Although the bone shapes of the users are different from each other, since the pillow of Patent Document 1 is a general-purpose product for everyone, there is a gap between the user's head and the pillow, and the load on the head (body pressure) However, there is a problem that the portion where the area is affected is biased, the number of times of rolling over is increased, and the user cannot obtain a sufficient rest feeling due to sleep.
Bedding is also required to be made to order.
However, the "made-to-order pillow" currently on the market is said to be a rod-shaped pillow that measures the line on the midline and changes the padding that receives the head along that line. It is classified into several types to more than a dozen types that are biased at the measurement stage, and after roughly determining the height, it is produced at about the scale of the production site, and it cannot be said that it conforms to the user's body shape sufficiently. .

  The present invention has been made in view of such circumstances, and suppresses a portion where a load of a user's head is in close contact with a pillow, body pressure is well dispersed, and stiffness of the shoulder and neck is suppressed. It is an object of the present invention to provide a pillow, a pillow manufacturing method, a pillow manufacturing system, a computer program, and a sleeping posture measuring apparatus that can reduce the number of times of turning over and obtain good sleep.

  The pillow according to the present invention is formed by a 3D printer, and has a shape based on a bone shape of the user including at least a part from the back of the head to the cheeks or a part from the face to the cheeks, and the sleeping posture of the user.

(Description of Embodiments of the Present Invention)
First, embodiments of the present invention will be listed and described. At least a part of the embodiments described below may be arbitrarily combined.

  A pillow according to one aspect of the present invention is formed by a 3D printer, and has a bone shape including at least a portion from the back of the head to the cheeks or a portion from the face to the cheeks of the user, and the sleeping posture of the user. And a support portion that supports the core portion.

Here, in addition to this, "a shape based on the bone shape including at least a part from the back of the head to the cheeks or a part from the face to the cheeks and the sleeping posture of the user" is "sleeping on the neck and shoulders. This means that the “shape at the time of posture” may also be included.
The "shape based on the bone shape and the sleeping posture of the user" is meant to include "the shape of the bone and the meat surrounding it in the sleeping posture".
In this aspect, the core portion formed by the 3D printer has a shape based on the bone shape and the sleeping posture of the user. When the user is in a supine sleeping position, a prone sleeping position, or a sideways sleeping position, the user's head abuts and is fixed, that is, the core part corresponds to the part to which the load is most applied. The head and the pillow are in close contact with each other, the body pressure is well dispersed, there is no discomfort, and the stiffness of the shoulders and neck and the occurrence of headache are suppressed. You can roll over smoothly and do a small number of times to get good sleep.

  In the pillow according to one aspect of the present invention, the core portion has a recess corresponding to the shape, size, and position information of the ear when the user lays sideways.

Here, the recess includes the case where the recess penetrates to the bottom of the pillow.
The ears protrude from the side of the head, and body pressure concentrates on the ears in the sideways lying position. Therefore, the blood flow stops in the ears, the number of times of turning over is increased so that the blood flow is not stopped, and the patient may wake up before and after turning over. It may also cause stiffness in the muscles of the neck or shoulder by taking an uncomfortable posture so as not to crush the ears. In this aspect, since the ears are housed in the recesses corresponding to the shape, size, and position information of the user's ears, and the load on the head side and the cheeks is applied to the parts other than the recesses, the problem is solved. Does not occur. Although there have been pillows that take the ears into consideration, the size, shape, and position of the ears have large differences among individuals, and the above problems cannot be solved because they have not been taken into consideration.

  A method for manufacturing a pillow according to an aspect of the present invention obtains first data relating to a bone shape including at least a portion from the back of the head to the cheeks or a portion from the face to the cheeks of the user, and stores the first data in the first data. Based on this, second data is generated based on the user's supine or lying position and the sideways sleeping position, and a pillow is manufactured using a 3D printer based on the second data.

