Wheeled suitcase having dual extractable handle assemblies

Abstract

A wheeled suitcase has dual extractable handle assemblies. The first extractable handle assembly is positioned immediately adjacent to the rear side of wheeled suitcase for pulling and wheeling the wheeled suitcase in inclined position. The second extractable handle assembly is positioned immediately adjacent to the bottom side of wheeled suitcase for loading an add-on traveling case.

1 . A wheeled suitcase comprising of:
 a front side for accessing interior of said wheeled suitcase, a rear side opposite and parallel to said front side, a top and bottom sides opposite and parallel to each other, and a left and right sides opposite and parallel to each other; and   a pair of wheel assemblies anchored to said bottom side immediately adjacent to said rear side of said wheeled suitcase; and   a first extractable handle assembly fixedly anchored immediately adjacent to said rear side of said wheeled suitcase, capable of being retracted to a fully retracted compact position, and extracted to a fully extracted position for pulling and wheeling said wheeled suitcase in an inclined traveling position; and   a second extractable handle assembly fixedly anchored immediately adjacent to said bottom side of said wheeled suitcase, capable of being retracted to a fully retracted compact position, and extracted to a fully extracted position to form a landing area for loading an add-on case; and   a pair of foot stands fixedly connected to said second extractable handle assembly, capable of supporting said wheeled suitcase in a self standing upright position when said second extractable handle assembly is in said fully retracted compact position, and when said second extractable handle assembly is in said fully extracted position for loading said add-on case; and   a first and second anchoring means for fixedly anchoring said first and second extractable handle assemblies respectively, capable of being interconnected to each other to sustain a bending moment due to the combined weight of said wheeled suitcase and said add-on case when said wheeled suitcase being tilted from said self standing upright position to said inclined traveling position; and   a first and second locking and releasing means for operating said first and second extractable handle assemblies respectively between said fully retracted compact position and said fully extracted position.   
     
     
         2 . The wheeled suitcase according to  claim 1 , in which:
 said first anchoring means comprises of a L-angle plate having a vertical and horizontal sectional plates, and two sockets integrally connected to said vertical sectional plate of said L-angle plate for receiving and fixedly connecting to a pair of guide tracks of said first extractable handle assembly; and   said second anchoring means comprises of a L-angle plate having a vertical and horizontal sectional plates, and two sockets integrally connected to said horizontal sectional plate of said L-angle plate for receiving and fixedly connecting to a pair of guide tracks of said second extractable handle assembly; and   said first and second anchoring means are interconnected by overlapping and fixedly connecting said vertical and horizontal sectional plates of said L-angle plate of said second anchoring means to said vertical and horizontal sectional plates of said L-angle plate of said first anchoring means respectively.   
     
     
         3 . The wheeled suitcase according to  claim 1 , in which:
 said first anchoring means comprises of a L-angle plate having a vertical and horizontal sectional plates, and two sockets integrally connected to said vertical sectional plate of said L-angle plate for receiving and fixedly connecting to a pair of guide tracks of said first extractable handle assembly; and   said second anchoring means comprises of a horizontal plate, and two sockets integrally connected to said horizontal plate for receiving and fixedly connecting to a pair of guide tracks of said second extractable handle assembly; and   said first and second anchoring means are interconnected by overlapping and fixedly connecting said horizontal plate of said second anchoring means to said horizontal sectional plate of said L-angle plate of said first anchoring means.   
     
     
         4 . The wheeled suitcase according to  claim 1 , in which:
 said first anchoring means comprises of a L-angle plate having a vertical and horizontal sectional plates, and two sockets integrally connected to said vertical sectional plate of said L-angle plate for receiving and fixedly connecting to a pair of guide tracks of said first extractable handle assembly; and   said second anchoring means comprises of a horizontal plate, and a pair of guide tracks of said second extractable handle assembly fixedly connected to said horizontal plate; and   said first and second anchoring means are interconnected by overlapping and fixedly connecting said horizontal plate of said second anchoring means to said horizontal sectional plate of said L-angle plate of said first anchoring means.   
     
     
         5 . The wheeled suitcase according to  claim 1 , in which:
 said second extractable handle assembly comprises of a pair of guide tracks, a pair of sliding tracks capable of sliding freely within said guide tracks, and a cross bar handle fixedly connected to the front ends of said sliding tracks; and   said foot stands are fixedly connected to said second extractable handle assembly at the joints between said sliding tracks and said cross bar handle.   
     
     
         6 . The second extractable handle assembly according to  claim 5 , in which:
 said guide tracks are made of u-shape channel bars, and said sliding tracks are made of box-shape channel bars integrally connected to a center plate, so that said sliding tracks and said center plate form an integral piece slidable along said guide tracks.   
     
     
         7 . The wheeled suitcase according to  claim 1 , in which:
 said second extractable handle assembly comprises of a pair of guide tracks, a first pair of sliding tracks capable of sliding freely within said guide tracks, a second pair of sliding tracks capable of sliding freely within said first pair of sliding tracks, and a cross bar handle fixedly connected to the front ends of said second pair of sliding tracks; and   said foot stands are fixedly connected to said second extractable handle assembly at the joints between said second pair of sliding tracks and said cross bar handle.   
     
     
         8 . The second extractable handle assembly according to  claim 7 , in which:
 said guide tracks are made of u-shape channel bars; and   said first and second pairs of sliding tracks are made of box-shape channel bars; and   said first pair of sliding tracks are integrally connected to a center plate, so that said first pair of sliding tracks and said center plate form an integral piece slidable along said guide tracks.
