  Today, as a faucet device provided in a general household, particularly in a sink, there are a flow path provided inside the main body, a flow rate adjusting valve for opening and closing the flow path, and a flow rate adjusting valve connected to the flow rate adjusting valve. A currant provided with a lever provided on a main body so as to be rotatable is often used. In this currant, the flow rate can be easily adjusted only by the upper and lower sides of the lever, but if the lever is lifted too much, the faucet is easily fully opened, resulting in wasted water.

Therefore, the water-saving tool shown in patent document 1 is proposed. This water-saving device is characterized by a structure that can be switched to a maximum flow rate and a medium flow rate with a single touch by a movable water-saving stopper. Specifically, a stopper that can be tilted is installed at the water supply position and the hot water supply position of the lever faucet, and the rotation angle of the lever is adjusted by bringing the stopper into contact with the base 12 of the lever. In order to stop at the position before the stopper is fully opened and to make the lever pivotable to the fully-open position of the faucet, the stopper is tilted down.
However, in the water-saving device of Patent Document 1, the adjustment of the flow rate is limited to the adjustment of whether the stopper is raised or lowered, and the flow rate cannot be set at an arbitrary position. Moreover, in order to make the faucet fully open, it is necessary to tilt the stopper one by one, and it has not been possible to make it fully open with one touch.

  The present invention includes a flow path provided inside the main body, a flow rate adjusting valve that opens and closes the flow path, and a lever that is connected to the flow rate adjusting valve and is pivotable up and down. It is intended to provide a water-saving device that can prevent wasteful use of water due to the lever being raised too much, and in particular, the opening of the faucet by the lever can be easily set to the amount of water according to the user's preference. The purpose is to provide such a water-saving device. Further, when the faucet is to be fully opened, a water-saving device is provided that can easily release the stopper and rotate the lever to the upper limit.

The invention according to claim 1 of the present application provides a flow path provided inside the main body, a flow rate adjusting valve that opens and closes the flow path, and a flow rate adjusting valve that is connected to the flow rate adjusting valve and is rotatable up and down. In a water-saving device that is attached to and used with a curran provided with a lever provided, it has a support column whose base end side is fixed, and a stopper provided so as to be movable in the vertical direction with respect to this support column.
The stopper includes an abutting portion that stops the upward rotation of the lever by abutting against the upper portion of the lever, a guided portion that is guided so as to be movable in the vertical direction with respect to the column, and a stopper that supports the column. A positioning portion that is fixed at an arbitrary position with respect to
The lever is stopped in a state before the faucet is fully opened by fixing the stopper to the support column at a position where the contact portion of the stopper contacts within the rotation range of the lever. A water-saving device for currants is provided.
The invention according to claim 2 of the present application includes an elastic body that urges the stopper upward between the stopper and the column, and the positioning portion fixes the stopper against the urging force of the elastic body. The curling water-saving device according to claim 1, further comprising a locking device, wherein the stopper is lifted by the biasing force of the elastic body by releasing the locking by the locking device. is there.

In the water-saving device for currants according to the present invention, the stopper can be moved in the vertical direction with respect to the support, and the contact portion that stops the upward rotation of the lever by contacting with the upper portion of the lever. Since the guided part is provided with a positioning part for fixing the stopper at an arbitrary position with respect to the support column, when the curan lever is lifted, the lever is provided on the stopper. Since it does not lift any further after it abuts against the portion, the faucet will not be opened carelessly, and waste of water due to excessive lifting of the lever can be prevented. Moreover, since the stopper can be fixed at any position with respect to the column by the positioning portion, the opening of the faucet by the lever can be easily set to the amount of water according to the user's preference.
Furthermore, in the water-saving device for currants according to the invention of claim 2, in addition to the above effect, the stopper is raised by the biasing force of the elastic body by releasing the locking by the locking device. When it is desired to fully open the lever, the stopper can be easily released and the lever can be rotated to the upper limit.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a water saving tool for curans according to an embodiment of the present invention, and FIG. 2 is an explanatory view of the internal structure of the water saving tool for curans.

