[0031] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] like Figures 1 to 4 As shown, the embodiment of the present application provides a zero-gravity lunch break chair with waist support, including a seat cushion assembly 10, a backrest assembly 20 and a waist support 30. The seat cushion assembly 10 is used to provide support for people to sit, the backrest assembly 20 is used to provide support for the back when people sit down, and the waist support 30 is used to provide support for the waist when people sit down to make people more comfortable when sitting. The waist support 30 is connected to the seat cushion assembly 10, and the seat cushion assembly 10 is connected to the backrest assembly 20 and has a locked state and an unlocked state. The seat cushion assembly 10 can switch between the locked state and the unlocked state.
[0033] It should be understood that in the locked state, the seat cushion assembly 10 and the backrest assembly 20 are fixed in position. In this case, when a person sits on the nap chair, the back can stand upright, and the lumbar support 30 is at the rear of the backrest assembly 20. In the unlocked state, the seat cushion assembly 10 slides relative to the backrest assembly 20 so that the lumbar support 30 can move from the rear of the backrest assembly 20 to the front of the backrest assembly 20, that is, the nap chair is in a state where a person can lie down. When the seat cushion assembly 10 slides to a preset position, the seat cushion assembly 10 can rotate relative to the backrest assembly 20. In this way, by setting the seat cushion assembly 10 to be connected to the backrest assembly 20 and having a locked state and an unlocked state, the nap chair can allow a person to sit or lie down, and by setting the seat cushion assembly 10 to rotate relative to the backrest assembly 20 to drive the lumbar support 30 to support the waist of the person, the waist of the person lying on the nap chair can be supported by the lumbar support 30, which increases the comfort of the person after lying down. It should be understood that when the nap chair in the present application is in an unlocked state, a person lying on the nap chair is in a zero gravity state, which can also greatly increase the comfort of the nap chair.
[0034] The nap chair in the present application can smoothly switch states without moving or swinging the table, making nap convenient.
[0035] In one embodiment, the seat cushion assembly 10 includes a seat cushion 11 and a seat cushion bracket 12, and the seat cushion 11 is arranged on the seat cushion bracket 12. The backrest assembly 20 includes a backrest 21 and a backrest bracket 22, and the backrest 21 is arranged on the backrest bracket 22. A hollow portion is formed between the backrest 21 and the seat cushion 11, and an arc-shaped guide groove 23 is arranged on the backrest bracket 22. A first bayonet 24 is arranged at the end of the arc-shaped guide groove 23. A boss (not shown in the figure) is arranged on the seat cushion bracket 12, and the boss can also be connected to the backrest bracket 22 by passing through the seat cushion bracket 12 with a bolt. The boss is inserted into the arc-shaped guide groove 23, and the boss can slide in the arc-shaped guide groove 23. When the boss slides to the first bayonet 24, the first bayonet 24 restricts the movement of the boss, and the seat cushion bracket 12 and the backrest bracket 22 are limited to each other, that is, they are in a locked state at this time. When the nap chair is switched from a locked state to an unlocked state, a manual force is applied to disengage the boss from the first bayonet 24 and enter the arc-shaped guide groove 23. The arc-shaped structure facilitates the boss to slide in the arc-shaped guide groove 23. At this time, the backrest assembly 20 can be rotated downward, and the person on the nap chair can change from a sitting position to a lying position.
[0036] Specifically, the first bayonet 24 is connected to the arc-shaped guide groove 23 to form a hook shape. The first bayonet 24 is connected to the arc-shaped guide groove 23 to facilitate the sliding of the protruding column to achieve the state switching of the lunch break chair.
[0037] In one embodiment, the backrest bracket 22 includes a first frame 221, a second frame 222 and a connecting seat 223. The first frame 221 and the second frame 222 are arranged at an angle. The second frame 222 is rotatably connected to the first frame 221 through the connecting seat 223. The position of the first frame 221 is fixed, that is, the first frame 221 is arranged horizontally in the horizontal direction, and the second frame 222 can be tilted relative to the first frame 221.
[0038] In order to enable the buttocks and waist of a person to respectively drive the seat cushion bracket 12 and the backrest bracket 22 to rotate when the person lies down so that the lumbar support 30 supports the person's waist, a connecting rod 121 is provided at one end of the seat cushion bracket 12 away from the boss, and the connecting rod 121 is rotatably connected to the first frame 221, that is, the seat cushion bracket 12 rotates relative to the first frame 221.
[0039] In order to ensure the overall structural stability, in the present application, two seat cushion brackets 12 and two backrest brackets 22 are provided and are spaced apart from each other.
[0040] In one embodiment, the nap chair further includes a leg rest assembly 40, which is used to support the calf of a person to relax the calf, and the leg rest assembly 40 is arranged on the seat cushion assembly 10 and its position on the seat cushion assembly 10 is adjustable. It should be understood that the leg rest assembly 40 here can change the position of the leg rest assembly 40 relative to the seat cushion assembly 10 according to the support needs of different people, that is, it can be adjusted according to the height of the human body.
[0041] Furthermore, the leg rest assembly 40 includes a leg rest 41, a leg rest bracket 42 and an adjustment seat 43. The leg rest 41 is connected to the leg rest bracket 42. The adjustment seat 43 is arranged at the bottom of the seat. The leg rest bracket 42 is provided with a clamping column 421. The bottom of the adjustment seat 43 is provided with a plurality of clamping slots 431. The position of the leg rest assembly 40 can be adjusted by changing the installation position of the clamping column 421 in different clamping slots 431.
[0042] Specifically, in order to ensure the stability of the movement of the leg rest assembly 40, a telescopic structure 50 is provided between the leg rest bracket 42 and the seat cushion bracket 12. The telescopic structure 50 includes a guide rod 51 and a guide column 52, the guide column 52 is hollow inside, the guide column 52 is provided on the seat cushion bracket 12, and the guide rod 51 is provided inside the guide column 52.
[0043] In the present application, the nap chair further includes a leg 60, and the seat cushion assembly 10 and the backrest assembly 20 are both arranged on the leg 60. Two legs 60 are arranged and the legs 60 are arranged to be able to adjust the height to meet the needs of people of different heights. That is, the height of the seat cushion 11 can also be adjusted according to the height of the person, and accordingly, when the lumbar support 30 is installed, it is also arranged to meet the needs of people of different heights.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
