Description

Technical Field

[0001] This utility model generally relates to suitcases, and more particularly to suitcases having a closing component, and even more particularly to installing and attaching the closing component to a suitcase. Background Technology

[0002] Existing suitcases typically include zippers or other closure components to selectively connect the two shells of the suitcase. Attaching the closure component to the shell usually requires a technician to properly align the closure component and the shell, and often involves manually attaching the closure component, for example, by sewing. Therefore, attaching the closure component to the suitcase is often a time- and costly aspect of suitcase manufacturing.

[0003] Therefore, a more cost-effective solution is needed for attaching the closure component to the suitcase. Utility Model Content

[0004] In one example of this disclosure, a suitcase is disclosed. The suitcase includes at least one housing defining an edge, a zipper strap, a joining structure selectively connecting the zipper strap and the housing, the joining structure including an integrally formed track defining a gap, and a retaining feature selectively received in the gap and extending from the gap in a direction transverse to the track, wherein one of the housing or the zipper strap includes the integrally formed track, and the other of the housing or the zipper strap includes the retaining feature.

[0005] In some examples of the luggage, the selective connection of the rails and retaining features helps align the closing components and the housing during assembly.

[0006] In some examples of the suitcase, the closing component is selectively removable from the housing.

[0007] In some examples of the suitcase, the housing includes the retaining feature integrally formed along a portion of the edge, and the zipper strap includes the integrally formed track along a portion of the edge of the zipper strap, wherein the track defines the gap to receive the retaining feature.

[0008] In some examples of the suitcase, a portion of the housing is received internally by the zipper strap.

[0009] In some examples of the suitcase, the housing includes the integrally formed track extending along a portion of the edge of the housing, and the zipper strap includes the retaining feature extending along a portion of the edge of the zipper strap.

[0037] In some examples of the luggage, the support member defines a connection between the shell and the second flange.

[0038] In some examples of the luggage, the at least one support member has a thin fin-like shape.

[0039] In some examples of the luggage, a guide flange (1327) is formed on a portion of the at least one support member defining the cutout.

[0040] In some examples of the luggage, the shell includes a support flange extending from the shell and spaced apart from the track, and the at least one support member extends between the flange and the support flange.

[0041] In some examples of the luggage, the support flange defines a connection between the shell and the second flange.

[0042] In some examples of the luggage, the at least one support member is spaced apart from the first flange and the second flange adjacent the gap to define a cutout to accommodate the lug in the track.

[0043] In some examples of the luggage, the track includes a plurality of support members positioned at discrete locations along the rim.

[0044] In some examples of the luggage, the track includes a plurality of support members including the at least one support member, and the plurality of support members are positioned at discrete locations along the rim.

[0045] In some examples of the luggage, the cutout in each of the plurality of support members at least partially aligns to form a channel to accommodate the retention feature.

[0046] In some examples of the luggage, the track includes a plurality of support members including the at least one support member, the plurality of support members include a plurality of cutouts including the cutout, and the plurality of cutouts of each of the plurality of support members at least partially align to form a channel to accommodate the retention feature.

[0047] In some examples of the luggage, the luggage further includes two or more shells, the two or more shells including at least one shell and a hinge connecting the two or more shells.

[0048] In some examples of the luggage, the at least one shell includes a first shell and a second shell, and the luggage includes a hinge coupling the first shell and the second shell.

[0049] In some examples of the luggage, the hinge includes integrally molded bosses formed along respective sides of the first and second shells to interleave together, and a rod extending through the holes to form a hinge pin, each of the bosses defining a hole.

[0094] The present application can disclose luggage having a track to engage a closure assembly. The luggage can include a main body having two or more shells hingedly attached. Each shell can define a track extending along at least a portion of a perimeter of each shell. A closure assembly can be attached to the perimeter of each shell and allow selective access to an interior volume of the luggage. The closure assembly can be removably attached to the track on each shell. The closure assembly can include two zipper tapes, each zipper tape including zipper teeth on a first edge and a retention feature on a second edge. The zipper teeth on each zipper tape can join to link the zipper tapes together to form the closure assembly. The retention feature of each zipper tape can be attached to or removed from the corresponding track on each shell. Thus, the closure assembly can be simply installed on or removed from each shell. In some examples, the shells can include the retention features and each zipper tape can include the track. Additionally, the closure assembly can be removed from the shells and replaced when damaged, rather than replacing the entire luggage. Each shell, or the two or more shells together, can define an entry area or entry opening for attaching or removing the closure assembly, or one or both zipper tapes, to or from the track. For example, the entry area can be positioned near an end of the track.

[0095] In some examples, the shells can be coupled together by a hinge portion. For example, the hinge portion can include a plurality of integrally molded bosses formed along a portion of the perimeter of the shell. The bosses of each luggage shell can interengage with one another to receive a hinge pin to form a hinge structure and pivotally connect the shells together. In another example, the hinge portion can be a discrete feature coupled to or positioned along a portion of the perimeter of the shell. Discretely positioned hinge portions can help secure the zipper tape to the shell or track. In one example, the interengaging bosses can be referred to and include staggered or interleaved bosses herein.

