Abstract

The present invention relates to a chair which allows neck exercise by attaching the occipital region of a user to a headrest and then bending the head of the user back, and can draw the cervical vertebrae by using an armrest. When bending the head back, the headrest descends towards the ground. Thus, a spring is mounted in a support part of the headrest so that the headrest can descend by bending the neck back and can ascend by removing force on the neck and making the neck straight. To achieve the above purpose, the chair equipped with a cervical vertebrae drawing headrest comprises: a fixing rod which penetrates both side surfaces of a headrest and can rotate through the penetrated central part thereof; a central acupressure unit which supports the central part of the occipital region of a user; and side surface acupressure bodies which are formed on both side surfaces of the central acupressure unit and are mounted with a side surface acupressure unit capable of moving horizontally in order to practice acupressure therapy on a side surface of the occipital region. In addition, the frame of the armrest is formed to rotate back and forth such that the headrest can ascend from the descending state by pulling back or pushing forward the armrest. Therefore, the chair equipped with a cervical vertebrae drawing headrest can provide a function to draw the cervical vertebrae of the user.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a chair having a cervical spine,

[0001] The present invention relates to a neckrest (headrest) attached to an office chair, wherein when a neckrest attached to a chair is pushed by a backward force, the neckrest supported by a spring provided on the backrest So that a cornucopia can be performed,

The lowered headrest was pulled up again using an armrest so that the cervical spine was pulled

The present invention relates to a chair having a headrest to which a cervical vertebra is pulled when a neck of a throat is pulled so as to strengthen the muscles of the neck and bring about the pulling effect of the cervical vertebrae.

The present invention is a technology field that broadens narrowed discs as a field for strengthening neck muscles and treating neck pain.

As a conventional technique in this field, there are various kinds as shown in FIG. 28, but all of them use a method of pulling the head to the top of the head by wrapping the jaws and the backs together,

In addition, some chairs are used, but all of the methods are pulled around the jaw, and the power of towing is also selected by using the hydraulic system which is installed separately.

All of these conventional techniques are methods of pulling the cervical vertebrae with the neck straight up

The present invention is fundamentally different in that since the traction is performed in a state in which the neck is being pushed backward while the neck is being pushed backward, the back of the head is used mainly and the muscles of the cervical vertebra can be raised by a cornucopia

In particular, in the case of the third and fourth figures of Fig. 28 using a chair, the power of the towing is used by hydraulic pressure, and the operation switch must be separately provided beside the armrest. However, the present invention uses the armrest of the present invention, There is a fundamental difference.

Prior art using armrests may be applied to

10-2015-0023027, and 10-2016-0066973. However, the present application is based on the fact that the practicality and convenience of the headrest portion are enhanced and the apparatus for pulling up using the armrests is installed on the back plate instead of the chair base, It is characterized by improved convenience.

To solve the problem,

First, strengthening the muscles of the neck is a fundamental treatment, so the muscle mass of the neck should be increased,

Second, the interval between the narrowed cervical vertebrae should be increased,

Third, it should be convenient to use,

Fourthly, it is necessary to increase accessibility so that everyone can use it more frequently.

The present invention provides a method for solving the above problems

A headrest formed on the upper part of the chair is provided with a finger pressure sphere which serves as a headrest so that the lower end of the back of the head where the head ends is stably straddled, So that the headrest can be lowered smoothly.

(The neckrest can be tilted backward when the headrest is lowered, which will be described later)

The finger pressure sphere has a central pressing part 102 in the center, which is the main role, and a side pressing part 114, which supports both sides of the back part while supporting the head,

The side pressure foot rest 103 can move to both ends of the head rest when it is not needed, so that the head rest can function as a head rest normally.

The reason for attaching finger pressure sphere

When the first neck is tilted backward, the contact between the head and the acupressure ball is made smooth by the rotation of the acupressure tool,

Second, the contact area between the back and the back is shifted up and down to increase the effect of the scalp.

Disc disease is fatal to humans making upright walking.

The modern working environment is that the spine and cervical discs are forced to squeeze all day because they have to sit and work.

Nevertheless, unlike other muscles, cervical muscle has little chance of being trained.

The usual neck movement is to turn the head to the left or right, or to move the head back and forth.

A common method of cornucopia is to push the left head of the right upper head to the left with the bottom of the right hand while simultaneously training the muscles to mutually push the head in the right direction in correspondence with the force of the right hand.

