[0032] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0033] The present invention provides a rocking chair frame and a rocking chair, which can solve the problems described in the background art, enabling the rocking chair itself to provide rocking assistance and improve the user experience. The following is a detailed description of the present invention.

[0034] Please refer to Figures 1 to 4 The rocking chair frame includes a support assembly 1, a rotating seat tube assembly 2, and an elastic element 4. The support assembly 1 includes a support tube 10, a horizontal tube 11, and a fixed seat tube 12. The horizontal tube 11 is connected to the support tube 10, and the fixed seat tube 12 is rotatably connected to the support tube 10. The rotating seat tube assembly 2 is rotatably connected to the fixed seat tube 12 through a rotating connecting seat 3. The two ends of the elastic element 4 are respectively connected to the rotating seat tube assembly 2 and the horizontal tube 11.

[0035] In this embodiment of the utility model, the rocking chair frame rotatably connects the rotating seat tube assembly 2 to the fixed seat tube 12. When a person sits on the rotating seat tube assembly 2, the rotating seat tube assembly 2 can rotate to realize the rocking function, while the support assembly 1 with the fixed seat tube 12 does not move. The elastic element 4 is stretched or compressed during the rotation of the rotating seat tube assembly 2. When the elastic element 4 is stretched or compressed, it stores elastic potential energy, thereby providing rocking assistance to the rotating seat tube assembly 2. The required external force is reduced, the rocking is more continuous and more comfortable, which is conducive to improving the user experience.

[0036] Specifically, the support component 1 includes a support tube 10, a horizontal tube 11, a fixed seat tube 12, a handrail 13, a transition tube 14, a buckle 15, and a locking seat 16.

[0037] In this embodiment, there are two support tubes 10, both of which are U-shaped. The two ends of each support tube 10 are rotatably connected to the armrest 13 via pins. The bottoms of both support tubes 10 can contact the ground for support, and anti-slip components are provided at the bottom of each support tube 10 to prevent slipping during use. The bottom end of the support tube 10 closer to the front of the armrest 13 slopes forward towards the rocking chair, while the bottom end of the support tube 10 closer to the rear of the armrest 13 slopes backward towards the rear of the rocking chair, thus forming a figure-eight shape for stable support. In other embodiments, there can be four support tubes 10, with two of the four support tubes intersecting and their top ends connected to the armrest 13.

[0038] One end of the locking seat 16 is connected to the support tube 10 near the rear of the armrest 13 and can rotate around the connection point. The locking seat 16 and the support tube 10 are connected by a pin. The other end of the locking seat 16 is inserted with a pin, through which a latch 15 and an adapter tube 14 also pass. The latch 15 is a U-shaped plate. One end of the adapter tube 14 is housed inside the U-shaped plate, and the other end of the adapter tube 14 is rotatably connected to the armrest 13 via a connecting pin. The bottom wall of the U-shaped plate can connect with the fixed seat tube 12, thus stabilizing and fixing the seat tube 12. The locking seat 16 has a locking groove that matches the support tube 10. The support tube 10 can be inserted into the locking groove and locked, thereby fixing the position of the adapter tube 14. The adapter tube 14 pulls the latch 15 to move, causing the bottom wall of the latch 15 to lock into the fixed seat tube 12. At this time, the support assembly 1 of the rocking chair frame is fully extended.

[0039] The fixed seat tube 12 can be a U-shaped tube, with its two sides connected to the support tube 10 near the front of the handrail 13. The fixed seat tube 12 and the connected support tube 10 can rotate, and the fixed seat tube 12 and the support tube 10 near the rear of the handrail 13 are not directly connected.

[0040] The horizontal tube 11 is connected to the support tube 10 near the front of the armrest 13. The horizontal tube 11 cannot move relative to the support tube 10; that is, the horizontal tube 11 and the support tube 10 are fixedly connected. They can be connected by screws or welding. In the rocking chair frame in the unfolded state, the horizontal tube 11 is lower than the fixed seat tube 12, meaning the horizontal tube 11 is positioned lower than the fixed seat tube 12. This facilitates the placement of the elastic element 4, through which the rotating seat tube assembly 2 is connected.

[0041] In this embodiment, the two ends of the U-shaped fixed seat tube 12 are fixedly connected to the middle support tube 17, which is located in the middle of the rocking chair frame. The middle support tube 17 can be connected to the rotating seat tube assembly 2.

[0042] Continue to refer to Figure 1 and Figure 2 The rotating seat post assembly 2 includes multiple horizontal rotating seat posts 20 and multiple vertical rotating seat posts 21. In this embodiment, there are two horizontal rotating seat posts 20 and two vertical rotating seat posts 21. The two vertical rotating seat posts 21 are parallel and spaced apart. The two ends of the two horizontal rotating seat posts 20 are respectively connected to the two vertical rotating seat posts 21, that is, the two horizontal rotating seat posts 20 are located between the two vertical rotating seat posts 21. Optionally, one end of the vertical rotating seat post 21 near the front of the rocking chair frame is bent and tilted downwards. This design allows the vertical rotating seat post 21 to fit the user's legs during use, allowing the legs to hang naturally.

[0043] As a first example, the end of the central support tube 17 is fixed to the fixed seat tube 12. Two rotating connecting seats 3 are sleeved on the central support tube 17 and can rotate around the central support tube 17. Both rotating connecting seats 3 have engaging grooves. The middle parts of the two vertical rotating seat tubes 21 are engaged in the engaging grooves, and the rotating connecting seats 3 are connected to the vertical rotating seat tubes 21 by screws or bolts. When the rotating connecting seats 3 rotate around the central support tube 17, they can drive the vertical rotating seat tubes 21 and the horizontal rotating seat tubes 20 to rotate, thereby providing a rocking function for the user sitting on the rotating seat tube assembly 2.

