Definitions

  • Some conventional pieces of luggage such as carry-on bags and rolling duffel bags, may have rollers on the bottom to make the bags easier for travelers to transport.
  • travelers often need to transport two or more wheeled pieces of luggage simultaneously. If a traveler needs to transport two wheeled pieces of luggage, both hands are typically required. Consequently, while transporting two or more large, heavy pieces of luggage, the traveler may find it difficult or impossible to do other things, such as answering a cellular telephone call, retrieving cash or keys from a pocket or purse, holding the hand of a small child, etc.
  • Figure 1 depicts an example embodiment not forming part of the present invention comprising a luggage assembly 100 including carry-on bag 102 connected to a trailing bag 104, and a third bag 106. Moreover, the bags 102, 104, 106 are connected in a way that allows a majority of the weight of the assembly 100 to rest on the wheels of carry-on bag 102 and trailing bag 104. Assembly 100 is self-stabilized when in motion and when stationary, and in particular, a traveler does not need to hold handle 236 for the assembly 100 to remain upright or in an inclined position whether or not assembly 100 is in motion. These and other characteristics of luggage assembly 100 provide for excellent stability and maneuverability. Additional details concerning the components and steps used for creating a rollable luggage assembly 100, as well as various operating characteristics of luggage assembly 100, are provided below.
  • Figure 2 depicts a perspective view of an embodiment of a piece of luggage referred to as a carry-on bag 102 not forming part of the present invention.
  • carry-on bag 102 has a front 224, a back 222, a top 226, a bottom 228, a left side 230, and a right side 232.
  • carry-on bag 102 serves as the foundation for an assembly of bags that can easily be transported, maneuvered, and parked.
  • carry-on bag 102 may be referred to as a first bag, a base bag, or a leading bag 102.
  • first bag 102 the dimensions of first bag 102 are approximately 23 inches (58,42 cm) high, 12 inches (30,48 cm) wide, and 10 inches (25,4 cm) deep. In other embodiments, other types and/or sizes of bags may be used as the first bag or base bag.
  • first bag 102 features a soft handle 234.
  • Left side 230 can also features a soft handle.
  • First bag 102 also features a substantially rigid, yet extendable handle 236 that includes two extendable, rigid upright members 240, and a substantially rigid grip member 238 that spans the top of upright members 240.
  • handle 236 is situated at the back of bag 102, and is centered longitudinally between the left and right sides.
  • First bag 102 can also have a pair of wheels 242, with one wheel situated at the back left corner of the bottom of the bag 102, and the other wheel situated at the back right corner of the bottom of the bag 102.
  • One or more feet 244 may also be provided at or near the front edge of the bottom of first bag 102, to provide stability and prevent movement when first bag 102 is parked in an upright position with the weight resting on feet 244 and wheels 242.
  • FIG 3 depicts a perspective view of an embodiment of a piece of luggage known as rolling duffel bag 104 not forming part of the present invention.
  • rolling duffel bag 104 has a front 304, a back 302, a top 306, a bottom 308, a left side 310, and a right side 312.
  • rolling duffel bag 104 is connected to first bag 102 to create a luggage assembly 100 that can easily be transported, maneuvered, and parked. Accordingly, for purposes of this disclosure, rolling duffel bag 104 may be referred to as a second bag or a trailing bag 104. In at least one embodiment, the trailing bag 104 is larger than the leading bag. In one embodiment, the dimensions of second bag 104 are approximately 28.5 inches (72,39 cm) high, 13.5 inches (34,29 cm) wide, and 11.5 inches (29,21 cm) deep. In another embodiment, the dimensions of the second bag are approximately 33 inches (83,82 cm) high, 16 inches (40,64 cm) wide, and 13 inches (33,02 cm) deep.
  • the second bag may be greater than 47 inches (119,38 cm) high.
  • other types and/or sizes of bags may be used as the second bag or trailing bag 104.
  • the trailing bag 104 may be the same size as, or smaller than, the leading bag 102, with attachment means 604 ( Figure 6 ) dimensioned accordingly (e.g., a longer attachment strap) to provide a suitable weight distribution to stabilize the bags 102, 104.
