In some examples, the cover may have a thickness that changes or varies as the cover extends between the rear bottom edge of the bag and the front edge of the bag. In some examples, the thickness of the cover may gradually decrease as the cover extends from the rear bottom edge of the bag to the front edge of the bag.

[0091] Handle assembly In some embodiments, the bag may include a handle assembly. In some embodiments, the handle assembly may include a handle 620 for operating the bag. In some embodiments, the handle assembly may include a plurality of support members attached to the handle 620.

[0092] In some examples, the handle 620 may have a retractable handle that can extend upward and / or retract downward. In some examples, the handle 620 may be configured to be stored within a partially enclosed area formed between the outer surface of the bag and the cover 610 surrounding the outer surface of the bag. In some examples, the handle assembly may be located (i) outside the internal area of ​​the bag and (ii) between the back surface and the inner surface of the cover so that the handle assembly can be stored within a partially enclosed area provided between the cover and the outside of the bag.

[0093] tolerance In some examples, the support members of the handle assembly may include a set of members that are telescopically positioned to facilitate the extension and retraction of the handle. In some examples, the set of members may be housed within a housing that is sized and shaped to accommodate the set of members. In some examples, the housing may be located between the back surface of the bag and a cover surrounding the outer surface of the bag. In some examples, the set of members may be extendable from the housing to deploy the handle.

[0094] In some examples, a set of components may be sized and shaped to minimize or reduce the spacing or gaps between components arranged in a retractable manner. In some examples, the set of components and the interior of the housing may be sized and shaped to minimize or reduce the spacing or gaps between components arranged in a retractable manner and the interior of the housing.

[0095] In some examples, the spacing or gap may be reduced and tightened within a predetermined tolerance that allows the handle and support member to remain in a fixed position and / or fixed orientation when the object applies force to the handle or otherwise operates the handle to operate the bag. In some examples, the spacing or gap may be configured to reduce or eliminate any swing of the handle or support member relative to the rest of the housing or bag when the handle and support member are deployed extending upward.

[0096] In some examples, the spacing or gaps may still allow a set of members to (i) translate relative to each other and (ii) fold or be stored within the housing, so that the handle can simply drop from the extended position to the fully retracted position with minimal user input. For example, in some examples, the handle may be configured such that when the object engages with a pressure-sensitive actuator associated with the handle assembly to disengage any mechanical or physical lock that holds the handle in the extended position, the handle drops from the extended position to the fully retracted position without any other manual or physical input from the object beyond the engagement of the pressure-sensitive actuator.

In some examples, the adjustable loop may be loosened to release one or more articles or articles so that the articles can be repositioned or removed from the internal area of ​​the bag.

[0138] External strap In some embodiments, the bag 1000 may include one or more external straps 1340 extending laterally or longitudinally across the height, length, and / or width of the bag 1000. In some examples, one or more external straps 1340 may be attached to the external surface of the bag 1000 to reinforce the bag. In some examples, one or more external straps 1340 may be attached to the external surface of the bag 1000 to distribute or redistribute forces or loads applied to the bag.

[0139] In some examples, one or more external straps 1340 may include one or more lateral straps configured to reinforce the bag against radial expansion so that the bag can resist tearing or bursting. In some examples, the lateral straps may be positioned around the perimeter of the bag. In some examples, the lateral straps may extend circumferentially around the bag. In some examples, the lateral straps may include one or more complementary fasteners that can be joined together to form a closed loop configuration. In some examples, the closed loop configuration may be adjusted by adjusting the tension level of the lateral straps by applying or releasing tension to the lateral straps or by operating one or more fasteners.

[0140] In some examples, one or more external straps 1340 may include one or more longitudinal straps configured to distribute or redistribute various forces or loads applied to the bag. In some examples, the one or more longitudinal straps may be configured to transmit forces or loads applied to a first part or section of the bag to a second part or section of the bag. In some examples, the first part or section of the bag may include a part or section of the bag that is susceptible to damage when a force or load exceeding a predetermined threshold is applied to the first part or section of the bag. In some examples, the second part or section of the bag may include another part or section of the bag that can withstand such forces or loads exceeding a predetermined threshold when applied to the second part or section of the bag.

[0141] In some examples, one or more external straps 1340 may be attached to or connected to the bag's handle. In some examples, the handle may be positioned on or along the top of the bag. In some examples, when a user or object pulls the top handle of the bag, one or more external straps 1340 may be configured to transmit the tensile force applied to the handle to another part of the bag to which the external straps are attached or connected. For example, in some examples, one or more external straps 1340 may be configured to transmit the tensile force to the base portion of the bag and / or to a cover piece attached to the bag. In some examples, one or more external straps 1340 may be configured to transmit the tensile force away from the body of the bag and / or away from the bag's breathable openings.

