Description

Technical Field

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

[0002] Rocking chairs, a popular type of chair, have become widespread in the furniture industry. To facilitate storage and portability, foldable rocking chairs have also appeared on the market. These common folding rocking chairs typically feature an integrated curved base rod on the ground. This curved base rod needs to be of a certain length to ensure the comfort of the rocking motion. However, existing folding rocking chair frames, such as the one disclosed in Chinese Patent Publication No. CN214631104U, have a backrest rod that partially overlaps the curved base rod in the vertical direction when folded. This results in the folded rocking chair being longer than the curved base rod in the front-to-back direction, and also preventing it from being tightly folded together vertically. Consequently, the folded rocking chair is quite bulky and still occupies a significant amount of space. Furthermore, folding or unfolding existing folding rocking chairs requires the operation of multiple parts, making the process cumbersome and inconvenient, and the folding or unfolding speed is slow.

[0031] See Figure 1-11As shown in the figure, as an embodiment of the present invention, a highly foldable rocking chair is provided, including two parallel side frames 1 that can be folded up and down. A foldable seat crossbar 2 and back crossbar 3 are arranged between the two side frames 1. A chair cushion is laid on top of the seat crossbar 2 and back crossbar 3 for the user to sit and lean against. The side frame 1 includes an arc-shaped base rod 11, side crossbars 12, armrests 13, and backrests 14. A connecting rod assembly is rotatably connected between the rear bottom end of the side crossbar 12 and the rear end of the arc-shaped base rod 11. The front bottom end of the side crossbar 12 is hinged to the front end of the arc-shaped base rod 11. The front and rear ends of the armrests 13 are... The top of the front side of the side cross bar 12 and the bottom side of the backrest bar 14 are respectively hinged. The middle part of the upper rear side of the side cross bar 12 is hinged to the lower side of the backrest bar 14. The limiter 17 is fixedly installed on the lower rear side of the side cross bar 12. The bottom end of the backrest bar 14 is blocked and limited by the limiter 17. The seat cross bar 2, back cross bar 3, and side cross bar 12 are all X-shaped folded cross bars. That is, the arc-shaped bottom bar 11, the side cross bar 12, and the connecting rod assembly form a first four-bar linkage mechanism with four hinge points. The armrest bar 13, the backrest bar 14, and the side cross bar 12 form a second four-bar linkage mechanism with four hinge points.

[0032] When the folding rocking chair switches from the unfolded state to the folded state, the backrest rod 14 swings forward and downward, gradually becoming horizontal to approach the armrest rod 13, which in turn causes the armrest rod 13 to move downward. The linkage assembly swings backward and downward, the side cross rod 12 folds down, and the back cross rod 3 swings forward and downward, gradually becoming horizontal to approach the seat cross rod 2. The seat cross rod 2 and the back cross rod 3 fold down to the left and right. Finally, the side cross rod 12, armrest rod 13, and backrest rod 14 are all folded down above the curved base rod 11, and the backrest rod 14, side cross rod 12, armrest rod 13, and curved base rod 11 are all closely clustered together vertically. The back cross rod 3 is folded down above the seat cross rod 2, completing the folding process of the folding rocking chair. When the folding rocking chair is in the folded state, the projections of the backrest rod 14, the side cross rods 12, and the armrest rods 13 in the vertical direction are all located within the arc-shaped base rod 11. This ensures that the length of the folding rocking chair in the front-to-back direction does not exceed the length of the arc-shaped base rod 11 after folding. At the same time, because it can also be highly clustered and closely stacked in the vertical direction, the folding rocking chair has a smaller volume after folding, reducing the space occupied and facilitating storage and transportation. Furthermore, through the structural design of the first four-bar linkage and the second four-bar linkage, the operation control of the backrest rod 14 enables all rods to achieve simultaneous clustering, folding, or unfolding operations at one time, greatly simplifying the operation steps. Folding or unfolding operations are simple and convenient, and the folding or unfolding speed is faster.

