The shaft member 60 is a fixed shaft 61 which is a shaft portion whose rotation with respect to the faucet main body 12 is restricted, and a shaft portion provided on the center side of the fixed shaft 61 and rotatable with respect to the faucet main body 12. It has a rotating shaft 62. The temperature of the mixed water can be adjusted by rotating the rotating shaft 62.

The temperature control handle 13 is attached to a tubular handle body 30 that can rotate integrally with the rotating shaft 62 of the shaft member 60 and a fixed shaft 61 of the shaft member 60, and cannot rotate integrally with the rotating shaft 62. It includes a non-rotating member 40. Further, the temperature control handle 13 includes a fixing member 50 for fixing the handle body 30 to the shaft member 60.

Next, each member of the temperature control handle 13 will be described.
As shown in FIGS. The side (faucet body side) is open. The bottom wall 32 is provided with an insertion hole 33 into which the fixing member 50 is inserted. The insertion hole 33 has an inner peripheral wall 33A extending in the axial direction, and a groove-shaped unevenness 33B extending in the axial direction is formed on the other end side (faucet main body side) of the inner peripheral wall 33A. ing. The unevenness 33B functions as a fitting portion that fits with the groove-shaped unevenness 62A formed on the rotating shaft 62 of the shaft member 60 in the assembly configuration of the temperature control handle 13, which will be described later.

The handle body 30 is provided with a push button 20 that rotates integrally with the handle body 30 and can be pushed down from the outside of the handle body 30 in the radial direction and a push button 20 in the radial direction. A urging member 21 is attached. The peripheral wall 31 of the handle body 30 is provided with a hole 34 for exposing the push button 20, and the push button 20 is inserted into the hole 34 from the inner peripheral side of the peripheral wall 31. The push button 20 has a main body portion 20A inserted into the hole portion 34 and a regulating portion 20B protruding from the main body portion 20A to the other end side (faucet main body side). Further, a wall portion 35 is provided on the outer periphery of the inner peripheral wall 33A at a position facing the hole portion 34, and an urging member 21 is attached between the wall portion 35 and the main body portion 20A of the push button 20.

The non-rotating member 40 is an annular member having a through hole 41 through which the fixed shaft 61 of the shaft member 60 of the faucet main body 12 is inserted. The diameter of the through hole 41 is configured to be substantially equal to the outer diameter of the fixed shaft 61. A groove-shaped unevenness 41A extending in the axial direction is formed on the inner circumference of the through hole 41 over the entire circumference. The unevenness 41A is configured so that the shape is different from the other unevenness only at one place. On the outer peripheral side of the through hole 41 on the end surface on one end side of the non-rotating member 40, an arc-shaped first wall portion 42 along the rotation direction of the handle body 30 and an inner peripheral side of the first wall portion 42. At intervals, an annular second wall portion 43 along the concentric circles of the first wall portion 42 is provided. Further, a third wall portion 44 connecting the first wall portion 42 and the second wall portion 43 is provided on the end surface of the non-rotating member 40 on one end side.

A predetermined space S is formed between the first wall portion 42 and the second wall portion 43 along the rotation direction of the handle main body 30. This space S functions as a passage through which the regulation portion 20B of the push button 20 moves when the handle body 30 rotates beyond a predetermined position in the lock mechanism described later. Therefore, this space S is configured to be slightly larger than the thickness of the restricting portion 20B of the push button 20, so that the restricting portion 20B can move smoothly. Then, the second wall portion 43 functions as a support member that supports the restricting portion 20B of the push button 20 from the inside in the radial direction with the restricting portion 20B of the push button 20 sandwiched between the second wall portion 43 and the first wall portion 42.