[0096] Figure 1A A right front isometric view of an example luggage 100 in a closed configuration is shown. Figure 1B A left rear isometric view of an example luggage 100 is shown. The luggage 100 can alternatively be referred to as a luggage article, bag, cart, etc. In one example, the luggage 100 can be an upright hard-sided luggage, such as a spinner luggage. In other examples, the luggage article 100 can be many types of luggage, including soft-sided spinner luggage with a molded frame or inner shell, hybrid spinner luggage, a container, etc. The luggage 100 can have a main body 102 with a plurality of panels that define an interior storage volume to carry an article of a user.

[0097] The luggage 100 can include a front panel 104 and an opposing rear panel 106, a top panel 112 and a bottom panel 114, and opposing left and right panels 108 and 110. Each panel can have an outer surface 138 and an inner surface 136 that together define an interior storage volume 130. The luggage 100 can move between a closed configuration and an open configuration to provide access to the interior storage volume 130, in which the rims or perimeters 134 of the two or more shells 118, 120 of the main body 102 are positioned adjacent to one another. The luggage 100 can be selectively opened or closed by a closure assembly 180. The closure assembly 180 can define a connection line 122 between the two or more shells 118, 120. The two or more shells 118, 120 can include a first shell 118, which can be referred to as a top shell or lid, and a second shell 120, which can be referred to as a bottom shell or base shell. Reference can be made to either the first shell 118 or the second shell 120, but it should be understood that either shell can include the same or similar features.

[0098] The shells 118, 120 can be joined along one of the panels (e.g., the left panel 108) by a hinge 170. In one example, portions of the hinge 170 can be integrally formed with the shells 118, 120. In some examples, the hinge 170 can be separately formed and attached to or integrally formed with the shells 118, 120. Each shell 118, 120 can be made entirely or partially from an injection molded polymer. Each shell 118, 120 can form a single unit having at least some of the features of the shells described herein formed by injection molding. For example, the hard-sided luggage 100, such as shown in FIGS. 1-6, can be formed at least partially by an injection molding process. The soft-sided luggage 100 can be made by injection molding all or portions of the perimeter portions of each shell 118, 120 and attaching the soft-sided exterior portions and desired frame members thereto. Exterior or additional features can be attached to the molded portions of the luggage 100.

[0099] In some examples, the luggage article 100 can include one or more carry handles 128 and / or a retractable tow handle 126 that can extend from a recess or recessed portion of the rear panel 106 of the luggage article 100. The retractable tow handle 126 can extend outwardly from the recess and retract into the recess and can allow a user to pull or tow the luggage article 100. The luggage article 100 can include one or more foot elements 148, such as wheels, casters, spinner assemblies, posts, or the like, to support or enable the luggage article 100 to move on a support surface, such as a floor, street, sidewalk, or ground.

[0100] The luggage 100 can include a hinge 170 positioned along a panel of the luggage 100. The hinge 170 of the luggage 100 can be defined by bosses 172 that are spaced apart and positioned along a portion of the perimeter 132 of each shell 118, 120. In one example, the bosses 172 are integrally molded with the shells 118, 120. When the shells 118, 120 are positioned together, the bosses 172 of each shell 118, 120 are interleaved together. Each boss 172 includes a hole 174 formed therethrough, and when interleaved together, the holes 174 are aligned. The bosses 172 on one shell 118, 120 can be pivotally coupled together with the bosses 172 on the other shell 118, 120 by a rod or pin positioned through the bosses 172 by being received in the aligned holes 174 to form a hinge pin. The hinge 170 can be continuous or discontinuous (e.g., defined by multiple sub-hinges). Thus, the hinge 170 can be secured by a single rod or pin or multiple rods or pins forming multiple hinge pins. The rod can be removable and replaceable when damaged or to pivotally attach different shells 118, 120 together.

[0101] Reference Figure 2Each shell 118 can define an engagement structure 199 that includes a track 190 and a closure assembly 180 that includes a corresponding retention feature. For example, the track 190 can attach the closure assembly 180 to the shell. In one example, the closure assembly 180 is a zipper assembly. The track 190 can be an integrally molded feature of each shell 118. In some examples, the track 190 can be separately formed and attached to the luggage shell 118, 120, or defined by the closure assembly 180. For example, the track 190 can be a separate feature or portion of a frame coupled to the luggage shell 118, 120. The track 190 can be formed at or near the peripheral edge or rim 134 of each shell 118. The track 190 can be continuous or discontinuous. For example, the track 190 can be segmented or positioned along discrete portions of the shell 118, or have different heights, widths, or thicknesses along portions of the shell 118. The track 190 can be formed on the interior of the shell 118 or on the exterior of the shell 118. The closure assembly 180 can selectively engage with the track 190 to define the engagement structure 199. In some examples, the closure assembly 180 can be removable from the track 190.

[0102] In some examples, during installation, the two shells 118, 120 can be aligned and the closure assembly 180 can be engaged with the tracks 190 of the two shells 118, 120. In other examples, the zipper assembly 180 can include a first zipper tape 182A and a second zipper tape 182B. The zipper tapes 182A, 182B can define retention features. The retention features of the first zipper tape 182A of the closure assembly 180 can individually engage the first track 190A of the first shell 118, and the second zipper tape 182B in the closure assembly 180 can engage the second track 190B of the second shell 120. After installation, the first zipper tape 182A can then selectively engage the second zipper tape 182B to form the closure assembly 180. While the description is given with respect to the track 190 being defined by the shell 188, in some examples, the closure assembly 180 can define the track 190. Similarly, the retention features can be defined by the shells 118, 120. Thus, in some examples, the shells 118, 120 can define the retention features and the zipper assembly 180 can define one or more tracks 190, and the track 190 of the closure assembly 180 can receive the retention feature of the shell 118 or 120.

