[0002] A chair footrest is an auxiliary device used to provide additional foot support, allowing a person to rest their feet more comfortably when lying on a chair. The design of the footrest is usually matched with the overall style and function of the chair, and can provide different heights and tilt angles to suit the needs and preferences of different users.

[0003] In order to prevent the footrest from interfering with the movement of the person when not lying down, the footrest is usually designed to be foldable, so that it can be flipped and folded when not needed and pushed under the seat, and then pulled out from under the seat and flipped for use when needed. However, the existing footrests pay little attention to the convenience of pulling out the footrests, and there is no fixed gripping position on the footrest body, which brings inconvenience to pulling out the footrests. Utility Model Content

[0040] Embodiment 1

[0041] Please refer to Figure 1 and Figure 4 As shown, the present embodiment provides a footrest 2, including a sliding frame rod 11 and a footrest body 12. The sliding frame rod 11 is slidably set under the seat to be pulled out or pushed in from under the seat; the footrest body 12 is limitedly rotatably set at the front end of the sliding frame rod 11 to switch between a first state and a second state. In the first state, the foot support surface 121 of the footrest body 12 faces upward, and in the second state, the foot support surface 121 is flipped downward; the foot support surface 121 is provided with a handle groove 13 on the rotation center side.

[0042] Specifically, the sliding frame rod 11 can be installed under the seat in a forward and backward sliding manner, and the footrest body 12 can be installed at the front end of the sliding frame rod 11 in a flippable and foldable manner. When the footrest 2 is needed, the footrest body 12 can be pulled out by grasping the rotating side of the handle groove 13, and then the footrest body 12 in the second state is flipped over to rotate and limit it to the first state for use. At this time, the footrest surface 121 is upward, and the foot can be placed on the footrest surface 2 to put the body in a comfortable state; when the footrest 2 is not needed, the footrest body 12 is rotated and limited to the second state, at this time, the footrest surface 121 is downward, and then the footrest body 12 is pushed under the seat. In this way, the structural design of the footrest 2 is simple, easy to use and store, and saves placement space. At the same time, the design of the handle groove 13 also provides a force point for the footrest 2 to be easily grasped by hand, so that the user can easily pull the footrest 2 out from under the seat.

[0043] In addition, correspondingly, on one side of the handle groove 13, the rotation center side of the foot support surface 121 is a horizontal column structure with upper and lower protrusions 1231, and the height of the protrusions 1231 is higher than the foot support surface 121. A blocking body is formed on one side of the foot support surface 121. When the user places his feet on the foot support surface 121, because the body leans on the seat, the feet are easy to slide down due to the natural tilt, and the blocking body just provides a fulcrum for the heel to prevent the foot from sliding, so that the user can be more relaxed and comfortable when using the foot rest 2.

[0044] Furthermore, if Figure 2 and Figure 3As shown, the footrest body 12 also includes a rotating shaft seat 14 and a rotating shaft 15. The rotating shaft seat 14 is connected to the front end of the sliding frame rod 11, and the rotating shaft 15 is inserted in the rotating shaft seat 14. The footrest body 12 is provided with a rotating shaft sleeve 123, and the rotating shaft sleeve 123 is rotatably mounted on the rotating shaft 15. Specifically, the footrest body 12 is mounted on the rotating shaft 15 through the rotating shaft sleeve 123, and the rotating shaft 15 is rotated to drive the two sides of the footrest body 12 to flip at the same time, and the rotating shaft 15 is inserted in the rotating shaft seat 14 connected to the sliding frame rod 11, so that the footrest body 12 and the sliding frame rod 11 are rotatably connected.

[0045] Furthermore, the rotating shaft sleeve 123 is provided with a plurality of protrusions 1231 at intervals along the circumferential direction of the inner wall thereof, and the plurality of protrusions 1231 are rotatably plugged into the rotating shaft 15 , thereby maintaining the rotating shaft sleeve 123 and the rotating shaft 15 to rotate synchronously.

[0046] In this example, if Figure 3 As shown, the rotating shaft seat 14 is provided with a first angle limit block 141, and the footrest body 12 is provided with a second angle limit block 124 corresponding to the first angle limit block 141, so as to maintain the first state or the second state after rotation. Specifically, the rotating shaft 15 drives the rotating shaft sleeve 123 to rotate counterclockwise synchronously until one end of the second angle limit block 124 abuts against one end of the first angle limit block 141, and the footrest body 12 is fixed in the first state, and the foot support surface 121 of the footrest body 12 faces upward, so that the footrest 2 can be used; the rotating shaft 15 drives the rotating shaft sleeve 123 to rotate clockwise synchronously until the other end of the second angle limit block 124 abuts against the other end of the first angle limit block 141, and the footrest body 12 is fixed in the second state, and the foot support surface 121 of the footrest body 12 faces downward, so that the footrest 2 can be stored. In addition, in other embodiments, the second angle limit block 124 can also be set on the rotating shaft 15, and can also play the same limiting role.

[0047] Furthermore, if Figure 4 and Figure 5 As shown, the seat also includes a sliding sleeve 16, which is fixed under the seat, and the sliding frame rod 11 is slidably inserted in the sliding sleeve 16, which is convenient for pulling out or pushing in the sliding frame rod 11. A hook 161 is provided on the outer side of the sliding sleeve 16, and a buckle 142 corresponding to the hook 161 is provided on the outer side of the rotating shaft seat 14. When the sliding frame rod 11 is pushed in, the hook 161 is buckled and fixed with the buckle 142 to prevent the sliding frame rod 11 from sliding out at will.

[0048] Furthermore, if Figure 1As shown, a plurality of ventilation holes 1211 are provided on the foot support surface 121, which can prevent the soles of the feet from being hot and sweaty, and can also increase friction to prevent the feet from slipping. An arc block 122 extends outward from the outer edge of the foot support surface 121, and the arc mouth of the arc block 122 is upward to increase the side support and prevent the feet from slipping outward. At the same time, a plurality of damping protrusions 1221 are provided on the arc mouth surface of the arc block 122, which can have a certain massage effect on the feet.

[0049] Embodiment 2

[0050] Please refer to Figure 1 As shown, this embodiment provides a chair, which is applied with the footrest 2 described in the first embodiment. When the user sits down on the chair 1, the user can put his feet on the footrest 2 to put the body in a more comfortable state.

[0051] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
