Description

Technical Field

[0001] The present invention generally relates to luggage having a closure assembly, and more particularly to mounting and attaching the closure assembly to the luggage. Background Art

[0002] Existing luggage typically includes a zipper or other closure assembly to selectively connect two housings of the luggage. To attach the closure assembly to the housing, it is generally necessary for a technician to correctly align the closure assembly and the housing and manually attach the closure assembly to the housing, such as by stitching. Thus, attaching the closure assembly to the luggage is often a time - and cost - intensive aspect of manufacturing the luggage.

[0003] Accordingly, there is a need for a more cost - effective solution for attaching a closure assembly to luggage. Summary of the Invention

[0004] In one example of the present disclosure, a luggage is disclosed. The luggage includes at least one housing defining an edge, a zipper tape, and a joining structure selectively coupling the zipper tape and the housing. The joining structure includes 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, and wherein one of the housing or the zipper tape includes the integrally formed track and the other of the housing or the zipper tape includes the retaining feature.

[0005] In some examples of the luggage, the selective coupling of the track and the retaining feature helps to align the closure assembly and the housing during the assembly process.

[0006] In some examples of the luggage, the closure assembly is selectively removable from the housing.

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

[0008] In some examples of the luggage, a portion of the housing is received inside the zipper tape.

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

[0010] In some examples of the luggage, the housing is injection molded.

[0011] In some examples of the luggage, the housing is injection molded and the track is integrally molded to the housing.

[0012] In some examples of the luggage, a portion of the zipper tape is received inside the housing.

[0013] In some examples of the luggage, the retaining feature is slidably received by the track.

[0014] In some examples of the luggage, the track includes a first flange extending from the housing and a second flange extending from the housing and spaced from the first flange to form the gap.

[0015] In some examples of the luggage, the first flange is continuous or discontinuous.

[0016] Discontinuous can mean that the first flange includes separately defined and spaced-apart portions, or that the first flange extends from the housing at different distances.

[0017] In some examples of the luggage, the second flange is continuous or discontinuous.

[0018] Discontinuous can mean that the second flange includes separately defined and spaced-apart portions, or that the second flange extends from the housing at different distances.

[0019] In some examples of the luggage, the first flange and the second flange are discontinuous and a plurality of the first flanges and the second flanges define a leading edge to guide the zipper tape along the track.

[0020] In some examples of the luggage, the leading edge guides the inserted retaining feature into the gap. Thus, the curved edge can help couple the track and the retaining feature.

[0021] In some examples of the luggage, the first flange and the second flange are located around a corner region. Additionally or independently, the first flange and the second flange are offset from each other.

[0022] In some examples of the luggage, the retaining feature includes a lug along a portion of the edge of the zipper tape, a neck adjacent to the lug, the width dimension of the lug being greater than the width of the gap, and the gap receiving the neck, wherein the lug engages the inner surface of the first flange or the second flange to hold the zipper tape in the track.

[0023] In some examples of the luggage, the lug having a width dimension greater than the gap prevents the lug from being removed in a direction transverse to the track.

[0024] In some examples of the luggage, the lugs extend along opposite sides of the zip strip.

[0025] In some examples of the luggage, the lugs extend outwardly from opposite sides of the zip strip to form a T-shape, and the lugs extend along at least a portion of the length of the zip strip.

[0026] In some examples of the luggage, the lugs are continuous or discontinuous.

[0027] Discontinuous can mean that the lugs include separately defined and spaced-apart portions, or that the lugs extend along the edge with different thicknesses.

[0028] In some examples of the luggage, the retaining feature includes a rib that extends along a portion of the length of the zip strip and is spaced from the lug by the neck, the neck being positioned between the rib and the lug, and the width dimension of the rib being greater than the width dimension of the gap, and the gap receiving the neck, wherein the rib is on the outer side of the track.

[0029] In some examples of the luggage, the rib having a width dimension greater than the gap positions the lug at the required depth in the track.