[0142] In some examples, one or more handle members may be attached to or connected to one or more external straps 1340. In some examples, one or more handle members may be positioned along the length or width of the external straps. In some examples, the external straps may be configured to transmit the force exerted on the handle members along the length of the bag such that when the handle members are held or held together to pull, lift, carry or support at least a portion of the weight of the bag, the external straps may redistribute the weight of the bag along the external straps but not to the body of the bag or the opening of the bag.

[0143] In some examples, two or more external straps may be attached to the surface of the bag and arranged so that the ends of the straps are joined together to form a loop. In some examples, the loop may be configured as a handle for pulling, lifting, carrying, or supporting the weight of the bag. In some examples, the loop may be connected to the handle of the bag so that when the loop and handle are grasped together, a strong tensile force can be transmitted along the external strap to reduce or redistribute stress or strain on the handle or the part of the bag directly connected to the loop.

[0144] In some examples, one or more external straps 1340 may be configured to work not only with the body of the bag but also with the base of the bag and the cover assembly attached to the bag. In some examples, at least a portion of the external strap may be attached to or connected to a part of the bag that typically experiences stress or strain (e.g., the handle portion of the bag), and at least a portion of the external strap may be connected to the base of the bag or the cover assembly of the bag (e.g., by using rivets or other mechanical fasteners). In some examples, mechanically connecting the external strap to (i) the handle portion of the bag and / or (ii) the base of the bag or the cover assembly of the bag may allow the external strap to transmit or redistribute the tensile force acting on the bag handle to the base of the bag or the cover assembly of the bag, which may be stronger or more durable than the handle portion of the bag or other peripheral parts of the bag to which the bag handle is attached.

[0145] In some examples, the one or more external straps 1340 may be configured to work with one or more internal or external pockets of the bag. For example, in some examples, the edges of the pockets may be sewn to the internal or external surface of the main body section of the bag, and the external straps may cover or be positioned to cover the pockets and / or the sides or edges of the pockets. In such cases, the external straps may be configured to protect the sides or edges of the pockets and may provide an additional support layer for the pockets so that the pockets can be filled to capacity without compromising the structural integrity of the pockets.

[0146] fasteners In some embodiments, one or more fasteners 1345 may be attached to or connected to one or more external straps 1340. In some examples, one or more fasteners 1345 may include multiple mating fasteners (e.g., complementary male and female fasteners) that can be used to secure one or more external straps 1340 around the body of the bag 1000.

[0147] Connector Assembly In some embodiments, the bag may include a connector assembly that includes a fastener 1350. In some embodiments, the fastener 1350 may be provided along the back surface of the bag. In some embodiments, the fastener 1350 may be attached to one or more external straps 1340 that extend across the back surface of the bag.

[0148] In some examples, the fastener 1350 may be configured to engage with one or more other fasteners associated with one or more straps attached to or extending from one or more other bags, in order to detachably connect the travel bag to one or more other bags. In some examples, the fastener 1350 may be configured to engage with complementary fasteners provided along the back of the bag when the fastener 1350 is detached from one or more other bags, or with one or more other fasteners associated with one or more straps attached to or extending from one or more other bags. In other examples, the complementary fasteners may not be provided, or do not need to be provided, so that the fastener 1350 is always accessible and ready to engage with one or more other bags, or with one or more other fasteners associated with one or more straps attached to or extending from one or more other bags.

[0149] Bag coupling system In another aspect, the Disclosure provides various systems for detachably coupling multiple bags so that multiple bags can be easily and conveniently moved. In some examples, the bags disclosed herein may be detachably coupled to at least one other bag, as will be described in more detail below, to form a self-stabilizing or self-stabilizing bag assembly.

[0150] self-stabilizing In some embodiments, bags may be connected or linked to form a self-stabilizing or self-stabilized bag assembly so that the bag assembly can be easily moved or operated with minimal effort. As used in this disclosure, the terms “self-stabilizing” or “self-stabilized” may refer to a configuration in which the bags in a bag assembly are arranged such that the bags and / or the bag assembly exhibit one or more of the following stability characteristics: pitch, roll, and / or yaw. In some examples, the pitch, roll, and / or yaw stability of the bags and / or bag assembly can enhance the stability and maneuverability of the bags and / or bag assembly when the bags are connected or linked together to form a bag assembly.

[0151] In some examples, self-stabilizing bag assemblies may exhibit good internal and external pitch stability. Internal pitch stability may refer to the tendency of bags within a bag assembly to maintain the same tilt angle around a reference transverse axis when the bags are connected or joined to form a bag assembly. External pitch stability may refer to the tendency of bags within a bag assembly to sway forward or backward so that one or more wheels of the bag assembly are planted in the ground.

