The present invention relates to convertible chairs, especially convertible chairs for outdoor use and convenient storage.
Leisurely enjoying the outdoors is an ideal setting for relaxation. The best outdoor experiences for many involve a combination of comfort, cleanliness, spontaneity, complacency and affordability. Unfortunately, no matter what climate someone lives in, the elements constantly erode these elusive and expensive qualities of outdoor furniture. The rain, dirt, sun, snow, leaves, pets, grime, dust, dew, salt, bugs, mold, mildew, critters, bird droppings, and of course the most destructive enemy, UV deterioration, destroy outdoor furniture if it is not protected. Furthermore, most outdoor chairs are not very comfortable nor do they have all of the features of an indoor furniture as many manufacturers focus on durability while giving up comfort and functionality.
Provided herein are convertible chairs that can be used and stored outdoors. The convertible chairs are comfortable and can include a wide range of functionalities and features, and can be converted into a box or table that encloses elements that are typically destroyed over time by the elements outdoors.
In some aspects, a convertible chair comprises a first side portion (e.g., a right side portion), a second side portion (e.g., a left side portion), a seat portion extending between the first side portion and the second side portion, the seat portion optionally forming a bottom portion of the box when the convertible chair is in a closed box configuration), a back portion extending between the first side portion and the second side portion, and a top portion hingedly coupled to the back portion on a first edge and hingedly coupled to a front portion on a second edge. The convertible chair is configured to convert from a closed box configuration to an open chair configuration. It should be appreciated that a closed box configuration can comprise one or more gaps or openings, for example, to allow air flow from beneath the convertible chair. In some aspects, each of the first side portion, second side portion, seat portion, back portion, top portion, and front portion can comprise separate pieces coupled or attached to one another. In some aspects, the first side portion, second side portion and seat portion can be a single piece. In some aspects the convertible chair comprises a chair frame that includes the first and second side portions, the seat portion, and the back portion. In some aspects, a convertible chair is a recliner with a recliner frame coupled to the chair frame. Legs can extend from a lower surface of the chair frame. A cover that comprises the top portion and front portion can be deployed from and retracted into a pocket of the back portion. Additionally or alternatively, a cover that comprises the top portion and front portion can be rotated or pivoted up and above (or even partially or fully behind) the back portion without being retracted into a pocket.
The top portion and front portion can be adjustable from a box configuration to a folded configuration to a sunshade configuration. The top portion and front portion can be parallel to one another with the front portion is front of the top portion in the folded configuration. The top portion and the front portion can form an angle of between 45 and 170 degrees and the top portion and the back portion form an angle of between 120 and 225 degrees in the sunshade configuration. The top portion can form an angle of about 90 degrees with each of the back portion and the front portion, with the front portion positioned in front of the back portion, in the box configuration.
The back portion can comprise a pocket sized and dimensioned to receive at least a portion of the top portion (e.g., at least 70%, at least 80%, at least 90% or 100%). The pocket can be sized and dimensioned to receive at least a portion of the front portion (e.g., at least 70%, at least 80%, at least 90% or 100%). The pocket can be sized and dimensioned to receive at least 70%, at least 80%, at least 90% or 100% of each of the top and front portions. In some aspects, the pocket can house a retraction and deployment mechanism, for example, comprising two parallel rack and pinion pairs operatively coupled to one another through a synchronizing axle.
A set of legs (e.g., 1, 2, 3, 4, 5, or more legs) can extend downwardly from the lower surfaces of the seat, side, back or other portions. In some aspects, each leg of the set of legs can comprise at least one of a wheel and a caster to allow for easy movement of the convertible chair between different locations. In some aspects, the at least one of a wheel and a caster can comprise a stopper, a lock, or a brake (e.g., a locking caster or a braking caster).
In some aspects, the convertible chair can comprise a reclining chair. The back portion can be configured to recline from a first configuration wherein the back portion and the seat portion form an angle of about 90 degrees to a second configuration wherein the back portion and the seat portion (or ground the chair is placed on) form an angle of between 115-180 degrees. It is contemplated that the back portion can be locked at multiple positions relative to the ground. The seat portion can be coupled to an adjustable foot rest. A recliner frame can be coupled to each of the foot rest and the back portion such that an adjustment of an angle of the back portion relative to the seat portion or ground causes an adjustment of an angle of the foot rest relative to the seat portion or ground. In some aspects, an adjustment of the foot rest causes an adjustment of the back portion.