In this aspect, the first data relating to the bone shape of the user is acquired, the second data based on the sleeping posture of the user is generated based on the first data, and the 3D printer based on the second data. Since the pillow is manufactured by using, the pillow according to the actual sleeping posture of the user can be obtained.
Pillows are manufactured based on the bone shape that includes the part of the user's occipital region to the cheeks (sleeping on his back) or the part from the face to the cheeks (sleeping on his / her face) where the pillow is most loaded at bedtime and the sleeping posture. Therefore, the body of the user and the pillow can be brought into close contact with each other, body pressure is well dispersed, there is no discomfort, and stiffness of the shoulders and neck and headache are suppressed. You can roll over smoothly and get a good sleep with a small number of times.

  In the pillow manufacturing method according to one aspect of the present invention, a core portion based on the second data and a covering portion including an elastic gel having a hardness of 0 to 12 are formed on the supporting portion by using the 3D printer. .

  In this aspect, when using a highly repulsive and hard material for the core portion to shorten the pillow manufacturing time, the pillow is formed by using an elastic gel having a hardness of about human skin, which is also used for artificial limbs orthosis. The surface of can be made to feel soft.

  In the pillow manufacturing method according to an aspect of the present invention, the first data includes data relating to the shape, size, and position information of the user's ear, and has a concave portion corresponding to the data, The core portion is formed.

  In this aspect, the ear is accommodated in the recess corresponding to the shape, size, and position information of the user's ear, and the load on the head side portion and the cheek is applied to the portion other than the recess, so that the load is dispersed. It is possible to reduce the number of unnecessary rollovers that are performed more than necessary. Since the adjustment of each part such as the joints of the body which is distorted while waking up is naturally performed by rolling over, rolling over itself is necessary. However, it is said that rolling over due to obstruction of blood circulation such as ear crushing tends to be useless rolling over because of its different purpose, which causes sleep to be light.

  In the pillow manufacturing method according to the aspect of the present invention, the first data is acquired in a state where the head of the user in the sleeping position is suspended from the trunk.

  When a person is standing, he / she has strength to support the spine, and when he / she is sleeping, he is relaxed and relaxed. different. According to this aspect, since the first data is acquired with the head of the user in the sleeping position floating in the air from the torso, it is possible to manufacture a pillow that matches the shape of the actual sleeping position. When the user measures in the sleeping state, the data of the sleeping posture can be obtained, but even when the measurement is performed in the normal sleeping state, the lower surface cannot be seen from the side and the lower surface shape cannot be measured. In a water bed or the like made of vinyl that can permeate the periphery of the head, the bottom surface shape may be measured from the side, but it is difficult to measure the accurate shape. In addition, the measured data cannot be utilized for sleep improvement because there is a large difference from the normal sleeping posture, for example, the back of the user other than the waterbed user is too depressed.

  A method for manufacturing a pillow according to one aspect of the present invention, based on the first data, a model of the head of the user is produced using the 3D printer, and the model is rolled on an elastic body, Data relating to the user's lying on the back or lying down and lying on the side is acquired.

  In this aspect, the model is rolled on the elastic body so as to reproduce the actual sleeping posture of the user, for example, the angle of the head and shoulders when lying sideways to the left, the curling method, and the like. By rolling the model based on the user's request, it is possible to obtain data relating to the supine sleeping position, the prone sleeping position, and the sideways sleeping position. If there is motion capture data relating to the acquired sleeping posture, this may be used as in the model.

  A pillow manufacturing system according to an aspect of the present invention is an acquisition device that acquires first data related to a bone shape of a user, including at least a part from the back of the head to the cheeks or a part from the face to the cheeks, and the first device. A generating device that generates second data based on the data based on the user's lying-down or lying-down posture and a lateral sleeping posture, and a 3D printer that manufactures a pillow based on the second data.

  In this aspect, the first data relating to the bone shape of the user is acquired face-to-face, the second data is generated, and a part of the pillow is manufactured by the 3D printer. According to the sleeping posture of the user, the user's body and the pillow can be brought into close contact with each other, the body pressure is well dispersed, there is no discomfort, the stiffness of the shoulders and neck and headaches are suppressed, and the person can roll over smoothly and You can manufacture and hand pillows that require less. After completion, it can be corrected and remanufactured on the spot.

