Description

Cervical towing chair {chair for stretching cervical vertebrae}

The present invention relates to a chair, and more particularly, to a chair for cervical traction to allow the cervical spine of the body to be corrected correctly or to perform stretching exercises by themselves.

The cervical vertebrae is the uppermost part of the spine, made of seven spines, between the head and spine, with the opening of the vertebral arteries, veins, and sympathetic plexus.

Stress interferes with the transmission of nerves from the brain to each part of the body, usually because the muscles of the neck and back are so tense that the bones are not evenly pulled, and the spine is skewed. And when neurotransmission from the brain to each tissue cell is interrupted, our body's organic relationships are broken.

If the cervical spine is skewed, it also affects the internal organs and nerves associated with it, causing a variety of symptoms. . In addition to the treatment of diseases caused by cervical spine diseases, ordinary people also need regular stretching exercises to straighten the cervical spine for smooth metabolism. In other words, by stimulating the cervical spine or physical exercise can not only relax the entire body and to relieve fatigue, but also the treatment of low back pain, shoulder stiffness, arthritis or organ abnormalities.

 However, in a busy daily life, it is not easy for a healthy general person to periodically perform cervical stimulation. It is also true that purchasing equipment or equipment to assist cervical stretching exercises is burdensome in terms of cost or location.

An object of the present invention for the above problems, to provide a cervical traction chair to be able to conveniently correct the stretching and posture of the cervical spine at any place where the chair can be installed without the help of others.

It is another object of the present invention to provide a cervical traction chair which further includes a massage function, including post stretch.

When the screw shaft rotates, the cylindrical shaft is rotated in the diagonal section. A unit driving device which rotates about an axis and moves up and down, wherein the upper and lower cylindrical cylinders only move up and down in the straight section, being provided symmetrically on the first and second jaw rests; By the drive motor is achieved by the cervical traction chair, characterized in that the first and second jaw rest can be raised and lowered at the same time as the rotation.

According to a feature of the present invention, the heating means for warming the user's neck or jaw portion may be further installed in the first and second jaw rest.

According to another feature of the present invention, one or more of tourmaline, loess, elvan, magnet can be further provided for the massage of the neck inside the first and second jaw rest.

According to still another feature of the present invention, the first and second jaw rests are provided with a cervical traction chair capable of being independently activated by a user's selection.

According to the above configuration, by the simple configuration can be carried out simultaneously with the rotation of the jaw butt, there is provided a chair for cervical traction that can be operated in various modes. In addition, by using a variety of materials beneficial to the human body is provided a chair for cervical traction reinforced with massage function.

Hereinafter, with reference to the accompanying drawings in the detailed description of the present invention will be described in more detail. 1 is a rear view of a chair for cervical traction according to an embodiment of the present invention. Figure 2 is a plan view of the jaw rest of the chair for cervical traction according to an embodiment of the present invention. Figure 3 is a schematic exploded perspective view of a key part of the jaw butt driving device according to an embodiment of the present invention, Figure 4 is a longitudinal cross-sectional view of the coupled state. 5 to 6 is a longitudinal sectional view for explaining the operating state of the jaw butt drive device.

The chair 100 basically includes a seat 102 and a backrest 104 and may optionally have a headrest 106. The first and second jaw rests 2 and 4, which can selectively support the user's neck or both jaws, are symmetrically installed on the seat or the backrest. The first and second jaw rests 2 and 4 are preferably selected from a cushion material and have a shape that can be in close contact with the curved surface of the chin or neck of the body. The first and second jaw rests 2 and 4 can be independently started by a unit jaw restraint drive device having the same configuration. Therefore, hereinafter, the configuration of only one bib drive device 6 for activating the first bib support 2 will be described.

The upright screw shaft 8 is rotated at a low speed in a state in which it is decelerated by the drive motor 10 and the deceleration means 12. The cylindrical cylindrical shaft 14 is male and female coupled to the screw shaft 8. A female thread is formed on the inner circumferential surface of the cylindrical shaft 14 so as to be screwed into the male screw of the screw shaft 8. Since the screw shaft 8 rotates only in a fixed position, the cylindrical shaft 14 undergoes a linear movement in the vertical direction in the drawing (FIG. 1 or FIG. 5) by the rotation of the screw shaft 8.

On the outer circumferential surface of the cylindrical shaft 14, the roller 16 is fixedly installed to protrude. There is one roller 16 shown, but not necessarily limited thereto, and two rollers 16 may be symmetrically installed based on the axis of the cylindrical shaft 14. Preferably the roller 16 is rotatably installed for rolling motion.

The guide cylinder 18 is fitted to the outer circumference of the cylindrical shaft 14 and fixed. The cylindrical shaft 14 is provided with a guide groove 20 having a width greater than or equal to the diameter of the roller 16 so that the roller 16 can be fitted therein. The guide groove 20 may penetrate the side wall of the guide cylinder 18 but may be indented to a certain depth. The roller 16 is inserted into the guide groove 20 to allow the jaw of the guide groove and the rolling friction movement.

On the other hand, the guide groove 20 is composed of an oblique section (L1) and a straight section (L2) continuous to it along the longitudinal direction of the guide cylinder (18). The guide groove 20 includes at least one diagonal section L1 and one straight section L2 (see FIG. 4).

