Adjustable rotation base

摘要

An adjustable rotation base includes a base housing and a transportation arrangement. The base housing has a bottom side, an upper side for coupling with the supporting post to support the outer umbrella in an upright manner, and a receiving cavity indently formed on the bottom side of the base housing, wherein the base housing includes a stationary unit provided at the bottom side for sitting on the ground surface in a stationary manner, and a plurality of transferring wheels rotatably supported at the bottom side of the base housing. The transportation arrangement is provided at the base housing to operate the base housing between an idle mode and a transportation mode in which the stationary unit is upwardly lifted to allow the transferring wheels being sitting on the ground surface, such that the base housing is adapted to be transported on the ground surface via the transferring wheels.

主权项

1. A base for an outdoor umbrella which comprises a supporting shaft supporting an awning frame thereat, wherein said base comprises:
a base housing arranged for coupling with said supporting shaft in an upright manner, wherein said base housing has a bottom side arranged for sitting on a ground surface in stationary manner, and a cavity for filling a stabilizing agent therein to substantially increase a weight of said base housing, wherein a support cavity is formed at said base housing for detachably receiving said supporting shaft of said outdoor umbrella so as to support said supporting shaft in an upright manner, wherein said base housing further comprises a plurality of housing bodies, wherein said cavity is defined at each of said housing bodies such that each of said housing bodies is adapted for filling said stabilizing agent therein, wherein each of said housing bodies further has a receiving cavity, wherein when said housing bodies are coupled with each other, said receiving cavities of said housing bodies form said support cavity for detachably receiving said supporting shaft; a plurality of transportation wheels supported within said base housing at corner portions thereof, wherein each of said transportation wheels is suspended above said bottom side of said base housing, wherein said transportation wheels are located at a bottom side of said base housing; and a transportation arrangement provided at said base housing to operatively actuate said transportation wheels, wherein said transportation arrangement is actuated to drop down said transportation wheel until said transportation wheels reach said ground surface, wherein after said transportation wheels stand on said ground surface, said transportation arrangement is kept actuating to uplift said base housing at a predetermined elevation with respect to the ground surface, wherein said base housing further comprises a plurality of elongated frame members connected to form a secure frame structure, and a plurality of connectors fastening said frame members to said housing bodies to secure said housing bodies on said base housing, wherein a thickness of each of said housing bodies where said connectors are fastened thereat is substantially increased.
