Description

Technical Field

[0001] This utility model relates to the technical field of seating, and more specifically to a folding chair that can rotate and rock. Background Technology

[0002] Folding chairs typically fold and store using a hinge mechanism. Their biggest advantage is their ability to be quickly unfolded for use and folded away to save space. Folding chairs usually consist of a folding frame supporting a fabric surface, which can be unfolded using the frame and secured by the fabric. Folding chairs are simple and practical in structure, lightweight, and easy to carry, making them suitable for various occasions requiring temporary seating, such as outdoor camping, picnics, and fishing. After folding, they can usually be stacked or hung for storage, greatly optimizing storage and transportation efficiency while balancing practicality and space efficiency.

[0003] Chinese patent CN217137286U discloses a folding chair. When the seat fabric is taut, the rocking mechanism will not tip forward or backward, allowing the user to maintain balance. To fold the chair back, the support arm is shortened, loosening the seat fabric. The support arm can then be flipped towards the second support frame to fold the entire chair. A bearing component is provided between the upper and lower blocks, allowing the upper block to rotate relative to the lower block.

[0004] US Patent 9282824B2 discloses a foldable portable rocking chair including left and right frame side assemblies defining front and rear leg members, armrests, seat support members, and back support members. A rocker mechanism is attached to the chair frame to support the chair during rocking motion and to help the chair rock with the user's shifting weight. However, when users want to relax and have fun, they are limited to sitting in one position, which is monotonous and fails to achieve the purpose of entertainment and leisure.

[0005] It is evident that the existing folding chairs have relatively simple functions, generally only having two states: unfolded and folded. They can only meet the needs of sitting and relaxing, and cannot be as multifunctional as regular chairs. Even if they are multifunctional, they are relatively simple, either rotating or rocking.

It should be understood that these drawings are not only for explaining and illustrating the present invention, but also, where necessary, for defining the present invention. Detailed Implementation

[0030] The implementation and use of specific embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of particular ways of implementing and using this utility model, and are not intended to limit the scope of this utility model.

[0031] The directional and positional terms used in this utility model can be referred to as follows: Figures 1 to 9 The exemplary structure shown is explained. Sequential terms such as "first," "second," etc., are used to describe various elements without intending to limit the positional, temporal, or importance relationships between these elements; such terms are merely used to distinguish one element from another.

[0032] The preferred embodiments of this utility model will now be described with reference to the accompanying drawings. Figure 1 and Figure 2 The overall structure and disassembled structure of the folding chair 10 provided by this utility model are schematically shown respectively. The folding chair 10 includes a rotating rocking structure and a seat frame, and the rotating rocking structure and the seat frame are connected by a hinge. Figure 3 A cross-sectional view of the rotating rocking structure of the folding chair 10 is shown, as follows. Figures 1 to 3 As shown, the rotating and rocking structure includes a base 100, a rocking member 200, and a rotating member 300. The rocking member 200 can rock relative to the base 100, and the rotating member 300 can rotate relative to the base 100, so that the folding chair 10 has both rotating and rocking functions.

[0033] Specifically, the base 100 has a central axis AX. The rotating component 300 is rotatably connected to the base 100 around the central axis AX, and the rocking component 200 is rotatably connected to the base 100 around a rotation axis AY. The rotation axis AY passes through the central axis AX and is perpendicular to it. By setting up this rotating and rocking structure, the user can rotate around the central axis AX and rock around the rotation axis AY when sitting on the folding chair 10, thus achieving functional versatility, improving comfort, and meeting more user needs. Furthermore, the rotation axis AY passes through the central axis AX and is perpendicular to it, meaning that the rotation axis AY is perpendicular to and coplanar with the central axis AX. This allows the rotation and rocking functions of the folding chair 10 to be achieved using only two structural components. Therefore, the rotating and rocking structure in this embodiment is relatively simple and easy to manufacture. To make the layout of the rotating and rocking structure more reasonable, the rotating component 300 and the rocking component 200 are respectively arranged on both sides of the base 100 along the central axis AX.

[0034] Figure 4 and Figure 5 The diagram shows the structure of the base 100 at different angles. Figure 6 and Figure 7 The diagram shows the structure of the rocking member 200 at different angles, combined with... Figures 3-7 As shown, the base 100 and the rocker 200 limit the rotation angle of the rocker 200 relative to the base 100 through mutually cooperating limiting structures 210. Specifically, the limiting structure 210 includes a first limiting structure 140 disposed on the base 100 and a second limiting structure 211 disposed on the rocker 200. The rotation angle of the rocker 200 relative to the base 100 is limited by the abutting cooperation between the first limiting structure 140 and the second limiting structure 211. Furthermore, a set of limiting structures 210 can be provided on both sides of the plane formed by the rotation axis AY and the central axis AX. The two sets of limiting structures 210 correspond to the front and rear sides of the user sitting on the folding chair 10, and the rocking angles limited by the two sets of limiting structures 210 can be the same or different to achieve a rocking angle that better suits the user's preferences.

