Technical Field

[0001] This utility model relates to the field of leisure chair technology, and in particular to a leisure chair with an adjustable backrest angle. Background Technology

[0002] A lounge chair is a type of seating specifically designed for relaxation, rest, and leisure activities. Its overall contour conforms to the curves of the human body, providing excellent support for the waist, back, and arms, and offering a level of comfort, relaxation, and enjoyment that surpasses that of ordinary chairs.

[0003] Most modern lounge chairs have a fixed backrest angle, which cannot be personalized to suit the user's individual sitting posture habits, nor can it meet the user's different needs for back support angle in different leisure scenarios (such as simply relaxing or reading). The fixed backrest angle forces users to adapt to the lounge chair, resulting in insufficient comfort and scenario adaptability, making it difficult to bring users a truly comfortable and personalized leisure experience. Utility Model Content

[0004] In view of this, the present invention provides a lounge chair with an adjustable backrest angle, which can overcome the shortcomings of current lounge chairs that cannot be personalized according to the user's personal sitting habits, forcing the user to adapt to the lounge chair, resulting in insufficient comfort and scene adaptability, and making it difficult to bring users a truly comfortable and personalized leisure experience.

[0005] Technical solution: A lounge chair with an adjustable backrest angle includes a frame, a seat, a backrest, armrests, a connecting plate, and a blocking mechanism. The seat is connected inside the frame, the backrest is hinged inside the frame, armrests are connected to the left and right sides of the top of the frame, a connecting plate is connected between the two armrests, and the blocking mechanism is used to block the backrest.

[0006] Furthermore, the blocking mechanism includes a stop bar, and each armrest has two round holes, in which a stop bar is placed to block the backrest.

[0007] Furthermore, the backrest has grooves that fit the stop bar.

[0008] Furthermore, it also includes spring steel balls, and the stop bar has slots with spring steel balls installed in the round holes. The spring steel balls can be inserted into the slots to lock the stop bar in place.

[0009] Furthermore, it also includes a first cushion, which is attached to the top of the seat.

[0010] Furthermore, it also includes a second soft pad, with the top of each armrest connected to a second soft pad.

[0011] Furthermore, it also includes pads, with pads symmetrically connected to the left and right sides of the bottom of the frame.

[0012] Furthermore, the edges of the round hole are chamfered, and the edges of the stop bar are also chamfered.

[0013] The present invention has the following advantages: the backrest of the present invention can be adjusted between two angles of 105 degrees and 115 degrees. The angle of the backrest can be flexibly adjusted according to the user's sitting posture habits and different needs such as relaxation and reading, so as to improve the comfort and adaptability of use and bring a more pleasant leisure experience to the user.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0022] refer to Figure 1 and Figure 2An adjustable backrest chair includes a frame 1, a seat 2, a backrest 3, armrests 4, a connecting plate 5, and a blocking mechanism. The open aluminum frame 1 combines architectural feel with structural stability. The seat 2 is bolted to the lower part of the frame 1, and the backrest 3 is hinged to the rear part of the frame 1. Both the seat 2 and the backrest 3 are made of HDPE material, which can conform to the human body curve and provide a comfortable sitting experience. The armrests 4 are bolted to the top left and right sides of the frame 1, and the connecting plate 5 is bolted between the two armrests 4 at the rear. The blocking mechanism is used to block the backrest 3.

[0023] refer to Figure 2 The blocking mechanism includes a stop bar 7. The back of the handrail 4 has two round holes 6. The stop bar 7 is placed in the round holes 6. The corners of the round holes 6 are chamfered, and the corners of the stop bar 7 are also chamfered to facilitate the insertion of the stop bar 7 into the round holes 6.

[0024] The stop lever 7 can block the backrest 3, allowing it to maintain its current angle. When the angle of the backrest 3 needs to be adjusted, the stop lever 7 can be removed from the round hole 6. The armrest 4 has two round holes 6, and the backrest 3 can be adjusted between 105 degrees and 115 degrees. The angle of the backrest 3 can be flexibly adjusted according to the user's sitting posture habits and different needs such as relaxation and reading, improving the comfort and adaptability of use, and bringing a more pleasant leisure experience to the user.

[0025] refer to Figure 3 The upper rear side of the back plate 3 has symmetrical grooves 8 on both the left and right sides. The grooves 8 are compatible with the stop bar 7. The grooves 8 can accommodate the stop bar 7, which can increase the contact area between the stop bar 7 and the back plate 3 and improve the stability of the back plate 3.

[0026] refer to Figures 4-6 It also includes a spring steel ball 10. A slot 9 is opened on the right side of the rear side of the stop rod 7. Spring steel balls 10 are installed in the rear side of the round hole 6 on the right side. After the stop rod 7 is inserted into the round hole 6, the spring steel ball 10 will be inserted into the slot 9 to lock the stop rod 7 and prevent the stop rod 7 from sliding out of the round hole 6.

[0027] refer to Figure 1 It also includes a first soft cushion 11 and a second soft cushion 12. The top of the seat 2 is connected to the first soft cushion 11, and the top of the armrest 4 is connected to the second soft cushion 12. The first soft cushion 11 and the second soft cushion 12 can improve the user's comfort.

[0028] refer to Figure 1 It also includes pads 13. Pads 13 are symmetrically connected to the left and right sides of the bottom of the frame 1. Pads 13 can increase friction and prevent the frame 1 from slipping.
