The present disclosure relates to packable chairs and specifically to packable chairs that transform between a chair configuration, a collapsed configuration, and a storage configuration.
Packable chairs are useful for transporting a chair to a variety of locations such as concerts, parties, campsites, beaches, etc. The packable chair can be folded or collapsed into a reduced size and then easily transported to the location in a vehicle or carried by a person. Once at the location, the packable chair can be unfolded or unpacked into a chair that can then be used for seating and holding beverages.
Attending a concert, a party, a campsite, a beach, etc. typically includes not only a packable chair but many other items such as beverages for a concert or party, supplies for a campsite, and towels and umbrellas for a beach. Moreover, attendance usually includes parking a vehicle away from the exact location of the concert or beach, and a person makes multiple trips to transport the packable chair and other items to the location of the concert or beach. Further still, a person needs to bring additional items such as a backpack or a towing solution for a cooler. These multiple trips are an additional effort that must be expended on the part of the person, and the additional items are an added cost. Thus, there is a long felt but unmet need to simplify and improve the trip and transportation process between, for instance, a vehicle and the final location of the concert or beach.
The above shortcomings and other needs are addressed by the various embodiments and configurations of the present disclosure. It is an objective of the present disclosure to provide a packable chair that is transformable between at least two configurations: a first chair configuration and a second storage configuration where items can be stored and transported within the chair between, for instance, a vehicle and the final location of the concert or beach.
It is an aspect of embodiments of the present disclosure to provide a packable chair with multiple portions that serve as both a part of a chair in the chair configuration and a part defining a storage volume in the storage configuration. In one embodiment, the chair has four portions: a back portion, a seat portion, a head rest portion, and a leg rest portion. At least two of these portions are movable to transform the packable chair between configurations. For instance, the head rest portion and leg rest portions move and selectively connect to each other to define an enclosed volume in which containers and other items can be stored.
In embodiments, the hinges or joints between portions are lockable in preset positions that enable the chair to be set in different positions. These hinges allow a user to change the chair quickly and conveniently from the chair configuration to the storage configuration. In other embodiments, the portions are rotatable relative to each other but a friction or interference force must first be overcome to initiate the rotation. This force is selected such that the portions will not readily move once in the chair configuration or storage configuration but is still small enough that most people can physically overcome the force and move the portions relative to each other.
It is another aspect of embodiments of the present disclosure to provide a packable chair with a plurality of containers that can be stored in the enclosed volume defined by the packable chair in a storage configuration. The containers can store items and supplies that would otherwise need to be individually carried or transported to an event location like a beach or campsite. The containers can include features that promote the transportation of items. For example, the containers can be stackable where a feature on a bottom side of one container can match a feature on a top side of an adjacent container to help prevent relative movement of the containers during transportation. In one embodiment, a protrusion on the bottom side of a container extends into a recess in the top side of an adjacent container. Further still, a container that requires power for heating or cooling the environment within the container can selectively connect to a cable or plug that draws power from a battery and/or a solar panel on the head rest portion.
Next, it is an aspect of embodiments of the present disclosure to provide a packable chair with features that further promote the transportation of contents within an enclosed volume of the packable chair in the storage configuration. The sides of the volume can be defined by panels that can be attached to the back and leg rest portions. These panels can be formed from fabric sheets that attach through Velcro® or hook and loop fabric. In embodiments the panels are attached to a portion of the chair and rolled into a stored configuration. Further still, additional portions can be included that rotate relative to another portion from one position where the additional portions define the left and right sides of the enclosed volume, and then to another position where the additional portions do not obstruct a user in the chair configuration.
In embodiments, the seat portion contains a second seat hinge that separates the seat portion into first and second seat portions. In these embodiments, the storage configuration can be achieved through aligning the back portion and first seat portion such that they are approximately parallel, and the head rest positioned closer to the second seat hinge than the foot or wheel. The second seat portion is rotated such that it is at an approximately 90-degree angle with the first seat hinge and extends away from the back portion. The leg rest portion is rotated such that it is approximately 90 degrees with the second seat portion and is approximately parallel to the back portion and first seat portion. The head rest can be rotated outwards such that it can be connected to the end of the leg rest portion. In embodiments, the kick stand is folded such that it is approximately parallel with the back portion. Straps can then be attached to the kick stand and the back portion such that a user can wear the chair while it is in the storage position.
