[0002] The present disclosure is directed to a foldable chair, and more particularly to a customizable foldable chair that has connectors for cup holders, book holders, and parasols, as well as a frame with removable covers.

Description of Related Art

[0003] Chairs come in a variety of different styles and can be used for different settings. For example, dining chairs are used to comfortably eat at a table while office chairs are used to work at a desk, and beach chairs or camping chairs can be used outdoors. Traditionally, chairs used for outdoor activities do not have the necessary structure or support to assist users during common outdoor tasks, such as eating a meal. As a result, individuals are often forced to use makeshift solutions, or require users to use multiple separate components. These solutions are often unstable and prone to failure, leading to spills, accidents, and inconvenience. Additionally, if a chair gets damaged (e.g., the seat gets stained, or the seat material rips) the entire chair must be replaced. Furthermore, some chairs may be overly specialized. These overspecialized chairs may be bulky, large, and expensive. Bulky chairs may also be difficult to transport, carry, and store. Some chairs may be used more for their aesthetic features than their functionality. For example, some chairs are used to accent the style of a room or patio. Thus, users may need to buy multiple chairs for different environments and tasks.

DETAILED DESCRIPTION

[0047] The present disclosure describes various implementations of a foldable chair. The foldable chair can be put in a folded configuration or an unfolded configuration. The multiple configurations make the foldable chair convenient to store, transport, and use. In the folded position, the chair takes up much less space than a standard chair (e.g., a nonfoldable chair). The foldable chair is also easier to carry in the folded position. Additionally, the folded chair is less awkward to carry than a standard chair. The foldable chair is also made of lightweight components and materials (e.g., a plastic material) which reduce the chair's weight. Once a user is done transporting the foldable chair, the user can easily use the release tab to unlock the chair, as further described below. Once the chair is unfolded, the foldable chair can automatically lock into the unfolded position.

[0048] The foldable chair is also customizable to improve the experience and comfort of a user. For example, the foldable chair supports attachments such as a cup holder, book holder, and parasol or sun shade, where the cup holder and parasol can be adjustable (e.g., between different positions or orientations). Additionally, the foldable chair may have removable covers. The removable covers are made of a fabric (e.g., a mesh fabric, a cloth fabric, etc.). Thus, a user can remove and replace the cover if the fabric gets damaged. Additionally, the user can replace the fabric to personalize their chair. For example, a custom cover may include the logo of the user's alma mater, favorite sports team or have other images or insignia (e.g., a picture of the user's beloved family pet). Furthermore, the foldable chair has a seat back that can be adjusted to a number of reclined positions. The user can disengage a lock to adjust the seat back. For example, the user can lift the chair’s arm rests to disengage the lock, move the seat back backwards to recline, and reengage the arm rests to a frame of the chair to lock the reclined position of the chair.

[0049] Figure 1 and Figure 2 illustrate a front and back perspective view, respectively, of the foldable chair 100 in an unfolded configuration (e.g., a primary seating configuration). In some embodiments, the foldable chair 100 has a seat back 105, a seat bottom 115, front legs 135, and back legs 140. In some embodiments, the foldable chair 100 has a sled base (not shown). For example, the left front leg 135 may connect to the left back leg 140, and the right front leg 135 may connect to the right back leg 140. Similarly, the left front leg 135 may connect to the right front leg 140, and the right back leg 135 may connect to the left back leg 140. The connections between the front legs 135 and the back legs 140 may run along the supporting surface (e.g., the ground) to provide more support and balance for the foldable chair 100. In some embodiments, the seat back 105, seat bottom 115, front legs 135, and back legs 140 are made of a lightweight and durable material, such as carbon fiber or aluminum. The foldable chair 100 components can also, or alternatively, be made of wood, plastic, metal, wicker, or a composite. Overall, the durability of the foldable chair 100 allows the foldable chair 100 to support weights up to approximately 110-190 kilograms (kg), such as about 160 kg.

