Self opening umbrella |
摘要 |
An improvement in self-opening umbrella frames having either a one-piece or telescopic stick and a main slide and an auxilary slide on the stick to operate the a frame-rib structure which is opened automatically by a coil spring compressed between these two slides; the frame-rib structure being closed by pulling down on a tubular grip sleeve journaled for rotation on the stick and extending through the two slides, the grip sleeve having an upper abutment or carrier engaged at the top of the auxilary slide; the grip sleeve being locatable about a 360 DEG circumference by an arresting catch on the umbrella handle at the lower end of the stick; torsional forces generated by the coiled spring during expansion and compression being isolated between the slides and not interferring with operation of the arresting catch while minimizing opening and closing effort of a user of the umbrella.
