The present disclosure relates to foldable chairs with storage containers, and more particularly, a reclinable foldable chair, with a storage container, that can be carried or worn on the shoulders of a user when the chair is folded.
Combined chair and backpack designs generally fall into one of two groups. The first group includes tent-like assemblies which utilize a generally scissor-like or X-shaped frame and a fabric coupled to the frame. When these chairs are stored, the frame closes to a planar position and the fabric seat is relaxed and folded between the frame members. The second group uses a parallelogram frame, in which the fabric chair seat is carried in its own frame and is always tensioned, regardless of whether the chair is in an open seating configuration or in a folded storage configuration.
When a user desires to carry the folded chair on his or her back, components of the folded chair often rest against undesired areas of the user's back and are generally uncomfortable to carry due to the unbalanced weight of the components of the chair or storage area when the chair is in the folded configuration. Additionally, while current chairs are foldable, include storage areas, and are wearable by a user, the current designs do not consider protecting the storage area of the chair when the chair is folded, thus leaving the storage area (and items stored therein) vulnerable to damage.
The instant disclosure provides for a foldable chair that addresses the above-noted shortcomings and others not specifically listed above.
A combined foldable chair and backpack apparatus that is movable between and open configuration for a user to sit thereon, and a folded configuration for a user to carry, is provided.

Embodiments of the present disclosure are described herein with reference to the accompanying drawings, wherein:
Embodiments of the present disclosure are now described in detail with reference to the drawings in which like reference numerals designate identical or corresponding elements in each of the several views. Throughout this description, the term “proximal” or “front” refers to the portion of the chair apparatus or component thereof that is closest to a user when the chair apparatus is in the open, unfolded, configuration (for seating) and the term “distal,” “back,” or “rear” refers to the portion of the chair apparatus or component thereof that is farthest from the user when the chair apparatus is in the open, unfolded, configuration.
As will be described in detail below, provided is a combined foldable chair and storage backpack apparatus configured to transition from a reclinable chair for a user to be seated thereon to a portable wearable storage apparatus to be carried by a user and to store items therein. The chair apparatus includes a tubular frame having, for example, a series of interconnected tubes, a fabric attached to the tubes, and a hinge assembly, which together provide structural support for use as a chair with a seat and a reclinable back and for quick transition between a folded configuration for carrying the apparatus and an open configuration for sitting on the apparatus. Additionally, the chair apparatus of the instant disclosure includes a storage container that is protected and surrounded by components of the frame assembly when the chair is in the folded configuration. Additionally, the chair apparatus of the instant disclosure is comfortably worn by a user when in the folded configuration due to the balanced nature of the weight of its respective components and the regions defined by the components for storage of the remaining components.

The left hinge assembly 210 is directly coupled to the right hinge assembly 220 via the rear crossbar 150 of the seat frame 140. Any of the above-described, or below-described, couplings may be replaced with or supplemented by a screw, a nut and bolt, adhesive, pop-up fasteners, interlocking components, or any combinations thereof.
In one aspect, the left seat finger 212 and the left armrest finger 214 of the left hinge assembly 210 are fixed in position, and non-movable, relative to each other, such that the left side frame of the seat frame 142 is not movable relative to the left armrest 146.

Via this pivotable connection, the front leg 110 is movable between an extended configuration, where the front leg 110 is substantially perpendicular to the longitudinal axis X-X of the seat frame 140 (as shown in
The shape of the rear leg 120 is defined by a rear leg left straight tube 1201, a rear leg left radial tube 1202 friction fitted to the rear leg straight tube 1201, a rear leg straight tube 1203 friction fitted to the rear leg left radial tube 1202, a rear leg right radial tube 1204 friction fitted to the rear leg straight tube 1203, and a rear leg right straight tube 1205 friction fitted to the rear leg right radial tube 1204 to define a U-shaped rear leg 120.
The rear leg 120 is pivotally coupled to the left hinge assembly 210 via a left rear leg hinge 122 and the right hinge assembly 220 via a right rear leg hinge 124. Alternatively, the rear leg 120 may be pivotally coupled to any portion of the seat frame 140, via a left rear leg hinge 122 and a right real leg hinge 124, such that the rear leg 120 may pivot about the seat frame 140.

Via this connection to the left hinge assembly 210 and the right hinge assembly 220, the back frame 130 is movable between an extended configuration, where the back frame 130 is substantially perpendicular to the longitudinal axis X-X of the seat frame 140 (as shown in
With brief reference to
Right backrest finger 226 is cylindrically shaped and extends from backrest hinge 2202 for connection to the back frame 130 and right armrest finger 224 is cylindrical in shape and extends from housing half 2201a. Half of right seat finger 222 (semi-cylindrical in shape) extends from housing half 2201a while the other half of right seat finger 222 (semi-cylindrical in shape) extends from housing half 2201b to define the cylindrical shape of right seat finger 222 when combined. In particular, when housing half 2201a and housing half 2201b are joined together, the full right seat finger 222 is formed.
Pins 2202a are arranged in a circular formation on one side of backrest hinge 2202 and pins 2202b are arranged in a circular formation on the other side of backrest hinge 2202. Pins 2202a are positioned in respective holes 2209a defined by first ratchet disc 2203a and pins 2202b are positioned in respective holes 2209b defined by second ratchet disc 2203b such that pivotal movement of backrest hinge 2202 about the pivot axis defined by bolt 2211a causes corresponding pivotal movement of each of first ratchet disc 2203a and second ratchet disc 2203b. The right outer top pin and the right outer bottom pin of respective pins 2202a and pins 2202b extend further in distance from the respective side of backrest hinge 2202 than the other six pins of pins 2202a and pins 2202b such that the right outer top pin and the right outer bottom pin of respective pins 2202a and pins 2202b protrude from the respective holes 2209a and the respective holes 2209b. The protrusion of these pins is for the purpose of constraining the recliner reset 2204 between them such that when a protruding pin contacts a side of recliner reset 2204 via pivotal movement of backrest hinge 2202, the continued movement of the backrest hinge 2202 causes corresponding pivotal movement of the recliner reset 2204.
It is envisioned that hinge assembly 210 and/or hinge assembly 220 may include some, all, or none of the components of the ratchet assembly 220a described above with respect to