  • second bag 104 features a soft handle 314.
  • Second bag 104 may also feature a rigid, extendable handle 316, along with a pair of wheels 318 at the back corners of the bottom of the bag, and one or more feet 320 at or near the front edge of the bottom.
  • Feet 320 may provide stability and prevent movement when second bag 104 is parked in an upright position on feet 320 and wheels 318.
  • Figure 4 depicts a perspective view of an embodiment of piece of luggage known as shoulder bag 106 not forming part of the present invention.
  • shoulder bag 106 has a back 402, a front 404, and a strap 406.
  • shoulder bag 106 may be connected to first bag 102 along with second bag 104 to create an assembly of bags that can easily be transported, maneuvered, and parked. Accordingly, for purposes of this disclosure, shoulder bag 106 may be referred to as a top bag or a third bag 106.
  • strap 406 is dimensioned to snugly receive handle 236.
  • strap 406 may be slid down handle 236 until third bag 106 rests on top of first bag 102, and strap 406 will thereafter prevent top bag 106 from being dislodged.
  • other types and/or sizes of bags may be used as the third bag 106 (e.g., a laptop bag, a purse, a carry-all bag, a gear bag).
  • the third bag 106 can be sized to meet airline requirements for carry-on bags.
  • the third bag 106 could be small enough to fit under a typical airline seat.
  • the third bag 106 may be omitted.
  • Figures 5-8 depict side views of the components depicted in Figures 2-4 .
  • Figures 5-8 illustrate an embodiment of a method for creating luggage assembly 100 ( Figure 1 ).
  • Figure 5 depicts first bag 102, second bag 104, and third bag 106 resting on the floor, each in an upright position, as they might be situated, for instance, after a traveler has retrieved second bag 104 from a baggage carousel.
  • the process for attaching the bags together in a manner to create a stable luggage assembly 100 may begin with the bags in this position.
  • the traveler may then separate handle 314 into two separate members.
  • handle 314 may include a main handle strap 602 and a reinforcement handle strap 604.
  • a sleeve with snaps, or any other temporary connection means may be used to keep main handle strap 602 and reinforcement handle strap 604 connected when second bag 104 is being used alone.
  • the traveler may release the temporary connection means, to allow the traveler to separate reinforcement handle strap 604 from main handle strap 602, as shown by arrow 606 in Figure 6 .
  • two ends of main handle strap 602 are connected to the top of second bag 104, at two points at or near the left and right edges of the top 306 of bag 104, while two ends of reinforcement handle strap 604 are connected to the upper portion 322 (e.g., the upper third) of the back of second bag 104.
  • the two ends of reinforcement handle strap 604 may be connected at two points at or near the top edge of the back 302.
  • the two attachment points for reinforcement handle strap 604 are approximately equal distances from the longitudinal center of second bag 104, and the two attachment points are situated at least as far apart from each other as are the upright members 240 of handle 236 of first bag 102.
  • Other embodiments may use other configurations of uprights, handles, and/or straps.
  • reinforcement handle strap 604 and handle 236 may serve as, and may be referred to as, attachment members.
  • reinforcement handle strap 604 may also be referred to as an attachment strap 604.
  • Figure 9 depicts a top view of the configuration not forming part of the present invention of first bag 102 and second bag 104 shown in Figure 7 with the second bag 104 attached to the first bag 102, but without third bag 10
  • reinforcement handle strap 604 may have three segments, namely, a first segment 604A and a third segment 604C, each of which extends from second bag 104 around handle 236, and an intermediate second segment 604B, which spans handle 236.
  • first segment 604A and third segment 604C are approximately the same length 902, and that length 902 is approximately twice the length 904 of the segment that spans handle 236.
  • segments 604A and 604C may be approximately 10 inches (25,40 cm) long, and segment 604B may be approximately six inches (15,24 cm) long.
  • the distance between the attachment points on second bag 104 for segments 604A and 604C may also be approximately six inches. (15,24 cm).
  • the relatively wide intermediate segment, in conjunction with the relatively wide attachment points on second bag 104, may provide increased stability for the luggage assembly 100 by helping to prevent the left or right side of second bag 104 from lifting away from first bag 102.