[0152] In some examples, self-stabilizing bag assemblies may exhibit good internal and external roll stability. Internal roll stability may refer to the tendency of bags within a bag assembly to maintain the same angular orientation around a reference longitudinal axis. External roll stability may refer to the tendency of a bag assembly to resist rotation around a reference longitudinal axis, such that one or more wheels of the bag assembly remain planted in the ground.

[0153] In some examples, self-stabilizing bag assemblies may exhibit good internal and external yaw stability. Internal yaw stability may refer to the tendency of bags within a bag assembly to maintain the same angular orientation or relative alignment along their respective vertical axes. External yaw stability may refer to the tendency of a bag assembly to resist rotation around its vertical axis, so that the bag assembly moves straight when rolled along or on the ground.

[0154] In some examples, when bags in a bag assembly are linked together and positioned in a self-stabilizing configuration, the weight of the bags may be distributed in a way that allows the bags in the bag assembly to remain in a fixed position and / or fixed orientation relative to each other. In some examples, the self-stabilizing configuration may distribute the weight of the bags across the wheels or rollers of the linked bags so that the bags in the self-stabilizing bag assembly remain in a state of mechanical equilibrium without requiring any other external support or input. In some examples, the bags in the self-stabilizing bag assembly may be positioned in a state of mechanical equilibrium so that the bags in the bag assembly do not move or shift and destabilize the balance or overall stability of the bag assembly. When bags are linked together to form a self-stabilizing bag assembly, the object can easily move the bag assembly with one hand without expending any further effort to position the assembly together and properly. Furthermore, whether stationary or moving, and whether tilted or not, the bag assembly can be fully self-stabilizing so that the bag assembly can be operated around or along an established route without any external support or input. In some examples, a bag assembly may remain self-stabilizing when the bag assembly is moving and / or when the bag assembly is stationary. In some examples, a bag assembly may remain self-stabilizing regardless of whether the bags within the bag assembly are positioned upright relative to each other, inclined, or on the ground surface below.

[0155] Luggage bag + 1 or more luggage bags Figure 14 schematically illustrates an example of a system for linking multiple bags together, which in turn allows the bags to be moved in series. In some examples, the multiple bags may include bags that can be checked in (for example, as shown in at least Figures 1A-1B, 2A-2C, 3A-3B, 4A-4B, and 5A-5B). In some examples, the multiple bags may include bags that can be carried on board as hand luggage (for example, as shown in at least Figures 6A-6B, 7A-7B, 8A-8B, and 9A-9B). In some examples, the multiple bags may include bags that can be used to carry or transport one or more items having an elongated shape factor (for example, as shown in at least Figures 10A-10B, 11A-11B, 12A-12B, and 13A-13C). In some examples, the plurality of bags may include at least one roller bag having two wheels mounted on a fixed axle. In some examples, the plurality of bags may include at least one spinner bag having four multidirectional spinner wheels that can swivel or rotate 360 ​​degrees.

In some examples, the first strap 1450 may have a first end connected to the first bag 1401 and a second end that can be detachably coupled to (i) the first bag 1401 and / or (ii) the second bag 1501. In some examples, if the object intends to transport the first bag 1401 alone, the second end of the first strap 1450 may be detachably coupled to the front of the first bag 1401. In some examples, when the object wishes to connect the first bag 1401 to the second bag 1501, the second end of the first strap 1450 may be detached from the front of the first bag 1401 and reattached to the top surface of the second bag 1501.

[0159] In some examples, the second end of the first strap 1450 may include a fastener for detachably connecting the second end of the first strap 1450 to (i) the first bag 1401 and / or (ii) the second bag 1501. In some examples, the fastener located on the second end of the first strap 1450 may be configured to engage with another fastener located on (i) the front of the first bag 1401 and / or (ii) the upper side of the second bag 1501. In some examples, the fastener located on the front of the first bag 1401 may be attached to the fastener located on the second end of the first strap 1450 when the first bag 1401 is in a standalone configuration (i.e., when the first bag 1401 is not connected to any other bag). In some examples, the fastener located on the front of the first bag 1401 may remain disconnected from any other fasteners when the first strap 1450 is used to connect the first bag 1401 and the second bag 1501. In some examples, a fastener located on the upper side of the second bag 1501 may be attached to a fastener located on the second end of the first strap 1450 when the first bag 1401 and the second bag 1501 are connected together using the first strap 1450. In some examples, the fastener located on the upper side of the second bag 1501 may not be connected to, or do not need to be connected to, any complementary fastener when the second bag 1501 is in a standalone configuration (i.e., when the second bag 1501 is not connected to any other bag).

