Description

The present invention is a water discharge amount adjusting device provided on the operation lever side of a mixing faucet fixture, and is a single lever type that can be provided on a newly manufactured faucet fixture and can be attached to or replaced with an existing faucet fixture. The present invention relates to a water discharge amount adjusting device for a mixing faucet.

Conventionally, there has been no idea of providing a means for adjusting the amount of water discharged from the single lever type mixing faucet directly on the operation lever side.

Japanese Patent Application Laid-Open No. 2003-184141 JP-A-2007-063859

First, Patent Document 1 operates by fixing a base with a water-saving stopper attached to the upper end of the peripheral portion of the cylindrical main body of a single-lever mixing faucet with a screw and moving the water-saving stopper onto the base. When the lever is moved, the operating lever stops when the lower end of the operating lever comes into contact with the water saving stopper, thereby adjusting the amount of water discharged.
However, the problem with this configuration is that, as described in the claim, there are only two stages of water discharge amount, maximum flow rate and medium flow rate, and the bigger problem is that the lower end surface of the peripheral portion of the operating lever is not flat. That is, the gap between the upper end surface of the peripheral portion of the cylindrical body and the lower end surface of the operation lever is not uniform, and half of the lower end surface on the operation lever side maintains a uniform gap with the upper end surface of the main body, but the rest. Half is an inclined surface for rotating the operating lever up and down.
Therefore, even if the water-saving stopper is set at a position where the amount of water is medium, if the operating lever of the hot water mixing faucet is swiveled to the left or right to control the temperature, the distance between the lower end surface of the operating lever and the water-saving stopper will change, and the water will be discharged. Since the amount of water is not stable, there is no point in setting it.
Therefore, it is obvious that the invention of Document 1 has not been confirmed, and it is merely a desk theory and no effect can be obtained.

Next, in Document 2, the movement width of the operating lever is adjusted by a method different from that in Document 1, and a contact portion whose height is adjusted by a pillar portion and a guided portion is provided at the lower end of the cylindrical main body. The height of this contact part can be adjusted by operating the operation part at the bottom of the back, and the amount of water discharged can be maximized by turning the contact part and shifting it from the position of the operation lever, and also returning it to the original amount of water. You can also do it.
However, in order to perform this operation, the contact portion must first be swiveled and moved from the flow rate restricted state, the operation lever must be raised to maximize the amount of water, the operation lever must be lowered, and then the contact portion must be returned to its original position. Because it doesn't become, it takes 4 steps.

In addition, the overall structure is extremely complicated, especially the structure of the positioning part can be drawn small in the figure, but it will be larger than the figure when actually produced, and the distance between the faucet fixture and the rise of the sink is usually wide. Since there are only about three fingers, there is a guided part and a positioning part, so it is too narrow to operate the positioning part.
Further, according to the description in paragraph [0016] of the specification, the size of the contact portion is "the lever can come into contact with the contact portion within the rotation range of the lever", so that the rotation angle of the lever is general. When it is a fan shape that can handle this lever at least 90 degrees, it is disproportionately large and ugly with respect to the size of the mixing faucet.
Furthermore, since the conventional mixing faucet fixture has a cylindrical body directly attached to the sink, it looks good and the only part that is difficult to clean is the peripheral part of the base between the sink and the body, and the quantity is minimal. However, according to the embodiment, it is difficult to clean because the base and the support column increase the number of extra steps, the number of places where dirt accumulates increases to two or more, and the space between the base and the rise is narrow.
Therefore, Document 2 also has a large number of parts, and the manufacturing cost is high and expensive due to the labor of assembling work due to the complicated structure.
Therefore, the present application provides an inexpensive single-lever type mixing faucet water discharge amount adjusting device, which is provided on an operation lever, is small, has a small number of components, has a small number of operation procedures, and has a good appearance.

