In addition, with the diversification of designs in the faucet devices in recent years and the globalization of needs, the appearance shape and the like of the operation handle of the faucet device have various shapes that emphasize design.
In operation handles of various shapes that emphasize such design, for example, the appearance of the side surface is a vertical planar shape such as a cubic shape or a rectangular parallelepiped shape, or an appearance that includes a straight portion. .
Therefore, from the viewpoint of improving the design of these external appearances, for example, the side surface of the operation handle and the side surface of the periphery of the pedestal, etc. are aligned with each other to produce a clean and integrated external appearance. Is preferred.
Therefore, how to improve the design by setting the positional relationship between these operation handles and the pedestals around the periphery has become a recently requested issue.
Also, in terms of design, for example, the relationship between the side of the operation handle and the outline of the square tile on the counter surface around it is set so that it looks parallel to each other when viewed from the user side, Alternatively, it is preferable to set it so that it looks flush within a predetermined plane.
Therefore, in recent years, how to improve the design by setting a small deviation in the shape and initial position of the side surface of the operation handle and the square tile of the counter surface has been a demanded issue.

  Therefore, the present invention has been made to solve the above-described problems, and an object thereof is to provide a water faucet device that can finely adjust the initial position of the operation handle and improve the design. It is said.

In order to solve the above-described problem, the present invention is a faucet device that discharges hot water or water and extends from the hot water source or the water supply source to the water discharge portion. A flow path forming section that forms a flow path, and an open / close valve that is provided in the flow path of the flow path forming section and controls the amount of water discharged from the water discharge section or the amount of water discharged from the water discharge section by opening and closing And an operation part that enables the opening / closing operation of the on-off valve by rotating operation, and a transmission part that transmits the operating force of the operation part to the on-off valve, and the on-off valve has a spindle part. The transmission section includes a spindle side connection section provided on one end side thereof and connected to the spindle section, and an operation side connection section provided on the other end side and connected to the operation section. The spindle-side connecting portion includes a first splice having a first predetermined pitch. There are formed, in the operating-side connecting portion, and characterized in that it is formed a second spline of the different second predetermined pitch from the first predetermined pitch.
In the present invention configured as described above, the spline (the first predetermined predetermined pitch) having a different pitch is used for the spindle-side connection portion on one end side and the operation-side connection portion on the other end side of the transmission portion that connects the on-off valve and the operation portion. Since the first spline having the pitch and the second spline having the second predetermined pitch are provided, the initial position of the operation unit can be finely adjusted without affecting the appearance of the faucet device.
Specifically, the rotational surface of the operating portion at the initial position is determined by the difference between the angle of the first predetermined pitch of the first spline of the spindle side connecting portion and the angle of the second predetermined pitch of the second spline of the operating side connecting portion. The angle inside can be finely adjusted.
Further, as the difference between the angle of the first predetermined pitch of the first spline and the angle of the second predetermined pitch of the second spline is set smaller, the angle in the rotation surface of the operation portion at the initial position is adjusted more finely. Can do.
Thereby, it is possible to improve the design properties of the operation unit and its peripheral part.

In the present invention, it is preferable that the transmission unit includes a discriminating unit capable of discriminating between the spindle side connection unit and the operation side connection unit.
In the present invention configured as described above, for example, when the operation side connection portion of the transmission portion is erroneously connected to the spindle portion of the on-off valve, the connection error can be noticed by the determination portion of the transmission portion.
Therefore, it is possible to prevent the connection portions at both ends of the transmission portion from being erroneously connected to the spindle portion and the operation portion of the on-off valve. Thereby, each of the spindle side connection part and the operation side connection part of the transmission part can be correctly connected to the spindle part and the operation part of the corresponding on-off valve.
On the other hand, if there is no discriminating means, the smaller the difference between the first predetermined pitch angle of the first spline and the second predetermined pitch angle of the second spline, the smaller the connection between the ends of the transmission unit. This also increases the possibility that parts will be connected by mistake. As a result, the transmission part, the spindle of the on-off valve, and the connection parts of the operation part may be damaged or malfunctioned, but these factors can be eliminated by the discriminating means of the present invention, and the pitch of each spline can be reduced. Even if the angle is small, correct construction can be performed.

