Description

Detailed Description of the Invention

[Industrial field of application] The present invention can accommodate the height of a pillow (hereinafter referred to as pillow height) in a supine (hereinafter referred to as supine) or sideways (hereinafter referred to as recumbent) sleeping posture, and can be applied to the head. The present invention relates to a sleep pillow that can be superimposed to reduce the applied surface pressure.

[Prior Art] It is well known that many people are not only supine but also recumbent. Conventional pillows are thought of exclusively for the supine position, and few are suitable for lying down. An important requirement of pillows for comfortable sleep is to sleep at a pillow height suitable for both supine and recumbent, and to reduce the surface pressure applied to the head by dispersing it. However, since many conventional pillows have a single structure, it has not been considered to be able to deal with both supine and recumbent as described above. Pillow heights that can be adjusted consciously are described in Japanese Utility Model Publication No. 61-86069 and Japanese Utility Model Publication No. 63-33572, both of which are superimposable, but in both sleeping positions. Is not applicable.

That is, the pillow height is for the mattress,
Taking into account the sinking of the body and the collapsed portion of the pillow, a low pillow (preferably 5 to 8 cm) in the supine position and a shoulder width in the recumbent position add a higher pillow (preferably 9 to 13 cm). ) Is suitable, and it was desired to always maintain a stable height.

However, the above-mentioned publication is not able to do so and has the following problems. That is,
The height changes each time it is used due to movement of the packing, and due to the shape and structure, when the quantity of the packing is large, the shape tends to be rounded. Therefore, both when they are used alone or when they are used in a superposed manner, when the head is placed on them, the state becomes unstable.

And, the change of the pillow height at the time of turning over is
It needs to be simple, fast, and quiet. The pillows mentioned above are not so made. If the height is to be adjusted when turning over, the height is adjusted through a connecting member such as a velcro when superposing or unfolding, and the operation and the sound generated at that time are very troublesome.

Some pillows sold on newspapers have a curved surface with an uneven top surface. In the case of lying down, the surface pressure is large and the support of the head is unstable, and the elasticity is high. There is a drawback that the head becomes sore because of lack of patience, and these are not originally thought to be suitable for recumbency.

[0007] In addition, there is a publicly known one that can be used for recumbency and that adjusts the height by increasing and decreasing air by using a rubber ball type air pump.

On the other hand, the surface pressure of the portion where the filler being used and the head are in contact becomes a problem. That is, the conventional filling material, for example, a granular material, lacks elasticity, and the overall shape of the pillow is not stable. Therefore, it is often rounded at the beginning of use, and the contact area inevitably becomes small, so the surface pressure applied to the head becomes large, pressing that part strongly, and blood circulation worsens and dull pain etc. Was a major factor in awakening, which impeded comfortable sleep. As one of these phenomena, I often experience pain in my ears when I'm lying sideways.

[Problems to be Solved by the Invention] As described above, the conventional pillow is not considered to be adapted to both supine and recumbent postures, and has a shape, a structure, a material and the like. There were various problems.

The present invention is characterized in that the pillow height is adapted not only to the supine position but also to the recumbent position so that each of them has a comfortable natural sleeping posture, and the surface pressure applied to the head is reduced and the head position is reduced. The shape of the center of gravity of the can be stably supported.
By doing so, the spinal nerves distributed in the head, neck, shoulders, chest, arms, etc. will not be compressed, and the blood circulation will be smooth, so that dull pain and seizure will not occur at those parts, frequent rolling and waking up. The purpose is to provide a pillow that allows you to sleep comfortably.

[Means for Solving the Problems] In order to achieve the above object, in the pillow of the present invention, two elastic pillow cylinders each having a leaf spring built therein are provided in two pillow bags. The stored items are pillow (A) and pillow (B), and
The pillow (A) and the pillow (B) are hinged so that they can overlap at the edge of the pillow bag.

[0012] In order to make the pillow height suitable for supine and recumbent, and to obtain a pillow that can stably support the head while reducing the surface pressure applied to the head, the pillow height is approximately supine. -8 cm, 9-13 cm on the recumbent side, and the body has a moderate elasticity and uses a sponge-like foam with little settling.

Further, as shown in FIGS. 1 and 5, the hinged portion of the pillow has an oblique angle from the ridgeline of the hinged portion so that the opposite sides can rotate within a range of about 230 degrees. Also,
The pillow bag is also formed in advance so as to have the same shape as the pillow body. It should be noted that there is no fear of misalignment when superposed, and no means for preventing misalignment is required.

The leaf spring is used for a long time so as not to cause permanent deformation such as bending of the entire pillow, and is attached integrally with the base plate and the main body. It is preferable that the leaf spring is thin, and the entire pillow appropriately bends when it is used, and the deflection is restored when it is not used. In consideration of safety, the size of the leaf spring is smaller than the outer shape of the pillow, and it is attached so that the inner leaf spring is not touched even if the outer periphery is temporarily crushed. Has been.

