[0002] The present disclosure relates to a rotatable foldable travel luggage carrier, and more specifically, to a luggage carrier that can be folded so as to be easier to carry during use and require less storage footprint when not in use, and has an enlarged access opening to facilitate the arrangement and positioning of the contents placed in the luggage carrier, and relates to a wheeled travel luggage carrier.

Background Art

[0003] Rotating travel luggage carriers are generally known in the art. However, known rotating travel luggage carriers have certain limitations. For example, existing luggage carriers typically include three or more swivel caster wheels that allow the luggage carrier to roll in any direction while in the upright position. Although convenient, the wheels that engage the ground or floor are only swivel caster wheels, and there is nothing to stop the unintentional rotation or rolling of these wheels, so the luggage carrier is prone to moving in an unintended direction.

[0004] As another limitation, existing luggage carriers typically define an internal chamber by rigid or relatively inflexible sides, back, and / or front. For example, the front may open away from the rest of the rigid portion to provide an access opening to the internal chamber. While the rigid portion provides protection for the contents inside, it inhibits the insertion of large or otherwise bulky objects, such as a golf bag containing a set of golf clubs. To place a large or bulky object into the internal chamber, the user must insert the object into the access opening at an angle to the luggage carrier, or at other awkward angles. Also, during insertion, the user may need to change the angle between the object and the luggage carrier several times to avoid contact with the rigid portion until the object enters the internal chamber. Changing the angle several times is cumbersome, difficult, and inconvenient for the user.

[0005] As yet another limitation, some types of existing luggage carriers include side wheels and a handle provided on the top of the luggage carrier. The user can grip the handle, tilt the luggage carrier to engage the side wheels with the ground, and freely roll the luggage carrier in the tilted position. However, since most of the load of the luggage carrier is transmitted to the user via the top handle, it places a burden on the user's arm, wrist, and / or forearm. Summary of the Invention Means for Solving the Problems

[0006] The rotatable luggage bag includes a cover coupled to a base, the base comprising a first side opposite the second side and a bottom surface extending therebetween, and a cover, and first and second wheels coupled to the base, the first and second wheels being configured to rotate about an axis of rotation and being spaced apart from each other by a first distance along the axis of rotation, at least a portion of each of the first and second wheels protruding from the first side and from the bottom surface, the first wheel and the second wheel, and third and fourth wheels coupled to the bottom surface, the third and fourth wheels being configured to pivot independently about their respective pivot axes and being spaced apart from each other by a second distance extending between the pivot axes, the third wheel and the fourth wheel. When the rotatable luggage carrier is in the upright position, all of the first, second, third, and fourth wheels contact the surface on which the luggage bag stands.

[0007] In other embodiments, the foldable luggage bag can include a back connected to a first side and a second side, and a front flap removably connected to the first side, the second side, and the back by a connecting member, and a base connected to the back and the front flap and optionally removable from the first side and the second side. The first and second sides pivot away from each other about respective folds between each side and the back when the front flap is removed.

[0008] Other features and aspects will become apparent by considering the following detailed description and the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

[0055] Before any embodiments of the present disclosure are described in detail, it is to be understood that the present disclosure is not limited in its application to the details of construction or the arrangement of components set forth in the following description or illustrated in the drawings. The present disclosure is capable of supporting other embodiments and of being practiced or carried out in various ways. It is to be understood that the description of specific embodiments is not intended to limit the present disclosure to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure. Also, it is to be understood that the language and terminology used herein are for the purpose of description and should not be regarded as limiting.

[0056] For ease of discussion and understanding, and for purposes of illustration only, in the following detailed description, the rotatable luggage bag 10 is exemplified as an elongated luggage bag suitable for carrying large items such as a golf bag, golf clubs, and one or more golf accessories. The golf bag is sized to carry a set of golf clubs including one or more combinations of a plurality of full-length golf clubs, such as a driver, wood, hybrid, iron, wedge, and / or putter. The full-length golf clubs are not foldable and have a length of from about 32 inches to about 49 inches depending on the club. Examples of large golf accessories include a full-length golf umbrella, which has a length of from about 36 inches to about 48 inches and opens to an arc or canopy size of from about 50 inches to 68 inches or more. The elongated luggage bag is provided for purposes of illustration, and it is to be understood that aspects of the luggage bag 10 disclosed herein may be incorporated into luggage of any size, shape, or orientation.

[0057] Figure 1 shows a rotatable luggage bag 10. The luggage bag 10 includes a base 14 connected to a cover 18. As shown in FIGS. 2-6, the cover 18 includes a front portion 22 (or front flap), a back portion 26 (or back flap), a first side portion 30 (flap 30), and a second side portion 34 (or flap). The front portion 22 faces opposite the back portion 26, and the first side portion 30 faces opposite the second side portion 34. Further, the back portion 26 is connected to or otherwise integrally formed with the first side portion 30 and the second side portion 34. The front portion 22 may have a selectively removable connection with the back portion 26, the first side portion 30, and the second side portion 34 to open or provide access to the interior chamber of the luggage bag 10. The selectively removable connection between the front portion 22 and the back portion 26, the first side portion 30, and the second side portion 34 may provide different degrees or amounts of access to the interior chamber of the luggage bag 10. In other words, the removable connection may provide an opening or a partial opening to the interior chamber. For example, the selectively removable connection may be formed by a zipper having a pair of sliders 100a, 100b that connect at a closed position at the top or end of the luggage bag 10 opposite the base 14 (see FIGS. 4A-B). The sliders 100a, 100b may be moved in opposite directions along a portion of the zipper to provide partial access to the interior chamber, such as in the first upright access position shown in FIG. 8, or may be moved along the entire zipper to provide maximum access to the interior chamber, such as in the second access position shown in FIG. 9.

[0058] The front portion 22, the back portion 26, the first side portion 30, and the second side portion 34 are each formed of a plurality of panels interconnected by an outer shell 38 (see FIG. 16). In most embodiments, the outer shell 38 is formed of cloth or other fabric. For example, the fabric may be polyester, nylon, canvas, denim, or any other fabric material suitable for use in duffel-type applications. In each of the portions 22, 26, 30, 34, the outer shell 38 includes seams for sealing the outer shell 38 and defining a plurality of pockets, each pocket receiving a respective panel. Fold lines 42 are formed between adjacent pockets of each of the portions 22, 26, 30, 34 (see FIGS. 1 to 9 and FIG. 16). To form the fold lines 42, seams are provided at desired fold line positions of the outer shell 38 of each of the portions 22, 26, 30, 34. In other embodiments, the fold lines 42 may be formed in any other suitable or desired manner to facilitate folding of each of the portions 22, 26, 30, 34. The fold lines 42 are provided not only between adjacent or consecutive panels within each of the portions 22, 26, 30, 34, but also generally between adjacent or consecutive panels between each of the portions 26, 30, 34.

[0059] Referring to FIGS. 7A through 7D, in the state where the outer shell 38 is removed, a plurality of panels 46 are illustrated for each of the portions 22, 26, 30, 34. In most embodiments, each panel 46 is a polyethylene board material [(C2H2) nIt is formed of [[H2]], a foaming material, a cloth material, or a combination thereof. The polyethylene board material may be any industry standard grade including, but not limited to, ultra-high molecular weight polyethylene (UHMWPE), ultra-low molecular weight polyethylene (ULMWPE), high molecular weight polyethylene (HMWPE), high density polyethylene (HDPE), high density cross-linked polyethylene (HDXLPE), cross-linked polyethylene (PEX), medium density polyethylene (MDPE), linear low density polyethylene (LLDPE), low density polyethylene (LDPE), very low density polyethylene (VLDPE), and chlorinated polyethylene (CPE). In other embodiments, panel 46 may be formed of polyurethane, acrylonitrile butadiene styrene, combinations thereof, or any other suitable material.

[0060] The panels 46 of each of the portions 22, 26, 30, 34 are arranged in a panel zone, panel ring, or bands stacked horizontally or arranged in a direction away from the base 14. The panel zone 50 extends generally around the periphery of the luggage bag 10. Depending on the position along the panel zone 50 and each of the portions 22, 26, 30, 34, any of the panels 46 may be formed of different materials (e.g., a foaming material, a board material, or a combination of a foaming material and a board material), have different panel thicknesses, and / or have different panel rigidities or hardnesses.

[0061] The first or bottom panel zone 50a is located along the base of each of the portions 22, 26, 30, 34 and has a first panel height or length H1 measured vertically (perpendicular to the ground plane) when the luggage bag 10 is in the upright position. In some embodiments, the first panel height H1 is less than about 15 cm. The first panel height H1 can be about 5.0 cm, about 5.5 cm, about 6.0 cm, about 6.5 cm, about 7.0 cm, about 7.5 cm, about 8.0 cm, about 8.5 cm, about 9.0 cm, about 9.5 cm, about 10.0 cm, about 10.5 cm, about 11.0 cm, about 11.5 cm, about 12 cm, about 12.5 cm, about 13.0 cm, about 13.5 cm, about 14.0 cm, about 14.5 cm, or about 15.0 cm. In an exemplary embodiment, the first panel height H1 is about 6.5 cm. In other embodiments, the first panel height H1 can be less than 6.5 cm, less than 6.4 cm, less than 6.3 cm, less than 6.2 cm, less than 6.1 cm, or less than 6.0 cm based on the size, shape, or orientation of the luggage bag 10. In other embodiments, the first panel height H1 can be greater than 6.5 cm, 6.6 cm, 6.7 cm, 6.8 cm, 6.9 cm, or 7.0 cm based on the size, shape, or orientation of the luggage bag 10. The first panel zone 50a comprises a panel 46a formed of a rigid board material having a thickness of about 1.75 mm. In some embodiments, the panel 46a of the first panel zone 50a is rectangular, but in other embodiments, it can be of any suitable or desired shape or combination of shapes. For example, the panel 46a of the first panel zone 50a can be inclined or the height H1 (see FIG. 3) can taper to conform to the base 14. The panel 46a of the first panel zone 50a engages or otherwise connects to the base 14 (see FIG. 3).

