DETAILED DESCRIPTION

Aspects and embodiments are directed to an improved carrying article, for example a luggage article, in particular an expandable hardside luggage article which has a frame. In some embodiments, the frame is configured for attachment to a gusset that in combination with the frame provides an expandable frame assembly having a contracted position and an expanded position of the expandable frame assembly. In some embodiments, the expandable frame assembly further includes a bracing mechanism that locks the frame assembly in the contracted position and the expanded position. In some embodiments, the bracing mechanism is a sliding bracing mechanism. In some embodiments, the sliding bracing mechanism includes a tongue and groove assembly. In some embodiments, the expandable frame assembly is configured for use with an article of luggage. In some embodiments, the expandable frame assembly is used with a hard-shell article of luggage. In some embodiments, the hard-shell of the hard-shell article of luggage includes metal. In some embodiments, the hard-shell includes aluminum.

Other aspects and embodiments are directed to an improved carrying article, such as an article of luggage having an improved frame. In some embodiments, the improved frame is attached to a gusset that in combination with the frame provides an expandable frame assembly having a contracted position and an expanded position of the article of luggage. In some embodiments, the article of luggage includes a bracing mechanism that locks the frame in the contracted position and the expanded position. In some embodiments, the bracing mechanism is a sliding bracing mechanism. In some embodiments, the sliding bracing mechanism includes a tongue and groove assembly. In some embodiments, the article of luggage is a hard-shell article of luggage. In some embodiments, a hard-shell of the hard-shell article of luggage includes metal. In some embodiments, the hard-shell includes aluminum.

As used herein, “hard shell luggage” refers to luggage that includes at least one hard shell. Each hard shell of the hard shell luggage is sufficiently rigid that it retains a shape that defines an outer surface of the luggage and resists deformation under external loading. For example, other articles of luggage can be stacked on an upper surface of the hard shell luggage or another surface of the hard shell luggage, without transmitting force to internal contents within a compartment of the luggage. In preferred embodiments, the hard shell can be made of metal, such as aluminum. However, it is appreciated that any material typically used in a hard shell as known to one of skill in the art can be used. The term “hard shell” as used herein luggage is used in contrast with soft shell luggage as known to those of skill in the art. For example, soft shell luggage may be made of materials such as fabric nylon, ballistic nylon, and/or other flexible materials. Soft shell luggage articles include main compartments having different closure mechanisms than the hard shell luggage articles of the present disclosure. For example, a soft shell luggage article may include a main compartment having a zipper closure, a button closure, or another similar flexible closure. In contrast, hard shell luggage of the present disclosure includes a compartment that is accessible through a hinged closure that can be held closed by latches. In some embodiments, the hinged closure includes two frame members that are secured together on one side by at least one hinge and secured together on an opposite side by at least one latch.

Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings. It should be understood that the following descriptions are not intended to limit the embodiments to one preferred embodiment. To the contrary, they are intended to cover alternatives, modifications, and equivalents as may be included within the spirit and scope of the described embodiments as disclosed. It is appreciated that any of the features of any of the embodiments can be used with any of the aspects and embodiments and it is understood that they can so be combined in any manner. Nothing herein should be construed to require any feature to be restricted to any combination of features.

As disclosed herein, the expandable frame assembly for hard shell luggage provides various advantages over existing frame assemblies for hard shell luggage. The expandable frame assembly allows a hard shell compartment of hard-shell luggage to be movable between a contracted configuration and an expanded configuration of the hard-shell luggage compartment. The expandable frame assembly also allows two hard shell compartments to be movable with respect to each other between the expanded configuration and the contracted configuration. In the expanded configuration, the hard shell compartment can be secured in a plurality of positions relative to a frame of the expandable frame assembly by one or more bracing mechanisms so that the hard shells are secured in a plurality of positions relative to each other. In some embodiments, the one or more bracing mechanisms enable a user to secure one hard shell in a fixed spatial relation with respect to the frame and both hard shells to be in fixed spatial relation in the plurality of positions relative to each other.

Turning now to FIG. 1, an article of luggage, generally indicated at 10 is illustrated in a contracted condition. The article of luggage includes a first hard shell 12 and a second hard shell 14. The article of luggage 10 is shown in an upright configuration in FIG. 1 in which a tow handle 2 is located at an upper end of the luggage 10 and four wheels 4 are located at a lower end of the luggage. To open the luggage 10, a user can rotate the article of luggage 90 degrees so that the rear face of the first hard shell 12 is on a support surface, such as a floor or a piece of furniture, and the second hard shell 14 is located above the first hard shell 12.

