Collapsible duffle bag
A collapsible item of luggage is provided comprising a rigid back wall. Three non-rigid sidewalls are attached the rigid back wall and to one another to form a rectangular box. An end panel is pivotally attached to a first end of the rectangular box. A retention flange is attached to one of the back wall or the end panel. Finally, a retention rod is attached to the other of the back wall or the end panel. The retention rod is removably attachable to the retention flange such that when the retention rod is attached to the retention flange the end panel is held in an extended position generally directed away from the back wall and when the retention rod is not attached to both retention flanges the end panel may be pivoted to a collapsed position generally adjacent and parallel to the back wall.
The present invention claims priority to U.S. Provisional Patent Application No. 60/495,201 filed Aug. 14, 2003 entitled “Collapsible Duffel Bag” the contents of which are expressly incorporated herein by reference.
BACKGROUND OF THE INVENTIONA. Field of the invention
The invention relates to the field of luggage. More specifically, the invention relates to an article of luggage having collapsible rigid walls.
B. Description of Related Art
In the past both hard-sided and soft-sided luggage has been known. Previously soft-sided duffle bags and suitcases have been known. Soft-sided duffle bags and suitcases have several advantages over hard sided bags and cases, such as ease of storage and generally lighter weight than their hard-sided counterparts. However, hard sided bags and cases protect their contents from crushing from stacking of bags and cases upon one another and mishandling by attendants. However, hard sided cases are more difficult to store and merchandise due to their inability to reduce their size when unfilled. Therefore, there is a need for a bags and cases which combine the relative advantages of hard sided and soft sided luggage.
SUMMARY OF THE INVENTIONA collapsible item of luggage is provided comprising a rigid back wall. Three non-rigid sidewalls are attached the rigid back wall and to one another to form a rectangular box. An end panel is pivotally attached to a first end of the rectangular box. A retention flange is attached to one of the back wall or the end panel. Finally, a retention rod is attached to the other of the back wall or the end panel. The retention rod is removably attachable to the retention flange such that when the retention rod is attached to the retention flange the end panel is held in an extended position generally directed away from the back wall and when the retention rod is not attached to both retention flanges the end panel may be pivoted to a collapsed position generally adjacent and parallel to the back wall.

Claims
1. A collapsible item of luggage comprising:
- a rigid back wall;
- three non-rigid sidewalls attached the rigid back wall and to one another to form a rectangular box;
- an end panel pivotally attached to a first end of the rectangular box;
- a retention flange attached to one of the back wall or the end-panel;
- a retention rod attached to the other of the back wall or the end panel, the retention rod removably attachable to the retention flange such that when the retention rod is attached to the retention flange the end panel is held in an extended position generally directed away from the back wall and when the retention rod is not attached to both retention flanges the end panel may be pivoted to a collapsed position generally adjacent and parallel to the back wall.
2. The item of luggage of claim 1 wherein the attachment of the retention rod to the other of the back wall or the end panel is accomplished by a removable attachment of the retention rod to an attachment flange.
3. The item of luggage of claim 2 further comprising a second retention flange attached to the back wall and a second retention flange attached to the end panel, wherein a second retention rod is attachable to each of second retention flange of the back wall and the second retention flange of the end panel, the second retention rod being associated with the second retention flanges to cooperate with the other retention rod, such that when the both retention rods are attached to their respective retention flanges the end panel is held in the extended position and when both retention rods are not attached to their respective retention flanges the end panel may be pivoted to the collapsed position.
4. The item of luggage of claim 1 wherein the retention flange comprises a generally arcuate portion having protuberance on an interior portion thereof and the retention rod comprises at least one end portion having a reduced diameter section that cooperates with the protuberance to maintain the retention rod in a detachable association with the flange.
5. The item of luggage of claim 4 wherein the end portion of the retention rod is turned approximately ninety degrees with respect to the retention rod.
6. The item of luggage of claim 4 wherein the retention rod comprises a second end portion having a reduced diameter section that cooperates with the protuberance to maintain the second end of the retention rod in a detachable association with the associated retention flange.
7. The item of luggage of claim 1 further comprising a second end panel pivotally attached to a second end of the rectangular box opposite the first end.
8. The item of luggage of claim 7 wherein the second end panel comprises a retention flange that is removably attached to a second retention rod, the second retention rod attached to the back wall wherein the retention rod attached to the second end panel, the second end panel is held in an extended position generally directed away from the back wall and when the retention rod is not attached the second end panel, the second end panel is pivotable to a collapsed position generally adjacent and parallel to the back wall.
9. The item of luggage of claim 1 further comprising a retractable handle.
