Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. FIG. 1 shows a first embodiment of the present invention, in which a drain 1a of a wash bowl 1 has a pop-up stopcock 2, and an operating lever 3 is attached to an overflow hole 1b.

As shown in FIG. 2, the operating lever 3 is fixed to a central portion of the overflow hole 1b through a stay (not shown) in which a mounting plate 4 extends radially, and the central portion of the mounting plate 4 is fixed. An operating lever 3 is provided on the front and back so as to be slidable back and forth. This operating lever 3 has a disk 3a for the knob at the front end.
In addition, the rod 3b is attached to the rear end and is connected to the pop-up water stopcock 2 via the power transmission mechanism 5.

That is, the power transmission mechanism 5 includes three rotary levers 5a, 5b, 5c and two connecting rods 5 connecting them.
d and 5e, the upper rotary lever 5a is attached so as to be rotatable around a pivot pin 5f as a fulcrum,
The rear end of the rod 3b of the operating lever 3 is pivotally supported at one end thereof, and the upper end of the connecting rod 5d is pivotally supported at the other end thereof. The rotary lever 5b in the middle is
The pivot pin 5g is attached so as to be rotatable about a fulcrum, and the lower end of the connecting rod 5d is pivotally supported at one end thereof, and the rear end of the connecting rod 5e is pivotally supported at the other end thereof. ing. The lower rotary lever 5c is a pivot pin 5h.
Is attached so that it can rotate about a fulcrum, the front end of the connecting rod 5e is pivotally supported at one end thereof, and the lower end of the rod 2a attached to the pop-up water stop 2 is at the other end. It is pivotally supported.

Therefore, from the state shown in FIG.
When is pressed, the upper rotary lever 5a rotates clockwise to push down the connecting rod 5d, and the connecting rod 5d also rotates the intermediate rotary lever 5b clockwise to advance the connecting rod 5e. 5, the lower rotary lever 5c rotates in the clockwise direction to push up the rod 2a, and the pop-up stopcock 2 rises to open the drainage port 1a. In this state, the hot water W stored in the wash bowl 1 can be drained.

On the contrary, when the operation lever 3 is pulled, the pop-up type water stopper 2 is pulled and descends as shown in FIG. 2, and the drain port 1a is closed, so that hot and cold water can be stored in the wash bowl 1. .. However, in this case, since the vicinity of the overflow hole 1b is exaggeratedly drawn large, the water level of the hot water W stored in the wash bowl 1 is actually higher.

FIG. 3 shows a second embodiment of the present invention. The basic structure is the same as that of the first embodiment, and the drain 12a of the washbasin 12 has a pop-up type stopcock 22 and the overflow hole 12 is provided.
The operation lever 32 is attached to b.
The mounting plate 42 is fixed to the center of the overflow hole 12b via a stay (not shown) that extends radially, and the operation lever 32 is provided at the center of the mounting plate 42 so as to be slidable back and forth. ing. The operating lever 32 has a disc 32a at the front end, a rod 32b at the rear end, and is connected to the pop-up stopcock 22 via a power transmission mechanism 52.

In this case, the difference from the first embodiment is that the disk 32a of the operating lever 32 is formed to have substantially the same size as the overflow hole 12b, and the overflow hole 12b is completely closed during drainage as shown in FIG. Is to be done. Therefore, small objects such as contact lenses are not lost from the overflow hole 12b during drainage. Even if the overflow hole 12b is closed, the drainage port 12a is open, so there is no problem in draining.

Further, when the water is drained, the disk 32a of the operating lever 32 and the side wall of the wash bowl 12 are flush with each other, so that no injury is caused by catching a hand or a finger, and the design is excellent. .. In this case, since the operation lever 32 cannot be pulled, the pop-up type stopcock 22 may be pushed down to close the drain port 12a. When the drain port 12a is closed, the disk 32a of the operating lever 32 is in a protruding state, so the overflow hole 12b is in a non-closed state and functions as an overflow hole. On the contrary, when the operation lever 32 is pushed in, the pop-up type stopcock
22 rises and becomes drained. Furthermore, although the side walls of the operating lever 32 and the wash bowl 12 are not flush with each other,
If a protrusion for a knob is provided on 32, the pop-up type stop cock 22 can be moved up and down only with the operation lever 32.
