Description
- This application relates generally to an apparatus for transporting luggage and, more specifically, to an apparatus for temporarily coupling a plurality of luggage pieces together to simplify transportation of the combined luggage pieces together as a collective unit.
- Travelers have traditionally been required to carry luggage pieces such as carry-on suitcases through airports and other locations while en route to a destination. More recently, such luggage pieces have been provided with wheels to allow travelers to pull such luggage pieces, thereby reducing the physical demands of transporting luggage while traveling.
- Although pulling a rolling suitcase is much less demanding of travelers than carrying a suitcase, traveling with more than a single such rolling suitcase requires each suitcase to be pulled separately. This can be a daunting task for a traveler who has packed more than one suitcase for an extended stay at a destination, or when traveling in the company of children who may not be able to pull their own luggage. Such travelers will be required to pull each individual rolling suitcase separately, making it difficult for the travelers to carry anything else such as a coat, airline tickets, or small children.
- Accordingly, there is a need in the art for a luggage system that allows a plurality of luggage pieces to be coupled together and collectively transported together as a unit.
- According to one aspect, the subject application involves a luggage piece that can be coupled to a second luggage piece to be transported with the second luggage piece as a joined unit. The second luggage piece includes a plurality of adjustable rollers having a variable rolling direction, where the luggage piece includes a housing defining an interior compartment that stores items to be transported within the luggage piece. A retractable handle is provided to the housing, and is adjustable between a recessed position where a handgrip provided to the handle is disposed proximate to the housing and a deployed position where the handgrip is extended distally away from the housing. A plurality of rollers are coupled to the housing on which the luggage piece is to be rolled. A coupling system includes a plurality of tethers that cooperate with one or more receivers provided to the second luggage piece to couple the second luggage piece to the luggage piece at a position that allows the joined unit to roll on the in-line rollers and the adjustable rollers. The adjustable rollers provided to the second luggage piece afford the joined unit a steering capability.
- According to another aspect, the subject application involves a luggage system that includes a first luggage piece and a second luggage piece. The first luggage piece includes a housing defining an interior compartment that stores items to be transported within the first luggage piece. A retractable handle is adjustable between a recessed position where a handgrip provided to the handle is disposed proximate to the housing and a deployed position where the handgrip is extended distally away from the housing. Two or more rollers are coupled to the housing on which the luggage piece is to be rolled. The second luggage piece includes a housing defining an interior compartment that stores items to be transported within the second luggage piece, and a retractable handle that is adjustable between a recessed position where a handgrip provided to the handle is disposed proximate to the housing and a deployed position where the handgrip is extended distally away from the housing. A plurality of rollers are coupled to the housing on which the second luggage piece is to be rolled, including at least two adjustable rollers having a variable rolling direction. A coupling system including a plurality of tethers couples the first and second luggage pieces together to be rolled on the at least two in-line rollers and the at least two adjustable rollers together as a joined unit. The joined unit is steerable through adjustment of the variable rolling direction of the adjustable rollers.
- According to another aspect, the subject application involves a luggage system that includes a first luggage piece and a second luggage piece that can be coupled together to form a joined unit. The first luggage piece includes a housing defining an interior compartment for storing items to be transported within the first luggage piece, and a retractable handle.

