Abstract

[PROBLEMS] To provide a pillow that during sleep, reduces the load on the cervical vertebrae and lumbar vertebrae. [MEANS FOR SOLVING PROBLEMS] The pillow comprises a bottom face (10) to be placed on a bed and a body mounting face (12) sloping at an angle of about 30° to the bottom face (10). The body mounting face (12) consists of, for example, a flat surface. As the pillow has a depth (A) of about 800 mm, the user (3) can lie on the back with his or her cervical vertebrae and lumbar vertebrae on pelvis stretched. Therefore, the load on the cervical vertebrae and lumbar vertebrae can be reduced.

Description

Pillows and pillow sets

The present invention relates to a pillow and a pillow set that reduce the burden on the cervical spine and bone marrow during sleep and are good for health.

Pillows have a role to lower the blood pressure of the head while keeping the head at a slightly higher position when a person is sleeping.
A conventional normal pillow raises only the head to a height of about 10 cm, and the neck is curved when the pillow is used.
As described above, some pillows support the head, the back of the neck, and the vicinity of the upper shoulder, as well as those supporting only the head as described above.
By supporting the back of the neck and the vicinity of the upper shoulder in this manner, the angle at which the neck bends while sleeping can be reduced compared to a pillow that supports only the head, and the burden on the cervical vertebra near the neck can be reduced.

However, with the conventional pillow described above, the burden on the cervical vertebra near the neck can be reduced, but by placing the head and shoulders at a high position, the spinal cord in the lumbar vertebra above the lumbar part is bent in the abdominal direction. End up.
If the spinal cord is bent in the abdominal direction in this way, it causes back pain.
Here, the lumbar vertebrae are five vertebrae and intervertebral discs arranged on the pelvis and play an important role in supporting the body and protecting the spinal cord (nerves). Therefore, if you continue to live with a burden on the lumbar spine, the possibility of developing diseases such as “lumbar disc herniation” increases.
As described above, the conventional pillows cause problems such as headaches, stiff shoulders, numbness of limbs, back pain and the like, and prevent comfortable sleep. Such a problem makes the intracerebral pressure unstable, such as elderly people and persons with brain diseases, and causes high blood pressure, low blood pressure, and congestion. There are also cosmetic problems.

The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to provide a pillow and a pillow set that can reduce the burden on the spinal cord in the cervical vertebra and lumbar vertebra at bedtime.

In order to solve the above-described problems of the prior art and achieve the above-described object, the pillow of the present invention is a pillow having a substantially triangular cross section, and lies on the floor and on the floor. And a human body placing surface inclined with respect to the floor placing surface so as to support the head from around the waist of the human body. Here, the human body placing surface is inclined with respect to the floor placing surface in a range of 5 to 40 °.

In the pillow of the present invention, not only the head is raised as in the prior art, but the human body placement surface inclined in the range of 5 to 40 ° with respect to the floor placement surface, from the periphery of the waist of the human body lying on its back Support the head.
That is, it inclines from the location which supports a user's waist periphery.
Therefore, the head can be held at a high position without providing a step in the support position around the neck of the user. This allows the user's head to be placed higher than the rest of the cervical spine without bending the cervical vertebra while lying on its back on the pillow, and the burden on the cervical vertebra Can be reduced. Therefore, the effect of preventing headaches and stiff shoulders can be achieved.
In addition, by hold | maintaining a head in a high position in this way, it can suppress that the blood pressure of a head increases, and can suppress that a disorder | damage | failure arises.

Also, the pillow according to the present invention has no step in the support position around the user's waist due to the above configuration, and the waist periphery does not curve. This allows the user's head to be positioned higher than the rest of the bone even when the user is lying on his / her back on the pillow and holding the bone marrow in the lumbar spine straight without bending. Can be reduced. Therefore, the effect of preventing back pain can be achieved.

Also preferably, in the pillow according to the present invention, the length of the floor mounting surface in the direction inclined with respect to the floor mounting surface is about 400 to 1000 mm.

Also preferably, the pillow according to the present invention further includes a mechanism capable of adjusting an angle between the human body placing surface and the floor placing surface.

The pillow set of the present invention includes a first pillow having a substantially triangular cross section and a second pillow superimposed on the first pillow having a substantially triangular cross section.
Here, the first pillow is 5 to 40 ° with respect to the floor placement surface so as to support the head from the floor placement surface placed on the floor and the waist around the human body lying on its back. And a first human body placement surface inclined in the range of.
In addition, the second pillow has a pillow placement surface that is detachably mounted on the first human body placement surface of the first pillow, and a head from the periphery of a human body lying on its back. And a second human body placing surface inclined with respect to the pillow placing surface in a range of 5 to 40 ° so as to support.
By using two pillows in this way, the user can maintain an optimal posture at the time of sleeping and when watching other televisions or the like.