In the present invention, preferably, the discrimination means is a display unit displayed on an outer surface of the transmission unit.
In the present invention configured as described above, by adopting a display unit displayed on the outer surface of the transmission unit as a means for determining each connection unit of the transmission unit, each connection unit of the transmission unit is connected to the spindle unit of the on-off valve. And when connecting to each of an operation part, it can carry out visually recognizing a display part.
Therefore, it is possible to accurately determine each of the spindle side connection portion and the operation side connection portion of the transmission portion, and it is possible to correctly connect to each of the spindle portion and the operation portion of the corresponding on-off valve.

In the present invention, it is preferable that the determination unit determines whether one of the first spline or the second spline is a male spline and the other of the first spline or the second spline is a female spline. Is.
In the present invention configured as described above, one of the first spline of the spindle-side connection portion and the second spline of the operation-side connection portion of the transmission portion is set as the male-side spline as the determining means for each connection portion of the transmission portion. Since the other of the first spline of the spindle-side connecting portion of the transmitting portion and the second spline of the operating-side connecting portion is set as a female-side spline, the connecting portion at both ends of the transmitting portion can be accurately discriminated visually. Can do.
Therefore, each of the spindle side connection portion and the operation side connection portion of the transmission portion can be correctly connected to the corresponding spindle portion and operation portion of the on-off valve.

In the present invention, it is preferable that the discrimination means is such that both the first spline and the second spline are male-side splines, and the outer diameters of the first spline and the second spline are different from each other. Is set to
In the present invention configured as described above, both the first spline and the second spline are male side splines. However, as a means for discriminating each connection portion of the transmission portion, the first spline and the second spline are externally connected. Since the diameters are set to be different from each other, it is possible to accurately determine the appearance of the connection parts at both ends of the transmission part.
Therefore, each of the spindle side connection portion and the operation side connection portion of the transmission portion can be correctly connected to the corresponding spindle portion and operation portion of the on-off valve.

In the present invention, preferably, the operation portion includes a handle connected to the operation side connection portion of the transmission portion, and the handle is formed in a directional shape.
In the present invention configured as described above, since the handle of the operation unit connected to the operation side connection unit of the transmission unit is formed in a shape having directionality, depending on the setting state of the initial position of the handle, The appearance is likely to be greatly affected.
However, since the spline having a different pitch is provided for each of the spindle side connection portion and the operation side connection portion of the transmission portion, the angle in the rotation surface of the handle can be finely adjusted.
Therefore, the design of the appearance of the entire handle and faucet device can be enhanced.

  According to the faucet device of the present invention, the initial position of the operation handle can be finely adjusted, and the design can be improved.

In the case of such a modification, the spindle 42 of the valve unit 22 connected to the spindle side connection portion 44 is provided with a female side spline that can mesh with the male side spline of the spindle side connection portion 44 of the transmission shaft member 26. That's fine. At the same time, a female-side spline may be provided on the inner peripheral side of the operation-side connecting portion 46, and a male-side spline may be provided on the outer peripheral surface of the lower-side connecting portion 28a connected to this.

