The assembly 100 It is not necessary to grasp the handle 236 in order to keep the assembly 100 upright or in an inclined position, especially when the traveler is moving or not moving. These and other features of the assembly 100 are provided for superior stability and operability. [0040] The term " assembly " used for various operational features of the travel bag assembly 100, as well as forming the durable travel bag assembly 100, It is provided for additional details on the elements and steps.
Figure 2 shows a perspective view of an embodiment of a portion of a suitcase referred to as a carrying bag 102. [ As shown, the portable bag 102 has a front 224, a back 222, an upper 226, a lower 228, a left 230 and a right 232. As described in more detail below, in some embodiments, the portable bag 102 is provided as a basis for a bag assembly that can be easily transported, manipulated, and stored.
For purposes of this disclosure, the portable bag 102 may be referred to as a first bag, a base bag, or a leading bag (102). In one embodiment, the dimensions of the first bag 102 are formed to a height of approximately 23 inches, a width of 12 inches, and a depth of 10 inches. In other alternative embodiments, bags of other types and / or sizes may be used as the first bag or base bag.
In the embodiment of FIG. 2, the upper side of the first bag 102 includes a soft handle 234. The left side 230 may also be configured as a flexible handle. The first bag 102 also includes two elongatable and rigid upstanding members 240 and a substantially rigid and extendible handle 240 that includes a substantially rigid grip member 238 that spans over the upright member 240. [ (236). In the embodiment of FIG. 1, the handle 236 is located at the back of the bag 102, centered longitudinally between the left and right sides.
The first bag 102 may also have a pair of wheels 242 with one wheel located at the rear left corner of the lower side of the bag 102 and the other wheels positioned at the rear of the lower side of the bag 102 And is located at the right corner. One or more foots 224 may be used to provide stability when the first bag 102 is placed in an upright position relative to the weight loaded on the foot 244 and the wheel 242, Or at or near the front of the lower side of the frame.
Figure 3 shows a perspective view of an embodiment of a portion of a suitcase known as a rolling duffel bag (104). As shown, the rolling duffel bag 104 has a front 304, a rear 302, an upper 306, a lower 308, a left 310 and a right 312.
In some embodiments, the rolling duffel bag 104 is connected to the first bag 102 to form a suitcase assembly 100 that can be easily transported, manipulated, and stored. Thus, for purposes of this disclosure, the rolling duffle bag 104 may be referred to as a second bag or trailing 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 formed to a height of approximately 28.5 inches, a width of 13.5 inches, and a depth of 11.5 inches. In yet another embodiment, the dimensions of the second bag are formed to a height of approximately 33 inches, a width of 16 inches and a depth of 13 inches. In another embodiment, the second bag may exceed 47 inches in height. In other alternative embodiments, bags of other types and / or sizes may be used as the second bag or trailing bag 104. [ For example, the trailing bag 104 may be the same size as or smaller than the leading bag 102, and thus may be attached to the back 102 to provide an appropriate weight distribution that provides stability to the bags 102, The dimensions of the means 604 (Figure 6) are formed (e.g., longer attachment straps).
In the embodiment of FIG. 3, the upper side of the second bag 104 includes a flexible handle 314. The second bag 104 also includes a rigid extendible handle 316, a pair of wheels 318 at the lower rear corner of the bag, and at least one foot 320 at or near the lower frontal side . The foot 320 provides stability and prevents movement when the second bag 104 temporarily raises to an upright position on the foot 320 and the wheel 318.
Figure 4 shows a perspective view of an embodiment of a portion of a suitcase known as a shoulder bag (106). As shown, the shoulder bag 106 has a rear 402, a front 404 and a strap 406. As described in more detail below, in one embodiment, the shoulder bag 106 is coupled to the first bag 104 together with the second bag 104 to form an assembly of the bag that can facilitate transportation, handling, (Not shown). Thus, for purposes of this disclosure, the shoulder bag 106 may be referred to as an upper bag or a third bag 106. [
In the embodiment of FIG. 4, the strap 406 is dimensioned to receive the handle 236 in a seated position. The strap 406 can slide down the handle 235 until the third bag 106 lies above the first bag 102 so that the strap 406 can then Thereby preventing the upper bag 106 from being detached. In other embodiments, bags of other types and / or sizes may be used as the third bag 106 (e.g., a laptop bag, a wallet, a carry-all bag, a gear bag). Typically, the third bag 106 may be sized to conform to aircraft requirements in the case of a portable bag. For example, the third bag 106 may be small enough to seat under a conventional aircraft seat. In another alternative embodiment, the third bag 106 may be removed.
