[0027] As described in the background section, current folding chairs typically use a sliding mechanism between the leg tube and the support tube to achieve overall unfolding and folding. However, this method is prone to slippage and jamming, resulting in an unsmooth unfolding and folding mechanism. Furthermore, the leg tube is susceptible to damage from long-term friction and impact, which to some extent reduces the user experience.

[0028] Based on this, please refer to Figures 1-6 This utility model provides a folding chair frame 100 and a folding chair, which effectively improves the aforementioned technical problems. Specifically, it allows for easy unfolding and folding, the unfolding and folding process is smooth, and the surface of the legs is not easily damaged, thus improving the user experience. The folding chair frame 100 and the folding chair will be described in detail below.

[0029] This embodiment provides a folding chair (not shown in the figure). The folding chair includes a folding chair frame 100 and a chair cover. The chair cover is disposed on the folding chair frame 100 so that it provides support for the user's buttocks, back or legs when using the folding chair.

[0030] Please refer to Figures 1-3 , Figure 1 This is a schematic diagram of the folding chair frame 100 provided in this embodiment in its first unfolded state. Figure 2 This is a schematic diagram illustrating the folding process of the folding chair frame 100 provided in this embodiment. Figure 3 This is a schematic diagram of the folding chair frame 100 provided in this embodiment in its folded state.

[0031] Combination Figures 1-3The folding chair frame 100 includes a front leg 10, a rear leg 20, a support tube 30, and a flipping element 40. The rear leg 20 is hinged to the front leg 10. One end of the support tube 30 is hinged to one of the front leg 10 and the rear leg 20, and the other end is hinged to the flipping element 40. The flipping element 40 is hinged to the other of the front leg 10 and the rear leg 20. The flipping element 40 is used to rotate relative to the front leg 10 under the action of an external force, so as to drive the rear leg 20 to rotate relative to the front leg 10 through the support tube 30; or, to rotate relative to the rear leg 20, so as to drive the front leg 10 to rotate relative to the rear leg 20 through the support tube 30.

[0032] As is easily understood, during use, by flipping the flipping component 40, the support tube 30 moves along with it as it rotates relative to the front leg 10 or the rear leg 20. This movement, via the support tube 30, drives the rear leg 20 to rotate relative to the front leg 10, thus enabling the overall unfolding and folding of the folding chair frame 100. The operation is convenient and quick, the unfolding and folding process is smooth, and compared to existing methods using sliding components, the surface of the leg tubes is less prone to damage, improving the user experience. Furthermore, after the folding chair frame 100 is unfolded, the support tube 30 also supports the front leg 10 and the rear leg 20, improving stability during use.

[0033] It should be noted that, specifically in this embodiment, the support tube 30 is hinged to the rear leg 20, and the flipping member 40 is hinged to the front leg 10; of course, in other embodiments, the support tube 30 may also be hinged to the front leg 10, while the flipping member 40 may be hinged to the rear leg 20.

[0034] Combination Figure 2 It should be noted that during folding, the flipping component 40 can be rotated in direction A, which can also be understood as clockwise rotation. In this way, under the action of the support tube 30, the rear leg 20 is also rotated in direction A, so that the front leg 10 and the rear leg 20 are folded together. Figure 3 The shown configuration saves space. Of course, when it needs to be unfolded, the rotating component 40 is rotated in the opposite direction to direction A, which can also be understood as a counterclockwise rotation.

[0035] Please refer to Figure 4 , Figure 4 for Figure 3 A magnified view of a section at point E in the middle, combined with Figure 3 and Figure 4A slot 41 is provided on one side of the flip-up component 40. When the folding chair frame 100 is in the unfolded state, the slot 41 engages with the tube wall of the front leg 10 or the rear leg 20. Specifically, in this embodiment, since the flip-up component is located on the front leg 10, the slot 41 engages with the tube wall of the front leg 10; of course, in other embodiments, the slot 41 can also engage with the tube wall of the rear leg 20.

[0036] In other words, after the folding chair frame 100 is unfolded, the flip-up component 40 is snapped and fixed to the tube wall of the front leg frame 10, which prevents the flip-up component 40 from shaking when the folding chair is unfolded and used, and further improves the stability when unfolded and used.

