Abstract

  The bag assembly is composed of a first bag and a second bag, and the first bag and the second bag are connected to each other by an accessory, so that the bag assembly is moving and stationary even in the upright and inclined positions. Even inside, self-stability can be provided.

Description

  Some conventional bags, such as carry-on bags and movable duffel bags, are provided with a roller on the bottom of the bag so that travelers can easily carry them. However, it is often necessary for a traveler to carry two or more movable bags at the same time. When a traveler needs to carry two movable bags, it generally requires both hands. As a result, while carrying two or more large and heavy bags, travelers can answer mobile phone calls, look for cash or keys from pockets or purses, and pull infants' hands. I think it is difficult or impossible to do other things.

  Furthermore, in many situations, travelers find it difficult to handle a large number of bags simultaneously. For example, it is difficult to safely transport two large bags when moving up and down stairs or escalators, or to transport both bags at a narrow doorway. This is particularly difficult when the traveler is small and one or both of the bags are large and heavy. This type of difficulty is doubled when it is necessary to carry more than two bags.

  The features and advantages of the present invention will become apparent from the appended claims, the following detailed description of one or more example embodiments, and the corresponding figures.

  FIG. 1 depicts an example embodiment of a bag assembly 100 that includes a carry-on bag 102 and a third bag 106 connected to a trailing bag 104. Further, the bags 102, 104, 106 are connected such that the majority of the weight of the assembly 100 is on the carry-on bag 102 and the caster of the subsequent bag 104. The assembly 100 is self-stabilizing while moving and stationary, and in particular, a traveler does not need to have a handle 236 to maintain the assembly 100 in an upright or tilted position whether or not the assembly 100 is moving. . These and other features of the bag assembly 100 provide excellent stability and operability. Additional details regarding the components and steps used to form the movable bag assembly 100, as well as various operational characteristics of the bag assembly 100, are listed below.

  FIG. 2 depicts a perspective view of an embodiment of a bag called a carry-on bag 102. As shown, the carry-on bag 102 has a front surface 224, a rear surface 222, a top surface 226, a bottom surface 228, a left side 230, and a right side 232. As will be described in more detail below, in one embodiment, the carry-on bag 102 functions as the basis for a bag assembly that is easily transported, manipulated, and temporarily placed.

  In the present disclosure, the carry-on bag 102 is referred to as a first bag, a base bag, and a top bag 102. In one embodiment, the dimensions of the first bag 102 are approximately 23 inches high, 12 inches wide, and 10 inches deep. In other embodiments, other types and / or sizes of bags may be used as the first bag or the base bag.

  In the embodiment of FIG. 2, the upper surface of the first bag 102 features a soft handle 234. The left side 230 also features a soft handle. The first bag 102 includes two telescoping rigid upright members 240 and a substantially rigid gripping member 238 that connects the top of the upright member 240, but also includes a substantially rigid but telescoping handle 236. Features. In the embodiment of FIG. 1, the handle 236 is on the rear surface of the bag 102 and is located longitudinally in the middle between the left side and the right side.

  The first bag 102 also has a pair of casters 242, with one caster positioned at the left rear corner of the bottom surface of the bag 102 and the other caster positioned at the right rear corner of the bottom surface of the bag 102. In order to prevent stability and prevent movement when the first bag 102 is temporarily placed in the upright position in a state where the legs 244 and the casters 242 are in weight, the front edge of the bottom surface of the first bag 102 or its One or more legs 244 may be provided in the vicinity.

  FIG. 3 depicts a perspective view of an embodiment of a bag known as a movable duffle bag 104. As shown, the movable duffel bag 104 has a front surface 304, a rear surface 302, a top surface 306, a bottom surface 308, a left side 310, and a right side 312.

  In one embodiment, the movable duffel bag 104 is connected to the first bag 102 to form a bag assembly 100 that is easily transported, manipulated, and temporarily placed. Accordingly, in the present disclosure, the movable duffel bag 104 is referred to as a second bag or subsequent bag 104. In at least one embodiment, the trailing bag 104 is larger than the leading bag. In one embodiment, the dimensions of the second bag 104 are approximately 28.5 inches high, 13.5 inches wide, and 11.5 inches deep. In another embodiment, the dimensions of the second bag are approximately 33 inches high, 16 inches wide, and 13 inches deep. In another embodiment, the second bag may have a height greater than 47 inches. In other embodiments, other types and / or sizes of bags may be used as the second bag or subsequent bag 104. For example, the trailing bag 104 is the same size or smaller than the leading bag 102, and the mounting means 604 (FIG. 6) has dimensions accordingly to provide an appropriate weight distribution to stabilize the bags 102, 104. (Such as a long wearing strap).

