Various terms as used herein are defined below, and the definitions should be adopted when construing the claims that include those terms, except to the extent a different meaning is given within the specification or in express representations to the Patent and Trademark Office (PTO). To the extent a term used in a claim is not defined below or in representations to the PTO, it should be given the broadest definition persons having skill in the art have given that term as reflected in at least one printed publication, dictionary, or issued patent.

2. Selected Definitions

[0037] Certain claims include one or more of the following terms which, as used herein, are expressly defined below.

[0038] The term “ abut against ’ as used herein as a verb is defined as position adjacent and either physically touch or press against, directly or indirectly. After any abutting takes place with one object relative to another object, the objects may be fully or partially “abutted.” A first object may be abutted against a second object such that the second object is limited from moving in a direction of the first object. For example, a tube of a telescope shaft may have a radial face abutted against a first shell.

[0039] The term “ acute angle ” as used herein is defined as any angle that is less than 90 degrees. As depicted in some of the drawings herein, a zipper tape, that is linear in shape, has an upper edge that extends at an acute angle relative to a continuous upper edge of a shell. For example, in FIG. 1 and FIG. 3, zipper tapes 112a, 112b are coupled to sidewalls 110 of shells 102 and 104 in a spiral configuration that an upper edge of each of the zipper tapes 112a, 112b extends at an acute angle relative to upper edges of the sidewalls 110.

[0040] The term “align” as used herein is a verb that means manufacture, form, adjust, or arrange one or more physical objects into a particular position. After any aligning takes place, the objects may be fully or partially “aligned.” Aligning preferably involves arranging a structure or surface of a structure in linear relation to another structure or surface; for example, such that their borders or perimeters may share a set of parallel tangential lines. In certain instances, the aligned borders or perimeters may share a similar profile. Additionally, apertures may be aligned, such that a structure or portion of a structure may be extended into and/or through the apertures. [0041] The term “ aperture ” as used herein is defined as any opening in a solid object or structure, e.g., shell or a tube. For example, an aperture may be an opening that begins on one side of a solid object, e.g., shell or tube, and ends on the other side of the object. An aperture may alternatively be an opening that does not pass entirely through an object, but only partially passes through, e.g., as a groove. An aperture can be an opening in an object, e.g., first shell assembly or a tube, which is completely circumscribed, defined, or delimited by the object itself. Alternatively, an aperture can be an opening in the object when the object is combined with one or more other objects or structures. For example, a shell may have four sidewalls coupled to form an opening. An aperture or an opening may receive another object, e.g., a lock or travel -ware, and permit ingress and/or egress of the object through the aperture or an opening. An aperture may have a shoulder extending from the surface of the aperture.

[0042] The term “ assembly ” as used herein is defined as any set of components that have been fully or partially assembled together. A group of assemblies may be coupled to form an assembly or a solid body having an inner surface and an outer surface.

[0043] The term “clip” as used herein is defined as a device that can be removably coupled to another object. A clip may be referred to as a Delrin clip or a snap clip. A clip may be coupled to a strap.

[0044] The term “ coupled’’ as used herein is defined as directly or indirectly connected, attached, or unitary, e.g., part of. A first object may be coupled to a second object such that the first object is positioned at a specific location and orientation with respect to the second object. For example, two shorter shaft assemblies may be coupled to form a longer shaft assembly. A first object may be permanently, removably, or slidably coupled to a second object. Two objects may be permanently coupled to each other via sutures, adhesive, and/or press-fit. For example, a zipper tape may be sewn with sutures to a shell so that the zipper tape, in some cases, may not be uncoupled from the shell. Two objects may be removably coupled to each other via zipper tapes, latches, hooks, fasteners, locks, male and female connectors, clips, and/or clamps. In the case of zipper tapes, two zipper tapes are coupled to by meshing of teeth disposed on both the zipper tapes. For instance, a first shell and a second shell may be removably coupled with each other such that the first shell may then be uncoupled and removed from the second shell. Also, two objects may be capable of being slidably coupled together, e.g., where an inner diameter of one object is capable of receiving another object. Thus, a first tube having an inner diameter may be slidably coupled to a second tube having a smaller outer diameter. Furthermore, a first concentric support tube may be slidably coupled to a second concentric support tube.

[0045] The term “ cylindrical ” as used herein is defined as shaped like a cylinder, e.g., having straight parallel sides and a circular or oval or elliptical cross-section. A cylindrical body or structure, e.g., shaft, tube, or support tube, may be completely or partially shaped like a cylinder. A cylindrical body, e.g., shaft assembly, which has an outer diameter that changes abruptly may have a radial face, e.g., lip, rim, or flange (see, e.g., 102, 104, FIG. 1) extending toward the central axis of a cylindrical body. A cylindrical body may have an aperture that extends through the entire length of the body to form a hollow cylinder that is capable of permitting another body, e.g., concentric tube or pin, to pass through.

[0046] The term “edge” as used herein is defined as any line or border at which any surface terminates, or any line at which two surfaces of a solid object meet. For example, a shell may each have an inner surface and an outer surface forming an edge where the inner surface and the outer surface meet.

