摘要： The presently disclosed umbrella device accomplishes both automatic opening, as accomplished by the previous art (but by a means different from that of the prior art) and in addition discloses a means by which the automatic closing of the umbrella can be accomplished (by a means not disclosed in the prior art). Novel mechanical means are used to open and close the umbrella without the need to move the hand from its normal position on the handle (13 or 58), the normal carrying position. A preferred embodiment of the invention uses compressed gas in an ampule (23) to extend a spring (7) provided for the opening of the umbrella (1) while extending the telescoped handle cylinders (9 and 5) which closes the umbrella. The preferred embodiment also features a sleeve (12) which can simultaneously exhaust gas to atmosphere through the port (18) while releasing the mechanical latch (34) to allow a spring (7) to telescope the handle cylinders (5 and 9) and deploy the umbrella canopy (11).

摘要： The invention relates to umbrellas which automatically open and close. This automatic opening and closing of the umbrella (1) is accomplished by means of the rotation of a threaded rod (63) located inside the hollow shaft (5) of the umbrella (1) in which a pin (67A) directly engaging the threaded rod (63) through a slot (31) in the shaft (5) is attached to a collar (62) which slides up and down the outside of the umbrella shaft (5). The collar (62) is attached to the struts (2) connected to the ribs (7) of the umbrella to which is attached the water repellent cloth (8). Rotation of the threaded rod (63) as by a small electric motor (27) moves the pin (67A) engaged with the threaded rod (63) which moves the collar (62) up and down the outside of the umbrella shaft (5) thereby opening and closing the umbrella. The manual disengagement of the pin (67A) from the threaded rod (63) allows the collar (62) to be manually moved up and down the shaft (5) of the umbrella.
