[0073] The present application may disclose alternative configurations for attaching component parts, such as front pocket assemblies, panels, zippers, to luggage cases, and luggage cases having such components, particularly front pockets, attached thereto. For example, either the luggage case or the attachable component may include one or more frame attachment structures configured to mate with corresponding rim attachment structures on the other of the luggage case or the attachable component, in one embodiment by snap-fit ​​frame attachment structures.

[0074] The luggage case may include a body comprising two or more shells attached by hinges. The shells may define an opening. The opening may include an open space through the shell, a recess formed in the shell, or an open space formed in a recess in the shell. In any of these instances, a rim or edge extends around and defines a perimeter of the opening or recess.

[0075] In one embodiment, the attachable component is a front pocket for a luggage case. The front pocket can include two or more portions that are selectively joined by a closure assembly. For example, a top portion including a front panel and a bottom or back portion that can include an underlying panel of a relatively rigid or flexible material can be joined by the closure assembly. An interior volume of the pocket can be defined between the top and bottom portions. The top portion acts as a door or lid to allow access to the interior volume of the pocket. The front pocket, as an example component, can include a molded, e.g., extruded, frame that is coupled to one of the portions of the pocket. For example, the frame can be coupled to the bottom or back portion of the pocket. The frame can include a flexible or resiliently yielding material.

[0076] The attachable component, such as a pocket, can be coupled or engaged with the shell. The engagement can be a snap-fit ​​engagement. The snap-fit ​​engagement can be a coupling structure that couples two components together. One component can be a receiving structure, such as a rim coupling structure, and the other component can be an engaging structure, such as a frame coupling structure. The rim coupling structure can be configured to receive and hold the frame coupling structure with an interlocking interface. For example, the rim coupling structure can be a hook, holder, or grooved shape. The frame coupling structure can be a U-shaped clamp, clasp, or clip shape. Thus, the clip shape can couple or snap-fit ​​to the hook. In some embodiments, the snap-fit ​​engagement can include a resiliently deflecting mechanical interference to maintain the interlocking engagement and inhibit disengagement of the components. In some embodiments, the snap-fit ​​frame coupling structure can be used to couple the components together without requiring the use of another attachment feature, such as a fastener, adhesive, or the like. In some embodiments, another attachment feature can be used to complement the snap-fit ​​frame coupling structure and reduce the possibility of unintended separation of the components.

[0077] In some embodiments, the shell defines or includes a rim connection structure. For example, the rim connection structure is located adjacent the opening or recess, for example, formed in the rim in one embodiment, or formed near the rim, for example, within 0.5-4 cm of the rim. The rim connection structure is for engaging an attachable component (such as a pocket or closure assembly), for example, by a snap fit. The rim connection structure may extend continuously along the rim or edge, or may be located at one or more discrete locations along the rim or edge. The rim connection structure may be in the form of a hook, holder, or barb that extends from the rim or edge into or adjacent the opening. In some embodiments, the rim may define a side and a corner region of the opening. In such an example, the rim connection structure may include a first portion along at least a portion of the side and a second portion along at least a portion of the corner region.

[0078] The frame may include or define one or more frame connection structures that allow the pocket to be attachable or detachable to a corresponding rim connection structure on the shell. For example, the frame connection structures may be located adjacent to a periphery of the frame, such as formed at the periphery in one embodiment, or formed near the periphery, such as within 0.5-4 cm of the periphery. The frame connection structures are for engaging, such as by a snap fit, with a corresponding attachment structure on the shell, such as a rim connection structure. The frame connection structure may extend continuously along the periphery of the frame or may be located at one or more discrete locations along the periphery of the frame. The frame connection structure may be in the form of a U-shaped hook, clasp, or clip extending from the frame. A snap-fit ​​engagement may allow the front pocket or attachable component to be easily attached to or removed from the shell. In some embodiments, the frame may include sides and corners. In such examples, the frame connection structure may include a first portion along at least a portion of the side and a second portion along at least a portion of the corner area.

[0079] In some embodiments, the shell includes a frame attachment structure and the rim attachment structure may be defined by or attached to the front pocket. For example, the frame may be connectable to the rim or edge and the rim attachment structure may be defined by or connectable to the pocket assembly. In some embodiments, the corresponding frames defining the rim attachment structure and the frame attachment structure are each connected to the shell and the attachable component (e.g., the pocket or the closure mechanism), respectively.

[0080] In some embodiments, the attachable component may be a closure assembly, such as a zipper assembly for connecting or selectively accessing an interior volume between two shells of the luggage case. Thus, two or more shells, or shell portions, may define rim connection structures and the closure assembly may define a corresponding frame connection structure. The rim connection structures may be disposed along the periphery of the shells. The frame connection structures may connect to the rim connection structures to define a linear connection around the shells. In some embodiments, if the attachable component is damaged, it may be removed from the shells and replaced rather than replacing the entire luggage case.

[0081] In some embodiments, the frame connection structure, the rim connection structure, or both may be continuous structures that engage with each other. In some embodiments, the frame connection structure and the rim connection structure may be separate, discrete clips or segments that are positioned around the frame and rim, respectively, to properly align the appropriate engagement. In yet another example, one of the rim connection structure or the frame connection structure may be continuous, while the other of the rim connection structure or the frame connection structure includes discrete clips or segments for interconnecting. If the rim connection structure or the frame connection structure are discrete clips or segments, in one embodiment there may be four of each structure, one positioned on each side of the rim and / or frame.

[0082] By allowing various components, such as the front pocket assembly, to be attached to the shell by a snap-fit ​​engagement, the difficulty of attaching the components can be reduced. Furthermore, the snap-fit ​​engagement allows the customer to select or customize different combinations and styles of components attached to the shell. For example, larger or smaller pockets can be selected. Different colors, textures, fabrics, or other aesthetic combinations and selections can be made.

[0083] FIG. 1 illustrates a front perspective view of an exemplary luggage case 100 including an exemplary pocket assembly 200 in a closed configuration. FIG. 2 illustrates an exploded view of the exemplary front pocket assembly 200 separated from the luggage case 100. The luggage case 100 can include a rim connection structure 306 that engages with a corresponding frame connection structure 250 of the pocket assembly 200 to selectively attach or snap-fit ​​the pocket assembly 200 to the luggage case 100.

In some embodiments, the luggage case 100 can include a frame connection structure 250 that can engage with the pocket assembly 200 including the rim connection structure 306 or other removable components.

[0084] Luggage case 100 may be or may be referred to as a luggage item, bag, trolley, etc. In one embodiment, luggage case 100 may be an upright, hard-sided case, such as a wheeled luggage case. In other embodiments, luggage item 100 may be many types of luggage, including soft-sided wheeled cases with molded frames and interior shells, mixed (e.g., including soft and rigid panels) luggage cases, containers, etc. Luggage case 100 may include two or more shells 102, 104 and multiple panels that define an interior storage volume 130 for transporting personal belongings.

[0085] The luggage case 100 may include a front or top shell 102 and a back or bottom shell 104. The luggage case 100 may include one or more sides or panels. For example, the luggage case 100 may include a front panel 106 and an opposing back panel 108, a top panel 110 and a bottom panel 112, and opposing left and right panels 114 and 116. The front shell 102 and the back shell 104 may be joined together to define an interior storage volume 130. The luggage case 100 may be moved between a closed configuration in which edges 300 of the two or more shells 102, 104 are positioned adjacent to one another, and an open configuration that provides access to the interior storage volume 130. The luggage case 100 may be selectively opened and closed by a closure assembly 122, such as a zipper, latch, or similar assembly. While reference is made to either the front shell 102 or the back shell 104, it is understood that either shell may include the same or similar features. The shells 102, 104 may also be joined by a hinge along one side or panel, such as the left side 114.

[0086] The shells 102, 104 may be hard-sided, soft-sided, or mixed-sided shells. The shells 102, 104 may be made entirely or partially of molded polymers. The shells 102, 104 may be formed by pressure molding, vacuum forming, or injection molding. The shells 102, 104 may be formed as a single unit having at least some of the characteristics of the shells described herein that are formed by molding. For example, a hard-sided luggage case 100 as shown in Figures 1 and 2 may be formed at least in part by a molding process. The soft-sided luggage case 100 may be made by molding all or a portion of the perimeter of the shells 102, 104 and connecting thereto the soft-sided outer portion and the desired frame members.

