The faucet device 100 shown in FIG. 2 is a type in which the lever handle 10 is on the upper surface of the faucet body 20, and is configured such that water or hot water comes out from the tip of the spout 35 by operating the lever handle 10. Yes.

  The faucet device 100 is provided at a place where it is installed (for example, the top plate S around the sink) with a screw and a flange, and is provided so as to be rotatable in the left-right direction with respect to the faucet body 20. And a rotating body 30. The rotating body 30 includes a spout holder 32 provided so as to cover the faucet body 20 and a spout 35 held by the spout holder 32. The faucet device 100 is a type called a drawer type, and the spout 35 can be pulled out from the spout holder 32. In the present application, “left-right direction” means a direction in which the spout 35 rotates, “front” means a direction in which the spout 35 extends, and “rearward” means a direction in which the spout 35 extends. Means the opposite direction.

  As shown in FIG. 2, a rotation restricting attachment (rotation restricting portion) 50 is mounted on the top plate S below the faucet device 100. The attachment 50 is for restricting the rotation range of the rotating body 30. The attachment 50 may be regarded as a part of the configuration of the faucet device 100, or may be regarded as a configuration separate from the faucet device 100.

  The faucet body 20 has an outer surface 20F extending upward from the top plate S (see FIG. 3), and the base member 52 of the attachment 50 is fixed to the outer surface 20F (see FIG. 2). On the other hand, the spout holder 32 has an outer surface 32F that rotates together with the spout 35 (see FIG. 3), and the regulating member 54 of the attachment 50 is fixed to the outer surface 32F in the vicinity of the boundary with the outer surface 20F of the faucet body 20. (See FIG. 2). The regulating member 54 rotates as the spout holder 32 rotates. FIG. 4 is a view of the spout holder 32 as viewed obliquely from below.

  As shown in FIG. 5, the attachment 50 includes an annular base member 52 and an annular regulating member 54 placed on the upper surface 52 </ b> F of the base member 52. The positions of the upper surface 52F of the base member 52 and the bottom surface 54F of the regulating member 54 that abuts on the base member 52 coincide with the boundary between the outer surface 20F and the outer surface 32F (see FIG. 3). Both the base member 52 and the regulating member 54 are composed of two separable parts. That is, the base member 52 includes a front base member 52a and a rear base member 52b. The restriction member 54 includes a front restriction member 54a and a rear restriction member 54b.

  Examples of the material of the base member 52 and the regulating member 54 include metals and resins, and resins are preferable from the viewpoint of cost. Of the resins, a thermoplastic resin is preferable from the viewpoint of processability, and specific examples thereof include ABS, POM, and PP. From the viewpoint of the appearance of the base member 52 and the regulating member 54, it is preferable to subject the surface to plating. Further, from the viewpoint of cleanability, it is preferable to provide R in the vicinity of the outer surface 32F of the spout holder 32 on the outer surface of the regulating member 54 to improve the wiping property.

  FIG. 6 shows a state in which the rear regulating member 54b is removed from a plurality of parts constituting the attachment 50. FIG. As shown in FIG. 6, the rear base member 52b has a semicircular shape, and the flat upper surface forms part of the upper surface 52F. A plurality of openings H are provided along the radial direction on the upper surface of the rear regulating member 54b. The openings H are preferably provided at intervals of a central angle of 5 to 20 ° when the base member 52 is regarded as a circle. If the central angle is 5 ° or more, there is an advantage that the meat between the two adjacent openings H can be sufficiently secured, and sufficient strength can be obtained and the manufacturing is easy. On the other hand, if the center angle is 20 ° or less, a sufficient degree of freedom in adjusting the rotation range can be secured.

  In the present embodiment, seven openings H are provided so as to be arranged on one side of the rear base member 52b, and the other seven openings H are provided so as to be arranged on the other side. Note that the number of openings H and the positions to be formed are not limited to the embodiment shown in FIG.