[0047] The terms “first” and “second” as used herein merely differentiate two or more things or actions, and do not signify anything else, including order of importance, sequence, etc. [0048] The term “ handle as used as a noun herein is defined as a structure configured to be gripped by a human hand. A handle may have a crossbar coupled to a telescopic shaft. A handle may have a telescopic shaft coupled to the cross bar to form the shape of a block-letter “T ” A handle may have a crossbar coupled to the two telescopic shafts. A handle may have a cross bar coupled to two telescopic shafts to form the shape of a block-letter “U ” A handle may have a telescopic shaft coupled to a second shell. A handle may have a telescopic shaft capable of extending away from and/or collapsing towards a second shell. A handle may have a telescopic shaft extending through a first shell. A handle may have two tubes disposed between a first shell and a second shell. A handle may have two tubes disposed between sidewalls of a first shell and a second shell.

[0049] The terms “he ” “she,” “they,” and any other personal pronouns as used herein refer to any gender interchangeably. For example, all uses of “he” encompasses “she” as well.

[0050] The term “lock” as used herein is defined as a structure for inhibiting movement of an object. A lock may be a ball, a pin, a bolt, a bar, cylinder, a rod, or any elongated structure. A lock may be extended through two aligned apertures disposed in two concentric tubes, respectively.

[0051] The term “ locked position ” as used herein is defined as inhibited from or inhibiting movement, e.g., of an object. For instance, a pin would be in a locked position when it inhibits movement of two or more concentric tubes relative to each other. Additionally, a pin would be in a locked position if the pin is extended through two tubes. Thus, the pin may inhibit movement of the tubes relative to each other. Conversely, the term “ unlocked position” as used herein is defined as a position of an object in which the object, some cases, does not inhibit movement of one object relative to another object. For instance, a pin would be in an unlocked position if it, in some cases, does not inhibit the movement of two or more concentric tubes relative to each other.

[0052] The term “luggage assembly” as used herein is defined as a structure capable of storing objects therein. A luggage assembly may be configured, sized, and shaped for be airplane stowage, e.g., carry-on luggage, or check-in luggage, for storing items such as clothing, shoes, and equipment. A luggage assembly may include a handle with telescopic shafts and wheels. A luggage assembly may be configured, sized, and shaped to be handheld, e.g., for storing items such as makeup, toiletries, pen, and pencils. Handheld luggage assemblies may be referred to as carrying case assemblies. Examples of a carrying case assembly may include travel bag, backpack, knapsack, gym bag, purse, and fanny pack.

[0053] The term “ provide ” as used herein is defined as make available, furnish, supply, equip, or cause to be placed in position.

[0054] The term “perpendicular” as used herein is defined as at an angle ranging from 85° or 88 to 92° or 95°. Two structures that are perpendicular to each other may be orthogonal and/or tangential to each other.

[0055] The term “ separated ’ as used herein is defined as positioned a distance apart, e.g., not touching. Two separated objects or structures have no portions coupled to, e.g., touching, each other. For example, a first shell and a second shell may be separated from each other if no portion of the first shell is coupled to any portion of the second shell.

[0056] The term “shell” as used herein means an outer cover, e.g., configured for protection or concealment of an object. A shell may have a base and four sidewalls extending from the base. The base and four sidewalls may be unitary. Furthermore, the base and four sidewalls may be formed, e.g., mold, woven, or carved, from a single piece, e.g., of plastic, carbon fiber, Kevlar, metal, or wood. A shell may be removably coupled to another shell via latches, buckles, clamps, hooks, straps, cords, rope, string, and/or hinges. A shell may have an upper portion and a lower portion removably coupled to the upper portion. A shell may be rigid. A shell may have a first rigid portion and a second pliable portion, e.g., flap or sidewall.

[0057] The term “ sidewalF as used herein is defined as any structure that is part of one of the shells of a luggage assembly to which certain parts of the zipper tape, e.g., the zipper tape sections, are preferably parallel. Preferably each of the shells disclosed herein includes four sidewalls each having inner and outer surfaces, which can be either planar, i.e., flat, or slightly curved. A sidewall with flat (planar) inner and outer surfaces is part of the shells shown in the drawings herein. When viewed in cross-sectional profile, the sidewalls may have polygonal cross-sections, e.g., triangular, rectangular, pentagonal, hexagonal, or octagonal. Alternatively, each shell may have a single curved sidewall that forms a circle. A sidewall may be rigid. A sidewall may be pliable. [0058] The term “ spiral configuration” as used herein is defined as a configuration of structure(s) in the form of a spiral. For example, a spiral configuration can be the configuration of a single unitary structure with multiple parts that form geometrical structures within other geometrical structures, e.g., partially open rectangles disposed inside other partially open rectangles, exemplified by the zipper tape in FIGS. 1 and 2A that spirals inward by virtue of the multiple adjoining sections. As another example, a spiral configuration multiple structures that are coupled together to form a closed geometrical structure, e.g., sidewalls that are disposed in the form of rectangles. Expressed in another way, at least one type of spiral configuration is a configuration including one or more clockwise or counter-clockwise turns of the structure(s), when viewed from above, in a turn is a change in direction, preferably 90 degrees, in which the turns combine to total at least 360 degrees, without an intersection. An object or structure having a spiral configuration may be wound around a center point gradually receding from or approaching the center. A spiral configuration is preferably rectangular, but more broadly may have a profile of any geometric shape. A spiral configuration may follow a 2-dimensional path, e.g., along a X-axis and Y-axis. A spiral configuration may follow a 3-dimensional path, e.g., on X-axis, Y-axis, and Z-axis. An object having a spiral configuration may have one or more “spiral layers. ” As used herein, a full spiral layer is a combination of structures, e.g., sections of a zipper tape, having turns that combine to be at least 360 degrees. For example, a zipper tape extending around a central axis, such that the zipper tape overlaps itself, may form one spiral layer that has one or more turns adding up to 360 degrees, and then when the zipper tape extends in a spiral configuration further, may have additional turns that combine to 540 degrees. Accordingly, a zipper tape may be said to have a spiral configuration with 540 degrees of turns if the zipper overlaps itself and has multiple spiral layers with turns combined to be 540 degrees. An object or structure may have a spiral configuration with turns totaling 360 degrees, 450 degrees, 540 degrees, 630 degrees, 720 degrees, 810 degrees, or more.