  As shown in FIG. 1, this water-saving device is used by being attached to a single lever currant 91 that is frequently used in a sink in a general household. The currant 91 is connected to the flow path (not shown) provided inside the main body 92, a flow rate adjusting valve (not shown) for opening and closing the flow path, and connected to the flow rate adjusting valve and rotated up and down. A lever 93 provided in the main body is provided, and a faucet 94 that discharges water in accordance with the operation of the lever. The currant 91 may be for supplying only water, and the temperature of the water discharged from the faucet 94 is adjusted by rotating the lever 93 in the left-right direction with a hot and cold water mixing tap provided inside. It may be what you did.

  As shown in FIG. 2, the water-saving device includes a column 11 and a stopper stopper 21 that is attached to the column 11 so as to be movable up and down.

  The support column 11 includes a base portion 12 and a column portion 13. The base 12 is detachably fixed to the lower part of the main body 92. In this example, the lower part of the main body 92 is sandwiched from the front and rear by the front part 14 and the rear part 15 that are substantially semicircular in plan view. The front part 14 and the rear part 15 are connected and fixed by screws 16. This detachable fixing structure can be implemented with various modifications, and one end of the front portion 14 and one end of the rear portion 15 are pivotally connected by a hinge, and the other ends are fixed by a detachable fixing means. You may do it. In addition, a part that can be expanded and contracted may be provided so that it can be adjusted according to the size of the main body 92.

  The column portion 13 has a base end (lower end) fixed to the base portion 12, in this example, a rear portion 15. The column portion 13 is provided at a right angle with respect to the base portion 12 so that the tip (upper end) of the column portion 13 extends upward, and preferably stands substantially vertically when attached to the currant 91. A rack 17 is formed in the column portion 13 in the vertical direction. In this example, it is provided at the rear part (rear side) of the column part 13, but it may be formed on the front, left and right or the entire surface. The structure of the base 12 can be changed as appropriate. For example, as shown in FIGS. 3A and 3B, the base 12 may be set on the shaft of the main body 92 of the currant 91, as shown in FIGS. As shown in FIG. 4C, the base 12 can be formed as a plate having a flat bottom surface and can be fixed to the upper surface of the sink to which the currant 91 is attached with an adhesive or a screw. As shown, the base 12 may have a partially open arc shape that is forcibly fitted to the main body 92 of the currant 91.

  Next, the stopper 21 is movable in the vertical direction with respect to the contact portion 22 that stops the upward rotation of the lever by contacting the upper portion of the lever 93 of the currant 91 and the column portion 13 of the column 11. And a positioning portion 31 for fixing the stopper 21 to the support column 11 at an arbitrary position.

  The guided portion 23 has a cylindrical shape with an open lower end, and the column portion 13 is mounted inside the cylindrical shape of the guided portion 23. In this mounting, the column portion 13 may be inserted from the lower end opening of the guided portion 23, the guided portion 23 can be divided in the front-rear direction, and the column portion 13 is mounted inside in the divided state. Thereafter, the assembling method may be changed as appropriate, for example, by fixing the front and rear divided members with screws or the like. In addition, the guided portion 23 only needs to be slidable up and down with respect to the column portion 13. In this example, the column portion 13 is inserted into the guided portion 23. Alternatively, an insertion hole may be formed in the column portion 13 in the vertical direction, and the guided portion 23 may be inserted into the insertion hole. Also, the column part 13 and the guided part 23 slide in the vertical direction, for example, one is composed of a rod-shaped body having a T-shaped cross section and the other is composed of a rod-shaped body having a C-shaped cross section. Any structure that can be combined can be implemented with appropriate modifications.

