Collapsible rolling luggage

Abstract

The invention relates to a collapsible luggage bag that improves maneuverability of the bag when a user is towing the bag and collapses to a reduced size to improve portability. In particular, the invention relates to a handle that is slideably interconnected to one or more stays such that the upper ends of the stays change position along the length of the handle as the handle retracts into the luggage. Further, the handle disconnects from one or more of the stays such that the handle, stays, and other frame components collapse and lie in a common plane. This collapsibility improves the portability of the luggage bag when the internal volume of the luggage bag is not used to store items.

What is claimed is: 
     
         1 . A collapsible luggage bag system, comprising:
 a bag having an internal volume;   a frame selectively interconnected to an exterior surface of said bag, including:

 a channel on said handle, said channel oriented along said longitudinal length of said handle, wherein opposing protrusions on said upper ends of said stays are positioned in recesses in said channel such that said upper ends of said stays slide along said longitudinal length of said handle.   
     
     
         4 . The collapsible luggage bag system of  claim 1 , further comprising:
 a channel on said handle, said channel oriented along said longitudinal length of said handle, wherein a protrusion on said upper end of said first stay and a protrusion on said upper end of said second stay are positioned in said channel such that said upper ends of said stays slide along said longitudinal length of said handle.   
     
     
         5 . The collapsible luggage bag system of  claim 1 , wherein said first stay and said second stay each comprise a plurality of telescoping elements which allow selective retraction and extension of said stays. 
     
     
         6 . The collapsible bag system of  claim 5 , further comprising:
 a clamp that selectively fixes relative positions of two elements of said plurality of telescoping elements.   
     
     
         7 . The collapsible luggage bag system of  claim 1 , wherein said first stay extends upwardly from said bag, and has an inwardly orientated arcuate shape. 
     
     
         8 . The collapsible luggage bag system of  claim 1 , wherein said first stay and said second stay are symmetric to each other about a vertical plane that bisects said bag. 
     
     
         9 . The collapsible luggage bag system of  claim 1 , further comprising:
 a first hubless wheel on said first stay, wherein said first hubless wheel is configured to lie in said substantially common plane with said frame and is sized to be stored in said internal volume of said bag; and   a second hubless wheel on said second stay, wherein said second hubless wheel is configured to lie in said substantially common plane with said frame and is sized to be stored in said internal volume of said bag.   
     
     
         10 . A method of storing a luggage frame in a collapsible luggage bag, comprising:
 providing a first stay having a retracted position and an extended position;   providing a second stay having a retracted position and an extended position;   providing a handle slideably interconnected to an upper end of said first stay and an upper end of said second stay, said upper ends of said stays slide along a longitudinal length of said handle as said stays move between said retracted positions and said extended positions;   disconnecting said first stay from said handle and repositioning said handle against said second stay; and   folding said first and second stays against a bottom frame member, wherein said first stay, said second stay, said bottom frame member, and said handle are repositioned in a substantially common plane to allow positioning in the perimeter confines of a bag.   
     
     
         11 . The method of  claim 10 , further comprising:
 selectively interconnecting said luggage frame to at least one attachment point on an exterior surface of said bag.   
     
     
         12 . The method of  claim 10 , further comprising:
 positioning a slideable element in a channel on said handle, said channel oriented along said longitudinal length of said handle, wherein said upper ends of said stays are rotatably interconnected to said slideable element.   
     
     
         13 . The method of  claim 10 , further comprising:
 sliding opposing protrusions on said upper ends of said stays in recesses in a channel on said handle such that said upper ends of said stays slide along said longitudinal length of said handle, wherein said channel is oriented along said longitudinal length of said handle.   
     
     
         14 . The method of  claim 10 , further comprising:
 sliding a protrusion on said upper ends of said stays in a channel on said handle such that said upper ends of said stays slide along said longitudinal length of said handle, wherein said channel is oriented along said longitudinal length of said handle.   
     
     
         15 . The method of  claim 10 , wherein said first stay and said second stay each comprise a plurality of telescoping elements which allow selective retraction and extension of said stays.
