Description

  The present invention relates to a faucet attached to a counter such as a bathroom or a bathroom vanity, and more particularly, to a faucet attachment structure that is rotatably installed in a state in which a water discharge portion that discharges hot water is exposed above the counter.

  As a faucet attached to a counter such as a bathtub or a bathroom vanity, an “embedded faucet” is known in which a spout for discharging hot water is rotatably exposed on the upper part of the counter (for example, (See Patent Document 1). This “embedded faucet” includes a faucet body attached to the lower part of the counter and a water discharge part attached in an exposed state to the upper part of the counter for discharging hot water supplied from the faucet body. The plug body is screwed into the connecting cylinder from the upper part of the counter to fix the connecting cylinder to the counter, the connecting cylinder containing the hot water passage, the mounting bracket rotatably mounted inside the connecting cylinder, and the counter. And the water discharger is fixed to the mounting bracket so as to cover the nut.

  On the other hand, as a faucet installed in a bathtub such as a system bath, a faucet 100 as shown in FIGS. 15A and 15B is known. The faucet 100 includes a water discharger 101, a hot water supply handle 102, a water supply handle 103, and the like that are rotatably installed on the upper edge portion 106 of the bathtub 105 within a predetermined angle range. When the faucet 100 is installed, depending on the layout of the system bus, the “right-hand installation” shown in FIG. 15A or the “left-hand installation” shown in FIG. 15B is performed. ing.

  “Right-hand installation” shown in FIG. 15A is a construction form in the case where there is a wall surface W on the left side of the bathtub 105, so that the water discharge part 101 of the faucet 100 does not come into contact with the wall surface W. The rotation range ZR of the water discharger 101 is set in the upper region of the bathtub 105 away from the wall surface W. “Left-handed installation” shown in FIG. 15B is a construction form in the case where the wall surface W is on the right side of the bathtub 105. Similarly to the “right-handed installation”, the wall surface W is rotated when the water discharger 101 is rotated. The rotation range ZL of the water discharger 101 is set in the upper region of the bathtub 105 away from the wall surface W.

JP 2005-336758 A

  The “embedded faucet” described in Patent Document 1 is superior in that hot water can be discharged in a relatively wide range because the water discharge portion rotates integrally with the mounting bracket, but the rotation range can be changed. Since it cannot do, when it installs in the place where obstacles, such as a wall surface, exist in the rotation range of a water discharging part, when a water discharging part is rotated, it may contact a wall surface etc. Therefore, when this “embedded faucet” is installed in a bathtub such as a system bath, “right-hand installation” shown in FIG. 15A or “left” shown in FIG. It is not possible to cope with “arbitrary installation”.

  On the other hand, the faucet 100 shown in FIG. 15 can perform “left-hand installation” and “right-hand installation” according to the difference in the layout of the unit bath, as described above. Is uniquely determined by the relationship between the stopper inside the connecting tube and the projection of the mounting bracket. Therefore, these two types of installation modes cannot be accommodated with a single set of components, and two types of component sets for "left-handed installation" and "right-handed installation" are available. It's real.

  However, formally, when two types of parts set for “left-handed installation” and “right-handed installation” are set for one kind of faucet 100, the inventory management becomes complicated due to the increase in the number of parts. In addition to inviting, it is easy to induce ordering mistakes, which may cause delays in the construction period due to reordering. In addition, after installation without noticing the incompatibility of the right and left installation mode of the water discharge part at the construction site, when the user operates the water discharge part of the faucet, the user will notice the left and right incompatibility, and it may be necessary to repeat the installation work is there.

  The problem to be solved by the present invention is that both right-handed installation and left-handed installation conditions can be used without changing the components according to the positional relationship with the obstacle present at the installation location of the faucet. An object is to provide a faucet mounting structure that can be used.