[0037] Combination Figure 1 Specifically, the front leg 10 includes a first front leg tube 11, a second front leg tube 12, and a first fixing tube 13, with the first front leg tube 11 and the second front leg tube 12 respectively connected to both ends of the first fixing tube 13; the rear leg 20 includes a first rear leg tube 21, a second rear leg tube 22, and a second fixing tube 23, with the first rear leg tube 21 and the second rear leg tube 22 respectively connected to both ends of the second fixing tube 23; the first front leg tube 11 is hinged to the first rear leg tube 21, and the second front leg tube 12 is hinged to the second rear leg tube 22. The end of the first rear leg tube 21 away from the second fixing tube 23, the support tube 30, the flipping member 40, and the first front leg tube 11 are hinged in sequence.

[0038] It should be noted that in this embodiment, the number of the flipping component 40 and the support tube 30 is specifically one, and it cooperates with the first front leg tube 11 and the first rear leg tube 21. Of course, in other embodiments, the flipping component 40 and the support tube 30 can also cooperate with the second front leg tube 12 and the second rear leg tube 22. That is, the end of the second rear leg tube 22 away from the second fixed tube 23, the support tube 30, the flipping component 40, and the second front leg tube 12 are sequentially hinged. In addition, the number of the flipping component 40 and the support tube 30 can also be two. That is, the folding chair frame 100 is provided with flipping components 40 and support tubes 30 on opposite sides, which can cooperate with the corresponding front leg tubes and rear leg tubes, thereby further improving the operational efficiency of the folding and unfolding process and enhancing the overall structural stability of the chair frame.

[0039] Optionally, the first front leg tube 11, the first fixing tube 13, and the second front leg tube 12 are U-shaped tubes formed integrally or detachably. Similarly, the first rear leg tube 21, the second fixing tube 23, and the second rear leg tube 22 are also U-shaped tubes formed integrally or detachably.

[0040] Additionally, it should be noted that when the folding chair frame 100 is in the unfolded state, the rear leg frame 20 can be used as a seat frame. That is, the seat fabric can be placed on the first rear leg tube 21, the second rear leg tube 22, and the second fixing tube 23 to support the user's buttocks and legs.

[0041] Therefore, to improve the support strength of the rear leg 20 during use, the folding chair frame 100 also includes a reinforcing member 91, the two ends of which are connected to the first rear leg tube 21 and the second rear leg tube 22, respectively. Specifically, in this embodiment, the reinforcing member 91 is located at the end of the first rear leg tube 21 or the second rear leg tube 22 away from the second fixing tube 23, so that it can cooperate with the second fixing tube 23 to form a quadrilateral structure, thereby improving the support effect for the user's buttocks and legs.

[0042] It should be noted that the number of reinforcing members 91 in this embodiment is one. Of course, in other embodiments, the number of reinforcing members 91 can also be multiple, such as two or three, to further improve the support strength.

[0043] Please continue to combine Figure 1 To reduce leg pressure and improve user comfort when using a folding chair, the folding chair frame 100 in this embodiment also includes a footrest 50, which is rotatably connected to the rear leg frame 20.

[0044] Combination Figure 2 When folding, rotating the footrest 50 relative to the rear leg 20 along direction C (counter-clockwise) reduces the folded volume of the chair frame 100, saving space. Conversely, when unfolding, rotating the footrest 50 in the opposite direction to C (clockwise) reduces the chair frame's volume.

[0045] Specifically, the footrest 50 includes a first footrest tube 51, a second footrest tube 52, and a first connecting tube 53. The first footrest tube 51 and the second footrest tube 52 are respectively connected to both ends of the first connecting tube 53. The end of the first footrest tube 51 away from the first connecting tube 53 is hinged to the first rear footrest tube 21, and the end of the second footrest tube 52 away from the second connecting tube 73 is hinged to the second rear footrest tube 22.

[0046] To facilitate the assembly of the footrest tube, rear leg tube, and support tube 30, and to improve the compactness and stability of the overall structure, in this embodiment, the folding chair frame 100 also includes a connector 92. The first rear leg tube 21 and the second rear leg tube 22, which are away from the second fixed tube 23, are both fixedly provided with the connector 92. The first footrest tube 51 and one of the support tubes 30 are hinged to one of the connectors 92, and the second footrest tube 52 and the other support tube 30 are hinged to the other connector 92.

