Description

The present invention is an opening/closing device for a water faucet device that opens and closes a water channel and adjusts the flow rate, and is used in a universal water faucet device in which a water discharge pipe at a water inlet of a water faucet is rotatable in a horizontal plane. The present invention relates to a device and a universal faucet device provided with the same.

2. Description of the Related Art As a water faucet device used in kitchens for home use and large sinks for commercial use, there is a universal water faucet device in which a water outlet of a water faucet attached to a water supply pipe is provided with a water discharge pipe rotatable in a horizontal plane. A universal faucet device can change the water discharge position by rotating a water discharge pipe with respect to a water faucet fixed to a top surface of a sink or a wall surface. A general adjustable water faucet device opens and closes the flow path and adjusts the flow rate by operating a handle or lever, in addition to rotating the water discharge pipe for changing the water discharge position.

Handles and levers for opening and closing the flow path and adjusting the flow rate are attached to a part of the faucet fixed to the ceiling or wall on the back side of the sink. For this reason, in the flexible faucet device used in large commercial sinks, when opening and closing the flow path and adjusting the flow rate, the operator extends his arm from the front side of the sink and operates the handle or lever on the back side of the sink. This not only complicates the work, but also tends to waste water. Also, in a universal water faucet device used in a home kitchen, etc., when opening and closing the flow path and adjusting the flow rate, the operation of the handle or lever is separate from the turning operation of the water discharge pipe for changing the water discharge position. is required, and water is likely to be wasted.

Therefore, as a conventional flexible water faucet device, there has been proposed one in which a valve mechanism for opening and closing a flow path according to the rotation of the water discharge pipe is provided at the rotary connecting portion between the water supply port of the water tap and the water discharge pipe. . According to this configuration, it is possible to open and close the cap quickly and easily, thereby further saving water (see, for example, Patent Document 1).

Japanese Utility Model Laid-Open No. 06-008464

However, the universal faucet device described in Patent Document 1 opens and closes the opening in the flow path by the up-and-down movement of the sphere with which the free end of the seesaw, which swings around the supporting end as the water discharge pipe rotates, abuts. Therefore, it is difficult to give sufficient strength to the seesaw itself and the members that transmit the turning force of the water discharge pipe to withstand the water pressure in the flow channel, and it is difficult to open and close the flow channel and adjust the flow rate. There are problems that cannot be realized for a long time. Moreover, it cannot be attached to an existing faucet device, and the faucet device needs to be replaced.

An object of the present invention is to enable the opening and closing of the flow path and the adjustment of the flow rate reliably over a long period of time by rotating the water discharge pipe with respect to the water faucet by attaching it to the existing water faucet device. To provide an opening/closing device for a universal faucet device which can be easily made and has a high water-saving effect, and a universal faucet device having the same.

The opening/closing device for a universal faucet device of the present invention has a connecting portion fixed to a water supply pipe or a spout of a water faucet attached to the water supply pipe on the upstream end side, and a part of the inner peripheral surface in the axial direction is fully A cylindrical body having an abutting portion protruding radially over the circumference, and a spindle joint axially inserted into the body from the downstream end side of the body and exposed to the outside of the body from the downstream end side. a spindle joint having a coupling portion to which the base end of the water discharge pipe is fixed at the exposed end. The spindle joint consists of a male threaded portion that is screwed into a female threaded portion inside the main body, a gap portion upstream of the male thread portion whose outer diameter is smaller than the inner peripheral surface of the main body, and a portion inside the main body upstream of the gap portion. It has a valve member that selectively abuts on the abutting portion in the axial direction to open and close the upstream side of the gap, and a communicating portion that communicates from the gap to the water discharge pipe via the connecting portion.

A spindle joint having a male threaded portion screwed to a female threaded portion of the main body moves in the axial direction inside the main body when it is rotated about the axis of the main body integrally with the water discharge pipe whose base end is fixed to the coupling portion. Axial movement of the spindle joint causes the valve member of the spindle joint to selectively axially abut against an abutment within the body to open and close the upstream side of the gap.