bag 18 can optionally be established by one or more regulation(s) promulgated by a governing body or trade association of the commercial airline industry such the U.S. Federal Aviation Administration. Although theluggage pieces unit 22 are described herein as being carry-onbags 18, the present invention is not so limited. Instead, eachluggage piece bag 18, a suitcase having dimensions greater than those allowable for carry-onbags 18, or a combination thereof. However, for the sake of brevity, theluggage system 10 will be described herein as comprising at least two, and optionally threeluggage pieces bags 18, as shown inFIG. 5 . - As shown in
FIG. 2 , the carry-onbag 18 includes ahousing 20 defining an interior compartment for storing items to be transported within the carry-onbag 18. Thehousing 20 can include a substantially rigid shell formed from plastic sides arranged in a generally-cubicle formation, although each side does not necessarily have the same identical dimension. As an illustrative example, the carry-onbag 18 can include the dimensions of about: twenty two inches (22 in.) in length (L), fourteen inches (14 in.) in width (W), and ten inches (10 in.) in height (H) (i.e., 22 in.×14 in.×10 in.), but other dimensions are within the scope of the present disclosure. Further, each carry-onbag 18 included as one of theluggage pieces bag 18. - The externally-exposed surfaces of the
housing 20, or at least portions thereof, can includeconnection regions 24 that can cooperate with a tether 26 (FIG. 1 ) as described in detail below to couple at least two, and optionally three ormore luggage pieces unit 22. For example, the externally-exposed surfaces can include a patch of material forming a first portion of a hook-and-loop fastening system commonly referred to by the trademark Velcro®, for example, as the connection region 24 (FIG. 2 ). The compatible, mating portion of the hook-and-loop fastening system can be supported adjacent to a distal end 28 (FIG. 1 ) of thetether 26 that extends away from thehousing 20. According to alternate embodiments, theconnection region 24 can include a portion of a buckle, snap, or any other releasable mechanical fastener that can be engaged by a portion of thetether 26 to establish a friction-fit connection that couples the distal end. Although theconnection region 24 is shown inFIG. 2 as a well-defined portion that encompasses less than a significant portion of thehousing 20, it is to be understood that theconnection region 24 can optionally include any portion of the housing's surface area. For instance, ahousing 20 having a fabric exterior surface can receive the mating portion of the hook-and-loop fastener at approximately any location on the exposed fabric. Thus, theconnection region 24 can include an isolated region of thehousing 20, or anywhere on thehousing 20 where a suitable and compatible fastening component is available. - According to alternate embodiments, a system comprising a magnetic and/or a magnetically-attractive material can be provided as the
connection region 24 and the compatible, mating portion provided adjacent to thedistal end 28 of thetether 26. Magnetic attraction between the magnet and magnetically-attractive portion serves to releasably couple thedistal end 28 of thetether 26 to theconnection region 24, and thereby couple immediately adjacent luggage pieces together as described below. Regardless of the particular materials used, the fastening system provided to theconnection region 24 and thedistal end 28 of the tether(s) 26 releasably couples thedistal end 28 of thetether 26 extending from one carry-onbag 18 to an immediately-adjacent carry-onbag 18. As a releasable coupling, thedistal end 28 of thetether 26 can repeatedly be connected, by hand, and subsequently removed to/from itscorresponding connection region 24 provided to the immediately adjacent (e.g., not separated from each other by an intervening carry-on bag 18) carry-onbag 18 without damaging thetether 16, theconnection region 24 or the carry-onbag 18 to an extent that renders any such components unfit for subsequent usage. - The one
tether 26, or plurality oftethers 26 can optionally include apermanent tether 26 that is affixed to at least one, and optionally each of the carry-onbags 18 included in theluggage system 10, in a non-releasable manner. Thepermanent tether 26 prevents removal of thetether 26 without damaging thepermanent tether 26 itself, or the carry-onbag 18 to which it is affixed. For example, one or more of thetethers 26 can be stitched using nylon thread or othersuitable stitching 27 to a first luggage piece 12 (FIG. 1 ), for example. According to alternate embodiments, a proximate end of thepermanent tether 26 can be adhesively coupled to thehousing 20 of thefirst luggage piece 12, or secured to be spooled about a spool provided to thefirst luggage piece 20, for example. When not coupling luggage pieces together, thedistal end 28 of thetether 26 can optionally cooperate with a portion of thehousing 20, or can otherwise be supported or stowed on the housing of the luggage piece to which thetether 26 is affixed in a manner that does not interfere with use of that luggage piece by itself, separate from the other luggage pieces. - Additionally, the
