Definitions

  • the present disclosure generally relates to luggage. More particularly, the present disclosure relates to zipper configurations for expandable luggage.
  • Luggage items such as suitcases, backpacks, duffel bags, briefcases, computer bags and so on, often include a primary opening/closing zipper to allow a user to access an inner compartment of the luggage item.
  • the luggage item may also include an expansion zipper and a gusset for increasing the storage space of the luggage item.
  • Each of the zipper halves of the expansion zipper is attached to an opposing side of the gusset.
  • the expansion zipper is zipped, the gusset is kept underneath the expansion zipper on the interior thereof.
  • the expansion zipper is unzipped, the gusset connected between the zipper halves of the expansion zipper expands and forms a portion of the luggage item, thereby increasing a storage space of the luggage item.
  • An expansion zipper of a luggage item is usually arranged along side and/or top panels or portions thereof of the luggage item, and is often configured to be positioned side-by-side with the primary opening/closing zipper along the side and/or top panels of the luggage item.
  • Such configuration can be confusing to a user, especially when the expansion zipper is zipped. A user may mistake the primary opening/closing zipper for the expansion zipper, or vice versa.
  • the expansion zipper takes extra space along a depth dimension of the luggage item. Accordingly, panels or shells used for making non-expandable luggage cases that meet the size restrictions specified by airline companies may not be used for making expandable luggage cases due to the extra depth added by the expansion zipper. Any dimensional adjustment involved may result in additional cost in luggage design and manufacture.
  • Documents that may be related to the present disclosure in that they include various approaches to luggage zipper configurations include EP 1638427 , EP 1689263 , FR 2951915 ( WO 2010122247 ), GB 2173393 , TWM339233 , US 2002148743 , US 2007267262 , US 6609598 , US 7255145 and WO 2011093984 . These proposals, however, may be improved.

  • the first zipper mechanism and the second zipper mechanism may be arranged in a superimposed or overlapping or overlying or coextensive configuration.
  • the first and second zipper mechanisms may be configured to zip and unzip independent of each other.
  • the second zipper mechanism may include a gusset.
  • the gusset may connect the second zipper mechanism and one of the peripheral edges of the opposing portions to thereby operably engage the peripheral edge of the opposing portion.
  • the opposing portions of the luggage item may be maintained in a closed unexpanded configuration when the first zipper mechanisms is zipped, and may be maintained in a closed and expanded configuration when the second zipper mechanisms is zipped.
  • the first zipper mechanism may include opposing longitudinal edges
  • the second zipper mechanism may include opposing longitudinal edges.
  • One of the opposing longitudinal edges of the first zipper mechanism and one of the opposing longitudinal edges of the second zipper mechanism may operably engage one of the peripheral edges of the opposing portions.
  • the other of the opposing longitudinal edges of the first zipper mechanism and the other of the opposing longitudinal edges of the second zipper mechanism may operably engage the other of the peripheral edges of the opposing portions.
  • the gusset and one of the first or second zipper mechanisms may be arranged in an aligned configuration.
  • the gusset may define at least in part a wedge shape.
  • one of the first or second zipper mechanisms may be configured to be exterior to the other of the first or second zipper mechanisms.

  • the zipper teeth 210 of the fourth zipper half 180 hangs down into the interior recess of the luggage case 100, at a distance from the zipper teeth 208 of the third zipper half 178, when not secured to the matching third zipper half 178.
  • the zipper teeth 210 on the fourth zipper half 180 are not in vertical alignment with the zipper teeth 206 of the second zipper half 172, nor are the engaged zipper teeth 204, 206, 208, 210 of respective zipper mechanism 164, 166 vertically aligned. Contrast the vertical alignment of the zipper mechanisms 164, 166 of the first and second zipper tapes in Fig. 4B .
  • the zipper teeth 204, 206, 208, 210 in the first and second zipper tapes are engaged and vertically aligned, as well as in longitudinal alignment, and the gusset 156 is gathered and extending inwardly and away from the zipper tapes.
  • the zipper teeth 204, 206, 208, 210 of the zipper mechanisms 164, 166 may not be vertically aligned or may not be longitudinally aligned, and as such may be laterally offset from one another, if the widths of the zipper tape halves are so designed. Such offset in widths may be introduced by using zipper tapes of different dimensions, or incorporating gussets of selected and various sizes to either or both longitudinal edges of the second zipper mechanism 166, or the first zipper mechanism 164, for additional expandability, among other options.
  • the first zipper mechanism 164 is unzipped and the second zipper mechanism 166 is zipped.