When the water discharge pipe is rotated in a direction in which the valve member moves away from the abutting portion from a state in which the valve member abuts against the abutment portion to close the upstream side of the gap portion, the upstream side of the gap portion is opened. . The water supplied from the water supply pipe or the spout of the water tap attached to the water supply pipe flows through the gap between the abutment part and the valve member inside the main body to the communication part, and is discharged from the water discharge pipe. be. From a state in which the valve member is separated from the abutting portion to open the upstream side of the communicating portion, when the water discharge pipe is rotated in a direction in which the valve member abuts on the abutting portion, the upstream side of the gap is closed. . Water supplied from the water supply pipe or the spout of the water tap attached to the water supply pipe is stopped between the contact portion and the valve member without flowing into the gap.

The water faucet device is opened and closed by rotating the water discharge pipe in the horizontal plane of the faucet device. When the faucet device is opened and closed, it is only necessary to bring a part of the hand or arm into contact with the water discharge pipe, and there is no need to grip and operate the handle or lever with fingers.

In this configuration, a first contact portion and a second contact portion are provided at two locations in the axial direction inside the main body, and the valve member contacts the first contact portion as the spindle joint rotates in one direction. It is possible to move from the position to the position where it abuts on the second abutment part via an intermediate position where it abuts neither the first abutment part nor the second abutment part.

While rotating from one end side to the other end side in the rotation range of the water discharge pipe, the water supplied from the water supply pipe or the water discharge port of the water tap attached to the water supply pipe is stopped from the water discharge state through the water discharge state. Can be made into water.

The gap may include a portion of the male threaded portion in the circumferential direction, and at least a portion of the communicating portion may open to the portion of the male threaded portion in the circumferential direction of the gap. The axial length of the body and spindle joint can be shortened.

According to the present invention, by attaching it to an existing faucet device, it is possible to reliably open and close the flow path and adjust the flow rate over a long period of time by rotating the water discharge pipe with respect to the water tap. It can be easily done and a high water saving effect can be obtained.

Hereinafter, an opening/closing device for a universal faucet system according to an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, an opening/closing device 10 for a universal faucet system according to the first embodiment of the present invention is fixed to a wall surface 110 on the back side of a sink 100 via a tightening nut 150 as an example, and is connected to a water supply pipe. It is attached to a hydrant 120 connected to 140 . The wall surface 110 is not limited to facing the front of the worker with the sink 100 interposed therebetween, and may be positioned on the left or right side of the worker. A holding member 3 (not shown in FIG. 1 ) arranged at the upstream end of the main body 1 is connected to the spout 121 of the water tap 120 via a cap nut 41 . A connecting portion 6 (not shown in FIG. 1) is exposed outside the main body 1 from the downstream end side of the main body 1 in the spindle joint 2 which is axially inserted into the main body 1 from the downstream end side of the cylindrical main body 1. ) is fixed to the base end portion 131 of the water discharge pipe 130 via the cap nut 42 .

The spindle joint 2 is held within the main body 1 so as to be rotatable about the axis of the main body 1 within a predetermined range. The water discharge pipe 130 rotates integrally with the spindle joint 2 about the axis of the main body 1 within a predetermined range. The water discharge position from the water discharge port 132 of the water discharge pipe 130 can be changed within the horizontal plane. The universal faucet device opening/closing device 10 is used with the handle 122 of the water faucet 120 rotated to the open side. The opening/closing device 10 for a universal faucet device does not necessarily have to be connected to the water tap 120 .

As shown in FIGS. 2A and 2B , the universal faucet device opening/closing device 10 includes a main body 1 , a spindle joint 2 , and a cap nut 41 . The main body 1 has a holding member 3 at its upstream end, and has a tubular shape with open upstream and downstream ends in the axial direction. In FIG. 2, the axial upper side and lower side of the main body 1 are the upstream side and the downstream side of the water channel, respectively. An upstream female threaded portion 11, a contact portion 12, and an intermediate female threaded portion 13 are formed on the inner peripheral surface of the circular cross section of the main body 1 from the upstream side to the downstream side. The contact portion 12 radially protrudes from the inner peripheral surface of the main body 1 in a flange shape over the entire circumference.