[0160] In some examples, the second end of the first strap 1450 may be passed under the retractable handle associated with the second bag 1501 when connecting the first bag 1401 and the second bag 1501. In some examples, the first strap may be passed between a number of support members attached to the retractable handle in order to connect a fastener located on the second end of the first strap to a fastener located on the upper side of the second bag 1501. In some examples, when the first strap 1450 passes under the retractable handle and through a number of support members attached to the retractable handle of the second bag 1501, the retractable handle of the second bag 1501 may be configured to be accessible and / or deployable as needed even after the first bag 1401 and the second bag 1501 have been attached together using the first strap 1450. In some examples, the retractable handle may be configured to control or adjust the passage of the strap between the first and second bags so that (i) it holds the strap in one or more positions and / or (ii) it can be easily operated or moved when the first and second bags are attached together.

[0161] In some examples, the second end of the first strap 1450 may pass over the handle of the second bag 1501 when connecting the first bag 1401 and the second bag 1501. In some examples, if the first strap 1450 passes over the handle of the second bag 1501, the first strap may be configured to hold the handle of the second bag 1501 in a retracted position so that the handle of the second bag does not extend outward or upward when the first bag 1401 and the second bag 1501 are attached together using the first strap 1450.

[0162] Alignment As described above, in some embodiments, the first bag 1401 and the second bag 1501 may be attached together using a strap or joined together. Also, in some examples, the first bag 1401 and the second bag 1501 may be aligned with each other to maintain a stable nesting configuration that allows the first and second bags to be operated and / or transported together as a single unit.

[0163] In some examples, the front of the first bag 1401 may have a first contour or contour that corresponds to a second contour or contour of the cover assembly 1510 of the second bag 1501. In some examples, the front of the first bag 1401 may be shaped to engage with a projection or recess of the cover assembly 1510 of the second bag 1501 so that the first bag 1401 and the second bag 1501 can be nested together in a stable configuration that restricts or limits the movement of the first bag relative to the second bag, or vice versa.

[0164] strap length In some embodiments, the length of the strap connecting the first bag and the second bag may vary depending on the sizes of the first and second bags and their relative sizes, allowing the first and second bags to be positioned in a self-stabilizing configuration when connected using the strap. For example, in some preferred embodiments, the second bag may have a greater length, height, and / or width than the first bag, or the second bag may have a greater storage capacity than the first bag. In such cases, the strap extending from the first bag to the second bag may be of a first length so that the first and second bags can be positioned to form a self-stabilizing bag assembly when connected using the strap. In other embodiments, the second bag may have the same length, height, and / or width as the first bag, or the second bag may have the same storage capacity as the first bag. In such a case, the strap extending from the first bag to the second bag may have a second length that is longer than the first length, so that when the first and second bags are connected using the strap, they can be positioned and oriented to form a self-stabilizing bag assembly.

[0165] In some embodiments, the length of the strap connecting the first and second bags may be fixed. In other embodiments, the length of the strap connecting the first and second bags may be adjustable based on the size of the first or second bag and / or the relative size of the first and second bags, to ensure that the first and second bags can be positioned in a self-stabilizing configuration when connected together using the strap. In some examples, the strap length may be manually adjusted using one or more length adjustment mechanisms. The length adjustment mechanism may include a strap adjuster that includes, for example, a clip, slide, ring, hook, buckle, latch, or one or more fasteners (e.g., buttons or hook-and-loop fasteners such as Velcro®). In other examples, the strap may have an elastic portion or section that can stretch to allow adjustment of the strap length based on the amount of tension or tensile force applied to the strap. In some alternative embodiments, the strap may be connected to a spring-loaded reel mechanism that allows adjustment of the strap length by pulling the strap to a desired length or by releasing the strap, and the spring-loaded reel mechanism can return the strap to its initial or original length.

[0166] In some embodiments, the bag may include a separate extension strap which can be used to connect two or more bags of the same size, shape, or storage volume. In some examples, the separate extender strap may include a plurality of fasteners (e.g., male and female fasteners) configured to engage with (i) a connecting fastener associated with a first bag, and (ii) another connecting fastener associated with a second bag. In some examples, the plurality of fasteners may include a first fastener configured to engage with a first connecting fastener associated with a first bag and a second connecting fastener associated with a second bag. In some examples, the first connecting fastener may correspond to a connecting fastener located on the end of the strap that is attached to or connected to the first bag. In some examples, the second connecting fastener may correspond to a connecting fastener located on the top surface of the second bag. In some examples, the first connecting fastener associated with the first bag may be configured to be connected to a first end of the separate extender strap, and the second end of the separate extender strap may be connected to a second connecting fastener associated with the second bag to extend the length of the mechanical connection between the first bag and the second bag. In some examples, extending the mechanical connection between the first and second bags can facilitate the arrangement of the first and second bags in a self-stabilizing configuration, especially when the first and second bags are the same size, shape, or storage capacity.