[0047] Further, please refer to Figure 5 , Figure 5 This is a structural diagram of the folding chair frame provided in this embodiment in its second unfolded state, combined with... Figure 5 To improve the support stability of the footrest 50, the folding chair frame 100 also includes a footrest support frame 60, which is rotatably connected to the footrest 50. It is easy to understand that when the folding chair frame 100 is in the unfolded state, the footrest support frame 60 can contact the ground or other supporting platform, thereby supporting the footrest 50 and further improving user comfort.

[0048] Combination Figure 2 When folding, rotating the footrest support 60 relative to the footrest 50 along direction B (counter-clockwise) reduces the folded volume of the chair frame 100, saving space. Conversely, when unfolding, rotating the footrest support 60 in the opposite direction (clockwise) is sufficient.

[0049] Please continue to combine Figure 1 The folding chair frame 100 also includes a backrest frame 70, which is rotatably connected to the rear leg frame 20. By setting the backrest frame 70, support can be provided for the user's back.

[0050] Specifically, the backrest frame 70 includes a first backrest tube 71, a second backrest tube 72, and a second connecting tube 73. The first backrest tube 71 is hinged to the first rear leg tube 21, and the second backrest tube 72 is hinged to the second rear leg tube 22. The two ends of the second connecting tube 73 are connected to the first backrest tube 71 and the second backrest tube 72, respectively, and the second connecting tube 73 is located at the end of the first backrest tube 71 away from the first rear leg tube 21. Understandably, the second connecting tube 73 can strengthen the tubing and improve the overall structural strength of the backrest frame 70.

[0051] It should be noted that in this embodiment, there is one second connecting pipe 73. Of course, in other embodiments, there may be multiple second connecting pipes 73, such as two or three, which can further enhance the structural strength and support stability.

[0052] Furthermore, the folding chair frame 100 also includes armrests 94, which slide in conjunction with the front leg frame 10 and are hinged to the backrest frame 70. By simultaneously sliding the armrests 94 with the front leg frame 10 and hinged to the backrest frame 70, a linkage structure is formed. This allows the armrests 94 and the backrest frame 70 to rotate simultaneously under the action of the flipping component 40, and also enables the armrests 94 to slide with the front leg frame 10, achieving synchronized folding and unfolding, further improving ease of use and folding / unfolding efficiency.

[0053] For details, please refer to Figure 6 , Figure 6 This is a structural schematic diagram of the folding chair frame provided in this embodiment from another perspective, combined with... Figure 1 and Figure 6 The bottom of the handrail 94 is provided with a slide groove 941, and the top of the front bracket 10 is slidably disposed in the slide groove 941.

[0054] Specifically, in this embodiment, there are two armrests 94. One armrest 94 is hinged to both the first front leg tube 11 and the first backrest tube 71, forming a quadrilateral structure between the first front leg tube 11, the armrest 94, the first backrest tube 71, and the first rear leg tube 21. The other armrest 94 is hinged to both the second front leg tube 12 and the second backrest tube 72, forming a quadrilateral structure between the second front leg tube 12, the armrest 94, the second backrest tube 72, and the second rear leg tube 22. Thus, under the flipping action of the flipping member 40, the two quadrilateral structures located on both sides of the folding chair frame 100 can be linked together, thereby quickly and conveniently realizing the folding and unfolding operation.

[0055] Please continue to combine Figure 1 To enhance the functionality of the folding chair, the folding chair frame 100 also includes a push handle 80 and wheels 95. The push handle 80 is rotatably connected to the end of the backrest frame 70 away from the rear leg frame 20; the wheels 95 are located at the end of the rear leg frame 20 near the backrest frame 70.

[0056] By installing wheels 95 on the rear leg frame 20 and a push handle 80 on the backrest frame 70, the folding chair can function as a trolley. Specifically, with the folding chair frame 100 in the unfolded state, the footrest 50 and footrest support frame 60 are folded down. At this time, the user can directly hold the push handle 80, and with the help of the wheels 95, the entire folding chair can be moved, saving time and effort and further improving ease of use.

[0057] In addition, in the folding chair frame 100 Figure 1In the shown configuration, the backrest frame 70 can be further rotated relative to the rear leg frame 20, which can be understood as gradually flattening the backrest frame 70 so that the push handle frame 80 contacts the ground or other supporting platform, thereby supporting the backrest frame 70. At the same time, the footrest frame 50 also flips upward and gradually flattens, and then the footrest support frame 60 is unfolded and abuts against the ground or other supporting platform. In this way, the folding chair frame 100 can be fully unfolded, with supporting structures at both the front and rear, thereby further improving the stability of the folding chair when used as a chair.

