Description

  The present invention relates to a faucet operation knob, and more particularly to a faucet operation knob provided with a display for operation.

  Conventionally, there is a faucet described in Patent Document 1, for example. The faucet described in Patent Document 1 is provided with a curan operation knob and a shower operation knob as a faucet operation knob. In addition, characters and symbols for displaying the function of the operation knob, such as a currant function or a shower function, are formed on such an operation knob by printing on a silk screen or the like.

Japanese Patent Laid-Open No. 11-344137

  By the way, in such a conventional operation knob, a display is often formed at a part operated by an operator's finger or hand, for example, a part pressed by a finger or hand in a push type operation knob. For this reason, if a finger or hand hits the display or is rubbed with the use of the operation knob, the display print is peeled off and the display becomes invisible.

  The objective of this invention is providing the operation knob for water taps which can improve the durability of the display of an operation knob.

  In order to achieve the above object, an operation knob according to the present invention is an operation knob for operating a faucet, and an outer member is covered with a plate-like inner member sandwiched between ends of an operation mechanism of the faucet. In the outer member, a display hole for displaying the operation knob is provided at a position corresponding to the inner member.

  According to this configuration, a display hole for display related to the operation knob is provided at a position corresponding to the inner member in the outer member, so that a display is formed on the operation knob by printing. Unlike the above, there is no problem such as peeling off of the display. Further, since the inner member is located on the back side of the display hole, it is difficult for foreign matter to enter the display hole.

Therefore, the durability of the display of the operation knob can be enhanced.
In this case, it is preferable that the inner member is formed with a display projection that is fitted into the display hole.

  According to this aspect, since the protrusion of the inner member is fitted into the display hole of the outer member, it is preferable to prevent foreign matter from entering the display hole. Therefore, it can suppress that the display of an operation knob becomes dirty.

In this case, a mode in which the entire display hole is closed by the protrusion is preferable.
According to this aspect, since the entire display hole of the outer member is blocked by the protrusion, foreign matter does not enter the display hole. Therefore, the display of the operation knob can be further suppressed from becoming dirty.

In this case, it is preferable that the protrusions are formed on both surfaces of the inner member.
In this case, the shape of the outer peripheral edge of the protrusion is the same on both surfaces of the inner member, while the display portion formed on the surface of the protrusion is different on both surfaces of the inner member. A mode such as is preferable.

  According to this aspect, two types of display can be realized by one inner member when the one surface of the inner member is employed as the surface and when the other surface of the inner member is employed as the surface. . For this reason, for example, an inner member common to the operation knob for curan and the operation knob for shower can be used. Moreover, since the shape of the outer periphery of the protrusion part fitted to a display hole is the same on both surfaces of an inner member, a common outer member can be used with respect to each surface of an inner member. Therefore, the number of parts constituting the operation knob can be reduced.

Moreover, the aspect that the protrusion part is made into the same shape on both surfaces of the said inner member is preferable.
According to this aspect, for example, when the deterioration of the surface used as the front surface in the inner member proceeds, the surface used as the back surface can be newly set as the front surface. For this reason, the lifetime of an inner member can be extended.

  In addition, when assembling the inner member with respect to the outer member, the assembly direction of the inner member is not mistaken. Therefore, the operation knob can be easily assembled.

  According to the present invention, it is possible to improve the display durability of the operation knob.

The shower operation knob 10 </ b> B has a similar configuration, and includes a core 40, an outer cap 20, and an inner plate 30.

  Two types of display holes (a first display hole 23 and a second display hole 25) are formed through the bottom 21 of the outer cap 20. The first display hole 23 has a character shape of “PUSH”, that is, an alphabetic contour shape. The second display hole 25 has an oval shape extending along the arrangement direction of characters constituting the first display hole 23. A screw hole 29 is formed in the peripheral wall of the outer cap 20. The outer cap 20 is made of a highly corrosion-resistant metal material such as stainless steel or brass.

  A screw hole 49 corresponding to the screw hole 29 is formed in the peripheral wall of the core 40. In a state where the outer cap 20 is put on the core 40 with the inner plate 30 interposed therebetween, screws (not shown) are screwed into the respective screw holes 29 and 49, whereby the outer cap 20 is attached to the core 40. Is fixed. Incidentally, the core 40 is made of, for example, a synthetic resin material. The tip of the screw is locked to a shaft portion of an operation mechanism of the faucet 1 (not shown).

