TECHNICAL FIELD
The present disclosure relates to hard-sided luggage.
BACKGROUND
The following paragraphs are not an admission that anything discussed in them is prior art or part of the knowledge of persons skilled in the art.
Hard-sided luggage has become increasingly popular in recent years. Hard-sided luggage can provide several benefits versus soft-sided baggage, including attractiveness, durability and light weight. One important benefit to using hard-sided luggage is that contents tend to be well protected. Hard-sided luggage can include features such telescoping handles, and swivel wheels that allow for easy maneuvering. Hard-sided luggage can also include a secure locking mechanism, including TSA-approved locks, for example. Internally, hard-sided luggage can include features such as dividers, pockets and straps to hold its contents in place.
Hard-sided luggage can be constructed of several different materials, including aluminum, polycarbonate, ABS and polypropylene. Hard-sided luggage is available in endless colors and designs, and the shells can be scratch-resistant, dent-resistant, and generally waterproof.

The claimed inventions are not limited to apparatuses and methods having all of the features of any one apparatus or method described below or to features common to multiple or all of the apparatuses or methods described below. It is possible that an apparatus or method described below is not an embodiment of any claimed invention. Any invention disclosed in an apparatus or method described below that is not claimed in this document may be the subject matter of another protective instrument, and the applicant(s), inventor(s) and/or owner(s) do not intend to abandon, disclaim or dedicate to the public any such invention by its disclosure in this document.
Referring to FIGS. 1 and 2, an example of a hard-sided luggage bag is shown generally at 10. The bag 10 extends in a depth direction 12 between a front side 14 and a back side 16. The bag 10 extends in a width direction 18 between a left side 20 and a right side 22. The bag 10 extends in a height direction 24 between a top side 26 and a bottom side 28.
In the example illustrated, the bag 10 includes a rearward shell portion 30 and a forward shell portion 32. The shell portions 30, 32 can be generally complementary in size and shape. The shell portions 30, 32 can be formed of a variety of materials, including, for example but not limited to, aluminum, polycarbonate, ABS, polypropylene, and composites thereof. The shell portions 30, 32 can include an interior lining formed of fabric material.
Referring particularly to FIG. 3, the shell portions 30, 32 are coupled together to enclose a storage compartment 34. The forward shell portion 32 includes an access opening 36 formed therein. The access opening 36 permits access to the storage compartment 34. A lid 38 is coupled to the forward shell portion 32. In an open position, as shown in FIG. 3, the lid 38 allows access to the storage compartment 34 through the access opening 36. In a closed position, as shown in FIGS. 1 and 2, the lid 38 covers the access opening 36.
In the example illustrated, the lid 38 is shown to be formed of a shell portion, generally in continuity with the forward shell portion 32. In some examples, the lid 38 can include one or more zippered pockets arranged along an interior side thereof.
Alternatively, in soft-sided examples, the lid can be formed of at least one fabric portion (not shown), which can be formed of, for example but not limited to, polyester, nylon or polypropylene fabric materials. In such examples, the at least one fabric portion can include one or more zippered pockets, that can be accessible from the exterior of the bag. In other hybrid examples, the lid can be formed of a combination of at least one shell portion and fabric materials.
Furthermore, in yet other examples, the lid can be formed of two portions (or more), that are configured to open and close independently of one another. In such examples, the lid portions can be releasably joined to one another, e.g., with a zipper or another suitable closure mechanism, roughly midway across the access opening between a bottom edge and a top edge. Alternatively, the access opening can include two separate sections, separated by a strut element (not shown) that, for example, extends across the access opening between a left edge and a right edge. In such examples, each of the lids can be releasably joined to the strut element, and coupled to the forward shell portion along one of its edges by respective hinges.
Referring back to FIGS. 1 and 2, and with continued reference to FIG. 3, the lid 38 is releasably joined to the forward shell portion 32 along a bottom edge 40 of the access opening 36. The bottom edge 40 is shown to be spaced apart a first dimension 42 (shown in FIG. 2) from the bottom side 28 in the height direction 24. Thus, in the height direction 24, the access opening 36 has a second dimension 44 (shown in FIG. 2) that is less than a third dimension 46 (shown in FIG. 1) of the bag 10 between the top and bottom sides 26, 28. With the access opening 36 and the lid 38 spaced apart from the bottom side 28 in this manner, a lower portion of the bag 10 can provide a relatively rigid structure, which can be maintained when the lid 38 is in the open position.
