[0002]
[Prior art]
Conventionally, a single lever faucet that adjusts the amount of discharged water based on the up-and-down rotation of the control lever and adjusts the temperature of the discharged water based on the left-right rotation is used as a kitchen faucet, bathroom faucet, toilet faucet, etc. Widely used.
This single lever faucet can be operated lightly, has a good operation feeling, and has the characteristics that the operation lever can be operated quickly and at once from the fully closed state to the fully open state.
[0003]
However, this feature, on the other hand, leads to a problem that it is not always easy to finely adjust the amount of water.
For example, despite the fact that a relatively small amount of water is sufficient, it is difficult to carry out the delicate operation of the control lever, so it is often the case that this is suddenly changed from the fully closed state to the fully opened state. .
In this case, a lot of precious water is washed away.
[0004]
Various countermeasures have been proposed for generating a click feeling when the operating lever reaches a predetermined position (setting position) during the operation from the fully closed state to the fully opened state.
In many cases, a click mechanism is provided between the lever shaft and the peripheral member.
[0005]
For example, a recess is formed in the lever shaft that moves integrally with the operation lever, and the ball is accommodated in the recess. The spring is set in the recess and urged in the protruding direction, while the lever shaft rotates left and right with the lever shaft. Click on the control lever by providing a recess on the inner peripheral surface of the rotation guide, and when the ball moves integrally with the lever shaft, the ball that has reached the position of the recess is partially inserted into the recess of the rotation guide. There has been proposed one that is temporarily stopped there with a feeling.
[0006]
On the other hand, FIG. 8 shows another example disclosed in Japanese Patent Laid-Open No. 2001-74152. This example is also an example in which a click mechanism is provided between the lever shaft and the peripheral member.
In this example, a click mechanism 204 is provided between the lever shaft 200 and the upper part of the housing 202 of the faucet body.
The click mechanism 204 includes an engagement recess 206 provided in the lever shaft 200, an engagement body 208 having an engagement protrusion engaged therewith, a spring 210 that biases the engagement body in the engagement direction, and a plug body. 212, and an engagement body 208, a spring 210, and a ring 214 that holds the plug body 212.
In this example, the lever shaft 200 rotates around the shaft 216 based on the vertical rotation operation of the operation lever, and when it reaches a predetermined position, the engagement convex portion of the engagement body 208 is provided on the lever shaft 200. The mating recess 206 is elastically engaged to generate a click feeling.

[0029]
In the case of the single lever faucet 10 of this example, when the operation lever 28 is rotated up and down, the lever shaft 64 rotates around the shaft 72, and accordingly, the movable valve body 46 is fixed by the drive unit 48. The upper surface of 42 is slid linearly in the left-right direction in FIG. 2 to adjust the amount of water.
Further, when the operation lever 28 is rotated left and right in a direction perpendicular to the paper surface in FIG. 2, the rotational motion is transmitted to the movable valve body 46 through the rotation guide 50 and the drive unit 48, whereby the movable valve body 46 is fixed. The temperature of water discharge is adjusted by rotating the surface 42 in a direction perpendicular to the paper surface.
[0030]
As shown in FIGS. 3 to 5, when the operation lever 28 is turned up and down (that is, the amount of water) between the rotation guide 50 and the drive unit 48, specifically, between the rotation guide 50 and the drive unit 48. A click mechanism 74 for generating a click feeling at a predetermined position during adjustment operation) is provided.
As shown in FIG. 5, the click mechanism 74 includes a first engagement body 76 and a second engagement body 78.
[0031]
As shown in FIG. 6, the first engaging body 76 is formed in a rectangular frame shape having a hollow portion 80 as a whole, and a convex engaging portion 82 is formed at the upper end thereof.
The first engagement body 76 is provided with a predetermined elasticity in the vertical direction in FIG. 5 based on the frame shape, that is, in the engagement direction of the convex engagement portion 82 with the engagement groove described later in the second engagement body 78. Has been.
[0032]
A recess 84 is formed in the upper surface of the drive unit 48.
The recess 84 accommodates the second engagement body 78 so as to be relatively movable in the water amount adjustment direction, that is, in the left-right direction in FIG. 3, and a fitting recess 86 is provided downward from the bottom surface of the recess 84. .
The first engaging body 76 is detachably inserted into the fitting recess 86 through the opening 88 opened at the bottom surface of the recess 84. Thus, in the inserted state, the convex engagement portion 82 at the upper end of the first engagement body 76 protrudes upward from the bottom surface of the recess 84 by a predetermined height.
[0033]
On the other hand, the second engagement body 78 is provided integrally with the rotation guide 50 so as to protrude downward from the lower surface of the rotation guide 50.
A plurality of engagement grooves (concave engagement portions) 90S, 90A, 90B, and 90F are formed on the lower surface of the second engagement body 78 along the moving direction of the drive unit 48, that is, the left-right direction in FIG. Has been.
A click feeling is generated by elastically engaging the convex engagement portion 82 of the first engagement body 76 with the engagement grooves 90S, 90A, 90B, 90F.
[0034]
Here, the engaging groove 90S is a part for engaging the convex engaging part 82 when the operation lever 28 is fully closed, and the engaging groove 90F is a part for engaging the convex engaging part 82 when the operating lever is fully opened. is there.
[0035]
On the other hand, of the intermediate engaging grooves 90A and 90B, the engaging groove 90A is a portion for engaging the convex engaging portion 82 when the operation lever 28 is slightly opened from the fully closed state, and the engaging groove 90B. Is a portion for engaging the convex engaging portion 82 when the operating lever 28 is further operated to the open side from that state.