[0087] The external element can be connected to a molded portion of the luggage case 100. In some embodiments, the luggage item 100 can include one or more carrying handles 128 and / or a telescoping towing handle 126 extendable from a bezel in the back panel 108 of the luggage item 100. The telescoping towing handle 126 can extend outwardly from the bezel and retract into the bezel to allow a user to pull or tow the luggage item 100. The luggage item 100 can include one or more leg elements 148, such as wheels, casters, spinner assemblies, posts, etc., to enable the luggage item 100 to be supported or moved across a supporting surface, such as a floor, road, sidewalk, or ground.

The pocket assembly 200 can be received in or within an opening 120 defined by one of the shells 102, 104 of the luggage case 100. In some embodiments, the opening 120 can be an open space, such as a hole, formed through the shell in which it is located and can extend into an interior region of the shell, such as the interior storage volume 130 of the luggage case 100. In other embodiments, the opening 120 can be a recess or depression in a portion of the shell 102, 104 that does not expose an interior of the shell, such as the interior storage volume 130 of the luggage case 100. For example, if the opening is in the shape of a recess, the opening can define a bottom wall or floor of the opening 120. In one embodiment, the pocket assembly 200 is a front pocket assembly and the opening 120 is defined in the front or top shell 102. For example, the opening 120 can be defined in the front side or front panel 106.

[0089] The shell 102 may include an edge or rim 300 that extends around the opening 120. The rim 300 may be integrally formed with the shell 102. The rim 300 may include one or more sides 328. For example, the opening 120 may be rectangular and include four sides 328. The rim 300 may have a corner region 330 at an end of one of the sides 328 or between two or more of the sides 328. In one embodiment, the opening 120 is rectangular and the rim 300 includes four sides 328 and four corner regions 330.

[0090] The rim 300 may define or include a rim connection structure 306 that defines a portion of the snap-fit ​​engagement. The rim connection structure 306 may be a hook, barb, or curved holder. In some embodiments, the rim connection structure 306 is integrally formed with the rim 300. In some embodiments, the rim connection structure 306 is separate that is connected to or attached to a portion of the rim 300. The rim connection structure 306 may be defined along all or a portion of the rim 300. For example, the rim connection structure 306 is elongated in shape. The rim connection structure 306 is engageable with a corresponding frame connection structure 250 of the pocket assembly 200, such as by a snap fit as discussed herein. In some embodiments, the rim 300 may define more than one rim connection structure 306. For example, the rim connection structure 306 is a first rim connection structure 306, which in this example is located on the side 328 of the rim. In some embodiments, corner region 330 can optionally include a second connection structure, or corner connection structure 332, disposed between or adjacent the sides.

For example, the frame 240 can include one or more sides 248 and one or more corners 280 adjacent to or between the sides 248. In one embodiment, frame 240 corresponds to a rectangular pocket assembly 200 and includes at least four sides 248 and at least four corners 280 adjacent or between sides 248. In some embodiments, frame 240 may be cut from a larger block or strip and define a first edge 297 and a second edge 299 opposite first edge 297, as shown in FIG. 4. In some embodiments, frame 240 is continuous. In some embodiments, frame 240 may be discontinuous and segmented (e.g., into two or more frames or into multiple frames of different widths or thicknesses).

[0096] The frame 240 can include a base flange 241. The base flange 241 can define the frame 240 or can be the main body of the frame 240. The base flange 241 can extend the entire length of the frame 240, or a portion of the length of the frame 240. The base flange 241 can have a top 242 and a bottom 243 extending from the top 242. The base flange 241 can define or include an outer wall or surface 244. The base flange 241 can define or include an inner wall or surface 246 opposite the outer wall or surface 244. In some embodiments, the top 242 of the base flange 241 can include a tail or spine 247. The spine 247 can extend from the inner wall 246 of the top 242.

[0097] The base flange 241 may include or define a portion of the frame connection structure 250. The frame connection structure 250 may be a U-shaped clamp, a clasp, or a clip. The frame connection structure 250 may be defined along a portion of the frame 240, such as a side 248 of the frame 240. Thus, the frame connection structure 250 may be elongated in shape or extend along a portion of the side 248. In some embodiments, the frame 240 includes more than one set of the frame connection structures 250. A corner 280 of the frame 240 may optionally include or define a second set of frame connection structures 282 along at least a portion of the corner 280. For example, the frame connection structure 250 may be a first frame connection structure defined on the side 248, and a second, or corner, frame connection structure 282 may be disposed on a portion of the corner 280. The frame connection structures 250 at the sides 248 may be snap-fit ​​connection structures, and the frame connection structures 250 at the corners 280 do not have to be snap-fit ​​connection structures.

[0098] The base flange 241 can define or include a first frame connection structure or hitch structure 252. The base flange 241 can define or include a second frame connection structure or well portion 265. The hitch structure 252 and the well structure 265 can define a frame connection structure 250. In some embodiments, the frame connection structure 250 can be continuous or discontinuous along the frame. For example, the frame connection structure 250 can extend along one or more lengths of the frame 240, such as the side portion 248, to place the frame connection structure in discrete locations. In other embodiments, the frame connection structure 250 can be segmented along the frame 240 or can extend intermittently along the frame 240. In the embodiment shown in FIG. 3, the snap-fit ​​frame connection structure 250 extends along a majority of the periphery of the pocket assembly 200. The snap-fit ​​frame connection structure 250 is discontinuous. For example, they may be located at discrete locations or portions along the frame 240 of the pocket 200, such as along the sides 248. In one embodiment, as shown, the snap-fit ​​frame connection structures 250 extend along each side 248 of the pocket assembly 200, and in some embodiments may not be located at the corners 280 of the frame 240. The connection structures 282 at the corners 280 are not snap-fit ​​connections in this embodiment, but rather are aligned or abutting type connections as shown in FIG.

[0099] 3, 4, and 5, an example of an assembled pocket assembly 200 is shown. In some embodiments, a frame connection structure 250 can be connected to the pocket assembly 200. For example, a frame 240 can be connected to the pocket assembly 200. In some embodiments, the frame 240 can be connected to the top 202 or bottom 208 of the pocket assembly 200 along either of the perimeters 206, 212. In one embodiment, the frame 240 is attached to the bottom 208. For example, the base flange 241 can be disposed along a portion of the perimeter 212 of the bottom 208.

[0100] To attach the frame 240 to the pocket assembly 200, the rim 212 can be positioned against the inside 246 of the top 242 of the base flange 241. The rim can be positioned adjacent to or in contact with the spines 247. The closure assembly 218 can also be attached to the bottom 208 and / or the frame 240. For example, a portion of the second zipper strip 224 can be positioned against the outside 244 of the top 242. The second zipper strip 224, the frame 240, and the substrate 210 can be attached together by fasteners (rivets, bolts, snaps, etc.), adhesives, or stitching 232. The spines 247 can help guide the fastener, adhesive, or stitching 232 device when attaching the frame 240 to the substrate 210 or the second zipper strip 224. For example, the spines 247 can guide the legs of a sewing tool along a portion of the base flange 241. A first zipper strip 220 can similarly be attached to the top or front portion 202. For example, a portion of the first zipper strip 220 can be disposed along the perimeter edge 206 of the top portion and attached by fasteners, adhesive, or stitching 232.

[0101] In some embodiments, the pocket assembly 200 includes a binding 230. The binding 230 can be configured to cover or secure the connections of the pocket assembly 200. For example, the binding 230 can extend over and over the side of the perimeter 212 opposite the frame 240 to the second zipper strip 224. The binding 230 can also be attached to the components by fasteners, adhesives, or stitching 232. The top 202 and the first zipper strip 220 can also include a binding 230. The binding 230 can cover the components to hide the assembled components and / or protect the components from wear. In one embodiment, the binding 230 is an abrasion resistant fabric.

[0102] After assembly of the pocket assembly 200, the pocket assembly 200 defines a second or interior pocket storage volume 215 capable of receiving personal items or cargo. The second interior storage volume 215 may be made accessible by selectively opening and closing a closure assembly 218.

[0103] 4 and 5, the frame connection structure 250 of the frame 240 extends from or is defined by the base flange 241. As discussed herein, the frame connection structure 250 defines a J-shaped or U-shaped clip, clasp, or clamp shape and can engage or snap-fit ​​with a corresponding rim connection structure 306 of the luggage shell 102. The frame connection structure 250 and the rim connection structure 306 together can define a snap-fit ​​engagement structure. The frame connection structure 250 can include a hitch structure or first frame connection portion 252 and a well structure or second frame connection portion 265.