In the example illustrated, the bottom edge 40 extends generally across the front side 14 between the left and right sides 20, 22. The lid 38 is further releasably joined to the forward shell portion 32 along a left edge 48, a top edge 50 and a right edge 52 of the access opening 36 that extend generally across the left, top and right sides 20, 26, 22, respectively.
The lid 38 is releasably joined to the forward shell portion 32 along the edges 40, 48, 50, 52 by a lid closure mechanism 54. In the example illustrated, the lid closure mechanism 54 includes a lid zipper 55.
The lid 38 is shown to be releasably joined only partly along the left edge 48, as the lid 38 is connected to the forward shell portion 32 generally along the left edge 48 by a hinge 56. In other examples, a hinge connecting the lid 38 and the forward shell portion 32 can be arranged on the bottom edge 40, which can reduce the risk of contents falling out of the access opening 36 if the lid 38 is opened while the bag 10 is disposed in an upright position. In such examples, the bag 10 can include gussets (not shown), provided alongside the edges 48, 52, to help to prevent contents from falling out of the access opening 36 when the lid 38 is opened and the bag 10 is disposed in the upright position. In yet other examples, a hinge connecting the lid 38 and the forward shell portion 32 can be arranged on the top edge 50, or on the right edge 52. Various configurations are possible.
In the depth direction 12, the edges 48, 50, 52 are arranged generally adjacent to the front side 14. As shown in FIG. 4, in the depth direction 12, the access opening 36 has a fourth dimension 58 that is substantially less than a fifth dimension 60 of the bag 10 between the back side 14 and the edges 48, 50, 52. Thus, referring back to FIG. 3, users can have access to almost the full depth of the storage compartment 34 through the access opening 36. Furthermore, in some examples, as illustrated, the sides 20, 26, 22 can present a generally uniform dimension in the depth direction 12 so that the storage compartment 34 is of a generally uniform depth over the edges 48, 50, 52 of the access opening 36.
Referring to FIGS. 1 and 1A, an interior edge of the forward shell portion 32 defines a vertical line 61, the left edge 48 defines a vertical line 63, and the bottom edge 40 defines a horizontal line 65 and a vertical line 67 at the front side of the bag. In the example illustrated, the access opening 36 includes a curved bottom corner 69 that is arranged intermediate of the bottom edge 40 and the left edge 48. A vertical line 71 intersects a boundary between the curved bottom corner 69 and the bottom edge 40. The lines 61, 63, 67, 71 are each parallel to the height direction 24, and the line 65 is parallel to the depth direction 12. In the example illustrated, the bottom edge 40 extends horizontally parallel to the depth direction 12 between the front side of the bag and the curved corner 69. As illustrated, a horizontal dimension 73 between the lines 61, 63 is less than a horizontal dimension 75 between the lines 63, 67, and a horizontal dimension 77 between the lines 63, 71 is less than a horizontal dimension 79 between the lines 71, 67. FIG. 6 shows generally the same configuration on the other side of the bag 10.
Referring now to FIG. 5, an expansion section 62 is shown to be connected to inner edges 64, 66 of the shell portions 30, 32, respectively. In the example illustrated, the expansion section 62 includes an expansion zipper 68, which, when released, increases space between the inner edges 64, 66 thereby increasing a depth dimension of the bag 10 (i.e. in the depth direction 12).
In the example illustrated, the expansion section 62 is shown to be generally intermediate the front and back sides 14, 16 so that, in the depth direction 12, a sixth dimension 70 of the rearward shell portion 30 between the back side 16 and the inner edge 64 is similar to a seventh dimension 72 of the forward shell portion 32 between the inner edge 66 and the front side 14. In this manner, a center of gravity of the bag 10 can remain generally balanced between the sides 14, 16 once the expansion zipper 68 is released.
Furthermore, referring to FIGS. 3, 4 and 5, the expansion section 62 is shown to be generally spaced apart from the access opening 36 and the lid 38, with the edges 40, 48, 50, 52 of the access opening 36 being generally intermediate the expansion section 62 and the front side 14. For users, this can help to reduce confusion between the lid zipper 55 and the expansion zipper 68.