[0167] Second and third bags In some embodiments, the traction response system may be configured to connect the second bag 1501 to the third bag 1601. In some examples, the third bag 1601 may be of the same type as the first bag and / or the second bag. In other examples, the third bag 1601 may be of a different type than the first bag and / or the second bag.

[0168] In some examples, the second and / or third bag may comprise one or more roller bags having two wheels mounted on a fixed axle. In some examples, the second and / or third bag may comprise one or more spinner bags having four multidirectional spinner wheels that can swivel or rotate 360 ​​degrees.

[0169] In some examples, the traction response system may include a second strap 1550 that extends between and connects a second bag 1501 and a third bag 1601. In some examples, the second strap 1550 may have a first end connected to the second bag 1501 and a second end that can be detachably coupled to (i) the second bag 1501 and / or (ii) the third bag 1601. In some examples, if the object intends to transport the second bag 1501 alone, the second end of the second strap 1550 may be detachably coupled to the front of the second bag 1501. In some examples, when the object wishes to connect the second bag 1501 to the third bag 1601, the second end of the second strap 1550 may be detached from the front of the second bag 1501 and reattached to the top surface of the third bag 1601.

[0170] In some examples, the second end of the second strap 1550 may include a fastener for detachably connecting the second end of the second strap 1550 to (i) the second bag 1501 and / or (ii) the third bag 1601. In some examples, the fastener located on the second end of the second strap 1550 may be configured to engage with another fastener located on (i) the front of the second bag 1501 and / or (ii) the upper side of the third bag 1601. In some examples, the fastener located on the front of the second bag 1501 may be attached to the fastener located on the second end of the second strap 1550 when the second bag 1501 is in a standalone configuration (i.e., when the second bag 1501 is not connected to any other bag). In some examples, the fastener located on the front of the second bag 1501 may remain disconnected from any other fastener when the second strap 1550 is used to connect the second bag 1501 and the third bag 1601. In some examples, the fastener located on the upper side of the third bag 1601 may be attached to a fastener located on the second end of the second strap 1550 when the second bag 1501 and the third bag 1601 are connected together using the second strap 1550. In some examples, the fastener located on the upper side of the third bag 1601 may not be, or do not need to be, attached to any other complementary fastener when the third bag 1601 is in a standalone configuration (i.e., when the third bag 1601 is not connected to any other bag).

[0171] In some examples, the second strap 1550 may be passed under the retractable handle associated with the third bag 1601 to connect the second bag 1501 and the third bag 1601 together. In some examples, the second strap may be passed between a plurality of support members attached to the retractable handle to connect a fastener located on the second end of the second strap to a fastener located on the upper side of the third bag 1601. In some examples, when the second strap 1550 is passed under the retractable handle and through the plurality of support members attached to the retractable handle of the third bag 1601, the retractable handle of the third bag 1601 may be configured to remain accessible and / or deployable as needed even after the second bag 1501 and the third bag 1601 have been attached together using the second strap 1550. In some examples, the retractable handle may be configured to (i) hold the strap in one or more positions and / or (ii) control or adjust the routing of the strap between the second and third bags so that the second and third bags can be easily operated or carried when attached together.

[0172] In some examples, the second end of the second strap 1550 may pass over the handle of the third bag 1601 when connecting the second bag 1501 and the third bag 1601. In some examples, if the second strap 1550 passes over the handle of the third bag 1601, the second strap may be configured to hold the handle of the third bag 1601 in a retracted position so that the handle of the third bag 1601 does not extend outward or upward when the second bag 1501 and the third bag 1601 are attached together using the second strap 1550.

[0173] Alignment As described above, in some embodiments, the second bag 1501 and the third bag 1601 may be attached together using straps or joined together. In some examples, the second bag 1501 and the third bag 1601 may also be aligned with respect to each other to maintain a stable nesting configuration that allows the second bag and the third bag to be operated and / or transported together as a single unit.

[0174] In some examples, the front of the second bag 1501 may have a contour or contour that corresponds to the contour of the cover assembly 1610 of the third bag 1601. In some examples, the front of the second bag 1501 may be shaped to engage with a projection or recess of the cover assembly 1610 of the third bag 1601 so that the second bag 1501 and the third bag 1601 can be nested together in a stable configuration that restricts or limits the movement of the second bag relative to the third bag, or vice versa.

