Description

[Technical field]

[0001] The present invention relates generally to adjustable luggage cases configured to adjust size and / or height, and more particularly to roll-top luggage cases having soft sides and a rigid or semi-rigid base. [Background technology]

[0002] Existing luggage cases are generally hard-sided or soft-sided, or a mixture of the two. Hard-side cases provide high protection for the bag, but have limited or no ability to change the interior volume of the bag. As a result, hard-side bags take up a large amount of space even when not filled to capacity. Furthermore, hard-side bags can cause the contents to shift within the container when not filled to capacity. In contrast, soft-side bags can provide less protection, but are often difficult to move. For example, soft-side bags often must be carried. Some soft-side bags may include wheels, partial frames, or handle assemblies to facilitate movement of the soft-side bag, but even then, the contents can shift within the container when not filled to capacity.

[0040] The present application discloses a luggage case that includes soft sides and a base portion. The base portion can be rigid or semi-rigid. The luggage case is capable of transitioning between two or more configurations to selectively change the size or capacity of an interior volume defined by the soft sides and base portion. The two or more configurations can also selectively change the exterior size or height of the luggage case. Thus, a luggage case is disclosed that is selectively configurable to a variety of volumes.

[0041] The base portion is disposed at or defines a bottom of the luggage case. One or more wheel assemblies or support structures configured to engage the ground are attached to or extend from the bottom of the luggage case. The base portion also includes a rear base portion extending from the bottom. The rear base portion may be disposed at a rear of the luggage case. The base portion may be at least partially rigid or semi-rigid. The base portion may define a frame or support structure for the luggage case. The luggage case may also include a telescoping towing handle. The telescoping towing handle may include at least one down tube that may retract into or extend from the handle support structure of the base portion.

[0042] The flexible side portion is made of a flexible material. The flexible side portion extends from and is coupled to the base portion and can define a portion or all of both the front and back panels of the luggage case. The flexible side portion includes a roll-top portion. The roll-top portion is disposed opposite the base portion and defines an opening that is selectively closed or opened by rolling or unrolling the roll-top portion between a rolled configuration and an unrolled configuration, respectively. The roll-top portion also includes one or more engagement structures that can selectively secure the roll-top portion in a rolled configuration. Each roll configuration can change the interior volume capacity or exterior size of the luggage case. That is, rolling or unrolling the roll-top portion decreases (by rolling) or increases (by unrolling) the interior storage volume. The engagement structures can be coupled to each other or to receiving structures that are disposed along a portion of the luggage case to secure the roll-top portion in one or more roll configurations. One or more straps, and preferably at least two straps, are coupled to or defined by the flexible side portion. The straps are disposed in a spaced apart configuration on the rear side of the soft side portions relative to each other and to the rear panel of the luggage case.

[0043] The towing handles can selectively engage the soft side portions to provide structure or rigidity to the soft side portions. For example, the towing handles can be engaged with or received by straps. In one embodiment, the downtubes of the telescoping towing handles can be received within or pass through spaces defined between the respective straps and the rear panel of the luggage case to provide support to or help define the upper portion in the unrolled configuration. In some embodiments, two or more straps can each selectively engage the towing handles to help define multiple rolled configurations, each defining a different internal volume capacity. That is, the towing handles can be fully extended and pass through spaces defined between the respective straps and the rear side of the soft side portions to partially or fully extend the soft side portions.

[0044] In some embodiments, a U-shaped zipper can extend along or around the perimeter of the front panel of the luggage case. The base of the U-shape is located at or adjacent the bottom of the luggage case. The U-shaped zipper allows access to the interior volume of the luggage case regardless of whether the roll-top portion is in an unrolled or rolled configuration.

[0045] In some embodiments, the bottom of the luggage case may include a foldable wheel assembly. The foldable wheel assembly may allow the luggage case to rotate or be held between two or more configurations. For example, the wheel assembly may allow the luggage case to be folded into a more compact, smaller rolled configuration for transportation or storage.

[0046] In use, the flexible sides can transition between an unrolled configuration and a rolled configuration to selectively change the interior and exterior size of the luggage case. In some embodiments, the bottom can be foldable and arranged into a compact configuration for transportation, storage, or storage within a second luggage case. The various size configurations can accommodate luggage sizes for public transportation services and carriers, such as bus lines, airlines, train lines, etc. For example, for airlines, the luggage case can be in various size configurations to accommodate large duffels, checked bags, carry-on bags, totes or underseat bags, or pouches for storage within a second luggage case.