[0030] In some examples of the luggage, the rib forms a "T" shape. Additionally, the rib extends outwardly from the inner-facing side or the outer-facing side of the zip strip. Additionally or alternatively, the rib extends outwardly from the zip strip.

[0031] In some examples of the luggage, the rib is symmetric, or in other examples, the rib is asymmetric.

[0032] In some examples of the luggage, the rib is continuous or discontinuous.

[0033] Discontinuous can mean that the rib includes separately defined and spaced-apart portions, or that the rib extends along the edge with different thicknesses.

[0034] In some examples of the luggage, the track includes at least one support member extending between the housing and the second flange.

[0035] In some examples of the trunk, the second flange is supported by at least one support member that extends from the housing and defines a cutout to receive the lug of the zipper tape.

[0036] In some examples of the trunk, the at least one support member extends in a direction orthogonal to the housing.

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

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

[0039] In some examples of the trunk, a guiding flange (1327) is formed on a part of the at least one support member that defines the cutout.

[0040] In some examples of the trunk, the housing includes a supporting flange that extends from the housing and is spaced apart from the track, and the at least one support member extends between the flange and the supporting flange.

[0041] In some examples of the trunk, the supporting flange defines a connection between the housing and the second flange.

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

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

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

[0045] In some examples of the trunk, the cutouts in each of the plurality of support members are at least partially aligned to form a channel to receive the retaining feature.

[0046] In some examples of the trunk, the track includes a plurality of support members, the plurality of support members includes the at least one support member, the plurality of support members includes a plurality of cutouts, the plurality of cutouts includes the cutout, and the plurality of cutouts in each of the plurality of support members are at least partially aligned to form a channel to receive the retaining 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.

[0050] In some examples of the luggage, the hinge is attached to the first and second shells at discrete locations.

[0051] In some examples of the luggage, the hinge includes at least two discrete hinges, at least one of the hinges being attached to the first and second shells and to respective ends of the zipper tape.

[0052] In some examples, an anchor couples at least one of the respective ends of the zipper tape to the at least one shell. In one example, the at least one shell defines the anchor.

[0053] In some examples of the luggage, the hinge includes an outwardly extending elongate feature defining an anchor, and the end of the zipper tape is coupled to the anchor to secure the zipper tape in position relative to the shell. In some examples, the anchor is received in a hole defined by at least one of the respective ends of the zipper tape to couple to the at least one shell.

[0054] In some examples of the luggage, the at least one hinge includes a body having a flexible middle portion, the flexible middle portion being attached at one end to the first shell and at the other end to the second shell to permit pivotal movement between the first and second shells.

[0094] This application may disclose a luggage case having a track to engage a closure assembly. The luggage case may include a body having two or more housings attached by hinges. Each housing may define a track extending along at least a portion of the perimeter of each housing. The closure assembly may be attached to the perimeter of each housing and allow selective access to the interior volume of the luggage case. The closure assembly may be removably attached to the track on each housing. The closure assembly may include two zip tapes, each zip tape including zip teeth on a first edge and a retaining feature on a second edge. The zip teeth on each zip tape may engage to link the zip tapes together to form the closure assembly. The retaining feature of each zip tape may be attached to or removed from a corresponding track on each housing. Thus, the closure assembly can be simply mounted on or removed from each housing. In some examples, the housing may include a retaining feature and each zip tape may include a track. Additionally, the closure assembly can be removed from the housing and replaced when damaged, rather than replacing the entire luggage case. Each housing, or two or more housings together, may define an entry area or an entry opening for attaching or removing the closure assembly, or one or two zip tapes, to or from the track. For example, the entry area may be located near the end of the track.

[0095] In some examples, the housings can be joined together by hinge portions. For example, the hinge portions can include a plurality of integrally molded bosses formed along a portion of the perimeter of the housings. The bosses of each luggage housing can be joined together to receive a hinge pin to form a hinge structure and pivotally connect the housings together. In another example, the hinge portions can be discrete features coupled to or positioned along a portion of the perimeter of the housings. The discretely positioned hinge portions can assist in securing a zipper tape to the housings or tracks. In one example, the mating bosses can be referred to herein and include staggered or interlaced bosses.

