Description

Technical Field

[0001] This application relates to the technical field of tourism products, and in particular to a folding chair. Background Technology

[0002] Folding chairs are a common type of furniture and are widely used in various settings such as homes, offices, and outdoor activities.

[0003] The existing Chinese invention patent with publication number CN116421015B discloses a folding chair that is easy to store, including a foldable chair frame and a support component set on the chair frame for supporting the human body. The chair frame includes a seat frame, a backrest frame and a front support frame rotatably connected to the seat frame via connectors, a rear support frame rotatably connected to the front support frame, two armrests rotatably connected to the backrest frame, and two support components set on the seat frame respectively. The upper connecting end of the support component is connected to the armrest, and the lower connecting end of the support component is connected to the rear support frame. The support component is provided with a reinforcing component to enhance the support.

[0004] However, the aforementioned technologies have the following problems: Since the backrest frame and the front support frame are rotatably connected to the seat frame via connectors, in order to ensure that there is no interference during rotation, a certain amount of space needs to be reserved on the seat frame for rotation. This results in the space that could originally be used for the seat being occupied, thereby shortening the seat depth. Consequently, when users use folding chairs, insufficient seat depth will cause the body to not be adequately supported, especially the thighs, which cannot be fully placed on the seat. Prolonged use can easily lead to fatigue, reducing user comfort and satisfaction. Utility Model Content

[0005] In order to overcome the aforementioned technical problems, this application provides a folding chair.

[0006] The folding chair provided in this application adopts the following technical solution: A folding chair includes a seat, a front leg frame connected to the seat, a rear leg frame hinged to the front leg frame, a support assembly mounted on the seat, a backrest connected to the support assembly, and two armrests respectively hinged to the backrest. The armrests are connected to the rear leg frame via a sliding structure. The upper connecting part of the support assembly is connected to the backrest, and the lower supporting part of the support assembly is connected to the rear leg frame. The lower supporting part and the upper connecting part of the support assembly are offset to increase the seat depth.

[0007] By adopting the above technical solution, the armrests and rear support leg frame are connected by a sliding structure, which realizes the adjustable tilt angle of the chair back and meets the needs of different users; the lower support part and the upper connecting part of the support component are staggered front and rear, which shifts the center of gravity of the folding chair to the rear, increases the seat depth, and improves the user experience.

[0008] Preferably, the support assembly includes a support bar and a first connecting piece. The support bar is hinged to the rear support leg frame. One end of the support bar away from the rear support leg frame is slidably connected to a sliding hole in the first connecting piece. The first connecting piece is fixedly connected to the seat, and the first connecting piece is provided with an upper connecting lug for hinged connection to the backrest.

[0009] By adopting the above technical solution, the support bar is hinged to the rear support leg frame and slides in the sliding hole of the first connecting piece. The first connecting piece is fixed to the seat and is provided with an upper connecting ear for hinged backrest, which enables the backrest to be hinged more smoothly and makes the support more stable when the folding chair is unfolded. At the same time, the support bar and the upper connecting ear are misaligned, which shifts the center of gravity of the folding chair to the rear, increases the seat depth, and improves the user experience.

[0010] Preferably, the support assembly includes a telescopic rod and a second connecting piece. The outer rod of the telescopic rod is hinged to the rear support leg frame, and the inner rod of the telescopic rod is hinged to the second connecting piece. The second connecting piece is fixed to the seat, and the second connecting piece is provided with an upper lug for hinged connection to the backrest.

[0011] By adopting the above technical solution, the lower support part of the support component uses a telescopic rod, which is staggered with the upper connecting part to shift the center of gravity of the folding chair backward, increase the seat depth, and improve the user experience. The telescopic rod has a simple structure, is easy to manufacture and maintain, and its extension and retraction movements are smoother during the unfolding and storage of the folding chair, thus improving the convenience of use.

[0012] Preferably, an auxiliary support is provided between the seat and the rear leg frame, and the supporting part of the auxiliary support abuts against the rear leg frame.

[0013] By adopting the above technical solution, when the folding chair is unfolded, the support part of the auxiliary support component abuts against the rear support leg frame and cooperates with the support component to form double support, thereby enhancing the stability of the folding chair after it is unfolded.