[0059] The term “strap” as used herein is defined as a flexible structure that has a long side and at least one short side and may be rectangular in overall shape as viewed from the top or bottom. A strap may be rectangular in cross-section. A strap may be continuous. A strap may be constructed from any one of various materials, e.g., leather, Kevlar, cotton, and/or hemp. A strap may be folded into two or more adjacent portions or segments. Certain straps disclosed herein have segments folded into plies that are sutured together. A strap may have a portion coupled to a shell, tabletop, a shelf, and/or a portion of a clip.

[0060] The term “ surface ” as used herein means any face of a structure. A surface may also refer to that flat or substantially flat area of a structure, for example, a shell, a flap, an expansion curtain, a tabletop, or a shelf. A surface may also refer to that flat or substantially flat area that extend radially around a cylinder which may, for example, be part of a telescopic shaft, a tube, a shaft, a crossbar, a bracket, or a sleeve. A surface may have irregular contours. A surface may be formed from components, e.g., shell, flap, expansion portion, tabletop, bracket, and/or shelf, coupled together. Coupled components may form irregular surfaces. [0061] The term “ tapered ” as used herein is defined as extending from a first point to a second point while become progressively smaller, e.g., in radius, and/or thinner from the first point to the second point. Structures that are tapered may have a profile that is beveled, frustoconical, and/or conical. Structures that are tapered may be cylindrical.

[0064] The term “ threaded ” as used herein is defined as having threads. Threads may include one or more helical protrusions or grooves on a surface of a cylindrical object. Each full rotation of a protrusion or groove around a threaded surface of the object is referred to herein as a single “thread.” A threaded assembly may include a “threaded portion” wherein a section of the threaded assembly includes threads. A threaded portion may have a diameter sized to extend through an aperture of a module coupler body. In certain cases, a threaded portion of a structure may be removably coupled to a threaded assembly.

[0065] The term “tube” as used herein is defined any structure having an inner surface and an outer surface. A tube may have an aperture disposed therethrough. Preferably, a tube is cylindrical. However, any or all tubes of an assembly, e.g., shaft, telescopic shaft, crossbar, or sleeve, may have polygonal cross-sections, e.g., triangular, rectangular, pentagonal, hexagonal, or octagonal.

[0066] The term “ unitary ” as used herein is defined as having the nature, properties, or characteristics of a single unit. For example, a base and sidewalls that are individual parts of a shell are unitary in the sense they are not separate but rather are formed, e.g., mold or carved, from a single piece of material, e.g., of fabric, plastic, carbon fiber, metal, or wood.

[0067] The terms “upper,” “lower,” “top,” “ bottom ” as used herein are relative terms describing the position of one object, thing, or point positioned in its intended useful position, relative to some other object, thing, or point also positioned in its intended useful position, when the objects, things, or points are compared to distance from the center of the earth.

4. Specific Embodiments in the Drawings

[00107] The drawings presented herein are for illustrative purposes only and do not limit the scope of the disclosure or claims. Rather, the drawings are intended to help enable one having ordinary skill in the art to make and use the disclosed assemblies and practice the methods disclosed herein.

[00108] This section addresses specific versions of expandable luggage assemblies in the drawings, which include assemblies, elements and parts that can be part of one or more expandable luggage assemblies and methods for storing travel-ware. Although this section focuses on the drawings, and the specific embodiments found in those drawings, parts of this section may also have applicability to other embodiments not shown in the drawings. The limitations referenced in this section should not be used to limit the scope of the claims themselves, which have broader applicability than the structures disclosed in the drawings. [00109] FIG. 1 illustrates a perspective view of a luggage assembly 100 having a first shell 102 and a second shell 104 that are separated. FIGS. 2A-D illustrate profile views of the first shell 102 and the second shell 104 having various portions coupled. For purposes of illustration FIG. 1 and FIGS. 2A-D have slightly differing zipper tape 114a, 114b arrangements. However, FIG. 1 and FIGS. 2A-D are related.

[00110] The luggage assembly 100 includes a handle 106 coupled to the second shell 104. The upper edges of the first shell 102 and second shell 104 may be removably coupled to form an enclosure, e.g., using the zippers as described herein. Shelves and travel-ware (not shown), e.g., clothing, make-up, and personal accessories, may be stored in the enclosure, e.g., when the outer edges of the first and second shells are coupled.

