Description

A gravity-based self-locking foldable suspended platform device and a folding method for the suspended platform. Technical Field

[0001] This invention relates to a folding basket, and more particularly to a gravity-based self-locking folding basket that can switch between a folded and unfolded state under the action of an external force. Specifically, during the folding and unfolding process, the basket's own weight can provide a driving force to keep the basket folded and unfolded, thereby reducing the effort required by the user in folding and unfolding operations. Background Technology

[0002] Folding hanging baskets are a popular type of leisure furniture, combining portability and comfort, providing users with an ideal option for relaxing and enjoying outdoor time.

[0003] First, folding baskets are typically designed with portability and ease of storage in mind. Some baskets feature a foldable structure, allowing them to be easily folded up when not in use, saving space and making them convenient to carry and store.

[0004] A foldable hanging basket and chair (CN219629163U) includes a fixed frame, a hinged base, a left frame assembly, and a right frame assembly. The hinged base includes two semi-circular plates that are arranged parallel to each other and fixedly connected. The two adjacent frames of the left and right frame assemblies can be fixedly connected by a connecting structure. In the unfolded state, all frames cannot rotate due to the connecting structure. When not in use, each frame of the left and right frame assemblies rotates to the left and right sides respectively to fold up the hanging basket.

[0005] A foldable suspended basket (CN216602194U) effectively connects and stabilizes the right and left main ribs through the action of two arc-shaped pads, thus improving the stability of the assembled suspended basket. By disassembling the first and second screws with a wrench, the right and left main ribs are pushed towards the secondary ribs, causing the suspended basket to fold together.

[0006] A folding hanging chair (CN210249191U) includes two end connecting plates and several intermediate arc-shaped curved rods, two outer arc-shaped curved rods and two outer frame arc-shaped curved rods. The two ends of the intermediate arc-shaped curved rods are rotatably connected to the two end connecting plates respectively. The second connecting pieces at both ends of the outer frame arc-shaped curved rods are rotatably connected to the outer edges of the end connecting plates respectively. The intermediate arc-shaped curved rods, outer arc-shaped curved rods and outer frame arc-shaped curved rods are connected adjacent to each other by a flexible material. The two ends of the two outer frame arc-shaped curved rods are respectively provided with plug-in structures. When the two outer frame arc-shaped curved rods are unfolded around the end connecting plates, their ends are joined together and fixed by fasteners.

[0007] The aforementioned folding basket requires screws to lock it in the unfolded state to keep it in that state; when it needs to be folded, the screws are removed to facilitate folding. Switching between the two states of the basket requires screws and tools to tighten them, which is inconvenient. In addition, there is also the problem of losing the screws after they are removed.

[0008] Summary of the Invention

[0009] To address the inconvenience caused by the need to use or remove screws during the unfolding and folding of the aforementioned foldable suspended baskets, this invention provides a foldable suspended basket that utilizes its own weight to maintain it in both folded and unfolded states.

[0010] The core technical concept of this invention is to utilize the principle of gravity self-locking and control the critical position of the traction branch and shaft connection to achieve automatic folding and unfolding of the suspended basket, simplifying the operation process and improving the convenience and safety of use.

[0011] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a gravity-locking foldable hanging basket device, including a bracket, a hanging device and a hanging basket forming a sitting and lying space, wherein the upper end of the hanging basket is hung on the upper end of the bracket by the hanging device;

[0012] The suspended platform is composed of two symmetrical suspended platform components, and a flexible connector is provided between adjacent suspended platform components;

[0013] The suspended basket assembly includes a frame composed of multiple poles and flexible connectors connecting adjacent poles.

[0014] The frame includes a front main frame and at least two support rods. The two front main frame rods form the entrance ring of the basket, and all the support rods form the back fence of the basket.