[0047] Referring to the figures, FIG. 1A illustrates a front perspective view of an exemplary luggage case 100. FIG. 1B illustrates a rear perspective view of the exemplary luggage case 100. The luggage case 100 may be referred to as a luggage item, a bag, a trolley, or the like. The luggage case 100 may be a rolling luggage case. The luggage case 100 includes a front side 104 and a rear side 106 opposite the front side 104, a left side 108 disposed between the front side 104 and the rear side 106, and an opposite right side 110. The luggage case 100 also includes a top side 112 and an opposite bottom side 114. The luggage case 100 may include a height dimension H, a width dimension W, and a depth dimension D.

[0048] Luggage case 100 includes soft side portions 130 and a base portion 120. The soft side portions 130 and the base portion 120 together define an interior volume 160 of luggage case 100 for transporting or storing items. The interior volume 160 is accessible from the top side 112 through the roll-top portion 132 or from the front side 104 through a closure assembly zipper 230, as shown in FIG. 2 or FIG. 3 and discussed in more detail below.

[0049] As can be seen from the figures, luggage case 100 can have one or more rolled configurations as a result of rolling or unrolling luggage case 100. For example, in FIG. 1A, luggage case 100 is in a rolled configuration 202. In FIG. 1B, luggage case 100 is in a second rolled configuration 202 having a more compact configuration or smaller interior volume 160. FIGS. 4A-4E show additional configurations, which are discussed further below. Luggage case 100 transitions between the unrolled configuration 200, shown in FIGS. 2, 4A, and 5A, and one or more rolled configurations 202 to selectively access interior volume 160 defined by soft side portion 130 and base portion 120.

[0050] The base portion 120 can be defined or disposed along a portion of the rear side 106 and / or bottom side 114 of the luggage case 100. For example, the base portion 120 can include a bottom portion 124 that defines or is disposed along the bottom side 114 of the luggage case 100. The base portion 120 includes a rear base portion 122 that extends upwardly from the bottom portion 124 or approximately perpendicular or perpendicular to the bottom portion 124. The rear base portion 122 is disposed along the rear side 106 of the luggage case 100. In one embodiment, the rear base portion 122 defines a portion of the rear side 106 of the luggage case 100. The rear base portion 122 and the bottom portion 124 are hinged at an intersection 126 to allow the base portion 120 to be foldable. For example, the rear base portion 122 and the bottom portion 124 can be foldably rotated about the intersection. In some embodiments, base portion 120 can be at least partially flexible at intersection portion 126 .

[0051] Base portion 120 may be a rigid or semi-rigid portion of luggage case 100. For example, base portion 120 may comprise a molded plastic or aluminum construction. Rear base portion 122 and bottom portion 124 may be formed of one or more piece panels or frames. For example, rear base portion 122 and / or bottom base portion 124 may be molded as a single piece or may be defined by two or more joined panels.

[0052] The soft side portion 130 may be coupled to, integral with, or extending from the base portion 120. The soft side portion 130 may be a flexible or semi-flexible portion of the luggage case 100. The soft side portion 130 may define or be at the top portion 112 of the luggage case 100 and may also be referred to as the top portion 130. The soft side portion 130 includes a roll closure or roll top portion 132. For example, the roll top portion 132 may be a fabric or other flexible portion that extends around the top portion 112 of the luggage case 100 in the unrolled configuration 202. The roll top portion 132 defines a roll top opening 134, shown in FIG. 2, providing access to the interior volume of the luggage case 100. The roll top portion 132 is a flexible structure configured to fold or roll on itself to open and close the opening 134. This configuration can provide a water-resistant seal or closure of the interior volume 160. In some embodiments, the entire soft side portion 130 can be flexible or rollable to aid in closing the opening 134. In some embodiments, the roll-top portion 132 optionally includes a second closure mechanism 136 to selectively close the roll-top opening 134. The second closure mechanism 136 can be a zipper, a hook-and-loop fastener, a snap structure, or the like. The second closure mechanism 136 can be disposed adjacent to or at the opening 134. For example, the second closure mechanism 136 can extend around a portion or the entire perimeter of the opening 134.

[0053] As the roll-top portion 132 rolls up, material can transfer from the back side 106 to the top side 112 of the luggage case 100. Thus, material or structure described as being on the back side 106 in one configuration can become the top side 112. Likewise, structure on the top 112 can transfer to the front side 104 or become folded or wrapped around the roll-top portion 132.