  Next, the abutting portion 22 is provided at the upper portion of the guided portion 23, extends forward from the guided portion 23, and is disposed so as to be positioned above the lever 93 in the attached state to the currant 91. It is ranked. The size of the contact portion 22 in the front-rear direction is set to be shorter than that of the lever 93 so that even if the stopper 21 is provided, only the lever 93 can be held by hand. Specifically, the abutting portion 22 is preferably about half the length of the lever 93 in the front-rear direction.

  Further, in the case of a hot and cold water mixing tap, the lever 93 often adjusts the mixing amount of hot water and water by rotating left and right. Therefore, the contact part 22 is formed in a substantially fan shape in plan view. More preferably, the tip edge 24 is preferably arcuate with the center on the extension line of the rotation shaft of the main body 92 in a state where it is mounted on the currant 91, but it is not necessarily set geometrically. It suffices if the lever 93 can come into contact with the contact portion 22 within the rotation range of the lever 93. A shock absorbing member 26 made of elastic rubber or synthetic resin is arranged at the contact portion that contacts the lever 93 on the lower surface side of the contact portion 22, and even when the lever 93 strongly contacts, It is desirable to relieve damage and prevent scratches.

  A viewing window 25 is formed at the center of the contact portion 22. The viewing window 25 corresponds to the display provided on the upper surface of the lever 93, and the display of the lever 93 is displayed even when the stopper 21 is arranged above the lever 93. However, it may be implemented as a whole plate-shaped without providing the viewing window 25, or may be formed entirely of a transparent synthetic resin or the like. .

  The stopper 21 is fixed at a predetermined position with respect to the support column 11 by the positioning portion 31, so that when the lever 93 is lifted to discharge water, the contact portion 22 and the lever 93 come into contact with each other. The stop position of the lever 93 can be changed and the water amount of the currant 91 can be adjusted by operating the positioning portion 31 and changing the vertical position of the stopper 21. In this example, the positioning portion 31 is provided in the guided portion 23, and the positioning portion 31 is provided with a locking portion 32 that can be engaged with and released from the rack 17 of the support column 11, and the locking portion 32 is always connected to the rack 17. Urging means 33 such as a spring urging in a direction in which the urging means abuts against the urging member 33, and an operation portion 34 for separating the locking portion 32 from the rack 17 against the urging force of the urging means 33. More specifically, the locking portion 32 and the operation portion 34 are integrally formed and attached to the guided portion 23. For attachment, the guided portion 23 is pivotally supported between the locking portion 32 and the operating portion 34, and the guided portion 23 is locked to the rack 17 by the urging force of the urging means 33, and the operating portion operating portion 34. Is projected as a push button so that it can be operated from the guided portion 23 by hand. Then, by pushing the operating portion 34, the locking portion 32 is retracted from the rack 17, and the guided portion 23 is in a free state. In this state, the guided portion 23 is moved up and down to adjust the position. When the new position is determined, the locking portion 32 is locked at the new position of the rack 17 by releasing the hand from the operation portion 34. The specific structure of the positioning portion 31 can be changed as appropriate. In addition to the push button type described above, a slide button may be used, or the locking portion 32 and the operation portion operation portion 34 may be separated and interlocked. Good.

  Next, urging means for urging the stopper 21 upward at all times may be provided. Specifically, a spring 28 such as a coil spring is provided between the column 11 and the guided portion 23, and the guided portion 23 is urged upward with respect to the column 11. More specifically, a recessed spring receiving portion 18 is provided at the upper end of the column portion 13, and a recessed spring receiving portion 29 is provided at the closed top portion of the cylindrical guided portion 23, and the spring 28 is arranged between them. Rank. Thereby, the stopper 21 is urged upward, and when the locking by the positioning portion 31 is released, the stopper 21 is raised by the spring 28. This rising position is convenient because the currant 91 can be easily fully opened by making it higher than the fully open position of the faucet, that is, the uppermost position of the lever 93. At the upper end of the rack 17, a stopper 19 is provided to prevent the locking portion 32 from coming off above the rack 17, or at appropriate locations between the guided portion 23 and the column 11. It is desirable to prevent the guided portion 23 from coming off from the support 11 by providing an engaging portion to be engaged. Further, in this example, as described above, when the operating portion 34 is pushed in, the locking portion 32 is retracted from the rack 17 and the guided portion 23 is in a free state, and when the hand is released from the operating portion 34, the engaging portion 32 is engaged. However, a locking means that is lightly engaged is provided between the operation portion 34 and the guided portion 23, and when the operation portion 34 is lightly pressed and then released, the guided portion 23 maintains a free state. Further, it is also possible to provide a means for maintaining the free state between the guided portion 23 and the rack 17 such that the guided portion 23 engages with the rack 17 when the hand is released after being pushed further strongly. .