tethers 26 are described herein as being straps of a flexible material such as nylon or the like. However, it is to be understood that any suitable fastener (e.g., plastic, metal or other rigid braces; elastic bands; etc. . . . ) that can extend between theluggage pieces - To promote and optionally maintain proper alignment and/or arrangement of the
luggage pieces unit 22, one or more of the externally-exposed surfaces of thehousing 20 of eachluggage piece luggage piece 12 shown inFIG. 8 , the externally-exposed surface of thehousing 20 that is to be placed in close proximity to an opposing surface of the immediatelyadjacent luggage piece 14 is provided with a plurality ofmale alignment structures 60. Eachmale alignment structure 60 protrudes from a substantially planarfront side 48 of thehousing 20. For the embodiment shown inFIG. 8 , fourmale alignment structures 60 each having a generally-rectangular footprint on thefront side 48 are arranged at corner regions of thefront side 48. An elongatedmale alignment structure 60 extends in a vertical direction while theluggage piece 12 is standing upright, in a central region of thefront side 48, along a longitudinal axis of thefront side 48. The various sides of thehousing 20 can be formed from a substantially-rigid plastic to maintain a fixed arrangement and orientation of themale alignment structures 60 while theluggage piece 12 is closed. According to alternate embodiments, however, themale alignment structures 60 can have a footprint on thefront side 48 of any desired shape. At least one, and optionally a plurality of themale alignment structures 60 can optionally protrude from an externally-exposedsurface 62 of thetether 26 that can be pivoted outwardly, generally away from thefront side 48 to couple the luggage piece to anadjacent luggage piece 14, as shown inFIGS. 6 and 7 . According to alternate embodiments, themale alignment structures 60 protruding from the externally-exposedsurface 62 of thetether 26 can be hollow caps, covering the actualmale alignment structures 60 protruding from thefront side 48. While such atether 26 is not in use to couple luggage pieces together, but is in a stowed state coupled to thefront side 48 of its own luggage piece, the hollow cap may be folded over the underlyingmale alignment structure 60, which are received within the hollow space defined by the hollow cap. When thetether 26 is deployed to couple luggage pieces together, the once-hiddenalignment structure 60 is exposed to cooperate with the respectivefemale alignment structure 66 of the coupled luggage piece. - A
proximate side 46 of thehousing 20 adjacent to a vertical plane in which thehandle 30 extends and retracts as described in detail below can be provided with at least one, and optionally a plurality offemale alignment structures 66, as shown inFIGS. 7 and 9 . Eachfemale alignment structure 66 can be a recess formed in theproximate side 46 of thehousing 20, and have a location and shape with a footprint on theproximate side 46 of thehousing 20 that is compatible to receive themale alignment structures 60. For the example illustrated in the drawings, fourfemale alignment structures 66 each having a generally-rectangular footprint on theproximate side 46 are arranged at corner regions of theproximate side 46. An elongatedfemale alignment structure 66 extends in a vertical direction while theluggage piece 12 is standing upright, in a central region of theproximate side 46, along a longitudinal axis of theproximate side 46. Although the alignment structures are described herein as being amale alignment structure 60 on thefront side 48 and afemale alignment structure 66 on theproximate side 46, the present disclosure is not so limited.Male alignment structures 60 can be provided to theproximate side 46 andfemale alignment structures 66 can be provided to thefront side 48, or male andfemale alignment structures female alignment structures luggage pieces male alignment structures 60 are described herein as being provided to thefront face 48 and thefemale alignment structures 66 are described herein as being provided to theproximate side 46 for illustrative purposes. - One, or a plurality of the
male alignment structures 60 can optionally be provided with an embeddedmagnet 72, a first portion of a hook-and-loop fastener, or any other suitable connecting structure, shown using hidden lines inFIG. 8 . For embodiments that include a magnet, themagnet 72 can be embedded within the male alignment structure(s) 60 to be concealed from view when those male alignment structure(s) 60 are observed from outside of thehousing 20. For example, eachmagnet 72 can be embedded within, or coupled to an inward-facing surface of the material forming the male alignment structure(s) 60. For embodiments including the first portion of a hook and loop fastener, the first portion can be coupled to an external surface of the male alignment structure(s) 60, and visible when thefront side 48 of theluggage piece 12 is observed. Because themale alignment structure 60 protrudes outwardly, from thefront side 48, a shield can optionally be provided as part of, or adjacent to themale alignment structure 60. For example, as shown inFIG. 12 , the extended, distal end of themale alignment structure 60 can include thefirst portion 65 of the hook-and-loop fastener. Thisportion 65 of the hook-and-loop fastener can be recessed relative to a surroundingshield 61. Thus, if the luggage piece is laid front side down, theportion 65 of the hook-and-loop fastener will be supported above the ground or other supporting surface, and thereby protected from contact. The correspondingfemale alignment structure 66 can include the second portion of the hook-and-loop fastener protruding outward from a surrounding recess. Theshield 61 can be received within the recess, and the first and second portions of the hook-and-loop fastener can be placed in contact with each other. - One, or a plurality of the female alignment structure(s) 66 can optionally be provided with an embedded magnetically-
