Abstract

The dynamic neck tension relief pillow is constituted from a movement mechanism and a common sleeping pillow (8), either placed onto the movement mechanism by the user himself, or permanently adjusted onto the movement mechanism, where the pillow's position should be balanced parallel to the neck through the circular eccentric movement due to the user's head and neck weight and the pillow's angle becomes 0 degrees.

Description

This invention refers to a dynamic neck tension relief pillow consisting of a sleeping pillow and a movement mechanism.
Pillows with movement mechanisms are known from EP 0 819 415 A2 . The sleeping pillow is one of those commodities known to everyone without exception, which we can lay on top of the covers of any mattress on any bed for sleeping. Almost all of us use it when we lie down and rest our neck and head on it, either to relax or during our sleep for as long as we are sleeping. The sleeping pillow is simply a classic, whether non-anatomic or anatomic or ergonomic, it can be constructed from natural or synthetic fibres or from feathers or from natural or synthetic foam, and in general it comes in all sizes, kinds and qualities.
Almost all of us, when we go to bed to relax or to sleep, use one of those sleeping pillows which are known to everyone. Our neck and head, from the moment they touch the sleeping pillow, begin to form the arc of a circle, descending lower and lower until the moment they reach their greatest arc and their descending movement onto the sleeping pillow stops. Then the opposing force from the sleeping pillow has become equal and opposite to the weight of our head so that our head balances on the sleeping pillow and does not descend any lower. We observe for now that at the time we start to sleep or rest on our pillow certain forces have been created, the forces created by the descending progress of our head because of its weight and because of the path it followed, that is, the arc of a circle, and the opposing forces which were developed by the sleeping pillow, that is, the reaction to the weight of our neck and head and to the horizontal movement which our head and neck completed synchronously with the tracing of the arc of the circle. These forces are mainly at right angles to our neck as a reaction to the weight of our head, however there are also component forces as a reaction of the sleeping pillow to the horizontal movement which is created from the downward movement of the arc of the circle of our head and neck, which, when calculated, give us a resultant force which is horizontal in relation to our neck. The size of this horizontal force which, according to the situation, changes towards our neck, depends on the hardness of the pillow we are using, on the shape of the pillow, that is, if it is an anatomical or a simple non anatomical sleeping pillow, and on the difference between the height of the sleeping pillow and the size of the person using the sleeping pillow and his/her position in relation to the sleeping pillow. And so, from the moment that our head and neck, when we lie down on our bed to relax or to sleep, comes in contact with the sleeping pillow, until the moment when it finishes its descent and balances on top of the sleeping pillow, it traces an arc of a circle with its centre at the point where the flexibility of our neck begins. We divide this arc of the circle into two parts, the length of the route which is traced by our neck and head above the imaginary straight line of our spinal column and of the length of the route which is traced by our head and neck under the imaginary straight line of our spinal column. When the length of the upper route according to the above is greater than the length of the lower route in relation to the imaginary line of our spinal cord, our pillow creates as a reaction a resultant force which is horizontal in relation to our spinal column and with a direction towards our spinal column, lightly pressing on our spinal column throughout the duration of our sleep. The size of this horizontal pressure on our neck is analogous to the difference in length of the two upper routes which our head traces. If the route below the imaginary straight line of our spinal column is greater than the route which was traced by our head and neck above the imaginary straight line of our spinal column, then we again have the creation of a small horizontal force towards our spinal column, however in this case we have an opposite direction, that is, this small horizontal force has an opposite direction to the side of our spinal column, lightly pulling our neck for the whole duration of our sleep. When this happens it is good, but unfortunately it happens rarely. When this horizontal force to which I referred above has a direction towards our spinal column, in spite of the fact that our spine is constructed so that during the day it receives many and great loads without being damaged, at night when we sleep it is more vulnerable, and especially for someone who has the beginnings of a hernia in one or more of the vertebra of the neck, or if because of deformation of the muscles the space between the vertebrae of the neck has been reduced and the vertebrae press on the intermediary sliding material of cartilage or spinal marrow or some vessel for the transfer of liquids or blood or some nerve lightly at the beginning of deformation, then this horizontal compression stress does not permit the neck and the muscles of the neck to rest well, because they are deformed in our sleep.