[0054] In some embodiments, the soft side portion 130 includes a front panel 116. The front panel 116 is disposed on or extends over the front side 104 of the luggage case 100. The front panel 116 extends from the roll-top portion 132 to the base portion 120. The soft side portion 130 can optionally include a front panel pocket 152. The front panel pocket 152 is disposed on or defined by the front panel 116. The front panel pocket 152 can be on the exterior of the luggage case 100. In some embodiments, the front panel pocket 152 is optionally or additionally disposed on the interior of the luggage case 100.

[0055] The soft side portions 130 can be covered with, include, or consist of a water-resistant exterior material. The water-resistant material may cover or extend over a portion of the base portion 120. As a result, the luggage case 100 can be at least partially water-resistant. By using a common material for the soft side portions 130 and the base portion 120, the luggage case 100 can have a common or unified aesthetic and thus can have more visual appeal.

[0056] The luggage case 100 may include one or more straps 138 extending from or coupled to the soft side portion 130. The straps 138 may be arranged in a spaced apart configuration on the back 106 of the soft side portion 130. The straps 138 may be arranged below the roll-top portion 132. The straps 138 may include a first or top strap 140 and a bottom or second strap 142. The first strap 140 and the second strap 142 may be spaced apart from each other and from the soft side portion 130 of the luggage case 100. For example, the first strap 140 may be spaced apart above or perpendicular to the second strap 142. Each strap 138 may define an opening 144 between the strap 138 and the soft side portion 130, where the strap is spaced apart from the soft side portion 130.

[0057] The luggage case includes a telescoping towing handle 180 and a wheel assembly 170 for rolling the luggage case 100. The luggage case 170 may include two or more wheel assemblies 170. Each wheel assembly 170 includes at least one wheel 172. The wheel assemblies 170 are disposed on a bottom side of the luggage case 100. For example, the wheel assembly 170 may be coupled to the base portion 120. In one embodiment, the wheel assembly 170 is coupled to the bottom portion 124 and / or the rear base portion 122.

[0058] The telescoping towing handle 180 can be extended from or retracted into the luggage case 100. For example, FIG. 1A illustrates the towing handle 180 in an exemplary extended position. FIG. 1B illustrates the towing handle 180 in a partially retracted position 186. The telescoping towing handle 180 can include at least one downtube assembly 182. In some embodiments, the towing handle 180 includes two or more downtube assemblies 182. The downtube assembly 182 includes an inner tube coupled to a handle grip and an outer tube coupled to a base assembly and configured to receive the inner tube. The towing handle 180 can be disposed on the rear side 106 of the luggage case 100. The base assembly of the downtube assembly 182 can be coupled to or included in the base portion 120. For example, a cavity or pocket 188 receives the downtube assembly in the base portion 130, such as the rear base portion 122. The downtube assembly 182 may be expandable from or contractible into a cavity or pocket 188 when in use or for storage. The cavity or pocket 188 may be an opening that can be closed by a zipper or hook and loop fastener.

[0059] The telescoping towing handle 180 can be located adjacent to, e.g., directly below, the strap 138. In operation or use, the soft side portion 130 is selectively coupled to the towing handle 182 by the strap 138. The telescoping towing handle 180 can be selectively extended or retracted, such as between an extended configuration 184 and a retracted configuration 186, to be coupled to or received in the space 144 between the strap and the rear side of the soft side portion 130. In some embodiments, the towing handle 180 can be coupled to or received in the space 144 between both the first strap 140 and the second strap 142. In some embodiments, the towing handle 180 can be coupled to or received in the space 144 of either the first strap 138 or the second strap 140. In some embodiments, the towing handle 180 may not be coupled to either the first strap 140 or the second strap 140. By coupling the towing handle 180 to the soft side 130, the towing handle 180 can provide structure and rigidity to the soft side 130 to support the contents of the luggage case 100 when the luggage case 100 is unfolded or contracted (i.e., in the rolled configuration 202 or the unrolled configuration 200). By selectively coupling the soft side and the towing handle 180, the size (e.g., the interior volume 160 or the exterior size) of the luggage case 100 can be selectively adjusted and customized. Furthermore, the selective coupling allows the strap 138 to be used for multiple purposes. For example, as shown in FIG. 1B, the first strap 140 can be used as a separate carry handle when not being used to engage the towing handle 180.