[0062] Adjacent to the first panel zone 50a in a direction away from the base 14 is a second panel zone 50b along each of the portions 22, 26, 30, 34. The second panel zone 50b has a second panel height or length H2 measured vertically (perpendicular to the ground plane) when the luggage bag 10 is in the upright position.

The front portion 22 of the second panel zone 50b includes a panel 46b. The back portion 26, the first side portion 30, and the second side portion 34 of the second panel zone 50b comprise a panel 46b formed of a relatively rigid board material combined with a foam. In many embodiments, the rigid board material has a thickness of about 2.5 mm. By disposing the panel 46b in the vicinity of or approximating the position of the base 14, the back portion 26, the first side portion 30, and the second side portion 34 are structurally supported while the luggage bag 10 is in the upright position, as shown in FIG. 8.

[0063] In some embodiments, the panels of the second panel zone 50b of the front portion 22 and the back portion 26 generally have a rectangular shape, while the panels of the first side portion 30 and the second side portion 34 generally have a square shape, which square shape is defined by two separate triangular panels having angled folds 42a therebetween that facilitate the foldability of the cover 18 (discussed in more detail below). In some embodiments, the panels of the first side portion 30 and the second side portion 34 generally have a trapezoidal shape. In other embodiments, the panels of the second panel zone 50b may be of any suitable or desired shape or combination of shapes.

[0064] Adjacent to the second panel zone 50b in a direction away from the base 14, there is a third panel zone 50c along each of the portions 22, 26, 30, 34. The third panel zone 50c has a third panel height or length H3 measured vertically (perpendicular to the ground surface) when the luggage bag 10 is in the upright position. In some embodiments, the third panel height or length H3 can be 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, 25 cm, 26 cm, 27 cm, 28 cm, 29 cm, 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, 35 cm, 36 cm, 37 cm, 38 cm, 39 cm, or 40 cm. In one exemplary embodiment, the third panel height H3 is approximately 32 cm. In other embodiments, the third panel height H3 can be less than 30 cm, 29 cm, 28 cm, 27 cm, 26 cm, or 25 cm based on the size, shape, or orientation of the luggage bag 10. In other embodiments, the third panel height H3 can be greater than 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, or 35 cm based on the size, shape, or orientation of the luggage bag 10. The front portion 22 and the side portions 30, 34 of the third panel zone 50c each comprise a panel 46c formed of a relatively rigid board material combined with a foam. In many embodiments, the rigid board material has a thickness of about 1.0 mm. The back portion 26 of the third panel zone 50c comprises the panel 46a as described above. In some embodiments, the panels of the third panel zone 50c of the front portion 22, the back portion 26, the first side portion 30, and the second side portion 34 generally have a trapezoidal shape. In other embodiments, the panels of the third panel zone 50c in the front portion 22, the back portion 26, the first side portion 30, and the second side portion 34 generally have a rectangular shape. In other embodiments, the panels of the third panel zone 50c can be of any suitable or desired shape or combination of shapes.

[0065] The fourth panel zone 50d is adjacent to the third panel zone 50c in a direction away from the base 14 along each of the portions 22, 26, 30, 34 and has a fourth panel height or length H4 measured vertically (perpendicular to the ground plane) when the luggage bag 10 is in the upright position. In some embodiments, the fourth panel height or length H4 can be 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, 25 cm, 26 cm, 27 cm, 28 cm, 29 cm, 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, 35 cm, 36 cm, 37 cm, 38 cm, 39 cm, or 40 cm. In one exemplary embodiment, the fourth panel height H4 is about 32 cm. In other embodiments, the fourth panel height H4 can be less than 30 cm, 29 cm, 28 cm, 27 cm, 26 cm, or 25 cm based on the size, shape, or orientation of the luggage bag 10. In other embodiments, the fourth panel height H4 can be greater than 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, or 35 cm based on the size, shape, or orientation of the luggage bag 10. In many embodiments, the fourth panel zone 50d is substantially the same as the third panel zone 50c with respect to the type, position, and shape of the panel.

[0066] At the top of each of the portions 22, 26, 30, 34 that are farthest from the base 14, there is a fifth panel zone or upper panel zone 50e. The back 26, the first side 30, and the second side 34 of the upper panel zone 50e have a fifth panel height or length H5 measured vertically (perpendicular to the ground plane) when the luggage bag 10 is in the upright position. In some embodiments, the fifth panel height or length H5 can be 10 cm, 11 cm, 12 cm, 13 cm, 14 cm, 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. In one exemplary embodiment, the fifth panel height H5 is about 20 cm. In other embodiments, the fifth panel height H5 can be less than 30 cm, 29 cm, 28 cm, 27 cm, 26 cm, or 25 cm based on the size, shape, or orientation of the luggage bag 10. In other embodiments, the fifth panel height H5 can be greater than 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, or 25 cm based on the size, shape, or orientation of the luggage bag 10. In some embodiments, the back 26 includes a panel in the upper panel zone 50e that is generally trapezoidal in shape and has an edge 54. The first side 30 and the second side 34 each include a panel within the upper panel zone 50e that has respective arcuate edges 58a, 58b. In such embodiments, the arcuate edges 58a, 58b connect to the edge 54 of the back 26 (see FIGS. 8 and 9).

[0067] The front portion 22 of the upper panel zone 50e has a sixth panel height or length H6 that is measured vertically (perpendicular to the ground plane) when the luggage bag 10 is in the upright position. In many embodiments, the sixth panel height H6 is generally greater than the fifth panel height H5. In some embodiments, the sixth panel height or length H6 can be 28 cm, 29 cm, 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, 35 cm, 36 cm, 37 cm, 38 cm, 39 cm, 40 cm, 41 cm, 42 cm, 43 cm, 44 cm, 45 cm, 46 cm, 47 cm, or 48 cm. In one exemplary embodiment, the sixth panel height H6 is approximately 38.5 cm. In other embodiments, the sixth panel height H6 can be less than 40 cm, 39 cm, 38 cm, 37 cm, 36 cm, or 35 cm, based on the size, shape, or orientation of the luggage bag 10. In other embodiments, the sixth panel height H 6は , based on the size, shape, or orientation of the luggage bag 10, can be greater than 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, or 35 cm. In some embodiments, the panel within the zone 50e of the front portion 22 comprises a parabolic edge 62 that removably connects to the arcuate edges 58a, 58b and the edge 54, and the additional panel height H6 of the front portion 22 defines or forms a curved surface or arcuate surface 66 (see FIGS. 2 to 3) that extends beyond or overlaps a portion of the base ground area defined by the peripheral edge of the base 14. In such embodiments, the arcuate surface 66 is removably connected to the back 26, the first side 30, and the second side 34.

[0068] In some embodiments, the panel heights H1, H2, H3, and H4 vary across the front, back, first side, and second side. In some embodiments, when the luggage bag 10 is in the upright position, the front portion 22 is slightly angled after assembly, and the back portion 26 is substantially perpendicular to the ground surface. Due to the angled orientation of the front portion 22, as illustrated in FIG. 7D, when the front is laid flat, the height of the panel of the front portion 22 can be slightly greater than the height of the panels of the back portion 26, the first side portion 30, and the second side portion 34 (the difference in height is not visible in the illustration). Similarly, in some embodiments, the panel heights of the first side portion 30 and the second side portion 34 can be slightly greater than the panel height of the back portion 26. In some embodiments, the difference in height of the panel portions can be minimized to vary only by a length between 0 cm and 0.2 cm. However, in other embodiments, the fourth panel height H4 is greater at the front portion 22 than at the back portion 26 by a length between 1.5 cm and 3.5 cm. Embodiments similar to the embodiments of FIGS. 22 and 23 have a fourth panel 50d that forms an angle at the front portion 22. Accordingly, these embodiments have a greater difference in the fourth panel height H4 between sections.

[0069] The front portion 22 can have a width measured parallel to the fold line 42 from the point where the front portion 22 intersects the first side portion 30 to the point where the front portion 22 intersects the second side portion 34. The back portion 26 can have a width measured parallel to the fold line 42 from the point where the back portion 26 intersects the first side portion 30 to the point where the back portion 26 intersects the second side portion 34. In many embodiments, the width of the front portion 22 is the same as or similar to the width of the back portion 26 at any height.

[0070] The first width W1 of the back 26 is measured at the fold between the first panel zone 50a and the second panel zone 50b. The first width W1 can be in the range of 35 cm to 50 cm. In some embodiments, the first width W1 can be 35 cm, 36 cm, 37 cm, 38 cm, 39 cm, 40 cm, 41 cm, 42 cm, 43 cm, 44 cm, 45 cm, 46 cm, 47 cm, 48 cm, 49 cm, or 50 cm. In the illustrated embodiment, the first width W1 is approximately 43 cm. In many embodiments, the first width of the front part 22 is the same as or similar to the first width W1 of the back 26.

[0071] The second width W2 of the back 26 is measured at the fold between the second panel zone 50b and the third panel zone 50c. The second width W2 can be in the range between 35 cm and 50 cm, or between 35 cm and 40 cm. In some embodiments, the second width W2 can be 35 cm, 36 cm, 37 cm, 38 cm, 39 cm, 40 cm, 41 cm, 42 cm, 43 cm, 44 cm, 45 cm, 46 cm, 47 cm, 48 cm, 49 cm, or 50 cm.

[0079] The back portion 26 includes a panel 46c formed of a relatively rigid board material combined with a foam in the upper panel zone 50e. The rigid board material has a thickness of about 1.0 mm. The front portion 22, the first side portion 30, and the second side portion 34 include a panel 46d formed of a foam and not including a board material in the upper panel zone 50e. By forming the panel 46d from the foam, flexibility is imparted to the front portion 22, the first side portion 30, and the second side portion 34, facilitating the formation of the arcuate surface 66 (see FIGS. 2 to 3) of the front portion 22 in the upper panel zone 50e.

