Description

Technical Field

[0001] This utility model relates to the field of chair technology, specifically a reclining chair. Background Technology

[0002] The evolution of the common chair: from simple stools (backless), to chairs with short, straight backs, to chairs with long, straight backs, to chairs with reclining backs, to chairs with soft cushions, to various styles of soft sofas, to chairs with lumbar and head support, and finally to ergonomically designed V-back chairs. This evolution has further led to chairs with manually adjustable height or reclining angles, and electrically adjustable chairs. Currently, all common chairs are used in scenarios where the user is seated.

[0003] In modern society, due to the fast pace of life and work, people generally lack exercise, and there are a large number of office workers who sit or stand for long periods of time. This has led to a high incidence of lumbar spondylosis, cervical spondylosis, lower limb discomfort, and piriformis syndrome. At the same time, as society ages, the elderly have relatively monotonous ways of exercising, mainly walking, which has also led to a high incidence of lumbar spondylosis and lower limb diseases in the elderly, seriously affecting their quality of life.

[0004] Explanation of the name:

[0005] Reclining: When the user lies on the chair, the legs are raised high, with the feet and calves at the highest position, followed by the thighs, while the hips, waist, back and shoulders are basically level, and the head is slightly higher than the chest. Utility Model Content

Regarding the dimensions, angles, and parameters of the components, those skilled in the art can determine or replace them according to actual needs or a limited number of experiments.

[0037] like Figures 1 to 3As shown in the embodiment of this utility model, a reclining chair includes a leg support plate 1, a seat plate 2, and a backrest 3 connected in sequence. A seat plate bracket 4 is connected to the back of the seat plate 2, and a backrest bracket 5 is connected to the back of the backrest 3. When the reclining chair is in a sitting position, the back of the seat plate 2 faces the ground, the seat plate bracket 4 can contact the ground, and the seat plate bracket 4 can support the seat plate 2. The backrest 3, seat plate 2, and leg support plate 1 are arranged in sequence from top to bottom. When the reclining chair is in a reclining state, the back of the backrest 3 faces the ground, the backrest bracket 5 can contact the ground, and the backrest bracket 5 can support the backrest 3. The leg support plate 1, seat plate 2, and backrest 3 are arranged in sequence from top to bottom.

[0038] The calf support plate 1 and the seat plate 2 can be directly or indirectly connected, and the seat plate 2 and the backrest 3 can be directly or indirectly connected. When the reclining chair is in a sitting position, it is supported by the seat plate bracket 4, and the center of gravity of the backrest 3, the seat plate 2, and the calf support plate 1 are arranged sequentially from top to bottom. When the reclining chair is in a reclining position, it is supported by the backrest bracket 5, and the center of gravity of the calf support plate 1, the seat plate 2, and the backrest 3 are arranged sequentially from top to bottom.

[0039] As one possible implementation, when the reclining chair is in a sitting position, it is supported only by the seat support 4; or, it is supported by a portion of the backrest support 5 and the seat support 4. When the reclining chair is in a reclined state, it is supported only by the backrest support 5; or, it is supported by a portion of the seat support 4 and the backrest support 5.

[0040] like Figures 1 to 3 As shown, in one possible implementation, the seat support 4 includes a front lower support 41 and a rear lower support 42 disposed between the front and rear. When the reclining chair is in a sitting position, the reclining chair is supported only by the seat support 4, and both the front lower support 41 and the rear lower support 42 are in contact with the ground. When the reclining chair is in a reclining position, both the rear lower support 42 and the backrest support 5 are in contact with the ground, and the rear lower support 42 and the backrest support 5 can jointly support the backrest 3.

[0041] As an alternative implementation, the lower front support 41, the lower leg support plate 1, and the seat plate 2 can be connected and fixed as a whole. The included angle α between the lower leg support plate 1 and the seat plate 2 can be 100° to 120°. For example, the included angle α between the lower leg support plate 1 and the seat plate 2 can be 110°.

[0042] Alternatively, the front lower support 41, the calf support plate 1, and the seat plate 2 can be set independently, or the front lower support 41 and the calf support plate 1 can be connected and fixed as one unit, while the calf support plate 1 and the seat plate 2 can be set independently. A pivot and a first angle adjustment mechanism are provided between the calf support plate 1 and the seat plate 2, and the first angle adjustment mechanism can adjust the included angle α between the calf support plate 1 and the seat plate 2.

