Description

  The present invention relates to a faucet device having a spout portion that rotates in the left-right direction with respect to a faucet body.

  Conventionally, many users use faucets such as faucets and showers that are originally provided in homes and apartments. However, faucets with excellent design and functionality have been released, and an increasing number of users have removed existing faucets and replaced them with newly purchased faucets.

  For example, when the new faucet 1 is attached to the sink 5 of the kitchen, as shown in FIG. 1A, the spout (water discharge pipe) 2 of the faucet 1 can be rotated in the maximum range in the left-right direction. It is desirable to set the rotation range of the spout 2 so that water is not discharged outside. As shown in FIG. 1B, when the faucet 1 must be installed at a position shifted laterally from the center of the sink 5 (right side in FIG. 1B), the rotation range of the spout 2 is limited. (See FIG. 1 (c)). Patent documents 1-3 disclose a faucet device that can limit the rotation range of the water discharge pipe.

Japanese Patent No. 4854593 Japanese Patent No. 4598559 Japanese Patent No. 4879066

  In the faucet devices described in Patent Documents 1 and 2, a rotation restricting screw or a screw for fixing the rotation restricting part is used. Since these screws are in a position where they can be seen from the outside, there is a problem that the appearance of the faucet device is impaired and the design is lowered.

  By the way, the object required to change the rotation range of the faucet appliance includes not only the faucet appliance newly purchased by the user as described above but also the faucet appliance already provided. For example, when the owner of a condominium changes, or when a trouble occurs in which water is discharged outside the sink, there may be a need to change the rotation range of an existing faucet device.

  Considering whether it is easy to change the rotation range of an existing faucet afterwards or not, the faucet described in Patent Documents 1 and 2 has a screw located on the side. However, it is difficult to work in a state where the faucet device is provided, and it is considered that the faucet device must be removed once. The faucet device described in the cited document 3 requires a large disassembly work of the faucet device because the stopper bolt for restricting the rotation is provided inside the faucet body.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a faucet device that can easily change the rotation range of the spout portion even in a state of being excellent in design and equipped.

  The faucet device of the present invention includes a faucet body having a small diameter portion on which the lever handle is mounted on the upper surface and a faucet portion positioned below the small diameter portion, a cylindrical portion that accommodates the faucet body, and the cylinder A rotating body that extends outward from the side surface of the shaped portion and has a spout portion provided with a water outlet on the tip side, and that rotates in the left-right direction with respect to the faucet body, an outer periphery of the small diameter portion, and a cylindrical portion An annular groove formed between the inner periphery and a projecting portion that protrudes to reach the annular groove and is fixed to the inner periphery of the cylindrical portion and moves in the annular groove as the rotating body rotates. And a fixed ridge that protrudes from the outer periphery of the small-diameter portion of the faucet body to the annular groove and restricts the movement range of the movable overhanging portion, and the movement overhanging portion is accommodated in the annular groove. And one or more key members that narrow the range of movement in the annular groove.

  According to the faucet device, the rotation range of the rotating body can be limited by a simple operation of inserting the key member into the annular groove located at the upper part of the faucet body. Since the annular groove in which the key member is accommodated is located inside the rotating body, the appearance of the faucet device is not impaired and excellent design can be realized. In order to expose the opening of the annular groove, the upper part of the faucet device (for example, a lever handle and a decorative ring in some cases) may be removed, and a large disassembly work is not required. For this reason, even in a state where the faucet device has already been provided, it is possible to easily change the rotation range of the rotating body.

  In the faucet device, the plurality of key members may be accommodated in the annular groove asymmetrically so that a left-side rotation range and a right-side rotation range of the rotation body are different from each other. This configuration is useful when a faucet device must be installed at a position shifted laterally from the center of the sink (see FIG. 1C).

  The faucet device further includes a ring member accommodated in an area defined by the outer periphery of the small diameter portion and the inner periphery of the cylindrical portion and fixed to the cylindrical portion, and the outer periphery of the small diameter portion and the ring member An annular groove may be defined by the inner periphery, and the ring member may be provided with a moving overhang. By adopting a ring member that can be fixed to the cylindrical portion and providing the movable overhang portion on this ring member, there is an advantage that it is not necessary to provide a projection directly on the cylindrical portion. By preparing in advance ring members with different positions and numbers of the moving overhang portions, it is possible to respond more flexibly to changing needs of the rotation range.

  The ring member may have a plurality of grooves on the inner circumference for positioning the key member, and the key member may be fixed to the positioning groove. By providing the positioning groove on the ring member, the key member can be easily mounted at a predetermined position.

  The key member may protrude from the annular groove on the upper end side in a state of being accommodated in the annular groove. By projecting the upper end side of the key member, there is an advantage that the key member once arranged in the annular groove can be easily taken out.