  In the embodiment of FIG. 3, the upper surface of the second bag 104 features a soft handle 314. The second bag 104 features a rigid telescoping handle 316, a pair of casters 318 at the rear corners of the bottom of the bag, and one or more legs 320 at or near the front edge of the bottom. . When the second bag 104 is temporarily placed with the legs 320 and the casters 318 in contact with each other in the upright position, the legs 320 provide stability and prevent movement.

  FIG. 4 depicts a perspective view of an embodiment of a bag known as a shoulder bag 106. As shown, the shoulder bag 106 has a rear surface 402, a front surface 404, and a strap 406. As described in more detail below, in one embodiment, the shoulder bag 106 is connected to the first bag 102 along with the second bag 104 to form a bag assembly that is easily transported, manipulated, and temporarily placed. . Accordingly, in the present disclosure, the shoulder bag 106 is referred to as the upper bag or the third bag 106.

  In the embodiment of FIG. 4, strap 406 is dimensioned to snugly accommodate handle 236. Thus, the strap 406 is slid down the handle 236 until the third bag 106 rests on top of the first bag 102, after which the strap 406 prevents the upper bag 106 from detaching. In other embodiments, other types and / or sizes of bags may be used as the third bag 106 (laptop bag, purse, carry-all bag, gear bag, etc.). In general, the third bag 106 has a size that satisfies the aircraft requirements as an in-flight bag. For example, the third bag 106 may be small enough to fit under a typical aircraft seat. In other embodiments, the third bag 106 is omitted.

  5-8 depict side views of the components depicted in FIGS. Additionally, FIGS. 5-8 illustrate an embodiment of a method for forming a bag assembly 100 (FIG. 1).

  FIG. 5 shows a first bag 102, a second bag 104, and a third bag, each placed on the floor in an upright position, as seen, for example, after the traveler has retrieved the second bag 104 from the baggage turntable. A bag 106 is depicted. The process for grouping the bags to form a stable bag assembly 100 begins with the bag in this position. The traveler then separates handle 314 into two separate members.

  As shown in FIG. 6, the handle 314 includes a main handle strap 602 and a reinforcing handle strap 604. A snap-on sleeve or other temporary connection means is used to keep the main handle strap 602 and the reinforced handle strap 604 connected when the second bag 104 is used alone. However, if desired, the traveler can release the temporary connection means to separate the reinforcing handle strap 604 from the main handle strap 602, as shown by the arrow 606 in FIG.

  In one embodiment, the two ends of the main handle strap 602 are connected to the top surface of the second bag 104 at two points on or near the left and right edges of the top surface 306 of the bag 104, whereas the reinforcement handle. The two ends of the strap 604 are connected to an upper portion 322 (such as one third from the top) on the rear surface of the second bag 104. For example, the two ends of the reinforcing handle strap 604 are connected at two points at or near the upper edge of the rear surface 302. In one embodiment, the two attachment points of the reinforced handle strap 604 are at approximately equal distances from the longitudinal center of the second bag 104, and the two attachment points are at least the upright member 240 of the handle 236 of the first bag 102. They are at the same distance from each other. In other embodiments, other forms of upright parts, handles, and / or straps may be used.

  After the traveler has separated the reinforcing handle strap 604 from the main handle strap 602, the traveler lifts the reinforcing handle strap 604 over the grip 238 of the handle 236, as indicated by arrow 608. A telescoping handle 236 may be stored to facilitate this operation.

  As shown in FIG. 7, the traveler slides the reinforcing handle strap 604 under the handle 236 and / or extends the handle 236 up in the reinforcing handle strap 604 to provide the second bag 104. Is connected to the first bag 102. Accordingly, the reinforced handle strap 604 and the handle 236 function as mounting members and are referred to as such. Similarly, the reinforcing handle strap 604 may be referred to as a mounting strap 604.

