Description

Chiropractic Chair {Chair for Rectification Vertebral Column}

The present invention relates to a chair for chiropractic, and in particular, it can support the narrow part (狹 細部), such as a seated person, and can distribute the load due to the weight applied to the waist disc through the configuration that can support the armpit Related to a chiropractic chair.

In general, a disc is a disk-shaped joint that is sandwiched between the nodes of the spine, from the neck to the lumbar spine of the spine. The upper and lower sides of the disc are cartilaginous plates in contact with the vertebrae. The outer periphery of the disc is surrounded by elastic annular fibers, and the inner core of the disc contains a soft nucleus.

If the nucleus pulposus serves as the center of the disk, and the annular fiber is likened to the rubber wheel of a car tire, the nucleus pulposus corresponds to a tube containing air. The nucleus pulposus is a slime protein that contains a lot of water, which acts as a cushion to absorb the impact on the spine, and also serves as a joint that facilitates the movement of the spine.

As a result of measuring the weight-induced weight of the lumbar disc according to the change in body position, if you lie down, the impact is the smallest and about 1/3 of your weight is applied. If you are standing, you are about half and half your weight, and if you sit without leaning on the chair, the impact on your waist disc is about twice as much as your weight.

In addition, because the impact on the lumbar spine is more severe than sitting when standing, many patients complain that the most painful symptoms of the disc.

Referring to the chair as described above with reference to Figure 1, first composed of the leg 11, the seat plate 13 and the backrest 15, the leg 11 is provided on the lower portion of the chair 10 and It has a structure for supporting the seat plate 13 and the backrest 15 provided to prevent the chair from falling when seated.

In these figures, reference numeral 10 denotes a chair. The chair 10 is formed integrally with the leg 11, the seat plate 13 which is mechanically connected to the upper end of the leg 11, and seats the seat of the seat of the seater, and the seat plate 13, The backrest 20 supporting the back, the hook portion 30 which protrudes horizontally forward from the backrest 20 integrally to support the seating armpit, and is formed on the top of the backrest 20 It is composed of cervical support means 40 to support and support the seated cervical spine rear portion.

The backrest 20 has a curved portion 21 is formed so as to have the same curve as the spine curve of the seated person, the projection 22 is formed in a vertical direction at the position where the narrow portion (狹 細部) such as a seated person is in contact with the center portion The hook portion 30 protrudes horizontally toward the upper end thereof.

At this time, the backrest 20 is formed in such a way that the outer periphery is bent inward by a predetermined length so that the back and waist of the seated person can be stably supported.

The hook portion 30 extends forward from the backrest 20 and is integrally formed. The hanger part 30 supports the seater's armpit, thereby sharing the weight applied to the seater's spine, and straightens the seater's spine.

5 to 7b, the hook portion 30 is provided with a height adjusting device 32 for supporting the underside of the seated person at an appropriate position. The height adjusting device 32 is a hook portion ( A hole 322 penetrating the upper and lower directions 30, a vertical ratchet bar 321 installed to be movable upward and downward through the hole 322 and having a ratchet 321a formed on the front surface thereof; A cushion 31 mounted on an upper portion of the vertical ratchet bar 321 to support a seater's armpit, and inserted horizontally in front of the hook portion 30 to operate horizontally in a direction orthogonal to the ratchet 321a. And a stopper 34 for restraining or releasing the vertical ratchet bar 321 to adjust the height of the cushion 31. A button 322b is provided at the front of the stopper 322a to provide a stopper 322a. It is to be used for horizontal operation

Although the height adjustment device 32 is implemented in the present invention by applying a ratchet device, by adjusting the height of the cushion 31 provided on the upper side of the support 33 through another configuration to support the seating armpits It will be alright.

As shown in Figures 2 and 3, the upper back of the back 20 extends along the cervical spine of the seat, the cervical spine support means 40 of the open shape is integrally formed. The cervical spine support means 40 covers and supports the rear part of the cervical spine to prevent the head load from compressing the disc of the cervical spine, as well as preventing the head load from being transferred to the lumbar disc through the cervical spine. Play a role.

Cervical support means 40 may be manufactured separately from the seat and the backrest and assembled through a predetermined fastening means. At this time, the cervical spine support means 40 will be preferably configured to be used while adjusting the length.

In front of the backrest 20, as shown in Figure 8, the upper body support means 20 for pressing the lower armpit of the seater to closely contact the back of the seater to the backrest is rotatably attached. The upper body support means 20 has a band shape that can support while pressing the upper body front part of the seated body while blocking the front part of the backrest in a horizontal direction, and one side thereof is coupled to the end of the backrest 20 by a hinge 51. It is installed to be rotatable and the other side is installed to be detachable by the locking device 52 attached to the other end of the backrest 20.

Referring to the operation of the present invention configured as described above are as follows.

First, the seated person sits in close contact with the seat plate 13 and the backrest 20.