[0103] The closure assembly 180 can be received onto the track 190 at a defined location of the track 190, such as at an entry region 194 of the track 190. In one example, the entry region 194 can be an opening formed in the housing 118 that allows access to the track 190. In one example, the entry region 194 is an example of a discontinuous track 300, and can include an opening in the track formed by end portions of the track 300 or the housing 118, 120 spaced apart by a break (e.g., 3-6 centimeters). The entry region 194 can be positioned at or near an end portion of the track 190, such as near or adjacent to an end of the hinge structure 170. In some examples, the entry region 194 can define a beginning or end of the track 190. The entry region 194 can be defined by the housing 118 or the housing 118, 120. The entry region 194 can be an opening defined between two spaced apart portions of an exterior side of the track 190 or an exterior 138 of the housing 118, 120. For example, the entry region 194 allows access to the track 190 from the exterior 138 of the housing 118, which the track 190 is formed on. In some examples, the entry region 194 can be positioned at the interior 136 of the housing. For example, the entry region 194 can define an opening formed in the housing 118 or between two interior portions of the track 190 to allow access to the track 190. For example, the entry region 194 can be defined between two end portions of the track 190 spaced apart along the interior 136 of the housing 118. The closure assembly 180 can be flexible to follow the path of the track 190 around at least a portion of the perimeter 134 of the luggage housing 118 or the housing 118, 120 when attached to the track 190.

[0104] In some examples, the track 190 can slidably engage or receive the closure assembly 180 to define an engagement structure 199. In one example, the track 190 and the closure assembly 180 can allow for more efficient assembly by eliminating the need for additional attachment mechanisms (such as stitching, welding, adhesive, or other additional steps) to engage the closure assembly 180 to the housing 118. The track 190 and the closure assembly 180 can also reduce the need for a technician to properly align the closure assembly 180 along a portion of the housing 118. In another example, when the closure assembly 190 is damaged, or when a user prefers a closure assembly 180 with different features or aesthetics (such as waterproofing, color, texture), the closure assembly 180 can be removed in a similar manner as it was installed and replaced with a different assembly.

[0105] Referring to FIGS. 3-5B, an example of a closure assembly 200 and a track 300 is shown. The closure assembly 200 and the track 300 can have similar or identical features or functionality as the closure assembly 180 and the track 190 described above. For example, the closure assembly 200 can define a retention feature 216. The housings 118, 120 can include the track 300. The closure assembly 200 of this example can be an attachable closure assembly 200 that slides into or is slidably received in the track 300 to define an engagement structure 400. For example, the track 300 can internally receive a feature of the closure assembly 200. The track 300 can be spaced apart from the perimeter 134 of the housing 118 and positioned interior to the housing 118. In some examples, each track 300 can define a gap 330 and slidably receive a feature of the closure assembly 200 in the gap 330. As described above, in some examples, the housings 118, 120 can define or include integrally formed retention features 216 and the closure assembly 200 can define one or more tracks 300 and the tracks 300 of the closure assembly 200 can receive the retention features of the housings 118 or 120 to define the engagement structure 400. Thus, in some examples, the closure assembly 200 can include a track 300 that internally receives a retention feature 216 of the housing 118.

[0106] In Figures 3A-3BIn some examples, an example closure assembly 300 is shown. The closure assembly 300 can also be referred to as a slide-in closure assembly 300. The closure assembly 330 can include two zipper strips 202A, 202B that are selectively engageable along the connection line 122. Each zipper strip 202 can include interengaging features 206 (e.g., zipper teeth or zipper coils) and one or more retention features 216. The interengaging features 206 can connect the zipper strips 202A and 202B. The interengaging features 206 can extend along at least a portion of the length of the inner edge 232 of the zipper strip 202. The retention features 216 can engage the track 300 or prevent the zipper strip 202 from being removed from the track 300. The retention features 216 can extend along at least a portion of the length of the outer edge 230 of the zipper strip 202. The retention features 216 can be continuous. For example, the retention features 216 can extend along the length of a portion of the outer edge 230. In other examples, the retention features 216 can be segmented or discontinuous. For example, the retention features 216 can include separate portions that are spaced apart along the outer edge 230 or can extend different widths from the outer edge 230. The retention features 216 can be defined as or include lugs 218. The optional retention features 216 can include ribs 220 that extend along at least a portion of the length of the zipper strip 202 and are spaced apart from the lugs 218 toward the inner edge 232. The optional ribs 220 can be continuous or discontinuous. A neck 222 can be defined by the zipper strip 202 adjacent to the lugs 218. When the optional ribs 220 are present, the neck 222 can be defined between the ribs 220 and the lugs 218.

[0107] As Figure 5AAs shown, the retention feature 216 of the zipper tape 202 is received in the track 300, the zipper tape 202 is moved in a direction parallel to the track 300 with the neck 222 passing along a gap 330 formed by the track 300 (e.g., by opposing walls or flanges 306, 308). The lug 218 can have a width dimension XI. In one example, the width dimension can be between 10 and 15 millimeters. The width dimension XI of the lug 218 can be greater than the gap 330, inhibiting or preventing the zipper tape 202 from moving from the track 300. For example, the width dimension XI prevents the zipper tape 202 from being removed through the gap 330 in a direction 340 toward the interengagement feature 206. This lug structure 218 also allows the zipper tape 202 to be moved along the track 300 in a direction of the gap 330 (e.g., by sliding). An optional rib 220 can be positioned on the zipper tape 202 at an end of the neck 222 opposite the lug 218. The rib 220 (if present) inhibits or prevents the zipper tape 202 from moving from the track 300 (e.g., from the gap 330) in a direction away from the interengagement feature 206. This rib structure 220 also allows the zipper tape 202 to be moved along the track 300 in a direction of the track 300 (e.g., by sliding). The lug 218 can extend away from one or both sides of the zipper tape 202. The rib 220 (if present) can extend away from one or both sides of the zipper tape 202.