  In the pillow manufacturing system according to an aspect of the present invention, the 3D printer creates a model of the head of the user based on the first data, and the generating device rolls the model on an elastic body. The second data is generated based on the moved data.

  In this aspect, the second model is generated by rolling the model on the elastic body so as to reproduce the actual sleeping posture of the user and rolling the model based on the user's request. can do. When there is motion capture data related to the acquired sleeping posture, the model may be rolled based on the data.

  A computer program according to an aspect of the present invention causes a computer to obtain first data relating to a bone shape of a user including at least a portion from the back of the head to the cheeks or a portion from the face to the cheeks, and the first data. The second data is generated based on the user's supine or prone lying position and the sideways lying position, and the process of outputting the second data to the 3D printer is executed.

According to this aspect, a pillow that fits the actual sleeping posture of the user can be obtained.
Since the pillow is manufactured based on the bone shape including the part from the back of the user's head to the cheeks or the part from the face to the cheeks, and the sleeping posture, the head of the user and the pillow can be brought into close contact with each other. The pressure is well dispersed, there is no discomfort, and stiffness in the shoulders and neck and headaches are suppressed. You can roll over smoothly and do a small number of times to get good sleep.

  A sleeping posture measuring apparatus according to an aspect of the present invention includes a frame, a measuring unit including a sheet stretched over an opening surface of the frame, and a supporting unit that supports a human body in a sleeping posture, A part of the human body is opposed to the opening, the other part of the human body is supported by the support part, and the bone shape of the part is measured in a state where the sheet is adjusted along the part.

  In this aspect, since the bone shape that fits the actual sleeping posture of the human body with a relaxed force can be measured, it is possible to manufacture a bedding such as a pillow and a mat that can obtain good sleep.

Hereinafter, the present invention will be specifically described based on the drawings showing the embodiments.
(First embodiment)
1 is a plan view of the pillow 1, FIG. 2 is a sectional view taken along line II-II of FIG. 1, and FIG. 3 is a sectional view taken along line III-III of FIG.
The pillow 1 includes a cover portion 2, a height adjusting portion 3, a support portion 4, a core portion 5, core portions 6 and 6, and a covering portion 7.

The supporting portion 4 contains a synthetic resin material such as urethane having low resilience, has a semicircular shape in plan view, and has a shape recessed from both ends of the string toward the center. The shape of the support portion 4 is not limited to this case.
The support portion 4 has a recess 41 extending in the lateral direction at the center of the pillow 1 in the longitudinal direction, and recesses 43, 43 extending in the lateral direction at both ends in the longitudinal direction.
The cover portion 2 has a plurality of compartments (not shown) for accommodating materials such as urethane chips and flexible polyester pipes. The height of each part of the pillow 1 is adjusted by adjusting the amount of the material contained in the container.
The height adjusting unit 3 is formed by stacking thin urethane layers and adjusts the height.

  The core portion 5 and the core portions 6 and 6 arranged on both sides of the core portion 5 are formed by the 3D printer 13 to be described later so as to fit into the concave portion 41 and the concave portions 43 and 43, respectively. It has a shape based on the bone shape including the part up to the cheeks and the sleeping posture of the user. The sleeping posture includes a supine sleeping posture and left and right lateral sleeping postures.

In FIG. 1, the core portion 5 has a shape based on a supine posture, and the core portion 6 has a shape based on a sideways lying posture.
The core portion 5 has a through hole 51 at a substantially central portion in the longitudinal direction. The support portion 4, the height adjusting portion 3, and the cover portion 2 have a through hole 42, a through hole 31, and a through hole 21 that are continuous with the through hole 51. The case where the through holes 21, 31, 42, 51 are provided is not limited. Instead of providing the through holes 21, 31, 42, the through hole 51 may be replaced by a recess 51 having a bottom surface matching the bottom surface of the recess 43. The through hole 51 or the recessed portion 51 is provided so as to improve air permeability and to make it easier for a person having a different occipital region to obtain the line required for the ankle shoulder, but it is not always necessary. It suffices that the shape of the core portion 5 corresponds to the lying posture on the back.