Referring now to FIGS. 6 and 7, the bag 10 includes wheels 74 arranged on the bottom side 28. Some or all of the wheels 74 can be swivel wheels. In the example illustrated, two of the wheels 74 are fixed to the rearward shell portion 30, and two of the wheels 74 are fixed to the forward shell portion 32. With the lid 38 spaced apart from the bottom side 28, the lid 38 can be opened without interfering with the wheels 74. Furthermore, as mentioned above, with the access opening 36 and the lid 38 spaced apart from the bottom side 28, a lower portion of the bag 10 can provide a relatively rigid structure, which can bear the weight of the bag 10 and its contents, and can serve as a stable base for attachment of the wheels 74.
In the example illustrated, the bag 10 further includes a top handle 76, a side handle 78 and feet 80. As shown, the top handle 76 can be retractable, and suitable for guiding the bag 10 on the wheels 74.
Referring now to FIGS. 8, 9 and 10, an example of a hard-sided luggage bag is shown generally at 110. In the example illustrated, the bag 110 includes a rearward shell portion 130 and a forward shell portion 132. The shell portions 130, 132 can be generally complementary in size and shape. The shell portions 130, 132 can be formed of a variety of materials, including, for example but not limited to, aluminum, polycarbonate, ABS, polypropylene, and composites thereof. The shell portions 130, 132 can include an interior lining formed of fabric material.
Referring particularly to FIG. 10, the shell portions 130, 132 are coupled together to enclose a storage compartment 134. The forward shell portion 132 includes an access opening 136 formed therein. The access opening 136 permits access to the storage compartment 134. A lid 138 is coupled to the forward shell portion 132. In an open position, the lid 138 permits access to the storage compartment 134 through the access opening 136. In a depth direction, edges of the access opening 136 are arranged generally adjacent to a front side of the bag 110. Thus, users can have access to almost the full depth of the storage compartment 134 through the access opening 136. Furthermore, in some examples, as illustrated, the sides of the bag 110 can present a generally uniform dimension in the depth direction so that the storage compartment 134 is of a generally uniform depth over the edges of the access opening 136. In a closed position, as shown in FIG. 8, the lid 138 covers the access opening 136.
In the example illustrated, referring again to FIGS. 8, 9 and 10, the lid 138 is shown to be formed of a shell portion, generally in continuity with the forward shell portion 132. Alternatively, in some examples, the lid 138 can be formed of at least one shell portion, at least one fabric portion, or a combination thereof.
The lid 138 is releasably joined to the forward shell portion 132 along edges of the access opening 136 by a lid closure mechanism 154. In the example illustrated, the lid closure mechanism 54 includes a lid zipper 55.
The lid 138 is shown to be releasably joined only partly along a bottom edge 140 of the access opening 136 (FIG. 10), as the lid 138 is connected to the forward shell portion 132 generally along the bottom edge 140 by a hinge 156. The hinge 156 is spaced apart from a bottom side of the bag 110 in a height direction.
Referring particularly to FIG. 9, the arrangement of the hinge 156 can help to reduce the risk of contents falling out of the access opening 136 if the lid 138 is opened while the bag 110 is disposed in an upright position. The bag 110 can include releasable support straps 180 coupled between the lid 138 and the forward shell portion 132. Each of the support straps 180 can include a first member fixed to the lid 138, and a second member fixed to the forward shell portion 132 and attached to the first member. In some examples, the first and second members of the support straps 180 can be attached to each other with a snap buckle. The releasable support straps 180 can be configured to maintain the lid 138 in a partially opened position (shown in FIG. 9), as opposed to a fully opened position (shown in FIG. 10), which can also help to reduce the risk of contents falling out of the access opening 136.
The rearward shell portion 130 is releasably joined to the forward shell portion 132 along a main joint 182 by a main closure mechanism 183. In the example illustrated, the main closure mechanism 183 includes a main zipper 185.
The storage compartment 134 can be accessed by releasing the main closure mechanism 183. Thus, in some examples, the storage compartment 134 can be accessed in two separate ways, namely, through the access opening 136 by releasing the lid closure mechanism 154, or through the main joint 182 by releasing the main closure mechanism 183. The main joint 182 is shown to be generally intermediate front and back sides of the bag 110 so that, once the main closure mechanism 183 is released, the bag 110 can be opened into two roughly equal halves (defined by the rearward shell portion 130 and the forward shell portion 132). Furthermore, the main zipper 185 is shown to be generally spaced apart from the lid zipper 155, which can help to reduce confusion between the main zipper 185 and the lid zipper 155. A hinge (not shown) can also be provided to connect the shell portions 130, 132 together.
