This invention relates generally to a bag for carrying items, and, in particular, to a bag for carrying items that is reconfigurable to different volumes for different uses.
Bags for carrying items are well known. Such bags include, for example, backpacks, book bags, duffel bags, suitcases, and tote bags. These bags typically contain a main interior compartment, and may include additional internal and/or external pockets. At times, a user will need to carry more items than their bag is designed to carry, causing the user to bring an additional bag or carry some items by hand. Some known bags are expandable, allowing the carrying capacity of the bag to be increased.
U.S. Pat. No. 4,361,215 to Sawai discloses a gusseted suitcase having a body and a pair of gussets secured to the bottom of the body. The gussets are secured to the body by way of fasteners. When the fasteners are opened, the gussets unfold to increase the volume of the suitcase. Sawai is limiting in the amount that its expandable gussets can expand the volume of the suitcase.

A closure panel is releasably secured to the aperture when the bag is in a first configuration. A primary pocket is secured around a peripheral edge thereof to the aperture and to the closure panel. The primary pocket extends into the interior compartment to form an interior pocket accessible from an exterior of the bag when the bag is in the first configuration. The primary pocket extends outwardly from the exterior surface of the bag and is in communication with and expands the volume of the interior compartment when the bag is in a second configuration. The closure panel forms a portion of the primary pocket when the bag is in the second configuration.
In accordance with another aspect, a bag for carrying items has an interior compartment and an exterior surface. At least one aperture is formed in the exterior surface of the bag. The bag has at least one closure panel, with each closure panel covering a corresponding aperture when the bag is in a first configuration. The bag has at least one fastener, with each fastener releasably securing one of the closure panels to a corresponding aperture. The bag also has at least one pocket, with each pocket being secured around a peripheral edge thereof to a corresponding aperture and to a corresponding closure panel. The pocket extends into the interior compartment to form an interior pocket accessible from an exterior of the bag when the bag is in the first configuration, and extends outwardly from the exterior surface of the bag and is in communication with and expands the volume of the interior compartment when the bag is in a second configuration. The corresponding closure panel forms a portion of the pocket when the pocket extends outwardly from the exterior surface of the bag.
In accordance with a further aspect, a bag for carrying items has an interior compartment and an exterior surface. At least one aperture is formed in the exterior surface of the bag. The bag has at least one closure panel, with each closure panel covering a corresponding aperture when the bag is in a first configuration. The bag has at least one fastener, with each fastener releasably securing one of the closure panels to a corresponding aperture. The bag also has at least one primary pocket, with each primary pocket being secured around a peripheral edge thereof to a corresponding aperture and to a corresponding closure panel. The primary pocket extends into the interior compartment to form an interior pocket accessible from an exterior of the bag when the bag is in the first configuration. The primary pocket extends outwardly from the exterior surface of the bag and is in communication with and expands the volume of the interior compartment when the bag is in a second configuration. The corresponding closure panel forms a portion of the pocket when the pocket extends outwardly from the exterior surface of the bag. The bag has at least one secondary pocket, with each secondary pocket secured around a peripheral edge thereof to an aperture formed in a primary pocket and to a second closure panel releasably secured to the aperture formed in the primary pocket. The secondary pocket extends into the primary pocket to form a secondary interior pocket accessible from an exterior of the bag when the bag is in a third configuration, and extends outwardly from the exterior surface of the primary pocket and is in communication with and expands the volume of the interior compartment when the bag is in a fourth configuration. The second closure panel forms a portion of the secondary pocket when the secondary pocket extends outwardly from the exterior surface of the bag.
In accordance with yet another aspect, a bag for carrying items includes a bag having an interior compartment and an exterior surface. At least one aperture is formed in the exterior surface of the bag and a fastener releasably closes the aperture. A primary pocket is secured around a peripheral edge thereof to the aperture. The primary pocket extends into the interior compartment to form an interior pocket accessible from an exterior of the bag when the bag is in the first configuration. The primary pocket extends outwardly from the exterior surface of the bag and is in communication with and expands the volume of the interior compartment when the bag is in a second configuration. A releasable fastener is formed in the primary pocket and is configured to provide access to the interior compartment when the bag is in the first configuration and when the bag is in the second configuration.

Another preferred embodiment is shown in
In certain preferred embodiments, a panel 75 may be secured to aperture 64 closing off access between pocket 60 and interior compartment 52.
As illustrated here, both end panels 66 of duffel bag 46 have a pocket 60 secured thereto in order to form invertible pockets in each end. However, it is to be appreciated that pocket 60 may also, or alternatively, for example, be secured to an aperture formed in either or both side panels 70 of duffel bag 46. As illustrated here, a first releasable fastener such as zipper 72 is formed in pocket 60, allowing access to interior compartment 52 when pocket 60 is inverted to extend outwardly from the exterior surface of duffel bag 46, or to another pocket extending inwardly into pocket 60. A second releasable fastener 74 may also be included in pocket 60, allowing additional access to interior compartment 52, or to another pocket extending inwardly into pocket 60.
Another preferred embodiment is shown in
As illustrated here, both end panels 88 of bag 80 have a first pocket 82 secured thereto. However, it is to be appreciated that additional pockets may also, or alternatively, for example, be secured to apertures formed in either or both side panels 92 of bag 80. As illustrated here, a releasable fastener such as a zipper 94 is formed in first pocket 82, allowing access to interior compartment 81 when first pocket 82 is inverted and extends outwardly from bag 80 or to another pocket within first pocket 82.
In the illustrated embodiment, first pocket 82 includes a top panel 96, bottom panel 89, two side panels 100, and an end panel 102. A secondary, or second pocket 104 is secured about its peripheral edge 106 to an aperture 108 formed in end panel 102 of first pocket 82 and to a closure panel 109, allowing storage within first pocket 82 from the exterior in a third configuration. Closure panel 109 is secured to aperture 108 with a releasable fastener such as a zipper 110. When zipper 110 is in its open condition, second pocket 104 can be inverted and extended outwardly from first pocket 82 so as to greatly expand the volume of interior compartment 81 when the bag is in a fourth configuration, with closure panel 109 becoming the bottom panel of second pocket 104 in this configuration. Second pocket 104 also has a pair of side panels 111, an end panel 113, and a top panel 115.
As illustrated here, both first pockets 82 have a second pocket 104 secured to a respective aperture 108 in an end panel 102. Consequently, bag 80 is expandable in telescoping fashion with a plurality of nested pockets to increase and decrease the volume of interior compartment 81 to a large degree, depending on whether first pockets 82 and second pockets 104 extend inwardly into or extend outwardly from bag 80.
A strap 112 may be secured at opposed ends thereof to fasteners, such as loops 114 that are secured to bag 80. This allows a user to conveniently carry bag 80 with strap 112 when pockets 82 and 104 are in their internal positions within bag 80. Alternatively, as illustrated here, strap 112 may be secured at opposed ends thereof to fasteners, such as loops 116, on first pockets 82. Having different fasteners located at different positions on bag 80 allows for different orientations of strap 112 along bag 80, depending on which configuration of bag 80 is being utilized. Consequently, strap 112 can be secured to bag 80 in a first manner corresponding to one configuration of bag 80, and in a second manner corresponding to another configuration of bag 80.
Another preferred embodiment of a bag 120 is shown in
An aperture 130 at one end of bag 120 is closed by way of a releasable fastener such as a cinching cord 132. A pocket 134 is secured about its peripheral edge 136 to aperture 130. As illustrated in
Bag 120 can also be transformed to a second configuration, which is illustrated in
