BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water spout stand capable of changing a water spout direction of a water spout as needed.

[0002]

2. Description of the Related Art A water spout stand such as a washstand, a shampoo table, a sink, a shower head installed in a bathroom unit, or the like, which can adjust a spout direction when used, has been conventionally known. No. 3572 is known. As shown in FIG. 6, the water discharge position variable support device 75 has a columnar rod 70 that supports a water discharger (not shown) at the distal end, which is inserted into a guide cylinder 80 so as to be able to advance and retreat and to rotate. 7
A hose 90 is inserted into the inside of the hose 90, and a water discharger is connected to the end of the hose 90. Annular grooves 71 and 72 are respectively formed on the outer peripheral surface slightly below the middle in the longitudinal direction of the rod 70 and near the lower end, and a plurality of grooves are formed in the bottom of the annular grooves 71 and 72 as shown in FIG. The concave portion 73 is provided continuously in the circumferential direction. On the other hand, as shown in FIG. 7, an elastic piece 81 is integrally provided by making a U-shaped notch in the cylindrical wall of the guide cylinder 80.
A hemispherical engagement member 82 is formed on the inner surface of the distal end portion of the head.

As described above, when the rod 70 is moved up and down by the elasticity of the engaging member 82 against the outer peripheral surface of the rod 70, the engaging member 82 is moved to one of the upper and lower annular grooves 71, The rod 70 can be held at the height at the time of fitting by fitting into the concave portion 73 of 72. When the rod 70 is rotated to change the water discharge direction at any time, the engagement member 81 switches the fitting to the plurality of recesses 73 in the annular grooves 71 and 72, and the rod 70 is weak against rotation. With a certain degree of resistance, it can be locked in a desired water discharge direction and can maintain that water discharge direction. Therefore, there is an advantage that the height and direction of the water spouting device can be freely adjusted, the usability is improved, and the adjustment can be performed by one-handed operation, especially during hair washing. Further, the force for holding the water discharging device in a desired water discharging direction is appropriately adjusted by the pressing force of the elastic piece 81.
Is smaller than the depths of the annular grooves 71 and 72, so that rotating the rod 70 in a horizontal plane can be performed with a lighter external force than moving the rod 70 up and down.

[0004]

[0008]

Embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, a water spout stand 10 of the present invention is provided on a top plate 1 such as a sink or a sink (not shown).
A pipe 40 forming a part of the support rod 8 is inserted into a substantially cylindrical lower holder 20 fixed with screws by the flange 2 so as to be able to advance and retreat and to be rotatable. ) Is inserted into the pipe 40, and the shower head 11 is connected to the end of the hose and supported by the shower holder 12.

The entire water spout stand 10 is fixed to the top 1 via a lower holder 20 fixed vertically to the top 1. The lower holder 20 is inserted into the mounting hole 3 formed in the top plate 1, the sheet packing 4 is sandwiched between the upper flange portion 21 and the upper surface of the top plate 1, and the lower surface of the top plate 1 is provided on the lower surface of the top plate 1. Further, the packing 5 and the slip plate 6 are fixed to each other, and the flange 2 is screwed to a screw 22 provided on the outer periphery of the lower holder 20. A substantially cylindrical upper holder 60 having a diameter larger than that of the flange portion 21 is screwed to a screw 23 provided on the outer periphery of the flange portion 21 of the lower holder 20. In the present embodiment, these lower holders 20 and The upper holder 60 constitutes the holder 7.

In this embodiment, the support rod 8 is constituted by the pipe 40, the base nut 50, and the shower holder 12, and is connected to a water faucet inside the lower holder 20 toward the lower side of the top plate 1. Pipe 4 with built-in hose
0 is inserted so as to be able to move forward and backward and rotate freely. Pipe 4
A base nut 50 is fitted and fixed to the outer periphery of the upper part of the “0”. A flange portion 51 is provided at a lower portion of the base nut 50, and the shower holder 12 is fitted and fixed to the outer periphery of the base nut 50 so that the opening edge 13 at the base end thereof abuts on the flange portion 51. I have. The shower holder 12 fixed to the pipe 40 via the base nut 50 is removably mounted on the upper holder 60 via the flange portion 51 of the base nut 50. As shown in FIG.
A large number of opposed grooves 52 are formed on one lower surface, while two opposed fitting projections 61 provided at positions corresponding to the respective grooves 52 are provided on the upper surface of the upper holder 60,
When the shower holder 12 is placed on the upper holder 60, the fitting protrusions 61 are fitted into the grooves 52 to hold the shower holder 12 so as not to rotate. Since a large number of grooves 52 are provided, the rotational position of the shower holder 12 can be finely adjusted.

