Description

Technical Field

[0001] This application relates to the field of furniture technology, and more particularly to a hanging structure and a hanging chair. Background Technology

[0002] A hanging chair is a piece of furniture suspended from a metal rod, ceiling, or tree branch. It is often made of natural materials such as rattan and bamboo, making it both environmentally friendly and durable. Indoors, it can serve as a reading nook, rest area, or chat room, creating a relaxed and pleasant atmosphere. Outdoors, it becomes an ideal leisure choice in patios, terraces, or gardens, allowing people to enjoy tranquility and comfort in nature.

[0003] However, existing hanging chair ropes have significant shortcomings, with the lack of an adjustable mechanism being particularly prominent. Because the ropes lack adjustment, when the hanging chair tilts back at an excessive angle, the angle cannot be effectively limited, potentially causing the chair to tip over and posing a significant safety hazard, severely impacting the safety and stability of the hanging chair. Utility Model Content

[0004] The main purpose of this application is to provide a hanging structure and a hanging chair, which aims to solve the technical problem that existing hanging chairs cannot effectively limit the swing angle.

[0005] To achieve the above objectives, this application provides a suspension structure, the suspension structure comprising:

[0006] Lifting components;

[0007] A limiting component includes a fixed connector, a housing, an elastic snap-fit ​​component, and a limiting plate. The fixed connector is connected to the hoisting component. Two housings are provided, each fitted onto one side of the fixed connector. The inner wall of each housing has a series of continuous limiting slots along its circumference. The fixed connector has mounting slots that match the two housings. Each mounting slot contains an elastic snap-fit ​​component that matches the limiting slot. Each housing is connected to a limiting plate. By driving the limiting plates to move towards or away from each other, the included angle between the two limiting plates decreases or increases.

[0008] The sling is rotatably connected to the fixed connector.

[0009] Optionally, the elastic snap-fit ​​component includes a spring and a ball bearing, the spring being connected within the mounting groove, and the ball bearing being disposed between the spring and the limiting snap-fit ​​groove.

[0010] Optionally, the number of the elastic snap-fit ​​members is four, and the four elastic snap-fit ​​members are symmetrically arranged on both sides of the fixed connector.

[0011] Optionally, the hoisting component includes a hoisting rod and a hoisting member, the hoisting rod being connected to the top of the hoisting member, and the hoisting member being connected to the fixed connecting member.

[0012] Optionally, the top of the lifting member is provided with a mounting hole, a connecting nut is connected in the mounting hole, and the lifting rod has an external thread that is threaded to the connecting nut.

[0013] Optionally, the fixing connector is connected to the lifting member via a through-bolt.

[0014] Optionally, the sling is made of an alloy material.

[0015] To achieve the above objectives, this application also provides a hanging chair, including the hanging structure as described above, the hanging chair further including a seat and a pull rope, the hanging structure being connected to the seat via the pull rope.

[0016] Optionally, the hanging chair further includes a support structure, which includes a crossbar, a diagonal brace, and a support rod. The crossbar is vertically connected to the support rod, and the two ends of the diagonal brace are respectively connected to the crossbar and the support rod. The hoisting component is connected to the crossbar.

[0017] Optionally, the hanging chair further includes a rope assembly head, the number of pull ropes is several, one end of the rope assembly head is connected to the sling, the other end of the rope assembly head is connected to one end of several pull ropes, and the other end of several pull ropes is connected to the seat.

[0018] The beneficial effects that this application can achieve are:

[0019] The hanging structure proposed in this application, when the tilt angle of the hanging chair needs to be adjusted, drives the limiting plates to move in opposite directions or back to back, and simultaneously drives the outer shell to rotate. This causes the elastic locking member to be squeezed and retracted into the mounting groove. After the outer shell stops moving, the elastic locking member engages with the corresponding limiting slot under its own elasticity, thereby achieving the purpose of adjusting the angle between the two limiting plates to limit the rotation angle of the suspension rope. This effectively solves the problem that existing hanging chairs cannot effectively limit the swing angle due to the lack of an adjustable device for the suspension rope, and that the excessive tilt angle makes them prone to tipping over. This improves the safety and stability of the hanging chair. Attached Figure Description

[0028] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1 to 5 A suspension structure, the suspension structure includes

[0031] Lifting component 1;

