Description

Technical Field

[0001] This utility model relates to the field of folding chair technology, and more specifically, to a folding rocking chair frame and a folding rocking chair. Background Technology

[0002] Existing outdoor folding chairs are widely used in various outdoor activities such as camping, fishing, and picnicking due to their ease of folding, storage, and portability. To improve user comfort, some folding chairs incorporate a rocking chair function into their traditional structure. The upper and lower supports can be tilted relative to each other, thus achieving a rocking effect. An elastic element is usually placed between the two supports to provide resistance and rebound force.

[0003] However, these portable rocking chairs are designed to be in a rocking state, lacking the ability to hold the seat firmly still. Users cannot freely switch between rocking chair mode and normal stationary chair mode according to their actual needs. This single function not only limits the usage scenarios of folding chairs, but also causes inconvenience when users need to maintain a stable sitting posture or use them on uneven ground, reducing the overall convenience and comfort of use. Summary of the Invention

[0004] While existing outdoor folding chairs are easy to store and carry, and can function as rocking chairs through the relative tilting of the upper and lower supports and the use of elastic components, they are always in a rocking state and lack the ability to fix the seat in a stable position, making it impossible to freely switch between rocking chair mode and ordinary stationary chair mode. This not only limits the usage scenarios of folding chairs, but also causes inconvenience when users need to maintain a stable sitting posture or when using them on uneven ground.

[0005] The purpose of this invention is to provide a folding rocking chair frame that can freely switch between rocking chair function and static state, thereby improving the convenience and comfort of existing portable rocking chairs and increasing the versatility of their applicable scenarios.

[0006] This utility model embodiment also proposes a folding rocking chair having the above-mentioned folding rocking chair frame.

[0007] The technical solution adopted by this utility model is: to provide a folding rocking chair frame, comprising:

[0008] The upper support assembly includes an upper top cover, an upper base, and multiple upper connecting rods. One end of each of the multiple upper connecting rods is connected to the upper top cover and can rotate relative to it. The upper top cover can swing back and forth relative to the upper base between a horizontal position and a downward swing position.

[0009] The lower support assembly includes a lower base and a plurality of lower connecting rods, one end of each lower connecting rod being connected to the lower base and rotatable relative to it, and the upper base being connected to the lower base;

[0010] A locking device is used to connect the upper top cover to the upper base in the locked state, so that the upper top cover is kept in a horizontal position to limit back-and-forth swinging, and in the unlocked state, the upper top cover is allowed to swing back and forth relative to the upper base.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects:

[0012] 1. Freely switch between modes to adapt to various usage scenarios.

[0013] The swinging state of the top cover can be controlled by a locking device installed between the top cover and the upper base. When the locking device is locked, the top cover is fixed in a horizontal position, restricting its back-and-forth swing, thus forming a stable static chair mode; when the locking device is unlocked, the top cover can swing freely back and forth relative to the upper base, realizing the rocking chair function.

[0014] This design enables the folding chair to switch freely between rocking chair mode and stationary chair mode, effectively solving the problem that existing portable rocking chairs are always in a rocking state and have a limited range of uses, allowing the product to be flexibly applied in various outdoor scenarios such as camping, picnics, and fishing.

[0015] 2. High stability in stationary mode, improving safety and comfort.

[0016] In the locked position, the entire seat structure is fixed in a stable state, preventing unnecessary swaying when the user needs to maintain a static posture. Furthermore, in environments with uneven ground or significant slopes, the locked position significantly improves the stability and load-bearing safety of the chair frame. This advantage provides users with a better comfort and safety experience during extended use, making it suitable for the elderly, children, or situations requiring focused attention.

[0017] 3. Maintain entertainment and leisure attributes in rocking chair mode.

[0018] In the unlocked state, the top cover can swing back and forth with the support of the upper base, forming a portable rocking chair for relaxation. Users can enjoy the comfort and relaxation brought by the rocking motion in camping, leisure, or outdoor environments, while retaining the original lightweight characteristics and quick unfolding and storage advantages of the folding chair.

[0019] 4. Simple structure, high reliability, easy to operate and carry.