  9, a top view of the form of the first bag 102 and the second bag 104 shown in FIG. 7 is drawn, and the second bag 104 is attached to the first bag 102, but the third bag 10 is can not see. As shown, when the traveler attaches the second bag 104 to the first bag 102 with the reinforcing handle strap 604, the reinforcing handle strap 604 extends into three sections, each extending from the second bag 104 to the periphery of the handle 236. It has a first section 604A and a third section 604C present and an intermediate second section 604B hung on the handle 236. In one embodiment, the first section 604A and the third section 604C are approximately the same length 902, which is approximately twice the length 904 of the section hung on the handle 236. For example, sections 604A and 604C are approximately 10 inches long and section 604B is approximately 6 inches long. The distance between the attachment points of the second bag 104 for sections 604A and 604C is also about 6 inches 904. The relatively wide middle section, together with the attachment point of the relatively wide second bag 104, helps to prevent the left and right sides of the second bag 104 from rising from the first bag 102, so that Improve the stability of the assembly 100. In other embodiments, other dimensions and / or ratios may be used. For example, the width of the rigid handle 236 of the top bag 102 may be longer than 6 inches or shorter than 6 inches (single pillar, etc.), and the mounting strap may be longer or shorter accordingly. Thus, the movable bag assembly 100 uses a mounting strap 604 having a length proportional to the distance from the trailing bag 104 to the periphery of the handle 236 to prevent the trailing bag 104 from slipping off the leading bag 102.

  Referring again to FIG. 7, the traveler detaches the third bag 106 from the assembly 100 by sliding the strap 406 down below the handle 236 and placing the third bag 106 on the top surface of the first bag 102 and the reinforcing handle strap 604. You may attach to. Adding the weight of the third bag 106 to the reinforcing handle strap 604 improves the stability of the bag assembly 100. The additional weight of the third bag 106 also contributes to the overall stability of the bag assembly 100 depending on the weight and angle of the other bags. For example, if the trailing bag 104 is very heavy and the leading bag 102 is very light, the third bag 106 above the top surface of the leading bag 102 exerts a beneficial downward force in front of the casters 242 of the first bag 102. To prevent the first bag 102 from returning to the upright position.

  Further, as described above, different types of articles may be used as the third bag 106. For example, a box or parcel may be placed on the upper surface of the first bag 102 to function as the third bag 106, and the movable bag assembly 100 may function as a self-stabilizing cart for carrying the box or parcel. The third bag 106 may or may not include the strap 406.

  When the handle 236 is extended in the reinforced handle strap 604, the assembly substantially takes the form shown in FIG. 7, with the first bag 102 in the upright position and the second bag 104 in the first bag. It leans on 102. In this form, most of the weight of the second bag 104 rests behind the caster 318. Therefore, the reinforcing handle strap 604 is firmly drawn by gravity to the front surface of the upright member 240 and the upper surface of the first bag 102. The reinforced handle strap 604 is configured to hold the second bag 104 in contact with at least a portion of the first bag 102 such that the second bag 104 is removed from the first bag 102 while the bag assembly 100 is moving. Prevent slipping and leaving. In one embodiment, the reinforced handle strap 604 holds the top back edge of the second bag 104 substantially adjacent to the top back edge of the first bag 102. In other embodiments, the mounting member causes the second bag 104 to slide further a short distance from the first bag 102. However, it is generally preferred to maintain the top surface of the second bag 104 within a distance, such as approximately 2 inches from the top surface of the first bag 102, so as to obtain the weight distribution advantage described below.

  Referring again to FIG. 8, the bag assembly 100 is depicted in an inclined configuration. That is, (a) the reinforcing handle strap 604 of the second bag 104 is wound around the handle 236 of the first bag 102, and (b) the third bag 106 is in the first bag with the strap 406 accommodating the handle 236. (C) A state in which both the first bag 102 and the second bag 104 have their casters 242 and 318 grounded, with the legs 244 and 320 floating from the floor. (D) at least a portion of the rear surface of the second bag 104 is in contact with at least a portion of the front surface of the first bag 102. In embodiments that do not include the third bag 106, the assembly 100 is considered fully assembled when in the previous configuration without the third bag 106.

  The reinforced handle strap 604 is dimensioned to mate with the handle 236 when the second bag 104 is positioned next to the first bag 102. Although the reinforced handle strap 604 is generally flexible and substantially inelastic, the strap 604 may have some elasticity. Consequently, when the first bag 102 is tilted forward from the upright position to the tilted position shown in FIG. 8, the second bag 104 slides off the front surface of the first bag 102 while the assembly 100 is moving and stationary. The separation from the first bag 102 is substantially prevented. For example, in the embodiment of FIG. 8, the relative positions of the top surfaces of the first bag 102 and the second bag 104 may vary by less than 5 percent of the height of the first bag 102 (such as approximately 1 inch). In other embodiments, depending on the size and weight of the subsequent bag 104, the mounting means 604 provides some positional change to maintain balance.