In the present invention, the distance between the holding portion provided on the operating lever side of the mixing faucet consisting of the substrate, the faucet and the operating lever, and the distance between the holding portion and the outer surface of the substrate can be appropriately set by a screw or the like. A sliding body is interposed between the holding portion and the screw or the like in order to provide the means and to release the setting of the interval adjusting means.

The present invention has the following effects due to the above configuration.
1. 1. Since the water discharge amount adjusting device provided directly on the operation lever can set the vertical rotation angle of the operation lever steplessly by using the spiral of the screw, the water discharge amount can be finely and easily adjusted.
2. 2. The amount of water discharged is adjusted by the distance between the tip of the adjusting screw provided on the operating lever and the outer peripheral surface of the cylindrical substrate. No matter where the operating lever is stopped, the distance between the tip of the screw and the cylindrical substrate does not change, so the set amount of water discharge can be stably obtained. Therefore, the operating lever can be swiveled horizontally. Since the adjustment screw can be turned in this state, it is easy to set the amount of water discharged.
3. 3. Even if the water discharge amount is set, you can cancel the setting and change it to the maximum water discharge amount with a single operation, and it is easy and convenient because you can return to the original set water discharge amount by the force of a magnet etc. just by stopping the water discharge. be .

It is a side view which shows the state at the time of water discharge of Example 2. FIG. Both C and D are views taken along the line aa of FIG.

A form for carrying out the invention

The water discharge amount adjusting device for the single lever type mixing faucet of the present invention is not limited to the examples described below, and is within the scope of the technical idea of the present invention, that is, a shape and a size capable of exhibiting the same action and effect. It can be changed as appropriate within the range of.

Earlier, the single-lever type mixing faucet fixture shown in the drawing is an example of a commonly used fixture, and most of the fixtures have the same shape, and the diameter of the substrate is about 45 mm and about 55 mm. Further, in the illustration, the vertical rotation angle of the operation lever will be described with the fully open state as 24 degrees for convenience of explanation.

The first embodiment shows the basic configuration of the present invention.
First, in FIG. 1, an operation lever 3 that enables vertical rotation and left / right rotation is arranged at the uppermost portion of the cylindrical substrate 1 of the mixing faucet, and is located on the opposite side of the sink of the operation lever 3. A holding portion 5 of the water discharge amount adjusting device 4 is formed, and the holding portion 5 is provided with an adjusting screw 6 whose tip is a contact portion 7.

As shown in FIG. 1, the method and operation of the first embodiment is that when the vertical rotation angle of the operating lever 3 is 0 degrees, the opening angle between the holding portion 5 and the outer peripheral surface of the substrate 1 is 24 degrees. At this time, the water discharge has stopped.
Next, in FIG. 2A, when the operating lever 3 is rotated upward to the limit and the rotation angle is set to 24 degrees, the opening angle between the holding portion 5 and the outer peripheral surface of the substrate 1 becomes 0 degrees. The amount of water discharged at that time is the maximum.
Next, in Fig. B, when adjusting the momentum of water discharge for water saving or other reasons, the adjusting screw 6 is turned to the left or right while the contact portion 7 of the adjusting screw 6 is in contact with the outer peripheral surface of the substrate 1. The distance between the holding portion 5 and the outer peripheral surface of the substrate 1 may be appropriately adjusted.
Since the rotation angle of the operating lever is set to 12 degrees in this figure, the amount of water discharged is about half of the maximum amount of water discharged.
When turning the adjusting screw 6, turn it while checking the amount of water discharged, and stop turning when the required amount of water discharged is reached, the amount of water discharged is set at that time, and the same amount of water discharged is always obtained thereafter.
Further, the adjusting screw 6 may be a ratchet type or the like that can rotate instead of the screw.

Next, the second embodiment will be described in detail with reference to FIGS. 3, 4, and 5.
First, FIG. 1 is a side view of this embodiment, in which the rotation angle of the operating lever 11 is 24 degrees, and the maximum water discharge amount is shown.
The basic configuration of this embodiment is the same as that of the first embodiment, but the difference from the first embodiment is that a sliding body 15 that can move up and down is interposed in the holding portion 12, and an adjusting screw 18 is provided therein.
The sliding body 15 is pulled up to the upper part of the guide groove 13 by a magnet, and when the sliding body 15 is lowered, the adjusting screw 18 is manually pushed down.
Further, the method of pulling up the sliding body may be a spring or the like instead of the magnet.

