The present invention relates to a bag usable as knee guards and, more specifically, to a bag usable as knee guards, which can retain heat or prevent damage to knees by surrounding the knees according to the needs of a user and can also be used as a bag. The subject matter of the present invention is a bag usable as knee guards, comprising: a first body which has one side open so as to form an accommodating space therein and surrounds a knee of a user with the knee bent; a second body which is formed so as to correspond to the first body and surrounds the other knee of the user with the knee bent; and a coupling means for coupling the open parts of the first and second bodies so as to form a bag shape, wherein: the first body has a cut part which can be opened and closed by a locking mechanism, and a storage pocket is formed inside the first body so as to communicate with the cut part, so that an article can be stored in the storage pocket by the locking mechanism even if the first and second bodies are uncoupled; each of the first and second bodies has connecting means for fixation formed at either end thereof so as to prevent detachment after being wrapped around the knees of the user; and the cross sections of the respective first and second bodies are in a triangular shape, so that the cross sections form a square shape when the first and second bodies are coupled to one another.

A light-weight, easily portable luggage combination is described. The combination comprises a garment bag and a general purpose bag and optionally a utility bag, wherein the garment bag and general purpose bag may be reversibly secured together or used separately if desired. The combination provides for a first interior space in the garment bag so that hanging clothes can be stored in the garment bag and a second interior space in the general purpose bag so that other items (for example, clothing, shoes, accessories, and toiletries) can be stored separately from the hanging clothes.

An assembled backpack includes a main compartment and an additional compartment. At least one first engaging member is disposed on the main compartment, and a strap is engaged with the main compartment. The additional compartment has a first side edge portion provided with a second engaging member and a second side edge portion provided with a second engaging member which are opposite to each other. The second engaging member of one of the first side edge portion and the second engaging member is detachably connected to the first engaging member, so the additional compartment is connected to the main compartment. The additional compartment has a first cloth and a second cloth positioned facing opposite directions. A first sealing member is disposed at an edge of a first opening of the first cloth. A second sealing member is disposed at an edge of a second opening of the second cloth.

Presented herein is a modular backpack comprising a front module and a back module, with the front module releasably attached to the back module via a connection between an attachment element of the front module and an attachment element of the back module. The modular backpack system can include any number of center modules positioned between the front module and the back module and releasably attached to both the front and back modules. To be a large capacity backpack, the modular backpack system can include a back module, the appropriate number of center modules, and a front module. To be a small capacity backpack, the modular backpack system can simply include a front module with a number of pockets and a back module. Accordingly, the modular backpack system thus enables the user to easily and quickly customize their backpack as needed based on the occasion.

In various embodiments, a carrying bag includes a carrying bag body formed by a security panel assembly comprising a cut-resistant fabric or mesh, with a strap channel having at least two spaced-apart reinforced channel openings; and a carrying strap comprising: first and second wire cables; a first flexible material having a first lateral region folded around the first wire cable to enclose the first wire cable and a second lateral region folded around the second wire cable to enclose the second wire cable; and a second flexible material arranged on or over a central region of the first flexible material. Representative embodiments may include a water-resistant pocket coupled to a protected seam and extending to an exterior of the carrying bag body; and a fastener to close the water-resistant pocket external to the carrying bag body.

A configurable bag is provided. The configurable bag has plurality of various interconnecting storage compartments (or modules). The interconnecting storage compartments may be selectively used to store various objects such as, for example, shoes, clean clothes, dirty clothes, toiletries, etc. The interconnecting storage compartments may be selectively secured vertically to each other so as to be able to be easily fit within, for example, a standard vertical gym locker. Retractable hooks may be secured to the sides of the interconnecting storage compartments so as to allow the assembled device to hang vertically from a hanger poll. The storage compartments may allow for both front and top access into the interior of the device.

A backpack for large objects is provided, which includes a main body, two straps, a first wing, a second wing, and an extended piece, wherein two ends of each of the straps are respectively connected to the rear of the main body, and the straps are used as shoulder straps. The main body has two opposite sides which are respectively connected to the first wing and the second wing, wherein the first wing and the second wing are connected to each other detachably. The first wing, the second wing, and the main body enclose and form a first holding space. The extended piece is connected to the main body close to either a bottom opening or a top opening of the first holding space.

A connector assembly for releasably connecting a first container to a second container, using male connector(s) and corresponding female connector(s) attached to each container, each female connector having a recess for receiving a portion of a male connector. The connector assembly has at least one pawl pivotable between a retracted position and extended position, a pawl retractor, and pawl extender(s) biasing the pawl(s) toward the extended position. The male connector(s) and female connector(s) are releasably locked together by moving the pawl retractor to a position reducing a biasing force of the pawl retractor on the pawl(s) and thereby allowing a biasing force of the pawl extender(s) to pivot the pawl(s) to the extended position against an engaging surface and releasably lock the male connector(s) to the female connector(s). The male connector(s) and female connector(s) are unlocked by moving the pawl retractor to pivot the pawl(s) away from the engaging surface.

Provided is a lunch box container including a lower housing that is formed to have an inner containing space; an upper housing that is hinged to one edge of the lower housing and is rotatable; an inner case contained in the lower housing and provided with partition walls to separate a plurality of inner spaces; and a locking wing that is formed on the other edge of the lower housing or the upper housing. The upper housing includes a trench portion formed on a lower surface to correspond to an upper end portion of the inner case.

An adaptable handbag system enables a user to customize the capacity of their hand bag by adding or removing bags from a carrying ring. The bags are attached to the ring via a hinge and attachment point to allow the bag to move with respect to the carrying ring. The bags have different shapes and markings to allow for quick identification even in less than optimal viewing conditions.