[0058] Combination Figure 1 and Figure 2 It should be noted that the 50mm footrest is... Figure 1 In the state shown, it is possible to further follow Figure 2 The direction shown is opposite to direction C. Relating to the rear leg 20, the footrest 50 rotates to a state approximately perpendicular to the rear leg 20. At this point, the footrest 50 and the backrest 70 can also be understood as being roughly parallel. Thus, a storage space can be formed between the footrest 50, the rear leg 20, and the backrest 70, facilitating the placement of items by the user and realizing the storage function of the folding chair, thereby enhancing its multi-functionality.

[0059] Furthermore, in order to improve the stability of the push handle frame 80 and to lock and fix the push handle frame 80 and the backrest frame 70 when it is rotated to a certain angle, in this embodiment, the folding chair frame 100 also includes a locking member 93, which is disposed at the connection between the push handle frame 80 and the backrest frame 70.

[0060] It should be noted that the structure of the locking member 93 is not limited, as long as it can achieve the locking and fixing of the push handle frame 80 and the backrest frame 70. For example, in this embodiment, the locking member 93 includes a button, a rotating shaft, and a spring. The button is connected to the rotating shaft, and the rotating shaft is provided with multiple limiting protrusions. The spring is sleeved on the rotating shaft. The push handle frame 80 is provided with multiple limiting grooves that cooperate with the limiting protrusions.

[0061] In other words, when no external force is applied to the button, the limiting protrusion on the rotating shaft is engaged in the limiting groove under the elastic force of the spring, thereby locking the push handle 80 and the backrest frame 70. When the button is pressed, the limiting protrusion on the rotating shaft will separate from the limiting groove, at which point the push handle 80 can be rotated.

[0062] Combination Figure 2Understandably, when folding is required, the user can press the button on the locking part 93 to separate the limiting protrusion on the pivot from the limiting groove, at which point the push handle 80 and the backrest 70 are unlocked; then the push handle 80 is operated to rotate relative to the backrest 70 in the D direction, which can also be understood as rotating clockwise. After the overall folding is completed, the button is released to lock and fix the push handle 80 and the backrest 70 after folding.

[0063] Please continue to combine Figure 1 Specifically, the push handle frame 80 includes a first push handle tube 81, a second push handle tube 82, and a third connecting tube 83. The first push handle tube 81 and the second push handle tube 82 are respectively connected to both ends of the third connecting tube 83. The end of the first push handle tube 81 away from the third connecting tube 83 is hinged to the first backrest tube 71, and the end of the second push handle tube 82 away from the third connecting tube 83 is hinged to the second backrest tube 72.

[0064] It should be noted that in this embodiment, there are two locking members 93. One locking member 93 is disposed at the hinge between the first push handle tube 81 and the first backrest tube 71, and the other locking member 93 is disposed at the hinge between the second push handle tube 82 and the second backrest tube 72. Of course, in other embodiments, there may be only one locking member 93, which may be disposed at the hinge between the first push handle tube 81 and the first backrest tube 71, or at the hinge between the second push handle tube 82 and the second backrest tube 72.

[0065] In summary, the embodiments of this utility model provide a folding chair frame 100 and a folding chair. The folding chair frame 100 includes a front leg 10, a rear leg 20, a support tube 30, and a flipping member 40. The rear leg 20 is hinged to the front leg 10. The two ends of the support tube 30 are respectively hinged to the rear leg 20 and the flipping member 40. The flipping member 40 is hinged to the front leg 10. The flipping member 40 is used to rotate relative to the front leg 10 under the action of external force, so as to drive the rear leg 20 to rotate relative to the front leg 10 through the support tube 30. As is easily understood, during use, the flipping component 40 is flipped. As the flipping component 40 rotates relative to the front leg 10 or the rear leg 20, the support tube 30 also moves accordingly. This, in turn, drives the rear leg 20 to rotate relative to the front leg 10, achieving the overall unfolding and folding of the folding chair frame 100. The operation is convenient and quick, the unfolding and folding process is smooth, and compared to existing methods using sliding components, the surface of the leg tubes is less prone to damage, improving the user experience. Furthermore, after the folding chair frame 100 is unfolded, the support tube 30 also supports the front leg 10 and the rear leg 20, improving stability during use.

[0066] The folding chair includes a folding chair frame 100, which has all the functions and benefits of the folding chair frame 100.

[0067] The above description is merely a specific embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
