[0002] Chairs are indispensable for outdoor leisure and entertainment or indoor office leisure. As people's living standards continue to improve, people have higher requirements for the comfort and functionality of chairs in their daily home life. At present, chairs on the market usually have the function of adjusting the angle of the chair back, so that users can lie on the chair. However, the user's legs often have nowhere to rest, making it impossible for the user to relax their legs. Therefore, manufacturers usually design a footrest under the chair to facilitate users to stretch their feet and place them flat on the footrest. In the prior art, the footrest is divided into a fixed footrest and a retractable footrest. The retractable footrest is often a pull-out footrest or a flip-up footrest. In this way, when the user does not use the footrest, the footrest can be hidden under the chair.

[0003] Patent application with publication number CN116473378A discloses a bilateral locking system and a seat for adjusting the footrest of a seat, wherein a bilateral locking assembly is arranged in the footrest assembly and the rotating support body, and adjustment buttons are provided on both sides of the footrest, so that the user can adjust the footrest on either side. However, in the application, the adjustment button needs to be pressed hard to move the rotating shaft seat so that the clamping head is separated from the limiting convex ring. Whether it is a unilateral adjustment mode or a bilateral adjustment mode, the adjustment is relatively laborious. In addition, the spring used for resetting in the application is easily over-compressed and stuck or deformed, thereby reducing the service life of the seat. Utility Model Content

[0045] For the sake of clarity, in the present invention, the direction in which the locking member moves closer to the turntable is considered inner, and the opposite direction is considered outer. When the user uses the seat, the side on which the legs are placed is considered front, and the opposite direction is considered rear.

[0046] like Figures 1 to 9 As shown, the utility model discloses a footrest mechanism, comprising:

[0047] Support frame 101;

[0048] The footrest 2 is rotatably mounted on the support frame 101 and has a plurality of rotation gears;

[0049] Two locking members 3, which include a rod body 31 and a block 32 arranged at one end of the rod body 31, the two locking members 3 are arranged at the left and right ends of the support frame 101, one end of the rod body 31 penetrates into the footrest 2, and the block 32 at the end of the rod body 31 can realize the rotation locking of the footrest 2;

[0050] The adjustment component includes a turntable 41, a pull rope 43 and a rotating rod 42 arranged outside the support frame 101. The turntable 41 is connected to the rod bodies 31 of the two locking members 3 through the pull ropes 43. The rotating rod 42 is connected to the turntable 41. Moving the rotating rod 42 can drive the turntable 41 to rotate, thereby driving the rod body 31 to move inward through the pull rope 43 so that the block 32 at the end of the rod body 31 can release the rotation lock of the footrest 2.

[0051] At this time, the pull rope 43 rotates around the turntable 41, thereby driving the block 32 of the locking member 3 to move inward to release the rotation lock of the footrest 2. The footrest 2 is unlocked, and the footrest 2 can be rotated around the support frame 101 to a suitable angle. The rotating rod 42 is released, and the locking member 3 is reset, thereby driving the locking member 3 to move outward to the block 32 to achieve rotation lock of the footrest 2, thereby completing the angle adjustment of the footrest 2.

[0052] The resetting of the locking member 3 may be performed in one or more of the following embodiments:

[0053] In the first embodiment, the pull rope 43 is an elastic rope. The rotating rod 42 is turned to drive the turntable 41 to rotate. The pull rope 43 generates torque after rotating around the turntable 41. After the rotating rod 42 is loosened, the pull rope 43 is reset under the action of the torque, thereby driving the locking member 3 to reset.

[0054] In the second embodiment, a torsion spring for resetting the pull rope 43 is provided on the turntable 41. The turntable 41 is driven by the rotating rod 42 to rotate, and the torsion spring on the turntable 41 rotates to generate torque. After the rotating rod 42 is loosened, the turntable 41 is reset under the action of the torsion spring torsion, thereby driving the pull rope 43 to reset, and then driving the locking member 3 to reset.

