A convertible baby carrier backpack system enables using a backpack portion as a backpack alone, a baby carrier portion as a baby carrier alone, or coupling the two portions together to form an integrated baby carrier backpack. A baby carrier has a carrier opening between a back panel and a carrier panel. A back panel is opposite the shoulder straps and configured away from a carrier when used as a baby carrier, while the carrier panel is configured proximal to the carrier when used as a baby carrier. An exemplary baby carrier portion has a carrier attachment feature configured on the back panel that enables detachable attachment of a backpack. An exemplary backpack portion has a backpack attachment feature that is configured to couple with the carrier attachment feature to enable detachable attachment of the backpack portion to the baby carrier portion.

Various systems and methods relate to an adaptive chair system having (i) a stowed mode in which the members of the chair frame are contained within a compact flexible multi-function bag (MFB), and (ii) a deployed mode in which the MFB is adapted to releasably couple to an arm of the chair to provide a multipurpose accessory chamber. In an illustrative example, the MFB may, for example, fold in on itself in an accessory mode. The MFB may provide various utilities for hikers, for example, by providing a case to receive an inflatable bladder so as to form a pillow. The MFB may receive a thermal liner adapted to maintain, for example, food or beverage temperature. Various embodiments may provide multifunctional services such as sun/rain canopy and footrest, for example, using the adaptive chair system in an ultralight form factor that is strong yet compact in the stowed mode.

A portable backpack chair with gear carrying webbing for use in efficiently carrying gear for camping, the beach or the like. The backpack chair provides a novel design that eases the ability to carry a collapsible chair, such as a beach chair, on the user's back along with accompanying gear such as a cooler, beach towel and supplies. The novel design comprises a beach chair with an pack carrier portion and support structure mounted to the bottom portion of the beach chair, and chair back and seat portions that include a plurality of rows of cross webbing fixedly connected to the chair backing and seat fabric at intervals whereby securing straps can be used to attach gear to the fabric portion by looping the securing straps through a spaces between the fabric and the webbing. The portable backpack chair allows the user to quickly and easily pack and carry a chair and gear with minimal effort.

Portable chairs including a detachable container. The container can be insulated for keeping beverages and food cold for an extended period. The folding chair preferably is designed and constructed for the demands of the outdoors. Various detachable, reconfigurable, and/or interchangeable features including the container, carrying straps, and cup holder. The container can be easily and conveniently attached and detached from the folding chair. The container can have exterior pockets which are welded and sealed to protect items contained within. The straps can have multiple different attachment points which allow multiple different carrying styles and reconfigurations including a backpack type carrying configuration, over-the-shoulder briefcase type carrying configuration, and across the body satchel type configuration, for example. The cupholder is interchangeable from each side of the folding chair and can be designed to accommodate various types of beverage containers including cups having a handle, a can, and a canteen, for example.

A bag includes a main compartment configured to accommodate equipment, and a foldable chair compartment disposed adjacent to the main compartment. The foldable chair compartment is configured to accommodate a foldable chair in a folded configuration.

A hard-sided backpack is provided having shoulder straps allowing the backpack to be carried on both shoulders of a user. The hard-sided backpack may have multiple features to enhance versatility and operation, including an insulated liner for operation as a cooler, a speaker to provide entertainment, a rigid cover for use as a seat, and the like.

A combined foldable chair and backpack that is movable between and open configuration for a user to sit thereon, and a folded configuration for a user to carry, is provided. The combined foldable chair and backpack includes a frame assembly, a fabric coupled to the frame assembly, a shoulder strap coupled to either the frame assembly or the fabric, and a storage compartment coupled to either the frame assembly or the fabric. The frame assembly includes a seat frame, a back frame pivotally coupled to the seat frame via a hinge assembly, a front leg pivotally coupled to the seat frame by a hinge, and a rear leg pivotally coupled to the hinge assembly by a hinge.

The MFB may provide various utilities for hikers, for example, by providing a case to receive an inflatable bladder so as to form a pillow. The MFB may receive a thermal liner adapted to maintain, for example, food or beverage temperature. Various embodiments may advantageously provide a rugged, water resistant MFB system in an ultralight form factor that serves as a multi-purpose accessory (e.g., to store items), yet provides a compact, adaptive chair frame containment.

The present invention relates to a single-legged portable working chair using a compression repulsive force of a spring body, wherein: when used, the telescopic single-legged portable working chair is worn on a user's body such that, when the user sits down, the spring body is compressed by the weight of the user's body to store power, and when the user stands up, the spring body pushes up the user's body using the compressed power, so that the power consumption required for the sitting and standing actions of the body can be reduced; when the user repeatedly lifts a weight, the load applied to the user's joints and muscles is alleviated by the magnitude of a repulsive force of the spring body.