The first side portion can comprise a first upper armrest panel that is hingedly coupled to a side wall portion of the first side portion. The first upper armrest panel can be adjustable about 180 degrees from a closed configuration to an open configuration. The second side portion can comprise a second upper armrest panel that is hingedly coupled to a side wall portion of the second side portion. The second upper armrest panel can be adjustable about 180 degrees from a closed configuration to an open configuration. The open configuration can be useful in providing a larger surface for placement of an arm, a drink, food, a phone, or any other item.
One or more sets of magnets can be provided along various portions of the convertible chair (internally to a panel or portion, or on an outer surface of the panel or portion) that can help maintain the convertible chair or portion thereof in a selected configuration. For example, a set of magnets can be positioned within the first and second side portions and the front portion to help maintain the convertible chair in the closed box configuration. As another example, where a side portion is hingedly coupled to an upper armrest panel such that the upper armrest panel is adjustable about 180 degrees from a closed configuration (where the upper armrest panel is positioned on top of the side portion) to an open configuration wherein the upper armrest panel is parallel to and adjacent an upper surface of the side portion), a set of magnets may be provided on the upper armrest panel and side portion to help maintain the upper armrest panel in the closed configuration when a larger surface is not needed.
Other advantages and benefits of the disclosed compositions and methods will be apparent to one of ordinary skill with a review of the following drawings and detailed description.
The novel features of the disclosure are set forth with particularity in the appended claims. A better understanding of the features and advantages of the present disclosure will be obtained by reference to the following detailed description that sets forth illustrative embodiments, in which the principles of the disclosure are utilized, and the accompanying drawings of which:
Provided herein are convertible chairs that can be used and stored outdoors. The convertible chairs are comfortable and can include a wide range of functionalities and features, and can be converted into a box or table that encloses elements that are typically destroyed over time by the elements outdoors. In some aspects, the chairs can be comparable in comfort to the most luxurious of indoor recliners, while offering multiple features which adapt it perfectly for outdoor use. The chair can be easily turned into at least one of a table and a box, which allows it to be stored and keep it protected from the elements, especially the internal cushioning components. The construction of the chair and the tightness of the closure of the chair into a box in some embodiments can inhibit most elements from reaching the cushions of the chair when it is being stored. Additionally, the inventive convertible chairs are very comfortable and can have any and all the features of an indoor chair or recliner. In some embodiments, the chair can have a sunshade component to protect its user from the harsh rays of the sun, and can have multiple sitting positions available. An innovative built-in protective cover component can comprise a top portion and a front portion (the top portion forming the top when the convertible chair is in a box configuration; the front portion forming the front when the convertible chair is in a box configuration). The front portion can rotate relative to the top portion and maintain or lock in place in different configurations to act as a sunshade or allow for full sun exposure, when desired, while the top portion can rotate relative to the back portion and lock in place in different configurations to act as a top of a box, a seat back portion, a headrest portion, or stowed away in a pocket of the back portion. For example, one or more torque hinges or locking hinges may be provided between one or more of the front portion and top portion, and the top portion and the back portion (or any other components), which can reduce or eliminate the risk of an inadvertent closing or moving of the cover component. It is contemplated that the chair can be operated with a single hand, and can fold-to-close, which can effortlessly seal away or otherwise cover the cushions and arm rests to protect them until the next use as a chair. When the chair is closed it can form a box shape which can be easily stored or can also function as a table. In some embodiments, a lock may be provided, for example, to lock a front portion of the chair to a bottom or other portion of the chair when in a box configuration. In some embodiments, when the convertible chair is closed, all the contact surfaces of the chair are substantially protected from the elements while allowing free airflow from underneath (e.g., via a gap formed between the front portion, side portions, and a footrest or seat portion or via vent holes) to prevent moisture build-up. When open, some convertible chair positions range from sitting up (e.g., with the back portion substantially orthogonal to the seat portion or ground) to fully reclined sunbathing or sleeping under the stars (e.g., with the back portion substantially forming a 180 degrees angle with the seat portion), and anywhere in between (e.g., the back portion and seat portion forming an angle of between 90-180 degrees, between 95-175 degrees, between 120-165 degrees). Viewed from another perspective, it is contemplated that a convertible chair of the inventive subject matter can have a back portion that is adjustable relative to the seat portion or ground the chair is placed on to form an angle of between 90-180 degrees. Viewed from another perspective, it is contemplated that a convertible chair of the inventive subject matter can have a back portion that is adjustable relative to the seat portion or ground it is placed on to at least 2, at least 3, at least 4, or at least 5 lockable positions forming different angles of between 90-180 degrees. Never before has clean outdoor comfort been so effortless.