[0104] The hitch structure 252 can extend from the outer side 244 of the base flange 241. The hitch structure 252 can be a clip-type structure or an interlocking structure. For example, the hitch structure 252 can extend from the base flange 241 between the top 242 and the bottom 243. The hitch structure 252 can be bent, hook-shaped, or otherwise change direction longitudinally. The hitch structure 252 can be shaped like a clasp or clip. In some embodiments, the hitch structure 252 can be straight. The hitch structure 252 can include an arm or horizontal portion 254. In some embodiments, the arm portion 254 can extend at an angle or perpendicular to the base flange 241. A second portion or tongue 257 can extend from the arm portion 254. The tongue 257 can extend perpendicular to the arm portion 254. The tang 257 may extend parallel to or aligned with the base flange 241 adjacent the horizontal portion 254. The hitch structure 252 may define a void or recess 259. For example, the void 259 can be defined between the tang 257 and the base flange 241. The horizontal feature 254 may define the top of the void 259.

[0105] The second frame connection or well structure 265 can be defined by the base flange 241. The well structure 265 can be a J-shaped or U-shaped receiver shape. The base flange 241 defines the second frame connection 265 and can define a return or crown 268. For example, the second frame connection 265 can be a portion of the bottom 243 of the base flange 241. The crown 268 can define a change in direction of the base flange 241. The crown 268 can define an arched or curved shape. The base flange 241 can include a non-constrained wall or flange 271 extending from the crown 268. The non-constrained wall 271 can be parallel or aligned with the top 242 of the base flange 241. The non-constrained wall 271 can extend into or terminate at a tip 273. The tip 273 can be an angled end of the non-constrained wall 271. For example, the tip 273 may be angled or sloped away from the base flange 241. In some embodiments, the tip 273 may be omitted or replaced with a tip 273 that defines a peak or edge of the non-constraining wall 271. The second frame connector 265 may be spaced from the hitch structure 252 to define an open space or passageway 261. For example, the non-constraining wall 271 may be spaced from the tang 257. In one embodiment, the non-constraining wall 271 is spaced from the tang 257 by a distance of about 1 mm to 5 mm, although other distances are contemplated.

[0106] The well structure or second frame link 265, defined by the bottom 243 of the base flange 241, can define a slot or recess 276 therebetween. The crown 268 can define a bottom of the slot 276. The second frame link 265 and the hitch structure 252 can define an open space or passage 261, such as between the non-restraining wall 271 and the tang 257. The passage 261 can extend to the slot 276. In some embodiments, the distance from the tang 257 to the crown 268 can define a slot height 278.

[0107] 1-2 and 7A, the shell 102 may define an edge or rim 300. The edge 300 may be defined by the shell 102 and extend around a portion of the opening 120. The edge 300 may be a change in shape and orientation of the shell 102 around the opening 120. For example, the edge 300 may have an apex 302 that defines a transition from the shell 102 towards the opening 120.

[0108] The rim connection structure 306 can be connected to or formed on the shell 102. For example, the rim connection structure 306 can be connected along a portion of the rim or edge 300. For example, the rim connection structure 306 can be attached to or molded onto the rim 300. In some embodiments, the rim connection structure 306 is integrally molded with the rim 300. The rim connection structure 306 can define a portion of a snap-fit ​​structure. The rim connection structure 306 can be a hook, holder, or barb. For example, the rim connection structure 306 can be generally U-shaped or J-shaped. The shape or contour of the rim connection structure 306 can correspond to the shape or contour of the frame connection structure 250.

[0109] The rim connection structure 306 can include a first portion 308 and a second portion 312. The first portion 308 can extend from the edge 300. The second portion 312 can define a hook or a bend. The rim connection structure 306 can include an inner surface 316 facing or located toward the wall of the shell 102 and an outer surface 318 opposite the inner surface 316. In some embodiments, the rim connection structure 306 can be continuous along all or a portion of the rim 300. In some embodiments, the rim connection structure 306 is discontinuous or segmented. For example, the snap-fit ​​rim connection structure 306 is disposed along a side 328 of the rim 300 and is not formed to extend through the corner region 330. In some embodiments, the rim connection structure 306 is a first rim connection structure of a snap-fit ​​connection and the optional corner region 330 can define a second or corner rim connection structure 332. This may be an aligned connection or a contact connection rather than a snap-fit ​​connection. A cavity 304 may be defined between the rim connecting structure 306 and the wall of the shell 102 .

[0110] The first portion 308 can extend away from the body of the shell 102 from the apex 302. The first portion 308 can include a chamfer 310. The chamfer 310 can be a slanted wall or shape relative to the apex 302 or the shell 102. For example, the chamfer 310 can extend downwardly and inwardly from the apex 302. In some embodiments, the chamfer 310 can be curved and change direction further inward with its length relative to the apex 302. For example, the inner surface 316 of the chamfer 310 can be concave and / or the outer surface 318 of the chamfer 310 can be convex. In curved embodiments, the inner surface 316 can define a cam surface for the rim interlocking structure 306.

[0111] The second portion 312 can extend from the first portion 308, such as from the end of the chamfer 310. The second portion 312 can be U-shaped or hook-shaped. The second portion 312 can include an inner wall or flange 314. The inner wall 314 can extend from the first portion 308. For example, the inner wall 314 can extend from the chamfer 310. The inner wall 314 can be vertically aligned. In some embodiments, the inner wall 314 can be straight. For example, an inner surface 316 of the inner wall 314 and an outer surface 318 of the inner wall 314 can be parallel.

[0112] The second portion 312 can include an anchor or head portion 321. The head portion 321 can be shaped to have a greater width and thickness than the inner wall 314 or the rim 300. The head portion 321 can be curved or arc shaped. The head portion 321 can extend from the inner wall 314. For example, the head portion 321 can extend from the end of the inner wall 314 in a direction away from the apex 302. In some embodiments, the inner surface 316 of the head portion 321 can extend vertically and continuously aligned with the inner wall 314. The outer surface 318 of the head portion 321 can be curved. The outer surface 318 of the head portion 321 can extend upward toward the apex 302 and outward from the apex.

[0113] The second portion 308 can include a catch portion 324. The catch portion 324 can extend from the head portion 321. For example, the catch portion 324 can extend from the outside of the head portion 321. The catch portion 324 can be a lip, a detent, a hook, a notch, or a tang. The catch portion 324 can be spaced from the outer surface 318 of the vertical wall 314 to define a groove 326 therebetween. The distance from the catch portion 324 to the bottom of the head portion 321 defines a head height 325.

[0114] 6A-6D, an exemplary method of attachment or snap-fit ​​engagement of the frame connection structure 250 to a corresponding rim connection structure 306 is shown. A snap-fit ​​engagement can be a joint between two components that includes a receiving feature, such as the rim connection structure 306, that is configured to receive and hold a second structure, such as the frame connection structure 250. The snap-fit ​​engagement between the rim connection structure 306 and the frame connection structure 250 can structurally interengage or interlock two or more structures to connect the rim connection structure 306 and the frame connection structure 250. For example, as shown in FIG. 6D, the pocket assembly 200 can be selectively attached or snap-fit ​​to the shell 102 at the opening 120. In some embodiments, the frame connection structure 250 can include or have a characteristic of being elastically flexible to help maintain the connection between the rim connection structure 306 and the frame connection structure 250. In some embodiments, the frame connection structure 250 and the rim connection structure 306 can be engaged using another component, such as a fastener, rivet, adhesive, or the like. In some embodiments, no additional components are used to complement the snap-fit ​​engagement. While the rim 300 has been described as defining the rim connection structure 306 and the frame 240 as defining the frame connection structure 250, it should be understood that in some embodiments, the reverse may be true. For example, the rim or edge 300 may define or include the frame connection structure 250, and the frame 240 may include or define the rim connection structure 306. In some embodiments, the attachment may be a selective engagement that allows for both attachment and removal. In some embodiments, the attachment may be a one-way engagement that is not intended to be removed or separated.

[0115] Prior to attaching the frame connection structure 250 to the corresponding rim connection structure 306, the frame 240 or pocket assembly 200 can be positioned above the rim 300. The frame 240 can be moved from above the rim 300 into the recess 120 and positioned below the rim connection structure 306, as shown by arrow 370 in FIG. 6A. The frame connection structure 250 can be positioned below the second or hook portion 312 of the rim connection structure 306. For example, the second portion 312 can be positioned above the well structure 265 and the hitch structure 252. The head portion 321 can be positioned above the passage 261 between the well structure 265 and the hitch structure 252. The non-constraining wall 271 can be positioned below and toward the shell 102 relative to the inner wall 314. The hitch structure 252 can be positioned below the outer surface 318 or curved portion of the head portion 321. The base flange 241 of the frame 240 can be spaced from the second portion 312 that faces the shell 102. The base flange 241 and the remainder of the pocket assembly 200 can be at least partially positioned above the catch portion 324 and head portion 321 of the rim connection structure 306.