In addition, as mentioned above, the opposite force is to make a cornucopia.

At this time, the muscles of the cervical vertebrae are strengthened by the mutual pushing force given to the neck by the force.

However, it is not easy to take time for these exercises separately.

Therefore, the muscles of the throat weaken, the throat continues to be thrust, eventually the disc is pressed.

To solve this problem, the above-described apparatuses are used.

But what they have in common is that they do not move with their heads pulled up.

The problem with this method is that the muscles can not be trained because the head is fixed in the pulled state.

Exercises for neck muscle training are rarely used with the exception of the bare hand exercises illustrated above.

When exercising the muscles of the limbs, the heavier instruments such as dumbbells and weights are used to increase the amount of muscle, but in the case of the neck, all of the bare hand movements as described above.

However, the present invention can be compared with the effect of lifting the dumbbell by the neck because it repeats the action of lifting the neck with force.

The muscle mass is dramatically increased compared to the bare hand exercises, which is a fundamental solution to the neck disease.

In addition, as described later, when the throat is tilted backward, a good traction effect is generated, so that the effect of a single gain can be seen.

Another advantage of the present invention is that anyone can easily and conveniently exercise.

The apparatus of the physical therapy room and the various types of apparatuses shown in FIG. 28 are not easy to exercise at any time even if the effect is different.

However, the present invention can exercise very easily in that it uses a chair that contacts daily.

It can be done at any time in the office, and it is enough to move the head backward.

In the present invention, the head end of the head of the occiput is in contact with the headrest,

When the neck is turned backward, the headrest is lowered in the direction of the ground by the principle of the motion locus shown in Figs. 26 and 27 on the structure of the cervical vertebra composed of a plurality of intervertebral discs.

Due to the phenomenon that the headrest is lowered when the neck is tilted backward, a backrest spring 219 is placed on the headrest support 105 so that the headrest can be moved up and down,

When the headrest is lowered when the neck is tilted backward, and the neckrest is restored to its original position, the headrest, which has been lowered by the backing spring 219,

In the second case, the cervical spine is pulled while forcibly lifting the headrest by using the armrest and the traction cable 217, which is a power transmission line, in a state where the headrest is lowered (the neck is in the backward state) Is the second function of the present invention.

The principle of the descent of the headrest is described in detail in the applicant's application form, which is briefly described below.

26 and 27,

Because the human cervical vertebra is made up of multiple discs,

The straight line does not rotate about the 'A' point in FIG. 27, and each cervical node is slightly bent. Therefore, when it is tilted backward by the line e in FIG. 27, it is lowered in the direction of the paper by b + d .

Then, as the radius of rotation becomes smaller, the rotation becomes smaller as shown in FIG. 27A.

This principle causes the headrest to fall down when the headrest (precisely, the central pressure applying member 102) is placed near the point a in FIG. 25 where the rear femur ends, and the neck is lowered backward. cm.

15 is a back spring 219 composed of a tension spring as shown in FIG. 15, and the head rest support 105 is long so that the back spring 219 can be smoothly operated, So that it flows.

The headrest support 105 is united at the lower end by a headrest support lower-end fixing bar 220 and a fixing screw 231,

Since one end of the back spring 219 is connected to the lower end fixing bar 220 of the head rest support

The head rest, the head rest support 105 and the head rest support lower end fixing bar 222 are lifted up and down by a single body (see Figs. 15 to 18).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof,

First, let's look at the structure of the headrest.

The headrest of the present invention shown in FIGS. 2 to 9 is useful only when there is a device that can move the headrest upward and downward by the play spring 219 as described above.

This is because, in the case of the present invention, in which the headrest rests on the lower recessed portion of the occipital region, the neck can not be tilted backward unless there is a structure in which the headrest is lowered downward.

However, this phenomenon that the headrest is lowered when the neck is tilted backward is the starting point of the present invention, and it becomes a body.

In the present invention, it is necessary that the head and the headrest are closely adhered to each other.