The core portion 6 further has a through hole 61 corresponding to the shape, size, and position information of the ear when the user lays sideways. Although the through hole 61 is schematically shown in FIG. 1, the through hole 61 is based on the exact shape, size, and position of the ear of each user.
The bone shape data is extracted from the first data acquired by the acquisition device 11 described later for each user. Data concerning the shape, size, and position of the ear is also acquired from the acquisition device 11 for each user.
The through hole 61 preferably has a shape larger than the outer edge portion of the ear of each user by, for example, 0.5 cm to 2 cm. As a result, it is easy to turn over, and the load of the head can be favorably supported by the portion of the core portion 6 other than the through hole 61. It is more preferable that the through hole 61 has a shape larger than the outer edge portion by 1 cm to 1.5 cm.
The support part 4, the height adjusting part 3, and the cover part 2 have a through hole 44, a through hole 32, and a through hole 22 which are continuous with the through hole 61. It should be noted that the through hole 44, the through hole 32, and the through hole 22 may not be provided, and instead of the through hole 61, the recess 61 whose bottom surface matches the bottom surface of the recess 43 may be provided.
Although the core portion 5 and the core portions 6 and 6 are separated in FIG. 1, they may be continuous.

  The data relating to the sleeping posture can be created by reverse engineering software such as 3D CAD software based on the first data. That is, the first data can be rolled to obtain the data. The first data may be acquired by using a sleeping posture measuring device 8 to be described later while the head of the user in the sleeping posture is floating above the trunk. Also, a model including the user's head is produced by the 3D printer 13 to be described later based on the first data, and the model is rolled on an elastic body such as viscosity to set the locus of the sleeping posture on the elastic body. The data relating to the locus may be acquired by the acquisition device 11. Alternatively, the sleeping posture of the user may be measured in advance by motion capture or the like, and the data regarding the sleeping posture may be acquired. The acquisition device 11 may acquire the data regarding the sleeping posture of the user.

  The 3D printer 13 generates the second data for forming the core portions 5, 6, 6 based on the data on the sleeping posture, and the 3D printer 13 outputs the synthetic resin based on the second data to generate the core portion 5. , 6, 6 are formed. Any material can be selected as the synthetic resin. The material may be changed for each of the core parts 5, 6, 6 and for each part of the core part. For example, the core portion 6 corresponding to the lying sideways posture may be made of a material having a higher resilience than that of the core portion 5 corresponding to the lying posture on the back, thereby making it easier to roll over.

  The covering portion 7 includes an elastic gel having a hardness of 0 to 12 and covers a portion of the supporting portion 4 where the core portions 5, 6, 6 are not provided. Even when the core parts 5, 6, 6 are made of a material having high resilience and hardness to shorten the manufacturing time of the pillow, the surface of the pillow 1 can be made soft by using the elastic gel. The core portions 5, 6, 6 may be covered with the covering portion 7.

As shown in FIG. 2, in the central portion of the pillow 1 in the longitudinal direction, the support portion 4 has a shape that approximates to a sleeping posture in a state in which no force is applied, for example, the spine draws a gentle S-shape when lying on the back. . The shape of the support portion 4 is determined in advance based on the bone shape from the head to the shoulders of an average person. The shape is not limited to this.
The support 4 has the recess 41 for receiving the core 5, and the recesses 43, 43. The supporting portion 4 preferably forms an angle between the axis of the head and the horizontal line of 5 to 20 degrees.
The surface of the core portion 5 has a shape corresponding to the shape of the occipital region of the sleeping posture on the back for each user, so that the occipital region of each user and the pillow 1 can be brought into close contact with each other in a portion where a load is applied. The pressure is well dispersed. Therefore, there is no discomfort, and stiffness of the shoulders and neck and headache are suppressed.
The core unit 5 may be loosely fitted to the head of the user based on the acquired bone shape data and data relating to the sleeping posture.

