Description

Technical Field

[0001] This utility model belongs to the field of seating technology, specifically relating to a folding chair. Background Technology

[0002] Folding chairs are widely used in outdoor activities due to their portability and ease of storage. Traditional folding chairs typically fold using hinge mechanisms. To further reduce storage volume, detachable rods and connectors have been designed for disassembly and folding. However, after disassembly and folding, the overall structure is loose and messy, resulting in an insufficiently compact and neat storage volume. This not only makes them inconvenient to carry, but also makes it easy for components to be lost. During reassembly, it is difficult to quickly determine the assembly position of components, making disassembly and assembly time-consuming and laborious, thus affecting the user experience. Furthermore, additional storage bags are required to store the disassembled and folded components, increasing the number of accessories, making them prone to loss, and further complicating use. Summary of the Invention

[0003] This utility model addresses the aforementioned technical problems by providing a folding chair that is small in size, easy to assemble and disassemble, and requires no additional storage bag. The objective of this utility model is achieved through the following technical solution:

[0004] A folding chair includes a first support frame and a second support frame. The first support frame includes a first rod and a first connector, with a first elastic cord threaded through the first rod. The second support frame includes a second rod and a second connector, with a second elastic cord threaded through the second rod. Both the first and second support frames have a supported state and a folded state. When the first support frame is in the supported state, adjacent first rods are rigidly connected by the first connector. When the first support frame is in the folded state, multiple first rods are separated, arranged side by side, and flexibly connected by the first elastic cord. When the second support frame is in the supported state, adjacent second rods are rigidly connected by the second connector. When the second support frame is in the folded state, multiple second rods are separated, arranged side by side, and flexibly connected by the second elastic cord. A seat is installed between the first and second support frames. A backrest assembly is installed on the second support frame. The backrest assembly can detach from the second support frame and transform into a storage bag, which can accommodate the folded first and second support frames and the seat.

[0005] Preferably, the first member has three parts, namely a first horizontal support rod and two first diagonal support rods, and the first connector has two parts, which are respectively fixed to the two ends of the first horizontal support rod.

[0006] Preferably, the second member has five members, namely a second horizontal brace, two second diagonal braces, and two back braces; the second connector has two members, which are fixed to the two ends of the second horizontal brace respectively; the second diagonal brace is cross-hinged with the first diagonal brace on the same side.

[0007] Preferably, the seat is sewn between the first cross brace and the second cross brace; the backrest assembly is fitted onto the two back support rods.

[0008] Preferably, the backrest assembly includes a main backrest piece, with an inner lining piece sewn onto the back of the main backrest piece, and two sleeves sewn onto both sides of the inner lining piece, with the two back support rods respectively inserted into the sleeves on the same side.

[0009] Preferably, the main support piece is divided into an upper half and a lower half. The outer edge of the upper half is sewn with a first skirt hem, and the outer edge of the lower half is sewn with a second skirt hem. The first skirt hem and the second skirt hem are sewn with matching zippers. The upper half and the lower half are folded in half and connected and sealed by a zipper to form a storage bag.

[0010] Preferably, both the first and second skirts are sewn onto the back of the main support piece. The bottom of the second skirt has two through holes for the back support rod to pass through, and the two through holes are respectively aligned with the sleeve on the same side.

[0011] Preferably, a wrapping piece is sewn to the bottom of the seat surface, which can wrap the first and second support frames in their stored state; a bag piece is sewn to the wrapping piece, which, together with the extension piece, defines a storage bag; and a Velcro strap is sewn to the bottom of the seat surface to tie the wrapping piece.

The second horizontal insert is inserted into the corresponding end of the second horizontal support rod and fixed by rivets. The second oblique insert is inserted into the second oblique support rod on the same side, and the vertical insert is inserted into the back support rod on the same side.