[0015] The front main frame includes an arc-shaped main body section and connecting sections located at the upper and lower ends of the arc-shaped main body section; the arc-shaped main body section is bent in the plane where the entrance annular ring is located, and the connecting sections bend and extend from the arc-shaped main body section in the direction of the sitting and reclining space; the upper and lower ends of the support rod are respectively axially connected to the upper and lower connecting sections of the front main frame; the free ends of the connecting sections of the left and right front main frame are axially connected to each other to form an upper axial connection point and a lower axial connection point;

[0016] The lifting device includes three inverted Y-shaped traction branches on the same plane. The upper traction branch is fixedly connected to the upper end of the support; the lower ends of the two lower traction branches are respectively connected to the upper end of the arc-shaped main body section near the connecting section.

[0017] When the upper shaft contact is located in the plane where the three traction branches are located, it is the critical position for the deployment and folding of the basket. When the upper shaft contact moves in the first direction and crosses the critical position, the basket's own weight will assist in continuing to push the basket to complete the folding and retraction movement, and all the poles of the basket in the folded and retracted state will come together. When the upper shaft contact moves in the second direction and crosses the critical position, the basket's own weight will assist in continuing to push the basket to complete the deployment movement, and all the poles of the basket in the deployed state will be separated from each other at a preset distance. The separation distance of all the poles is limited by the length of the flexible connecting belt.

[0018] A further preferred embodiment of the present invention is: the two connecting segments on the left and right form an angle to form a trumpet-shaped structure, and the upper shaft contact and the lower shaft contact are located at the inner end of the trumpet-shaped structure;

[0019] Alternatively, the free ends of the two connecting sections on the left and right can be joined together so that the arc-shaped main body sections of the two front main frame rods on the left and right can be connected in a continuous manner.

[0020] A further preferred embodiment of the present invention is that the flexible connector is a woven rope, rattan, or cloth strip.

[0021] A further preferred embodiment of the present invention is as follows: the three traction branches are three metal chain branches or high-strength ropes; the upper end of the bracket is connected to a spring, and the upper traction branch is connected to the spring.

[0022] A further preferred embodiment of the present invention is that the front main frame rod and the support rod are one or more of iron pipe, aluminum pipe or stainless steel pipe.

[0023] Another preferred subject: a hanging basket device, comprising a support frame, a sling and a hanging basket forming a sitting or reclining space, the upper end of the hanging basket being suspended from the upper end of the support frame by the sling;

[0024] The suspended platform includes two front main frame rods and a back assembly that can be folded or unfolded with a limited span, connected between the two front main frame rods.

[0025] The two front main frame rods are arc-shaped rods, and their upper and lower ends are connected to form upper and lower shaft joints, which together form an entrance ring for users to sit in.

[0026] The lifting device includes three inverted Y-shaped traction branches on the same plane. The upper traction branch is fixedly connected to the upper end of the bracket, and the lower ends of the two lower traction branches are connected to the corresponding front main frame near the upper shaft joint. The two lower traction branches are symmetrically arranged so that the basket is in a hanging state.

[0027] When the upper shaft contact is located in the plane where the three traction branches are located, it is the critical position for the deployment and folding of the basket. When the upper shaft contact moves in the first direction and crosses the critical position, the two front main frames automatically retract relative to each other based on the weight of the basket, and drive the back assembly to fold. When the upper shaft contact moves in the second direction and crosses the critical position, the two front main frames automatically unfold outward based on the weight of the basket, and drive the back assembly to unfold.

[0028] A further preferred embodiment of the present invention is as follows: the front main frame includes an arc-shaped main body segment and connecting segments located at the upper and lower ends of the arc-shaped main body segment, wherein the connecting segments bend and extend from the arc-shaped main body segment toward the direction of the suspended basket space;

[0029] The back assembly includes multiple spaced rods, which are evenly axially connected to the corresponding front main frame. Flexible connectors are provided between adjacent rods, and the front main frame rods are also connected to adjacent rods via flexible connectors.

[0030] A further preferred embodiment of the present invention is that the flexible connector is one or more of a woven rope, rattan, or cloth strip;

[0031] The three traction branches are either three metal chain branches or one or two types of high-strength ropes;

[0032] The upper end of the bracket is connected to a spring, and the upper traction branch is connected to the spring;

[0033] The front main frame rod and support rod are one or more of iron pipe, aluminum pipe or stainless steel pipe.