[0080] It should be understood that the greater the thickness of the board material, the harder or more rigid the panel will be. For example, the panel of the second panel zone 50b is harder and / or more rigid than the panel of the upper panel zone 50e. Generally, the overall rigidity or hardness of the panel decreases upward from the base 14 toward the arcuate surface 66.

[0081] The cover 18 can include a total of 15 to 30 panels 46. In some embodiments, the cover 18 includes a total of 15 to 20 panels, 17 to 25 panels, 20 to 25 panels, or 25 to 30 panels 46. For example, the cover 18 shown in FIG. 3 includes a total of 22 panels 46. In some embodiments, the cover 18 includes at least 20 panels, 21 panels, 22 panels, 23 panels, 24 panels, or 25 panels. In other embodiments, the cover 18 includes 25 panels, 24 panels, 23 panels, 22 panels, 21 panels, or 20 or fewer panels. The total number of panels may be based on the size, shape, and / or foldability of the luggage bag 10.

[0082] In one exemplary embodiment, the luggage bag 10 has a height or length of approximately 120.5 cm (or approximately 47.5 inches) defined by the sum of heights H1 to H5. In other embodiments, the luggage bag 10 may have a height or length in the range of approximately 110 cm to approximately 140 cm or more. In other words, the luggage bag 10 may have a height or length suitable for receiving a golf bag and / or one or more full-length golf clubs.

[0083] Referring back to FIGS. 1-6, the luggage bag 10 includes a plurality of handles 70 to assist in lifting or otherwise carrying the luggage bag 10. As shown in FIGS. 1 and 3, the first handle 70a is connected to the front portion 22 in the first panel zone 50a proximate to or in the vicinity of the base 14 to provide a location for the user to grip near the base 14. Referring to FIGS. 1-6, a plurality of second handles 70b, 70c, 70d, 70e are connected to the front portion 22, the back portion 26, the first side portion 30, and the second side portion 34, respectively. The second handles 70b, 70c, 70d, 70e are shown at a position from about 70 cm to 90 cm from the base 14 (or the surface on which the base 14 is disposed) within the same horizontal plane around the luggage bag 10. In other embodiments, the second handles 70b, 70c, 70d, 70e may be offset, shifted, or disposed on panels of other panel zones 50 and disposed at various distances from the base 14 (or the surface on which the base 14 is disposed). Further, fewer than four or more than four second handles 70b, 70c, 70d, 70e may be connected to the luggage bag 10. The first handle 70a and the second handles 70b, 70c, 70d, 70e may be any suitable handles for use with the luggage carrier. In the illustrated embodiment, the handles 70a, 70b, 70c, 70d, 70e are formed of a durable fabric and include a handle wrap. In other embodiments, the handles 70a, 70b, 70c, 70d, 70e may be formed of any suitable material.

[0084] Referring to FIGS. 4A, 5, and 6, the luggage bag 10 includes a rotatable handle 74 provided on a panel of the back 26 or the upper back panel 78 within the upper panel zone 50e. In the illustrated embodiment, the rotatable handle 74 projects away from the back 26 and is disposed adjacent to or toward the edge 54 (see FIG. 8) of the panel 78. In other embodiments, the handle 74 may be disposed at any desired position along the panel 78. The rotatable handle 74 is shown as being reinforced with a rubber handle wrap, but can be any other suitable handle for use with the luggage bag 10. In yet other embodiments, and as illustrated in FIG. 4B, the rotatable handle 74 may alternatively be disposed on the arcuate surface 66. Alternatively, the luggage bag 10 may include two rotatable handles 74, one positioned on the panel 78 (e.g., the position illustrated in FIG. 4A) and the other positioned on the arcuate surface 66 (e.g., the position illustrated in FIG. 4B).

[0085] Next, referring to FIGS. 5 and 6, the luggage bag 10 includes a bumper in the form of a rail 82 that is adjacent to, but separate from, the base 14 on a panel within the second panel zone 50b or on the bottom back panel 86. The rail 82 extends upwardly away from the base 14 and provides protection against damage to the luggage when the luggage bag 10 is pulled on a curb or other uneven surface. In the illustrated embodiment, the rail 82 is disposed on a single panel 86 and does not extend to adjacent panels or the base 14, thereby facilitating the foldability of the luggage bag 10 (described in further detail below). In an example of one or more embodiments, the rail 82 is approximately 2 cm to 5 cm wide and approximately 20 cm to 30 cm long. In other embodiments, the rail 82 may be any length or width suitable for providing protection against damage to the luggage bag 10 while facilitating the foldability of the luggage bag 10. In the illustrated embodiment, the luggage bag 10 includes a total of three rails 82 where the outermost first and second rails 82 are vertically aligned with the wheels 136a, 136b, respectively. The third intermediate rail 82 is approximately equidistant from the outermost rails 82. In other embodiments, any suitable number of rails 82, such as two rails 82 or four or more rails 82, may be implemented. In yet other embodiments, additional bumpers or rails 82 may be disposed on the first or bottom panel zone 50a or on other panels including the base 14.

[0086] Figures 6A through 6D illustrate an alternative embodiment of the luggage bag 10 having a bumper or bumper assembly 180 extending from the base 14 along a portion of the cover 18. The bumper 180 includes a rail 182 that removably engages a corresponding rail extension 186 protruding from the base 14. The combination of the rail 182 and the rail extension 186 provides a bumper that extends continuously or directionally from the base 14 along a portion of the cover 18, providing protection against damage to the luggage when the luggage bag 10 is dragged on a curb or other uneven surface, while facilitating the foldability of the luggage bag 10 by disengaging the rail 182 from the rail extension 186. In the illustrated embodiment, a plurality of rails 182 and a plurality of corresponding rail extensions 186 are depicted as three rails 182 and three rail extensions 186, but in other embodiments, the plurality of rails 182 may comprise any number of rails 182 (e.g., two to six or more), and the plurality of rail extensions 186 may comprise any corresponding number of rail extensions 186 (e.g., two to six or more).

[0087] Referring to FIGS. 6A through 6B, rail 182 is shown as a plurality of rails 182a, 182b, 182c disposed on a panel within the second panel zone 50b or on the bottom back panel 86. Each of the rails 182a, 182b, 182c is coupled to the panel 86 by one or more attachment members shown as a plurality of rivets passing through each of the rails 182a, 182b, 182c. In other embodiments, the rails 182a, 182b, 182c may be attached to the panel 86 by any suitable attachment member. Each of the rails 182a, 182b, 182c defines a channel 190 (best shown in FIG. 6C). The channel 190 may be further defined by an elongate portion 194 (shown in FIGS. 6B and 6D) of the rails 182a, 182b, 182c that is integrally formed with the rails 182a, 182b, 182c. The rails 182a, 182b, 182c extend from the panel 86 of the second panel zone 50b toward the base 14 and enter the first panel zone 50a across the fold 42 between the first panel zone 50a and the second panel zone 50b. More specifically, the elongate portion 194 of each of the rails 182a, 182b, 182c enters the first panel zone 50a across the fold 42 between the first panel zone 50a and the second panel zone 50b. The width of each rail 182 is about 1.9 inches, although in other embodiments it may be anywhere from 1.5 inches to 3.0 inches or more.

[0088] Referring to FIGS. 6A through 6D, rail extensions 186 are shown as a plurality of rail extensions 186a, 186b, 186c disposed on the base 14 and projecting in a direction away from the base 14. In the illustrated embodiment, the rail extensions 186a, 186b, 186c are generally in line with and project toward the corresponding rails 182a, 182b, 182c, respectively. The outermost rail extensions 186a, 186c are further generally in line with the respective wheels 136a, b of the base 14, while the intermediate rail extension 186b is between the outermost rail extensions 186a, 186c and may be centered between the outermost rail extensions 186a, 186c.

[0089] Each rail extension portion 186a, 186b, 186c includes protrusions 198a, 198b, 198c (shown in FIGS. 6C to 6D). The width of each protrusion 198 is about 1.5 inches, but in other embodiments, it may be anywhere from 1.2 inches to 2.0 inches or more, and more specifically, any width complementary to the associated rail 182 to facilitate engagement between the rail 182 and the protrusion 198 may be used. Each rail extension portion 186 extends about 1.8 inches from the base 14, and the protrusion 198 is about 0.6 inches (or 33% of the length of the rail extension portion 186). In other embodiments, the length of the rail extension portion 186 may be any suitable length, and the corresponding length of the protrusion 198 may be any suitable length or any proportion of the rail extension portion 186.

[0090] Each of the rails 182a, 182b, 182c removably engages a corresponding rail extension 186a, 186b, 186c. More specifically, each protrusion 198a, 198b, 198c is removably received by the elongate portion 194 of the channel 190 of the corresponding rail 182a, 182b, 182c to form a bumper 180 that extends continuously from the base 14 along a portion of the cover 18 when the luggage bag 10 is in the upright position illustrated in FIGS. 6A-6B (or the closed configuration as shown in FIG. 1). In the illustrated embodiment, the rails 182a, 182b, 182c disclose a removable engagement in the form of receiving a portion of the corresponding rail extensions 186a, 186b, 186c, but in other embodiments, any suitable removable engagement between the rail 182 and the rail extension 186 can be used. For example, the rail extension 186 may alternatively define respective channels sized to receive a portion of the corresponding rail 182. As another example, each rail 182 may be removably coupled to the corresponding rail extension 186 by a connecting member (e.g., snap button, interference fit, or other suitable fastener). In yet another embodiment, a combination of the removable engagement as shown in FIGS. 6A-6D and the use of one or more connecting members may be employed.