The first hard shell 12 is secured to the second hard shell 14 by a frame assembly indicated generally at 15. The frame assembly 15 includes a first frame member 16, a second frame member 18, and a third frame member 20. The first frame member 16 is secured to the first shell 12. The first frame member 16 extends around the perimeter of the edge of the first shell 12. In some embodiments, the first frame member 16 is secured to the first shell 12 by a plurality of rivets (not illustrated). The second frame member 18 extends about the perimeter of the luggage 10, adjacent to the first frame member 16. The second frame member 18 is secured to the first frame member 16 by a gusset 22 and two sliding bracing mechanisms 70A, 70B, which are described in more detail below. The second frame member 18 may be referred to as a floating frame member, because it may be held in secure adjacent relation against the first frame member 16 when the luggage 10 is in the contracted configuration of FIG. 1 by the bracing mechanisms, or held in an expanded position away from the first frame member 16 by the bracing mechanisms when the article of luggage 10 is in the expanded configuration, as illustrated in FIG. 2A. The third frame member 20 is secured to the second shell 14. The third frame member 20 extends around the perimeter of the open edge of the second shell 14. In FIG. 1, the third frame member 20 is secured to the second shell 14 by a plurality of rivets (not illustrated). The second frame member 18 is secured to the third frame member 18 by two locking closures 25 and by hinges 24.

The second frame member 18 is connected by at least one hinge 24 to the third frame member 20 so that the second frame member and the third frame member define a central opening of the article of luggage. In the embodiment of FIG. 1 and FIGS. 2A, 2B, the second frame member 18 is illustrated as connected by two hinges 24 to the third frame member 20. Each hinge 24 attaches the second frame member 18 to the third frame member 20. According to aspect and embodiments, each hinge 24 does not connect to the first frame member 16. Thus, the second frame member and the third frame member are held in secure engagement with each other by two locking closures 25 and hinges 24. When the locking closures 25 are in an unlocked position, second frame member 18 rotates about the hinge 24 relative to the third frame member 20, the first frame member 16 rotates with the second frame member 18.

In some embodiments, each hinge 24 is secured to the second frame member 18 and the third frame member 20 by rivets.

Each hard shell 12, 14 is made of a material that protects objects within the luggage 10. In some embodiments, the first hard shell 12 and/or the second hard shell 14 comprises metal. In some embodiments, the first hard shell 12 and/or the second hard shell 14 is made of one or more materials comprising aluminum. In some embodiments, the first hard shell 12 and/or the second hard shell 14 is made of one or more materials comprising plastic. In some embodiments, the first hard shell 12 is a rear hard shell of the article of luggage, and the second hard shell 14 is a front hard shell of the article of luggage.

FIG. 2A illustrates the article of luggage with one of the compartments in an expanded condition. The compartment of the article of luggage can be moved between the contracted condition of FIG. 1 and the expanded condition of FIG. 2A by moving the frame member 16 relative to the frame member 18 so as to move second hard shell 14 of the luggage with respect to the frame member 18 and with respect to the first hard shell 12. The frame members 16, 18 are moved with respect to each other to control expansion and contraction of the luggage compartment or opening of the luggage, as described in more detail below.

With reference to FIG. 2B, it is illustrated that the main compartment of the luggage is closed, with the second frame member 18 and the third frame member 20 held in secure engagement with each other by the two locking closures 25 and hinges 24. In FIG. 2B, the locking closures 25 are latches. With this arrangement, the second frame member 18 is engaged with the third frame member 20 to close the compartment and to seal a periphery of the compartment of the luggage in the closed condition.

According to aspects and embodiments, each of the first frame member 16, the second frame member 18, and the third frame member is made of one or more materials used to form the first shell and/or second shell. In some embodiments, each of the first frame member 16, the second frame member 18, and the third frame member is made of one or more materials comprising aluminum. In some embodiments, each of the first frame member 16, the second frame member 18, and the third frame member is made of one or more materials comprising plastic.

According to aspects and embodiments, each of the first frame member 16, the second frame member 18, and the third frame member 20 may be covered in fabric. In some embodiments, the frame members 16, 18, 20 are covered by a woven fabric.