[0116] 6B, to attach the frame connection structure 250 to the rim connection structure 306, the frame 240 can be moved generally upwardly, as indicated by arrow 378. As described herein, the frame 240 can be a flexible or elastically deformable material. Thus, as the frame 240 moves upwardly, the second portion 312 of the rim connection structure 306 can be received in the well structure 265. The second portion can contact or engage the hitch structure 252.

[0117] For example, with reference to the hitch structure 252, the head portion 321 can be received in the passage 261 and contact the tongue 257. The head portion 321 can be wider than the passage 261. With reference to the hitch structure 252, as the frame 240 moves upward, the hitch structure 252 can correspondingly contact the outer surface 318 of the head portion 321 of the rim connecting structure 306. As the second portion 312 extends through the passage 261 and into the slot 276, the frame 240 bends or curves. For example, the head portion 321 can contact or engage the frame connecting structure 250, bending or deforming it outwardly to receive or conform to the rim connecting structure 306 or the rim 300. The vertical shape or tongue 257 can move along the head portion 321 and reach the catch portion 324. Thus, the hitch structure 252 can move upward and outward of the apex 302, as indicated by the arrow 380. The direction 380 of movement of hitch structure 252 may be a function of the movement of frame 240 as shown in direction 378 (e.g., upward as frame 240 moves upward) and the shape of head portion 321 (e.g., outward as head portion 321 increases in width). For example, the arcuate shape of head portion 321 helps slot 276 widen to receive head portion 321.

[0118] As the frame 240 moves upward, the well structure 265 can receive the second portion 312, for example, through the passageway 261 and into the slot 276. The unconstrained wall 271 can contact the inner surface 316 of the rim connecting structure 306. For example, the unconstrained wall 271 can move upward and outward as indicated by arrow 376, with the tip 273 contacting and traveling along the inner surface 316. The slope of the tip 273 can aid in the movement of the unconstrained wall 271 along the inner surface 316. For example, the angled shape of the tip 273 can guide the unconstrained wall 271 along the inner surface 316 from the chamfer 310 toward the apex 302. The chamfer 310 can direct the unconstrained wall 271 toward the shell 102 (e.g., into the cavity 304) and widen the slot 276 to receive the head 321. For example, the tip or edge 273 of the non-constraining wall 271 may engage the inner surface 316 of the chamfer 310 and flex outward (e.g., toward the shell 102) to widen the passageway 261 and allow the head 321 to pass therethrough and into the slot 276. In some embodiments, the chamfer 310 may be curved and act as a cam surface to flex the non-constraining wall 271 outward. For example, the non-constraining wall 271 may flex away from the base flange 241. In some embodiments, the tip 273 may have an angle that corresponds or matches the chamfer 310. The corresponding angle of the tip 273 may help guide the non-constraining wall 271 along the chamfer 310 or space the non-constraining wall 271 to widen the passageway 261 and the slot 276. In some embodiments, the non-constraining wall 271 may be biased toward the base flange 241 or may provide tension to the hitch structure 252 via the base flange 241. As a result, the hitch structure 252 may be pulled or placed under tension towards the rim 300 .

[0119] 6C, the frame 240 can continue to move upward, as indicated by arrow 378. The second portion 312 can be received by the well structure 265. The second portion can at least partially engage or contact the hitch structure 252. For example, the frame 240 can be positioned such that the crown 268 of the second frame connection portion 265 contacts the head portion 321. The head portion 321 can be inserted into the slot 276 and contact the bottom portion 243, such as the crown 268, of the base flange 241.

[0120] When the frame 240 is moved upward, the hitch structure 252 may pass, be above, or be on top of the catch portion 324. For example, when the head portion 321 is received in the slot 276, the catch portion 324 passes over the tongue 257, allowing the catch portion 324 to be received in the void 259. The distance from the catch portion 324 to the bottom of the head portion 321, i.e., the head height 325 shown in FIG. 6A, may be equal to or less than the distance from the tongue 257 to the crown 268, i.e., the slot height 278. Thus, the hitch structure 252 may extend above the catch portion 324 or contact the top of the catch portion. In some embodiments, the frame 240 is sufficiently resilient or deformable such that when the slot height 278 is equal to or less than the head height 325, the hitch structure 252 extends above the catch portion 324, allowing the head portion 321 to be received in the slot 276. In this position, the tongue 257 may be located above or adjacent to the groove 326. The catch 324 may be located directly below or adjacent to the gap 259.

[0121] The frame 240 or base flange 241 can retain its original shape and generate a resilient bias to return to its original position when it is bent or curved. As a result, the base flange 241 is under the bias to return to its original shape or near its original shape after it is bent or deformed to receive the second portion 312. As shown in FIG. 6C, the tip 273 can retain contact with the chamfer 310. The tip 273 and the non-constraining wall 271 can provide tension to the hitch structure 252 through the base flange 241. For example, the tension or deflection of the non-constraining wall 271 can be in the direction of arrow 382. The deflection or tension of the non-constraining wall 271 can promote deflection of the hitch structure 252 in an inward direction (e.g., direction 380). Thus, after the hitch structure 252 passes the head 321 or the top of the catch portion 324, it can move inwardly beyond the catch portion 324 or toward the shell 102 as shown by arrow 380. In some embodiments, the person installing the pocket assembly 200 can move the hitch structure 252 inwardly.

[0122] 6D illustrates the frame connection structure 250 with or engaged to the rim connection structure 306. For example, the exemplary pocket assembly 200 can be attached to the exemplary shell 102. From the position illustrated in FIG. 6C, the frame 240 can be moved downward, as indicated by arrow 384, to engage the frame connection structure 250 with the corresponding rim connection structure 306 to define a snap-fit ​​engagement structure. For example, the second portion 612 can be fully engageable with the well structure 265. The second portion 312 can interlock or engage with the hitch structure 552.

[0123] By moving the frame 240 or the base flange 241 downward, the hitch structure 252 can engage with the catch portion 324. The tongue 257 of the hitch structure 252 can be disposed in the groove 326. The catch portion 324 can be received in the gap 259. For example, the catch portion 324 can contact the tongue 257 or the horizontal feature 25. An interlocking structure can be defined by the engagement of the catch portion 324 and the tongue 257. Thus, the catch portion 324 and the tongue 257 can limit or restrain the frame 240 or the pocket assembly 200 from moving inwardly, outwardly, or downwardly relative to the rim 300.

[0124] The non-constraining wall 271 can move downward or toward the base flange 241 relative to the position of FIG. 6C. For example, the tip 273 can abut the chamfer 310 or the chamfer 310 and the inner wall 314. The non-constraining wall 271 can be in tension and exert a force on the inner wall 314. Thus, the second frame connection portion 265 defined by the non-constraining wall 271 and the crown 268 forming the slot 276 can engage or hold the head 321 and the inner wall 314. For example, the non-constraining wall 271 can be disposed against the inner surface 316 of the inner wall 314. Thus, the second frame connection portion 265 and the second portion 312 of the rim connection structure 306 can limit or restrain the frame 240 from moving inwardly, outwardly, or upwardly relative to the rim 300.

[0125] The frame 240 can also be moved so that the crown 268 can be moved away from the head 321. The distance between the crown 268 and the head 321 can correspond to the length or height of the tang 257, the catch 324, or the depth of the groove 326.

[0126] A snap-fit ​​engagement is defined when the corresponding rim connection structure 306 and frame connection structure 250 are engaged. Utilizing the corresponding frame connection structure 250 and rim connection structure 306 to attach the pocket assembly 200 to the shell 102 allows the pocket assembly 200 to be more easily attached to the shell 102 as opposed to sewing or other methods of fastening the pocket assembly 200 to the shell. For example, attachment of the pocket 200 to the shell 102 does not require a skilled worker or many tools. Furthermore, since the shell 102 and the pocket assembly 200 are separately assembleable, either part can be manufactured separately. For example, the shell 102 or the pocket assembly 200 can be finished or prepared for installation independently of one another. In some embodiments, one of the parts can be shipped or received at the same location and the other part can be assembled or manufactured at the same location.

[0127] Additionally, although the pocket assembly 200 has been described as being attached to the shell 102, it will be appreciated that in some embodiments, the pocket assembly 200 may be removed from the shell 102 as well. Thus, the frame attachment structure 250 and corresponding rim attachment structure 306 may be replaced in the event that the shell 102 or the pocket assembly 200 becomes damaged.