[0175] strap length In some embodiments, the length of the strap connecting the second and third bags may vary depending on the size of the second or third bag, and / or the relative sizes of the second and third bags, to allow the second and third bags to be positioned in a self-stabilizing configuration when they are connected using the strap. For example, in some preferred embodiments, the third bag may be configured to have a greater length, height, and / or width than the second bag, or the third bag may have a greater storage capacity than the second bag. In such cases, the strap extending from the second bag to the third bag may be of a first length so as to allow the second and third bags to be positioned to form a self-stabilizing bag assembly when they are connected using the strap. In other embodiments, the third bag may have the same length, height, and / or width as the second bag, or the third bag may have the same storage capacity as the second bag. In such cases, the strap extending from the second bag to the third bag may be a second length longer than the first length, so that when the second and third bags are connected using the strap, they can be positioned and oriented to form a self-stabilizing bag assembly.

[0176] In some embodiments, the length of the strap connecting the second and third bags may be fixed. In other embodiments, the length of the strap connecting the second and third bags may be adjustable based on the size of the second or third bag and / or the relative size of the second and third bags, to ensure that the second and third bags can be positioned in a self-stabilizing configuration when connected together using the strap. In some examples, the strap length may be adjusted manually using one or more length adjustment mechanisms. The length adjustment mechanism may include a strap adjuster that includes, for example, a clip, slide, ring, hook, buckle, latch, or one or more fasteners (e.g., buttons or hook-and-loop fasteners such as Velcro®). In other examples, the strap may have an elastic portion or section that can stretch to allow adjustment of the strap length based on the amount of tension or tensile force applied to the strap. In some alternative embodiments, the strap may be coupled to a spring-loaded reel mechanism that allows adjustment of the strap length by pulling the strap to a desired length or by releasing the strap, so that the spring-loaded reel mechanism can return the strap to its initial or original length.

[0177] In some embodiments, the bag may include a separate extension strap which can be used to connect two or more bags of the same size, shape, or storage volume. In some examples, the separate extender strap may include a plurality of fasteners (e.g., male and female fasteners) configured to engage with (i) a connecting fastener associated with a second bag, and (ii) another connecting fastener associated with a third bag. In some examples, the plurality of fasteners may include a first fastener configured to engage with the connecting fastener associated with the second bag, and another connecting fastener associated with the third bag. In some examples, the connecting fastener associated with the second bag may correspond to a connecting fastener located on the end of the strap attached to or connected to the second bag. In some examples, the connecting fastener associated with the third bag may correspond to a connecting fastener located on the top surface of the third bag. In some examples, the connecting fastener associated with the second bag may be connected to a first end of the separate extender strap, and the second end of the separate extender strap may be connected to another connecting fastener associated with the third bag to extend the length of the mechanical connection between the second bag and the third bag. In some examples, extending the mechanical connection between the second and third bags can facilitate the arrangement of the second and third bags in a self-stabilizing configuration, especially when the second and third bags are the same size, shape, or storage volume.

[0178] Luggage bag + travel bag Figures 15A and 15B schematically illustrate other non-limiting examples of a system for linking multiple bags together so that the multiple bags can be moved in tandem. In some examples, the multiple bags may include bags that can be checked in (e.g., as shown in at least Figures 1A-1B, 2A-2C, 3A-3B, 4A-4B, and 5A-5B). In some examples, the multiple bags may include bags that can be carried onto a vehicle as hand luggage (e.g., as shown in at least Figures 6A-6B, 7A-7B, 8A-8B, and 9A-9B). In some examples, the multiple bags may include bags that can be used to carry or transport one or more items having an elongated shape factor (e.g., as shown in at least Figures 10A-10B, 11A-11B, 12A-12B, and 13A-13C). In some examples, the multiple bags may include at least one roller bag having two wheels mounted on a fixed axle. In some examples, the multiple bags may include at least one spinner bag having four multidirectional spinner wheels that can swivel or rotate 360 ​​degrees.

[0179] In some embodiments, the traction response system may be configured to connect the first bag 1701 to the second bag 1801. In some examples, the first bag may include carrying a luggage bag or a checked baggage bag. In some examples, the first bag may comprise a roller bag having two wheels mounted on a fixed axle. In some examples, the first bag may comprise a spinner bag having four multi-directional spinner wheels. In some examples, the second bag may comprise an elongated travel bag having a different size and / or shape from the first bag.

[0180] In some examples, the traction response system may include a first strap 1750 that extends between and connects a first bag 1701 and a second bag 1801. In some examples, the first strap 1750 may have a first end connected to the first bag 1701 and a second end that can be detachably coupled to (i) the first bag 1701 and / or (ii) the second bag 1801. In some examples, if the object intends to transport the first bag 1701 alone, the second end of the first strap 1750 may be detachably coupled to the front of the first bag 1701. In some examples, when the object wishes to connect the first bag 1701 to the second bag 1801, the second end of the first strap 1750 may be configured to be detached from the front of the first bag 1701 and reattached to the second bag 1801.

