DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remotely operated drain cock opening / closing device for a water tub such as a bath tub, and more particularly to a remote operated drain cock opening / closing member at a drain port of a water tub. The present invention relates to a stopper opening and closing device.

[0002]

2. Description of the Related Art Various types of devices for opening and closing a drain plug of a water tank by remote control have been known as disclosed in Japanese Utility Model Publication No. Sho 60-22147 and Japanese Utility Model Publication No. Hei 7-38420. ing. As described in detail in these publications, a remotely operated drain cock opening and closing device for an aquarium includes a drain cock attached to a drain port portion of the aquarium,
It consists of a remote control unit attached to the flange part of the water tank, and an operation wire wired between the drain plug unit and the remote control unit, and after attaching these parts to the water tank,
By operating a push button (operation button) of the remote control unit, the plug of the drain plug unit is opened and closed.

The operation of mounting the remote-operated drain cock opening / closing device on a water tank will be briefly described with reference to FIG. 11. First, a hole 3 formed in a flange portion 2 of a water tank, for example, a bathtub 1 will be described.
The tubular casing 5 is inserted through the packing 4 and fastened with the round nut 6 from the back side of the flange portion 2, and then the conduit 7 and the tubular casing 5 are connected to form an operating section (procedure 1). .

[0004] Next, the operation wire 8 is inserted from the cylindrical casing 5, and the leading end thereof is positioned at the center of the drain pipe elbow 9 connected to the rear end of the conduit 7 through the conduit 7 (procedure 2). As is well known, the operation wire 8 is formed by inserting a core wire 10 such as a piano wire into a flexible tube by being resiliently urged toward the remote control unit side, and the core end portion 11 is provided at the distal end of the tube. A predetermined length protrudes from the mounting screw 12.

Subsequently, the drainage pipe 14 is screwed into the opening of the drainage pipe elbow 9 through the packings 13, 13, and the drainage pipe 14 and the drainage pipe elbow 9 are attached to the drainage port 15 of the bathtub 1 (step 3). ).

When the drain pipe 14 and the drain pipe elbow 9 have been mounted on the drain port 15 of the bathtub 1, the end of the operation wire 8 located in the drain pipe elbow 9 is connected to a small transparent pipe at the center of the drain pipe 14. Using a tool such as lead pliers, pinch it out of the hole and pull it up (step 4).

Next, the mounting screw 12 at the end of the operation wire 8 pulled up through the through hole of the drainage cylinder 14 and the screw hole at the lower part of the guide cylinder 16 are screwed together, and the core end 11 of the operation wire 8 is inserted into the guide cylinder 16. After that, the guide tube 16 is fitted into the through hole provided at the center of the drainage tube 14, and the guide tube 16 is turned to set it in the unextracted state (step 5).

Subsequently, the shaft 18 of the stopper 17 is inserted into a guide hole formed in the center of the guide tube 16, and the shaft 1
The core wire end 1 of the operation wire 8 is provided on the lower surface of a small disk disposed at the lower end of the buffer spring contained in
1 is brought into contact with the drain plug part (step 6).

Thereafter, a push button 19 is fitted into the tubular casing 5 of the remote control unit, and the upper end of the core wire of the operation wire 8 located in the tubular casing 5 is fitted to the push button 19. The lower end of the shaft 20 to be engaged is engaged, and the push button 19 is operated so that the core wire 10 in the wire 8 moves forward and backward to open and close the plug 17 of the drain plug (step 7). .

In this manner, the remote-operated drain cock opening / closing device is attached to the bathtub 1 and the push button 19 of the operating part is located at the top of the tubular casing 5 by the stopper 17 of the drain cock. When the drain port 15 of the bathtub 1 is closed and the push button 19 is pressed down, the stopper 17 of the drain plug is lifted by the core end 11 of the operation wire 8 to open the drain port 15 of the bathtub 1. Things.

[0011]

However, when the above-mentioned conventional remote-operated drain cock opening / closing device is mounted on the bathtub, a drain pipe 14 and a drain pipe are inserted into the drain port 15 of the bathtub 1 as described in "Procedure 4". After attaching the elbow 9, the distal end of the operation wire 8 positioned in the drain pipe elbow 9 is picked up from a small through hole in the center of the drainage cylinder 14 using a tool such as lead pliers, and further pulled up. As in “Procedure 5”, the end of the operation wire 8 pulled up through the through hole of the drainage cylinder 14 is screwed and connected to the lower part of the guide cylinder 16, and then the guide cylinder 16 is moved to the center of the drainage cylinder 14. A complicated operation of fitting into the provided through-hole and rotating the guide cylinder 16 to set it in the unextracted state must be performed.

In addition, in particular, the work of the above “Procedure 4”
Since there is not enough lighting and the robot is in an unrestricted posture and requires fine movements, much time and labor is required, and the end of the operation wire 8 is screwed into the lower part of the guide tube 16 as in “Procedure 5”. When the guide cylinder 16 is moved in the state of being connected in a connected state, bending or twisting is applied to the core wire 11 that moves forward and backward, and the inconvenience that the forward and backward movement of the core wire 11 is not smooth occurs.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a remote-operated drain plug opening / closing device for a water tank in which the above disadvantages are solved and a drain plug can be mounted with good workability.

[0014]

The present invention has solved the above-mentioned problem by fixing a holder for erecting an operation wire in a drain pipe elbow provided below a drain opening of a water tank. is there. That is, the remote control type drain cock opening / closing device for the water tank of the present invention is configured such that the core wire of the operation wire is advanced and retracted by opening / closing operation of the operation button of the remote control unit to open / close the water drain plug cap. The operation wire can be fitted tightly into the drain pipe elbow connected to the lower part of the drain port of the water tank in the drainage cock opening and closing device.
It has a hole and communicates with the hole on the side.
A holder with an opening with a slightly smaller width is fixed,
With this holder, it is set toward the center of the drain port of the aquarium.
The distal end of the operation wire extending from the operation unit held at the position is located at the lower end of the shaft of the stopper with the drain port closed, and the tip of the core end engages the stopper shaft. It is characterized by having been done.

There is no particular limitation on the shape of the holder provided in the drain pipe elbow portion. However, since the drain pipe elbow is often formed of plastic, it can be integrally formed of plastic. Alternatively, a member formed of plastic may be adhered. Basically, a hole for tightly fitting the operation wire is provided at the center portion for holding the operation wire, and the side surface is larger than the inner diameter of the hole. It is preferable to use a short pillar shape that can hold the operation wire provided with an opening groove for inserting an operation wire having a slightly smaller width.

The height of the holder is determined in accordance with the position of the lower end of the guide shaft of the stopper, which is inserted into the center of the drain cylinder screwed into the drain opening of the drain pipe elbow. It is preferable that the end of the core wire of the operation wire that is held upright toward the center of the drain port of the water tank contacts the lower end of the guide shaft of the stopper that is fitted into the center of the drain cylinder.