[0034] Another preferred subject: a hoisting device comprising a support frame, a hoisting device, and a basket forming a sitting or reclining space, the upper end of the basket being suspended from the upper end of the support frame by the hoisting device;

[0035] The suspended platform includes two front main frame rods and at least two support rods. The front main frame rods form the entrance annular ring of the suspended platform, and the support rods form the back railing of the suspended platform. A flexible connector is provided between the two front main frame rods.

[0036] The front main frame includes an arc-shaped main body section and a connecting section, with an included angle between the arc-shaped main body section and the connecting section;

[0037] The upper and lower ends of the support rod are respectively axially connected to the upper and lower connecting sections of the front main frame rod;

[0038] The lifting device includes three traction branches in an inverted Y shape, wherein the upper traction branch is connected to the upper end of the support, and the lower ends of the two lower traction branches are respectively connected to the upper end of the arc-shaped main body section near the connecting section;

[0039] When the upper shaft connection is located in the plane where the three traction branches are located, it is the critical position for the basket to unfold and fold.

[0040] Once the upper shaft connection point crosses the critical position, the basket automatically completes the folding process based on its own weight and the force exerted on the front main frame by the lower connection point of the lifting device.

[0041] When the upper shaft connection moves backward and passes the critical position, the basket automatically completes the deployment process based on its own weight and the force exerted on the front main frame by the lower connection point of the lifting device.

[0042] A further preferred embodiment of the present invention is that the flexible connector is one or more of the following: woven rope, rattan, and cloth strips;

[0043] The three traction branches are either three metal chain branches or one or two types of high-strength ropes;

[0044] The upper end of the bracket is connected to a spring, and the upper traction branch is connected to the spring;

[0045] The front main frame rod and support rod are one or more of iron pipe, aluminum pipe or stainless steel pipe.

[0046] Another preferred subject of the present invention: a folding method for the suspended basket device, the specific steps of which are as follows:

[0047] When in use, the suspended platform is in the unfolded state. The user applies a force to the two front main frame rods of the suspended platform to move them toward the support rods. The two front main frame rods rotate synchronously along the upper shaft joint and the lower shaft joint.

[0048] When the front main frame rotates backward, the upper shaft joint moves forward to the plane position where the three chain branches are located, which is the critical position for the basket to unfold and fold. After the upper shaft joint passes the critical position, the basket's own weight will help push the basket to complete the folding and retraction movement, and all the poles of the basket in the folded and retracted state will come together.

[0049] Another preferred subject of the invention: a method for deploying a suspended basket device.

[0050] The hoisting basket is in a folded state, and a force is applied to the two front main frame rods to move away from the support rods. The two front main frame rods rotate synchronously along the upper shaft joint and the lower shaft joint.

[0051] When the front main frame rotates forward, the upper shaft joint moves backward to the plane position where the three chain branches are located, which is the critical position for the basket to unfold and fold. When the upper shaft joint moves backward and passes the critical position, the basket's own weight will help to continue to push the basket to complete the unfolding movement. All the poles of the basket in the unfolded state are separated from each other at a preset distance. The separation distance of all the poles is limited by the length of the flexible connecting belt.

[0052] The advantages of this invention are: by utilizing the principle of gravity self-locking, the basket can automatically lock during the unfolding and folding process without the need for additional locking devices or operations, only the application of external force is required, which greatly simplifies the operation process and improves safety.

[0053] Moreover, the structure of the suspended platform is relatively simple, consisting of a small number of main components, making it easy to manufacture and maintain, thus reducing manufacturing and maintenance costs.

[0054] Meanwhile, the basket structure exhibits strong stability, especially when a user sits inside. The gravity-locking effect is further enhanced by the user's weight, eliminating the risk of accidental operation inherent in traditional self-locking structures. In other words, the gravity-locking mechanism in this invention provides a stable locked state, reducing the risk of accidental folding or unfolding due to locking mechanism failure.