Unfortunately when we sleep, most of the time this horizontal compression has an impetus against our spinal column because there is an attempt to choose a sleeping pillow so that during our sleep the imaginary line of our neck will coincide with the imaginary line of our spinal column, with the result that the route of the arc of the circle traced by our neck and head is greater than the upper part of the imaginary line of our spinal column. At the point where the flexibility of our neck starts, many times our neck is not in contact with the
sleeping pillow when we are sleeping on our side. In this case two things happen:

a) Because the weight of our head and neck remains the same, it is distributed in this first case onto a smaller contact area with the sleeping pillow, so we have a greater pressure per cm², and the best thing for our health is for the same weight of our head and neck to be distributed over the greatest possible contact area with the sleeping pillow in order to minimalize as much as possible the pressure per cm² which we receive, in reaction from the sleeping pillow.
b) At the highest point, where our neck is not in contact with the sleeping pillow because of the weight of our head and neck we have per cm² forces with energy perpendicular to our neck and with impetus towards the earth. I believe that these small perpendicular forces are capable of not allowing our muscles and our neck itself to sleep satisfactorily and to rest as much as they need, because of the fact that the muscles of our neck and all the parts which make up our neck receive at this point, in this case, a slight bending which, with time, is enough to create deformation to the members which make up our neck.

We see that the classic, non-anatomic pillows which are familiar to all of us many times present the greatest problems and in spite of the fact that, along general lines, they are good, the people occupied with the evolution and improvement of technology invented the anatomic and the ergonomic sleeping pillows.
The anatomic pillows familiar to us all reduce this force which is horizontal to our neck, the compression stress in relation to the classic non-anatomic sleeping pillows familiar to us all comes into contact better with the whole length of our neck, greatly reducing the small forces vertical to our neck, which as I mention above had the tendency to compress our neck into bending. In this way we also reduce the pressure per unit of surface area because we increase the surface where our neck and head are in contact with the sleeping pillow. Of course, the simple non-anatomic sleeping pillows which are stuffed with natural fibers, with wool, cotton or synthetics, for instance polyester, or the feathers of birds, are also soft, our head sinks into them and since they have a large contact area, we have a reduce pressure towards the points of our neck and head per cm². When we sleep it is better for our body and neck to be compressed with the least possible load, which is moreover the reason why we sleep in a position parallel to the earth using a mattress and sleeping pillow which have been improved, and we are now also trying to improve the sleeping pillow even more so that during the period when we are lying down or when we are asleep we can get the best rest possible, because I believe that rest is the source of life.
According to the present invention as claimed in claim 1, the dynamic neck tension relief pillow has the characteracteristic that it also includes a movement mechanism.
The dynamic neck tension relief pillow comes in two kinds:
In the first kind the sleeping pillow is constructed so that it is permanently incorporated with the movement mechanism.
In the second kind we simply place the sleeping pillow or even place it and hold it steady on top of the portable movement mechanism and we remove it from there whenever we want to.
The dynamic neck tension relief sleeping pillow is portable and in order to use it a person places it on top of the covers of whatever mattress on whatever bed, in the same position in which until today one placed and used an ordinary sleeping pillow. The movement mechanism collects energy in a natural way from the load of the weight of a person's neck and head, and every time it is released from the load of the weight of the person's neck and head, and for whatever height it is released, it returns the collected energy in a natural way by raising one of the 4 sides of the sleeping pillow to the same height as the height which it was released from the weight of the person's head and neck, and specifically, it raises the side of the sleeping pillow which is closer to the point where the mattress ends, tracing an ascending arc of a circle from a 0 degree angle minimum up to a 45 degrees acute angle maximum, and thus it remains waiting in this position while it forms an inclined plane above the covers, and in this position the sleeping pillow is ventilated over the whole area of its lower surface.