[0181] In some examples, the second end of the first strap 1750 may include a fastener for detachably connecting the second end of the first strap 1750 to (i) the first bag 1701 and / or (ii) the second bag 1801. In some examples, the fastener located on the second end of the first strap 1750 may be configured to engage with a complementary fastener located on the front of the first bag 1701. In some examples, the fastener located on the second end of the first strap 1750 may be configured to engage with another fastener provided on the second bag 1801.

[0182] In some examples, the fasteners provided on the second bag 1801 may be positioned along the back of the second bag 1801 (i.e., the side of the second bag 1801 facing the first bag 1701). In some examples, the fasteners provided on the second bag 1801 may be positioned along an external strap extending across or around the second bag 1801. In some examples, the fasteners provided on the second bag 1801 may be positioned directly above and / or near the upper edge of the cover piece 1810 of the second bag 1801. In some examples, the fasteners provided on the second bag 1801 may be positioned within a predetermined distance from the upper edge of the cover piece 1810 of the second bag 1801. In some examples, the given distance may be up to approximately 200 millimeters (mm), 190 mm, 180 mm, 170 mm, 160 mm, 150 mm, 140 mm, 130 mm, 120 mm, 110 mm, 100 mm, 90 mm, 80 mm, 70 mm, 60 mm, 50 mm, 40 mm, 30 mm, 20 mm, 10 mm, or less.

[0183] In some examples, a complementary fastener located on the front of the first bag 1701 may be attached to a fastener located on the second end of the first strap 1750 when the first bag 1701 is in a standalone configuration (i.e., when the first bag 1701 is not connected to any other bag). In some examples, the complementary fastener located on the front of the first bag 1701 may remain disconnected from any other fastener when the first strap 1750 is used to connect the first bag 1701 and the second bag 1801.

[0184] In some examples, the fasteners positioned on the second bag 1801 may be configured to attach to a fastener positioned on the second end of the first strap 1750 when the first bag 1701 and the second bag 1801 are connected together using the first strap 1750. In some examples, the fasteners positioned on the second bag 1801 may be detached from or unconnected to the fastener positioned on the second end of the first strap 1750 when the subject wishes to transport or operate the second bag 1801 in a standalone configuration (i.e., when the second bag 1801 is not connected to any other bag). In some examples, the fasteners positioned on the second bag 1801 may be connected to a complementary fastener provided along the back of the second bag when the second bag 1801 is in a standalone configuration. In other examples, the fasteners positioned on the second bag 1801 may not be, or do not need to be, connected to any other complementary fastener when the second bag 1801 is in a standalone configuration.

[0185] Alignment In some embodiments, the first bag 1701 and the second bag 1801 may be attached or joined together using straps. In some examples, when the first bag 1701 and the second bag 1801 are attached together, the first and second bags may be configured to align naturally with each other to maintain a stable nested configuration that allows the first and second bags to be operated and / or transported together as a single unit.

[0186] In some examples, the front of the first bag 1701 may have a first contour or contour that corresponds to a second contour or contour of the cover piece 1810 of the second bag 1801. In some examples, the front of the first bag 1701 may be shaped to engage with a projection or recess of the cover piece 1810 of the second bag 1801, and vice versa, so that the first bag 1701 and the second bag 1801 are nested together in a stable configuration that restricts or limits the movement of the first bag relative to the second bag.

[0187] Movement of the bag assembly In some embodiments, multiple bags may be linked or connected together to form a self-stabilizing bag assembly. The multiple bags may include any of the bags described herein.

[0188] In some examples, when multiple bags are linked or connected together to form a self-stabilizing bag assembly, a portion of the weight of the bag assembly may rest on the wheels of the first bag (i.e., the lead bag located in front of the bag assembly closest to the subject). In some examples, the remaining weight of the bag assembly may rest on the wheels of other bags within the bag assembly (e.g., bags located behind or following the first bag).

[0189] In some examples, when the object wishes to move the bag assembly, the object may tilt one or more bags in the bag assembly forward. In some examples, the bag behind the first bag may tilt forward toward the first bag as the first bag tilts. In some examples, when the bag behind the first bag is tilted forward toward the first bag, at least a portion of the weight of the trailing bag may be shifted forward (e.g., on and / or in front of the wheels of the first bag) so that the bag assembly can balance on one or more wheels of the first bag. In some examples, when the bag behind the first bag is tilted forward toward the first bag, the back of the first trailing bag may be pressed against the front of the first lead bag so that the bag assembly can maintain a self-stabilizing configuration that improves the stability and maneuverability of the bag assembly. In some examples, when the first bag is tilted forward and the trailing bag tilts forward toward the first bag, one or more wheels of the trailing bag may still be in contact with the ground below so that at least a portion of the weight of the bag assembly can be placed on the wheels of the trailing bag. In some examples, when the first bag is tilted forward and the trailing bag tilts forward toward the first bag, one or more wheels of the trailing bag may be lifted off the ground so that the weight of the bag assembly is shifted primarily to the wheels of the first lead bag.

