Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a rotating mechanism for furniture and a sofa. Background Technology

[0002] A sofa typically consists of a backrest and a sofa body. The backrest is attached to the sofa body and provides back support for the user. To meet customer needs, the backrest is designed to rotate, allowing the user to adjust its angle according to whether they are sitting, standing, or lying down.

[0003] However, while existing sofa backrests can rotate, they only have two rotation angles: a starting angle and an ending angle. They cannot stop and lock between these two angles, thus limiting the adjustable angle of the sofa backrest and making it difficult to meet the needs of customers with different angles.

[0050] Please see Figure 1 and Figure 2 As shown, this utility model embodiment provides a rotating mechanism for furniture, which mainly includes three parts: a triggering mechanism 1, a locking mechanism 2, and a transmission mechanism 3.

[0051] The locking mechanism 2 is used to lock the angle of the furniture after it has been rotated; the locking mechanism 2 includes a locking plate 21 and a locking pin 22, and the locking plate 21 is provided with a plurality of locking holes 211 that cooperate with the locking pin 22;

[0052] Triggering mechanism 1 is used to control the separation and locking of the locking pin 22 and the locking hole 211;

[0053] The transmission mechanism 3 is used to transmit the power of the triggering mechanism 1 to the locking pin 22.

[0054] This application provides a rotating mechanism for furniture, applicable to furniture with backrests, armrests, etc., taking a sofa as an example (see...). Figure 9 and Figure 10 The sofa has a backrest 5 and a body 4. Under normal conditions, the locking pin 22 engages with the locking hole 211, the locking plate 21 is fixedly mounted on the body 4, the locking pin 22 is connected to the backrest 5, and the locking pin 22 cannot rotate within the locking hole 211, so the backrest cannot rotate freely.

[0055] When the angle of the sofa backrest 5 needs to be adjusted, press the trigger mechanism 1 by hand. The trigger mechanism 1 drives the locking pin 22 to move through the transmission mechanism 3, so that the locking pin 22 is separated from the locking hole 211, and the locking pin 22 can rotate relative to the locking plate 21. At this time, the sofa backrest 5 can also rotate smoothly.

[0056] During the adjustment of the sofa backrest 5 rotation angle, the hand is pressed on the trigger mechanism 1, and the locking pin 22 remains separated from the locking hole 211, allowing the sofa backrest 5 to rotate freely. When the sofa backrest 5 rotates to the required angle, the trigger mechanism 1 is released, and the locking pin 22 is reinserted into the locking hole 211 corresponding to the current angle of the sofa backrest 5, thus re-locking and positioning the sofa backrest 5.

[0057] The shape of the locking hole 211 is not limited here, and the locking pin 22 is set to a shape corresponding to the locking hole 211. The number of locking holes 211 in this application can be set according to the rotation angle of the sofa backrest 5, so that for every certain angle of rotation of the sofa backrest 5, a corresponding locking hole 211 engages with the locking pin 22. For example, for every 15 degrees or 30 degrees of rotation of the sofa backrest 5, one locking hole 211 engages with the locking pin 22, realizing multi-angle rotation of the sofa backrest 5.

[0058] During operation, simply pressing the trigger mechanism 1 allows for adjustment of the sofa backrest 5 angle, while releasing the trigger mechanism 1 locks the sofa backrest 5 angle. Compared to existing technologies, this is more convenient to use. Furthermore, the sofa backrest 5 can rotate and position at multiple angles, no longer limited to only rotating to the initial and final angles, thus meeting customers' needs for using the sofa backrest 5 at different angles.

[0059] In one embodiment, such as Figure 2 As shown, the transmission mechanism 3 in this embodiment includes a first transmission component 31 and a second transmission component 32;

[0060] One end of the first transmission member 31 is connected to the triggering mechanism 1, and the other end of the first transmission member 31 is connected to the second transmission member 32. The second transmission member 32 is provided with a rotation center O, and the second transmission member 32 rotates around the rotation center O. The locking pin 22 is movably connected to the second transmission member 32.

[0061] The triggering mechanism 1 drives the second transmission component 32 to rotate around the rotation center O via the first transmission component 31, and the second transmission component 32 drives the locking pin 22 to lock and separate from the locking hole 211.