According to the present invention, it is possible to provide a pillow and a pillow set that can reduce the burden on the cervical and lumbar vertebrae at bedtime.

Hereinafter, pillows according to embodiments of the present invention will be described with reference to the drawings.
<First Embodiment>
Drawing 1 is a lineblock diagram of pillow 1 of a 1st embodiment of the present invention. 1A is a side view, FIG. 1B is a plan view, and FIG. 1C is a rear view.

As shown in FIG. 1A, the pillow 1 has a triangular side surface and a depth A of about 900 mm. As long as the back A can support the head from around the waist of the user 3, it can be arbitrarily selected within a range of about 400 to 1000 mm, for example.
Further, the bottom surface 10 is a surface to be placed on the floor, and the body placing surface 12 is inclined with respect to the bottom surface 10 by an angle θ.

The angle θ is, for example, 5 to 40 °, and is preferably about 12 ° from the viewpoint that the burden on the cervical vertebra and the lumbar vertebra is small.
The body mounting surface 12 is a flat surface, for example.
As described above, since the depth A is about 900 mm, the pillow 1 can lie on its back with the user 3 extending the lumbar and cervical vertebrae on the pelvis as shown in FIG.
As the size of the pillow 1, for example, three sizes of large, medium, and small are prepared as shown in FIGS.

As the material of the pillow 1, for example, urethane is used. In addition, as a raw material of the pillow 1, you may use the low resilience urethane etc. as a low resilience material other than normal urethane.

Low-resilience urethane has the property of sinking slowly and returning slowly, ideally enveloping the body. Because of its excellent body pressure dispersion effect, it is also used for medical and nursing care.
Examples of the low resilience urethane include soft urethane foam, semi-rigid urethane foam, and rigid urethane foam.

The degree of resilience of the low resilience material is selected as appropriate. For example, when a material having a relatively high degree of repulsion is used, when the user 3 lies down as shown in FIG.
On the other hand, when a material with a relatively low repulsion degree is used, when the user 3 lies down as shown in FIG.

Further, the pillow 1 may be used by combining a plurality of types of materials. Furthermore, the inside of the pillow 1 may be divided into a plurality of regions, and materials having different regions may be used.

According to the pillow 1 of this embodiment, it inclines from the location which supports the user's 3 waist periphery.
Therefore, the head can be held at a high position without providing a step in the support position around the neck of the user 3. Thus, even when the user 3 is lying on his / her back on the pillow, even if the cervical vertebra is held straight without being bent, the head of the user 3 can be placed at a higher position than the other parts. This burden can be reduced. Therefore, the effect of preventing headaches and stiff shoulders can be achieved.
In addition, by hold | maintaining a head in a high position in this way, it can suppress that the blood pressure of a head increases, and can suppress that a disorder | damage | failure arises.
That is, according to the pillow 1, headaches, stiff shoulders, numbness of limbs, back pain, etc. can be prevented, and a comfortable sleep can be provided. As a result, the intracerebral pressure of elderly people, brain disease patients, and the like can be stabilized, and high blood pressure, low blood pressure, and congestion can be prevented. Furthermore, according to the pillow 1, according to the said structure, there is no level | step difference in the support position of the user 3 periphery of a waist | hip | lumbar part, and a waist | hip | lumbar part periphery does not curve. Thereby, even if the user 3 is lying on his / her back on the pillow, even if the bone marrow in the lumbar spine is held straight without being bent, the head of the user 3 can be placed higher than the other parts. , Can reduce the burden on the bone marrow. Therefore, the effect of preventing back pain can be achieved.

<Modification of First Embodiment>
For example, as shown in FIG. 8, the pillow 1 shown in FIG. 1 may be filled with the low repulsion material 50 on the body placement surface 12 side and filled with the high repulsion material 60 on the bottom surface 10 side.
By doing in this way, in a state where the user 3 lies on the body mounting surface 12 and the inclination angle is kept to some extent by the high repulsion material 60, the low repulsion material 50 causes unevenness along the body shape of the user 3. It is possible to prevent a large force from being applied to a specific part of the body of the user 3. Thereby, the effect of the pillow 1 demonstrated in 1st Embodiment can further be heightened.
Moreover, as the high resilience material 60, for example, an inexpensive material such as polystyrene foam can be used, and the manufacturing cost of the pillow 1 can be reduced.
As shown in FIG. 8, regarding the height of the cross-sectional shape, the low repulsion material 50 is disposed in a region where the height is about half of the height of the high repulsion material 60.