Next, FIG. C of FIG. 4 is a view taken along the line aa of FIG. 18 is provided, and convex portions 17 and 17 protruding to the left and right are further formed at the lower end.
A vertically long recess into which the sliding body 15 is inserted is formed in the center of the holding portion 12, and guide grooves 13 and 13 on which the sliding body 15 can slide the required length are provided facing each other on the upper portions of both side surfaces of the recess. Fixed recesses 14a and 14a for inserting the convex portions 17 and 17 are formed in the lower portions of both side surfaces.
Then, the shaft portions 16 and 16 formed on the sliding body 15 are fitted to the upper part in the guide grooves 13 and 13 to form a water discharge amount adjusting device.

Next, FIG. D shows a state in which the sliding body 15 in FIG. C is moved downward, the shaft portions 16 and 16 move to the lower end in the guide grooves 13 and 13, and the convex portions 17 and 17 move in the same manner. Then, it pops out under the holding portion 12 and comes off from the fixing recesses 14a and 14a, that is, the fixing recesses 14a and the convex portion 13 are the fixing mechanism of the sliding body 15, and the sliding body 15 is hung by the shaft portion 16. It indicates that the fixation has been released.

Next, FIG. 5 is a partial cross-sectional view showing a state in which the amount of water discharged in this embodiment is adjusted, and the sliding body 15 provided with the adjusting screw 18 moves up and down as described above.
According to Fig. E, the operation lever 11 is rotated 12 degrees to set the water discharge amount to about half of the maximum water discharge amount, but in order to temporarily change the water discharge amount to the maximum, the sliding body 15 is first moved downward. The convex portion 17 is also moved and shows a state of being separated from the lower end of the holding portion 12.
Subsequently, in FIG. F, the operation lever 11 is rotated to the maximum water discharge amount of 24 degrees in a state where the contact portion 19 at the tip of the adjusting screw is in contact with the outer peripheral surface of the substrate 1, and the contact portion 7 is rotated. Since it is in contact with the outer peripheral surface of the substrate, the sliding body 15 rotates around the shaft portion 16 and retracts backward.
At this time, as shown in the enlarged view of FIG. F, the upper angle of the sliding body is inserted into the fixing recess 14b formed in the holding portion 12, and the sliding body is in a fixed state. It does not rise to.

Subsequently, in order to release the maximum water discharge amount and return it to the original set water amount, as shown in the above figure E, magnets 20 are provided on both the holding portion 12 side and the sliding body 15 side, and are set so as to attract each other. Therefore, even if the sliding body 15 is moved downward, it is always pulled upward, and when the operating lever 11 is returned to the 0 degree position, that is, when the water discharge is stopped, the holding body 12 and the outer peripheral surface of the substrate 1 are contacted. The angle of is widened from 0 degrees to 24 degrees, and the sliding body 15 automatically fits in the recess of the holding body 12 and is pulled up by the magnetic force.
At this time, when the operation lever 11 is rotated upward to stop the water discharge, the sliding body 15 is stopped due to the inertia of the weight of the sliding body and the adjusting screw combined, and the holding body 12 is placed there. The sliding body fits into the vertically long recess approaching from the side, and at the same time, it also comes off from the fixed recess 14b and is pulled upward by the magnetic force to return to the original set water discharge amount.