[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 piece of luggage, a bag, a trolley, etc. In one example, the luggage 100 can be an upright hard-sided luggage, such as a spinner luggage. In other examples, the piece of luggage 100 can be many types of luggage, including a soft-sided spinner luggage with a molded frame or inner shell, a hybrid spinner luggage, a container, etc. The luggage 100 can have a body 102 having a plurality of panels that define an internal storage volume for carrying a user's items.

[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 panel 108 and right panel 110. Each panel can have an outer surface 138 and an inner surface 136 that together define an internal storage volume 130. The luggage 100 can move between a closed configuration and an open configuration to provide access to the internal storage volume 130, in the closed configuration, the edges or perimeters 134 of two or more housings 118, 120 of the body 102 are positioned adjacent to each other. 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 two or more housings 118, 120. The two or more housings 118, 120 can include a first housing 118 and a second housing 120, the first housing 118 can be referred to as a top housing or lid, and the second housing can be referred to as a bottom housing or base housing. Reference can be made to either the first housing 118 or the second housing 120, but it should be understood that either housing can include the same or similar feature structures.

[0098] The housings 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 housings 118, 120. In some examples, the hinge 170 can be formed separately and attached to the housings 118, 120 or integrally formed with the housings 118, 120. Each housing 118, 120 can be made entirely or partially of an injection-molded polymer. Each housing 118, 120 can be formed as a single unit having at least some of the features of the housings 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 in part by an injection molding process. The soft-sided luggage 100 can be made by injection molding all or part of the peripheral portions of each housing 118, 120 and attaching the soft-sided outer portions and the required frame members thereto. Exterior or additional features can be attached to the molded portions of the luggage 100.

[0099] In some examples, the luggage item 100 can include one or more carrying handles 128 and / or a retractable towing handle 126 that can extend from a recess or depression in the rear panel 106 of the luggage item 100. The retractable towing handle 126 can extend out of and retract into the recess and can allow a user to pull or tow the luggage item 100. The luggage item 100 can include one or more foot elements 148, such as wheels, casters, spinner assemblies, posts, etc., to support or enable the luggage item 100 to move on a support surface (e.g., a floor, street, sidewalk, or ground).

[0100] The luggage 100 can include a hinge 170 positioned along the panels 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 housing 118, 120. In one example, the bosses 172 are integrally molded with the housings 118, 120. When the housings 118, 120 are positioned together, the bosses 172 of each housing 118, 20 interleave. Each boss 172 includes a hole 174 formed therethrough, and when interleaved, the holes 174 are aligned. The bosses 172 on one housing 118, 120 can be pivotally coupled to the bosses 172 on the other housing 118, 120 by a rod or pin to form a hinge pin, and the rod or pin is positioned through the bosses 172 by being received in the aligned holes 174. 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 is removable and can be replaced when damaged or pivotally attach different housings 118, 120 together.

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

[0102] In some examples, during installation, the two housings 118, 120 may be aligned, and the closure assembly 180 may engage the tracks 190 of the two housings 118, 120. In other examples, the zipper assembly 180 may include a first zipper tape 182A and a second zipper tape 182B. The zipper tapes 182A, 182B may define retention features. The retention feature of the first zipper tape 182A of the closure assembly 180 may separately engage the first track 190A of the first housing 118, and the second zipper tape 182B in the closure assembly 180 may engage the second track 190B of the second housing 120. After installation, the first zipper tape 182A may then selectively engage the second zipper tape 182B to form the closure assembly 180. Although a description is given of defining the track 190 by the housing 188, in some examples, the closure assembly 180 may define the track 190. Similarly, the retention features may be defined by the housings 118, 120. Thus, in some examples, the housings 118, 120 may define retention features, and the zipper assembly 180 may define one or more tracks 190, and the track 190 of the closure assembly 180 may receive the retention features of the housing 118 or 120.

