Description

Technical Field

[0001] This utility model relates to the technical field of home furnishing products, and in particular to a hardware frame for rotating seats. Background Technology

[0002] Currently, more and more home furnishing products come with adjustable seating functions, such as sofas, office chairs, or lounge chairs. Users hope to adjust the position of the seat cushion through the adjustment mechanism to change their sitting posture and obtain a more comfortable experience.

[0003] For example, when adjustment mechanisms are used in sofas, existing adjustment mechanisms generally have the following technical defects: First, it is difficult to effectively constrain and guide moving parts when adjusting the seat cushion, making it inconvenient for users to adjust the position of the seat cushion, resulting in greater operational difficulty; Second, in order to stably fix the sofa seat cushion, its locking structure is generally more complex, and when users need to adjust the position of the sofa seat cushion, they need to go through more cumbersome steps, resulting in a poor user experience. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned background technology, the present invention provides a seat rotation hardware frame that is easy to adjust the position of the seat cushion, can stably fix the seat cushion to ensure safe and reliable use, and is easy to operate when adjusting the position of the seat cushion.

[0005] The technical solution is: a hardware frame for seat rotation, comprising: The base plate has track one, track two, track three and track four on its surface; Pulley 1 and Pulley 2 are slidably disposed within track 4 and track 3, respectively; Pulley three is slidably disposed within track one and track two, and reciprocates between track one and track two; A support plate is provided on top of pulley one and pulley two; A connecting plate is disposed on one side of the support plate; A guide rail is provided on the inner wall of the connecting plate. A slide rail is provided inside the guide rail. A locking device is provided on the slide rail. The slide rail is movably connected to the pulley. The base plate is provided with locking holes for limiting the movement of the connecting plate and the support plate, and the locking holes are used to fit the locking components.

[0006] Furthermore, the card slot includes card slot one and card slot two.

[0007] Furthermore, track one and track two are integrally connected, while track three and track four are arranged at intervals.

[0008] Furthermore, the extension directions of track one and track two are perpendicular to each other, and the outer edge of their connection is set as an arc transition structure to achieve a smooth transition of pulley three.

[0009] Furthermore, the extension directions of the third track and the fourth track are different, and the distance between the third track and the fourth track gradually increases along their extension directions to form a flared structure, which is used to guide the movement of the second pulley and the first pulley, respectively.

[0010] Furthermore, the extension directions of the third track and the fourth track form an angle α, the value of which is between 40° and 48°.

[0011] Furthermore, the value of the included angle α is 43°.

[0012] Furthermore, the first locking hole is located beside the first track, and the second locking hole is located beside the second track.

[0013] Furthermore, the card has a circular cross-section, and its cross-sectional dimensions are adapted to the cross-sectional dimensions of the first card hole and the second card hole.

[0014] Furthermore, it also includes a pneumatic rod, the fixed end of which is located on the base plate, and the movable end of which is movably connected to the support plate.

[0015] The beneficial effects of this utility model are as follows: With the addition of connecting plates and clips, users can initiate the adjustment process simply by slightly lifting and pushing the sofa cushion. By using pulley one and pulley two to slide within tracks four and three respectively, this design ensures that the movement trajectory of the T-shaped support is effectively constrained and guided during rotation, allowing users to more easily adjust the position of the sofa cushion and reducing the difficulty of operation.

[0016] By using clips and different locking holes, the sofa cushions are stably fixed, preventing them from moving around and ensuring safety and reliability. The clips automatically engage with new locking holes without any additional operation, completing the locking process. This "lift-adjust-automatic locking" mechanism simplifies the sofa cushion adjustment process, allowing users to easily switch between sofa cushions with simple lifting and pushing actions, thus enhancing the user experience.

Detailed Implementation

[0024] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0025] Reference Figure 1-6 As shown, this utility model provides a hardware frame for seat rotation, including a base plate 1. The surface of the base plate 1 is provided with a first track 31, a second track 32, a third track 33, and a fourth track 34. A first pulley 41 is slidably disposed within the fourth track 34, and a second pulley 42 is slidably disposed within the third track 33. A support plate 43 is fixedly mounted on the top of the first pulley 41 and the second pulley 42 by screws. A connecting plate 51 is welded to one side of the support plate 43. A guide rail 52 is fixedly disposed on the inner wall of the connecting plate 51. In a preferred embodiment, two screws are used to fasten the guide rail 52 to the connecting plate 51. This method provides reliable connection and simple assembly. It is understood that... The fixing method of rail 52 is not limited to this. In other embodiments, a bolt and nut fastening method can also be used, thereby providing greater flexibility for installation and maintenance. A slide rail 53 is slidably arranged inside the guide rail 52. The slide rail 53 is equipped with a locking piece 61 by bolts. The connecting plate 51 is used to adjust the position of the locking piece 61. A pulley 34 is slidably arranged on the first track 31. The pulley 34 is movably connected to the slide rail 53. The base plate 1 has a locking hole 62 and a locking hole 63. The locking piece 61 is inserted into the locking hole 62 and fits against the outer wall 31 of the first track. In other embodiments, the connecting plate 51 and the support plate 43 can also be fixed by other methods.

[0026] Track 1 31 and Track 2 32 are connected as one unit, with an included angle of 90 degrees. The outer edge of the connection between Track 1 31 and Track 2 32 is set as an arc transition structure to achieve a smooth transition of Pulley 3 54. Track 3 33 and Track 4 34 are arranged at intervals, and the distance between Track 3 33 and Track 4 34 gradually increases along their length direction and is arranged in a flared manner, which are used to guide the movement of Pulley 2 42 and Pulley 1 41 respectively.