[0033] The first four-bar linkage serves as the chassis stabilization mechanism of the folding rocking chair, while the arc-shaped base rod 11 serves as the base for the arc-shaped slide rail of the folding rocking chair, providing the rocking function and also acting as a fixing member of the first four-bar linkage. The side-standing cross rod 12 includes a front support rod 121 and a rear support rod 122 that are hinged together in an X-shape. The first four-bar linkage, through the closed-loop structure formed by the four hinge points, ensures that the arc-shaped base rod 11, the front support rod 121, the rear support rod 122, and the linkage assembly of the first four-bar linkage are folded and retracted synchronously during folding, making it more stable and reliable.

[0034] The second four-bar linkage serves as the folding drive mechanism for the seat crossbar 2 and back crossbar 3. During folding, the armrest bar 13 acts as the active lever, driving the backrest bar 14 downwards. The backrest bar 14 is rotatably connected to the armrest bar 13 and the front support bar 121 through two hinge points, but not to the rear support bar 122, thus avoiding component interference. Simultaneously, the cantilever design of the backrest bar 14 allows the back crossbar 3 to fold and retract independently, improving independence and avoiding structural conflicts. The two four-bar linkages work together to achieve synchronous folding of each component, resulting in faster folding.

[0035] The first four-bar linkage controls the folding and retraction of the chassis area of ​​the folding rocking chair, while the second four-bar linkage controls the folding and retraction of the seat and back area. Synchronous movement is achieved through the linkage of the rear support rod 122 and the armrest rod 13. The folding path is optimized, and the arc-shaped bottom rod 11 serves as a folding guide for each rod, which lowers the overall center of gravity after folding, improves the compactness of storage, and naturally forms the swing path of the folding rocking chair when unfolded.

[0036] Among them, the seat cross bar 2 includes seat support bars 21 that are hinged in an X-shape to enhance the bending resistance of the seating area of ​​the folding rocking chair, and the back cross bar 3 includes back support bars 31 that are hinged in an X-shape to enhance the bending resistance of the backrest area of ​​the folding rocking chair. The cross design of the support bars achieves high rigidity with minimal weight and automatically folds together with the rotation of the bars when folding.

[0037] In this embodiment, the limiting member 17 has a limiting groove 171 with openings on the top and rear sides. When the folding rocking chair is in the unfolded state, the bottom end of the backrest rod 14 abuts against the limiting groove 171, thereby providing stable support for the folding rocking chair in the unfolded state. When the folding rocking chair is folded, the bottom end of the backrest rod 14 swings backward and moves upward out of the limiting groove 171.

[0038] In this embodiment, the left and right ends of the bottom side of the back cross bar 3 are respectively hinged to the top of the rear side of the two side cross bars 12, and the left and right ends of the top side of the back cross bar 3 are respectively hinged to the upper side of the two backrest bars 14. This makes the distance between the top of the backrest bar 14 and the top of the rear side of the side cross bar 12 gradually increase when the side stand 1 is folded, thereby driving the back cross bar 3 to fold and retract left and right.

[0039] In this embodiment, the left and right ends of the front side of the seat crossbar 2 are respectively hinged to the top of the front side of the two side upright crossbars 12, and the left and right ends of the rear side of the seat crossbar 2 are respectively hinged to the inner side of the bottom end of the two backrest bars 14. This allows the bottom end of the backrest bar 14 to swing and move upwards backwards during the folding process of the side uprights 1, thereby causing the left and right ends of the rear side of the seat crossbar 2 to move backwards, and thus causing the seat crossbar 2 to fold and retract left and right.

[0040] In this embodiment, a first support rod assembly is also included, comprising two left and right hinged first support rods 4. The ends of the two first support rods 4 that are far apart from each other are respectively laterally hinged to the middle of the left and right rods on the front side of the seat cross rod 2. The other end of one of the first support rods 4 is fixedly installed with a first positioning sleeve 5, and the other end of the other first support rod 4 is laterally hinged to the first positioning sleeve 5. The first positioning sleeve 5 is provided with a first slotted buckle structure 51 for locking and limiting the other first support rod 4. When the two first support rods 4 of the first support rod assembly are unfolded to the left and right to achieve lateral locking, they can form left and right unfolding support for the seat cross rod 2, preventing the seat cross rod 2 from deforming, maintaining the tension of the folding rocking chair in the seating area, and thus ensuring the support stability of the folding rocking chair in the unfolded state. In the unfolded state, the seat cross rod 2 and the first support rod assembly form a spatial truss structure, which makes the load-bearing more even and improves the load-bearing reliability of the folding rocking chair in the seating area.

