Description

Technical Field

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

[0002] A lounge chair is a chair we use to enjoy our leisure time. Unlike formal dining or office chairs, it has a touch of personality and provides both visual and physical comfort. Existing lounge chairs offer a variety of functions, including those with adjustable backrests.

[0003] Existing recliners with adjustable backrest angles typically use an angle adjuster to adjust the angle. To maintain the overall stability of the recliner, the angle adjustment range is relatively small. If the adjustment angle is too large, the chair may tip over because the center of gravity shifts backward when a person is lying on the backrest. However, a small angle adjustment range will affect the comfort of the chair when in use. Therefore, we propose a recliner with adjustable backrest angle. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a lounge chair with an adjustable backrest angle. This solves the technical problem that the angle of the existing lounge chair with adjustable backrest angle is often adjusted by an angle adjuster. In order to maintain the overall stability of the lounge chair, the angle adjustment range is small. When the adjustment angle is large, the chair will tip over because the center of gravity is shifted backward when a person lies on the backrest. However, the small angle adjustment range will affect the comfort of the chair when it is in use.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a leisure chair with adjustable backrest angle, including a leisure chair body, a support mechanism provided on the surface of the leisure chair body, and an auxiliary component engaged on the inner side of the bottom of the leisure chair body;

[0006] The chair body includes a seat, a set of armrests symmetrically fixed on both sides of the seat, a support leg fixed at the bottom of the seat, a pivot engaged inside one side of the seat, and a backrest attached to the top of the seat.

[0007] Preferably, the backrest and the seat form a rotating structure via a pivot, and when the pivot is in a vertical state, the backrest and the seat are parallel.

[0008] Preferably, the support mechanism includes limiting plates, a set of limiting plates are symmetrically fixed to the backrest surface, a shaft is engaged between the set of limiting plates, and a support frame is fixed to the surface of the shaft.

[0009] Preferably, the support frame is U-shaped, and the support frame forms a rotating structure with the limiting plate through the shaft.

[0010] Preferably, the auxiliary component includes a slide, which is movably engaged inside the support leg. The upper surface of the slide has several symmetrically arranged limiting grooves. A pull rod is fixedly connected to one side of the slide, and a limiting screw is inserted into the side of the slide away from the pull rod.

[0011] Preferably, the limiting screw passes through one side of the support leg and is screwed into the inside of the carriage, and the support frame is fitted into a set of limiting grooves on the surface of the carriage.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In this utility model, the backrest and the seat can be adjusted within a wide range of angles. After the backrest is rotated to the required angle via a pivot, the support frame is rotated and the bottom of the support frame is inserted into a set of limiting grooves, thereby completing the limiting support for the backrest.

[0014] 2. In this utility model, pulling the pull rod outward causes the slide to move outward. When the side of the slide away from the pull rod reaches below the limiting screw, the limiting screw is screwed to make it lock into the interior of the slide, thereby achieving the limiting and fixing of the slide. At this time, the slide no longer moves back and forth, improving safety and stability. When storing it later, after screwing out the limiting screw, the slide can be directly pushed into the support leg. Attached Figure Description

[0024] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0025] A lounge chair with an adjustable backrest angle, see [link / reference] Figures 1 to 5 The chair includes a lounge chair body 1, a support mechanism 2 on the surface of the lounge chair body 1, and an auxiliary component 3 engaged on the inner bottom side of the lounge chair body 1.

[0026] The main body of the lounge chair 1 includes a seat 101, a set of armrests 102 are symmetrically fixed on both sides of the seat 101, a support leg 103 is fixed at the bottom of the seat 101, a pivot 104 is engaged inside one side of the seat 101, and a backrest 105 is attached to the top of the seat 101. The backrest 105 and the seat 101 form a rotating structure through the pivot 104. When the pivot 104 is in a vertical state, the backrest 105 and the seat 101 are parallel.

[0027] It is worth noting that the support mechanism 2 includes limiting plates 201. A set of limiting plates 201 are symmetrically fixed to the surface of the backrest 105. A shaft 202 is engaged between the limiting plates 201. A support frame 203 is fixed to the surface of the shaft 202. The support frame 203 is U-shaped and forms a rotating structure with the limiting plates 201 through the shaft 202. In this invention, the backrest 105 and the seat 101 can be adjusted within a wide range of angles. After the backrest 105 is rotated to the desired angle via the pivot 104, the support frame 203 is rotated and its bottom is engaged into a set of limiting grooves 302, thereby completing the limiting support of the backrest 105.

[0028] It is worth noting that the auxiliary component 3 includes a slide 301, which is movably engaged inside the support leg 103. Several limiting grooves 302 are symmetrically opened on the upper surface of the slide 301. A pull rod 303 is fixedly connected to one side of the slide 301. A limiting screw 304 is inserted into the side of the slide 301 away from the pull rod 303. The limiting screw 304 passes through one side of the support leg 103 and is screwed into the inside of the slide 301. The support frame 203 is fitted into a set of limiting grooves 302 on the surface of the slide 301. In this invention, pulling the pull rod 303 outward causes the slide 301 to move outward. When the side of the slide 301 away from the pull rod 303 reaches below the limiting screw 304, the limiting screw 304 is screwed on to lock it into the slide 301, thereby limiting and fixing the slide 301. At this time, the slide 301 no longer moves back and forth, improving safety and stability. When storing it later, after screwing out the limiting screw 304, the slide 301 can be directly pushed into the support leg 103.

[0029] Working principle: When the main body of the lounge chair 1 is in use, the pull rod 303 is pulled outward, which drives the slide 301 to move outward. When the side of the slide 301 away from the pull rod 303 reaches below the limiting screw 304, the limiting screw 304 is turned to make it lock into the slide 301, thereby achieving the limiting and fixing of the slide 301. At this time, the slide 301 no longer moves back and forth. Then, the backrest 105 is rotated to the required angle through the pivot 104, and the support frame 203 is rotated and the bottom of the support frame 203 is locked into a set of limiting grooves 302, thereby completing the limiting support of the backrest 105. When storing it, the backrest 105 is rotated to fit against the seat 101, and the support frame 203 is flipped so that the whole is above the seat 101. Then, the limiting screw 304 is turned out, and the slide 301 is pushed directly into the support leg 103.

[0030] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