[0103] The closing assembly 180 can be received onto the track 190 at a defined location of the track 190 (e.g., at the entry region 194 of the track 190). In one example, the entry region 194 can be an opening formed in the housing 118 that permits entry onto 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 the ends of the track 300 or the housings 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 start or end of the track 190. The entry region 194 can be defined by the housing 118 or the housings 118, 120. The entry region 194 can be an opening defined between two spaced - apart portions on an outer side of the track 190 or an exterior 138 of the housings 118, 120. For example, the entry region 194 permits entry onto the track 190 from the exterior 138 of the housing 118, where the track 190 is formed on the housing 118. In some examples, the entry region 194 can be positioned at an 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 permit entry onto the track 190. For example, the entry region 194 can be defined between two ends of the track 190 spaced apart along the interior 136 of the housing 118. The closing assembly 180 can be flexible to follow the path of the track 190 around at least a portion of the perimeter 134 of the trunk housing 118 or the housings 118, 120 when attached to the track 190.

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

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

[0106] In Figures 3A to 3BTherein, an exemplary closure assembly 300 is shown. The closure assembly 300 may also be referred to as a slide-in closure assembly 300. The closure assembly 330 may include two zipper tapes 202A, 202B that are selectively engageable along a connection line 122. Each zipper tape 202 may include mating features 206 (such as zipper teeth or zipper coils) and one or more retention features 216. The mating features 206 may connect the zipper tapes 202A and 202B. The mating features 206 may extend along at least a portion of the length of the inner edge 232 of the zipper tape 202. The retention features 216 may engage the track 300 or prevent the zipper tape 202 from being removed from the track 300. The retention features 216 may extend along at least a portion of the length of the outer edge 230 of the zipper tape 202. The retention features 216 may be continuous. For example, the retention features 216 may extend along a portion of the length of the outer edge 230. In other examples, the retention features 216 may be segmented or discontinuous. For example, the retention features 216 may include separate portions spaced apart along the outer edge 230, or may extend different widths from the outer edge 230. The retention features 216 may be defined as or include lugs 218. Optional retention features 216 may include ribs 220 that extend along at least a portion of the length of the zipper tape 202 and are spaced apart from the lugs 218 toward the inner edge 232. The optional ribs 220 may be continuous or discontinuous. A neck 222 may be defined by the zipper tape 202 adjacent to the lugs 218. When the optional ribs 220 are present, the neck 222 may 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, and the zipper tape 202 moves in a direction parallel to the track 300, where the neck 222 passes through 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 X1. In one example, the width dimension can be between 10 millimeters and 15 millimeters. The width dimension X1 of the lug 218 can be greater than the gap 330, inhibiting or preventing the zipper tape 202 from moving out of the track 300. For example, the width dimension X1 prevents the zipper tape 202 from being removed through the gap 330 in the direction 340 towards the mating feature 206. This lug structure 218 also allows the zipper tape 202 to move along the track 300 in the direction of the gap 330 (e.g., by sliding). Optional ribs 220 can be positioned on the zipper tape 202 at the ends of the neck 222 opposite the lug 218. The ribs 220 (if present) inhibit or prevent the zipper tape 202 from moving out of the track 300 (e.g., from the gap 330) in a direction away from the mating feature 206. This rib structure 220 also allows the zipper tape 202 to move along the track 300 in the 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 ribs 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 elongate pull chain 204 positioned on or attached to the inner edge 240 of the extrudate 208 along the outer edge 234. The extrudate 208 can be or define the retention feature 216. In one example, the pull chain 204 can be formed of a braided material. In one example, the extrudate 208 can be made of a plastic material and, in one example, formed by an extrusion process. As Figure 3A and Figure 3B shown, the pull chain 204 can be connected or attached to the extrudate 208 by stitching 212. In some examples, the pull chain 204 can be connected or attached to the extrudate 208 during extrusion or molding of the extrudate (e.g., overmolding). In some examples, the pull chain 204 can be attached to the extrudate 208 by an adhesive or fastener. In this example, the mating feature 206 can be positioned along the inner edge 232 of the pull chain 204.

