JPS5849325Y2 - Accident prevention lid at pool suction port - Google Patents

Description

[Detailed explanation of the invention] This invention is a button that is attached to the swimming pool and attached to the suction port of the purification device.
This relates to a lid for preventing drowning accidents.

If you press the button on the swimming pool, the suction pump of the purifier will be at maximum 0.
-5kVcr;? Impurities in the liquid are removed by suctioning the pool water with negative pressure before and after and passing it through a filter. For example, if the pores of 100 d are covered and blocked all over, it will be suctioned with a negative pressure of 50 kg. Especially young children are unable to overcome this and escape underwater, leading to accidents.

The present invention was developed by focusing on the above-mentioned points, and its purpose is to prevent the suction restraint accident of the human body by making the structure simple and installing it to cover the suction port. To provide an accident prevention lid.

An example of Tanoshiki's invention will be explained with drawings.
Reference numeral 1 indicates the bottom surface of the pool, and a suction port 2 of the purification device is provided.

A grating lid 3 is usually provided above the suction port 2 to prevent dirt from being suctioned into the pump and becoming impossible to purify.

During cleaning, the water in the tank is drained from the suction port 2.
There is a possibility of forgetting to fit the lattice cover 3.

Reference numeral 4 denotes a hemispherical frame-shaped synthetic resin prevention lid provided to cover the suction port 2, and arcuate ribs 4 extending radially from the top 4'.
In contrast to a, concentric annular ribs 4b are integrally combined to form a substantially lattice shape, and the radial arcuate ribs 4a and annular ribs 4b are formed thickly toward the center. The plurality of thick annular ribs 4b are arranged in a radial direction when viewed from the hemispherical center.

The annular rib closest to the bottom surface 1 is a horizontal plate portion 4c,
It is fixed to the bottom surface 1 using a double-sided suction tool 5 and an adhesive 6.

The liquid passage gaps 4' formed by the ribs 4a and 4b are provided evenly over the entire surface and have a size that does not allow the infant's wrist to fit into each one, and the overall size is 30 Crr1 in diameter.
However, no matter how big or small it is, 80% or more of the body cannot be covered closely.

Therefore, even if the suction of the pump of the purification device is strong, the liquid is passed from other parts of the body that are not covered, so the suction force on the body will not become as large as mentioned above, and accidents can be prevented. Ru.

As described above, in the present invention, the overall shape of the prevention lid is formed into a substantially hemispherical frame shape that is not completely covered by the human body. Therefore, even infants can escape by themselves, and drowning accidents caused by conventional physical restraints can be prevented.

In addition, in the present invention, the radial rib and the annular rib are integrally combined, and the rib is formed with a thick width, so it has excellent strength. Since the tank is disposed in the tank, suction is performed evenly over the entire area inside the tank, and impurities are evenly sucked out, and there is no generation of swirling currents that rarely occur, and there is no problem with drainage.

The lattice lid can be opened and closed using a rod-shaped opening/closing tool through the gap in the prevention lid, so it does not interfere with cleaning, and regardless of whether it is an existing or new installation, the installation of an inexpensive prevention lid allows swimming with peace of mind. This is something that can be done and is extremely meaningful from a management perspective.

Claims (1)

[Scope of utility model registration request] It is formed into a substantially hemispherical frame shape of a size that is not completely covered by the human body, and is formed into a lattice shape with a plurality of arcuate ribs 4a and concentric annular ribs 4b provided in the radial direction from the top of the frame, and the ribs are formed into a hemispherical frame. A plurality of annular ribs are formed in a relatively thick width toward the inside of the hemispherical shape, and a plurality of annular ribs are arranged in a radial direction from the center of the hemisphere, and the annular rib 4c is fixed to the suction port via the annular rib 4c closest to the bottom surface. An accident prevention lid that can be clicked on the pool suction opening.
