Luggage systems

Description

BACKGROUND

Rolling suitcases that are small enough to carry on many airplanes are commonplace. Some rolling suitcases also have attached shoulder straps so that they can be carried as a backpack. However, these designs have certain limitations.

SUMMARY

Embodiments of the present inventive concepts provide a luggage system that addresses the limitations of the conventional configurations.

In some embodiments, the luggage system can include a removable or detachable portion that can be mounted to a front of a rolling suitcase bag.

In some embodiments, the luggage system can include a removable or detachable portion that can be mounted to a rear of a rolling suitcase bag, opposite the front.

In some embodiments, the removable or detachable portion positioned at the front and/or back can be mounted to a suitcase unit that is not rolling.

In some embodiments, the system can include a checkpoint-friendly configuration per TSA regulations.

In some embodiments, a detachable backpack, briefcase, tote, or similar bag can be included in the system as the removable portion.

In some embodiments, the removable portion can be relatively smaller, and used separately from, and independently of, the larger, suitcase bag, when detached. For example, the removable portion can be taken to meetings or used to carry items when touring a destination location, without having to bring the entire suitcase along.

In some embodiments, a system incorporating the features of the present inventive concepts enables a traveler to travel with only one bag. The system is easier to manage by a traveler—leaving one hand free to attend to other items, or both hands free if the entire system is worn as a backpack

In some embodiments, a system incorporating the features of the present inventive concepts allows for passage through TSA security checkpoints in a more traveler-friendly procedure, that can be relatively quicker and easier.

In some embodiments, a system incorporating the features of the present inventive concepts allows for a single bag to be carried and stowed in an airplane, whether under the seat or in an overhead rack, in a manner that is relatively easier and simpler. In some embodiments, the system is configured to qualify as a carry-on bag, in view of United States' requirements for carry-on bags. In some embodiments, the system is configured to qualify as a carry-on bag, in view of international requirements for carry-on bags.

In some embodiments, a system incorporating the features of the present inventive concepts allows for the improvement of the one-bag travel experience for travelers, so that they can travel efficiently with a single, fairly small, carry-on piece of luggage.

As noted above, it would be helpful if the single piece of luggage could be separated at certain points along the journey, so that excursions to meetings or tourist sites could be accomplished in more traveler-friendly fashion, or so that items could be more readily accessed in flight.

In some embodiments, a luggage system is comprised of at least three detachable parts: 1. A “rear unit” or “suspension unit” which may include backpack straps and a compartment which can carry a computer, or a suit, or other fairly flat objects such as files, or may contain a handle or a shoulder strap or both so that when separated it can be carried as a briefcase or tote, 2. A “middle unit” or “suitcase unit” which can carry clothes, toiletries, and/or a variety of other objects, 3. A “front unit”, which, among other embodiments, can have quick-access pockets for storing items in an organized manner. The “rear unit” and the “front unit” can be independently attached or unattached to the “middle unit”. Once unattached from the “middle unit”, the “front unit” and the “back unit” can then be attached together, to form, among other embodiments, a smaller backpack or “daypack”, or alternatively, among other embodiments, a briefcase or tote. Alternatively, both the “front unit” and the “back unit” may be used independently (for example, the “back unit” can be used as a slim backpack that is constructed and arranged to carry a computer or other items. In some embodiments, the “front unit” can be constructed and arranged to independently be hung on an airplane seat to provide easy access to items (such as a tablet, book, headphones, etc., for example) during flight.

In some embodiments, a hip-belt can be included on the “suspension unit”. In some embodiments, the hip belt can be hidden or folded behind a padded panel designed to make the back of the wearer feel more comfortable when the backpack is worn. This hip-belt can then be pulled out from behind the panel by means of a loop attached to the hip-belt, making it easy to grab while wearing the pack, as opposed to currently available packs requiring a user to remove the pack in order to pull out the hip belt. This “pull out while wearing” feature is further enhanced by a crease in the hip belt on each side of the pack, so that, when the belt is stored, it folds to the correct location for the loop to be easily grabbed and pulled.

In some embodiments, a modular backpack comprises a first body, a second body and a third body. The first body comprises a backpack suspension, a first storage region and a first portion of a first attachment mechanism.

DETAILED DESCRIPTION

Reference will now be made in detail to the present embodiments of the technology, examples of which are illustrated in the accompanying drawings. Similar reference numbers may be used to refer to similar components. However, the description is not intended to limit the present disclosure to particular embodiments, and it should be construed as including various modifications, equivalents, and/or alternatives of the embodiments described herein.

