Description

  The present invention relates to a pillow used as a bedding, and more particularly to a comfortable pillow excellent in usability.

  Most conventional pillows are cushioned and have an upper surface formed horizontally or nearly horizontally over the entire width. In a state where the back of the head is placed on the pillow and the body is turned upside down (a supine state), the upper surface of the pillow sinks along the shape of the back of the head due to the weight of the head. In addition, even when the head is tilted to the left or right with the body on its back (cervical spine twisted state), the upper surface of the pillow sinks along the shape of the rear part of the temporal head due to the weight of the head, At the same time, even in a state where the body is turned sideways (the lying state), the upper surface of the pillow sinks along the shape of the temporal region due to the weight of the head.

  By the way, in each of the states as described above, a dynamic influence of the pillow on the head occurs. That is, the back head and the temporal region that come into contact with the pillow are pressed against the weight of the head of the pillow by the restoring force of the cushion material constituting the pillow. This compression compresses blood vessels and causes a problem with blood flow. FIG. 16 schematically shows a dynamic influence on the occipital region as an example. The lengths of the arrows a1 to a4 in the figure are indications indicating the magnitude of the restoring force of the cushion material, and are the same as the depth of depression of the cushion material at the position indicated by the arrow. In addition, the broken line A in a figure represents the pillow upper surface position of the state which is not sinking, ie, a horizontal position. According to this guideline, the compression force applied to the cushion material is maximum at the deepest sinking portion, so that the restoring force (arrow a1) at that portion is the largest, and the shallowest sinking portion is the compression applied to the cushion material. Since the force is small, the restoring force (arrow a4) at that portion is also small.

  Therefore, since the upper surface of the conventional pillow is formed horizontally or nearly horizontally, the difference between the restoring force in the deepest sinking portion and the restoring force in the shallowest sinking portion (arrows a1 and (The difference in the length of the arrow a4) becomes larger, so that the restoring force is concentrated locally around the deepest sinking part. This phenomenon causes poor circulation and discomfort. It will be unbearable and you will have to continually roll over.

  In addition, as described above, since the upper surface of the pillow sinks along the shape of the head due to the weight of the head, the sinked head and the pillow are always in close contact with each other. In such a conventional pillow, when the head is tilted to the left or right, that is, when the cervical spine is twisted, the restoring force of the pillow is concentrated near the ears of the body, and the ears are in close contact with the upper surface of the pillow. , Feels pressure on the ears, and when the temperature is high, the ears may be hot or sweating, and it may cause difficulty in sleeping, and the ears of the body become unsanitary due to sweating Sometimes.

  Furthermore, in the conventional pillow, when the head is turned over 90 degrees, that is, in the lying state, the cheeks are in close contact with the upper surface of the pillow, so that the cheek feels pressure and the bed is lying on the cheeks If the temperature is high, the cheeks may be hot or sweating, and it will cause you to feel uncomfortable and cause you to lie down. In addition, as shown by a broken line C in FIG. 17, when the body is lying down, the body torso is almost perpendicular to the floor, so that the position of the neck increases by the shoulder width, whereas the jaw Since the width of the jaw is narrower than the width of the head and the width of the head, the head is inclined upward from the jaw to the head. Therefore, when using a conventional pillow, in the lying state, the neck is lowered from the position of the horizontal spine toward the neck, and rises from the cervical spine toward the head. Such an unnatural posture may cause stiff shoulders and cause sleeping errors.

  Furthermore, in such a conventional pillow, when the body neck is placed on the upper surface on the near side of the pillow in the supine state, the neck is positioned above the torso more than necessary by the height of the pillow. In other words, an excessive bending force is applied to the cervical spine of the neck, which may cause whiplash and myelopathy of the neck.

  As described above, the conventional pillow has been compressed and recessed according to the weight of the head, neck and shoulders of the body due to the elasticity of the material constituting the pillow. In order to make the head, neck and shoulders at just the right angles, the upper surface of the pillow is inclined in advance and the depressions and bulges are formed so that the pressure applied to the head, neck and ears is reduced. The pillow is designed to be evenly distributed at any angle, such as upward or sideways, without forcibly pressing the head, ears, cheeks, cervical vertebrae, and shoulders. An object of the present invention is to provide a comfortable pillow that has an excellent feeling of use that does not cause pain to the mind and body even when used for a long time.