A headrest skeleton 112 (FIG. 3) having a semicircular side surface finishing material 104 on its zero side;

A central pressurizing opening 102 (Fig. 7) in contact with the midline of the lower occiput;

A side pressure supporter stand 103 (Fig. 6) equipped with a side pressure applying tool 114 (Fig. 4) for contacting both side surfaces of the occiput;

An acupressure-torquing rod 110 for coupling the central epilogue valve 102 and the side pressure-receiving pedestal 103 with the skeletal body 112 (Fig. 3) of the headrest; And

Both the central pressure applying member 102 and the side pressure applying member 114 have a through-hole at the center and are mounted so as to be rotatable after the connection. (See FIGS. 4 and 7)

The side pressurizing tool 114 is fixed to the side pressurizing tool rest 103 (FIG. 6) by the side pressurizing tool fixing screw 116 shown in FIG. 5, and after it is fixed, So that it was rotated without any difficulty.

)혈 자리라 불리는(도25의 a부근)The center presser foot 102 is larger than the side presser foot 114 and almost reaches the size of the golf ball,

) (Referred to as " a " in Fig. 25)

When the head is brought back into contact with the center of the occipital region, the central pressurizing mouth 102 is squeezed on this portion, and the headrest is lowered with close contact

When the armrest is pulled backward or pushed forward in this state in which the headrest is lowered, the headrest is forcibly lifted and pulls the cervical vertebrae, and the effect of acupressure is also generated in this process (refer to FIGS. 2, 7 and 15)

The headrest shown in Fig. 1 is obtained by finishing the headrest with a stretchable span cloth as a finishing material. Since the inside of the headrest is large as shown in Fig. 2, the portion actually contacting the head is divided into a central pressure- Only the side pressing portion 114 is provided.

When not in use, the side pressure members (103, 114) are pushed to both ends of the headrest so that they do not come into contact with the head. In this case, only the central pressure member and the span member as the covering member come into contact with the head, It will be done.

Since the span cloth is stretched and gently contacted, it has an excellent advantage both in terms of touch and function than the conventional headrest.

When the neck is tilted by giving a force in this state in which the neck is tilted and rested, the covering material, which is a covering material, is made of spun cloth, so that it is easily stretched and the central pressurizing mouth 102 and the occiput are closely contacted.

The reason for the rotation of the acupressure sphere is that the angle of the neck is getting larger and the contact area between the acupressure and the larynx is not correct, but the acupressure sphere is rotated,

In addition, when the rotation is performed, the contact portion moves up and down to bring friction of the scalp, thereby improving the blood circulation of the head.

It is possible to make contact while moving the width of the line 'G' in FIG. 25 up and down.

For example, when the neck is pushed backward with the central pressurizing opening 102 slightly in contact with the upper part of the point a in FIG. 25, the angle of the tilting is gradually increased so that the central pressurizing opening rotates while contacting with the scalp, When you reach the deeply worn part and slowly build your throat again, you will return to the first place with the central pressure gauge reversing.

In this process, the muscles of the neck are also exercised, but the effect of the center pressure squeeze stimulates the scalp and becomes a chiropractic effect.

This phenomenon and the effect are the same for the side pressure applying member 114 as well.

Since the important hemorrhagic region of the head is located in the occipital region passing through the carotid artery and various nerves, when the present invention is used frequently during work, there is an excellent effect in improving blood circulation and relieving stress.

In the case of the side pressurizing tool 114, the side pressurizing tool holder 103 is coupled to the side pressurizing tool holder 103 using the side pressurizing tool fixing screw 116, and the side pressurizing tool, the fixing screw, and the pressurizing tool holder are shown in FIGS. have.

The side-pressure-applying base 103 is configured to be movable from side to side after being coupled with the headrest skeleton body 112 by using the orthodontic appliance. Reference)

However, since the shape of the head is in the form of a sphere, it is necessary to provide a device capable of fixing the acupressure sphere in a desired position. The configuration of the tooth portion 111 and the engagement pin 121 shown in Fig.

As shown in the lower circle of FIG. 7, when the force is applied to the side pressure applying tool 114 after the coupling, the joint pressure is received in the direction of the paper, They are strongly separated from each other without being separated from each other.

When the side fingernail rest 103 is pushed up slightly, the teeth and the engaging pin are separated from each other.

The spacing of the teeth is made as fine as possible and the engaging pin 121 is made of very thin steel like a hacksaw blade so that the width is adjusted in delicate units.

This is because the skull of a person feels differently from a very delicate section, and the effect of acupressure is different.

In other words, it is to be able to enjoy the effect of acupressure while adjusting in delicate units.