[0035] Continue to refer to Figure 2 and Figure 3 The rotating rocking structure also includes a first shaft assembly 230 extending along the rotation axis AY. The base 100 and the rocking member 200 are rotatably connected through the first shaft assembly 230. The first shaft assembly 230 may include a shaft body, a retaining ring, a shaft shoulder, or a round nut, etc.

[0036] Furthermore, the rotating rocking structure also includes a pair of elastic elements 220. Each elastic element 220 has two ends abutting against the base 100 and the rocking element 200, respectively, to provide cushioning when the base 100 and the rocking element 200 rotate relative to each other, allowing the user to experience a more stable and comfortable rocking experience due to the cushioning force. To prevent the elastic elements 200 from deviating from their predetermined positions during long-term rocking use, the rocking element 200 is provided with a first positioning ring 240, and the base 100 is provided with a second positioning ring 130 opposite to the first positioning ring 240. The first positioning ring 240 and the second positioning ring 130 can be appropriately protruded from their corresponding planes. One end of each elastic element 220 is fitted onto the first positioning ring 240, and the other end is fitted onto the second positioning ring 130, thereby limiting the position of each elastic element 220 between the rocking element 200 and the base 100. The elastic element 220 may include at least one of springs and rubber parts. Different types of elastic elements 220 can be selected as needed to meet different usage requirements. Figure 3 The elastic element 220 shown is a spring, with one end of the spring sleeved on the first positioning ring 240 and the other end sleeved on the second positioning ring 130 to limit the spring.

[0037] Figure 8 and Figure 9 The diagram shows the structure of the rotating component 300 at different angles, and is combined with... Figures 2-5 As shown, the base 100 and the rotating member 300 are rotatably connected about the central axis AX via a second shaft assembly 340. The second shaft assembly 340 may include a shaft body, a retaining ring, a shaft shoulder, or a round nut, etc.

[0038] In some embodiments, to reduce the friction between the base 100 and the rotating member 300, the rotating rocking structure further includes a bushing structure. Specifically, the base 100 is provided with a base hole 110, and the rotating member 300 is provided with a rotating hole 350. The base hole 110 is open to the rotating member 300, and the rotating hole 350 is open to the base 100. The base hole 110 and the rotating hole 350 are aligned along the central axis AX, and at least one of the base hole 110 and the rotating hole 350 is fitted with a bushing structure. A second shaft assembly 340 passes through the base hole 110, the rotating hole 350, and the bushing structure to connect the base 100 and the rotating member 300.

[0039] Furthermore, the bushing structure is preferably disposed on the base 100 and the rotating member 300 respectively, and includes a first bushing 310 and a second bushing 320. The first bushing 310 is partially embedded in the base hole 110, and the second bushing 320 is partially embedded in the rotating hole 350. The base 100 is provided with at least one first boss 120 protruding towards the rotating member 300, and the first bushing 310 is correspondingly provided with at least one first through hole 312 through which the first boss 120 passes. The rotating member 300 is provided with at least one second boss 330 protruding towards the base 100, and the second bushing 320 is correspondingly provided with at least one second through hole (not shown) through which the second boss 330 passes. Figure 4 and Figure 8 As shown, for example, four first bosses 120 can be provided on the base 100. The four first bosses 120 can be evenly arranged around the central axis AX. The first bushing 310 is limited to the base 100 in a plane perpendicular to the central axis AX by the docking of these first bosses 120 with the corresponding four first through holes 312. Furthermore, four second bosses 330 can be provided on the rotating member 300. The four second bosses 330 can be evenly arranged around the central axis AX. The second bushing 320 is limited to the rotating member 300 in a plane perpendicular to the central axis AX by the docking of these second bosses 330 with the corresponding four second through holes.

[0040] Continue to refer to Figure 1 and Figure 2 As shown, the folding chair 10 also includes a chair fabric 600. The seat frame includes a first support frame 400 and a second support frame 500. The first support frame 400 is hinged to a rocking member 200, and the second support frame 500 is hinged to a rotating member 300. Both the first support frame 400 and the second support frame 500 have an open state and a folded state. Abutment structures can be provided on both the rocking member 200 and the rotating member 300 to limit the opening angle of the first support frame 400 and the second support frame 500 in the open state. The chair fabric 600 is connected to the first support frame 400, and the first support frame 400 can drive the chair fabric 600 to open or fold. Four first support frames 400 can be provided, serving as supports for the chair body, and four second support frames 500 can also be provided, serving as supports for the chair legs, supporting the chair on the ground. When a user sits on the chair fabric 600, they can move the first support frame 400 and the rocking member 200 together relative to the base 100 around the rotation axis AY within a certain angle range by moving their body; they can also move the first support frame 400, the rocking member 200 and the base together relative to the rotating member 300 around the central axis AX to achieve 360-degree rotation.
