Patent ID: 6865985

Claim:
A foldable panel supporter, comprising: a supporting leg frame which comprises a lower supporting frame and an upper connecting frame, wherein said upper connecting frame comprises a pair of resilient connecting arms adapted for being inwardly pressed to reduce a distance between said two connecting arms; a supporter joint which has a folding channel provided thereon, wherein said folding channel has two holding portions at two ends thereof and a retaining portion extending between said two holding portions, wherein said retaining portion has a width narrower than said two holding portions, wherein each of said holding portions is shaped and sized to receive said connecting arms therein, wherein by slightly and inwardly pressing said connecting arms to an extent that a distance between said connecting arms is equal to said width of said retaining portion, said upper supporting frame is capable of sliding from one of said holding portions to another said holding portion; and means for retaining said upper connecting frame in said folding channel of said supporting joint in a pivotally foldable manner so as to pivotally connect said supporting leg frame with said supporting joint together, wherein said retaining portion which is narrower than said holding portions of said folding channel prevents said upper connecting frame of said supporting leg frame from sliding back from one of said holding portion to another said holding portion along said folding channel unless a compression force is applied to move said two connecting arms together, wherein said folding channel is defined between two arc-shaped side walls of said supporter joint, wherein middle portions of said two side walls are closest with each other so as to define a narrowest mid-portion of said retaining portion which two ends gradually increases a width thereof to said two holding portions to form said folding channel, wherein when said two connecting arms is positioned at one of said holding portions, said supporting leg frame is retained in position because said two arc-shaped side walls substantially prevent said two connecting arms from moving towards said retaining portion unless said upper connecting frame is pressed to move from one of said holding portions to another said holding portion along said folding channel, wherein said two connecting arms are being pressed towards each other by said two arc-shaped side walls while passing through said retaining portion.