[0041] In this embodiment, a second support rod assembly is also included, comprising two second support rods 6 hinged left and right. The ends of the two second support rods 6, which are far apart from each other, are longitudinally hinged to the middle of the left and right sides of the upper side of the back cross rod 3. One second support rod 6 has a second positioning sleeve 7 fixedly installed at its other end, and the other end of the other second support rod 6 is longitudinally hinged to the second positioning sleeve 7. The second positioning sleeve 7 is provided with a second slotted buckle structure 71 for locking and limiting the other second support rod 6. When the two second support rods 6 of the second support rod assembly are unfolded left and right to achieve lateral locking, they can provide lateral unfolding support for the back cross rod 3, preventing deformation of the back cross rod 3, maintaining the tension of the folding rocking chair in the backrest area, and distributing the load of the folding rocking chair in the seating area to prevent collapse. This ensures the support stability of the folding rocking chair in the unfolded state. Furthermore, in the unfolded state, the back cross rod 3 and the second support rod assembly form a spatial truss structure, resulting in more even load distribution and improved load-bearing reliability of the folding rocking chair in the backrest area. The first support rod assembly and the second support rod assembly share the same structural principle.

[0042] In this embodiment, a reinforcing sleeve 8 is fixedly installed at the top of the front side of the side cross bar 12. The left and right ends of the front side of the seat cross bar 2 are respectively hinged to the inner side of the reinforcing sleeve 8 on the two side cross bars 12. The front end of the armrest bar 13 is hinged to the outer side of the reinforcing sleeve 8 on its corresponding side cross bar 12, thereby preventing interference between the bars during the folding or unfolding of the folding rocking chair, and improving the overall structural stability and support effect.

[0043] In this embodiment, the linkage assembly includes a linkage limiting seat 15 and a linkage 16. The linkage limiting seat 15 is fixedly installed on the rear side of the arc-shaped bottom rod 11. An L-shaped groove 151 for blocking and limiting the linkage 16 is provided on the upper side of the linkage limiting seat 15. The bottom end of the arc-shaped bottom rod 11 is hinged in the L-shaped groove 151, and the top end of the arc-shaped bottom rod 11 is hinged to the bottom end of the rear side of the side upright cross rod 12. When the side upright frame 1 is folded, the side upright cross rod 12 will push the linkage 16 to make the top end of the linkage 16 swing backward and downward, thereby ensuring that the side upright cross rod 12 can smoothly fold downward and retract. Conversely, when the side upright frame 1 is unfolded, the side upright cross rod 12 will pull the linkage 16 to make the top end of the linkage 16 swing forward and upward, thereby ensuring that the side upright cross rod 12 can smoothly unfold upward.

[0044] L-shaped parts 10 are fixedly installed on the inner side of the reinforcing sleeve 8, the inner side of the bottom end of the backrest rod 14, and the inner side of the rear end of the front support rod 121. A U-shaped part 9 is fixedly installed on the upper side of the backrest rod 14. The left and right ends of the front side of the seat cross rod 2 are respectively hinged to the L-shaped parts 10 on the inner side of the reinforcing sleeve 8. The left and right ends of the rear side of the seat cross rod 2 are respectively hinged to the L-shaped parts 10 on the inner side of the bottom end of the backrest rod 14. The left and right ends of the lower side of the back cross rod 3 are respectively hinged to the L-shaped parts 10 on the inner side of the rear end of the front support rod 121. The left and right ends of the upper side of the back cross rod 3 are respectively hinged to the U-shaped parts 9 on the upper side of the backrest rod 14. The U-shaped parts 9 and L-shaped parts 10 serve as standardized connecting parts to reduce processing costs while ensuring the movement accuracy and flexibility of each rod.