Every time a person lies down on the bed to rest or to sleep and lay their neck and head on the neck tension relief pillow with dynamic movement, it starts from the default angle which the person has set earlier and traces the length of a descending arc of a circle, while simultaneously it also covers the length of a horizontal movement towards the imaginary line of the person's spinal column and in a direction opposite to the side of the person's spinal column until the degrees of the angle of the inclined plane go to zero and the dynamic neck tension relief pillow becomes level or almost level above the mattress. The greater the length of the descending arc of a circle, the greater the length of the horizontal movement which the pillow covers, and the smaller the length of the descending arc of the circle, the smaller is the length of the horizontal movement which it covers towards the imaginary line of the person's spinal column.
Every time the dynamic neck tension relief pillow receives the load of weight from a person's head and neck when lying down on the bed and turning and testing with their head and neck on the dynamic neck tension relief pillow and for as much length as it traces a descending arc of a circle until the default angle of inclination becomes 0 degrees, the sleeping pillow finishes its descent on the mattress, and the person's head and neck finish their descent and rest on the sleeping pillow, with an easy earlier adjustment of the default angle, each time it traces as great a descending arc of a circle as the horizontal length it covers, it copies in a natural way and is exactly the same as the horizontal length which the person's head and neck cover every time they go up or down on it. With this adjustment of the angle of inclination in the default position, it neutralizes all the horizontal forces which compress the person's neck and relieves the neck. Usually with this adjustment of the default position, a person uses it for the whole duration of their sleep.
Or when it is necessary, a person pre-sets a little greater incline in the dynamic neck tension relief pillow when it is in the default position so that when the person uses it, it covers a littler greater horizontal length than the horizontal length which the person's head and neck cover and in the same direction. The additional horizontal length the person adjusts at whatever distance the person wants so that in practice the person feels as good as possible when having a problem with incipient hernias to their neck, and uses it throughout the duration of their sleep. The sleeping pillow, because it is softer than a person's neck, changes its shape temporarily and collects the additional horizontal length from the horizontal length given by the person's neck and head, and since it functions like a spring, it converts this into a force of reaction. It returns this force of reaction to the person's neck and head throughout the time when the person is resting or sleeping on it and with the passage of time, it relieves the person's neck of the compression stress. When the person feels better, the person brings back the earlier setting and uses it so that when sleeping the person's neck is not compressed by any horizontal force.
the dynamic neck tension relief pillow consists of one of the raising devices in order to collect and to return the tracing of the arc of a circle and additionally consists of one or two hinges which unite the two levels which make it up, because these are separate. These two hinges are the center for the arc of a circle which the dynamic neck tension relief pillow traces, the sleeping pillow is suspended with an elastic attraction rubber in the default position from the minimum of 0 degrees to the maximum of 45 degrees angle of inclination of the inclined surface, it also includes the setting mechanism for the angle of inclination. When it includes the second raising component it consists of the fixed support which is connected at the lower level, of the movable support, and of the elastic attraction rubber. The movable support is based in the perforated stable support where it is suspended from the elastic attraction rubber on the lower side while on the upper side it is connected to one side of the upper level. The rubber raises the movable support and the movable support raises the upper level and the sleeping pillow to the default position from 0 degrees to 45 degrees maximum every time above the covers on any mattress of any bed. The device for setting the default angle is of course also included.
However many choices are possible among many raising devices:

It can be placed it on the imaginary axis which unites the hingesand is the center of the levels and use spiral springs of any shape and form, in order to collect energy and to return it by raising the neck tension relief sleeping pillow to the default position above the mattress from an angle of 0 degrees to a maximum inclination of 45 degrees.

It is possible to use pulling springs so that with an eccentric connection on the two levels of the first type of movement mechanism, the sleeping pillow will be drawn and will tend to rise to the default position with the centre of the arc of the circle always on the hinges.
It is possible to place a conical helical compression spring between the two levels of the first type of movement mechanism, so that with the hinges as the centre of the arc of a circle, one side of the pillow will rise to the default position above the mattress, always between a 0 degree default angle minimum and 45 degrees maximum.
Of course it is possible with the movement mechanism to use other additional raising components so that the sleeping pillow will be raised to the default position, like for instance counterpoises and other things. supporting component, which a person can optionally place whenever the person wants between two levels of the movement mechanism. It stabilizes and does not allow the raised side of the dynamic neck tension relief pillow to move and to complete a descending arc of a circle, it strengthens the movement mechanism and makes it more resistant to the load of weight and allows the person to watch television or to converse or to read more easily while lying on it, because when the person lies down on it the upper side of the sleeping pillow remains raised.