[00111] The first shell 102 has a first base 108a and has four first sidewalls llOa-d extending from the first base 108a and each of the four first sidewalls llOa-d has: a lower edge that is coupled to, and preferably adjoins, a part of the base 108a; an upper edge that may be coupled to or with an upper edge of a sidewall of the second shell 104, as described below; and two side edges each of which adjoins a side edge of another first sidewall 110, preferably as part of a unitary shell. That is, the four first sidewalls llOa-d may be unitary, albeit preferably arranged as sides of a rectangle. Preferably, each first sidewall 110 is planar and is perpendicular, e.g., orthogonal or tangential, to a plane of the first base 108a. Thus, the first base 108a and the first sidewalls llOa-d may form a cube or a rectangular prism that has a first opening 112a., through which a user of the luggage assembly 100 can insert items such as travel-ware before the first and second shells are coupled together, e.g., closed, to form an enclosure.

[00112] Referring to FIG. 1 and FIG. 2A, one section of a first zipper tape 114a is coupled to the first sidewalls llOa-d. In that illustrated embodiment, the first zipper tape 114a is a planar strip of flexible material such as cloth and that first zipper tape 114a preferably has a variable overall width, e.g., such that certain parts of the first zipper tape 114a have a greater width than other parts. However, in other specific embodiments (not illustrated in the drawings), the overall widths of either or both of the zipper tapes are uniform. The first zipper tape 114a includes multiple sections. For example, in FIGS. 1 and 2A the first zipper tape 114a has a first section 115a that is disposed parallel to, and at least partly also coupled directly to, the sidewall llOd. In at least one embodiment, those sections 115a-d may be referred to as the “outer sections” of the first zipper tape 114a. As described more fully below, the first zipper tape 114a also includes sections 115e- h (“middle sections”) with planar surfaces that are parallel to and coupled (directly or indirectly) to the planar surfaces of the respective outer sections, after being wound into a spiral configuration. Additionally, the zipper tape 114a further includes sections 115i-l (“inner sections”) with planar surfaces that are parallel to and coupled (directly or indirectly) to the planar surfaces of the respective middle sections, after being wound into a spiral configuration. The zipper tape sections 115i-l, and section 115m, are referred to herein as the “inner sections” because they are closer than the “middle sections” to the central part of the space inside the enclosure of the luggage assembly 100. As shown in FIG. 1, the first zipper section 115m may be referred to herein as the “free end,” is not coupled to the first shell 102. The uncoupled section 115m has a pin 116a coupled thereto.

[00113] The first zipper tape 114a includes a first stopper 118a at the other end of the first zipper tape 114a, which may be referred to herein as the “anchor end,” which is coupled to the first shell 102. As shown in FIG. 1, the first zipper tape 114a includes first zipper teeth 120a that are disposed on the upper edge of the first zipper tape 114a. The first zipper teeth 120a extends from the first stopper 118a, proximate the anchor end of the first zipper tape 114a, to the first pin 116a, proximate the free end of the first zipper tape 114a.

[00114] As shown in FIG. 1, the total length of the first zipper tape 114a is preferably at least two times the combined length of the sidewalls llOa-d. Thus, there are at least four outer sections 115a-d, four middle sections 115e-h, and five inner sections 115i-m, wherein the outer section 115a (e.g., the section that includes a stopper 118a on the anchor end) is shorter than, and preferably approximately half as long as, the corresponding sidewall 110a, and the inner section 115m(which includes the first pin 116a) with a portion coupled the first shell 102 (not the free end portion) is shorter than the corresponding sidewall. Preferably, while the luggage assembly 100 is being assembled, the first zipper tape 114a is arranged, e.g., coiled, so that different sections of the first zipper tape 114a overlap other sections of the first zipper tape 114a, thus forming a spiral configuration, which is formed before or while being attached or otherwise coupled to the first shell 102a during the assembling process. Accordingly, as discussed above, the first zipper tape 114a in FIG. 1 includes four outer sections 115a-d, four middle sections 115e-h, and five inner sections 115i-m. Some specific embodiments of the luggage assembly 100 may each include a first zipper tape 114a having four outer sections 115a-d, four middle sections 115e-h, and four inner sections 115i-k (see FIG. 2D). Other specific embodiments of the luggage assembly 100 may each include first zipper tape 114a having only outer sections and inner sections, e.g., four outer sections and four inner sections. Accordingly, after certain sections of the first zipper tape 114a are coupled to corresponding inner surfaces of the first sidewalls llOa-d and other sections are the disposed in an overlapping arrangement, the first zipper tape 114a after being incorporated into the luggage assembly 100 has a spiral configuration. When using the first zipper tape 114a that is part of the luggage assembly 100, a user may slide a zipper slider from the first stopper 118a along the spiral path of the first teeth 120a on the first zipper tape 114a, the first teeth 120a extend at an acute angle as the spiral path extends away from the first stopper 118a to the first pin 116a. In other words, the first zipper tape 114a spirals outward, away from first shell 102.