A casing 22 is disposed outside the guide tube 18, and the casing 22 has fixing means such as a bracket so that the casing 22 can be fixed to the backrest 104 of the chair.

According to such a configuration, by the rotation of the screw shaft 8, the cylindrical shaft 14 simultaneously performs a vertical movement and a rotational movement about the axis of the cylindrical shaft 14 in the oblique section L1 of the guide groove 20. In the straight section (L2) it is only vertical vertical movement.

As can be seen here, the specific shape of the diagonal section L1 is a measure for determining the rotation angle of the cylindrical shaft 14. The cylindrical shaft 14 only needs to be able to rotate within the range of 80-100 degrees. Therefore, the diagonal section L1 of the guide groove 20 may be a length and a slope corresponding to the arc having a center angle of 80 to 100 ° along the circumferential direction of the cylindrical shaft 14.

According to the embodiment of the present invention, a planetary gear device is used as the deceleration means 12.

The output shaft 10a of the drive motor is connected to the sun gear 24 of the planetary gear device, and the planetary gear carrier 26 is connected to the screw shaft 8. As a result, the rotation of the sun gear 24 is transmitted to the screw shaft 8 in a decelerated state.

As the deceleration means 12, various methods other than the planetary gear device may be generally employed. In addition, although not shown, a contact switch for controlling the amount of rotation of the driving motor 10 may be provided in the jaw restraint driving device. That is, it is necessary to stop the drive motor when the cylindrical shaft 14 is raised or lowered to the end.

Cylindrical shaft 14 is extended in the upward direction and the jaw rest 2 is connected to be integral with the cylindrical shaft 14 in a perpendicular direction. The rotation of the cylindrical shaft 14 causes the jaw rest 2 to rotate around the axis of the cylindrical shaft.

When the roller 16 of the cylindrical shaft is rolling in the diagonal section L1 of the guide groove, the cylindrical shaft 14 and the jaw butt 2 are vertically raised and lowered and rotated, and in the straight section L2. Cylindrical shaft (14) and the jaw butt (2) is only vertical lifting.

The biped drive device 6 described above is installed symmetrically on both sides of the backrest 104 of the chair by the casing 22 described above.

According to the present invention, a jaw butt support 28 for supporting the connection point of the jaw butt 2 and the cylindrical shaft 14 is provided on the back of the chair 104 or the back of the headrest 106. The bracket 30 is fixedly installed on the back of the headrest 106, and two hinge shafts 32 are installed on both sides of the bracket 30. One end of the support arm 34 is rotatably connected to the hinge shaft 32. A holder 36 is integrally connected to the other end of the support arm 34, and an upper end of the cylindrical shaft 14 is connected to the holder 36. The flat cross section of the portion engaged with the support arm 34 of the holder 36 takes the form of "C" to accommodate the rise and rotation of the cylindrical shaft 14.

The support arm 34 and the holder 36 can more smoothly cope with the angle change by a connecting means such as a universal joint.

Hereinafter, the operation state of the jaw butt will be described with reference to FIGS. 4 to 6.

4 shows a state where the cylindrical shaft 14 is at the bottom dead center. The first and second jaw rests 2 and 4 are open to both sides. The roller 16 is located at the bottom of the guide groove 20.

5 shows a state in which the cylindrical shaft 14 is at approximately intermediate height. The first and second jaw rests 2 and 4 show a state of being raised in the vertical direction while being rotationally started about the axis of the cylindrical shaft 14. The first and second jaw rests 2 and 4 are rotated by about 90 °, and the roller 16 is located at the end point of the diagonal section L1 of the guide groove.

6 shows a state where the cylindrical shaft 14 is at the top dead center. The first and second jaw rests 2 and 4 are in the state shown in FIG. 6 only by being lifted in the vertical direction in the state of FIG. 5. The roller is located at the top of the guide groove 20 after passing through the straight section (L2) of the guide groove.

According to the embodiment of the present invention, the first and second jaw rests 2 and 4 and the jaw restraint driving device 6 thereof respectively installed on the left and right sides can be operated independently. Therefore, the chair for cervical vertebra according to the present invention can be used in various modes. For example, a mode of alternately raising and lowering the left and right jaw rest at regular intervals may be considered. The length of this time may also be optionally adjusted by the user.

According to an embodiment of the present invention, a heating means for warming the user's neck or chin may be further installed in the first and second jaw rests 2 and 4. As the heating means, a heat transfer coil may be used. This is to double the effect of massage or stretching exercises by warming the neck at the same time as the traction of the cervical spine.

According to another embodiment of the present invention, any one or more of tourmaline, loess, elvan, and magnet may be further provided for the massage of the neck inside the first and second bibrests 2 and 4.

In some cases, a vibrator may be further provided in the first and second jaw rests 2 and 4 to further oscillate the neck muscles by vibration.

The core of the present invention is a jaw butt driving device for raising and lowering the jaw butt independently, and further to the other key matters to allow the rotation and lifting of the jaw butt once. Based on these key points, those skilled in the art will be able to make various modifications to the cervical traction chair according to the present invention.
