- The present disclosure generally relates to bags, carrying cases and luggage systems.
- Description of the Related Art
- Bags or carrying cases are a handy way to transport items. Bags having shoulder straps are convenient because the user's hands may remain free while the bag is being carried. The carrying needs of the user may change, with the user requiring a bag with more or less carrying capacity. For example, in the case of a messenger bag or briefcase, the carrying needs of the user may change between individual parts of a trip. Sleek and low-profile bags are chic but have a limited carrying capacity. Bags with large carrying capacities may be bulky or appear less fashionable. Current bags with expandable capacity typically utilize zippers, buttons or the like to deploy hidden compartments. However, zippers and buttons detract from the aesthetics and sleek appearance of certain bags such as messenger bags. Thus, existing bags or carrying cases often require a user to compromise between fashion and utility.
- As mentioned above, bags and carrying cases such as a messenger bag may be worn over the shoulder and used to carry items from one place to another. The user may need to carry more or less items on different parts of the user's trip. A bag having a large carrying capacity may be needed only briefly. Messenger bags having a sleek, low-profile look are chic and elegant but may not accommodate all the carrying needs of the user. Zippers and other conventional methods of expanding the capacity of bags would detract the sleek aesthetic appeal of messenger bags and other carrying cases. What is needed is a bag or carrying case that can be compacted into a low-profile design when the user does not need a large carrying capacity, thereby giving the bag a sleek look.
- A bag having an expansion member configured to reversibly expand an outer panel away from a central frame of the bag is provided. The expansion member can assume a collapsed configuration whereby the outer panel is pulled flush with the central frame and gives the bag a sleek look. The expansion member can assume an expanded configuration whereby the outer panel extends away from the central frame, thereby increasing the carrying capacity of the bag.
- Certain embodiments described herein are directed to bags, carrying cases, and luggage systems for adjusting carrying capacity to a user's needs. However, it will be appreciated that apparatuses and systems described herein encompass a wide variety of bags, carrying cases, luggage systems including but not limited to suitcases, carry-ons, totes, messenger bags, laptop bags, backpacks, handbags, briefcases, carrying cases for electronic devices, and bags in general. Moreover, the systems and apparatuses may have application to other fields. In some embodiments, the systems may be used for the storage of tools, electronics, medical supplies, photography equipment and other items.
- A bag has a frame with a lip disposed about a periphery of the frame. The frame has an outer panel and an extension that couples the outer panel to the frame. The extension is configured to have an expanded configuration and a collapsed configuration. The extension extends laterally outward beyond the lip of the frame when the extension is in the expanded configuration, and the extension resides laterally inward of the lip of the frame when the extension is in the collapsed configuration. A first magnet is disposed at an end surface of the outer panel. A second magnet is disposed at an inner surface of the frame. The first magnet is configured to magnetically couple to the second magnet when the extension member is in the collapsed configuration. The extension further comprises a hinge. The hinge is configured to pull the outer panel flush with the lip of the frame when the extension is in the collapsed configuration.

FIG. 1 A depicts a non-limiting exemplary embodiment of anexpandable bag 100 having anexpandable portion 102 that can reversibly extend from aframe 104 of thebag 100. As discussed in more detail below, theexpandable portion 102 can be formed by anextension 106 that may connect anouter panel 110 of thebag 100 to theframe 104. Thebag 100 may include more than oneexpandable portions 102. For example, thebag 100 can include anexpandable portion 102 on anouter panel 110 of thebag 100 and a second expandable portion (not shown) on aninner panel 112 of thebag 100. Additionally and alternatively, thebag 100 may include a plurality nestedexpandable portions 102. For example, thebag 100 may include a firstexpandable portion 102 on anouter panel 110 of thebag 100 and a second expandable portion (not shown) that extends from theouter panel 110 of thebag 100. Theouter panel 110 of thebag 100 can be a rigid or resiliently flexible rectangular member such as a plank formed on theextension 106, such as by inserting a plank formed as a rectangular high density polyethylene sheet into a plank pocket to form theouter panel 110. - The
