Description

Technical Field

[0001] This utility model belongs to the field of folding seat technology, and in particular relates to a novel folding seat. Background Technology

[0002] Folding chairs are seats that can be reduced in size through a folding structure, making them easy to store, carry, and save space. They are suitable for various scenarios such as outdoor activities and temporary occasions, combining practicality and portability.

[0003] Existing folding chairs generally suffer from insufficient ease of operation. Most products require both hands to complete the folding or unfolding action, and the folded size is still relatively large, taking up a lot of space when stored and making it inconvenient for transportation. This needs to be improved. Therefore, a new type of folding chair is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a novel folding seat to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel folding seat, comprising: The frame is composed of multiple lightweight metal tubular support members connected by hinges to form a foldable back support and seat support frame. The frame can be folded inward by hinges to achieve the backrest and seat portion. The support legs are hinged to the bottom of the frame via connectors. They fold together with the frame when folded and form a stable triangular or polygonal support structure when unfolded. The locking device is integrated at the frame hinge connection and the connection between the support leg and the frame. It adopts a snap-on, pin-type or spring-loaded mechanical structure and automatically or manually triggers the lock when the seat is unfolded to prevent accidental folding. The handrails are connected to the frame via adjustable connectors.

[0006] Preferably, the back support and seat support of the frame adopt a double hinge design to achieve synchronous folding. After folding, the volume is reduced by more than 40% compared with traditional seats. The support legs are provided with a two-way hinge at the connection between the support legs and the frame, allowing the support legs to fold inward to be parallel to the seat.

[0007] Preferably, the support structure adopts a triangular reinforcing rib design, and cross metal rods are set at the key stress-bearing parts of the frame.

[0008] Preferably, the folding process can be completed with one hand, and the time from unfolding to folding is no more than 5 seconds. The overall thickness after folding is ≤15cm, and it can be stored upright or hung in the matching storage bag.

[0009] In summary, compared with the prior art, the beneficial effects of this utility model are: by setting up a frame, supporting legs, locking device, and armrests working together, the seat can be quickly folded / unfolded with one hand. After folding, it is compact in size, easy to store and transport, and highly practical. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1-4 This utility model provides a technical solution: A new type of folding seat includes: Frame 1 is composed of multiple lightweight metal tubular support members connected by hinges to form a foldable back support and seat support frame. The backrest and seat part of the frame 1 can be folded inward by hinges. Support leg 2 is hinged to the bottom of frame 1 via a connector. When folded, it retracts together with frame 1 and when unfolded, it forms a stable triangular or polygonal support structure. The locking device 3 is integrated at the hinge connection of the frame 1 and the connection between the support leg 2 and the frame 1. It adopts a snap-on, pin-on or spring-loaded mechanical structure and automatically or manually triggers the locking when the seat is unfolded to prevent accidental folding. Handrail 4 is connected to frame 1 via an adjustable connector.

[0014] The back support and seat support of frame 1 adopt a double hinge design to achieve synchronous folding. After folding, the volume is reduced by more than 40% compared with traditional seats. The support leg 2 is equipped with a two-way hinge at the connection with frame 1, allowing the support leg 2 to fold inward to be parallel to the seat.

[0015] The supporting structure adopts a triangular reinforcing rib design, and cross metal rods 5 are set at the key stress-bearing parts of frame 1.

[0016] The folding process can be completed with one hand, taking no more than 5 seconds from unfolded to folded. The overall thickness after folding is ≤15cm, and it can be stored upright or hung in the matching storage bag.

[0017] Working principle: Frame 1 consists of lightweight metal tubular support components and hinges forming the backrest and seat support frame. When unfolded, the user applies external force to rotate the backrest and seat outward around the hinges. The double-hinge design ensures synchronous unfolding. Support legs 2 are hinged to the bottom of frame 1 and are equipped with bidirectional hinges. When unfolded, the user rotates them outward until they contact the ground to form a stable support structure. Locking device 3 is automatically or manually triggered after the seat is fully unfolded. For example, a spring-loaded locking block springs into the positioning groove of frame 1 to lock frame 1 and support legs 2. Armrests 4 are connected to frame 1 through adjustable connectors and can be adjusted in height as needed. The support structure uses triangular reinforcing ribs and intersecting metal rods 5 to enhance stability. When folding, the user first manually unlocks the locking device 3, then applies external force to rotate the support leg 2 inward around the two-way hinge until it is parallel to the seat plate. Then, the frame 1 backrest and the seat plate fold inward around the hinge simultaneously. The entire folding process can be operated with one hand and takes no more than 5 seconds. After folding, the overall thickness is ≤15cm. It can be stored upright or hung in the matching storage bag, achieving quick unfolding and folding while ensuring stability and portability. in, Frame 1 Deployment: Frame 1 consists of multiple lightweight metal tubular support members connected by hinges, forming the backrest and seat support frame. During deployment, the user applies a slight external force, causing the backrest and seat to rotate outwards around the hinges until the desired angle is reached. The dual-hinge design ensures that the backrest and seat support deploy simultaneously, creating a stable seat profile. Support leg 2 unfolds: Support leg 2 is hinged to the bottom of frame 1 via a connector and is equipped with a two-way hinge. After frame 1 is unfolded, the user rotates support leg 2 outward until it contacts the ground and forms a stable triangular or polygonal support structure. The two-way hinge allows support leg 2 to rotate inward to be parallel to the seat plate when folded, and to be fixed at the ground contact position when unfolded; Locking device 3 is activated: Locking device 3 is integrated at the hinge connection of frame 1 and the connection between support leg 2 and frame 1. After the seat is fully extended, the snap-on, pin-type, or spring-loaded mechanical structure is automatically or manually activated to lock frame 1 and support leg 2 in the extended state, preventing accidental folding. For example, the spring-loaded locking block automatically springs into the positioning groove of frame 1 when support leg 2 is extended, achieving a secure lock. Triangular reinforcing ribs and intersecting metal rods 5: The support structure employs a triangular reinforcing rib design, with intersecting metal rods 5 installed at key stress points in frame 1 to enhance the stability and load-bearing capacity of the seat. This design ensures that the seat remains stable even when bearing heavy loads.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
