Description

Technical Field

[0001] This utility model relates to the field of folding chair technology, and in particular to a fully folding Krmit chair. Background Technology

[0002] Currently, Kermit chairs are mainly used for outdoor camping. They generally consist of a support frame and a support layer. The support frame is foldable, and the support layer is made of flexible Oxford cloth and is sewn onto the support frame so that one can sit on the support layer. Although the Kermit chair described in utility model patent CN217309604U is foldable, the front and rear legs are bent outwards, resulting in a large volume after folding, which is not convenient for storage. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a fully foldable Kermit chair that can be quickly folded and occupies a small volume when folded, making it easy to store.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] This utility model provides a fully folding Kermit chair, including armrest tubes, backrest tubes, seat tubes, front leg tubes, rear leg tubes, and front and rear cross tubes that are rotatably connected to each other and arranged in a cross configuration. The lower end of the front cross tube is rotatably connected to the lower end of the front leg tube, and the upper end of the front cross tube is rotatably connected to the front end of the seat tube. The upper end of the rear cross tube is rotatably connected to the upper end of the backrest tube, and the lower end of the rear cross tube is rotatably connected to the rear end of the seat tube. The lower end of the backrest tube is rotatably connected to the rear end of the seat tube. Both the front and rear leg tubes are straight tubes. The upper ends of the front and rear leg tubes are rotatably connected to the armrest tubes, and the seat tube is rotatably connected to the front leg tubes. The rear leg tubes are connected to the seat tubes via a locking protrusion to ensure stable support when unfolded.

[0006] Furthermore, the card boss has two support portions spaced apart and a limiting portion fixedly connected between the two support portions. The limiting portion is provided with a first hinge hole, and the two support portions are provided with a second hinge hole at one end away from the limiting portion. The seat tube is hinged to the first hinge hole to form a first hinge point, and the rear leg tube is hinged to the second hinge hole to form a second hinge point.

[0007] Furthermore, the limiting part is provided with an inclined surface for abutting against the rear foot tube.

[0008] Furthermore, the upper end of the front cross tube is hinged to the front end of the seat tube via a first connector.

[0009] Furthermore, the first connector is a crescent-shaped connector; the front leg tube and the seat tube are respectively arranged parallel to each other.

[0010] Furthermore, the lower ends of the front cross tube and the front foot tube, as well as the lower ends of the back tube and the rear of the seat tube, are rotatably connected by second connectors.

[0011] Furthermore, the second connector is a U-shaped connector.

[0012] Furthermore, the upper end of the rear cross tube and the upper end of the back tube, as well as the lower end of the rear cross tube and the rear end of the seat tube, are respectively hinged by a third connector; the back tubes are arranged parallel to each other.

[0013] Furthermore, the third connector is an L-shaped connector.

[0014] Furthermore, the handrail tube has an adjustable connector, and the upper ends of the front leg tube and the rear leg tube are respectively hinged to the adjustable connector.

[0015] The technical solution provided by this utility model has the following beneficial effects:

[0016] The armrest tube, back tube, seat tube, front leg tube, rear leg tube, front cross tube, and rear cross tube work together to achieve quick folding or collapsing. When folded, neither the front nor rear leg tube bends outward, resulting in a small volume when folded and easy to store. When unfolded, the two cross-shaped rear cross tubes form a back support.

[0029] like Figures 1 to 3 As shown, the fully-converged Krmit chair of this embodiment includes two armrest tubes 1, a backrest tube 2, a seat tube 3, a front leg tube 4, a rear leg tube 5, and two front cross tubes 6 and a rear cross tube 7 that are rotatably connected to each other and arranged in a cross configuration. The two front leg tubes 4, the rear leg tubes 5, the seat tube 3, and the backrest tube 2 are arranged in parallel to each other.

[0030] The lower ends of the two front cross tubes 6 are rotatably connected to the lower ends of the corresponding front leg tubes 4, and the upper ends of the two front cross tubes 6 are rotatably connected to the front end of the corresponding seat tube 3. The upper ends of the two rear cross tubes 7 are rotatably connected to the upper ends of the corresponding back tubes 2, and the lower ends of the two rear cross tubes 7 are rotatably connected to the rear end of the corresponding seat tube 3. The lower ends of the two back tubes 2 are rotatably connected to the rear of the corresponding seat tube 3. The two front leg tubes 4 and the rear leg tubes 5 are both straight tubes. The upper ends of the two front leg tubes 4 and the rear leg tubes 5 are rotatably connected to the corresponding armrest tubes 1. The two seat tubes 3 are rotatably connected to the corresponding front leg tubes 4, and the two rear leg tubes 5 are connected to the corresponding seat tubes 3 through the locking bosses 8 to ensure stable support when unfolded.

[0031] In this embodiment, as Figure 1 and Figure 6 As shown, the upper ends of the two front cross tubes 6 are respectively hinged to the front end of the corresponding seat tube 3 through the first connector 9, and the specific first connector 9 is a crescent-shaped connector.

[0032] like Figure 1 and Figure 7 As shown, the lower ends of the two front cross tubes 6 and the lower ends of the corresponding front foot tubes 4, as well as the lower ends of the two back tubes 2 and the rear parts of the corresponding seat tubes 3, are rotatably connected by the second connector 10, and the specific second connector 10 is a U-shaped connector.

[0033] like Figure 1 and Figure 8 As shown, the upper end of the rear cross tube 7 and the upper end of the back tube 2, as well as the lower end of the rear cross tube 7 and the rear end of the seat tube 3, are respectively hinged by a third connector 11, and the specific third connector 11 is an L-shaped connector.

[0034] In practice, the upper ends of the two front cross tubes 6 are respectively hinged to one end of the corresponding crescent-shaped connector, and the other ends of the two crescent-shaped connectors are respectively hinged to the front end of the corresponding seat tube 3.

[0035] The rear parts of the two seat tubes 3 are respectively fixed with first U-shaped connectors, and the ends of the two first U-shaped connectors opposite to the seat tubes 3 are respectively hinged to the lower ends of the corresponding back tubes 2.

[0036] The lower ends of the two front foot tubes 4 are respectively hinged to one end of the corresponding second U-shaped connector, and the other ends of the two second U-shaped connectors are respectively hinged to the lower end of the corresponding front cross tubes 6.

[0037] The upper and lower ends of the two rear cross tubes 7 are respectively hinged to one end of the corresponding L-shaped connector, and the upper ends of the two back tubes 2 and the rear ends of the two seat tubes 3 are respectively hinged to the other end of the corresponding L-shaped connector.

[0038] Through the coordinated operation of armrest tube 1, backrest tube 2, seat tube 3, front leg tube 4, rear leg tube 5, front cross tube 6, and rear cross tube 7, the entire fully folding Kermit chair can be quickly folded or stowed, and the front leg tube 4 and rear leg tube 5 do not bend outwards after folding. Thus, the folded chair... Figure 4 The small footprint shown makes it easy to store.

[0039] When unfolded, the two intersecting rear cross tubes 7 can form as follows: Figure 1 The back support shown.