  As shown in FIG. 3A, two types of protrusions (first protrusion 33 </ b> A and second protrusion 35 </ b> A) are formed on one surface of the inner plate 30. The first protrusion 33A has a “PUSH” character shape corresponding to the first display hole 23, that is, an alphabet shape. The second protrusion 35A has an oval shape corresponding to the second display hole 25, and the second protrusion 35A is provided with a concave display portion 36A for displaying the currant function. In addition, Braille 34 for displaying the currant function is formed on the first protrusion 33A.

  As shown in FIG. 3B, on the other surface of the inner plate 30, two types of protrusions (first protrusion 33B and second protrusion 35B) are formed in the same manner as the one surface. Yes. However, a concave display portion 36B for displaying a shower function is formed on the second protrusion 35B. In addition, braille is not formed on the first protrusion 33B.

The inner plate 30 is made of a synthetic resin material such as ABS resin, and the protrusions 33A and 35A (33B and 35B) are integrally formed with the main body when the inner plate 30 is molded.
As shown in FIGS. 1, 4A, and 4B, in a state where the outer cap 20 is put on the core 40 with the inner plate 30 interposed therebetween, the protrusions 33A, 35A, 33B, and 35B of the inner plate 30 are The display holes 23 and 25 having the same shape and the same size as these are fitted. The top surfaces of the protrusions 33A, 35A, 33B, and 35B are located on the same plane as the display surface 22 of the outer cap 20. The entire display holes 23 and 25 of the outer cap 20 are closed by the protrusions 33A, 35A, 33B, and 35B.

Next, the operation of this embodiment will be described.
In the outer cap 20, display holes 23 and 25 for displaying the operation knobs 10 </ b> A and 10 </ b> B are transparently provided at positions corresponding to the inner plate 30, so that a display is formed on the operation knobs 10 </ b> A and 10 </ b> B by printing. Unlike the configuration, the problem of peeling off the display does not occur.

  In addition, since the inner plate 30 is located behind the display holes 23 and 25, it is difficult for foreign matter to enter the display holes 23 and 25. Moreover, since the inner plate 30 has a plate shape, the inner plate 30 sandwiched between the outer cap 20 and the core 40 can be made thin. For this reason, the physique of the inner plate 30 can be made small, and the physique increase of the whole operation knob 10A, 10B can be suppressed.

  Further, the projections 33A, 35A, 33B, and 35B of the inner plate 30 are fitted into the display holes 23 and 25 of the outer cap 20, and the entire display holes 23 and 25 are closed by the projections 33A, 35A, 33B, and 35B. Therefore, foreign matter does not enter the display holes 23 and 25.

According to the faucet operation knob according to the present embodiment described above, the following effects can be obtained.
(1) The outer cap 20 is put on the end of the operation mechanism of the faucet 1 with the plate-like inner plate 30 interposed therebetween. In the outer cap 20, display holes 23 and 25 for displaying the operation knobs 10 </ b> A and 10 </ b> B are transparently provided at positions corresponding to the inner plate 30.

  According to such a configuration, an increase in the size of the operation knobs 10A and 10B can be suppressed, and the display durability of the operation knobs 10A and 10B can be increased. Further, since foreign matter does not enter the display holes 23 and 25, the display of the operation knobs 10A and 10B can be suitably prevented from being dirty.

  (2) The shape of the outer peripheral edge of each protrusion 33A, 35A, 33B, 35B is the same shape on both surfaces of the inner plate 30, while the display part 36A formed on the surface of the second protrusion 35A, 35B, 36B has different shapes on both surfaces of the inner plate 30.

  According to such a configuration, when one surface of the inner plate 30 is adopted as a surface and when the other surface of the inner plate 30 is adopted as a surface, two types of display, that is, a curan, are performed by one inner plate 30. Function display and shower function display can be realized. For this reason, the common inner plate 30 can be used for the curan control knob 10A and the shower control knob 10B. Further, since the shape of the outer peripheral edge of the projections 33A, 35A, 33B, 35B fitted in the display holes 23, 25 is the same on both surfaces of the inner plate 30, Thus, a common outer cap 20 can be used. Therefore, the number of parts constituting the operation knobs 10A and 10B can be reduced.

(3) The outer cap 20 is made of a metal material, and the inner plate 30 is made of a synthetic resin material.
According to such a configuration, the feeling when the display holes 23 and 25 of the outer cap 20 are touched and the feeling when the projections 33A, 35A, 33B and 35B are touched are different. For this reason, the user can grasp | ascertain the display regarding the said operation knob 10A, 10B even if it has closed eyes by touching operation knob 10A, 10B. Therefore, even when the eyes cannot be opened, for example, when a shower is used for washing the hair, the operation knobs 10A and 10B can be identified.

Further, since the outer cap 20 and the inner plate 30 are different in color and gloss, the display of the operation knobs 10A and 10B can be easily made visually conspicuous.
