[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 600,917, filed November 20, 2023, which is incorporated herein by reference in its entirety. Technical Field

[0002] The present invention relates generally to a rocking chair, and more specifically, to an improvement of a rocking chair that can be folded and unfolded between a usable unfolded state and a basic folded state for transport and storage. Background Technology

[0003] This section is intended to provide background or context. This specification may include implementable technical concepts, but not necessarily previously proposed or implemented solutions. Unless otherwise stated, the descriptions in this section are not considered prior art in the specification and claims, nor are they acknowledged as prior art by their inclusion in this section.

[0004] Various chairs have been modified to be foldable for transport and / or storage. These chairs typically have a frame made of long structural members (preferably metal). The frame of such chairs has laterally spaced left and right frame side assemblies, which are generally parallel to each other. In the unfolded state, each frame side assembly has: a front leg member extending generally vertically upwards; and a rear leg member whose upper end is pivotally connected directly or indirectly to the upper end of the front leg member and extends obliquely downwards and backwards from the upper end of the front leg member. These frame side assemblies also include an upwardly extending backrest support member whose lower end is pivotally connected via a central linkage mechanism to a position between the two ends of the rear leg member. This linkage mechanism positions the backrest support member such that when the chair is unfolded from a closed or flat-folded storage state to a usable open or unfolded state, the lower end of the backrest support member is supported by the rear leg member and is obliquely positioned upwards and backwards from the rear leg member. These frame side components also include seat support members, which are generally supported by the front and rear leg members and configured approximately horizontally when the chair is in the unfolded position.

[0005] Because of the complex interconnections between all frame components, both front-to-back and side-to-side, these chairs typically require all legs to remain in contact with the ground at all times to ensure the chair's safety and structural integrity during use. However, there is a desire for an equally foldable and portable rocking chair that allows users to rock or lean back as needed during picnics or outdoor activities.

[0006] Many foldable portable chairs cannot rock due to their design and construction. Adding a component that allows the user to sit and rock often affects the chair's ability to fold and store, or makes it difficult to maintain sufficient portability. Furthermore, existing foldable rocking chair designs are generally unsuitable for most outdoor scenarios, especially on soft ground or sand. The main limitation of these chairs lies in their use of arched tracks to support the frame. With arched tracks, each side of the chair maintains only one point of contact with the ground. On sand or soft ground, this increases the risk of one or both sides of the chair sinking or getting stuck, affecting the rocking function, and more seriously, compromising the integrity and safety of the seated person.

[0007] Another limitation of many rocking chairs is that they can only be used as rocking chairs and cannot be stabilized into ordinary chairs that do not rock.

[0008] Other chair designs that can be folded into a stowed or bundled state to take up less storage space have been developed. For example, some chair designs can fold in multiple directions, at least reducing the front-to-back and lateral dimensions between the unfolded assembled state and the folded stowed state. However, these chair designs are generally not suitable for certain outdoor uses, such as beach or picnics. Due to the complexity of the connection methods of the various frame components that make up the chair frame, and the need to ensure that all the legs of these chairs are grounded during use for safety and integrity, many chairs that can fold in multiple directions cannot have a rocking function. Further reference is made to "Collapsible and Portable Rocking Chair", U.S. Patent No. 9,060,611, issued on June 23, 2015, which is incorporated herein by reference in its entirety.

[0009] Some folding chairs use a double-V design as their support frame. This design allows the chair to take up less space when folded compared to traditional folding chairs.

[0010] In view of the above, there is a need for a foldable rocking chair (which may adopt a double V-shaped design) that allows the user to rock in its unfolded state, and is foldable to reduce the space occupied by the chair in the folded state. Furthermore, there is a need for a chair that can be folded with minimal force without restricting or weakening the structural characteristics that enable the rocking function. Further, there is a need for a rocking chair that allows the user to rock as needed while seated, without compromising the chair's folding and transportability, or affecting its safety and structural integrity, especially on soft surfaces and sandy surfaces. Therefore, the overall objective of this invention is to provide a foldable portable rocking chair design that overcomes the problems and defects of folding chairs and rocking chairs, thereby significantly improving the chair's practicality in its unfolded state, and facilitating transport and / or storage in its folded state.

