Description

{A CHAIR for traction cervical vertebrae}

In the present invention, an elastic body is placed on a support of a headrest such as an office chair and the neckrest can be made by pushing the headrest backward with the head,

It is a chair that is designed to pull the cervical vertebrae while the headrest is turned backward.

The principle of traction is that when the headrest is pushed backward, the pushbars attached to the headrest press down the levers mounted on the bottom of the headrest, and this force acts on the levers, By being lifted up

Chair, cervical spine, and cornucopia.

The present invention relates to a field for strengthening neck muscles, a field for treating neck pain, and a technique field for widening narrowed discs,

Existing products in this area are currently the technology of wrapping the jaws on both sides, or wrapping the whole neck in a circular shape and pulling it up with air or other power to increase the spacing of the narrowed cervical spine.

To solve the problem,

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

Second, this should increase the spacing of the narrowed cervical vertebrae,

Third, it should be convenient to use,

Finally, accessibility and convenience should be improved so that they can be used frequently by anyone.

The present invention provides a method for solving the above problems

So that the headrest formed on the upper part of the chair is supported by the elastic body, and when the headrest is pushed back by giving the force, the headrest itself can be pushed back so as to be able to perform the cornucopia, and furthermore, the cervical vertebra can be pulled.

The method of traction of the cervical vertebrae consists of two methods, one is to install a lever bar, which serves as a lever to lift the headrest between them, and the other is to use air or hydraulic pressure. And a simple method of traction by its own power without a power device.

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.

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.

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, according to the present invention, by repeating the operation of pressing the neck support with the neck forcefully, it is possible to obtain the same effect as lifting the dumbbell by the neck.

The muscle mass is dramatically increased than in the bare hand gymnastics, which is a solution to the underlying neck disease.

In addition, as described later, when the throat is pushed backward, a great traction effect is generated, so that the effect of the individual gain can be seen.

The present invention uses a chair that is in contact with everyday life, so that anyone can easily and conveniently exercise.

It can be done at any time in the office for a while, and it is characterized in that it is constituted enough to move the head backward.

Fig. 2 is a perspective view showing a rear portion of the headrest. Fig.

The present invention allows the headrest to be pushed backward by the head so that it can perform a cornucopia.

As shown in FIG. 1, two large supporting rods 100 are disposed on the front portion of the headrest.

It is larger than usual chiropods, and it plays a role in the entire head when it is tilted backward, unlike the dimension of acupressure, because it keeps the position of air hemostasis (the recessed parts on both sides where the end of the occipital bone ends) when the neck is backward. Called the support rod 100.

The oval-shaped open mouth at the center portion is a laryngeal space portion 101 in which the protruding portion of the occipital region is inserted and the support rod 100 can effectively receive the head.

Since modern people are working with their necks forward, they have a neck and a throat. In contrast, the present invention is suitable for correcting these muscles by tightening their muscles backward.

The essential body of the present invention is assembled in FIG. 6 as a support having the torsion spring 111 (FIG. 6) mounted thereon with a pin 103 serving as a hinge at the lower end of the headrest cover formed in FIG. 3 corresponding to the cover, To move backward.

However, there is a device in which the headrest can move backward and downward when the head is tilted backward (see FIG. 14). The configuration and assembly process of the headrest will be described later,

Let us first look at why these devices are necessary.

As shown in FIG. 23, when the neck is bent backward, the cervical curvature of the cervical spine is not simply rotated around the "I" point of the cortex, but is bent around each cervical vertebra, and the neck is curled with a parabola.

As a result, the radius of rotation is reduced by a when the e line of FIG. 23 is rotated as compared with the case of performing motion while maintaining the straight line.

When the cervical spine is lowered while drawing a curved line when the cervical vertebra is in a straight line, the descending width of the headrest is lowered more than when it is a straight line.

Referring to FIG. 23, this is followed by an additional descent by d of the equator compared with the case of straight rotation.

Further, when the head is tilted backward, the cervical vertebrae do not bend backward but the vertebrae, especially the thoracic spine, are bent backward.