[0055] like Figure 3 , Figure 4 and Fig. 9 As shown, two sleeves 6 are fixedly arranged in the support frame 101, and the sleeves 6 are sleeved outside the rod body 31 of the locking member 3, and the rod body 31 can move back and forth along the sleeves 6. In this way, by providing the sleeves 6, the locking member 3 can be prevented from moving radially during the movement.

[0056] In the third embodiment, a stop portion 62 is provided on the side of the sleeve 6 close to the rotating disk 41, and a spring is sleeved on the pull rope 43, and the spring is located between the stop portion 62 and the rod body 31 of the locking member 3. The rotating rod 42 is turned to drive the rotating disk 41 to rotate, and the pull rope 43 drives the locking member 3 to move inward, thereby compressing the spring located between the stop portion 62 and the rod body 31; after the rotating rod 42 is released, the rod body 31 moves outward to reset under the elastic force of the spring, thereby driving the pull rope 43 and the rotating disk 41 to reset. Moreover, when the pull rope 43 pulls the locking member 3 inward until the rod body 31 abuts against the stop portion 62 of the sleeve 6, the rotating rod 42 is turned to the limit of travel, indicating that the ball 33 of the block 32 on the locking member 3 has completely escaped from the gear slot 211, and the footrest 2 has been unlocked.

[0057] In the fourth embodiment, a protrusion 311 is provided on the rod body 31 of the locking member 3, and a spring is sleeved on the rod body 31, and the spring is located between the protrusion 311 of the locking member 3 and the sleeve 6. The rotating rod 42 is turned to drive the rotating disk 41 to rotate, and the pull rope 43 drives the locking member 3 to move inward, so that the spring is deformed; after the rotating rod 42 is released, the rod body 31 moves outward and resets under the elastic force of the spring, thereby driving the pull rope 43 and the rotating disk 41 to reset.

[0058] Generally speaking, the rotating disk 41 is provided with a rope winding groove for limiting the rotation of the pull rope 43 .

[0059] like Figures 1 to 4 and Figure 7 As shown, the footrest mechanism also includes two shaft components 5, which are fixedly mounted on the left and right ends of the support frame 101, respectively. A guide slot 51 is provided on the inner side of the shaft component 5, and the block 32 of the locking member 3 can move inward or outward along the guide slot 51. A rotating hole 21 is provided on the left and right ends of the footrest frame 2, respectively. The left and right ends of the footrest frame 2 are rotatably arranged on the shaft component 5 by rotating the 21, so as to be rotatably connected with the support frame 101. Part of the block 32 extends out of the guide slot 51 and can be inserted into or removed from the gear slot 211 of the footrest frame 2. In this way, the moving direction of the locking member 3 is limited, ensuring that the locking member 3 always moves axially, and preventing the locking member 3 from rotating during the movement.

[0060] In order to prevent the footrest 2 from moving on the shaft component 5 during rotation, a rotation limit block 52 is convexly provided on the outer side surface of the shaft component 5, and a rotation limit groove 22 is respectively provided on the outer side surface of the footrest 2. When the footrest 2 is rotatably installed on the shaft component 5, the rotation limit block 52 of the shaft component 5 is located in the rotation limit groove 22 of the footrest 2 and can rotate along the rotation limit groove 22.

[0061] In the present invention, the rotation gear is a gear slot 211 provided in the rotation hole 21 on the footrest 2 .

[0062] like Figure 4 and Figure 8 As shown, the block 32 is provided with at least one groove 321 and at least one sphere 33, the sphere 33 and the groove 321 are adapted to each other, and part of the sphere 33 is located in the corresponding groove 321; the block 32 at the end of the rod body 31 is inserted into the rotation gear of the footrest 2 through the sphere 33 to achieve rotation locking of the footrest 2.

