[ What the invention claimed is:] [1.] A combination of travel bag and folding table, comprising:a travel bag having a top side, a bottom side, and a plurality of wheel holders respectively mounted on said bottom side, said wheel holders each holding a wheel;a table board having a fixed end pivoted
[ What the invention claimed is:] [1.] A combination of travel bag and folding table, comprising:a travel bag having a top side, a bottom side, and a plurality of wheel holders respectively mounted on said bottom side, said wheel holders each holding a wheel;a table board having a fixed end pivoted to the top side of said travel bag and a free end, the fixed end of said table board having a smoothly arched portion;hinge means coupled between the top side of said travel bag and the fixed end of said table board, said hinge means comprising a first leaf fixedly fastened to said travel bag, a second leaf integral with the smoothly arched portion of the fixed end of said table board, said first leaf having a plurality of longitudinally aligned barrels and a longitudinal locating groove adjacent to the barrels on said first leaf, said second leaf having a plurality of longitudinally aligned barrels, and a pivot pin mounted in the barrels at said first leaf and the barrels at said second leaf to secure said first leaf and said second leaf together, for permitting said table board to be turned about said pivot pin relative to said travel bag within a limited angle, said first leaf having a longitudinal locating groove, said second leaf having a flange at one side inserted into the longitudinal locating groove on said first leaf to limit the turning angle of said table board about said pivot pin;a retractable stand pivoted adjacent to the free end of said table board, said retractable stand comprising two coupling holder frames bilaterally pivoted to the fixed end of said table board at a bottom side by a respective pivot, said coupling holder frames each having a longitudinal sliding slot, two sleeves respectively pivoted to said coupling holder frames by a respective pivot, said sleeves each having a longitudinal sliding slot corresponding to the longitudinal sliding slots on said coupling holder frames, a control block connected between said sleeves at one end remote from said coupling holder frames, two inner tubes slidably inserted into said sleeves, a foot connected between said inner tubes at one end remote from said sleeves two side plates respectively coupled to said foot plate at two opposite sides and turned between a first position where said side plates are longitudinally aligned with said foot and a second position where said side plates are attached to a foot plate, two folding braces, said folding brace each having one end pivoted to one coupling holder frame and an opposite end pivoted to said table board, two push rods respectively coupled to said sleeves and moved along longitudinal sliding slots on said sleeves and said coupling holder frames, said push rods each having a hooked end extended out of the longitudinal sliding slots on said coupling holder frames and said sleeves and retained in contact with said folding braces, spring means respectively mounted in said coupling holder frames and imparting an outward pressure to said push rods respectively, said push rods being forced inwards to collapse said folding braces when said inner tubes are received in said sleeves, and two torsional springs respectively mounted on the pivots at said coupling holder frames, said torsional springs each having one end stopped at said table board and an opposite end connected to a lug at one coupling holder frame, said control block comprising two locating members, a spring connected between said locating members, said locating members each having a pin at an outer side respectively forced by the spring between said locating members into engagement with respective locating holes at said inner tubes to stop said inner tubes from axial movement in said sleeves, and a control knob coupled to said locating members, said locating members being pulled inwards to disengage the respective pins from the locating holes on said inner tubes when said control knob is depressed, for permitting said inner tubes to be moved in and out of said sleeves;first lock means for securing said table board, said retractable stand and said travel bag together when said table board is collapsed and attached to said travel bag, said first lock means comprising a knob mounted on said table board, a box at said table board remote from said knob, a link having a top end coupled to the knob of said first lock means and a bottom end inserted into said box, a movable hook coupled to the bottom end of said link inside said box, spring means mounted inside said box and imparting an upward pressure to said movable hook, and a fixed hook fixedly mounted on said travel bag at one side, said fixed hook being inserted through a hole on said box into engagement with said movable hook to secure said table board in place when said table board is closed on said travel bag, said movable hook being disengaged from said fixed hook when the knob of said first lock means is depressed, said link having a hook, the hook of said link being forced into engagement with the foot of said retractable stand when said retractable stand is collapsed and attached to said table board; andsecond lock means for stopping the wheels of said travel bag from moving.