[0050] In some embodiments, the foldable chair 100 can have a pair of arm rests 205. The arm rests 205 can be removably attached to the seat back 105 and/or a first hinge 150. Alternatively, or in addition, the arm rests 205 may be attached to the seat bottom 115. The arm rests 205 can be made of fabric, plastic, rubber, wood, carbon fiber, metal, or a composite material. The arm rests 205 may also be made from a combination of these materials (e.g., fabric-covered wood). Regardless of the material, the arm rests 205 allow a user to position (e.g., support) his or her arms more comfortably while seated on the chair 100. Overall, the arm rests 205 may reduce the strain on the shoulder and back of a user by allowing the user to sit in a healthier position.

[0051] The seat back 105 and seat bottom 115 may have perforated surfaces. For example, the seat back 105 and seat bottom 115 may have a pattern of spaced holes 145 (e.g., regularly spaced holes) that have been punched, drilled, or otherwise created through the material (e.g., entirely through the thickness of the seat back 105 and/or seat bottom 115). The holes 145 may be of uniform size and shape, or they may vary in size and shape. In some embodiments, only a portion of the seat back 105 and seat bottom 115 are perforated surfaces. The repeating holes 145 in the seat back 105 and seat bottom 115 can be useful for a variety of purposes, such as allowing air to pass therethrough to keep the user cool when seated on the chair 100, allowing water to pass therethrough due to rain or a liquid spill, providing a decorative pattern, or reducing the weight of the foldable chair 100. In some embodiments, the one or more of the holes 145 may be connectors designed to allow attachments, accessories, or additions to be securely connected, as further discussed below.

[0052] The foldable chair 100 may additionally, or alternatively, have one or more (e.g., a pair of) top connectors 210, and one or more (e.g., a pair of) bottom connectors 215. In some embodiments, the top connectors 210 are built into the seat back 105 (e.g., at a top end of the seat back 105), and the bottom connectors 215 are built into the seat bottom 115 (e.g., at a front end of the seat bottom 115). The connectors 210, 215 improve the experience of a user by allowing the user to customize the foldable chair 100 according to his or her preferences. For example, these connectors 210, 215 allow a user to connect accessories to the seat back 105 and seat bottom 115 of the foldable chair 100. The connectors 210, 215 will be described in more detail below. In some implementations, the connectors 210, 215 can include openings or female shaped recesses that can receive a male shaped connector of one or more accessories described herein. In other implementations, the connectors 210, 215 can include male shaped connectors that can extend into openings or female shaped connectors of one or more accessories described herein.

[0053] Figure 3 and Figure 4 illustrate a front and back perspective view, respectively, of the foldable chair 100 in a folded configuration. In some embodiments, the front legs 135 and back legs 140 may be connected via the first hinge 150. Similarly, the seat back 105 and seat bottom 115 may be connected via a second hinge 310. Thus, the different components of the foldable chair 100 can be adjusted (e.g., rotated) independently of each other. The independent movement of the foldable chair 100 components allows the foldable chair 100 to be positioned in different configurations. For example, the foldable chair 100 can be put into an unfolded configuration by increasing the angle between the front legs 135 and back legs 140 and between the seat back 105 and the seat bottom 115. Similarly, by aligning the different foldable chair 100 components (e.g., the seat back 105, seat bottom 115, front legs 135, and back legs 140), the foldable chair 100 can be moved into a folded configuration. In some embodiments, the seat back 105, seat bottom 115, front legs 135, and back legs 140 are generally parallel when the foldable chair 100 is in the folded configuration. The folded configuration may reduce the size of the foldable chair 100 and make the foldable chair 100 easier to store and carry. For example, the folded configuration allows a user to carry a chair with only one hand. In some embodiments, the foldable chair 100 has a handle or shoulder straps, which makes the foldable chair 100 convenient to carry (e.g., with one hand or carried on the user’s back). Additionally, or alternatively, the foldable chairs 100 may be designed to be stackable while in either a folded or unfolded configuration.

[0054] In some embodiments, the foldable chair 100 can be locked in the folded or unfolded configuration to inhibit (e.g., prevent) the foldable chair 100 from unexpectedly folding or unfolding (e.g., when it is being carried, stored, or used). The foldable chair 100 may lock automatically when it reaches either the folded or unfolded configuration. In some embodiments, the foldable chair 100 has a release tag 305 that unlocks the position of the foldable chair 100. The release tag 305 may be a small, thin piece of material (e.g., fabric, leather, mesh, plastic, etc.) that is attached to the foldable chair 100 in a way that allows a user to easily pull the release tag 305.