24 will be described below.

(A) The cervical spine whose lower part is the vertebrae and the upper part is the neck part.

The leftmost side of FIG. 24 shows when both the vertebrae and the cervical vertebrae are moving in a straight line, and only the cervical vertebra is bent so that the neck can hardly be tilted.

In this state, it is a fictitious figure that can not be tilted even a few degrees.

In the middle of the picture, only the cervical vertebrae are bent. At this time, the width of the exercise does not increase, and it can not be tugged by force.

The far right side of the map is actually a phenomenon that occurs when you perform a cornucopia, and the spine, especially the thoracic spine, is bent backward.

This can be done in a cornucopia, and the muscles of the cervical vertebrae and the thoracic vertebrae move together to exercise forcefully.

This is because the cervical vertebrae and the thoracic vertebrae are not connected to each other in a straight line structure based on the 'I' point in FIG. 23, but are connected to each other through a linking structure so that the nodes of the thoracic vertebrae and the cervical vertebrae are operated in an organic manner.

The large protruding part of the neck is located at the cervical vertebra No. 7. When the hand is tilted backward, the cervical vertebra is bent in a parabolic shape with each cervical vertebrae being moved in a parabolic shape. When pushing back forcefully, the cervical vertebra moves organically to the thoracic vertebra It can be seen clearly.

Since the headrest is not pushed backward by the normal head weight (normally serving as a headrest), it is necessary to push the head back forcefully. At this time, it is necessary to move to the chest as shown in FIG. have.

Referring to FIGS. 23 and 24

23, there is an additional descent by d of Fig. 23 and a backward inclination to the vertebrae as compared with the case where the neck is tilted by the line e shown in Fig.

25, the headrest is not rotated as shown by the dotted line in FIG. 25, but the central point of rotation is gradually moved backward and downward by the backward inclination of the head to be moved to point b in the diagram will be.

In particular, since the support rods 100 in the headrest are rigidly supported by the tongue, it is necessary to absorb this flow width, which is generated both downward and backward.

Therefore, if you do not absorb it, you will not be able to do anything.

This is illustrated in FIGS. 12 and 13 in correspondence with such a phenomenon.

The mounting degree is shown in Fig.

In the case of ordinary people, there is an additional descent and a large backward phenomenon at about 10 cm.

24A and 24B illustrate the backward phenomenon.

If the cervical vertebra is bent, the backward movement is performed by a degree of the same degree, but in reality, the width becomes large b because it is warped to the thoracic vertebra.

This is why the head rest is not simply mounted but the additional device is installed as shown in Fig.

This is the process of mounting the headless, so let's take a look at the back and look at the structure of the headrest.

Figs. 3, 4 and 5 are portions corresponding to the cover of the headrest, and the supporting body for supporting the headrest is Fig.

The support of Fig. 6 has a torsion spring 111 pushing the headrest cover (Fig. 3) forward at both ends and the lower surface of the plate 109 on which the spring is placed is simultaneously bonded to the point of action 119 (Fig. 7) It is also a plate that pushes up the headrest.

The two supporting tubes (112, first tube) provided at the lower part of the comestible support can be fitted with the compression spring 114 at the bottom.

As will be described below, the support tube for supporting the headrest is composed of three tubes, and the diameter of the tubes is successively increased so that they are sequentially inserted. In the meantime, the tubes are referred to as a first tube , The second tube is called the second tube, the first tube is called the third tube, and the same terms are used below.

And the first pipe is inserted into the tail pipe (second pipe) 104, 115 formed in Fig.

Let's look at the process of fitting the lever.

The lever 122 is formed in a plate shape rather than a circular column as shown in Fig. 7 (b).

Fig. 8 shows a state where the lever 122 is attached to the main body of Fig. 7 (a).

6 (a first tube) as a headrest support, and a lower spring 114 constituted by a compression spring at the lower end of Fig. 6 and serving to lower the first tube, And then the disk 113, which is a finishing agent for fixing, is inserted. When the headrest cover of FIG. 3 is assembled to the shape of FIG. 10, the shape of FIG. 10 is obtained. Thus, the headrest is completed.