[0020] The overall structure of this utility model consists of an upper support assembly, a lower support assembly, and a locking device. Combined with the rotatable design of the upper and lower connecting rods, it enables convenient folding and unfolding operations. The locking device allows for easy mode switching with a simple operation, enabling users to quickly transition between a stationary and rocking chair state. Furthermore, the chair's compact structure and lightweight design make it easy to carry and use outdoors.

[0021] According to one embodiment of this utility model, the upper cover is provided with a first locking hole, and the upper base is provided with a second locking hole at a position corresponding to the first locking hole. When the upper cover is in a horizontal position, the first locking hole and the second locking hole are aligned, and the locking device can be inserted into the through hole formed by the cooperation of the first locking hole and the second locking hole to complete the locking. This design has a simple structure, which allows users to quickly and reliably lock or unlock when the upper cover is in a horizontal state, improving operational convenience.

[0022] According to one embodiment of the present invention, the first lock hole is opened on the top wall or outer peripheral surface of the upper cover, and the corresponding second lock hole is provided on the top or side wall of the upper base, with the second lock hole and the second shaft hole being misaligned.

[0023] According to one embodiment of the present invention, a torsion spring and / or a helical spring are provided between the upper top cover and the upper base. The torsion spring and / or the helical spring have an elastic force that drives the upper top cover to rebound to a horizontal state, which facilitates a quick return to a stationary mode after the rocking chair state is released, thereby improving operational comfort.

[0024] According to one embodiment of this utility model, the locking device includes a locking member and an anti-loss rope. The locking member is inserted into the through hole, and the anti-loss rope is used to fix the locking member to the upper support assembly or the lower support assembly. By providing the anti-loss rope, the locking member is left on the upper support assembly or the lower support assembly during use and is not easily lost, resulting in high structural reliability.

[0025] According to one embodiment of this utility model, the upper base is provided with a stop portion with a height difference at its upper end. When the upper cover is in a horizontal position, a gap H is formed between its top wall and the lowest point of the stop portion, thereby reserving space for the upper cover to swing back and forth. This design ensures that the upper cover has sufficient space to swing back and forth in the unlocked state.

[0026] According to one embodiment of this utility model, the upper base and the lower base are connected by vertically arranged connecting bolts, and the upper base can rotate relative to the lower base around the connecting bolts. That is, the upper support assembly can rotate relative to the lower support assembly around a vertical axis, giving the folding rocking chair a self-rotating function.

[0027] According to one embodiment of this utility model, the lower base is provided with a shouldered bushing at its top. The shouldered bushing is circumferentially fixed relative to the lower base and contacts the bottom of the upper base to allow the upper base to rotate around the connecting bolt. The shouldered bushing design improves the support stability and wear resistance of the rotating components, extending the product's service life.

[0028] According to one embodiment of this utility model, a limiting member is elastically installed at one end of the lower connecting rod near the lower base. The limiting member can reciprocate along the length of the lower connecting rod. The lower base is provided with a positioning part. When the lower connecting rod is in a folded state, the limiting member is inserted into the positioning part, providing resistance to the rotation of the lower connecting rod relative to the lower base. This design can effectively limit the swaying of the lower connecting rod in the folded state, ensuring stability and safety during storage and transportation.

[0029] According to one embodiment of this utility model, a retaining spring that can move unidirectionally along the length direction is provided inside the lower connecting rod, and a return spring is provided between the retaining spring and the limiting member, with one end of the return spring abutting against the retaining spring and the other end abutting against the limiting member; or

[0030] The lower connecting rod is nested with a connecting arm. The limiting member can slide along the length direction of the connecting arm. The connecting arm is provided with a unidirectional movable retaining spring. A return spring is provided between the retaining spring and the limiting member. One end of the return spring abuts against the retaining spring, and the other end abuts against the limiting member.

[0031] According to one embodiment of this utility model, the folding rocking chair further includes a chair cover, which is installed on the folding rocking chair frame. By combining the chair cover with the folding rocking chair frame, a complete foldable rocking chair is formed, meeting the needs of outdoor use and combining comfort and portability.