[0055] In some embodiments, when a user pulls the release tag 305, it activates a mechanism that unlocks the foldable chair 100 and allows it to be folded or unfolded. For example, to unfold the unlocked foldable chair 100, the user may rotate the seat back 105 away from the seat bottom 115 until the seat back 105 locks into place. In some embodiments, the foldable chair 100 can be unfolded with only one hand. For example, the foldable chair 100 may have springs and dampers (not shown) which push the foldable chair 100 open. In some embodiments, the foldable chair 100 springs open when the release tag 305 is pulled or a button is pressed. Overall, the folding/unfolding process is efficient and simple.

[0056] Figure 5 illustrates a bottom view of the foldable chair 100. Similarly, Figure 6 illustrates a bottom view of the foldable chair 100 with a portion of the bottom cover removed. Thus, Figure 6 illustrates one embodiment of the locking mechanism 600. In some embodiments, the locking mechanism includes the release tag 305, one or more pull wires 605, and one or more spring-loaded pins 610. The release tag 305 may be connected to two pull wires 605. Each pull wire 605 may be connected to a spring-loaded pin 610. Thus, when a user pulls the release tag 305 the spring-loaded pins 610 may be pulled from their corresponding pin slots (e.g., to unlock the position of the chair 100, such as a folded configuration, and allow it to be moved into a different position, such as an unfolded configuration, and vice versa). In some embodiments, the foldable chair 100 had two sets of pin slots (not shown). For example, one set of pin slots may correspond to the folded configuration and a second set of pin slots may correspond to the unfolded configuration.

[0057] Figures 7 - 10 illustrate the foldable chair 100 with detachable covers 700, 710 or skins removably attached to the seat back 105 and the seat bottom 115, respectively. The detachable covers 700, 710 can be separate from each other (e.g., not form a single cover that goes over the seat bottom 115 and seat back 105). In some embodiments, detachable covers 700, 710 can be made from a variety of materials, including natural fabrics such as cotton, linen, bamboo, rattan, wicker, mesh, leather, tweed, and wool, as well as synthetic fabrics such as polyester, nylon, and spandex. The choice of material can depend on the desired look and feel of the detachable covers 700, 710, as well as the intended use and desired level of durability. For example, detachable covers 700, 710 made from a natural fabric such as cotton may be more breathable and comfortable to sit on, while detachable covers 700, 710 made from a synthetic material such as nylon, polyester webbing strips, and marine grade acrylic may be more durable and resistant to stains. Additionally, some detachable covers 700, 710 may be made from a combination of different materials, such as a cotton-polyester blend, to achieve the user’s desired properties. In some embodiments, the seat back cover 700 and the seat bottom cover 710 have additional padding and/or are weatherproof (e.g., waterproof and UV resistant). Furthermore, the detachable covers 700, 710 may allow the user to customize the foldable chair 100 with a desired design (e.g., logo, insignia, such as that of a favorite sports team or alma mater, etc.) and allow the user to easily change designs. Additionally, the detachable covers 700, 710 allow the user to easily repair a damaged or worn-out cover.

[0058] In some embodiments, each detachable covers 700, 710 has sleeve pockets. The sleeve pockets can extend over at least a portion of the seat back 105 and/or seat bottom 115. Alternatively, the sleeve pocket may cover the entire seat back 105 and/or seat bottom 115. In some embodiments, the detachable covers 700, 710 have openings for the top connectors 210 and bottom connectors 215. Thus, the connectors 210, 215 may be accessible (e.g., exposed, uncovered) when the detachable covers 700, 710 are attached to the foldable chair 100.

[0059] One or both of the detachable covers 700, 710 may have straps 715, 720 respectively, that connect the front of the detachable cover 700, 710 to the back of the detachable covers 700, 710. The straps 715, 720 may wrap around the seat back 105 or seat bottom 115 to attach the detachable cover 700, 710 to the corresponding portion of the foldable chair 100. In some embodiments, a strap 715, 720 may have a coupling member 705 that corresponds to a coupling element on the sleeve pocket of the detachable cover 700, 710. The coupling member 705 may be or include a magnet that corresponds to a magnetically receptive surface (e.g., the coupling element) on the back of a detachable cover 700, 710. Thus, a user may be able to easily attach and remove the detachable covers 700, 710. Alternatively, or in addition, the coupling member 705 may be a snap-fit fastener, hook and loop fasteners, a zipper, or a threaded fastener. Additionally, some embodiments, may use a combination of one or more of the coupling methods (e.g., magnet and snap fits).