[00115] Thus, the first zipper tape 114a has a spiral configuration having at least two spiral layers 122a, 122b. Starting from the first stopper 118a comer of the sidewalls 110a, llOd and going counterclockwise, one spiral layer is formed when the first zipper tape 114a makes four turns that add up to at least 360 degrees within the first shell 102. As shown in FIG. 1, the four first sidewalls llOa-d have four rounded corners that each makes 90 degree turns, adding up to at least 360 degrees. Accordingly, the first zipper tape 114a has eight turns which add up to at least 720 degrees. Starting from the stopper 118a, the first spiral layer 122a is coupled to the sidewalls llOa-d. The second spiral 122b is coupled, e.g., via suture, to the first spiral layer 122a. Additionally, the second spiral layer 122b may be coupled, e.g., via suture, to the sidewalls 110a- d, with or without being coupled to the first spiral layer 122a.

[00116] The second shell 104 has a second base 108b and has four second sidewalls llOa’-d’ extending from the second base 108b. The four second sidewalls llOa’-d’ may be unitary. Preferably, each second sidewall 110’ is perpendicular, e.g., orthogonal or tangential, to a plane of a second base 108b. Thus, second base 108b and the second sidewalls llOa’-d’ may form a cube or a rectangular prism that has a second opening 112b.

[00117] A second zipper tape 114b includes sections and spiral layers that are preferably arranged in the same way the sections of the first zipper tape 114a are arranged, as discussed above and as shown in FIG. 1. The second zipper tape 114b is coupled to the second sidewalls llOa’-d’ of the second shell 104, with the outer surfaces of the outer sections 115a’-d’ of the second zipper tape 114b preferably coupled directly to the inner surfaces of the second sidewalls llOa’-d’. The second zipper tape 114b is coupled to edges of the second sidewalls llOa’-d’. Moreover, the second zipper tape 114b is coupled to inner surfaces of the second sidewalls llOa’-d’. However, a portion of the second zipper tape 114b is not coupled to the second shell 104. The uncoupled portion of the first zipper tape 114b, specifically the free end that has a second pin 116b coupled thereto. The second pin 116b is capable of being aligned with the pin 116a. of the first zipper tape 114a. Additionally, the second pin 116b has a stopper portion (not shown) at the free end that is capable of being abutted against the second zipper slider126b, which inhibits that second pin 116b from being pulled out of the second zipper slider 126b.

[00118] The second zipper tape 114b includes second stopper 118b and second zipper teeth 120b couplecoupled to the upper edge of the first second zipper tape 114b. The second zipper teeth 120b extends from the stopper 118b to the second pin 116b. Furthermore, the second zipper tape 114b includes a first zipper slider126a and second zipper slider126b coupled to the second zipper teeth 120b and the second pin 116b. The first zipper slider 126a and the second zipper slider 126b are capable of being slid along the second zipper teeth 120b. However, the stopper 124 second pin 116b inhibits the first zipper slider 126a and the second zipper slider 126b from being slid off of the second zipper tape 114b. Additionally, the first zipper slider 126a and the second zipper slider 126b are capable of having the pin 116a extend therethrough.

[00119] BecauseDue to the pin 116a isbeing capable of being removably coupled to the first zipper slider 126a and the second zipper slider 126b, the first shell 102 and the second shell 104 are capable of being separated from each other.

[00120] As shown in FIG.1, the length of the second zipper tape 114b is at least threetwo two three times the circumferencecombined distance of the second sidewalls llOa’-d’. Accordingly, when coupled to the inner surfaces of the second sidewalls llOa’-d’ and overlapping itself, the second zipper tape 114b has a spiral configuration within the second opening 112b., essentially like the spiral configuration of the first zipper tape 114a as described above. Starting with the second stopper 118b and following the spiral path of the second zipper teeth 120b on the second zipper tape 114b, the second teeth 120b extend at an acute angle as the spiral path extends away from the second stopper 118b, the second teeth 120b extend on a line that at an angle relative to the upper edge of the second shell 104. . In other words, the second zipper tape 114b spirals outward, away from second shell 104.

[00121] Additionally, the second zipper tape 114b has a spiral configuration having at least two spiral layers 122a’, 122b’ much like the first zipper tape 114a has a spiral configuration has at least two spiral layers 122a, 122b composed of sections having the same relationship with other sections as those sections that form part of the first zipper tape 114a. Starting from the second stopper 118b and going clockwise, one spiral layer is formed when the second zipper tape 114b makes four turns that add up to at least 360 degrees within the second shell 104. As shown in FIG. 1, the four second sidewalls llOa’-d’ have four rounded comers that each makes 90 degree turns, adding up to at least 360 degrees. Accordingly, the second zipper tape 114b has eight turns which add up to at least 720 degrees. Starting from the second stopper 118b, the first spiral layer 122a’ is coupled to the second sidewalls llOa’-d’. The second spiral 122b’ is coupled, e.g., via suture, to the first spiral layer 122a’. Additionally, the second spiral 122b’ may be coupled, e.g., via suture, to the second sidewalls llOa’-d’, with or without being coupled to the first spiral layer 122a’

[00122] The first shell 102 has two wheels. The shell 104 also has two wheels. The wheels may be coupled to a respective outer surface of the first shell 102 and the second shell 104 as depicted in the drawings. Preferably, each wheel 118 is coupled to respective sidewall 110 of the first shell 102 and the second shell 104.