  The opening H is configured so that a pin (extending member) P can be attached thereto. When one side of the pin P is inserted into the opening H, the other side protrudes upward as shown in FIG. The portion protruding above the pin P directly contacts the contact surface F (see FIG. 12) of the rear regulating member 54b, so that the rotation range of the rotating body 30 is restricted. As a material of the pin P, a metal is preferable from the viewpoint of strength, and stainless steel (for example, SUS304) is more preferable from the viewpoint of preventing rust. In addition, when resin is employ | adopted as a material of the pin P, it is preferable to make the width | variety of the pin P wide from an intensity | strength surface. For example, a mode in which a plurality of pins P are connected in the horizontal direction may be provided, and an opening corresponding to this may be provided in the rear base member 52b. Here, the mode in which the pin P directly contacts the contact surface F of the rear regulating member 54b is illustrated, but the mode in which the rotation is regulated by the pin P indirectly contacting the contact surface F through another member. It is good.

  FIG. 7 is a perspective view of the base member 52 with the front regulating member 54a removed from the state of FIG. As shown in FIG. 7, the front base member 52 a and the rear base member 52 b are fixed to each other by screws 55. At both ends of the rear base member 52b, plate-like extending portions 52c for mounting screws 55 extend in the direction of the front base member 52a (see FIG. 8). The front base member 52a has a surface 52d in which a screw hole for the screw 55 is formed at a height corresponding to the lower surface of the extending portion 52c. In addition, the surface 52d is provided at a position lower than the upper surface 52F of the base member 52 so as not to prevent the regulating member 54 from sliding.

  FIG. 9 shows the bottom surface of the base member 52. As shown in FIG. 9, both ends of the front base member 52a and the rear base member 52b are fixed with claws. The front base member 52a has an inclined surface 52e provided at an acute angle from the outer periphery toward the inner periphery. On the other hand, the rear base member 52b has an inclined surface 52f provided at an acute angle from the inner periphery toward the outer periphery. The inclined surface 52e and the inclined surface 52f are brought into contact with each other from the state in which the front base member 52a and the rear base member 52b are separated from each other, and a force is applied in a direction in which both approach the front base member 52a and the rear base member 52b. Both can be integrated. At this time, when the inclined surfaces 52e and 52f slide relative to each other, both ends of the front base member 52a are opened, and on the other hand, both ends of the rear base member 52b enter inside, and then both are fitted.

  In addition, although the front base member 52a and the back base member 52b were fixed with the nail | claw while fixing with the screw 55 here, for example, you may fix both only with a screw | thread. In this case, from the viewpoint of workability, it is preferable that the two left and right screws 58 are tightened from the front to the rear (see FIG. 10).

  It is preferable to sufficiently increase the friction between the inner surface of the base member 52 and the outer surface 20F so that the base member 52 does not move relative to the outer surface 20F of the faucet body 20. In the present embodiment, an anti-slip member 56 is disposed between the inner surface and the outer surface 20F. Specific examples of the anti-slip member 56 include rubber and elastomer, and rubber is preferable from the viewpoint of a high anti-slip effect. Of the types of rubber, silicone rubber, nitrile rubber, and ethylene propylene rubber are preferred because they have good compression set resistance. From the viewpoint of improving the assemblability of the base member 52, a plurality of ribs 52g extending in the vertical direction are provided on the inner surface of the base member 52 at predetermined intervals in the circumferential direction (see FIGS. 8 and 9). Since the rib 52g partially crushes the non-slip member 56, the base member 52 can be nail-fixed with a small force.

  In addition, although the aspect which uses the non-slip | skid member 56 for fixing the base member 52 with respect to the faucet main body 20 was illustrated here, in addition to this, various things, such as adhesion | attachment, screwing, a fitting, a double-sided tape, etc. Fixing means can be used. For example, even if the convex portion is provided on the outer surface 20F of the faucet body 20, the corresponding concave portion is provided on the inner surface of the base member 52, and the base member 52 is fixed to the faucet body 20 by fitting them. Good. Conversely, a recess may be provided on the outer surface 20F of the faucet body 20, and a corresponding protrusion may be provided on the inner surface of the base member 52.

  As described above, the base member 52 is fixed to the outer surface 20F by claw-fixing the two members 52a and 52b, while the restricting member 54 has a protrusion 54c that the front restricting member 54a has in the water of the spout holder 32. The spout holder 32 is fixed by fitting into one of the punched holes 32a (see FIGS. 3 and 4). A faucet device (drawer-type faucet device) that can pull out a spout generally has a drain hole in the protruding portion of the spout holder.