  • Other dimensions and/or proportions may be used in other embodiments.
  • the rigid handle 236 on the leading bag 102 could be wider than six inches (15,24 cm) or less than six inches (15,24 cm) (e.g., a single post), and the attachment strap could be longer or shorter, correspondingly.
  • a rollable luggage assembly 100 may thus use an attachment strap 604 that is proportionate in length to the distance from the trailing bag 104 to and around the handle 236 to prevent the trailing bag 104 from sliding too far down the leading bag 102.
  • the traveler may also attach third bag 106 to the assembly 100 by sliding strap 406 down handle 236 to rest third bag 106 on top of first bag 102 and reinforcement handle strap 604.
  • the added weight of third bag 106 on reinforcement handle strap 604 may provide increased stability for luggage assembly 100.
  • the added weight of third bag 106 may also contribute to the overall stability of luggage assembly 100, depending on the weight and angle of the other bags. For instance, if the trailing bag 104 was very heavy and the leading bag 102 was very light, a third bag 106 on top of the leading bag 102 could provide a beneficial force downward in front of the wheels 242 of the first bag 102 to prevent the first bag 102 from reverting to the upright position.
  • third bag 106 many different kinds of objects could be used as the third bag 106.
  • a box or package may be placed on top of first bag 102 to serve as the third bag 106, and the rollable luggage assembly 100 may also serve as a self-stabilized dolly for transporting that box or package.
  • Third bag 106 may or may not include strap 406.
  • the assembly may take on substantially the configuration shown in Figure 7 , with first bag 102 in an upright position and second bag 104 leaning against first bag 102. In this configuration, most of the weight of second bag 104 may rest behind wheels 318. The force of gravity may therefore pull reinforcement handle strap 604 firmly against the front of upright members 240 and the top of first bag 102. Reinforcement handle strap 604 is configured to retain second bag 104 in contact with at least a portion of first bag 102, and may prevent second bag 104 from sliding down or moving away from the front of first bag 102 while luggage assembly 100 is in motion. In one embodiment, reinforcement handle strap 604 keeps the top back edge of second bag 104 substantially adjacent to the top back edge of first bag 102.
  • the attachment member may allow the second bag 104 to slide a short distance further down the back of the first bag 102.
  • luggage assembly 100 is depicted in an inclined configuration. Specifically, (a) reinforcement handle strap 604 of second bag 104 is wrapped around handle 236 of first bag 102, (b) third bag 106 is resting on top of first bag 102 and reinforcement handle strap 604, with strap 406 receiving handle 236, (c) both first bag 102 and second bag 104 are inclined at an angle on their wheels 242, 318 with the feet 244, 320 elevated from the floor, and (d) at least a portion of the back of second bag 104 is in contact with at least a portion of the front of first bag 102. In embodiments that do not include third bag 106, the assembly 100 may be considered fully assembled when in the preceding configuration, but without third bag 106.
  • Reinforcement handle strap 604 is dimensioned to engage handle 236 when second bag 104 is situated next to first bag 102.
  • Reinforcement handle strap 604 is typically flexible but substantially inelastic, but strap 604 can also have some elasticity. Consequently, when first bag 102 is tilted forward from an upright position into the inclined position shown in Figure 8 , reinforcement handle strap 604 substantially prevents second bag 104 from sliding down the front of first bag 102 or moving away from first bag 102 while assembly 100 is in motion and stationary.
  • the relative positions of the tops of first bag 102 and second bag 104 may change by less than five percent of the height of first bag 102 (e.g., approximately one inch (2,54 cm)) in the embodiment of Figure 8 .
  • the attachment means 604 may provide for a larger or smaller change in position to maintain balance.
  • first bag 102 and second bag 104 are tilted or inclined as shown in Figure 8 , most of the weight of second bag 104 sits in front of wheels 318. Consequently, the weight of second bag 104 keeps second bag 104 firmly pressed against first bag 102, and prevents second bag 104 from accidentally reverting to the upright position. Furthermore, a sufficient portion of the weight of the assembly 100 typically rests in front of wheels 242 to prevent first bag 102 from reverting to the upright position. As described in greater detail below, this tendency for the bags to stay in inclined or pitched forward positions may be referred to as internal pitch stability or self-stabilizing.