[0044] To prevent the rotary connecting seat 3 from moving axially on the central support tube 17, a retaining ring can be provided on the central support tube 17 to limit the rotary connecting seat 3. Alternatively, a radially contracting groove can be provided on the central support tube 17, and the rotary connecting seat 3 can be arranged in the groove. This can effectively prevent the rotary connecting seat 3 from moving axially along the central support tube 17.

[0045] In addition, to improve the smoothness of the rotation of the rotating connector 3 around the central support tube 17, the smoothness of the contact surface between the two can be improved to reduce the rotational friction, or lubricating oil can be added to the contact surface between the two.

[0046] As a second example, the central support tube 17 can also be rotatably coupled with the fixed seat tube 12. The rotating seat tube assembly 2 is fixed to the rotating connecting seat 3, and the rotating connecting seat 3 is fixed to the central support tube 17. When the central support tube 17 rotates, it can drive the rotating seat tube assembly 2 to rotate. For example, bearings are provided at both ends of the central support tube 17. The inner ring of the bearing is sleeved and fixed on the central support tube 17, and the outer ring of the bearing is fixed on the fixed seat tube 12. The central support tube 17 can rotate relative to the fixed seat tube 12.

[0047] Of course, the relative rotational engagement between the rotating seat tube assembly 2 and the fixed seat tube 12 can also be achieved without the middle support tube 17. In this case, the rotating seat tube assembly 2 can still use two horizontal rotating seat tubes 20 and two vertical rotating seat tubes 21. The connection method of the two horizontal rotating seat tubes 20 and the two vertical rotating seat tubes 21 is the same as described above. The rotating connecting seat 3 is replaced with a pin. The pin passes through the vertical rotating seat tube 21 and the fixed seat tube 12, so that the vertical rotating seat tube 21 can rotate around the pin. At the same time, the pin also plays the role of bearing and transmitting force, transmitting the pressure above the rotating seat tube assembly 2 to the fixed seat tube 12, and then the fixed seat tube 12 transmits the pressure to the support tube 10.

[0048] Connecting buckles 40 are provided on the horizontal tube 11 and the transverse rotating seat tube 20 near the side of the horizontal tube 11. The connecting buckles 40 can be arc-shaped strips welded to the horizontal tube 11 / transverse rotating seat tube 20. The elastic element 4 can be a spring, with its two ends hooked onto the two connecting buckles 40 respectively. When the spring is compressed, it will stretch back to its original shape, thereby pushing the rotating seat tube assembly 2 to rotate backward. When the spring is stretched, it will contract and shorten to return to its original shape, thereby pulling the rotating seat tube assembly 2 to rotate forward.

[0049] To ensure the continuity of the swaying of the rotating seat tube assembly 2, the number of elastic elements 4 can be set to multiple, with the multiple elastic elements 4 distributed at intervals.

[0050] refer to Figure 1 and Figure 2 The vertical rotating seat tube 21 is also connected to the backrest tube assembly 5. The backrest tube assembly 5 can rotate synchronously with the vertical rotating seat tube 21. The backrest tube assembly 5 provides a backrest for the user. The bottom end of the backrest tube assembly 5 is located inside the U-shaped fixed seat tube 12, which limits the rotation range of the backrest tube assembly 5 and prevents the backrest tube assembly 5 from rotating excessively.

[0051] Optionally, the backrest tube assembly 5 includes two longitudinal uprights 50 and several transverse baffles 51. The two ends of the several transverse baffles 51 are respectively fixed to the two longitudinal uprights 50. The lower end of the longitudinal uprights 50 is connected to the limiting rotating seat. The limiting rotating seat is rotatably connected to the vertical rotating seat tube 21. The limiting rotating seat can rotate around the vertical rotating seat tube 21, and after rotating to a certain limit, the rear bottom end of the limiting rotating seat will abut against the vertical rotating seat tube 21.

[0052] In other embodiments, the backrest tube assembly 5 may also have other structural forms, which are not limited thereto.

[0053] refer to Figure 4 In this embodiment, after the rocking chair frame is folded up, the rotating seat tube assembly 2 and the support assembly 1 are roughly on the same plane, which can reduce the volume after folding up and help reduce space occupation.

[0054] Of course, to make it easier for users to rest their feet, footrest tubes can also be installed on the support tube 10, with both ends of the footrest tubes connected to the support tube 10 and located below the horizontal tube 11.

[0055] The rocking chair frame of this utility model has the advantages of stable structure and convenient unfolding and folding. At the same time, the elastic element 4 provides rocking assistance for the rotating seat tube assembly 2, resulting in a good user experience.

[0056] An embodiment of this utility model also provides a rocking chair, including a chair seat and the aforementioned rocking chair frame. The chair seat is mounted on a rotating seat tube assembly 2, allowing a person to sit and lean against it. The chair seat and the rotating seat tube assembly 2 can be connected by screws or adhesive, allowing the chair seat to rock together with the rotating seat tube assembly 2. The shape and size of the chair seat match the rotating seat tube assembly 2, ensuring that the chair seat does not affect the rotating and rocking function of the rotating seat tube assembly 2.

[0057] Alternatively, to facilitate the arrangement of the seat plate, the transverse rotating seat tube 20 can be configured to be curved, thereby allowing the arrangement of a seat plate with a concave seat surface so that the user will not slide when sitting.

[0058] In addition, a backrest panel can be installed on the backrest tube assembly 5 to improve the comfort of sitting. In this embodiment, the backrest panel can be an arc-shaped panel that is adapted to the arc-shaped transverse baffle 51. The arc-shaped panel is attached to the transverse baffle 51 by screws or glue.

[0059] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
