Description

The present invention relates to bag systems, specifically to bag systems for securely coupling bags together.
In the related art, it has been known to combine supplemental bags with main bags to carry additional items. Purses are used to carry a variety of personal effects Such as keys, identification cards, credit cards, cash, cell phones, eyewear, medications and makeup. The entire contents of the purse are considered essential to a person's daily life, though the type of purse or bag one carries throughout the day will often vary.
Purses are used as a fashion accessory and are often selected to coordinate with an outfit or occasion. Purses can be selected based on their utility or appropriateness such as a purse chosen for a casual outdoor activity versus a formal occasion. When switching from one purse or bag to another, the user is required to transfer each, individual item to the next desired style. This process is time consuming, burdensome and may not result in the same organization of contents, making the search for a given item a constant challenge. The transfer process may also result in some items being left behind or lost.
In addition, persons often need to carry or transport additional items that may not fit in a main bag. More, persons may have a desire to keep items separate as it is difficult to access specific items when such items are stored together in a single large compartment. As a result, persons are forced to carry additional bags or use other cumbersome solutions to transport additional items.
Bags of bag systems may be coupled together for transporting items. A number of separate pieces may be used separately and carried separately, or a number of separated pieces may be secured together so as to function as a unitary structure. While the separate pieces are capable of functioning independently of one another, they may be secured together while traveling to make the handling of the bags more manageable. For instance, bags may be coupled together through a variety of coupling mechanisms, such as: straps, zippers, hooks, snaps, belts, buckles, hook and loop, and so on.
Some improvements have been made in the field. Examples of references related to the present invention are described below in their own words, and the supporting teachings of each reference are incorporated by reference herein:

U.S. Patent No.: 2,989,998, issued to Harris , discloses in combination, a bag and an auxiliary container mounted on said bag, said bag having opposed flat side walls providing an opening along the top edge of said bag, a closing flap secured to one of said side walls and extending over said opening, and latch means on the other side wall for engaging said closing flap, said auxiliary container having opposed flat side walls providing an opening along one edge thereof and closure means for said opening, and means for detachably connecting said container to said bag with one side wall of said container in close contact throughout the extent thereof with said one side Wall of the bag, said connecting means comprising a pair of laterally spaced latch means projecting outwardly from said one side wall of the bag adjacent the top edge thereof and a pair of laterally spaced openings in said one side wall of the container for receiving the respective latch means, whereby said container is held in depending and closely abutting relation to said bag and the closure means on the container may be opened to gain access to said pair of spaced latch means for manipulation thereof to detach the container from said bag while leaving said bag in a closed condition.
U.S. Patent No.: 3,696,850, issued to Rosenblum , discloses an item of luggage to be hand-carried when travelling, especially on airplanes, buses, trains or other public conveyances to enable the articles contained in the luggage to be immediately available and to eliminate the possibility of luggage becoming lost in transit. The luggage includes a larger bag having an access opening therein and a carrying strap detachably connected thereto, a smaller bag detachably mounted on one side of the larger bag for support therefrom when assembled therewith and a detachable tray-like container of substantially rigid construction mounted on and forming a continuation of the bottom of the larger bag. The detachable carrying strap for the larger bag is removed therefrom and attached to the smaller bag when it is desirable to carry only the smaller bag.
U.S. Patent No.: 4,081,061, issued to Tucker , discloses a plurality of independent luggage pieces capable of functioning independently of one another and each having fastening means independent of their closures for securing the separate pieces together as a unitary structure as desired while being stored or in use.
U.S. Patent No.: 6,213,266, issued to Hollingsworth , discloses a modular luggage system includes wheeled flight bag with an externally demountable releasably attachable computer carrying case for carrying a delicate instrument such as a portable computer. The wheeled flight bag has wheels on a bottom wall and a retractable handle incorporated in an integral frame running up a back wall. The front of the flight bag includes a projecting member or salient tongue spaced a selected distance from a releasable fastening member. A computer carrying case adapted to be externally dismountable from the flight bag has a bottom wall and a back wall including a receiving slot or aperture for receiving the salient tongue mounted on the flight bag. The computer carrying case also includes a releasable fastening member spaced such that when the computer carrying bag is mounted upon the flight bag, the salient tongue is received in the receiving aperture and the computer carrying case fastening member locks, buckles or otherwise fastens with the cooperating fastening member mounted on the top surface of the flight bag. Preferably, the computer carrying case includes a carrying handle spaced apart from the back edge of the top wall. In use, one may grasp the computer carrying case handle with the right hand and, with the thumb, depress a button or otherwise actuate the releasable fastening member, thereby releasing the fastening members from one another, such that the computer carrying case may be lifted and withdrawn away from the flight bag. The computer carrying case preferably includes a shock absorbing suspension or impact absorbing cushions for providing protection to the delicate instrument enclosed within.