Further, the base plate is harder than the main body, but has a certain degree of elasticity so that the base plate does not hurt a person even if the pillow hits. The height of the pillows (A, B) cannot be adjusted, so 2 if necessary.
-Three kinds of heights may be considered.

[Operation] In the method of using the pillow configured as described above, one of the pillows (A) is used as shown in FIG. 5 when the person is in the supine position, and as shown in FIG. 6 when the person is in the recumbent position. The pillow (B) is used by being superimposed on the pillow (A). Also, when changing from lying down to lying down, the pillow (B) on the top is unfolded and used only with the pillow (A). And, when it is necessary to wake up and turn over once, it is a feature of this pillow that if you set the pillow height according to the posture, you can fall asleep faster.

It should be noted that although the above-mentioned usage method is basically used, the usage may be reversed according to preference, and
Even if the pillow height is not changed according to the sleeping posture when turning over, there is no particular problem.

In the case of the supine position, the pillow (B) can be expanded within a range of about 230 degrees so as to contact the tatami mat (T) as shown in FIG. 5 in order to stabilize the pillow (A). Then, the above-mentioned change of the pillow height can be performed simply, quickly and quietly.

In this way, the relationship between the sleeping posture and the height of the pillow is in the most favorable state, so that it becomes a natural body which is almost linear from the spine to the cervical spine, and the surface pressure applied to the head can be reduced. By branching from the space, the spinal nerves distributed in the head, neck, shoulders, chest, arms, etc. are no longer pressed, and blood circulation is also smooth at the same time, so that dull pain and crispness do not occur in those parts and comfortable sleep is obtained. To be

[Embodiment] An embodiment will be described with reference to the drawings. (A) In FIG. 1, a steel plate is formed on a base plate (1a) made of polyethylene which is slightly hard and has elasticity. The leaf spring (2a) is attached with an adhesive material, and the main body (3a) made of polyurethane foam having appropriate elasticity is attached with the adhesive material, and further, a special breathable special The ventilation body (4a) formed of urethane foam is attached with an adhesive material. And the one in which these four members are integrated is one pillow body (5a),
Further, the other pillow body (5b) having the same configuration content as above.
Is formed. At this time, one pillow body (5a) is formed slightly thicker. In addition, as the material of the leaf spring, elastic plastics, reinforced plastics containing special fibers, and the like can be considered. (B) In addition to the above (a), a pillow bag for accommodating the pillow body (5a, 5b) is made, and at that time, the edge (7a) of one pillow bag (6a) and the other pillow bag (6b). ) Is sewn together with the end edge (7b) and hinged (8). In addition to the above, fasteners, hooks, velcro, etc. can be considered as the method of attaching the butterfly. (C) Next, one pillow body (5a) is attached to one pillow bag (6a).
By storing a) and the other pillow body (5b) in the other pillow bag (6b), one pillow (A) and the other pillow (B) are set (two pieces are hinged). ) Is completed. In the figure, 9a and 9b are pillow bags (6a and 6b), respectively.
It is a fastener for closing b). (D) One pillow (A) and the other pillow (B) can rotate about the hinged portion (8) within a range of about 230 degrees.

In the embodiment shown in FIG. 1 and FIG. 3, the positional relationship of each member is shown, and the base plate, the main body, and the ventilation body (4a, 4a,
4b) is almost the same size, but the leaf spring is attached 2 cm or more inside the outer circumference of the pillow in consideration of safety.

In the embodiment shown in FIG. 7, the round permanent magnet (10) is bonded by providing a concave seat on the surface of the body (3a, 3b) at a position near the neck.

[Effects of the Invention] Since the present invention is configured as described above, it has the effects described below.

As shown in FIG. 1 and FIG. 2, since the pillow height can be adjusted to supine and recumbent, a comfortable natural sleeping posture is obtained.
Therefore, the extension and compression of the cervical spine are reduced in the supine position, and the chest compression when the heart is placed in the lower left position is released in the recumbent position, and it branches from the intervertebral space to the head, neck, shoulders, chest, arms, etc. The distributed spinal nerves are no longer pressed, and the blood circulation is smoothed at the same time, so that comfortable sleep can be achieved without causing dull pain or crispness in those parts. In particular, in the case of recumbency, the head does not hang down, so that blood does not rise on the head and sleep is improved.

Since the material of the main body and the ventilation member on the upper surface is a sponge-like foam and has an appropriate elasticity, the surface pressure applied to the head becomes small, and even in the case of recumbent, even here, the side surface is used for a long time. The head (especially the ears) does not hurt and the cervical spine is not burdened because it supports the center of gravity of the head. Further, since the ventilator is in the form of a filter, it has good air permeability, and since it is formed so that the amount of sinking is appropriate, it does not get damp.

Since the shape is flat, it has a high degree of freedom and can be easily adapted to various positions and postures. If a permanent magnet is attached to the main body, a magnetic effect around the neck can be obtained.

Furthermore, in the recumbent position, in the case of whiplash, the burden on the cervical spine is reduced, and it also helps prevent snoring.

Further, the following uses are possible. FIG.
It is convenient to use it as a table when reading or writing while sleeping on the bed.