[0128] Although described with respect to pocket assembly 200, it will be understood that other parts, such as a handle (e.g., handle 128 or handle 126), a closure assembly (e.g., closure assembly 122), wheels (e.g., wheels 148), or other components of the luggage case may similarly be attached and detached via corresponding frame connection structures 250 and rim connection structures 306.

[0129] Figures 7A, 7B and 8 show the engagement of an optional embodiment corner region 330 of the rim 300 with an optional embodiment corner 280 of the frame 240. Figure 7A shows the corner region 330 of the rim 300 with the frame 240 unattached. Figure 7B shows the corner region of the rim 300 of Figure 7A with the corner of the frame 240 in place after being attached to the rim 300. Figure 8 is a cross-sectional view of the engagement between a corner rim attachment structure 332 of the rim 300 and a corner frame attachment structure 282 of a corresponding corner 280 of the frame 240.

[0130] The frame connection structures 250 may be continuous or discontinuous along the frame 240. For example, the frame 240 may include at least two frame connection structures 250 defined along a side 248 of the frame 240. The frame 240 may define a corner portion 280 including a corner frame connection structure 282 disposed between the at least two frame connection structures 250.

[0131] The rim connection structures 306 may be continuous or discontinuous along the rim 300. For example, the rim 300 may include at least two rim connection structures 306 along a side 328 of the rim 300. The rim 300 may include a corner region 330 between the at least two rim connection structures 306, the corner region 330 including a corner rim connection structure 332.

[0132] The frame 240 at the corner 280 may similarly include a base flange 241. The frame connection structure 282 at the corner 280 of the frame 240 may be similar to the frame connection structure 250 at the side 248, as shown in FIG. 8. For example, the frame connection structure 282 may include a hitch structure 252 including a horizontal structure 254 and a tang 257. The base flange 241 may be absent the bottom portion 243 at the corner 280. For example, the corner frame connection structure 282 may terminate at a second free end 287 spaced apart from the horizontal structure 254. The second free end 287 and the tang 257 may define a corresponding protrusion. The corner frame connection structure 282 may extend below the horizontal structure, similar to the tang 257. In some embodiments, corner frame connection structure 282 of corner portion 280 can be formed by cutting or removing bottom portion 243 or second frame connection portion 265 along a portion of frame 240, such as a distance from hitch structure 252 corresponding to second free end 287. Thus, the same die or extrusion process can be used to form the entire frame 240. Corner portion 280 can then be defined by removing material from frame 240 (e.g., second frame connection portion 265).

[0133] The corner region 330 of the rim 300 may include a corner rim connection structure 332 similar to the side portion 328 of the rim 300. For example, the corner rim connection structure 332 may include a first portion 308. The corner rim connection structure 332 may include a second portion 312 extending from the first portion 308. The second portion 312 may include an inner wall 314. The corner rim connection structure 332 may include a corner catching portion 333 spaced apart from the inner wall 314. A second, or corner, groove 339 may be defined between the corner catching portion 333 and the inner wall 314. The corner rim connection structure 332 may include a head 334 extending from the inner wall 314. However, the head 341 of the corner rim connection structure 332 may have a greater width than the head portion 321 of the side portion 328. 7A, the distance from the outer surface 318 of the inner wall 314 to the corner catch 333 may be greater than the distance from the outer surface 318 of the inner wall 314 to the catch 324. Similarly, the width of the corner groove 336 may be greater than the width of the groove 326 along the side 328.

[0134] When assembled, the corner frame connection structure 282 of the corner portion 280 of the frame 240 can be received and supported by the corner rim connection structure 332 of the corner region 330 of the rim 300. For example, the hitch structure 252 and the corner second frame connection structure 282 can be received in a groove 339 of the rim connection structure 332. The corner catch portion 333 can contact the inner side 246 of the base flange 241. The hitch structure 252, such as the tang 257, can contact the outer surface 318 of the inner wall 314.

[0135] The corners 280 are utilized to allow the frame 240 and the corner regions 330 of the rim 300 to engage without binding or warping at the corners 280 or the corner regions 330. In some embodiments, the corner frame connection structure 282 of the frame 240 can be received by the corner rim connection structure 332 of the rim 300 prior to engagement of the corresponding frame connection structure 250 and the rim connection structure 306. For example, the hitch structure 252 and the second frame connection structure 285 at the corner can be positioned in the groove 339 to bend or curve the frame 240 to allow attachment of the corresponding frame connection structure 250 and the rim connection structure 306. In some embodiments, the corner frame connection structure 282 of the frame 240 can be engaged by the corner rim connection structure 332 of the rim 300 after engagement of the corresponding frame connection structure 250 and the rim connection structure 306. For example, after the corresponding frame connection structure 250 and rim connection structure 306 are attached, the frame 240 can be bent or deformed to position the hitch structure 252 and second corner frame connection structure 285 within the corner groove 336.

[0136] 7B, in some embodiments, the rim 300 or rim attachment structure 306 may further include an alignment structure or rib 345. The rib 345 may be a structure that defines the rim attachment structure with an increased width or length. The rib 345 may extend from the second portion 312, such as the head portion 321 or the catch portion 324. The rib 345 may extend to a location below the head 321. For example, the rib 345 may have a height greater than the head height 325. The rib 345 may extend from the catch portion 324 to or beyond the inner wall 314. For example, the rib 345 may be located directly below the head portion 321 and have a width greater than the head portion 321.

[0137] In some embodiments, as shown in FIG. 7A , the rib 345 can be positioned adjacent the corner region 330. The rib 345 can be positioned to contact an edge of the frame connection structure 250, such as the well structure 265 defined by the bottom 243 of the base flange 241. For example, the rib 345 can contact the crown 268 or the unconstrained wall 271. The rib 345 can reinforce the edge of the side 248. The rib 345 can prevent or limit movement of the frame 240 or the pocket assembly 200 relative to the rim connection structure 306 or the shell 102. For example, the rib 345 can prevent or limit movement of the side 248 of the frame 240 into the corner region 330 of the rim 300. Thus, when the frame 240 or frame connection structure 250 is attached to the rim 300 or rim connection structure 306, the rib 345 can limit movement of the frame 240 or the pocket assembly 200 relative to the rim 300.

[0138] As shown in FIG. 9, in some embodiments, the shell 102 including the rim 300 can be formed by various molding methods. For example, the shell 102 can be formed by press molding, vacuum forming, or injection molding. The molding process can include at least two corresponding molds 406 and 415. The first mold piece 406 can define a mold surface 408. The second mold piece 415 can define a corresponding surface 417. During molding, the material of the shell 102 is placed under pressure and configured to have a shape corresponding to the mold pieces 406, 415. For example, the mold surfaces 408, 417 can define the rim 300 including the first portion or the second portion. Where there is an open space, such as the opening 120, excess material 402 can be formed during molding. Thus, the excess material 402 can be cut and removed along a line 404 to define the shell 102 including the rim 300.

[0139] Any of the features, components, and / or parts shown in any of Figures 1-9, including their arrangements and configurations, alone or in any combination, may be included in any other embodiment of the device, features, components, and parts shown in the other figures described herein. Similarly, any of the features, components, and / or parts shown and described with reference to the other figures, including their arrangements and configurations, alone or in any combination, may be included in the embodiment of the device, features, components, and parts shown in Figures 1-9.

[0140] 10A-10C illustrate another embodiment of a snap-fit ​​engagement structure of the pocket assembly 200 to the shell 102. For example, the snap-fit ​​engagement may be between a frame connection structure 550 and a rim connection structure 606. The frame connection structure 550 may be defined by the frame 540 and may include a shape similar or similar to the frame 240 described herein. For example, the frame 540 may be a flexible or resilient material and may include one or more sides and one or more corners. The rim connection structure 606 may be defined by or connected to an edge or rim 600 and may include a shape similar or identical to the rim 300 described herein. For example, the rim 600 may be defined by the shell 102 and extend around a portion of the opening 120 defined in the shell 102.

[0141] The frame connection structure 550 and the rim connection structure 606 can be engaged by moving either the frame connection structure 550 or the rim connection feature 606 in one direction relative to the other. For example, as shown in Figure 10B, the frame connection structure 550 can receive or connect to the rim connection structure 606 by moving the frame 540 in the direction of arrow 650 relative to the rim connection structure 606. In this embodiment, the frame 540 can be positioned above or over the rim connection structure 606 prior to engagement.

[0142] Frame 540 may include a base flange 541 that defines a body of frame 540. Base flange 541 may include an apex 542 and a bottom 543. Apex 542 may include a tail or spine similar to spine 247.

