Description

Technical Field

[0001] The utility model relates to the technical field of outdoor products, in particular to a folding chair. Background Art

[0002] Traditional folding chairs are still bulky even when folded, making them inconvenient to carry for extended periods or use in limited space. Furthermore, due to structural design limitations, the folding and unfolding process can be complex and inconvenient. Some traditional folding chairs require multiple fasteners or connectors during assembly, increasing assembly complexity and time costs. Furthermore, due to inadequately tight or secure connections between components, they can easily become loose or damaged after a period of use. Summary of the Invention

[0003] The problem solved by the utility model is how to overcome the obvious defects in the assembly of the folding chair to meet the user's demand for easy folding, convenient unfolding and closing.

[0004] In order to solve the above problems, the utility model provides a folding chair, comprising a base frame and a detachable support seat mounted on the base frame;

[0005] The chassis comprises a plurality of brackets positioned adjacent to each other and continuously, each bracket having a pair of hinged support rods;

[0006] Each of the support rods has a lower end and an upper end, wherein the lower ends of adjacent support rods and the upper ends of adjacent support rods in adjacent brackets are connected to each other via elastically deformable sleeves;

[0007] The two opposite groups of brackets are respectively provided with limiting belts, and the two ends of the limiting belts are respectively detachably connected to the two support rods of the brackets.

[0008] With the above structure, the detachable support base is mounted on the base frame, and the base frame is composed of multiple sets of hinged support rods, which are interconnected by elastically deformable sleeves. This allows the entire folding chair to be easily folded into a smaller size when not in use, making it easy to carry and store. This is particularly important for outdoor activities, travel, or living environments with limited space. The design of connecting the lower and upper ends of adjacent support rods through elastically deformable sleeves not only ensures flexibility during folding, but also ensures a tight connection between the various components when in use, that is, when the chair is unfolded, thereby improving the overall stability of the chair. The provision of limiting straps further enhances the structural stability of the chair in the unfolded state and prevents unnecessary shaking or deformation of the support rods during use. The provision of limiting straps not only enhances the stability of the chair but also improves its safety to a certain extent. They can prevent the support rods from suddenly unfolding or folding in unexpected circumstances, reducing the risk of injury due to improper operation.

[0009] Furthermore, the base frame is composed of four groups of brackets, including:

[0010] A front bracket, a rear bracket and two side brackets, the support rods of the front bracket have the same first preset length, the support rods of the rear bracket have the same second preset length, the first preset length is smaller than the second preset length, and each of the side brackets has a support rod with the same first preset length and the same second preset length.

[0011] Furthermore, the plurality of elastically deformable sleeves form four corners at the upper ends of two adjacent support rods, and each corner forms a gusset plate that enables the support seat to be suspended.

[0012] Furthermore, a plurality of the elastically deformable sleeves form a base with four legs at the lower ends of two adjacent support rods.

[0013] Furthermore, the limiting belt includes a first limiting belt and a second limiting belt, and the first end fixed heights of the first limiting belt and the second limiting belt are respectively greater than the second end fixed heights of the first limiting belt and the second limiting belt.

[0014] Furthermore, both ends of the limiting belt are respectively arranged close to the upper end of the support rod.

[0015] The utility model adopts the above technical solution to achieve the following beneficial effects:

[0016] This utility model utilizes a detachable support base mounted on a base frame, which is composed of multiple sets of hinged support rods interconnected by elastically deformable sleeves. This allows the entire folding chair to be easily folded into a compact size when not in use, making it easy to carry and store. This is particularly important for outdoor activities, travel, or living environments with limited space. The elastically deformable sleeves connect the lower and upper ends of adjacent support rods. This design not only ensures flexibility during folding but also ensures a tight connection between the components when in use, i.e., when the chair is unfolded, thereby enhancing the chair's overall stability. The provision of stoppers further enhances the chair's structural stability in the unfolded state, preventing the support rods from undesirably shaking or deforming during use. The stoppers not only enhance the chair's stability but also improve safety. They prevent the support rods from unexpectedly expanding or collapsing, reducing the risk of injury from improper operation. This overcomes significant assembly drawbacks of folding chairs, meeting user demands for easy folding, convenient opening and closing, and improving the user experience.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments. Example

[0024] This embodiment provides a folding chair, such as Figure 1 and Figure 3 As shown, it includes: a base frame and a detachable support base 4 mounted on the base frame;

[0025] The chassis comprises a plurality of brackets positioned adjacent to each other and continuously, each bracket having a pair of hinged support rods 1;

[0026] Each support rod 1 has a lower end and an upper end, wherein the lower ends of adjacent support rods in adjacent brackets and the upper ends of adjacent support rods are connected to each other through elastically deformable sleeves 2 respectively;

[0027] The two opposing groups of brackets are respectively provided with limiting belts 3 , and both ends of the limiting belts 3 are detachably connected to the two support rods 1 of the brackets.

