Abstract:
1. A multifunctional furniture, comprising: a stationary seat frame; a supporting frame rearwardly extended from said stationary seat frame; a back frame pivotally connected to said stationary seat frame to move between a sitting mode and a bedding mode; and a leg frame arrangement which comprises a plurality of supporting legs spacedly mounted underneath said supporting frame and a foldable leg frame foldably provided on a rear side of said back frame, wherein when said back frame is in said sitting mode, said back frame is pivotally extended from said seat frame at a predetermined angle of inclination while said foldable leg frame is folded to rest on said rear side of said back frame, wherein when said back frame is in said bedding mode, said back frame is pivotally moved to align with said seat frame to form a sleeping area and is supported by said supporting frame, wherein at said bedding mode, said foldable leg frame is unfolded to extend from said rear side of said back frame for providing an additional leg support to said back frame, wherein said foldable leg frame comprises a leg member having an elongated shape for standing on a ground surface, a base member mounted at said rear side of said back frame, and a folding mechanism pivotally connecting said back frame and a first end of said leg member to allow a second end of said leg member folding to extend from said rear side of said back frame for standing on the ground surface, wherein said base member comprises a base wall mounted onto said back frame and two sidewalls extended from said base wall to form a U-shaped receiving cavity between said base wall and said sidewalls, wherein said folding mechanism comprises a folding guider coupled at said first end of said leg member and pivotally mounted between said two sidewalls of said base member, so that when said folding guider is driven to move pivotally with respect to said base member, said leg member is also driven to move accordingly to extend from said rear side of said back frame, wherein said folding guider has a mounting base and two side panels extended from said mounting base to define a guiding cavity between said mounting base and said two side panels, wherein said first end of said leg member is securely mounted on said mounting base, wherein said folding mechanism further has two curved slots formed at said sidewalls of said base member respectively and comprises a pivot member which passes through said curved slots and extends across said two side panels, such that when said leg member is pivotally folded, said pivot member is guided to slide at said curved slots so as to guide a folding movement of said leg member, wherein each of said curved slots has an enlarged section and a contracted section, wherein said folding mechanism further comprises a locking device for locking said leg member when said leg member is folded to extend from said rear side of said back frame, wherein said locking device comprises a locking member provided at said pivot member and has a diameter matching with said enlarged section of each of said curved slots, wherein said locking member has a contracted pivot section having a diameter matching with said contracted section of each of said curved slots, wherein when said locking member is located at said enlarged section of said curved slot, said leg member is locked at a position that said leg member is folded to extend from said rear side of said back frame, wherein when said pivot member is pressed inwardly to move said contracted pivot section aligning with said curved slot, said contracted pivot section is guided to slide to said contracted section of said curved slot so as to allow said folding movement of said leg member.