According to aspects and embodiments of the disclosure, a flexible, compressible material may be placed between the first frame member 16, which is attached to the second shell 14 and the second frame member 18. According to aspects and embodiments, in a contracted position of the main compartment, the first frame member of the second shell 14 is adjacent the second frame member 18 so that the first frame member 16 and second frame member 18 are adjacent to compress the compressible material and in an expanded position of the main compartment, the first frame member of the second shell 14 and the second frame member 18 are spaced apart and connected by the compressible material in the expanded position. According to aspects and embodiments, the flexible, compressible material can be attached to the first frame member 16 and the second frame member 18 by any mechanism known to one of skill in the art. For example, according to one embodiment, a first edge 40 of the compressible material can be attached to first frame member 16 and a second edge 60 of the compressible material can be attached to the second frame member 18 by an adhesive.

Referring to FIG. 3, there is illustrated an embodiment of a frame assembly that includes a tongue and groove engagement between the adjacent frame members 16, 18 and 20. The tongue and groove arrangement provides for the frame members firmly engage each other. As illustrated in FIG. 3, the first frame member 16 has a groove 28 and the second frame member 18 has a tongue 26 to provide a mating tongue and groove arrangement between the first and second frame assemblies. In addition, the second frame member 18 includes a tongue 30 and the third frame member 20 includes a groove 32 to also have a mating tongue and groove arrangement between the second frame assembly and the third frame assembly.

In some embodiments, a flexible, compressible material may be placed between the adjacent frame members 16,18 so that the adjacent frame members 16, 18 compress the compressible material when the tongue 26 of one frame member 18 is received in the groove 28 of an adjacent frame member 16. In some embodiments, the compressible material includes a gusset positioned between adjacent frame members. In some embodiments, the compressible material includes a rubber tubing positioned between adjacent frame members.

FIG. 3 also illustrates the flexible material herein also referred to as a gusset, indicated generally at 22, that extends between the first frame member 16 and the second frame member 18. The gusset 22 is made of a flexible material. As noted above, the gusset 22 can be secured to the first frame member 16 and the second frame member 18 by any means known to one of skill in the art, including an adhesive, or other means as disclosed herein, so as to provide a barrier that retains contents in the interior of the main compartment of luggage 10 when the luggage 10 is the expanded configuration, as illustrated in FIGS. 2A, 2B, and 3. The arrows A in FIG. 3 show the direction in which a user has moved the first frame member 16 and the second frame member 18 to position the first frame member 16 and the second frame member 18 in the expanded configuration of FIG. 3.

The gusset 22 is made of a flexible material that allows the first frame member 16 to move with respect to the second frame member 18 as the luggage is moved between the contracted condition and the expanded condition. In some embodiments, the gusset 22 comprises a fabric. In some embodiments, the gusset 22 comprises ballistic nylon. In some embodiments, the gusset 22 comprises polyester. In some embodiments, the gusset 22 is dyed. In some embodiments, the gusset 22 is made of ballistic nylon and/or polyester because those materials facilitate dyeing.

The gusset 22 may be formed as a continuous loop of material that has a first face 36 and a second face 38. When the luggage 10 is in the expanded condition, the first face 36 forms part of the outer surface of the luggage 10 and the second face 38 is oriented inwardly towards contents retained in the luggage 10. The gusset 22 has a first edge 40 that is secured to the first frame member 16 and a second edge 60 that can be secured to the second frame member 18 by any means known to one of skill in the art.

In some embodiments, to prevent the gusset 22 from becoming caught between the first frame member 16 and the second frame member 18, the gusset 22 is a fabric gusset that includes at least one line of stitching that helps the gusset fold inwards into the compartment of the luggage 10. In a preferred embodiment as shown in FIG. 2B, the gusset 22 includes two lines of stitching 46, 48 that extend along the gusset 22. Each line of stitching 46, 48 creates a shape memory in the gusset that encourages the gusset 22 to move inwardly into the compartment of the luggage. Due to the stitching lines of the gusset 22, the gusset 22 is inwardly biased along arrow B so that when the luggage is collapsed, the gusset 22 pulls itself inwardly into the compartment and away from the groove 28 of the first frame member 16 and away from the tongue 26 of the second frame member.

