Abstract

PROBLEM TO BE SOLVED: To firmly fix a hydrant to a floor in a simple installation work by combining an inner fastening body having a separated end fitted to the outer diametrical part of the hydrant and an outside flange provided with a tapered inner-diametrical face and embracing the inner fastening body in a pipe when fixing it to a floor with wooden screws. SOLUTION: A manipulating structure 3 is positioned above a floor 2 and a valve is positioned at the lower part, in a hydrant. They are connected to each other through a pipe 5. A metallic or resin inner fastening body 13 whose both ends are separated from each other and divided into two halves is laid from the sides of the pipe 5 so as to hold it. The outside flange 12 is forced to pass on the manipulating structure 3 including a handle 15 and put onto the inner fastening body 13 and fasten on the floor 2 with wooden screws 11. In this time, the inner fastening body 13 having a tapered outer-diametrical face 17 widened toward the end and fitted to the tapered inner-diametrical face 16 of the outside flange 12 transfers to the pipe 5 side to embrace the pipe 5 and fasten it. A seal or the like is stuck on the upper face to close the gap of the inner fastening body 13 divided into two halves.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water stopper fixing fixture for fixing a water stopper to a floor.

[0002]

2. Description of the Related Art In the past, many water taps used in cold regions have a valve portion buried deep underground. In such a case, it was not necessary to fix the water tap to the floor. Some types of drain plugs that expose parts under the floor and receive drainage from the hopper and simultaneously discharge hot and cold water have also appeared, and particularly flexible piping such as polyethylene is used for the piping connected to the drain plug. In conjunction with this, it was necessary to fix the drain cock firmly to the floor.

[0003]

SUMMARY OF THE INVENTION In view of the above, it is an object of the present invention to provide a water drainage fixing bracket which can firmly fix a water drainage to a floor and can be easily installed.

[0004]

Therefore, in the present invention, a combination of an inner fastening body having a cut end and an outer flange having a tapered inner diameter surface, which fits into the outer diameter of a drain plug, is used. When installing, insert the internal tightening body from the outside of the pipe, insert the outer flange into the pipe from the top by digging the operation unit structure, and when fixing it to the floor with wood screws, When pressed, the internal tightening member is firmly held by the pipe, so that the drain plug can be fixed to the floor.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A wood screw may be attached to the flange side or to the internal tightening body side. In the former case, the inner diameter surface of the taper of the flange is widened downward, and in the latter case it is attached. Conversely, it expands upward.

[0006] The flange is usually made of metal, but it can also be molded with resin. The internal tightening body may be formed of any one of metal, resin, and rubber. In the case of metal, the both ends are completely separated, and in the case of resin or rubber, only one end is separated. However, it is sufficient to push open the separated part and insert it into the pipe from the side.

The internal tightening member usually has a tapered outer diameter surface which engages with the tapered inner diameter surface. However, it is not necessary to stick to the taper outer diameter surface. I just need.

FIG. 5 shows a schematic view of the apparatus of the present invention.
Reference numeral 1 denotes a water drainage stopper. The operation unit structure 3 is located above the floor 2, and the valve unit 4 is located below the floor 2. Reference numeral 6 denotes a drainage stopper fixture of the present invention, reference numeral 7 denotes a return pipe of water from a water supply device, reference numeral 8 denotes a return pipe of hot water from a hot water supply device, reference numeral 9 denotes a hopper, and reference numeral 10 denotes a drainage pipe.

The figure shows a state in which the hot and cold water in the return pipes 7 and 8 for water and hot water is shut off. When draining the water, the antifreeze water tap provided upstream of the return pipes 7 and 8 is drained. After that, the drain valve 1 may be operated, and the hot and cold water in the return pipes 7 and 8 is discharged from the lower end of the valve section 4 to the hopper 9 and flows to the drain pipe 10.

FIG. 1 is a longitudinal sectional view of an essential part of an embodiment of the present invention, and FIG.
An outer flange 12 is fixed to the floor 2 by the wood screws 11, and a metal or resin-made internal tightening body 13 having both ends cut off and halved is provided with a gap 14 to such an extent that the whole end does not come into contact. The water drain stopper 1 is fixed so as not to move up, down, left and right.

Since the outer diameter of the pipe 5 is slightly different depending on the material and the like, the size of the gap 14 is also changed accordingly, but in any case, in order to improve the appearance, cool air under the floor is introduced into the room. It is desirable that a seal or the like be stuck on the upper surface so as to block the gap 14 so as not to enter.

At the time of installation, first, the half internal tightening member 13 is placed so as to be sandwiched from the side of the pipe 5, and then the outer flange 12 is attached to the operating portion structure 3 including the handle 15.
Is laid on the internal tightening body 13 and tightened to the floor 2 with the wood screw 11, the internal tightening body 13 having the tapered outer surface 17 spreading downward and engaging with the tapered inner surface 16.
Moves to the pipe 5 side, and is hugged and tightened by the pipe 5. Finally, a seal with one end face cut off is stuck on the upper surface, and the operation is completed.

FIG. 3 shows an embodiment in which the inner fastening body 13 is made of rubber or soft resin. One end face is cut off, an appropriate gap 14 is formed, and an arc outer diameter surface 18 is provided. I have. When installing, the gap 14 may be pushed open and inserted from the side of the pipe 5, and if the gap 14 is completely eliminated when tightened by the outer flange 12, it is not necessary to stick a seal on the upper end. Can also be
Costs can be reduced, for example, by reducing material costs and processing time.

In FIG. 4, a wood screw 11 is attached to the half of the internal tightening member 13 side, and a hanging portion 19 projecting into the floor 2 is shown.
In this embodiment, a tapered outer surface 17 is formed to be in contact with the outer flange 12 and extend upward. The installation method and the provision of the gap 14 are the same as those of the embodiment of FIGS. 1 and 2, but have the advantage that the portion protruding from the floor surface can be reduced.

However, in the case where the water drainage plug 1 is installed after the floor is stretched, there is usually no problem since a hole large enough to receive the operation unit structure 3 is often inserted from under the floor. However, when the floor is set up at the place where the water tap is installed, there is a case where only a hole just outside the outer diameter of the pipe 5 is opened, and in that case, there is an inconvenience that the hole has to be opened again.

[0016]

As described above, in the present invention, it is not necessary to disassemble the operation part structure 3 when installing the fixing bracket, and it is necessary to drain water with the antifreeze water tap on the upstream side in order to disassemble. Since there is no pipe, the construction is facilitated, and the inner fastening body is securely pressed onto the pipe by being pressed by the tapered inner diameter surface of the outer flange, so that the drain plug can be securely fixed to the floor.
