Description

Technical Field

[0001] This application relates to the technical field of tourism products, and in particular to a folding chair. Background Technology

[0002] Folding chairs are widely used in outdoor activities such as picnics and camping, as well as in various temporary venues, due to their ease of storage and portability.

[0003] Traditional folding chairs typically employ simple hinged rod structures to achieve their folding function. Some folding chairs can only fold down either the seat or the backrest, making it difficult to achieve a compact overall size when folded, resulting in a still relatively large volume. Furthermore, many traditional folding chairs lack dedicated storage compartments, failing to meet people's needs for placing items. Even those that do have storage areas often rely on additional shelves, which not only increases structural complexity, making manufacturing more complicated and costly, but also prevents the chair from folding down simultaneously with the main body, increasing storage difficulty and space consumption. Utility Model Content

[0004] In order to overcome the aforementioned technical problems, this application provides a folding chair.

[0005] The folding chair provided in this application adopts the following technical solution: A folding chair includes two symmetrically arranged leg frames, a seat disposed between the two leg frames and capable of being folded laterally, and a backrest disposed on the leg frames and capable of being folded vertically. The side of the seat is connected to a storage unit. When the seat is folded laterally, the storage unit and the leg frames fold simultaneously. When the seat is unfolded laterally, the storage unit and the leg frames unfold simultaneously.

[0006] By adopting the above technical solution, the seat can be folded horizontally and the backrest can be folded vertically, making the folding chair more compact when stored, reducing storage space, and making it easier to carry and store. The storage compartment provides users with convenient storage without the need for additional tools, and the storage compartment can be folded and unfolded synchronously with the seat.

[0007] Preferably, the chair seat includes two opposing chair seat frames and a seat portion and a linkage assembly connected to the chair seat frames. The linkage assembly includes a support member and a first and second linkage that are cross-hinged. The top ends of the first and second linkages are respectively hinged to the two chair seat frames, and the bottom ends of the first and second linkages are respectively hinged to the two leg frames. The support member is a sliding connection structure of the linkage assembly, and the support member is used to form a support so that the unfolded chair seat can be more stably stressed.

[0008] By adopting the above technical solution, the chair seat can be folded laterally. With the help of the sliding connection structure of the linkage assembly, the chair seat frame can be folded smoothly, making the folding chair more compact when stored, reducing storage space, and making it easier to carry and store. The folding operation is also smooth. At the same time, the lateral folding of the chair seat can drive the storage parts and the support frame to fold simultaneously, and they can also be unfolded simultaneously, providing users with convenient storage.

[0009] Preferably, a connector is fixed at the bend of the seat frame, the connector is hinged to the leg frame, and the end of the connector away from the seat frame is fixedly connected to the storage component.

[0010] By adopting the above technical solution, the seat frame is connected to the leg frame and storage unit through the connector. When the seat is folded down, the storage unit can be folded down synchronously with the leg frame, making the folding chair more compact and easier to carry and store. When the seat is unfolded, the storage unit can also unfold synchronously with the leg frame, providing convenience for users to store items.

[0011] Preferably, the backrest includes two fixing parts respectively fixed to the two support leg frames, two connecting parts respectively hinged to the two fixing parts, and a backrest disposed between the two connecting parts.

[0012] By adopting the above technical solution, the backrest of the folding chair can be folded vertically through the hinge between the connecting part and the fixed part, ensuring that the backrest will not be obstructed when the chair seat is folded horizontally, so that the chair seat can be folded smoothly.

[0013] Preferably, the top end of the connecting part is formed with a rearwardly inclined portion, and the backrest is fixed to the rearwardly inclined portion.

[0014] By adopting the above technical solution, the reclining part can make the backrest tilt backward, conforming to the curve of the human back, and improving the user's comfort when leaning against the backrest.

[0015] Preferably, an elastic element is embedded inside the connecting part, and the abutting part of the elastic element abuts against the inner sidewall of the fixing part.

