[0026] Hereinafter, embodiments will be illustrated in conjunction with the accompanying drawings. Furthermore, the embodiments illustrated hereinafter do not limit the content of the present application defined by the claims. Also, all content illustrated by the embodiments below are not limited to necessary content for technical solutions of the present application defined by the claims.

[0027] The present application provides a folding reclining chair so as to realize an object of improving resting quality.

[0028] As shown in Figures 1 to 5, the folding reclining chair includes a backrest frame 1, a seat frame 2, a rear foot frame 4, a front foot frame 3 and an armrest tube 5. The backrest frame 1 is articulated to an end of the seat frame 2, and an end of the front foot frame 3 is articulated to the armrest tube 5. A middle portion of the front foot frame is articulated with two sides of the seat frame 2. A chair top 7 is provided on the backrest frame 1 and the seat frame 2. A middle portion of the rear foot frame 4 is articulated with the backrest frame 1, the rear foot frame 4 is articulated with the front foot frame 3, and the front foot frame 3 is articulated to the armrest tube 5 via a slide block 6. The slide block 6 is slidably arranged on the armrest tube 5, and is provided with a locking mechanism 9 for locking the sliding block 6 onto the armrest tube 5.

[0029] When using the folding reclining chair as a chair, the sliding block 6 is slid to a proper position, the backrest frame 1 is adjusted to be substantially perpendicular to the seat frame 2, and then the sliding block 6 is fixed onto the armrest tube 5 via the locking mechanism 9, thus at this time the folding reclining chair may be used as a chair. When using the folding reclining chair as a reclining chair, the locking mechanism 9 is released, and the sliding block 6 is slid further to adjust an angle between the backrest frame 1 and the seat frame 2, and then the sliding block 6 is fixed onto the armrest tube 5 via the locking mechanism 9, thus at this time the folding reclining chair may be used as a reclining chair. The locking mechanism 9 is released, the sliding block 6 is slid further, the backrest frame 1 and the seat frame 2 are adjusted to be substantially parallel to each other, and then the sliding block 6 is fixed onto the armrest tube 5 via the locking mechanism 9, thus at this time the folding reclining chair may be used as a bed. In the above folding reclining chair, the angle between the backrest frame 1 and the seat frame 2 can be adjusted via the sliding block 6 and the locking mechanism 9, which may allow a user to be in a best resting position to the greatest extent, thereby improving the resting quality.

[0030] According to the folding reclining chair in an embodiment of the present application, the locking mechanism 9 may be a conventional locking mechanism 9, and when the sliding block 6 slides to a predetermined position, the locking mechanism 9 may realize the function of fixing the sliding block 6 at that position.

[0031] For example, the sliding block 6 slides on the armrest tube 5 via a guide rod provided with multiple locking positions, and the sliding block 6 is provided with multiple locking hooks. When the sliding block 6 slides to a preset position, the locking hook of the sliding block 6 is hooked on the locking position. For ensuring the stability, there are at least two locking hooks, one of the locking hooks is connected with a locking position at one side of the sliding block 6, and the other locking hook is connected with a locking position at the other side of the sliding block 6, thereby realizing the object of locking the sliding block 6.

[0032] Or, the sliding block 6 is disposed on a rack 91. Specifically, two ends of the rack 91 are fixed at two ends of the armrest tube 5 respectively. The sliding block 6 is provided with a sawtooth structure at a sidewall corresponding to teeth of the rack 91, and a strip-type hole is provided at both two sides of the sawtooth structure. A connecting hoop is disposed at an outside of the sliding block 6, and a screwing button having an irregular shape is articulated to two ends of the connecting hoop. During rotating process of the screwing button, a side surface relatively far from an axis of the screwing button press down the sidewall of the sliding block 6 having the sawteeth, such that the sawteeth on the sidewall engages with the sawteeth on the rack 91, thereby realizing the locking function. When it is needed to slide the sliding block 6 again, the screwing button is rotated, a side surface of the screwing button relatively close to the axis of the screwing button is in contact with the sliding block 6, such that the sidewall of the sliding block 6 having the sawteeth returns to an original state under the action of the elastic force itself, and the sawteeth on the sliding block 6 are disengaged from the sawteeth on the rack 91, thereby ensuring that the sliding block 6 is slidable on the rack 91.

[0033] In addition, the above locking mechanism 9 includes the rack 91 and a locking screwing block 92. Specifically, two ends of the rack 91 are fixed to two ends of the armrest tube 5 respectively. The sliding block 6 is disposed on the rack 91, and is slidable on the rack 91. The locking screwing block 92 is articulated to the sliding block 6, and has sawteeth which can be rotated to engage with the rack 91. For facilitating rotating the locking screwing block 92, the locking screwing block 92 is provided with a handle 93. When the sliding block 6 reaches a preset position, the locking screwing block 92 is rotated to enable the sawteeth on the locking screwing block 92 to engage with the sawteeth on the rack 91, thereby realizing the object of locking the sliding block 6. When it is needed to slide the sliding block 6 again, the locking screwing block 92 is rotated in a reverse direction so as to disengage the sawteeth on the locking screwing block 92 from the sawteeth on the rack 91, such that the sliding block 6 is in a free state, and is slidable on the rack 91.

[0034] For further optimizing the above technical solutions, a spring is further provided between the sliding block 6 and the armrest according to an embodiment of the present application, such that the backrest frame 1 may be prevented from being laid down too rapidly. Specifically, for the above locking mechanisms 9, in the first type of the locking mechanisms 9, the spring is sleeved on the guide rod and is away from the backrest frame 1; in the second and third types of the locking mechanisms 9, the spring is sleeved on the rack 91 and is away from the backrest frame 1.

[0035] The seat frame 2 according to an embodiment of the present application includes a frame of the chair top 7 and a foot rest frame 22. A middle portion of the frame of the chair top 7 is articulated to a middle portion of the front foot frame 3, one end of the frame of the chair top 7 is articulated to the backrest frame 1, and the other end of the frame of the chair top 7 is articulated to the foot rest frame 22. During using, the foot rest frame 22 may be stretched out. For example, a supporting rod is provided on two side rods of one of the foot rest frame 22 and the front foot frame 3, and a free end of the supporting rod is provided with a locking opening, two side rods of the other one of the foot rest frame 22 and the front foot frame 3 is provided with a locating column. When the foot rest frame 22 is required to be stretched out, the locking opening of the supporting rod is retained on the locating column, thereby realizing the object of stretching out the foot rest frame 22.

[0036] Since the above technical solution requires a second manual operation, thus is relatively complicated. An embodiment of the present application further provides another solution, that is, a connecting rod 8 is provided between a bottom end of the backrest frame 1 and the foot rest frame 22. One end of the connecting rod 8 is articulated to the bottom end of the backrest frame 1, and the other end of the connecting rod 8 is articulated to a middle portion of the foot rest frame 22. When the backrest frame 1 is stretched out, the backrest frame 1 may push the connecting rod 8 to support the foot rest frame 22, such that the foot rest frame 22 is stretched out.