[0011] Overall, there is a need for a foldable rocking chair that users can easily fold with minimal effort and that can be used as a rocking chair or a regular chair when unfolded.

[0012] This invention addresses these problems and provides a means of avoiding the drawbacks associated with these existing folding chair designs. Summary of the Invention

[0050] Figure 1This describes at least one embodiment of the rocking chair 10 according to the present disclosure. The rocking chair 10 advantageously allows the chair 10 to rock and can also be folded up and substantially stowed for transport and / or storage. Furthermore, due to the design of the frame and crossbeams, the rocking chair 10 remains stable and secure during rocking, as will be described in detail below. The frame and crossbeam design also allows the rocking chair to be folded into a slimmer profile compared to some conventional folding chairs. Therefore, the rocking chair 10 provides a portable, safe, and stable rocking chair 10 that can be moved to different locations for use.

[0051] In the illustrated embodiment, the rocking chair 10 is shown in an unfolded state (also referred to as an open state) and is ready for use. The rocking chair 10 includes a frame 12 that supports a seat support plate 14 and a backrest support plate 16. As shown, the seat support plate 14 and backrest support plate 16 are generally rectangular. In other embodiments, the seat support plate 14 and backrest support plate 16 can be of any shape or size. Figure 1 As shown, the seat 14 and backrest 16 typically comprise flexible panels connected by flexible connecting plates 18; however, in other embodiments, the seat 14 and backrest 16 may also be separate components. When the rocking chair 10 is in the unfolded state to accommodate and support the seated person, the panels 14 and 16 are typically in a taut state.

[0052] In at least one embodiment, the seat 14 and backrest 16 may be made of fabric or other suitable flexible, durable, and weather-resistant sheet material. The panels 14 and 16 may be flexible to adapt to the occupant, thereby improving chair comfort. In the unfolded state, the seat 14 and backrest 16 extend between the side components 20 and generally remain taut to support the occupant. When the chair is folded down, the panels 14 and 16 become relaxed and fold along with the chair in the folded state. Therefore, this design can be used for chairs of different heights, such as chairs (with shorter legs) or stools (with longer legs), without affecting the operation and use of the chair according to the invention.

[0053] In some embodiments, the seat 14 and backrest 16 may be made of nylon mesh, padded fabric, and / or canvas. In other embodiments, the seat 14 and backrest 16 may be made of hinged plastic sheets. In alternative designs, the seat 14 and backrest 16 may be rigid structures that fold together with the chair frame 12. For example, the seat 14 and backrest 16 may be formed of plastic sheets that are hinged in the middle when the rocking chair 10 is folded, and snap into a single panel when the rocking chair 10 is unfolded.

[0054] Typically, the frame 12 consists of multiple rigidly connected and / or pivotally connected frame members to define the frame 12 and allow it to be folded and stowed into a form convenient for transport and storage. The frame members may be made of durable, lightweight materials such as tubular metal, metal alloys, or high-strength plastics. Various elongated structural components or members constituting the chair frame 12 may be made of tubular materials with non-circular cross-sections, such as extruded metal tubes with square, oval, or elliptical cross-sections, or extruded metal tubes with circular cross-sections may also be used.

[0055] Reference Figures 1 to 6 The frame 12 has a pair of side components 20, which are composed of structurally identical but mirror-symmetrical frame members. In other embodiments, the rocking chair does not require mirrored elements. In other words, the frame 12 may have an asymmetrical structure; for example, the lengths of the crossbeams on opposite sides may be unequal, allowing elements to fold in specific positions, and / or the chair may have a cup holder or tray on one side. Therefore, various modifications to the frame design are possible without departing from the spirit and principles of this disclosure.

[0056] Returning to the side components 20, the left and right frame side components are labeled 20L and 20R respectively. They are configured to be laterally or horizontally spaced and generally parallel when the rocking chair 10 is in the unfolded state. In the illustrated embodiment, the left frame side component 20L and the right frame side component 20R are interconnected and can be laterally folded (i.e., folded in opposite directions), allowing the rocking chair 10 to enter a position approximately as shown in the diagram. Figure 8 The folded state is shown. The concepts presented in this paper are easily applicable to frame designs employing different folding methods, including but not limited to the front-to-back folding method associated with standard folding chairs.