The faucet mounting structure of the present invention is a faucet mounting structure that can accommodate both right-handed installation and left-handed installation according to the positional relationship with the obstacle present at the place where the faucet is attached. ,

A rotating shaft that is freely attached, a water discharging portion that discharges the hot water that is fixed to the rotating shaft and passes through the second flow path, and a fixing member that fixes the water discharging portion and the rotating shaft; An operation unit that adjusts hot water flowing in the flow channel and the second flow channel and is attached to the faucet body at a fixed position with respect to the faucet body,
The faucet body has a stopper portion that regulates the rotation range of the rotating shaft,
The rotating shaft has a stopper receiving portion whose rotation is restricted by contacting the stopper portion,
The rotating shaft has an attachment portion to which the water discharge portion is fixed by the fixing member,
Furthermore, the water discharge part has a fixing part to which the rotating shaft is fixed by the fixing member,
The water discharger has a plurality of the fixing parts, and selects one of the plurality of fixing parts to fix the water discharger to the rotating shaft,
Alternatively, the rotating shaft has a plurality of mounting portions in the circumferential direction of the line shaft, and by selecting and using any one of the plurality of mounting portions, the water discharger is fixed to the rotating shaft,
The rotation range of the water discharger relative to the faucet body can be changed.

  With such a configuration, select any one of a plurality of fixed parts provided in the water discharge part or select any one of a plurality of attachment parts provided on the rotating shaft. By doing, the rotation range of the said water discharging part with respect to a faucet main body can be changed. Therefore, it is possible to set the rotation range according to the installation condition of the faucet, that is, the positional relationship with the obstacle present at the place where the faucet is installed. Can also be supported. Also, depending on whether right-handed installation or left-handed installation is performed, there is no need to prepare different members for the faucet body, rotating shaft, and water discharge part. It can correspond to. The faucet body is fixed to the base by reversing the left and right depending on whether it is installed on the right or left hand side, so the position of the stopper also changes. Since the mounting part (or fixed part) is provided, both right-handed installation and left-handed installation can be supported.

Here, the fixing member is a screw, the mounting portion is a mounting hole for fixing the screw, and the fixing portion is a fixing hole for fixing the screw,
The rotating shaft has two mounting holes for left-hand installation and right-hand installation, and the water discharge portion has the fixing hole at a position opposite to the direction of the water discharge port formed in the water discharge portion. Have
It can be set as the structure which carries out screw fixation to the said fixing hole of the said water discharging part with respect to the said attachment hole in the position which the said water discharging port rotated 90 degree | times with respect to the direction which faces the said operation part.

  With such a configuration, as a result of fixing the water discharger from the back side at a position rotated by 90 degrees with respect to the direction in which the water discharge port faces the operation unit, the position of the mounting hole of the rotating shaft is If it is wrong, the screw cannot be fixed to the mounting hole of the rotating shaft, so that an installation error does not occur. That is, it is possible to prevent an installation error in the right-hand installation or the left-hand installation.

  Moreover, the index which shows the position of the attachment hole for the right-hand installation and the left-hand installation can also be provided in the exposed part of the rotating shaft.

  With such a configuration, when fixing the water discharger at a position rotated by 90 degrees with respect to the direction in which the water discharge port faces the operation unit, by visually observing the index provided on the exposed portion of the rotary shaft, Since the positional relationship of the mounting holes can be confirmed, mounting errors can be prevented.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The faucet mounting structure of the present embodiment is an example in which the faucet 10 is installed on the upper edge 31 of the bathtub 30 of the unit bath UB, as shown in FIGS. Either “right-hand installation” (see FIG. 1) or “left-hand installation” (see FIG. 9) can be handled according to the positional relationship between the wall W and the faucet 10 that are present.

