[Problems to be solved by the invention]
In the water spout stand described above, since a stopper is formed in the joint pipe in advance at a position corresponding to the assumed lift amount, in order to set an appropriate lift amount according to the situation where the water spout stand is installed. In addition, it is necessary to manufacture joint pipes in which the stoppers are formed at different positions, which increases the manufacturing cost of the water spout stand. In addition, since a stopper is formed in the joint pipe in advance, there is also a problem that it is not possible to adjust or change the lift amount at the construction site.
[0005]
The present invention solves the above-mentioned problems of the conventional water spout stand, and provides a spout stand with low manufacturing cost by enabling joint pipes of various lifts to be manufactured with the same mold. The purpose is to: It is another object of the present invention to provide a water spout stand capable of adjusting and changing a lift amount at a construction site.
[0006]
[Means for Solving the Problems]
Means taken by each of the present invention to solve the above problems will be described below. The water spout stand of the present invention is a water spout stand comprising: a joint pipe on which a water spout is supported on the distal end side; and a holder that slidably inserts the joint pipe in the axial direction of the joint pipe. The outer peripheral surface near the lower end of the joint pipe is provided with two or more locking concave parts provided at different positions in the axial direction of the joint pipe, and is fitted into any one of the locking concave parts to form the holder. The lower end surface is provided with a locking piece which can be locked (claim 1).
[0007]
In the spout stand in which the joint pipe is slid in the axial direction to change the position of the spout, the joint pipe can be locked at two or more different positions so that the installation state of the spout stand can be improved. Accordingly, the lift amount of the joint pipe can be changed. Here, the “locking recess” and the “locking piece” are not particularly limited as long as the “locking piece” is fitted into the “locking recess” so that the “locking piece” can be locked to the lower end surface of the holder. However, for example, as the "locking recess", a plurality of circumferential grooves are provided on the outer peripheral surface of the joint pipe, and as one of these circumferential grooves, a "locking piece" formed to have a diameter larger than the inner diameter of the lower end surface of the holder. Can be exemplified.
[0008]
Further, another water discharging device stand of the present invention is a water discharging device comprising: a joint pipe on which a water discharging device is supported on a distal end side; and a holder that slidably penetrates the joint tube in the axial direction of the joint tube. A stand, provided on the outer peripheral surface of a lower end of the joint pipe, a locking convex portion that can be locked to a lower end of the holder, and an outer peripheral surface closer to a lower end above the locking convex portion, One or more locking recesses into which locking pieces that can be locked can be fitted are provided at the lower end of the holder, and the locking convex portions and the locking recesses are respectively located at different positions in the axial direction of the joint pipe. It is characterized by being provided (claim 2).
[0009]
In the present invention, the joint pipe can be provided to be able to be locked at two or more different places similarly to the above, and the lift amount of the joint pipe can be changed according to the installation state of the water discharging tool stand. When the largest lift amount is set, the lower end of the holder is locked by the lowermost locking projection of the joint pipe without fitting the locking piece to the locking recess. When setting a small lift amount, the lift amount can be adjusted by fitting a locking piece into the locking concave portion above the locking convex portion. Therefore, by setting the lift amount when the lower end of the holder is locked to the locking convex portion as the initially set lift amount, the locking piece is unnecessary unless the lift amount is changed from the initially set lift amount. be able to. Therefore, when the possibility of changing the lift amount is not high, the number of parts can be reduced without attaching a locking piece to the water discharging tool stand at first.
[0010]
Further, the above-mentioned locking piece can be provided detachably with respect to the joint pipe (claim 2). With this configuration, the locking piece once fitted in the locking recess can be attached to another locking recess, so the lift amount can be adjusted at the construction site of the water spout stand, or renewed after construction. The lift amount can be changed.

[0020]
As shown in FIGS. 5 and 6, when the water discharging tool holder 14 is pulled up, the C-ring 52 fitted in the circumferential groove 50 of the joint pipe 16 engages with the lower end surface 27 of the holder 18 and the protrusion. Engagement with the groove 21 of the piece 23 prevents further movement of the water spout holder 14 and the joint pipe 16 upward, thereby preventing the joint pipe 16 from coming off. The lower end surface 27 of the holder 18 and the upper end of the groove 21 are provided at the same position in the axial direction of the holder 18.
[0021]
As described above, the outer diameter of the C ring 52 as shown in FIG. 8 is formed to be larger than the inner diameter of the lower end surface 27 of the holder 18 shown in FIG. 7, and when the joint pipe 16 is pulled upward, , The upper part of the C-ring 52 is securely locked to the lower end face 27 of the holder 18, so that the further movement of the joint pipe 16 can be reliably restricted. Further, by fitting the C-ring 52, the C-ring 52 can be locked to the C-ring 52 over substantially the entire periphery of the lower end surface 27 of the holder 18, and the regulation can be performed reliably and stably. At the same time, the C-ring 52 is fitted in the groove 21 of the protruding piece 23, and the movement of the joint pipe 16 is more reliably restricted.