  The comfort pillow according to the present invention forms an uneven surface on the upper surface of the pillow in accordance with the uneven shape of the bulge of the back of the body, the constriction of the neck of the body, and the thickness of the shoulder of the body, and the head of the body An inclined surface is formed so as to incline downward from the tip toward the neck of the body. By comprising in this way, the compression force which a pillow exerts on a body is reduced, a feeling of floating is felt, and sleeping comfort is improved.

  As a specific configuration therefor, the comfort pillow according to the present invention is a pillow whose pillow upper surface is inclined downward from the back side to the front side of the pillow, and is located at the center of the pillow upper surface. A dent for placing the back of the head is formed at a position where the abutment comes into contact.

  In addition to the above configuration, when the back of the body is placed on the back of the head for placing the head on both sides of the back of the top of the pillow, the body is tilted left and right. The ear placement recess may be formed at a position that is inclined and stabilized along the concave and convex shapes of the face side surface, the body head side surface, and the body neck side surface.

  As described above, the comfort pillow according to the present invention is configured so that the upper surface of the pillow is inclined downward from the back side to the front side of the pillow, so when this pillow is used to enter the supine state In a state where the body tilts slightly downward from the head to the neck, in other words, the body torso is almost horizontal, slightly bent at the neck, and slightly tilted from the neck to the head tip It becomes a posture. From the ergonomic point of view, this posture is said to be the most stable optimal posture with less burden on the body in the supine state, and if the comfortable pillow according to the present invention is used, this optimal posture can be taken naturally. This makes it a very comfortable pillow.

  Moreover, the mechanical influence which a pillow exerts on a back head or a cheek part is relieve | moderated by forming the hollow part for occipital head placement and the hollow part for ear | edge part mounting as mentioned above. As an example, FIG. 15 shows the mechanical influence of a pillow on the back of the head. The lengths of the arrows b1 to b4 in the figure are indications indicating the magnitude of the restoring force of the cushion material, and are the same as the depth of depression of the cushion material at the position indicated by the arrow. In addition, the broken line B in a figure represents the pillow upper surface position of the state which is not sinking, ie, the upper surface position of a hollow part. According to this guideline, the compressive force applied to the cushion material is maximum at the deepest sinking portion, and even if the restoring force (arrow b1) at that portion is the largest, the recess is provided in advance. It is proved that the restoring force is greatly reduced as compared with FIG. Since the compressive force applied to the cushion material is small in the shallow submerged portion, the restoring force (arrow b4) in that portion is also small.

  As shown in FIG. 15, the difference between the restoring force in the deepest sinking portion and the restoring force in the shallowest sinking portion (the difference in length between the arrows b1 and b4) is small. The restoring force of the cushioning material against is dispersed and the pressure on the head is relieved. Therefore, the poor circulation and discomfort to the head of a conventional pillow can be resolved, and it is comfortable even if the pillow is used for a long time in a supine, cervical spine or lying position. It will not make you feel any pain.

  In addition, since the ear mounting recess is provided, there is a slight gap between the upper surface of the pillow and the ears and cheeks, so that it is possible to prevent the ears and cheeks from being completely adhered to the upper surface of the pillow, Since there is no feeling of pressure on the ears and cheeks, a comfortable feeling of use can be obtained, and the ears and cheeks can be prevented from burning or sweating, so that they can be used more comfortably.

  Furthermore, in addition to the above-described configuration, the jaw of the body in which the inclination of the pillow is increased by approximately the shoulder width of one side of the body in the lying state, on both sides of the upper surface of the pillow, on the outer lower side of the ear mounting depression. You may form and form the ridge part for jaw part mounting for mounting a part.

  With the above configuration, when the head rolls over and becomes a recumbent state, even if the body rolls over and the position of the neck is raised, the jaw of the body is placed on the ridge for placing the jaw Since it is supported stably at the height of the neck, the horizontal state can be maintained from the head of the body to the chin. Therefore, since it becomes a substantially horizontal state from the spine to the head, an easy posture can be maintained. In addition, the face, chin, neck, and head of the body come into contact with the ridges for placing the chin, thereby making it feel as if the infant is sleeping in the mother's chest.

  Furthermore, in addition to the above-described configuration, an inclined surface that descends outward is formed at a portion where the shoulder abuts on the upper surface on the front side of the pillow, and the occipital portion mounting depression at the center of the inclined surface A cervical vertebra placement ridge may be formed at a position where the cervical vertebra of the body abuts on the near side.