[0043] The method by which the pivot and the first angle adjustment mechanism adjust the included angle between the lower leg support plate 1 and the seat plate 2 can adopt existing technology. For example, an existing adjustment mechanism for adjusting the included angle between the seat cushion and the backrest of a car seat can be used.

[0044] like Figures 1 to 3 As shown, in one possible implementation, the rear lower support 42 and the seat plate 2 are connected and fixed as a whole. The rear lower support 42 is inclined relative to the seat plate 2 and also inclined relative to the backrest 3. The angle between the rear lower support 42 and the seat plate 2 is an obtuse angle, and the angle between the rear lower support 42 and the backrest 3 is also an obtuse angle.

[0045] As one possible implementation, when the reclining chair is in a sitting position, the seat 2 is approximately parallel to the ground; when the reclining chair is in a reclining position, the backrest 3 is approximately parallel to the ground. The backrest 3 includes a head support area 31, a back support area 32, and a lumbar support area 33 arranged sequentially. The head support area 31 is equipped with a headrest, and the lumbar support area 33 is equipped with a lumbar support pillow. The lumbar support pillow can improve poor lumbar spine posture and alleviate discomfort in the lower back and hips caused by prolonged standing or sitting.

[0046] As an alternative implementation, the backrest 3 and the seat 2 can be connected and fixed as a whole, and the included angle β between the backrest 3 and the seat 2 can be 100° to 120°. For example, the included angle β between the backrest 3 and the seat 2 can be 110°.

[0047] Alternatively, the backrest 3 and the seat 2 can be set independently of each other, and a pivot and a second angle adjustment mechanism can be provided between the backrest 3 and the seat 2. The second angle adjustment mechanism can adjust the included angle β between the backrest 3 and the seat 2.

[0048] The method by which the pivot and the second angle adjustment mechanism adjust the included angle between the backrest 3 and the seat 2 can adopt existing technology. For example, an existing adjustment mechanism for adjusting the included angle between the seat cushion and the backrest of a car seat can be used.

[0049] As one possible implementation, one end of the backrest bracket 5 is connected to the backrest 3 via a first pivot 51. The backrest bracket 5 can rotate around the first pivot 51, the axis of which extends in the left-right direction. The backrest bracket 5 can be in a folded or unfolded state.

[0050] When the backrest support 5 is folded, the other end of the backrest support 5 is close to the backrest 3, and the backrest support 5 and the backrest 3 are stacked together. When the backrest support 5 is unfolded, the other end of the backrest support 5 is away from the backrest 3, and the backrest support 5 and the backrest 3 form an angle. When the reclining chair is in a sitting position, the backrest support 5 is folded; when the reclining chair is in a reclining position, the backrest support 5 is unfolded.

[0051] like Figures 1 to 4 As shown, in one possible implementation, a bracket locking mechanism 7 is provided on both the left and right sides of the backrest 3. The bracket locking mechanism 7 includes a slide 71, a connecting rod 72, a pin 73, a screw 74, and a first nut 75. The slide 71 is fixed to the left and right sides of the backrest 3 and is parallel to the backrest 3. The slide 71 contains a groove 76. One end of the connecting rod 72 is connected to the backrest bracket 5 through the pin 73. The connecting rod 72 can rotate around the pin 73. The axis of the pin 73 extends in the left and right direction. The other end of the connecting rod 72 is connected to the first nut 75 through the screw 74. The axis of the screw 74 extends in the left and right direction. The screw 74 is threadedly connected to the first nut 75. The first nut 75 is disposed in the groove 76 and cannot rotate relative to the slide 71.

[0052] When screw 74 is tightened, the other end of connecting rod 72 and the first nut 75 can be fixed in a set position on slide 71; when screw 74 is loosened, the other end of connecting rod 72 and the first nut 75 can reciprocate along slide 71. When backrest bracket 5 is in the folded state, screw 74 and first nut 75 are both located at one end of slide groove 76; when backrest bracket 5 is in the unfolded state, screw 74 and first nut 75 are both located at the other end of slide groove 76.

[0053] The advantage of setting up the bracket locking mechanism 7 is that when the backrest bracket 5 is in the folded state, tightening the screw 74 can lock the backrest bracket 5 in the folded state; when the backrest bracket 5 is in the unfolded state, tightening the screw 74 can lock the backrest bracket 5 in the unfolded state; in addition, by adjusting the position of the first nut 75 and cooperating with tightening the screw 74, the angle between the backrest bracket 5 and the backrest 3 can be adjusted, thereby adjusting the angle between the backrest 3 and the ground and the height of the head support area 31 when lying down.