[0022]
When the water discharging tool holder 14 and the joint pipe 16 are pulled up, immediately before the C-ring 52 comes into contact with the lower end face 27 of the holder 18, first, the lower end face of the projecting piece 23 comes into contact with the upper part of the C-ring 52 and is kept constant. Give resistance. Further, in the case of being pulled up by a predetermined force or more, the projecting piece 23 gets over the C-ring 52 while bending outward of the holder 18. Therefore, the projecting piece 23 in which the groove 21 is formed prevents the water discharge tool holder 14 and the joint pipe 16 from coming off together with the lower end surface 27 of the holder 18, and the water discharge tool holder 14 and the joint pipe 16 are finally regulated. Immediately before the lifting operation, an appropriate resistance is given to the lifting operation of the water discharging tool holder 14 and the joint pipe 16 so that the lifting operation is not stopped suddenly, thereby improving the operational feeling at the time of the lifting operation.
[0023]
Further, when the water discharging tool holder 14 and the joint pipe 16 are further pulled up, the C ring 52 is brought into contact with the lower end surface 27 of the holder 18 to stop the lifting operation, and the C ring 52 is fitted into the groove 21 so that the joint pipe is fitted. 16 is locked. Therefore, the height of the water spout holder 14 and the joint pipe 16 can be temporarily held during the maximum lift of the water spout holder 14 and the joint pipe 16 appropriately determined by the fitting position of the C-ring 52, and this lifting can be performed. The water can be discharged from the shower head 12 supported by the water discharging tool holder 14 in the state where the water is discharged. When it is desired to pull down the water spout holder 14 and the joint pipe 16 downward, if a predetermined force or more is applied to the water spout holder 14 or the joint pipe 16 against the resilient force of the projecting piece 23, the C ring The fitting state between the groove 52 and the groove 21 is released, and the water discharging tool holder 14 and the joint pipe 16 can be pulled down. Since the fitted state of the C-ring 52 and the groove 21 does not come off unless a predetermined force or more is applied, there is no possibility that the water discharging tool holder 14 and the joint pipe 16 are lowered by their own weight.
[0024]
The C-ring 52 is detachably fitted to the circumferential groove 50, and the C-ring 52 can be fitted to each of the circumferential grooves 50 of the joint pipe 16. Depending on whether the C ring 52 is attached to the groove 50, the lift amount of the water spout holder 14 can be set in five stages in the same joint pipe 16. In addition, since the C-ring 52 can be removed from the circumferential groove 50, the lift amount can be changed as necessary even after the water spout stand 10 is once installed. When the water discharging tool holder 14 is pulled down, the lower end surface of the water discharging tool holder 14 abuts on the cover 40 to restrict the downward movement of the water discharging tool holder 14. The number of the circumferential grooves 50 is not limited to five, but may be another number as long as it is two or more. The above embodiment is an example in which the C-ring 52 fitted in the circumferential groove 50 of the joint can 16 is engaged with the lower end surface 27 of the holder 18 and the groove 21 of the protruding piece 23. The C-ring 52 fitted in the peripheral groove 50 may be configured to engage with the groove of the projecting piece 23 without contacting the lower end surface 27 of the holder 18.
[0025]
Next, a joint pipe according to another embodiment will be described with reference to FIG. As shown in FIG. 9, a convex ridge 54 as a locking convex portion is provided on the outer peripheral surface of the lower end of the joint pipe 16, and three peripheral grooves 50 are provided above the convex ridge 54. The outer diameter of the ridge 54 is formed with the same size as the outer diameter of the C ring 52, and the width of the ridge 54 is formed with the same size as the thickness of the C ring 52. In this example, since the ridge 54 can be used as the locking piece in the above embodiment, the number of parts can be reduced. When it is desired to change the lift amount to a small value, the desired lift amount can be changed by fitting the C-ring 52 into one of the circumferential grooves. It is sufficient that the locking convex portion can be locked to the lower end of the holder, and it is not necessary to be the above-mentioned convex ridge, and it may be a projection.
[0026]
The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the claims. For example, a plurality of substantially parallel recesses having a so-called two-plane width may be formed on the outer peripheral surface of the joint pipe 16 and a clip that can be fitted thereto may be attached thereto. In addition, instead of forming the peripheral groove 50 as described above, simply forming a groove, a concave portion or a hole, and engaging the locking piece of various shapes to be locked to the lower end surface 27 of the holder 18. May be fitted. Examples of the locking piece include a rubber O-ring, a C-shaped concentric retaining ring, and an E-shaped retaining ring in addition to the C-ring.