  The stopper 21 and the column portion 13 may be moved only in the vertical direction so as not to rotate depending on the structure of the key and the key groove, or may be combined so as to be rotatable. Accordingly, the stopper 21 may be rotated in the left-right direction and retracted so as not to contact the lever 93 so that the currant 91 can be easily brought into the entire state. At this time, if the rack 17 is provided on the entire circumference of the column portion 13, the contact portion 22 of the stopper 21 is retracted without releasing the locking relationship between the locking portion 32 of the positioning portion 31 and the rack 17. Can be made.

Further, as the positioning portion, a resistor having elasticity such as packing is arranged between the aforementioned column portion 13 and the guided portion 23 so that the stopper 21 does not fall by its own weight due to the resistance. Also good. Even in this case, when a person operates the lever 93 to lift the lever 93, a force is applied to the stopper 21 to be pushed up by the lever 93, but this force is applied to the contact portion 22 at the tip of the stopper 21. Therefore, in the guided portion 23, a force acts backward on the column portion 13 at the upper end, and a force acts forward on the column 11 at the lower end. Therefore, these forces act as resistance of the force that raises the stopper 21, and the stopper 21 stops at that position and can stop the raising of the lever 93. Therefore, even if the rack 17 is not provided, the resistor between the column portion 13 and the guided portion 23 can be implemented as a positioning portion. In this case, the rack 17 and the locking portion 32 are omitted. It is also possible to do. Moreover, it is good also as a structure which provides a screw so that protrusion is possible from the outer side of the to-be-guided part 23, and presses the column part 13 with the front-end | tip of this screw, and performs positioning.
Even when the rack 17 and the locking portion 32 are not omitted, a resistor having elasticity such as packing is arranged between the column portion 13 and the guided portion 23 so that the column portion 13 and the covered portion 32 are covered. When sliding with the guide portion 23, a slight resistance may be applied.

  FIG. 5 shows another embodiment. In this example, a gear 41 is provided as the positioning portion 31. Specifically, the gear 41 that engages with the rack 17 of the pillar portion 13 is provided in the guided portion 23, the handle 43 is provided on the rotation shaft 42 of the gear 41, and the handle 43 is rotated to rotate the gear 41. Thus, the guided portion 23 moves up and down while meshing with the rack 17. At this time, by providing a resistor such as a packing that serves as a rotation resistance on the rotation shaft 42 or the handle 43, the stopper 21 stops at that position even when the hand is released from the handle 43.

FIG. 6 shows still another embodiment. In this example, a male screw 51 is provided in the column portion 13 of the support column 11, and a female screw 52 is provided in the guided portion 23. It is possible to move up and down while rotating. In this example, the upper and lower positions of the stopper 21 can be freely set by screwing of the screws, and the male screw 51 and the female screw 52 act as the positioning portion 31. When the contact portion 22 of the stopper 21 is not brought into contact with the lever 93, the contact portion 22 may be rotated to the side or rear so that the contact portion 22 is disengaged from the upper position of the lever 93.
As described above, the present invention can be implemented with various modifications within the scope of the claims, and the material can be selected and implemented as long as it has an appropriate rigidity such as synthetic resin or metal. be able to.