Next, Example 3 will be described in detail with reference to FIG.
First, FIG. 6 is a partial cross-sectional view of the present embodiment, which is basically the same as that of the second embodiment, except that in the second embodiment, the adjusting screw is pushed with a finger to move the sliding body downward. In this embodiment, the sliding body is pushed down directly from above the operating lever.
As shown in FIG. G, a straight rod-shaped sliding body 25 having an adjusting screw 29 at the bottom is arranged in the guide recess 23 formed in the holding portion 22, and a fixed recess 24b is formed at the upper end of the guide recess 23. is doing.
In this figure, since the operating lever 21 is rotated 5 degrees, the opening angle between the holding portion 22 and the outer peripheral surface of the substrate 1 is set to 19 degrees.
Next, in FIG. H, in order to rotate the operating lever 21 from the state shown in FIG. G to the maximum water discharge amount of 24 degrees, the push portion 26 at the upper end of the sliding body 25 is pushed into the fixed recess 24b along the arrow a. In this state, the opening angle between the holding portion 22 and the outer peripheral surface of the substrate 1 is 0 degrees, but the lower portion of the sliding body 25 is released from the fixing and the shaft portion 27 is released as in the above-described second embodiment. Since the 26 is fitted into the fixed recess 24b, the sliding body 25 is in a fixed state.
Further, when the operation lever 21 is rotated to 0 degrees, that is, when the water discharge is stopped, the next time the operation lever is rotated, the operation lever 21 is stopped at the original position rotated by 5 degrees.

Next, Example 4 will be described in detail with reference to FIG. 7.
In this embodiment, as shown in FIG. 7, the adjusting screw 33a is directly provided on the holding portion 32 formed on the operating lever 31.
First, FIG. I shows a state in which the rotation angle of the operation lever 31 is set to 0 degrees and water discharge is stopped.
Next, FIG. J shows a state in which the adjusting screw 33a is adjusted so that the operating lever 31 can be rotated up to 12 degrees. It shows that the amount of water discharged is about half.
At this time, the adjusting screw 33a collides with the mounting base 35 formed on the upper part of the base 1 and for mounting the operation lever 31, so a hollow portion 36 must be provided in advance on a part of the mounting base 35. Therefore, it is not possible to attach it to an existing mixing faucet fixture, and the substrate 1 must be newly manufactured.
Further, in the present embodiment, as a method of temporarily canceling the setting, it is preferable to provide a mechanism for moving the adjusting screw 33a to the position of the adjusting screw 33b as shown in the figure.

Next, Example 5 will be described in detail with reference to FIG.
This embodiment is different from the embodiments 1 to 4 described so far, and the water discharge amount adjusting device is separated from the operating lever, and is mounted on the upper surface of the operating lever of the existing mixing faucet. It is intended to be worn.
FIG. 8 is a side view of this embodiment, and as shown in FIG. K, the holding portion 45, the sliding body 46, and the adjusting screw 49 are the same as those in the above-described second embodiment, and have exactly the same operations and effects. Therefore, the holding portion 45 is provided with a mounting portion 43.
In the mounting method of this embodiment, the upper surface of most of the operating levers has a gently curved surface, but the degree of the curved surface is unspecified, so that the water discharge amount adjusting device of this embodiment can be stably mounted. A mounting material 44 is interposed between the operating lever 41 and the mounting portion 43.
In order to match the mounting material 44 with various unspecified curved surfaces of the operating lever 41, according to the silicon resin that softens at a hot water temperature of 70 to 80 degrees, the curved surface of the operating lever 41 and the mounting portion 43 If stability is obtained and the fixing is performed with an adhesive or a band, the same effect as in Example 2 can be obtained.
Next, FIG. L shows the state of the maximum water discharge amount by rotating the operation lever 41 by 24 degrees.

The present invention is a water discharge amount adjusting device provided on the operation lever side of a single-lever type mixing faucet fixture, which is provided on a newly manufactured faucet fixture, attached to an existing faucet fixture, or replaced with a lever. The present invention relates to a water discharge amount adjusting device for a single-lever type mixing faucet.

Conventionally, there has been no idea that all the configurations of the means for adjusting the amount of water discharged from the single lever type mixing faucet are directly provided on the operation lever side.