[0109] The lug 218 can extend along the outer edge 230 of the extruded member 208. As described above, the optional rib 220 can extend along the extruded member 208 spaced apart from the lug 218. The neck 222 can be defined by the extruded member 208 adjacent to or spaced apart from the lug 218. In the presence of the rib 220, the neck 222 can be defined by the extruded member 208 between the lug 218 and the rib 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 lug 218 can extend away from one or both sides of the extruded member 208. In the presence, the rib 220 can extend away from one or both sides of the extruded member 208. In another example, the zipper tape 202 can be made entirely of the zipper chain 204, where the mating features 206 and the retaining features 216 (e.g., the lug 218, the neck 222, the optional rib 220) are attached to the zipper chain 204 and positioned as in the above example. In another example, the zipper tape 202 can be made entirely of the extruded member 208, where the mating features 206 and the retaining features 216 (e.g., the lug 218, the neck 222, the optional rib 220) are attached to the extruded member 208 and positioned as in the above example.

[0110] The mating features 206 (e.g., the zipper teeth 210) can be selectively joined 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 and an inner side 252, the outer side 250 being configured to be visible from the outside of the luggage 100, and the inner side 252 being 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 mounted on the track 300 on the respective housings 118, 120 to define the respective engagement structures 400. In another example, each zipper tape 202 can be individually removed from the respective housings 118, 120. In another example, a replacement zipper tape 202 can be individually mounted on the track 300 on the respective housings 118, 120 to replace the zipper tape 202 removed from the respective housings 118, 120. This can allow the user to replace only a part of the closure assembly 200, or combine different zipper tapes 202 with desired features, or achieve a desired aesthetics (e.g., color or texture). The closure assembly 200 can also be flexible to assist in removing or installing the closure assembly 200 into the track 300.

[0112] Continuing to refer Figure 3A and 3B, the lug 218 can have a width dimension X1 greater than the width of the peripheral portion of the zipper tape 202. In one example, the width dimension X1 is about 10 to 15 millimeters. The width dimension X1 can be greater than the 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-shaped configuration. The lug 218 can extend toward either or both of the inner side 252 and the outer side 250. Each pointing side of the lug 218 can be referred to as a first and second lug, collectively as lugs, or together as a single lug. The lug 218 can have an outer surface defining a rounded outer profile. The lug 218 can have an inner surface which, in one example, can extend at a right angle to the zipper tape 202. In other examples, the lug can define various geometries or shapes (e.g., rectangular, triangular, etc.). The rib 220 can have a width dimension X3 greater than the width of the peripheral 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] Reference Figure 2 Go to Figure 4A And 4B , shows that the track 300 can be formed on the perimeter 134 of the luggage housing 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 housing 118 and be positioned on the inner 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-apart portions, or the track 300 can have different heights or thicknesses along portions of the housing 118. The track 300 can be spaced from 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 housing 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 for the luggage housing 118 (e.g., along the perimeter 134). In some examples, the track 300 can be formed separately or attached to the housing 118. For example, the track 300 can be a separate component or part attached to or mounted on the frame of the housing 118. For example, the track 300 can be attached to the housing 118 by fasteners (such as rivets or screws, etc.). The track 300 can be made of a molded material (such as a polymer or plastic) or metal (such as aluminum). In some examples, the track 300 can be attached to the housing 118 through corresponding attachment features (such as holes defined in the track 300 or the housing 118) to receive the posts or snap features of the other. In some examples, the track 300 can be attached to the housing 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 housing 118. In one example, the first flange 306 can extend away from the housing 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 housing 118. For example, the second flange 308 can be coupled to the housing 118 (e.g., extending indirectly from the housing 118) or directly extend from the housing 118. The second flange 308 can be continuous or discontinuous. The second flange 308 can also include an inner edge 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 edge 322 can help align the zipper tape 202 in the track 300. The inner edge 322 can also protect the zipper tape 202 from the contents in the internal volume of the luggage 100.