[0091] To facilitate the foldability of the luggage bag 10, each of the rails 182a, 182b, 182c disengages from the corresponding rail extensions 186a, 186b, 186c when the luggage bag 10 is in the stored position (or folded configuration) as illustrated in FIGS. 6C to 6D. To disengage each rail 182a, 182b, 182c from the corresponding rail extension 186a, 186b, 186c, the user folds the panel 86 having the attached rails 182a, 182b, 182c along the fold line 42. The rails 182a, 182b, 182c disengage from the corresponding rail extensions 186a, 186b, 186c as the rails 182a, 182b, 182c move away from the associated protrusions 198a, 198b, 198c during folding of the cover 18. In other embodiments, the rails 182a, 182b, 182c may be slid, pivoted, lifted, or otherwise disengaged from the associated rail extensions 186a, 186b, 186c by any suitable method for separating the rails 182a, 182b, 182c from the rail extensions 186a, 186b, 186c.

[0092] Referring back to FIG. 1, in some embodiments, the luggage bag 10 includes a storage pocket 90 on the front portion 22, more specifically, on a panel within a second panel zone 50b adjacent to but separate from the base 14 or on a bottom front panel 94. Referring to FIG. 27A, in some embodiments, the storage pocket 90 is disposed on the front portion 322 above a sub-panel 347 as will be described in more detail below. The storage pocket 90 includes a zipper, a zipper fastener, or any other suitable fastener that allows access to the interior of the storage pocket 90. In other embodiments, the storage pocket 90 can be disposed on a different panel on the front portion 22, the back portion 26, the first side portion 30, or the second side portion 34. Additionally, two or more storage pockets 90 can be disposed on the luggage bag 10. To facilitate the foldability of the luggage bag 10, the storage pocket 90 is disposed on a single panel and does not extend onto an adjacent panel or the base 14.

[0093] Next, referring to FIG. 8, in some embodiments, the back portion 26 is integrally formed with the first side portion 30 and the second side portion 34. For example, the back portion 26, the first side portion 30, and the second side portion 34 can be sewn, otherwise connected, or formed as an integral part of the cover 18. In some embodiments, a connecting member 98 in the form of a zipper fastener or a zipper (see also FIGS. 4A to 4B) separates the front portion 22 from the first side portion 30, the second side portion 34, and the back portion 26. In such embodiments, a first portion of the connecting member 98 defines a part of the outer periphery of the front portion 22, a second portion of the connecting member 98 defines a part of the outer periphery of the first side portion 30 and the second side portion 34, and extends along the arcuate edges 58a, 58b to the edge 54 of the back portion 26. Thus, the connecting member 98 removably connects the front portion 22 to the back portion 26, the first side portion 30, and the second side portion 34. In some embodiments, the connecting member 98 further separates the first side portion 30 and the second side portion 34 from the base 14. In such embodiments, the connecting member 98 thus removably connects the front portion 22 to the back portion 26, the first side portion 30, and the second side portion 34, and further removably connects the first side portion 330 and the second side portion 334 from the base 314.

[0094] It should be understood that the connecting member 98 can be any suitable device or assembly for connecting the front portion 22 to the back portion 26, the first side portion 30, and the second side portion 34, including but not limited to a hook-and-loop fastener, a zipper fastener, or a fly fastener. Further, although the connecting member 98 is illustrated in FIGS. 4A to 4B as having two opposing sliders 100a, 100b (such as a bifurcated fastener or a double-separating zipper fastener), in other embodiments, the connecting member 98 may include one slider, or three or more sliders.

[0095] When the front portion 22 is connected to or engaged with the back portion 26, the first side portion 30, and the second side portion 34 (as shown in FIG. 1), the respective portions 22, 26, 30, 34 define an internal chamber 102 for receiving articles for transfer. The front portion 22 may be selectively or partially detached or disengaged from the back portion 26, the first side portion 30, and the second side portion 34 so that a user can access the internal chamber 102 to various degrees. In FIG. 8, the luggage bag 10 is shown in an upright position, and only a portion of the front portion 22 is connected or engaged to the first side portion 30 and the second side portion 34 by one or more connecting members 98 (hereinafter referred to as connecting members 98), thereby partially exposing the internal chamber 102. By partially exposing the internal chamber 102, the user can place articles in the internal chamber 102 while the luggage bag 10 is in the upright position (or otherwise self-standing).

[0096] As shown in FIG. 8, the luggage bag 10 is provided in a partial access position or a first upright access position. The front portion 22 is shown in a folded state on a fold line 42 provided between panels of the second panel zone 50b and the third panel zone 50c. It is to be understood that the front portion 22 may be selectively or partially detached from the back portion 26, the first side portion 30, and the second side portion 34 such that any desired number of panel zones 50 are folded or folded up at a desired fold line 42 of the front portion 22, thereby enabling various amounts of access to the internal chamber 102.

[0097] Next, referring to FIG. 9, in some embodiments, the components of the luggage bag 10 are also folded or bent to form a butterfly opening, i.e., a second opening access position, to provide greater access to the internal chamber 102. In some embodiments, with the luggage bag 10 placed with the back 26 on a floor or other support surface, the connecting member 98 may be opened such that the front portion 22 is no longer connected to the back 26, the first side portion 30, and the second side portion 34, but remains connected to the base 14 and the internal chamber 102 is exposed. In other embodiments, the connecting member 98 may be opened such that the front portion 22 is no longer connected to the back 26, the first side portion 30, and the second side portion 34, and the first side portion and the second side portion are no longer connected to the base 14.

[0098] In some embodiments, the first side portion 30 and the second side portion 34 remain attached to the base 14. In these embodiments, the first side portion 30 and the second side portion 34 can then be freely pivoted or folded away from each other along their respective fold lines 42 (or seams) between the side portions 30, 34 and the back 26. When the first side portion 30 and the second side portion 34 are folded away from each other, the side portions 30, 34 form an oblique angle with respect to the back 26. The panels of the side portions 30, 34 of the second panel zone 50b are also folded about the angled fold line 42a.

[0099] In some embodiments, the first side portion 330 and the second side portion 334 are detached from the base 14 as shown in FIG. 29. In these embodiments, since the first side portion 330 and the second side portion 334 are folded away from each other, each portion 330, 334 can spread out flat with the back 326. When one or more articles are placed in the internal chamber 102, the side portions 30, 34 pivot or fold towards each other, the connecting member 98 is reconnected (or closed), the front portion 22 is fixed to the back 26, the first side portion 30, and the second side portion 34, and optionally the side portions 30, 34 are fixed to the base 14, thereby closing the internal chamber 102.

[0100] This butterfly opening not only pivots or folds such that the sides 30, 34 move apart from each other, but also, when the arcuate surface 66 is removed, there is no lip or other edge structure that would prevent or otherwise impede the insertion of an article into the internal chamber 102, so that the insertion of large or bulky articles into the internal chamber 102 is not hindered. In other words, when the travel bag is closed or opened in the manner shown in FIG. 8, the arcuate surface 66 overlaps a portion of the base 14 so as to surround the internal chamber 102. By opening the arcuate surface 66 away from the sides 30, 34 and the back 26 and then pivoting or folding the sides 30, 34 away from each other along the crease 42, the back 26, the first side 30, and the second side 34 thereby define a butterfly opening that provides immediate access to the internal chamber 102 without being obstructed by a portion of the cover 18. In other embodiments, the front portion 22 may be detachable from the base 14 or removable in some other way.

[0101] Referring to FIGS. 10 through 15, the base 14 is shown in more detail. The base 14 includes a bottom outer surface 110 opposite the inner surface 114. The inner surface 114 is defined or surrounded by a front wall 122 opposite the back wall 126 and a first side wall 130 opposite the second side wall 134. The front wall 122 is located on the same side as the front portion 22 of the luggage bag 10, while the back wall 126 is provided on the same side as the back portion 26 of the luggage bag 10. As shown in FIGS. 14 and 15, the first side wall 130 and the second side wall 134 increase in height at a wall distance away from the bottom surface 110 from the front wall 122 toward the back wall 126. In other embodiments, the first side wall 130 and the second side wall 134 may have a uniform height from the front wall 122 to the back wall 126. The inner surface 114 preferably defines a planar or substantially flat receiving surface that is substantially free of protrusions or other structural obstructions that could interfere with the receipt of an article onto the inner surface 114 of the base 14.

[0102] Base 14 includes a pair of wheels or skate wheels 136a, 136b provided on the side of the back wall 126. The skate wheels 136a, 136b do not pivot with respect to the base 14, and extend beyond the plane defined by the back wall 126 such that a portion of each of the wheels 136a, 136b extends outside the base contact area defined by the bottom surface 110 and the walls 122, 126, 130, 134. The wheels 136a, 136b preferably include a common rotation axis 138 offset from the plane defined by the bottom surface 110 and the back wall 126, and are configured to act as a pivot point for the luggage bag 10 to pivot from the upright position (see FIGS. 1 and 8) to the inclined position (see FIG. 19). The bottom surface 110 also preferably includes a curvature 139 (shown in FIGS. 10 and 13) between the wheels 136a, 136b defined by a radius in the range of 50 mm to 70 mm, more preferably about 60 mm. The radius of the curvature 139 provides a ground clearance zone between the wheels 136a, 136b and the bottom surface 110.

[0103] Base 14 further includes a pair of caster wheels 142a, 142b that pivot with respect to the base 14. Each of the caster wheels 142a, 142b preferably pivots 360 degrees around the pivot axis with respect to the base 14, and enables the luggage bag 10 to rotate in a controlled manner when in the upright position.

[0104] As shown in FIG. 10, the wheels 136a, 136b are preferably spaced apart by a first distance D1 of about 330 mm between the respective rotation points of the wheels 136a, 136b, while the caster wheels 142a, 142b are preferably spaced apart by a second distance D2 of about 300 mm between the respective pivot axes of the wheels 142a, 142b. In other embodiments, the first distance D1 and the second distance D2 can be any suitable or desired distance, and the first distance D1 is generally greater than the second distance D2. The wheels 136, 142 are arranged in the same plane, i.e., the wheels 136, 142 are arranged to contact the floor or other surface in the same horizontal plane. When the luggage bag 10 is in the upright position, both the non-rotating wheels 136a, 136b and the swivel wheels 142a, 142b remain in contact with the floor or other surface on which the luggage bag 10 is placed. This contact by all the wheels 136, 142 on the base 14 reduces the risk of unintentional movement of the luggage carrier while allowing the target rolling movement of the luggage bag 10 to continue. While the swivel wheels 142 allow for the directional movement of the luggage bag 10, the non-rotating wheels 136 function as stops that help prevent unintentional movement of the luggage carrier, for example, when a person or object pushes (or applies force to) one of the sides 30, 34.