The tooth portion 111 is processed only in a section where the head and the side pressing means 114 are in contact with each other and the remaining portion is processed in the plane portion 113. When the side pressing means is not used, Let it be pushed.

The outer shell is spun, so that the outer shell is pushed and spontaneously pushed to the right and left ends, and the engaging pins 121 are caught in the both end fixing grooves 125 at the ends.

In other words, the side acupressure squeeze is used only when necessary, and when not in use, it is pushed to both sides so that the central acupressure 102 and the outer cloth can function as a headrest.

Therefore, it is characterized in that the headrest is configured to be significantly longer left and right than the normal headrest.

Since the side pressurizing tool 114 is configured to rotate, it is possible to stimulate the scalp while moving up and down the width of the upper and lower two lines shown in Fig. 25 depending on the angle at which the neck is pushed back, (102).

As described above, the side pressurizing pad holder 103 can be moved to the left and right to contact a desired site,

When the neck is pushed deeply back into the vicinity of the biceps and the biceps are tilted, the side pressurizing tool 114 is contacted to the angular part of the mandible. In this state, the headrest and the head are well retained

If you lower your body in this state and wait for a certain period of time, you will be able to see the effect of cervical traction with a very relaxing rest.

The above description has been made on the case of a single side pressure gauge, but the side pressure gauge may be installed as a pair of upper and lower side as shown in FIGS.

In this case, the twin-pressure pedestal base 122 having the two upper and lower acupressure bases is installed so as to be rotatable by using the fixing screw as shown in FIG. 5 in the side pedestal base pedestal 103 described above. 9)

In the case of a pair of upper and lower pairs, the pressure applied part is wider than that of the single pressure piece as described above. As the head is tilted, the pressure applied to the upper and lower pressure parts is automatically adjusted There is an advantage.

The reason why the above processes are possible is because the headrest moves up and down, and the configuration for allowing the headrest to move up and down has been discussed above.

In this way, the headrest is lowered when the neck is tilted backward. From now on, the process of pulling the cervical vertebrae while forcibly lifting the lowered headrest using the armrest will be examined.

The configuration for pulling the cervical vertebrae using an armrest configured to be pivoted back and forth in a state in which the headrest is lowered is a technique precedent to the above-mentioned applicant's other application.

However, in the present application, by attaching the pull cable 217, which is a power transmission line for towing, and the device for connecting the pull cable 217 to the back panel, compared with the prior art in which a series of devices are mounted on the base of the chair

It is characterized by the fact that the production process and the assembly process are simplified and facilitated and its utility is enhanced.

In other words, the length of the traction cable is smaller than that of the chair, and the bending of the traction cable is reduced, so that the efficiency of the power transmission is increased. The process and efficiency Is much higher.

The configuration for allowing the armrest to rotate back and forth and the cervical traction procedure are described below.

A diagonal armrest frame 213 (Fig. 13) in which a fixing lever 211 and a tilting lever 210 are formed at a lower portion of the frame in parallel with the grip portion 101;

A chair lower body (Fig. 12) coupled to the chair base plate so that the armrest frame 213 is pivoted back and forth;

And a through hole 215 or 215a through which one end of the fixing lever 211 and the pull lever 210 are passed is formed with a seat back plate 214 having perforated holes on both sides of the lower portion thereof;

A back spring mounting plate 228 (Fig. 16) mounted to the rear central portion of the chair back plate;

An upper traction cable rest 225 fixed to the center of the backrest spring suspension plate 225;

A headrest support pedestal fixing block 227 fixed to both sides of the lower portion of the backrest spring control board and having a headrest support pedestal 230;

A lower traction cable rest 242 located above the traction lever 210 protruding from the backrest,

A tow cable 217, which is a power transmission line connected between the upper tow cable rest 225 and the lower tow cable rest 242;

A pair of headrest supports 105 for supporting headrests provided so as to move up and down on the chair back plate 214;

A headrest support lower-end fixing bar 220 attached to a lower end of the headrest support 105;

A backrest spring 219 connected to the headrest support lower fixing bar 220 and the wire 218 inside the tow cable;

Etc.

The details are as follows.

A pull lever 210 having a handle portion 101 at both ends of a diagonal armrest frame 213 drawn in FIG. 13 and having one end of a pull cable connected to the lower portion of the armrest frame in parallel with the handle portion

And a fixing lever 211 which serves to fix the armrest so as not to move normally is usually provided (Fig. 13)

The structure and the appearance of the bar arm rests 206 and 207 for fixing the armrest frame to the chair base plate are shown in FIG.