In a further embodiment, the leg of the chair ends in a wheel. When in the storage configuration, as stated above a user can wear the chair as a backpack. Alternatively, a user can hold a handle located on the distal end of the kickstand and roll the chair while in the storage configuration. This allows for easy transportation when heavy articles, such as a cooler, are stored in the enclosed volume.
In various embodiments, the packable chair can transform into a third configuration. In this configuration, the packable chair is transported between locations without transporting containers or otherwise needing to utilize the enclosed volume. The head rest portion can be allowed to simply fold flat against the back portion for transportation in this third configuration. The seat portion is rotated upwards against the back portion and then secured in place. In one embodiment, a fastener is used to secure the seat portion in this position. For example, a loop or lashing can tie one side of the seat portion to the back portion. Then, with the seat portion secured, the leg rest can be allowed to simply fold flat against the seat portion. With this third configuration, the packable chair can be transported from location to location and deployed as a chair without transporting any containers. In embodiments, this third configuration can include a small storage compartment formed by the side panels. In these embodiments, the small storage compartment may be sized to store items such as a jacket or water bottle.
In further embodiments, the seat portion can include a second seat hinge. In these embodiments, the seat portion is split into two sections, a first, proximal seat section and a second, distal seat section. The first seat section is connected to the back portion by the chair hinge. Further, in embodiments, the first seat portion extends beyond the seat hinge and ends with a foot or wheel. The second seat section is connected to the leg rest portion by a leg rest hinge. The first and second seat sections are rotatably connected by the second seat hinge. In these embodiments, the third collapsed configuration is formed by rotating the kick stand such that it is approximately parallel to the back portion. The first seat portion is aligned with the back portion such that the head rest is closer to the second seat hinge than the first seat hinge. The second seat portion is rotated to be approximately parallel to the first seat portion but extend away from the head rest. The leg rest is aligned approximately parallel to the back portion and extends towards the head rest. A user is then able to hold the handle end of the kick stand and, in embodiments containing a wheel at the end of the first seat portion, is able to roll the seat to a desired location. In embodiments the user may also attach shoulder straps to the kickstand and back portions to wear the chair as a backpack.
In various embodiments, the packable chair can include wheels to help tow or otherwise transport the packable chair. For instance, the wheels are connected to a hinge or any of the portions. A user can grasp the upper end of the packable chair, or a handle extending from the upper end of the packable chair and then tow the chair while the chair is in the storage configuration. Once at the final location, the chair can transform into another configuration.
In embodiments of the disclosure, the packable chair has features that help a user carry the packable chair in the storage configuration. Shoulder straps can be connected to a kickstand or other portions of the packable chair to help a user bear the weight of the chair and the containers or other items stored within the chair. In embodiments, a waist belt is also connected to the kickstand or other portions of the chair to help a user bear even more weight.

A head rest 28 is connected to the back portion 12. In one non-limiting example, the head rest 28 is connected to a proximal end of the back portion 12. The depicted embodiment of the head rest 28 comprises a cushion and a connection feature 30. In the depicted embodiment, the connection feature 30 is a closed strap that loops around a proximal cross bar of the back portion 12. In embodiments the head rest 28 contains a fastener opposite the connection feature 30. The fastener can be used to secure the head rest to a second portion of the chair (e.g., when the chair is in the storage configuration, as described in detail further herein). Although not shown, the chair may additionally have any number of cushions that are operable to couple to the back portion 12 at any position (and/or the head rest 28 is repositionable) along the length of the back portion 12 (e.g., to provide head support, neck support, shoulder or upper back support, middle back support, lumbar or lower back support, or the like). It is noted that the proximal and distal ends of the chair 10 are marked in
In embodiments, the seat portion 14 contains a second seat hinge 22 that separates the seat portion into a first, proximal seat portion 16 (or first, proximal seat section 16) and a second, distal seat portion 18 (or second, distal seat section 18). In these embodiments, the second seat portion 18 can be folded to create a vertical seat stand that supports the proximal seat portion 16 and provides distance between the ground and the second seat hinge 22.