  With this configuration, in the supine state, the occipital region of the body is placed and positioned in the occipital region mounting depression, and the contact area between the shoulder portion of the body and the pillow is widened by the inclined surface, so that the body The cervical vertebra mounting portion is in a very stable state, with the cervical vertebra being a constricted portion on the back of the cervical portion contacting the cervical vertebra, which is a constricted portion. Therefore, even if the supine state is continued for a long time, there is an advantage that there is little burden on the body and it is possible to spend comfortably.

  According to the comfort pillow according to the present invention described above, all the disadvantages of the conventional pillow can be eliminated, the head, cheeks, cervical vertebrae, shoulders, etc. are not forcedly pressed, and even when used for a long time. It is possible to provide a comfortable pillow with excellent usability that does not cause physical and mental pain. In addition, in the configuration of the comfortable pillow according to the present invention, the inclination angle of the pillow upper surface, the occipital portion mounting recess, the ear mounting recess, the chin mounting protuberance, and the cervical vertebra mounting protuberance are used. If designed according to the body shape of each person, a custom-made comfortable pillow that is optimal for the user can be provided.

  Hereinafter, preferred embodiments of a comfort pillow according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view of a comfort pillow according to the present embodiment, FIG. 2 is a plan view of the comfort pillow according to the present embodiment, FIG. 3 is a cross-sectional view taken along line AA in FIG. 2 is a cross-sectional view taken along line B-B in FIG. 2, FIG. 5 is a cross-sectional view taken along line CC in FIG. 2, and FIG. 6 is a schematic plan view illustrating a use state in the supine state of the comfort pillow according to the present embodiment. 7 is a schematic longitudinal sectional view of FIG. 6, FIG. 8 is a schematic transverse sectional view of FIG. 6, and FIG. 9 is a schematic plan view showing a usage state of the comfortable pillow according to the present embodiment in the cervical spine state. 10 is a schematic longitudinal sectional view of FIG. 9, FIG. 11 is a schematic transverse sectional view of FIG. 9, and FIG. 12 is a schematic plan view showing a use state of the comfortable pillow according to the present embodiment in a lying state. 13 is a schematic longitudinal sectional view of FIG. 12, and FIG. 14 is a schematic transverse sectional view of FIG.

  1 and 2, reference numeral 10 denotes a pillow according to the present embodiment. The pillow 10 is made of polyurethane foam, and is usually used by being covered with a covering cloth. The overall shape of the pillow 10 is such that the upper surface of the pillow is inclined downward from the back side 10a to the front side 10b of the pillow as shown in FIGS. Since the pillow 10 according to the present embodiment is configured in such a shape, when this pillow is used to enter a supine state, the head is tilted slightly downward from the head to the neck as shown in FIG. In other words, the body torso is almost horizontal, slightly bent at the neck, and tilted so that the head slightly lifts from the neck to the tip of the head. This posture is the optimum posture as described above, and if this pillow 10 is used, this optimum posture can be taken naturally, so that the pillow is extremely comfortable to sleep.

  On the upper surface of the pillow 10, a occipital portion mounting recess 20 is formed at the center thereof, and the peripheral wall portion 22 of the occipital portion mounting recess 20 expands upward as shown in FIGS. 3 and 5. As shown in FIGS. 6 to 8, the occipital region of the body fits in well and stably supports the occipital region. In particular, as shown in FIG. 7, the peripheral wall 22a on the near side is a portion that abuts on the constricted portion between the occipital region and the cervical vertebra, so that it is formed on a steep slope to ensure stability, and conversely, the peripheral wall 22b on the back is shown in FIG. As shown in FIG. 7, it is a portion that abuts on the gentle curved surface on the front end side of the occipital region. By providing the occipital portion placement recess 20, as described above, the mechanical influence of the pillow 10 on the occipital region of the body is alleviated. In other words, by providing the occipital portion placement recess 20, the amount of sinking of the cushion material is reduced by the depth of depression when the occipital region is placed in the occipital placement recess 20. The force that the cushion material tries to restore is reduced. On the other hand, since the peripheral wall portion 22 having a shallow sinking has a small compressive force applied to the cushion material, the restoring force of the cushion material is also small. Therefore, the restoring force of the cushion material on the back of the head is almost evenly distributed, and the pressure on the back of the head is relieved. Therefore, poor blood circulation or discomfort to the back of the head does not occur, and the patient can easily withstand long-term use in the supine posture.