In some examples, referring again to FIG. 10, the bag 110 can include a divider 184, which is shown to be partially detached and flipped to one side of the bag 110. The divider 184 can be planar and flexible, e.g., formed of a fabric material, and can be shaped to correspond with an interior cross-section of the storage compartment 134. The divider 184 can be releasably suspended in the storage compartment 134, for example, by a divider zipper 186, which joins edges of the divider 184 to a flap 188 that is fixed to interior side walls of the storage compartment 134. In some examples, a pocket (not shown) can be arranged within the storage compartment 134 for stowing the divider 184 when it is at least partially detached from the flap 188.
When the divider 184 is attached (e.g., by zipping up the divider zipper 186), the divider 184 can divide the storage compartment 134 into two substantially separate subcompartments. In the example illustrated, the divider 184 divides the storage compartment into a front subcompartment (accessible through the lid 138), and a rear subcompartment (accessible through the main joint 182). In some examples, a volume of the front subcompartment can be substantially less than a volume of the rear subcompartment. When the divider 184 is detached, as shown in FIG. 10, generally the full volume of the storage compartment 134 can be accessible to the user by opening either the lid closure mechanism 154 or the main closure mechanism 183.
As illustrated, within the storage compartment 134, the bag 110 can further include at least one interior zippered pocket 190, and one or more restraint straps 192.
Referring again to FIGS. 8 and 9, the bag 110 is also shown to include wheels 174 arranged on a bottom side, and some or all of the wheels 174 can be swivel wheels. In the example illustrated, two of the wheels 174 are fixed to the rearward shell portion 130, and two of the wheels 174 are fixed to the forward shell portion 132. The bag 110 can further include a top handle 194, a retractable handle 176, a side handle 178, and feet 180.
Referring now to FIGS. 11 and 12, an example of a hard-sided luggage bag is shown generally at 210. In the example illustrated, the bag 210 includes a rearward shell portion 230 and a forward shell portion 232. The shell portions 230, 232 can be generally complementary in size and shape. The shell portions 230, 232 can be formed of a variety of materials, including, for example but not limited to, aluminum, polycarbonate, ABS, polypropylene, and composites thereof. The shell portions 230, 232 can include an interior lining formed of fabric material.
Referring particularly to FIG. 12, the shell portions 230, 232 are coupled together to enclose a storage compartment 234. The forward shell portion 232 includes an access opening 236 formed therein. The access opening 236 permits access to the storage compartment 234. A lid 238 is coupled to the forward shell portion 232. In an open position, the lid 238 allows access to the storage compartment 234 through the access opening 236. In a closed position, as shown in FIG. 11, the lid 238 covers the access opening 236.
In the example illustrated, the lid 238 is shown to be formed of a shell portion, and extends generally outwardly relative to the forward shell portion 232. Edges of the access opening 236 are arranged generally adjacent to a front side of the bag 210. Thus, users can have access to almost the full depth of the storage compartment 234 through the access opening 236. Furthermore, the storage compartment 234 is of a generally uniform depth along the edges of the access opening 236.
The lid 238 is releasably joined to the forward shell portion 232 along edges of the access opening 236 by a lid closure mechanism 254. In the example illustrated, the lid closure mechanism 254 includes lid clasps 257. In such examples, the lid closure mechanism 254 can also include a rigid frame which extends along edges of the lid 238 and/or the edges of the access opening 236 to ensure that the lid 238 correctly mates with the forward shell portion 232 when closed.
The lid 238 is shown (FIG. 11) releasably joined only partly along the left edge of the access opening 236, as the lid 238 is connected to the forward shell portion 232 generally along the left edge by a hinge 256.
The rearward shell portion 230 is releasably joined to the forward shell portion 232 along a main joint 282 by a main closure mechanism 283. In the example illustrated, the main closure mechanism 283 includes main clasps 287. In such examples, the main closure mechanism 283 can also include a rigid frame which extends along inner edges of the shell portions 230, 232 to ensure that they correctly mate when closed.