The holding member 3 has an annular shape with both ends in the axial direction open, and has a male threaded portion 31 formed on the downstream end side of the outer peripheral surface and an outward flange portion 32 formed on the upstream end side of the outer peripheral surface. The retaining member 3 is inserted into the cap nut 41 in a state in which the outward flange portion 32 is brought into contact with the stepped portion 41A of the cap nut 41 from the upstream side, and then the male threaded portion 31 exposed from the downstream side is connected to the upstream side female thread. It is integrally attached to the upstream end of the main body 1 with an O-ring 81 interposed therebetween by being screwed to the portion 11 , thereby forming a part of the main body 1 . By forming the holding member 3 as a separate member from the main body 1 and then integrally attaching it to the main body 1, the main body 1 can be easily manufactured.

The holding member 3 holds the cap nut 41 at the upstream end of the main body 1 so as to be rotatable about its axis, and together with the cap nut 41 constitutes the connecting portion 4 of the present invention. The main body 1 is fixed together with the holding member 3 to the water supply pipe or water faucet with the packing 41C interposed therebetween by screwing the female threaded portion 41B of the cap nut 41 onto the male threaded portion of the water supply pipe or water faucet.

The spindle joint 2 has a tubular shape with an open downstream end, and a concave portion 21 open to the upstream side is formed along the entire circumference of the upstream end. 22, a collar portion 23 is formed. The spindle joint 2 is inserted into the main body 1 from the downstream end of the main body 1 and is rotatably held in the main body 1 by screwing the spindle male threaded portion 22 into the intermediate female threaded portion 13 of the main body 1 . The recess 21 holds the valve member 51 inserted from the upstream side. A threaded hole 29 is formed in the upstream end face of the spindle joint 2 . The valve member 51 is, for example, an annular packing, and is fixed to the spindle joint 2 by being sandwiched by a press screw 52 that is screwed into the screw hole 29 from the upstream side of the spindle joint 2 . The outer peripheral surface of the collar portion 23 is in contact with the inner peripheral surface of the main body 1 with an O-ring 82 interposed therebetween.

The spindle joint 2 moves in the axial direction as it rotates within the main body 1 due to screw engagement between the spindle male threaded portion 22 and the intermediate female threaded portion 13 . Movement of the spindle joint 2 toward the upstream side within the main body 1 is restricted by the contact between the valve member 51 and the contact portion 12 (see FIG. 2A). A set screw 14 is screwed into the downstream end of the main body 1 from the outer peripheral surface with a part thereof exposed inside the main body 1 . The movement of the spindle joint 2 to the downstream side within the main body 1 is restricted by the portion of the set screw 14 exposed within the main body 1 coming into contact with the downstream side surface of the flange 23 (see FIG. 2(B)). .

The relationship between the amount of rotation and the amount of axial movement of the spindle joint 2 with respect to the main body 1 can be adjusted by adjusting the pitches of the intermediate female threaded portion 13 and the spindle male threaded portion 22 .

The downstream end of the spindle joint 2 has an annular shape and is exposed to the outside from the downstream end of the main body 1. A coupling male threaded portion 26 is formed on the outer peripheral surface, and an enlarged diameter portion 27 and a tapered portion 28 are formed on the inner peripheral surface. is formed. A cap nut 42 (see FIG. 1) held at the base end portion 131 of the water discharge pipe 130 is screwed to the coupling male thread portion 26 . The enlarged diameter portion 27, which is a portion whose inner diameter is enlarged on the downstream side of the taper portion 28, holds the split ring 83, the pressing ring 84 and the packing 85, and together with the coupling male thread portion 26 and the taper portion 28, the coupling portion 6 of the present invention. Constitute.

When the cap nut 42 is screwed onto the coupling male threaded portion 26, the water discharge pipe 130 moves upstream together with a collar (not shown) fitted to its outer peripheral surface. The split ring 83 , the pressing ring 84 and the packing 85 are pressed upstream by the collar, and the split ring 83 contacts the tapered portion 28 to reduce its diameter and press against the peripheral surface of the base end portion 131 of the water discharge pipe 130 . A base end portion 131 of a water discharge pipe 130 is fixedly connected to the connecting portion 6 while maintaining a watertight state, and the water discharge pipe 130 rotates integrally with the spindle joint 2 .