[0028] Specifically, the chair's folding and portability are achieved through a base frame composed of multiple sets of adjacent, continuously positioned brackets. Each bracket consists of a pair of hinged support rods 1, and elastically deformable sleeves 2 connect the lower and upper ends of adjacent support rods 1. This allows the chair to be easily folded into a smaller size when not in use, making it easy to carry and store, solving the problem of traditional chairs taking up a lot of space and being inconvenient to carry.

[0029] Specifically, regarding stability and support: gussets formed by elastically deformable sleeves 2 at the four corners of the base frame provide stable suspension points for the support base 4. This structure not only enhances the chair's overall stability but also ensures the safety and comfort of the support base when bearing weight. Furthermore, the provision of limiting straps 3 further limits deformation of the support when deployed, enhancing the chair's stability.

[0030] Specifically, structural flexibility: The base frame is composed of four sets of brackets of different lengths, including a front bracket, a rear bracket, and two side brackets. The front and rear brackets have rods of different lengths, while the side brackets each contain rods of the same length as the front and rear brackets. This design allows the chair to maintain structural stability while maintaining a certain degree of flexibility, allowing it to be adjusted to different usage needs or user preferences.

[0031] Specifically, it is easy to assemble and disassemble: all components, including the bracket, elastically deformable sleeve 2, limiting belt 3 and support base 4, are connected in a detachable manner, making the assembly and disassembly of the chair simple and quick. Users can easily assemble or disassemble it as needed, making it easy to clean and maintain.

[0032] Specifically, the base frame is constructed from multiple sets of adjacent, continuously positioned brackets. The hinged design of each bracket's support rod (1) ensures the chair maintains structural stability both when folded and unfolded. Furthermore, the use of elastically deformable sleeves (2) imparts flexibility to the connections between adjacent support rods (1), providing both necessary support during use and a smooth transition when folded, enhancing the chair's flexibility and portability.

[0033] Specifically, the support seat 4 is detachably mounted on the base frame, and combined with the design that the two ends of the limiting belt 3 are detachably connected to the support rod 1, the entire chair is very convenient and quick to assemble and disassemble, without the need for complicated tools or professional skills, and is suitable for a variety of occasions and users' quick layout needs.

[0034] The chassis consists of four sets of brackets, including:

[0035] A front bracket, a rear bracket and two side brackets, the support rods 1 of the front bracket have the same first preset length, the support rods 1 of the rear bracket have the same second preset length, the first preset length is smaller than the second preset length, and each side bracket has a support rod 1 with the same first preset length and second preset length.

[0036] The plurality of elastically deformable sleeves 2 form four corners at the upper ends of two adjacent support rods 1 , and each corner forms a gusset plate for suspending the support base 4 .

[0037] Among them, a plurality of elastically deformable sleeves 2 form a base with four legs at the lower ends of two adjacent support rods 1.

[0038] Specifically, the base frame consists of four sets of brackets. The support rods (1) of the front, rear, and side brackets are designed with different lengths, ensuring a stable support structure when the chair is unfolded while maintaining a visually appealing aesthetic. Furthermore, the gussets formed by the elastically deformable sleeves (2) at the upper ends of the support rods (1) provide a stable suspension point for the support base (4), while the base formed at the lower ends enhances the chair's stability.

[0039] See Figure 2 , wherein the limiting belt 3 includes a first limiting belt 301 and a second limiting belt 302, and the first end fixed heights of the first limiting belt 301 and the second limiting belt 302 are respectively greater than the second end fixed heights of the first limiting belt 301 and the second limiting belt 302.

[0040] Specifically, the design of the limiting straps 3, particularly the different heights of the first and second limiting straps 301 and 302, provides a sense of restraint when the user sits down, preventing safety hazards caused by chair sway while also helping to maintain a comfortable sitting posture. Furthermore, the cushioning effect of the elastically deformable sleeve 2 can also mitigate the impact of sitting down, enhancing the user experience.

[0041] The two ends of the limiting belt are respectively arranged close to the upper end of the support rod.

[0042] This structure utilizes a removable support base mounted on a base frame, which is composed of multiple sets of hinged rods interconnected by elastically deformable sleeves. This allows the folding chair to be easily folded into a compact size when not in use, making it easy to carry and store. This is particularly important for outdoor activities, travel, or living environments with limited space. The elastically deformable sleeves connect the lower and upper ends of adjacent rods. This design not only ensures flexibility during folding but also ensures a tight connection between the components when in use (i.e., when the chair is unfolded), thereby enhancing the chair's overall stability. The provision of stoppers further enhances the chair's structural stability in the unfolded state, preventing the rods from swaying or deforming during use. The stoppers not only enhance the chair's stability but also improve safety. They prevent the rods from unexpectedly expanding or collapsing, reducing the risk of injury from improper operation. This overcomes significant assembly drawbacks of folding chairs, meeting user demands for easy folding, convenient opening and closing, and improving the user experience.

Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the scope of protection of the utility model.
