The present invention relates to an angle adjusting device of a parasol, and more particularly, in a parasol used to block direct sunlight of the sun or to avoid rain at a beach or fishing ground, according to a change in the position of the sun or the direction of the wind over time. It relates to a parasol angle adjusting device that can change the angle or direction of the sun visor according to the angle or direction that can block the direct sunlight or rain of the sun according to the direction of the falling rain.

Parasols are used to block direct sunlight from the sun or to avoid rain at beaches and fishing spots. Parasol having this function should be able to change the direction of the sunshade according to the change in the position of the sun or the direction of the falling rain so that the user can effectively avoid direct sunlight or rain.

For this purpose, a parasol angle adjusting device of various structures has been disclosed. An example is described in Korean Utility Model Publication No. 20-0286604. The design of No. 20-0286604 is provided with a ball formed with a hole so as to engage the props of the parasol, and an upper holder and a lower holder with flanges formed at the edges of the ball. It discloses a parasol angle adjusting device for adjusting the angle of the parasol by wrapping the band and tightening or loosening the band with a bolt.

The design of No. 20-0286604 has the advantage that the angle adjustment is easy in terms of adjusting the angle of the parasol by connecting the ball wrapped by the upper and lower holders to the prop of the parasol. It is required.

First, according to the design of No. 20-028660, in the case of a large parasol, the angle adjusting operation is very difficult. If one user adjusts the inclination angle of the parasol, the band should be unscrewed with one hand, and the other hand should hold the parasol's prop and adjust the inclination, especially for large parasols. This is because it is not easy to keep the inclination of the prop in proper position while loosening and tightening the weight and at the same time overcoming the weight of the parasol with the other hand.

Next, the design of No. 20-0286604 is to open all the upper portion of the upper holder and set the angle of the parasol to one point of the open point, and then tighten the flange around the upper and lower holes around the center of the ball using a band. In this structure, there is a problem in that the parasol having a large sunscreen cannot maintain the angle as necessary. For large parasols, the sunscreen, the barrel, the sliding doors, and the weight of the flesh are so heavy that it is possible to completely cross in the inclined direction within a short time by simply tightening the band to the center of the ball. Particularly, when the inclination angle of the parasol is large, the load in the vertical direction (vertical component of the load) becomes very large, and according to the design of No. 20-028660, the parasol can hardly be maintained in an inclined state.

The parasol angle adjusting device according to the present invention devised to solve the problems of the prior art described above is to provide a parasol angle adjusting device of the structure that can be easily adjusted by one user even in the case of a large parasol. There is this.

Another object of the present invention is to provide a parasol angle adjusting device that can be firmly stopped at a constant inclination even in the case of large parasols, and that the parasol can be reliably maintained even when the inclination angle is large.