  • the contact area where the front 222 of first bag 102 contacts the back 302 of second bag 104 covers more than seventy-five percent of the front 224 of first bag 102 and more than sixty percent of the back 302 of second bag 104. This contact area helps to keep second bag 104 from shifting relative to first bag 102.
  • luggage assembly 100 tends to remain in that position, with some of the weight of the assembly supported by wheels 242, and the rest supported by wheels 318. Consequently, once the assembly has been completed, the traveler need not expend any effort to keep the assembly together and properly positioned. The traveler may also easily move assembly 100 with a single hand. Furthermore, whether stationary or in motion, and whether tilted or not, the assembly 100 is completely self-stabilized and may continue on its established course with no hands or other external support.
  • handle 236 provides significant leverage, and reinforcement handle strap 604 prevents second bag 104 from shifting from its position on first bag 102. Consequently, it is typically easy to press down on handle 236 and lift wheels 318 completely off of the ground. For example, if the weight is well distributed within the bags, it may be easy for a 100 pound traveler to perform this operation with one hand on a luggage assembly 100 weighing in excess of 100 pounds. Additionally, the further down the traveler pushes handle 236, the more weight shifts in front of wheels 242. The traveler may therefore easily balance the whole assembly 100 on wheels 242 similar to maneuvering baby strollers over steps, escalators, etc.
  • the traveler may find it very easy to maneuver the entire assembly 100 around turns, over steps, up and down escalators, and through various other obstacles which would be more difficult to handle with two or more pieces of conventional luggage, one in each hand. Further, since assembly 100 is no wider than the widest bag in the assembly 100, it may be easy to maneuver assembly 100 through crowded or narrow openings or passages.
  • the traveler may simply return first bag 102 to the upright position, so that feet 244 contact the ground and bear some of the weight of assembly 100.
  • reinforcement handle strap 604 connects the first and second bags together helps to keep the left and right sides of second bag 104 from lifting or moving away from first bag 102 when assembly 100 is in the rollable configuration.
  • reinforcement handle strap 604 prevents second bag 104 from spinning or rotating along its longitudinal axis, relative to first bag 102.
  • reinforcement handle strap 604 prevents second bag 104 from rolling more than five degrees, relative to first bag 102, when first bag 102 and second bag 104 are substantially fully packed.
  • Another embodiment may allow the first bag to roll up to thirty degrees, relative to the first bag.
  • This type of stability for assembly 100 may be referred to as internal roll stability.
  • the resistance of the entire assembly 100 from rotating about its longitudinal axis may be determined largely by the distance between the wheels on the bottom of first bag 102, and that type of stability may be referred to as external roll stability.
  • Assembly 100 also exhibits good internal and external pitch stability.
  • internal pitch stability refers to the tendency of both bags 102, 104 to retain the same angle of inclination, relative to each other, when the first and second bags 102, 104 are in the rollable configuration.
  • the attachment members, the weight distribution, and other features work to resist forces which might otherwise cause one bag to lean up or down, relative to the other bag, even when a traveler is not holding onto handle 236 or any other part of the first bag 102 or second bag 104.
  • Good internal pitch stability is one of the attributes that makes it easy to lift wheels 318 by pressing down on handle 236.
  • External pitch stability refers to the tendency of the complete assembly 100 to keep all four wheels 242, 318 on the ground.
  • assembly 100 exhibits good internal and external yaw stability.
  • internal yaw stability refers to the tendency for the first and second bags 102, 104 to keep the same relative alignment for their longitudinal axes.
  • the front 304 of the second bag 104 tends not to rotate relative to the back 222 of the first bag 102.
  • External yaw stability refers to the tendency for assembly 100 to track straight when it is rolling on all four wheels. The characteristics of pitch, roll, and yaw stability exhibited by assembly 100 contribute to assembly 100 being self-stabilized when in motion and when stationary, whether bags 102, 104 are tilted or not.
  • components of assembly 100 can be coupled using alternative attachment means such as one or more Velcro straps, straps with snaps or zippers, and straps on the trailing bag 104 that disconnect and reconnect with corresponding straps on the leading bag 102.
