Abstract:
A protective structure for a button of an auto-umbrella comprising:a shell; a handle connecting with a lower end of a shaft and slidably received in said shell; a button to control an opening or closing of the umbrella positioned on the handle, medial to the shell; the shell having formed in a first side an upper aperture and a lower aperture; a screw hole formed in said shell and adapted to reversibly receive a rod; a lower groove formed in a first side of said handle for receiving a small spring and a ball; a U-shaped channel formed in a second side of said handle and comprising an upper horizontal space and a lower horizontal space joined by a vertical space, wherein the handle can be slidably positioned relative to said shell in either of two stable positions as the ball is biased by said small spring into either the upper aperture or the lower aperture of the shell, and an inner end of the rod is inserted into the the U-shaped channel so as to limit a movement of the handle relative to the shell without separation therefrom.