[00123] Referring to FIG. 1 and FIGS. 2A-C, a user may couple a first shell 102 and a second shell 104 of a luggage assembly 100 as follows. First, the user extends a first pin 116a through a first zipper slider 126a and a second zipper slider 126b, and then aligns the first pin 116a with a second pin 116b. Next, the user may pull on the first zipper slider 126a to couple portions of first zipper teeth 120a and the second zipper teeth 120b. Although the drawings indicate that the first zipper slider 126a and the second zipper slider 126b are pulled up or down, it should be understood they can be pulled left or right if the luggage assembly 100 is laid horizontally. The user may pull the first zipper slider 126a along the spiral configuration of the first zipper teeth 120a and the second zipper teeth 120b turning a total of at least 360 degrees, which would couple respective second spiral layers 122b, 122b’ (see FIG. 2B). Thus, the luggage assembly 100 would be in a partially collapsed configuration. The user may further pull the first zipper slider 126a along the spiral configuration of the first zipper teeth 120a and the second zipper teeth 120b another 360 degrees, which would couple respective first spiral layers 122a, 122a’ (see FIG. 2B). Thus, the luggage assembly 100 would by fully collapsed once at least 720 degrees of turns are made with first zipper slider 126a.

[00124] While the luggage assembly 100 is in the partially collapsed configuration, if the user needs to access content from inside the luggage assembly 100 (where the second spiral layers 122b, 122b’ are coupled and the first spiral layers 122a, 122a’ are not), the user may uncouple (with the first zipper slider 126a) a portion or all of the second spiral layers 122b, 122b’ until the second zipper slider 126b is exposed. Next, the user may pull the second zipper slider 126b towards the first zipper slider 126a. As the second zipper slider 126b is pulled, respective portions of the first teeth 120a and the second teeth 120b are uncoupled. Thus, the user is opening the luggage assembly 100 from both ends when pulling the first zipper slider 126a and the second zipper slider 126b towards each other. When respective portions of the second spiral layer 122b, 122b’ are uncoupled where the first zipper slider 126a and the second zipper slider 126b aligned on respective sidewalls, e.g., 110b, 110b’, of the first shell 102 and the second shell 104, the user may lay first shell 102 and the second shell 104 flat, like a clam shell, to access content inside the luggage assembly 100. [00125] Rather accessing content inside the luggage assembly 100, the user may prefer to fully collapse the luggage assembly 100 from the partially collapsed configuration, the user may further pull the first zipper slider 126a along the spiral configuration of the first zipper teeth 120a and the second zipper teeth 120b 360 degrees turning another 360 degrees, which would couple respective first spiral layers 122a, 122a’ (see FIG. 2C). Thus, the luggage assembly 100 would by fully collapse once at least 720 degrees of turns are made with first zipper slider 126a.

[00126] As the user couple more of the first spiral layers 122a, 122a’, the luggage assembly 100 collapses, reducing in volume. Reducing its volume reduces the space needed for the luggage assembly 100 to occupy in cramped airplane luggage compartments. Conversely, as the user uncouples first spiral layers 122a, 122a’ and then the second spiral layers 122b, 122b’, the luggage assembly 100 expands, increasing in volume. The increase in its volume allows the luggage assembly 100 to store more travel ware as needed.

[00127] To uncouple the first shell 102 and the second shell 104, the user may perform the steps discussed above in reverse.

[00128] Referring to FIG. 2D, if the user needs to access content from inside the luggage assembly 100 that is in a fully collapsed configuration (where all spiral layers 122 are coupled), the user may uncouple (with the first zipper slider 126a) the first spiral layers 122a, 122a’ and a portion of the second spiral layers 122b, 122b’ until the second zipper slider 126b is exposed. Next, the user may pull the second zipper slider 126b towards the first zipper slider 126a. As the second zipper slider 126b is pulled, respective portions of the first teeth 120a and the second teeth 120b are uncoupled. Thus, the user is opening the luggage assembly 100 from both ends when pulling the first zipper slider 126a and the second zipper slider 126b towards each other. When the first spiral layer 122a, 122a’ are uncoupled and respective portions of the second spiral layer 122b, 122b’ are uncoupled where the first zipper slider 126a and the second zipper slider 126b aligned on respective sidewalls, e.g., 110b, 110b’, of the first shell 102 and the second shell 104, the user may lay first shell 102 and the second shell 104 flat, like a clam shell, to access content inside the luggage assembly 100.

[00129] FIG. 3 and FIGS. 4A-D illustrate handheld carrying case assemblies 300 that do not include any handle or wheels. All other components and labels of the carrying case assemblies of FIG. 3 and FIGS. 4A-D correspond to those of the luggage assemblies of FIG. 1 and FIGS. 4A- D. Thus, the description and operation of the luggage assemblies of FIG. 1 and FIGS. 4A-D are applicable to the carrying case assemblies 300 in FIG. 3 and FIGS. 4A-D.