[0014] Preferably, the auxiliary support includes a hinge plate and an abutment block. The two ends of the hinge plate are respectively hinged to the seat and the rear support leg frame. The abutment block is connected to the end of the hinge plate away from the rear support leg frame and abuts against the side arm of the rear support leg frame.

[0015] By adopting the above technical solution, the two ends of the hinge plate of the auxiliary support are respectively hinged to the seat and the rear support frame, and the abutment block is connected to the end of the hinge plate away from the rear support frame. The abutment block abuts against the side arm of the rear support frame, which enhances the stability of the folding chair after unfolding, improves the shortcomings of the existing folding chair, and improves the practicality and comfort of the folding chair.

[0016] Preferably, a reinforcing member is provided between the two side arms of the front outrigger frame. The reinforcing member includes two fixing strips respectively provided on the two side arms of the front outrigger frame and a reinforcing rod connecting the two fixing strips.

[0017] By adopting the above technical solution, the reinforcement components enhance the structural stability of the front support leg frame, making the overall structure of the folding chair more compact.

[0018] Preferably, the bottom end of the fixing strip extends into an extension portion, which is fixedly connected to the ground support portion of the front support leg frame.

[0019] By adopting the above technical solution, the bottom end of the fixing strip extends out to be fixedly connected to the ground support part of the front outrigger frame, which can form a triangular support at the bend of the front outrigger frame and enhance the structural stability of the front outrigger frame.

[0020] Preferably, the chair seat is provided with a rotatable support rod.

[0021] By adopting the above technical solution, the support rod can be used as a handle when folding the chair, making it easy to carry the folded chair. The support rod can also rotate relative to the chair frame, making it convenient to use in different states.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The armrests and rear support leg frame are connected by a sliding structure, which enables the backrest tilt angle to be adjusted to meet the needs of different users; the lower support part and the upper connecting part of the support component are staggered front and rear, which shifts the center of gravity of the folding chair to the rear, increases the seat depth, and improves the user experience. 2. The support bar is hinged to the rear support leg frame and slides in the sliding hole of the first connecting piece. The first connecting piece is fixed to the seat and has an upper connecting ear for hinged backrest, which enables the backrest to be hinged more smoothly and makes the support more stable when the folding chair is unfolded. At the same time, the support bar and the upper connecting ear are staggered front and back, which shifts the center of gravity of the folding chair to the rear, increases the seat depth, and improves the user experience. 3. When the folding chair is unfolded, the support part of the auxiliary support component abuts against the rear support leg frame, and works with the support component to form double support, which enhances the stability of the folding chair after it is unfolded.

[0032] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0033] This application discloses a folding chair, which mainly adopts a scheme with an adjustable backrest tilt angle and increased seat depth, thereby improving the stability of the folding chair and the user experience. The following is a further detailed description of this application.

[0034] Example 1 Reference Figure 1 and Figure 2The folding chair includes a seat, a front support leg frame 1 connected to the seat, a rear support leg frame 2 hinged to the front support leg frame 1, a support assembly mounted on the seat, a backrest connected to the support assembly, and two armrests 3 respectively hinged to the backrest. The armrests 3 are connected to the rear support leg frame 2 via a sliding structure, allowing the backrest tilt angle to be adjusted. The upper connecting part of the support assembly is connected to the backrest to connect the backrest and the seat; the lower supporting part of the support assembly is connected to the rear support leg frame 2 to provide stable support for the unfolded folding chair; and the lower supporting part and the upper connecting part of the support assembly are offset front to back, allowing the center of gravity of the unfolded folding chair to shift backward, thereby increasing the seat depth and improving the user experience.

[0035] The chair seat includes a chair seat frame 4 and a chair seat body 41 disposed on the chair seat frame 4. The chair seat body 41 is the seat surface of the folding chair. The chair back includes a chair back frame 5 and a chair back body 51 disposed on the chair back frame 5. The chair back body 51 is used to support the user's back. In this embodiment, the chair seat frame 4, chair back frame 5, front support leg frame 1, and rear support leg frame 2 are all frames with a U-shaped cross-section.