Next, the assembly configuration of the temperature control handle 13 will be described.
First, the fixed shaft 61 of the shaft member 60 of the faucet body 12 is inserted into the through hole 41 of the non-rotating member 40. Since the fixed shaft 61 is provided with the unevenness 61A corresponding to the unevenness 41A formed on the inner circumference of the through hole 41 of the non-rotating member 40, the fixed shaft 61 is non-rotated with reference to the unevenness having a different shape at only one place. The moving member 40 is attached in a state of being fitted to the fixed shaft 61. In this state, the non-rotating member 40 is restricted from rotating with respect to the faucet body 12. Then, the non-rotating member 40 is fixed to the faucet main body 12 by engaging the claw portion 19 of the faucet main body 12 with the engaging hole 45 of the non-rotating member 40. Next, the handle body 30 to which the push button 20 and the urging member 21 are attached is attached to the rotating shaft 62. At this time, the groove-shaped unevenness 62A provided on the rotating shaft 62 of the shaft member 60 fits into the groove-shaped unevenness 33B provided on the inner peripheral wall 33A of the insertion hole 33 of the handle body 30. As a result, the handle body 30 can rotate integrally with the rotating shaft 62. Then, the fixing member 50 is inserted into the insertion hole 33 of the bottom wall 32 of the handle body 30. The flange portion 52 of the fixing member 50 fits into the insertion hole 33 of the bottom wall 32 in a state where the main body portion 51 of the fixing member 50 is inserted into the insertion hole 33. Then, the engaging portion 53 of the fixing member 50 engages with the tip portion 62B protruding from the rotating shaft 62 of the shaft member 60, so that the handle body 30 does not easily come off from the shaft member 60. It is attached to the stopper body 12.

Next, the locking mechanism of the temperature control handle 13 will be described.
In the present embodiment, the push button 20, the urging member 21, and the non-rotating member 40 form a locking mechanism.

As shown in FIGS. 4A and 4B, when the temperature control handle 13 is attached to the faucet main body 12, the regulation portion 20B of the push button 20 comes into contact with the end portion 42A of the first wall portion 42. As a result, the rotation of the temperature control handle 13 to the side higher than the predetermined temperature is restricted.

As shown in FIG. 4C, when the state in which the rotation of the temperature control handle 13 is restricted is released, the push button 20 is in the pressed state. Along with this, as shown by the arrow, the position of the restricting portion 20B of the push button 20 is displaced inward in the radial direction from the end portion 42A of the first wall portion 42. As a result, as shown by an arrow in FIG. 4D, the regulating portion 20B moves in the space S between the first wall portion 42 and the second wall portion 43, so that the temperature control handle 13 is heated to a predetermined temperature. It becomes possible to rotate to the higher temperature side.

Then, the temperature control handle 13 that has rotated to a temperature higher than the predetermined temperature is restricted from further rotation by the restricting portion 20B of the push button 20 coming into contact with the third wall portion 44. Therefore, the third wall portion 44 functions as a stop portion for stopping the rotation of the handle body 30 that rotates beyond a predetermined position.

Next, the operation of this embodiment will be described.
As shown in FIG. 4D, when the temperature control handle 13 is rotated to a temperature higher than a predetermined temperature, the restricting portion 20B of the push button 20 is formed between the first wall portion 42 and the second wall portion 43. The space S provided between them is moved. That is, the restricting portion 20B of the push button 20 is supported by the first wall portion 42 and the second wall portion 43 from both the radial outer side and the radial inner side, and the first wall portion 42 and the second wall portion 43. Will move between. As a result, even if the push button 20 tries to incline in the direction in which the regulation portion 20B side is radially inward due to the urging force from the urging member 21 against the push button 20, the regulation portion 20B is supported by the second wall portion 43. As a result, the inclination of the push button 20 is suppressed.

Next, the effect of this embodiment will be described.
(1) When the handle body 30 is in a rotation position exceeding a predetermined position, the regulation portion 20B of the push button 20 is sandwiched between the handle body 30 and the first wall portion 42 to support the regulation portion 20B from the inside in the radial direction. By providing the two wall portions 43, the inclination of the push button 20 can be suppressed.

(2) The non-rotating member 40 and the second wall portion 43 are integrally formed. Therefore, since the number of parts can be reduced, the temperature control handle 13 can be easily assembled to the faucet main body 12.

(3) A third wall portion 44 is provided on the inner peripheral side of the first wall portion 42 to stop the rotation of the handle body 30 when the restricting portion 20B comes into contact with the regulating portion 20B. The second wall portion 43 is formed in an annular shape, and the second wall portion 43 is also arranged at a position that supports the restricting portion 20B of the push button 20 in contact with the third wall portion 44 from the inside in the radial direction. .. Therefore, since the inclination of the regulating portion 20B in contact with the third wall portion 44 can be suppressed by the second wall portion 43, it is possible to prevent the regulating portion 20B from getting over the third wall portion 44.