5 to 8 show side views of the components shown in Figs. 2 to 4. Fig. 5 to 8 illustrate an embodiment of a method for forming travel bag assembly 100 (Fig. 1).
5 illustrates a first bag 102 and a second bag 104 arranged on the floor at respective upright positions, for example, after the traveler has retrieved the second bag 104 from the baggage carousel, Two hundred (104) and third (106) bags. The process for attaching the bags to each other to form an appropriate travel bag assembly 100 may begin when the bag is in this position. The traveler can then separate the handle 314 into two separate members.
6, the handle 314 may include a main handle strap 602 and a reinforcement handle strap 604. A sleeve including a snap or any other provisional connecting means may be used to hold the main handle strap 602 and the reinforcing handle strap 604 connected when the second bag 104 is used alone Lt; / RTI > Upon request, however, the traveler can separate the temporary connecting means so that the traveler can separate the reinforcing handle strap 604 from the main handle strap 602 as shown by arrow 606 in FIG.
The two ends of the main handle strap 602 are connected to the upper side of the second bag 104 at two points at or near the left and right sides of the upper side 306 of the bag 104 While the two ends of the reinforcing handle strap 604 are connected to the upper portion 322 (e.g., the upper third) of the rear of the second bag 104. For example, the two ends of the reinforcing handle strap 604 may be connected to two points at or near the upper edge of the rear 302. In one embodiment, the two attachment points for the reinforcing handle strap 604 are formed at approximately the same distance from the longitudinal center of the second bag 104, 236, such as the upright member 240 of FIG. Other embodiments may use other shapes of upright portions, handles and / or straps.
The traveler lifts the reinforcing handle strap 604 over the grip 238 of the handle 236 as shown by arrow 608 if the traveler removes the reinforcing handle strap 604 from the main handle strap 602. The extendable handle 236 may be retracted to facilitate this operation.
7, the traveler then slides the reinforcing handle strap 604 under the handle 236 and / or slides the reinforcing handle strap 604 under the handle 236 and / And extend the handle 236 upwardly through the strap 604. [ Accordingly, the reinforcing handle strap 604 and the handle 236 may be referred to and provided as an attachment member. Likewise, the reinforcing handle strap 604 may also be referred to as an attachment strap 604.
Figure 9 shows a top view of the shapes of the first bag 102 and the second bag 104 where the second bag 104 is attached to the first bag 102 but not the third bag 10 . As shown, when a traveler attaches the second bag 104 to the first bag 102 with the reinforcing handle strap 604, the reinforcing handle strap 604 is folded about three segments, i.e., around the handle 236, A first segment 604A extending from the two hundreds 104 and an intermediate second segment 604B extending from the third segment 604C and the handle 236, respectively. In one embodiment, the first segment 604A and the third segment 604C are approximately the same length 902 and the length 902 is approximately twice the length 904 of the segment spanning the handle 236 to be. For example, segments 604A and 604C may be approximately 10 inches long, and segment 604B may be approximately 6 inches long. The distance between the points of attachment on the second bag 104 to the segments 604A, 604C may be approximately 6 inches. The relatively wide intermediate segment in conjunction with the relatively wide attachment points on the second bag 104 prevents the left and right sides of the second bag 104 from being lifted away from the first bag 102, Thereby providing increased safety for the assembly 100. Other dimensions and / or ratios may be used in other embodiments. For example, the rigid handle 236 on the reading bag 102 may be less than or equal to 6 inches wide (e.g., a single post) and the attachment straps may be correspondingly longer or shorter. The durable suitcase assembly 100 thus extends from the trailing bag 104 around the handle 236 and from the trailing bag 104 to prevent the trailing bag 104 from sliding too far below the leading bag 102, 0.0 > 236 < / RTI >
7, the traveler may also slide the strap 406 under the handle 236 to position the third bag 106 on the reinforcing handle strap 604 and the first bag 102 The third bag 106 can be attached to the assembly 100. The added weight of the third bag 106 on the reinforcing handle strap 604 can provide improved stability for the travel bag assembly 100. [ The added weight of the third bag 106 may contribute to the overall stability of the suitcase assembly 100, depending on the weight and angle of the other bag. For example, if the trailing bag 104 is very heavy and the reading bag 102 is very lightweight, the third bag 106 on the top of the leading bag 102 will be positioned such that the first bag 102 is in an upright position It may provide a preferred force from the front to the underside of the wheel 242 of the first bag 102 to prevent it from returning.