[0055] In addition, thanks to the gravity self-locking mechanism, the basket can complete the conversion from folding to unfolding or from unfolding to folding in a very short time.

[0056] Furthermore, in the folded state, all the poles of the suspended platform can be compactly brought together, effectively saving storage and transportation space and improving space utilization. Moreover, the overall volume of this suspended platform in the folded state is smaller than that of conventional suspended platforms, and even smaller than that of a disassembled suspended platform. The smaller folded volume can significantly reduce the storage and transportation pressure on enterprises.

[0057] In terms of stability and comfort, the use of flexible connectors in the frame provides good stability and comfort during use.

[0058] Furthermore, regarding the folding method of this hanging basket, users can easily unfold and fold it with simple physical actions (pushing or pulling), without the need for complex mechanical operations or tool assistance. Utilizing the basket's own gravity as an auxiliary force reduces the effort required by the user during operation, making the entire process much easier. Moreover, this method allows the basket to quickly transition from a usable state to a stored state, improving its utilization efficiency. Attached Figure Description

[0073] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of the invention.

[0074] In the description of this invention, it should be noted that the terms "upper," "lower," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Similarly, terms such as "first" and "second" are only for the purpose of facilitating understanding and have no other directional meaning, and should not be regarded as limitations on this invention.

[0075] As shown in Figures 1 to 4, the gravity-locking foldable hanging basket device 100 includes a support 101, a lifting device 102, and a hanging basket 103 forming a sitting / lying space p. The upper end of the hanging basket 103 is hung on the upper end of the support 101 via the lifting device 102.

[0076] The support frame is the supporting structure of the 101 suspended platform device and is usually placed on the ground; it provides vertical support for the suspended platform and ensures its stability during use. The lifting device 102 allows the suspended platform 103 to be suspended from the support frame 101, allowing the suspended platform 103 to swing or sway appropriately in space, increasing the comfort of use.

[0077] The hanging basket 103 is the main part of the device, providing a sitting or reclining space p for the user to rest or relax. The sitting or reclining space p is ergonomically designed to provide comfortable support.

[0078] The hanging basket 103 consists of two symmetrically arranged sub-basin assemblies 10, with flexible connectors s connecting adjacent basket assemblies 10. Each sub-basin assembly 10 includes a frame 11 composed of multiple poles and flexible connectors s connecting adjacent poles. The flexible connectors s ensure synchronous linkage between the two sub-basin assemblies 10, allowing for coordinated movement of each part when the basket is unfolded or folded. The flexible connectors s help control the extent of the poles' unfolding or folding. Furthermore, because the flexible connectors s allow for a certain degree of elastic deformation, they can absorb and disperse vibrations caused by user activity, improving comfort when sitting or lying down.

[0079] Furthermore, the flexible connectors allow the individual poles of the basket to fold smoothly, reducing friction and resistance during the folding process. Due to their flexible nature, the connectors reduce potential collisions and damage between rigid components during folding and unfolding, and also result in a smaller overall volume after folding.

[0080] The frame 11 includes a front main frame rod a1 and at least two support rods a2. The two front main frame rods a1 form the entrance ring 13 of the hanging basket, and the opening of the entrance ring 13 is large enough for the user to freely enter and exit the sitting and lying space. All the support rods a2 form the back railing 14 of the hanging basket to support the back area of ​​the human body and provide the user with stable and comfortable sitting and lying conditions.

[0081] It should be noted that, of course, a flexible fabric surface can also be connected only between the two front main frame rods a1, with the aim of achieving the purpose of self-locking of the suspended basket based on its own weight. The specific technical solution of the back component can be flexibly changed, for example, a purely flexible fabric surface can be used.

[0082] The front main frame a1 includes an arc-shaped main body section a11 and connecting sections a12 located at the upper and lower ends of the arc-shaped main body section a11. The arc-shaped main body section a11 is bent in the plane where the entrance annular ring 13 is located, and the connecting section a12 bends and extends from the arc-shaped main body section a11 in the direction of the sitting / lying space p.

