Description

Technical Field

[0001] This utility model relates to health care equipment, and in particular to a health care chair with a movable seat that allows leg movement while seated. Background Technology

[0002] The earliest stools, benches, and chairs used by humans all evolved from stools. After the invention of chairs, people continuously improved them to enhance comfort and practicality, resulting in various multifunctional chairs. Following industrial reforms, electric mechanical medical chairs and massage chairs emerged, further improving the functionality, durability, and operability of chairs. However, neither chairs nor stools have solved the problem of slowed blood flow and poor circulation caused by prolonged sitting. According to the Life Times, the latest research has found that sitting in front of a computer for extended periods increases the risk of deep vein thrombosis (DVT). Studies show that sitting continuously for more than 90 minutes reduces blood flow to the knees by 50%, and sitting motionless for more than 4 hours further increases the risk of DVT. Furthermore, existing electric mechanical medical chairs and massage chairs are complex in structure, have high manufacturing costs, and consume a lot of energy; their development is almost entirely based on a process of upgrading from simple to complex, hindering their widespread adoption. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to provide a health chair with a movable seat that allows leg movement in a sitting position, so as to solve the technical problems of slowed blood flow and poor meridian circulation caused by prolonged sitting in existing chairs and stools.

A drive mechanism is connected to the left and right seat panels respectively, which enables one of the two buttocks to sit on the left or right seat panel while the other buttocks are suspended.

[0006] Furthermore, the drive mechanism drives the left and right seat panels to move up and down or to reciprocate around the hinge point.

[0007] Furthermore, the drive mechanism is a telescopic rod, which also includes a support base located below the seat surface. The telescopic rod connects the support base to the left seat panel and the right seat panel to realize the up and down movement of the left seat panel and the right seat panel.

[0008] Furthermore, it also includes a frame located outside the seat surface, with the left and right seat panels movably connected to the frame via hinge shafts on opposite sides, and the drive mechanism driving the left and right seat panels to reciprocate around the hinge shafts.

[0009] Furthermore, it also includes a central hinge shaft located in the middle of the seat surface, with the adjacent sides of the left and right seat panels hinged to the central hinge shaft, and the drive mechanism driving the left and right seat panels to reciprocate around the central hinge shaft respectively.

[0010] Furthermore, an elastic seat cushion is provided on the seat surface to prevent the buttocks from being pinched.

[0011] Furthermore, the driving mechanism is a telescopic mechanism or a rotating mechanism.

[0012] Furthermore, it also includes chair legs and support members, with the upper ends of the two telescopic mechanisms movably connected to the left and right seat panels respectively, and the lower ends movably connected to the support members respectively.

[0013] Furthermore, the lower end of the chair leg is provided with a height adjustment device.

[0014] Furthermore, a control unit is provided on the drive mechanism, and the control unit includes frequency and time.

[0015] The beneficial effects of this utility model are:

[0016] This utility model discloses a health chair with a movable seat that enables leg movement while seated. Driven by a mechanism, the user's buttocks can rest entirely on the seat, with the left leg resting on the left seat panel and the right leg suspended, or vice versa. This allows for relaxation when the legs are suspended, and these three methods can be alternated, enabling a walking-like movement pattern while seated. This provides exercise for those who sit for long periods, completely solving the technical problems of poor blood circulation and blocked meridians after prolonged sitting. It also massages and exercises the tendons around the pelvis and lumbar vertebrae.

[0017] The drive mechanism is set as a telescopic rod to enable the left and right seat panels to move vertically up and down.

[0018] The left and right seat panels are connected to the frame via hinge shafts, and the left and right seat panels rotate up and down around the hinge shafts under the action of the drive mechanism.

[0019] The height of the health chair can be easily adjusted by installing a height adjustment device at the bottom of the chair legs.

The upper ends of the two telescopic rods 8 are respectively fixedly connected to the left seat panel 22 and the right seat panel 23. Figure 3 As shown, when the left telescopic rod 8 remains stationary and the right telescopic rod 8 retracts, it moves the right seat panel 23 downwards, allowing the left hip to sit on the left seat panel 22 while the right hip is suspended in the air; conversely, as... Figure 4 As shown, when the right telescopic rod 8 remains stationary, the left telescopic rod 8 retracts, causing the left seat panel 22 to move downwards, so that the right lobe of the buttocks sits on the seat surface while the left lobe of the buttocks is suspended in the air. This alternation achieves relaxation of the suspended buttocks. This method is the most energy-efficient because the telescopic rod 8 operates without load. Alternatively, the left telescopic rod 8 can remain stationary while the right telescopic rod 8 extends, causing the right seat panel 23 to move upwards, so that the right lobe of the buttocks sits on the right seat panel 23 while the left lobe of the buttocks is suspended in the air. When the right telescopic rod 8 remains stationary while the left telescopic rod 8 extends, causing the left seat panel 22 to move upwards, so that the left lobe of the buttocks sits on the left seat panel while the right lobe of the buttocks is suspended in the air. This alternation achieves relaxation of the suspended buttocks. This embodiment solves the technical problem of poor blood circulation and meridian blockage caused by prolonged sitting, and plays a role in massage, health care and exercise. The distance that the seat surface 2 moves up and down is 2-5cm, and an elastic seat cushion to prevent buttock pinching is placed on the seat surface.