Embodiments described herein provide an outdoor convertible chair, optionally a recliner chair, which can be positioned into one or more chair configurations and can be compacted into a box or table configuration. The embodiments described herein can be a single seat chair, or a larger double, triple, quadriple, quintuple, etc. seat chair (e.g., a loveseat or couch), all of which can be turned into a box or table. Thus, it should be appreciated that the term “chair” can include a multi-seat furniture item that several people can sit on, as well as a single seat furniture item. When the chair is in the box or table position the cushions and other components/surfaces of the chair that are entirely enclosed or substantially enclosed (e.g., enclosed from the top and sides and substantially enclosed from the bottom) are advantageously protected from the elements. Additionally, in some embodiments, in the closed position air can freely flow through portions of the chair from underneath the chair preventing moisture build-up.
The convertible chairs of the inventive subject matter have several advantages over known chairs, including some or all of the following advantages.
Reduction of damage: the damage the elements cause to outdoor furniture can drastically reduce their lifespan and therefore require more frequent replacement. The inventive subject matter reduces the exposure time by allowing contemplated chairs to be easily converted with one hand into a box for storing it (and optionally other items) and protecting it from the elements. This ease of protection is much less effort and expense of the traditional outdoor furniture which must be covered by furniture covers, frequently replaced in whole or in part (e.g., cushions), or dragged inside after every use.
Spontaneity: lack of spontaneity is one of the largest drawbacks to outdoor furniture usability. Enjoying the outdoors is a favorite setting for many people. But the elements cause the opportunities for outdoor furniture usage to be intermittent. When free time coincides with nice weather the opportunity is hopefully acted upon. However, without constant maintenance, outdoor furniture requires a decent amount of preparation before usage. Removing unwieldy and unattractive covers, retrieving cushions from protective deck boxes, or cleaning, any of these can diminish the user friendliness of outdoor chairs. The inventive subject matter eliminates or reduces the need for such unattractive covers, movement of cushions to and from separate protective deck boxes, and cleaning, and provides for a chair that can be converted from a box to a chair, or from a chair to a box, with ease (e.g., with a single action of lifting the protective cover, with a single action of closing the protective cover, by lifting the protective cover by a handle, allowing it to fold and retract into a pocket of the chair, by lifting the folded protective cover out of the pocket, allowing it to unfold and close with the top portion over the seat and side portions and the front portion in front of the seat and side portions).
Comfort: Few would describe outdoor seating comparable in comfort to indoor seating. Mainly because maintaining plush outdoor cushions and upholstery is time consuming and expensive. Therefore, a compromise is made by reducing comfort in exchange for durability. The invention dramatically reduces this concern, allowing more delicate and comfortable seating surfaces, which can be stored away within the chair when in a closed box configuration.
Aesthetics: the convertible chairs described herein offer improved aesthetics in several ways. In the closed position, the chair offers an attractive built in cover, which is an improvement upon a durable soft cover. With the ease of protection, the reduced time interval of exposure to the elements allows the vulnerable surface areas to stay more pristine and attractive, and for more aesthetically pleasing materials to be used.