[0143] 10A, the frame connection structure 550 may be similar to the frame connection structure 250 described herein. For example, the frame connection structure 550 may be a U-shaped clasp, clip, or clamp structure. The frame connection structure 550 may include a first portion or hitch structure 552. The hitch structure 552 may extend from the base flange 541. The frame connection structure may include a second portion or well structure 565. The second portion 565 may be defined by the bottom 543 of the base flange 541.

[0144] The hitch structure 552 can include an arm portion 554 extending from the base flange 241. The hitch structure 552 can include a tang 557 extending from the arm portion 554. The tang 557 can be oriented vertically or in the same direction as the base flange 541. The tang 557 can terminate in a tang end 558. The tang end 558 can be oriented at an angle or slope toward the base flange 541 or the arm portion 554. The tang 557 can be spaced from the base flange 541, such as the bottom portion 543, and define a gap or slot 559.

[0145] Bottom 543 can define a well structure 565. Bottom 543 or well structure 565 can include a non-constraining wall 571. Base flange 541 includes a non-constraining wall 571 that defines a tip 573. In this embodiment, tip 573 includes a return shape that extends at an acute angle to non-constraining wall 571 at its terminal end.

[0146] The hitch structure 552 and the well structure 565 can be spaced apart to define a passage 575. For example, the tip 573 can be disposed adjacent to or spaced apart from the tang 557 to define a passage or open space 575 between the tang 557 and the unconstrained wall 571. A slot 559 can be defined between the hitch structure 552 and the well structure 565. For example, the slot 559 can be at least partially defined between the tang 557 and the unconstrained wall 571. The passage 575 can extend into the slot 559.

[0147] The frame connection structure 606 can be connected to or defined by the rim 600. The rim connection structure 606 can be a holder or hook shaped. The rim connection structure 606 can include a first portion 608 and a second portion 612. In some embodiments, the second portion 612 can define a hook or holder shape.

[0148] The first portion 608 can extend from the edge or rim 600. For example, the first portion 608 can include a chamfer 610 that extends from the shell 102. The chamfer 610 can extend at an angle, such as downwardly and inwardly, relative to the shell 102.

[0149] The second portion 612 can extend from or be connected to the first portion 608. For example, the second portion 612 can include an inner wall 614 extending from the chamfer 610. The second portion 612 can include a barb 621 extending from the inner wall 614 to define a hook or J-shape. For example, the barb 621 can be curved upwardly.

[0150] The second portion 612 can include a head portion 624 that defines an enlargement of the rim connection structure 606. The head portion 624 can extend from the return 621. The head portion 624 can include a first end or top end 626. The top end 626 can be angled. The top end 626 can be inclined toward the rim 600. The head portion 624 can include a second end or bottom end 628 opposite the first end 626. The bottom end 628 can be angled or inclined. For example, the bottom end 628 can be inclined toward the return 621 and define a notch or catch 630. The second portion 612 can define a groove 632. The groove 632 can be defined between the head portion 624 and the inner wall 614.

[0151] As discussed herein and shown in FIGS. 10A-10C, the frame 540 may be coupled to or defined by the pocket assembly 200. The pocket assembly 200 may be attachable to the shell 102 by a snap-fit ​​engagement defined by engagement of the frame attachment structure 550 and the rim attachment structure 606. For example, the second portion 612 may be received or engaged in the well structure 565 and the hitch structure 552. The snap-fit ​​engagement may be achieved by moving the frame 540 in a single direction, such as direction 650 in FIG. 10B, to couple the structures together. Thus, the snap-fit ​​engagement may allow for quick and easy attachment of the front pocket assembly 200 or other attachable component to the shell 102.

[0152] 10A , the frame 540 can be positioned above or adjacent the rim connection structure 606 of the rim 600 prior to engagement of the frame connection structure 550 and the rim connection structure 606. For example, the tip 573 can be positioned above the head portion 624.

[0153] 10B, frame 540 or pocket assembly 200 may be lowered or moved downward, as indicated by arrow 650, to engage rim connection structure 606. Frame 540 or base flange 541 may resiliently flex during contact with rim connection structure 606. Hitch structure 552 and / or well structure 565 may contact and flex second portion 612 to receive second portion 612 in passageway 575. For example, tang 557 may contact head 624 at top end 626 and flex into or toward groove 632 to expand passageway 575.

[0154] Additionally or alternatively, well structure 565 can contact head 624 and widen passageway 575 and / or slot 559 to receive head 624. For example, angled tip 573 can bias non-constraining wall 571 to help widen passageway 575 and / or slot 559, such as in direction 652. Either hitch structure 552 or well structure 565, or both, can create a tension or biasing force against second portion 612 or head 624.

[0155] 10C illustrates an example of a snap-fit ​​engagement defined by rim connection structure 606 and frame engagement structure 550. Compared to FIG. 10B, frame 540 may be positioned further downward, in the direction indicated by arrow 650. Upon snap-fit ​​engagement, hitch structure 552 and / or well structure 565 may retain second portion 612. For example, hitch structure 552 and well structure 565 may retain or engage head portion 624 within slot 559.

[0156] With reference to the hitch structure 552, as the frame 540 or base flange 541 moves downward, the hitch structure 552 can bias towards the well structure 565. In some embodiments, the angle of the tang end 558 can correspond to the profile of the 4-lobe 621 to aid in engagement of the hitch structure 552 with the second portion 612.

[0157] Referring to well structure 565, as frame 540 moves downward, well structure 565 can bias toward hitch structure 552 as shown by arrow 656. Well structure 565 can receive or snap-fit ​​second portion 612. For example, tip 573 can pass bottom end 628 and be received within catch 630. Tip 573 can limit or prevent head from dislodging downward, such as via passage 575. In some embodiments, tang 557 can flex into groove 632 or along barb 621 to provide clearance for tip 573 to extend beyond bottom edge 628.

[0158] Any of the features, components, and / or parts, including their arrangements and configurations, shown in any of Figures 10A-10C may be included, alone or in any combination, in any other embodiment of the device, features, components, and parts shown in any other figure described herein. Similarly, any of the features, components, and / or parts, including their arrangements and configurations, shown and described with reference to the other figures may be included, alone or in any combination, in the embodiment of the device, features, components, and parts shown in Figures 10A-10C.

[0159] 11A-11C illustrate another embodiment of a snap-fit ​​engagement structure of the pocket assembly 200 to the shell 102. For example, the snap-fit ​​engagement may be between a frame attachment structure 750 and a rim attachment structure 806. The frame attachment structure 750 may be defined by the frame 740 and may include a shape similar or similar to the frame 240 or the frame 540 described herein. The rim attachment structure 806 may be defined by or connected to the edge or rim 600 and may include a shape similar or identical to the rim 300 described herein. For example, the rim 800 may be defined by the shell 10 and extend around the opening 120.

[0160] The frame 740 can include a base flange 741 that defines a body of the frame 740. The base flange 741 can include a top portion 742 and a bottom portion 743. The frame connection structure 750 can be defined by the base flange 741 and can be connected to the base flange. The frame connection structure 750 can be similar to the frame connection structure 250 or the frame connection structure 550 described herein. For example, the frame connection structure 750 can be a U-shaped clasp, clip, or clamp structure. The frame connection structure 750 in this example can have a rounded or curved shape and can include an oval or oval end of the clasp, hook, clip, or clamp structure. The frame connection structure 750 can include a first portion or hitch structure 752. The hitch structure 752 can extend from the base flange 741. The frame connection structure 750 can include a second portion or well structure 765 defined by the bottom portion 743 of the base flange 741.

[0161] The hitch structure 752 may include a horizontal or arm portion 754 extending from the base flange 741. The hitch structure 752 may include a tang 757 extending from the arm portion 754. The tang 757 may terminate in a tang end 758. The tang end 758 may be angled or sloped toward or away from the base flange 741 or arm portion 754.

[0162] Well structure 765 may be hook-shaped or curved. Well structure 765 may include a non-constraining wall 771. Non-constraining wall 771 may be curved (e.g., bowed) or angled relative to top 742. Non-constraining wall 771 may extend to a tip curve or tip 773 that defines a return shape at the end of bottom 743 of base flange 741.

[0163] The hitch structure 752 and the well structure 765 can be spaced apart to define a passage 775. For example, the tip 773 can be located adjacent to the tang 757 or spaced apart from the tang. A slot 759 can be defined between the hitch structure 772 and the well structure 765. For example, the slot 759 can be defined at least partially between the tang 757 and the unconstrained wall 771. The passage 775 can extend into the slot or void 759.