A leg rest portion 32 is connected to a distal end of the second seat portion 18 at a leg rest hinge 34. The leg rest portion 32 can have a length that is substantially or approximately equal to a length of the back portion 12. In embodiments, the leg rest portion 32 has a length that is approximately equal to a length of the back portion 12 minus a length of the first or second seat portion 16, 18. With the leg rest 32 substantially equal in length to the back portion 12 minus a length of the first or second seat portions 16, 18 and the head rest and second seat portions 28, 18 substantially equal in length, the shape of the packable chair 10 in
While four portions 12, 18, 28, 32 are depicted as defining the volume in the storage configuration, it will be appreciated that a fewer or greater number of portions can define the volume. For example, the packable chair 10 can have additional portions that rotate relative to one of the portions 12, 18, 28, 32 to define the left and/or right sides of the volume. Moreover, the back portion 12 and the head rest can be combined into a single portion, or the back portion 12 and the seat portion 14 can be combined into a single portion. In further embodiments, the seat portion 14 can be split into two separate sections 16, 18 separated by a second seat hinge 22. In various embodiments, the volume 44 is not a rectangular prism but another shape. For instance, the portions can be curved and form a volume with an ovoid shape.
In embodiments, a sleeve 64 can be used to cover portions of the chair 10. This sleeve 64 can span a gap between portions and provide a support for a user's body when sitting in the chair 10. The sleeve 64 can also provide a panel for securing the contents of the volume 44 when in the storage configuration shown in
The kickstand 36 can be adjustable in length where one portion telescopes relative to another portion.

In addition to being worn as a backpack, the chair 10 can be placed on the ground and rolled on its wheels 26 when the user holds handle 56. Handles are placed on both the distal end of the kickstand 36 and the end of the leg rest 32. These allow the user to roll the chair when in both the chair configuration and in the storage configuration. In embodiments, the kickstand 36 is telescopic and can be extended beyond the back portion 12 to provide a longer handle in the storage configuration.
The inner surfaces of the back portion 12, the seat portion 14, the head rest portion 28, and the leg rest 32 define an enclosed volume 44 with a rectangular prism shape. Optionally, a plurality of containers can be stacked and positioned in the enclosed volume 44 for transportation as the user wears the chair 10 as a backpack.
Additional features are contemplated to help secure contents within the enclosed volume 44. For instance, straps 58 can extend from the sides of the seat and/or back portions 12, 14 to define the sides of the enclosed volume 44 and retain the contents within the volume. In embodiments, a lashing or portion of fabric can be attached to one of the portions 12, 14, 28, and 32 in the chair configuration to support a user, but then be reconfigured to span two or more portions in the storage configuration to define the sides of the volume 44.

Generally, the chair 70 comprises multiple portions or sections that can move to transform the chair 70 between the chair configuration and a collapsed configuration (e.g., as described in detail further herein). A back portion 72 and a seat portion 74 are joined together via one or more seat hinges 76, such that the back portion 72 and the seat portion 74 are rotatable relative to each other. It will be appreciated that in some embodiments, the back portion 72 and the seat portion 74 are fixed relative to each other, for example, at an angle of between about 80 degrees and 100 degrees, or at an angle of approximately 90 degrees. It is noted that the proximal and distal ends of the chair 70 are marked in
In embodiments, the back portion 72 is separated into a first, proximal back portion 78 (or first, proximal back section 78) and a second, distal back portion 80 (or second, distal back section 80) via one or more back hinges 82. In these embodiments, the second back section 80 can be folded between an unfolded position for the chair configuration and a folded position for the collapsed configuration in which the first back section 78 rests against or proximate to the second back section 80. It is noted herein that the back portion 72 is not limited to two sections, and may include one or three or more sections, either hinged or unhinged, without departing from the scope of the present disclosure.
A head rest 84 is optionally connected to the back portion 72. In one non-limiting example, the head rest 84 is connected to a proximal end of the back portion 72. The example embodiment of the head rest 84 comprises a cushion and a connection feature 86. In the example embodiment, the connection feature 86 is a closed strap (or closeable strap with an interlocking assembly on separate portions of the strap) that loops around the back portion 72 and/or couples to a seat covering on the back portion 72. It is noted that the head rest 84 may additionally have any number of cushions that are operable to couple to the back portion 72 at any position (and/or the head rest 84 is repositionable) along the length of the back portion 72 (e.g., to provide head support, neck support, shoulder or upper back support, middle back support, lumbar or lower back support, or the like).
