Description

[Detailed Description of the Invention] The present invention relates to a floor box for storing an anti-freeze faucet installed under the floor.

In cold regions, to prevent water from freezing,
It is common practice to use an anti-freeze faucet to drain water from the pipes, but since the anti-freeze faucet protrudes above the floor, it is necessary to install it in a corner of the kitchen to avoid inconvenience in daily life. Or, it was often installed under the sink. As a result, it became troublesome to operate the anti-freeze faucet, and there were also problems such as when the shaft was pulled out due to a failure in the gasket, etc., it hit the sink and could not be pulled out.

Therefore, in this invention, the anti-freeze faucet is installed so that the handle is located below the floor without protruding above the floor, and a hole is made in the floor above the handle, and the lid is always covered and the anti-freeze faucet is installed. To operate it, remove the lid and put your hand under the floor to operate the handle. When you remove the lid, the bottom end is squeezed to prevent cold air from entering under the floor and the antifreeze water supply is closed. Attach a large-diameter bag that fits tightly to the pipe of the faucet to a flange fixed to the floor, and make the bag a long cylinder made of cloth to prevent the misalignment of the axis between the antifreeze faucet and the hole in the floor. In addition to making the lid part as simple as possible to reduce costs, we also designed a floor box that prevents the lid from opening and closing smoothly due to dirt, rust, etc. The purpose is to provide.

Next, the present invention will be explained based on an embodiment shown in the drawings.

In FIG. 1, reference numeral 1 designates a conventional antifreeze faucet, which is installed such that its lower part is buried in the ground, its upper part protrudes from the ground, and its operating part is located on the floor 2. 3 is a pipe and 4 is a handle. Drill a large diameter hole in the floor 2 above the anti-freeze faucet 1, and attach the flange 5 to the floor 2 with nails or wood screws 6.
Fixed to. The flange 5 has a large-diameter stepped portion 7 on the upper side thereof, and a groove portion 8 is formed on the lower outer peripheral portion thereof over the entire circumference. Reference numeral 9 denotes an upper lid, which is seated on the flange 5 so that an O-ring 10 attached to the outer periphery of the lid comes into contact with the stepped portion 7. A large diameter circular hole 11 is drilled in the center of the upper end, and a small hole 12 is further drilled in the center of the hole, and a thin rod portion 13 is inserted in the center as shown in FIG. 2 by passing through the small hole 12. , a T having a cylindrical stopper part 14 at the lower end, and screwed into the upper end a substantially rectangular knob part 15 which is tapered off at both ends of the circumference that fits into the circular hole 11 so that the lower side has a smaller diameter. A shaped handle 16 is seated in the circular hole 11.

At this time, the upper ends of the flange 5, the upper lid 9, and the handle 16 are made to be approximately at the same height. 1
Reference numeral 7 designates a long cylindrical bag made of cloth, whose upper and lower ends are folded back and attached to the groove 8 of the flange 5 by means of a wire 18 inserted into the folded portion so as not to easily come off. Inside the folded part at the bottom,
An elastic body 19 such as a spring or rubber is inserted so that the outer diameter of the pipe 3 is slightly smaller than the outer diameter in its natural state. When placing the bag 17 over the anti-freeze faucet 1, hold the handle 4 vertically and place the bag 17 over it.
Push open the lower end of the by hand against the elastic body 19,
It should be set so that the lower end is located on the pipe 3. The elastic body 19 can be set to have an appropriate strength in consideration of the tightening force applied to the pipe and the force of pushing it open by hand.

Since the present invention has the above configuration,
When operating the anti-freeze faucet 1, lift the knob part 15 with your fingers, the stopper part 14 will come into contact with the lower end of the top cover 9, and the top cover 9 will also rise, so remove the top cover 9 and place your hand inside the flange 5. Just put it in and operate the handle 4. At this time, since the bag 17 is in close contact with the groove 8 of the flange 9 and the pipe 3 by the wire 18 and the elastic body 19, the cold air under the floor does not blow up into the room. After you finish operating the handle, just put the top lid 9 back on. Since the O-ring 10 is attached to the top cover 9, there is no metallic sound when it is seated on the flange, and even if spilled water accumulates in the bag 17 or cold air under the floor gradually enters the room. It can prevent oozing. Since the bag 17 is made of cloth, it has more flexibility in dealing with misalignment between the antifreeze faucet 1 and the flange 5 than, for example, a rubber one, and does not require molding. The advantage is that the cost is gradually reduced because the process is completed.
Since the lower part of the knob part 15 is formed into a tapered shape with a small diameter, it is easy to lift.Furthermore, since the flange 9 does not use a hinge mechanism that rotates around a pin, after using it for a long time, The hinge part will not malfunction due to dirt or rust, and since the flange 5 and the top cover 9 are in O-ring contact, they will not stick together due to corrosion or the like after long-term use, unlike in the case of metal contact. There is no need to worry about not being able to remove the top cover.

As described above, in this invention, the antifreeze faucet does not protrude above the floor, so it does not cause any inconvenience in daily life, the installation location of the antifreeze faucet can be freely selected, and cold air does not blow up from under the floor. Since the bag is made of cloth, there is a large degree of freedom in dealing with misalignment of the axis between the antifreeze faucet and the flange.Furthermore, the lid opening/closing mechanism is simple and the flange and top lid are in O-ring contact, allowing for long-term use. It is possible to provide a low-cost floor box that eliminates the drawback that the lid becomes difficult to open while the box is being used.