[0108] In one example, the zipper tape 202 can include an elongated zipper string 204 positioned on or attached to an inner edge 240 of an extrusion 208 along an outer edge 234. The extrusion 208 can be or define the retention feature 216. In one example, the zipper string 204 can be formed of a woven material. In one example, the extrusion 208 can be made of a plastic material and, in one example, formed by an extrusion process. As Figure 3A and Figure 3B As shown, the zipper string 204 can be connected or attached to the extrusion 208 by a stitch 212. In some examples, the zipper string 204 can be connected or attached to the extrusion 208 during extrusion or molding of the extrusion (e.g., overmolding). In some examples, the zipper string 204 can be attached to the extrusion 208 by an adhesive or fastener. In this example, the interengagement feature 206 can be positioned along an inner edge 232 of the zipper string 204.

[0109] The lugs 218 can extend along an outer edge 230 of the extrusion 208. As described above, optional ribs 220 can extend along the extrusion 208 spaced apart from the lugs 218. The necks 222 can be defined by the extrusion 208 adjacent to or spaced apart from the lugs 218. In the presence of ribs 220, the necks 222 can be defined by the extrusion 208 between the lugs 218 and the ribs 220. This lug structure 218 also allows the zipper tape 202 to move along the track 300 in the direction of the track 300 (e.g., by sliding). In this example, the lugs 218 can extend away from one or both sides of the extrusion 208. In the presence of ribs 220, the ribs 220 can extend away from one or both sides of the extrusion 208. In another example, the zipper tape 202 can be made entirely of the zipper strip 204, with the interengaging features 206 and the retention features 216 (e.g., lugs 218, necks 222, optional ribs 220) attached to the zipper strip 204 and positioned in the examples described above. In another example, the zipper tape 202 can be made entirely of the extrusion 208, with the interengaging features 206 and the retention features 216 (e.g., lugs 218, necks 222, optional ribs 220) attached to the extrusion 208 and positioned in the examples described above.

[0110] The interengaging features 206 (e.g., zipper teeth 210) can be selectively brought together along the connection line 122 (e.g., by the zipper slider 224) to form the closure assembly 200. The closure assembly 200 can be oriented to have an outer side 250 configured to be visible from the exterior of the luggage 100 and an inner side 252 configured to face the interior volume of the luggage 100. The zipper slider 224 can be positioned on the outer side 250.

[0111] In one example, each zipper tape 202 can be individually installed on the track 300 on the respective housing 118, 120 to define the respective engagement structure 400. In another example, each zipper tape 202 can be individually removed from the respective housing 118, 120. In another example, replacement zipper tapes 202 can be individually installed on the track 300 on the respective housing 118, 120 to replace the zipper tapes 202 removed from the respective housing 118, 120. This can allow a user to replace only a portion of the closure assembly 200, or to combine different zipper tapes 202 with desired features, or to achieve a desired aesthetic (e.g., color or texture). The closure assembly 200 can also be flexible to aid in removing or installing the closure assembly 200 into the track 300.

[0112] With continued reference to Figure 3A and 3BIn one example, the width dimension X1 is about 10 to 15 millimeters. The width dimension X1 can be greater than a width dimension X2 of the neck 222. In one example, the width dimension X2 is about 5 to 10 millimeters. In one example, the lug 218 can have a generally T-shape. The lug 218 can extend toward either or both of the inboard side 252 and the outboard side 250. Each of the pointed sides of the lug 218 can be referred to as first and second lugs, collectively as lugs, or together as a single lug. The lug 218 can have an outer surface that defines a rounded outer profile. The lug 218 can have an inner surface that, in one example, can extend at a right angle from the zipper tape 202. In other examples, the lug can define various geometric shapes or shapes (e.g., rectangular, triangular, etc.). The rib 220 can have a width dimension X3 that is greater than a surrounding portion of the zipper tape 202. In some examples, the width dimension X2 of the rib 220 can be less than the width dimension X1 of the lug 218. In one example, the width dimension X3 is about 5 to 15 millimeters. The rib 220 can also have various profiles and shapes.

[0113] Referring to Figure 2 Turning to Figure 4A and 4B , the track 300 is shown as being formed on the perimeter 134 of the luggage shell 118. As described above, the track 300 can receive and retain the closure assembly 200. The track 300 can extend along all or a portion of the perimeter 134 of the luggage shell 118 and be positioned on the inboard side 136 of the rim 132. The track 300, or portions of the track 300, can be continuous. In other examples, the track 300 can be discontinuous. For example, the track 300 can include separately defined and spaced portions, or the track 300 can have different heights or thicknesses along portions of the shell 118. The track 300 can be spaced apart or adjacent to the rim 132. The track 300 can include a first portion 306 and a second portion 308.