  The faucet device of the present invention may be configured such that the spout is positioned above the faucet body. In this case, the faucet device of the present invention includes a faucet body having a lever handle or a switch for switching between water discharge and water stop, and a rotation extending upward from the faucet body and provided with a moving overhanging portion on the base end surface A spout, a connecting portion provided in the faucet body and rotatably connected to the faucet body, and a moving overhang portion of the rotating spout provided in the connecting portion are accommodated. Arc-shaped grooves, and one or a plurality of key members that narrow the range in which the moving overhanging portion moves within the arc shape by being accommodated in the arc shape.

  According to this faucet instrument, the rotational range of the rotational spout can be limited by a simple operation of inserting the key member into the arc-shaped groove of the connecting portion located at the upper part of the faucet body. Since the key member is accommodated in the arc-shaped groove formed inside the connecting portion, the appearance of the faucet device is not impaired and excellent design can be realized. In order to expose the opening of the arc-shaped groove, it is only necessary to pull up the rotating spout at the top of the faucet device, and no large dismantling work is required. For this reason, even if it is in the state where the faucet instrument was already equipped, the change operation | work of the rotation range of a rotation spout can be performed easily.

  The present invention provides a key member used as a key member of the faucet device. By accommodating the key member in the annular groove or arcuate groove of the faucet device, the rotation range of the rotating body can be easily limited.

And a valve fixing nut 27, and the lever handle 10 is mounted on the upper surface. A water supply pipe 25 a and a hot water supply pipe 25 b are inserted into the lower cylindrical part 22 from the lower side and connected to the water faucet part 25. Connected to the faucet portion 25 is a hose 25c for transferring mixed water in which water and hot water are mixed. The hose 25 c passes through the lower cylindrical portion 22 and exits from the lower end side opening 22 a, and then enters the lower end side opening 22 a again and reaches the spout portion 33 through the side opening 22 b of the lower cylindrical portion 22. .

  As a material of the faucet body 20, a metal or a resin can be used. From the viewpoint of securing the strength of the water faucet, it is preferable to use a metal, and among the metals, a copper alloy is preferable from the viewpoint of excellent productivity (workability). In the case of using a resin, a thermoplastic resin is preferable. Among them, POM (Polyoxymethylene), PA (Polyamide), PPO (Polyphenyleneoxide), PPS (Polyphenylenesulfide) are preferable from the viewpoint of rigidity, fatigue resistance, and slidability. And their fiber reinforcements are more preferred. In the present embodiment, metal and resin are used in combination in consideration of the strength, productivity (workability), and cost of the faucet.

  The rotating body 30 includes a cylindrical portion 31 that accommodates the faucet body 20 and a spout portion 33 that extends outward from the side surface of the tubular portion 31 so as to rotate in the left-right direction relative to the faucet body 20. It is configured. The spout portion 33 is configured to draw out the spout 32 and the hose 25c having a water discharge port 32a on the distal end side, and has a spout holder 34 that detachably holds the base end portion of the spout 32. The spout holder 34 extends outward from the side surface of the tubular portion 31 and rotates together with the tubular portion 31. A decorative ring 39 is attached to the peripheral edge of the upper end of the rotating body 30. In addition, it is set as the structure which can mount | wear with the water purification cartridge (not shown) in the spout 32, and you may enable it to switch the water to be used to raw water or purified water. That is, it is good also as a structure which can switch whether the mixed water from the hose 25c is discharged as it is, or whether the purified water is discharged through the purified water cartridge.

  As a material of the rotating body 30, a metal or a resin can be used. Among metals, a copper alloy is preferable from the viewpoint of productivity (workability), and a copper alloy that is plated from the viewpoint of appearance is more preferable. Among the resins, thermoplastic resins are preferable from the viewpoint of productivity, and those obtained by plating a plating grade resin from the viewpoint of appearance are preferable.

  Next, a mechanism for restricting the rotation of the rotating body 30 will be described first with reference to FIGS. 3 to 8, and then a configuration for changing the rotation range of the rotating body 30 will be described. As shown in FIGS. 3 and 4, the faucet body 20 has a small diameter portion 21 in which the outer diameter of the upper portion is smaller than that of other portions. A ring member 35 is attached to a region defined by the outer periphery of the small diameter portion 21 and the inner periphery of the cylindrical portion 31 of the rotating body 30. The ring member 35 is configured such that a protrusion 31a provided on the inner periphery of the cylindrical portion 31 is fitted in a groove 35a provided on the outer periphery, and rotates together with the rotation of the rotating body 30.