  As shown in FIG. 8, when the first bag 102 and the second bag 104 are slanted, that is, inclined, most of the weight of the second bag 104 is applied to the front of the caster 318. As a result, the weight of the second bag 104 causes the second bag 104 to be firmly drawn to the first bag 102, and the second bag 104 is prevented from unexpectedly returning to the upright position. In addition, a substantial portion of the weight of the assembly 100 is generally placed in front of the casters 242 to prevent the first bag 102 from returning to the upright position. As will be explained in detail below, this tendency to keep the bag in a tilted or forward-turned position is called internal pitch stability or self-stability.

  In one embodiment, the contact area where the front surface 222 of the first bag 102 contacts the rear surface 302 of the second bag 104 is greater than 75 percent of the front surface 224 of the first bag 102 and greater than 60 percent of the rear surface 302 of the second bag 104. Cover. This contact area helps to hold the second bag 104 so that it does not slip relative to the first bag 102.

  Thus, when the packaging of the bags 102, 104 is substantially complete and in the form of the position depicted in FIG. 8, the bag assembly 100 tends to remain in this position, and a portion of the weight of the assembly is It is supported by casters 242 and the rest is supported by casters 318. As a result, once the assembly is complete, the traveler does not have to make an effort to put the assembly together and in place. The traveler can also easily move the assembly 100 with one hand. Further, whether stationary, moving, or slanted, the assembly 100 is fully self-stabilizing and continues to follow a prescribed course without both hands or other external assistance.

  In addition, in some embodiments, most of the weight of the assembly 100 is placed in front of the casters 242 in the completed transfer ready position depicted in FIG. For example, depending on the weight of each bag and the weight distribution of each bag, approximately 20 to 40 percent of the weight of the assembly 100 is placed in front of the caster 242 of the first bag 102.

  In addition, the handle 236 provides an important leverage and the reinforced handle strap 604 prevents the second bag 104 from shifting from a position above the first bag 102. As a result, it is generally easy to press the handle 236 to lift the caster 318 completely off the ground. For example, if the weight is well distributed in the bag, it is easy for a 100 pound traveler to perform this operation with one hand on a bag assembly 100 weighing 100 pounds or more. Moreover, when the traveler depresses the handle 236 further, the weight is further shifted in front of the caster 242. Therefore, a traveler can easily maintain the balance of the entire assembly 100 on the caster 242 in the same manner as operating a stroller on stairs, escalators, and the like. Therefore, when the assembly 100 is balanced on the caster 242 of the top bag 102, it is more difficult to handle one turn at a turn, stairs, lift escalator, or two conventional bags one by one. The traveler feels it is very easy to manipulate the entire assembly 100 in a variety of other obstacles. Further, since the assembly 100 is not wider than the maximum width bag of the assembly 100, it is easy to operate the assembly 100 with a congested narrow doorway or passage.

  When the traveler does not want to move the assembly 100, the traveler need only return the first bag 102 to the upright position so that the legs 244 contact the ground and bear a portion of the weight of the assembly 100.

  Also, as described above, the manner in which the reinforced handle strap 604 connects the first and second bags together is that the left and right sides of the second bag 104 are raised and separated from the first bag 102 when the assembly 100 is in a movable configuration. Help prevent that. In other words, the reinforcing handle strap 604 prevents the second bag 104 from rotating or rotating with respect to the first bag 102 on the longitudinal axis. For example, in the embodiment of FIG. 8, when the packaging of the first bag 102 and the second bag 104 is substantially complete, the reinforced handle strap 604 may cause the second bag 104 to exceed 5 degrees relative to the first bag 102. Prevent turning. In another embodiment, the first bag may turn up to 30 degrees relative to the first bag. This type of stability of the assembly 100 is referred to as internal roll stability. In contrast, the overall resistance of the assembly 100 to rotation about its own longitudinal axis is largely determined by the distance between the casters on the bottom surface of the first bag 102, and this type of stability is related to external roll stability. be called.

  The assembly 100 also exhibits good internal and external pitch stability. In this disclosure, internal pitch stability refers to the tendency of both bags 102, 104 to maintain the same tilt angle relative to each other when the first and second bags 102, 104 are in a movable configuration. In other words, even when the traveler does not have the handle 236, or other parts of the first bag 102 or the second bag 104, the mounting member, weight distribution, and other features can cause one bag to become the other bag. It acts to resist the force of tilting up and down. Good internal pitch stability is one of the attributes that facilitates lifting the caster 318 by depressing the handle 236. External pitch stability refers to the tendency of the finished assembly 100 to try to hold all four casters 242, 318 on the ground.

