Description

Technical Field

[0001] This application relates to the field of furniture, and in particular to a recliner. Background Technology

[0002] A recliner is a type of leisure furniture designed for lying down. Compared to traditional chairs, it allows for greater relaxation, enabling the body to relax and rest in a semi-sleepy state. Therefore, it is widely used as a hospital companion chair, a nap chair, and an outdoor leisure chair. Folding recliners, in particular, are widely used for travel, leisure, and office naps due to their convenience, flexibility, small footprint, and portability.

[0003] In related technologies, such as Chinese Patent Publication No. CN204273813U, a wheeled recliner is disclosed, including a chair frame. The front and rear ends of the chair frame have two front legs and two rear legs, respectively. A seat frame and a back frame are installed on the chair frame. A seat cloth and a back cloth are respectively installed on the seat frame and the back frame. The back frame is rotatably mounted on the inner wall of the chair frame through an angle adjustment mechanism. The back frame includes two side rods and a crossbar set at the top of the side rods. The angle adjustment mechanism is installed on the inner wall of the side rods. The angle adjustment mechanism includes an adjustment frame and adjustment brackets installed on both sides of the adjustment frame. The adjustment bracket includes multiple protrusions and a groove is formed between two adjacent protrusions. A support rod is provided on the inner wall of the rear end of the seat frame. The shape and size of the support rod match the groove.

[0004] Regarding the aforementioned technologies, when the backrest of the wheeled recliner is folded, the angle adjustment mechanism causes two protrusions on the backrest, which occupy additional storage space during transport, and there is still room for improvement. Utility Model Content

[0005] In order to improve the problem that the angle adjustment mechanism causes two protrusions on the back frame, which occupy extra storage space during transportation, this application provides a recliner.

[0006] The recliner provided in this application adopts the following technical solution:

[0007] A recliner includes a seat frame, a backrest rotatably connected to the seat frame, a seat cover on the seat frame, a back cover on the backrest, and an adjustment frame on the backrest. The adjustment frame includes two side rods rotatably connected to the two sides of the backrest and two adjustment blocks for adjusting the rotation angle of the backrest. Each side rod has a cavity, and the side wall of the side rod has a first positioning hole and a second positioning hole. The end of each adjustment block is embedded in and rotatably connected to the cavity, and is fixedly connected to a first spring plunger. When the plunger of the first spring plunger passes through the first positioning hole, the adjustment block is in the working state; when the plunger of the first spring plunger passes through the second positioning hole, the adjustment block is in the retracted state.

[0008] By adopting the above technical solution, the adjusting block cooperates with the first positioning hole and the second positioning hole of the side rod through the first spring plunger. In the working state, by passing the plunger of the first spring plunger through the first positioning hole, the adjusting block can adjust and fix the back frame angle, realizing the normal use of the recliner. When the back frame needs to be folded, the adjusting block is rotated so that the plunger of the first spring plunger passes through the second positioning hole. At this time, the side wall of the adjusting block away from the back fabric is flush with the side rod, avoiding the space occupation problem caused by the exposed protrusion of the traditional angle adjustment mechanism. This makes the back frame flatter and more compact after folding, saving storage space.

[0009] Optionally, the adjusting block is provided with a plurality of grooves distributed along the length direction of the side rod, and the seat frame is integrally provided with an extension frame on the side near the back frame, and a support rod for fitting the grooves is fixedly connected to the extension frame.

[0010] By adopting the above technical solution, when the backrest rotates, the adjusting block rotates synchronously with the backrest, and the grooves at different positions are fitted onto the support rod. The tilt angle of the backrest is fixed by the engagement of the grooves with the support rod, which meets the needs of users in different lying positions and improves the convenience of users to adjust the angle of the backrest.

[0011] Optionally, the adjusting block includes a connecting part rotatably connected to the side rod and an adjusting part detachably connected to the connecting part.

[0012] By adopting the above technical solution, when the groove wall on the adjusting block is worn and the adjusting block cannot stabilize the rotation angle of the back frame, the adjusting part can be directly removed from the connecting part for replacement, without having to remove the entire adjusting block from the measuring rod, thus improving the convenience of user maintenance of the adjusting block.

[0013] Optionally, the adjustment frame may further include a crossbar connecting the two side bars.

[0014] By adopting the above technical solution, the two side rods are fixedly connected by a crossbar, so that the two measuring rods rotate synchronously. This eliminates the need for the user to adjust and lock the rotation angle of the back frame by rotating the two side rods one by one, thus improving the convenience of the user in adjusting the angle of the back frame.

[0015] Optionally, a reinforcing rib is fixedly connected to the side rod, and the end of the reinforcing rib away from the side rod is fixedly connected to the crossbar.