[00130] Although the above discussion of opening and/or closing luggage assemblies 100 and carriage assemblies 300 corresponds to figures showing luggage assemblies 100 and carriage case assemblies 300 in upright positions (see FIGS. 2A-C and FIGS. 4A-C), it should be understood that opening and/or closing any luggage assembly 100 or any carriage case assembly 300 can be accomplished by having them laid on a base 108 of a first shell 102 or of a second shell 104. [00131] FIG. 5A illustrates a perspective view of a detachable suitcase 5300. The detachable suitcase 5300 includes front shell 5306 and back shell 5308. The front shell 5306 and back shell 5308 may be coupled to form an enclosure for storage or travel-ware, e.g., clothing and personal accessories. The front shell 5306 may be removably coupled to the back shell 5308, e.g., via zipper assembly 6308.

[00132] Referring to FIGS. 5A-C, the front shell 5306 may be removably coupled to the back shell 5308, e.g., via zipper assembly 6308. The first zipper tape 5312a may be coupled to the front shell 5306. The first zipper tape 5312a may be coupled to the edges of the front shell 5306.

[00133] The first zipper tape 5312a may be removably coupled to the second zipper tape 5312b. The second zipper tape 5312b may be coupled to the back shell 5308. In addition, the second zipper tape 5312b may be coupled to the edges of the back shell 5308. The zipper tapes 5312a, 5312b may extend parallel to each other. Each of zipper tapes 5312a, 5312b may form a ring or a loop around their respective shells 5306, 5308.

[00134] The first zipper tape 5312a includes teeth 6507, a pin 6506a and a top stop 6505a. The second zipper tape 5312b includes teeth 6507, a pin 6506b, two single pull key lock sliders 6504a, 6504b and a top stop 6505b. The pin 6506a of the first zipper tape 5312a may be coupled the two single pull key lock sliders 6504a, 6504b.

[00135] As shown in FIG. 5A, the pin 6506a of the first zipper tape 5312a may be coupled the two single pull key lock sliders 6504a, 6504b. The single pull key lock slider 6504a may be pulled away from one end of the single pull key lock slider 6504b around the edges of the front shell 5306 and the back shell 5308. However, the single pull key lock slider 6504b may be pulled away from the pins 6506a, 6506b around the edges of the front shell 5306 and the back shell 5308 before the single pull lock slider 6504a reaching the full loop and overlapping the zipper tapes 5312a, 5312b. The single pull key lock sliders 6504a, 6504b may fully close and lock the detachable suitcase 5300 at multiple points within the overlapped segments of the zipper tapes 5312a, 5312b.

[00136] Referring to FIGS. 6A-B, the single pull key lock slider 6504b may move from the zipper tapes 5312a, 5312b being overlapped toward the overlapping zipper tapes 5312a, 5312b and allow the detachable suitcase 5300 to be opened at the side 5408a. [00137] Referring to FIG. 6A, the single pull key lock slider 6504a may follow the single pull key lock slider 6504b to the side 5408b and move the attachment to the side 5408b and allow the detachable suitcase 5300 to be opened at the side 5408b.

[00138] Referring to FIG. 6B, the single pull key lock slider 6504a may follow the single pull key lock slider 6504b to side 5408c and move the attachment to the side 5408c and allow the detachable suitcase 5300 to be opened at the side 5408c.

[00139] Referring to FIGS. 5A-B, the single pull key lock slider 6504a may follow the single pull key lock slider 6504b to side 5408d and move the attachment to the side 5408d and allow the detachable suitcase 5300 to be opened at the side 5408d.

[00140] In another embodiment of the invention depicted in FIGS. 5A-B, the zipper tapes 5312a, 5312b may have no overlapped segments the pin 6506a of the first zipper tape 5312a may be coupled the two single pull key lock sliders 6504a, 6504b. The single pull key lock slider 6504a may be pulled away from one end of the single pull key lock slider 6504b as shown in FIG. 5C and meet the single pull key lock slider 6504b again at the opposite end of the single pull key lock slider 6504b to allow the detachable suitcase 5300 fully closed and locked.

[00141] Basically, the single pull key lock slider 6504a may be pulled away from one end of the single pull key lock slider 6504b around the edges of the front shell 5306 and the back shell 5308 in one full loop with no overlapped segments. The single pull key lock sliders 6504a may only mate and lock together with the single pull key lock slider 6504b after it has moved one full loop. Since there are no overlapped segments, the single pull key lock slider 6504a, 6504b may only fully close and lock the detachable suitcase 5300 at a single point at the end of the full loop; whereas the single pull key lock slider 6504a, 6504b may fully close and lock the detachable suitcase 5300 at multiple points within the overlapped segments of the zipper tapes 5312a, 5312b as mentioned in the previous embodiment. However, the new embodiment still allows the detachable suitcase 5300 to be opened at any side 5408a, 5408b, 5408c, 5408d with the attachment being moved from one side to another as mentioned in the previous embodiment. [00142] In another embodiment of the invention depicted in FIG. 5B the zipper tapes 5312a, 5312b include the fully overlapped loop instead of partially overlapped loop in segments or no overlapped loop as mentioned in two previous embodiments. The pin 6506a of the first zipper tape 5312a may be coupled the two single pull key lock sliders 6504a, 6504b. The single pull key lock slider 6504a may be pulled away from one end of the single pull key lock slider 6504b around the edges of the front shell 5306 and the back shell 5308.