[0060] For example, Figure 26 illustrates one embodiment of the foldable chair 100 with a detachable cover 2605 that has a zipper 2600. The zipper 2600 may be used to resiliently couple the detachable cover 2605 to the foldable chair 100. In some embodiments, the detachable cover 2605 includes the straps 715 with coupling members 705. Alternatively, some embodiments of the detachable cover 2605 may use a zipper as the only coupling element (e.g., some detachable covers may not have straps). Alternatively, or in addition, the zipper 2600 may be positioned down the middle of the detachable cover 2605 or on the top of the detachable cover 2605. In some embodiments, the detachable cover 2605 may have more than one zipper (e.g., a zipper on each side) or one continuous zipper that is located across three sides of the detachable cover 2650 (e.g., the zipper is on a first side, the top, and a second side). Though Figure 26 shows the zipper 2600 on the side of detachable cover 2605 for the seat back 105, one of skill in the art will recognize that the detachable cover 710 for the seat bottom 115 can similarly have a zipper that may be used to attach the detachable cover 710 to the seat bottom 115.

[0061] Alternatively, or in addition, the coupling member on the strap 715, 720 may attach to a hole 145 of the perforated surface of the foldable chair 100. Figures 11 - 12 illustrate the foldable chair 100 with detachable covers 700, 710 that have coupling members 1100 that attach (e.g., in a press-fit or friction- fit manner) to the perforated holes 145. For example, the coupling member 1100 may be the projection portion of a snap-fit coupling while the hole 145 may be the recess portion of the snap-fit. Thus, a user may easily push the coupling member 1100 into the hole 145 (e.g., the coupling element) to securely attach the detachable cover 700, 710 to the foldable chair 100. Similarly, the user may easily pull the coupling member 1100 from the hole 145 to remove the detachable cover 700, 710. Alternatively, or in addition, the coupling member 1100 may be a magnet that corresponds to a magnetically receptive surface corresponding to one or more of the holes 145. Furthermore, the coupling member 1100 may be a snap-fit fastener, a hook and loop fastener, or a threaded fastener. Though FIGS. 11-12 show the coupling members 1100 attached to the straps 1105 of the detachable cover 700 for the seat back 105, one of skill in the art will recognize that the detachable cover 710 for the seat bottom 115 can similarly have straps with coupling members 1100 that couple to perforated holes 145 in the seat bottom 115. In another implementation, the cover 710 for the seat bottom 115 can have coupling members 705 attached to its straps 720. In still another implementation, the detachable cover 710 for the seat bottom 115 can have straps with coupling members 1100 that couple to perforated holes 145 in the seat bottom 115, and the detachable cover 700 for the seat back 105 can have straps 715 with coupling members 705.

[0062] Figures 13 illustrate one embodiment of the foldable chair 100 with detachable covers 700, 710 that have coupling members 2425 that attach to (e.g., elastically or resiliently couple to) coupling elements 2405 on the seat back 105 and seat bottom 115. The coupling members 2425 can resiliently couple to corresponding coupling elements 2405 on the surface of the chair frames (e.g., the seat back 105 and/or seat bottom 115). In some embodiments, the detachable covers 700, 710 have one to six elastic coupling members 2425, such as four. Similarly, in some embodiments, the seat bottom 115 and seat back 105 have one to six coupling elements 2405, such as four. In some embodiments, the elastic coupling members 2425 are elastic hoops and the coupling elements 2405 are knobs or tabs (e.g., protrusions). Thus, to couple the detachable covers 700, 710 to the foldable chair 100, a user may wrap the elastic hoops around the corresponding knobs, which allows the detachable covers 700, 710 to be pulled taut. In some embodiments, the foldable chair 100 may use a combination of coupling methods. For example, the seat back cover 700 may use magnetic clasps that attach to the seat back cover 700 while the seat bottom cover 710 uses snap-fit coupling members that attach to a hole 145 of the foldable chair 100. However, any combination of the coupling members and coupling elements described herein may be used to attach the detachable covers 700, 710 to the foldable chair 100.