[0114] The track 300 can be integrally formed or molded with the shell 118. For example, the track 300 can be formed along the inner side 136 of the rim 132 by injection molding. The track 300 can also serve as a structural support or reinforcement of the luggage shell 118 (e.g., along the perimeter 134). In some examples, the track 300 can be separately formed or attached to the shell 118. For example, the track 300 can be a separate component or portion of a frame that is attached or mounted to the shell 118. For example, the track 300 can be attached to the shell 118 by fasteners (e.g., rivets or screws, etc.). The track 300 can be made of a molded material (e.g., polymer or plastic) or metal (e.g., aluminum). In some examples, the track 300 can be attached to the shell 118 by respective attachment features (e.g., holes defined in the track 300 or the shell 118) to receive a post or snap feature of the other. In some examples, the track 300 can be attached to the shell 118 by stitching or plastic welding.

[0115] The first portion 306 can define a first wall or flange 306 having an inner surface 310, an outer surface 312, and an end surface 314. The first flange 306 can extend from the inner surface 136 of the shell 118. In one example, the first flange 306 can extend away from the shell 118 at a right angle. The first flange 306 can be continuous or discontinuous.

[0116] The second portion 308 can be positioned adjacent to and aligned with the first portion 306. The second portion 308 can be a second wall or flange 308 having an inner surface 316, an outer surface 318, and an end surface 320. The second flange 308 can extend from the shell 118. For example, the second flange 308 can be coupled to the shell 118 (e.g., extend indirectly from the shell 118) or directly extend from the shell 118. The second flange 308 can be continuous or discontinuous. The second flange 308 can also include an inner rim 322 extending from the outer surface 320 of the second flange 308.

[0117] A gap 330 can be formed between the first portion 306 and the second portion 308. In one example, the gap 330 is formed between the end surface 314 of the first flange 306 and the end surface 320 of the second flange 308. The gap 330 can be continuous through the track 300. The gap 330 can receive and hold the zipper tape 202. The gap 330 can have a gap width dimension X4. In one example, the gap width dimension X4 can be between 5 millimeters and 10 millimeters. The inner rim 322 can help align the zipper tape 202 in the track 300. The inner rim 322 can also protect the zipper tape 202 from contents in the interior volume of the luggage 100.

[0118] The second portion 308 can be connected to the shell 118 by one or more support members 326 extending from the interior surface 136 of the shell 118. The support members 326 can extend from the shell 118 and support the second flange 308. The support members 326 can position the second portion 308 away from the first portion 306 to define the gap 330. The support members 326 can be walls or fins extending from the shell 118. The support members 326 can be oriented orthogonally or perpendicularly to the second flange 308. The support members 326 can be relatively thin or elongated members. In one example, the support members 326 can engage the interior surface 310 of the first flange 306 and / or the interior surface 136 of the shell 118 and can provide some structural support for the first flange 306, where present.

[0119] In the illustrated example, the track 300 can include a plurality of support members 326 spaced along the length of the track 300. The support members 326 together and / or each support member 326 can define a cutout 328 oriented with the track 300. For example, each support member 326 can define a cutout 328 adjacent and around the gap 330, the cutout 328 sized to allow the lug 218 of the zipper tape 202 to extend through the gap 330, the lug 218 on the interior surface 310, 316 of at least one of the first flange 306 and the second flange 308, as illustrated. The shape of the cutout 328 can match the shape of the portion of the zipper tape 202. In some examples, the track 300 includes a plurality of support members 326 having a plurality of cutouts 328 defining a channel 328. The cutouts 328 can be aligned at least partially along a portion of the track 300 to define the channel 328. In other examples, the support members 326 can be relatively wider continuous features and extend along at least a portion of the track 300. The cutouts 328 can be formed in the wider or continuous support 326, defining the channel 328 to receive one or more lugs 218. Alternatively, the channel 328 can be shaped to have a primary dimension that can be greater than the width dimension XI of the zipper tape 202. Figure 5A

[0120] An optional support flange 332 can extend from the interior surface 136 of the shell 118. The support flange 332 can engage a portion of the one or more supports 326 to provide a support structure. For example, the one or more support members 326 can extend between the shell 118 and the support flange 332. In some examples, the support members 326 can extend between the support flange 332 and the second flange 308. The support flange 332 can extend along at least a portion of the interior surface 136 of the shell 118 and along at least a portion of the track 300. The support flange 332 can also serve as a point of engagement for a liner or other feature of the luggage 100 to attach to the shell 118.

[0121] ​Figure 5A An example of a joint structure 400 including a closure assembly 200 held along opposing edges by tracks 300 formed on each of the housings 118, 120 is shown, as Figure 5B illustrated. Figure 5B is Figure 5A an enlarged view of the joint structure 400 and illustrates a single zipper tape 202 positioned in the track 300. When positioned in the track 300, the neck 222 can extend through the gap 330, the lug 218 positioned on and / or against the inner surfaces 310, 316 of the first and second flanges 306, 308. The neck 222 can be configured to engage or mate with the gap 330 defined between the end surfaces 314, 320 of the first and second flanges 306, 308. The lug 218 can be received in the channel 328 formed by the bracket 326. Because the lug 218 is sized larger than the gap 330, the zipper tape 202 can be retained in the track 300, and thus the zipper tape 202 can not be pulled out in a direction extending transverse to the gap 330, as Figure 5A and 5B indicated by the arrow 340. The width dimension XI of the lug 218 can be less than the width dimension of the channel 328 to allow the lug 218 to pass through one or more of the brackets 326, as described in greater detail below. The rounded shape of the lug 218 can help guide the zipper tape 202 through the length of the track 300 by reducing the engagement of the lug 218 with the flange 332. In some examples, the lug 218 can have various different profiles, such as a profile that matches the profile of the track 300. In some examples, the width dimension of the neck 222 can be greater than the gap 330, and / or the width dimension XI of the lug 218 can be greater than the channel 328, and the zipper tape 202 can be compressed to fit accordingly in the gap 330 or channel 328. By compressing the zipper tape 202, a friction fit can limit or reduce the motion or undesired movement of the zipper tape 202 relative to the housing or track 300.