The compression spring 114 normally serves to lower the headless support (Fig. 6) so that the fulcrum portion of the lever is lifted up to the upper side, so that the name is called a lowering spring.

On the other hand, the pushbars 102, which are lowered at an angle of 45 degrees to the rear portion of the headrest, are connected to the fulcrum portions of the lever so that the headrests are backward. The point of action 117 of the lever is pressed by pushing up the point of force of the lever and the action point plate 109 of the headrest support (Figure 6) is pushed up to separate the gap between the headrest support (Figure 6) and the retainer (Figure 8) It is the structure to be done.

In the state of Fig. 9, the both pillars 104 are fixed and the fulcrum portion of the lever 122 is pressed, whereby the distance between the headrest supporter (Fig. 6) and the retainer (Fig.

Referring back to FIG. 10, when the headrest is pushed backward, the lowering spring 114 of FIG. 10 is compressed and the headrest is raised.

When the headrest is manually pushed after fixing the lever tube (104, the second tube) serving as a column corresponding to the support portion of the completed chain 10 in the chair, the lower portion of the headrest is raised upward, .

More headrests back? The lower end of the headrest is raised.

Since the head rests on the lower part of the headrest and the head is supported, the principle is that the cervical muscle is pulled up by pushing up the head.

The elastic groove 121 (Fig. 7) flanked at the lower end of the lever) will be described.

As the point of action of the levers increases, even if the neck is pulled up, the neck is not stretched, and the support rods (100) support the head, so that if the levers are not elastic, the headrest can no longer be pushed back.

In this case, the apparatus is provided with the elastic groove 121, whereby the lever 122 is gradually bent while the force is applied, so that the neck can be further tilted backward.

The material of the lever itself has a slight elasticity. In particular, as the elastic groove 121 is further bent, the entire lever is bent so as to have an effect of pulling the neck with a soft elasticity.

In the present invention, when the head is pushed backward, the angle of the neck is bent backward and the force is given to the user for the reason as described above, so that the support rod 100 is firmly attached to the air- It is possible to tow without complicated jaw wrapping devices like the traction devices of

Now, the structure of the intermediate apparatus shown in FIGS. 12 and 13 configured to be able to move backward and downward without attaching it directly to the chair, and the installation process thereof will be described.

This is because the structure of the cervical vertebrae and vertebrae is not a straight line of rotation when the thigh is backwardly moved as described above.

25, when the neck is tilted backward, the center of rotation is not fixed to the point a in the drawing but moved to the point b.

Point b is the point where there is movement backward and downward than point a.

In particular, since the supporting rods (100) are firmly supported by both sides of the back of the head and the supporting rods (100) are firmly supported, the head and the headrest move integrally.

Thus, in the case of the present invention, in which the support bar 100 is supported by the head, the head can be almost prevented from being tilted without such a device.

In the absence of the support rod 100, the headrest and back of the head slip together as the backrest is tilted backward, and unpleasant friction occurs. As the angle of tilting increases, only the upper portion of the backrest comes into contact with the headrest.

In FIG. 13, the reverse plate 136 will first be described.

The two pipes 132 fixed to both sides are pipes of the retrograde pipe 132 (third pipe) into which the geared pipe 104 (second pipe) is to be inserted.

A second tube, which is a geared tube 104, is inserted into the tube 132 (third tube), the bar-shaped lifting spring mounting bar 118 at the lower end of FIG. 7 (a) is inserted into the second tube, (See Figs. 7 and 14)

The other end of the lifting spring 136 is attached to the spring hook 130 (FIG. 13) at the center of the back plate 136 (FIG. 13) The second tube rises by the attractive force of the upward spring 137 constituted by the tension spring and is brought into close contact with the third tube.

As the headrest is lowered, the lifting spring 137 is stretched and the lowering motion of the headrest is absorbed.

The backward plate has a pin insertion port 133 penetrating transversely to the lower end, and is fixed to the bottom plate drawn in FIG. 12 with the pin 126 interposed therebetween.