[0063] In some embodiments, the seat back cover 700 and seat bottom cover 710 can be a single continuous cover that attaches to both the seat bottom 115 and seat back 105. The single continuous cover may have one or more sleeve pockets. The one or more sleeve pockets can extend over at least a portion of the seat bottom 115 and/or the seat back 105. The single continuous cover can have one or more coupling members, such as coupling members 705, 1100, 2425 described above.

[0064] Figures 14 illustrate a bottom perspective view of two embodiments of the arm rest 205 of the foldable chair 100. In some embodiments, the arm rest 205 may have a connector 1405, a recessed area 1410 or 1420, and a sliding slot 1415. The sliding slot 1415 may be used to rotate the arm rest in relation to the first hinge 150 and the front and back legs 140 (see Figure 4). In the illustrated examples, the connector 1405 is a male shaped element that can couple to an opening or female shaped connector of an accessory (e.g., a cup holder). In other implementations, the connector 1405 can alternatively be a female shaped element that can couple to a male shaped connector of an accessory.

[0065] Furthermore, in some embodiments, the connectors 210, 215, and 1405 may be used to attach a variety of detachable accessories to the foldable chair 100. For example, the foldable chair 100 can be customized with one or more of the following: parasols or sun shade, Bluetooth speakers, lights, small tables, GPS trackers, book holders, hooks (e.g., for holding a bag or other item), or battery packs. Overall, the connectors 210, 215, and 1405 allow the foldable chair 100 to be easily customized to a user’s preference. The connectors 210, 215 and 1405 may use a friction fit, snap fit, or magnets to couple to the accessories. Additionally, in some embodiments, the connectors 210, 215 and connector 1405 may use screws, latches, or buckles to couple to accessories. The connectors 210, 215, and 1405 may also, or alternatively, use keyed connectors (e.g., key-slot connectors) that lock into place when the corresponding connectors of the accessories are inserted in the correct orientation. In some embodiments, the connectors 210, 215, and 1405 use a combinations of attachment methods (e.g., a magnetic friction fit). Additionally, the connection between the foldable chair 100 and the accessories may be dynamic or static. For example, some accessories may be adjusted (e.g., in orientation or position) after they have been connected to the foldable chair 100.

[0066] Figure 15 illustrates a cup holder 1500 accessory for the foldable chair 100. The cup holder 1500 may a main body 1505 with a coupling member 1510 for securing the cup holder 1500 to the foldable chair 100. The main body 1505 may have a circular opening for holding a standard-sized cup or bottle. In some embodiments, the cup holder 1500 has a rotating wine glass holder 1515, which can securely hold a wine glass (e.g., the wine glass holder 1515 has an opening that receives a stem of a wine glass therein). The wine glass holder 1515 can rotate 360 degrees. In some embodiments, a user can rotate the wine glass holder 1515 into a closed position 1500A when storing the cup holder 1500 and into an open position 1500B when using the wine glass holder 1515. The cup holder 1500 may be made of lightweight and durable materials that can withstand the weight of a cup or wine glass. For example, the cup holder 1500 may be made of metal, plastic, composites, or any other suitable materials. The main body 1505 of the cup holder 1500 may also have a mesh body. The mesh body may allow for easy cleaning of the cup holder, as any spills or debris can simply be brushed or rinsed away. The mesh body may be made of a flexible and durable material, such as a stainless steel, fabric, or plastic mesh. Thus, the cup holder 1500 may be a convenient and practical accessory for users who enjoy drinking while sitting in the foldable chair 100.

[0067] In some embodiments, the accessories have a protruded area that corresponds to the recessed area 1410 of the arm rest 205. For example, the coupling member 1510 may be placed on the protruded area. Alternatively, or in addition, the recessed area 1420 may extend until the end of the arm rest 205 to create a generally planar or flat surface for the coupling member 1510 of the accessories. In some embodiments, the recessed area 1420 may allow the attached accessory to rotate while it is attached to the foldable chair 100. For example, a user may rotate the cup holder 1500 into a closer or further position while it is attached (e.g., adjust the position of the cup holder 1500 between one where the main body 1505 is aligned and in front of the arm rest 205 and a position where the cup holder 1500 is not aligned and offset to the side, such as offset laterally, relative to the arm rest 205).