[0057] like Figure 2 As shown, the frame side assembly 20 includes a generally closed frame ring 25, which is bent from an axially extending tubular material to form an armrest portion 22, a front leg portion 24, a lower support portion 26, and a rear leg portion 28. The frame side assembly 20 may have more or fewer portions. For example, the frame side assembly 20 may not include the lower support portion 26. In another example, the frame side assembly 20 may include a front crossbeam extending between a pair of frame side assemblies 20.

[0058] refer to Figures 6 to 7 The backrest support member 30 is connected to the frame 12 at the backrest support joint 31. The backrest support member 30 can be placed in an upright position, in which case the backrest support member 30 is relatively perpendicular to the armrest 22; or, the backrest support member 30 can be placed in a folded position (e.g., ...). Figures 7 to 8As shown (also known as the closed state), the backrest support member 30 is relatively parallel to the armrest portion 22. In an alternative embodiment, the backrest support member 30 is detachably connected to each frame side assembly 20 to facilitate the unfolding and folding of the rocking chair 10. Removing the backrest support member 30 during folding further reduces the storage and transport size of the folding rocking chair 10.

[0059] Furthermore, each part of the illustrated frame ring 25 can be an independent component, and the frame components are interconnected by rigid or flexible joints to collectively form the frame side assembly 20. Even further, the frame side assembly 20 can be composed of an open design rather than a closed frame ring 25, including the unfolded form of the front and rear legs, which is generally associated with a standard folding chair design. The frame components are interconnected by rigid, pivoting, sliding, and / or telescopic joints, thereby enabling easy folding and unfolding of the chair between its unfolded and folded states.

[0060] The frame members of the side assemblies 20L and 20R can be arranged in a generally parallel extending vertical plane. (Refer to...) Figure 1 and Figure 3-4 The frame side assembly 20 is interconnected via one or more first crossbeam members 56 and one or more second crossbeam members 57. The first crossbeam member 56 is pivotally connected to the lower portion of the front leg 24 of the associated frame side assembly 20 and has a first frame hinge 65 for closing the first crossbeam member 56. The second crossbeam member 57 is pivotally connected to the first crossbeam member 56 at a pivot point 63 and has a second frame hinge 67 for closing the second crossbeam member 57.

[0061] The middle front and rear extensions 60 of the second crossbeam 57 (marked at...) Figure 6 The middle (front) extension 60 extends between the front 58 and the rear 62, and this middle front-rear extension 60 serves as the seat support member of the rocking chair 10. Figure 1 As shown, in the unfolded state of the rocking chair 10, the seat plate 14 extends between these seat supports of the second crossbeam member 57 to serve as the seat of the rocking chair 10.

[0062] like Figure 6 As shown, the rear portion 61 of the first crossbeam member 56 connects between the lower portions of each rear leg portion 28 of the chair frame 12, forming a generally pivotable, downward-facing V-shaped rear frame, which is connected at a first pivot point 65. In other embodiments, the first crossbeam members 56 pivot relative to each other at the first pivot point 65, forming an angle between them. In such embodiments, this angle can be between 20 degrees and 180 degrees. In other embodiments, this angle can be less than 20 degrees or greater than 180 degrees. In still other embodiments, the first crossbeam members can be formed in any shape, such as a W shape, a straight line, an M shape, etc.

[0063] The second crossbeam member 57 connects between the upper portions of the rear legs 28 of the chair frame 12 and forms a generally pivotable, upward-facing V-shaped rear frame, which connects at the second pivot point 67. In other embodiments, similar to the first crossbeam member 56 described above, the second crossbeam members 57 pivot relative to each other at the second pivot point 67, forming an angle between them. In such embodiments, this angle can be between 20 degrees and 180 degrees. In other embodiments, this angle can be less than 20 degrees or greater than 180 degrees. In still other embodiments, the second crossbeam member 57 can be formed in any shape, such as a W-shape, a straight line, an M-shape, etc.

[0064] In embodiments where the first crossbeam member 56 and the second crossbeam member 57 are V-shaped, such as Figure 1 as well as Figures 3 to 4 As shown, when the rocking chair 10 is opened to the unfolded or open state, the first crossbeam member 56 and the second crossbeam member 57 together form a double "V-shaped frame". Figure 8 As shown, when the rocking chair 10 is folded up, the double "V-shaped frame" closes. Similarly, the front portions 58 of the first crossbeam member 56 and the second crossbeam member 57 are connected between the front legs 24 of the chair frame 12, and similarly form a pivotable front double V-shaped frame connected at the central pivot point 66. When the rocking chair 10 is opened to the unfolded or open state, the front portion 56 also opens into a "V" shape; and when the rocking chair 10 is folded to the closed position, the front portion 56 also closes.

