The invention relates to a backpack or case, which, in the closed state, is formed or shaped from substantially an underside, upper side, lateral surfaces, a surface to be carried on the back and a front surface, wherein an opening region is formed on or along a surface (3) which is formed with at least one fold-down flap (13), whereby a substantially complete opening (2) of the substantially tub-shaped backpack body is made on the elongated surface to be carried on the back and on the at least one fold-down flap, by means of at least one zip closure (5), and wherein the surface to be carried on the back is provided with backpack straps.

A pressure-relieving back pack, comprising: a pack body (1), a pressure-relieving plate (2), a pressure-relieving assembly, two straps (4), and a supporting plate. The supporting plate is provided at a rear part of the pack body (1). The pressure-relieving plate (2) is provided at a side of the rear part of the pack body (1) near to the back. The pressure-relieving assembly comprises a spring mechanism and a hollow casing (33). The casing (33) is mounted at the rear part of the pack body (1). The spring mechanism is detachably provided inside the casing (33). The spring mechanism comprises a compression spring (31) and a retractable rod (32). The compression spring (31) is sleeved around and position-limited with respect to the retractable rod (32). A second end (322) of the retractable rod (32) and the compression spring (31) are position-limited within the casing (33). A first end (321) of the retractable rod (32) is located outside the casing (33) and can extend and retract upward and downward relative to a first end of the casing (33). The first end (321) of the retractable rod (32) and a lower end of the pressure-relieving plate (2) are detachably connected. An upper end of the pressure-relieving plate (2) is connected to an upper end of the strap (4). A lower end of the strap (4) is connected to a lower end of a back side of the pack body (1). The pressure-relieving back pack can meet different loading needs by changing the compression spring (31) of the pressure-relieving assembly.

A panel attachable to a backpack body. The panel having at least one through-hole formed therein to allow air to flow into a gap defined between the panel and the backpack body. An air-moving device is mountable to the panel, with an outer portion of the air-moving device extending forwardly from the panel and an inner portion of the air-moving device positioned in the gap. The air-moving device causes air to flow into the gap through the at least one through-hole and into one or more inlets of the inner portion. The air-moving device causes air to flow out one or more outlets of the outer portion.

A backpack assembly includes a bag body and a carrying accessory. The carrying accessory includes a back plate, a bag strap, and a waistband. The back plate has a first engaging portion and a second engaging portion which are opposite to each other, and has a middle portion located between the first engaging portion and the second engaging portion. The first engaging portion is adapted to be engaged with the bag body. A first connecting hole is disposed on the middle portion. The bag strap has two shoulder straps and a first connecting strap which passes through the first connecting hole. A first fastening member is disposed on each of the shoulder straps. The waistband engaged with the second engaging portion is connected to the first fastening members. With such design, the backpack assembly could be engaged with different bag bodies with different functions, different capacities, or different sizes.

A combination backpack with removable back support has a backpack portion and a back support portion which are detachably connected to each other. This allows for use of a back support and backpack both together and separately, by utilizing a back support while wearing a backpack when connected and utilizing a back support separately on a seat or chair when detached. The back support portion will attach to the outside of the backpack component.

A backpack for a cylindrical shaped object, such as a utility bucket, is disclosed and includes a generally cylindrical shaped body portion with an open top and a bottom and a pair of a pair of shoulder straps attached to the top and bottom of the body portion, the attachment points for the straps at the top are spaced apart by at least a hundred and sixty degrees (160) and eighty degrees (80) from a lateral center line of the body portion relative to one another. A plurality of pockets may be disposed about the perimeter of the body portion and the backpack may also include a grab handle and chest strap.

A backpack may comprise a main body defining a first compartment, a first shoulder strap extending from the main body, a second shoulder strap extending from the main body, a cinching layer disposed adjacent an exterior surface of the main body, a first cinching cord coupled to the first shoulder strap and the second shoulder strap, and a second cinching cord coupled to the main body and extending through at least a portion of the cinching layer, wherein the second cinching cord is slideably coupled to the first cinching cord such that a tension applied to the first cinching cord causes the cinching layer to apply a compression force from the cinching layer toward the front exterior surface of the main body.

A carrier assembly for a harness for carrying a handheld motor-driven work tool, the carrier assembly including a back plate having connections for shoulder straps, a hip belt, and a manner for attaching the work tool. The back plate is arranged to be connected to the hip belt by a pivotal connection joint to allow rotation about an axis substantially perpendicular to a plane defined by the back plate.

A load-reducing massage backpack comprising the pack body and the back belt. An interlayer with an upper opening is arranged on the pack body against the back, an elastic fixed laminate is provided in the interlayer, the lower end of the fixed laminate is provided at the bottom of the interlayer and the upper end can extend out of the opening and is connected to the back belt, and the back of the pack body is against the waist and the massage apparatus. The present invention overcomes the defects existing in the prior backpack without massage function and in the prior massagers which only massage the waist, shoulder or back alone but cannot massage these positions simultaneously. An elastic fixed laminate is arranged on the backpack and a massage apparatus is disposed on the fixed laminate to massage the waist, shoulder and back. The massage apparatus is easy, flexible and can massage one or more positions simultaneously, support change of the massage position based on the user's demand, and be removed and used separately.

A backpack may comprise a main body defining a first compartment, a first shoulder strap extending from the main body, a second shoulder strap extending from the main body, a cinching layer disposed adjacent an exterior surface of the main body, a first cinching cord coupled to the first shoulder strap and the second shoulder strap, and a second cinching cord coupled to the main body and extending through at least a portion of the cinching layer, wherein the second cinching cord is slideably coupled to the first cinching cord such that a tension applied to the first cinching cord causes the cinching layer to apply a compression force from the cinching layer toward the front exterior surface of the main body.