As shown in FIG. 2, a set of forward / backward restricting engagement pieces 23 for restricting forward / backward movement is provided at the lower portion of the lower holder 20 so as to extend from the opening edge 27 thereof. It is protruding. In addition, a rotation restricting engagement piece 24 for restricting rotation, which has a substantially rectangular shape, is similarly protrudingly provided on the opening edge 27 so as to face the opposing line vertically. As shown in FIG. 3, a pipe 4
0 engages with an engaging ridge 41 serving as a forward / backward restricting portion provided on the outer periphery in a circular shape, so that the pipe 4
An engagement ridge 25 that regulates the advance and retreat of 0 is provided. As shown in FIG. 4, the tip of the rotation restricting engagement piece 24 is formed to have substantially the same width as the length between the projections 42 as rotation restricting portions provided at equal intervals on the outer periphery near the lower end of a pipe 40 described later. The tip of the rotation restricting engagement piece 24 constitutes a projection 28 that is engaged between the projections 42 of the pipe 40. Further, two groove-shaped concave portions 26 with which the projections 42 are engaged are provided continuously inside the convex portions 28 in the circumferential direction.
Since the concave portion 26 is provided in a long groove shape, it can be smoothly engaged with the projection 42. Lower holder 20
Are formed of polyacetal, and are integrally formed into a thin wall;
Has a pressing force in the direction of the outer peripheral surface of the pipe 40. Also,
The forward / backward restricting engaging piece 23 is provided in a substantially short rectangular shape, and the turning restricting engaging piece 24 is provided in a substantially long rectangular shape. Is configured. The lower holder 20 is not limited to polyacetal and may be made of another elastically deformable synthetic resin.

The lower end of the pipe 40 has a rotation restricting engagement piece 2
4 is provided with a flange portion 43 that abuts against the tip of the pipe 40 and restricts further lifting of the pipe 40. On the outer periphery of the pipe 40 immediately above the flange portion 43, eight projections 42 having a size such that the apex thereof fits within the outer diameter of the flange portion 43 are provided circumferentially at equal intervals. As described above, each projection 42 is formed at substantially the same width as the horizontal width of the rotation restricting engagement piece 24 so that the rotation restriction engaging piece 24 is engaged therebetween. In addition, the shape is a convex shape corresponding to the concave portion 26 and the convex portion 28 so that the convex portion 28 formed by the rotation restricting engagement piece 24 and the concave portion 26 provided inside the convex portion 28 can be appropriately engaged. Is formed. In addition, on the outer periphery of the pipe 40, a circumferential engagement member is provided at a position where the rotation restricting engagement piece 24 engages with the projection 42 and the engagement protrusion 25 of the advance / retreat restriction engagement piece 23 engages. A ridge 41 is provided.

The water spout stand 10 constructed as described above.
In this case, since the forward / backward restricting engagement piece 23 is elastically pressed against the outer peripheral surface of the pipe 40, when the pipe 40 is pulled upward, the engagement ridge 25 engages with the engagement ridge 41, A height of 40 is maintained. At the same time, the rotation restricting engagement piece 2 elastically pressed against the outer peripheral surface of the pipe 40 is also provided.
4 engages with the projection 42 at the lower end of the pipe 40. The rotation restricting engagement piece 24 has a width substantially equal to the interval between the projections 42, and both sides thereof constitute a convex portion 28, and a concave portion 26 engaging with the projection 42 is continuously provided inside the convex portion 28. Therefore, the projection 42 is engaged between the projections 42, or the projection 42 is engaged with and held in any of the concave portions 26. Therefore, when the pipe 40 is rotated in this state, the pipe 40 provided with the eight projections 42 can be held in 24 desired rotation directions. Usually, when the pipe 40 is formed by injection molding, it becomes a hindrance to the mold splitting. Therefore, the number of the projections 42 is often limited to about eight. Therefore, even when the number of the projections 42 of the pipe 40 is limited, by employing the above configuration, it is possible to hold the pipe 40 at a greater number of fine positions.

At the position where the pipe 40 is held as described above, the pressing force at the tip of the rotation restricting engagement piece 24 is smaller than that of the advance / retreat restriction engaging piece 23 as described above. The holding force in the rotating direction of the pipe 40 due to the engagement of the mating piece 24 with the projection 42 is inferior to the holding force in the moving direction of the pipe 40. Accordingly, turning the pipe 40 can be performed with a lighter external force than lowering the pipe 40 downward.