<Second Embodiment>
This embodiment demonstrates the case where the other pillow 31 is piled up on the pillow 1 of 1st Embodiment mentioned above.
FIG. 9 is a configuration diagram of the second embodiment of the present invention. 9A is a side view, FIG. 9B is a plan view, and FIG. 9C is a rear view.

As shown in FIG. 9A, the pillow 31 has a triangular side surface as in the pillow 1.
The bottom surface 30 of the pillow 31 is a surface that is superimposed on the body placement surface 12 of the pillow 1.
There is a body mounting surface 32 that is inclined about 30 ° with respect to the bottom surface 30 of the pillow 31. The angle between the bottom surface 30 and the body placement surface 32 is not particularly limited as long as it is 10 to 40 °.
The body mounting surface 32 is a flat surface, for example.
In the example shown in FIG. 9, the pillow 31 has a shape in which the side surface 35 is integrated with the side surface 15 of the pillow 1 in a state of being superimposed on the pillow 31.

The body mounting surface 12 of the pillow 1 and the bottom surface 30 of the pillow 31 are non-slip surfaces, so that they cannot be easily detached when they are overlapped.
Moreover, you may provide a hook_and_loop | surface fastener (magic tape (trademark)) etc. in the one part area | region of the body mounting surface 12 and the bottom face 30. FIG.

Note that the pillow 1 and the pillow 31 may be sold individually or as a set.

In this embodiment, only the pillow 1 is used at the time of going to bed, and the pillow 31 is superimposed on the pillow 1 when reading other books or watching TV.
Thereby, in each case, while the user 3 takes an appropriate posture, the lumbar vertebra and cervical vertebra above the pelvis can be extended, and the burden on the cervical vertebra and lumbar vertebra can be reduced.
In other words, as in the first embodiment, the user's 3 lumbar vertebra and cervical vertebra can be extended, thereby reducing the burden on the cervical vertebra and lumbar vertebra. Therefore, it is effective for headaches, neck pain, stiff shoulders, low back pain and the like.

<Third Embodiment>
FIG. 11 is a configuration diagram of the third embodiment of the present invention.
As shown in FIG. 11, in this embodiment, two pillows 1 are overlapped.
Thereby, the effect similar to 2nd Embodiment is acquired.

Further, in the second and third embodiments described above, the case where the pillows are stacked in two stages is illustrated, but the pillows may be stacked in three or more stages.

<Fourth embodiment>
FIG. 12 is a block diagram of the fourth embodiment of the present invention.
In the embodiment described above, the case where the inclination of the body placement surface is adjusted by stacking a plurality of pillows is illustrated, but in this embodiment, as shown in FIG. 12, the angle between the bottom surface 10 and the body placement surface 12 Can be adjusted.

As shown in FIG. 12, the bottom surface 10 and the body placing surface 12 are coupled by a hinge 80 or the like so that the angle θ can be adjusted.
Further, the posture of the body mounting surface 12 is maintained at a predetermined angle θ by, for example, the support base 82 placed on the bottom surface 10.
Then, the angle θ can be adjusted by adjusting the position of the support base 82.

According to the pillow of the fourth embodiment, since the angle θ between the bottom surface 10 and the body placement surface 12 can be adjusted, it is not necessary to prepare a plurality of pillows.
In the example shown in FIG. 12, the case where the angle θ between the bottom surface 10 and the body placing surface 12 is made variable by the hinge 80 is exemplified, but the angle θ may be made variable by a mechanism other than the hinge.

The present invention is not limited to the embodiment described above.
That is, those skilled in the art may make various modifications, combinations, subcombinations, and alternatives regarding the components of the above-described embodiments within the technical scope of the present invention or an equivalent scope thereof.

In the above-described embodiment, the case where flat surfaces are used as the body mounting surface 12 of the pillow 1 and the body mounting surface 32 of the pillow 31 is exemplified, but these surfaces may have irregularities.
Moreover, you may have the convex part which supports the back surface of a neck, and the convex part which supports the recessed part of a waist | hip | lumbar.

In the above-described embodiment, the dimensions of each side of each pillow are merely examples, and are not particularly limited as long as the head can be supported from the periphery of the user's waist lying on a general back.

As described above, according to the pillows and pillow sets of all the embodiments described above, the user's 3 lumbar vertebrae and cervical vertebrae can be stretched while keeping the head in a high position, such as at bedtime. Therefore, the burden on the cervical vertebra and the lumbar spine of the user 3 can be reduced, which is effective for headache, neck pain, stiff shoulder, low back pain and the like.

The present invention is applicable to, for example, a pillow used at bedtime.