The advantages of this invention are that the dynamic neck tension relief pillow is a sleeping pillow of the person's choice, any one of the sleeping pillows which are familiar to everyone, which circulate on the market, which everyone has selected and uses today in his/her sleep. If a person uses a sleeping pillow of their choice in conjunction with the movement mechanism, it becomes mobile and gives the advantage of eliminating all the defects which it had until now because of being fixed on top of the mattress. The person keeps all its advantages and new advantages are added, because in a natural way the invention gives movement to all the familiar sleeping pillows which circulate on the market, a movement equal to the arc of the circle and horizontal movement traced by the person's head and neck when lying down and sleeping on the dynamic neck tension relief pillow. It relieves the person's neck from horizontal forces which create compression stress in their neck and since the invention relieves their neck and throat of the energy of horizontal force in the direction of their spinal column, therefore it relieves the person's neck and throat of one of the reasons, because this horizontal force which presses on the muscles and the vertebrae of the person's neck in a direction towards the person's spinal column, or compression stress, is sometimes although not always a cause which creates or continues health problems to the person's neck and throat, since many times deformation is created to various members making up the person's neck and throat, with the passage of time, because it functions by adding.
The dynamic neck tension relief pillow has the advantage that it becomes softer, it absorbs the sudden vibrations, the movements of a person's head and neck on top of it become calmer because it functions as a suspension and gives the person's neck and head the advantage of not receiving sudden compressions but softer ones, balancing on it in a position where it receives the least compression.
We also have the advantage that when a person wants to use a simple classical non-anatomic sleeping pillow of natural or synthetic fibers or of feathers, the person can attach the appropriate additional component to the bottom part of the upper level of the movement mechanism, and this converts the simple non-anatomic classical sleeping pillows to anatomic pillows.
When we see the dynamic neck tension relief pillow is set on the mattress in the default position to allow a person to lie down on it, it forms an inclined plane. In this higher default position I believe that the dynamic neck tension relief pillow has the advantage that is more tasteful to the lady of the house.
In addition in this higher default position the invention gives the sleeping pillow the advantage of being aerated from the bottom side as well, something which I believe is also desirable to the lady of the house because the sleeping pillow becomes healthier for the person.
The movement mechanism converts the sleeping pillows to dynamic neck tension relief pillows in a natural way. The driving force is the load of weight from a person's neck and head.
The great advantage of this invention is that in practice these movements of the dynamic neck tension relief pillow are the same as the horizontal movements which a person neck and head make, when turning their neck and head and resting or sleeping on top of it. The person has the possibility, with the setting mechanism, to set it so that it gives exactly the same length of horizontal movement as their neck and head give and since it also has the same direction, with this setting a person has the possibility of neutralizing the difference in length of movements. In this way the invention achieves the same length of horizontal movement of the sleeping pillow as the horizontal length given by a person's head and neck, so it neutralizes the horizontal force which until today has acted on and compressed a person's head and neck into stress during the time of resting or sleeping on a plain sleeping pillow without a movement mechanism. In many cases the horizontal force which acts on a person's neck with a direction toward their spinal column, with the passage of time and if the person's neck is prone to be sensitive, succeeds in overcoming the muscles' defences and if the person does not use a dynamic neck tension relief pillow one or more than one vertebra give way under the pressure of compression stress, and then a temporary deformation to the various members which make up the person's head and neck begins, and although our organism is healthy, the quality of the person's life and of those around becomes ugly, like for instance, snoring, or when the root of a nerve is lightly pressured for the first time because the vertebrae have given way and because of the results of this giving way, the root of a nerve which gives orders for the functioning of the right hand, then the person has unbearable pain.
In these cases if a person uses the dynamic neck tension relief pillow as a tool in the service of their organism, with the appropriate setting the person increases the horizontal movement which the dynamic neck tension relief pillow creates in order to make it greater than the horizontal movement given by their neck and head, the length of this additional horizontal movement is converted at the time the person lies down on top of the invention to a force which has an opposite direction to the side of our spinal column.