In addition, as described above, a number of different kinds of objects can be used as the third bag 106. For example, a box or package may be positioned above the first bag 102 to be provided as a third bag 106, and the rollable travel bag assembly 100 may also be self- Can be provided as a compact load of stability. The third bag 106 may or may not include the strap 406.
When the handle 236 is stretched upward through the reinforcing handle strap 604, the assembly may have substantially the shape shown in Fig. 7, where one hundred (102) is in an upright position and the second bag (104) leans against the first bag (102). In this configuration, the majority of the weight of the second bag 104 can be mounted on the rear of the wheel 318. [ Thus, gravity can firmly pull the reinforcing handle strap 604 against the top of the first bag 102 and the front of the upstanding member 240. The reinforcing handle strap 604 is configured to maintain the second bag 104 in contact with at least a portion of the first bag 102 and the second bag 104 It is prevented from being moved away from the front of the first bag 102 or slid downward. In one embodiment, the reinforcing handle strap 604 maintains the upper rear side of the second bag 104 substantially adjacent to the upper rear side of the first bag 102. In another alternative embodiment, the second bag 104 may be further slid a short distance below the back of the first bag 102, depending on the attachment member. However, in order to provide weight distribution benefits, as is typically described below, it may be desirable to maintain (e.g., maintain) the top of the second bag 104 within a predetermined distance, such as approximately two inches above the first bag 102 May be preferred.
Referring again to Figure 8, the travel bag assembly 100 is shown in an oblique shape. Specifically, (a) the reinforcing handle strap 604 of the second bag 104 is wrapped around the handle 236 of the first bag 102, (b) the third bag 106 is wrapped around the reinforcement handle strap 604 (C) both the first bag 102 and the second bag 104 are arranged on the upper side of the wheels 242 And at least a portion of the rear of the second bag 104 is at least partially offset from the front of the first bag 102 by a predetermined angle, / RTI > In an embodiment that does not include the third bag 106, the assembly 100 may be fully assembled when there is no third bag 106, although it is the shape described above.
The reinforcing handle strap 604 is dimensioned to engage the handle 236 when the second bag 104 is aligned with the first bag 102. [ The reinforcing handle strap 604 is typically flexible but substantially inelastic, and the strap 604 may also have some elasticity. Thus, when the first bag 102 is tilted forward from the upright position to the tilted position shown in FIG. 8, the reinforcing handle strap 604 is positioned between the first bag 102 102 of the first bag 102 or slide the second bag 104 downwardly forward of the first bag 102. [ For example, the relative positions of the second bag 104 and the tops of the first bags 102 are less than 5% (e.g., 1 inch) of the height of the first bag 102 in the embodiment of FIG. 8 It can change. In other embodiments, depending on the size and weight of the trailing bag 104, the attachment means 604 may be provided for larger or smaller changes in position to maintain balance.
When the first bag 102 and the second bag 104 are tilted or tilted as shown in Fig. 8, most of the weight of the second bag 104 lies in front of the wheel 318. Fig. Thus, the weight of the second bag 104 keeps the second bag 104 firmly compressed with respect to the first bag 102, and prevents the second bag 104 from accidentally returning to its upright position do. In addition, typically a sufficient portion of the weight of the assembly 100 is loaded in front of the wheel 242 to prevent the first bag 102 from returning to its upright position. As will be described in more detail below, this tendency of the bag to remain in a tilted or forwardly fixed position may be referred to as internal pitch stability or self-stabilizing.
In one embodiment, the contact area where the front 222 of the first bag 102 contacts the rear 302 of the second bag 104 is 75% of the front 224 of the first bag 102, Covers more than 60% of the rear 302 of the two bags 104. Depending on the contact area, the second bag 104 helps to move relative to the first bag 102.
Thus, the bag 102, 104 is substantially fully loaded and is configured in the position shown in FIG. 8, wherein the travel bag assembly 100 includes a part of the weight of the assembly supported by the wheel 242 and the weight of the wheel 318 But tend to remain in this position depending on the rest of the support. Thus, when the assembly is complete, the traveler does not need to make any effort to keep the assembly together and properly position it. The traveler can also easily move the assembly 100 with one hand. In addition, when suspended or moving, tilted or otherwise, the assembly 100 can be fully self-stabilizing and its prescribed course can be maintained without a hand or other external support.