  That is, as shown in FIG. 11, the front regulating member 54a has a portion 54d extending along the lower surface of the protruding portion 32b of the spout holder 32, and is located at a position corresponding to the drain hole 32a provided in the protruding portion 32b. A protrusion 54c is provided. The front regulating member 54a has slits 54e extending in the vertical direction at both ends thereof, and the slits 54e are open at the top. On the other hand, the rear regulating member 54b has slits extending in the vertical direction at both ends thereof, and these slits are open at the bottom (see FIG. 14). With this configuration, first, after the front restricting member 54a is disposed with respect to the spout holder 32, the rear restricting member 54b is brought into contact with the rear of the outer surface 32F of the spout holder 32 at a position higher than this position. The rear regulating member 54b can be fitted to the front regulating member 54a by sliding the rear regulating member 54b downward along the outer surface 32F.

  In addition, although the aspect which uses the drain hole 32a for fixing the control member 54 with respect to the spout holder 32 was illustrated here, adhesion | attachment, screwing, a fitting, a double-sided tape, an anti-slip member other than this was illustrated. Any fixing means can be used, such as pinching. For example, a convex portion may be provided on the outer surface 32F of the spout holder 32, a corresponding concave portion may be provided on the inner surface of the regulating member 54, and the regulating member 54 may be fixed to the spout holder 32 by fitting them. A recess may be provided on the outer surface 32F of the spout holder 32, and a corresponding protrusion may be provided on the inner surface of the regulating member 54.

  FIG. 12 illustrates the bottom surface of the regulating member 54. As shown in the figure, the rear regulating member 54b is formed with a groove G in the circumferential direction for accommodating the upper side of the pin P described above. In the present embodiment, both ends of the groove G constitute a contact surface F with the pin P.

  According to the faucet device 100 according to the first embodiment, the rotation range of the rotating body 30 can be limited by the attachment 50. The rotation range of the rotating body 30 can be limited by appropriately selecting the opening H to which the pin P is mounted among the plurality of openings H. Since the attachment 50 is disposed outside the faucet device 100, there is an advantage that the rotation range of the rotating body 30 can be limited without disassembling the faucet device 100.

<Second embodiment>
The attachment 50 according to the first embodiment is a mode in which the rotation range is regulated by attaching the position-changeable pin P to the base member 52 and contacting the contact surface F of the regulating member 54 with the pin P. On the other hand, in the attachment 60 according to the second embodiment, as shown in FIGS. 13 and 14, the extending member 54 f fixed to the regulating member 54 extends toward the base member 52, and the base member 52 comes into contact therewith. It has surface F. In the base member 52, the position of the contact surface F is freely changeable in the circumferential direction, and the rotation range is regulated by the extension member 54f directly contacting the contact surface F of the base member 52. Here, an example in which the extending member 54f directly contacts the contact surface F of the base member 52 is illustrated, but the rotation is restricted by the extension member 54f indirectly contacting the contact surface F via another member. It is good also as an aspect made.

  As shown in FIG. 13, the rear base member 52b has a groove 52h provided on the upper surface and extending in the circumferential direction. The leading end side of the extending member 54f of the regulating member 54 is accommodated in the groove 52h. The rear base member 52b is further formed so that a plurality of slits 52s straddle the groove 52h with a predetermined interval in the circumferential direction. The plate PL constituting the contact surface F is configured to be mounted on the slit 52s. The rotation range of the rotating body 30 can be limited by appropriately selecting the slits 52s for mounting the plate PL. Since the attachment 60 is disposed outside the faucet device, there is an advantage that the rotation range of the rotating body 30 can be limited without disassembling the faucet device.

  In the first and second embodiments described above, a mode in which the pin P and the plate PL are mounted on the rear base member 52b is employed. When such an aspect is adopted, when attaching the attachments 50 and 60 to the faucet device 100, the work can be easily performed without the pin P or the plate PL dropping off from the rear base member 52b. Instead, when the pin P and the plate PL are mounted on the rear regulating member 54b, the pin or the plate may drop from the rear regulating member 54b when the attachment is mounted. In order to prevent this, the opening or slit may be formed relatively strictly according to the size of the pin or plate.