[0014] Compared with the prior art, this utility model has the following technical effects: integrated storage, convenient and efficient. By designing the backrest component as a structure that can transform into a storage bag, the folding chair and the storage bag are integrated, eliminating the need to carry an additional storage bag. Utilizing elastic ropes threaded inside the rods, after the rigid connection of the connectors is released, multiple components are flexibly connected, preventing component loss and allowing for quick and easy identification of the rod assembly positions during assembly. When the folding chair is in use, the ball-head connectors achieve a rigid connection between the rods, and the elastic ropes provide tension, improving the stability of the connection between the rods and ensuring the structural strength and stability of the seat. The binding piece and storage bag at the bottom of the seat can be used to secure the folded support frame after folding, making storage more convenient. The storage bag also provides additional storage space when the seat is unfolded, increasing the product's practicality. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0023] See Figures 1-6This embodiment discloses a folding chair, including a first support frame and a second support frame. The first support frame includes a first rod and a first connector 13, with a first elastic rope threaded through the first rod. The second support frame includes a second rod and a second connector 23, with a second elastic rope threaded through the second rod. Both the first and second support frames have a supported state and a retracted state. When the first support frame is in the supported state, adjacent first rods are rigidly connected by the first connector 13. When the first support frame is in the retracted state, multiple first rods are separated, arranged side by side, and flexibly connected by the first elastic rope. When the second support frame is in the supported state, adjacent second rods are rigidly connected by the second connector. When the second support frame is in the retracted state, multiple second rods are separated, arranged side by side, and flexibly connected by the second elastic rope. Elastic ropes are threaded inside the rods of each support frame. When the rods are removed from the connectors, they form a flexible connection through the elastic ropes, preventing the rods from completely separating and effectively avoiding the risk of small components being lost during transportation or storage. During assembly, the natural tension of the elastic ropes guides adjacent rods to come together for splicing, achieving quick positioning and convenient assembly.

[0024] The first rod has three members: a first horizontal support rod 11 and two first diagonal support rods 12. There are two first connectors 13, which are fixed to the two ends of the first horizontal support rod 11 respectively. There is one first elastic rope, whose two ends are fixed in the two first diagonal support rods 12 respectively. The first connector 13 includes a first ball head 131, and a first horizontal insertion rod 132 and a first diagonal insertion rod 133 provided on the first ball head 131. The first horizontal insertion rod 132 is inserted into the corresponding end of the first horizontal support rod 11 and fixed by rivets. The first diagonal insertion rod 133 is inserted into the first diagonal support rod 12 on the same side.

[0025] The second member has five members: a second horizontal support rod 21, two second diagonal support rods 22, and two back support rods 24. Two second elastic ropes are provided, used to connect the second diagonal support rods 22 and the back support rods 24 on the same side, respectively. The two ends of the second elastic ropes are fixed inside the second diagonal support rods 22 and the back support rods 24 on the same side. Two second connecting members 23 are provided, respectively fixed to the two ends of the second horizontal support rod 21. The second diagonal support rod 22 is cross-hinged with the first diagonal support rod 12 on the same side. The second connecting member 23 includes a second ball head 231, and a second horizontal insert rod 232, a second diagonal insert rod 233, and a vertical insert rod 234 provided on the second ball head 231. The second horizontal insert rod 232 is inserted into the corresponding end of the second horizontal support rod 21 and fixed by rivets. The second diagonal insert rod 233 is inserted into the second diagonal support rod 22 on the same side, and the vertical insert rod 234 is inserted into the back support rod 24 on the same side. Ball-head connectors are used to achieve rigid connections between the members, ensuring the structural strength and stability in the supported state, and the insertion is convenient; the elastic rope inside the member can provide pre-tension in the supported state, making the insertion tighter and further enhancing the stability of the structure.

[0026] The backrest assembly is inserted into two back support rods 24. The backrest assembly includes a main backrest piece 41, with an inner lining piece 45 sewn onto the back of the main backrest piece 41. Two sleeves 451 are sewn onto both sides of the inner lining piece 45, and the two back support rods 24 are respectively inserted into the sleeves 451 on the same side. Both the main backrest piece 41 and the inner lining piece 45 are made of foldable material. The main backrest piece 41 is divided into an upper half and a lower half. A first skirt 42 is sewn onto the outer edge of the upper half, and a second skirt 43 is sewn onto the outer edge of the lower half. Zippers 44 are sewn onto the first skirt 42 and the second skirt 43. The upper half and the lower half are folded together and connected and sealed by the zipper 44 to form a storage bag. The first skirt 42 and the second skirt 43 are both sewn onto the back of the main backrest piece 41. Two through holes are opened at the bottom of the second skirt 43 for the back support rods 24 to pass through, and the two through holes are respectively aligned with the sleeves 451 on the same side. By optimizing the backrest component structure, integrated storage is achieved. The backrest component serves as a backrest when the folding chair is in use, and can be transformed into a dedicated storage bag when the folding chair is stored, greatly improving the integrity and convenience of the product.

[0027] The seat surface 31 is sewn between the first cross brace 11 and the second cross brace 21. A binding piece 32 is sewn onto the bottom of the seat surface 31, which can bind the first and second support frames in their folded state. A pocket piece 321 is sewn onto the binding piece 32, which, together with the extension piece, defines a storage pocket. A Velcro strap is sewn onto the bottom of the seat surface 31 to secure the binding piece 32. The seat surface 31, binding piece 32, and pocket piece 321 are all made of rollable material. When the folding chair is in use, the binding piece 32 serves as a storage function; when the folding chair is folded away, it can bind the first and second support frames, making storage more convenient and compact.