[0164] The rim connection structure 806 may be similar to the frame connection structure 306 or the frame connection structure 606. For example, the rim connection structure 806 may extend along the rim or edge 800. The rim connection structure 806 may be in the shape of a holder or hook. The rim connection structure 806 may include a first portion 808 and a second portion 812. The first portion 808 may include a chamfer 810 extending from the rim 800 or shell 102 and extending at an angle relative to the shell 102. The second portion 812 may extend from or be connected to the first portion 808. For example, the second portion 812 may include an inner wall 814 extending from the chamfer 810. The second portion 812 may include a barb 821 that defines a hook, a curved body, or a J-shape extending from the inner wall 814. In some embodiments, the second portion 812 may define a hook-shaped shape.

[0165] The second portion 812 can include a head portion 824 that defines an enlarged or larger portion of the rim connection structure 806. The head portion 824 can extend from the barb 821. The head portion 824 can have a curved shape (e.g., oval or oval). The head portion 824 can include a first end or top end 826 and a second end or bottom end 828 opposite the first end 826. The top end 826 and / or the bottom end 828 can be angled or sloped. A curved surface 830 can extend between the top end 826 and the bottom end 828. The curved surface 830 can be located on the opposite side of the shell 102 from the head portion 824. The second portion 812 can define a groove 836 between the head portion 824 and the inner wall 814.

[0166] As discussed herein and shown in Figures 11A-11C, the frame 740 may be coupled to or defined by the pocket assembly 200. The pocket assembly 200 may be attached to the shell 102 by a snap-fit ​​engagement of the frame attachment structure 750 and the rim attachment structure 806. The snap-fit ​​engagement may be achieved by moving the frame 740 in a single direction, such as the direction 850 shown in Figure 11B, to couple the structures together. Thus, the snap-fit ​​engagement allows for quick and easy coupling of the front pocket assembly 200 or other attachable component to the shell 102.

[0167] As shown in FIG. 11A, the frame 740 may be positioned above or adjacent to the rim connection structure 806 of the rim 800 prior to engaging the frame connection structure 750 and the rim connection structure 806 .

[0168] In FIG. 11B, the frame 740 or pocket assembly 200 can be moved as shown by arrow 850 to engage the rim connection structure 806. When the frame 740 or base flange 741 contacts the rim connection structure 806, the frame 740 or base flange 741 can resiliently flex. The hitch structure 752 and / or well structure 765 can contact and flex the second portion 812 to receive the second portion 812 in the passageway 775. For example, the tongue 757 can contact and flex the head portion 824 to move into or toward the groove 836 and expand the passageway 775. The tongue 757 can be resiliently biased toward the head portion 824 to maintain contact with the head portion 824. Similarly, or alternatively, the well structure 765 can contact the head portion 824. For example, the tip or curved end 773 can contact the apex end 826 and flex outward, such as in direction 852. The flexing may widen the passageway 775 and / or slot 759 to receive the head 824 by moving the non-constraining wall 771 away from the head 824. The curved surface 830 of the head 834 may guide the tip 773 and the non-constraining wall 771 in the direction 852 to widen the passageway 775 or slot 759 (e.g., define clearance) to allow the head 824 to enter the slot 759.

[0169] Figure 11C illustrates an example of a snap-fit ​​engagement defined by rim connection structure 806 and frame engagement structure 750. Compared to Figure 11B, frame 740 may be positioned further downward in the direction indicated by arrow 850. Upon snap-fit ​​engagement, hitch structure 752 and well structure 765 may hold or engage second portion 812, such as head portion 824.

[0170] Referring to the hitch structure 752, as the frame 740 or base flange 741 moves downward, the hitch structure 752 can bias toward the well structure 765. Thus, the hitch structure 752 can maintain contact with the head 824. In some embodiments, the angle or slope of the tang end 758 can correspond to the profile of the barb 821 to facilitate engagement of the hitch structure 752 with the second portion 812.

[0171] With reference to well structure 765, non-constraining wall 771 may be biased in direction 856 (e.g., toward shell 102). For example, as frame 740 moves downward, tip 773 and non-constraining wall 771 may continue to bottom end 828 and be received in catch 834. Tip 773 may limit or prevent head portion from being removed downward, such as via passage 775. Thus, a snap-fit ​​engagement between frame connection structure 750 and rim connection structure 806 may be defined.

[0172] Any of the features, components, and / or parts shown in any of Figures 10A-10C, including their arrangements and configurations, alone or in any combination, may be included in any other embodiment of the device, features, components, and parts shown in other Figures described herein. Similarly, any of the features, components, and / or parts shown and described with reference to other Figures, including their arrangements and configurations, alone or in any combination, may be included in the embodiment of the device, features, components, and parts shown in Figures 10A-10C.

[0173] By allowing various components, such as the front pocket assembly 200, to be attached to the shells 102, 104 through a snap-fit ​​engagement, the difficulty and time required to attach the components to the luggage case 100 can be reduced. Furthermore, the snap-fit ​​engagement may allow a customer to select or customize different combinations and styles of components that are attached to the shell. For example, larger or smaller pockets can be selected. In some embodiments, different combinations and selections of colors, textures, fabrics, or other aesthetic features can be made.

[0174] With reference to the above examples of rim and frame connection features, the rim connection structure (306, 606, 806) may include at least two discrete rim connection structures disposed at different locations along at least a portion of one of the edges (300, 600, 800) or pocket assembly (200), and the frame connection structure (250, 282, 550, 750) includes at least two discrete frame connection structures disposed at different locations along at least a corresponding location of the other of the edges (300, 600, 800) or pocket assembly (200). When engaged with each other, the corresponding discrete rim connection structures and frame connection structures form a snap-fit ​​connection of the pocket assembly 200 to the edges (300, 600, 800) of the luggage case 100.

[0175] Continuing with reference to the above embodiments, in a further embodiment, the opening or recess (120) of the luggage case 100 may define at least four sides and the pocket assembly (200) may define at least four sides. A discrete rim coupling structure (306, 606, 806) may be disposed on each of the at least four sides of one of the openings or recesses (120) or on each of the at least four sides of the pocket assembly (200). A discrete frame coupling structure 250, 282, 550, 750 may be disposed on each of the at least four sides of the other of the openings or recesses (120) or on each of the at least four sides of the pocket assembly 200. When engaged with each other, the corresponding discrete rim coupling structures and frame coupling structures form a snap-fit ​​connection of the pocket assembly 200 to the edges 300, 600, 800 of the luggage case 100.

[0176] 12-15B, another embodiment of a luggage case 100 includes a shell 102 including a rim connection structure 1600 for engaging a corresponding frame connection structure 1516 of an additional component. In the embodiment shown in FIGS. 12-15B, the additional component may be a closure assembly 1500, such as a zipper. In this embodiment, the shell 102 may include an opening 120 that defines an interior storage volume. An edge or rim 300 may extend around the opening 120. In some embodiments, the rim 300 may extend around a perimeter of the shell 102. The closure assembly 1500 may be attachable and detachable to the rim connection structure 1600 of the shell 102.

[0177] In this embodiment, the closure assembly 1500 can be externally attached to a rim connection structure 1600. In this embodiment, the rim connection structure 1600 can be formed along at least a portion of the length of the edge or rim 300 of the shell 102, and in one embodiment, the rim connection structure 1600 can extend from the edge or rim 300 of the shell 102. The rim connection structure 1600 can extend outwardly from a base feature 1624 that is disposed along the interior surface 1136 of the shell 102. In some embodiments, the rim connection structure 1600 can extend in two directions, such as in opposite directions, to form anchors 1608 for attaching the closure assembly 1500 to the shell 102.

[0178] The closure assembly 1500 of this example may also be referred to as a snap-fit ​​closure assembly 1500. The closure assembly 1500 may engage the rim connection structure 1600 by a snap-fit ​​engagement. The closure assembly 1500 may include two zipper strips 1502 selectively engageable along the line of connection 122. Each zipper strip 1502 may include interengaging elements 1506 (such as zipper teeth 1510 or zipper coils), a zipper tape 1504, and a frame connection structure 1516. The interengaging elements 1506 may extend along at least a portion of the length of the inner edge 1512 of the zipper tape 1504.

[0179] The frame connection structure may include a base flange 1517 that defines a portion of the frame connection structure 1516 that is attached to or in contact with the zipper tape 1504. The frame connection structure 1516 may include a first frame connection structure 1518. The frame connection structure may include a second frame connection structure 1520 that extends along at least a portion of the length of the zipper strip 1502. The frame connection structure 1516 and / or the first frame connection structure 1516 or the second frame connection structure 1520 may be continuous or segmented. The base flange 1517 may have an inner surface 1532 and an outer surface 1534. Either the inner surface 1532 or the outer surface 1534 may be attached to the zipper tape 1504 along the corresponding outer surface 1532 or inner surface 1534 of the zipper tape 1504. The frame connection structure 1516 may be sewn, glued, molded, or otherwise attached to the zipper tape 1504.