  • the straps may or may not be adjustable to provide suitable balance/leverage for bags packed with different weights, and that may serve as reinforcement straps when not being used to form a luggage assembly 100.
  • Figure 10 depicts a rear view of another embodiment of carry-on bag 1040 not forming part of the present invention and a front view of another embodiment of rolling duffel bag 1050 not forming part of the present invention.
  • Carry-on bag 1040 may also be referred to as a leading bag or a first bag 1040.
  • Rolling duffel bag 1050 may also be referred to as a trailing bag or a second bag 1050.
  • a mating strap 1042 is affixed to the front of first bag 1040, and a corresponding mating hook 1052 is attached to the back of second bag 1050.
  • Mating strap 1042 may be made of textile, leather, plastic, or any other suitable material.
  • Mating hook 1052 may be made of metal, plastic, or any other suitable material.
  • Mating strap 1042 is dimensioned to receive mating hook 1052.
  • the top 1054 of mating hook 1052 may be approximately 4 inches (10,16cm) wide, and the opening 1044 between mating strap 1042 and the back of first bag 1040 may be substantially the same width as top 1054.
  • the relatively wide mating hook 1052, when engaged by mating strap 1042 may tend to prevent the left and right sides of second bag 1050 from moving or lifting away from first bag 1040.
  • Opening 1044 may also be referred to as a mating slot 1044.
  • Other dimensions may be used in other embodiments.
  • Figure 11 depicts a side view of bags 1040 and 1050 in a first position.
  • the traveler may lean first bag 1040 and second bag 1050 slightly backwards, as shown. The traveler may then insert the tip 1056 of mating hook 1052 into mating slot 1044.
  • Figure 12 depicts a side view of bags 1040 and 1050 upright in luggage assembly 1000. As depicted, when first bag 1040 and second bag 1050 are returned to upright positions, mating hook 1052 may keep the bags together. Accordingly, mating hook 1052 and mating strap 1042 may be referred to as attachment members.
  • Figure 13 depicts a side view of bags 1040 and 1050 tilted in a luggage assembly 1000.
  • first bag 1040 is tilted away from second bag 1050, mating hook 1052 slides down into mating slot 1044 until the inside top 1054 of mating hook 1052 engages mating strap 1042.
  • second bag 1050 may rest in front of the wheels 1058 of second bag 1050, so that gravity presses the back of second bag 1050 against the front of first bag 1040. Consequently, similar to the embodiment of Figure 8 , the luggage assembly 1000 may be self-stabilized in this configuration, and may be easily rolled with one hand.
  • the handle of first bag 1040 may also be used to lift wheels 1058 off of the ground, thereby allowing for good maneuverability, substantially as described above with regard to Figures 2-9 .
  • Figures 14-17 show side views of another embodiment of carry-on bag 1402 and rolling duffel bag 1404 in different stages of another method for creating a luggage assembly 1400 not forming part of the present invention.
  • carry-on bag 1402 and rolling duffel bag 1404 include two or more respective sets of straps 1406, 1410 with releasable connectors 1408, 1412 coupled at an intermediate portion along straps 1406, 1410.
  • Connectors 1408, 1412 are configured to be released and recoupled to a receiving connector portion either on the same bag or on the adjacent bag. That is, one end of straps 1406, 1410 are attached to the top back of bags 1402, 1404 and an intermediate end of straps 1406, 1410 terminates with a portion of connector 1408, 1412.
  • Straps 1406, 1410 are attached to the front top of bags 1402, 1404 and another intermediate end of straps 1406, 1410 terminates with another portion of connector 1408, 1412.

  • first suitcase 1902 When one of slots 2108 engages handle 1910, or handle 1916 engages attachment member 2302 ( Figure 23 ), first suitcase 1902 may be in an upright position and second suitcase 1904 may lean against first suitcase 1902. In this configuration, most of the weight of second suitcase 1904 may rest behind wheels 1920. The force of gravity may therefore pull stabilizer 1908, 2300 firmly against the handles 1912, and 1910 or 1916.