[0062] In this embodiment, the transmission mechanism 3 is composed of a first transmission member 31 and a second transmission member 32. In this embodiment, both the first transmission member 31 and the second transmission member 32 are transmission rods. By pressing the first transmission member 31 through the trigger mechanism 1, the first transmission member 31 drives the second transmission member 32 to rotate. The second transmission member 32 rotates around the rotation center O, and the second transmission member 32 drives the locking pin 22 to move, thereby controlling the locking pin 22 to lock or disengage from the locking hole 211. This transmission structure is simple in structure, easy to install, and reliable in operation.

[0063] In a further embodiment, such as Figure 2 As shown, the locking pin 22 is provided with a transmission groove 221, and the second transmission member 32 passes through the transmission groove 221. The second transmission member 32 drives the locking pin 22 to move through the transmission groove 221. Compared with the connection between the locking pin 22 and the second transmission member 32 by means of bolts or other structures, it not only eliminates the bolt installation step, but also avoids the risk of loosening when using screws. Therefore, compared with other structures such as screws, this application has the advantages of convenient installation, simple and reliable structure, and long service life.

[0064] In a further embodiment, such as Figure 2 As shown, a connecting groove 311 is provided at the end of the first transmission member 31 near the second transmission member 32, and the second transmission member 32 passes through the connecting groove 311. The second transmission member 32 and the first transmission member 31 are connected through the connecting groove 311, eliminating the need for installation using bolts or other structures, and featuring convenient assembly and strong structural stability. In addition, during operation, the first transmission member 31 moves a short distance, and the second transmission member 32 will not detach from the connecting groove 311.

[0065] In this embodiment, the rotation center O and the first transmission member 31 are respectively connected to the two ends of the second transmission member 32, and the locking pin 22 is connected to the second transmission member 32 between the first transmission member 31 and the rotation center O.

[0066] The locking pin 22 is disposed between the first transmission member 31 and the rotation center O. The rotation center O and the first transmission member 31 can fix the locking pin 22 onto the second transmission member 32, preventing the locking pin 22 from disengaging from the second transmission member 32. Furthermore, during operation, the second transmission member 32 rotates around the rotation center O. Both the locking pin 22 and the first transmission member 31 act on the second transmission member 32, forming a lever structure with the second transmission member 32 as the lever and the rotation center O as the fulcrum. The lever arm of the first transmission member 31 is greater than the lever arm of the locking pin 22. Therefore, during operation, it is labor-saving, and the locking pin 22 can be easily disengaged from the locking hole 211 when operated by hand.

[0067] In a further embodiment, such as Figure 3 and Figure 4 As shown, the transmission mechanism 3 further includes a transmission sleeve 33, with a first transmission member 31 passing through the transmission sleeve 33; a mounting bracket 331 is fixedly mounted on the outer wall of the transmission sleeve 33; a fixed rotating shaft 3312 is mounted on the mounting bracket 331. The second transmission member 32 is rotatably connected to the fixed shaft 3312, and the second transmission member 32 rotates around the fixed rotating shaft 3312 as its rotation center O; the locking pin 22 passes through the mounting bracket 331 at its center.

[0068] A side wall groove 332 is also provided on the rotating sleeve rod 33, and the second transmission member 32 passes through the side wall groove 332 and connects with the first transmission member 31.

[0069] Specifically, the triggering mechanism 1 and the locking mechanism 2 are located at both ends of the transmission sleeve 33. The mounting bracket 331, at the end furthest from the transmission sleeve 33, is bent downwards and has a mounting plate 3311. A fixed rotating shaft 3312 is mounted on the mounting plate 3311. The end of the second transmission member 32 furthest from the first transmission member 31 has a rotating hole 321 (e.g., ...). Figure 8 As shown, the rotating hole 321 cooperates with the fixed rotating shaft 3312 to form the rotation center O of the second transmission component 32. The locking plate 21 is disposed above the mounting bracket 331, and a mounting hole 3313 is provided through the mounting bracket 331. After the locking pin 22 passes through the mounting hole 3313, it cooperates with the locking hole 211. The locking pin 22 slides in the mounting hole 3313, and the mounting hole 3313 plays a role in limiting and guiding the locking pin 22.

[0070] The transmission sleeve 33 integrates the locking pin 22, the first transmission component 31, and the second transmission component 32 into a single unit, so that when the transmission sleeve 33 rotates, it can simultaneously drive the first transmission component 31, the second transmission component 32, and the locking pin 22 to rotate.

[0071] In a further embodiment, such as Figure 4 and Figure 5 As shown, a locking sleeve 23 is provided on the locking plate 21, and an installation plate 24 is fixedly provided at one end of the locking sleeve 23 away from the locking plate 21;

[0072] The locking plate 21 has a plurality of connecting rods 25 arranged in the circumferential direction, and the end of the connecting rod 25 is provided with a support plate 26; the transmission sleeve 33 passes through the locking sleeve 23 and abuts against the support plate 26.