Fig. 12 shows a state of the chair lower body in which the armrest thus manufactured is coupled to the base of the chair.

12 that both the pulling lever 210 and the fixing lever 211 are protruded backward longer than the chair base plate 208. [

14 and 15, the connecting lever of the pull cable 217 and the fixing lever detachable bar 241 (FIG. 20) for holding the armrest in a non-moving manner are all provided on the back plate.

In this way, the above-mentioned prior art in which these devices are installed on the base of the chair

There is an excellent advantage in terms of difficulty and efficiency of work.

The process of mounting the back spring 219 to support the headrest by pushing it upward and the process of forcibly lifting the headrest to be lowered for traction of the cervical vertebra will be described with reference to FIG.

One end of the traction cable 217 (Fig. 21) is connected to the lower traction cable rest 242 to which the small roller 221 is attached at the lower left side of the same figure,

The other end of the traction cable 217 is connected to an upper traction cable rest 225 at the center upper portion of the same figure, and then one end of the wire 218 mounted inside the traction cable is connected to the traction lever 210 And the other end is connected to the back spring 219.

The other end of the back spring 219 is connected to the lower end fixing bar 220 of the headrest support so that the headrest support 105 is lifted up due to the contractive force of the back spring 219 and the headrest is supported.

When the neck is turned backward, the back head is pressed in the direction of the ground by the bending characteristic of the cervical vertebrae, and the head rest spring is lowered as the back spring 219 is stretched.

When the neck is set up again, the head rest is lifted up due to the action of the back spring 219, and the head is restored.

Thus, it is a basic function of the present invention that the headrest can be moved up and down so that a cornucopia can be performed and a back pressure is applied due to the action of the pressure valve.

In other words, it is a simple operation that the headrest is pushed and released by tilting the neck back without using the armrest. This action strengthens the muscles of the neck, so that the head is also chiropractic.

In most higher animals, including humans, the muscles in the neck that support the head are located in the back of the neck called the back, where the muscles support the head and the muscles weaken, resulting in various neck disorders.

Especially in the case of a person who lives upright, when the muscle weakens, a disc disease called a disc occurs.

In addition to muscle training, another advantage of the present invention is that the intervertebral disc is widened and refined due to the reaction of the back spring 219 even if only this operation is repeated.

This is because the force of reaction that the head is lifted up by the spring is applied, unlike the action of simply pulling the neck backward.

Next, look at the cervical traction process using the armrest.

In fact, the fact that the action of upward and downward flow only has the function of traction in addition to the effect of muscle training by the action of the back spring as described above.

However, armrests are used for more powerful traction.

15.

As described above, the pulling lever 210 and the fixing lever 211 are rotated from 3 o'clock to 6 o'clock in the clockwise direction when the armrest is pulled back.

(See the right side drawing of Fig. 15, the back spring and the pull string are attached to the wire together with the wire 218 from the upper pull cable rest 225, .)

This pulling line 222 is passed through the inside of the backing spring 219 (since the inside diameter of the backing spring is larger than 15 millimeters, the pulling line is passed into the inside of the spring).

After passing through the punctured pull cord passage hole 229 at the center of the head rest support lower bar fixing bar 220, the force is strongly pressed by the pull cord compression ring 223 from the lower end.

When the pull string is pulled up by pulling the armrest backward because the pull string 223 is larger in thickness and size than the ordinary compression ring used for tying the cable and larger than the pull string passing hole 229,

So that it is caught by the lower end fixing bar 220 of the head rest supporter and pulls up the lower end fixing bar 220 of the head rest supporter.

When the neck is tilted backward, the headrest is lowered, so that the headrest support lower end fixing bar 220 united with the headrest support 105 also slowly descends.

When the neck is lowered by about 90%, the lower end fixing bar 220 of the headrest support is lowered to the 'G' line of FIG. 15 and brought into contact with the pulling ring 223.

The pull cord 223 is in any case raised only when pulling the armrest without lowering below the "G" line of FIG.