Next, the process of moving backward will be described with reference to FIGS. 12 and 14. FIG.

The individual coupling of the back plate and the bottom plate is omitted and is shown directly in Fig.

As shown in FIG. 14, the backward plate is normally in close contact with the roller 124 attached to the bottom plate 127 by the action of the backward spring 135 and the roller 124, which is usually composed of a tension spring, And the upper portion of the backward plate is moved backward when it is tilted backward.

After one end of the rope is hooked on the rope hook 131 (Fig. 13) perforated in the upper wing portion of the back plate and the rope is passed through the roller 124 (Fig. 12) And is attached to the backward plate spring 135 fitted to the rear plate spring 135.

This backward spring is made up of a tension spring, and since it is normally installed in a state of considerable elongation, it is pulling the backward plate firmly to the bottom plate.

Then, when the headrest is pushed backward, the backward plate is moved backward to absorb the backward movement trajectory of the headrest.

This is a device that absorbs the backward and downward movements that occur during backward and backward movement.

In particular, as described above, since the support rod 100 is firmly supported by the depression of the occipital region, these devices are indispensable.

14, the height adjusting screw is formed as shown in FIG. 22, and the handle portion is fixed to the lower frame of the chair, and the screw portion 211 is screwed into the bolt hole 128 at the lower end of the bottom plate The bottom plate itself can be raised or lowered according to the turning of the handle.

When the adjustment screw is inserted into the frame of the chair, the knob of FIG. 22 is assembled and the fixing bolt 213 on the side of the knob is tightened, the knob and the adjustment screw are integrally combined.

The diameter of the insertion hole in the chair frame is larger than the diameter of the adjusting screw, so that the height is adjusted according to the turning of the handle. Since the chair is used for personal use, the handle is placed at the lower part of the chair.

Fig. 15 is an explanatory view of a bar that can be pulled by hydraulic if a tube is installed between the first and second pipes and the air or antifreeze is filled in the same structure.

The structure for descent and backward are all the same, but only the headless part is different structure, so we can explain it only.

As shown in FIG. 18, the left side of FIG. 18 shows the corrugated tube 204 to be placed between the first tube and the second tube, and the right side image shows the headless backward. ? And a compression tube 208 to be subjected to compression.

These tubes are filled with air or antifreeze.

Referring to FIG. 16, which is the second embodiment corresponding to the orderly chuckle, there is a mouth portion 203 in which a portion where the wrinkle tube 204 is to be mounted is slightly worn at the central portion.

And the corrugated tube 204 is bonded to this portion using an adhesive, which is shown in Fig.

The pleated tube is placed between the first tube and the second tube so that the pleats are normally folded.

15 is a headrest support corresponding to the first tube.

19A and 19B, a compression tube mounting plate 200 made of an elastic plate to which the compression tube 208 is attached is provided on the upper surface, and a compression tube is mounted on the plate. .

On the other hand, the compression tube has a connection hose 207 connected to the corrugated tube at the lower end thereof, and is connected to the corrugated tube 204 at the lower end through the hose (see Figs. 15, 17 and 19)

When the lowering spring 214 is attached to the lower end of the first tube after the connection, the corrugated tube 204 is normally flatly pressed by the action of the lowering spring 214.

Then, when the compression tube is pressed, the pressure is lowered through the connection hose to the wrinkle tube, and the wrinkle of the wrinkle tube is expanded to push the first tube upward.

The process of mounting the upper compression tube 208 is described below.

The compression tube mounting plate 200 for mounting the compression tube is a leaf spring of an elastic body folded at an angle of about 45 degrees.

It is shown in Fig. 19 that a compression tube is attached to the tube.

The connection hose 207 is lowered through the connection hose 201 shown in Fig. 15 and then connected to the crease tube, and the contact surface of the headrest cover (Fig. 20) and the compression tube is adhered with an adhesive.

The adhesive tube applies adhesive to both the mounting plate 200 and the headrest cover. This is because when the pressing force of the headrest is removed, the mounting plate 200 and the headrest torsion spring 209 are urged So that the tube 208 can be inflated.