[0105] The luggage bag 10 is foldable to reduce the storage footprint when not in use. The panels of the cover 18 are folded along the folds 42, 42a such that the panels are folded towards the base 14 and can be at least partially received by the base 14. As previously mentioned, the folds 42 are provided between adjacent or continuous panels at each of the front portion 22, the back portion 26, the first side portion 30, and the second side portion 34. Additionally, the folds 42 are provided between adjacent panels in any panel zone 50, such as between the panels of each adjacent or continuous section 26, 30, 34. In some embodiments, the angled folds 42a that are generally diagonal with respect to the base 14 also serve to facilitate folding the luggage bag 10 towards the base 14.

[0106] In some embodiments where the side portions 30, 34 remain attached to the base 14, to fold the luggage bag 10, the connecting member 98 is opened such that the front portion 22 is no longer fixed to the back portion 26, the first side portion 30, and the second side portion 34. Referring to FIGS. 16 and 17, in these embodiments, the front portion 22 is folded or bent along the fold line 42 between the panels and then received within the base 14. The side portions 30, 34 are also folded or bent along the angled fold line 42a towards the base 14. Subsequently, the panel between the base 14 and the fold line 42a is received within the base 14, followed by the panel on the opposite side of the fold line 42a. With the side portions 30, 34 positioned inwardly (or towards each other) to contact the back portion 26 when in use, the rail 182 disengages from the rail extension 186 and the remainder of the cover 18 is folded along the fold line 42 and partially received within the base 14 (see FIG. 17). In other embodiments, the cover 18 may be partially, substantially, or entirely received within the base 14.

[0107] In other embodiments, such as the luggage bag 300, as will be described in more detail below, the side portions 330, 334 are detached from the base 14. In such embodiments, to fold the luggage bag 300, the connecting member 98 is opened such that the front portion 322 is no longer fixed to the back portion 326, the first side portion 330, and the second side portion 334, and further such that the side portions 330, 334 are no longer fixed to the base. Referring to FIGS. 31A through 31C, in these embodiments, the front portion 322 is folded along the sub-panel 342b and further along the fold line 342 between the panels 346 and then received within the base 314. The side portions 330, 334 are folded inwardly towards the back portion 326 and then entirely received by the base 314. To further secure the cover 318 to the base 314, as shown in FIG. 30, the luggage bag 300 includes a clip 371 attached to the base 314 that is received within a loop attached to the back portion 326.

[0108] In some embodiments, in this folded storage position, the luggage bag 10 itself may be received in a storage bag 106 (see FIGS. 18A - 18B) for storage until later use. The cover 18 stays in the folded storage position due to the illustrated arrangement of the panels and folds, but the luggage bag 10 may include additional devices or assemblies that assist in holding the luggage bag 10 in the folded storage position for orderly storage. In some embodiments, the luggage bag 10 may include a simple strap or other device for maintaining the cover 18 in the folded position and avoiding the unintentional opening of the cover 18 from the folded position (e.g., due to an unintended drop of the folded and stored luggage bag 10). Such a simple strap may include a single strap or a cord such as a bungee that extends around a portion of the base 14 and the cover 18 and assists in maintaining the cover in the folded folded position.

[0109] FIG. 26 shows another embodiment of a storage bag 160 for receiving the luggage bag 10 when the luggage bag 10 is in a folded or stored position. The storage bag 160 includes a front panel 161, a back panel 162, a first side panel 163, a second side panel 164, a bottom panel 165, and two handles 166. The front panel 161, back panel 162, first side panel 163, second side panel 164, and bottom panel 165 each have a rectangular or substantially rectangular shape. These panels are integrally formed into a box - like shape. The front 161, back 162, first side 163, and second side panels 164 are aligned perpendicular to the bottom panel 165. The first panel 163 and the second side panel 164 are aligned perpendicular to the front panel 161 and the back panel 162. The upper portion of the storage bag 160 has an outer perimeter formed by the edges of the front panel 161, back panel 162, first side panel 163, and second side panel 164.

[0110] The storage bag 160 has a height measured orthogonally to the bottom panel from the bottom panel to the upper outer periphery of the storage bag 160. The height can be in the range of 30 to 60 cm. In some embodiments, the height is in the range of 30 cm to 40 cm, 35 cm to 45 cm, 40 cm to 50 cm, 45 cm to 55 cm, or 50 cm to 60 cm. In some embodiments, the height can be 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, 35 cm, 36 cm, 37 cm, 38 cm, 39 cm, 40 cm, 41 cm, 42 cm, 43 cm, 44 cm, 45 cm, 46 cm, 47 cm, 48 cm, 49 cm, 50 cm, 51 cm, 52 cm, 53 cm, 54 cm, 55 cm, 56 cm, 57 cm, 58 cm, 59 cm, or 60 cm. The storage bag 160 has a width measured parallel to the intersection between the bottom panel 165 and the front panel 161. The width can be in the range of 35 cm to 55 cm. In some embodiments, the width is in the range of 35 to 45 cm, 40 to 50 cm, or 45 to 55 cm. In some embodiments, the width can be 35 cm, 36 cm, 37 cm, 38 cm, 39 cm, 40 cm, 41 cm, 42 cm, 43 cm, 44 cm, 45 cm, 46 cm, 47 cm, 48 cm, 49 cm, 50 cm, 51 cm, 52 cm, 53 cm, 54 cm, or 55 cm. The storage bag 160 has a depth measured parallel to the intersection between the bottom panel 165 and the first side panel 163. The depth is in the range of 30 to 50 cm. In some embodiments, the depth is in the range of 30 to 40 cm, 35 to 45 cm, or 40 to 50 cm. In some embodiments, the height can be 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, 35 cm, 36 cm, 37 cm, 38 cm, 39 cm, 40 cm, 41 cm, 42 cm, 43 cm, 44 cm, 45 cm, 46 cm, 47 cm, 48 cm, 49 cm, or 50 cm.

[0111] The storage bag 160 can further include a handle 166. In some embodiments, a first handle is connected to the first side panel 163, and a second handle is connected to the second side panel 164. Further, in some embodiments, the upper outer periphery of the storage bag includes a channel for receiving and holding a drawstring. In these embodiments, the drawstring extends through an opening of the channel adjacent to the front panel 161.

[0112] Each panel 161, 162, 163, 164, and 165 of the storage bag 160 can be formed of a polyethylene board material [(C2H2) n H2], a foam material, a cloth material, or a combination thereof. The polyethylene board material can be any industry standard grade including, but not limited to, ultra-high molecular weight polyethylene (UHMWPE), ultra-low molecular weight polyethylene (ULMWPE), high molecular weight polyethylene (HMWPE), high density polyethylene (HDPE), high density cross-linked polyethylene (HDXLPE), cross-linked polyethylene (PEX), medium density polyethylene (MDPE), linear low density polyethylene (LLDPE), low density polyethylene (LDPE), very low density polyethylene (VLDPE), and chlorinated polyethylene (CPE). In other embodiments, the panels 161, 162, 163, 164, and 165 can be formed of polyurethane, acrylonitrile butadiene styrene, combinations thereof, or any other suitable material. The configuration of the storage bag 160 provides sufficient flexibility such that the drawstring mechanism can partially fold the storage bag 160 and fit it into the folded luggage bag 10. However, the panels 161, 162, 163, 164, and 165 of the storage bag 106 also provide a level of stiffness that allows the luggage bag to be stored in a box-shaped container.

[0113] Next, referring to FIG. 19, in many embodiments, the luggage bag 10 reduces the user's burden when in an inclined or pivotal position for pivoting on the wheels 136. To reach the illustrated inclined position, the user pivots the luggage bag 10 about the axis of rotation 138 of the wheels 136, for example using the rotatable handle 74. While pivoting, the end of the front wall 122 of the base 14 is lifted away from the ground or surface 146. Further, all the swivel wheels 142 are lifted away from contact with the surface 146. Next, when the user pulls the handle 74, the luggage bag 10 rolls on the wheels 136. Placing the handle 74 on the back 26 advantageously offsets or moves the handle 74 away from the wheels 136 in the pulling direction, reducing the burden on the user's wrist, hand, and arm when pulling (or applying a pulling force) on the luggage bag 10 and overcoming the load force L f of the force A applied by the user f to overcome. Additionally, when the user pulls the luggage bag 10 in the inclined position, a portion of the luggage bag 10 rests on the user's hand, wrist, and / or arm, reducing the application of the weight of the luggage on the user's hand, wrist, and arm.

[0114] Referring now to FIGS. 24 and 25, in some embodiments of the luggage bag 10, the internal chamber 102 further includes an internal cover 150. The internal cover 150 can serve to further add protection and padding around the golf club head stored within the luggage bag 10. The internal cover 150 is shaped to fit within the upper portion of the internal chamber 102 of the luggage bag 10. The internal cover 150 includes a front panel 151, a first side panel 153, a second side panel 154, and a back panel 152. The front panel 151 is curved so as to also form the top of the internal cover 150. The internal cover 150 further includes an opening that generally faces towards the bottom of the luggage bag 10. The internal cover 150 is attached to the luggage bag 10 only along one seam of the internal cover. The attached seam 155 is adjacent to the top of the internal cover 150 and is between the front panel and the back panel. The back panel 152 of the internal cover 150 can have a height between 15 cm and 30 cm as measured in the vertical direction. For example, the height of the back panel of the internal cover can be 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. In the illustrated embodiment, the height of the back panel 152 is approximately 22 cm. The first panel 153 and the second side panel 154 can each have a depth that is measured parallel to the ground surface and that is substantially orthogonal to the back panel 152. The depth of the first side panel is equal to the depth of the second side panel. The depth of the side panels 153, 154 can range from 10 cm to 25 cm. For example, the depth of the side panels 153, 154 can be 10 cm, 11 cm, 12 cm, 13 cm, 14 cm, 15 cm, 16 cm, 17 cm, 18 cm, 19 cm, 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, or 25 cm. In the illustrated embodiment, the depth of the side panels 153, 154 is approximately 16 cm. The front panel 151 and the back panel 152 can each have a width that is measured parallel to the ground surface and that is substantially orthogonal to the side panels 153, 154. In most embodiments, the widths of the front panel and the back panel are the same.The widths of the front panel and the back panel can be between 15 cm and 30 cm. For example, the widths of the front panel and the back panel can be 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. In the illustrated embodiment, the widths of the front panel and the back panel are approximately 22 cm.

