Abstract

A rolling luggage bag includes a cover fixedly coupled to a base, the base including a first side opposite a second side and a bottom face extending there between, wherein the cover comprises a plurality of panels, arranged in a direction away from the base, wherein the plurality of panels defines an interior chamber, the interior chamber comprising an internal cover fixedly attached to the panels of the fifth panel zone, 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.

First claim

The invention claimed is:

1. A rolling luggage bag comprising:
a cover fixedly coupled to a base, the base including a first side opposite a second side and a bottom face extending there between;
wherein the cover comprises a plurality of panels, arranged in a direction away from the base,
wherein 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;
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;
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;
wherein the plurality of panels defines an interior chamber, the interior chamber comprising an internal cover fixedly attached along only one seam to the panels of the fifth panel zone;
wherein the internal cover fits only within a top portion of the interior chamber; and
wherein the internal cover comprises a vertical height between 15 cm to 30 cm.

2. The rolling luggage bag of claim 1 , wherein the vertical height is 15 cm, 16 cm, 17 cm, 18 cm, 19 cm, 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, 25 cm, 26 cm, 27 cm, 28 cm, 29 cm, or 30 cm.

3. The rolling luggage bag of claim 1 , wherein the internal cover comprises a perimeter draw string mechanism, wherein the perimeter draw string mechanism comprises a string, a cord, a rope, a cord lock, a hem, a casing, or loops.

4. The rolling luggage bag of claim 1 , wherein the internal cover comprises fabric, foam, mesh, or other suitable padding material.

5. The rolling luggage bag of claim 1 , wherein the internal cover comprises a thickness ranging between 0.05 cm and 2.0 cm.

6. The rolling luggage bag of claim 1 , wherein the fourth panel zone comprises an angled side edge at approximately half of a height of the fourth panel zone.

7. The rolling luggage bag of claim 1 , wherein the rolling luggage bag further comprises a plurality of rail members positioned in the second panel zone, and a plurality of rail extensions positioned on the base, wherein when the rolling luggage bag is in an upright position each rail member engages one of the pluralities of rail extensions to form a bumper that extends from the base along a portion of the cover.

8. The rolling luggage bag of claim 1 , wherein the rolling luggage bag is pivotable about the axis of rotation into a titled position such that the first and second wheels are in rolling contact with a surface, and the third and fourth wheels are removed from rolling contact with the surface, and wherein the rolling luggage bag is movable along the surface in a tilted position.

9. The rolling luggage bag of claim 1 , wherein when the rolling luggage bag is in an upright position, the first, second, third, and fourth wheels all contact a surface the rolling luggage bag stands on.

10. The rolling luggage bag of claim 1 , wherein the panels of the first panel zone are rectangular in shape and the panels of second panel zone are square in shape, wherein the square shape is defined by two separate triangular panels having an angled fold there between.

11. The rolling luggage bag of claim 1 , wherein the panels of the third, fourth, and fifth panel zones are trapezoidal in shape.

12. The rolling luggage bag of claim 1 , wherein the panels of the first panel zone have a greater stiffness than the panels of the second panel zone.

13. A collapsible luggage bag 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; wherein the back portion, first side portion, second side portion, and front flap comprise a plurality of panels,
wherein 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, wherein 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 second panel zone has a storage pocket, wherein the fourth panel zone has a plurality of second handles, wherein the first and second side portions pivot away from each other about respective folds between the respective side portion and the back portion when the front flap is at least partially removed;
wherein the base comprises a first side opposite a second side and a bottom face extending therebetween;
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;
wherein the plurality of panels defines an interior chamber, the interior chamber comprising an internal cover fixedly attached along only one seam to the panels of the fifth panel zone;
wherein the internal cover fits only within a top portion of the interior chamber; and
wherein the internal cover comprises a thickness ranging between 0.5 and 1.5 cm.

14. The collapsible luggage bag of claim 13 , wherein the internal cover comprises a perimeter draw string mechanism, wherein the perimeter draw string mechanism comprises a string, a cord, a rope, a cord lock, a hem, a casing, or loops.