As described above, the second engagement body 78 is accommodated in the recess 84 formed in the drive portion 48, and relative to the drive portion 48 in the left-right direction in FIG. Move on.
Specifically, the drive unit 48 linearly moves relative to the rotation guide 50 in the water amount adjustment direction by relatively moving the second engagement body 78 in the recess 84.
[0037]
FIG. 7 shows the operation of the single lever faucet with a click mechanism of this example.
(I) in FIG. 7 represents a state in which the operation lever 28 is fully closed. At this time, the convex engagement portion 82 of the first engagement body 76 is engaged with the engagement groove 90S of the second engagement body 78. It is in.
When the operation lever 28 is turned upward from the state in this state, the convex engagement portion 82 is disengaged from the engagement groove 90S of the second engagement body 78 while the first engagement body 76 is bent in the contraction direction. By the way, it engages with the engaging groove 90A that follows this (see FIG. 7 (II)).
[0038]
Based on the click feeling generated at that time, the faucet user can feel that the operation lever 28 has come to the first setting position.
Furthermore, when the operating lever 28 is turned upward in the figure from this state, the convex engaging portion 82 engaged with the engaging groove 90A is further engaged with the next engaging groove 90B. Therefore, a click feeling at the second stage is generated, and the operation lever 28 temporarily stops there.
Further, when the operating lever 28 is turned upward from that state, the convex engaging portion 82 engaged with the engaging groove 90B is engaged with the final engaging groove 90F while generating a click feeling (see FIG. 7 (III)), let the user know that the operating lever 28 has reached the final position.
[0039]
In this example, the click feeling is generated at two places on the way from the fully closed state to the fully opened state. Of course, only one place may be generated, or the click feeling is generated at three or more places. It can also be done.
[0040]
In the single lever faucet 10 of the present example as described above, the click mechanism 74 is provided between the rotation guide 50 of the lever shaft 64 and the drive portion 48 of the movable valve body 46, and thus various conventionally. There is no need to secure a space for attaching the click mechanism around the lever shaft 64 where the parts are assembled, or to attach the click mechanism to the lever shaft 64 so that the structure around the lever shaft 64 is not complicated. The mechanism 74 can be assembled around the single lever faucet 10, more specifically around the valve section.
[0041]
That is, in this example, the space between the rotation guide 50 and the drive portion 48 of the movable valve body 46 that has not been particularly used in the prior art is effectively utilized, and the click mechanism 74 is provided there. The click mechanism 74 can be incorporated therein without complicating the inside of the valve cartridge 40 having a complicated structure in particular, and without further increasing the size of the valve cartridge 40.
[0042]
In this example, the click mechanism 74 is provided between the rotation guide 50 and the drive unit 48 that linearly moves with respect to the rotation guide 50 when the operation lever 28 is rotated up and down, that is, when the water amount is adjusted. 74 can be operated smoothly and reliably.
Also in this example, the first engagement body 76 is formed in a hollow frame shape, and based on the frame shape, the elastic performance in the engagement direction between the convex engagement portion 82 and the engagement grooves 90S to 90F as the concave engagement portions. Therefore, a large resistance force is not generated when the convex engagement portion 82 is engaged with the engagement grooves 90S to 90F, and the elastic force of the first engagement body 76 is surely operated while gently operating the operation lever 28. A clear click feeling can be generated based on the performance.
[0043]
Further, since the click feeling is generated based on the elastic deformation of the first engagement body 76, the convex engagement portion 82 or the portion around the engagement grooves 90S to 90F is greatly worn while the click mechanism 74 is operated. Thus, it is possible to effectively prevent the click feeling from becoming weak or disappearing gradually.
[0044]
In this example, since the first engagement body 76 is detachably attached to the drive unit 48, when the click mechanism is not necessary, the first engagement body 76 can be simply removed from the drive unit 48 by simply clicking. A single lever faucet having no mechanism can be configured.
That is, it is possible to make common parts of the faucet having the click mechanism and the faucet not having the click mechanism.
[0045]
Further, in this example, a recess 84 is provided on the drive unit 48 side, and the second engagement body 78 provided in a protruding shape on the rotation guide 50 side is accommodated therein. Therefore, the rotation guide is assembled by assembling the click mechanism 74. 50 and the drive unit 48 are not particularly large, or the click mechanism 74 is protruded from the rotation guide 50 and the drive unit 48 to increase the size of the valve cartridge 40. While maintaining the appearance, it is possible to provide a click function.
[0046]
Further, the projecting second engagement body 78 relatively moves in the direction of adjusting the amount of water inside the recess 84, and at this time, the second engagement body 78 and the recess 84 constitute a linear motion guide portion. There is an advantage that a function of smoothly moving and guiding the rotation guide 50 in the water amount adjustment direction can be obtained.
[0047]
Although the embodiment of the present invention has been described in detail above, this is merely an example.
For example, it is possible in some cases to provide the second engagement body 78 on the drive unit 48 side and the first engagement body 76 on the rotation guide 50 side. Further, the second engagement body 78 is configured in a rectangular frame shape. It is also possible to give a bullet performance to the second engagement body 78 side.
In this example, the second engagement body 78 is provided integrally with the rotation guide 50. However, in some cases, the second engagement body 78 may be configured separately and attached to the rotation guide 50 so as to be detachable. The present invention can be configured in various forms without departing from the gist thereof.