[0063] In one embodiment, the ball 33 is partially fixed in the corresponding groove 321, but the friction between the ball 33 and the gear slot 211 is sliding friction, and the user experience is average; in another embodiment, the ball 33 is partially set in the corresponding groove 321 and is rollingly connected to the groove 321. In this way, the friction between the locking piece 3 and the gear slot 211 is rolling friction, and the friction is smaller, which prevents the locking piece 3 and the gear slot 211 from getting stuck, and the user can use it more smoothly and with less effort.

[0064] Generally speaking, there are two balls 33 and two grooves 321, which are symmetrically arranged at both ends of the block 32, and the balls 33 are partially arranged in the corresponding grooves 321. The gear slots 211 should also be arranged in pairs on the footrest 2.

[0065] The left and right ends of the support frame 101 are respectively provided with a mounting groove 12, and a through hole 11 is opened on the bottom surface of the mounting groove 12. The rod body 31 of the locking member 3 is inserted into the through hole 11. The depth of the mounting groove 12 is not less than the diameter of the ball 33, so as to ensure that the ball 33 can escape from the gear slot 211. In order to prevent the ball 33 from escaping from the groove 321 of the locking member 3, when the footrest 2 is installed on the support frame 101, the groove wall of the mounting groove 12 is flush with the groove wall of the gear slot 211, so that the ball 33 is always restricted between the groove 321 of the locking member 3 and the groove wall of the gear slot 211 or between the groove 321 of the locking member 3 and the mounting groove 12 of the support frame 101, so that the ball 33 is prevented from locking failure.

[0066] like Figure 3 and Figure 4 As shown, in order to guide the moving direction of the pull rope 43, two pull rope guide seats 7 are fixedly provided in the support frame 101, and the side walls of the two pull rope guide seats 7 are respectively in close contact with the two pull ropes 43, and the two pull rope guide seats 7 are respectively located at the front and rear sides of the pull rope 43. In this way, during the rotation of the pull rope 43, the end of the pull rope 43 connected to the locking member 3 is always in an axial moving state, ensuring that the locking member 3 moves only in the axial direction.

[0067] In the present invention, the support frame 101 is horizontally arranged between the left and right ends of the footrest 2. The support frame 101 is composed of an upper shell 1011 and a lower shell 1012. The through hole 11 and the mounting groove 12 are provided on the upper shell 1011. A guide rod 102 is fixedly arranged at the left and right ends of the support frame 101, and the guide rod 102 is extended backward. The footrest mechanism also includes a fixed seat 1 for connecting with the seat, and two guide rods 102 are slidably arranged on the fixed seat 1. In this way, the support frame 101 is extended and retracted forward and backward under the seat through the guide rod 101, so that the support frame 101 is pulled out from under the seat or stored under the seat.

[0068] In order to prevent the support frame 101 from easily extending out from under the seat when it is stored under the seat, a magnet is provided at the front end of each fixing seat 1, and magnetic attracting parts matching the magnet are provided at the rear of the left and right ends of the support frame 101. In this way, when the support frame 101 moves backward and is stored under the seat, the support frame 101 is attracted to the magnet of the fixing seat 1 through the magnetic attracting parts.

[0069] The footrest 2 may not be covered with any material, or may be covered with soft materials such as bandages, mesh, etc. to improve the comfort of the footrest 2.

[0070] The utility model also discloses a seat, comprising the footrest mechanism as described above.

[0071] All features described in the specification, the attached claims and the drawings, whether alone or in any combination thereof, are important features of the present utility model.

[0072] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "an implementation", "specific implementation", "other implementations", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment, implementation or example of the utility model.

The technical solution recorded in the utility model also includes a technical solution formed by any one or more of the specific features, structures, materials or characteristics described above in a separate or combined manner.

[0073] Although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limiting the utility model. Ordinary technicians in the field can change, modify, replace, modify, delete some features, add features or re-combine features to form a technical solution in the above embodiments without departing from the principles and purpose of the utility model within the scope of the utility model.