[0118] The second portion 308 can be connected to the housing 118 by one or more support members 326 extending from the inner surface 136 of the housing 118. The support members 326 can extend from the housing 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 a gap 330. The support members 326 can be walls or fins extending from the housing 118. The support members 326 can be orthogonally or perpendicularly oriented with respect 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 inner surface 310 of the first flange 306 and / or the inner surface 136 of the housing 118 and can provide some structural support to the first flange 306 if 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 notch 328 oriented with respect to the track 300. For example, each support member 326 can define a notch 328 adjacent and surrounding the gap 330, the notch 328 sized to permit a lug 218 of the zipper tape 202 to extend through the gap 330, the lug 218 being on the inner surface 310, 316 of at least one of the first flange 306 and the second flange 308, as Figure 5A shown. The shape of the notch 328 can match the shape of a portion of the zipper tape 202. In some examples, the track 300 includes a plurality of support members 326 having a plurality of notches 328 defining a channel 328. The notches 328 can be at least partially aligned along a portion of the track 300 to define the channel 328. In other examples, the support member 326 can be a relatively wide continuous feature and extend along at least a portion of the track 300. The notch 328 can be formed in the wider or continuous bracket 326 to define a channel 328 to receive one or more lugs 218. Alternatively, the channel 328 can be shaped to have a major dimension that can be greater than the width dimension X1 of the zipper tape 202.

[0120] Optional support flanges 332 can extend from the inner surface 136 of the housing 118. The support flanges 332 can engage a portion of one or more brackets 326 to provide a support structure. For example, one or more support members 326 can extend between the housing 118 and the support flanges 332. In some examples, the support members 326 can extend between the support flanges 332 and the second flange 308. The support flanges 332 can extend along at least a portion of the inner surface 136 of the housing 118 and along at least a portion of the track 300. The support flanges 332 can also serve as a point of engagement for a lining or other feature of the luggage 100 to be attached to the housing 118.

[0121] Figure 5A shows an example of a joining structure 400 including a closure assembly 200, the closure assembly 200 being held along opposite edges by tracks 300 formed on each of the housings 118, 120, as Figure 5B shown. Figure 5B is Figure 5A an enlarged view of the joining structure 400 of, and shows a single zip tape 202 positioned within the track 300. When positioned within the track 300, the neck 222 may extend through the gap 330, and the lug 218 is positioned on and / or against the inner surfaces 310, 316 of the first flange 306 and the second flange 308. The neck 222 may be configured to engage or mate with the gap 330 defined between the end faces 314, 320 of the first flange 306 and the second flange 308. The lug 218 may be received within a channel 328 formed by the bracket 326. Since the size of the lug 218 is greater than the size of the gap 330, the zip tape 202 may be retained within the track 300, and thus the zip tape 202 may not be pulled out in a direction transverse to the direction in which the gap 330 extends, as Figure 5A and 5B shown by the arrow 340 in. The width dimension X1 of the lug 218 may be less than the width dimension of the channel 328 to allow the lug 218 to pass through one or more brackets 326, as described in more detail below. The rounded shape of the lug 218 may help guide the zip 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 may 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 may be greater than the gap 330, and / or the width dimension X1 of the lug 218 may be greater than the channel 328, and the zip tape 202 may be compressed to fit within the gap 330 or the channel 328 accordingly. By compressing the zip tape 202, a friction fit may limit or reduce the movement or undesired movement of the zip tape 202 relative to the housing or the track 300.

[0122] Optional ribs 220 may limit the movement of the zip tape 202 relative to the track 300. For example, the ribs 220 may prevent or limit the zip tape 202 from moving orthogonally further through the gap 330 in a direction towards the inner surfaces 310, 316 of the first flange 306 and the second flange 308. Thus, the ribs 220 may reduce the movement or undesired movement of the zip tape 202 (e.g., in an orthogonal direction to the extension of the track 300) relative to the track 300. The width dimension X3 of the ribs 220 may be greater than the gap 330 and contact or engage the outer surfaces 312, 318 of the first flange 306 and / or the second flange 308.

