Patio Umbrella with Air Pump

摘要

An integrated pole unit is connected to a patio umbrella canopy and allows the canopy to be raised by a foot, hand or low pressure compressor pump and lowered by releasing air via an air pressure valve. The external umbrella pole is hollow with a slit at the top and contains an “internal pole mechanism” with a metal insert that is attached to the base of the canopy and moves up the slit with increased air pressure in the pole, which raises the umbrella canopy. There is an air pressure valve that, when closed, keeps the umbrella canopy in the full open position, and when open, releases the air, resulting in the umbrella canopy closing automatically in a slow and controlled manner.

主权项

1. A device for raising an umbrella canopy or other shading device with air pressure, the device comprising:
an external pole having a base at which the external pole is sealed; an internal pole received inside the external pole and sealed thereto above the base in a manner movable up and down within the external pole; an air connection system connected to the external pole; an air pump connected to the external pole by the air connection system and operable to pump air into the external pole to increase air pressure in the external pole and thereby raise the internal pole mechanism upwardly within the external pole; a longitudinal slit in the external pole; an insert sticking out from the internal pole mechanism through the slit in the external pole to carry a base of the umbrella canopy or other shading device for lifting of the umbrella canopy or other shading device under raising of the internal pole mechanism by operation of the air pump; and a lubrication opening on the internal pole at a position thereon that is accessible with the umbrella canopy or other shading device in a fully raised position.