bag 100 may include a plurality ofextensions 106. The plurality ofextensions 106 can be configured to be independently deployed from one another. For example, the embodiment depicted inFIG. 1A shows abag 100 having anextension 106 deployed along abottom edge 114 of thebag 100. Additionally and alternatively, thebag 100 can include anextension 106 that can be deployed along atop edge 116 of thebag 100. Thebag 100 can include anextension 106 along atop edge 116 of thebag 100 and an extension along thebottom edge 114 of the bag, with eitherextension 106 being adapted to be deployed independent of theother extension 106. - The
bag 100 may include astrap 120. Additionally and alternatively, thebag 100 may have nostrap 120 or thebag 100 may have more than one straps 120. Thestrap 120 can be connected to theframe 104 of the bag. Additionally and alternatively, thestrap 120 may be connected to thebag 100 at a location other than the frame 104 (e.g., the outer panel 110). -
FIG. 1B shows the embodiment of thebag 100 depicted inFIG. 1A in the collapsed configuration of thebag 100. As shown, in the collapsed configuration, theouter panel 110 may lie close to alip 122 of theframe 104. Theouter panel 110 may extend laterally beyond thelip 122 when thebag 100 is in the collapsed configuration. Alternatively, thelip 122 may extend laterally beyond theouter panel 110 when the bag is in the collapsed configuration. In some embodiments, theouter panel 110 is substantially flush with thelip 122 when thebag 100 is in the collapsed configuration. In some embodiments, when the bag is in the collapsed configuration, theouter panel 110 is aligned with thebottom edge 114 in a manner such that theouter panel 110 forms a seemingly continuous surface with thebottom edge 114. -
FIG. 1C shows a side view of the embodiment of thebag 100 depicted inFIG. 1A . Thebag 100 can include aclosure 160 configured to control access to the interior of thebag 100. Theclosure 160 can be aflap 162 that folds over amouth 164 of thebag 100. The closure depicted inFIG. 1C is illustrative and not to be taken as limiting. Access to the bag can be through other means such as hidden zippers, Velcro, snaps, buckles, and other means known in the art. - Additionally and alternatively, the
bag 100 may include fasteners (not shown) that allow themouth 164 of thebag 100 to be opened or closed. Thebag 100 may include adivider 162. Thedivider 162 can attach to theframe 104 or to another feature of thebag 100. Thedivider 162 may divide the interior of thebag 100 into different compartments. Thedivider 162 may separate anexpansion compartment 166 from aframe compartment 168. The bag may includemultiple dividers 162. Thedivider 162 may be made from an elastic fabric such as spandex. Thedivider 162 may be made from a material including cotton, nylon, polyester, or other material. -
FIG. 2 depicts a non-limiting exemplary embodiment of thebag 100 viewed in cross-section. The embodiment shown inFIG. 2 shows in greater detail the mechanism in which the bag can be expanded and retracted. As shown inFIG. 2 , the mechanism utilizesmagnets 124 a, b to retain at least a portion of theouter panel 110 within thelip 122 of theframe 104 when thebag 100 is in the collapsed configuration. However, as discussed below, theouter panel 110 may be retained within thelip 122 by other methods in addition to, or instead of, using themagnets 124 a, b. - As shown in
FIG. 2 , theouter panel 110 can be coupled to theframe 104 by anextension 106. Theextension 106 can be made of a material such as nylon, cotton, polyester, silicone, spandex, or other suitable material. Theframe 104 can be made of foam, plastic, metal, or other suitable material. Theframe 104 can include arecess 126 a configured to receive and retain amagnet 124 a. Theouter panel 110 can include arecess 126 b configured to receive and retain amagnet 124 b. Therecesses 126 a, b can be configured so that themagnets 124 a, b align with one another when alateral surface 130 of theouter panel 110 is flush with thelip 122 of theframe 104. Therecesses 126 a, b can be configured so that thelateral surface 130 is proud or recessed relative to thelip 122 of theframe 104 when thebag 100 is in the collapsed configuration. Theextension 106 can have adistal end 132 that couples to aninner surface 134 of theouter panel 110. Theextension 106 can have aproximal end 136 that couples to aninternal surface 140 of theframe 104. - Still referring to
FIG. 2 , themagnets 124 a, b can be configured to magnetically interact with one another when thebag 100 is in the collapsed configuration, thereby retaining theouter panel 110 within theframe 104 and giving the bag 100 a sleek look. AsFIG. 2 shows, themagnets 124 a, b can be separated by agap 142 that is formed between anend surface 144 of theouter panel 110 and theinternal surface 140 of theframe 104. However, in some embodiments themagnets 124 a, b will be configured so that nogap 142 is formed between theend surface 144 and theinternal surface 140 of theframe 142. -