In embodiments, the seat portion 74 is separated into a first, proximal seat portion 88 (or first, proximal seat section 88) and a second, distal seat portion 90 (or second, proximal seat section 90) by one or more seat hinges 76. In these embodiments, the first seat section 88 can support the chair 70 by contact with the ground. In some embodiments the first seat section 88 forms an angled, approximately vertical, or vertical seat stand that provides distance between the ground (or a ground surface) and the seat hinge 76 (and additionally the back portion 72 and the second seat section 90). In one non-limiting embodiment, the seat portion 74 is not hinged between the first seat section 88 and the second seat section 90. Accordingly, the seat portion 74 is optionally formed of one piece of material, such as a metal tube bent into the appropriate shape. However, it is contemplated that a hinge may be positioned between the first seat section 88 and the second seat section 90 to provide greater control of the angle between the first seat section 88 and the ground, without departing from the scope of the present disclosure. It is noted herein that the seat portion 74 is not limited to two sections, and may include one or three or more sections, either hinged or unhinged, without departing from the scope of the present disclosure.
A leg rest portion 92 is connected to a distal end of the seat portion 74 by one or more leg rest hinges 94. In embodiments, the leg rest portion 92 extends away from the distal end of the second seat section 90. The leg rest portion 92 forms a nonzero angle with the seat portion 74 to support the seat portion 74 (and the rest of the chair 70) in the chair configuration. The leg rest portion 92 may be straight or include an angle along the length from a proximal end to a distal end. For example, the leg rest portion 92 may be configured with a selected straightness or angle to produce a particular height of the distal end of the seat portion 74 relative to the ground, either in addition to or instead of the positioning made possible by the leg rest hinge 94.
A kickstand portion 96 is connected to the back portion 72 via a kickstand hinge 98. For example, the kickstand portion 96 may be connected to the second back section 80 proximate to the back hinge 82. In embodiments, the kickstand portion 96 is positioned on an outer surface of the back portion 72 or, stated differently, the kickstand portion 96 extends away from the outer surface of the back portion 72. The kickstand portion 96 forms a nonzero angle with the back portion 72 to support the back portion 72 (and the rest of the chair 70) in the chair configuration. The kickstand portion 96 may be straight from the kickstand hinge 98 to a free end of the kickstand (free end being a portion of the kickstand configured to contact the ground). Alternatively, the kickstand portion 96 optionally includes an angle along the length from a proximal end to a distal end. The angle may be formed by a bend in the kickstand 96 between the kickstand hinge and the free end of the kickstand, such that the kickstand 96 is optionally formed of one piece of material, such as a metal tube bent into the appropriate shape. For example, the kickstand portion 96 may be configured with a selected straightness or angle to produce a particular height of the back portion 72 relative to the ground, either in addition to or instead of the positioning made possible by the kickstand hinge 98. As illustrated in the example embodiments of
It is noted that the second back section 80 may be straight or include an angle along the length from a proximal end to a distal end. For example, the second back section 80 may be configured with a selected straightness or angle to produce a particular planar surface or curved surface with the seat portion 74. For instance, the second back section 80 may include a bend 79 defining an upper region 81 of the second back section 80 and a lower region 83 of the second back section 80, to increase a radius of an angle defined by the transition between the back portion 72 and the seat portion 74 at the seat hinge 76. For example, in embodiments, the bend in the second back section 80 alters the direction of a frame member 104 of the back portion by approximately 40 degrees. Without the bend 79 in the second back section 80, the second back section 80 and the seat portion 74 would intersect at an angle of approximately 120 degrees which might be uncomfortable. However, in embodiments that include the bend 79, the second back section 80 and the seat portion 74 may intersect at an angle of between about 150 to 165 degrees, or about 160 degrees.
The back portion 72, the seat portion 74, the leg rest portion 92, and the kickstand portion 96 each include one or more frame members 104. The frame members 104 may be fabricated from a rigid material such as metal or high-density plastic that may be solid or hollow. In one non-limiting example, the rigid material for the frame members 104 is a 1″ tubular aluminum. The frame members 104 may be single-piece or may comprise multiple sections. In embodiments, the frame members 104 may include hinged or telescopic sections. Where the frame members 104 are telescopic, a frame member 104 can be adjustable in length with one section of the frame member 104 being able to telescope relative to another section of the frame member 104. The telescopic motion may be inhibited or locked in place using a friction-based connector that prevents the members from moving relative to each other. In addition, or in the alternative, bias detents in one frame member 104 section can selectively engage apertures or recesses in another frame member 104 section to establish the length of the respective frame member 104.