  As shown in FIG. 1 and FIG. 2, ear placement dents 30 are formed on both sides of the occipital placement dent 20 on the upper surface of the pillow 10. The ear mounting recess 30 is formed at the left and right positions in the vicinity of the abutment of the ear when the back of the body is placed on the back head mounting recess 20 and the head of the body is tilted left and right. It is a thing. As shown in FIGS. 4 and 5, the ear placement recess 30 has a peripheral wall portion 32 that is an inclined surface that expands upward, as shown in FIGS. 9 to 11. It fits well and supports the rear part of the body's temporal head stably. In particular, as shown in FIG. 11, the inner peripheral wall portion 32a is a portion that comes into contact with the side surface of the rear portion of the temporal region, so that it is formed on a steep slope to ensure stability. On the contrary, the outer peripheral wall portion 32b is a portion that comes into contact with the cheek portion side, so that it is formed on a gentle slope as shown in FIG. By providing the ear mounting recess 30, as described above, the mechanical influence of the pillow 10 on the head of the body is alleviated. That is, by providing the ear placement recess 30, when the body ear is placed in the ear placement recess 30, the cushion material sinks by the depth of depression in advance. Since the amount decreases, the force that the cushion material tries to restore decreases. On the other hand, since the peripheral wall portion 32 having a shallow sinking has a small compressive force on the cushion material, the restoring force of the cushion material is also small. Therefore, the restoring force of the cushion material on the ear part and its periphery is distributed almost evenly, and the pressure on the ear part and its periphery is relieved. Therefore, poor blood circulation and discomfort to the ear and its surroundings do not occur, and it can easily endure in a comfortable state for a long time use in the cervical spine posture.

  In addition, since the ear placement recess 30 is provided, as shown in FIGS. 10 and 11, the upper surface of the pillow (in this case, the central portion 34 of the ear placement recess) and the ear Since there is a slight gap between it and the cheeks, it is possible to prevent the ears and cheeks from coming into close contact with the upper surface of the pillow. Since it can prevent sweating, it can be used more comfortably.

  In the pillow 10 in the present embodiment, a ridge portion 40 is formed at the lower part on the outer side of the ear placement recess 30. The jaw bulging portion 40 further rolls the head from the cervical spine twisted state shown in FIGS. 9 to 11 and turns sideways as shown in FIGS. 12 and FIG. 13, the jaw of the body is placed on the jaw raised portion 40, so that the horizontal state can be maintained from the head of the body to the jaw as shown in FIG. 13. Therefore, since it becomes a substantially horizontal state from the spine to the head, an easy posture can be maintained.

  Further, in the pillow 10 in the present embodiment, a front head raised portion 50 is formed at the upper portion on the outer side of the ear portion mounting recess 30. The forehead bulging portion 50 serves to stop the movement of the head of the body and to support and stabilize the forehead as shown in FIGS. 12 and 13. Together, the head further rolls over and moves horizontally, preventing the head from coming off the pillow.

  Furthermore, the pillow 10 according to the present embodiment forms an inclined surface 60 that descends outward at the portion of the front surface of the pillow 10 that comes into contact with the shoulder from the neck of the body as shown in FIGS. 1 and 3. The cervical vertebra placement ridge 70 is formed at a position where the cervical vertebra of the body abuts on the front side of the occipital portion placement recess 20 at the center of the inclined surface.

  With this configuration, in the supine state, the occipital region of the body is placed and positioned in the occipital region mounting recess 20, and the contact area between the shoulder portion of the body and the pillow is widened by the inclined surface 60. Therefore, it smoothly descends along the shape of the body from the neck to the shoulder of the body, and furthermore, the cervical vertebrae which is the constricted portion on the back of the neck is in contact with the raised portion 70 for placing the cervical vertebrae, and is in an extremely stable state It becomes. Therefore, even if the supine state is continued for a long time, there is an advantage that there is little burden on the body and it is possible to spend comfortably.

  In the above embodiment, the pillow 10 is made of polyurethane foam. However, the pillow 10 is not limited to this, and it can be filled with buckwheat husks and pipes as long as the feature of the present invention can be maintained. It may be a pillow.

  Moreover, in said Example, as the pillow 10, the dent 20 for occipital head placement, the dent part 30 for ear | edge part placement, the ridge part 40 of a chin part, the front part bulge part 50, the inclined surface 60, and cervical vertebra placement Although the thing provided with all the protruding parts 70 for a pillow was shown, the pillow of the structure provided only with the dent 20 for occipital head mounting, and the dent part 30 for an ear | edge part mounting, the protruding part for a chin part on the dent 20 for mounting an occipital region It is good also as a pillow provided with any one or some structure of the part 40, the frontal part protruding part 50, the inclined surface 60, or the protruding part 70 for cervical vertebrae placement.
