A wheeled luggage item includes a collapsible bar assembly for stably supporting a secondary bag on top of the luggage item. The collapsible bar assembly includes a base mounted on top of the luggage and a generally U-shaped bar member having two ends respectively pivoted to the base. The bar member can be pivoted between a collapsed position, at which the bar member rests against the base, and an extended position, at which the bar member extends outwardly at an angle of about 90° to the base. Releasable locking means disposed on the base lock the bar member at the collapsed position. A push-button releases the bar member from the collapsed position, and an elastic member captured between the base and the bar member biases the bar member upward away from the collapsed position.

1. A wheeled luggage item, comprising:a case having wheels at the lower end thereof and a pull handle at the upper end thereof; a base mounted on the upper end of the luggage item; a bar member pivoted on said base for movement between a collapsed position, at which a substantial portion of the bar
1. A wheeled luggage item, comprising:a case having wheels at the lower end thereof and a pull handle at the upper end thereof; a base mounted on the upper end of the luggage item; a bar member pivoted on said base for movement between a collapsed position, at which a substantial portion of the bar member rests against said base, and an extended position, at which a substantial portion of the bar member extends outwardly from said base, said bar member having a greater extent transversely of said case than said pull handle; means for releasably locking said bar member at the collapsed position; and said bar member, when in said extended position, providing a supporting surface for stably supporting a secondary bag on top of the wheeled luggage item. 2. The luggage item of claim 1, wherein said bar member comprises a U-shaped bar having a pivotal connection at each end thereof to said base.3. The luggage item of claim 1, wherein said base includes a channel, at least a part of said bar member being received within said channel in the collapsed position.4. The luggage item of claim 2, wherein said base includes a block wall adjacent to each of said pivotal connections against which said bar member bears when in the extended position.5. The luggage item of claim 1, further comprising an elastic member, disposed between said base and said bar member, by which said bar member is biased outwardly away from said base after it is released from said collapsed position.6. The luggage item of claim 5, wherein said elastic member comprises a generally V-shaped elastic member having first and second legs resiliently connected at one end thereof by a control section, wherein said first arm rests against said base and, in the collapsed position of said bar member, said bar member compresses said second arm towards said base.7. The luggage item bar assembly of claim 6, wherein said releasable locking means includes a button on said base, a cantilevered arm extending outwardly along a lateral side of said button, and a hook at the free end of said cantilevered arm.8. The luggage item of claim 7, further comprising a base plate mounted on said base, said base plate having a post thereon, and a compression spring operatively interposed between said post and the closed end of said V-shaped elastic member.9. The luggage item of claim 2, wherein each pivotal connection includes a pivot member on said bar member, said base includes two chases in which respective ones of said two pivot members are received, and a pivot pin for pivotally connecting each of said pivot members and said base.10. The luggage item of claim 9, wherein:each of said pivot connections comprises a cylindrical surface on the end of said bar member; and each of said cylindrical surfaces is received within one of said chases. 11. The luggage item of claim 1, wherein said base comprises a first sub-base and a second sub-base, said first sub-base having a channel and a chase disposed at each end of said channel, said bar member including a pivot connecting member at each end thereof, one of said pivot connecting members being received in each chase, a pivot pin carried by each said pivot connecting member, and a bore in a side wall of each chase for receiving the respective pivot pin.12. The luggage item of claim 11, wherein said first sub-base includes an opening connected to a gap in said channel, a button including an arm cantilevered thereto at one end and having two hooks at the free end thereof, a base plate including a post on which said button bears, said base plate being mounted between said first sub-base and said second sub-base such that said button extends out of said opening and said hooks extend out of said gap.13. The luggage item of claim 12, further comprising an elastic member, one end of which rests against said cantilevered arm, the other end of which extends out of said gap.14. The luggage item of claim 1, wherein said pull handle comprises a single-tubed retractable handle, one end of which fastened to said case, the other end of which extends upwardly out of the top of said case and includes a handgrip at the distal end thereof.15. A wheeled luggage item, comprising:a case having wheels at the lower end thereof and a pull handle at the upper end thereof; a base mounted on the upper end of the luggage item; a bar member pivoted on said base for movement between a collapsed position, at which a substantial portion of the bar member rests against said base, and an extended position, at which a substantial portion of the bar member extends outwardly from said base, said bar member having a greater extent transversely of said case than said pull handle; means for releasably locking said bar member at the collapsed position; and said bar member, when in said extended position, providing a supporting surface for stably supporting a secondary bag on top of the wheeled luggage item while the wheeled luggage item is pulled on the wheels. 16. A wheeled luggage item, comprising:a case having wheels at the lower end thereof and a pull handle at the upper end thereof; a base mounted on the upper end of the luggage item; a bar member pivoted on said base for movement between a collapsed position, at which the bar member rests against said base, and an extended position, at which the bar member extends outwardly from said base, said bar member having a greater extent transversely of said case than said pull handle; means for releasably locking said bar member at the collapsed position; and said bar member, when in said extended position, providing a supporting surface for stably supporting a secondary bag on top of the wheeled luggage item; wherein said bar member comprises a U-shaped bar having a pivotal connection at each end thereof to said base. 17. A wheeled luggage item, comprising:a case having wheels at the lower end thereof and a pull handle at the upper end thereof, a base mounted on the upper end of the luggage item; a bar member pivoted on said base for movement between a collapsed position, at which the bar member rests against said base, and an extended position, at which the bar member extends outwardly from said base, said bar member having a greater extent transversely of said case than said pull handle; means for releasably locking said bar member at the collapsed position; and said bar member, when in said extended position, providing a supporting surface for stably supporting a secondary bag on top of the wheeled luggage item; an elastic member, disposed between said base and said bar member, by which said bar member is biased outwardly away from said base after it is released from said collapsed position.