[0016] By adopting the above technical solution, the abutting part of the elastic element abuts against the inner wall of the fixing part, which can increase the friction between the connecting part and the fixing part, making it difficult for the backrest to flip back after it has been flipped upwards.

[0017] Preferably, the support leg frame has a handrail portion formed thereon, and the periphery of the handrail portion is covered with a soft pad.

[0018] By adopting the above technical solutions, the armrests make it easier for users to place their arms, improving the comfort of use; the soft padding made of soft material covers the armrests, making it more comfortable for users to touch.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. The seat can be folded horizontally and the backrest can be folded vertically, making the folding chair more compact when stored, reducing storage space, and making it easier to carry and store; the storage compartment provides users with convenient storage without the need for additional tools, and the storage compartment can be folded and unfolded synchronously with the seat. 2. The seat frame is connected to the leg frame and storage unit via connectors. When the seat is folded down, the storage unit and the leg frame fold down simultaneously, making the folding chair more compact and easier to carry and store. When the seat is unfolded, the storage unit also unfolds simultaneously with the leg frame, providing convenience for users to store their belongings. 3. The backrest of the folding chair can be folded vertically through the hinge between the connecting part and the fixed part, ensuring that the backrest will not obstruct the horizontal folding of the chair seat, so that the chair seat can be folded smoothly.

[0030] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0031] This application discloses a folding chair.

[0032] Example 1 Reference Figure 1 and Figure 2 The folding chair includes two symmetrically arranged leg frames, a seat that can be folded laterally between the two leg frames, and a backrest that can be folded vertically on the leg frames. At least one storage unit is attached to the seat, located on the side of the seat. When the seat is folded laterally, the storage unit and the leg frames fold simultaneously, making the folding chair more compact when stored, facilitating carrying and storage. When the seat is unfolded laterally, the storage unit and the leg frames unfold simultaneously, giving the folding chair a storage function and improving its ease of use.

[0033] The leg frame includes two longitudinally arranged leg sections 1. The bottom of the leg section 1 supports the ground and serves to support the entire folding chair. To ensure the stability of the support, the bottom of the leg section 1 can be designed with a structure with an anti-slip pad or foot cover. The anti-slip pad can be made of rubber, and the foot cover can be made of plastic to increase the friction with the ground, thereby effectively reducing the sliding of the folding chair.

[0034] The tops of the two support legs 1 are bent longitudinally to form armrests 11, which provide a convenient place for the user's arms and improve comfort. A soft pad 111, made of a soft material such as sponge, is fitted onto the armrests 11 using an interference fit. This ensures the pad is securely fixed and provides a more comfortable feel for the user. A reinforcing part 12, located below the armrests 11, is fixedly connected between the two support legs 1 of the same support frame. The reinforcing part 12 enhances the overall strength of the support frame, making it more stable. Furthermore, the two support legs 1 in the same longitudinal direction are arranged in a V-shape, and the two support legs 1 in the same transverse direction are also arranged in a V-shape. This V-shape arrangement allows the folding chair to support itself more stably, greatly improving its stability.

[0035] Reference Figure 2 and Figure 3 The backrest includes two fixing parts 2 respectively fixed to two support legs, two connecting parts 21 respectively hinged to the two fixing parts 2, and a backrest 22 disposed between the two connecting parts 21. In this embodiment, the two fixing parts 2 are located in the same lateral direction, and the two support legs are located between the two fixing parts 2. The cross-section of the fixing part 2 is U-shaped and its opening faces the object being placed. The bottom end of the connecting part 21 extends into the fixing part 2 and is hinged to the fixing part 2, so that the connecting part 21 can drive the backrest 22 to fold towards the armrest 11 or unfold away from the armrest 11. When the backrest 22 is folded, the two armrests 11 are limited between the two connecting parts 21. The backrest 22 is a flexible backrest, for example, it can be made of flexible materials such as fabric or leather, so that the backrest 22 will not obstruct the folding of the seat laterally, ensuring the smooth folding of the seat.