Further, in some embodiments, a significant weight of the assembly 100 may be loaded in front of the wheel 242 when completed and ready to be rolled as shown in FIG. For example, depending on the distribution of weight within each bag and the weight of each bag, approximately 20-40% of the weight of assembly 100 may be loaded in front of wheel 242 of first bag 102 .
In addition, the handle 236 provides a substantial leverage and the reinforcing handle strap 604 prevents the second bag 104 from moving from its position on the first bag 102. Thus, it is typically easy to press the handle 236 and fully lift the wheel 318 from the ground. For example, if the weight is well distributed within the bag, a 100 pound traveler can easily manipulate the travel bag assembly 100 over 100 pounds with one hand. In addition, as the traveler further pushes the handle 236, the greater weight is moved forward of the wheel 242. [ Thus, the traveler can easily maintain balance of the entire assembly 100 on the wheel 242, similar to steering the stroller on stairs, escalators, Thus, as the assembly 100 is balanced against the wheels 242 of the reading bag 102, the traveler may have a variety of different ways of handling two or more parts of a conventional suitcase with each hand The entire assembly 100 can be more easily manipulated on the upward and downward escalators through other obstacles and around the corners, on the stairs. Moreover, since the assembly 100 is not wider than the widest bag in the assembly 100, the assembly 100 can be more easily manipulated through complicated or narrow doors or roads.
When the traveler does not want to move the assembly 100, the traveler can easily return the first bag 102 to the upright position so that the foot 244 can support a portion of the weight of the assembly 100, Contact.
Also, as described above, when the reinforcing handle strap 604 connects the first and second bags to each other, the left and right sides of the second bag 104 are positioned in the first Which helps lift or move away from the bag 102. That is, the reinforcing handle strap 604 prevents the second bag 104 from spinning or rotating about its longitudinal axis with respect to the first bag 102. 8, the reinforcing handle strap 604 is configured such that when the first bag 102 and the second bag 104 are substantially fully packed, the second bag 104 is positioned between the first bag 102 Lt; RTI ID = 0.0 > 5 < / RTI > According to another embodiment, the first bag may be rolled up to 30 degrees with respect to the first bag. This type of stability to assembly 100 can be referred to as internal roll stability. In contrast, the resistance of the entire assembly 100 to rotation about its central axis can be determined primarily by the distance between the wheels on the underside of the first bag 102, May be referred to as external roll stability.
The assembly 100 may also exhibit excellent internal and external pitch stability. For purposes of this disclosure, internal pitch stability refers to the tendency of both bags 102 and 104 to have the same tilt angle relative to each other when the first and second bags 102 and 104 are of a durable shape. That is, the attachment member, weight distribution, and other features may not even be gripped by a traveler even when the traveler does not grip the handle 236 or any other portion of the first bag 102 or the second bag 104 And to withstand forces that can be leaned up or down against other bags. The excellent internal pitch stability is one of the contributors to the easy lifting of the wheel 318 by pushing the handle 236. External pitch stability refers to the tendency of the complete assembly 100 to retain all four wheels 242, 318 on the ground.
In addition, the assembly 100 exhibits excellent internal and external yaw stability. For purposes of disclosure, internal yaw stability refers to the tendency of the first and second bags 102, 104 to maintain the same relative alignment with respect to their longitudinal axis. That is, considering the contact patch 802 between the first bag 102 and the second bag 104, the front 304 of the second bag 104 is located at the rear of the first bag 102 222 in the direction of rotation. External yaw stability refers to the tendency of the assembly 100 to move in a straight line when all four wheels are rolled. The characteristics of pitch, roll and fatigue stability exhibited by the assembly 100 contribute to the self-stabilization of the assembly 100 when the bags 102, 104 are tilted or otherwise, when in motion and stationary. The components of the assembly 100 may include one or more velcro straps, straps including snaps or zippers, alternative attachment means such as straps on the trailing bag 104 that are detached and reconnected to the corresponding straps in the reading bag 102 . The strap may be provided as a reinforcing strap when not used to form the suitcase assembly 100 and may or may not be adjusted to provide a suitable balance / grip ratio for the bag to be packaged at different weights.
10 illustrates a front view of another embodiment of a rolling duffle bag 1050 and a back view of another embodiment of the portable bag 1040. As shown in Fig. The portable bag 1040 may also be referred to as a first bag 1040 or a reading bag. Rolling duffle bag 1050 may also be referred to as a trailing bag or second bag 1050. As shown, a mating strap 1042 is attached to the front of the first bag 1040 and a corresponding mating hook 1052 is attached to the rear of the second bag 1050. [ The matching strap 1042 can be made of fabric, leather, plastic or any other suitable material. The mating hooks 1052 may be made of metal, plastic or any other suitable material.