[0065] In the embodiment employing a double "V-shaped frame," frame side assemblies 20L and 20R are interconnected, partially achieving lateral (i.e., left-right) folding of the frame 12 via a movable double V-shaped frame connector assembly formed by the pivotal interconnection of the first crossbeam member 56 and the second crossbeam member 57. That is, when the rocking chair 10 is being folded, the first crossbeam member 56 and the second crossbeam member 57 are pivoted to close the double V-shaped frame, thereby flattening the first crossbeam member 56 and the second crossbeam member 57 and bringing them closer together. As the first crossbeam member 56 and the second crossbeam member 57 are flattened, the frame side assemblies 20L and 20R also move inward and close together.

[0066] Alternatively or additionally, in embodiments where the second crossbeam member forms a low "V" shape, the low "V" shape formed by the second crossbeam member 57 may include an orientation toward the chair 10 such as... Figure 2 The centerline CL 11 shown is offset by an offset portion 13. The offset portion 13, for example, provides space for the user's ankles, preventing them from being squeezed or contacted during forward-leaning movements. In contrast, a conventional director's chair is placed statically on the ground, and therefore such activities are not considered.

[0067] In the open and unfolded state, the first crossbeam member 56 and the second crossbeam member 57 also provide support for the frame 12 by balancing and redistributing the forces exerted on the frame 12 by a person sitting on the seat plate 14 and leaning back on the backrest plate 16. Figure 1 and Figures 3 to 4 As shown, the second crossbeam member 57 can be further secured to the frame 12 via a support bracket 68 pivotally connected between the second crossbeam member 57 and the frame ring 25. Furthermore, referring to… Figure 3 and Figure 6 The first crossbeam member 56 is pivotally connected to the front leg 24 of one of the frame side assemblies (e.g., 20L), while the other end of the first crossbeam member 56 is pivotally connected to the front leg 24 of the opposite frame side assembly (e.g., 20R), typically connecting to the lower portion of the leg 24 and the leg 28. Similarly, the rear end 62 of the remaining first crossbeam members 56 is pivotally connected to the rear leg 26 of the frame side assembly 20.

[0068] The front part 58 and the rear part 62 of the second crossbeam member 57 are connected by means of... Figure 9 The support brackets 68 shown are respectively connected to the front and rear legs of the frame side assembly 20. More specifically, each support bracket 68 has a first pivot opening 71 connected to the second crossbeam member 57 and a second pivot hole 72 connected to the frame side assembly 20. When the second crossbeam member 57 rotates about the pivot point 67 connecting them, the second crossbeam member 57 pulls the frame side assemblies 20L and 20R together via the support brackets 68. When the rocking chair 10 is in its unfolded state, the second crossbeam member 57 is in an open V-shaped frame state and is supported on the support reinforcement 73 of the support bracket 68, which, while distributing the weight of the seated person via the frame 12, limits further opening of the second crossbeam member 57.

[0069] In another alternative embodiment, the chair may include a single V-shaped member, similar to the crossbeam member 57. A horizontal crossbeam may be connected to both this single V-shaped member and the side assembly 20. The horizontal crossbeam may also include, for example, a pivot / hinge located at the center of the horizontal crossbeam to facilitate chair folding.

[0070] refer to Figure 1 and Figure 5 The rocker mechanism 32 is connected to the rear side of the frame ring 25. As shown, the rocker mechanism 32 extends outward and downward at an angle from the rear side of the frame ring 25. The rocker mechanism 32 extends to the support rail 34 approximately at the point where the armrest 22 connects to the rear leg 28. The support rail 34 supports and facilitates the rocking motion of the rocking chair 10 when the seated user wants to rock. Figure 1In the illustrated embodiment, the support rail 34 also supports the lower support portion 26 of the frame ring 25 and is generally positioned below the rear leg portion 28 of the frame ring 25. The rocker mechanism 32 is preferably connected to a static rail design, as shown, which exhibits a significant improvement over prior art rocking chair designs using arched rails. For example, the static rail design provides better stability on soft or sandy surfaces, which is unsuitable for prior art rocking chair designs.