[0068] Figure 16 illustrates a parasol 1600 accessory or sun shade for the foldable chair 100. The parasol 1600 may be used to provide shade and protection from the sun and other elements, such as rain. In some embodiments, the parasol 1600 is a portable and expandable parasol that has a canopy 1615 that can be mounted on a joint 1605 (e.g., a ball joint). The canopy 1615 may be made of a weather-resistant material such as nylon or polyester. Alternatively, or in addition, the canopy 1615 may be made of any natural or synthetic material listed above. The joint 1605 may allow the parasol 1600 to rotate 360 degrees along the primary elongated axis (e.g., the axis extending along the length of the supporting rod 1610, which is parallel to the ground when the parasol 1600 is standing upright). Furthermore, the joint 1605 may allow the parasol 1600 to rotate 270 degrees or more along the secondary axis (the axis that is perpendicular to the primary elongated axis). Advantageously, the joint 1605 allows the user to adjust the parasol to provide shade and protection at various angles.

[0069] In some embodiments, the parasol 1600 can be folded for easy storage and transportation. For example, Figure 17 illustrates an embodiment of the parasol frame 1700 that is collapsible. The parasol frame 1700 may be made of metal, such as spring steel or aluminum. Alternatively, or in addition, the parasol frame 1700 may be made of plastic or a composite. The parasol 1600 may have a tensioner 1710 that forces the parasol frame 1700 open. For example, the tensioner 1710 may have an elastic fastener that connects the tensioner 1710 to a coupling member on the canopy 1615. In some embodiments, the tensioner 1710 may hold the parasol frame open in adverse weather conditions.

[0070] Figure 18 illustrates a handle 1620 that is configured to receive a portion of the supporting rod 1610 in a storage groove 1815 when the parasol 1600 is folded. The handle 1620 may also, or alternatively, have an attachment trigger 1805 to separate the ball joint 1605 from the handle 1620. For example, the attachment trigger may release a spring-loaded locking pin within the handle 1620 that unlocks the ball joint lock 1810. Thus, a user may break down the parasol 1600 into multiple parts.

[0071] Figure 19 illustrates a back perspective view of the foldable chair 100 that has the parasol 1600 attached. More specifically, the supporting rod 1610 has been inserted into the top connector 210.

[0072] In conclusion, the customizable foldable chair 100 provides a convenient and versatile solution for outdoor seating, comfort, and shade. The foldable chair 100 and its accessories (such as the parasol 1600 and cup holder 1500) can be easily collapsed and stored in a compact form, making the foldable chair 100 ideal for use at the beach, on a patio, or in other outdoor or indoor settings. The foldable chair 100 is sturdy and comfortable, and the accessories may be conveniently attached in a secure manner so that the connected accessory is able to withstand windy and adverse weather conditions. Thus, the foldable chair 100 may provide reliable shade and protection from the sun and other elements, as well as entertainment and comfort. [0073] Figure 20 illustrates a perspective view of the foldable chair 2000 in an unfolded configuration (e.g., a primary seating configuration). In some embodiments, the foldable chair 2000 has of a seat back 105, a seat bottom 115, a hinge mechanism 125, front legs 135, and back legs 140. The seat back 105 has a seat back frame (not shown) and a seat back fabric 110. The seat back fabric 110 can resiliently couple to the seat back frame in a taut configuration. The stretched seat back fabric 110 creates and/or defines the surface of the seat back 105. Similarly, the seat bottom 115 has a seat bottom frame (not shown) and a seat bottom fabric 120. The seat bottom fabric 120 can also resiliently couple to the seat bottom frame in a taut configuration. The stretched seat bottom fabric 120 creates and/or defines the surface of the seat bottom 115. The seat’s frame and fabric will be discussed in greater detail below.