  First, “right-hand installation” will be described with reference to FIGS. As shown in FIGS. 1 and 2, the faucet 10 includes a faucet body 12 that is fixed to an upper edge 31 of a bathtub 30 that is a base and a hot water flow path 11 is formed, and a flow of the faucet body 12. A second flow path 13, which is a flow path communicating with the path 11, is formed, a substantially cylindrical rotary shaft 14 rotatably mounted in the faucet body 12, and a second flow path 13 fixed to the rotary shaft 14. The water discharger 15 that discharges the hot water that has passed to the outside, the screws 16 that are fixing members for fixing the water discharger 15 and the rotating shaft 14, the hot water flowing through the flow path 11 and the faucet body 12 And two operation parts 17 and 18 attached to the faucet body 12 at predetermined positions.

  The faucet body 12 has its upper end 12u penetrated upward from below the fixing hole 32 formed in the upper edge portion 31 of the bathtub 30, and the upper end portion 12u of the faucet body 12 from above the upper edge portion 31. The upper edge portion 31 is sandwiched and fixed by the fixing nut 20 screwed to the flange portion 12 and the flange portion 12 f of the faucet body 12. A plurality of sealing materials 21 are interposed between the flange portion 12 f of the faucet body 12 and the upper edge portion 31.

  As shown in FIGS. 2 and 4, a rib-like stopper portion 12 s that restricts the rotation range of the rotary shaft 14 is provided near the bottom of the inner peripheral surface of the faucet body 12. Stopper receiving portions 14 s and 14 t are provided for restricting the rotation of the rotating shaft 14 relative to the faucet body 12 by contacting the stopper portion 12 s. As shown in FIG. 4, stopper receiving portions 14s and 14t are formed by removing a peripheral wall near the lower end of the substantially cylindrical rotating shaft 14 by 90 degrees in the circumferential direction and providing a notch portion 14d. . In addition, since the range of the notch part 14d is not limited to 90 degree | times, it can be set according to an installation place.

  As shown in FIGS. 2 and 3, two recessed mounting holes 14 a and 14 b are formed on the outer periphery of the rotating shaft 14, and the rotating shaft extends from the fixed hole 15 a formed in the base end portion 15 b of the water discharge portion 15. The water discharger 15 is fixed to the rotary shaft 14 by fitting the tip of the screw 16 screwed toward the screw 14 into one of the mounting holes 14a and 14b.

  As shown in FIG. 3, the two mounting holes 14a and 14b are provided at positions separated by 90 degrees along the circumferential direction of the rotating shaft 14, and when the screw 16 is screwed into the fixing hole 15a, the two mounting holes 14a and 14b are provided. By selectively using any one of 14a and 14b and fixing the water discharger 15 to the rotary shaft 14, the rotation range of the water discharger 15 relative to the faucet body 12 can be changed. It is also possible to employ a method in which a plurality of fixing holes are provided in the water discharge portion 15 and any one of the plurality of fixing holes is selected and used to fix the water discharge portion to the rotating shaft.

  The mounting hole 14a provided in the rotating shaft 14 is for the right-hand installation shown in FIG. 1, and the mounting hole 14b is for the left-hand installation shown in FIG. In addition, a fixing hole 15a is formed in the base end portion 15b at a position opposite to the direction of the water discharge port 15c formed in the water discharge portion 15. In the case of “right-handed installation” shown in FIGS. 1 and 2, the attachment hole 15a of the water discharger 15 in a state in which the water discharge 15c is rotated 90 degrees clockwise from the direction facing the operation units 17 and 18 is the water discharge 15c. Is located on the back side of the water discharge portion 15, and the water discharge portion 15 is fixed to the rotating shaft 14 by screws 16 screwed through the attachment holes 15 a on the back side.

  As shown in FIGS. 1 and 2, when the water discharge port 15c of the water discharge unit 15 is at a position rotated 90 degrees clockwise from the direction facing the operation units 17 and 18, the stopper 12s of the faucet body 12 and the rotary shaft 14 The stopper receiving portions 14s and 14t are in the state shown in FIG. That is, the stopper receiving portion 14t of the rotating shaft 14 contacts the stopper 12s of the faucet body 12, and the stopper receiving portion 14s is 90 degrees away from the stopper 12s. Therefore, the rotating shaft 14 is freely rotatable within the range shown in FIG. 4 and the state shown in FIG. 5, and the water discharger 15 fixed to the rotating shaft 14 rotates within the range of the angle 15R shown in FIG. It is free. For this reason, it does not contact the wall surface W when the water discharger 15 is rotated.