Japanese Patent Application Laid-Open No. 2003-184141 JP-A-2007-063859

First, in Patent Document 1, a base having a water-saving stopper attached to it is fixed to the upper end of the peripheral portion of a cylindrical body of a single-lever type mixing faucet with a screw, and the water-saving stopper is rotated and moved onto the base. When the lever is lowered, the lever stops when the lower end of the lever comes into contact with the water saving stopper to adjust the amount of water discharged.
However, the problem with this configuration is that, as described in the claim, there are only two stages of water discharge amount, maximum flow rate and medium flow rate, and the position of the water saving stopper is provided separately on the left and right sides of the water supply side and the hot water supply side. That is, the lever swivels from the water side end to the maximum temperature side end, but there is no water saving stopper at the position corresponding to the intermediate temperature, and the water saving effect can be obtained only at either water or the maximum temperature. ..
In addition, Document 1 has a structure in which water flows out when the lever is lowered, but it has been changed to the reverse form in which water flows out when the lever is raised, following the Great Hanshin-Awaji Earthquake. Since the same theory holds if it is rotated half a turn, the above problem exists in any case.
Therefore, it is obvious that the invention has not been confirmed in Document 1, and it is merely a desk theory.

Next, Document 2 adjusts the vertical movement width of the operating lever by a method different from that of Document 1, and a stopper 21 is provided at the upper end of the guided portion 23 that enables vertical movement with respect to the pillar portion 13. The height of this stopper 21 can be adjusted by the operation part at the bottom of the back, and the amount of water discharged can be maximized by turning the stopper 21 and removing it from the lever 93, and returning the stopper to return to the original amount of water. There is.
However, to give an example, when adjusting the amount of water temporarily when the maximum amount of water is desired without waiting for the amount of water to reach a small amount in winter, first swivel the stopper 21 from the state of a small amount of water and move the lever. To remove the lever 93 from the top of the 93 and then raise the lever 93 to maximize the amount of water, and to return to the original small amount of water, the lever 93 must be lowered once, the stopper 21 must be returned to the top of the lever, and the lever 93 must be raised again. It doesn't become.
This operation involves moving the ▲ 1 ▼ stopper, raising the ▲ 2 ▼ lever to the maximum amount of water, then lowering the ▲ 3 ▼ lever, returning the ▲ 4 ▼ stopper, and raising the ▲ 5 ▼ lever to the stopper. In addition to five times, you have to release the stopper and lever each time.

Further, according to the description in paragraph [0016] of the specification, the size of the contact portion is "the lever can come into contact with the contact portion within the rotation range of the lever", so that the rotation angle of the lever is general. If the fan shape is at least 90 ° or more and can accommodate this lever, it will be disproportionately large and ugly with respect to the size of the mixing faucet, and the tip edge 24 will be concentric with the rotation of the lever 93. There is a description that it does not have to be a shape, but the amount of water is not constant unless it is concentric.
Therefore, Document 2 also has a large number of parts, and the manufacturing cost is high and expensive due to the labor of assembling work due to the complicated structure.
Therefore, the present application provides an inexpensive single-lever type mixing faucet water discharge amount adjusting device, which is provided on an operation lever, is small, has a small number of components, has a small number of operation procedures, and has a good appearance.

In the present invention, a holding portion provided on the operating lever side of a mixing faucet consisting of a substrate, a faucet, and an operating lever, an adjustment of the water discharge amount, and a setting of the adjusted water discharge amount are set on the outer surface of the substrate and the holding portion. The holding unit or the interval adjusting means is provided with an interval adjusting means for adjusting the interval and a setting canceling mechanism for temporarily canceling the setting of the water discharge amount by the interval adjusting means.

In the present invention, since the increase / decrease in the amount of water discharged is proportional to the vertical rotation width of the operating lever, the rotation width is adjusted by the interval adjusting means for adjusting the distance between the holding portion provided on the operating lever and the outer surface of the substrate. Since the amount of water discharged is increased or decreased and set, the effects described below are obtained.
1. 1. According to claim 1, the amount of water discharged can be adjusted and set only by turning the adjusting screw provided on the operation lever, and the amount of water discharged once set can always be the same as the amount of water discharged unless the setting is changed.
2. 2. According to claim 3, even if the water discharge amount is set, the setting release mechanism can be canceled to the maximum water discharge amount by one operation, and the water discharge amount can be stopped once to immediately return to the original state. It is convenient because it can be returned to the set amount of water.