  Further, the assembly 100 exhibits good internal and external yaw stability. In this disclosure, internal yaw stability refers to the tendency of the first and second bags 102, 104 to attempt to maintain the same relative alignment about the longitudinal axis. In other words, considering the contact area 802 between the first and second bags 102, 104, the front surface 304 of the second bag 104 tends not to rotate with respect to the rear surface 222 of the first bag 102. External yaw stability refers to the tendency of the assembly 100 to go straight when all four casters are moving in contact with the ground. The characteristics of pitch, roll, and yaw stability exhibited by the assembly 100 contribute to self-stabilization of the assembly 100 during movement and at rest, whether or not the bags 102, 104 are diagonal. Using alternative attachment means such as one or more “Velcro®” straps, straps with snaps or zippers, and straps of the subsequent bag 104 that are attached to and detached from the corresponding straps of the leading bag 102 Note that the components of assembly 100 are coupled. The strap may or may not be adjustable to provide a balance / leverage action suitable for bags loaded with different weights, and functions as a reinforcing strap when not used to form the bag assembly 100.

  FIG. 10 depicts a rear view of another embodiment of the carry-on bag 1040 and a front view of another embodiment of the movable duffel bag 1050. The carry-on bag 1040 is also referred to as a leading bag or a first bag 1040. The movable duffel bag 1050 is also referred to as a trailing bag or a second bag 1050. As shown, an engagement strap 1042 is attached to the front surface of the first bag 1040 and a corresponding engagement hook 1052 is attached to the back surface of the second bag 1050. The engagement strap 1042 is made of fabric, leather, plastic, or other suitable material. The engagement hook 1052 is made of metal, plastic, or other suitable material.

  The engagement strap 1042 is sized to accommodate the engagement hook 1052. For example, the upper portion 1054 of the engagement hook 1052 is approximately 4 inches wide, and the opening 1044 between the engagement strap 1042 and the rear surface of the first bag 1040 is substantially the same width as the upper portion 1054. The relatively wide engagement hook 1052 tends to prevent the left and right sides of the second bag 1050 from moving away from or rising from the first bag 1040 when engaged with the engagement strap 1042. The opening 1044 is also referred to as an engagement slot 1044. In other embodiments, other dimensions may be used.

  FIG. 11 shows a side view of the bags 1040, 1050 in the first position. To initially connect the first bag 1040 and the second bag 1050 into a stable bag assembly 1000 (FIGS. 12 and 13) or a bag set, the traveler can connect the first bag 1040 and the second bag 1050 with each other. Tilt backward slightly as shown. The traveler then inserts the tip 1056 of the engagement hook 1052 into the engagement slot 1044.

  FIG. 12 depicts a side view of upstanding bags 1040 and 1050 as a bag assembly 1000. As shown, when the first bag 1040 and the second bag 1050 return to the upright position, the engagement hook 1052 holds the bag together. Therefore, the engagement hook 1052 and the engagement strap 1042 are called mounting members.

  FIG. 13 depicts a side view of bags 1040 and 1050 tilted as a bag assembly 1000. When the first bag 1040 is tilted away from the second bag 1050, the engagement hook 1052 slides down into the engagement slot 1044 until the inner upper portion 1054 of the engagement hook 1052 engages the engagement strap 1042. . In the oblique orientation, at least a part of the weight of the second bag 1050 is applied in front of the caster 1058 of the second bag 1050, so that the rear surface of the second bag 1050 is pressed against the front surface of the first bag 1040 by gravity. As a result, similar to the embodiment of FIG. 8, in this configuration, the bag assembly 1000 is self-stabilized and can be easily moved with one hand. The handle of the first bag 1040 is also used to lift the caster 1058 from the ground, which provides good operability substantially as described above with respect to FIGS.