[0036] The top of the connecting part 21 is formed with a backward tilting part 211, and the backrest 22 is fixed on the backward tilting part 211. When the connecting part 21 is flipped upward until the fixing part 2 limits the connecting part 21, the backward tilting part 211 can make the backrest 22 tilt backward. This backward tilting design conforms to the curve of the human back and improves the comfort of the user when leaning back.

[0037] To increase the friction between the connecting part 21 and the fixing part 2, making it less likely for the backrest 22 to flip backward after being flipped upward, an elastic element is embedded inside the connecting part 21. In this embodiment, the elastic element is a spring sheet 212 with a V-shaped cross-section. One end of the spring sheet 212 has an abutment portion 213 formed therein. A through hole 214 is formed on the surface of the connecting part 21, and the abutment portion 213 of the spring sheet 212 passes through the through hole 214 and extends to the outside of the connecting part 21. When the backrest 22 is flipped upward, the abutment portion 213 of the spring sheet 212 abuts against the inner wall of the fixing part 2, generating friction. The side of the fixing part 2 is bent to accommodate the abutment portion 213, which allows the connecting part 21 to flip upward more smoothly.

[0038] Reference Figure 1 and Figure 4 The chair seat includes two opposing chair frame frames 3, a chair seat part 31 fixed between the two chair frame frames 3, and two sets of connecting rod assemblies arranged front to back and connected between the two chair frame frames 3; the chair seat part 31 can be made of flexible materials, such as cloth or mesh, which ensures the user's sitting comfort without hindering the lateral folding of the chair seat.

[0039] Reference Figure 4 and Figure 5 The chair seat frame 3 has a U-shaped cross-section, and the openings of the two chair seat frames 3 are positioned opposite each other. When there is one item, one chair seat frame 3 is hinged between the two legs 1 of the same leg frame, and the other chair seat frame 3 has a connector 32 at each of its two bends. The two connectors 32 are respectively hinged to the two legs 1 of the corresponding leg frames. The end of the connector 32 away from the chair seat frame 3 is connected to the item to achieve the installation of the item. When there are two items, connectors 32 are provided at the bends of both chair seat frames 3 to achieve the installation of both items.

[0040] The linkage assembly includes a first link 33, a second link 34, and a support member. The first link 33 and the second link 34 are staggered and intersecting, and are hinged at the intersection. Two support legs 1 located in the same lateral direction are respectively hinged to the bottom ends of the first link 33 and the second link 34. The top end of the first link 33 is hinged to the end of the side arm of the seat frame 3, and the top end of the second link 34 is hinged to the end of the side arm of another seat frame 3. The support member is a sliding connection structure of the linkage assembly. The support member is used to form a triangular support for the unfolded folding chair, so that the unfolded folding chair can be more stably stressed.

[0041] The support includes connecting strips 35 and connecting pieces 37. There are two connecting strips 35, which are respectively hinged to the connection between the first connecting rod 33 and the seat frame 3 and the connection between the second connecting rod 34 and the seat frame 3. There are two connecting pieces 37, which are respectively fixed to the side of the first connecting rod 33 and the second connecting rod 34 that are close to each other. The connecting pieces 37 have elongated holes 371, thereby forming sliding channels on the first connecting rod 33 and the second connecting rod 34. The bottom ends of the two connecting strips 35 are formed with sliding parts 38, which are slidably connected to the corresponding sliding channels.

[0042] When the seat is folded laterally, the sliding part 38 slides within the elongated hole 371, causing the first connecting rod 33 and the second connecting rod 34 to rotate relative to each other, thus achieving the lateral folding of the seat. When the seat is fully unfolded, the sliding part 38 is limited to the end of the elongated hole. At this time, a triangular support is formed between the first connecting rod 33, the second connecting rod 34, and the connecting strip 35, allowing the folding chair to bear force more stably. Furthermore, the connection points between the side arm of the seat frame 3 and the first connecting rod 33, and between the side arm of the seat frame 3 and the second connecting rod 34, all form a certain angle. This angle design helps the connecting rod assembly to function better during unfolding and folding, making the folding and unfolding operations smoother.

