Description

Rotating retractable ventilation aparatus}

The present invention relates to a rotational opening/closing ventilation device that provides air permeability to fabrics used in clothing, tents, etc. to prevent moisture or condensation from occurring in the inner space of the fabric.

In general, clothing including everyday wear, work clothes, mountaineering clothes, sportswear, raincoats, etc. is mostly made of synthetic fiber material, which is a functional material in consideration of functionality to improve waterproofness, elasticity, or wearing comfort. are giving

When the body temperature rises due to the material of the clothing as described above, condensation occurs in which moisture is formed on the inner surface of the clothing due to the temperature difference between the body temperature and the air temperature. do.

As described above, when the inside of the clothing increases in moisture, the inner surface of the clothing not only sticks directly to the skin, but also increases the body temperature and causes a lot of sweat, which increases the consumption of physical strength and causes skin diseases due to waste products contained in sweat There is a problem with

In particular, in the rainy season or summer season, the temperature and humidity are relatively high, and as the body temperature further rises and causes more sweat, the above problems inevitably appear more severely.

In order to solve the disadvantages caused by the lack of air permeability of these clothes, the air that exists inside the clothes is naturally discharged to the outside, and the air permeability of the clothes must be strengthened so that the outside air is naturally introduced into the clothes.

To this end, functional clothes have been devised in which a ventilation means is additionally installed on the outer shell of the clothing to allow outside air to flow into the clothing while allowing the inner air of the clothing to be discharged to the outside.

That is, functional clothing in which a ventilation hole of a predetermined diameter is formed in the outer garment and an eyelet is installed in the ventilation hole, or a ventilation hole is formed in a horizontal or vertical direction in the outer garment and covered with a separate fabric so as to communicate with the outside, has been devised.

However, since the conventional functional clothing described above simply has ventilation holes formed in the outer shell, there is a problem in that ventilation is not properly performed because the outer shell is wrinkled or folded by a user's movement, so that the ventilation holes are easily closed. In addition, since rainwater may flow into the ventilation hole in a state in which the ventilation hole is opened by a user's motion change, there is also a problem that the inside of the clothing is easily wet with rainwater.

On the other hand, as the tent is also made of fabric like clothing, a ventilation hole is provided for the purpose of preventing condensation or ventilation. However, the vent hole is covered with a mesh net for insect repellency, and a shielding member is provided on the upper side of the vent hole to prevent rain from entering through the mesh net.

However, when a strong wind blows in the place where the tent is installed and a lot of rain falls, the covering member flutters and rain easily flows in through the vent or the vent is completely blocked, resulting in poor ventilation and severe dew condensation inside the tent. There is a problem.

Therefore, it is installed on fabrics that make up clothes and tents to provide smooth ventilation, and despite the opening of the ventilation holes, rainwater does not flow into the inner space formed by the fabric through the ventilation holes, so it can block rainwater reliably. It is necessary to develop a retractable ventilation device.