[0063] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0064] like Figure 1-14 As shown, this embodiment discloses a folding rocking chair frame, including an upper support assembly 10, a lower support assembly 20, and a locking device 30.

[0065] Combination Figure 2-4 As shown, the upper support assembly 10 includes an upper top cover 11, an upper base 13, and a plurality of upper connecting rods 12. One end of each of the plurality of upper connecting rods 12 is connected to the upper top cover 11 and is capable of rotating relative to the upper top cover 11, thereby allowing the upper top cover 11 to change angles during use. The upper top cover 11 can swing back and forth between a horizontal position and a downward swing position relative to the upper base 13 to provide a rocking chair function.

[0066] Combination Figure 12-14As shown, the lower support assembly 20 includes a lower base 21 and multiple lower connecting rods 22. One end of each lower connecting rod 22 is connected to the lower base 21 and can rotate relative to the lower base 21, allowing the lower support assembly 20 to be folded or unfolded. The upper base 13 is fixedly connected to the lower base 21 through a connecting structure, thereby ensuring that the upper support assembly 10 is stably installed on the lower support assembly 20.

[0067] The locking device 30 is used to connect the upper top cover 11 to the upper base 13 in the locked state, so that the upper top cover 11 is kept in a horizontal position to limit the back and forth swinging; in the unlocked state, the upper top cover 11 is allowed to swing freely relative to the upper base 13, realizing the switching from the static mode to the rocking chair mode.

[0068] Furthermore, combined Figure 4 As shown, the upper cover 11 is connected to at least three upper connecting rods 12, which can be telescopic or non-telescopic. In this embodiment, both the upper connecting rods 12 and the lower connecting rods 22 adopt a telescopic rod structure to reduce the volume when folded and stored. The four lower connecting rods 22 are of equal length, and the two front connecting rods 12 are shorter than the two rear connecting rods 12, with the two rear connecting rods 12 serving as backrest support rods. The upper ends of the four upper connecting rods 12 are used to connect the four corners of the chair fabric. Correspondingly, four upper opening slots 11b are provided on the outer periphery of the upper cover 11, and the four upper opening slots 11b are arranged in a cross shape.

[0069] The upper cover 11 and the lower base 21 are connected by a horizontally arranged first rotating shaft 15. The outer circumferential surface of the upper cover 11 is provided with two coaxial first shaft holes 11d, and the upper base 13 is provided with a second shaft hole 132a at the corresponding position. The first rotating shaft 15 passes through the first shaft hole 11d and the second shaft hole 132a in sequence to realize the back-and-forth swing connection between the upper cover 11 and the lower base 21.

[0070] Furthermore, combining Figure 5 As shown, the upper base 13 includes a cylindrical base 131, a support column 132 extending upward from the upper end of the base 131, and a limiting flange 133 disposed between the base 131 and the support column 132. The support column 132 has a vertically provided second locking hole 132b, the opening of the second locking hole 132b facing upward, and the upper end surface of the support column 132 forms a stop portion 132c with a height difference. The upper top cover 11 has a top wall 11a and a side wall surrounding the edge of the top wall 11a, forming a cavity with a downward opening. The limiting flange 133 and the side wall of the upper top cover 11 mutually limit each other, thereby limiting the horizontal displacement of the upper top cover 11 and reducing the force on the first rotating shaft 15.

[0071] Combination Figure 6As shown, a central shaft column 134 is vertically arranged inside the support column 132. The central shaft column 134 is arranged along the central axis of the upper base 13 and has a vertical hole inside. The lower base 21 has a central hole 21a. The vertical hole on the central shaft column 134 is aligned with the central hole 21a, thereby ensuring that the two are installed coaxially and improving the load-bearing stability.

[0072] Specifically, in combination Figure 7-8 As shown, the top wall 11a of the upper cover 11 is provided with a first locking hole 11c, and the upper base 13 is provided with a second locking hole 132b at a position corresponding to the first locking hole 11c. When the upper cover 11 is in a horizontal position, the first locking hole 11c and the second locking hole 132b are aligned, and the locking device 30 is inserted into the through hole formed by the combination of the first locking hole 11c and the second locking hole 132b to complete the locking. The locking device 30 includes a locking member 31 and an anti-loss rope 32. The locking member 31 is a pin, and one end of the anti-loss rope 32 is connected to the upper cover 11, and the other end is connected to the pin, so that the pin can remain on the upper support assembly 10. When the pin is inserted into the through hole, it can restrict the relative rotation between the upper cover 11 and the upper base 13 to achieve stable locking.