attractive material 76, a second portion of a hook-and-loop fastener that is compatible with the first portion, or any other structure compatible with a different connecting structure provided to the respectivemale alignment structure 60, shown using hidden lines inFIG. 9 . The magnetically-attractive material 76 can optionally be provided to only a subset (e.g., fewer than all) of thefemale alignment structures 66 that correspond tomale alignment structures 60 provided with amagnet 72, or can optionally be provided to all of thefemale alignment structures 66 just as themagnet 72 can optionally be provided to a subset, or all of themale alignment structures 62. Like eachmagnet 72, the magnetically-attractive material 76 can optionally be embedded within the female alignment structure(s) 66 to be concealed from view when those female alignment structure(s) 66 are observed from outside of thehousing 20. For example, each magnetically-attractive material 76 can be embedded within, or coupled to an inward-facing surface of the material forming the female alignment structure(s) 66. For embodiments including the second portion of the hook-and-loop fastener, the second portion can be coupled to an external surface of the female alignment structure(s) 66, and visible when theproximate side 46 of theluggage piece 12 is observed. For embodiments including a magnetic, hook-and-loop fastener or other joining system provided to the alignment structures, thetethers 26 of the coupling system to couple the luggage pieces together can be used in combination with the magnetic, hook-and-loop fastener or other joining system. For other embodiments, the magnetic, hook-and-loop fastener or other joining system can be used instead of thetethers 26 to couple theluggage pieces - When the
luggage piece 12 is brought into contact with anotherluggage piece 14 to form a joinedunit 22, themale alignment structures 60 of theluggage piece 12 are at least partially received within thefemale alignment structures 66 of theother luggage piece 14 to establish a linear arrangement of theluggage pieces unit 22. For embodiments including one or more of the magnet(s) 72 and the magnetically-attractive material(s) 76, the magnetic force there between urges theluggage pieces luggage pieces tether 26 and theconnection region 24 provided to theluggage piece 14. The cooperation between thefemale alignment structures 66 and their respectivemale alignment structures 60 helps to limit lateral displacement of one luggage piece (e.g., luggage piece 12) relative the contiguously-positioned luggage piece (e.g., luggage piece 14) once they are coupled together. - Although the
luggage piece 12 is described individually inFIGS. 8 and 9 as having both themale alignment structures 60 and thefemale alignment structures 66, it is to be understood that theluggage piece 12 can optionally have only one of the male orfemale alignment structures luggage piece 12 includes only thefemale alignment structures 66, then it can form part of a joinedunit 22 by being arranged to position theproximate side 46 of theluggage piece 12 in opposition to afront side 48 of anotherluggage piece 14, for example, including themale alignment structures 60. Similarly, if theluggage piece 12 includes only themale alignment structures 60, then it can form part of a joinedunit 22 by being arranged to position thefront side 48 of theluggage piece 12 in opposition to aproximate side 46 of anotherluggage piece 14, for example, including thefemale alignment structures 66. If theluggage piece 12 includes both themale alignment structures 60 and thefemale alignment structures 66, then it can form part of a joinedunit 22 by being arranged to position theproximate side 46 of theluggage piece 12 in opposition to afront side 48 of anotherluggage piece 14, for example, that includes themale alignment structures 60, and/or to position thefront side 48 of theluggage piece 12 in opposition to aproximate side 46 of anotherluggage piece 16, for example, that includes thefemale alignment structures 66. - Further, although the
luggage piece 12 is described in detail inFIGS. 8 and 9 , one or moreadditional luggage pieces luggage piece 12. In other words, each of theluggage pieces male alignment structures 60 on thefront side 48, only one or more of thefemale alignment structures 66, or one or more of themale alignment structures 60 and one or more of thefemale alignment structures 66. Thus, theluggage pieces units 22 of any desired size. Additionally, thefront side 48 of thehousing 20 is described as including one or moremale alignment structures 60 while theproximate side 46 is described as including one or morefemale alignment structures 66. However, thefront side 48 andproximate side 46 can each independently be configured to include one or more of themale alignment structures 60, one or more of thefemale alignment structures 66, or a combination of one or moremale alignment structures 60 and one or