JPH11332624A - Umbrella with air vent - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent an umbrella from the risk of being blown away or broken by forming a slit for venting air at the upper part of the umbrella and providing a shielding means preventing both rain and wind from entering from outside through the slit at this slit so as to effectively vent wind blown into the inside of the umbrella. SOLUTION: A hole 2' is formed at the upper part of the umbrella and a small umbrella 1 is closely fitted so as to cover the hole 2'. Then, in a case when a strong wind blows in from a lower side, this small umbrella 1 opens upward to vent the wind and, when the wind stops, it returns to its original position by the force of a spring to prevent rain and wind entering from outside. Otherwise, it is possible to use a method of providing several holes at the top of the umbrella and covering these holes with a cloth from the top of the umbrella and to use a method of providing a long slit at the top of the umbrella and covering its edge with soft plastic, or the like, so as to bite each other from right and left. Thus, the umbrella is used without anxiety even on a day of strong wind since it is free from the risk of being blown away or broken by the strong wind.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described. (1) A hole is formed in the upper part of an umbrella, and a small umbrella (1) is adhered so as to cover the hole. In the strong wind from below,
When this small umbrella (1) opens upward to allow the wind to escape and the wind stops, the spring returns and prevents rain and wind from outside. (2) Make some holes at the top of the umbrella through which air can escape, and cover these holes with cloth from the top of the umbrella. If the cloth opens and allows the wind to escape and calms the wind, the cloths will overlap and prevent rain and wind from entering from outside. An appropriate weight can be attached to the lower end of the cloth so that the cloth adheres well to the umbrella. (3) A long cut is made at the top of the umbrella so that air can escape, and this edge is plugged from the left and right with soft plastic or rubber, etc., and the wind pressure from the inside of the umbrella is
The cut is opened, and from the outside, the edges of the cut are engaged with each other, so that the cut and the close contact prevent rain and wind from entering.

[0006]