  By disposing the ring member 35 in the region, an annular groove 36 is defined by the outer periphery of the small diameter portion 21 and the inner periphery of the ring member 35. The ring member 35 has a moving overhang portion 35 b that protrudes inward from the inner periphery of the annular groove 36. On the other hand, the small-diameter portion 21 of the faucet body 20 has two fixed raised portions 21a that protrude outward from the outer periphery thereof. The two fixed ridges 21 a are provided so as to sandwich the rotation axis CL of the rotating body 30. As the rotating body 30 rotates, the moving overhanging portion 35b moves in the annular groove 36, and when the moving overhanging portion 35b comes into contact with the fixed raised portion 21a, the rotating body 30 does not rotate any more (FIG. 5). reference). That is, the fixed bulge portion 21a and the movable overhang portion 35b have their respective leading ends in the annular groove 36, and the fixed ridge portion 21a regulates the movement of the movable overhang portion 35b.

  In addition, as a material of the ring member 35, resin or metal can be used, and resin is preferable from the viewpoint of cost. Since the ring member 35 slides with respect to the faucet body 20, among the thermoplastic resins, POM (Polyoxymethylene), PA (Polyamide), PPO (Polyphenyleneoxide), PPS (PPS) from the viewpoint of rigidity, fatigue resistance, and slidability. Polyphenylenesulfide) and their fiber reinforcements are more preferred.

  In order to change the rotation range of the rotating body 30, the key member 38 shown in FIG. 4 is used. By accommodating the key member 38 in the annular groove 36, the range in which the movable overhanging portion 35 b moves in the annular groove 36 can be narrowed. The key member 38 is a rod-like piece (about 10 to 25 mm in length) having a circular cross section, and is made of, for example, resin or metal. From the viewpoint of preventing corrosion due to a potential difference between the key member 38 and other components that are in contact with the key member 38, the key member 38 is preferably made of resin. Among the resins, a thermoplastic resin is preferable from the viewpoint of productivity. The key member 38 is preferably symmetrical vertically and horizontally so that the operator does not have to pay attention to the mounting direction. Grooves 38a are formed at both ends of the key member 38, and the key member 38 can be easily removed by inserting and pulling a flathead screwdriver or the like into the groove 38a. In order to facilitate the work, it is preferable that the upper end side of the key member 38 protrudes from the annular groove 36 while being accommodated in the annular groove 36.

  As shown in FIG. 5, the rotation of the rotating body 30 can be set within a desired range by accommodating the required number of key members 38 in the annular groove 36. 5 shows the rotation range when the number of key members 38 accommodated is 1 on the right side and 0 on the left side. When the middle stage is 1 on the right side and 1 on the left side, the lower stage is 1 on the right side. The case where two on the left side are shown is shown.

  The rotation angle that is changed by inserting the key member 38 into the annular groove 36 is preferably 5 to 25 ° per key member 38. When this angle is less than 5 °, it becomes necessary to insert a large number of key members 38 into the annular groove 36, and the workability is likely to be deteriorated. In addition, the key member 38 itself becomes small, the moldability is poor, and the strength tends to be insufficient. On the other hand, when this angle exceeds 25 °, the amount of change increases and the degree of freedom of angle adjustment tends to decrease. The lower limit value of this angle is more preferably 10 °, and the upper limit value is more preferably 20 °.

  The configuration of the ring member 35 may be devised, and the key member 38 may be provided on the ring member 35 with a positioning function. The ring member 35A shown in FIG. 6 has a plurality of grooves 35c for positioning the key member 38 on the inner periphery. In this case, the key member having the configuration shown in FIG. 7 may be used. The key member 38A shown in the figure is different from the key member 38 described above in that it further includes a plate portion 38b for fitting into the positioning groove 35c.

  According to the ring member 35A having the positioning groove 35c, the key member 38A can be easily mounted at a desired position (see FIG. 8). Further, it is only necessary to attach one key member 38A for each of the right and left rotation restrictions, and the effect of reducing the number of key members 38A and the amount of work is also achieved (see FIG. 8B). The ring member 35 </ b> A and the key member 38 </ b> A may be employed in modified examples and a second embodiment described later.

  According to the faucet device 50, the rotation range of the rotating body 30 can be limited by a simple operation of inserting the key member 38 (38 </ b> A) into the annular groove 36 positioned at the upper part of the faucet body 20. Since the annular groove 36 in which the key member 38 (38A) is accommodated is located inside the faucet device 50, the appearance of the faucet device 50 is not impaired and excellent design can be realized. In order to expose the opening of the annular groove 36, the lever handle 10 and the decorative ring 39 may be removed, and a large disassembly work is not required. For this reason, even if it is the state already equipped, the change operation | work of the rotation range of the rotary body 30 can be performed easily.
