An opening / closing operation unit 5 having a locking mechanism 16, a connecting rod 6 connecting the opening / closing operation unit 5 and the drain plug 1 and inserted into the overflow pipe 2, and a cylindrical shape having the drain plug 1 fixed to the upper end. a support shaft coil spring 8 buffer was fitted into the 7 and the spring receiving washer 9, inserted through the connecting rod 6, the tip 10 inserted through the bottom of <br/> support shaft 7 of the drain plug ' Is connected to the back surface of the washer 9, and the other end is connected to the opening / closing operation section 5.
And a wire 10 connected to the support shaft 17 of the operation button 5 ' .

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a remote-operated drain plug 1 is attached to and detached from an upper surface of a cylindrical drain plug 11 fitted to a drain port b. A cylindrical support shaft 7 vertically extending from the center of the back surface is fitted in a support tube 12 fixed vertically at the center so as to be able to move up and down. A coil spring 8 for buffering and a spring receiving washer 9 are fitted in the support shaft 7, and a wire 10 inserted through a hole 13 at the bottom of the support shaft 7.
Is connected to a spring receiving washer 9 in the support shaft 7.

The overflow port 3 attached to the side wall of the bathtub B has a disk-shaped opening / closing operation section 5 provided at the center.
The operation button 5 ′ is pushed in and freely exposed, and an overflow hole 3 ′ is provided around the operation button 5 ′ . The overflow pipe 2 having a tip end hanging down from the back surface of the overflow port 3 connected to the drain pipe 4 has an opening / closing operation unit 5 in which the operation of the opening / closing operation unit 5 is performed.
Is inserted through a flexible connecting rod 6 which slidably penetrates the wire 10 so as to be transmitted.

The drain plug 11 is screwed with a thread portion 14 on the outer periphery of the lower portion from the upper surface of a drain fitting 15, and the overflow pipe 2 is connected to the drain fitting 15 from the side, and both drain pipes pass through the pipe. Is discharged out of the system via a drain pipe 4 connected to the other side.

In the opening / closing device constructed as described above, when the operation button 5 ' of the opening / closing operation section 5 is depressed, the tip 10' of the wire 10 which has moved in the connecting rod 6 passes through the coil spring 8 for buffering. The drain plug 1 is pushed up together with the support shaft 7, but when an object touches the drain plug 1 pushed up on the drain port b during cleaning or the like, the impact of the object or the load caused by the stepping on the person is applied to the coil spring 8. Since it is buffered and added to the wire 10, damage to the equipment and injuries are prevented.

The open state of the drain plug 1 is maintained by the operation of a lock mechanism 16 provided in the opening / closing operation section 5 as described later. In the embodiment shown in FIG.
Is a support shaft connected to the back surface of the operation button 5 'of the opening / closing operation unit 5.
17 and a cylindrical casing 18 through which the support shaft 17 is inserted.
And a cylindrical one-way cam 19 formed on the inner peripheral surface of a casing 18 as shown in FIGS.
And a contact 20 for engaging with the one-way cam 19 and a return spring 21 for the operation button 5 '.

As shown in FIG. 3A, when the operation button 5 'in the closed position of the drain plug is pushed in as shown in FIG. 3B, the wire 10 is pushed to open the drain plug 1, while the one-way cam 19 is opened. One end of the bifurcated contact 20 contacts the protrusion 19a at the bottom of the contact. When the push button operation is released, the support shaft 17 urged by the return spring 21 retreats.
0 is locked by being supported by a hook 19b on one side of the one-way cam 19 as shown in FIG.

When the drain plug 1 is closed, as shown in FIG. 4A, the operation button 5 'is pushed again to the deepest part. At this time, the contact 20 is pushed in while being inclined, and the bottom projection is formed.
The contact 20a comes back in a state with a small inclination, and in the return stroke, one end of the contact 20 comes into contact with the gentle slope portion 19c on the other side of the one-way cam 19 and makes a half turn,
The other end of the contact 20 is returned to the position shown in FIG. 3A without being hooked on the hook 19b, and the drain plug 1 is returned to the closed state by the return movement of the wire 10.

As can be seen with reference to FIGS.
The lock mechanism 16 operates the operation button 5 ′ in the closed state.
Provided so that the work end face is flush with the overflow port 3.
In the open state, it is pushed into the overflow port 3
Operation button 5 '
Do not protrude out of the wall and do not disturb the use of bathtub B
Can be installed.

[0020]

As described above, the opening / closing device of the present invention has a tubular shape in which the distal end of a wire for remote control penetrating through the connecting rod provided in the overflow pipe and the drain plug are fixed to the upper end. having connected to the discharge valve spring receiver provided in the support shaft via the coil spring for buffering the washer, unplugging state odor
In the event that impact or load occurs on the drain plug projecting above the bottom of the bathtub, the coil spring elastically supporting the drain plug buffers and reduces the transmission of load to the wire side. Therefore, the opening / closing mechanism of the drain cock is less likely to be damaged, the durability of the device is increased, and injury can be prevented.

Further, the switchgear of the present invention comprises
Connect the other end to the overflow port on the side wall of the bathtub
Push-button operation button on the opening / closing operation unit provided to
And remote control type drainage with each push operation of the operation button
A lock for alternately holding the stopper between the open position and the closed position.