U.S. Patent Application Publication No.: 2008/0011567, by Hammond , discloses an improved storage bag has a retaining member disposed on an inside surface of a first side wall of a main bag. The retaining member allows supplemental bag to hang on an outside wall of the main bag. An existing storage bag can have a bracket configured to extend partially along an inside portion of a side wall of the briefcase. The bracket has a hook-portion to extend out of the top of the briefcase and partially along the outside portion of the side wall of the briefcase and a retaining member. This configuration also allows a supplemental bag to be attached to the retaining member to hang along an outside wall of the bag.

The document GB840343A discloses a bag having a self-contained supplementary case which is detachably secured externally to one of the side walls of the bag.
The inventions heretofore known suffer from a number of disadvantages which include: being difficult to manufacture, being difficult to assemble, being difficult to access stored items, not coupling efficiently, requiring the use of additional straps, having an easily accessible coupling mechanism, being difficult to detach, not having a secure coupling mechanism, and not protecting additional items.
What is needed is a bag system that solves one or more of the problems described herein and/or one or more problems that may come to the attention of one skilled in the art upon becoming familiar with this specification.

DETAILED DESCRIPTION OF THE INVENTION

For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the exemplary embodiments illustrated in the drawing(s), and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended.
Figure 1 is a front perspective view of a bag system, showing a main bag removably coupled to a supplemental bag, according to one embodiment of the invention. There is shown a bag system 10 including a main bag 11. The main bag 11 has a front side of main bag 12. Coupled to the front side of main bag 12 is a supplemental bag 14.
As shown, the bag system 10 includes a main bag 11 and a supplemental bag 14. The main bag 11 and the supplemental bag 14 are configured to carry, house, protect, transport, etc. personal items. Accordingly, the main bag 11 and the supplemental bag 14 may be purses. The main bag 11 is shown to be larger than the supplemental bag 14; however, the main bag 11 may be smaller than, or identical to, the supplemental bag 14. The main bag 11 and the supplemental bag 14 may be comprised of a variety of materials, such as, but not limited to: leather, plastic, metal, cotton, and polyester. The main bag 11 and the supplemental bag 14 may have straps.
The supplemental bag 14 is removably coupled to the main bag 11 at the front side of main bag 12. The supplemental bag 14 may be secured to the front side 12 through a variety of couplings, such as, but not limited to: snaps, buckles, hook and loop, locks and ties. The supplemental bag 14 may be secured to the front side 12 so that it is not easily uncoupled from the main bag 11.
In operation, items are stored within the main bag 11. Items are also stored within the supplemental bag 14. The supplemental bag 14 is securely removably coupled to the main bag 11. The supplemental bag 14 is transported with the main bag 11. The supplemental bag 14 is removed from the main bag 11 with effort. The supplemental bag 14 may be uncoupled from the main bag 11 by a two-button (or other actuator type) latch assembly disposed within an interior the main bag 11 and extending through a slit in the body of the main bag, spaced from the mouth thereof. Accordingly, the supplemental bag 14 may only be uncoupled from the main bag 11 by accessing an interior of the main bag 11 through the mouth of the main bag.
Advantageously, a user of a such a bag need not be worried about someone surreptitiously removing the supplemental bag from the main bag so long as the mouth of the main bag is secure and/or under observation. Further, the slit through the main bag provides air circulation within the main bag even when the mouth is zipped closed. Additionally, wherein the latch assembly requires actuation of two buttons (or other actuator-type) to release the supplemental bag from the main bag, the user need not worry about items within the main bag accidentally releasing the supplemental bag from the main bag.
Figure 2 is a side view of a bag system, showing a main bag removably coupled to a supplemental bag by a connector, according to one embodiment of the invention. There is shown a bag system 10 including a main bag 11. The main bag 11 is removably coupled to a supplemental bag 14 by a connector 20. The connector 20 is coupled to the supplemental bag 14 and disposed between the main bag 11 and the supplemental bag 14.
As shown, the supplemental bag 14 includes a connector 20. The connector is coupled to the supplemental bag 14 and extends outwardly therefrom toward the main bag 11. The connector 20 connects the supplemental bag 14 to the main bag 11. Accordingly, the connector 20 is disposed between the supplemental bag 14 and the main bag 11. The connector 20 may be a variety of connectors for coupling the supplemental bag 14 to the main bag, such as, but not limited to: belts, straps, ties, buckles, pinch latches, and push button latches. The connector 20 may be a pinch latch, such as, but not limited to, a Southco 60 Squeeze-Release Latch, by Southco, located at 210 N. Brinton Lake Road, Concordville, PA 19331. The connector may be a push button release buckle, such as, but not limited to, an Metal 5/8 Inch Side Release Buckle, by Paracord Planet, located at 1320 5^th Ave. N., Fargo, ND 58102. The connector may be/include a latch assembly as described in US Patent Application No. 16/455,487 . Accordingly, the connector 20 may be entirely comprised of rigid materials, such as, but not limited to: metal, plastic, and metal alloys.