[0123] Accordingly, the zipper tape 202 can be held by the track 300, where the ribs 220 are on the outer sides 312, 318 of the first flange 306 and the second flange 308, the lugs 218 are received in the channels 328, and the necks 222 are positioned in the gaps 330. Although Figure 5A and 5B the ribs 220 and the lugs 218 extending from both sides of the zipper tape 202 are shown, in other examples, the lugs 218 and / or the ribs 220 can alternatively extend only in the inner or outer direction. Each of the lugs 218 and the ribs 220 can also extend in opposite directions relative to each other.

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

[0125] The closing assembly 200 can also be rigid enough to overcome the friction during the insertion process. In the example, the extrusions 208 of each zip strip 202 can exhibit an appropriate combination of flexibility and stiffness to assist in passing 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 an opening or feature to assist in bending or elastic deformation as the zip strip extends around the corner regions of the housing. The closing assembly 200 can extend along all or a portion 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 a portion of the perimeter 134 of each luggage housing 118, 120 (e.g., continuously or discontinuously). In one example, the track 300 can extend along the perimeter 134 of each housing 118, 120 from one end of the hinge structure 170 to the other end of the hinge structure 170.

[0126] When the zip strips 202 are placed in the tracks 300 of each housing, the zip teeth 210 of each zip strip 202 can engage with each other to bind together and form the closing assembly 200. The closing assembly 200 can hold the first housing 118 and the second housing 120 in a closed configuration.

[0127] As Figure 5B shown, in some examples, a secondary closing assembly 260 can be included. In one example, the secondary closing assembly 260 can be a lining zip assembly to attach a lining or additional features along the interior 136 of the housing 118. The secondary closing assembly 260 can include a secondary zip strip 264 that selectively engages with a lining zip strip 266. The secondary zip strip 264 can engage with the lining zip strip along secondary mating features 262. The secondary zip strip 264 can be coupled to the zip strip 204 of the zip strip 202. For example, the secondary zip strip 264 can be stitched (e.g., at the stitch connection 212) to the zip strip 204. The secondary zip strip 264 can be positioned inside the zip strip 204. In some examples, the secondary zip strip 264 can be attached or engaged with the extrusion 208.

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

[0129] Regarding Figure 7 , another example of a luggage 1000 is shown. The luggage 1000 may include the same or similar features as those described above regarding the luggage 100. The luggage 1000 may include two or more housings, such as a first or top housing 1118 and a second or bottom housing 1120. The top housing 1118 and the bottom housing 1120 may be selectively coupled along a connection line 1122 by a closure assembly 1200. It should be understood that the housings 1118, 1120 may include features similar or identical to the housings 118 and 120 described elsewhere herein. The housings 1118, 1120 may be coupled along the sides by one or more discrete hinges 800. The hinges 800 may be placed along the outer surface or side 1138 of the luggage 1000. The luggage 1000 may include a retractable towing handle 1126.

[0130] The hinge 800 may include a body 801 that defines a first end 802, a second end 804, and a connecting or intermediate portion 806 that extends between the first end 802 and the second end 802. Each of the first side 802 and the second side 804 may be rectangular in shape. The intermediate portion 806 may extend between or be attached to the first side 802 and the second side 804. The intermediate portion 806 may be made of a flexible and / or durable material.

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

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

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

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

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

[0136] The track 1300 may include an optional guiding feature or inner edge 1322 extending from the second flange 1308. The optional inner edge 1322 may assist in guiding the zipper tape 1202 through the track 1300 or protect the zipper tape 1202 from items stored in the luggage 1000. The track 1300 may include optional support fins or flanges 1332 that extend from the housing 1120 and attach to or engage the support member 1326. The support fins 1332 may extend between the support members 1326. The support fins 1332 may be continuous or discontinuous.