[0027] The extension directions of track 33 and track 44 form an included angle α11. The design of this included angle α11 directly affects the force distribution and motion trajectory stability of pulley 1 41 and pulley 2 42 during the movement process. It also relates to the overall layout and structural compactness of the hardware frame. After comprehensive design and verification, when the included angle α11 is between 40° and 48°, it can better balance the smoothness of rotation, structural stability and overall space occupation.

[0028] In a preferred embodiment, the included angle α11 is 43°. This specific angle value is optimized to ensure smooth movement of pulley 41 and pulley 42 while controlling the overall volume of the hardware frame to a suitable and compact size. This makes the structural layout of the hardware frame more reasonable, avoids unnecessary space waste, and facilitates the installation and arrangement of hardware in sofas and chairs of various sizes.

[0029] It is understandable that the specific value of the included angle α11 can be adaptively adjusted according to the structure and space requirements of different sofas, rather than being limited to a certain fixed value. For example, in some application scenarios with special restrictions on installation space, the included angle α11 can also adopt a nearby value such as 40°, 45° or 48° to achieve better adaptability.

[0030] Slot 1 62 is located next to track 1 31, and slot 2 63 is located next to track 2 32.

[0031] The cross-section of the card part 61 is circular, and the cross-sectional dimensions of the card part 61 are adapted to the cross-sectional dimensions of the card hole 62 and the card hole 63.

[0032] The connecting plate 51 is a spring steel plate. The connecting plate 51 is used to adjust the position of the clamp 61. In other embodiments, the connecting plate 51 may also be made of fiber-reinforced composite material, preferably carbon fiber reinforced composite material or glass fiber reinforced composite material.

[0033] It also includes a pneumatic rod 71, the fixed part of which is rotatably connected to the base plate 1. The movable end surface of the pneumatic rod 71 is provided with a connecting rod 72, which is slidably connected to the support plate 43. The pneumatic rod 71 is used to assist in pushing the support plate 43 and the connecting plate 51. Of course, in other embodiments, an electric push rod can be used instead of the pneumatic rod 71.

[0034] The connecting plate 51 and the support plate 43 constitute a T-shaped support. When the position of the T-shaped support needs to be adjusted, the user lifts the end of the connecting plate 51 near the pulley 54. The connecting plate 51 then tilts slightly upwards, causing the guide rail 52, slide rail 53, and locking piece 61 to move upwards. The locking piece 61 then leaves the locking hole 62. Next, the user pushes the connecting plate 51 and the support plate 43 to rotate 90 degrees counterclockwise, causing pulley 41 to move to the other side of track 34, pulley 42 to move to the other side of track 33, and pulley 54 to move into track 232. During the rotation of the connecting plate 51 and the support plate 43, pulley 54... The pulley 34 moves within the tracks 31 and 32. The pulley 54 drives the locking piece 61 to always contact the outer edges of the tracks 31 and 32 via the slide rail 53. The slide rail 53 slides within the guide rail 52. When the locking piece 61 moves along the surface of the base plate 1, it continuously lifts one end of the connecting plate 51. When the locking piece 61 moves above the locking hole 63, the base plate 1 no longer supports the locking piece 61, and the connecting plate 51 resets and locks the locking piece 61 into the locking hole 63, thereby completing the adjustment of the position of the T-shaped support. Through the cooperation of the locking piece 61 with different locking holes, the connecting plate 51 and the support plate 43 form a stable T-shaped support.

[0035] When pulley 3 54 slides along track 1 31, support plate 43 pushes the telescopic rod of pneumatic rod 71 to retract. When pulley 3 54 moves to the connection point of track 1 31 and track 2 32, the telescopic rod of pneumatic rod 71 retracts to its maximum. Then the user can stop pushing connecting plate 51 and rely on the thrust generated by the resetting of telescopic rod of pneumatic rod 71 to push connecting plate 51 and support plate 43 to continue to rotate counterclockwise until the locking piece 61 is locked into locking hole 2 63.

[0036] This hardware frame can be used to adjust sofa cushions. The frame is fixed to the sofa seat with bolts. The sofa support is then bolted onto the connecting plate 51 and support plate 43 to form a T-shaped support. Finally, the sofa cushion is fixed onto the sofa support. In actual use, if the position of the sofa cushion needs to be adjusted, the user can simply lift the side of the sofa cushion closest to the connecting plate 51 slightly, causing the clip 61 to disengage from the clip hole 62. The user can then push the sofa cushion to rotate counterclockwise by 45 degrees. With the push of the gas spring 71, the sofa cushion continues to rotate counterclockwise by 45 degrees to complete the reversal. Alternatively, the user can directly push the sofa cushion to rotate 90 degrees to complete the reversal. This is achieved through the setting of… With the connecting plate 51 and the locking clip 61, the user only needs to slightly lift and push the sofa cushion to start the adjustment process. At the same time, the push is assisted by the reset force of the gas spring 71, making the adjustment process more convenient and effortless, reducing the difficulty of operation for the user. Through the cooperation of the locking clip 61 and different locking holes, the sofa cushion is stably fixed, preventing the sofa cushion from moving at will, ensuring the safety and reliability of use. The locking clip 61 also automatically snaps into the new locking hole without additional operation to complete the locking. This "lift-adjust-automatic locking" mechanism simplifies the operation steps of sofa cushion adjustment. The sofa cushion can be changed with a simple lifting and pushing operation, improving the user experience.

[0037] Understandably, the application of this hardware rack is not limited to adjusting sofa cushions; it is also suitable for seating areas in other home furnishing products that require similar rotation or angle adjustment functions, such as office chairs, lounge chairs, or massage chairs.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