This is because the pulling lever 210 and the fixing lever 211 are in contact with the upper ends of the through holes 215 and 215a of the back plate. (See Fig. 15)

When the head rest rest lower leg fixing bar 220 reaches the 'G' line of FIG. 15, the neck is significantly bent back and the neck muscles are significantly undergoing a force.

When the armrest is pulled backward, the pulling lever 210 is rotated in the direction of the arrow in FIG. 15 to pull the wire 218, and the pulling ring 223 connected to the pulling lever 210 is pulled to the lower end fixing bar 220 of the headrest support The head rest support 105 is pulled up.

Since both the wire 218 and the pulling line 222 are made of a steel material that does not stretch, the pulling force of the armrest acts as a pushing force of the headrest as it is.

The pulling string 222 may be an iron core that does not bend, but uses a thin and thin wire that is bent to avoid a fricative sound generated at a portion contacting the backing spring 219.

The length of the vertical portion of the armrest frame corresponding to the height of the armrest is greater than the length of the traction lever 210, so that an effect of leverage is generated and both arms are pulled at the same time.

Even if there is no pulling cord 222, if the armrest is pulled while maintaining the angle of the neck as it is while the neck is being pulled back to the pulled back, the wire 218 is pulled upward, so that the rising spring 219 is further extended, .

However, since the pulling force requires a considerably strong force, the pulling line 222 which is not stretched is used so as to have a strong pulling effect.

The stronger the ascending force, the stronger the stronger the neck, the stronger the neck muscles are strengthened.

Muscles that are used mainly for strengthening the headrest while lifting the neck backward are mainly used for the middle-upper muscle of the cervical vertebrae. Muscles near the lower cervical muscle attached to the spine are structurally less powerful. (Because the cervical vertebra near the middle part is more distorted)

Therefore, the muscles in the lower part of the cervical spine are relatively increased. This is a very useful invention when viewed from the viewpoint that the disk disease occurs mainly in the lower cervical vertebra,

Movement of the back of the neck is a necessary action for the treatment of turtle neck and diabetic neck which is common in modern people, and patients of turtle neck and diabetic neck are usually narrowed forward to the chest, It is a necessary operation.

In fact, back and neck and back at the same time to move the arms back and neck disease and spine disease is a highly recommended action for patients.

Particularly, according to the present invention, it is possible to reduce the width of motion of the neck while tilting the neck backward while adjusting the pulling force of the armrest, that is, to slightly nod the neck to the left or right or back and forth.

It is very different from the conventional method that can hardly move the neck.

This is an effective way to increase the spacing of the narrowed discs. This method is more effective when the armrests are additionally used, which results in narrowing of the narrowed discs in a short period of time.

A nodding motion in the state of strongly towing is likened to the principle of moving a rock when using a lever to move a big rock when the rock is slightly moved, and the disc narrowed down by the action is drastically increased.

Next, the fixing lever 211 of the armrest frame will be described.

The armrest is automatically restored to its original position because the backrest spring 219 normally pulls the tow lever 210 upward (refer to FIG. 15), thereby removing the force of pulling back the armrest.

However, this force is relatively weak (the strength of the back spring can not be strengthened strongly because the corn spring is strengthened by increasing the strength of the back spring). The inconvenience that the arm rests when the chair is moved backward It will be.

This is because people's movements move their armrests together when they move back and forth around the chair.

The end of the securing lever 211 slightly protrudes from the lower right end of Fig.

When the fixing lever detachable bar 241 shown in FIG. 20 is attached to the back plate using the fixing piece 236, the state shown in the right side of FIG. 20 is obtained.

That is, the fixing lever 211 is caught by the lower-end-portion fixing lever-fixing jaw 239 of the fixing lever detachable bar 241, so that the armrest is fixed and the armrest can not be moved backward.

When the headrest is lowered by lifting the neck in this fixed state, the lower end fixing bar 220 of the headrest support is lowered and is pushed like the dotted portion of the right side of Fig. 20 while contacting the slide surface 238 of the fixing lever detachable bar 241 The armrest can be rotated.

Therefore, it is needless to say that the 'A' portion on the right side of FIG. 20 should be easily bent in a state of elasticity.

The above case was when pulling the armrest backward.

Hereinafter, the case of the push type pushing the armrest forward will be described.

In the case of pulling the armrest backward and pushing forward, there are advantages and disadvantages of each. In the case of pulling backward, in the case of a person whose chest is narrowed forward, the neck is tilted backward and at the same time the operation of lifting the arms backward is performed. There is a disadvantage in that it is difficult to make the back and the like closely contact with the back plate.