[0122] The optional rib 220 can limit the motion of the zipper tape 202 relative to the track 300. For example, the rib 220 can prevent or limit the zipper tape 202 from moving orthogonally further through the gap 330 in a direction toward the inner surfaces 310, 316 of the first and second flanges 306, 308. Thus, the rib 220 can reduce the motion or undesired movement of the zipper tape 202 (e.g., in the orthogonal direction of extension of the track 300) relative to the track 300. The width dimension X3 of the rib 220 can be greater than the gap 330 and in contact or engagement with the outer surfaces 312, 318 of the first and / or second flanges 306, 308.

[0123] Accordingly, the zipper tape 202 can be retained by the track 300 with the ribs 220 on the outer sides 312, 318 of the first and second flanges 306, 308, the lugs 218 received in the channels 328, and the necks 222 positioned in the gaps 330. While Figure 5A And 5B The ribs 220 and lugs 218 are shown extending from both sides of the zipper tape 202, in other examples, the lugs 218 and / or ribs 220 can alternatively extend only in the interior or exterior direction. Each of the lugs 218 and ribs 220 can also extend in opposite directions relative to one another.

[0124] Referring to Figure 2 And 5A -5B, the closure assembly 200 can be engaged with the track 300 at the entry region 194. With the retention features 216 engaged with the track 300, the closure assembly 200 can be moved along the track 300 on each of the luggage shells 118 and guided around the perimeters 134 of the shells 118, 120. The closure assembly 200 can be flexible enough to allow it to bend as it slides along the track 300, for example when it passes around a corner. In some examples, the two shells 118, 120 can be aligned such that the closure assembly 200 can engage at least a portion of the tracks 300 of both shells 118, 120 during installation. Alternatively, in the case where the luggage shells 118, 120 are not in a closed configuration and are separately accessible, each zipper tape 202 can be installed on the respective track 300 of each respective shell 118, 120 individually. The shells 118, 120 can then be configured such that their respective perimeter edges 132 are adjacent to one another, and the zipper tapes 202 can then be engaged with one another to form the closure assembly 200.

[0125] The closure assembly 200 can also be sufficiently rigid to overcome friction during insertion. In the example described, the extrusion 208 of each zipper tape 202 can exhibit a suitable combination of flexibility and rigidity to aid passage along the track 300 as it slides into place. For example, the extrusion 208 can be made of a material such as an elastomer. In some examples, the extrusion 208 can be a thermoplastic elastomer. The Shore hardness value of the extrusion 208 can be between A60 and A90. In some examples, the extrusion can define openings or features to aid bending or elastic deformation as the zipper tape extends around the corner regions of the housing. The closure assembly 200 can extend along all or part of the length of the track 300 on each housing 118, 120. The track 300 on each housing 118, 120 can extend along all or part of the perimeter 134 of each luggage housing 118, 120 (e.g., continuously or discontinuously). In one example, the track 300 may extend from one end of the hinge structure 170 along the periphery 134 of each housing 118, 120 to the other end of the hinge structure 170.

[0126] When the zipper tape 202 is placed in the track 300 of each housing, the zipper teeth 210 of each zipper tape 202 can engage with each other to come together and form a closing assembly 200. The closing assembly 200 can hold the first housing 118 and the second housing 120 in a closed configuration.

[0127] like Figure 5B As shown, in some examples, a secondary closure assembly 260 may be included. In one example, the secondary closure assembly 260 may be a lining zipper assembly for attaching a lining or additional feature along the interior 136 of the housing 118. The secondary closure assembly 260 may include a secondary zipper strip 264 that selectively engages with the lining zipper strip 266. The secondary zipper strip 264 may engage with the lining zipper strip along a secondary inter-engaging feature 262. The secondary zipper strip 264 may be coupled to the zipper strip 204 of the zipper tape 202. For example, the secondary zipper strip 264 may be sewn to the zipper strip 204 (e.g., at the seam connection 212). The secondary zipper strip 264 may be positioned inside the zipper strip 204. In some examples, the secondary zipper strip 264 may be attached or engaged with an extruder 208.

[0128] Figure 6An example of a closure assembly 200 including an expansion assembly 270 is shown. The expansion assembly 270 can include a middle zipper strip 272 coupled to the zipper strip 204 by interengaging features 206. The middle zipper strip 272 can be coupled to an end zipper strip 278 by selectively actuating an expansion mechanism 276. An expansion portion 274 can extend from the middle zipper strip 272 to the end zipper strip 278. When the expansion mechanism 276 is actuated, the expansion portion 274 can allow the width or distance between the middle strip 272 and the end strip 278 to increase. When the expansion mechanism 270 is in an open configuration, the expansion portion 274 can prevent access to the interior storage volume 130. Thus, the expansion assembly 270 can allow a user to increase the width dimension between the retention features 216 of the closure assembly 200. By increasing the width dimension, the interior storage volume 130 of the luggage 100 accessible by actuation of the pull tab 224 can be increased.

