Description

Multifunctional cervical spine support device

The present invention relates to a multifunctional cervical spine support device, and more specifically, to support the cervical spine of a person when a patient is laid or seated during medical practice or when a person lies or sits on a massage device, etc. It is about an adjustable support mechanism.

The cervical spine is a part commonly referred to as the cervical vertebrae among the vertebrae of our body, and is composed of 7 vertebrae. Each transverse process of the cervical vertebrae has a hole through which the cervical artery passes, around which veins and the brachial plexus are located. It can be said that the lower part is connected to the torso and the upper part is connected to the head. The cervical vertebrae, like the thoracic and lumbar vertebrae, are greatly affected by a person's posture and have various musculoskeletal disorders caused by this. As an example, the same cervical disc herniation as other intervertebral discs may occur, a ligament supporting the cervical spine from the back may be sprained, and cervical muscles may also be stiff due to various causes, compressing the nerves, resulting in headaches. Various diseases of the musculoskeletal system, such as cervical pain and shoulder pain, can occur.

In general, when sitting in a chair and working on a computer, driving, or studying, the eyes are often focused on one place, so the neck is hardly moved, and as a result, the ligaments and muscles that support and fix the neck become stiff. . In addition, due to poor posture due to such a life pattern, the waist is bent or crouched, and posture is not correct, resulting in easy fatigue, and strain on the lumbar disc, spine, and musculoskeletal system, causing severe pain and various diseases. When working in a chair, the head is often pushed forward. At this time, the ligaments and muscles of the back of the cervical spine as well as the muscles of the shoulder and back are supported to prevent the head from bending forward, causing tension in the muscles. If it continues for a long time, muscles stiffen, resulting in blood circulation disorders, and the neck of the body weakens and loses its elasticity, resulting in neck diseases including neck discs even with a small impact. Therefore, it is reported that performing stretching and strengthening exercises to relieve the fatigue accumulated in the neck as an exercise for neck health is good for preventing neck diseases.

Therefore, a lot of equipment for stretching or massaging the spine and cervical vertebrae has been developed for patients with spinal problems or the general public, and the need for a device supporting the cervical vertebrae has increased.

Hereinafter, with reference to the drawings, a multifunctional cervical vertebra support mechanism 1 according to the present invention will be described.

1 to 3 are perspective views of a support mechanism 1 according to an embodiment of the present invention.

The multifunctional cervical vertebra support mechanism 1 according to an embodiment of the present invention includes a support plate 100 for supporting the cervical spine and the head, a rail part 200 on which the support plate 100 slides, and an angle of the rail part 200 A cervical vertebrae angle adjustment unit 300 for adjusting and a cervical vertebrae extension unit 400 for sliding the support plate 100 on the rail unit 200; includes.

The multifunctional cervical spine support mechanism 1 according to an embodiment of the present invention includes a support plate 100, a rail unit 200, an angle adjusting unit 300, and a cervical vertebrae extension unit 400, and by their structural movement The support mechanism 1 has three major arrangements.

FIG. 1 shows a state 1 in which the support plate 100 is not tilted or slid as a basic state of the support mechanism 1 of the present invention. 2 shows a state 2 in which the angle of the cervical vertebrae is adjusted by tilting the support plate 100 of the support mechanism 1 of the present invention. FIG. 3 shows a state 3 in which the support plate 100 of the support mechanism 1 of the present invention is tilted and the support plate is slid to stretch the cervical vertebrae. That is, the support mechanism 1 of the present invention may exist in various states to adjust and stretch the angle of the cervical vertebrae.

The support plate 100 of the present invention supports the cervical spine and the head. That is, the support plate 100 of the present invention may be a plate of a certain size formed at a portion where a person's head touches when sitting or lying down. The rail unit 200 is a subject to which the support plate 100 slides so that the support plate 100 can slide and stretch the cervical vertebrae. Since the support plate 100 slides on the rail part 200, the angle of the support plate 100 can be adjusted by adjusting the angle of the rail part 200, and also the angle of the cervical vertebrae can be adjusted. Therefore, the cervical vertebrae angle adjusting unit 300 adjusts the angle of the rail unit 200 . The cervical vertebrae extension unit 400 applies force to the support plate 100 so that the support plate 100 can slide on the rail unit 200 .

In the multifunctional cervical spine support mechanism 1 according to an embodiment of the present invention, the rail portion 200 is hinged to the frame portion 500 constituting the skeleton of the multifunctional cervical spine support mechanism 1, and the cervical spine angle is adjusted. The part 300 is hinged to each of the frame part 500 and the rail part 200, and the rail part 200 with respect to the frame part 500 is formed by the expansion and contraction of the first piston rod 311. It may include a first actuator 310 that adjusts the angle.

