JPS5930137Y2 - Overflow conduit cover - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to an improvement of a cover for a conduit for treating overflow water.

Conventionally, overflow conduits for pools and other facilities are covered with small iron plates with holes drilled in them, but when you run on them, the iron plates lift up and move, causing people to trip over them. This is dangerous, and when cleaning the waterway, the iron plates have to be removed one by one and laid out again, which is quite time-consuming.

There are also those that sandwich separate spacers between multiple plates and connect them in a series with a string, and those that use the spacers themselves as a connecting tool, but they require time and effort to assemble, and It is easy to break due to excessive force, and there are still few products that are satisfactory.

The present invention eliminates the above drawbacks and further improves them.
Connect the base pieces lined up on the water conduit in a series with string-like connectors,
A protruding piece is integrally formed on the side surface of the base piece, thereby forming a gap between adjacent base pieces through which overflow water can pass.

In the following embodiments, the base piece 1 is made of fiber-reinforced polyester resin material, metals such as iron and aluminum, plastics, composite materials thereof, and other water-resistant materials.
Using a corrosion-resistant material, it is molded into a hollow or solid substantially rod shape by injection, press molding, or other appropriate method, and the protruding piece 2 is integrally formed from at least one side of the rod.

These base pieces are lined up and connected by a string-like connector 3.

For this connector, ropes made of synthetic fibers, synthetic resins, etc., stainless steel wires, and other water-resistant and corrosion-resistant materials are suitably used. The protruding pieces 2 and the corresponding base pieces are passed through holes 4 provided in the side surfaces of the protruding pieces 2 and the corresponding base pieces to form a gap.

When the protruding pieces are abutted against each other between adjacent base pieces, the gap distance can be changed.

When these base pieces 1 are laid across the headrace 6 of the pool 5, the top surface of the headrace is covered and overflow water enters the headrace through the gaps between the base pieces and is treated. Ru.

The illustrated one has a small protrusion 7 on the upper surface of the base piece.

The one shown in Fig. 4 has a protruding piece 2 provided at the center of the side surface of the base piece, and can be suitably used for a bent part of a water conduit or the same curved part. By inserting another cord 8 and fitting a clip 9 to it from the back side of the base piece if necessary, it is possible to further prevent the base pieces from shifting relative to each other.

In addition, if the head of the protruding piece 2 is made into an arc shape as shown in the figure, and the side surface of the adjacent base piece that comes into contact with the acid base pieces when they are lined up is made concave in correspondence with the protruding piece, both are in a fitted state, and the side base pieces are further stabilized.

Since the present invention has the above-mentioned structure, even if the base piece runs on top of this cover and tries to lift up, it will be immediately pulled back to its original state and removed because it is connected with the connecting device. This does not happen, and since it can be rolled up one by one by holding the end and pulling it up, it can be easily removed from the surface of the water channel, and cleaning is also easy, and if it is rewound again, it can be used to cover the water channel as it is. .

The protruding pieces that form the gaps between the base pieces are formed integrally with the base pieces, so even if a strong force is exerted by someone riding on the cover, the base pieces will not break apart. Although the gaps between the pieces do not disappear or become wider, you can walk on them with peace of mind, and drainage continues to occur smoothly.

Note that the present invention can be widely applied to bathrooms, channels for chemical liquids, and other channels.
