  The present invention relates to a water discharge device, and more particularly, to a water discharge device provided with a rotation click mechanism of a water discharge tube that generates a click feeling at a predetermined rotational position when the water discharge tube is rotated.

  2. Description of the Related Art Conventionally, a water discharge device having a rotatable water discharge pipe is provided with a rotary click mechanism that generates a click feeling at a predetermined rotation position during rotation operation of the water discharge pipe and positions the water discharge pipe at that position.

  For example, in the following Patent Document 1, two steel balls are held in a holding recess of an annular case that rotates integrally with a water discharge pipe, and the steel ball provided on the support pipe side on the fixed side is rotated during the rotation operation of the water discharge pipe. There has been disclosed a structure in which a click feeling is generated by elastically engaging the steel ball with a concave portion of an annular receiving member located on the radially inner side.

  However, the one disclosed in Patent Document 1 is a click mechanism because the steel ball as the engaging portion is elastically engaged with the concave portion (engaged portion) of the annular receiving member provided on the radially inner side. In addition, there is a problem that the structure around it is enlarged in the radial direction.

  On the other hand, in Patent Document 2 below, a stopper ring is provided so as to rotate integrally with a joint pipe of a shower head, a storage groove is formed in the stopper ring, a spring and a spherical stopper are stored in the storage groove, and a spring is formed. The stopper is biased downward, and the stopper is elastically engaged with the corresponding recess of the holder at a predetermined rotational position of the joint pipe to generate a click feeling.

The thing disclosed in this Patent Document 2 is to generate a click feeling by engaging the stopper with the corresponding recess of the corresponding holder in the axial direction. Since a spring, a spherical stopper, and a corresponding concave portion are partially provided at a radially outer position with respect to the pipe so as to generate a click feeling, they are similar to those disclosed in Patent Document 1. The click mechanism and the surrounding structure are enlarged in the radial direction.
Further, the one disclosed in Patent Document 2 has a problem that it is difficult to generate a sufficient engagement force between the stopper and the recess, that is, to generate a sufficiently large click feeling.

It attaches to the said rotating shaft part by latching.

  According to a fifth aspect of the present invention, in any one of the first to fourth aspects, a rotation restricting projection for restricting the rotation of the water discharge pipe protrudes downward from a lower end of the rotating shaft portion, and the click member rotates in the rotation direction. The control projection has a C-shaped annular shape extending from one end to the other end in the circumferential direction, and each end in the circumferential direction of the click member is in contact with the one end and the other end of the rotation control projection in the circumferential direction. The rotation shaft is held by the rotation shaft portion, and the rotation restricting projection forms a rotation stop portion that restricts relative rotation of the click member with respect to the rotation shaft portion.

The rotation click mechanism generates a click feeling at a position where each corner of the lower end portion and the upper end portion coincides with the rotation direction.

Effects and effects of the invention

  As described above, the present invention includes a click member held in a state of rotating integrally with the rotation shaft portion at the lower end portion of the rotation shaft portion on the proximal end side of the water discharge pipe, and a convex formed downward on the lower surface of the click member. Corresponding to the engaging portion, a coil spring fitted coaxially so as to surround the rotating shaft portion on the upper side of the click member, and biasing the entire click member downward, The rotary click mechanism of the water discharge pipe is configured to include an engaged portion made of a concave portion or a convex portion provided in a fixed state upward on the holder side.

  According to the present invention, the coil spring having a large diameter and strong urging force can be used, and therefore the engaging portion and the engaged portion can be elastically engaged with a strong engaging force when the water discharge pipe is rotated. Thus, a click feeling due to the engagement can be greatly generated, and thereby the user can be surely and clearly notified that the water discharge pipe has reached the predetermined rotational position, and the positioning force The holding force at a predetermined rotational position with respect to the water discharge pipe can be increased.

Moreover, since this coil spring is arranged so as to surround the outer peripheral surface of the rotating shaft portion, even if such a large-diameter coil spring is provided, the click mechanism is particularly effective in the radial direction. There is no increase in size, and the space occupied by the coil spring can be made small, so that the structure of the peripheral portion can be made small in the radial direction.
According to the present invention, since the coil spring is provided coaxially with the rotary shaft portion along the outer peripheral surface of the rotary shaft portion, the click member is attached downward with equal force along the circumferential direction by the coil spring. You can

  According to a second aspect of the present invention, the engaging portions are provided at a plurality of locations along the circumferential direction, and the plurality of engaging portions are simultaneously elastically engaged with the corresponding engaged portions on the holder side. Thus, according to this second aspect, coupled with the fact that the urging force of the coil spring can be increased, a much more stable click feeling can be generated.

  According to a third aspect of the present invention, the click member is disposed so as to protrude downward from the lower end of the rotating shaft portion, and the engaging portion provided on the click member is formed at a position overlapping the lower end surface of the rotating shaft portion in the axial direction. Thus, according to the third aspect, unlike the case where the engaging portion is disposed at the radially outer position of the rotating shaft portion, the engaging portion does not cause the click mechanism to be particularly large in the radial direction. As a result, the click mechanism and the surrounding structure can be more effectively downsized in the radial direction.

  In addition, the urging force by the coil spring can be exerted on the engaging portion in the axial direction with high efficiency, and the elastic engaging force of the engaging portion with respect to the engaged portion can be generated with high efficiency, and the click feeling is more effective. Can be generated greatly.

Next, according to a fourth aspect of the present invention, the click member is attached to the rotary shaft portion by latching the elastic latching claw provided on one of the click member and the rotary shaft portion and the corresponding latching portion provided on the other side. In this way, there is no need for a separate member for attaching the click member to the rotating shaft portion, the number of required parts can be reduced, the structure of the click mechanism can be simplified, and the click member It is possible to reduce the man-hours for mounting and the assembling of the click mechanism.
Here, it is preferable to provide the elastic latching claw on the click member side, but it is also possible to provide it on the rotary shaft side.

It is formed in an annular shape, and each end of the click member in the circumferential direction is held on the rotating shaft portion in a state of contacting the one end and the other end of the rotation restricting projection in the circumferential direction. According to No. 5, the rotation restricting protrusion that restricts the rotation of the water discharge pipe itself can also serve as a rotation stop for the click member.
As a result, it is not necessary to provide a separate member for restricting relative rotation of the click member with respect to the rotation shaft portion, the number of required parts constituting the click mechanism can be reduced, and the structure of the click mechanism can be simplified. At the same time, the man-hours for assembling the click mechanism can be reduced.

Next, the operation of this embodiment will be described with reference to FIGS.
FIG. 11 (I) shows a state in which the water discharge pipe 12 is rotated to the right end in plan view. At this time, the engaging portions 56-1 and 56-2 formed by the convex portions of the upper click member 48 are the holder 16 It is in a state in which it is elastically engaged with the engaged portions 72-3 and 72-5 formed by the concave portions of the side lower click member 44.

Unlike the arrangement at the outer position in the radial direction, the engaging portions 56-1 and 56-2 do not cause the rotary click mechanism 38 to be particularly large in the radial direction. And the structure around it can be reduced in size in the radial direction effectively.

  In addition, the urging force by the coil spring 58 can be applied to the engaging portions 56-1 and 56-2 in the axial direction with high efficiency, and consequently the engaged portions 72-1, 72-2, 72-3, 72. The elastic engagement force of the engaging portions 56-1 and 56-2 with respect to -4 and 72-5 can be generated with high efficiency, and the click feeling can be increased more effectively.