[0074] The seat back 105, seat bottom 115, front legs 135, and back legs 140 each attach to different portions of the hinge mechanism 125. For example, the front legs 135 and back legs 140 are attached, via the hinge mechanism, to the left and right side of the seat bottom frame and seat back frame. Thus, the different foldable chair components can be adjusted (e.g., rotated) independently of each other. The independent movement of the foldable chair components allows the foldable chair 2000 to be positioned in different configurations. For example, the foldable chair can be put into a low, middle, or high vertical position by adjusting the angles of the front legs 135 and back legs 140. However, the chair 2000 can be adjusted between more or fewer positions than this (e.g., a plurality of different height positions, such as 2 or more, 3 or more, 4 or more, 5 or more different heights, etc.). The chair 2000 can also be put into a reclined position by adjusting the angle of the seat back 105 relative to the seat bottom 115. In some embodiments, the seat back 105 has a position lock that prevents the seat back 105 from being moved when the position lock is engaged. In some embodiments, the position lock is disengaged a hinge mechanism (e.g., the hinge mechanism may be pulled or actuated to disengage the position lock). Alternatively, or in addition, the position lock may be disengaged via the release tag 305 (see Figure 9). In some embodiments, the user may disengaged the position lock by lifting or lowering one or more arm rests. For example, the arm rests may be connected to one or more pull wires (not shown) that are connected to one or more spring-loaded pins. Lifting the arm rests may pull the spring-loaded pins from their corresponding pin slots to unlock the position seat back 105. Furthermore, by aligning the different foldable chair components (e.g., the seat back 105, seat bottom 115, front legs 135, and back legs 140) the foldable chair can be moved into a folded configuration (see e.g., FIG. 3). The foldable chair’s 2000 different configurations will be described more fully below. [0075] In some embodiments, the foldable chair components each have multiple connection points with the hinge mechanism 125. For example, the seat back 105 can connect to the hinge mechanism 125 through a left connection point and a right connection point. Additionally, in some embodiments, the seat back 105, seat bottom 115, front legs 135, and back legs 140 are made of a lightweight and durable material, such as carbon fiber or aluminum. The foldable chair components can also be made of wood, plastic, metal, or a composite. Overall, the durability of the foldable chair 2000 allows the chair 2000 to support weights up to approximately 110-185 kilograms (kg), such as about 160 kg.

[0076] The foldable chair 2000 has two or more vertical positions. In other words, the height of the seat bottom 115 above a support surface 905 (e.g., ground surface) can be adjusted by the user. Figures 21A, 21B, and 22 illustrate three of these vertical positions. Figure 21A illustrates a side view of the high vertical position 900A. When the foldable chair 2000 is in the high vertical position 900A, the top of the seat bottom 115 can in one implementation be approximately 40 cm - 52 cm above the support surface 905, such as about 45 cm. As seen in Figure 21 A, the high vertical position 900A may be used in connection with a table. More specifically, the high vertical position 900A puts the user at a comfortable height from a table’s surface while giving enough room for a user’s legs to slide underneath the table. Additionally, the high vertical position 900A may be the most comfortable position for tall users.

[0077] To put the foldable chair 2000 in the high vertical position 900A, the angle between the front legs 135 and back legs 140 is reduced. More specifically, the angle between the front legs 135 and back legs 140 is approximately 55° - 65°, such as about 59°. In some embodiments, the range of the recline angle of the seat back 105 may be restricted in the high vertical position 900A to prevent the foldable chair 2000 from tipping over. In other embodiments, the seat back 105 is locked in a single position when the chair is in the high vertical position 900A. However, in some embodiments, the range of the recline angle is not restricted in the high vertical position 900A.

[0078] Figure 21B illustrates a side view of the middle vertical position 900B. In the middle vertical position 900B, the top of the seat bottom 115 can in one implementation be approximately 32 cm - 45 cm above the support surface 905, such as about 40 cm above the support surface 905. In the middle vertical position 900B, the angle between the front legs 135 and the back legs 140 is approximately 65° - 120°, such as about 90°. In some embodiments, the range of the recline angle of the seat back 105 in the middle vertical position 900B may be greater than that of the chair 2000 in the high vertical position 900A, but can be restricted to prevent the foldable chair 2000 from tipping over. In other embodiments, the seat back 105 is locked in a single position when the chair is in the middle vertical position 900B. However, in some embodiments, the range of the recline angle is not restricted in the middle vertical position 900B.