As shown in FIG. 3, at the end portion of the pillow 1 in the longitudinal direction, the support portion 4 has a shape in which the spine is parallel to the bottom surface of the pillow 1, the top surface of the bedding, or both. The shape is not limited to this.
The ears protrude from the side of the head, and the body pressure of the head is concentrated on the ears in the sideways lying position. Therefore, the muscles of the neck or shoulder may become stiff, the blood flow may stop, and the number of times of rolling over may be increased so that the blood flow may not be stopped, and the patient may wake up before and after rolling over. Taking an uncomfortable posture so as not to crush your ears may cause stiffness in the muscles of the neck or shoulders. In the present embodiment, the ear is accommodated in the through hole 61 corresponding to the shape, size, and position information of the user's ear, and corresponds to the shape of the cheek in the sideways sleeping posture of the user other than the through hole 61. This problem does not occur because the parts distribute the load on the head and cheeks. You can smoothly roll over and get good sleep.

FIG. 4 is a block diagram showing the pillow manufacturing system 10 according to the present embodiment.
The pillow manufacturing system 10 serves as an acquisition device 11 that acquires imaging data, and a generation device that extracts the first data and data relating to the shape, size, and position of the ear from the imaging data and generates the second data. PC 12 and a 3D printer 13 that manufactures the pillow 1 based on the second data.
Examples of the acquisition device 11 include a 3D scanner and the like. The acquisition device 11 preferably has two or more cameras or lenses and is capable of simultaneously capturing the upper body of the user from multiple directions at the same time in order to prevent movement or displacement. Although it is possible to take a picture with one unit, if two or more units are used, the photographing time can be shortened. When the user is standing or sitting, take a picture so that the surface shape of the bone at the measurement site appears as accurately as possible by wearing a swimming cap or winding a bandana in order to remove the influence of hair. Preferably. Note that the imaging data is acquired so that the bone shape including at least the part from the back of the head to the cheeks can be extracted, although not limited to the case of imaging the upper half of the user.
It is preferable to acquire not only the head, but also the shapes of the neck bone, shoulder bone, scapula, and hip bone as the first data. The bone of the neck needs to have a shape that fits the S-shaped curve, and in the case of a straight neck, it should have a shape that does not press. If the shoulder bones and hip bones are aligned with the skull and neck bones, it is easier to roll over. Since the step between the scapula and the back of the head corresponds to the height of the pillow 1, it is preferable to measure it.
In the present embodiment, the "shape of bones and meat when sleeping" is acquired without using X-rays. Determine the posture based on the correct sleeping posture, and measure the shape of the bones and surrounding meat based on the posture. At that time, the bone shape can be imaged in the part where the bone shape can be confirmed with the naked eye, but for the user who has the part where the shape cannot be confirmed due to individual differences, the meat and bone shape in that posture will be measured. .

  The PC 12 stores a pillow manufacturing program 123 described later. The PC 12 inputs the imaging data from the acquisition device 11, and the data including the bone including at least the portion from the back of the head to the cheeks of the user, and the shape of the meat surrounding the bone in the sleeping posture, and the shape, size, and Extract position data.

In the case of the first manufacturing method of the pillow 1, the PC 12 uses 3D CAD software or the like to simulate the user's motion based on the bone shape data, and the user's supine or lying down posture and the left and right lateral sleeping postures. Data representing the above is created, and based on this, second data for the 3D printer 13 for creating the core part 5 or 6 is created. Instead of simulating the motion of the user, the user may take a posture and a posture, and as described above, the second data is obtained based on the data regarding the sleeping posture of the user acquired by motion capture or the like. You may decide to create it. In addition, the PC 12 simulates the motion of the user based on the bone shape data and the habit of the sleeping posture of the user (in the case of sideways sleeping, sleeping in a roll) or the motion data based on the user's request. You may decide.
The PC 12 outputs the second data to the 3D printer 13, and the 3D printer 13 creates the core unit 5 or 6 based on the second data.