It will be understood that the words “comprising” (and any form of comprising, such as “comprise” and “comprises”), “having” (and any form of having, such as “have” and “has”), “including” (and any form of including, such as “includes” and “include”) or “containing” (and any form of containing, such as “contains” and “contain”) when used herein, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

It will be further understood that, although the terms first, second, third etc. may be used herein to describe various limitations, elements, components, regions, layers and/or sections, these limitations, elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one limitation, element, component, region, layer or section from another limitation, element, component, region, layer or section. Thus, a first limitation, element, component, region, layer or section discussed below could be termed a second limitation, element, component, region, layer or section without departing from the teachings of the present application.

It will be further understood that when an element is referred to as being “on”, “attached”, “connected” or “coupled” to another element, it can be directly on or above, or connected or coupled to, the other element, or one or more intervening elements can be present. In contrast, when an element is referred to as being “directly on”, “directly attached”, “directly connected” or “directly coupled” to another element, there are no intervening elements present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g. “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.).

It will be further understood that when a first element is referred to as being “in”, “on” and/or “within” a second element, the first element can be positioned: within an internal space of the second element, within a portion of the second element (e.g. within a wall of the second element); positioned on an external and/or internal surface of the second element; and combinations of one or more of these.

As used herein, the term “proximate” shall include locations relatively close to, on, in and/or within a referenced component, anatomical location, or other location.

Spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like may be used to describe an element and/or feature's relationship to another element(s) and/or feature(s) as, for example, illustrated in the figures. It will be further understood that the spatially relative terms are intended to encompass different orientations of the device in use and/or operation in addition to the orientation depicted in the figures. For example, if the device in a figure is turned over, elements described as “below” and/or “beneath” other elements or features would then be oriented “above” the other elements or features. The device can be otherwise oriented (e.g. rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terms “reduce”, “reducing”, “reduction” and the like, where used herein, are to include a reduction in a quantity, including a reduction to zero. Reducing the likelihood of an occurrence shall include prevention of the occurrence.

The term “and/or” where used herein is to be taken as specific disclosure of each of the two specified features or components with or without the other. For example, “A and/or B” is to be taken as specific disclosure of each of (i) A, (ii) B and (iii) A and B, just as if each is set out individually herein.

In this specification, unless explicitly stated otherwise, “and” can mean “or,” and “or” can mean “and.” For example, if a feature is described as having A, B, or C, the feature can have A, B, and C, or any combination of A, B, and C. Similarly, if a feature is described as having A, B, and C, the feature can have only one or two of A, B, or C.

The expression “configured (or set) to” used in the present disclosure may be used interchangeably with, for example, the expressions “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to” and “capable of” according to a situation. The expression “configured (or set) to” does not mean only “specifically designed to” in hardware. Alternatively, in some situations, the expression “a device configured to” may mean that the device “can” operate together with another device or component.

It is appreciated that certain features of the disclosure, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the disclosure which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable sub-combination. For example, it will be appreciated that all features set out in any of the claims (whether independent or dependent) can be combined in any given way.

It is to be understood that at least some of the figures and descriptions of the disclosure have been simplified to focus on elements that are relevant for a clear understanding of the disclosure, while eliminating, for purposes of clarity, other elements that those of ordinary skill in the art will appreciate may also comprise a portion of the disclosure. However, because such elements are well known in the art, and because they do not necessarily facilitate a better understanding of the disclosure, a description of such elements is not provided herein.

Terms defined in the present disclosure are only used for describing specific embodiments of the present disclosure and are not intended to limit the scope of the present disclosure. Terms provided in singular forms are intended to include plural forms as well, unless the context clearly indicates otherwise. All of the terms used herein, including technical or scientific terms, have the same meanings as those generally understood by an ordinary person skilled in the related art, unless otherwise defined herein. Terms defined in a generally used dictionary should be interpreted as having meanings that are the same as or similar to the contextual meanings of the relevant technology and should not be interpreted as having ideal or exaggerated meanings, unless expressly so defined herein. In some cases, terms defined in the present disclosure should not be interpreted to exclude the embodiments of the present disclosure.

In the embodiment shown in FIG. 1, the first portion of the first attachment mechanism 410 of the first body 100 is coupled to the second portion of the first attachment mechanism 420 of the third body 300. In the embodiment shown in FIG. 1, the first portion of the second attachment mechanism 460 of the second body 200 is coupled to the second portion of the second attachment mechanism 470 of the third body 300.