After reading this description it will become apparent to one skilled in the art how to implement the invention in various alternative embodiments and alternative applications. However, all the various embodiments of the present invention will not be described herein. It is understood that the embodiments presented here are presented by way of an example only, and not limitation. As such, this detailed description of various alternative embodiments should not be construed to limit the scope or breadth of the present invention as set forth below.
An edge of the back rest 6 by way of one or more hinges 60 or other attachment mechanisms can be coupled to a sunshade 2 which also functions as the front lid or cover when the convertible chair is in its closed box or table configuration. When the cover (top portion/back rest 6 and front portion/sunshade 2) is in it's folded out open position, the sunshade 2 can be positioned above the user's head and protect the user's face and head from the harmful rays of the sun. The sunshade 2 can fold in conjunction with the back rest 6 such that the sunshade 2 closes/serves as a front portion of the box while the back rest 6 closes/serves as a top portion of the box when the convertible chair is in a closed box configuration. The sunshade 2 and back rest 6 can form a seal with the upper edges 22(a), 22(b) (or arm rest portions) and front edges 23(a), 23(b) of the side portions 12(a), 12(b). The seal can be formed or maintained, for example, via one or more magnetic door catches. In some embodiments, a sealing device such as a silicone or rubber seal strip may be provided to ensure internal components of the chair are protected from the environment and weather changes. In some embodiments, the convertible chairs described herein can be weatherproof or weather resistant, such that the convertible chairs can be left outside in the rain or snow in a closed box configuration without damaging (or substantially damaging) the chair. In some embodiments, air can flow through from under the seat through the upholstery and cushions, for example, as shown by arrow A. The hinges of convertible chair 10, for example, the hinges coupling back rest 6 and sunshade 2 can be torsion hinges so that the shade can be fixed at various angles.
The convertible chair 10 has a seat portion 20 that can be coupled to the back rest 6 which can be adjusted into an upright or reclined position. Seat portion 20 can be directly coupled to the back rest via a hinge assembly, or can be indirectly coupled to the back rest (e.g., via a hinge or other coupling assembly and the back portion of the convertible chair) Adjustably coupled to the seat portion 20 can be a foot rest 15 which can be folded in as seen in
The chair can also have legs 14(a), 14(b), 14(c) and 14(d) which can be attached to the front and back lower end of each side portion, or along any other suitable portion of the chair. In an alternate embodiment of the chair the foot rest 10 can tuck all the way under the seat so that it lays parallel to and under the seat when it is tucked up. When the foot rest 10 is in this position the feet of the chair can be longer giving the chair longer legs.
The recliner can have a cushion 7 as described above which extends over a first surface of the back rest 6 onto a first surface of the seat portion. In a preferred embodiment this cushion is comprised of three sections with seams between each allowing the cushion 7 to follow the angles of the chair when it is placed in its various positions including being upright, reclined or folded into a box. The upper portion of the cushion is attached to the upper portion of the back rest 6 by way of a “Footman's loop”. Referring to
In opening this embodiment of the chair, the reverse can be achieved, for example, by doing the following: First, the combined sunshade 2 and back rest 6 can be lifted together, one or both of the finger pulls can be pulled with as little as one finger to lift the seat back to the open position. At this point the user can sit in the chair as is with sunshade lid articulated in the “sunshade” position. Second, before sitting the sunshade lid can be left in the sunshade position, or folded back, out of the way, into a “parallel position” with the back rest. Sunshade 2 can be attached with a position/torque/friction hinge or other mechanism so the sunshade's angle can be articulated in a multitude of positions.
When the sunshade lid 2 reaches the lower chair to complete the closure, a magnet latch, or other type of latch, catch or locking device can hold the sunshade lid in the closed position. When opened the armrests 12(a) and 12(b) can be folded open to double the surface area. The arm rests can have butler hinges to allow them be folded open and closed. Before closing, the armrests are folded inward to narrow the width of the closed chair and to seal off the user's contact surfaces from the elements. The entire chair can be closed into a box and held shut by internal magnets. These magnets can be placed on the inside surfaces of the portion of the chair which turns into a box to hold it together so that it does not pop open. The placement of these magnets can vary depending on the size and style of the chair.