A gap 7 is formed between the contact portion 12 and the intermediate female thread portion 13 on the inner peripheral surface of the main body 1 and is sandwiched between the outer peripheral surface of the spindle joint 2 . The spindle joint 2 has an opening 24 that is open to the outer peripheral surface at a portion of the male threaded portion 22 of the spindle and a portion of the gap 7, and a communicating portion 25 that communicates between the opening 24 and the downstream end face inside. formed. The communication portion 25 communicates with the water discharge pipe 130 attached to the joint portion 6 .

2, the gap 7 includes a portion of the spindle male threaded portion 22 in the circumferential direction, and at least a portion of the communicating portion 25 has an opening 24 in the circumferential portion of the spindle male threaded portion 22 in the gap 7. . By configuring in this way, it is possible to shorten the overall axial length of the opening/closing device 10 for a universal faucet device while ensuring a sufficient amount of water to be discharged from the water discharge pipe 130 . However, it is not limited to this, and the opening 24 can be provided only within the gap 7 .

As shown in FIG. 3, when the water discharge pipe 130 is rotated in the horizontal plane from the position indicated by the dashed line in the drawing, the spindle joint 2 is integrated with the water discharge pipe 130 within the main body 1 of the universal faucet device opening/closing device 10. It moves in the axial direction while rotating. The spindle joint 2 is positioned on the most upstream side shown in FIG. 2(A) within the range of movement in the axial direction when the water discharge pipe 130 is at the position indicated by the broken line in FIG. When it rotates clockwise, it moves downstream, and when the water discharge pipe 130 is at the position indicated by the solid line in FIG. 3, it is positioned at the most downstream side shown in FIG.

When the water discharge pipe 130 is at the position indicated by the dashed line in FIG. 3 and the spindle joint 2 is at the most upstream position shown in FIG. , the upstream side of the gap 7 is closed. The water that flows from the water supply pipe to the upstream end side in the main body 1 via the water tap 120 and the inside of the connection portion 4 is blocked by the contact portion 12 and the valve member 51 and does not flow into the gap 7. Water is not discharged from the water discharge pipe 130 .

When the water discharge pipe 130 is rotated counterclockwise from the position shown by the dashed line in FIG. 3, the spindle joint 2 moves downstream from the most upstream position shown in FIG. The contact with 51 is released, and the upstream side of gap 7 is opened. Water that flows from the water supply pipe to the upstream end side in the main body 1 via the water tap 120 and the inside of the connection portion 4 flows into the gap 7, and flows from a part of the spindle male thread portion 22 and a part of the gap 7 to the opening 24. And water is discharged from the water discharge pipe 130 via the communication part 25 .

When the water discharge pipe 130 rotates to the position indicated by the solid line in FIG. 3, the spindle joint 2 reaches the most downstream position shown in FIG. and the upstream side of the gap 7 is completely opened. The water flowing from the water supply pipe to the upstream end side in the main body 1 via the water tap 120 and the inside of the connection part 4 is discharged from the water discharge pipe 130 via the gap 7, the opening 24 and the communication part 25 at the maximum amount. be done.

When the water discharge pipe 130 is rotated clockwise to the position indicated by the dashed line in FIG. 3, the contact portion 12 and the valve member 51 are separated until the spindle joint 2 reaches the most upstream position shown in FIG. 2(A). gradually narrows, and when the spindle joint 2 reaches the most upstream position shown in FIG. .

The water supply channel can be opened and closed between the contact portion 12 and the valve member 51 by rotating the water discharge pipe 130 in the horizontal plane. It is possible to easily open/close the channel and adjust the amount of spouted water without operating the handle 122 of the water tap 120 .

The counterclockwise rotation range of the water discharge pipe 130 in FIG. 3 is defined by the position of the set screw 14 in the axial direction of the main body 1 and the position of the collar portion 23 in the axial direction of the spindle joint 2 . Even if the water discharge pipe 130 rotates counterclockwise beyond the position indicated by the solid line in FIG. 3, the water discharge state from the water discharge pipe 130 does not change. Further, by changing the axial thickness of the valve member 51 or the recess 21, the water discharge pipe 130 can be changed from the position of the water stop state indicated by the broken line in FIG. 3 to the position of the maximum water discharge state indicated by the solid line in FIG. can be adjusted.