As described above, the pipe 40 is regulated so as not to be unnecessarily rotated by a small external force such as vibration of a wash basin. In addition, the pipe 40 is used to change the water discharge direction of the shower holder 12 as necessary. When rotating 40, the engaged state is easily released. On the other hand, the holding force in the vertical direction of the pipe 40 is
Because it is stronger than the holding force in the rotation direction of
When changing the water discharge direction, the operability is improved without the shower holder 12 being lowered against the user's will. The holding force of the pipe 40 in the reciprocating or rotating direction is appropriately adjusted depending on the shapes of the engaging ridge 25 and the engaging ridge 41, or the concave portion 26, the convex portion 28, and the projection 42, respectively. In the present embodiment, both the forward and backward restricting engagement piece 23 and the rotation restricting engagement piece 24 are integrally formed of the same material, and the difference in length makes a difference in the pressing force at the distal end portion. The holding force in the rotation direction of the pipe 40 by the engagement piece 24 is configured to be weaker than the holding force in the movement direction by the advance / retreat regulating engagement piece 23. When the support rod 8 is lowered to the maximum, the fitting projection 61 provided on the upper holder 60 is fitted in the groove 52 on the lower surface of the flange portion 51 of the base nut 50 in a desired direction, and Unnecessary rotation of the rod 8 is restricted.

This embodiment has the following effects because it is configured as described above. The water discharge height and the water discharge direction can be adjusted at the time of use with a simple structure, so that the water discharge device stand 12 that can be easily maintained can be obtained. Further, when the injection molding of the pipe 40 causes a problem in the mold splitting, the projections 4 provided on the pipe 40 may be used.
Even when the number of protrusions is limited to 2, the water discharge direction of the shower holder 12 can be finely adjusted at a very large number of positions obtained by multiplying the number of projections 42 by the number of recesses 26 provided in the rotation restricting engagement piece 24. Can hold. Further, since the projections 42, the concave portions 26 and the convex portions 28 are all provided at equal intervals, the support rod 8
In any position, the engagement state in the rotation direction is kept substantially constant, the holding force in the rotation direction can be stabilized, and the operability can be further improved.

The present invention is not limited to the above embodiment. In the water spout stand of the present invention, the number of the concave portions 26 is not limited to two, and one or three or more may be continuously provided. And finer adjustment of the water discharge direction is possible. However, if the concave portions 26 are provided more than necessary, the size of each concave portion 26 must be small,
Therefore, the size of the projection 42 to be engaged with the projection must be reduced, and it is difficult to secure an appropriate engagement state between the recess 26 and the projection 42 in the rotation control of the pipe 40. It is preferable to provide about three concave portions 26.

The rotation restricting engagement pieces 24 are not limited to being provided in a pair facing each other, and it is possible to provide three or more rotation restriction engagement pieces at equal intervals. In addition, the pressing force for holding the rotation direction of the support rod 8 becomes unnecessarily strong, and the material and the manufacturing cost increase. Therefore, it is preferable that the number of the opposing pairs is set to three or about three at equal intervals. Also, the advance / retreat regulating engaging piece 23 is not limited to being provided in a pair facing the rotation regulating engaging piece 24 as in the case of the above-described rotation regulating engaging piece 24. It is preferable that the number be kept to about two. Furthermore, the rotation restricting engagement piece 24 is provided wider in the lateral direction,
Although it is possible to increase the number of the concave portions 26 corresponding to this,
Since the pressing force may be unnecessarily strong similarly to the above, it is preferable that the pressing force is provided narrow.

Further, the pressing force is adjusted irrespective of the difference in length by providing the advance / retreat restricting engagement piece 23 and the rotation restricting engaging piece 24 as a separate member or a different material. Alternatively, the holding force in the rotating direction may be adjusted. Further, in the present embodiment, the forward / backward restricting engagement piece 23 and the rotation restricting engaging piece 24 are separately provided to perform the forward / backward restriction and the rotation restriction. However, the present invention is not limited to this. By providing the engaging ridge 25 inside the mating piece 24, the engaging ridge 25 is engaged with the projection 42 of the pipe 40 and the engaging ridge 41 is omitted. Is also possible. At this time, by providing the engagement ridge 25 closer to the rear end than the tip of the rotation restricting engagement piece 24, the holding force of the pipe 40 in the advancing / retreating direction by the engagement ridge 25 is held in the rotation direction. Can be stronger than power.

In the present embodiment, the engaging ridge 41 and the projection 42 are provided only at the lower end of the pipe 40. However, the present invention is not limited to this. It is possible to hold the moving direction and the turning direction of the pipe 40.

[0021]

According to the first aspect of the present invention, as described above, the water discharge height and the water discharge direction can be adjusted at the time of use with a simple structure. Obtainable. In addition, the manufacturing cost of such a spout stand can be reduced. Claim 2
According to the invention described in (1), the water discharging device stand according to (1), which holds the support rod in the holder so as to be able to advance and retreat, can have a simple structure to facilitate maintenance, and the manufacturing process thereof can be simplified. According to the third aspect of the present invention, in addition to the above effects, even when the number of projections provided on the support rod is limited, for example, when the support rod is formed by injection molding, the mold splitting is hindered. In addition, the water discharging direction of the water discharging tool stand can be finely held at a large number of positions equal to or more than the number of projections, and the operability of the water discharging tool stand can be improved.