The overall skeleton of the support mechanism 1 of the present invention is provided by the frame portion 500. As shown in FIG. 1 , the frame unit 500 may be formed by combining several frames. The rail part 200 of the present invention is hinged to the frame part 500 . Therefore, the rail unit 200 can be moved at a certain angle by rotating based on the portion hinged with the frame unit 500 .

The cervical spine angle adjuster 300 of the present invention includes a first actuator 310 , and the first actuator 310 applies a force for adjusting the angle of the rail unit 200 to the rail unit 200 . The first actuator 310 is hinged to each of the frame part 500 and the rail part 200 . In addition, the entire length of the first actuator 310 is changed as the first piston rod 311 is stretched and contracted. Accordingly, the angle of the rail unit 200 with respect to the frame unit 500 may increase as the first piston rod 311 is increased. It is natural that the first actuator 310 may include a motor unit that transmits a driving force.

In the multifunctional cervical vertebra support mechanism 1 according to an embodiment of the present invention, the cervical vertebrae angle adjusting unit 300 is rotatably coupled between the frame unit 500 and the first actuator 310, and the position is A first movable hinge whose position is changed according to the movement of the rail part 200 while rotatably coupling between the fixed first fixed hinge 320 and the rail part 200 and the first piston rod 311 330 and a first vertically extending frame 340 extending downward from the rail unit 200 in a vertical direction and coupled to the first movable hinge 330 .

5B shows the cervical spine angle adjusting unit 300 in state 1 of the support mechanism 1 of the present invention, and FIG. 6B shows the cervical spine angle adjusting unit 300 in state 2 of the support mechanism 1 of the present invention. shows The cervical spine angle adjusting unit 300 of the present invention may further include a first fixed hinge 320, a first movable hinge 330 and a first vertical extension frame 340. The first fixed hinge 320 is rotatably fixed between the first actuator 310 and the frame unit 500 . The position of the first fixed hinge 320 is fixed and exists at the same position regardless of the first to third states. The first movable hinge 330 is rotatably coupled between the rail unit 200 and the first piston rod 311 . The position of the first movable hinge 330 is changed according to the expansion and contraction of the first piston rod 311 and the rotation of the first fixed hinge 320 . The first vertical extension frame 340 extends downward from the rail unit 200 in the vertical direction and transmits the force of the first piston rod 311 applied to the first moving hinge 330 to the rail unit 200 do

Referring to FIG. 5B, when the support mechanism 1 is in state 1, the first piston rod 311 exists in an unextended state, and a certain angle (a) between the frame portion 500 and the first piston rod 311 can be seen formed. Referring to FIG. 6B, when the supporting mechanism 1 is in state 2, the angle of the rail 200 with respect to the frame 500 increases as the first piston rod 311 extends and pushes the rail 200. you can see doing Since the rail unit 200 is hinged and fixed to the frame unit 500, the angle of the rail unit 200 can be adjusted even by linear extension of the first piston rod 311.

As shown in FIG. 5B, when the support mechanism 1 is in state 1, a predetermined angle a between the frame portion 500 and the first piston rod 311 may be formed from 7 degrees to 10 degrees, most preferably may be formed at 8.5 degrees. When the predetermined angle (a) is formed to be less than 7 degrees, excessive extension of the first piston rod 311 is required to raise the angle of the rail part 200, and when formed to be greater than 10 degrees, the first piston As the rod 311 is deployed, the angle of the rail unit 200 sensitively changes, causing a problem that the user's neck may be bent too quickly. Most preferably, when the predetermined angle (a) is formed at 8.5 degrees, the angle between the frame portion 500 and the support plate 100 in state 3 of the support mechanism 1 is easily formed at 15 to 19 degrees, It becomes easy to apply an appropriate angle to the cervical spine.

In the multifunctional cervical vertebra support mechanism 1 according to an embodiment of the present invention, the cervical spine extension unit 400 is hinged to the frame unit 500 and the support plate 100, respectively, and the second piston rod 411 It may include a second actuator 410 that allows the support plate 100 to slide on the rail part 200 by the expansion and contraction of the.