It is a side view of Example 1 of this invention. Both A and B are side views showing the state at the time of water discharge in FIG. 1. It is a side view which shows the state at the time of water discharge of Example 2. FIG. Both C and D are views taken along the line aa of FIG. Both E and F are partial cross-sectional views showing a state at the time of water discharge in FIG. Both G and H are partial cross-sectional views showing a state at the time of water discharge in Example 3. Both I and J are side views showing the state at the time of water discharge of Example 4. Both K and L are side views of Example 5.

A form for carrying out the invention

The water discharge amount adjusting device for the single lever type mixing faucet of the present invention is not limited to the examples described below, and is within the scope of the technical idea of the present invention, that is, a shape and a size capable of exhibiting the same action and effect. It can be changed as appropriate within the range of.

Earlier, the single-lever type mixing faucet fixture shown in the drawing is an example of a commonly used fixture, most of the fixtures have the same shape, and the diameter of the substrate is about 45 mm and about 55 mm. In the figure, for convenience of explanation, the vertical rotation angle of the operation lever is set to 0 ° as the water discharge stop state, and the maximum water discharge amount is described when the operation lever is rotated upward by 24 °.

First, the first embodiment will be described in detail with reference to FIGS. 1 and 2.
The present embodiment shows the basic configuration of the present invention. FIG. 1 shows an operating lever 3 that can rotate up and down and turn left and right at the uppermost portion of the cylindrical substrate 1 of the mixing faucet. The holding portion 5 of the spacing adjusting means 4 is formed on the opposite side of the sink of the operating lever 3, and the holding portion 5 is provided with an adjusting screw 6 having the tip end as the abutting portion 7.

As shown in FIG. 1, the usage and operation of this embodiment are such that when the upward rotation angle of the operating lever 3 is 0 °, the opening angle between the holding portion 5 and the outer peripheral surface of the substrate 1 is 24 °. The water discharge at this time has stopped.
Next, in FIG. 2A, when the operating lever 3 is rotated upward to the limit and the rotation angle is set to 24 °, the opening angle between the holding portion 5 and the outer peripheral surface of the substrate 1 becomes 0 °. The amount of water discharged at that time is the maximum.
Next, in Fig. B, when adjusting the amount of water discharged for water saving or other reasons, turn the adjusting screw 6 in either the left or right direction while bringing the contact portion 7 of the adjusting screw 6 into contact with the outer peripheral surface of the substrate 1. , The distance between the holding portion 5 and the outer peripheral surface of the substrate 1 may be appropriately adjusted to the amount of water.
When turning the adjusting screw 6, the adjusting screw 6 is turned while checking the amount of water discharged, and if it is stopped when the required amount of water discharged is reached, the amount of water discharged is set at that time, and the same amount of water discharged is always obtained thereafter.
Since the rotation angle of the operating lever 3 is 12 ° in FIG. B, the amount of water discharged at this time is about half of the maximum amount of water discharged.
Here, even if the operating lever 3 is swiveled to the left or right to adjust the hot water temperature, the center line of the cylindrical substrate 1 and the swiveling core to the left and right of the operating lever 3 are equal, so at what temperature the operating lever 3 is swiveled. Even if it is stopped at the position, the distance between the contact portion 7 at the tip of the adjusting screw and the outer peripheral surface of the cylindrical substrate 1 does not change, so that the set water discharge amount can always be stably obtained even if the hot water temperature is changed.
Further, from the above, since the adjusting screw 6 is turned by pinching it with a fingertip, it is easy to turn the adjusting screw 6 by turning the operation lever to either the left or right end.