This new force is distributed equally to every vertebra, kept small, is safe, and attempts to push back the vertebrae by exactly the same amount for each one, in a direction opposite to the side of the person's spinal column. Thus if the person uses the dynamic neck tension relief pillow during all the time they lie down to rest or to sleep, with the passage of time the vertebrae stop subsidence, their organism receives an advantage, and the person can feel the attempt to restore the circulation of functions in their members of the throat and neck and of their vertebrae to their natural form, position and functioning.
Putting the dynamic neck tension relief pillow to use as a tool in the service of a person's organism gives them an advantage for their organism but also to the doctor or physical therapist in their attempt to heal the person if the various members which make up the throat and the neck have undergone temporary deformation and not permanent, irreversible deformation.
When a person feels in practice that they have gotten better in their neck but also in their back, they reset it using the setting mechanism and return to the setting at which when they lie down on top of the invention, their neck does not receive any horizontal compression at all, whether stress or pulling.
The person has the possibility to choose the appropriate setting in practice for every case in order to improve as much as possible the health of their neck and throat and the person feels this improvement in practice.
The horizontal force which the dynamic neck tension relief pillow creates when a person has set it and it relieves their neck is lessened a great deal because the sleeping pillow, since it changes shape more easily than the person's neck, absorbs the movement and undergoes temporary deformation. Since however it wants to return to its natural shape it now acts like a spring and transfers to the person's head and neck a small force of attraction or repulsion which for the time space when the person has relieving the neck has the advantage that it is safe.
In addition the length of this horizontal movement which the dynamic neck tension relief pillow creates is small, a person can set it to whatever value they want. It is never transferred by itself, it maintains itself and is always distributed evenly per unit of length to the whole length of the person's neck and of course if the person finishes the process of relieving the neck from compression stress, then the person sets the angle of the sleeping pillow, approximately from 0 degrees to 25 degrees in order to neutralize all the horizontal forces which compress their neck, whether they are compression or pulling and once the person understands in practice how to relieve their neck of all the horizontal forces then at this setting a person can use the dynamic neck tension relief pillow for an indefinite time with complete safety, in order to maintain the improved health of their neck and throat and by extension the quality of their life.

Figure 3a shows a side view of the dynamic neck tension relief pillow Figure 3b shows another side view of the dynamic neck tension relief pillow.
One way of using the invention is described with reference to the figures.
The dynamic neck tension relief pillow consists of a sleeping pillow (8) and a movement mechanism.
The sleeping pillow (8) is any one of the sleeping pillows, without exception, which exist and it does not need any more description because it is well known.
The movement mechanism of the sleeping pillow (8) raises the one of the 4 sides (M) of the sleeping pillow (8), tracing an ascending arc of a circle, while simultaneously giving a length of horizontal movement
The movement mechanism consists of a base (1). On the bottom part of the base (1) there are one or 2 hinges (7). The hinge is connected to the upper level (2) and allows it to move in a half rotation tracing an arc of a circle increasing the angle (n) up to 45 degrees and decreasing the angle (n) down to 0 degrees.
In figure 1 we see that the upper level (2) is connected to the upper side with the elastic attraction rubber (4), said elastic attraction rubber (4) hanging from the support (6) interposing the setting mechanism(3), through the setting mechanism (3) a person stretches or releases the rubber (4) and in this way increases or decreases the angle (n) of the movement mechanism to the degrees desired when it is in default position, with the acute angle (n) the person has the possibility of setting it through the setting mechanism (3) from 45 degrees maximum to 0 degrees minimum when the movement mechanism is in default position.
The descent of the upper level (2) is achieved of course with the load from the weight of a person's head and neck.
In figure 1a we see that the base (1) and the upper level (2) are set to form between them the default position acute angle (n) 20 degrees. In figure 1b they are set to be parallel in the default position and the angle (n) is 0 degrees.
In addition in figure 1b we see that the setting mechanism (3) is suspended on the side of the support (6). The support (6) is pierced and the elastic attraction rubber (4) can be placed inside it and the setting mechanism is to be located where the rubber comes out.
in figure 2 we see another raising component which raises the upper level (2) or the sleeping pillow (8).