[0071] Reference Figure 5 The rocker mechanism 32 includes an axially extending tubular member 38, which is pivotally connected at a first end 47 to the rear leg 28 of the frame side assembly 20 via a pivot joint 40 and a pivot pin 42. A second end 45 of the tubular member 38 is received within a sleeve 44. More specifically, the second end 45 is connected to a spring 46, which is also received within the sleeve 44, with its lower end fixed within the sleeve 44. The lower end of the sleeve 44 is pivotally connected to a support rail 34 via a universal joint 48 and pivot pins 50 and 52 to move with the rocker chair 10. The universal joint 48 allows for a degree of flexibility to accommodate occupants of different sizes and weights without impairing the user's ability to recline and rock in the chair. In an alternative design, the lower end of the sleeve 44 may only have a third foot 36c for direct contact with the support surface without the support rail 34. In another alternative design, the tubular member 38 and sleeve 44 of the rocker mechanism 32 can be designed to move with the rocking motion of the rocking chair 10, such that the lower end of the sleeve 44 (third foot 36c) is off the ground when the rocking chair 10 tilts forward and grounded when the rocking chair 10 rocks backward to support the rocking chair 10 in the backward position.

[0072] Refer again Figure 5 The chair frame 12 is mounted on or includes a load-bearing feature (e.g., fulcrum 54) to facilitate the back-and-forth rocking motion of the chair 10. Figure 5As shown, fulcrum 54 is located at the front end of the support rail 34 and pivotally connected to the lower support portion 26 of the frame ring 25 to allow the frame ring 25 to pivot relative to the support rail 34. This pivoting allows the rocking chair 10 to rock. Generally, when the occupant shifts their weight backward, for example by leaning back against the backrest 16, the frame ring 25 pivots rearward at fulcrum 54. As the frame ring 25 pivots rearward, the tubular member 38 of the rocker mechanism 32 moves with the frame ring 25, moving generally rearward and downward toward the rear end of the support rail 34. As the tubular member 38 moves, it slides downward within the sleeve 44 and applies pressure to the spring 46, thereby cushioning the tubular member 38 and preventing the rocking chair 10 from tipping over. The spring 46 further applies a reaction force to the tubular member 38 in the opposite direction, pushing it upward out of the sleeve 44 and moving upward and forward relative to the rear end of the support rail 34. This movement of the tubular member 38 (typically combined with a corresponding shift in the weight of the seated person) causes the frame ring 25 to pivot forward about the fulcrum 54. During this pivoting movement, the rocker mechanism 32 in the illustrated embodiment pivots relative to both the frame ring 25 and the support rail 34, thereby maintaining contact with both. Therefore, the rocker mechanism 32 does not leave the ground during rocking, improving the safety of the rocking chair 10 by eliminating components that could pinch or crush a person (e.g., feet caught between the rocking chair 10 and the ground or support surface). In an alternative design, the lower end of the rocker mechanism 32 may move with the frame ring 25 and contact the ground or support surface during rocking chair 10 movement.

[0073] In alternative chair designs, such as those that do not use the closed frame ring 25 shown in the figure, the load-bearing feature (e.g., fulcrum 54) can be connected to the rear leg member or at least one horizontal extension thereof, and can still cooperate with the rocker mechanism 32 as described above to assist the rocking motion of the chair.

[0074] Reference Figure 1 and Figure 2 The rocking chair 10 also has three feet 36 on each frame side assembly 20, serving as contact points between the rocking chair 10 and the ground or support surface on which it is placed. In other embodiments, each frame side assembly 20 of the rocking chair 10 may have one, two, or more feet. In a preferred use of the rocking chair 10, regardless of the embodiment, at least two of these feet 36 or contact points on each frame side assembly 20 always remain in contact with the ground or support surface on which the rocking chair 10 is placed. In this way, the rocking chair 10 differs from conventional rocking chair designs, which typically use slides or tracks and maintain only one contact point with the support surface when rocking. By maintaining multiple contact points, the stability and safety of the rocking chair 10 are improved.