The storage compartment 234 can be accessed by releasing the main closure mechanism 283. Thus, in some examples, the storage compartment 234 can be accessed in two separate ways, namely, through the access opening 236 by releasing the lid closure mechanism 254, or through the main joint 282 by releasing the main closure mechanism 283. The main joint 282 is shown to be generally intermediate front and back sides of the bag 210 so that, once the main closure mechanism 283 is released, the bag 210 can be opened into two roughly equal halves (defined by the rearward shell portion 230 and the forward shell portion 232). Furthermore, the lid clasps 257 are shown to be generally spaced apart from the main clasps 287, which can help to reduce confusion between the lid closure mechanism 254 and the main closure mechanism 283. A hinge (not shown) can also be provided to connect the shell portions 230, 232 together.
In the example illustrated, referring particularly to FIG. 12, the bag 210 includes a divider 284. The divider 284 can be planar and flexible, e.g., formed of a fabric material, and can be shaped to correspond with an interior cross-section of the storage compartment 234. The divider 284 can be releasably suspended in the storage compartment 234, for example, by a divider zipper 286, which joins edges of the divider 284 to a flap 288 that is fixed to interior side walls of the storage compartment 234. In some examples, a pocket (not shown) can be arranged within the storage compartment 234 for stowing the divider 284 when it is at least partially detached from the flap 288.
When the divider 284 is attached (i.e. by zipping up the divider zipper 286), the divider 284 can divide the storage compartment 234 into two substantially separate subcompartments. In the example illustrated, the divider 284 divides the storage compartment 234 into a front subcompartment (accessible through the lid 238), and a rear subcompartment (accessible through the main joint 282). In some examples, a volume of the front subcompartment can be substantially less than a volume of the rear subcompartment. When the divider 284 is detached, as shown in FIG. 12, generally the full volume of the storage compartment 234 can be accessible to the user by opening either the lid closure mechanism 254 or the main closure mechanism 283.
In the example illustrated, the divider 284 includes a zippered pocket 296. In some examples, the zippered pocket 296 can span generally the full length and width of the divider 284. Furthermore, as illustrated, the lid 238 can include a zippered pocket 298 arranged along an interior side thereof. The zippered pocket 298 can span generally the full length and width of the lid 238.
The bag 210 is shown to include wheels 274 arranged on a bottom side, and some or all of the wheels 274 can be swivel wheels. In the example illustrated, two of the wheels 274 are fixed to the rearward shell portion 230, and two of the wheels 274 are fixed to the forward shell portion 232. The bag 210 is also shown to include a top handle 294, a retractable handle 276, a side handle 278, and feet 280.
Referring now to FIGS. 13, 14, 15 and 16, an example of a hard-sided luggage bag is shown generally at 310. In the example illustrated, the bag 310 includes a rearward shell portion 330 and a forward shell portion 332. The shell portions 330, 332 can be generally complementary in size and shape. The shell portions 330, 332 can be formed of a variety of materials, including, for example but not limited to, aluminum, polycarbonate, ABS, polypropylene, and composites thereof. The shell portions 330, 332 can include an interior lining formed of fabric material.
Referring particularly to FIG. 16, the shell portions 330, 332 are coupled together to enclose a storage compartment 334. The forward shell portion 332 includes an access opening 336 formed therein. The access opening 336 permits access to the storage compartment 334. A lid 338 is coupled to the forward shell portion 332. In an open position, the lid 338 allows access to the storage compartment 334 through the access opening 336. In a depth direction, edges of the access opening 336 are arranged generally adjacent to a front side of the bag 310. Thus, users can have access to almost the full depth of the storage compartment 334 through the access opening 336. Furthermore, in some examples, as illustrated, the sides of the bag 310 can present a generally uniform dimension in the depth direction so that the storage compartment 334 is of a generally uniform depth over the edges of the access opening 336. In a closed position, the lid 338 covers the access opening 336.
Referring particularly to FIGS. 13 and 14, the lid 338 is formed of a shell portion, generally in continuity with the forward shell portion 332. Alternatively, in some examples, the lid 338 can be formed of at least one shell portion, at least one fabric portion, or a combination thereof.
The lid 338 is releasably joined to the forward shell portion 332 along edges of the access opening 336 by a lid closure mechanism 354. In the example illustrated, the lid closure mechanism 354 includes a lid zipper 355.