[0083] The curved main body section a11 is the main part of the front main frame a1. It bends on the plane where the entrance annular ring 13 is located, forming the front profile of the suspended basket. The curved design not only provides an aesthetically pleasing appearance but also offers users a better view and a more comfortable experience during use. The degree of curvature and dimensions of the curved main body section a11 ensure the stability and durability of the suspended basket.

[0084] Connecting sections a12 are located at the upper and lower ends of the curved main body section a11. They bend and extend from the curved main body section a11 towards the direction of the reclining space p and connect to the support rod a2. Connecting sections a12 have sufficient strength and toughness to withstand various forces generated by the user when using the suspended platform.

[0085] The upper and lower ends of the support rod a2 are respectively axially connected to the upper and lower connecting sections of the front main frame rod a1; the free ends of the connecting sections a12 of the left and right front main frame rods a1 are axially connected to each other, forming the upper axial connection point g1 and the lower axial connection point g2.

[0086] The upper and lower ends of the support rod a2 are respectively pivotally connected to the upper and lower connecting sections of the front main frame rod a1, providing a stable frame structure for the suspended platform. The rotation of the support rod a2, combined with the upper and lower pivot points of the front main frame rod a1, allows for more efficient use of applied external force, making the folding and unfolding process smoother and less strenuous. Users can control the folding and unfolding of the suspended platform by simple actions (such as pushing or pulling) to rotate the support rod a2 and the front main frame rod a1, without the need for complex operations or tools.

[0087] In addition, the synchronous rotation of the support rod a2 and the front main frame rod a1 ensures the consistency and uniformity of the suspended platform when changing states, avoiding structural damage or imbalance caused by asynchronous movement of some components.

[0088] Regarding the upper and lower shaft joints, during the folding process of the suspended platform, the user applies a force to the front main frame rod a1 towards the support rod a2. The front main frame rod a1 rotates synchronously along the upper shaft joint g1 and the lower shaft joint g2, thereby realizing the folding of the suspended platform.

[0089] During the deployment of the suspended platform, the user applies an outward force to the front main frame rod a1, causing it to rotate synchronously along the upper shaft joint g1 and the lower shaft joint g2, thus deploying the suspended platform. More specific technical methods will be described below:

[0090] As shown in Figures 5 to 7, the lifting device 102 includes three inverted Y-shaped traction branches 30 on the same plane. The upper traction branch 31 is fixedly connected to the upper end of the support 101; the lower ends of the two lower traction branches 32 are respectively connected to the upper ends of the arc-shaped main body section a11 near the connecting section a12. Of course, the lower ends of the two lower traction branches 32 can also be connected to the connecting section a12, or to the upper part of the arc-shaped main body section a11 away from the connecting section a12. These connection points can all allow the basket to be flexibly unfolded or folded.

[0091] When the upper shaft contact g1 is located in the plane position where the three traction branches 30 are located, it is the critical position for the basket to unfold and fold.

[0092] The upper traction branch 31 is fixedly connected to the upper end of the bracket 101, while the two lower traction branches 32 are connected to the upper end of the arc-shaped main body section a11 of the front main frame rod a1 (or the lower ends of the two lower traction branches 32 can also be connected to the connecting section a12, or connected to the upper part of the arc-shaped main body section a11 away from the connecting section a12), which can form a stable triangular structure and enhance the stability of the suspended basket.

[0093] Users can control the relative position of the upper shaft contact g1 and the plane of the traction branch 30 to unfold or fold the suspended platform, simplifying the operation process. Moreover, the position of the upper shaft contact g1 corresponds to the plane of the traction branch 30, so that the suspended platform has a clear reference point at the critical position of unfolding and folding, which is convenient for users to identify and operate.

[0094] More importantly, when the upper shaft contact g1 crosses the critical position, the basket's own weight will assist in pushing the basket to complete the folding or unfolding action, using gravity as the driving force to achieve a self-locking function. This provides a more effortless and convenient user experience.

