Description
Technical Field
The utility model relates to a sunshade, rain-proof technical field specifically relate to a solar protection devices.
Background
The game of golf is an item of sports that uses different golf clubs (club) to drive a golf ball into a hole (hole). The golf game is a game with special charm, which makes people exercise body, cultivate feelings and exercises, repair body and maintenance and exchange skills in beautiful natural environment, and is praised as fashionable and elegant game.
Golf courses are generally installed outdoors in open air and are difficult to avoid in rainy days or in the weather with strong ultraviolet intensity. The physical health and physical and mental pleasure of athletes are affected by rain and sunshine exposure. As the pain point of golf, the current solutions are mainly the following, one of which is that the athlete opens the umbrella by himself. And the other is to arrange an umbrella canopy at the batting place/rest point. Thirdly, hiring a ball child to hold an umbrella.
The first solution has the drawback that, firstly, both the playing of the umbrella and the playing of the ball cannot be considered simultaneously, i.e. the playing of the umbrella must be stopped and the playing of the ball must be stopped. Secondly, although a player can play an umbrella by himself or herself in the process of moving from the a hitting place to the B hitting place, the golf player often carries a golf bag, and it is very inconvenient to play the umbrella by himself or herself.
The second solution has the drawbacks that: movement and placement of the canopy is difficult. The location of the golf ball is often changed. It is difficult for players to shade from the sun or rain using a bulky canopy while moving from the a shot point to the B shot point. On the other hand, after the player finishes hitting the ball at the ball hitting place A or the rest at the rest place X, the player needs to move the canopy to the ball hitting place B or the rest place Y, and the processes of moving the canopy and retracting and unfolding the canopy are very complicated.
The third solution has the drawback that firstly, additional costs are added; secondly, it is unacceptable for athletes who want to enjoy private spaces; moreover, when a player hits a ball, obstacles and people in a certain range around the player need to be cleaned, so that the player does not influence the swing of the player, and the ball hitting experience is reduced. If the peripheral obstacles and people are not cleared, the athlete can hit the peripheral obstacles or injure the peripheral people by mistake when swinging. Thus, the caddie does not have the condition of putting an umbrella at all during the period of time the player is ready to hit the ball and hit the ball.