In other embodiments, a single line of stitching can be used instead. In such embodiments, the gusset 22 is stitched into an inwardly oriented V-shape, with the peak of the V-shape located in the compartment of the luggage.

In some embodiments, the gusset 22 includes a stiffener 23 to help hold the material of the gusset cleanly on the inside of the luggage when the luggage 10 is in the collapsed condition. The stiffener may be made of various materials. In some embodiments, the stiffener 23 is made of materials including polyethylene and/or polypropylene.

In some embodiments, to prevent the gusset 22 from becoming caught between the first frame member 16 and the second frame member 18, the gusset 22 includes an elastic member that extends through a central portion of the gusset 22 along the length of the gusset. In some embodiments, the elastic member extends through a channel defined along the length of the gusset. When the luggage 10 is in the expanded condition as shown in FIG. 3, the elastic member would be held in tension such that an inward force along arrow B tends to pull the gusset 22 inward. As a user collapses the luggage 10 from the expanded configuration to the contracted configuration, the inward force along arrow B tends to pull the gusset 22 inward, away from the groove 28 of the first frame member 16 and away from the tongue 26 of the second frame member.

As will be explained further, in some embodiments, the first edge 40 of gusset 22 is secured to a first rod 50 that is secured to the first frame member 16 and the second edge 60 of the gusset 22 is secured to a second rod 62 that is secured to the second frame member 18. In some embodiments, each edge of the gusset is wrapped around a respective rod 50, 62. In some embodiments, each edge of the fabric is held onto a respective rod by a friction fit with a c-shaped holder or insert 56, 66. The c-shaped holder or insert has a c-shaped cross section. The c-shaped holder or insert is secured by a friction fit in a recess 54, 64 in a respective frame member.

FIGS. 4A-4D illustrate steps in securing an edge 40 of the gusset 22 in the frame member 16 to arrive at the assembled structure of FIG. 3. FIG. 3 illustrates both edges 40, 60 of the gusset 22 secured to a respective frame member. FIG. 4A illustrates a rod 50 that is used for securing a first edge 40 of the gusset 22 to the first frame member 16. Referring to FIG. 4B, edge 40 of the gusset 22 is at least partially wrapped around a respective rod 50. In some embodiments, a first edge 40 of the gusset 22 is folded over first rod 50 and is secured in a first recess 54 in the first frame member 16, as illustrated in FIG. 4D. To frictionally secure the first rod 50 and the first edge 40 of the gusset 22 in the first recess 54, the first rod 50 and the gusset 22 are received in at least one first insert 56 as illustrated in FIG. 4C, that is received in the first recess 54 as illustrated in FIG. 4D. As illustrated in FIG. 4C, the first insert 56 has a c-shaped channel that receives the first rod 50 and edge 40 of the gusset 22 and applies pressure to the gusset 22 wrapped around the first rod 50.

Referring again to FIG. 3, a second edge 60 of the gusset 22 is folded over second rod 62 and is secured in a second recess 64 in the second frame member 18. To frictionally secure the second rod 62 and the gusset 22 in the second recess 64, the second rod 62 and the gusset 22 are received in at least one second insert 66 that is received in the second recess 64 of the frame member 18. Insert 66 has a c-shaped channel that receives the second rod 62 and gusset 22 and applies pressure to the gusset around the second rod 62. With this arrangement of the gusset, the rods, c-shaped inserts, and the recesses in the frames, the edges of the gusset 22 can be secured to the respective frame members 16, 18 so as to provide the sealed compartment having the expansion condition and contraction condition of the frames 16 and 18 and the shells 12, 14 with respect to each other.

In some embodiments, the first rod 50 includes at least four elongate rod segments, and the recess 54 is defined within four longitudinal portions of the first frame member 16. Each elongate rod segment of the first rod 50 is received in the recess 54 in a respective longitudinal portion of the first frame member 16. FIG. 4E shows four first rod segments 50A, 50B, 50C, 50D, which can each be received in a length of the recess 54 in a longitudinal portion of the first frame member 16 to secure the gusset 22 to the first frame member 16.

In some embodiments, the second rod 62 includes at least four elongate rod segments, and the recess 64 is defined within four longitudinal portions of the second frame member 18. Each elongate rod segment of the second rod 62 is received in the recess 64 in a respective longitudinal portion of the second frame member 18. FIG. 4E shows four first rod segments 62A, 62B, 62C, 62D, which can each be received in a length of the recess 64 in a longitudinal portion of the second frame member 18 to secure the gusset 22 to the first frame member 18.