[0032] The limiting component 2 includes a fixed connector 3, a housing 4, elastic snap-fit ​​components 5, and a limiting plate 6. The fixed connector 3 is connected to the hoisting component 1. There are two housings 4, each fitted onto one side of the fixed connector 3. The inner wall of the housing 4 has a series of continuous limiting slots 7 along its circumference. The fixed connector 3 has mounting slots 8 that match the two housings 4. Each mounting slot 8 has an elastic snap-fit ​​component 5 that matches the limiting slot 7. Each housing 4 is connected to a limiting plate 6. By driving the limiting plates 6 to move towards or away from each other, the included angle between the two limiting plates 6 decreases or increases.

[0033] Sling 9 is rotatably connected to fixed connector 3.

[0034] It should be noted that the continuous plurality of limiting slots 7 provided on the inner wall of the outer shell 4 in the circumferential direction means that the limiting slots 7 are continuously opened along the circumferential direction of the inner wall of the outer shell 4, the limiting slots 7 are adjacent to each other, and there is a connecting protrusion between each adjacent limiting slot 7.

[0035] In this embodiment, when the hanging structure is in operation, and the swing angle of the chair needs to be adjusted, the two limiting plates 6 are driven to move towards or away from each other, thereby causing the outer shells 4 fitted on both sides of the fixed connector 3 to rotate synchronously. During the rotation of the outer shell 4, the connecting protrusions between each adjacent limiting slot 7 will interact with the elastic locking parts 5 in the mounting groove 8 of the fixed connector 3: when the connecting protrusions between each limiting slot 7 rotate to the position of the elastic locking parts 5, the elastic locking parts 5 are compressed and undergo elastic deformation and retract into the mounting groove 8; when the outer shell 4 rotates to the target angle and stops, the elastic locking parts 5 pop out under their own elastic force and lock into the corresponding limiting slot 7. Through the locking and engagement of the elastic locking parts 5 and the limiting slots 7, the angle between the two limiting plates 6 is adjusted, thereby limiting the rotation angle of the sling 9 and achieving the purpose of controlling the swing angle of the chair.

[0036] In the above embodiment, when the tilt angle of the hanging chair needs to be adjusted, the limiting plate 6 is driven to move in opposite directions or in opposite directions, and the outer shell 4 is rotated simultaneously. This causes the elastic locking member 5 to be squeezed and retracted into the mounting groove 8. After the outer shell 4 stops moving, the elastic locking member 5 engages with the corresponding limiting groove 7 under its own elasticity, thereby adjusting the angle between the two limiting plates 6 to limit the rotation angle of the suspension rope 9. This effectively solves the problem that existing hanging chairs cannot effectively limit the swing angle due to the lack of an adjustable device for the suspension rope, and that the excessive tilt angle makes them prone to tipping over. This improves the safety and stability of the hanging chair.

[0037] As an feasible approach, refer to Figures 2 to 4The elastic snap-fit ​​component 5 includes a spring 10 and a ball 11. The spring 10 is connected in the mounting groove 8, and the ball 11 is disposed between the spring 10 and the limiting snap-fit ​​groove 7.

[0038] In this embodiment, when the elastic locking component 5 is composed of a spring 10 and a ball 11, its working principle is as follows: During the rotation of the outer shell 4 by the driving limiting plate 6, the adjacent connecting protrusions of the limiting groove 7 on the inner wall of the outer shell 4 will squeeze the ball 11. After being subjected to force, the ball 11 compresses the spring 10 in the mounting groove 8 and contracts into the groove. At this time, the spring 10 undergoes elastic deformation. When the outer shell 4 rotates to the target angle and the groove of the limiting groove 7 is aligned with the ball 11, the spring 10 pushes the ball 11 into the groove under the action of elastic force, forming a stable locking. During this process, the ball 11 can roll along the inner wall of the limiting groove 7, transforming the traditional sliding friction into rolling friction. The combination of spring 10 and ball bearing 11 enables dynamic engagement between elastic locking component 5 and limiting slot 7, which can precisely limit the rotation angle of sling 9 and solve the risk of tipping over caused by the lack of adjustment device for sling in existing hanging chairs. At the same time, the rolling friction of ball bearing 11 greatly reduces component wear, extends the service life of the structure, and makes the angle adjustment operation smoother, enhancing the convenience and safety of use.