Figure 3 is a sectional view of an interior surface of a front side of main bag, according to one embodiment of the invention. There is shown a main bag 11 with a front side of main bag 12. Coupled to the front side of main bag 12 along an interior surface 32 is a buckle 30. A slit 31 is disposed above the buckle 30. The main bag 11 also has a mouth of main bag 33 and a bottom of main bag 34.
As shown, the front side of main bag 12 includes an interior surface 32. A buckle 30 is disposed along, and coupled to, the interior surface 32. A slit 31 is disposed along the interior surface 32 above the buckle 30. The slit 31 may allow the connector (See e.g., Figure 2, Item 20) to enter the front side 12 into the main bag 11 and couple to the buckle 30. Accordingly, the slit 31 may be shaped and/or sized to permit the connector (See e.g., Figure 2, Item 20) to enter the main bag 11 and couple to the buckle 30. The buckle 30 may only be accessed from within the main bag 11. As a result, when coupled to the buckle 30, the connector (See e.g., Figure 2, Item 20) may only be uncoupled from the buckle 30 from within the main bag 11.
In one non-limiting embodiment, the slit 31 is disposed through a middle region of the main bag 11 that is substantially equidistant from the mouth of main bag 33 and the bottom of main bag 34, such that the middle region is orthogonal to a plane of the mouth 33 and a plane of the bottom 34 of the main bag 11. Accordingly, the slit 31 located a distance from the mouth of main bag 33 substantially equal to a distance from the bottom of main bag 34, and is thereby central to the mouth of main bag 33 and the bottom of main bag 34. The slit 31 is disposed along the interior surface 32 above the buckle 30, and between the buckle 30 and the mouth of main bag 33. However, in another non-limiting embodiment, the buckle 30 may be disposed above the slit 31. There may be additional slits disposed in other regions of the main bag. Further, there may be accessories that attach to an interior of the bag and do not pass through any slit.
Figure 4 is a sectional view of the interior surface of Figure 3, showing the buckle, according to one embodiment of the invention. There is shown a main bag 11 with an interior surface 32. Coupled to the interior surface 32, and disposed opposite the interior surface 32 of the front side 12, is a buckle 30. Also, disposed through the interior surface 32 is a slit 31. The main bag 11 additionally includes a mouth of main bag 33 and a bottom of main bag 34.
As shown, the main bag 11 includes a buckle 30. The buckle 30 is coupled to the main bag 11. Coupling structures are not shown; however, the buckle 30 may be coupled to the main bag 11 through a variety of couplings, such as, but not limited to: adhesives, rivets, screws, bolts, pins, clips, and snaps. The buckle 30 is disposed below the slit 31. The slit 31 provides an opening in the main bag 11 for a connector (See e.g., Figure 2, Item 20) to pass through slit 31 and into the buckle 30 for removably coupling a supplemental bag (See e.g., Figure 1, Item 14) to the main bag 11.
Figure 5 is a back perspective view of a supplemental bag, showing a connector according to one embodiment of the invention. There is shown a supplemental bag 14. A connector 50 is coupled to a back side of supplemental bag 51. The connector 50 includes a second member 53, and a third member 54 coupled to the second member 53.
As shown, the connector 50 includes a second member 53 coupled to the back side 51 and extending outwardly therefrom, orthogonal to the back side 51. A third member 54 is coupled to the second member 53 and extends outwardly from the second member, orthogonal to the second member 53 and planar to the back side. Accordingly, the third member 54 of the connector 50 extends to function as a tongue by projecting through a slit (See e.g., Figure 3, Item 31) and into a buckle (See e.g., Figure 3, Item 30) of a main bag (See e.g., Figure 3, Item 11). The third member 54 of the connector 50 may enter a slit (See e.g., Figure 3, Item 31) and removably couple to a buckle (See e.g., Figure 3, Item 30) of a main bag (See e.g., Figure 3, Item 11). The illustrated third member 54 is T-shaped.
Figure 6 is a side perspective view of a connector, showing a connector tongue, according to one embodiment of the invention. There is shown a connector 50. The connector 50 includes a connector tongue 60.
As shown, the connector 50 includes a connector tongue 60. As shown, the connector 50 is U-shaped. The connector tongue 60 is T-shaped. The connector 50, including connector tongue 60, may be rigid and may not bend or give when force is applied. The connector 50, including connector tongue 60, may be comprised of metal.