[0060] 2, 4C, 4D, and others, and with continued reference to FIG. 1A, luggage case 100 can include corresponding or cooperating engagement structures 148 and coupling structures 190 to secure luggage case 100 in one or more rolled configurations. Engagement structures 148 can be fasteners, buckles, or hooks. Engagement structures 148 can be coupled to or integral with top portion 130. For example, engagement structures 148 can be coupled to or extend from roll-top portion 132. In one embodiment, engagement structures 148 are located on left side 108 or right side 110 of roll-top portion 132. In some embodiments, engagement structures 148 are located at or adjacent to roll-top opening 134. By locating the engagement structures 148 on both sides (e.g., the left side 108 and the right side 110), the engagement structures 148 can remain exposed regardless of whether the roll-top portion 132 is in the unrolled configuration 200 or the rolled configuration 202.

[0061] A corresponding or cooperating coupling structure 190 can receive or be coupled to the engagement structure 148. The coupling structure 190 can be a loop or strap 190 for receiving the engagement structure 148. For example, the loop structure 190 can define two or more corresponding pairs of openings or holes 192, such as on corresponding or opposing sides of the luggage case 100. The loop structures 190 can be spaced or positioned along the height of the luggage case 100. For example, the loop structures 190 can be spaced along or extend from the left side 108 and the right side 110 of the luggage case 100. The luggage case 100 can include multiple loop structures 190. The loop structures 190 can be coupled to or defined by the soft side portion 130 or the bottom portion 120. In some embodiments, the loop structures 190 can extend from the soft side portion 130 to the base portion 120. In some embodiments, loop structure 190 and opening 192 may also be used as a side carry handle for luggage case 100. In some embodiments, engagement structure 148 and coupling structure 190 may be corresponding snap fasteners, hook and loop fasteners, or a variety of other coupling mechanisms.

[0062] In operation or use, the roll-top portion 132 can be transitioned from an unrolled configuration 200, as in FIG. 2, or a rolled configuration 202, as in FIG. 1A, 1B, to a second rolled configuration 202, such as between the multiple rolled configurations 202 shown in FIGS. 1A, 1B. To secure the roll-top portion 132 to the rolled configuration 202, the roll-top portion 132 can be folded or rolled up, with the engagement structures 148 exposed (e.g., extending from both sides of the luggage case 100). The roll-top portion 132 can be rolled up, such as toward the bottom 114, until the interior volume 160 is sized to accommodate the contents of the luggage case 100. In such an embodiment, the soft side portion 130 can be rolled up in addition to the roll-top portion 132. In some embodiments, the roll-top portion 132 can be rolled up until the exterior size of the luggage case 100 is the desired volume or height. After a desired size of luggage case 100 is achieved, engagement structure 148 can be coupled to loop structure 190 to secure roll-top portion 134. Thus, luggage case 100 can be placed in rolled configuration 202. In some embodiments, engagement structure 148 is adjustable, such as by an adjustable strap, for fine-tuning the size of luggage case 100 or to compress the contents of interior volume 160.

[0063] 3, the luggage case 100 can include a closure assembly 230 that provides selective access to the interior volume 160. The closure assembly 230 can extend between at or near the roll-top portion 132 and at or near the base portion 120. The closure assembly 230 can be a zipper. In some embodiments, the closure assembly 230 can be various other types of selectively engageable fasteners, such as hook-and-loop fasteners, snap fasteners, and the like. The closure assembly 230 can be disposed on or extend around a portion of the front panel 116 of the soft side portion 130. The closure assembly 230 can extend around a portion or the entire perimeter 118 of the front panel 116. In one embodiment, the closure assembly 230 is a U-shaped or three-sided closure assembly 230 that can provide selective access to the interior volume 160. In some embodiments, the closure assembly 230 can be another three-sided shape. For example, the U-shaped closure assembly 230 may include two long sides 232 extending from the roll-top portion 132 to the base portion 120. A base or short side 234 may extend between the long sides 232. The base 234 of the U-shaped closure assembly 230 may be disposed adjacent the bottom 124 of the base portion 120.

[0064] The closure assembly 230 extends from the base portion to provide access to the interior volume 160 whether the luggage case 100 is in the rolled configuration 202 or the unrolled configuration 200. For example, by positioning a portion of the closure assembly 230, such as the base 234 of the closure assembly 230, at or near the base portion 120, opposite the roll-top portion 132 and the opening 134, the closure assembly 230 can be accessed and selectively opened in the rolled configuration 202. The closure assembly 230 can also allow contents to be packed into or removed from the interior volume 160 of the luggage case 1000 in both an upright position (e.g., with the top side 112 facing up) or with the back side 106 facing down or resting on the ground.