Next, the second embodiment will be described in detail with reference to FIGS. 3, 4, and 5.
First, FIG. 3 is a side view of this embodiment, and since the rotation angle of the operating lever 11 is 24 °, the maximum amount of water discharged is shown.
The basic configuration of this embodiment is the same as that of the first embodiment, but the difference from the first embodiment is that a sliding body 15 that can move up and down is interposed in the holding portion 12, and an adjusting screw 18 is provided therein.
The sliding body 15 is pulled up to the upper part of the guide groove 13 by a magnet, and when the sliding body 15 is lowered, the adjusting screw 18 is pushed down by the fingertip.

Next, FIG. C of FIG. 4 is a view taken along the line aa of FIG. 18 is provided, and convex portions 17 and 17 protruding to the left and right are further formed at the lower end.
A vertically long recess into which the sliding body 15 is inserted is formed in the center of the holding portion 12, and guide grooves 13 and 13 on which the sliding body 15 can slide the required length are provided facing each other on the upper portions of both side surfaces of the recess. Fixing recesses 14a and 14a for inserting the convex portions 17 and 17 are formed in the lower portions of the both side surfaces.
Then, the shaft portions 16 and 16 formed on the sliding body 15 are fitted to the upper portion in the guide grooves 13 and 13.

Next, FIG. D shows a state in which the sliding body 15 in FIG. C is moved downward, the shaft portions 16 and 16 move to the lower end in the guide grooves 13 and 13, and the convex portions 17 and 17 move in the same manner. Then, it is detached from the fixing recesses 14a and 14a in a state of protruding under the holding portion 12.
That is, since the fixed concave portion 14a and the convex portion 13 are a setting canceling mechanism for fixing the setting of the water discharge amount and releasing the setting, in FIG. D, the sliding body 15 is in a hanging state by the shaft portion 16 and the water discharge amount is discharged. Indicates that the setting of is canceled.

Next, FIG. 5 is a partial cross-sectional view showing a state in which the amount of water discharged in this embodiment is adjusted, and the sliding body 15 provided with the adjusting screw 18 moves up and down as described above.
In Fig. E, the operating lever 11 is rotated by 12 ° to set the amount of water discharged to about half of the maximum amount of water discharged, and the sliding body 15 is moved downward in order to temporarily change the amount of water discharged to the maximum amount. It shows a state in which the convex portion 17 has moved and is also detached from the lower end of the holding portion 12.
Here, the magnet 20 is provided on the holding portion 12 and the sliding body 15, but since the sliding body 15 is moving downward, a deviation occurs between the holding portion 12 and the magnet on the holding portion side 12 side, and the displacement causes sliding. A magnetic force is generated in the direction of pulling up the moving body 15.
Subsequently, in FIG. F, the operation lever 11 is rotated to the maximum water discharge amount of 24 ° in a state where the contact portion 19 at the tip of the adjusting screw is in contact with the outer peripheral surface of the substrate 1, and at this time, the contact portion 7 is the substrate. Since it is in contact with the outer peripheral surface of the above, the sliding body 15 shows a state in which it rotates around the shaft portion 16 and retracts backward.
At this time, as shown in the enlarged view of FIG. F, the upper angle of the sliding body is fitted into the fixing recess 14b formed in the holding portion 12 to be in a fixed state, so that the sliding body 15 has a magnetic force that pulls it upward by the magnet. Even if you work, it will not rise.
Further, the method of pulling up the sliding body may be a spring or the like instead of the magnet.
Then, when this setting is canceled and the maximum amount of water is discharged, the sliding body can be pushed down by the fingertip by extending the finger at the same time as the rotation of the operation lever.

Subsequently, in order to release the maximum water discharge amount and return it to the original set water amount, as shown in FIG. When the position is returned to the 0 ° position, that is, when the water discharge is stopped, the angle between the holding body 12 and the outer peripheral surface of the substrate 1 expands from 0 ° to 24 °, and the sliding body 15 is accommodated in the recess of the holding body 12 by its own weight and a magnet. At the same time, since it also comes off from the upper fixed recess 14b, it is pulled up by the magnetic force and rises, returning to the originally set amount of water.

