Abstract

Official abstract text for this publication.

A rolling luggage bag includes a cover coupled to a base, the base including a first side opposite a second side and a bottom face extending there between, a first wheel and a second wheel coupled to the base, the first and second wheels configured to rotate about an axis of rotation and separated by a first distance along the axis of rotation, at least a portion of each of the first and second wheels projecting from the first side and from the bottom face, and a third wheel and a fourth wheel coupled to the bottom face, the third and fourth wheels configured to independently swivel about a respective swivel axis and separated by a second distance extending between the swivel axes. When the rolling luggage is in an upright position, the first, second, third, and fourth wheels all contact a surface the luggage bag stands on.

Opening claim text (preview).

The invention claimed is: 1. A collapsible luggage bag comprising: a cover comprising: a back portion connected to a first side portion and a second side portion; a front flap removably connected to the first side portion, the second side portion, and the back portion by a connection member; a base connected to the back portion, the first side portion, the second side portion, and the front flap, wherein: the base is fixedly connected to the back portion, the first side portion, the second side portion, and the front flap; the front flap, the back portion, the first side portion, and the second side portion define an interior chamber for receiving items for transport; the back portion, the first side portion, the second side portion, and the front flap, comprise a plurality of panels; the plurality of panels comprises a first panel zone proximate the base, a second panel zone adjacent the first panel zone in a direction away from the base, a third panel zone adjacent the second panel zone in a direction away from the base, a fourth panel zone adjacent the third panel zone in a direction away from the base, and a fifth panel zone adjacent the fourth panel zone in a direction away from the base; each of the panel zones extends around a circumference defined by a portion of the back portion, first side portion, second side portion, and the front flap, wherein: the panels of the first panel zone are rectangular in shape; the panels of the second panel zone are square in shape, wherein the square shape is defined by two separate triangular panels having an angled fold there between; the second panel zone includes an arcuate portion of the front flap; the panels of the third, fourth, and fifth panel zones are trapezoidal in shape; the front flap is selectively disconnected from the back portion, the first side portion, and the second side portion to allow any desired number of panel zones to bend or fold over a desired fold in the front flap and thereby provide varying amounts of access to the interior chamber, wherein: a first access opening position is defined when the collapsible luggage bag is in an upright position, and the connection member partially disengages with the first and second side portions, thereby partially exposing the interior chamber; and a second access opening position is defined when the connection member fully disengages with the first and second side portions so that the front flap is no longer connected with the back portion the first side portion, and the second side portion, thereby fully exposing the interior chamber. 2. The collapsible luggage bag of claim 1 , wherein: in the first access opening position, the first side portion and the second side portion pivot away from each other about a respective fold between a respective side portion; and the back portion, the first side portion, the second side portion, and the back portion define a butterfly opening to provide maximum access to the interior chamber. 3. The collapsible luggage bag of claim 2 , wherein the butterfly opening allows for unobstructed insertion of a large or bulky item into the interior chamber. 4. The collapsible luggage bag of claim 1 , wherein in the second access opening position, the front flap remains connected to the base. 5. The collapsible luggage bag of claim 1 , wherein in the first access opening position, a user may place and position an item into the interior chamber while the collapsible luggage bag remains in an upright position. 6. The collapsible luggage bag of claim 1 , wherein the second panel zone comprises a storage pocket, and the fourth panel zone comprises a plurality of handles. 7. The collapsible luggage bag of claim 1 , further comprising: a first wheel and a second wheel coupled to the base, the first and second wheels configured to rotate about an axis of rotation and separated by a first distance along the axis of rotation, at least a portion of each of the first and second wheels projecting from a first side of the base and from a bottom face of the base; and a third wheel and a fourth wheel coupled to the bottom face, the third and fourth wheels configured to independently swivel about a respective swivel axis and separated by a second distance extending between the respective swivel axes. 8. The collapsible luggage bag of claim 1 , wherein the back portion is formed integrally with the first side portion and the second side portion. 9. The collapsible luggage bag of claim 1 , wherein the connection member comprises a first portion that separates the front flap from the first side portion, and a second portion that separates the front flap from the second side portion. 10. A collapsible luggage bag comprising: a cover comprising: a back portion connected to a first side portion and a second side portion; a front flap removably connected to the first side portion, the second side portion, and the back portion by a connection member; a base connected to the back portion, the first side portion, the second side portion, and the front flap, wherein: the base is fixedly connected to the back portion, the first side portion, the second side portion, and the front flap; the back portion, the first side portion, the second side portion, and the front flap, comprise a plurality of panels; the plurality of panels comprises a first panel zone proximate the base, a second panel zone adjacent the first panel zone in a direction away from the base, a third panel zone adjacent the second panel zone in a direction away from the base, a fourth panel zone adjacent the third panel zone in a direction away from the base, and a fifth panel zone adjacent the fourth panel zone in a direction away from the base; each of the panel zones extends around a circumference defined by a portion of the back portion, first side portion, second side portion, and the front flap, wherein: the panels of the first panel zone are rectangular in shape; the panels of the second panel zone are square in shape, wherein the square shape is defined by two separate triangular panels having an angled fold there between; the second panel zone includes an arcuate portion of the front flap; the panels of the third, fourth, and fifth panel zones are trapezoidal in shape; each of the plurality of panels are interconnected via an outer shell, wherein the outer shell comprises a plurality of pockets, wherein each pocket receives a respective panel, and a fold is formed between adjacent pockets; the front flap is selectively disconnected from the back portion, the first side portion, and the second side portion to allow any desired number of panel zones to bend or fold over a desired fold in the front flap; the front flap is fully disconnected from the back portion, the first side portion, and the second side portion to move the collapsible luggage bag from an upright position to a collapsed position, wherein: the front flap is folded along the folds between adjacent panels and received by the base, the first side portion and the second side portion are each bent along a respective angled fold such that the panels of the first panel zone are received by the base, and the first side portion and the second side portion fold inward toward the back portion and do not overlap; and a remainder of the cover folds along the folds and is received in the base. 11. The collapsible luggage bag of claim 10 , wherein the base comprises an inside surface that defines a planar or substantially flat receiving surface substantially free of protrusions or other structural obstructions that may interfere with receipt of items into the inside surface of the base. 12.