[0073] In another embodiment, the first locking hole 11c can be formed on the outer peripheral surface of the top cover 11, and the corresponding second locking hole 132b is provided on the side of the support post 132 so that the user can insert and remove the device from the side.

[0074] Specifically, in combination Figure 4 As shown, a torsion spring 14 is provided between the upper cover 11 and the upper base 13. The torsion spring 14 has an elastic force that drives the upper cover 11 to spring back to a horizontal state. The torsion spring 14 is sleeved on the first rotating shaft 15, and the elastic end of the upper end of the torsion spring 14 abuts against the top wall 11a of the upper cover 11. When the upper cover 11 swings downward, the torsion spring 14 deforms and stores energy; when the external force is released, the torsion spring 14 springs back to reset the upper cover 11 to a horizontal position.

[0075] Specifically, in combination Figure 8 As shown, the height-differential stop 132c at the upper end of the upper base 13 forms a gap H between the upper top cover 11 and the top wall 11a when the upper top cover 11 is horizontal, thus reserving space for the upper top cover 11 to swing back and forth, ensuring the freedom of back and forth swing while avoiding structural interference. The upper base 13 is connected to the lower base 21 by a vertical connecting bolt 24. The upper base 13 can rotate relative to the lower base 21 around the connecting bolt 24, realizing the self-rotation function of the folding rocking chair and facilitating the adjustment of the usage angle. A shouldered bushing 23 is provided at the top of the lower base 21. The shouldered bushing 23 is circumferentially fixed to the lower base 21 and contacts the bottom of the upper base 13 to allow the upper base 13 to rotate on the connecting bolt 24.

[0076] Furthermore, combined Figure 12As shown, the shouldered bushing 23 is made of wear-resistant plastic, while the upper base 13 and lower base 21 are made of aluminum alloy or engineering plastic to meet the load-bearing strength requirements. The shouldered bushing 23 is embedded between the upper base 13 body 131 and the lower base 21, and the bushing portion 23d of the shouldered bushing 23 mates with the central hole 21a of the lower base 21. A recessed groove 21b is formed at the upper end of the lower base 21, and multiple positioning pins 21c are provided within the groove 21b. The outer shoulder of the shouldered bushing 23 has an outer step 23a, the step surface of which abuts against the lower edge of the upper base 13; the smaller diameter circle matches the groove 21b, and the larger diameter circle matches the outer edge of the upper base 13. The shouldered bushing 23 has a recessed groove 23b at its upper end and multiple positioning holes 23c at its lower end. When the shouldered bushing 23 is inserted into the mating groove 21b, the positioning pins 21c are inserted into the positioning holes 23c to restrict the bushing from rotating relative to the lower base 21. The upper base 13 has a boss 131a at its lower end. The boss 131a is inserted into the recessed groove 23b and can rotate within it to achieve smooth rotation and reduce wear.

[0077] Specifically, in combination Figure 13 As shown, a limiting member 26 is elastically installed at one end of the lower connecting rod 22 near the lower base 21. The limiting member 26 can reciprocate along the length of the lower connecting rod 22. A positioning part 21d is provided on the lower base 21. When the lower connecting rod 22 is in the folded state, the limiting member 26 is inserted into the positioning part 21d, providing resistance to the rotation of the lower connecting rod 22 relative to the lower base 21, and ensuring the stability of the folded state.