This raising component consists of the stable support (6). Inside the stable support (6) is based the mobile support (9), the mobile support (9) is constructed preferably from teflon material or ertalon or any other appropriate material which bends easily.
Inside the stable support (6) is the elastic attraction rubber (4), which is held on the edge of the stable support (6), is based on the bottom part of the mobile support (9) and raises the sleeping pillow (8) by means of the moving support (9) (of course, instead of rubber a helical spring or counterweights can be used), at the point where the elastic atraction rubber (4) comes out of the stable base (6) the setting mechanism (3) is suspended, with the setting mechanism (3) a person can stretch the rubber (4), the upper level (2) is raised more and the acute angle (n) of the sleeping pillow in relation to the mattress is increased.
The maximum value of the angle (n) with the setting mechanism (3) in the default position is 45 degrees and the minimum value of the angle (n) with the setting mechanism (3) in the default position of the movement mechanism is 0 degrees.
This reintroduction component does not show when the dynamic neck tension relief pillow is on top of the bed in the default position because the stable support (6) is under the bed, between the mattress and the bed.
In the perspective of figure 1 we see the holding component (5) which holds the sleeping pillow (8) on top of of the movement mechanism. This holding component (5) is elastic and with preferably two plastic or elastic hooks on the edges or clips.
Figure 2a shows the sleeping pillow (8) in default position with acute angle (n) approximately 45 degrees Figure 2b shows the sleeping pillow (8) with angle (n) approximately 0 degrees.
If with the load of the weight of a person's head and neck or with the setting mechanism (3) a person forces the dynamic neck tension relief pillow to descend down and to trace the length of the arc of a circle from the default angle (n) of 45 degrees shown by figure 4a to the 0 degrees shown by figure 4b, then the sleeping pillow on its upper side and we take the height (I), the height (K), the height (L), we also have the edge of the sleeping pillow (U) and the edge (M). When the sleeping pillow (8), from the default angle (n) of 45 degrees which is shown by figure 4a, descends and becomes horizontal in relation to level (1) or in relation to the mattress, then figure 4b and the angle (n) becomes 0 degrees at point (K) where the height is approximately 50 millimeters, on the upper level it will move (K₁) approximately 35 millimeters of horizontal movement because of its height, to point (L) where the height of the sleeping pillow (8) is approximately 65 millimeters, it will be moved on its upper surface (L₁) approximately 45 millimeters horizontally at point (I), the sleeping pillow will be moved horizontally on its upper surface when it becomes horizontal and comes into a position like that of figure 4b parallel with level (1) because of its height, which is approximately 85 millimeters, it will give a horizontal movement (I₁) of approximately 60 millimeters.
In figure 1c we compare, completely hypothetically, part of a person's spinal column with their head and neck.
We take hypothetically the lengths of 7 vertebrae which are equal to each other (Q, T, Y, F, X, W, V), we have hypothetically raised out head to an angle (n) 22,5 degrees in relation to a person's spinal column, if now the person lowers their neck and head to an angle (n) of 0 degrees then their head and neck come into an exact horizontal line with the imaginary line of their spinal column, measuring now the distances (Y, F, X, W, and V), we see exactly how much is the horizontal length which corresponds to each separate vertebra when it traces the arc of a circle in relation to the imaginary line of the person's spinal column, we have at point (Y) horizontal displacement equal to 2,5 millimeters. At point (F) horizontal displacement equal to 5 millimeters. At point (F) horizontal displacement is equal to 5 millimeters. At point (X) horizontal displacement is equal to 7,5 millimeters. At point (W) horizontal displacement is equal to 10 millimeters. At point (V) horizontal displacement is equal to 12,5 millimeters. We see also that the length of the horizontal movement is distributed equally in 2,5 millimeters to every equal length between the hypothetical vertebrae of the neck along all the length the person's hypothetical neck and hypothetical head, which come into contact with the upper surface of the sleeping pillow (8).
On the contrary, a person can very easily, by means of the setting mechanism (3), set and stabilize the default angle (n) at such an angle that they can use the horizontal movement of the movement mechanism to relieve, with complete safety, all the vertebrae of the neck up to a point in their spinal column of the smallest horizontal compression during our sleep, as we see in figure 1c, Id and 1e.