morefemale alignment structures 66. Similarly, theoptional magnet 72 is described as being provided to the male alignment structure(s) 60 while the optional magnetically-attractive material 76 is described as being provided to the male alignment structure(s) 66. However, themagnet 72 and the magnetically-attractive material 76 can optionally be provided to the male alignment structure(s) 60, the female alignment structure(s) 66, or to the male alignment structure(s) 60 and the female alignment structure(s) 66 such that an alignment structure provided with themagnet 72 is arranged to be opposed to an alignment structure provided with the magnetically-attractive material 76 when luggage pieces are coupled together in a joinedunit 22. Further, one or more of theluggage pieces front side 48 only, and lack any alignment features on theproximate side 46. Thus, when forming a rearward-most luggage piece of a joinedunit 22, the rear end of the joinedunit 22 has an aesthetically-pleasing appearance. Similarly, a front end unit can include one or more male and/or female alignment features on theproximate side 46 only, and lack any alignment features on thefront side 48. Thus, when forming a forward-most luggage piece of a joinedunit 22, the front end of the joinedunit 22 has an aesthetically-pleasing appearance. - The
alignment structures luggage pieces FIG. 10 , for example, the male alignment features 60 provided to thefront side 48 of themid-sized luggage piece 14 are aligned to cooperate with the female alignment features 66 provided to theproximate side 46 of the carry-onluggage piece 12, while bothluggage pieces adjustable rollers 42. Optionally, fewer than all of the male alignment features 60 of themid-sized luggage piece 14 may cooperate with corresponding female alignment features 66 of the carry-onluggage piece 12. For example, at least a portion of, and optionally an entirety of the upper-most male alignment features 60A arranged on theluggage piece 14 at a vertical elevation above the shorter carry-onluggage piece 12 can optionally remain exposed above the carry-onluggage piece 12. For the embodiments shown inFIGS. 10 and 11 , the exposed portions of the male alignment features 60A do not cooperate with any portion of the carry-onluggage piece 12 10. However, a bottom region of the male alignment features 60A can optionally cooperate with partial female alignment features 66 provided to the carry-onluggage piece 12. In this manner, the arrangement of alignment features 60, 66 provided to theluggage pieces luggage pieces - Each carry-on

According to alternate embodiments, thefirst luggage piece 12 can optionally include the telescopically-retractableU-shaped handle 30, while anotherluggage piece 16, for example, includes a retractable belt handle 54 (FIG. 1 ), or a handle including a single, telescopically adjustable arm with the handgrip supported thereon. The belt handle 54 includes a belt of nylon or other suitable material that is stored about a spool coupled to thehousing 20, and ahandgrip 32 provided to a distal end of the retractable belt. The spool can optionally be recessed within a portion of thehousing 20 to be concealed from view when thehousing 20 is observed. Like the U-shaped embodiment of thehandle 32, the retractable belt is adjustable relative to thehousing 20 between a recessed position where thehandgrip 32 is disposed proximate to thehousing 20 and a deployed position where thehandgrip 32 is extended distally away from thehousing 20. To assist users in transporting the joinedunit 22, a leash 55 (FIG. 11 ) can optionally be removably coupled to a receiver 59 (FIG. 9 ) that is located adjacent to abottom surface 44 of thehousing 20. The leash can be formed from a strap of flexible material such as nylon, for example, having a handle orloop 56 at one end to be grasped by the user. The receiver can be a hook, post, or other suitable structure to which thelease 55 can be removably coupled. According to one embodiment, being considered adjacent to thebottom surface 44 positions thereceiver 59 at an elevation within the lowermost two-thirds, or the lowermost one half, or the lowermost one third of theproximate side 46 in the view ofFIG. 9 . The lower elevation of the connection of theleash 55 to the luggage piece allows at least some of the pulling force to be in the upward direction, taking a portion of the force that would otherwise be imparted on the forward rollers and distributing that force over all of the rollers. The receiver being at such an elevation helps to avoid tipping the luggage piece over while it is being pulled. Although thereceiver 59 is at such an elevation, thereceiver 59 can be provided at a location along theproximate side 46, at a location along one or bothlateral sides 57, or any other suitable location. A clasp or other adjustable connector provided to theleash 55 can cooperate with thereceiver 59 to releasably couple theleash 55 to the luggage piece. - The carry-on

As shown inFIG. 2 , the plurality ofrollers line rollers 40 arranged along aproximate side 46 of thehousing 20 adjacent to the vertical plane in which thehandle 30 extends and retracts. Each of the in-line rollers 40 can include a wheel that rotates about an axle having a fixed rolling direction, which does not pivot or otherwise change in response to a change of direction in which the carry-onbag 18 is rolling while being pulled with thehandle 30. - The plurality of