[0115] To prevent rattling and displacement of the golf club head, the opening of the inner cover 150 constitutes a peripheral drawstring mechanism 156. The drawstring mechanism 156 can include a string, cord, rope, cord lock, hem, casing, loop, or other drawstring mechanism elements known in the art. The peripheral drawstring mechanism 156 secures the inner cover 150 around the golf club head. In some embodiments, the inner cover 150 comprises a cloth, foam, mesh, or other suitable padding material. In many embodiments, the inner cover 150 can have a thickness in the range between 0.05 cm and 2.0 cm, or between 0.5 cm and 1.5 cm. For example, the inner cover 150 can comprise an open cell foam with a thickness of 1 cm. In some embodiments, the stitches are sewn across a portion of the panels 151, 152, 153, 154.

[0116] I. First Exemplary Embodiment Figures 20 to 23 show a first exemplary embodiment of the rotatable foldable luggage carrier described in this specification. The exemplary luggage bag 200 is similar to the luggage bag 10. In this embodiment, the first panel zone 250a, the second panel zone 250b, and the third panel zone 250c each have a shape that is relatively similar to the first panel zone 50a, the second panel zone 50b, and the third panel zone 50c of the luggage bag 10, respectively. However, the fourth panel zone 250d and the fifth panel zone 250e of the luggage bag 200 have shapes that are slightly different from the fourth panel zone 50d and the fifth panel zone 50e of the luggage bag 10. From the front or rear views illustrated in FIGS. 20 and 21, both the fourth panel zone 250d and the fifth panel zone 250e have a trapezoidal shape that tapers more sharply than the first embodiment described initially. In other words, the fourth width W4 of the luggage bag 200 is smaller than the fourth width W4 of the luggage bag 10.

[0117] In the illustrated embodiment, the height of the first panel zone 250a is about 6 cm, the height of the second panel zone 250b is 31.5 cm, the height of the third panel zone 250c is about 31.5 cm, the height of the fourth panel zone 250d is about 31.5 cm, and the height of the fifth panel zone 250e is about 21.5 cm when measured along the back 226. Further, as shown in FIGS. 22 and 23, when viewed from the side, the fourth panel zone 250d can have a side edge with an angular change approximately halfway up the height of the panel. The top of that side edge leads to a fifth panel zone having an edge with an approximately straight angular edge instead of an arcuate edge. The edge of the fifth panel zone also has an angular change to provide a small flat top that engages with the handle.

[0118] II. Second Exemplary Embodiment Figures 27A through 33 illustrate another exemplary embodiment of the rotatable foldable luggage bag described herein. Luggage bag 300 includes a cover 318 that lies flat in an open configuration to provide full access to internal chamber 304. Luggage bag 300 can provide maximum access to internal chamber 304 without sacrificing its ability to fully fold. Luggage bag 300 is similar to luggage bag 10 and includes a front flap 322 that is completely detachable from back 326, first side 330, and second side 334. However, first side 330 and second side 334 are configured to be completely detachable from base 314 to form a flat surface for the user to insert items into luggage bag 300. Thus, luggage bag 300 provides maximum access to internal chamber 304. The detachability of sides 330, 334 provides additional benefits to luggage bag 300, such as improved foldability and storability, as will be described in more detail below.

[0119] Referring to FIG. 27A, front flap 322 is integrally formed with base 314 and is selectively removable from back 326, first side 330, and second side 334 to provide access to internal chamber 304. Further, back 326 is integrally formed with base 314, first side 330, and second side 334, similar to luggage bag 10. Luggage bag 300 differs from luggage bag 10 in that first side 330 and second side 334 are selectively removable from base 314. When lying flat in an open configuration, back 326, first side 330, and second side 334 form a flat surface that provides full access to internal chamber 304, as shown in FIG. 29. In many conventional designs, the back and sides are not completely detachable from the base and thus do not provide maximum access to the internal chamber.

[0120] The luggage bag 300 includes a plurality of panels 346 arranged in a plurality of panel zones 350. The structure and configuration of the panels 346 of the luggage bag 300 are similar to those of the panel 46 of the luggage bag 10. Each of the panels 346 of the luggage bag 300 defines a front height near the front portion 322 and a side height near the first side portion 330 and the second side portion 334. The height of the panels 346 within each zone 350 can be the same or can be varied. The main difference in the exemplary luggage bag 300 is the arrangement of the panels 346 within the panel zones 350. For example, in some panel zones 350, the panels 346 are stacked such that the panels 346 within the front portion 322, the back portion 326, the first side portion 330, and the second side portion 334 are offset from each other, as illustrated in FIG. 27A. The offset of the panels enables the cover 318 to be completely folded onto the base 314.

[0121] Referring to FIGS. 28A and 28B, the panel 346a within the first panel zone 350a has a first front panel height H of approximately 11 cm 1F However, as described above, the first panel height H1 can vary depending on the size, shape, and / or orientation of the luggage bag 300. The panel 346a within the first panel zone 350a further has a first side panel height H that decreases from the front to the back such that the panel 346a is longer near the front flap 322 and shorter near the back portion 326 so as to conform to the inclined height of the base 314, as discussed in more detail below. 1S has. The first side panel height H 1S can be about 5.0 cm, 5.5 cm, 6.0 cm, 6.5 cm, 7.0 cm, 7.5 cm, 8.0 cm, 8.5 cm, 9.0 cm, 9.5 cm, 10.0 cm, 10.5 cm, 11.0 cm, 11.5 cm, 12 cm, 12.5 cm, 13.0 cm, 13.5 cm, 14.0 cm, 14.5 cm, or 15.0 cm. In some embodiments, the first side panel height H 1Scan be less than 6.5 cm, 6.4 cm, 6.3 cm, 6.2 cm, 6.1 cm, or 6.0 cm based on the size, shape, or orientation of the luggage bag 10. In other embodiments, the first side panel height H 1S can be greater than 6.5 cm, 6.6 cm, 6.7 cm, 6.8 cm, 6.9 cm, or 7.0 cm based on the size, shape, or orientation of the luggage bag 10. In some embodiments, the first side panel height H 1S is tapered between approximately 11 cm near the front flap 322 and approximately 2 cm near the back 326. The taper of the panel 346a from near the front flap 322 to near the back 326 forms triangular panels near the first side 330 and the second side 334.

[0122] As described above, the luggage bag 300 utilizes a folding mechanism different from that of the luggage bag 10. The main difference lies in the configuration of the panel 346b within the second panel zone 350b. Referring to FIG. 28A, the panel 346b (main front panel 346b) within the second panel zone 350b of the front flap 322 includes a sub-panel 347. The sub-panel 347 is located closer to the first panel zone 350a than the main front panel 346b. The sub-fold line 342b defines the boundary between the sub-panel 347 and the main front panel 346b. To fold the luggage bag 300, the front is first folded along the sub-fold line 342b such that the sub-panel 347 is first received into the base 314.

[0123] Referring to FIG. 28A, the main front panel 346b defines a second main panel height H of approximately 25 cm 2MF In some embodiments, the second main panel height H 2MF can be 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, 25 cm, 26 cm, 27 cm, 28 cm, 29 cm, 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, 35 cm, 36 cm, 37 cm, 38 cm, 39 cm, or 40 cm. In some embodiments, the second main panel height H 2MFcan be less than 30 cm, 29 cm, 28 cm, 27 cm, 26 cm, or 25 cm based on the size, shape, or orientation of the luggage bag 10. In other embodiments, the second main panel height H 2MF can be greater than 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, or 25 cm based on the size, shape, or orientation of the luggage bag 10. The sub-panel 347 has a sub-panel height H 2SF defining about 12 cm. In some embodiments, the sub-panel height H 2SF can be about 5.0 cm, about 5.5 cm, about 6.0 cm, about 6.5 cm, about 7.0 cm, about 7.5 cm, about 8.0 cm, about 8.5 cm, about 9.0 cm, about 9.5 cm, about 10.0 cm, about 10.5 cm, about 11.0 cm, about 11.5 cm, about 12 cm, about 12.5 cm, about 13.0 cm, about 13.5 cm, about 14.0 cm, about 14.5 cm, or about 15.0 cm. In some embodiments, the sub-panel height H 2SF can be less than 6.5 cm, 6.4 cm, 6.3 cm, 6.2 cm, 6.1 cm, or 6.0 cm based on the size, shape, or orientation of the luggage bag 10. In other embodiments, the sub-panel height H 2SF can be greater than 6.5 cm, 6.6 cm, 6.7 cm, 6.8 cm, 6.9 cm, or 7.0 cm based on the size, shape, or orientation of the luggage bag 10.