The mating strap 1042 is dimensioned to receive the mating hook 1052. For example, the upper side 1054 of the matching hook 1052 may be formed with a width of approximately 4 inches, and the rear side of the first bag 1040 may be substantially the same width as the upper side 1054. In engagement with the mating strap 1042, a relatively wide matching hook 1052 tends to prevent the left and right sides of the second bag 1050 from being lifted or lifted away from the first bag 1040 This can be. The opening 1044 may be referred to as a mating slot 1044. Other dimensions may be used in other embodiments.
Figure 11 shows a side view of bags 1040 and 1050 in a first position. To initiate connection of the first bag 1040 and the second bag 1050 into the secure travel bag assembly 1000 (Figures 12 and 13) or the luggage train, The first bag 1040 and the second bag 1050 can be inclined a little toward the rear. The traveler can then insert a tip 1056 of the mating hook 1052 into the mating slot 104 $.
12 shows a side view of the upright bags 1040 and 1050 in the travel bag assembly 1000. FIG. As shown, when the first bag 1040 and the second bag 1050 are returned to the upright position, the mating hooks 1052 can hold the bags together. Thus, the mating hook 1052 and the mating strap 1042 can be referred to as attachment members.
Figure 13 shows a side view of the bags 1040 and 1050 in an inclined state within the travel bag assembly 1000. As the first bag 1040 is tilted away from the second bag 1050, the mating hook 1052 is pushed into the mating slot 1052 until the inner upper side 1054 of the mating hook 1052 is engaged with the mating strap 1042 1044, respectively. At an oblique orientation, at least a portion of the weight of the second bag 1050 may be mounted in front of the wheel 1058 of the second bag 1050, so that gravity is directed toward the front of the first bag 1040, And compresses the back of bag 1050. Thus, similar to the embodiment of Figure 8, the suitcase assembly 1000 can be self-stabilizing in this shape and can be easily rolled with one hand. Also, the handle of the first bag 1040 can be used to lift the wheel 1058 from the ground, thereby allowing excellent operability substantially as described above with respect to Figs. 2-9.
14-17 illustrate a side view of another embodiment of a rolling bag 1402 and rolling duffle bag 1404 according to various steps of yet another method for forming a luggage assembly 1400. [ In the illustrated embodiment, the portable bag 1402 and the rolling duffle bag 1404 include two or more respective sets of straps 1406 and 1410, and the removable connectors 1408 and 1412 include straps 1406 and 1410 ). ≪ / RTI > The connectors 1408 and 1412 are configured to separate and recombine with the receiving connector portion on the same bag or adjacent bag. That is, one end of the straps 1406 and 1410 is attached to the upper rear of the bags 1402 and 1404, and the middle ends of the straps 1406 and 1410 form a portion and an end of the connectors 1408 and 1412, respectively. Another end of the straps 1406 and 1410 is attached to the front upper side of the bags 1402 and 1404 and another middle end of the straps 1406 and 1410 is connected to another portion of the connectors 1408 and 1412 . The straps 1406 and 1410 may span from the front to the rear over the upper side of each bag 1402 and 1404 when a portion of the connectors 1408 and 1412 is engaged. In addition, a portion of the connector 1412 on the duffle bag 1404 may be coupled to a suitable portion of the connector 1408 on the portable bag 1402 and backwards. Straps 1406 and 1410 and connectors 1408 and 1412 may also be collectively referred to herein as attachment members.
Figure 15 shows discrete connectors 1408 and 1412 where the four middle ends of the straps 1406 and 1410 are kept loose. 16, a portion of the connector 1412 on the strap 1410 attached to the upper rear side of the duffel bag 1404 is connected to a portion of the connector 1408 on the strap 1406 attached to the upper rear side of the portable bag 1402 . The length of the straps 1406 and 1410 can be adjusted to pull the portable bag 1402 and the duffle bag 1404 more closely when the connectors 1408 and 1412 are engaged.
17 shows a side view of the travel bag assembly 1400 with the bags 1402 and 1404 in a tilted position. As the connectors 1408 and 1412 are engaged, the bag 1404 is leaned in the direction of the bag 1402 because the bag 1402 is inclined. With this orientation, at least a portion of the weight of the bag 1404 may be mounted on the front and / or top of the wheel 1414 of the bag 1402 so that gravity is transmitted to the bag 1404 against the front of the bag 1402, As shown in Fig. Thus, similar to the embodiment of FIG. 8, the suitcase assembly 1400 can be self-stabilized in this shape and can be easily rolled with one hand. In addition, the handle of the first bag 1402 can be used to lift the wheel 1416 from the ground, thereby allowing excellent operability substantially as described above with respect to Figs. 2-9.
