Abstract

The structure of the motor-operated umbrella is made to degrease rotation damage caused by a motor and to be light weight of the umbrella for using easily by a hand. A planetary gear mechanism consists of a sun gear, planetary gears and an internal gear that is arranged at border position between an upper middle shaft and a lower middle shaft, a lower end of a driving shaft inside the lower middle shaft is connecting to a motor rotating axle through a thrust bearing for transmitting a rotation of a motor, an upper end of the driving shaft is fixed to the sun gear, the outer cylinder is fitted with a cylindrical male thread is fixed to the internal gear, a male thread cover pipe is fitted with a supporting rib holder and an inner peripheral surface of the supporting rib holder is formed with a cylindrical female thread.

Description

technical field [0001] The present invention relates to an electric umbrella that is opened and closed by the operation of a motor. Background technique [0002] Conventionally, the "automatic opening and closing umbrella" of the following patent document 1 which can be opened and closed by the rotational operation of a motor is proposed. [0003] In this patent document 1, there is disclosed a structure in which when a threaded shaft inserted into a hollow-shaped support (equivalent to an umbrella pole (Japanese: middle stick)) is rotated by a motor provided on the handle, the screw threaded with the threaded shaft The joined threaded members are constrained to move up and down by a pin inserted into the groove opened in the pillar, and the sliding member (corresponding to the lower umbrella shaft) fixed to the pin moves the second frame (corresponding to the sub-rib) up and down. direction to open and close the umbrella.
