DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shower head support device.

[0002]

2. Description of the Related Art In recent years, a wash basin or a sink provided with a shower head connected to a faucet such as hot water using a flexible tube such as a hose has been widely used. In this type of wash basin or the like, a support device provided with an accommodation support portion for accommodating the base end portion of the shower head so as to be able to be inserted and removed with the flexible tube inserted is often used.

[0003]

However, in this supporting device, when the shower head is pulled out from the device and used, water adheres to the flexible tube due to splashing of water in a shower or the like.
There is a possibility that the water may enter the main body of the device through the flexible tube. In particular, in the case where the projecting end of the housing support is open, the water jumping from this opening bounces off the inner surface of the housing support and easily adheres to the flexible tube, so that the amount of water transmitted through the flexible tube is reduced. The risk of water intrusion has increased.

On the other hand, it is conceivable to prevent the intrusion of water by providing a drainage portion such as a packing inside the accommodation support portion and making the outer peripheral surface of the flexible tube closely contact the inner peripheral surface of the drainage portion. Can be However, in this case, it is difficult to move the flexible tube smoothly due to the influence of the friction between the drain portion and the flexible tube, which tends to hinder a smooth insertion / removal operation of the shower head. For this reason, making the outer peripheral surface of the flexible tube and the inner peripheral surface of the draining section completely intimately involves such an adverse effect. Therefore, in the case of using such a drain portion, it is necessary to secure a certain gap between the outer peripheral surface of the flexible tube and the inner peripheral surface of the drain portion,
In reality, it is impossible to completely prevent water from entering the inside of the main body of the support device.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a shower head capable of effectively preventing the intrusion of water flowing through a flexible tube into a main body of a support device while enabling a smooth insertion and removal operation of a shower head. It is an object of the present invention to provide a supporting device.

[0006]

According to a first aspect of the present invention, there is provided a shower head support device (hereinafter, referred to as a "support device") having a substantially cylindrical shape of a shower head connected to a predetermined faucet via a flexible tube. A support portion for projecting the flexible tube in a state in which the flexible tube is inserted through the housing support portion protruding in a substantially cylindrical shape, wherein the flexible tube is slidably inserted. A substantially cylindrical inner bush having a hollow portion is provided inside the housing support portion so as to protrude in substantially the same direction as the direction in which the housing support portion protrudes.

[0007] In the present invention, the inner bush protrudes into the accommodating and supporting portion, and the flexible tube is inserted through the inner bush. For this reason, when the shower head is pulled out of the apparatus and used, the water that bounces off the inner surface of the storage support portion is blocked by the inner bush and does not adhere to the flexible tube. Further, water adhering to the flexible tube on the shower head side with respect to the accommodation support portion is drained at the tip of the inner bush, and is easily separated from the flexible tube. Therefore, it is possible to eliminate or reduce water that is going to enter the inside of the main body of the apparatus through the flexible tube.

[0008] The inner bush has a hollow portion through which the flexible tube can be slidably inserted. Moreover, since the inner bush has a substantially cylindrical outer shape, the entire length of the hollow portion can be made larger than the entire length of the hollow portion of the packing conventionally used as the drainage portion. Therefore, the flexible tube is guided by a hollow part having a sufficient length, and can move smoothly in this hollow part. Therefore, even if this inner bush is used, the shower head can be smoothly inserted and removed.
The inner bush is made of resin, metal, etc.
Moreover, when the inner peripheral surface of the hollow portion is made smooth, the flexible tube can move more smoothly through the hollow portion.

According to a second aspect of the present invention, there is provided the support device of the first aspect, wherein one or more drain holes are provided on a lower surface side of the inner bush. The present invention is intended to more reliably achieve the function of the support device of the first aspect of the present invention. That is, even if a small amount of water enters between the inner bush and the flexible tube, the water can be smoothly discharged to the outside of the drain hole. In particular, if the drain hole is provided closer to the end of the inner bush (inside the main body of the apparatus), the water intrusion path can be lengthened, the flow velocity of the water can be reduced, and the drain from the drain hole can be more easily drained. It can be performed reliably.