  • the first and second longitudinal halves 170, 172 of the zipper tape of the first zipper mechanism 164 are relatively narrow in width. This narrow width reduces the likelihood that the unused zipper tapes of the first zipper mechanism 164 will be snagged and/or damaged as the expanded case is handled.
  • the zipper tape of the first zipper mechanism 164 may be made of relatively stiff material (such as PU coated or plastic-impregnated fabric) to keep the zipper halves 170, 172 of the first zipper mechanism 164 from dangling or bending. Accordingly, when the first zipper mechanism 164 is unzipped, the zipper halves 170, 172 thereof may remain relatively flat or flush with the extensions of the peripheral edges 138, 140 of the front and rear shells 102, 104 of the luggage case 100, thereby reducing damage that may be caused during usage.
  • relatively stiff material such as PU coated or plastic-impregnated fabric
  • the opening/closing zipper and the expansion zipper are usually in a side-by-side configuration whether in the expanded or unexpanded state.
  • the dual closure mechanism described herein is configured with the two zipper mechanisms 164, 166 displaced one below or under the other in a coextensive and/or overlying or overlapping manner (see Fig. 4B ). It is contemplated that the terms coextensive, overlying or overlapping, in the context here, may generally refer to a same or similar relative orientation and positioning between the two zipper tapes, such as that shown in Fig. 4B .
  • each of these terms may also have different meanings, such as where “overlying” also encompasses the respective zipper teeth not necessarily being longitudinally aligned between the two zipper mechanisms when zipped (Such as Fig. 10 ). Or, for instance, “overlapping” may also encompass a relative positioning where the respective zipper teeth are only partially longitudinally aligned. Other distinctions between these words may become apparent through the additional description and figures herein.
  • this configuration is unlikely to cause such confusion because when the luggage case 100 is in the unexpanded state only the first zipper mechanism 164 for opening and closing the luggage case 100 is exposed to a user. Likewise, when the luggage case 100 is in the closed and expanded configuration, only the second zipper mechanism 166 used to open the case is exposed to the user.
  • the side-by-side orientation of the conventional expansion zipper may also allow the front and rear shells to more easily shift relative to one another during use (whether expanded or not), which is unsightly and may affect the towing of the luggage case.
  • the side-by-side configuration also takes up space between the front and rear shells in the unexpanded configuration.
  • the front and rear shells used in making conventional expandable luggage cases may be designed and manufactured with different dimensions from those for non-expandable luggage cases, which may result in additional design and manufacturing costs.
  • the superimposed or overlaying or overlapping or coextensive configuration of the dual closure mechanism as described herein does not necessarily take extra space along a depth dimension of the luggage case 100, and maintain a single-zipper width between shells 102, 104 when in the unexpanded configuration. Accordingly, the superimposed or overlaying or overlapping or coextensive configuration for expandability as described herein provides enhanced compatibility with existing luggage designs.
  • the superimposed or overlaying or overlapping or coextensive configuration of the first and second zipper mechanisms 164, 166 may allow easy operation for a user as compared to a conventional side-by-side zipper configuration.
  • the user may have to perform two zipper operations when packing a luggage case: i) an unzipping operation of the expansion zipper (second zipper mechanism 166 in the description above) to increase the overall volume of the luggage case; and ii) a zipping operation of the opening/closing zipper (first zipper mechanism 164 in the description above) of the luggage case to close the luggage case for transportation.
  • the user when packing a luggage case 100 having the dual closure configuration as described herein, the user simply selects the corresponding zipper mechanism 164, 166 for unexpanded or expanded configuration.
  • the other zipper mechanism 164, 166 need not be actuated (See Fig. 4A for unexpanded, and Fig. 6 for expanded).
  • the second zipper mechanism 166 may serve as a dual-function zipper that may allow the user to achieve two goals, i.e., closing the luggage case 100 and expanding the overall volume of the luggage case 100, through one single zipping operation of the second zipper mechanism 166.
  • Another advantage of the dual closure zipper configuration as described herein is that it may provide additional security.
  • the additional security is provided when both the first and second zipper closure mechanisms 164, 166 are zipped, which provides a dual-layer of zippers to penetrate before accessing the interior compartment (see Fig. 4B ). Additionally, if the first and second zipper mechanisms 164, 166 are not aligned with one another, such as with respect to Fig. 10 , security aspect may be further enhanced. More advantages of the superimposed or overlaying or overlapping or coextensive zipper configuration as described herein may be appreciated by one skilled in the art.