[0065] 4A-4F show various unrolled and rolled configurations 200 and 202 of luggage case 100. FIGS. 5A-5C show rear views of some example configurations 200, 202 of luggage case 100 shown in FIGS. 4A-4F. Configurations 200, 202 can accommodate common baggage sizes defined by a transportation company or service, such as an airline, bus, or train line. In some embodiments, luggage case 100 has a width W, such as from left side 108 to right side 110, between 30 cm and 50 cm, in one example, 40 cm. The width can be adjusted by changing the height or depth of luggage case 100. In some embodiments, luggage case 100 has a height or length H, such as from bottom side 114 to top side 112, between 40 cm and 90 cm, with each configuration defining one or more possible heights H. In some embodiments, luggage case 100 has an adjustable depth D, such as from front side 104 to back side 106, between 5 cm and 50 cm, as shown in Figures 1A and 6.

[0066] 4A and 5A show front and rear views of luggage case 100 in an unrolled configuration 200. As described herein, in the unrolled configuration 200, roll-top portion 132 can be unrolled or unfolded to allow access to interior volume 160. In one example, in the unrolled configuration 202, luggage case 100 has a height H of 82 cm, a width W of 40 cm, and a depth D of 25 cm.

[0067] As shown in FIG. 5A , a telescoping towing handle 180 can extend from a hollow pocket 188 at or adjacent to the base portion 120 to engage the straps 138. For example, the towing handle 180 can be received by either the first strap 140 or the second strap 142, or both. The towing handle 180 and the base portion 120, such as the rear base portion 124 and / or the bottom portion 124, can provide structural support or rigidity to the luggage case 100. The support or rigidity can help hold the luggage case 100 open for packing items or contents. After the luggage case 100 is filled, the roll-top portion 132 can be selectively closed by the second closure mechanism 136.

[0068] FIG. 4B is a front view of an exemplary roll configuration 208. The roll configuration 208 of the luggage case 100 of FIG. 4B may correspond to a cargo or check-in or high-capacity luggage arrangement 208 of the luggage case 100. In the high-capacity configuration 208, the roll-top portion 132 may be fully rolled or folded to close the opening 134. In some embodiments, the roll-top portion 132 may include a second closure mechanism 136 for sealing the opening 134. The second closure mechanism 136 may be a zipper, hook-and-loop fastener, snaps, or straps for selectively sealing the roll-top portion 132 to close the opening 134. In the high-capacity configuration 208, the engagement structures 148 of the roll-top portion 132 may be coupled to define a carry handle.

[0069] 4C-4F, certain of the roll configurations 202 can be defined at least in part by loop structures 190 to which the closure structures 148 are coupled. The loop structures 190 can be spaced along the height of the luggage case 100. Loop structures 190 closer to the bottom 114 or base portion 120 allow for a smaller configuration of the luggage case 100 having a smaller interior volume 160 compared to loop structures 190 located closer to the top 112 or roll-top portion 132, which allow for a larger volume configuration. For example, the luggage case 100 can include a first or top loop structure 190a, a second loop structure 190b, a third loop structure 190c, or a fourth loop structure 190d, etc.

[0070] FIG. 4C is a front view of an exemplary roll configuration 202. The roll configuration 202 of the luggage case 100 of FIG. 4B can correspond to a checked size configuration 210 of the luggage case 100. In the checked configuration 210, the engagement structure 148 can be coupled to the first or uppermost loop structure 190a. In the checked configuration 210, only the roll-top portion 132 can be rolled up, with the remainder of the soft side portion 130 defining an interior volume 160 with the base portion 120. The interior volume 160 of the checked configuration 210 can be of a smaller volume or smaller overall size than the cargo configuration 208. In one example, the checked configuration 210 has a height H of about 75 cm, a width W of 40 cm, and a depth D of 25 cm.