[0016] By adopting the above technical solution and adding reinforcing ribs to increase the connection strength between the side bars and the crossbar, the stability of the user adjusting the two side bars simultaneously via the crossbar is improved.

[0017] Optionally, the seat frame is rotatably connected to at least four legs on the side away from the back frame. The seat frame is provided with a first limiting hole and a second limiting hole corresponding to each leg. A second spring plunger is fixedly connected to each leg. When the plunger of the second spring plunger passes through the first limiting hole, the leg is in the working state. When the plunger of the second spring plunger passes through the second limiting hole, the leg is in the retracted state.

[0018] By adopting the above technical solution, the working state and storage state of the support legs can be easily switched through the cooperation of the second spring plunger with the first and second limiting holes on the seat frame. When the recliner needs to be stored, the support legs can be folded and stored, avoiding the problem of the support legs taking up extra space due to being exposed when not in use, and further improving the storage performance of the recliner.

[0019] Optionally, each of the legs is provided with a foot pad at the end away from the seat frame.

[0020] By adopting the above technical solution, the foot pads are made of non-slip material, which can increase the friction with the ground, prevent the recliner from sliding during use, and improve the overall stability of the recliner during user use.

[0021] Optionally, both sides of the back frame are provided with mounting grooves that run along the length of the back frame and penetrate the back frame, and mounting rods for correspondingly embedding in the mounting grooves are fixedly connected to the back fabric.

[0022] By adopting the above technical solution, the back cover is installed on the back frame by embedding the mounting rod in the mounting groove. When the back cover needs to be removed, a force along the length of the mounting rod is applied. When the user lies on the recliner, the pressure applied to the back cover is perpendicular to the length of the mounting rod. The two are no longer in the same direction, which improves the stability of installing the back cover on the back frame.

[0023] Optionally, the end of the back frame that is penetrated by the mounting groove is provided with a sealing cap.

[0024] By adopting the above technical solution, after the mounting rod is embedded in the mounting groove, the sealing cover is installed at the end of the back frame to prevent dust from entering the mounting groove from the end of the back frame that is penetrated by the mounting groove, thereby improving the cleanliness of the inside of the back frame.

[0025] Optionally, a plurality of support rods for supporting the seat fabric are fixedly connected to the seat frame.

[0026] By adopting the above technical solution, the weight of the human body borne by the seat fabric is distributed by the support rod, which avoids the seat fabric from becoming loose, deformed or damaged due to long-term stress, thus extending the service life of the recliner.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By cooperating with the first spring plunger and the first and second positioning holes of the side rod, the working state and storage state of the adjustment block can be easily switched, saving storage space;

[0029] 2. The tilt angle of the backrest is fixed by the engagement of the support rod with the grooves at different positions, which meets the needs of users in different lying positions and improves the convenience of users to adjust the angle of the backrest;

[0030] 3. By adding reinforcing ribs, the connection strength between the side bars and the crossbar is increased, improving the stability for users to adjust both side bars simultaneously via the crossbar. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0040] This application discloses a reclining chair.

[0041] Reference Figure 1 The recliner includes a seat frame 1, a seat cover 2, a backrest frame 3, a backrest cover 4, and an adjustment frame 5. The seat cover 2 is installed on the seat frame 1 for the user to sit on. The backrest frame 3 is rotatably connected to the seat frame 1, and the backrest cover 4 is installed on the backrest frame 3 for the user to lean against. The adjustment frame 5 is installed on the backrest frame 3 to adjust the rotation angle of the backrest frame 3.

[0042] Reference Figure 1 and Figure 2 The back frame 3 includes two rotating rods 31 for mounting the back fabric 4 and a connecting rod 32 connecting the two rotating rods 31. The two rotating rods 31 are rotatably connected to both sides of the seat frame 1 to realize the rotatable connection between the back frame 3 and the seat frame 1.

[0043] Reference Figure 2 and Figure 3 The rotating rod 31 has a mounting groove 311 arranged along its length, which passes through both ends of the rotating rod 31 to facilitate the installation and removal of the backing cloth 4. Mounting rods 41 are fixedly connected to both sides of the backing cloth 4 near the rotating rod 31. When the mounting rods 41 are slid into the mounting grooves 311 from the ends of the rotating rod 31, the backing cloth 4 is mounted on the back frame 3. To prevent dust from entering the interior of the rotating rod 31 from the ends through which the mounting grooves 311 pass, both ends of the rotating rod 31 have sealing caps 42. The sealing caps 42 are made of plastic, and a snap-fit ​​block 421 for embedding inside the rotating rod 31 is integrally connected to the side near the rotating rod 31. The snap-fit ​​block 421 has a clearance groove 422 to avoid the mounting rod 41 and the groove wall of the mounting groove 311. The connecting rod 32 abuts against the side of the backing cloth 4 away from the user's support to support the backing cloth 4.