Figure 7 is a side sectional view of the supplemental bag of Figure 5, showing a profile of a connector according to one embodiment of the invention. For purposes of simplicity, structural details of the supplement bag itself (e.g. the closed zipper at the mouth, stitched seams, multiple layers of textile material, decorative elements) are not shown. There is shown a connector 50. The connector 50 includes a first member 52. Coupled to the first member 52 is a second member 53. Coupled to the second member 53 is a third member 54. In addition, the connector 50 has a profile 70.
As shown, the profile 70 of the connector 50 is U-shaped. The first member 52 is disposed within the supplemental bag (See e.g., Figure 1, Item 14). The second and third members 53 and 54, respectively, are disposed outside of the supplemental bag (See e.g., Figure 1, Item 14). As a result, the third member 54 of the connector 50 extends to function as a tongue by projecting through a slit (See e.g., Figure 3, Item 31) and into a buckle (See e.g., Figure 3, Item 30) of a main bag (See e.g., Figure 3, Item 11).
In one non-limiting embodiment, the first member 52 is coupled to the supplemental bag (See e.g., Figure 1, Item 14). The second member 53 extends from the first member 52, and the third member 54 extends from the second member 53 opposite the first member 52. The first and second members (52 and 53, respectively) are substantially parallel to each other such that they do not touch each other at distal ends thereof.
Figure 8 is a partial front perspective view of a latch assembly, showing a buckle removably coupled to a connector, according to one embodiment of the invention. There is shown a latch assembly 80. The latch assembly 80 includes a connector 50 removably coupled to a buckle 30. The buckle includes a buckle aperture 81 and buckle housing 82. The connector 50 includes a connector tongue 60. The connector tongue 60 is selectably disposed within the buckle aperture 81 and removably coupled to a pair of levers 83.
As shown, the buckle 30 includes a pair of levers 42, 83. The pair of levers 42, 83 may be rotatably coupled to the buckle housing 82 and may pivot about an axis. The pair of levers 42, 83 may pivot closed to couple to the connector tongue 60, and may pivot open to release the connector tongue 60. Accordingly, each lever 42, 83 may be an actuator, and may operate to couple and uncouple the connector tongue 60 to the buckle 30. More, the levers 42, 83, or actuators, may be buttons that are disposed opposite each other on the latch assembly 80. As a result, the pair of levers 42, 83 may function as push buttons for releasing the connector 50 from the buckle 30 upon simultaneous application of force to each lever 42, 83, or button.
The pair of levers 42, 83 are partially disposed within the buckle housing 81. Each lever 42, 83 is disposed along a side of the connector tongue 60 when the connector tongue 60 is disposed within the buckle housing 82, and thereby flank the connector tongue 60. Accordingly, a majority of the connector tongue 60 is disposed within the buckle 30 when the connector tongue 60 is coupled to the pair of levers 42, 83.
In one non-limiting embodiment of the invention, the connector tongue 60 may be disposed though the slit (See e.g., Figure 3, Item 31) and removably coupled to the buckle 30. As a result, the connector 50 and the buckle 30 comprise the latch assembly 80 for latching the main bag (See e.g., Figure 1, Item 11) to the supplemental bag (See e.g., Figure 1, Item 14). For instance, in one non-limiting embodiment, the latch assembly 80 may be such as an Embossed Pinch Latch, by Vintage Trailer Supply, of 27556 E. I-25 Frontage Rd., Santa Fe, NM 87508. More, in another non-limiting embodiment, the latch assembly 80 may be such as a push button release buckle of a Metal Buckle with "GM" Push Button, by SeatBeltsPlus, of 1338 Rocky Point Dr., Oceanside, CA 92056.
Accordingly, it may be that the levers 83, or actuators, may not be push buttons. Likewise, the levers 83, or actuators, may not be disposed opposite each other on the latch assembly 80.
Although the buckle is shown disposed on an interior of the main bag, the buckle may be disposed on an exterior of the main bag. Similarly, the connector, including connector tongue, may be disposed on an interior or exterior of the supplemental bag. Further, the supplemental bag may include a slit for allowing the buckle to travel through the slit into an interior of the supplemental bag.
It is expected that there could be numerous variations of the design of this invention. An example is that the main bag and/or supplemental bag may have any size and/or shape for transporting personal items. Additionally, although the figures illustrate the main bag and the supplemental bag as purses, it is envisioned that any type of bag may be used for the bag system, such as but not limited to: purses, backpacks, briefcases, computer cases, and luggage. It is also envisioned that the buckle may be hidden in the main bag by a divider, or pocket, of the main bag.
Finally, it is envisioned that the components of the device may be constructed of a variety of materials, such as, but not limited to: plastic, textiles, leather, metal, rubber, etc. and combinations thereof.