[0078] Furthermore, combined Figure 14 As shown, a connecting arm 25 is nested inside the upper end of the lower connecting rod 22. The connecting arm 25 adopts a hollow sleeve design, with a cross-section matching the inner hole of the lower connecting rod 22, and is made of engineering plastic. The length of the connecting arm 25 is shorter than the length of the lower connecting rod 22. A lateral slotted hole 26a is opened on the limiting member 26, and the second rotating shaft 28 passes through the lower connecting rod 22, the connecting arm 25, and the slotted hole 26a. A return spring 27 is provided inside the connecting arm 25. One end of the return spring 27 abuts against the limiting member 26, and the other end abuts against the retaining spring 29 inside the lower connecting rod 22, thereby giving the limiting member 26 reciprocating elasticity along the direction of the lower connecting rod 22. The limiting member 26 is partially embedded in the connecting arm 25, and the other part has a top end 26b and a slope 26c. When the lower connecting rod 22 is unfolded, the slope 26c abuts against the side wall of the lower base 21 and is restrained by force, improving the overall structural stability.

[0079] Combination Figure 18As shown, a retaining spring 29 structure is provided in this embodiment, and the lower connecting rod 22 adopts a square tube design. Correspondingly, the connecting arm 25 is also designed as a square tube structure. The retaining spring 29 abuts against the side wall at the diagonal position inside the lower connecting rod 22 and can only be inserted into the lower connecting rod 22 in one direction. Specifically, along the length direction of the lower connecting rod 22, the retaining spring 29 can only be inserted from bottom to top. When attempting to insert it from top to bottom, both ends of the retaining spring 29 will abut against the inner wall of the lower connecting rod 22, thereby forming a one-way limit and preventing the retaining spring 29 from moving downward. In this way, after the retaining spring 29 is inserted into the lower connecting rod 22 from bottom to top, the lower end of the return spring 27 can abut against the retaining spring 29 for limitation, thereby avoiding the need to open holes on both sides of the lower connecting rod 22 and / or on both sides of the connecting arm 25, improving the overall aesthetics of the structure.

[0080] Similarly, in other embodiments, the retaining ring 29 can also be inserted into the connecting arm 25 from bottom to top to limit the position of the return spring 27, without needing to open holes on both sides of the connecting arm 25. In other embodiments, the lower connecting rod 22 can be designed as a round or elliptical tube, with the retaining ring 29 abutting against the side wall of the lower connecting rod 22.

[0081] Combination Figure 15-17 As shown, in another embodiment, the upper base 13 is provided with a mounting groove 132d, which is located on the side of the support column 132 away from the second locking hole 132b, for mounting a helical spring 16. The lower end of the helical spring 16 is embedded in the mounting groove 132d, and the upper end acts on the top wall 11a of the upper cover 11. The helical spring 16 and the torsion spring 14 work together to drive the upper cover 11 back to a horizontal state, which can provide stronger support for the upper cover 11.

[0082] Work style:

[0083] During the use of the folding rocking chair frame, the lower support assembly 20 is first unfolded, and the four lower connecting rods 22 are fixed in the support position by the limiting member 26. Then, the upper support assembly 10 is unfolded, and the upper connecting rods 12 support the chair fabric (not shown in the figure), forming a load-bearing seat structure. If the user wants the chair to remain stationary, the pin of the locking device 30 is inserted into the through hole formed by the upper top cover 11 and the upper base 13, keeping the upper top cover 11 horizontal and preventing it from swinging. If the user wants to switch to rocking chair mode, the locking device 30 is unlocked, and the torsion spring 14 allows the upper top cover 11 to swing back and forth between the horizontal position and the downward position. The user can achieve the swinging by applying slight gravity or external force. After use, the upper connecting rods 12 and the lower connecting rods 22 are folded in sequence, and the limiting member 26 is inserted into the positioning part 21d of the lower base 21, and the entire structure is folded up, achieving convenient storage and carrying.

[0084] In another embodiment, a folding rocking chair is disclosed, which also includes a chair cover mounted on the aforementioned folding rocking chair frame. Specifically, the four corners of the chair cover are connected to the upper ends of four upper connecting rods 12. When the folding rocking chair is folded, the four lower connecting rods 22 are first retracted and folded downwards. Then, the upper support assembly 10 is rotated to retract the four upper connecting rods 12 and position them between two adjacent lower connecting rods 22. Finally, the four upper connecting rods 12 are folded downwards, with the upper connecting rods 12 and lower connecting rods 22 staggered.