[0036] When the folding chair is unfolded, the seat frame 4 is horizontally positioned with its opening facing the seated side of the chair. The opening of the front leg frame 1 is angled upwards, and the seat frame 4 is located inside the front leg frame 1. The outer side of the side arm of the seat frame 4 is hinged to the inner side of the corresponding side arm of the front leg frame 1. The opening of the rear leg frame 2 is also angled upwards, and the inclination directions of the front leg frame 1 and the rear leg frame 2 are opposite. Both side arms of the rear leg frame 2 are equipped with hinge seats 21, and the ends of the side arms of the front leg frame 1 are hinged to the rear leg frame 2 via the hinge seats 21. When the folding chair is unfolded, the front leg frame 1 and the rear leg frame 2 support the ground.

[0037] When the folding chair is unfolded, the opening of the backrest frame 5 faces the seat frame 4, and the backrest frame 5 is located between the two armrests 3. The ends of the two armrests 3 that are close to each other are hinged to the outer sides of the two side arms of the backrest frame 5. The armrests 3 have ergonomic curved curves. When the user rests their arms on the armrests 3, the curved curves can effectively relieve arm pressure and increase the user's arm comfort, thereby improving the user experience.

[0038] Reference Figure 2 and Figure 3The number of sliding structures is consistent with the number of armrests 3 and corresponds one-to-one. The sliding structure includes an adjustment seat 6 fixedly connected to the bottom surface of the armrest 3 and a snap-fit ​​component 61 set on the side arm of the rear support frame 2 and slidably snap-fitted with the adjustment seat 6. The cross-section of the adjustment seat 6 is U-shaped and its opening faces away from the armrest 3. Both sides of the adjustment seat 6 are provided with elongated holes 62, and the length direction of the elongated holes 62 is consistent with the length direction of the adjustment seat 6. Multiple oblique snap-fit ​​holes 63 are also provided on the side of the adjustment seat 6, which are spaced apart along the length direction of the elongated holes 62. The multiple oblique snap-fit ​​holes 63 are all connected to the side of the elongated holes 62 near the armrest 3. The oblique snap-fit ​​holes 63 are inclined upwards away from the backrest frame 5. The side arm end of the rear outrigger frame 2 extends through the opening of the adjusting seat 6 to the space between the two sides of the adjusting seat 6. The snap-fit ​​part 61 is connected to the side arm end of the rear outrigger frame 2, and the snap-fit ​​part 61 is slidably connected to the elongated hole 62. The two ends of the snap-fit ​​part 61 are two snap-fit ​​parts of the snap-fit ​​part 61. The snap-fit ​​parts of the snap-fit ​​part 61 extend through the elongated hole 62 to the outside of the adjusting seat 6, and the snap-fit ​​parts of the snap-fit ​​part 61 are snapped into the oblique snap-fit ​​hole 63.

[0039] Therefore, when it is necessary to increase the tilt angle of the backrest frame 5, lift the armrest 3 away from the backrest frame 5, and the locking piece 61 slides from the angled locking hole 63 to the elongated hole 62. Then push the armrest 3 towards the backrest frame 5. At this time, while the locking piece 61 slides in the elongated hole 62, the armrest 3 pushes the backrest frame 5 to increase the tilt angle of the backrest frame 5. Then release the armrest 3. Under the action of the armrest 3's own weight, the locking part of the locking piece 61 engages in the corresponding angled locking hole 63, thus completing the fixation of the adjusted backrest frame 5.

[0040] Reference Figure 2 and Figure 4 The support components are provided in two sets, which are respectively connected to the two side arms of the seat frame 4. The upper connecting part of the support component is hinged to the end of the side arm of the backrest frame 5. The lower supporting part of the support component is connected to the side arm of the rear leg frame 2, so that the lower supporting part of the support component is supported between the seat frame 4 and the rear leg frame 2, so as to achieve stable support for the unfolded folding chair.