The lid 338 is shown to be releasably joined only partly along a bottom edge of the access opening 336, as the lid 338 is connected to the forward shell portion 332 generally along the bottom edge by a hinge 356 (FIG. 16). The hinge 356 is spaced apart from a bottom side of the bag 310 in a height direction.
The rearward shell portion 330 is releasably joined to the forward shell portion 332 along a main joint 382 by a main closure mechanism 383. In the example illustrated, the main closure mechanism 383 includes a main zipper 385.
The storage compartment 334 can be accessed by releasing the main closure mechanism 383. Thus, in some examples, the storage compartment 334 can be accessed in two separate ways, namely, through the access opening 336 by releasing the lid closure mechanism 354, or through the main joint 382 by releasing the main closure mechanism 383.
The main joint 382 is shown to be generally intermediate front and back sides of the bag 310 so that, once the main closure mechanism 383 is released, the bag 310 can be opened into two roughly equal halves (defined by the rearward shell portion 330 and the forward shell portion 332). Furthermore, the main closure mechanism 383 is shown to be generally spaced apart from the lid closure mechanism 354, which can help to reduce confusion between the main zipper 385 and the lid zipper 355. A hinge (not shown) can also be provided to connect the shell portions 330, 332 together.
With continued reference to FIGS. 13 and 14, an expansion section 362 is shown to be connected to an inner edge of the forward shell portion 332 and a forward edge of the main joint 382. In the example illustrated, the expansion section 362 includes an expansion zipper 368, which, when released, increases space between the inner edge of the forward shell portion 332 and the forward edge of the main joint 382, thereby increasing a depth dimension of the bag 310.
In the example illustrated, the expansion section 362 is shown to be arranged adjacent to the main joint 382, but generally intermediate front and back sides of the bag 310, so that a center of gravity of the bag 310 can remain generally balanced between the front and back sides once the expansion zipper 368 is released.
In some examples, referring again to FIG. 16, the bag 310 can include a divider 384, which is shown to be partially detached and rolled up to one side of the storage compartment 334. The divider 384 can be planar and flexible, e.g., formed of a fabric material, and can be shaped to correspond with an interior cross-section of the storage compartment 334. The divider 384 can be releasably suspended in the storage compartment 334, for example, by a divider zipper, which joins edges of the divider 384 to one or more flaps that are fixed to interior side walls of the storage compartment 334. In some examples, a pocket (not shown) can be arranged within the storage compartment 334 for stowing the divider 384 when it is at least partially detached from the one or more flaps.
When the divider 384 is attached (e.g., by zipping up the divider zipper), the divider 384 can divide the storage compartment 334 into two substantially separate subcompartments. In the example illustrated, the divider 384 divides the storage compartment into a front subcompartment (accessible through the lid 338), and a rear subcompartment (accessible through the main joint 382). In some examples, a volume of the front subcompartment can be substantially less than a volume of the rear subcompartment. When the divider 384 is detached, as shown in FIG. 16, generally the full volume of the storage compartment 334 can be accessible to the user by opening either the lid closure mechanism 354 or the main closure mechanism 383.
In the example illustrated, the hinge 356 being arranged on the bottom edge of the access opening 336 can help to reduce the risk of contents falling out of the access opening 336 if the lid 338 is opened while the bag 310 is disposed in an upright position. The bag 310 includes gussets provided alongside edges of the access opening 336. In the example illustrated, the gussets are formed by first members 391 fixed to the lid 338, and second members 393 fixed to the forward shell portion 332 and attached to the first members 391. In some examples, the first and second members 391, 393 can be attached using a hook-and-loop fastener. The first and second members 391, 393 can be configured to maintain the lid 338 in a partially opened position (shown in FIGS. 13, 14 and 15), as opposed to a fully opened position (shown in FIG. 16), which can also help to reduce the risk of contents falling out of the access opening 336.
As illustrated, within the storage compartment 334, the bag 310 can further include at least one interior zippered pocket 390, and one or more restraint straps 392.
The bag 310 is shown to include wheels 374 arranged on a bottom side, and some or all of the wheels 374 can be swivel wheels. In the example illustrated, two of the wheels 374 are fixed to the rearward shell portion 330, and two of the wheels 374 are fixed to the forward shell portion 332. The bag 310 is also shown to include a top handle 394, a retractable handle 376, and a side handle 378.
While the above description provides examples of one or more apparatuses or methods, it will be appreciated that other apparatuses or methods may be within the scope of the accompanying claims.