[0073] Specifically, in this embodiment, the connecting rod 25 is a bolt, which fixes the locking plate 21 and the support plate 26 together, facilitating the assembly of the entire structure.

[0074] In addition, the mounting plate 24 is provided with several mounting holes to facilitate the fixed connection between the mounting plate 24 and the sofa body 4. At the same time, the support plate 26 provides support for the transmission sleeve 33, so that the transmission sleeve 33 can be supported on the support plate 26.

[0075] In a further embodiment, such as Figure 5 As shown, in order to reduce the friction of the transmission sleeve rod 33 when it rotates, a bearing is also provided on the support plate 26. A support sleeve 261 that cooperates with the bearing is provided inside the bearing. The end of the transmission sleeve rod 33 is sleeved on the outer periphery of the support sleeve 261. The support bolt 262 passes through the side wall of the transmission sleeve rod 33 and the support sleeve 261, so that the support sleeve 261 is fixedly connected to the transmission sleeve rod 33.

[0076] In a further embodiment, such as Figure 4 and Figure 5 As shown, the transmission mechanism 3 also includes an elastic element 34 that pushes the locking pin 22 to maintain a locked state with the locking hole 211.

[0077] The elastic element 34 provides a continuous pushing force to the locking pin 22, ensuring that even after the triggering mechanism 1 loses its force, the locking pin 22 can still be inserted into the locking hole 211 under the action of the elastic element 34, thus securing the sofa backrest. Furthermore, the elastic element 34 maintains the locking engagement between the locking pin 22 and the locking hole 211 during normal use.

[0078] The elastic element 34 can be a torsion spring, tension spring, or other similar structure. In this embodiment, the elastic element 34 is a locking spring 341 sleeved on the locking pin 22. One end of the locking spring 341 abuts against the mounting bracket 331, and the other end abuts against the circumferential boss of the locking pin 22.

[0079] In another embodiment, the transmission mechanism 3 can also be configured as a combination of a pull rope and a pulley. Specifically, one end of the pull rope is connected to the triggering mechanism 1, and the other end of the pull rope is connected to the locking pin 22. The pulley is assembled and configured according to actual needs. The pull rope is pulled by the triggering mechanism 1, and then the locking pin 22 is pulled by the pull rope to realize the separation and engagement between the locking pin 22 and the locking hole 211.

[0080] In one embodiment, such as Figure 5 As shown, a guide portion 223 is provided at one end of the locking pin 22 near the locking plate 21. The guide portion 223 guides the locking pin 22 into the locking hole 211. In this embodiment, the guide portion 223 is configured as a conical structure, and the inclined surface of the outer wall of the guide portion 223 can serve as a guiding structure. During use, the guide portion 223 can slide along the locking hole 211, thereby allowing the locking pin 22 to be inserted into the locking hole 211.

[0081] In addition, the tapered structure can abut against the locking spring 341, and the locking spring 341 pushes the locking pin 22 to engage with the locking hole 211 by acting on the tapered structure.

[0082] In a further embodiment, such as Figure 5 As shown, adjacent locking holes 211 are connected by a connecting groove 212; a guide rod 222 is provided at the end of the locking pin 22; after the locking pin 22 is separated from the locking hole 211, the guide rod 222 moves through the connecting groove 212 to different locking holes 211.

[0083] During the process of adjusting the angle of the sofa backrest, the locking pin 22 separates from the locking hole 211, and the guide rod 222 can move along the connecting groove 212 to enter the locking hole 211 at different positions. After the sofa backrest is adjusted to the correct angle, the guide part 223 of the locking pin 22 can be inserted into the locking hole 211. The guide rod 222 provides a limit for the engagement between the locking pin 22 and the locking hole 211, and can prevent the locking pin 22 from completely disengaging from the locking hole 211.

[0084] In one embodiment, such as Figure 6 and Figure 7 As shown, the triggering mechanism 1 includes a trigger button 11 and a reset spring 12; the trigger button 11 is connected to the transmission mechanism 3, and when the external force is released, the reset spring 12 pushes the reset button 11 to reset.