Figures 19 and 20 illustrate exemplary travel bag assemblies 1900 including a carry-on suitcase 1902 connected to a trailing suitcase 1904 and a shoulder bag 1906 Fig. In addition, the suitcases 1902 and 1904 are connected to a stabilizer 1908 such that the weight of all or most of the assemblies 1900 is mounted on the wheels of the portable suitcase 1902 and the trailing suitcase 1904 . According to the stabilizer 1908, the assembly 1900 can be self-stabilizing when it is in motion and stopped,
In particular, the traveler may use the handle 1910 to elevate the assembly 1900 as shown in FIG. 20 or to maintain the assembly 1900 in an inclined position, as shown in FIG. 19, It is not necessary to grasp it. These and other features of the suitcase assembly 1900 are provided for excellent stability and operability. Additional details about components and steps used for various operational features of the travel bag assembly 1900 and stabilizer 1908 as well as forming the rollable travel bag assembly 1900 are provided below.
19A and 21A, FIG. 21A illustrates an embodiment of a stabilizer 1908 including a first connector or attachment member 2102 configured to fit under a handle 1912 on a first suitcase. The handle 1912 is typically sized to fit the hand of a person and the attachment member 2102 is configured to increase the stability of the suitcase 1904 upon engagement with the suitcase 1902 with the stabilizer 1908 May be further configured to be at least half of the length of handle 1912. Stabilizer 1908 also includes an elongate portion 2104 (also referred to as a center body) coupled to attachment member 2102.

Fig. As shown, the suitcase suitcase 1902 has a front 2502, a rear 2504, an upper 2506, a lower 2508, a left 2510 and a right 2512. As described in more detail below, in some embodiments, two or more suitcases 1902, 1904 (Figure 19) form a travel bag assembly 1900 that facilitates transport, handling, and drafting Gt; 1908 < / RTI > Thus, for the purpose of this disclosure, suitcases 1902 and 1904 may be referred to as parts of suitcases or suitcases.
In the embodiment of FIG. 25, the upper side of the suitcase 1902 includes a soft handle 1916. The left side 2510 may also include a soft handle. The first suitcase 1902 also includes two elongatable rigid upright members 1914 and a substantially rigid elongate grip member 2520 that spans over the upright members 1914. The substantially rigid, And a handle 1910. In the embodiment of Fig. 19, the handle 1910 is located at the rear of the suitcase 1902, and is centered in the longitudinal direction between the left and right sides. In another alternative embodiment, the handle 1910 is attached to a single rigid infeedable upright member 1914 in place of the two inflatable upright members 1914.
The suitcase 1902 may also have a pair of rigid or swivel wheels 1920 with one wheel positioned at the rear left corner of the lower side of the suitcase 1902, 1902 located at the rear right corner of the lower side. One or more foots 2524 may be used to provide stability when the suitcase 1902 is placed in an upright position relative to the weight loaded on the foot 2524 and the wheel 1920 and to prevent movement of the suitcase 1902 May be provided at or near the lower frontal side. Alternatively, a swivel wheel may be provided behind and in front of the suitcase.
To maintain balance of the suitcase assembly 1900, the suitcase 1904 typically has the same size, greater than, and / or the same weight as the suitcase 1902. The stabilizer 1908 may be adjusted when it is necessary to maintain the balance of the suitcase assembly 1900 in an upright and tilted position with the wheels 1918 and 1920 of the suitcases 1902 and 1904 on the ground . If the stabilizer 1908 is too tight, the wheels 1920 of the suitcase 1904 may be lifted from the ground, thereby causing the suitcase assembly 1900 to become unstable. If the stabilizer 1908 is too loose, it may be difficult to balance the suitcases 1902 and 1904 so that the suitcase assembly 1900 is self-stabilizing. The stabilizer 1908 provides a wide range of adjustments to form a center of gravity for various sizes and weights of the suitcase that maintains balance of these suitcases in an inclined and upright position.