[0039] As an feasible approach, refer to Figures 2 to 4 There are four elastic snap-fit ​​pieces 5, and the four elastic snap-fit ​​pieces 5 are symmetrically arranged on both sides of the fixed connector 3.

[0040] Understandably, the four elastic snap-fit ​​pieces 5 are symmetrically arranged on both sides of the fixed connector 3, meaning that the two outer shells 4 correspond to two symmetrically distributed elastic snap-fit ​​pieces 5.

[0041] In this embodiment, during the rotation of the outer shell 4 driven by the driving limiting plate 6, the symmetrically distributed elastic locking members 5 on both sides interact synchronously with the limiting grooves 7 on the inner wall of the outer shell 4. When the ball bearings 11 in each elastic locking member 5 are squeezed by the limiting grooves 7, the elastic deformation of the spring 10 realizes the contraction and ejection of the locking member. Since the four elastic locking members 5 are symmetrically distributed, the squeezing force on both sides of the fixed connector 3 is uniform when the outer shell 4 rotates, ensuring the smooth rotation of the outer shell 4. When the outer shell 4 rotates to the target angle, the four elastic locking members 5 simultaneously engage with the corresponding limiting grooves 7, forming a symmetrical locking structure. This allows the fixed connector 3 to be subjected to uniform force on both sides, avoiding structural displacement or jamming caused by excessive force on one side, and improving the stability of the suspension structure during rotation adjustment; the symmetrically distributed locking structure can provide a more balanced limiting force, accurately limiting the rotation angle of the sling 9, and effectively solving the problem of the existing hanging chair tipping over.

[0042] As an feasible approach, refer to Figure 1The hoisting component 1 includes a hoisting rod 12 and a hoisting member 13. The hoisting rod 12 is connected to the top of the hoisting member 13, and the hoisting member 13 is connected to the fixed connecting member 3.

[0043] In this embodiment, the top of the suspension rod 12 is used to connect to the ceiling, crossbar 19, and other supporting structures. The suspension rod 12 is connected to the top of the suspension member 13 to achieve the fixed installation of the lifting component 1. The bottom of the suspension member 13 is connected to the fixed connector 3, thereby transferring the load of the limiting component 2 and the sling 9 to the suspension rod 12. When the chair hanger is subjected to force and swaying, the tension of the sling 9 is transmitted to the suspension member 13 through the fixed connector 3, and then to the suspension rod 12 through the suspension member 13. Finally, the suspension rod 12 distributes the load to the supporting structure, achieving a reliable connection between the hanging structure and the supporting structure.

[0044] As an feasible approach, refer to Figure 1 and Figure 5 The top of the lifting component 13 has a mounting hole, and a connecting nut 14 is connected in the mounting hole. The lifting rod 12 has an external thread 15 that is threaded to the connecting nut 14.

[0045] In this embodiment, during installation, the external thread 15 of the suspension rod 12 is screwed into the connecting nut 14 inside the mounting hole of the hanger 13. The suspension rod 12 and hanger 13 are fixedly connected via the helical transmission of the threaded pair. This threaded connection allows adjustment of the vertical height of the hanger 13 by rotating the suspension rod 12 to accommodate different floor height requirements in various installation scenarios. When the chair is under load, the load is transmitted to the hanger 13 via the sling 9 and the fixed connector 3, and then to the suspension rod 12 via the meshing teeth of the connecting nut 14 and the external thread of the suspension rod 12. Finally, the suspension rod 12 distributes the force to the ceiling or supporting structure. The self-locking characteristic of the threaded connection prevents the hanger 13 from loosening due to vibration or other factors during use. By using a threaded connection, a detachable rigid connection is achieved between the suspension rod 12 and the suspension component 13. This ensures the overall strength of the suspension structure, effectively withstands the vertical load and lateral swaying force of the hanging chair, and solves the safety hazards caused by unreliable hoisting connections in existing hanging chairs. Furthermore, the installation height of the hanging chair can be precisely adjusted by rotating the suspension rod 12, improving the environmental adaptability of the device.

[0046] As an feasible approach, refer to Figure 2 and Figure 5 The fixed connector 3 is connected to the hanger 13 via the through bolt 16.

