Detailed Description

In order to make the present utility model better understood by those skilled in the art, the following description of the technical solutions of the present utility model will be made in detail, but not all embodiments of the present utility model are apparent to some embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.

As shown in fig. 1 to 10, a folding chair includes a seat portion 1, a backrest portion 2 disposed at an angle to the seat portion 1, and a movable mechanism 3. The movable mechanism 3 comprises a folding unit 4, a rotating unit 5 connected to the folding unit 4, and a pillow part 6 connected to the rotating unit 5.

The folding and unfolding unit 4 is provided corresponding to the cushion portion 1, and may be protruded with respect to the cushion portion 1, or may be folded up and down to be overlapped with the cushion portion 1. The rotating unit 5 can rotate to different angles relative to the folding unit 4. The folding unit 4 and the rotating unit 5 have at least three use states, as shown in fig. 2, and are in a first use state at this time, in this first use state, the folding unit 4 is pulled out from under the cushion portion 1, and the folding unit 4, the rotating unit 5 and the pillow portion 6 are in the same plane, and the plane is parallel to the cushion portion 1, so that when a person uses the folding chair, the legs of the person can be stretched and then rest on the pillow portion 6, i.e., the pillow portion 6 plays a leg rest function.

As shown in fig. 6, the folding unit 4 and the rotating unit 5 are in the second use state, in which the folding unit 4 is partially rotated above the cushion portion 1, and the folding unit 4 and the rotating unit 5 form an angle that is consistent with the angle between the cushion portion 1 and the backrest portion 2, so that the pillow portion 6 is attached to the backrest portion 2, that is, the pillow portion 6 functions as a lumbar support.

As shown in fig. 9, the folding unit 4 and the rotating unit 5 are in the third use state, in which the pillow 6 is neither used as a lumbar nor as a leg rest, the folding unit 4 is folded under the cushion 1, and the folding unit 4 and the rotating unit 5 form an included angle, and the included angle therebetween is almost zero, that is, the rotating unit 5 is folded under the folding unit 4 while the folding unit 4 is folded under the cushion 1, so that the pillow 6 is stored under the cushion 1.

In the present embodiment, the retracting unit 4 is located below the cushion portion 1, which is a telescopic rod mechanism located at both sides of the cushion portion 1, however, in other embodiments, the retracting unit 4 may be located above the cushion portion 1, which is not limited specifically.

In order to realize the extension and retraction of the retracting unit 4, sleeves 11 for at least part of the retracting unit 4 to movably extend into are arranged on two sides of the bottom of the cushion part 1, in other words, the sleeves 11 are fixedly connected with the cushion part 1, which plays the role of supporting the retracting unit 4 and also prevents the retracting unit 4 from being separated from the cushion part 1.

As shown in fig. 2 and 3, taking the single-sided structure of the folding and unfolding unit 4 as an example, the folding and unfolding unit 4 includes an adapter 41, a main body portion 42 and a telescopic portion 43 respectively connected to two ends of the adapter 41, the rotating unit 5 is connected to the telescopic portion 43, and the telescopic portion 43 can rotate to the upper side of the cushion portion 1 relative to the adapter 41, so that the pillow portion 6 is attached to the backrest portion 2.

Specifically, the adapter 41 is of a flat rod structure, one end of the main body portion 42 connected with the adapter 41 is provided with a first limiting clamping groove 421, the first limiting clamping groove 421 is provided with a top opening 422 and a side opening 423, the adapter 41 is rotationally connected to the first limiting clamping groove 421 through a rotating shaft, the adapter 41 can rotate to be in the same straight line with the main body portion 42 through the side opening 423, and can rotate to be perpendicular to the main body portion 42 through the top opening 422. The bottom of the first limiting slot 421 opposite to the top opening 422 is a closed structure, which is used for supporting the adapter 41, and also preventing the adapter 41 from rotating downward, thereby realizing unidirectional rotation of the adapter 41.

As shown in fig. 2, the telescopic portion 43 includes at least a first telescopic rod 431 and a second telescopic rod 432 which are provided inside and outside, and the telescopic operation of the first telescopic rod 431 and the second telescopic rod 432 can adjust the overall length of the telescopic portion 43, so that the telescopic portion can be adapted to users with different leg lengths in a first use state, and can be adapted to cushion portions 1 with different lengths in a second use state. The second telescopic rod 432 has a second limit catch 433 for unidirectional rotation of the connection adapter 41. In other words, the structure of the second limiting slot 433 is similar to that of the first limiting slot 421, and the second telescopic rod 432 can rotate to be perpendicular to the adapter 41 through the top opening and to be in the same line with the adapter 41 through the side opening, and the second telescopic rod 432 cannot rotate downward relative to the adapter 41.

Therefore, when the folding and unfolding unit 4 is switched from the first use state to the second use state, the adapter 41 rotates upwards relative to the main body 42, and the second telescopic rod 432 rotates to the upper side of the cushion portion 1 relative to the adapter 41, and the folding and unfolding unit 4 is located on two sides of the cushion portion 1, so that normal use of the cushion portion 1 is not affected.

In order to rotate the rotating unit 5 to different angles relative to the folding unit 4, as shown in fig. 9, the rotating unit 5 includes a first engaging tooth 51, a first telescopic rod 431 of the telescopic part 43 includes a second engaging tooth 52, and a locking member 53 may sequentially pass through the centers of the first engaging tooth 51 and the second engaging tooth 52, so as to achieve engagement or release of the first engaging tooth 51 and the second engaging tooth 52. Specifically, the lock member 53 is released, and the first engagement tooth portion 51 and the second engagement tooth portion 52 are adjusted to a target angle with respect to the rotation unit 5 after releasing the telescopic portion 43, and the first engagement tooth portion 51 and the second engagement tooth portion 52 are engaged by the lock member 53 so as to be maintained at the target angle. Since the first and second engagement teeth 51 and 52 extend nearly one turn in the circumferential direction, the angular adjustment range of the retracting unit 4 and the rotating unit 5 is wide.

To further enhance comfort, the pillow 6 has an arcuate surface 61 that better fits the waist or legs of the person. Of course, the angle between the pillow part 6 and the rotation unit 5 can also be adjusted, which is the prior art and will not be described again.

The headrest portion 21 is rotatably connected to the top of the backrest portion 2, and the headrest portion 21 can be rotated to the rear side of the backrest portion 2 to be folded and stored, so that the use is flexible.

The foregoing detailed description is provided to illustrate the present utility model and not to limit the utility model, and any modifications and changes made to the present utility model within the spirit of the present utility model and the scope of the appended claims fall within the scope of the present utility model.