[0085] Specifically, the trigger button 11 is fixedly connected to the top of the first transmission member 31, and the trigger button 11 is also located on the top of the transmission sleeve 33; a lower support plate 333 is fixedly provided on the inner side wall of the transmission sleeve 33, and an upper support plate 312 is provided in the circumferential direction of the first transmission member 31. The upper support plate 312 is located above the lower support plate 333, and the return spring 12 is sleeved inside the first transmission member 31, with both ends of the return spring 12 abutting against the upper support plate 312 and the lower support plate 333 respectively.

[0086] The reset spring 12 pushes the support plate 312 to move, thereby pushing the first transmission member 31 to reset. The first transmission member 31 drives the trigger button 11 on its top to move upward, so that the trigger button 11 is reset.

[0087] It should be noted that the triggering mechanism 1 can be provided with a separate trigger button 11 as a triggering component, as in this application, or it can be combined with the transmission mechanism 3, for example, combined with the first transmission member 31 in this embodiment. In this case, the triggering mechanism 1 is a surface provided on the first transmission member 31.

[0088] The working principle of the rotating mechanism for furniture provided in this application is as follows: including a normal use state and an angle adjustment state.

[0089] Normal operating state: The locking spring 341 pushes the locking pin 22 to abut against the locking hole 211, and the return spring 12 pushes the support plate 312, causing the trigger button 11 to push upward and remain in a free state. At the same time, under the action of the return spring 12, the first transmission component 31 pushes upward, and the lower part of the first transmission component 31 drives the second transmission component 32 to move upward. The entire structure enables the locking pin 22 to maintain a cooperative state with the locking hole 211. At this time, the locking pin 22 cannot rotate freely, and the sofa backrest 5 is in a locked state.

[0090] Angle adjustment state: When it is necessary to adjust the angle of the sofa back 5, press the trigger button 11 by hand. The trigger button 11 overcomes the force of the reset spring 12, causing the first transmission component 31 to move downward. The first transmission component 31 drives the second transmission component 32 to rotate counterclockwise around the rotation center O. During the rotation of the second transmission component 32, it drives the locking pin 22 to move downward. The locking pin 22 overcomes the force of the locking spring 341, causing the locking pin 22 to separate from the locking hole 211. At this time, rotate the sofa backrest. During the rotation, the sofa backrest drives the locking pin 22, the first transmission component 31, and the second transmission component 32 to rotate simultaneously via the transmission sleeve 33. The end of the transmission sleeve 33 rotates on the support plate 26. When the sofa backrest 5 is adjusted to the desired position, release the trigger button 11. The reset spring 12 pushes the support plate 312, causing the first transmission component 31 to reset. The first transmission component 31 simultaneously drives the second transmission component 32 to reset. The second transmission component 32 drives the locking pin 22 to reset. The locking pin 22 is reinserted into the locking hole 211, and under the action of the locking spring 341, the locking pin 22 also resets.

[0091] In operation, this application only requires pressing the trigger button 11 to adjust the angle of the sofa backrest 5, and releasing the trigger button 11 will lock the angle of the sofa backrest 5. Compared with the prior art, it is more convenient to use. Moreover, the sofa backrest 5 can achieve multiple angles and multiple positions of suspension, no longer limited to only rotating to the initial and final angles, making it more functional and able to meet the customer's needs for using the sofa backrest at different angles.

[0092] In another embodiment, such as Figure 9 and Figure 10 As shown, this application also provides a sofa, including a sofa body 4 and a sofa backrest 5, including the above-mentioned rotating mechanism for furniture;

[0093] The sofa backrest 5 is rotatably connected to the sofa body 4; the locking plate 21 is fixedly connected to the sofa body 4; when the sofa backrest 5 rotates, it drives the locking pin 22 to rotate.

[0094] Specifically, such as Figure 10 As shown, the mounting plate 24 is fixedly mounted on the bottom of the sofa body 4 by bolts. A backrest bracket 51 is provided inside the sofa backrest 5. A backrest pivot 52 is provided on the backrest bracket 51. The backrest pivot 52 is sleeved on the outside of the transmission sleeve rod 33 and is fixedly connected to the transmission sleeve rod 33. The transmission sleeve rod 33 passes through the sofa body 4 and then through the locking sleeve 23 before abutting against the support plate 26.

[0095] In this embodiment, the rotating mechanism for the furniture works in conjunction with the sofa backrest 5 to enable the sofa backrest 5 to hover at multiple angles and positions. During operation, simply pressing the trigger button 11 adjusts the angle of the sofa backrest 5, while releasing the trigger button 11 locks the angle of the sofa backrest 5.

[0096] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