[0190] In some examples, when a self-stabilizing bag assembly is repositioned to a target position, the bag assembly may move or tilt back toward a neutral or upright position. In some examples, when the self-stabilizing bag assembly returns to a neutral or upright position, the center of gravity of the bag assembly may be shifted backward, and the weight of the bag assembly may be redistributed across the wheels of the bags within the bag assembly, so that the self-stabilizing bag assembly can remain upright and stationary without any external support or input.

[0191] Spinner bag In some examples, the bag assembly may include one or more spinner bags, as described elsewhere in this disclosure. In some examples, the bag assembly may be moved or transported while one or more spinner bags are in an upright position. In some examples, the object may be configured such that it is not necessary to tilt one or more spinner bags to move or transport the bag assembly. In other examples, the object moves the bag assembly while one or more spinner bags are in an inclined position.

[0192] Reading Spinner Bag In some examples, one or more spinner bags may be configured as lead bags (i.e., first bags) within the bag assembly. In some examples, the lead bags may be configured to remain upright while the bag assembly is moving or stationary. In some examples, the wheels of the lead bags may remain in contact with the ground surface below while the bag assembly is moving or stationary. In some examples, the lead bags may be tilted forward so that one or more wheels of the lead bags are lifted off the ground. In some examples, one or more other wheels of the lead bags may remain in contact with the ground surface below so that one or more other wheels of the lead bags can bear at least a portion of the weight of the bag assembly.

[0193] In some examples, one or more bags following the first bag may include a spinner bag. In some examples, the bag assembly may be operated or transported while the spinner bag is in an upright position. In some examples, the spinner bag may remain in an upright position without impairing the stability and / or operability of the bag assembly. In some examples, the spinner bag may be tilted, and the bag assembly may be operated or transported while the spinner bag is in a tilted position.

[0194] In some examples, one or more bags following the first bag may comprise roller bags. In some examples, the bag assembly may be operated or transported while the roller bag is in an inclined position. In some examples, when the roller bag is in an inclined position, the roller bag may be configured to tilt forward toward the first bag while the first bag remains upright. In some examples, when the roller bag tilts forward toward the first bag, the back surface of the roller bag may contact the front surface of the first lead bag, and the weight of one or more trailing bags may be shifted forward toward the first bag so that at least a portion of the weight of the bag assembly can be balanced on one or more wheels of the first bag in order to form a self-stabilizing bag assembly as described elsewhere in this disclosure. In some examples, when the rolling bag tilts forward toward the first bag, one or more wheels of the rolling bag may still be in contact with the ground surface below so that at least a portion of the weight of the bag assembly can be placed on the wheels of the rolling bag.

[0195] In some examples, one or more bags following a first bag may include a first trailing bag and one or more other bags configured to follow the first trailing bag. In some examples, the one or more other bags may include a spinner bag. In some examples, the spinner bag may include a luggage bag or travel bag that can be transported in an upright and / or inclined position. In some examples, one or more other bags may comprise a roller bag. In some examples, the roller bag may include a luggage bag or travel bag that can be transported in an inclined position.

[0196] Trailing spinner bag In some examples, one or more spinner bags may be configured as trailing bags within a bag assembly. In some examples, the trailing bags may be configured to follow the first (lead) bag of the bag assembly. In some examples, the first (lead) bag may comprise a spinner bag that can be transported while in an upright position. In other examples, the first (lead) bag may comprise a roller bag that can be transported while in an inclined position.

[0197] In some examples, the trailing bag may be upright while the bag assembly is moving and / or while the bag assembly is stationary. In some examples, the trailing bag may remain upright regardless of whether the first (lead) bag is upright or inclined. In some examples, the trailing bag may be configured to maintain the self-stabilizing properties of the bag assembly while upright and without needing to be tilted relative to the first (lead) bag. In some examples, the wheels of the trailing bag may be configured to contact the ground surface below while the bag assembly is moving or stationary. In some examples, the wheels of the trailing bag may be in contact with the ground surface below so that the wheels of the trailing bag can bear at least a portion of the weight of the bag assembly.

[0198] In some examples, the trailing bag may be in an inclined position while the bag assembly is moving and / or while the bag assembly is stationary. In some examples, the trailing bag may remain in an inclined position regardless of whether the first (lead) bag is upright or inclined.