In FIGS. 2A and 2B, the contact area with the valve member 51 is reduced by forming a concave portion along the entire circumference of the downstream end face of the contact portion 12, but this is not the only option. However, it can have any shape on the condition that it can reliably contact the valve member 51 over the entire circumference.

Further, the upstream end surface 16 of the portion of the spindle joint 2 exposed to the outside downstream from the main body 1 abuts against the downstream end surface 17 of the main body 1, thereby restricting the movement of the spindle joint 2 toward the upstream side and forming an annular shape. Excessive elastic deformation of the valve member 51, which is a packing, can be prevented.

Further, the setscrew 14 is arranged in the main body 1 so as to be exposed at a position facing between the spindle male threaded portion 22 and the collar portion 23 on the outer peripheral surface of the spindle joint 2, and the spindle is held by contact with the spindle male threaded portion 22. The movement of the joint 2 to the downstream side may be restricted.

In addition, by making the intermediate female threaded portion 13 and the spindle male threaded portion 22 reverse-threaded, the water discharge pipe 130 is shifted from the position shown by the solid line in FIG. It is also possible to allow water to be discharged from the water discharge pipe 130 when it is rotated clockwise.

As shown in FIGS. 4(A) to 4(C), an opening/closing device 20 for a universal faucet system according to a second embodiment of the present invention replaces the valve member 51 of the opening/closing device 10 for a universal faucet device with a second It includes a first valve member 251A and a second valve member 251B, a contact portion 212 instead of the contact portion 12, and the set screw 14 is omitted. , the same reference numerals are given and the description thereof is omitted.

The first valve member 251A housed in the downstream recess 221A and the second valve member 251B housed in the upstream recess 221B are, for example, annular packings, which are arranged at positions sandwiching the contact portion 212 in the axial direction. ing. The upstream recessed portion 221B is formed on the downstream side surface of the support member 221 . The support member 221 has a disc shape screwed onto the pressing screw 52, and rotates and moves integrally with the spindle joint 2 together with the second valve member 251B. The contact portion 212 radially protrudes from the inner peripheral surface of the main body 1 over the entire circumference and has a cross-sectional shape that is symmetrical about the axial direction.

In the opening/closing device 20 for a universal faucet device, the contact portion 212 is positioned in the axially intermediate portion of the gap 7, and the first valve member 251A and the second valve member 251B are positioned within the gap 7 so that the contact portion 212 is in contact with the contact portion 212. Located downstream and upstream.

The first valve member 251A contacts the downstream side surface of the contact portion 212 while the spindle joint 2 is positioned at the most upstream position shown in FIG. When the spindle joint 2 rotates integrally with the water discharge pipe 130 and reaches the most downstream position shown in FIG. 4(B) between the most upstream position shown in FIG. 4(A) and the most downstream position shown in FIG. 4(C), the first The valve member 251A and the second valve member 251B do not contact the downstream side surface and the upstream side surface of the contact portion 212 .

As shown in FIG. 5, when the water discharge pipe 130 is rotated in the horizontal plane from the position indicated by the dashed line in the drawing, the spindle joint 2 is integrated with the water discharge pipe 130 within the main body 1 of the universal faucet device opening/closing device 20. It moves in the axial direction while rotating. The spindle joint 2 is positioned at the most upstream position shown in FIG. 4A or the most downstream position shown in FIG. 4(B) when the water discharge pipe 130 is at the position indicated by the solid line in FIG.

5, and the spindle joint 2 is located at the most upstream position shown in FIG. 4(A) or the most downstream position shown in FIG. 4(C), the contact portion 212 and the first valve member 251A or the second valve member 251B are in contact with each other over the entire circumference, and the downstream side or upstream side of the contact portion 212 is closed at the gap 7 . The water flowing from the water supply pipe to the upstream end side in the main body 1 via the water tap 120 and the inside of the connection portion 4 is stopped between the contact portion 212 and the first valve member 251A or the second valve member 251B. As a result, the water does not flow into the gap 7 on the downstream side of the contact portion 212 and is not discharged from the water discharge pipe 130 .