[0071] FIG. 4D shows a front view of the luggage case 100 in the rolled configuration 202 defining a carry-on or stowable configuration 212. FIG. 5B shows a rear view of the carry-on configuration 212. In the carry-on configuration 212, the securing structure 148 can be coupled to either the second loop structure 190b or the third loop structure 190b. To define the carry-on configuration 212, the roll-top portion 132 and additional portions of the soft side portion 130 can be folded or rolled up. In some embodiments of the carry-on configuration 212, the second strap 142 can be coupled to the towing handle 180, as shown in FIG. 5B. In this configuration, the first strap 140 is not coupled to the towing handle 180. Instead, the first strap 140 can be positioned at the top 112 of the luggage case 100 and used as a carry handle. By selectively engaging straps 138, towing handle 180 can provide structural support proportional to the size or height H of interior volume 160 of luggage case 100. Interior volume 160 of carry-on 212 can be of a smaller volume or smaller exterior size than that of checked configuration 210. In one embodiment of carry-on configuration 212, luggage case 100 has a height H of 55 cm, a width W of 40 cm, and a depth D of 25 cm.

[0072] 4E and 5C show a tote or smaller carry-on configuration 214. In the tote configuration 214, the engagement structure 148 can be coupled to the bottom or fourth loop structure 190d. In the tote configuration 214, the towing handle 180 can have one strap 138 coupled thereto or none coupled thereto. For example, the second or bottom strap 142 can be disposed at the top 112 of the bag and used as a carry handle. In such an embodiment, the rear base portion 122 can define all or most of the rear side 106 of the luggage case 100. In the tote configuration 214, the height, depth, or width of the base portion 120 can define the height, depth, or width of the luggage case 100, respectively. The interior volume 160 of the tote configuration 214 can have a smaller capacity or a smaller overall size than the carry-on configuration 212. In some embodiments, luggage case 100 may optionally include shoulder straps as shown in FIG. 4E.

[0073] As can be seen, the closure assembly 230 can be accessible in each of the unrolled and rolled configurations 200 and 202. Even in the most compact tote configuration 214, the base portion 234 of the closure assembly 230 can be accessible or exposed, for example as shown in FIG. 4E. In some embodiments, the roll-top portion 132 may be restricted from folding or rolling up to the bottom portion 124. Thus, the contents within the interior volume 160 can be accessible by the closure assembly 230 in all of the rolled and unrolled configurations 202 and 200.

[0074] In some embodiments, luggage case 100 is configurable to fold into optional compact configuration 220. Figures 4F, 6A, and 6B show example exterior views of luggage case 100 in optional compact configuration 220, with Figure 4F showing luggage case 100 in a storage pouch. Compact configuration 220 may be a folded configuration of luggage case 100 in which luggage case 100 is positioned for storage.

[0075] As shown in Figures 6A and 6B, luggage case 100 can be placed in a folded or compact configuration 220. Figure 6A shows a perspective view of compact configuration 220. In compact configuration 220, luggage case 100 can be stowed or placed inside another luggage case 100. For example, luggage case 100 can have a smaller height H and depth D. Width dimension W can be the same or smaller compared to rolled configuration 202.

[0076] To define a compact configuration, the soft side portions 130 can be rolled up or folded under the top of the rear base portion 122. The telescoping towing handle 180 can be retracted and / or disposed within a cavity or pocket 188. The base portion 120 can be folded about an intersection or hinge 126. For example, the bottom portion 124 can be folded about the intersection 126 to define the front side 104 of the luggage case 100. In some embodiments, the soft side portions 130 can be disposed between the rear base portion 122 and the bottom portion 124. In such embodiments, the rear base portion 122 and the bottom portion 124 can compress the soft side portions 130 to help reduce the depth and overall size of the luggage case 100.

[0077] In some embodiments, the base portion 120 can include a second strap 222 having a hook and a corresponding coupling structure 224, such as a loop. The second strap 222 or coupling structure 224 can be disposed on the rear base portion 122 and the bottom portion 124 in an interengaging manner to maintain the compact configuration 220. In one embodiment, the second strap 222 is coupled to the bottom portion 124, and the coupling structure 224 is disposed adjacent to the cavity or pocket 188.

[0078] The wheel assembly 170 of the luggage case 100 can help the luggage case fold into the compact configuration 220. For example, the wheel assembly 170 can be foldable. FIG. 6B shows a close-up view of the foldable wheel assembly 170. The foldable wheel assembly 170 can include a first portion 174 and a second portion 176. The wheel 172 can be disposed between or coupled to either the first portion 174 and the second portion 176. The first portion 174 and the second portion 176 can be movable relative to one another. For example, the first portion 174 can be coupled to the bottom portion 124 and the second portion 176 can be coupled to the rear base portion 122. In such an embodiment, the first portion 174 and the second portion 176 can be folded or rotated about the intersection portion 126 of the base portion 120. As a result, the wheel assembly 170 can be folded in a similar manner when the base portion 120 is in the compact configuration 220.