Hereinafter, in the first manufacturing method, the case where the first data is acquired by the sleeping posture measuring device 8 will be described.
FIG. 5 is a perspective view showing the sleeping posture measuring device 8, and FIG. 6 is a schematic diagram showing a state in which the sleeping posture measuring device 8 is used to acquire the shape of the user's head and the meat surrounding the head in the sleeping posture. is there.
The sleeping posture measuring device 8 supports a user in a sleeping posture, and a measuring unit 84 including a rectangular frame-shaped frame body 82 and a sheet 83 such as a vinyl sheet stretched over the opening surface of the frame body 82. And support portions 81, 81, 81. The frame body 82 is not limited to the rectangular frame, and the support portion 81 is not limited to the box shape. The number of supporting parts 81 is not limited to three. The support portion 81 is arranged so as to correspond to the portion of the user's body to be measured. When the portion to be measured is the head, as shown in FIG. 6, one end side of the support portions 81, 81, 81 in which the measurement portions 84 are arranged in the longitudinal direction so that the head faces the opening of the measurement portion 84. To place. When the portion to be measured is the waist, the measuring unit 84 is arranged so as to face the waist, and the supporting units 81, 81, 81 are arranged so as to sandwich the measuring unit 84 between the supporting units 81, 81.
The outer edge portion of the square sheet 83 is attached to the upper edge portion of the frame body 82 with a string or the like so that the tension can be adjusted. The adjustment using a cord is performed by using a cord stopper or a cord stopper, for example. The sheet 83 may be made of another soft material. The shape of the sheet 83 is not limited to a square shape. It is preferable that the sheet 83 has a small thickness and a bone shape can be recognized well.
The support portion 81 may be prepared, for example, by preparing several kinds of bedding and bed samples used by the user at home in advance and adjusting so that the measurement can be performed in a sleeping posture as close to the house as possible.

As shown in FIG. 6, when the head is opposed to the measurement unit 84, the portion from the shoulder to the crown is projected from the support unit 81 so as to float in the air, and the other parts of the user are supported by the support units 81, 81, 81. Supported by. Then, the bone shape is measured by the acquisition device 11 in a state where the sheet 83 is adjusted so as to follow the bone shape from the head to the base of the neck in the sleeping position. The seat 83 is adjusted by pulling or loosening a string or the like while checking whether it is easy to breathe and whether there is any part that makes you feel uncomfortable or asleep. Is preferred. At the time of measurement, it is necessary to make fine adjustment so that the sheet 83 does not wrinkle in order to obtain a clean shape.
At the time of measurement, the relative height between the support portion 81 and the measurement portion 84 is adjusted. In consideration of the mat and bedding used by the user, when using the manufactured pillow 1, a sleeping posture having a natural curve of the spine that does not apply force is obtained. The height of the measuring unit 84 may be adjusted using a pantograph or the like.

The acquisition of the first data can be performed either in a so-called standing position or a sitting position and in a sleeping position = lying position.
The standing or sitting position makes the measurement very easy. When measuring the shape of the temporal region, the bone shape around the ear, which is particularly important for dispersing body pressure, and similarly for the occipital area, the bone shape from the top of the occipital region to the neck is not clear due to the hair, as described above. It can be measured using a swimming cap or any other item that can hold or put together your hair.
However, as described above, the shapes of human bones and muscles are different between the standing position or sitting position and the lying position.
The reason why the human spine draws a curve is to support the standing posture, and it is a physiological phenomenon to support the body by working the muscle strength.Therefore, measure the depth of the curved portion of the neck in the standing or sitting position, and output it. When reflected in, there is a possibility that a person may feel uncomfortable when sleeping. It is preferable to acquire the first data by using the sleeping posture measuring device 8.

It is known that human beings roll over to control body temperature, recover mental and physical fatigue, improve immune system, organize memory, and repair internal tissues. When the sleeping posture measuring device 8 is used, it is necessary to measure in a posture in which it is easy to roll over.
The posture that makes it easy to roll over is that the head, neck, spine, and hipbone are laid in the case of sideways sleep, and are connected in parallel with the bottom of the bedding in a straight line as much as possible. It has been confirmed by experiments that the head is oriented at a straight line as much as possible with respect to the bottom surface, and the head is oriented at an angle slightly above the straight line, so that the sleeping posture is not difficult.
A test was conducted to find an angle at which it is easy to roll over. When the angle was in the range of 10 to 20 degrees, a comfortable pillow could be provided to all the subjects. After the user takes a sleeping position, it is preferable that the angle is adjusted to a comfortable angle based on the range of 10 to 20 degrees, and then the measurement is performed.