rollers bag 18 inFIG. 2 also include at least two, and optionally more,adjustable rollers 42. Theadjustable rollers 42 also extend downwardly beyond thebottom surface 44 of the housing, but are arranged closer to a vertical plane in which a distal, orfront side 48 of thehousing 20, opposite theproximate side 46 of thehousing 20 adjacent to the vertical plane in which thehandle 30 extends and retracts, is located. Each of theadjustable rollers 42 includes a wheel, ball, caster, or other suitable rolling device that rotates about an axis of rotation having an adjustable rolling direction, which pivots or otherwise changes in response to a change of direction in which the carry-onbag 18 is rolling while theadjustable rollers 42 are in contact with the ground. Thus, theadjustable rollers 42 can maintain contact with the ground and allow thedistal side 48 of the carry-onbag 18 to be turned or otherwise steered while the carry-onbag 18 is rolling on all of therollers distal side 48 of thehousing 20 were replaced with in-line rollers. In other words, and with reference toFIG. 3 , which is a view looking up at an embodiment of thebottom surface 44 of thehousing 20, theadjustable rollers 42 rotate about an axis 50, which can pivot in the directions indicated byarrow 52 depending upon the direction in which the carry-onbag 18 is being steered while theadjustable rollers 42 are in contact with the ground. - According to alternate embodiments, however, all of the rollers extending away from the
bottom surface 44 of the carry-onbag 18 can beadjustable rollers 42, as shown inFIG. 4 . In other words, the carry-onbag 18 lacks anyinline rollers 40, and can be pivoted in any direction. - The plurality of rollers provided to each of the
luggage pieces luggage system 10FIG. 1 can be independently selected to include a plurality of in-line rollers 40, a plurality ofadjustable rollers 42, or a plurality of in-line rollers 40 and a plurality ofadjustable rollers 42. For example, as illustrated inFIGS. 1 and 3 , thefirst luggage piece 12 can include a plurality of in-line rollers 40 arranged along aproximate side 46 of thehousing 20. Thefirst luggage piece 12 also includes a plurality ofadjustable rollers 42 arranged adjacent to thedistal side 48 of the housing. The in-line rollers 40 of thefirst luggage piece 12 allow thefirst luggage piece 12 to track in a substantially straight line, while theadjustable rollers 42 allow the first luggage piece to be turned in a manner similar to a car, where theadjustable rollers 42 allow thedistal side 48 to be steered while the in-line wheels 40 follow. - In contrast, the
other luggage pieces luggage system 10 collectively forming the joinedunit 22 illustrated inFIG. 1 can each include a plurality ofadjustable rollers 42, such as four, arranged along thebottom surface 44 of the housing as illustrated inFIG. 4 , for example. According to such an embodiment, theluggage pieces adjustable rollers 42, without any in-line rollers 40, to allow theluggage pieces line rollers 40. - In use, the
luggage piece 12 can be positioned immediately adjacent to another luggage piece 14 (e.g., physically abutting against each other). The distal side 48 (FIGS. 2 and 3 ) of theluggage piece 12 can be placed against, or at least opposing thedistal side 48 of theluggage piece 14. Thus, theproximate side 46 of theluggage piece 12 adjacent to thehandle 30 forms a first terminal end of the joinedunit 22, and theproximate side 46 of theluggage piece 14 adjacent to thehandle 30 provided to thatluggage piece 14 forms another terminal end of the joinedunit 22 along a longitudinal axis. Arranged in such a manner, thehandle 30 provided to eachluggage piece handle 30 regardless of which end a user is standing next to. One, or a plurality oftethers 26 can be extended between theluggage piece 12 and theluggage piece 14, and the mating portion of the fastening system supported by the distal end of thetether 26 introduced to theconnection portion 24 provided to the housing of theluggage piece 14, thereby coupling theluggage pieces FIG. 1 , fourtethers 26 are used to couple theluggage pieces tether 26 on eachlateral side 36 of thehousing 20, and twotethers 26 extending between atop surface 58 of each of theluggage pieces tethers 26 suitable to couple theluggage pieces unit 22 can be utilized without departing from the scope of the present invention. - In a like manner, the
luggage piece 16 can also be positioned adjacent to theluggage piece 14, and coupled thereto with a plurality oftethers 26 to form a joinedunit 22 comprising threeluggage pieces FIG. 1 . With the in-line rollers 40 arranged at one longitudinal end of the joinedunit 22, the joinedunit 22 can be pulled by the retractable belt handle 54 and follow, tracking in a substantially straight line as a result of the fixed steering direction of the in-line rollers 40. Even embodiments with allluggage pieces adjustable rollers 42, however, can also be pulled in a straight line, but also have the ability to be pivoted about a fixed point as well. The other terminal end of the joinedunit 22, adjacent to theadjustable rollers 42 provided to theproximate side 46 of theluggage piece 16 as shown inFIG. 1 , can be steered through adjustment of the rolling direction of theadjustable rollers 42 without dragging or skidding fixed-rolling-direction rollers in a direction other than their fixed rolling direction.
