.

  In summary, the mixing faucet 1 according to the first embodiment has the following configuration. That is, the water supply ports (3, B1) and the water supply port (3) between the faucet main body (2) in which the operation handle (20) is attached to the side in the width direction (W) and the installation surface (Ba). 4, B2) is a mixing faucet (1) having a pair of joint pipes (8, 9) for individually connecting flow paths. A pair of joint pipes (8, 9) direct connection ports (8A, 8B, 9A, 9B) to the faucet body (2) and the installation surface (Ba) in opposite directions (L), respectively, and connect these. The mouths (8A, 8B, 9A, 9B) have a crank shape that is arranged eccentrically to each other so that all four are arranged on the same plane in the width direction (W).

  The mixing faucet (1) further connects one (8) of the pair of joint pipes (8, 9) to the corresponding connecting port (8A) with respect to the faucet body (2) or the installation surface (Ba). ) To a first orientation state (P1) in which the eccentric direction of the crank faces one side in the width direction (W) and a second orientation state (P2) in which the eccentric direction faces the other side in the width direction (W). It has a swing structure that can be switched by rotation, and the other (9) of the pair of joint pipes (8, 9) is either the first (8) switched first orientation state (P1) or the second (9). The eccentric shape corresponding to the orientation state (P2) is selectively applied appropriately, and the mounting position of the faucet main body (2) with respect to the installation surface (Ba) is changed to the first orientation state (P1). ) And the second orientation state (P2).

  According to the above configuration, one (8) of the pair of joint pipes (8, 9) is switched to the first orientation state (P1) or the second orientation state (P2), and the other (9) is switched to the first orientation state (P2). With a simple configuration having an eccentric shape corresponding to the orientation state, the width of the mixing faucet (1) provided with the operation handle (20) on the side in the width direction (W) with respect to the installation surface (Ba) is provided. The mounting position in the direction (W) can be adjusted.

  Further, the mixing faucet (1) further linearly extends in the width direction (W) the pipe section (8C, 9C) on the side connected to the installation surface (Ba) of the pair of joint pipes (8, 9). And a guide fixing body (10) sandwiched between a pair of joint pipes (8, 9) and an installation surface (Ba) in a state of being passed through a long hole (11A) extending to the bottom. The guide fixing body (10) has a regulating engagement portion (13) that regulates movement of the faucet body (2) with respect to the installation surface (Ba) by engagement with the faucet body (2). According to the above configuration, the guide fixing body (10) fixed in a state of being positioned by the pipe sections (8C, 9C) on the side connected to the installation surface (Ba) of the pair of joint pipes (8, 9).