[0129] With respect to Figure 7 Another example of a luggage 1000 is shown. The luggage 1000 can include the same or similar features as described above with respect to the luggage 100. The luggage 1000 can include two or more shells, such as a first or top shell 1118 and a second or bottom shell 1120. The top shell 1118 and the bottom shell 1120 can be selectively coupled along a connection line 1122 by a closure assembly 1200. It should be understood that the shells 1118, 1120 can include similar or identical features as the shells 118 and 120 described elsewhere herein. The shells 1118, 1120 can be coupled along the sides by one or more discrete hinges 800. The hinges 800 can be placed along the exterior surface or sides 1138 of the luggage 1000. The luggage 1000 can include a retractable trolley handle 1126.

[0130] The hinge 800 can include a body 801 defining a first end 802, a second end 804, and a connecting or middle portion 806 extending between the first end 802 and the second end 802. Each of the first side 802 and the second side 804 can be rectangular in shape. The middle portion 806 can extend between or be attached to the first side 802 and the second side 804. The middle portion 806 can be a flexible and / or durable material.

[0131] The main body 801 may be attached to housings 1118, 1120 to define hinge 800. For example, the main body 801 may be attached at a first end 823 and / or a second end 825 of housings 1118, 1120. A first side 802 may be attached to the top housing 1118. A second side 804 may similarly be attached to the bottom or second housing 120. The intermediate portion 806 may be flexed or bent to allow housings 118, 120 to move relative to each other from an open configuration to a closed configuration, and in the opposite direction.

[0132] Figure 8A An example housing 1120 is shown, including a joining structure 1400, which includes an integrally formed track 1300, and a zipper strap 1202 of a closing assembly 1200 is partially inserted along the track 1300. Figure 8B An enlarged view of track 1300 is shown, including... Figures 9A-9E A view of an example housing 1120 and a track 1300 is shown. In the various figures, the track 1300 is shown receiving and securing the zipper tape 1202.

[0133] like Figure 8A , Figure 8B , Figure 9A and Figure 9E As shown, track 1300 can be positioned on or near the periphery or edge 1132 of housing 1120. In one example, track 1300 can be positioned on the interior 1136 of housing 1120. Track 1300 may include a first portion or flange 1306 extending from housing 1120. Track 1300 may include a second flange or portion 1308 extending from housing. The first flange 1306 or the second flange 1308 may be coupled to housing 1120 (e.g., extending indirectly from housing 1120) or extend directly from housing 1120. Track 1300 or the first flange 1306 or the second flange 1308 may be continuous or discontinuous. For example, two or more first flanges 1306 or second flanges 1308 may be positioned at discrete locations along track 1300. The first flanges 1306 and second flanges 1308 may be positioned adjacent to each other, for example, in pairs. In some examples, the first flange 1306 and the second flange 1038 may be offset or staggered along the track 1300. In discontinuous examples, the first flange 1306 or the second flange 1308 may have different lengths or other dimensions. For example, one first flange 1306 may extend a larger portion of the track 1300 than the second first flange 1306.

[0134] The first flange 1306 and the second flange 1308 can be spaced apart to define a gap 1330 to receive the zipper tape 1202. The gap 1330 can be defined along a length of a portion of the track 1300 that defines the channel 1328.

[0135] The track 1300 can include a support member 1326. The support member 1326 can extend between the housing 1120 and the second portion 1308. In some examples, the support member 1326 can attach the second flange 1308 to the housing 1120. The support member 1326 can define a bottom or depth of the gap 1330. In one example, the support member 1326 and the first flange 1306 and the second flange 1308 define the channel 1328. A portion of the support member 1326 can define a guide flange 1327. For example, a top of the support member 1326 can include or define a support or guide flange 1327. The guide flange 1327 can have a width that is greater than the support member 1326. For example, the guide flange 1327 can extend relative to the support member 1326 along a direction of the channel 1328 or the track 1300. The support flange 1327 can help guide the zipper tape 1202 along the track 1300.

[0136] The track 1300 can include an optional guide feature or inner rim 1322 that extends from the second flange 1308. The optional inner rim 1322 can help guide the zipper tape 1202 through the track 1300 or protect the zipper tape 1202 from items stored in the luggage 1000. The track 1300 can include optional support fins or flanges 1332 that extend from the housing 1120 and are attached or joined with the support member 1326. The support fins 1332 can extend between the support member 1326. The support fins 1332 can be continuous or discontinuous.

[0137] The track 1300 can define an access region 1194 to allow the zipper tape 1202 to be inserted into the gap 1330. The access region 1194 can be an opening in the track at or near the gap 1330. In one example, the access region 1194 is an example of a discontinuous track 1300 and can include an opening in the track formed by end portions of the track 1300 spaced apart by a break (e.g., 4-6 cm). For example, the access region 1194 can be defined between a first end 1350 of the track 1300 and a second end 1352 of the track 1300 spaced apart along the rim 1132. In one example, the access region 1194 is positioned on the interior 1136 of the housing 1120. In some examples, as described in greater detail below, the hinge 800 can be attached or connected to the housing 1120 at the access region 1194. The housing 1120 can define an access hole 1196 at the access region 1194 between the interior 1136 and the exterior 1138 of the housing.