In embodiments, the chair 70 can include one or more seat coverings 106. The seat covering 106 may be formed with a sleeve 108 into which a frame member 104 passes and/or that wraps around the frame member 104 to join the frame member 104 and the seat covering 106. Alternatively, or in addition, the seat covering 106 be affixed to the frame members 104 (e.g., via an adhesive, a fastener, or the like).
The seat covering 106 may be a solid piece, or may include one or more apertures or openings 110. It is contemplated that the seat covering 106 can include a panel or pouch for holding or securing products (e.g., such as a personal electronic device, or the like), either for transport by a user or for access by the user (e.g., when sitting, reclining, or laying in the chair 70).
It is noted herein that
The one or more frame members 104 for each of the back portion 72, the seat portion 74, the leg rest portion 92, and the kickstand portion 96 at least partially define a perimeter or outer boundary for the respective portion. The seat covering 106 (e.g., fabricated from a more elastic or biasable material) can be positioned over a frame area 112 defined by the respective perimeters and/or be inserted within the frame area 112 to provide comfort to a user lounging in the chair 70. For example, the seat covering 106 can at least partially span the frame area 112 between the frame members 104 and provide support for a user when sitting, reclining, or laying in the chair 70.
As illustrated in
It will be appreciated that the chair 70 may be separated into a fewer or greater number of portions than the described portions 72, 74, 92, 96. For example, the chair 70 can have additional portions that rotate relative to one of the portions 72, 74, 92, 96. In addition, the back portion 72 can be a single portion, and/or the back portion 72 and the seat portion 74 can be combined into a single portion. Further, the leg rest portion 92 can be split into two or more separate sections. Further still, the seat portion 74, the leg rest portion 92, and/or the kickstand portion 96 can be split into two or more separate sections that are coupled by a hinge.

In other embodiments, one or more of the hinges 76, 82, 94, 98 can ratchet in one rotational direction until released. In still other embodiments, one or more of the hinges 76, 82, 94, 98 can be locked and secured in a desired position. Further still, one or more of the hinges 76, 82, 94, 98 can adjust the angle between adjoined portions 72, 74, 92, 96 and then be locked in place by a pin, clip, etc. Further, one or more of the hinges 76, 82, 94, 98 can include a friction or interference fit that holds an angle within the one or more of the hinges 76, 82, 94, 98 (and thus the respective portions 72, 74, 92, 96 adjoined via the hinges) unless and/or until a sufficient overcoming force is applied to the hinges 76, 82, 94, 98. For example, the friction or interference fit may be defined by a predetermined amount of force that is high enough to hold the position of the chair 70 when in use by the user in the chair configuration, but is low enough to be overcome by the application of a force by a user to transition the chair 70 between the chair configuration and the collapsed configuration).
In embodiments, the hinges 76, 82, 94, 98 may be coupled to the frame members 104 via fasteners 118 (e.g., rivets, screws, bolts, and the like). In addition or in the alternative, the hinges 76, 82, 94, 98 may include brackets 120 (e.g., full loop or partial loop brackets) that receive and engage with the frame members 104. In some embodiments, the brackets 120 are formed of a metal material. The brackets 120 generally include a bent portion (or saddle) configured to loop around a first frame member. The brackets also include two free ends arranged in an opposing relationship such that a second frame member may be positioned between the two free ends. A fastener 118 may then extend through a first free end, the second frame member, and a second free end to couple the second frame member 104 to the bracket 120.
In addition, open ends of the frame members 104 may be covered or otherwise protected by end caps 122. For example, the end caps 122 may prevent fluid or particulates from entering the frame members 104, and/or may prevent injury to a user caused by the open ends of the frame members 104.
In embodiments, the frame members 104 may include loops 124 that are operable to engage with the seat coverings 106 (e.g., as shown in

In embodiments, the chair 70 includes strap buckles 134 or other securing components which assist in tensioning or loosening the straps 126. Tensioning or loosening the straps 126 allows for the angle between the hinged portions 72, 74, 92, 96 to be adjusted. For example, the angle of regions of a seating surface of the chair 70 (e.g., as formed by the seat coverings 106) may be increased or decreased via the adjustment of the straps 126 relative to the hinged portions 72, 74, 92, 96. By way of another example, the height of regions of the seating surface of the chair 70 may be increased or decreased via the adjustment of the straps 126 relative to the hinged portions 72, 74, 92, 96.