Next, the operation of the faucet device 1 according to the first embodiment of the present invention will be described with reference to FIGS.
FIG. 9 is an enlarged partial view of the operation handle portion of the faucet device according to the first embodiment of the present invention shown in FIG.
First, in the operation handle 36 at the initial position P0 before setting shown in FIG. 9, the outline L1 at the front edge and the outline L2 at the rear edge are parallel to the horizontal line T1 extending in the left-right direction of the tile T on the deck surface C. If the outlines L3 and L4 on the left and right side edges are not parallel to the vertical line T2 extending in the front-rear direction of the tile T, the initial position of the operation handle 36 is finely adjusted.
At this time, the female-side spline 44 a of the spindle-side connecting portion 44 of the transmission shaft member 26 can be removed from the male-side spline 42 a of the spindle 42 of the valve unit 22.
Then, the transmission shaft member 26 can be attached to the male spline 42a of the spindle 42 again in a state where the angle of the initial position in the rotation plane centering on the central axes A1 and A2 is changed.
As a result, the meshing positions of the male side spline 42a of the spindle 42 and the female side spline 44a of the spindle side connection portion 44 of the transmission shaft member 26 are changed.
At this time, as shown in FIG. 9, the difference δ () between the pitch angle α of the female side spline 44a of the spindle side connection portion 44 of the transmission shaft member 26 and the pitch angle β of the male side spline 46a of the operation side connection portion 46. = Β−α) (for example, δ = 20 ° −18 ° = 2 °), the initial position of the operation handle 36 is within the range of the difference δ from the initial position P0 before setting to the initial position P1 after setting. Can be changed.
Further, as shown in FIG. 9, in the operation handle 36 at the initial position P1 after the change (after the setting is completed), the outline L1 at the front edge and the outline L2 at the rear edge are formed on the tile T on the deck surface C. It is parallel to the horizontal line T1 extending in the left-right direction.
Furthermore, as shown in FIG. 9, in the operation handle 36 at the changed initial position P1, the outlines L3 and L4 on both side edges thereof are also parallel to the horizontal line T2 extending in the front-rear direction of the tile T on the deck surface C. It is also parallel to the longitudinal line S1 in the front-rear direction in the plan view of the spout 2.

According to the faucet device 1 according to the first embodiment of the present invention described above, the meshing position between the male side spline 42a of the spindle 42 and the female side spline 44a of the spindle side connection portion 44 of the transmission shaft member 26 can be easily established. Can be changed. Thereby, the initial position of the operation handle 36 can be finely adjusted without affecting the appearance of the faucet device 1.
Further, the smaller the difference δ between the pitch angle α of the female spline 44a of the spindle side connecting portion 44 of the transmission shaft member 26 and the male side spline 46a of the operating side connecting portion 46, the smaller the initial position becomes. The angle in the rotation surface of the operation handle 36 can be adjusted more finely.
Accordingly, the design properties of the operation handle 36 and the peripheral portion thereof (the tile T of the deck surface C, the spout 2 and the like) can also be improved.

Next, according to the faucet device 1 according to the present embodiment, for example, the male side spline 46a of the operation side connection portion 46 of the transmission shaft member 26 is erroneously connected to the male side spline 42a of the spindle 42 of the valve unit 22. In this case, the connection error can be noticed, and it can function as a discrimination means for the connection portions 44 and 46 of the transmission shaft member 26.
Therefore, it is possible to prevent the connection portions 44 and 46 at both ends of the transmission shaft member 26 from being erroneously connected to the spindle 42 and the connection member 28 (operation handle 36) of the valve unit 22, respectively. Thus, each of the spindle side connection portion 44 and the operation side connection portion 46 of the transmission shaft member 26 can be correctly connected to the spindle 42 and the connection member 28 (operation handle 36) of the corresponding valve unit 22.
On the other hand, if there is no discrimination means of the present invention, the pitch angle α of the female side spline 44a of the spindle side connection portion 44 of the transmission shaft member 26 and the pitch of the male side spline 46a of the operation side connection portion 46 are assumed. The smaller the difference δ from the angle β is set, the higher the possibility that the connecting portions 44 and 46 at both ends of the transmission shaft member 26 are erroneously connected. As a result, the transmission shaft member 26, the spindle 42 of the valve unit 22, and each connection portion of the connection member 28 (operation handle 36) become a cause of breakage or malfunction.
On the other hand, in the faucet device 1 according to the present embodiment, these factors can be eliminated by the discriminating means, and the pitch angles α and β of the splines 44a and 46a of the connection portions 44 and 46 of the transmission shaft member 26 are small. However, the correct construction can be performed.