[0079] Figure 22 illustrates a side view of the low vertical position 1000. In the low vertical position 1000, the top of the seat bottom 115 can in one implementation be approximately 15 cm - 35 cm above the support surface 905, such as about 30 cm above the support surface 905. In the low vertical position 1000, the angle between the front legs 135 and the back legs 140 is approximately 110° - 155°, such as about 132°. In some embodiments, the recline angle of the seat back 105 is not restricted in the low vertical position 1000, and can be greater than that of the chair 2000 in the high and middle vertical positions 900A, 900B. In other words, the seat back 105 can recline to a generally horizontal position. In some embodiments, the seat back 105 can recline to a negative angle (e.g., a position past horizontal where the user’s head is place below his chest). Overall, the low vertical position 1000 allows a user to relax by sitting in a reclined position (e.g., while outdoors, such as at the beach, at the park, while camping, etc.).

[0080] Figure 23 illustrates one embodiment of a foldable chair 2000 with a head rest 2905 and footrest 2910. In some embodiments, the head rest 2905 attaches to both top attachment points or connectors 210. Similarly, the footrest 2910 can be attached to both bottom attachment points or connectors 215. Having an accessory attached to more than one attachment point improves the stability and strength of the connection. Thus, the head rest 2905 and footrest 2910 will remain attached even under a significant load (e.g., 20 - 50 kg). However, in some embodiments, a head rest or footrest can be attached to the foldable chair 2000 using a single attachment point.

[0081] In some embodiments, the foldable chair 2000 also has attachment slots 2915. The attachment slots 2915 can resiliently couple to chair accessories. In some embodiments, the attachment slots 2915 are positioned on, or defined in, the side of the arm rests 205. The attachment slots may also be positioned on the top of the arm rests 205 or on the side of the seat bottom 115 or seat back 105. In another implementation, the foldable chair 2000 has one or more attachment points located on the bottom of the arm rests 205. Additionally, the attachment points and slots may be used while the foldable chair 2000 is in any configuration. In some embodiments, the attachment slots 2915 connect to the chair accessories using magnets, slots and tabs, a snapping mechanism, a friction fit, a screwing mechanism, or a combination of these methods. Though FIGS. 20-23 show the foldable chair 2000, one of skill in the art will recognize that the foldable chair 100 may have similar features and advantages, such as two or more vertical positions. [0082] The features and advantages described above can also be applied to a foldable table. Figures 24 A - 25B illustrate a foldable table 3100A-3100D that has a hinge mechanism 3105 with a rotatable knob, and a pair of front legs 3110 and a pair of rear legs 3115. The hinge mechanism has all the functionality of the hinge mechanisms (e.g., 125, 1900A, 1900B, 2100, 2300A, and 2300B) described above. For example, in some embodiments, the hinge mechanism can have one or more pins with corresponding slots, and a rotatable knob that adjusts the position of the one or more pins and the corresponding slots. The hinge mechanism 125 may also use one or more gears or a mechanical linkage assembly. In some embodiments, a user actuates the hinge mechanism by axially pulling on the rotatable knob to unlock the hinge mechanism and then rotates the knob to select a new configuration. When the user stops axially pulling the rotatable knob, the hinge mechanism automatically locks back in place.

[0083] In some embodiments, the user can configure the table surface to have a vertical height of between 10 - 75 cm, such as 40 cm. In other words, the user can select any vertical height between the table’s minimum and maximum height. In other embodiments, the foldable table has two or more discrete positions. For example, the table may have a high vertical position 3100A, middle vertical position 3100B, low vertical position 3100C, and folded position 3100D. In the folded position 3100D the first axis of the table (e.g., the axis that is perpendicular to the hinge axis) is generally aligned with the pair of front legs and the pair of rear legs. Additionally, in the unfolded configurations (3100A-3100C) the legs are not generally aligned with the first axis of the table.

[0084] In some embodiments, the foldable table 3100A-3100D also has a removable fabric (e.g., similar to the fabric 110, 120) that couples to the table surface frame (not shown). Thus, like the foldable chair 2000 the foldable table 3100A-3100D allows a user to easily customize and/or repair the table. Overall, the foldable chair and table are easily used, transported, and stored.