In embodiments, a set of straps 126, strap rings 128 with strap fasteners 130 and/or strap brackets 132, and/or strap buckles 134 may form a strap assembly 136 of the chair 70. It is noted that the strap assembly 136 may be used in addition to or instead of hinges 76, 82, 94, and/or 98 that are capable of locking or are otherwise fixable at a desired angle. It is noted that utilizing only the strap assemblies 136 to set the angles between the portions 72, 74, 92, 96 of the chair 70 may reduce the complexity of the chair 70, providing a benefit to the manufacturer and/or the consumer in terms of cost and/or repairability. In addition, it is noted the strap assemblies 136 may be fully tightened when the chair 70 is in the collapsed configuration (e.g., as described in detail further herein) to keep the various portions 72, 74, 92, 96 together when the chair 70 is in the collapsed position.
As illustrated in
As illustrated in
Although
Although strap rings 128 (which form a closed loop) are shown in
Although not shown, the portions 72, 74, 92, 96 may include a strap (e.g., such as a backpack strap, shoulder strap, waist strap, or the like) so that a user can carry the packable chair 70 when the chair 70 is in the collapsed configuration.
Referring now to
When in the collapsed configuration, at least some lengths of the various portions 72, 74, 92, and 96 may be parallel or approximately parallel following rotation of respective joining hinges 76, 82, 94, 98. For example, the second kickstand section 102, the second back section 80, the first back section 78, the second seat section 90, and the leg rest portion 92 may be parallel or approximately parallel. This allows for a highly compact and packable chair when in the collapsed configuration that is able to unfold or expand to a large lounge or reclining chair configuration when in use. It is noted that “parallel” and “planar” may be understood to be the same, and “approximately parallel” and “approximately planar” may be understood to be the same.
As illustrated in
In additional embodiments, the transport strap assembly 138 may include a transport buckle or other securing component to assist in tensioning or loosening the transport strap 140. It is noted, however, that the transport strap 140 may be fabricated from a hook-and-loop assembly (e.g., Velcro® or other hook-and-loop fabric), such that the transport buckle or other securing component may not be necessary.
In one non-limiting example of the collapsed configuration, the first back section 78 is folded against (or proximate to) the second back section 80. The first back section 78 is also folded against (or proximate to) the second seat section 90, such that the first back section 78 is positioned between the second back section 80 and the second seat section 90. The leg rest portion 92 is folded against (or proximate to) the second seat section 90, such that the second seat section 90 is positioned between the first back section 78 and the leg rest portion 92. Finally, the second kickstand section 102 is folded against (or proximate to) the second back section 80, such that the second back section 80 is positioned between the first back section 78 and the second kickstand section 102. In this example, at least a length of each of the various sections 78, 80, 90, 102 and portion 92 are substantially parallel.
In the above example, the first kickstand section 100 can optionally be folded against the first seat section 88 due to the curvature of frame members 104 forming the first kickstand section 100 and the first seat section 88, such that at least a length of each of the first kickstand section 100 and the first seat section 88 are substantially parallel. In addition, where the second seat section 80 includes an upper region 81 and a lower region 83 separated by a bend 79, at least a second length of each of the first kickstand section 100, the first seat section 88, and the second back section 80 are substantially parallel. It is noted these lengths may be at an angle relative to the lengths of each of the various sections 78, 80, 90, 102 and portion 92 described in the previous paragraph.
Also in the above non-limiting example, the second kickstand portion 102 and the leg rest portion 92 are the most lateral components of the chair 70 (e.g., furthest from a midline through the chair 70, or the outermost portions of the chair) in the collapsed configuration. The transport strap assembly 138 includes a first transport strap ring 142 coupled to the second kickstand portion 102 via a first transport bracket 144 and transport fasteners 146, and a second strap ring 142 coupled to the leg rest portion 92 via a second transport bracket 144 and transport fasteners 146. The transport strap 140 is coupled is coupled to the transport strap rings 142.
Although not shown, the chair 70 may include a wheel able to roll along the ground. For example, the seat hinge 82 may include or be coupled to a wheel, and a frame member 104 (e.g., of the second seat section 90 or the first seat section 88) may be usable as a handle to pull the chair 70 in the collapsed configuration. By way of another example the leg rest portion 92 and/or the kickstand portion 96 may include or be coupled to a wheel, and a frame member 104 (e.g., of the first back section 78) may be usable as a handle to pull the chair 70 in the chair configuration. It is contemplated, however, that the chair 70 is fabricated from material that a user is able to pick up and transport without needing to roll the chair 70.
