Description

DETAILED DESCRIPTION OF THE INVENTION "Object of Invention" (Field of Industrial Application) The present invention relates to a structure for adjusting a holding posture (height and swing direction) of a shower head in a hand shower.

(Prior Art) FIG. 3 is a perspective view showing a conventional hand shower 1. The hand shower 1 is configured such that the holding posture of the shower head 4 can be adjusted according to the height difference of the user or the usage mode. That is, the guide bar 2 is installed along the longitudinal direction of the wall surface in the bathroom, etc., and the hanger member 3 for sealing the shower head 4 is slidably inserted into the guide bar 2. It was Then, on the hanger member 3, on its side surface (or front surface),
A bolt 3a with a handle for pressing the outer peripheral surface of the guide bar 2 was screwed. Therefore, the hanger member 3 can be slid along the axial direction of the guide bar 2 and rotated along the outer peripheral direction of the guide bar 2 by loosening the screwing degree of the bolt 3a with a handle (hereinafter, the hanger member 3 can be slid When the bolt 3a with a handle is fully tightened until it comes into contact with the guide bar 2, the stopped state can be maintained.

(Problems to be Solved by the Invention) The conventional hand shower 1 is provided on the outer peripheral surface of the guide bar 2.
The guide bar 2 is provided with pressure contact scratches, scratches, etc. due to the bolt tip (not shown) of the handle bolt 3a.
As the number of sliding times of the hanger member 3 with respect to the number of times increased, the number of scratches and the depth of scratches also increased. These scratches cause rust and deteriorate the appearance of the guide bar 2,
Moreover, the sliding of the hanger member 3 with respect to the guide bar 2 is made heavy. Further, when the bolt 3a with a handle is excessively tightened with respect to the hanger member 3, the pressure-contact damage attached to the guide bar 2 is accompanied by swelling around the wound periphery, and the hanger member is attached to the guide bar 2. 3 was unable to slide.

The present invention has been made in view of the above circumstances, and when adjusting the holding posture of the shower head, prevents scratches from being formed on the outer peripheral surface of the guide bar for a long period of time. It is an object of the present invention to provide a novel posture holding structure (hereinafter, referred to as a main structure) of a shower head in a hand shower in which the appearance of the guide bar is maintained and the holding posture of the shower head can be adjusted smoothly and lightly. .

"Construction of device" (Means for solving the problem) The gist of the structure of the present invention is that a guide bar is vertically installed on a wall surface in a bathroom and a grip slidably inserted into the guide bar. The holding cylinder and the shower holding cylinder are in a female and male screwing relationship with each other along the axial direction of the guide bar, and the male screw end portion is provided in the cylinder provided with the male screw. A stop tongue that can come into contact with the outer peripheral surface of the guide bar is projectingly provided at the screwing tip end of the male screw side cylinder at the screwing rear end of the female screw end portion of the cylinder provided with the female screw. The point is that an inclined pressing surface that can contact the tongue is formed.

(Operation) The grip cylinder is a cylinder body whose outer peripheral surface is formed so as to be easily gripped, or which is provided with a handle or the like. On the other hand, the shower cylinder is a cylinder provided with a hanger portion that hooks the shower head. Both of the gripping cylinder and the shower cylinder are configured such that their respective cylindrical holes are inserted into the guide bar, and a female hole is formed around the outer peripheral surface of the guide bar.
It is designed to screw together in a male relationship. Therefore, one of the cylinders is formed with a female screw end portion, and the other cylinder is formed with a male screw end portion.

In the state where both cylinders are not screwed or the screwing degree is loose even if they are screwed, the stop tongue provided at the screwing tip of the male screw end is attached to the outer peripheral surface of the guide bar. Not in contact. At this time, both cylinders, that is, both the gripping cylinder and the shower cylinder are freely slidable along the axial direction of the guide bar and rotatable along the outer peripheral surface. However, when both cylinders are screwed to each other and both are rotated so that the degree of screwing is increased, the inclined pressing surface provided at the screwing rear end of the male screw end and the male screw end And the stop tongues come into contact with each other, and the stop tongues are strongly pressed against the outer peripheral surface of the guide bar. If the pressing force that presses the outer peripheral surface of the guide bar is increased, at the same time, the contact area of the stop tongue gradually increases in the circumferential direction or the entire circumference. It will not be established. In this way, the gripping cylinder has a strong braking action on the guide bar and a strong screwed state with respect to the shower holding cylinder, so that the posture of the shower head hooked on the shower holding cylinder is maintained.

(Embodiment) The present invention will be described below with reference to the drawings showing an embodiment thereof.

FIG. 1 is a perspective view showing a hand shower 5 having the structure of the present invention. In the structure of the present invention, a grip cylinder 6 and a shower holding cylinder 7 are slidably inserted into a guide bar 2.

The grip cylinder 6 is a vertically long cylinder having an outer diameter that makes it easy to grip and has a hollow inside (described later), and has a semi-spherical projection 6b, 6b, ... Are formed. Further, the shower holding cylinder 7 is a vertically short cylindrical body, and a hanger portion 8 for hooking the shower head 9 is projectingly provided to the side thereof. FIG. 2 is a partial front sectional view showing the grip cylinder 6 and the shower holding cylinder 7 in a disassembled state. A cylinder hole 6a formed in the grip cylinder 6 and a cylinder hole 7a formed in the shower holding cylinder 7
In each case, the inner diameter thereof is formed to be slightly larger than the outer diameter of the guide bar 2 (shown by the chain double-dashed line).