[0054] As an alternative implementation, the reclining chair also includes an armrest support 6, which is located on the left and right sides of the backrest 3. The armrest support 6 is connected to the backrest 3 via a second pivot 61. The armrest support 6 can rotate around the second pivot 61, the axis of which extends in the left and right direction. The included angle γ between the armrest support 6 and the backrest 3 can be adjusted.

[0055] As an alternative implementation, the mechanism for adjusting the angle between the armrest support 6 and the backrest 3 can employ an existing electric rotary drive mechanism. A control button can be provided on the armrest support 6, which can adjust the angle between the armrest support 6 and the backrest 3 by controlling the electric rotary drive mechanism. For example, the electric rotary drive mechanism can be an existing electric rotary drive mechanism that rotates a robotic arm relative to a robotic hand.

[0056] Alternatively, the angle between the armrest support 6 and the backrest 3 can only be adjusted to a few fixed angles (two or three). For example, the angle between the armrest support 6 and the backrest 3 can only be adjusted to two fixed angles. When the reclining chair is in a sitting position, the armrest support 6 is approximately parallel to the seat 2. At this time, the armrest support 6 is in a sitting position. When the reclining chair is in a reclining position, the armrest support 6 is approximately parallel to the backrest 3 (e.g., in the same plane). At this time, the armrest support 6 is in a reclining position.

[0057] like Figure 5 As shown, the armrest support 6 is connected to an armrest locking mechanism 8. The armrest locking mechanism 8 can lock the armrest support 6 after it rotates, that is, the armrest locking mechanism 8 can lock the armrest support 6 in a sitting or reclining position. As an optional implementation, the armrest locking mechanism 8 includes a pin 81, a spring 82, and a second nut 83. The outer peripheral surface of the second rotating shaft 61 is provided with a first insertion hole 62 and a second insertion hole 63. The pin 81 can be inserted into or disengaged from the first insertion hole 62 or the second insertion hole 63. The spring 82 is connected to the pin 81 and the second nut 83, and the spring 82 can reset the pin 81.

[0058] When the pin 81 is engaged with the first socket 62 or the second socket 63, the armrest support 6 cannot rotate around the second pivot 61; when the pin 81 is disengaged from the first socket 62 or the second socket 63, the armrest support 6 can rotate around the second pivot 61. When the armrest support 6 is in a seated position, the pin 81 is engaged with the first socket 62; when the armrest support 6 is in a reclining position, the pin 81 is engaged with the second socket 63.

[0059] As one possible implementation, elbow supports 34 are provided on both the left and right sides of the backrest 3, and the armrest brackets 6 and elbow supports 34 are spaced apart.

[0060] The following describes the working process of the reclining chair.

[0061] The reclining chair can be positioned in a sitting or reclining state as needed. For example... Figures 1 to 3 As shown, when the reclining chair is in a sitting position, the backrest support 5 is folded, the armrest support 6 is in a sitting position, and the seat 2 is roughly parallel to the ground. The user can sit on the reclining chair as a normal chair. When the reclining chair is in a reclining position, the backrest support 5 is unfolded, the armrest support 6 is reclined, and the backrest 3 is roughly parallel to the ground. The user can lie back on the reclining chair. At this time, the user's head and body are in contact with the backrest 3, the user's buttocks and thighs are in contact with the seat 2, and the user's calves are in contact with the calf support plate 1.

[0062] The reclining chair can be selected between a sitting or reclining position as needed. In the reclining position, the user lies back on the chair with their thighs, calves, and feet raised above their torso, thereby improving blood circulation in the lower limbs and relieving discomfort. Additionally, when reclining, the entire back supports the body's weight, while a lumbar support pillow provides lumbar support, alleviating discomfort in the lower back and hips caused by prolonged standing or sitting.

[0063] The above description is merely a specific embodiment of this utility model and should not be construed as limiting the scope of its implementation. Therefore, any substitution of equivalent components or equivalent changes and modifications made within the scope of protection of this utility model should still fall within its coverage. Furthermore, the technical features, technical solutions, and embodiments of this utility model can be freely combined and used.