  In the step of attaching the faucet 10 to the upper edge portion 31 of the bathtub 30, as shown in FIG. 6, on the upper end surface 14 u of the rotating shaft 14 that is exposed before the water discharge portion 15 is fixed to the rotating shaft 14, An index 14r indicating the position of the mounting hole 14a for right-hand installation (see FIG. 3) and an index 14l indicating the position of the mounting hole 14b for left-hand installation (see FIG. 3) are provided. Accordingly, as shown in FIG. 1, when the water discharger 15 is fixed at a position rotated 90 degrees clockwise relative to the direction in which the water discharge port 15 c faces the operation units 17 and 18, the water discharger 15 is provided at the exposed portion of the rotary shaft 14. Since the positional relationship between the mounting holes 14a and 14b of the rotating shaft 14 can be confirmed by visually checking the indicators 14r and 14l, mounting errors can be prevented.

  When the faucet 10 is attached to the upper edge portion 31 of the bathtub 30 in the form of “right-handed installation”, the stopper of the rotating shaft 14 with respect to the stopper 12s of the faucet body 12 fixed to the upper edge portion 31 by the fixing nut 20. The positional relationship between the receiving portions 14s and 14t must be in the state shown in FIG. However, when it is attempted to fix the water discharger 15 to the rotary shaft 14 while the rotary shaft 14 remains in the state shown in FIG. 7 due to a work mistake or the like, the screw 16 screwed into the fixing hole 15a as shown in FIG. The tip portion comes into contact with the outer peripheral surface of the rotating shaft 14 that is out of the mounting holes 14a and 14b. That is, if the positions of the mounting holes 14a and 14b of the rotating shaft 14 are wrong, the tip of the screw 16 cannot be fixed to any of the mounting holes 14a and 14b of the rotating shaft 14. As described above, the length of the screw 16 is set so that the screw 16 does not fit inside the water discharge portion 15 when the screw 16 cannot be fixed to any of the mounting holes 14a and 14b. It is possible to easily recognize that it is a mistake, and no attachment mistake occurs.

  Next, “left-handed installation” will be described with reference to FIGS. In the case of “left-handed installation” shown in FIGS. 9 and 10, the attachment hole 15 a of the water discharger 15 in a state in which the water discharge 15 c is rotated 90 degrees counterclockwise from the direction facing the operation units 17 and 18 is When 15c is the front, it is located on the back side of the water discharger 15, and the water discharger 15 is fixed to the rotating shaft 14 by screws 16 screwed from the attachment holes 15a on the backside.

  As shown in FIGS. 9 and 10, when the water discharge port 15c of the water discharge unit 15 is at a position rotated 90 degrees counterclockwise from the direction facing the operation units 17 and 18, the stopper 12s of the faucet body 12 and the rotation shaft The 14 stopper receiving portions 14s and 14t are in the state shown in FIG. That is, the stopper receiving portion 14s of the rotating shaft 14 contacts the stopper 12s of the faucet body 12, and the stopper receiving portion 14t is 90 degrees away from the stopper 12s. Therefore, the rotating shaft 14 is rotatable within the range shown in FIG. 12 and the state shown in FIG. 13, and the water discharger 15 fixed to the rotating shaft 14 rotates within the range of the angle 15L shown in FIG. It is free. For this reason, it does not contact the wall surface W when the water discharger 15 is rotated.