[0047] In this embodiment, the through-bolt 16 passes through the corresponding mounting holes of the fixed connector 3 and the hanger 13, and is locked by the nuts at both ends of the bolt, forming a rigid connection structure between the fixed connector 3 and the hanger 13. During installation, the mounting holes of the fixed connector 3 and the hanger 13 are aligned, the through-bolt 16 is inserted, and the nuts at both ends are tightened, using the axial tension of the bolt to fix the two together. When the chair swings under force, the load transmitted from the sling 9 to the fixed connector 3 is transmitted to the hanger 13 through the shear resistance of the through-bolt 16 and the locking force of the nuts, and then distributed from the hanger 13 to the support structure via the hanger rod 12. In this process, the through-bolt 16 ensures that the fixed connector 3 can maintain a stable axial position relative to the hanger 13, while allowing the housing 4 of the limiting component 2 to rotate around the fixed connector 3, realizing the angle adjustment function.

[0048] As a feasible approach, sling 9 is made of alloy material.

[0049] In this embodiment, the high strength of the alloy material significantly enhances the load-bearing capacity of the sling 9, allowing it to withstand greater weight compared to traditional fiber ropes. This avoids the risk of breakage caused by insufficient rope strength in existing hammocks. Furthermore, the rigidity of the alloy material reduces the elastic swaying amplitude during the hammock's swing, and, in conjunction with the limiting component 2, allows for more precise control of the swing angle, further improving the safety and reliability of the hammock.

[0050] To achieve the above objectives, this application also provides a hanging chair, including the hanging structure as described above. The hanging chair also includes a seat 17 and a pull rope 18, and the hanging structure is connected to the seat 17 via the pull rope 18.

[0051] As an feasible approach, refer to Figure 6 The hanging chair also includes a support structure, which includes a horizontal bar 19, a diagonal brace 20 and a support rod 21. The horizontal bar 19 is vertically connected to the support rod 21. The two ends of the diagonal brace 20 are connected to the horizontal bar 19 and the support rod 21 respectively. The hoisting component 1 is connected to the horizontal bar 19.

[0052] In this embodiment, the support rod 21 is vertically fixed to the ground or foundation structure, the crossbar 19 is vertically connected to the top of the support rod 21, and the two ends of the diagonal tie rod 20 are connected to the crossbar 19 and the middle of the support rod 21, respectively, forming a triangular stable support frame. The lifting rod 12 of the hoisting component 1 is connected to the crossbar 19, so that the load of the suspended structure is transferred to the support rod 21 and the diagonal tie rod 20 through the crossbar 19. In the triangular structure, the diagonal tie rod 20 can decompose the vertical load and lateral force on the crossbar 19 into axial pressure and tension, and use the geometric stability of the triangle to resist deformation. When the chair swings, the support structure, through the synergistic effect of the crossbar 19, the diagonal tie rod 20 and the support rod 21, distributes the load transferred by the suspended structure to the foundation structure, avoiding excessive stress at a single point.

[0053] As an feasible approach, refer to Figure 6 The hanging chair also includes a rope assembly head 22, and a number of pull ropes 18. One end of the rope assembly head 22 is connected to the sling 9, and the other end of the rope assembly head 22 is connected to one end of a number of pull ropes 18. The other end of the number of pull ropes 18 is connected to the seat 17.

[0054] In this embodiment, one end of the rope assembly head 22 is fixedly connected to the end of the sling 9, and the other end gathers several pull ropes 18. The other end of each pull rope 18 is connected to different suspension points of the seat 17, forming a multi-point suspension system. When the seat 17 bears the weight of a person, the load is transmitted to the rope assembly head 22 through each pull rope 18, and then from the assembly head to the sling 9. The load is then transmitted to the support structure through the fixed connector 3, the suspension member 13, and the suspension rod 12 of the suspension structure. When the chair swings, each pull rope 18 moves with the seat 17, causing the sling 9 to rotate. At this time, the rope assembly head 22 acts as the connection hub between the pull ropes 18 and the sling 9, which can evenly transmit the tension of multiple pull ropes 18 to the sling 9, avoiding uneven force on a single pull rope 18. The converging design of the assembly head ensures that the pull ropes 18 maintain synchronous extension and contraction during movement, ensuring the balance of the seat 17.

[0055] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