[0044] Reference Figure 2 and Figure 4 The adjusting frame 5 includes side rods 51, a crossbar 52, and an adjusting block 53. There are two side rods 51, each rotatably connected to one of two rotating rods 31. The two ends of the crossbar 52 are fixedly connected to the ends of the two side rods 51 furthest from the rotating rods 31, so that the two side rods 51 rotate synchronously when subjected to external force. To strengthen the connection between the side rods 51 and the crossbar 52, reinforcing ribs 54 are fixedly connected to both side rods 51, with the ends of the reinforcing ribs 54 furthest from the side rods 51 fixedly connected to the crossbar 52.

[0045] Reference Figure 4 and Figure 5 The adjusting block 53 includes a connecting part 531 and an adjusting part 532. The side rod 51 has a cavity 511 for mounting the connecting part 531, and the end of the connecting part 531 is embedded and rotatably connected within the cavity 511. A first spring plunger 5311 is fixedly connected to the connecting part 531. The side wall of the side rod 51 has a first positioning hole 512 and a second positioning hole 513. The adjusting part 532 and the connecting part 531 can be detachably connected via tenon and mortise, snap-fit, or other structures. In this embodiment, a bolt 5312 connection is used as an example. A bolt 5312 is threaded onto the connecting part 531, penetrating the adjusting part 532, and the head of the bolt 5312 abuts against the side of the adjusting part 532 away from the connecting part 531. The adjustment part 532 has several grooves 5321 distributed along the length of the side rod 51 on the side away from the connecting part 531. An extension frame 11 extends integrally from the side of the seat frame 1 near the back frame 3. A support rod 12 with an outer diameter that matches the inner diameter of the groove 5321 is fixedly connected to the extension frame 11. When the recliner is in use, the adjustment block 53 is rotated so that the plunger of the first spring plunger 5311 passes through the first positioning hole 512. Then, the adjustment frame 5 is rotated so that one of the grooves 5321 is fitted onto the support rod 12 to lock the rotation angle of the back frame 3. When the recliner is not in use, the adjustment block 53 is rotated so that the plunger of the first spring plunger 5311 passes through the second positioning hole 513. At this time, the side wall of the adjustment part 532 is flush with the side rod 51 so that the back frame 3 is more flat and compact after folding.

[0046] Reference Figure 6 To prevent the seat fabric 2 from becoming severely deformed due to prolonged pressure from the human body, several support rods 13 are fixedly connected to the seat frame 1. This application describes the use of three support rods 13. The three support rods 13 are installed parallel to each other and at equal intervals on the seat frame 1. All three support rods 13 are recessed towards the side away from the seat fabric 2 to conform to the curvature of the seat fabric 2 when the human body is lying down.

[0047] Reference Figure 6 and Figure 7The base frame 1 is also rotatably connected to at least four legs 14. This application describes the base frame 1 with four legs 14, which are respectively arranged at the four corners of the base frame 1 to stably support the base frame 1. To enhance the stability of the legs 14, a reinforcing rod 141 is fixedly connected to each leg 14, with each end of the reinforcing rod 141 fixedly connected to two adjacent legs 14 that are relatively close to each other. A second spring plunger 142 is fixedly connected to each leg 14, and the base frame 1 has a first limiting hole 15 and a second limiting hole 16 that correspond one-to-one with the second spring plunger 142. When the support leg 14 is rotated so that the plunger of the second spring plunger 142 passes through the first limiting hole 15, the support leg 14 is in the open working state, supporting the seat frame 1. When the support leg 14 is rotated so that the plunger of the second spring plunger 142 passes through the second limiting hole 16, the length direction of the support leg 14 is parallel to the plane on which the seat frame 1 is located, at which time the recliner can be stored and moved. To prevent the support leg 14 from sliding during the support of the seat frame 1, a foot pad 143 is fixedly connected to the end of each support leg 14 away from the seat frame 1. The foot pad 143 is made of rubber to increase the friction between the foot pad 143 and the ground.

[0048] The implementation principle of a recliner according to an embodiment of this application is as follows: When the recliner needs to be folded up, the adjustment frame 5 is lifted so that the groove wall of the groove 5321 is disengaged from the support rod 12. Then, the first spring plunger 5311 is pressed and the adjustment block 53 is rotated so that the plunger of the first spring plunger 5311 passes through the second positioning hole 513. At this time, the side of the adjustment part 532 away from the back fabric 4 is flush with the side rod 51. Then, the adjustment frame 5 is rotated so that the side rod 51 abuts against the back fabric 4. After pressing the second spring plunger 142, the support leg 14 is rotated so that the plunger of the second spring plunger 142 passes through the second limiting hole 16. At this time, the length direction of the support leg 14 is parallel to the plane where the seat frame 1 is located, and the entire recliner is folded up for easy storage and transportation.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