FIG. 3A depicts a cross-sectional view of an embodiment ofbag 100 when thebag 100 is in the expanded configuration.FIG. 3B shows the embodiment depicted inFIG. 3A when thebag 100 is in the collapsed configuration. As shown inFIGS. 3A and 3B , theproximal end 136 of theextension 106 can couple to a portion of theframe 104 that is laterally outward from themagnet 124 a. Additionally and alternatively, thedistal end 132 of the extension may couple to a portion of theouter panel 110 that is laterally outward of themagnet 124 b (as shown inFIG. 4 ). Accordingly, in some embodiments theextension 106 may extend through at least a portion of thegap 142 and be pinched between themagnets 124 a, b when thebag 100 is in the collapsed configuration. In other words, theextension 106 may either not pass, pass once, or pass more than once between themagnets 124 a, b when thebag 100 is in the collapsed configuration. - The present disclosure encompasses many different placements of the magnets. For example, additionally and alternatively, one or
more magnets 124 c, d may be located on theextension 106.FIG. 4 shows that thebag 100 can havemagnets 124 c, d on theextension 106. Themagnets 124 c, d on theextension 106 can be configured to magnetically couple to themagnets 124 a, b that are attached to theframe 104 and theouter panel 110. Thegap 142 has been exaggerated inFIG. 4 for illustrative purposes. However, any, all, or none of the magnets 124 a-d can be recessed in order to eliminate or minimize thegap 142. -
FIG. 5 shows theextension 106 of thebag 100 can includemagnets 124 c, d that are configured to magnetically couple with one another. Themagnets 124 c, d may be located on opposite faces of theextension 106. Theextension 106 may run between themagnets 124 c, d. -
FIG. 6 depicts an alternative embodiment of thebag 100 havingmagnets 124 c, d on theextension 106 that can be configured to magnetically couple tomagnets 124 a, b on the frame and theouter panel 110. -
FIGS. 7A and 7B illustrate an embodiment of thebag 100 having anextension 106 that includes ahinge 146. Thehinge 146 can be configured to snap open when thebag 100 is in the expanded configuration (seeFIG. 7A ) and to snap shut when thebag 100 is in the collapsed configuration (seeFIG. 7B ). Thehinge 146 can be interposed between aproximal portion 150 and adistal portion 152 of theextension 106. Thehinge 146 can be a living hinge formed of an elastically deformable material (e.g., silicone). Thehinge 146 can be formed as a thin section of material interposed between the proximal and distal portions of theextension 106, thereby biasing thehinge 146 to buckle between an open and shut configuration. Thebag 100 can have anextension 106 that includes a plurality ofhinges 146. For example, thebag 100 may have aproximal hinge 154 positioned close to theframe 104 and configured to help pull theouter panel 110 flush to theframe 104. - The present disclosure includes combinations of the aspects herein disclosed. For example,
FIGS. 8A and 8B show that an embodiment of thebag 100 may include both ahinge 146 andmagnets 124 a, b.FIG. 8A depicts a cross-sectional view of thebag 100 in the expanded configuration.FIG. 8B shows the embodiment ofFIG. 8A when thebag 100 is in the collapsed configuration. - The present disclosure can be applied to
bags 100 having other configurations other than an over the shoulder tote or cross-body messenger bag. For example, the present disclosure can include duffle bags, backpacks, suitcases, totes, satchels, and other configurations of bags.FIG. 9A illustrates a non-limiting exemplary embodiment of abag 100 configured to be worn as a backpack. Thebag 100 can include a pair ofshoulder straps 176 attached to amedial panel 178 of the bag. Theextension 106 can be configured to extend aback panel 180 laterally away from theframe 104.FIG. 9B shows the embodiment of thebag 100 depicted inFIG. 9A when thebag 100 is in the collapsed configuration. -
FIG. 10 provides schematic partial illustrations of expanded 202 and retracted 204 configurations of abag 200 according to another embodiment. Thelower frame 204 of thebag 200 comprises twoseparable sections first magnet 210 is attached to an upper surface of one of thesections 206, and asecond magnet 212 is attached to a lower surface of the other one of thesections 208. Thefirst section 206 of the lower frame may be connected to theback panel 288 and thesecond section 208 may be connected to thefront panel 284. Thebag 200 may be stitched at aslight angle 220 and act as a guide to help retract. In the retractedconfiguration 204, thesecond section 208 of the lower frame is slid over thefirst section 206 and secured in place by the twomagnets -
FIG. 11B depicts the embodiment of thebag 100 shown inFIG. 11A in the collapsed configuration. In the collapsed configuration,inner frame 302 can nest inside theouter frame 304, andpanel 308 can fold into an interior space of thebag 100. Theinner frame 302 may nest inside theouter frame 304 in a manner such that theexterior surface 320 of thebag 100 is flush with the edges of theouter frame 304 which creates a sleek and streamlined appearance when the bag is in the collapsed configuration. In some embodiments, one or more coupling devices or guides are positioned in the interior of the bag to facilitate alignment of theexterior surface 320 of thebag 100 with the edges of theouter frame 304. In some embodiments, thebag 100 has more than one expandable portions. - Conditional language, such as “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include, while other embodiments do not include, certain features, elements, and/or steps.