  • Stabilizers 1908, 2300 are configured to retain second suitcase 1904 in contact with at least a portion of first suitcase 1902, and prevent first suitcase 1904 from sliding down or moving away from the front of second suitcase 1902 while luggage assembly 1900 is in motion.

  • stabilizer 1908, 2300 may allow the first suitcase 1904 to slide a short distance further down the back of the second suitcase 1902.
  • first suitcase 1902 and second suitcase 1904 are tilted or inclined as shown in Figure 19 , most of the weight of second suitcase 1904 sits behind wheels 1920. Consequently, the weight of second suitcase 1904 keeps second suitcase 1904 firmly pressed against first suitcase 1902, and prevents second suitcase 1904 from accidentally reverting to the upright position. Furthermore, a sufficient portion of the weight of the assembly 1900 typically rests behind wheels 1920 to prevent suitcase 1902 from reverting to the upright position. As described in greater detail below, this tendency for the suitcases to stay in inclined or tilted positions may be referred to as internal pitch stability or self-stabilizing.
  • luggage assembly 1900 tends to remain in that position, with some of the weight of the assembly supported by wheels 1918 on suitcase 1902, and the rest supported by wheels 1920 on suitcase 1904. Consequently, once the assembly 1900 has been completed, the traveler need not expend any effort to keep the assembly together and properly positioned. The traveler may also easily move assembly 1900 with a single hand. Furthermore, whether stationary or in motion, and whether tilted or not, the assembly 1900 is completely self-stabilized and may continue on its established course while in motion with no hands or other external support.
  • handle 1910 provides significant leverage, and stabilizer 1908, 2300 prevents second suitcase 1904 from shifting from its position on first suitcase 1902. Consequently, it is typically easy to press down on handle 1910 and lift wheels 1920 completely off of the ground. For example, if the weight is well distributed within the suitcases, it may be easy for a 1910 pound traveler to perform this operation with one hand on a luggage assembly 1900 weighing in excess of 1900 pounds. Additionally, the further down the traveler pushes handle 1910, the more weight shifts behind wheels 1920. The traveler may therefore easily balance the whole assembly 1900 on wheels 1918 similar to maneuvering baby strollers over steps, escalators, etc.
  • the traveler may find it very easy to maneuver the entire assembly 1900 around turns, over steps, up and down escalators, and through various other obstacles which would be more difficult to handle with two or more pieces of conventional luggage, one in each hand. Further, since assembly 1900 is no wider than the widest suitcase in the assembly 1900, it may be easy to maneuver assembly 1900 through crowded or narrow openings or passages. Alternatively, when suitcases 1902, 1904 include swivel wheels, no downward pressure may be required to maneuver luggage assembly 1900 in tight spaces.
  • the traveler may simply return first suitcase 1902 to the upright position, so that feet 2524 contact the ground and bear some of the weight of assembly 1900.
  • stabilizer 1908, 2300 connects the first and second suitcases together helps to keep the left and right sides of second suitcase 1904 from lifting or moving away from first suitcase 1902 when assembly 1900 is in the rollable configuration.
  • stabilizer 1908, 2300 prevents second suitcase 1904 from spinning or rotating along its longitudinal axis, relative to first suitcase 1902.
  • stabilizer 1908, 2300 prevents second suitcase 1904 from rolling more than five degrees, relative to first suitcase 1902, when first suitcase 1902 and second suitcase 1904 are substantially fully packed.

  • This type of stability for assembly 1900 may be referred to as internal roll stability.
  • the resistance of the entire assembly 1900 from rotating about its longitudinal axis may be determined largely by the distance between the wheels on the bottom of first suitcase 1902, and that type of stability may be referred to as external roll stability.
  • Assembly 1900 also exhibits good internal and external pitch stability.
  • internal pitch stability refers to the tendency of both suitcases 1902, 1904 to retain the same angle of inclination, relative to each other, when the first and second suitcases 1902, 1904 are in the rollable configuration.

  • Good internal pitch stability is one of the attributes that makes it easy to lift wheels 1920 by pressing down on handle 1910.
  • External pitch stability refers to the tendency of the complete assembly 1900 to keep wheels 1918, 1920 on the ground.
