DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single lever type faucet click mechanism.

[0002]

2. Description of the Related Art Conventionally, in a hot and cold water mixing faucet attached to a washroom, a kitchen, a bathroom, or the like, a valve operating shaft linked to a valve disposed on a faucet body is tiltably and rotatably mounted. There was a single lever type in which a lever handle was connected to the valve body operation shaft, and the opening and closing amount of the valve was adjusted by operating the lever handle to adjust the flow rate and the water discharge temperature.

[0003] That is, a fixed disk is disposed in the faucet body, and a movable disk corresponding to the fixed disk is connected to the lower end of the valve operating shaft to constitute a valve. As a result, the movable disk slides in the front-rear direction to adjust the water discharge flow rate of the mixed hot water, and by rotating the lever handle, the movable disk rotates to adjust the water discharge temperature of the mixed hot water.

However, in the hot and cold water mixing faucet having such a configuration, the lever handle is tilted steplessly, so that the valve is fully opened at a stretch, resulting in an unnecessarily large amount of spouting water. In many cases, water is used with an unnecessarily large amount of discharged water, resulting in waste of water. Further, there is a problem that if the water is stopped at a stretch, a water hammer phenomenon is caused.

[0005] Therefore, a single lever type hot / water mixing faucet provided with a click mechanism so that the lever handle can be tilted or rotated stepwise has been developed.

[0006] As shown in, for example, Japanese Patent Application Laid-Open No. 7-280113, these click mechanisms are provided with uneven portions in the direction perpendicular to the tilt locus on the outer surface of a valve operating shaft connected to a movable disk. Provided or as disclosed in
As disclosed in Japanese Patent Publication No. 14422, an uneven portion is provided in the same direction as the tilt locus of the valve element operating shaft to provide resistance, and in any case, the tilt locus of the valve element operating shaft is provided. Irregularities were formed directly on the top.

[0007]

However, the above-mentioned conventional click mechanism has the following problems.

[0008] That is, in the case where the unevenness is provided directly on the outer surface of the valve element operating shaft in the direction perpendicular to the tilting locus to provide resistance, the position of the unevenness is determined by the size of the faucet. For example, the distance from the pivot of the valve operation shaft, that is, the height direction, restricts the tilt range at that position, and it is necessary to provide a plurality of uneven parts at appropriate intervals However, the design was difficult.

In addition, if the concave portion and the convex portion are slightly displaced from each other, the play is adversely affected, which directly affects the operability.

On the other hand, in the case of providing a resistance by providing an uneven portion oriented in the same direction as the tilting locus of the valve operating shaft, a force from below is applied in the fitting direction of the lever handle. , A separate member is required to press down the member constituting the click mechanism from above to prevent the click mechanism from coming off, increasing the number of parts, and complicating the configuration around the connecting portion between the lever handle and the valve body operation shaft. was there.

Also, in this case, since it is necessary to provide irregularities on the tilting locus of the valve operating shaft, even a slight displacement of the irregularities may adversely affect the operating force of the lever handle.

An object of the present invention is to provide a single lever type faucet click mechanism which can solve the above-mentioned problems.

[0013]

In order to solve the above-mentioned problems, according to the present invention, a lever handle is connected to a valve operating shaft which is tiltably and rotatably disposed on a faucet body,
In the single lever type faucet in which the flow rate and the water discharge temperature can be adjusted by operating the lever handle, the lever handle tilts on a virtual plane opposed to the tilt locus of the outer peripheral surface of the valve body operation shaft at a fixed interval. A plurality of resistance parts for providing resistance stepwise to the operation were provided.

According to the present invention, a fitting boss is provided at the base end of the lever handle so as to be fitted to and connected to the valve operating shaft. The resistance applying means provided with the resistance part of (1) is provided.

According to the third aspect of the present invention, the resistance applying means includes a plurality of rotation resistance portions for applying resistance stepwise to the rotation operation of the lever handle.

According to the present invention, the resistance applying means are arranged in a superposed state with each other.
A resistance applying base member and a resistance applying member, each of which is fitted with a valve body operation shaft and held between a lower surface of the fitting boss of the lever handle and an upper surface of the faucet main body; While a plurality of concave portions or convex portions were arranged in parallel, the resistance applying member was provided with at least one convex portion or concave portion corresponding to the concave portion or convex portion to constitute a resistance portion.

Further, according to the present invention, the resistance applying means comprises a resistance applying base member attached to the lever handle and a resistance applying member made of a wire attached to the faucet main body. A plurality of grooves were provided on the outer side surface of the application base member, and the resistance application member was formed with a linear convex portion engaging with the groove to constitute a resistance portion.

[0018]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a lever handle is connected to a valve body operating shaft which is tiltably and rotatably disposed on a faucet body, and the flow rate and water discharge temperature can be adjusted by operating the lever handle. In a single lever type faucet, a plurality of resistance portions are provided on a virtual plane opposed to a tilting trajectory of the outer peripheral surface of the valve body operation shaft at a constant interval, to provide resistance stepwise to the tilting operation of the lever handle. It is a thing.