Next, Example 3 will be described in detail with reference to FIG.
First, FIG. 6 is a partial cross-sectional view of the present embodiment, and the basics are the same as those of the second embodiment. In the embodiment, the sliding body can be pushed down directly from above the operating lever.
As shown in FIG. G, a straight rod-shaped sliding body 25 having an adjusting screw 29 at the bottom is arranged in the guide recess 23 formed in the holding portion 22, and a fixed recess 24b is formed at the upper end of the guide recess 23. is doing.
In this figure, since the operating lever 21 is rotated by 5 °, the opening angle between the holding portion 22 and the outer peripheral surface of the substrate 1 is set to 19 °.
Next, in FIG. H, in order to rotate the operating lever 21 from the state shown in FIG. G to the maximum water discharge amount of 24 °, the push portion 26 at the upper end of the sliding body 25 is pushed into the fixed recess 24b along the arrow a. The opening angle between the holding portion 22 and the outer peripheral surface of the substrate 1 is 0 °, but the lower portion of the sliding body 25 is released from the fixing and the shaft portion 27 is released as in the second embodiment. At the same time, the push portion 26 fits into the fixed recess 24b, and the sliding body 25 does not rise.
Further, if the operation lever 21 is returned to 0 °, that is, the water discharge is stopped, then when the operation lever is rotated upward for water discharge, the original set water amount of 5 ° is restored.

Next, Example 4 will be described in detail with reference to FIG. 7.
In this embodiment, as shown in FIG. 7, a direct adjusting screw 33a is provided on the holding portion 32 formed on the operating lever 31.
First, FIG. I shows a state in which the rotation angle of the operation lever 31 is set to 0 ° and water discharge is stopped.
Next, FIG. J shows a state in which the adjusting screw 33a is adjusted so that the operating lever 31 can be rotated up to 12 °. It shows that the amount of water discharged is about half.
At this time, the adjusting screw 33a collides with the mounting base 35 formed on the upper part of the base 1 and for mounting the operation lever 31, so a hollow portion 36 must be provided in advance on a part of the mounting base 35. Therefore, it is not possible to attach it to an existing mixing faucet fixture, and the substrate 1 must be newly manufactured.
Further, in the present embodiment, as a method of temporarily canceling the setting, it is preferable to provide a mechanism for moving the adjusting screw 33a to the position of the adjusting screw 33b as shown in the figure.

Next, Example 5 will be described in detail with reference to FIG.
This embodiment is different from the four embodiments described so far, and the water discharge amount adjusting device of the single-lever type mixing faucet is separated from the operation lever, and the existing single-lever type mixing is performed. The purpose is to attach it to the upper surface of the operation lever of the faucet.
FIG. 8 is a side view of the present embodiment, and as shown in FIG. K, the holding portion 45, the sliding body 46, and the adjusting screw 49 have the same operations and effects as those of the above-described second embodiment, and the holding portion 45 has the same function and effect. The attachment unit 43 is continuously installed in the.
In the mounting method of this embodiment, the upper surface of most of the operating levers has a gently curved surface, but the degree and shape of the curved surface are unspecified, and the amount of water discharged from the single lever type mixing faucet of this embodiment. In order to obtain stable mounting of the adjusting device, a mounting material 44 is interposed between the operating lever 41 and the mounting portion 43.
In order to match the attachment material 44 with various unspecified curved surfaces of the operating lever 41, a silicon resin plate or the like that softens at a temperature of 70 to 80 degrees can be used to attach the attachment material 44 to the unspecified curved surface of the operating lever 41. It can be used in the same manner as in Example 2 if it is in close contact with the portion 43 to obtain stability and is fixed in a composite manner with an adhesive or a band.
Next, FIG. L shows the state of the maximum water discharge amount by rotating the operation lever 41 upward by 24 °.