[0043] Reference Figure 5 and Figure 6 One end of the connector 32 is fixedly fitted onto the bend of the chair frame 3, and the end of the connector 32 away from the chair frame 3 is fixedly connected to the storage component. Through the connector 32, the storage component can be folded down synchronously with the chair. In this embodiment, two storage components are provided: a tabletop 4 and a storage frame 41. In other embodiments, both storage components can be either a tabletop 4 or a storage frame 41. The tabletop 4 allows users to conveniently place items such as teacups and books. The surface of the tabletop 4 is provided with a placement groove 42 that adapts to the shape of the container. The placement groove 42 can be designed according to the shape of common containers, such as round or square, to accommodate different types of containers.

[0044] The storage frame 41 can be used to tie bags, providing users with more storage options. Bags containing ice can also be tied to the storage frame 41, allowing users to easily add ice to their drinks when using the folding chair outdoors. Furthermore, when the folding chair is unfolded, both the tabletop 4 and the storage frame 41 are tilted downwards towards the support legs 1. This design makes items placed on the tabletop 4 and storage frame 41 less likely to slip, further improving the stability and safety of the storage.

[0045] Reference Figure 5 and Figure 7During the folding process of the folding chair, when the seat begins to fold horizontally, the sliding part 38 at the bottom of the connecting strip 35 slides in the opposite direction within the elongated hole 371 of the connecting piece 37, causing the first connecting rod 33 and the second connecting rod 34 to rotate relative to each other, causing the opening of the seat frame 3 to gradually flip upwards; the bent part of the seat frame 3 is hinged to the leg part 1 of the support frame through the connecting piece 32, and the connecting piece 32 is also connected to the storage piece, so the seat frame 3 will cause the storage piece to fold synchronously with the support frame during the folding process. For the backrest, the connecting part 21 is first rotated towards the armrest part 11. At this time, the connecting part 21 rotates around the hinge point with the fixing part 2, and finally the backrest 22 is folded to the position close to the armrest part 11, and the two armrest parts 11 are limited between the two connecting parts 21, completing the vertical folding of the backrest.

[0046] The implementation principle of a folding chair according to this application embodiment is as follows: Through a unique structural design, the folding chair achieves lateral folding of the seat and vertical folding of the backrest, making it more compact when folded, reducing storage space, and facilitating carrying and storage. Simultaneously, the inclusion of storage compartments provides users with convenient storage without the need for additional tools. The ingenious connection and cooperation between the various components ensures the chair's stability and smooth folding and unfolding operations. Compared to traditional folding chairs, it significantly improves folding functionality, storage convenience, and user comfort, meeting diverse user needs and enhancing the practicality and market competitiveness of folding chairs.

[0047] Example 2 Reference Figure 8 and Figure 9 The difference between this embodiment and Embodiment 1 lies in the support components. In this embodiment, the support components include support bars 39 and connecting sleeves 36 movably fitted onto the support legs 1. Two support bars 39 are provided, each hinged to the connection between the first connecting rod 33 and the seat frame 3, and the second connecting rod 34 and the seat frame 3, respectively. The periphery of the connecting sleeve 36 is hinged to the bottom end of the support bar 39. Preferably, the two support bars 39 located on the same transverse direction are staggered to make the folding chair more compact when stored, reducing storage space. The first connecting rod 33 and the second connecting rod 34 rotate relative to each other, causing the support bars 39 to slide the connecting sleeves 36 upwards, thereby achieving the transverse folding of the seat.

[0048] A limiting member 361 is fixedly inserted on the leg part 1 of the support frame, and both ends of the limiting member 361 extend outside the leg part 1. When the chair seat is fully unfolded laterally, both ends of the limiting member 361 abut against the bottom surface of the connecting sleeve 36 to limit the connecting sleeve 36. At this time, a triangular support is formed between the side arm of the chair seat frame 3, the support bar 39 and the leg part 1, so that the folding chair can be more stably stressed.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