The crimp tube must swell up quickly so that the crimp tube can easily return to its original position.

The connecting hose 207 is considerably thicker than the two tubes.

The larger the diameter of the hose is, the faster the pressure between both tubes can be delivered.

The connecting hose 207 must have a clearance between the first tube and the second tube so as not to be normally pressed down by the downward spring 214. The upper end of the second tube is protruded at an interval of a in FIG. .

In other words, a in the drawing is a height equal to the diameter of the connecting hose.

In doing so, the pressure of the compression tube can be immediately transferred to the pleated tube.

Finally, one more thing to do with the compression tube mounting plate 200 is the strength of the mounting plate.

The reason why the press-fitting tube mounting plate 200 is made of an elastic body that can be pushed back is because the section where the press-fitting tube 200 is raised is limited even if the first tube is pushed up while the corrugated tube is elongated.

Because the neck does not stretch like rubber band, the expansion section of the corrugated tube is inevitably small.

For this reason, if the wrinkle tube is not further stretched and the compression tube mounting plate 200 is held without being pushed back, the headrest can no longer be pressed backward, and the neck can no longer be tilted.

However, in the case of using a stretch material pushing the compression tube mounting plate 200 backward, the pressure of the mounting plate 200 slowly increases as pressure is applied. You can tilt your neck backwards.

Pressing the headrest against the neck causes the air in the tube and the elasticity of the compression tube mounting plate (200) to slowly move backwards or backwards. It will be effective to pull the neck spontaneously.

20, the headrest is completed. Other structures as described above are the same as those in the case of using the levers, so the description is omitted.

26, since the headrest is lowered by the extension of the lifting spring 137, it can be considered that it is meaningless to make the gap between the first tube and the second tube described above.

However, this is not so. As shown in FIG. 26, although the headrest itself descends when the neck is tilted backward, the position where the support rod 100 is located and the region where the upper end of the headrest descends are much larger ,

As the leverage acts, the thigh is turned more sharply backward like the dotted line in the same figure, and the head can receive the head at a more right angle.

As shown in FIG. 24, the driving force for lowering the headrest when the head is inclined backward is the curvature of the thoracic vertebrae and the curvature of the cervical vertebrae, The headrest itself will descend, but at the same time, the cervical spine will be stretched while the cervical spine is lowered.

It can be used repeatedly at a few seconds interval, or it can be effective even if the neck is tilted back and held for 20 to 30 seconds.

That is to say, you have very good traction and muscular training, even if you hold it down.

It is also good to have a stretching effect on the muscles even if the muscle is in the state of being pressed while holding back the elastic headless.

This does not increase the viscosity of honey or honey in a short period of time, but it can be compared to gradually increase over time.

Because the muscles remember a certain state, the brain commands the repeated state, and when the pushing is depressed, the muscle is somewhat stretched.

All of the existing traction devices have the inconvenience that both sides of the jaw should be wrapped round or the entire jaw should be rounded, and the neck is lifted up and down in a straight line.

Thus, it is not a condition that can give strength to the neck, so there is no training of muscles, but it keeps a certain state for a long time, so that the brain remembers the state of the muscles and heals.

However, this takes a long time, and there is a difference which can not be compared with the present invention in correction of turtle neck and head neck, which are the most common neck diseases.

As described above, according to the present invention,

It is not necessary to wrap the jaws as complicated as the existing products. (Since the joint of the airfoil and the support rod (100) is supported almost at right angles with the back of the neck tilted and the force pushing the neck backward, There is no obstacle to towing without wrapping),

The fact that traction can be done by backwardly folding to correct the gaebokbok and dongjok,

In addition, when the muscles are in the state of force, the kidneys of the muscles are made so that they become very efficient kidneys (remember the muscles are constant)

It is a very useful invention because it not only becomes a fundamental healing but also the treatment period can be shortened considerably.

In addition, since the chair does not differ from the existing chair, it has excellent accessibility because it utilizes a daily chair.