[0124] Referring again to FIG. 28A, the main front panel 346b and the sub-panel 347 within the second panel zone 350b define a combined second front panel height H 2F of about 40 cm. In some embodiments, the second front panel height H 2F can be less than 50 cm. In some embodiments, the second front panel height H 2Fcan be 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, 25 cm, 26 cm, 27 cm, 28 cm, 29 cm, 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, 35 cm, 36 cm, 37 cm, 38 cm, 39 cm, 40 cm, 41 cm, 42 cm, 43 cm, 44 cm, 45 cm, 46 cm, 47 cm, 48 cm, 49 cm, or 50 cm. In some embodiments, the second front panel height H 2F can be less than 30 cm, 29 cm, 28 cm, 27 cm, 26 cm, or 25 cm, based on the size, shape, or orientation of the luggage bag 10. In other embodiments, the second front panel height H 2F can be greater than 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, or 35 cm, based on the size, shape, or orientation of the luggage bag 10.

[0125] The sub-panel height H 2SF is approximately the same as the height of the base 314, thereby allowing the sub-panel 347 to be housed in the base 314 and remain stationary with respect to the front wall of the base, as shown in FIG. 31A. The sub-panel 347 raises the height of the main front panel 346b such that, as shown in FIG. 27A, the main front panel 346b is positioned at a location offset from the panel 346b near the first side 330 and the second side 334.

[0126] In addition to the sub-panel 347, the panels 346b within the first side portion 330 and the second side portion 334 are further different from those of the luggage bag 10. Specifically, the panel 346b does not include angled creases as in the previous embodiment (see FIG. 6). Instead, the panels 346b near the first side portion 330 and the second side portion 334 each comprise a single panel. The single panel can prevent buckling within the second panel zone 350b, thereby preventing wear within the panel 346b at the intersection between the base 314 and the cover 318. In previous designs, wear occurred in similar areas of the panel because the side panel was not completely removable from the base. In other embodiments, angled creases help facilitate the foldability of the cover. However, the luggage bag 300 utilizes a different folding mechanism, as will be described in more detail below.

[0127] Referring to FIG. 28B, the panel 346b within the second panel zone 350b has a second side panel height H that increases from the front towards the back such that the panel 346b is longer near the back 326 and shorter near the front flap 322. 2S further has. In some embodiments, the second side panel height H 2S can be less than 50 cm. In some embodiments, the second side panel height H 2S can be 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, 25 cm, 26 cm, 27 cm, 28 cm, 29 cm, 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, 35 cm, 36 cm, 37 cm, 38 cm, 39 cm, 40 cm, 41 cm, 42 cm, 43 cm, 44 cm, 45 cm, 46 cm, 47 cm, 48 cm, 49 cm, or 50 cm. In some embodiments, the second side panel height H 2S can be less than 30 cm, 29 cm, 28 cm, 27 cm, 26 cm, or 25 cm based on the size, shape, or orientation of the luggage bag 10. In other embodiments, the second side panel height H 2Scan be made greater than 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, or 35 cm based on the size, shape, or orientation of the luggage bag 10. In one exemplary embodiment, the second side panel height H 2S increases from about 30 cm near the front flap 322 to about 36.5 cm near the back 326.

[0128] The taper of the panel 346b within the second panel zone 350b follows the contour of the first panel zone 350a near the first side 330 and the second side 334. Referring to FIG. 27A, the increase in the height of the panel 346b of the second panel zone 350b forms a trapezoidal panel near the first side 330 and the second side 334.

[0129] As described above, the luggage bag 300 includes a first panel zone 350a and a second panel zone 350b that are different from the first panel zone 50a and the second panel zone 50b of the luggage bag 10. The luggage bag 300 further includes a third panel zone 350c, a fourth panel zone 350d, and a fifth panel zone 350e that have relatively similar shapes to the first panel zone 50a, the second panel zone 50b, and the third panel zone 50c of the luggage bag 10, respectively.

[0130] Referring to FIGS. 28A and 28B, the panel 346c within the third panel zone 350c has a third front panel height H of about 25 cm 3F In some embodiments, the third front panel height H 3F can be 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, 25 cm, 26 cm, 27 cm, 28 cm, 29 cm, 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, 35 cm, 36 cm, 37 cm, 38 cm, 39 cm, or 40 cm. In some embodiments, the third front panel height H 3F can be less than 30 cm, 29 cm, 28 cm, 27 cm, 26 cm, or 25 cm based on the size, shape, or orientation of the luggage bag 10. In other embodiments, the third front panel height H 3Fcan be made greater than 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, or 25 cm based on the size, shape, or orientation of the luggage bag 10. The panel 346c within the third panel zone 350c further has a third side panel height H of approximately 33.5 cm 3S In some embodiments, the third side panel height H 3S can be 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, 25 cm, 26 cm, 27 cm, 28 cm, 29 cm, 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, 35 cm, 36 cm, 37 cm, 38 cm, 39 cm, or 40 cm. In some embodiments, the third side panel height H 3S can be less than 40 cm, 39 cm, 38 cm, 37 cm, 36 cm, or 35 cm based on the size, shape, or orientation of the luggage bag 10. In other embodiments, the third side panel height H 3S can be made greater than 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, or 35 cm based on the size, shape, or orientation of the luggage bag 10. Similar to the panel 346b of the second panel zone 350b, the panel 346c near the front flap 322 is arranged offset from the panel 346c near the first side 330 and the second side 334, as shown in FIG. 27A. The heights H 3F 、H 3S remain substantially constant such that the panel 346c is rectangular.

[0131] Referring to FIGS. 28A and 28B, the panel 346d within the fourth panel zone 350d has a fourth front panel height H of approximately 25 cm 4F The panel 346d within the fourth panel zone 350d further has a fourth side panel height H of approximately 33.5 cm 4S Similar to the panel 346b of the second panel zone 350b, the panel 346d near the front flap 322 is arranged offset from the panel 346d near the first and second sides 330, 334, as shown in FIG. 27A. The heights H 4F 、H 4Sremains substantially constant such that panel 346d is rectangular.

[0132] Referring to FIGS. 28A and 28B, panel 346e within the fifth panel zone 350e has a fifth front panel height H of about 20 cm 5F and a fifth side panel height H. 5S In some embodiments, the fifth front panel height H 5F can be 10 cm, 11 cm, 12 cm, 13 cm, 14 cm, 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. In some embodiments, the fifth front panel height H 5F can be less than 30 cm, 29 cm, 28 cm, 27 cm, 26 cm, or 25 cm based on the size, shape, or orientation of the luggage bag 10. In other embodiments, the fifth front panel height H 5F can be greater than 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, or 25 cm based on the size, shape, or orientation of the luggage bag 10. Panel 346e within the fifth panel zone 350e is substantially similar to panel 46e within the fifth panel zone 50e of the luggage bag 10 with respect to the type, position, and shape of the panel.

[0133] Luggage bag 300 is similar to luggage bag 10, but has a different panel configuration and panel height. The panel 346 of luggage bag 300 defines a width, depth, and thickness similar to that of panel 46 of luggage bag 10. Luggage bag 300 further includes a plurality of handles 370a, 370b, 370c, 370d, 370e, 374 similar to the handle of luggage bag 10.

[0134] Referring to FIG. 27A, the luggage bag 300 further includes a storage pocket 390 located at the front portion 322. The storage pocket 390 is located above the sub-panel 347 on the main front panel 346b. To facilitate the foldability of the luggage bag 300, the storage pocket 390 stays within the main front panel 346b and does not extend to the adjacent panel. In other words, the storage pocket 390 does not cross the fold line 342 and thus does not interfere with the foldability of the luggage bag 300.

[0135] In some embodiments, the luggage bag 300 further includes one or more inner pockets formed near the inner chamber 304. Referring to FIGS. 32 and 33, the luggage bag 300 can include a first inner pocket 379 near the first side portion 330 and a second inner pocket 381 near the second side portion 334. The one or more inner pockets 379, 381 can be formed of mesh or can be zippered pockets. In some embodiments, the one or more inner pockets 379, 381 can extend over the fold line 342 such that the inner pockets 379, 381 extend into the plurality of panel zones 350 as shown in FIGS. 32 and 33. In other embodiments, the inner pockets 379, 381 do not extend into the plurality of panel zones 350 as illustrated in FIG. 29. The inner pockets 379, 381 can be accessed while the luggage bag 300 is in the open configuration.

[0136] FIG. 29 shows a luggage bag 300 in an open configuration capable of storing clubs. Similar to the luggage bag 10, the back 326 is integrally formed with the first side portion 330, the second side portion 334, and the base 314. However, in contrast to the luggage bag 10, the first side portion 330 and the second side portion 334 are not integrally formed with the base 314. Therefore, the first side portion 330 defines a first bottom edge 355, and the second side portion defines a second bottom edge 357. The first bottom edge 355 and the second bottom edge 357 each define a part of the outer periphery of the first side portion 330 and the second side portion 334, respectively. To open the luggage bag 300, a connecting member 398 (see also FIGS. 4A - 4B) separates the front portion 322 from the first side portion 330, the second side portion 334, and the back 326. The connecting member 398 further separates the first side portion 330 and the second side portion 334 from the base 314. A first portion of the connecting member 398 defines a part of the outer periphery of the front portion 322, and a second portion of the connecting member 398 defines a part of the outer periphery of the first side portion 330 and the second side portion 334 and extends along the first bottom edge 355 and the second bottom edge 357. The connecting member 398 thus removably connects the front portion 322 to the back 326, the first side portion 330, and the second side portion 334, and further removably connects the first side portion 330 and the second 334 to the base 314. Since the first bottom edge 355 and the second bottom edge 357 are not integrally formed with the base 314, it allows the first side portion 330 and the second side portion 334 to open away from the base 314. Similar to the luggage bag 10, the front portion 322 of the luggage bag 300 is selectively or partially disconnectable or disengagable from the back 326, the first side portion 330, and the second side portion 334, so that the user can access the inner chamber 304 to various extents.