  14-17 illustrate side views of another embodiment of the carry-on bag 1402 and the movable duffle bag 1404 at different stages of another method for forming the bag assembly 1400. In the illustrated embodiment, the carry-on bag 1402 and the movable duffle bag 1404 include two or more strap sets 1406, 1410 with detachable connectors 1408, 1412 coupled to the middle portion of the straps 1406, 1410. . The connectors 1408 and 1412 are configured to be removed and reconnected to the accommodating connector portion of either the same bag or the adjacent bag. That is, one end of the straps 1406 and 1410 is attached to the upper part of the rear surface of the bag 1402 and 1404, and the middle end of the straps 1406 and 1410 terminates at a part of the connectors 1408 and 1412. Another end of the straps 1406 and 1410 is attached to the upper front portion of the bag 1402 and 1404, and another intermediate end of the straps 1406 and 1410 terminates at another portion of the connectors 1408 and 1412. When a portion of the connectors 1408, 1412 is connected, the straps 1406, 1410 extend back and forth on the top surfaces of the respective bags 1402, 1404. In addition, a portion of the connector 1412 of the duffel bag 1404 is connected to a corresponding portion of the connector 1408 of the carry-on bag 1402 or vice versa. The straps 1406 and 1410 and the connectors 1408 and 1412 are collectively referred to as a mounting member here.

  The mounting member 2302 includes an end 2306 that is L-shaped, U-shaped, cotter pin-shaped, or has another suitable shape that fits at least the edge of the handle 1912 or 1916. As shown in FIG. 24, the mounting members 2102, 2302 extend with the ends 2106, 2306 so that the mounting members 2102, 2302 fit under the handles 1912, 1916 of each suitcase 1902, 1904. A substantially planar portion is included between the portion 2304. Other suitable forms of mounting members 2102, 2302 may be used, such as VELCROR, snaps, and / or one or more straps, etc. Although the illustrated embodiment of the extension 2304 has a rectangular shape, the extension 2304 may have any suitable shape, such as an oval, a square, or a circle.

  FIG. 25 depicts a perspective view of an embodiment of a bag called a carry-on suitcase 1902. As shown, the carry-on suitcase 1902 has a front surface 2502, a rear surface 2504, an upper surface 2506, a bottom surface 2508, a left side 2510, and a right side 2512. As will be described in more detail below, in one embodiment, two or more suitcases 1902, 1904 (FIG. 19) are connected by a stabilizer 1908 to facilitate transport, manipulation, and temporary placement. 1900 is formed. In this disclosure, suitcases 1902, 1904 are referred to as suitcases or bags.

  In the embodiment of FIG. 25, the upper surface of the suitcase 1902 features a soft handle 1916. The left side 2510 also features a soft handle. The first suitcase 1902 also includes a substantially rigid telescopic handle 1910 that includes two telescopic, rigid upright members 1914 and a substantially rigid grip member 2520 that connects the top of the upright members 1914. It is characterized by. In the embodiment of FIG. 19, the handle 1910 is located on the rear surface of the suitcase 1902 and extends longitudinally in the middle between the left side and the right side. In other embodiments, the handle 1910 is attached to a single rigid retractable upright member 1914 instead of two retractable upright members 1914.

  The suitcase 1902 has a pair of fixed or swivel casters 1920, one caster located at the left rear corner of the bottom of the suitcase 1902 and the other caster located at the right rear corner of the bottom of the suitcase 1902. ing. To provide stability and prevent movement when the suitcase 1902 is temporarily placed in an upright position where the weight rests on the legs 2524 and the casters 1920, at or near the front edge of the bottom surface of the suitcase 1902 One or more legs 2524 are also provided. Alternatively, swivel casters may be provided before and after the suitcase.

  In order to balance the bag assembly 1900, the suitcase 1904 is generally the same size as the suitcase 1902, a larger size, and / or a weight equal to or heavier than the suitcase. Stabilizer 1908 is adjusted as necessary to balance the bag assembly 1900 in an upright or oblique position with the casters 1918, 1920 of both suitcases 1902, 1904 in contact with the ground. If the stabilizer 1908 is too tight, the caster 1920 of the suitcase 1904 floats off the ground, making the bag assembly 1900 unstable. If the stabilizer 1908 is too loose, it is difficult to balance the suitcases 1902, 1904 so that the bag assembly 1900 is self-stabilizing. Stabilizer 1908 provides a wide range of adjustments to stabilize the center of gravity for suitcases of various sizes and weights that balance these suitcases in tilted and upright positions.