[0041] The support assembly includes a support bar 7 and a first connecting piece 71. The support bar 7 is slidably connected to the first connecting piece 71. The first connecting piece 71 is fixedly connected to the side arm of the seat frame 4 and is adjacent to the backrest frame 5. The top surface of the first connecting piece 71 is formed with an upper connecting ear 711 extending to the top of the seat frame 4. The upper connecting ear 711 is the upper connecting part of the support assembly and is hinged to the end of the side arm of the backrest frame 5. The support bar 7 is the lower support part of the support assembly. The bottom surface of the first connecting piece 71 is formed with a lower connecting ear 712 extending to the bottom of the seat frame 4. The lower connecting ear 712 is offset from the upper connecting ear 711. A sliding hole 713 is provided on the side of the lower connecting ear 712, which is arc-shaped. The outer end of the support bar 7 is hinged to the inner side of the side arm of the rear support leg frame 2. A sliding part 72 is provided at the end of the support bar 7 away from the rear support leg frame 2. The sliding part 72 is slidably connected to the sliding hole 713.

[0042] Preferably, two first connecting pieces 71 are provided on the same set of support components, and the support bar 7 is located between the two first connecting pieces 71, so that the backrest frame 5 can be more smoothly hinged between the two upper connecting ears 711, while the support bar 7 can slide more smoothly between the two lower connecting ears 712. When the folding chair is unfolded, the sliding part 72 engages with the end of the sliding hole 713, so that the support bar 7 is supported between the rear support leg frame 2 and the seat frame 4.

[0043] To create a double support and make the unfolded folding chair more stable, an auxiliary support is provided between the rear leg frame 2 and the seat frame 4. When the folding chair is unfolded, the sliding part 72 engages with the end of the sliding hole 713 to form the first layer of support, while the supporting part of the auxiliary support abuts against the side arm of the rear leg frame 2 to form the second layer of support.

[0044] Two sets of auxiliary support components are provided, each connected to one of the two side arms of the rear support leg frame 2. Each auxiliary support component includes an abutment block 8 and hinge pieces 81, with their opposite ends hinged to the side arms of the seat frame 4 and the rear support leg frame 2, respectively. The abutment block 8 is connected to the end of the hinge piece 81 furthest from the rear support leg frame 2. The abutment block 8 serves as the supporting part of the auxiliary support component; when the folding chair is unfolded, the abutment block 8 abuts against the side arm of the rear support leg frame 2 to provide support. Preferably, the abutment block 8 is cylindrical, and two hinge pieces 81 are provided on the same set of auxiliary support components, with both the side arm of the rear support leg frame 2 and the abutment block 8 located between the two hinge pieces 81.

[0045] To enhance the structural stability of the front outrigger frame 1 and the rear outrigger frame 2, reinforcing strips 11 are fixedly connected to the two bends of the front outrigger frame 1 and the two bends of the rear outrigger frame 2. The reinforcing strips 11 can form triangular supports at the bends of the front outrigger frame 1 and the rear outrigger frame 2, thereby enhancing the structural stability of the front outrigger frame 1 and the rear outrigger frame 2.

[0046] Reference Figure 2 and Figure 5 To enhance the structural stability of the seat frame 4 and facilitate the carrying of the folded chair, a support rod 42 is provided at the opening of the seat frame 4 and between the two side arms of the seat frame 4. When the folding chair is folded, the support rod 42 can be used as a handle, thus making it easier to carry the folded chair.

[0047] The bottom of each of the two side arms of the chair frame 4 is provided with mounting components, and the support rod 42 is mounted at the opening of the chair frame 4 through the mounting components. The mounting components include a mounting plate 43 and a mounting member 44. The mounting plate 43 is fixed to the bottom of the side arm of the chair frame 4, and the middle part of the mounting plate 43 is bent outward to form a clearance opening. The rod body of the mounting member 44 passes through the clearance opening and is fixedly connected to the end of the support rod 42. The connection between the mounting member 44 and the support rod 42 is located at the axis of the end of the support rod 42. The clearance opening limits the head of the mounting member 44, thereby allowing the support rod 42 to rotate relative to the chair frame 4. In this embodiment, the mounting member 44 includes, but is not limited to, rivets, pins, and bolts.

