Abstract

<P>PROBLEM TO BE SOLVED: To solve problems of a conventional umbrella which is blown away, warped or broken in the event of a strong wind, on account of wind pressure produced from a current of air built up inside the umbrella, and to eliminate such problems by reducing the wind pressure. <P>SOLUTION: A slit is formed vertically between the ribs of an umbrella, making a wind to blow through. The edge of the slits is hemmed, making them closed as before after the wind blows through. The hem of the slits is extended to form rain guiding lines, so that rain water entering inside is guided along the lines and prevented from dripping in the middle inside the umbrella. The rain guide lines outside the umbrella can prevent rain water from infiltrating through the slits and guide the rain water to the outside of the umbrella. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to an umbrella.

  Traditionally, there are umbrellas that protect the body from rain and sunlight.

Conventional umbrellas can prevent rain and sunlight when there is no wind or light winds, but winds accumulate inside the umbrella when there are strong winds, and the wind pressure causes the umbrella to be blown off, warped, broken, Does not play the role of an umbrella.
In addition, an umbrella here means all things which protect a body from rain, sunlight, etc., such as a parasol, a rain umbrella, a parasol, and a tent.

  Therefore, the present invention aims to provide a structure that prevents the umbrella from being broken, blown off, or warped when strong winds pass through the wind by making cuts, and at the same time serves as an umbrella and enhances safety. And

  In addition, the purpose is to prevent rainwater from entering and dripping inside the umbrella due to its structure, and to improve the role and comfort of the umbrella.

  The present invention is intended to solve the problems of such a conventional structure, and aims to effectively reduce the wind pressure received by the umbrella and to realize the safety of the umbrella in a strong wind. To do. At the same time, the structure is intended to prevent rainwater from entering the umbrella.

In order to achieve the above-mentioned object, the invention according to claim 1 is characterized in that wind is easily accumulated at the upper part of the umbrella and is easily subjected to wind pressure, and a straight cut is made between the bones of the umbrella. To create a structure that allows the wind to blow through. Its structure allows the umbrella to function as an umbrella without being broken, blown away, or warped by wind pressure, and at the same time increases safety. In addition, in the case of strong winds, the wind pressure can be reduced from the outside, so the wind pressure can be reduced and safety is improved. (Fig. 1 and 2)
The term “edge” as used herein refers to all edges including edge reinforcement.

  According to the second aspect of the present invention, the vertical cut is normally kept closed in order to prevent rainwater and sunlight from entering the inside after the cut is opened and the wind is removed. (Figure 2)

  Since the edge of the notch is edged, it is easy to adhere, and the edging is extended to form a rainwater induction line. (Figs. 3 and 4) When rainwater enters the inside, it is guided out of the umbrella along the rainwater guide line attached to the inside. (FIG. 5) When the umbrella is closed, the outside rainwater flows along the rainwater induction line provided outside the notch, and therefore (FIG. 6) does not enter and accumulate inside the umbrella.

  According to the first aspect of the present invention, it is possible to prevent the umbrella from being blown off, warped, or broken by smoothly flowing the wind accumulated on the inside to the outside. At the same time, safety can be increased.

  According to the second aspect of the present invention, it is possible to eliminate the possibility that rainwater may leak due to its structure.

  External view when the umbrella which shows 1st Embodiment of this invention is opened   Similarly, a cut view showing when the wind blows and does not blow showing the embodiment   Similarly, the rainwater induction line diagram of the outside and inside of the umbrella showing the second embodiment   Similarly, enlarged and cross-sectional view of an umbrella rainwater induction line showing an embodiment   Similarly, the role figure of the rainwater induction line when the umbrella showing the embodiment is opened   Similarly, the role figure of the rainwater guidance line when the umbrella showing the embodiment is closed

  Hereinafter, a first embodiment embodying the present description will be described with reference to the drawings.

  As shown in Figure 1, at the location where the wind tends to accumulate at the top of the umbrella and is subject to wind pressure, the structure is such that the wind blows out by making a straight cut between the bones of the umbrella and making a straight cut. To do. Its structure allows the umbrella to function as an umbrella without being broken, blown away, or warped by wind pressure, and at the same time increases safety. In addition, in the case of strong winds, the wind is removed from the outside, reducing the wind pressure and increasing safety.

  As shown in FIG. 2, when there is no wind or light wind, the vertical cuts are normally kept closed to prevent rainwater sun from entering inside. The edge of the notch is edging, so both sides of the edge are in close contact, and rainwater and sunlight do not enter inside. (FIGS. 3, 4, and 5) When rainwater enters the inside, it is guided out of the umbrella along the rainwater guide line attached to the inside, so that the rainwater does not drip inside the umbrella.

  As shown in FIG. 6, when the umbrella is closed, the outside rainwater flows along the rainwater induction line provided outside the notch, and therefore does not enter and accumulate inside the umbrella.

  Parasol, parasol, parasol, tent, etc.

(A) Outside umbrella cut and rainwater induction line (B) Inside umbrella cut and rainwater induction line

Claims (2)

  A notch is made vertically between the umbrella bones, and the edges of the notches are rimmed and closely closed from both sides. An umbrella characterized by an open notch when strong winds pass through the wind, and when the wind is not blowing, the notch is closed and rainwater and sunlight do not enter inside.   The edge of the notch is extended to form a rainwater induction line. When the umbrella is open, rainwater outside the umbrella and rainwater that has entered inside are guided outside the umbrella, and when the umbrella is closed The umbrella according to claim 1, wherein rainwater flows along the rainwater guide line of the water and the rainwater does not enter inside from the cut and is guided outside the umbrella.
