Patent ID: 7422343

Claim:
An outdoor umbrella, comprising: an awning; a main frame comprising a tubular first post having a first connector end, a tubular second post having a second connector end detachably coupling with said first connector end of said first post in an end-to-end manner to form an elongated supporting post, and an awning supporting frame provided on top of said supporting post to support said awning to define a shading area thereunder; an illumination system provided on said main frame for illuminating said shading area of said awning; and an illumination wiring arrangement, which comprises: a first wiring unit comprising a connector plug provided within said first connector end of said first post to electrically connect to said illumination system; and a second wiring unit comprising a power socket which is electrically extended from a power source and is extended within said second post at said second connector end thereof in a suspended manner to electrically connect to said connector plug in a detachably connecting manner, wherein when said first post is coupled with said second post, said power socket is free to move within said second post to keep intact an electrical connection between said power socket and said connector plug so as to ensure said illumination system electrically connecting with said power source through said illumination wiring arrangement when vibration occurs at said main frame, wherein said illumination wiring arrangement further comprises a supporting seat securely mounted at said second connector end of said second post and a suspension element substantially supported at said supporting seat for applying an urging force against said power socket towards said connector plug for not only absorbing said vibration induced at said power socket but also ensuring said connector plug being electrically connected with said power socket, wherein said suspension element comprises a compression spring, which is coaxially supported within said second post, having two ends substantially biasing against said supporting seat and said power socket such that said compression spring not only acts as a vibration absorber for substantially absorbing said vibration induced at said power socket when said vibration occurs at said main frame but also ensures said connector plug being electrically connected with said power socket when said compression spring pushes said power socket towards said connector plug.
