Patent ID: 7490797

Claim:
A portable supporting apparatus for a portable multimedia device, comprising: a support housing which comprises a multimedia connector for detachably connecting with said portable multimedia device; and a mounting arrangement which is provided underneath said support housing, and comprises a plurality of supporting legs, each having a predetermined shape, pivotally and downwardly extended from said support housing, wherein said supporting legs are adapted to move between an idle position and a mounting position, wherein in said idle position, each of said supporting legs is pivotally and downwardly extended from said support housing for being conveniently transported and stored, wherein in said mounting position, each of said supporting legs is pivotally moved to form a predetermined angle of inclination with respect to said support housing so as to bias against an external object for frictionally retaining a position of said support housing with respect to said external object, such that said portable multimedia device is capable of being securely supported by said external object through said portable supporting apparatus, wherein each of said supporting legs has a curved cross-sectional shape extending from said support housing to a lower end portion of said respective supporting leg for optimally clamping onto said external object in a frictional manner, wherein said mounting arrangement further comprises a locking device provided at said support housing to operatively couple with said supporting legs in such a manner that said locking device is adapted to optimally lock up said supporting legs in said mounting position so as to ensure that said supporting legs are locked and retained at a particular position for stably and frictionally mounting onto said external object, wherein said locking device comprises a lock member comprising a locker cap, having a plurality of locker slots spacedly formed on a sidewall of said locker cap, movably mounted and inclinedly extended underneath said support housing, wherein said supporting legs, which are pivotally connected with said support housing, are arranged to pass through said locker slots respectively in such a manner that an upward pivotal movement of each of said supporting legs is restricted by a top edge of said corresponding locker slot.