  26-29 depict side views of a bag 1902, 1904 and an embodiment of a method for forming a bag assembly 1900 (FIG. 19). Instructions in accordance with an embodiment of a method for forming a bag assembly 1900 may be included in the stabilizer 1908 packaging, posted at the location where the stabilizer 1908 is sold, and / or a computer-based information network such as the Internet. Available through another source, such as the manufacturer's website accessed via

  In FIG. 26, for example, a first suitcase 1902 and a second suitcase 1904 standing upright on the floor, which are positions after the traveler has collected the second suitcase 1904 from the baggage turntable, are depicted. Yes. The process for grouping suitcases to form a stable bag assembly 1900 begins with suitcases 1902, 1904 in this position. The rear surface of the suitcase 1904 is adjacent to the front surface of the suitcase 1902. One of the slots 1108 (FIG. 21A) of the stabilizer 1908 is placed on the retractable handle 1910 of the suitcase 1902.

  FIG. 27 shows a state in which the free end portion 2106 (FIG. 21A) of the stabilizer 1908 is pulled out under the handle 1912 of the suitcase 1904 to prepare for fitting with the handle 1912 on the upper surface of the suitcase 1904. FIG. 28 shows the stabilizer 1908 pulled straight through the handle 1912, and FIG. 29 shows the stabilizer so that the end 2106 (FIG. 21A) of the mounting member 2102 mates with one edge of the slot 2108. A state 1908 is folded on the handle 1912.

  In another embodiment, the traveler engages the handle 1910 on the top surface of the first bag 1904 with one end 2106 (FIG. 24) of the stabilizer 2300 (FIG. 24) and the handle 1916 on the top surface of the second bag 1902. Can be mated with another end 2306 of the stabilizer 2300.

  When one of the slots 2108 is engaged with the handle 1910 or the handle 1916 is engaged with the mounting member 2302 (FIG. 23), the first suitcase 1902 is in the upright position, and the second suitcase 1904 is the first suitcase. Leaning on 1902. In this form, most of the weight of the second suitcase 1904 is behind the caster 1920. As a result, the stabilizers 1908 and 2300 are firmly drawn to the handles 1912 and 1910 or 1916 by weight.

  The stabilizers 1908 and 2300 hold the second suitcase 1904 in contact with at least a portion of the first suitcase 1902, and the second suitcase 1904 is in front of the first suitcase 1902 while the bag assembly 1900 is moving. Prevent sliding off or leaving. In some embodiments, the stabilizers 1908, 2300 hold the upper back edge of the second suitcase 1904 substantially adjacent to the upper rear edge of the first suitcase 1902. In other embodiments, the stabilizers 1908 and 2300 cause the second suitcase 1904 to slide down a shorter distance on the rear surface of the first suitcase 1902. However, it is generally preferred to retain the upper surface of the second suitcase 1904 within a distance, such as approximately 2 to 4 inches, on the upper surface of the first suitcase 1902 to obtain the benefits of weight distribution as described below.

  As shown in FIG. 19, when the first suitcase 1902 and the second suitcase 1904 are slanted, that is, tilted, most of the weight of the second suitcase 1904 is behind the caster 1920. . As a result, the second suitcase 1904 is firmly pressed against the first suitcase 1902 by the weight of the second suitcase 1904, and the second suitcase 1904 is prevented from unexpectedly returning to the upright position. Further, typically a significant portion of the weight of assembly 1900 rests behind caster 1920 to prevent suitcase 1902 from returning to the upright position. As described in more detail below, this tendency to maintain the suitcase in an oblique or tilted position is referred to as internal pitch stability or self-stability.

  Thus, once the suitcases 1902, 1904 have been substantially packed into the position depicted in FIG. 19, the bag assembly 1900 tends to maintain this position, with a portion of the weight of the assembly being reduced. It is supported by the caster 1918 of the suitcase 1902 and the rest is supported by the caster 1920 of the suitcase 1904. As a result, once the assembly 1900 is complete, the traveler does not have to make an effort to keep the assembly in place together. Travelers can also easily move the assembly 1900 with one hand. In addition, the assembly 1900, whether stationary, moving, or tilted, is fully self-stabilizing and has a prescribed course during movement without both hands or other external assistance. Continue to proceed.

  In addition, in certain embodiments, most of the weight of the assembly 1900 rests behind the caster 1920 in the completed move ready position depicted in FIG. For example, based on the weight of each suitcase and the weight distribution of each suitcase, approximately 20 to 40 percent of the weight of the assembly 1900 is placed behind the caster 1920 of the suitcase 1904.