[0180] As shown in FIGS. 13-15B, the second frame connection structure 1520 can extend from a surface of the base flange 1517. In one embodiment, the second frame connection structure 1520 extends from an inner surface 1532 of the base flange 1517 and flares away from the inner edge 1512. The second frame connection structure 1520 can include a catch feature that engages a feature of the rim connection structure 1600. The second frame connection structure 1520 can be flexible or rigid. The second frame connection structure 1520 can have a recess 1522 between the catch feature 1524 and the first frame connection structure 1518 to retain a portion of the rim connection structure 1600. A neck 1526 can be defined between the catch feature 1524 and the first frame connection structure 1518. The catch feature 1524 can be a hook, a detent, or a flange in one embodiment. The catch feature 1524 can be spaced apart from the first frame connection structure 1518 to define a gap 1530. The gap 1530 can define an entrance to the recess 1522. The recess 1522 can receive a portion of the rim connection structure 1600 and the catch feature 1524 can engage at or around another portion of the rim connection structure 1600.

[0181] 12, the frame connection structure 1516 can optionally include a groove 1540. The optional groove 1540 can be defined by a notch 1544 formed in the frame connection structure 1516. The groove 1540 can provide additional flexibility to the frame connection structure 1516. In areas where the groove 1540 is formed, such as around corners of the shell 102, the additional flexibility can facilitate attachment and detachment of the zipper strip 1502 from the shell 102. The inclusion of the groove 1540 can allow the frame connection structure 1516 to be made of a relatively stiffer material, resulting in a more secure attachment of the zipper strip 1502 to the shell 102.

[0182] The rim connection structure 1600 can extend along all or a portion of the rim 300 of the luggage case shell 102 and can be located inside the edge 300. The rim connection structure 1600 can be spaced apart from the rim 300 or defined along at least a portion of the length of the rim. The rim connection structure 1600 can include a first portion 1602 and a second portion 1604 extending from a base shape 1624. The base shape 1624 can space the first portion 1602 and the second portion 1604 from the shell 102. The base shape 1624 can be defined by a portion of the shell 102. In some embodiments, the base shape 1624 can be separate from or part of the first portion 1602 and / or the second portion 1604. The first portion 1602 , the second portion 1604 , and the base shape 1624 can together define an anchor 1608 for engaging the closure assembly 1500 .

[0183] The second portion 1604 can extend inwardly from the base shape 1624 along the inner surface of the shell 102. The second portion 1604 can have an inner surface 1616 and an outer surface 1618, as well as an edge 1620 between the inner surface 1616 and the outer surface 1618. The first portion 1602 can extend from the base shape 1624 in a direction away from the second portion 1604. The first portion 1602 can define an inner surface 1610 and an outer surface 1612, as well as an edge 1614 between the inner surface 1616 and the outer surface 1618. The inner surface 1610 of the first portion 1602 can extend into the inner surface 1616 of the second portion 1604. The first portion 1602 and the second portion 1604 can be of the same size. In one embodiment, as shown, first portion 1602 can extend further into base shape 1624 than second portion 1604 .

[0184] As shown in FIG. 14 , the rim connection structure 1600 is receivable in the frame connection structure 1516. For example, the rim connection structure 1600 may be received in the recess 1522. The zipper strip 1502 may snap fit or flex around the rim connection structure 1600 as indicated by arrow 1630. When the zipper strip 1502 engages the rim connection structure 1600, the rim connection structure 1600 may fit within the recess 1522. An edge 1614 of the first portion 1602 of the rim connection structure 1600 may abut the neck 1526 of the second frame connection structure 1520. The catch feature 1524 is engageable with the second portion 1604 of the rim connection structure 1600 with the catch feature 1524 extending around the edge 1620 of the second portion 1604. The base feature 1624 may fit within the gap 1530. When the rim connection structure 1600 is within the recess 1522, the base feature 1624 can position the zipper strip 1502 flush or nearly flush with the outer surface 138 of the shell 102. For example, the outer surface 1610 of the first portion 1602 can abut the inner surface 1532 of the zipper strip 1502. The second frame connection structure 1520 and the second portion 1604 can act to prevent movement across the rim connection structure 1600. The catch feature 1524 and the second portion 1604 can act to prevent movement across the rim connection structure 1600 towards the second shell 102.

[0185] The recess 1522 can define a volume larger than the volume of the rim connection structure 1600 to facilitate installation or insertion. In another embodiment, the recess 1522 can define a volume smaller than the volume of the rim connection structure 1600 and can stretch or flex to receive the rim connection structure 1600 to define an interference fit. The interference fit can reduce play between the closure assembly 1500 and the shells 102, 104.

[0186] As previously mentioned, the two shells 102, 104 are aligned and the closure assembly 1500 can engage at least a portion of the rim connection structures 1600 of both shells 102, 104 during installation. In other embodiments, the frame connection structure 1516 of the first zipper strip 1502 of the closure assembly 1500 can individually engage with the first rim connection structure 1600 of the first shell and the second zipper strip 1502 of the closure assembly 1500 can individually engage with the second rim connection structure 1600 of the second shell 104. After installation of each individual shell 102, 104, with the shells 102, 104 configured as a suitcase, the frame connection structures of the first zipper strip 1502 and the second zipper strip 1502 can be secured together to form the closure assembly 1500. Similarly, the zipper strips 1502 can be separately removed and replaced.

[0187] As shown, the closure assemblies 1500 of this embodiment can be slidably attached to the rim connection structure 1600 and / or can bend or snap-fit ​​attached to the rim connection structure 1600. For a snap-fit ​​attachment, a first portion of the rim connection structure 1600 can be inserted into the recess 1522 through the gap 1530. As shown in FIG. 15A, the frame connection structure 1516 can bend or flex outwardly as shown by arrow 1640 to temporarily expand the size of the opening to accommodate the first portion 1602. Once inserted, the outer surface 1610 of the first portion 1602 can contact the inner surface 1532 of the frame connection structure 1516. The edge 1614 of the first portion 1602 can contact the neck 1526 of the second frame connection structure 1520 when fully inserted into the recess 1522. After deflecting outwardly, the catch feature 1524 of the frame coupling structure 1516 can return to the first position and pass over the edge 1620 of the second portion 1604. The catch feature 1524 can then be positioned under the edge 1620 of the second portion 1604 to capture and hold the base feature 1624 within the recess 1522. The catch feature 1524 can additionally or alternatively engage the inner surface 1612 of the second portion 1604 as shown in FIG. 15B. To remove the closure assembly 1500, the catch feature 1624 can deflect from the inner surface 1616 of the second portion 1604 and pass over the edge 1620 to release the catch feature 1524 from the second portion 1604. The first portion 1602 can then be removed from the recess 1522 through the gap 1530. The snap-fit ​​attachment can begin at one end of the zipper strip 1502 and the snap-fit ​​to the rim connection structure 1600 progresses along the length of the zipper strip 1502 to a second, opposite edge.

[0188] Prior to installation, the closure assembly 1500 can be aligned to the rim connection structure 1600 as shown in FIG. 13. In some embodiments, the closure assembly 1500 can be installed to either shell 102, 104 in the same process or can be installed to the shells 102, 104 separately. The closure assembly 1500 can be installed to the rim connection structure 1600 by the first portion 1602 and the second portion 1604 entering the recess 1522 and engaging the closure assembly 1500 along the length of the rim connection structure 1600. For example, a snap fit engagement can start at one end and move to another end (e.g., occurring along the length of the rim connection structure 1600). To remove the closure assembly 1500, the closure assembly 1500 can be bent or opened, such as by moving in the opposite direction to that of installation, out of the open end of the rim connection structure 1600. The surfaces of the closure assembly 1500 and / or the rim connection structure 1600 can be smooth to facilitate installation and / or removal.

[0189] In one embodiment, each zipper strip 1502 is individually attachable to the rim connection structure 1600 on the respective shell 102, 104. In another embodiment, each zipper strip 1502 is individually removable from the respective shell 102, 104. In another embodiment, replacement zipper strips 1502 can be individually attached onto the rim connection structure 1600 on the respective shell 102, 104 to replace zipper strips 1502 that have been removed from the respective shell 102, 104. This allows a user to replace only a portion of the closure assembly 1500 or to combine different zipper strips 1502 having desired characteristics or to achieve a desired aesthetic (e.g., color or texture).