When the water discharge pipe 130 is rotated counterclockwise or clockwise to the position indicated by the solid line in FIG. 5, the spindle joint 2 moves to the intermediate position shown in FIG. 251A and the second valve member 251B are released, and the upstream side of the gap 7 is opened. Water that flows from the water supply pipe to the upstream end side in the main body 1 via the water tap 120 and the inside of the connection portion 4 flows into the gap 7, and flows from a part of the spindle male thread portion 22 and a part of the gap 7 to the opening 24. And water is discharged from the water discharge pipe 130 via the communication part 25 .

By rotating the water discharge pipe 130 in one direction within the angle range of (R2+R3) in the horizontal plane, the water supply channel can be opened, closed, and closed again. Also, it is possible to more easily open/close the channel and adjust the amount of water spouted without operating the handle 122 of the water tap 120 arranged on the far side of the sink 100 . In addition, the water tap 120 is not limited to being arranged at a position facing the front of the worker with the sink 100 interposed therebetween, and may be arranged on the left side or the right side of the worker.

The angles R2 and R3, which are the rotation ranges of the water discharge pipe 130 in the horizontal plane, are defined by at least one of the contact portion 212, the first valve member 251A or the second valve member 251B, or the downstream recess 221A or the upstream recess 221B. It can be adjusted by changing the thickness in the axial direction, and the angles R2 and R3 do not necessarily have to be the same.

In the example shown in FIGS. 4A to 4C, the set screw 14 of the universal faucet device opening/closing device 10 is omitted, but the spindle joint 2 is removed by contact with the spindle male threaded portion 22 or the collar portion 23. A setscrew 14 may be provided to restrict movement of the second valve member 251B to the downstream side to prevent excessive elastic deformation of the second valve member 251B due to contact with the contact portion 212. FIG.

In addition, the contact area between the first valve member 251A and the second valve member 251B is reduced by forming concave portions over the entire periphery of the downstream end face and the upstream end face of the contact portion 212, but this is not the only option. Any shape can be used on the condition that the first valve member 251A and the second valve member 251B can be reliably contacted over the entire circumference.

Further, the upstream end surface 16 of the spindle joint 2 exposed to the outside downstream from the main body 1 abuts against the downstream end surface 17 of the main body 1, thereby restricting the movement of the spindle joint 2 toward the upstream side. Excessive elastic deformation of the first valve member 251A due to contact with the contact portion 212 may be prevented.

As shown in FIGS. 6(A) to 6(C), a universal faucet device opening/closing device 30 according to a third embodiment of the present invention includes a contact portion 12 of the universal faucet device opening/closing device 10 and a holding member. 3 and the valve member 51, a first contact portion 312A, a holding member 303, a first valve member 351A and a second valve member 351B are provided, the setscrew 14 is omitted, and the rest of the configuration is that of a universal faucet. Since it is the same as the device opening/closing device 10, the same reference numerals are given and the description is omitted.

The first valve member 351A and the second valve member 351B housed in the downstream side recessed portion 321A and the upstream side recessed portion 321B are, for example, annular packings, and are arranged between the first contact portion 312A and the holding member 303 in the axial direction. are placed in The downstream recessed portion 321A and the upstream recessed portion 321B are formed on the downstream side surface and the upstream side surface of the support member 321, respectively.

The support member 321 has a disc shape screwed onto the pressing screw 52, and rotates and moves integrally with the spindle joint 2 together with the first valve member 351A and the second valve member 351B. It is also possible to omit the support member 321 or form an annular body with a smaller diameter, and integrally form the first valve member 351A and the second valve member 351B.

The first contact portion 312A radially protrudes from the inner peripheral surface of the main body 1 over the entire circumference. The holding member 303 is formed as a separate member from the main body 1 and then fixed to the upper end portion of the main body 1 to constitute a part of the main body 1. A second contact portion 312B is formed.

In the universal faucet device opening/closing device 30 , the first contact portion 312 A is positioned in the axially intermediate portion of the gap 7 , and the second contact portion 312 B is positioned in the most upstream portion of the gap 7 . The first valve member 351A and the second valve member 351B are positioned within the gap 7 upstream of the first contact portion 312A and downstream of the second valve member 351B, respectively.

By forming the second contact portion 312B on the holding member 303, the opening/closing device 30 for a universal faucet device can be used for the main body 1 as compared with a configuration in which the second contact portion 312B is formed on a part of the main body 1.