The cervical spine extension unit 400 of the present invention includes a second actuator 410, and the second actuator 410 applies a force to the support plate 100 to move the support plate 100 on the rail unit 200. . The second actuator 410 is hinged to each of the frame portion 500 and the support plate 100 . In addition, the entire length of the second actuator 410 is changed as the second piston rod 411 is stretched and contracted. Therefore, as the second piston rod 411 is stretched, the support plate 100 moves in the direction toward the person's head on the rail part 200. Therefore, when the second piston rod 411 is stretched, an effect of stretching the cervical vertebrae occurs. It is natural that the second actuator 410 may include a motor unit that transmits a driving force.

In the multifunctional cervical vertebra support mechanism 1 according to an embodiment of the present invention, the cervical spine extension unit 400 is rotatably coupled between the frame unit 500 and the second actuator 410, and the position is fixed The second fixed hinge 420, the support plate 100 and the second piston rod 411 are rotatably coupled and the position is changed according to the movement of the support plate 100 A second movable hinge 430 , The second vertical extension frame 440 extending vertically downward from the support plate 100 and the second moving hinge 430 extending in parallel with the support plate 100 from the second vertical extension frame 440 It may include a second parallel extension frame 450 coupled with.

Figures 5a and 6a show that the cervical extension unit 400 is not stretched in states 1 and 2 of the support mechanism 1 of the present invention, and Fig. 7a shows that in state 3 of the support mechanism 1 of the present invention It shows that the cervical spine expansion unit 400 has increased. The cervical spine extension unit 400 of the present invention may further include a second fixed hinge 420, a second movable hinge 430, a second vertical extension frame 440 and a second parallel extension frame 450. The second fixed hinge 420 is rotatably fixed between the second actuator 410 and the frame unit 500 . The position of the second fixed hinge 420 is fixed and exists at the same position regardless of the first to third states. The second movable hinge 430 is rotatably coupled between the base plate 100 and the second piston rod 411 . The position of the second movable hinge 430 is changed according to the expansion and contraction of the second piston rod 411 and the rotation of the second fixed hinge 420 . Referring to FIG. 8 , the second vertically extending frame 440 extends downward from the support plate 100 in the vertical direction. In addition, the second parallel extension frame 450 extends in parallel with the base plate 100 from the second vertical extension frame 440 . The second vertical extension frame 440 and the second parallel extension frame 450 serve to transmit the force of the second piston rod 411 applied to the second movable hinge 430 to the base plate 100. In FIG. 8, looking at the second parallel extension frame 450, it has a 'd' shape. This part is a pressure sensor and can measure the pressure received by the second parallel extension frame 450 . Therefore, the second extension frame 450 receives the load transmitted from the support plate 100, and when a certain pressure or more is measured, it is determined that there is a risk of destruction due to structural fatigue and is designed to notify the user. .

Referring to FIG. 5A , when the support mechanism 1 is in state 1, the second piston rod 411 exists in an unextended state. Referring to FIG. 6A, when the support mechanism 1 is in state 2, as the angle of the support plate 100 is changed, the distance between the second fixed hinge 420 and the second movable hinge 430 is changed so that the second piston rod ( 411) is extended, but the extension of the second piston rod 411 is not made for the sliding of the support plate 100. Referring to FIG. 7A , when the supporting mechanism 1 is in the state 3, it can be seen that the second piston rod 411 is extended to slide the supporting plate 100 on the rail part 200.

As shown in FIG. 7A, when the support mechanism 1 is in state 3, the predetermined angle b between the frame portion 500 and the second piston rod 411 may be formed from 5 degrees to 9 degrees, most preferably may be formed at 7 degrees. When the predetermined angle (b) is less than 5 degrees, the angle between the second parallel extension frame 450 and the second piston rod 411 increases, so that the force of the second piston rod 411 is completely applied to the second parallel extension frame. 450, a force loss occurs, and a burden is applied to the second actuator 410 accordingly. In addition, when the angle is greater than 9 degrees, the second actuator 410 must be further spaced downward from the frame portion 500 in the vertical direction, resulting in a problem of increasing the thickness of the mechanism 1.

At this time, as shown in FIG. 7A, when the support mechanism 1 is in state 3, the distance c between the second fixed hinge 420 and the second movable hinge 430 is the second fixed hinge 420 in state 2 Compared to the distance (d) between the and the second movable hinge 430 may be increased by 40% to 50%. If the increase rate of c to d is less than 40%, the extension of the second piston rod 411 is not sufficient, so the stretching effect cannot be properly applied to the cervical spine, and if it exceeds 50%, the second moving hinge (430 ) and the main body of the second actuator 410 is excessively large, and stress due to the weight of a person's head acts on the first fixed hinge 320 excessively, which may cause a problem in durability.
