Description

The present invention relates to a faucet button.

Patent Document 1 describes a faucet equipped with a push button.
As shown in FIGS. 17 and 18, when the push button 61 is pressed, the contact portion 62 on the back surface of the push button 61 presses a pusher (not shown). When the pusher is pressed, an on-off valve unit (not shown) is operated. By operating the on-off valve unit, water is stopped from being discharged from the water spout 64.

The push button 61 has a closing member 63 that closes the opening 61a of the push button 61. The closing member 63 has snap fixing protrusions 63a at four locations on the back surface. The closing member 63 is attached to the push button 61 by pushing the closing member 63 from above the push button 61 and engaging the snap fixing protrusion 63a with the opening 61a of the push button 61.

JP2009-079432A

By the way, in the faucet 60 of Patent Document 1, when attaching the closing member 63 as a button cover to the push button 61 as an inner button, it is necessary to align the four snap fixing protrusions 63a to the correct positions. Ta. If the four snap fixing protrusions 63a are not in the correct positions, the button cover cannot be attached because the snap fixing protrusions 63a will not engage with the openings 61a of the inner button. However, since it is difficult to perform the attachment work while visually checking the position of the snap fixing protrusion 63a, there is a problem in that it is difficult to attach the button cover to the inner button.

A faucet button for solving the above problem is a faucet button including an inner button and a button cover attached to the inner button, the inner button having a first engaged portion and a button cover attached to the inner button. The button cover has a second engaged portion, and the button cover has an abutting engaging portion that engages the first engaged portion, and the abutting engaging portion abuts the first engaged portion. The main feature is that the button cover has a rotating engagement portion that engages with the second engaged portion by rotating the button cover around the abutting engagement portion in a state where the button cover is in contact with the second engaged portion.

According to this configuration, when the button cover is rotated around the abutment and engagement part with the abutment and engagement part of the button cover in contact with the first engaged part of the inner button, the button cover rotates. The dynamic engagement portion can be engaged with the second engaged portion of the inner button. Therefore, it is possible to easily attach the button cover to the inner button.

Regarding the above-mentioned faucet button, it is preferable that the inner button has a regulating part that regulates movement of the button cover along a rotation axis direction of the button cover. According to this configuration, it is possible to suppress misalignment of the button cover along the rotation axis direction of the button cover.

Regarding the faucet button, it is preferable that the inner button has the regulating portions on both outer sides of the button cover along the rotation axis direction of the button cover. According to this configuration, the restriction portion can suppress interference between the button cover and other members located on both outer sides of the button cover.

Regarding the faucet button, it is preferable that the first engaged part is a groove part, and the abutment engaging part is a claw part. According to this configuration, the button cover can be easily rotated with the claw portion in contact with the first engaged portion.

Regarding the faucet button, the button cover has a top cover portion that covers the top surface of the inner button, a front cover portion that covers the front surface of the inner button, and a bottom cover portion that covers the bottom surface of the inner button. Preferably, the upper surface cover portion has the abutment engagement portion, and the lower surface cover portion has the rotation engagement portion. According to this configuration, the distance between the abutting engagement portion, which is the center of rotation, and the rotation engagement portion becomes relatively large. Therefore, the button cover is likely to be elastically deformed when the rotational engaging portion of the lower surface cover portion is engaged with the second engaged portion of the inner button. Therefore, it becomes easier to form an engaged state between the rotational engaging portion and the second engaged portion of the inner button. Moreover, when the button cover is viewed from the front, the abutment engagement part and the rotation engagement part can be made difficult to see. Therefore, the design of the button cover can be improved.

According to the faucet button of the present invention, it is possible to easily attach a button cover to an inner button.

In addition, by rotating the button cover 40 around the claw portion 42a with the claw portion 42a in contact with the groove portion 32c, the button cover 40 is engaged with the convex portion 33b (second engaged portion) of the bottom wall 33 of the inner button 30. It has a mating through hole 43b (rotating engagement part).

The through hole 43b of the bottom cover part 43 is inserted into the inner button 30 by a simple operation of rotating the button cover 40 around the claw part 42a with the claw part 42a of the button cover 40 in contact with the groove part 32c of the inner button 30. can be engaged with the convex portion 33b of. Therefore, the work of attaching the button cover 40 to the inner button 30 can be easily performed.

(2) By bringing the claw portion 42a of the button cover 40 into contact with the groove portion 32c of the inner button 30, the button cover 40 can be rotated in a stable state while suppressing movement of the claw portion 42a in the front-back direction. I can do it.

(3) The button cover 40 can be attached while visually confirming that the claw portion 42a of the button cover 40 is in contact with the groove portion 32c of the inner button 30. Therefore, positioning of the button cover 40 with respect to the inner button 30 becomes easy.

(4) The inner button 30 has a pair of partition walls 32d (regulating portions) that restrict movement of the button cover 40 along the rotation axis direction of the button cover 40. Therefore, displacement of the button cover 40 along the rotation axis direction of the button cover 40 can be suppressed.

(5) The inner button 30 has a pair of protruding walls 35, 36, and 37 (regulating portions) on both outer sides of the button cover 40 along the rotation axis direction of the button cover 40. Therefore, displacement of the button cover 40 along the rotation axis direction of the button cover 40 can be suppressed. Further, the pair of protruding walls 35, 36, and 37 can suppress interference between the button cover 40 and other members located outside the button cover 40 in the left-right direction, such as the peripheral wall 25b of the frame member 25.

(6) The button cover 40 has a top cover section 42 that covers the top surface of the inner button 30, a front cover section 41 that covers the front surface of the inner button 30, and a bottom cover section 43 that covers the bottom surface of the inner button 30. The upper cover part 42 has a claw part 42a, and the lower cover part 43 has a through hole 43b.

The distance between the claw portion 42a of the upper surface cover portion 42, which is the center of rotation, and the through hole 43b of the lower surface cover portion 43 becomes relatively large. Therefore, when the through hole 43b of the lower surface cover part 43 is engaged with the convex part 33b of the inner button 30, the button cover 40 is easily elastically deformed. Therefore, it becomes easier to form an engaged state between the through hole 43b of the button cover 40 and the convex portion 33b of the bottom wall 33 of the inner button 30. Furthermore, since the top cover part 42 has the claw part 42a and the bottom cover part 43 has the through hole 43b, the claw part 42a and the through hole 43b are made difficult to see when the button cover 40 is viewed from the front. Can be done. Therefore, the design of the button cover 40 can be improved.