Figs. 26-29 illustrate an embodiment of a method for forming travel bag assembly 1900 (Fig. 19) and side views of travel bag portions 1902, 1904. Instructions in accordance with an embodiment of a method for forming the suitcase assembly 1900 may include an indication of the location where the stabilizer 1908 is sold and / or an indication of the location of the manufacturer < RTI ID = 0.0 > May be obtained by other sources, such as a web site, or may be included in a package containing the stabilizer 1908. [
26 illustrates a first suitcase 1902 that is arranged in an upright position on the floor at each upright position that can be positioned, for example, after a traveler has retrieved the second suitcase 1904 from a baggage carousel And a second suitcase 1904 are shown. The process for attaching the suitcases to each other to form a stable travel bag assembly 1900 can be started when the suitcases 1902 and 1904 are in this position. The rear of the suitcase 1904 is positioned adjacent to the front of the suitcase 1902. One of the slots 2108 of the stabilizer 1908 (FIG. 21A) is disposed above the retractable handle 1910 of the suitcase 1902.
Figure 27 shows the loose end 2106 (Figure 21A) of the stabilizer 1908 ready to be pulled through under the handle 1912 on the suitcase 1904 and thus the upper side of the suitcase 1904 And is engaged with the handle 1912. Figure 28 shows the stabilizer 1908 pulled tightly through the handle 1912 and Figure 29 shows the stabilizer 1908 folded over the handle 1912 so that the end 1902 of the attachment member 2102 2106) (Fig. 21A) can be engaged with the edge of one of the slots 2108. Fig.
In another alternative embodiment, the traveler may engage the handle 1910 at one end 2106 (FIG. 24) of the stabilizer 2300 (FIG. 24) and above the first portion of the suitcase 1904 The other end 2306 of the stabilizer 2300 and the upper portion of the second portion of the suitcase 1902. In this way,
The first suitcase 1902 may be in the upright position when one of the slots 2108 engages the handle 1910 or when the handle 1916 is engaged with the attachment member 2302 And the second suitcase case 1904 can be leaned against the first suitcase case 1902. In this configuration, most of the weight of the second suitcase case 1904 can be mounted on the rear side of the wheel 1920. Thus, gravity can pull the stabilizers 1908 and 2300 firmly against the handles 1912 and 1910 or 1916.
The stabilizers 1908 and 2300 are configured to maintain the second suitcase case 1904 in contact with at least a portion of the first suitcase case 1902 and the travel case assembly 1900 is configured to hold the second suitcase case 1904, (1904) is moved away from the front of the first suitcase (1902) or slid downward. In some embodiments, the stabilizers 1908 and 2300 maintain the upper rear side of the second suitcase case 1904 substantially adjacent to the upper rear side of the first suitcase case 1902. The second suitcase case 1904 may be further slid a short distance below the rear of the first suitcase case 1902 in accordance with the stabilizers 1908 and 2300. In other embodiments, However, in order to provide the benefits of weight distribution, as described below, typically within a predetermined distance, such as approximately 2 to 4 inches above the first suitcase 1902, It may be preferable to keep the upper side.
When the first suitcase case 1902 and the second suitcase case 1904 are inclined or inclined as shown in Fig. 19, most of the weight of the second suitcase case 1904 is loaded behind the wheel 1920. Fig. The weight of the second suitcase case 1904 maintains the second suitcase case 1904 firmly compressed with respect to the first suitcase case 1902 and the second suitcase case 1904 does not assume the upright position Thereby preventing it from returning. In addition, typically, a sufficient portion of the weight of assembly 1900 is loaded in the rear of wheel 1920 to prevent the first suitcase case 1902 from returning to its upright position. As will be described in more detail below, this tendency of the suitcase to tilt or stay in a fixed position toward the front may be referred to as internal pitch stability or self-stabilizing have.
19, the travel bag assembly 1900 includes a part of the weight of the assembly supported by the wheels 1918 on the suitcase 1902, And the rest supported by the wheel 1920 on the suitcase 1904. Thus, when the assembly 1900 is completed, the traveler does not need to make any effort to keep the assembly together and properly position it. The traveler can also easily move the assembly 1900 with one hand. In addition, when suspended or in motion, tilted or otherwise, assembly 1900 can be fully self-stabilizing and can maintain its course without movement by hand or any other external support when in motion.
Further, in some embodiments, a significant weight of the assembly 1900 may be mounted to the rear of the wheel 1920 in the completed and ready to roll position shown in FIG. For example, depending on the weight of each suitcase and the weight distribution of each suitcase, approximately 20% to 40% of the weight of the assembly 1900 is deposited on the rear of the wheel 1920 of the suitcase 1904, .