In some embodiments of framing assemblies according to the present disclosure, the c-shaped insert member is not included. For example, in some embodiments, at least one edge of the gusset is folded over a respective rod, and the rod is received in a respective recess defined in a respective frame member without the c-shaped member. In some embodiments, each edge of the gusset is folded over a respective rod, and each rod is received in a respective recess defined in a respective frame member. Another example of an embodiment of a framing assembly is shown in FIG. 10. In some embodiments, the frame assembly includes two frame members instead of the three frame members as shown for example in the embodiment of FIG. 1. For example, in some embodiments, the first frame member 16 of the embodiment of FIG. 1 is omitted, and the gusset is secured directly to the first shell.

FIG. 10 shows a cross-sectional view of a portion of an embodiment of an article of luggage 110 that includes a frame assembly having two frame members. In the embodiment of FIG. 10, the article of luggage 110 includes a first hard shell 112 and a second hard shell 114.

The first frame member 118 is secured to the first hard shell 112 by a gusset 122 and two sliding locks. The sliding locks are similar to the sliding locks discussed herein in relation to other embodiments. The first frame member 118 may be referred to as a floating frame member, because it may be held in secure adjacent relation against the first shell 112 when the luggage 110 is in a contracted configuration, or held in an expanded position away from the first shell 112 when the article of luggage 110 is in an expanded configuration. The second frame member 120 is secured to the second shell 114. The second frame member 120 extends around the perimeter of the open edge of the second shell 114. In FIG. 10, the second frame member 120 is secured to the second shell 114 by a plurality of rivets (not illustrated).

The two frame members 118, 120 of the frame assembly 115 of FIG. 10 are referred to here as the first frame member 118 and the second frame member 120. The first frame member 118 serves similar purposes as the second frame member 20 in the above frame assembly 15 described above, and the second frame member 120 serves similar purposes as the third frame member 20 in the frame assembly 15 described above.

The gusset 122 may be formed as a continuous loop of material that has a first face 136 and a second face 138. When the luggage 110 is in the expanded condition, the first face 136 forms part of the outer surface of the luggage 110 and the second face 138 is oriented inwardly towards contents retained in the luggage 110. The gusset 122 has a first edge 140 that is secured to the first shell 112 and a second edge 142 that is secured to the first frame member 118. In some embodiments, the first edge 140 of the gusset is secured directly to the first shell 112 by a fastener and the second edge 142 of the gusset is secured directly to the first frame member 118 by a fastener. In some embodiments, the first edge 140 of the gusset is secured directly to the first shell 112 by an adhesive and the second edge 142 of the gusset is secured directly to the first frame member 118 by an adhesive.

The first frame member 118 is connected by at least one hinge to the second frame member 120 so that the first frame member and the second frame member define a central opening of the article of luggage 110. For example, in some embodiments the first frame member 118 is connected by two hinges to the second frame member 120.

According to aspects and embodiments, multiple rods may be used to secure the gusset 22 to a respective one of the frame members. For example, four rods may be used to secure the gusset to a respective one of the frame members, with each rod securing an edge of the gusset to one of four longitudinal regions of the respective frame member.

According to aspects and embodiments, the c-shaped insert is made of a material that is sufficiently rigid to retain the gusset and the rod in the recess, and is sufficiently resilient that it can be held in compression in the channel to provide a friction fit of the rods and gusset in the respective recess. In some embodiments, the c-shaped insert is made of plastic.

Referring generally to FIGS. 5-6, at least one bracing mechanism 70A, 70B is provided to allow a user to move the shell 14 of the article of luggage 10 between the contracted condition and the expanded condition of the article of luggage 10 and to secure the shell 14 in a plurality of positions.

FIG. 7 shows the article of luggage 10 when the main compartment is opened via the hinges 24. The main compartment includes a liner 84 that is secured to the first frame member 16. The article of luggage includes a first bracing mechanism 70A at one side of the main compartment and a second bracing mechanism 70B at an opposite side of the main compartment. In some embodiments, the bracing mechanisms are sliding locks. U.S. Pat. No. 8,479,900 discloses a bracket assembly for mounting to a piece of expandable luggage. U.S. Pat. No. 8,479,900 is incorporated herein by reference in its entirety. In some embodiments of a frame assembly and/or luggage according to the present disclosure, one or more of the bracing mechanisms is a bracket assembly that is disclosed in U.S. Pat. No. 8,479,900.