[0137] The connection mechanism of the front flap 322 is similar to that of the luggage bag 10, but the luggage bag 300 includes an improved butterfly opening of the luggage bag 300. Referring again to FIG. 29, the first side portion 330 and the second side portion 334 are folded or bent to form a flat surface, i.e., a second opening access position, to provide greater access to the internal chamber 304. With the luggage bag 300 placed such that the back 326 is positioned on the floor or other support surface, the connecting member 398 is opened so that the front 322 is no longer connected to the back 326, the first side portion 330, and the second side portion 334, exposing the internal chamber 304. The connecting member can be further opened so that the first side portion and the second side portion are no longer connected to the base 314. The first side portion 330 and the second side portion 334 then pivot or fold freely with respect to each other along their respective fold lines 342 (or seams) between the side portions 330, 334 and the back 326.

[0138] In the open configuration, the first side portion 330 and the second side portion 334 lie flat and planar with the back 326. This flat mat-like opening allows for the insertion of large or bulky items into the internal chamber 304 without being hindered by a lip or other edge structure that would otherwise impede insertion into the internal chamber 304. Thus, the luggage bag 300 provides maximum allowable access to the internal chamber 304.

[0139] When one or more articles are placed into the interior chamber 304, the side portions 330, 334 are pivoted or folded towards each other, the connecting member 398 is reconnected (or closed), the first side portion 330 and the second side portion 334 are fixed to the base, and further the front portion 322 is fixed to the back portion 326, the first side portion 330, and the second side portion 334, thereby closing the interior chamber 304. In many prior art luggage bags, the cover is arranged with a single connecting member or zipper passing through the middle portion. In these embodiments, the user handles the golf bag through a single central opening of the luggage compartment and further has to handle the zipper around the golf bag to enclose the internal cavity. However, the luggage bag 300 enables the user to place the articles on a flat surface (the flattened back portion 326, the first side portion 330, and the second side portion 334) and easily reconnect the respective parts to enclose the interior chamber 304.

[0140] The base 314 of the luggage bag 300 is similar to the base 14 of the luggage bag 10. Specifically, the height of the base 314 increases from near the front portion 322 to near the back portion 326. However, the base 314 can be slightly higher near the front portion 322 to facilitate foldability, as will be described in more detail below. In some embodiments, the height of the base can be 10 cm, 11 cm, 12 cm, 13 cm, 14 cm, 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. In an exemplary embodiment, the height of the base 314 is 16.2 cm near the front portion 322.

[0141] The luggage bag 300 is foldable to reduce the storage footprint when not in use. The panel 346 of the cover 318 is folded along the fold lines 342, 342b, allowing the panel 346 to be folded towards the base 314 and received by the base 314. The fold lines 342 are provided between adjacent or continuous panels at each of the front 322, back 326, first side 330, and second side 334. Additionally, the fold lines 342 are provided between the panels of each adjacent or continuous section 326, 330, 334, such as between adjacent panels in any panel zone 350.

[0142] Figures 31A through 31C illustrate the foldability of the luggage bag 300. The foldability of the luggage bag 300 is slightly different from that of the luggage bag 10. First, the luggage bag 300 does not include angled fold lines within the second panel zone 350b to facilitate the folding of the first side 330 and the second side 334. Instead, the front 322 of the luggage bag 300 further includes a sub-fold line 342b that allows the sub-panel 347 to be folded inwardly towards the base 314.

[0143] To fold the luggage bag 300, the connecting member 398 is opened so that the front 322 is no longer fixed to the back 326, the first side 330, and the second side 334, and the sides 330, 334 are further opened so that they are no longer fixed to the base. Referring to FIG. 31A, the front 322 is first folded along the sub-fold line 342b such that the sub-panel 347 becomes the first panel received within the base 314. The front 322 is further folded along the fold line 342 between the panels 346 and then received within the base 314. The sides 330, 334 are folded inwardly towards the back 326 and received by the base 314. When in use, the rail 382 is disengaged from the rail extension 386, and the remainder of the cover 318 is folded along the fold line 342 and partially received by the base 314 (see FIGS. 31A through 31C).

[0144] The luggage bag 300 utilizes a self-storing function and does not require an additional storage bag to assist in holding the luggage bag 300 in a folded storage position for neat storage. Referring to FIG. 30, this self-storing function is facilitated by a clip 371 disposed on a base 314 that is received within a loop 375 disposed on the back 326. In the folded position, the clip 371 engages the loop 375 to compress the cover 318 within the base 314. The clip 371 is secured to the base via a first strap 373, which is attached to the base 314 near the front side of the luggage bag 300. The loop 375 is secured to the back 326 via a second strap 377 attached to the panel 346b near the back as shown in FIG. 27B. The first strap 373 and the second strap 377 can be sewn or otherwise attached to the luggage bag 300. As described above, in the folded position, the cover 318 is received within the base such that the panel 346b near the back 326 is exposed to the outside. Thus, in the folded position, it is proximate to the loop clip 372, whereby the user can easily hook the clip 371 within the loop 375 to compress the cover 318 within the base 314. When the luggage bag 300 is in the folded position, the luggage bag 300 is movable along the ground or a support surface via wheels. Accordingly, the user can easily store the luggage bag 300 in a low position using the handle 370a.

[0145] Manufacturing method The method of manufacturing the luggage bag 10 comprises the step of providing a base 14 and the step of coupling a first wheel 136a, a second wheel 136b, a third wheel 142a, and a fourth wheel 142b to the base 14. The method further comprises the step of attaching or fixing a back 26, a first side 30, and a second side 34 to the base 14. Further, the method comprises the step of attaching or fixing a front 22 to the base 14. The method also comprises the step of removably connecting the front 22 to the back 26, the first side 30, and the second side 34 by a connecting member 98. It should be understood that the disclosed manufacturing method is exemplary and the method may be completed in any suitable order or series of steps. Further, two or more manufacturing steps may be completed simultaneously.

[0146] The rotatable luggage bag 10 provides advantages over known luggage in the art. Among other things, when the luggage bag 10 is in an upright position, utilizing an improved wheel arrangement of non-rotating wheels 136 combined with swivel wheels 142 that all remain in contact with the floor or other surface allows for the intended rotational movement of the luggage bag 10 while reducing the risk of unintended movement of the luggage and reducing its overall weight. Further, the position of the handle 74 also reduces the user's burden when the luggage bag 10 is rolled in an inclined position. Further, the user can access the interior chamber 102 defined by the luggage bag 10 through the butterfly opening without being blocked, which further facilitates the insertion and removal of large and / or bulky items. Further, the panels defining the front 22, the back 26, the first side 30, and the second side 34 are folded along a plurality of creases 42 that separate adjacent panels. By folding, the respective parts 22, 26, 30, 34 cooperate to fold onto the base 14, reducing the storage footprint of the luggage bag 10 when not in use.

[0147] Embodiment This specification further describes a comparison of two luggage bags using different foldable mechanisms. The results compared the impact of the panel structure and the foldable mechanism on the overall foldability of the bag. As described above, these variables can determine how much the golf bag can be folded to facilitate storage.

[0148] The control golf bag had a total of 22 panels arranged in five panel zones, similar to the luggage bags illustrated in FIGS. 1 to 6. The panels of the control golf bag were arranged such that the sides were non-removably attached to the base. To open the control bag, the front was removed from the sides, and the sides pivoted away from each other or were folded. Since the sides were connected to the base, the control bag defined a butterfly opening similar to that shown in FIGS. 8 to 9. The control bag also included angled creases to facilitate folding of the bag. To fold the control bag, the front was removed from the sides, folded along the creases between each panel, and received within the base. Next, similar to the luggage bag illustrated in FIG. 17, the sides were folded towards the base along the angled creases. In the folded position, the control bag was 43.8 cm wide, 33.6 cm deep, and 30.5 cm high. In the upright position, the volume of the internal chamber of the control bag was 0.118 m 3 It was.

[0149] The exemplary golf bag included a total of 21 panels arranged in five panel zones, similar to the luggage carrier illustrated in FIGS. 27A through 28B. The panels of the exemplary bag were arranged such that the sides were removable from the base and the front included a sub-panel. To open the exemplary bag, the front was removed from the sides, which were folded away from each other. Since the sides were removable from the base, the exemplary bag defined a flat surface similar to that shown in FIG. 29. To fold the exemplary bag, the front was removed from the sides, the sub-panel was received within the base, and the remaining panels were folded and received within the base. Next, similar to the luggage bag illustrated in FIGS. 31A through 31C, the sides were folded inwardly toward the back and received within the base. The exemplary bag included clips that engaged loops to compress the cover within the base, similar to the luggage carrier illustrated in FIG. 30. In the folded position, the exemplary bag was 43.8 cm wide, 33.6 cm deep, and 21.6 cm high. In the upright position, the volume of the internal chamber of the control bag was 0.118 m 3 was.

[0150] In the comparison, the volume of the internal chamber in the upright position and the volume and height of each golf bag in the folded position were measured. The volume of the internal chamber was maximized for each golf bag such that any golf bag could be held within the internal chamber. The folded height and volume of the golf bag determine the ease of storage of the golf bag. The exemplary golf bag demonstrated ease of storage compared to the control bag, as described in further detail below.

Table 1

[0151] Referring to Table 1, it can be seen that the exemplary golf bag has improved foldability compared to the control bag. The bag has a similar internal chamber volume of 0.118 m 3 in the upright position, but the exemplary bag exhibited a smaller volume when folded. Specifically, the control bag was 0.0448 m 3has a folded volume, and the exemplary bag had a folded volume of 0.0317 m 3 (29.2% smaller). Further, the exemplary bag was 8.9 cm shorter than the control bag in the folded position. Due to the reduced height and volume of the exemplary luggage bag, the bag can be stored more easily than the control bag. The improved performance of the exemplary golf bag was due to the panel structure and folding mechanism.

[0152] As described above, the exemplary bag had sides that were completely removable from the base. And the sides could pivot completely inwards towards the back before being received within the base. The exemplary bag further included a sub-panel at the front to assist the front fitting within the base. Both the removable sides and the sub-panel optimized the storage capacity of the base, resulting in a smaller height and volume when folded. On the other hand, the control bag included sides that were non-removably attached to the base, and the sides were first folded along angled creases before being received within the base.