The movement of the left seat panel 22 and the right seat panel 23 alternates. The two telescopic mechanisms 3 do not intersect. The telescopic mechanism 3 can be an electric telescopic mechanism, a hydraulic rod, or a pneumatic rod, etc. Alternatively, the hinge shaft 5 between the left seat panel 22 and the right seat panel 23 and the frame 21 is directly connected to a rotating mechanism. The rotating mechanism drives the hinge shaft 5 to rotate the left seat panel 22 or the right seat panel 23 up and down. A backrest 6 is located on the rear side of the seat surface 2, and armrests 7 are located on both sides. Figure 8 As shown, when the left telescopic mechanism 3 remains stationary, the right telescopic mechanism 3 retracts, causing the right seat panel 23 to flip downwards. At this time, the left hip sits on the left seat panel 22, while the right hip is suspended in the air; conversely, as... Figure 9 As shown, the right telescopic mechanism 3 remains stationary, while the left telescopic mechanism 3 retracts, causing the left seat panel 22 to flip downwards. At this time, the right hip lobe sits on the right seat panel 23, while the left hip lobe is suspended in the air. This method is the most energy-efficient because the telescopic mechanism 3 operates without load. Alternatively, the left telescopic mechanism 3 can remain stationary, while the right telescopic mechanism 3 extends, causing the right seat panel 23 to flip upwards. In this case, the left hip lobe is suspended in the air, and the right hip lobe sits on the right seat panel 23. Conversely, the right telescopic mechanism 3 remains stationary, while the left telescopic mechanism 3 extends, causing the left seat panel 22 to flip downwards. 2. Flip upwards, at which point the left hip sits on the left seat panel 22, while the right hip is suspended in the air; this alternation solves the technical problem of poor blood circulation and meridian blockage caused by prolonged sitting, and plays a role in massage, health care and exercise. All the above-mentioned hinge shafts are parallel, the two telescopic mechanisms 3 are electrically connected to the control unit, the control unit is connected to the buttons, and the buttons are set on the armrests 7 of the health chair. The operating parameters of the two telescopic mechanisms 3 of the health chair, such as the operating frequency and duration of the telescopic mechanism, are set through the buttons. The distance that the seat surface 2 moves up and down is 2-5cm, and an elastic cushion to prevent the buttocks from being pinched is placed on the seat surface 2.

[0041] As mentioned above, the lower end of the chair leg 1 is provided with a height adjustment device to facilitate the adjustment of the chair height.

The locking pin 13 passes through the positioning holes on the outer tube 11 and any positioning hole on the inner rod 12 to achieve height adjustment and locking.

[0042] Example 3

[0043] like Figure 10-13 As shown, a health chair with a movable seat surface that allows leg movement in a seated position includes four chair legs 1 supporting a seat surface 2. A support member 4 is located between the four chair legs 1 under the seat surface 2. Preferably, the support member 4 consists of two support rods 41 and a crossbeam 42. The two support rods 41 are respectively connected between the two left chair legs 1 and the two right chair legs 1, and the crossbeam 42 connects the two support rods 41. The seat surface 2 consists of a frame 21 and a support frame 21 that contacts the two buttocks respectively. The seat surface consists of a left seat panel 22 and a right seat panel 23. The seat surface also includes a central hinge shaft 9 located on the transverse centerline of the seat surface 2. The adjacent sides of the left seat panel 22 and the right seat panel 23 are hinged to the central hinge shaft 9. Below the opposite sides of the left seat panel 22 and the right seat panel 23, telescopic mechanisms 3 are hinged to each other via hinge shafts. The lower ends of the two telescopic mechanisms 3 are respectively hinged to a crossbeam 42 via hinge shafts. All the aforementioned hinge shafts are parallel to the central hinge shaft 9. A backrest 6 is provided on the rear side of the seat surface 2, and armrests 7 are provided on both sides. Figure 12 As shown, when the left telescopic mechanism 3 remains stationary, the right telescopic mechanism 3 retracts, causing the right seat panel 23 to flip downwards. At this time, the left hip sits on the left seat panel 22, while the right hip is suspended in the air; conversely, as... Figure 13 As shown, when the right telescopic mechanism 3 remains stationary and the left telescopic mechanism 3 retracts, it causes the left seat panel 22 to flip downwards. At this time, the right hip lobe sits on the right seat panel 23, while the left hip lobe is suspended. This alternation achieves relaxation of the suspended hip lobe. Since the telescopic mechanism 3 operates without load, this method is the most energy-efficient. Alternatively, the left telescopic mechanism 3 can remain stationary while the right telescopic mechanism 3 extends, causing the right seat panel 23 to flip upwards. In this case, the left hip lobe is suspended, and the right hip lobe sits on the right seat panel 23. Conversely, the right telescopic mechanism 3 can remain stationary while the left telescopic mechanism 3 extends, causing the left seat panel 22 to flip upwards. In this case, the right hip lobe is suspended, and the left hip lobe sits on the left seat panel 22. An elastic seat cushion that prevents hip pinching is placed on the seat surface 2.

[0044] This health chair with a movable seat that allows leg movement while seated is an inheritance and development of traditional stools and chairs. It breaks through the traditional form of a fixed seat, allowing the buttocks to sit fully on the seat, or the left side to sit on the left seat panel while the right side is suspended, or the right side to sit on the right seat panel while the left side is suspended. The suspension provides relaxation, and these three modes can be alternated, completely solving the technical problems of poor blood circulation and blocked meridians after prolonged sitting. It has excellent health and exercise functions, with a simple structure, low cost, and low energy consumption when the left and right seat panels move downwards or flip. It can replace a large number of traditional stools and chairs, benefiting the public and improving their health. It is especially suitable for people who need to sit for long periods of time due to office work, some patients, people with disabilities, and overweight people, and its significance and effect on improving their health and exercising are more obvious.