In addition, the handle 1910 provides a substantial leverage, and the stabilizers 1908 and 2300 prevent the second suitcase case 1904 from being moved out of its position on the first suitcase case 1902. Thus, it is typically easy to press the handle 1910 and lift the wheel 1920 completely out of the ground. For example, if the weight is properly distributed within the suitcase, a 1910 pound traveler can easily manipulate the suitcase assembly 1900 with more than 1900 pounds in one hand. In addition, as the traveler further depresses the handle 1910, a larger weight is moved behind the wheel 1920. Thus, the traveler can easily balance the entire assembly 1900 on the wheel 1918, similar to steering the stroller on stairs, escalators, and the like. Thus, as the assembly 1900 is balanced against the wheel 1918 of the leading suitcase 1902, the traveler may be more difficult to handle two or more portions of the conventional suitcase with each hand The entire assembly 1900 can be more easily manipulated on the upward and downward escalators through various other obstacles and around the corners, on the stairs. In addition, assembly 1900 can be more easily manipulated through complicated or narrow doors or roads, since assembly 1900 is not wider than the widest suitcase in assembly 1900. Alternatively, when the suitcases 1902 and 1904 include swivel wheels, a downward pressure may not be required to steer the suitcase assembly 1900 within a confined space.
When the traveler does not want to move the assembly 1900, the traveler can easily return the first suitcase 1902 to the upright position so that the foot 2524 can support a portion of the weight of the assembly 1900, / RTI >
Further, according to the manner in which the stabilizers 1908 and 2300 connect the first suitcase and the second suitcase to each other as described above, when the assembly 1900 is in a durable shape, And the right side are lifted from the first suitcase case 1902 or moved away therefrom. That is, the stabilizers 1908 and 2300 prevent the second suitcase case 1904 from spinning or rotating relative to the first suitcase case 1902 along its longitudinal axis. 26, the stabilizers 1908 and 2300 may include a second suitcase case 1904 when the first suitcase case 1902 and the second suitcase case 1904 are substantially completely packed. In this case, Thereby preventing the first suitcase 1902 from rolling in excess of 5 degrees. According to another embodiment, the first suitcase can be rolled up to 30 degrees with respect to the first suitcase. This type of stability to assembly 1900 can be referred to as internal roll stability. In contrast, the resistance of the entire assembly 1900 to rotation about its central axis can be determined primarily by the distance between the wheels on the underside of the first suitcase 1902, May be referred to as an external roll stability.
The assembly 1900 can also exhibit excellent internal and external pitch stability. For purposes of this disclosure, the internal pitch stability refers to the tendency of both of the suitcases 1902, 1904 to have the same inclination angle relative to each other when the first and second suitcases 1902, 1904 are of a durable shape. That is, the attachment member, weight distribution, and other features may not even be visible when the traveler does not grip the handle 1910 or any other portion of the first suitcase 1902 or the second suitcase 1904 To resist the force that can be leaned up or down with respect to the other suitcase. The excellent internal pitch stability is one of those contributing to the easy lifting of the wheel 1920 by depressing the handle 1910. External pitch stability refers to the tendency of the complete assembly 1900 to remain on the ground with wheels 1918 and 1920.
In addition, assembly 1900 exhibits excellent internal and external yaw stability. For purposes of disclosure, internal yaw stability refers to the tendency of the first and second suitcases 1902, 1904 to maintain the same relative alignment with respect to their longitudinal axis. That is, when considering the contact between the first and second suitcases 1902 and 1904, the rear of the second suitcases 1904 tends not to rotate about the front 2502 of the first suitcases 1902 . External yaw stability refers to the tendency of the assembly 1900 to move in a straight line when all four wheels are rolled. The characteristics of pitch, roll, and stiffness stability exhibited by assembly 1900 contribute to self-stabilization of assembly 1900 when the suitcase 1902, 1904 is tilted or otherwise, when moving and stationary .
Referring to Fig. 30, another embodiment of the stabilizer 3002 formed in the pocket 2004 at the upper side of the suitcase 1902 is shown. One end of the stabilizer 3002 may be sewn or otherwise otherwise fastened into the pocket 3004 and the other end 3006 may be coupled to another suitcase (not shown). The stabilizer 3002 may be stored in the pocket 3004 when not in use. The stabilizer 3002 may be completely removed from the pocket 3004 and one end (not shown) of the stabilizer 3002 may be attached to the handle 1910,1916 or the suitcase 1902, And the other end 3006 of the stabilizer 3002 is attached to a suitable position on another suitcase (not shown).