The top portion 120 and front portion 105 can be lifted together to a configuration where they are parallel with the front portion 105 in front of the top portion 120, and then they can slide into the pocket 140 at the back of the chair when the chair is in its open seating position. Thus, the pocket can have a front to back length that is greater than a combined thickness of the top portion 120 and the front portion 105. The cover can then slide (retract) vertically on internal guides down into a rectangular pocket 140 behind the back cushion of the chair, thus concealing the entire retracted cover under a narrow door 135 extending along the width of the rear top of the chair. In some aspects, the narrow pocket 140 lid 135 can open to a 90° (or other) angle when open, then closes to be parallel with the armrests, and perpendicular to the retracted cover, giving the appearance when closed of a consistent top with the adjacent armrests. Double track guides can be used to guide the motion of the retracting and extending cover panels (top portion 120, front portion 105) into and from the pocket. The top portion 120 and front portion 105 can be connected together with a piano hinge or other type of hinge (e.g., torque/friction/torsion/position hinge). Connected to the track guides 150 are shuttles which slide vertically. The shuttles have attached hinges which connect to the rear of the cover to allow a controlled hinging of the upper cover from the vertical retraction position to the horizontal cover position.
In an embodiment of the chair it can have wheels attached to the bottom surface or feet so that the chair can be easily moved. The chair can also come with a locking mechanism so that it can't be opened or used unless unlocked.
In some embodiments, the material of the chair may be a vinyl or PVC material, such as 18-ounce vinyl-coated polyester. The material may be mildew and UV resistant to prolong the life of the cover and prevent fading or mildew buildup on the outer surface of the seat cushions as well as between the interior surfaces of the chair itself. In an alternative embodiment an aluminum skin can be placed on the entire exterior of the chair which makes it light weight yet sturdy and reduces the risk of rust or deterioration. Additionally, other materials such as leather or rubber, metal or wood may be used depending on the desired use or location of the convertible chair.
In the embodiment shown in
In some aspects, a retraction and deployment mechanism may be provided, which may include components that stabilize, synchronize, assist the lifting/deployment of, or slow/dampen the retraction of, the chair cover in and out of a chair pocket. Suitable components can include, for example, any suitable rails, racks, pinions, guides, tracks, synchronizing axles, rotary dampers, loaded dampers, no friction guides, low friction stabilizers, torsion spring counterbalances, and concealed hinges. For example, a loaded rotary damper may be provided and, for example, directly built into the pinion, which can allow controlled deceleration of the chair cover into the pocket.
As another example, a torsion spring counterbalance assembly can be provided, which can do the heavy lifting of the chair cover, making it seem much lighter than it actually is (e.g., less than 1/10th of the actual weight of the chair cover). Such mechanisms are often provided with garage doors, making it so that just about anyone can open the door, and can be useful for the convertible chairs described herein, which can include any suitable number of seats and chair covers (e.g., 1, 2, 3, 4, 5 of each of a seat, a top portion, and a front portion; 1, 2, 3, 4, 5 or more seats with a single large top portion and front portion to cover all of the seats; 1, 2, 3, 4, 5 or more seats with fewer chair covers than seats—e.g., a chair cover covering more than one seat when in a closed box configuration). A torsion spring counterbalance assembly can comprise two torsion springs that are wrapped around the pinion axle to assist in the deployment and retraction of the chair cover by balancing much of the cover weight when traveling vertically into and out of the pocket. The torsion loaded into the spring can safely slow the vertical retraction in a downward direction. It can also assist in the lifting of the cover up and out of the pocket. The spring can be held to the pinion axle by a shaft collar on one end to allow the spring to rotate and store the energy into the coil while another end of the spring can be held stationary. When the pinion rolls or rotates along the rack vertically, the torsional energy stored in the spring coil can be increased (e.g., down) or decreased (e.g., up) by the rotations.
While an exemplary retraction and deployment mechanism comprising a rack and pinion system and torsion spring counterbalance assembly is described herein, it should be appreciated that any and all other suitable retraction and deployment mechanisms are contemplated herein.
Thus, specific examples of convertible chairs have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein.