In the embodiment shown in FIG. 1, the first body 100 and the second body 200 are attached to the third body 300 by attachment mechanisms 400, 450, for example in the form of attachment zippers. In some embodiments, the attachment zippers are designed to be the same size and attached in the same shape to both the first body 100 and the second body 200. In other embodiments, first 100 and second 200 bodies could also be attached to each other by other types of attachment mechanisms, such as Velcro, clips, straps, hooks, bands with elastic properties, or other types of fasteners or attachment mechanisms.

By configuring the first and second attachment mechanisms 400, 450 to be the same size, shape or length, a modular system can be provided. In the embodiment shown in the side view of FIG. 1, and, further referring to the perspective views of FIGS. 1A1 and 1A2, a front portion of a backpack in the form of body 200, can be separated from the system 1000, in this case, separated from the third body 300 of the system 1000, by separating the second attachment mechanism 450. Similarly, a rear portion of a backpack, in the form of body 100, can likewise be separated from the system, in this case, separated from the third body 300 of the system 1000 by separating the second attachment mechanism 400.

Once separated, the first body 100 can be coupled directly to the second body 200. In particular, the first portion 410 of the first attachment mechanism 400 is configured to couple to the first portion 460 of the second attachment mechanism 450. In a case where the first and second attachment mechanisms 400, 450 comprise zippers, the first portion 410 of the first attachment mechanism 400 may include a zipper slider and zipper retainer box, while the second portion 420 of the first attachment mechanism 400 may include a zipper pin that mates with the zipper slider and zipper retainer box of the first portion 410 of the first attachment mechanism 400. Similarly, the first portion 460 of the second attachment mechanism 450 may include a zipper pin, while the second portion 470 of the second attachment mechanism 450 may include a mating zipper slider and zipper retainer box that corresponds to the first portion 460 of the second attachment mechanism 450. As shown in FIG. 1A2, as a result, the first body 100 can be coupled directly to the second body 200. In this example, the coupled first body 100 and second body 200 provide a daypack configuration, with the first body 100 providing the utility of a full suspension 110 along with a first pack volume at the first storage region 120, and with the second body 200 providing a second pack volume at the second storage region 220.

To accommodate this arrangement, the geometries of the first and second portions 410, 420 of the first attachment mechanism 400 and the geometries of the first and second portions 460, 470 of the second attachment mechanism 450 are arranged to match. In the case of the first and second attachment mechanisms being in the form of zippers, the matching zippers can be configured to have corresponding positional geometries, corresponding lengths, mating zipper teeth, and the like.

In some embodiments, the zipper tape of each of the first and second portions 410, 420, 460, 470 is coupled to portions of respective bodies 100, 200, 300 so that the zipper teeth extend in a direction away from the body 100, 200, 300 to which it is coupled, for mating with zipper teeth of a corresponding portion of a corresponding body 100, 200, 300. In some embodiments the zipper tape is coupled to the body 100, 200, 300 so that the zipper teeth extend in a direction that is substantially perpendicular to the body 100, 200, 300.

FIGS. 1B1 and 1B2 are perspective views of examples of matching zipper geometries for the first and second portions 410, 420 of the first attachment mechanism 400 and the first and second portions 460, 470 of the second attachment mechanism 450 in accordance with an embodiment of the present inventive concepts. In this example embodiment, the zippers of each of the first and second attachment mechanisms 400, 450 comprise a single zipper. The first and second portions 410, 420 of the first attachment mechanism 400 and the first and second portions 460, 470 of the second attachment mechanism 450 are coupled to the respective bodies in a generally arched-shaped, or upside-down-U-shaped, configuration. The right-side legs of each zipper portion 410, 420, 460, 470 have the same height Hz1 and the left-side legs of each portion 410, 420, 460, 470 have the same height Hz2. In some embodiments, the heights of the right-side legs Hz1 and the heights of the left-side legs Hz2 are in turn equal to each other, i.e., Hz1=Hz2. In addition, the horizontal portions of each zipper portion 410, 420, 460, 470 have the same width Wz.

By configuring the portions 410, 420, 460, 470 of the attachment mechanisms 400, 450 to have similar geometries, the first and second bodies 100, 200 can be separated from the third body 300 and re-attached to each other, as shown in FIG. 1A2.

Other configurations of the attachment mechanisms are equally applicable to the principles of the present inventive concepts.