[0095] As shown in Figures 10 and 11, when the upper shaft contact g1 moves in the first direction and passes the critical position, the weight of the basket will assist in continuing to push the basket 103 to complete the folding and retracting movement, and all the poles of the basket in the folded and retracted state will come together; as shown in Figures 8 and 9, when the upper shaft contact g2 moves in the second direction and passes the critical position, the weight of the basket 103 will assist in continuing to push the basket 103 to complete the unfolding movement, and all the poles of the basket in the unfolded state will be separated from each other at a preset distance; the separation distance of all the poles is limited by the length of the flexible connecting belt.

[0096] The movement of the upper shaft contact g1 and the lower shaft contact g2 triggers the automatic folding and unfolding of the basket, using its own weight as the driving force, thus reducing the complexity of user operation. In the folded state, all the poles are brought together, minimizing the space occupied by the basket and alleviating storage and transportation pressure.

[0097] The flexible connecting strip limits the maximum distance the rods can separate, preventing the front main frame rod a1 from expanding beyond its limit.

[0098] More importantly, the suspended platform automatically reaches its final folded or unfolded state based on its own weight, reducing reliance on external forces. Moreover, since unfolding and folding can be completed based on its own weight, complex mechanical parts are reduced, making the overall structure of the suspended platform simpler and saving production costs.

[0099] The aforementioned technical solution emphasizes that the suspended platform utilizes its own weight as a driving force to achieve automatic folding and unfolding, reducing the complexity of manual operation. When a user sits in the platform, their weight increases the gravitational force acting on it, thereby enhancing the self-locking effect and making the platform more stable under load, reducing the risk of accidents. Furthermore, the user's weight naturally participates based on the product's usage characteristics, making the entire locking and securing action more natural and eliminating the need for additional complex locking operations for safe use.

[0100] This technological innovation, utilizing gravity as a driving force, showcases the product's advanced design concepts and technological breakthroughs in the leisure furniture field. By cleverly transforming gravity into ease of operation, this hanging basket device not only enhances the user experience but also strengthens the product's practicality and safety by simplifying the operation process. Furthermore, this technological approach reflects a strong focus on environmental protection and economy, providing new directions for the design and manufacturing of leisure furniture.

[0101] Preferably, the left and right connecting segments a12 are in a trumpet shape, with the upper shaft joint g1 and the lower shaft joint g2 located at the inner ends of the trumpet shape. The trumpet shape provides a larger support area, thereby enhancing the structural strength of the connecting segment a12. The trumpet shape also helps to distribute the force transmitted by the support rod a2 more evenly, reducing stress concentration; it also allows for smoother folding and unfolding movements, improving the folding efficiency of the basket. Furthermore, this technique helps the upper and lower shaft joints maintain better balance and stability during the unfolding and folding of the basket.

[0102] Alternatively, as shown in Figures 12 and 13, a shaft-connecting plate is provided at the connection between the connecting section a12 of the front main frame rod a1 and the arc-shaped main body section a11, and the support rod a2 is shaft-connected to the corresponding shaft-connecting plate. In the retracted state, as shown in Figure 12, the free end of the connecting section a12 of the front main frame rod a1 is shaft-connected, and the left and right connecting sections a12 are roughly on the same straight line; in the unfolded state, as shown in Figure 13, the left and right connecting sections a12 are rotated and retracted based on their free ends, so that the front sections of the left and right arc-shaped main body sections a11 are connected and the outer edge of the entire suspended basket frame forms a continuous ring structure, making it more comfortable for users to sit in, and the appearance is more coherent and beautiful.

[0103] Furthermore, preferably, the flexible connector s is a woven rope, rattan, or cloth strip. Materials such as woven rope, rattan, and cloth strips offer a variety of weaving methods and styles, providing diverse options for the design of the hanging basket.

[0104] The three traction branches 30 are three branches of metal chains or high-strength ropes; the metal chains or high-strength ropes provide extremely high strength and durability, capable of withstanding various forces generated during the use of the suspended platform. These materials allow the traction branches 30 to have a certain degree of flexibility, enabling the suspended platform to swing appropriately during use.

