Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a recliner with high stability. Background Technology

[0002] Recliners, as a common type of furniture, are widely used in homes and offices, providing convenience for rest and relaxation. Their function lies in the ability to adjust the backrest to different angles to meet the user's needs from sitting to lying down. For ease of movement, many recliners are also designed with multiple casters at the bottom. However, in actual use, existing recliners have revealed a lack of stability. When the user adjusts the backrest to a large reclining angle, the body's center of gravity shifts backward. For recliners with casters, the chassis is usually composed of multiple movable legs. This structure is prone to swaying when bearing the changing center of gravity, lacking a stable support and giving the user a sense of insecurity, seriously affecting the user experience.

[0003] Therefore, this utility model proposes a recliner with high stability to overcome the shortcomings of the prior art. Utility Model Content

[0004] In view of the problems of unstable chassis structure and easy wobbling when the backrest is tilted in the existing technology, and the safety risk of falling backward in the reclining chair, the present invention aims to provide a highly stable reclining chair with an improved structure that can effectively solve the above problems.

[0005] This utility model provides a high-stability recliner, comprising: a seat plate, a backrest rotatably connected to the rear side of the seat plate, a support column rotatably connected to the bottom of the seat plate, and a chassis assembly consisting of a central disc fixed to the bottom end of the support column and a plurality of movable rods radially connected to the central disc; as well as a movable disassembly mechanism and a support rod rotatably connected to the outer wall of the backrest on the movable rods.

[0006] The movable disassembly mechanism includes a button located on the outer wall of the movable rod, a sliding connecting plate fixedly connected to the button, and a limiting block fixed to the connecting plate.

[0007] Furthermore, the outer wall of the central disc has a slot that matches the limiting block. The button on the moving rod is used to drive the limiting block to extend the moving rod and engage with the slot of the central disc, thereby locking multiple moving rods into a stable whole. The support rod is used to extend to support the ground when the backrest is tilted at a large angle, preventing the recliner from tilting backward.

[0008] Preferably, the outer wall of the moving rod has a placement groove for accommodating the button and a moving groove for guiding the sliding of the connecting plate. The structure allows the components of the moving disassembly mechanism to be compactly integrated on the moving rod.

[0009] Preferably, the movable disassembly mechanism also includes an elastic metal disposed at the bottom of the connecting plate. The elastic metal provides a continuous rebound force after the limiting block is engaged in the slot, ensuring the tightness and reliability of the locked state.

[0010] Preferably, a fixing block is fixedly connected to the outer wall of the backrest, and the support rod is connected to the backrest by a rotating column three in the middle of the fixing block, providing a stable rotating base for the storage and unfolding of the support rod.

[0011] Preferably, the recliner also includes a backrest angle adjustment mechanism, which includes a pull rod rotatably connected to the outer wall of the backrest via a rotating column, a telescopic column rotatably connected to the outer wall of the seat, and a fixed column fixed to the top of the telescopic column; the bottom of the pull rod is provided with multiple limiting grooves, and the fixed column engages with the limiting grooves to lock the backrest at different tilt angles.

[0012] Preferably, the seat and backrest are rotatably connected by a connecting column and a rotating column, providing the main rotation axis for the tilting movement of the backrest.

[0013] Preferably, the recliner also includes a ring rotatably connected to the support column and a fixing rod fixedly connected to the outer wall of the ring and the bottom of the seat plate. The triangular support structure enhances the connection rigidity between the seat plate and the support column, and improves the stability of the middle part of the recliner.

[0014] Preferably, the support column has an internal structure similar to the movable disassembly mechanism, and a circular groove is provided at the bottom of the seat plate. Through the internal structure, the support column can be easily disassembled from the seat plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting up a movable disassembly mechanism, uses a button to drive the limit block to engage in the slot of the central disc, locking multiple moving rods into one piece, thus solving the problem of loose and easily shaking chassis structure of existing wheeled recliners, and achieving the technical effect of improving the overall rigidity and stability of the chassis.

[0017] 2. This utility model solves the problem of unstable center of gravity and risk of tipping over when the backrest is tilted by rotating a support rod connected to the backrest. This provides an additional support point, effectively prevents the recliner from tipping over, and improves the safety of use.

[0018] 3. This utility model, through its movable disassembly mechanism, can not only lock the chair but also easily detach the moving rod from the central disc, solving the problems of existing reclining chairs having an integrated structure, inconvenient disassembly and assembly, and large transportation and storage volume. It achieves the technical effects of easy disassembly, reduced packaging volume, and convenient transportation and storage. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 5 This utility model provides a high-stability recliner, including a seat 1 and a backrest 5 rotatably connected to the rear side of the seat 1. A support column 16 is rotatably connected to the bottom of the seat 1, and a chassis assembly is fixed to the bottom end of the support column 16. The chassis assembly includes a central disc 208 and a plurality of movable rods 201 radially connected to the central disc 208.

[0029] To achieve stable locking of the chassis, the recliner also includes a movable disassembly mechanism 2, which is mounted on a movable rod 201. Specifically, a placement groove 202 and a moving groove 207 are provided on the outer wall of the movable rod 201. The movable disassembly mechanism 2 includes a button 203, which is located in the placement groove 202; a connecting plate 204, one end of which is fixedly connected to the button 203 and slidably connected to the inner wall of the moving groove 207; and a limiting block 206, which is fixedly connected to the outer wall of the connecting plate 204.