[00143] However, the single pull key lock slider 6504b may be pulled away from the pins 6506a, 6506b around the edges of the front shell 5306 and the back shell 5308 before the single pull lock slider 6504a reaching the full loop and overlapping the zipper tapes 5312a, 5312b. The single pull key lock sliders 6504a, 6504b may fully close and lock the detachable suitcase 5300 anywhere within the fully overlapped loop instead of multiple points within overlapped segments of the zipper tapes 5312a, 5312b or only single point at the end of the loop as mentioned in the previous embodiments. This embodiment also allows the detachable suitcase 5300 to be opened at any side 5408a, 5408b, 5408c, 5408d and at any point with the attachment being moved from one side to another as mentioned in the previous embodiments.

[00144] Referring to FIGS. 5C-5D, the embodiments also depict the detachable suitcase with the fully overlapped zipper can expand the suitcase without the need of a separate expandable zipper as shown in FIG. 5D. The spiral fully overlapped zipper allows the inner second half of the zipper to expand the detachable suitcase by enlarging the width of the fabric part of the inner second half of the zipper tape by attaching, weaving or sewing the additional fabric 6308b along the outside edges of the fabric part of the zipper tape. As shown in FIG. 5C, the detachable suitcase is not expandable because the width of the spiral fully overlapped zipper half attached with stiches to the edge of the back shell 5308 is the same throughout. As shown in FIG. 5D, the detachable suitcase is expandable because the width of the spiral fully overlapped zipper half attached with stiches to the edge of the back shell 5308 is wider in the inner half of the zipper half. As shown in FIG. 5D, the stich pattern on the zipper half is more complex than the ones shown in FIG. 5C. The reason for the difference due to no additional fabric is attached, weaved or sewn to the outside edge of the fabric part of the zipper half. Only the outer half of the zipper half is attached with stiches to the edge of the back shell 5308; the inner half of the zipper half is attached with stiches to the outer half of the zipper half and resulting part of the outer half of the zipper half is used to increase the width of the inner half of the zipper half and allow to expand the detachable suitcase.

[00145] Referring to FIG. 7A, the back shell 5308b may be removably coupled to the expandable segment 5308d via zipper tape 5312e and zipper tape 5312i. The zipper tape 5312e may be coupled to the back shell 5308b. The zipper tape 5312e may be coupled to the edge of the back shell 5308b. The zipper tape 5312e may be removably coupled to the zipper tape 5312i. The zipper tape 5312i may be coupled to the expandable segment 5308d. In addition, the zipper tape 5312i may be coupled to the edge of the expandable segment 5308d. The spiral nature of the overlapped zipper tape allows the slider 6504i of the zipper tape 5312i to be hidden inside the detachable suitcase without the need for the lock.

[00146] The front shell 5306 may be removably coupled to the back shell 5308b with the expandable segment 5308d via zipper tape 5312a and zipper tape 5312h. The zipper tape 5312a may be coupled to the front shell 5306. The zipper tape 5312a may be coupled to the edge of the front shell 5306. The zipper tape 5312a may be removably coupled to the zipper tape 5312h. The zipper tape 5312h may be coupled to the expandable segment 5308d. In addition, the zipper tape 5312h may be coupled to the edge of the expandable segment 5308d.

[00147] FIG. 7B illustrates a perspective view of the interior compression system that consists of straps 5513 and detachable zippered compartments 5501 with compression flaps 5501a. The end portions 5513c of straps 5513 with Velcro strips sewn on both surfaces of the end portions 5513c of the straps are securely attached to the bottom walls of the shells 5306, 5308b of the detachable suitcase by being sandwiched between two Velcro strips 5513a, 5513b with the bottom Velcro strips 5513b securely glued to the bottom walls of the shells 5306, 5308b. The zippered compartments 5501 can be detached for maximum compression by tightening two straps 5513 with the help of the detachable compression flaps 5501a around near both ends of detached zippered compartments 5501. If the zippered compartments 5501 are partially filled with personal belongings, the same straps 55013 mentioned above can secure the personal belongings from shifting by fitting through the openings 5501b near the bottoms of the zippered compartments 5501 and strapping the personal belongings inside the zippered compartments 5501. [00148] Referring to FIGS. 7C-D, the zippered compartments 5501 may not be detached for maximum compression by adding an expandable segment 5308t just below the compression flap 5501a and adding two openings 5501b on each side of the expandable segment 5308t and each openings 5501b is vertically above the openings 5501b at the bottom of the zipper compartment 5501. The straps 5513, which are already inside the zipper compartment 5501 after fitting through the openings 5501b near or at the bottom of the zippered compartment 5501, are now fitting through the openings 5501b on the sides of the expandable segment 5308t to the outside of the zipper compartment 5501. The maximum compression can be applied to the zipper compartment 5501 by tightening two straps 5513 with the help of the detachable compression flaps 5501a around near both ends of detached zippered compartments 5501 without having the zippered compartments 5501 detached. If the zippered compartments 5501 are partially filled with personal belongings, the same straps 5513 can secure the personal belongings from shifting by fitting through the openings 5501b at the expandable segment 5308t back inside the zippered compartments 5501 and strapping the personal belongings inside the zippered compartments 5501. [00149] Referring to FIGS. 8A-B the hard-shell expandable segment 5308d allows the expanded detachable suitcase 5300 to accommodate shelving units 5502, 5503.