Each bracing mechanism 70A, 70B includes a tongue portion 72 that is received in a slot 74 defined in a base 76. Movement of the tongue 72 with respect to the base 76 is controlled by at least one spring biased latch 78. Each latch 78 is fixed to a respective base. Each latch 78 has a latching surface 82 that is configured to engage one of a plurality of openings 80 defined in the tongue 72. When the luggage 10 is in a contracted condition as illustrated in for example FIG. 7, the spring bias of the latch 78 causes the latching surface 82 to engage a first one of a plurality of openings 80 defined in the tongue. When the luggage 10 is in an expanded condition as illustrated in for example FIG. 5-6, the spring bias of the latch 78 causes the latching surface 82 to engage one of at least one of a second plurality of openings 80 defined in the tongue. With this arrangement, the first frame member 16 is movably secured to the second frame member 18 by at least one bracing mechanism 70A, 70B that in a first position holds the second frame member in secure engagement against the first frame member such that the second frame member is adjacent the first frame member, and in a second position secures the second frame member in spaced apart relation with respect to the first frame member.

According to at least one embodiment as illustrated for example in FIG. 5-6, the base 76 is secured to the first frame member 16 and the tongue 72 is secured to the second frame member 18. According to one embodiment, as illustrated in FIG. 7, the bracing mechanisms are secured to the frame members 16, 18 inside the hard-shell luggage compartments 12, 14 so that each latch is accessible from the inside of the luggage 10. Referring to FIGS. 7-9, there is illustrated movement of the luggage from the contracted condition to the expanded condition. When a user wishes to transition the luggage 10 from the contracted condition as illustrated in FIG. 7 to the expanded condition as illustrated in FIG. 9, the user rotates the latch 78 to disengage the first opening as illustrated in FIG. 8. Then the user pulls a strap 84 to slide the second frame member 18 with respect to the first frame member 16. The spring bias of the latch 78 causes the latching surface 82 to engage a second opening 80 defined in the tongue (See FIG. 6). It is appreciated that the tongue 72 can have plurality of openings 80 to provide for a plurality of expanded positions. To move the luggage back to the contracted condition, the user rotates the latch 78 to disengage the second opening in the tongue and the user slides the tongue 72 with respect to the base 76 to cause the second frame member 18 to be in direct engagement with and adjacent the first frame member 16. According to an aspect of the present disclosure, a frame assembly may include the first frame member, the second frame member, the gusset, the rods, the inserts, and the recesses in the respective frame members, and one or more sliding locks as described herein, without the first and second shells. The frame assembly may be subsequently used to form part of a hard shell luggage. According to an aspect of the disclosure, the frame assembly can be used to form part of an expandable and contractable soft shell article of luggage. According to aspects of the disclosure, the frame assembly can be used with various types, sizes and arrangement of luggage assemblies including, for example, carry on sized articles of luggage, luggage that is sized to be checked (not carried on), wheeled duffels, and various other size, arrangements and materials for the shells.

Advantages of an expandable and contractable hard shell luggage article of the present disclosure include the ability to expand a compartment of the hard shell luggage article to accommodate additional or larger items and to contract the compartment of the hard shell luggage article to be smaller in size. Another advantage is that the contractable hard shell luggage protects items contained within the luggage while in a contracted position and also while in an expanded condition. In addition, sliding locks secured to an expandable frame assembly of the hard shell luggage enable the expandable frame assembly of the hard shell luggage to provide stable support of the article of luggage. In addition, the expandable frame assembly provides stable support for additional items of luggage or other items that may be placed on an upper surface of the article of luggage, such as when a user is moving the luggage along a walkway.

Another advantage of the expandable frame assembly of the article of luggage is that the expandable hard-shell compartment of the hard shell luggage remains sealed in both the expanded position and the contracted position. In particular, the hard-shell compartment is sealed by a gusset. The gusset is secured about its perimeter to the frame of the luggage so that the gusset forms a barrier that seals the expandable hard-shell compartment of the luggage. The gusset is made of a flexible material that allows the gusset to be positioned within the main compartment of the luggage when the luggage is in a contracted condition and that allows the gusset to form a portion of an external surface of the luggage when the luggage is in an expanded condition.