[0138] As previously described, the closure assembly 1200 and the zipper tape 1202 can include the same or similar features and functionality as the closure assembly 200 and the zipper tape 202, respectively. For example, the zipper tape 1202 can include a zipper string 1204 and an extrusion 1208. The zipper string 1204 can define or include interengaging features 1206, such as zipper teeth or zipper coils, along an edge. The extrusion 1208 can include a retention feature 1216 to selectively engage the track 1300. The retention feature 1216 can be spaced apart from the interengaging features 1206. The retention feature 1216 can include a lug or flange 1218 or otherwise enlarged portion. The retention feature 1216 can include a neck 1222 spaced apart from the lug 1218. The retention feature 1216 can include one or more ribs 1220 adjacent to the neck 1222, opposite and spaced apart from the lug 1218.

[0139] The zipper tape 1202 can include a first end 1270. The zipper tape 1202 can include a second end 1272 opposite the first end 1270. The zipper tape 1202 can define a hole 1275 at the first end 1270 or the second end 1272. The hole 1275 can be defined by the zipper string 1204, the extrusion 1208, or both.

[0140] As Figure 8A and 9BAs shown, the zipper tape 1202 can be inserted into the track 1300 at the entry area 1194. For example, the second end 1272 of the tape 1202 can be inserted into the first end 1350 of the track 1300. A retaining feature 1216 can engage the track 1300. For example, a neck 1222 can be inserted between the first flange 1306 and the second flange 1308, for example, in the gap 1330. A lug 1218 can be positioned in the channel 1328. The zipper tape 1202 can be moved in the insertion direction 1340 until it is fully inserted. For example, when fully inserted, the first end 1270 of the zipper tape 1202 can be positioned at or near the first end 1250 of the track 1300. In some examples, the track 1300 can be continuous or discontinuous. The zipper tape 1202 can be continuous or discontinuous. After insertion, the zipper tape 1202 can extend into or align with the entry area 1294. For example, the zipper hole 1275 can be aligned with the entry hole 1196.

[0141] To secure the zipper tape 1202 to or within the track 1300, the hinge 800 may include features for connection to the housing 1120 and the zipper tape 1202. The hinge 800 may include an attachment feature or anchor 810. For example, the anchor 810 may be an elongated feature extending from the hinge 800. The anchor 810 may extend from either or both of the first side 802 or the second side 804. In one example, the attachment feature 810 may include a shaft 813 having an enlarged end 816. The anchor 810 may be inserted through an access hole 1196 to engage the hinge 800 to the housing 1120. The anchor 810 may be inserted through a zipper hole 1275 to secure the zipper tape 1202 to the track 1300 or the housing 1120. For example, the shaft 813 may be positioned within holes 1196 and 1275, and the enlarged end 816 may extend through holes 1196 and 1275. The hinge 800 can be attached to any one or both of the housings 1180 and 1200 before or after the closing assembly 1200 is installed in the track 1300.

[0142] like Figure 9D As shown, in some examples, fastener 900 can also secure hinge 800 or zipper tape 1202 to housing 1120. Fastener 900 can be coupled to an anchor or attachment feature 810 of hinge 800. Fastener 900 may include a hole 902 to receive the anchor 810 of hinge 800. Fastener 900 may extend between the ends of anchor 810 or zipper tape 1202. Fastener 900 can be attached to housings 118, 120 by additional fasteners, adhesives, or additional features.

[0143] refer to Figure 10In some examples, the shell 1120 can define an anchor or attachment feature 1810. For example, the anchor 1810 can extend from the shell 1120. In one example, the anchor 1810 extends from the inner surface 1136 of the shell 1120. The anchor 1810 can include an enlarged end or portion 1819. The anchor 1810 can extend through the zipper tape hole 1275. The enlarged end 1819 can be on the inside of the zipper tape 1202 to secure the zipper tape 1202 in the track 1300.

[0144] Figure 11 An example of the track 1300 near the corner region 1160 of the shell 1120 is shown. In some examples, at or near the corner region 1160, features of the track 1300 can be arranged to improve the guidance of the zipper tape 1202 through the passage 1328. For example, the zipper tape 1202 can be received by the track 1300 in the passage 1328 with the second end 1272 facing the insertion direction 1340.

[0145] With continued reference to Figure 11 , the first flange 1306 or the second flange 1308 can be continuous. In some examples, the first flange 1036 or the second flange 1308 can be discontinuous, meaning that the flange 1306 or 1308 can be or include multiple spaced apart features or features that extend different distances from the shell 1120. In one example, the first flange 1306 and the second flange 1308 can be offset or staggered. Also as Figure 8B shown, the first flange 1306 can include a first leading edge 1366 on the approach side relative to the insertion direction 1340. Also as Figure 8B shown, the second flange 1308 can include a second leading edge 1368 on the approach side. Either or both of the leading edges 1366, 1368 can be curved or angled. The support member 1326 can be angled at the corner region 1160. In one example, the first flange 1306 and the second flange 1308 are discontinuous or segmented to allow the zipper tape 1202 to bend without binding or increasing resistance through the corner region 1160. The leading edges 1366, 1388 can help guide the zipper tape 1202 through or back to the passage 1328 during insertion. For example, as Figure 11 shown, the curvature or angle of the leading edges 1366, 1368 can guide or direct the free end 1272 of the zipper tape 1202 toward the gap 1330 or through the passage 1328.