  • one example of the hinge element 142 of the luggage case 100 is flexible material, and has a rectilinear shape with opposing longitudinal edges 212 defining a length dimension and opposing short edges 214 defining a width dimension.
  • Other aspect ratios of the hinge element 142 may be contemplated.
  • the hinge element 142 of the luggage case 100 may include an outer layer 216 and an inner layer 218.
  • the outer layer 216 may be formed of relatively durable material to withstand acting as a flexible hinge, such as plastic, metal, natural or man-made woven or non-woven fabrics, natural materials, such as leather and so on.
  • the inner layer 218 may be formed of material similar to that used for forming inner liners 106, 108 of a luggage case 100, such as polyester or other natural or synthetic fabric.
  • the inner and outer layers 216, 218 may be joined together by any suitable method including, but not limited to, sewing, bonding, adhering, stapling and so on.
  • the hinge element 142 of the luggage case 100 may include only one layer.
  • the two opposing longitudinal edges 212 of the hinge element 142 may be joined to portions of the peripheral edges 138, 140 about which the front and rear shells 102, 104 are desired to pivot open and close. With respect to Figs. 1 , 2 and 3 , this portion is on the left panel 130 132 of each of the front and rear shells 102, 104. In some examples as shown in Figs. 5 and 7 , the longitudinal edges 212 of the hinge element 142 may be secured to the peripheral edges 138, 140 by the S-shaped sheaths 188, 190 as described above for the zipper mechanisms 164, 166, or any other suitable connection method.
  • the longitudinal edges 212 of the hinge element 142 may be received within the exterior recesses of the first and second S-shaped sheaths 188, 190, with the peripheral edges 138, 140 of the respective luggage shells 102, 104 being positioned in the inner recesses as noted above.
  • the layers positioned in each recess then may be attached to the sheaths 188, 190 and the peripheral edges 138, 140 of the front and rear shells 102, 104 by any of a number of attachment mechanisms, such as sewing, bonding, stapling and so on.
  • the outer section 192, 198 of the sheath 188, 190 is not sewn through in some instances to allow for the protection of the attachment mechanism, as described above.
  • the longitudinal edges 212 of the hinge element 142 may be received within the respective interior recesses of the first and second sheaths 188, 190, along with the peripheral edges 138, 140 and liners 106, 108.
  • the hinge element 142 would naturally bend inwardly or protrude toward the inner compartment of the luggage case 100 when the luggage case 100 is unexpanded. Such natural inward bending advantageously protects the hinge element 142 from being pulled or snagged during use.
  • the gusset 156 may terminate at the hinge element 142, and be joined to the transverse edges 214 of the hinge element 142 by sewing, bonding, adhering, stapling, or any suitable attaching method.
  • the gusset 156 may terminate under the hinge element 142, terminate over the hinge element 142, or the short opposing ends 214 of the hinge element 142 may be sandwiched between the inner layer 218 and the outer layer 216 of the hinge element 142.
  • the second zipper mechanism 166 may also be joined to the transverse edges 214 of the hinge element 142 in a similar fashion.
  • the zipper tape of the second zipper mechanism 166 may terminate above or under the hinge element 142.
  • the end portions of the second zipper of the second zipper mechanism 166 may be sandwiched between the inner and outer layers 216, 218 of the hinge element 142 and attached thereto by sewing, bonding, adhering, stapling, or any suitable attaching method.
  • a retainer may be provided at each end of the zipper tape of the second zipper mechanism 166 to prevent the associated zipper slider from coming off the zipper track 168.
  • end portions 220 of the longitudinal edges of the zipper tape of the first zipper mechanism 164 may be unattached to the luggage shells 102, 104 or the transverse edges 214 of the hinge element 142, as best shown in Figs. 1 and 2 .
  • Such configuration would allow the zipper halves 170, 172 at the end portions of the first zipper mechanism 164 to move and adjust to accommodate the additional width added by the gusset 156 when the luggage case 100 is used in its expanded state.
  • the end portions 220 of the first zipper mechanism 164 may be tucked into the space between the first zipper mechanism 164 and the second zipper mechanism 166.
  • the end portions 220 of the zipper tape of the first zipper mechanism 164 may be provided with Velcro® tape, snap fastener or other suitable fastener to releasably attach the end portions 220 of the zipper tape of the first zipper mechanism 164 to an outer surface of the hinge element 142 or any suitable portion of the luggage case 100.
  • the gusset 156 may be of consistent width along its length.
  • the width of the hinge element 142 may be similar to the width of the gusset 156, or the combined width of the second zipper mechanism 166 and the gusset 156.