On the other hand, when the armrest is pushed forward, both arms are pushed forward while the head is tilted backward, so that the back and the headrest can be firmly in close contact with each other.

As shown in FIG. 22, the pull lever and the fixed lever are attached to the front direction, as opposed to the case of FIG. 13, which is a pull pull type pulling the armrest backward.

And when the armrest frame is attached to the chair, the pull lever and the fixed lever will rotate from the 9 o'clock to the 6 o'clock position of the watch (in the case of the pull type, it rotates from 6 o'clock to 3 o'clock) Towing cable holder and fixing lever detachable bar were installed on the base of the chair.

Fig. 23 is a bottom view of the chair thus installed, and Fig. 24 is an enlarged view of Fig.

The other members such as the upper pull cable rest 225 and the back springs 219 to which the pull cable 217 is mounted are the same as those pulled back as described above except that the length of the pull cable is made longer and the lower cable rest is fixed to the chair It's just moved to the base.

The portion of the right second tractive lever 302 in Fig. 24 can be understood without further explanation.

The left part of the diagram is for fixing the second fixing lever 301. The power for operating the second fixing lever detachable bar 304 is the same as that of the pull type as described above in which the lower end fixing bar 222 of the headrest supporting part descends .

However, since the mutual distances are spaced apart, the fixed lever cable 305 is used.

When one end of the fixed lever cable 305 is attached to the second fixing lever detachable bar 304 and the other end is hooked to the lower end portion c of the fixed lever detachable bar formed in FIG. 20, the headrest must be lowered Since the lever can move, the armrest will not move normally.

That is, also in the case of the push type, the fixed lever detachable bar 241 shown in FIG. 20 is attached to the back of the chair.

The height of the headrest needs to be adjusted according to the person.

The headrest height adjusting screw 234 shown in Fig. 19 is used.

The bolt portion is inserted into the support finishing plate 106 (see FIG. 2), which is mounted on the upper surface of the chair back plate with the copper screw as a final finishing member, and then the fixing pin 235 under the screw thread head portion is fitted.

Then, when the headrest height adjusting screw 228 is coupled to the headrest height adjusting screw inserting hole 224 at the upper end of the backrest spring fixing plate 228 in FIG. 16, the backrest spring fixing plate 228 itself is moved up and down along the direction of rotating the height adjusting screw The height of the headrest is adjusted.

The back spring holding plate 228 is fixed by four left and right back spring holding plate fixing blocks 216, but is fixed so as to be vertically movable (see FIG. 15).

When using the present invention, as described above, since the neck is tilted backward, the neck is perfect for correcting the turtle neck which is struck forward, and when the neck is spread to the breast, the neck is moved smoothly.

All joints are surrounded by muscles and the neck muscles are also the same.

If the knee joint is worn, it is recommended to cycle and swim. At this time, the muscles around the joint are strengthened, so it is treated.

The muscles are strengthened and the gap between the joints is widened even though there is no process of pulling the knee to the cycle or swim. This is because the muscles are surrounded by the shrinking fascia and the muscles are not only thickened to the side but also become long.

The strengthening of the neck muscles means that the effect of traction can be seen by itself. Thus, the present invention will be an invention having a significant significance even if the strengthening of the muscles is performed aside from traction.

It is the neck that connects the head and each part of the body.

When the neck is overloaded, the shoulder is broken. This is because the neck is weak and it is overloaded.

Since the contact portion of the head of the present invention is a sphere which rotates, when the neck is tilted, the sphere is rotated to rub the upper and lower parts of the occipital region. Therefore, It will clear the mind.

And the fundamental healing of neck disease is that there is no other way but to strengthen the neck muscles.

As mentioned above, since most of the muscles of the neck are on the back, exercising to back the neck is the best condition for the treatment and prevention of cervical disease.

Finally, since most of the devices are hidden under the backboard and the chair, the appearance of the present invention is the same as that of the existing chair, and there is no sense of resistance to the appearance.

If the head rest part is also placed on both sides of the side bearing body, the covering cloth, which is the covering material, supports the head like a net swinging hammock.

You can use it without any manipulation, just turn your neck back,

Accessibility can also be encountered on its own because it is a chair that comes in contact all day if you open your eyes.