  Further, as shown in FIG. 14, a mounting hole 14 a (see FIG. 3) for right-hand installation is formed on the upper end surface 14 u of the rotating shaft 14 that is exposed before the water discharger 15 is fixed to the rotating shaft 14. An index 14r indicating the position and an index 141 indicating the position of the left-hand installation hole 14b (see FIG. 11) are provided. Therefore, as shown in FIG. 9, when the water discharger 15 is fixed at a position rotated 90 degrees counterclockwise with respect to the direction in which the water discharge port 15 c faces the operation units 17 and 18, the water discharger 15 is provided on the exposed portion of the rotary shaft 14. Since the positional relationship between the mounting holes 14a and 14b of the rotating shaft 14 can be confirmed by visually checking the indicators 14r and 14l, mounting errors can be prevented.

  In addition, when the faucet 10 is attached to the upper edge 31 of the bathtub 30 in the form of “left-handed installation”, when the positions of the attachment holes 14a and 14b of the rotary shaft 14 are incorrect due to a work mistake or the like, FIG. As shown, since the tip of the screw 16 cannot be fixed to any of the mounting holes 14a and 14b of the rotary shaft 14, no mounting error occurs.

  As described above, by selecting any one of the two mounting holes 14a and 14b provided on the rotating shaft 14 of the faucet 10 and inserting the tip of the screw 16, the water discharger for the faucet body 12 is inserted. Fifteen rotation ranges can be changed. Therefore, the rotation range can be set according to the positional relationship with the obstacle (for example, the wall surface W) present in the place (for example, the unit bus UB) where the faucet 10 is installed. Both “left-handed installation” installation conditions are available.

  Therefore, it is not necessary to prepare different members for the faucet body 12, the rotating shaft 14, and the water discharger 15 depending on whether "right-handed installation" or "left-handed installation" is performed. Both “arbitrary installation” and “right-hand installation” can be handled. The faucet body 12 is fixed to the base (upper edge portion 31) by reversing the left and right depending on whether “right-hand installation” or “left-hand installation” is selected, so that the position of the stopper 12s also changes. However, since the two mounting holes 14a and 14b are provided in the rotating shaft 14 accordingly, both “right-handed installation” and “left-handed installation” can be handled.

  In addition, by adopting a method in which the water discharge part 15 is fixed to the rotary shaft 14 from the back side at a position where the water discharge port 15c of the water discharge part 15 is rotated 90 degrees with respect to the direction facing the operation parts 17 and 18, If the positions of the mounting holes 14a and 14b of the rotating shaft 14 are wrong, the screws 16 cannot be fixed to the mounting holes 14a and 14b of the rotating shaft 14, so that mounting errors do not occur. For this reason, it is possible to prevent an installation error of “right-hand installation” or “left-hand installation”.

  Furthermore, the upper end surface 14u, which is the exposed portion of the rotating shaft 14, is provided with indicators 14r and 14l indicating the positions of the mounting holes 14a and 14b for “left-handed installation” and “right-handed installation”, thereby discharging water. 15 is fixed at a position rotated by 90 degrees with respect to the direction in which the water discharge port 15c faces the operating portions 17 and 18, by visually observing the indicators 14r and 14l provided on the exposed portions of the rotary shaft 14, Since the positional relationship between the mounting holes 14a and 14b can be confirmed, mounting errors can be prevented.

  In the above-described embodiment, the faucet 10 in which the faucet body 12 is embedded in the lower portion of the upper edge portion 31 of the bathtub 30 has been described. However, the present invention is not limited to this. Needless to say, it can be realized even if it is fixed to the upper surface of the upper edge portion 31.

  Furthermore, although the above-mentioned embodiment demonstrated the case where each of the concave-shaped attachment holes 14a and 14b provided in the rotating shaft 14 was made into one attachment part, it is not limited to this. For example, a plurality of rotating shafts are provided with mounting portions made of a pair of concave portions, and a water discharging portion is provided with one fixing portion made of a pair of holes, and at each fixed position, the water discharging portion and the rotating shaft are provided by two screws. It is good also as a structure which fixes.

  The faucet attachment structure of the present invention can be widely used as a construction technique for faucets that are attached to counters such as bathrooms and bathroom vanities in general housing or accommodation facilities such as hotels and inns.