Further, since the restricting portion 20B is suppressed from getting over the third wall portion 44, it is possible to prevent the handle body 30 from being excessively rotated by the restricting portion 20B getting over the third wall portion 44. can.

This embodiment can also be modified and implemented as follows. It is also possible to appropriately combine the configurations of the above-described embodiment and the configurations shown in the following modified examples.
As shown in FIG. 5A, the restricting portion 20B is provided with a bent portion 20C that bends inward in the radial direction of the handle body 30, and the second wall portion 43 has a recess into which the bent portion 20C is inserted. 43A may be formed.

The recess 42B may be formed. Further, the bent portion 20C is provided on both the radial inner side and the outer side of the handle body 30 in the regulating portion 20B, and the bent portion 20C is inserted into both the first wall portion 42 and the second wall portion 43. 43A may be formed. By inserting the bent portion 20C into the recesses 42B and 43A, the contact area between the regulation portion 20B and the first wall portion 42 and the contact area between the regulation portion 20B and the second wall portion 43 can be increased, so that the push portion can be pushed. The inclination of the button 20 can be suitably suppressed.

-In the present embodiment, the third wall portion 44 is provided so as to connect the first wall portion 42 and the second wall portion 43, but the present embodiment is not limited to this embodiment. The third wall portion 44 may be connected to only one of the first wall portion 42 and the second wall portion 43, or may not be connected to both and may be provided independently.

The second wall portion 43 of the non-rotating member 40 does not have to be formed in an annular shape. For example, as shown in FIG. 6, the second wall portion 43 may be provided in an arc shape only on the inner peripheral side of the first wall portion 42. Further, the place where the non-rotating member 40 is attached is not limited to the fixed shaft 61. As long as it cannot rotate integrally with the rotating shaft 62, it may be attached to the faucet body 12 other than the fixed shaft 61. Examples of the faucet main body 12 other than the fixed shaft 61 include a cover 12A of the faucet main body 12.

The first wall portion 42 and the second wall portion 43 of the non-rotating member 40 may be formed as separate bodies. For example, as shown in FIG. 7, both members are attached to the fixed shaft 61 of the shaft member 60 by using the non-rotating member 70 having the first wall portion 42 and the annular member 71 having the second wall portion 43. You may.

In the present embodiment, the non-rotating member 40 is attached to a shaft member 60 having a rotatable rotating shaft 62 protruding from the faucet main body 12, but the non-rotating member 40 is not used. It may be the one that has been done. For example, as shown in FIG. 8, a rotatable rotating shaft 62 protruding from the faucet main body 12 and a rotating shaft 62 protruding from the faucet main body 12 and rotating in a non-rotatable state with respect to the rotating shaft 62. A shaft member 60 having an arc-shaped first wall portion 42 provided along the rotation direction of the shaft 62 may be used, and an annular member 71 having the second wall portion 43 may be attached to the shaft member 60. That is, the fixed shaft 61 and the first wall portion 42 are integrally provided so that the fixed shaft 61 has the first wall portion 42, and the annular member 71 having the second wall portion 43 is separately fixed. It may be configured to be attached to 61. In this case, the temperature control handle 13 is configured to include a handle body 30 to which a push button 20 and an urging member 21 are attached, an annular member 71, and a fixing member 50. The lock mechanism of the temperature control handle 13 is composed of a push button 20, an urging member 21, and a second wall portion 43. Further, instead of the configuration in which the fixed shaft 61 and the first wall portion 42 are integrally provided, the configuration in which the cover 12A of the faucet main body 12 and the first wall portion 42 are integrally provided may be used.

-In the present embodiment, the push button 20 and the urging member 21 are composed of separate members, but they may be integrally configured. For example, the push button 20 may be formed of an elastic member, and when the push button 20 is pushed down, the push button 20 itself may be urged outward in the radial direction by the repulsive force of the push button 20 itself against the wall portion 35. In this case, the push button 20 has a urging member.

The temperature control handle 13 may be configured not to include the fixing member 50.
The configuration relating to the push button 20 in the temperature control handle 13 may be applied to the switching handle 14.