  Further, the handle 1910 provides an important lever action and the stabilizers 1908, 2300 prevent the second suitcase 1904 from shifting from a position above the first suitcase 1902. As a result, it is generally easy to press the handle 1910 to lift the caster 1920 completely off the ground. For example, if the weight is well distributed in a suitcase, it is easy for a 1910 pound traveler to perform this operation with one hand on a bag assembly 1900 weighing over 1900 pounds. In addition, as the traveler further depresses the handle 1910, more weight shifts behind the caster 1920. Thus, a traveler can easily maintain the balance of the entire assembly 1900 on the caster 1918, similar to operating a stroller on stairs, escalators, and the like. Therefore, once the assembly 1900 is balanced on the caster 1918 of the top suitcase 1902, the traveler can handle one turn at a turn, stairs, lift escalator, and two or more conventional bags, one by one. In various other obstacles that are more difficult to manipulate, the entire assembly 1900 feels very easy to manipulate. Further, since the assembly 1900 is not wider than the full width suitcase of the assembly 1900, it is easy to operate the assembly 1900 in a crowded or narrow doorway or passageway. Alternatively, when the suitcase 1902, 1904 includes a swivel caster, no downward pressure is required to operate the bag assembly 1900 in a confined space.

  When a traveler does not want to move the assembly 1900, the first suitcase 1902 need only be returned to the upright position so that the legs 2524 contact the ground and bear a portion of the weight of the assembly 1900.

  In addition, as described above, the stabilizers 1908 and 2300 connect the first and second suitcases to each other so that the left and right sides of the second suitcase 1904 are raised from the first suitcase 1902 when the assembly 1900 is in a movable form. Helps prevent you from leaving. In other words, the stabilizers 1908 and 2300 prevent the second suitcase 1904 from rotating or rotating with respect to the first suitcase 1902 along the longitudinal axis. For example, in the embodiment of FIG. 26, when the packing of the first suitcase 1902 and the second suitcase 1904 is substantially completed, the stabilizers 1908 and 2300 are set to 5 degrees with respect to the first suitcase 1902. To avoid turning over. In another embodiment, the first suitcase may turn up to 30 degrees relative to the first suitcase. This type of stability of assembly 1900 is referred to as internal roll stability. In contrast, the overall resistance of the assembly 1900 to rotation about the longitudinal axis is largely determined by the distance between the casters on the bottom surface of the first suitcase 1902 and this type of stability is referred to as external roll stability. .

  The assembly 1900 also exhibits good internal and external pitch stability. In this disclosure, the internal pitch stability is the tendency of both suitcases 1902, 1904 to try to maintain the same tilt angle relative to each other when the first and second suitcases 1902, 1904 are in a movable configuration. Point to. In other words, even when the traveler does not have the handle 1910 or other parts of the first suitcase 1902 or the second suitcase 1904, the mounting member, weight distribution, and other characteristics It acts to resist the force of tilting up and down against the suitcase. Good internal pitch stability is one of the attributes that facilitates lifting the caster 1920 by depressing the handle 1910. External pitch stability refers to the overall tendency of assembly 1900 to try to hold casters 1918, 1920 on the ground.

  Further, the assembly 1900 exhibits good internal and external yaw stability. In this disclosure, internal yaw stability refers to the tendency of the first and second suitcases 1902, 1904 to attempt to maintain the same relative alignment about the longitudinal axis. In other words, considering that the contact is between the first and second suitcases 1902, 1904, the rear surface of the second suitcase 1904 tends not to rotate relative to the front surface 2502 of the first suitcase 1902. External yaw stability refers to the tendency of assembly 1900 to go straight as all four casters move in contact with ground. The pitch, roll, and yaw stability exhibited by the assembly 1900 contributes to self-stabilization of the assembly 1900 during movement and at rest, regardless of whether the suitcases 1902, 1904 are diagonal.

  Referring to FIG. 30, another embodiment of a stabilizer 3002 is shown assembled in a pocket 3004 on the top surface of a suitcase 1902. One end of the stabilizer 3002 can be sewn into the pocket 3004 or otherwise fastened, and another end 3006 can be used to connect to another suitcase (not shown). The stabilizer 3002 is stored in the pocket 3004 when not in use. In other embodiments, the stabilizer 3002 is completely removable from the pocket 3004 and one end (not shown) of the stabilizer 3002 is configured to be attached to the handle 1910, 1916 or other suitable location of the suitcase 1902. In contrast, another end 3006 of the stabilizer 3002 is attached to an appropriate portion of another suitcase (not shown).

  FIG. 31 illustrates another embodiment of a Y-shaped stabilizer 3100 that can be used to form a bag assembly 1900 (FIG. 19). One mounting member 3110 of the stabilizer 3100 includes a triangular opening with a base located around the upright support of the retractable handle 1910.