The single-lever type faucet is provided with a valve mechanism having a fixed disk and a movable disk in the faucet body, a valve operating shaft is connected to the movable disk, and the lever handle is connected to the valve operating shaft. Then, the lever handle is tilted to adjust the water discharge flow rate, and the lever handle is rotated to change the mixing ratio of the hot and cold water, thereby providing a hot and cold water mixing faucet for adjusting the water discharge temperature.

The lever handle is provided at a top of a tubular faucet main body with a base end formed in a substantially cylindrical shape along the contour of the faucet main body, and extending from the base end. And a fitting boss portion fitted and connected to the valve body operating shaft at the base end portion, and the plurality of resistance portions provided on an outer portion of the fitting boss portion. It is preferable to provide the provided resistance applying means.

Further, the resistance applying means may include a plurality of rotation resistance portions for applying resistance stepwise to the rotation operation of the lever handle. Therefore, when the lever handle is tilted by operating the lever handle, a click feeling is generated for the user due to the plurality of resistance parts, and the valve is fully opened at a stretch to cause water splashing, or unnecessarily. It is possible to prevent water from being wasted by discharging water. Also,
Even when the water is stopped, the valve is not completely closed at a stretch, and there is no possibility of causing a water hammer phenomenon.

When the lever handle is operated to rotate the valve body operation shaft, a click feeling is also generated, and the click feeling becomes a guideline for temperature adjustment, or causes a sudden rotation to a high temperature side. In addition, it is possible to prevent unexpected hot water from being discharged. Therefore, the rotation resistance portion may be provided only on the hot water side.

It should be noted that the number of resistance portions that give a click feeling is
Both the tilting direction and the turning direction can be set appropriately.

Incidentally, the above-mentioned resistance applying means can be specifically configured as follows.

That is, as the resistance applying means, an insertion hole into which the valve body operation shaft can be inserted is formed, and the insertion hole is formed so as to be able to be arranged in a superposed state. The resistance applying base member includes a resistance applying base member and a resistance applying member held between the upper surface of the main body, and the resistance applying base member has a plurality of concave portions or convex portions arranged side by side. At least one convex portion or concave portion corresponding to the portion is provided to constitute a resistance portion.

The resistance applying base member and the resistance applying member are preferably formed in a U-shape having standing pieces on both sides, and a plurality of openings (recesses) are juxtaposed in the standing piece of the resistance applying base member. On the other hand, it is preferable to provide at least one projection (projection) on the corresponding piece of the resistance applying member,
A surface formed between the plurality of openings is defined as a resistance application surface, and resistance is applied when the protrusion of the resistance application base member crosses the resistance application surface while moving from one opening to the next opening, and a user clicks. Can give a feeling.

As described above, the valve operating shaft is inserted and disposed in a state where the resistance applying base member and the resistance applying member formed in a U-shape are superposed, thereby forming the resistance applying means.
At the same time as connecting the lever handle to the valve body operation shaft, the resistance applying means can be easily attached, and the resistance portion is a virtual plane opposed to the tilting locus of the outer peripheral surface of the valve body operation shaft at a certain interval. Since the resistance that causes a click feeling is applied in the direction perpendicular to the fitting direction of the lever handle, it is not adversely affected by the removal and insertion of the lever handle at the time of maintenance, and a member constituting the resistance applying means is removed. There is no danger.

In another embodiment, the resistance applying means comprises a resistance applying base member attached to the lever handle and a resistance applying member made of a wire attached to the faucet main body. While a plurality of grooves are provided on the outer surface of the member, the resistance imparting member may be formed with linear projections that engage with the grooves.

In this case, the resistance applying base member may be formed in a frame shape, and the plurality of grooves serving as the resistance portion together with the linear projections may be provided on the left and right side surfaces of the resistance applying base member at different intervals. That is, in order to obtain a multi-step click feeling, it is possible to form a plurality of grooves at appropriate intervals by providing them on the left and right side surfaces even if space is not sufficient with only one surface of the resistance applying base member. Becomes

Further, even in this case, for example, at least one convex portion is provided on the resistance applying base member, and the resistance applying base member is provided on the inner wall of the faucet which slides in conjunction with the turning operation of the lever handle. A plurality of concave portions corresponding to the convex portions are provided, and a rotational resistance portion is configured by the concave and convex portions, so that a click feeling can be generated even when adjusting the water discharge temperature.

As described above, the click mechanism according to the present invention can be manufactured at a low cost with a simple structure, and can substantially increase the installation area of the resistance portion.
Click feeling can be given in multiple stages.

In addition, since the position of the resistance portion is deviated from the tilting locus of the valve body drive shaft, the resistance portion is not directly affected by the operating force of the lever handle and the like, and the resistance due to the friction between the concave portion and the convex portion is large. The length can be set as appropriate separately from other operating forces such as the lever handle.