[0137] The track 1300 can define an access area 1194 to allow the zipper tape 1202 to be inserted into the gap 1330. The access area 1194 can be an opening in the track at or near the gap 1330. In one example, the access area 1194 is an example of a discontinuous track 1300 and can include an opening in the track formed by the ends of the track 1300 spaced apart by a break (e.g., 4-6 cm). For example, the access area 1194 can be defined between a first end 1350 of the track 1300 and a second end 1352 of the track 1300 spaced along the edge 1132. In one example, the access area 1194 is located on the interior 1136 of the housing 1120. In some examples, as described in more detail below, the hinge 800 can be attached or connected to the housing 1120 at the access area 1194. The housing 1120 can define an access hole 1196 at the access area 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 functions as the closure assembly 200 and the zipper tape 202, respectively. For example, the zipper tape 1202 can include a chain strip 1204 and an extrudate 1208. The chain strip 1204 can define or include mating features 1206 along an edge, such as zipper teeth or zipper coils. The extrudate 1208 can include retention features 1216 to selectively engage the track 1300. The retention features 1216 can be spaced apart from the mating features 1206. The retention features 1216 can include lugs or flanges 1218 or otherwise enlarged portions. The retention features 1216 can include a neck 1222 spaced apart from the lugs 1218. The retention features 1216 can include one or more ribs 1220 adjacent to the neck 1222, opposite and spaced apart from the lugs 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 chain strip 1204, the extrudate 1208, or both.

[0140] As Figure 8A and 9BAs shown, the zipper tape 1202 can be inserted into the track 1300 at the entry region 1194. For example, the second end 1272 of the tape 1202 can be inserted at the first end 1350 of the track 1300. The retaining feature 1216 can engage the track 1300. For example, the neck 1222 can be inserted between the first flange 1306 and the second flange 1308, such as in the gap 1330. The lug 1218 can be placed in the channel 1328. The zipper tape 1202 can be moved in the insertion direction 1340 until the zipper tape 1202 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 be aligned with the entry region 1294. For example, the zipper hole 1275 can be aligned with the entry hole 1196.

[0141] To secure the zipper tape 1202 to the track 1300 or hold it in the track 1300, the hinge 800 can include features to connect to the housing 1120 and the zipper tape 1202. The hinge 800 can include an attachment feature or anchor 810. For example, the anchor 810 can be an elongate feature extending from the hinge 800. The anchor 810 can extend from either or both of the first side 802 or the second side 804. In one example, the attachment feature 810 can include a shaft 813 with an enlarged end 816. The anchor 810 can be inserted through the entry hole 1196 to couple the hinge 800 to the housing 1120. The anchor 810 can be inserted through the zipper hole 1275 to secure the zipper tape 1202 to the track 1300 or the housing 1120. For example, the shaft 813 can be placed within the holes 1196, 1275 and the enlarged end 816 can extend through the holes 1196 and 1275. The hinge 800 can be attached to either or both of the housings 1180, 1200 before or after installing the closure assembly 1200 in the track 1300.

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

[0143] Reference Figure 10, in some examples, the housing 1120 can define an anchor or attachment feature 1810. For example, the anchor 1810 can extend from the housing 1120. In one example, the anchor 1810 extends from the inner surface 1136 of the housing 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 inner side 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 housing 1120 is shown. In some examples, at or near the corner region 1160, the features of the track 1300 can be arranged to improve the guidance of the zipper tape 1202 through the channel 1328. For example, the zipper tape 1202 can be received by the track 1300 in the channel 1328, where the second end 1272 faces the insertion direction 1340.

[0145] Continuing to refer 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, which means that the flange 1306 or 1308 can be or include multiple spaced-apart features or features that extend different distances from the housing 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 proximal 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 proximal 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 the resistance to passing through the corner region 1160. The leading edges 1366, 1388 can help guide the zipper tape 1202 through or back into the channel 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 channel 1328.
