For example, in spite of the fact that a relatively small amount of water is sufficient, it is difficult to perform a delicate operation of the operation lever. .
In this case, precious water is wasted much.
[0004]
As a countermeasure, various proposals have been made so far that a click feeling is generated when the operation lever reaches a predetermined position (set position) during the operation from the fully closed state to the fully opened state.
Most of them provide a click mechanism between a lever shaft and a peripheral member.
[0005]
For example, a recess is formed in a lever shaft that moves integrally with the operation lever to accommodate a ball therein, and this is biased in the popping direction by a spring set in the recess, while the lever shaft that rotates left and right with the lever shaft. A concave is provided on the inner peripheral surface of the rotary guide, and when the ball moves integrally with the lever shaft, the ball that has reached the concave position is partially fitted into the concave of the rotary guide, and the operation lever is clicked. There has been proposed a device which is once stopped there with a feeling.
[0006]
On the other hand, FIG. 8 shows another example disclosed in JP-A-2001-74152, which is also an example in which a click mechanism is provided between a lever shaft and peripheral members.
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 engaging recess 206 provided on the lever shaft 200, an engaging body 208 having an engaging protrusion engaging with the engaging recess 206, a spring 210 for urging the engaging body 208 in the engaging direction, and a plug body. And a ring 214 for holding the engaging body 208, the spring 210 and the plug 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 the lever shaft 200 reaches a predetermined position, the engaging protrusion of the engaging body 208 is provided on the lever shaft 200. The elastic member engages with the concave portion 206 to generate a click feeling.

FIG. 7 shows the operation of the single lever faucet with a click mechanism of this example.
FIG. 7 (I) shows a state in which the operation lever 28 is fully closed. At this time, a state in which 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 rotated upward in the drawing from this state, the convex engagement portion 82 is disengaged from the engagement groove 90S of the second engagement body 78 while bending the first engagement body 76 in the contracting direction. By the way, it fits into and engages with the following engaging groove 90A (see FIG. 7 (II)).
[0040]
Based on the click feeling generated at that time, the faucet user can feel that the operation lever 28 has come to the first set position.
Furthermore, when the operation lever 28 is rotated upward in the drawing from this state, the convex engagement portion 82 that has been engaged with the engagement groove 90A is further engaged with the next engagement groove 90B. Then, a second-stage click feeling is generated, and the operation lever 28 temporarily stops there.
When the operating lever 28 is further turned upward from this state, the convex engaging portion 82 engaged with the engaging groove 90B engages with the final-stage engaging groove 90F while generating a click feeling (FIG. 7 (III)), the user is notified that the operation lever 28 has reached the final position.
[0041]
In this example, the click sensation is generated at two places in the course of the transition from the fully closed state to the fully open state. However, it is needless to say that only one place may be generated, or a click sensation may be generated at three or more places. You can do something like that.
[0042]
In the single lever faucet 10 of the present embodiment as described above, the click mechanism 74 is provided between the rotation guide 50 of the lever shaft 64 and the drive unit 48 of the movable valve body 46, and therefore, various conventional devices are used. A space for mounting the click mechanism is secured around the lever shaft 64 to which the parts are assembled, or the structure around the lever shaft 64 is not complicated by attaching the click mechanism there, and the click can be easily performed. The mechanism 74 can be assembled around the single lever faucet 10, specifically around the valve.
[0043]
That is, in this example, since the space between the rotation guide 50 and the drive unit 48 of the movable valve body 46, which is not particularly used in the past, is effectively used, and the click mechanism 74 is provided there, various conventional parts are incorporated. 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 increasing the size of the valve cartridge 40.
[0044]
In this example, the click mechanism 74 is provided between the drive unit 48 that linearly moves with respect to the rotation guide 50 and the rotation guide 50 when the operation lever 28 is vertically turned, that is, when the amount of water is adjusted. 74 can be operated smoothly and reliably.
In this example, the first engagement body 76 is formed in a hollow frame shape, and the elastic performance is set in the engagement direction between the convex engagement portion 82 and the engagement grooves 90S to 90F as the concave engagement portion based on the frame shape. Is provided, a large resistance force is not generated when the convex engaging portion 82 is engaged with the engaging grooves 90S to 90F, and the elastic force of the first engaging body 76 is reliably achieved while operating the operation lever 28 lightly. A clear click feeling can be generated based on the performance.
[0045]
In addition, since the click feeling is generated based on the elastic deformation of the first engagement body 76, the portion around the convex engagement portion 82 or the engagement grooves 90S to 90F is greatly worn while the click mechanism 74 operates. Then, it is possible to effectively prevent the click feeling from gradually weakening or disappearing.
[0046]
Further, in this example, since the first engagement body 76 is detachably attached to the drive unit 48, when the click mechanism is unnecessary, the first engagement body 76 can be easily removed by simply removing the first engagement body 76 from the drive unit 48. A single lever faucet having no mechanism can be configured.
That is, it is possible to use common parts for a faucet having a click mechanism and a faucet without a click mechanism.
[0047]
Further, in this example, the concave portion 84 is provided on the drive section 48 side, and the second engaging body 78 provided in the protruding shape on the rotary guide 50 side is accommodated therein. In particular, the size of the valve cartridge 40 does not increase, and the click mechanism 74 protrudes from the rotation guide 50 and the drive unit 48 to the outside. While maintaining the appearance of, a click function can be provided there.
[0048]
Further, since the protruding second engagement body 78 relatively moves in the water amount adjusting direction inside the recess 84, and at this time, the second engagement body 78 and the recess 84 constitute a linear motion guide section, the driving section 48 is used. There is an advantage that a function of smoothly moving and guiding the rotation guide 50 in the water volume adjustment direction can also be obtained.
[0049]
The embodiment of the present invention has been described in detail above, but 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 to provide the first engagement body 76 on the rotation guide 50 side. Further, the second engagement body 78 may be formed in a rectangular frame shape. It is also possible to provide the second engagement body 78 with the elastic performance.
Further, 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 separately formed and detachably attached to the rotation guide 50. It can be configured in a form in which various changes are made without departing from the gist thereof.