[0030] The outer wall of the central disc 208 has a slot 209 that mates with the limiting block 206. By pressing the button 203, the connecting plate 204 and the limiting block 206 fixed on the connecting plate 204 can be moved downward together, so that the limiting block 206 extends out of the moving rod 201 and is engaged in the slot 209 of the central disc 208, thereby locking the moving rod 201 relative to the central disc 208. The moving and disassembling mechanism 2 also includes an elastic metal 205, which is disposed at the bottom of the connecting plate 204 and is used to limit the movement of the moving rod 201. After block 206 is inserted into slot 209, it provides a rebound force to ensure a secure and reliable lock. To prevent the backrest 5 from tipping over when reclining, the recliner also includes a support rod 13, which is rotatably connected to the outer wall of the backrest 5 via a rotating column 3 12. More specifically, a fixing block 11 is fixedly connected to the outer wall of the backrest 5, the rotating column 3 12 is rotatably connected to the middle of the fixing block 11, and the support rod 13 is fixedly connected to the rotating column 3 12. When the backrest 5 is tilted, the support rod 13 can be moved to contact the ground to provide an additional support point for the recliner.

[0031] Please refer to Figure 1 The recliner also includes an adjustment and locking assembly, which forms a specific structural fit and connection with the aforementioned seat plate 1 and backrest 5. The adjustment and locking assembly includes a pull rod 7, a telescopic column 9, and a fixed column 10. The pull rod 7 is rotatably connected to the outer wall of the backrest 5 via the rotating column 10. The bottom of the pull rod 7 has multiple limiting grooves 8 distributed along its length.

[0032] The bottom end of the telescopic column 9 is rotatably connected to the outer wall of the seat plate 1, and the top of the telescopic column 9 is fixedly connected to the fixing column 10. In the assembled state, the end of the fixing column 10 can be engaged with any of the limiting grooves 8 at the bottom of the pull rod 7. This engaging structure between the fixing column 10 and the limiting groove 8 ensures that when the backrest 5 is adjusted to the required tilt angle, it can be firmly locked to prevent accidental movement.

[0033] In a preferred embodiment, in order to form the basic rotatable connection of the backrest 5, the recliner also includes a connecting column 3 and a rotating column 4; the connecting column 3 is fixedly connected to the outer wall of the seat plate 1, the connecting column 3 is rotatably connected to the rotating column 4, and the rotating column 4 is rotatably connected to the backrest 5, thereby forming the main rotation axis of the backrest 5 that is inclined relative to the seat plate 1.

[0034] As another preferred embodiment, in order to enhance the connection rigidity between the seat plate 1 and the support column 16, the recliner also includes a ring 15 and a fixing rod 14; the ring 15 is rotatably connected to the outer periphery of the support column 16, one end of the fixing rod 14 is fixedly connected to the outer wall of the ring 15, and the other end is fixedly connected to the bottom of the seat plate 1. Through the fixing rod 14, the ring 15 and the support column 16 form a stable triangular support structure, which effectively improves the stability of the middle part of the recliner.

[0035] In another preferred embodiment, in order to facilitate the disassembly and assembly of the entire chair, the support column 16 has a structure similar to the movable disassembly mechanism 2. A circular groove 210 is correspondingly provided at the bottom of the seat plate 1, and the support column 16 can be detachably inserted into the circular groove 210 through its internal locking structure.

[0036] Working principle: When the tilt angle of the backrest 5 needs to be adjusted, the user pulls the lever 7. The lever 7 drives the backrest 5 to rotate backward around the connecting column 3 and the rotating column 4 on the rear side through the rotating column 2 6. After adjusting to the appropriate angle, the fixing column 10 at the top of the telescopic column 9 is inserted into the corresponding limiting groove 8 at the bottom of the lever 7 to lock the tilt angle of the backrest 5. When the backrest 5 is tilted to a large angle that allows for reclining, the support rod 13 rotatably connected to the outer wall of the backrest 5 is pushed down so that its end supports the ground, providing an additional rearward support point for the recliner, thereby preventing it from tilting backward and improving safety.

[0037] When the recliner needs to be secured for high stability, the user presses the button 203 on the moving rod 201. The button 203 causes the connecting plate 204 and the limiting block 206 fixed thereon to slide downward in the moving groove 207, so that the limiting block 206 extends out and engages in the slot 209 on the outer wall of the central disc 208. The elastic metal 205 at the bottom of the connecting plate 204 provides a rebound force during this process, ensuring that the limiting block 206 and the slot 209 are tightly engaged. When multiple moving rods 201 are locked to the central disc 208 in this way, the entire chassis forms a stable whole, eliminating relative movement between the components and thus solving the problem of chassis wobbling. Reverse operation of the button 203 can disengage the limiting block 206 from the slot 209, realizing the disassembly of the moving rod 201. Similarly, the support column 16 can also be disassembled from the circular groove 210 at the bottom of the seat plate 1 through a similar locking structure inside it.