At the upper end of the grip cylinder 6, a male screw end portion 10 having a male screw engraved on the outer peripheral surface thereof is formed. Further, a stop tongue piece 12 is projectingly provided at a screwing forward end portion (upper portion in the drawing) of the male screw end portion 10. The stop tongue piece 12 is formed like a short cylinder having a thin shell portion, and has elasticity necessary for reducing the diameter and restoring the diameter. Although not shown, in order to easily obtain elasticity in the stop tongue piece 12, a plurality of slits are bored in the radial direction of the short tube portion and the short tube portion is divided into a plurality of arc pieces. do it. The inner diameter of the cylindrical hole of the stop tongue piece 12 is formed to be slightly larger than the outer diameter of the guide bar 2, and the outer diameter of the cylinder is formed to be one step smaller than the outer diameter of the male screw end portion 10. There is. A reinforcing rib 12a having a hemispherical cross section is provided around the outer peripheral surface of the tip of the stop tongue 12.

The lower end portion of the shower holding cylinder 7 is a female screw end portion 11 in which a female screw is engraved on the inner peripheral surface of the cylindrical hole 7a. The female screw end portion 11 corresponds to the male screw end portion 10 of the grip barrel 6 and enables the shower holding barrel 7 and the grip barrel 6 to be screwed together. On the inner surface of the shower holding cylinder 7, an inclined pressing surface 13 is formed on the screwing rear end portion (upper portion in the figure) of the female screw end portion 11 about half the circumference thereof. The inclined pressing surface 13 has an inclination so as to smoothly connect the inner diameter of the female screw end 11 and the outer diameter of the guide bar 2. In the inner surface of the shower holding cylinder 7, the area where the inclined pressing surface 13 is formed is
It can be appropriately selected from the portion occupying four circles or the entire circumference.

It is assumed that the gripping cylinder 6 and the shower holding cylinder 7 are inserted into the guide bar 2 and the both cylinders 6 and 7 are screwed together. When the degree of screwing of the two is loose, the stop tongue 12 of the gripping cylinder 6 and the inclined pressing surface 13 of the shower holding cylinder 7 are not yet in contact with each other, so that the stop tongue 12 of the gripping cylinder 6 is also a guide bar. 2 is not in contact with the outer peripheral surface. Therefore, the gripping cylinder 6 and the shower holding cylinder 7 are kept in a loose fitting connection state with each other,
It is in a state where it can be freely moved up and down and rotated with respect to the guide bar 2. Therefore, the posture (height and swinging direction) of the shower head 9 (see FIG. 1) hooked on the hanger portion 8 of the shower holding cylinder 7 can be adjusted to a desired state. After adjusting the posture of the shower head 9,
The gripping cylinder 6 is rotated with respect to the shower holding cylinder 7 to increase the screwing degree of both. As a result, the grip cylinder 6
The stop tongue 12 is reduced in diameter while being in contact with the inner surface side of the inclined pressing surface 13 of the shower holding cylinder 7, and is press-fitted into the shower holding cylinder 7 to strongly adhere to the outer peripheral surface of the guide bar 2. It is pressed. Therefore, the grip cylinder 6 exerts a strong braking action on the guide bar 2, and the shower holding cylinder 7 is firmly screwed to the grip cylinder 6, so that the shower head 9 is not adjusted. Posture is maintained.

(Study of Another Mode) The vertical positional relationship between the grip cylinder 6 and the shower holding cylinder 7 may be opposite to that in the above-described embodiment. Further, the grip cylinder 6 may be provided with the female screw end portion 11 and the shower holding cylinder 7 may be provided with the male screw end portion 10. Further, the stop tongue piece 12 provided on the male screw end portion 10 does not need to be the entire peripheral portion with respect to the male screw end portion 10, and may be a part thereof. Therefore, the inclined pressing surface 13 provided on the female screw end portion 11 may be provided only in a partial area where the stop tongue piece 12 can be pressed. In the case of adopting such a structure, in the male screw end portion 10 and the female screw end portion 11, the shower pitch of the shower holding cylinder 7 can be increased by roughening the mutual screw pitch or using a multiple thread screw.
It is more convenient to reduce the amount of rotation of the grip cylinder 6 with respect to. As described above, the configuration and shape of the structure of the present invention can be appropriately changed according to the embodiment.

[Advantage of Device] As is clear from the above description, the posture maintaining structure of the hand shower according to the present invention increases the pressing force for pressing the outer peripheral surface of the guide bar and, at the same time, increases the contact area of the pressing force. But,
It is designed to gradually expand in the circumferential direction or the entire circumference. In the conventional hand shower, the bolt with a handle that never increases the contact area is pressed linearly in the radial direction against the outer peripheral surface of the guide bar. As a result, the surface pressure has been increasing. However, since the structure of the present invention is completely different from such a pressing action, the outer peripheral surface of the guide bar is not scratched. Therefore, rust does not occur on the guide bar, the appearance of the guide bar is maintained for a long period of time, and the holding posture of the shower head can be adjusted smoothly and lightly. Of course, the outer peripheral surface of the guide bar does not bulge locally, so that the holding posture of the shower head cannot be adjusted.

Further, unlike the conventional hand shower, since the handle does not protrude to the side surface or the front surface of the hanger portion that holds the shower head, it has a number of excellent advantages such as a neat appearance overall. is doing.
