Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a faucet device, and more particularly to a device having a feature in a mounting structure to a mounting base such as a counter.
[0002]
[Prior art and problems to be solved by the invention]
Conventionally, when the faucet device is attached to an attachment base such as a counter or a basin, the faucet body is directly attached to the upper surface (attachment surface) of the attachment base.
[0003]
By the way, in the case of a conventional faucet device, the spout water operation unit is originally used in spite of the fact that the position of the spout water operation unit and spout of the faucet device varies depending on the faucet user. And the position of the water outlet are automatically determined at a certain position depending on the type of the faucet device.
In this case, if it is a normal healthy person, even if the position of a spout water operation part, a spout, etc. have shifted | deviated from the position appropriate for the person, a faucet device can be especially used without trouble.
[0004]
However, especially in the case of a person with a physical disability, for example, a person who is forced to use a faucet while sitting in a wheelchair, or that the faucet is stretched without bending down because of a backache. For a person who has to use it, conventionally, the position of the water discharge operation part or the water discharge port of the faucet device is extremely difficult to operate or use.
That is, the conventional faucet device is difficult to use for those people.
[0005]
In this case, in order to make the faucet device easy to use, it is necessary to remove the faucet device already installed and install another special faucet device.
However, there is not always such a special faucet device, and if this is specially prepared, the cost for manufacturing the faucet device will increase, and a great variety of faucet devices will be prepared in advance. In practice, it is practically difficult to do.
[0006]
However, Patent Document 1 below also proposes a technique in which a pedestal is interposed between the faucet body and the mounting base so that the positions of the water discharge operation portion and the water discharge port can be adjusted to be high.
[0007]
FIG. 5 shows a specific example of the faucet device.
In the figure, reference numeral 200 denotes a pedestal inserted between the faucet body 202 and a basin 204 as an attachment base.
Reference numeral 206 denotes a single lever type spouting operation section provided on the upper part of the faucet body 202, and 208 denotes a water outlet at the tip of the water discharge pipe extending from the faucet body 202.
[0008]
However, in the faucet device disclosed in Patent Document 1, the height position of the spout 208 is set depending on whether the counter is attached so as to cover the upper surface of the basin 204 or when such a counter is not attached. Therefore, in the case of this faucet device, the height positions of the water outlet 208 and the water stop operation portion 206 only change between two positions. In this case, once installed, the faucet user cannot adjust the positions of the water discharge port 208, the water discharge operation unit 206, and the like thereafter.
[0009]
However, the following Patent Documents 2 and 3 disclose that the positions of the water discharge port and the water discharge operation unit can be adjusted after the faucet device is installed.
However, in the case of the faucet devices disclosed in these Patent Documents 2 and 3, the piping for supplying water to the faucet body is exposed to the outside, giving a complicated appearance, and also in terms of aesthetics. It was insufficient.