[0075] like Figure 2As shown, the first foot 36a is located at the front of the frame side assembly 20, approximately below the front leg 24 of the frame ring 25. The second foot 36b and the third foot 36c are respectively located at the ends of the support rail 34, with the third foot 36c approximately below the lower end of the rocker mechanism 32, serving to bear the main weight of the user and the rocker chair 10 when it rocks backward. When using the rocker chair 10, when it is in a forward-leaning position and not rocking significantly, the first foot 36a and the second foot 36b are sufficient to support the rocker chair 10. As shown, the third foot 36c also remains in contact with the ground, but does not need to support the rocker chair 10 in the forward-leaning position. When the rocker chair 10 rocks backward, the first foot 36a lifts off the ground, and the second foot 36b and the third foot 36c support the rocker chair 10. As previously stated, regardless of the position of the rocker chair 10, the third foot 36c remains approximately in contact with the support surface. However, in an alternative design, the third foot 36c can be designed to lift off the ground when the rocking chair 10 is in a forward-leaning position.

[0076] In use, in its unfolded state, the frame 12 is typically supported on a generally horizontal support surface, such as a floor or ground. As previously described, the chair 10 is stabilized on the support surface by the first leg 36a, the second leg 36b, and the third leg 36c. When the rocking chair 10 is in the forward-leaning position, even when the user is leaning against the backrest 16, the rocking chair 10 functions as a normal and completely stable chair, supported at least by the first leg 36a and the second leg 36b. If the user wants to rock the rocking chair 10, they can, for example, lean back and push the backrest 16, shifting their weight backward, thereby causing the frame ring 25 of the frame side assembly 20 to pivot relative to the fulcrum 54 of each support rail 34. When the rocking chair 10 pivots backward, the first leg 36a lifts off the ground, but the rocking chair 10 remains in contact with the support surface by the second leg 36b and the third leg 36c, thus maintaining stability. When the rocking chair 10 pivots forward, the first leg 36a moves to contact the support surface.

[0077] In its unfolded state, the flexible seat 14 forms a generally taut seat support and the flexible backrest 16 forms a generally taut backrest support, thereby accommodating a user in an upright sitting position. The seat 14 and backrest 16 are fixed to specific locations on the frame 12, which together form and provide seat and backrest support for the user. As shown, the backrest support member 30 is preferably mounted on the rear leg portion 28 and can be positioned to extend upward from there. In an alternative embodiment of the chair, the backrest support member 30 can be folded down to a position adjacent to the armrest portion 22; or in another alternative embodiment, when the chair is stowed, the backrest support member 30 is folded down to a position adjacent to the rear leg portion 28. Furthermore, the backrest 16 can be detached from the frame 12, either from the backrest support member 30 or together with the backrest support member 30, to allow for some degree of relaxation in the backrest 16. This helps improve the ease and safety of unfolding and folding the chair, because the frame side assembly 20 is subjected to great stress when the first crossbeam member 56 and the second crossbeam member 57 are moved to the unfolded state of the rocking chair 10.

[0078] More specifically, when the first crossbeam member 56 and the second crossbeam member 57 are in a partially open state ( Figure 7 ), from a relaxed state or a closed form, that is, set to a state where they are adjacent to each other ( Figure 8 Finally, it enters the unfolded state, at which point the two roughly form a double V shape. Figure 1 When the first crossbeam member 56 and the second crossbeam member 57 are curved in opposite directions, the upper end of each frame side assembly bends outward, essentially forming a trapezoidal layout in the chair frame 12. This action causes the upper end of the frame side assembly 20 (particularly the backrest support member 30) to be pushed outward. At the location where the backrest panel 16 connects to the backrest support member 30, the panel material is stressed and provides resistance to the bending movement of the chair frame 12.

[0079] When the rocking chair 10 is folded up for transport and / or storage, the user simply presses inward on each side of the frame 12, causing the first crossbeam member 56 and the second crossbeam member 57 to pivot relative to each other about their pivot point 63, from a double V-shape associated with the unfolded state of the rocking chair 10, to a position as if... Figure 8The first crossbeam member 56 and the second crossbeam member 57 are arranged substantially parallel to each other. When the first crossbeam member 56 and the second crossbeam member 57 pivot about pivot point 63 and the first frame hinge 65 and the second frame hinge 67 relative to each other, the frame side assemblies 20L and 20R move synchronously in their parallel planes, thereby forming the rocking chair 10 in a flat, folded state. To unfold the rocking chair 10, the user simply pulls the frame side assemblies 20L and 20R outwards until the first crossbeam member 56 and the second crossbeam member 57 pivot to the desired double V-shape. Alternatively, the user can separate the first crossbeam member 56 and the second crossbeam member 57 and push them outwards until the chair frame 12 engages in the unfolded state.