[0048] The implementation principle of Embodiment 1 of this application is as follows: the sliding connection between the armrest 3 and the rear support frame 2 enables the adjustable tilt angle of the chair back, meeting the needs of different users; the staggered arrangement of the lower support part and the upper connecting part of the support component shifts the center of gravity of the folding chair backward, increases the seat depth, and improves the user experience; the setting of the auxiliary support enhances the stability of the folding chair after unfolding; these designs improve the shortcomings of existing folding chairs and enhance the practicality and comfort of the folding chair.

[0049] Example 2 Reference Figure 6 and Figure 7The difference between this embodiment and Embodiment 1 lies in the supporting components. In this embodiment, the supporting components include a telescopic rod 9 and a second connecting piece 91. The second connecting piece 91 is fixedly connected to the side arm of the seat frame 4 and is adjacent to the backrest frame 5. The top surface of the second connecting piece 91 has an upper ear 911 extending above the seat frame 4. The upper ear 911 is the upper connecting part of the supporting components, and the upper connecting ear 711 is hinged to the end of the side arm of the backrest frame 5. The telescopic rod 9 is the lower supporting part of the supporting components. The bottom surface of the second connecting piece 91 has a lower ear 912 extending below the seat frame 4. The telescopic rod 9 consists of an inner rod and an outer rod that are nested together. The outer rod of the telescopic rod 9 is hinged to the inner side of the side arm of the rear support leg frame 2, and the inner rod of the telescopic rod 9 is hinged to the lower ear 912.

[0050] Preferably, two second connecting pieces 91 are provided on the same set of support components. The side arm ends of the backrest frame 5 are located between the two upper ears 911, so that the backrest frame 5 can be more smoothly hinged between the two upper ears 911, while the inner rod of the telescopic rod 9 can be more smoothly hinged between the two lower ears 912. When the folding chair is fully unfolded, the telescopic rod 9 can no longer retract. At this time, the end of the inner rod extending into the outer rod abuts against the inner end wall of the outer rod, so that the telescopic rod 9 is supported between the rear support leg frame 2 and the seat frame 4.

[0051] The implementation principle of Embodiment 2 of this application is as follows: the telescopic rod 9 is used as the lower support part of the support component, which can also achieve the front-to-back misalignment of the lower support part and the upper connecting part of the support component, so that the center of gravity of the folding chair is shifted backward and the seat depth is increased; the structure of the telescopic rod 9 is relatively simple, easy to manufacture and maintain, and the telescopic rod 9 moves more smoothly during the unfolding and storage of the folding chair, which improves the ease of use of the folding chair.

[0052] Example 3 Reference Figure 8 The difference between this embodiment and Embodiment 1 is that a reinforcing member is provided between the two side arms of the front outrigger frame 1. In this embodiment, the reinforcing member includes two fixing strips 12 respectively disposed on the two side arms of the front outrigger frame 1 and a reinforcing rod 13 disposed between the two fixing strips 12; the reinforcing rod 13 provides corresponding support.

[0053] In this embodiment, the inner side of the side arm of the front support leg frame 1 is movably riveted to the outer side of the side arm of the seat frame 4, and the top end of the fixing strip 12 is movably riveted between the inner side of the side arm of the front support leg frame 1 and the outer side of the side arm of the seat frame 4. The connection points of the front support leg frame 1, the seat frame 4 and the fixing strip 12 are located at the same place. The bottom end of the fixing strip 12 is fixedly riveted to the inner side of the side arm of the front support leg frame 1, and the end of the reinforcing rod 13 is fixedly riveted to the middle of the fixing strip 12. Thus, the presence of the fixing strip 12 and the reinforcing rod 13 makes the unfolded folding chair subject to dual forces in both the longitudinal and transverse directions.

[0054] Preferably, an extension (not shown in the figure) can be formed at the bottom end of the fixing strip 12, and the end of the extension away from the fixing strip 12 is fixed to the ground support part of the front support leg frame 1, so that the extension can form a triangular support at the bend of the front support leg frame 1, thereby enhancing the structural stability of the front support leg frame 1.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
