Description

Technical Field

[0001] The utility model relates to the field of folding chairs, in particular to a folding chair with a seat that can be folded and stowed in linkage. Background Art

[0002] With the development of society and the progress of the times, various venues have put forward higher requirements for existing folding chairs. Existing folding chairs are generally folding chairs with seats that move with the front and rear legs when opening and closing. Such seats cannot be folded when needed, resulting in a fixed aisle distance between two rows of seats, which is inconvenient for people to pass through and very inconvenient to use; there are also folding chairs with non-linked seats. When opening and closing, the seats do not move with the front and rear legs. When using, the seat status needs to be adjusted. After the whole row is placed, the consistency of the seats is not high, affecting the overall appearance of the venue. Utility Model Content

[0030] See also Figures 1 to 8 The utility model provides a folding chair with a foldable seat, comprising a front supporting foot 1, a rear supporting foot 2 hinged to the front supporting foot 1, a symmetrically arranged long connecting rod 4, and a seat 5 mounted between the two long connecting rods 4, wherein the front end of the long connecting rod 4 is hinged to the top of the rear supporting foot 2, and the rear end of the long connecting rod 4 is connected to the front supporting foot 1; the front end of the long connecting rod 4 is provided with a supporting baffle 401 extending toward the inside, the supporting baffle 401 is used to support the position-limiting seat 5, and the supporting baffle 401 and the long connecting rod 4 are an integrated structure. The rear end of the seat 5 is hinged to the long connecting rod 4, and the front end of the seat 5 is against the supporting baffle 401.

[0031] See also Figures 1 to 3 The rear end of the long connecting rod 4 is connected to the front supporting foot 1 through the short connecting rod 3, the upper end of the short connecting rod 3 is hinged on the front supporting foot 1, and the lower end of the short connecting rod 3 is hinged on the rear end of the long connecting rod 4. Among them, the length of the long connecting rod 4 is greater than that of the short connecting rod 3.

[0032] In some embodiments, Figures 1 to 4 As shown, the front support foot 1 is U-shaped, and the rear support foot 2 is hinged to the inner side of the front support foot 1 through the support rotation axis 6; the long connecting rod 4 and the rear support foot 2 are hinged to each other through the long connecting rod rotation axis 8. The long connecting rod 4, the seat 5 and the opposite end of the short connecting rod 3 are hinged to each other through the connecting rod rotation axis 9, and the short connecting rod 3 and the front support foot 1 are hinged to each other through the short connecting rod rotation axis 7.

[0033] In some embodiments, Figures 2 to 4As shown, a limit rod 11 is provided on the front support foot 1, and a first bayonet corresponding to the limit rod 11 is provided at the lower end of the short connecting rod 3, and the limit rod 11 is used to limit and support the short connecting rod 3; after the folding chair is unfolded, the first bayonet abuts against the limit rod 11. A limit protrusion 402 is provided at the rear end of the long connecting rod 4, and a second bayonet corresponding to the limit protrusion 402 is provided at the lower end of the short connecting rod 3, and the second bayonet and the first bayonet are respectively located on both sides of the end of the short connecting rod 3, and the limit protrusion 402 is used to limit the short connecting rod 3 from rotating over the long connecting rod 4; after the folding chair is folded, the second bayonet abuts against the limit protrusion 402.

[0034] In some embodiments, Figure 5 As shown, a cushion pad 10 is installed on the support baffle 401, and the cushion pad 10 is used to cushion the seat 5, which is beneficial to reduce the sound when the seat 5 contacts the support baffle 401 when it is turned over, and effectively protects the appearance of the seat 5. A back pad 12 is provided at the upper end of the front support foot 1 to increase the comfort of riding.

[0035] The use process of this folding seat is as follows:

[0036] When opening, first rotate the front support foot 1 and the rear support foot 2 apart, and the rear support foot 2 rotates around the support rotation axis 6; when the rear support foot 2 rotates, it drives the long connecting rod rotation axis 8 to move forward, and then drives the long connecting rod 4 to move forward; when the long connecting rod 4 moves forward, it drives the short connecting rod 3 to rotate around the short connecting rod rotation axis 7 through the connecting rod rotation axis 9; when the first bayonet on the short connecting rod 3 contacts the limiting pull rod 11, the unfolding action is completed. The seat 5 is mounted on the long connecting rod 4 through the connecting rod rotation axis 9 and the support baffle 401. When the row spacing is limited, the seat can be folded up in the open state of the seat to increase the row spacing, so that people can stand on the extra space of the folding chair to let others pass (such as Figure 8 shown).

[0037] like Figure 6 and Figure 7 As shown, when folding, first flip up the seat 5, then fold the rear supporting foot 2, the rear supporting foot 2 drives the long connecting rod 4 to move backward; the long connecting rod 4 drives the short connecting rod 3 to rotate around the short connecting rod rotating axis 7 through the connecting rod rotating axis 8, and the limiting protrusion 402 on the long connecting rod 4 limits the short connecting rod 3 from rotating beyond the long connecting rod 4. When the second bayonet of the short connecting rod 3 contacts the limiting protrusion 402, the folding action is completed.

[0038] The same and similar parts between the various embodiments in this specification can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0039] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