[0105] In addition, it should be noted that the length of the lower traction branch 32 is directly related to the connection point at the lower end of the lower traction branch 32. Specifically, the further away the connection point at the lower end of the two lower traction branches 32 is from the connection segment a12, the longer the length of the lower traction branch 32 should be.

[0106] A spring 40 is connected to the upper end of the bracket 101, and the upper traction branch 31 is connected to the spring 40. The spring 40 absorbs the vibration generated by using the suspended platform, reducing the impact on the platform structure and the user. The spring 40 can automatically adjust its tension to adapt to different weight loads, ensuring the balance and stability of the suspended platform.

[0107] In summary, the combination of the three high-strength traction branches 30 and the spring 40 provides additional safety and ensures the stability of the suspended platform during use.

[0108] The following describes the unfolding and folding methods of the hoisting equipment. The specific steps for folding the suspended platform equipment are as follows:

[0109] 1.1 When in use, the suspended platform is in the unfolded state. The user applies a force to the two front main frame rods of the suspended platform 103, which moves towards the support rod a2. The two front main frame rods a1 rotate synchronously along the upper shaft joint g1 and the lower shaft joint g2.

[0110] 1.2 When the front main frame rod a1 rotates backward, the upper shaft contact g1 moves forward to the plane position where the three chain branches 30 are located, which is the critical position for the unfolding and folding of the basket 103; when the upper shaft contact g1 passes the critical position, the weight of the basket 103 will assist in pushing the basket to complete the folding and retraction movement, and all the rods a2 of the basket 103 in the folded and retracted state will come together.

[0111] Method for deploying the suspended platform:

[0112] 1.1 When the hoisting basket 103 is in a folded state, a force is applied to the two front main frame rods a1 to move away from the support rods. The two front main frame rods a1 rotate synchronously along the upper shaft joint g1 and the lower shaft joint g2.

[0113] 1.2 When the front main frame rod a1 rotates forward, the upper shaft contact g1 moves backward to the plane position where the three chain branches are located, which is the critical position for the unfolding and folding of the basket 103. When the upper shaft contact g1 moves backward and passes the critical position, the self-weight of the basket 103 will continue to push the basket 103 to complete the unfolding movement. All the rods a2 of the basket in the unfolded state are separated from each other at a preset distance. The separation distance of all the rods a2 is limited by the length of the flexible connecting belt s.

[0114] The folding method of this hanging basket allows users to easily unfold and fold it with simple physical actions (pushing or pulling), without the need for complex mechanical operations or tools. Utilizing the basket's own weight as an auxiliary force reduces the effort required by the user during operation, making the entire process much easier. Furthermore, this method allows the basket to quickly transition from a usable state to a stored state, improving its utilization efficiency.

[0115] In summary, the technical advantage of this invention is that by utilizing the principle of gravity self-locking, the suspended basket 103 can automatically lock during the unfolding and folding process without the need for additional locking devices or operations; only external force needs to be applied, which greatly simplifies the operation process and improves safety.

[0116] Moreover, the structure of the suspended platform 103 is relatively simple, consisting of a small number of main components, making it easy to manufacture and maintain, thus reducing manufacturing and maintenance costs. Furthermore, the modular design of the sub-suspended platform components 10 allows for a degree of modularity, meaning that in the event of damage or the need for replacement, only the damaged portion can be replaced, rather than the entire suspended platform.

[0117] Meanwhile, the basket structure exhibits strong stability, especially when a user sits inside. The gravity-locking effect is further enhanced by the user's weight, eliminating the risk of accidental operation inherent in traditional self-locking structures. In other words, the gravity-locking mechanism in this invention provides a stable locked state, reducing the risk of accidental folding or unfolding due to locking mechanism failure.

[0118] Furthermore, thanks to the gravity self-locking mechanism, the basket 103 can complete the conversion from folding to unfolding or from unfolding to folding in a very short time.

[0119] Furthermore, in the folded and stowed state, all the poles a2 of the basket 103 can be tightly packed together, effectively saving storage and transportation space and improving space utilization.

[0120] In terms of stability and comfort, the use of flexible connectors s on the frame 11 provides good stability and comfort during use of the suspended platform 103.