[0080] like Figure 8 As shown, the crossbeam members 56 and 57 are nested within each other; for example, in the closed or folded state, the first crossbeam member 56 covers the second crossbeam member 57. This gives the chair a "slim folded" appearance. This nesting can be formed by the "Z"-shaped profile of the first crossbeam member 56, which also provides additional rigidity to support rocking movements.

[0081] Alternative designs for the rocking chair may include other frame side components, and different legs may be used without departing from the focus of the invention. For example, such as Figure 1 As shown in the embodiments, frame side assemblies 20L and 20R are composed of closed frame rings 25, which are mounted on fulcrum 54 of the support rail 34. The foldable portable rocking chair according to this disclosure can also employ an open frame structure, wherein the frame side assemblies are composed of interconnected frame members to form independent front and rear legs. In this alternative design, the frame remains connected to a pivot point that facilitates the chair's back-and-forth rocking; for example, the rear legs or their extensions may be mounted to the pivot point. As described above, in this alternative design, regardless of the structure, each frame side assembly maintains at least two contact points with the support surface to ensure adequate safety and structural integrity of the chair during use.

[0082] Furthermore, the rocker mechanism 32 can take various forms without departing from the spirit and principles of the invention. For example... Figure 5As shown, the rocker mechanism 32 includes a compression spring 46 disposed within a sleeve 44, which houses tubular members 38 extending from the rear of each frame side assembly 20. In an alternative design, the rocker mechanism 32 can be replaced by torsion springs disposed at the lower part of each frame side assembly, for example, torsion springs disposed at the fulcrum of each frame assembly supporting the slide rail. Furthermore, the rear rocker mechanism design can be replaced by a front rocker mechanism design, i.e., using compression springs in the design of the chair's front legs. Further, a combination of springs can be used, for example, compression springs on both front legs of the chair and on the rearward-extending members, to prevent the chair from tipping over when rocking backward.

[0083] The rocking chair 10 may also have one or more accessories. For example, return. Figure 1 The seat 14 has a handle 80 on one side of the frame 12. Typically, the handle 80 is aligned with the central front-rear section 60 of the second crossbeam member 57, which defines the width of the chair. The handle 80 can also be used as a carrying handle for the rocking chair 10 when fully folded. In other embodiments, the handle 80 can be located anywhere on the rocking chair 10, such as the top of the backrest 16, the sides of the frame 12, etc. To fold the rocking chair 10, when the rocking chair 10 is in the unfolded state, the user pulls upward on the handle 80 mounted on the seat while simultaneously gripping the armrest portion 22 of the frame side assembly 20 adjacent to the handle 80. When sufficient tension and rigidity of the seat 14 are required or demanded to ensure the comfortable use of the rocking chair 10, folding the rocking chair 10 using conventional methods (i.e., folding and folding the chair frame 12 by pressing the chair frame members) can become difficult. Using the handle 80 makes the folding process much easier.

[0084] Alternatively, a transport handle may be provided. When the rocking chair 10 is folded up, this handle can be used to move the folded rocking chair 10 from one place to another.

[0085] As described above, the rocking chair allows users to both rock and fold up for transport and / or storage. As previously mentioned, thanks to the design of the frame and crossbeams, the rocking chair remains stable during use and ensures safety while rocking. Therefore, the rocking chair provides a portable, safe, and stable option that can be moved to different locations.

[0086] The foregoing description of embodiments of the present invention has been presented for illustrative and explanatory purposes. It is not intended to be exhaustive or to limit the invention to the forms disclosed. Obvious modifications and variations are possible based on the foregoing disclosure. The described embodiments have been selected to optimally illustrate the principles of the invention and its practical application, thereby enabling those skilled in the art to use the invention in various embodiments and with various modifications according to the intended particular use.
