Description

  The present invention relates to pillows and pillow systems.

2. Description of the Related Art A pillow provided with a bag that expands and contracts with air has been proposed for the purpose of improving a user's sleeping posture and responding to individual differences.
For example, Patent Literature 1 discloses a pillow sheet in which a number of air bags (chambers) are arranged. The expansion and contraction of each chamber is controlled by a control module.

  Also, for example, Patent Document 2 discloses a pillow having two-stage air bags (air bags). The two-stage air bag is configured such that the lower air bag inclines the upper air bag, so that a large amount of air can be generated with a small amount of air.

JP 2007-283106 A JP 2006-101934 A

However, it is difficult for a single-stage air bag to cause a large deformation on the pillow enough to improve the sleeping posture of the user. Further, even if air bags are stacked in a plurality of stages, in the related art, the lower air bag simply lifts or tilts the entire upper air bag or the pillow, and does not contribute to the deformation of the pillow.
In view of the above circumstances, an object of the present invention is to provide a pillow and a pillow system using an air bag to obtain a large deformation that improves a user's sleeping posture.

  A pillow that achieves the above object has at least an upper surface, an upper bag made of a material that expands and contracts with the inflow and outflow of air, and a material that is arranged below the upper bag, and has at least an upper surface that expands and contracts with the inflow and outflow of air And the lower bag is disposed between the upper bag and the lower bag, and the lower surface of the upper bag is fixed or doubles as the lower surface. A flexible sheet that is hard enough not to be wrinkled even when the bag is deflated, and that is flexible enough to be bent by the force of expansion and contraction of the lower bag.

  According to such a pillow, since the expansion and contraction of the lower bag contributes to the deformation of the pillow through the flexure of the flexible sheet, it is possible to cause a sufficiently large deformation of the pillow between the upper bag and the lower bag. it can. Further, since the flexible sheet has the above hardness, the force due to the expansion of the upper bag is prevented from escaping to the side, and the pillow is efficiently deformed in the vertical direction by the expansion and contraction of the upper bag.

  In the pillow, the flexible sheet has at least one end extending around the side of the lower bag and extending to below the lower bag, and the one end is held so as not to come off to the side. Is preferred.

  According to such a preferable configuration, the warp of the flexible sheet when the upper bag is inflated is suppressed by the one end of the lower bag that is wrapped around the side, so that the pillow is vertically deformed due to the expansion and contraction of the upper bag. Is more efficient.

  In a pillow in which one end of the flexible sheet is wrapped around the side of the lower bag, the flexible sheet has one end in the front, rear, left and right directions perpendicular to the vertical direction in which the upper bag and the lower bag overlap. It is further preferable that the lower bag is held around the lower bag by wrapping around the side in each direction. With such a configuration, the warp of the flexible sheet is suppressed in all of the front, rear, left, and right directions.

  Further, in a pillow in which one end of the flexible sheet is wrapped around the side of the lower bag, of the one end of the flexible sheet, one end located on the neck side of a person who puts a head on the pillow It is also preferable that a part in the left-right direction of a portion which goes around the side of the lower bag is recessed toward the lower bag. Since the part of the flexible sheet is recessed in this way, the fit between the pillow and the neck of the user is increased.

  Further, in a pillow in which one end of the flexible sheet is wrapped around the side of the lower bag, a part of the flexible sheet which wraps around the side of the lower bag is provided with the flexible sheet. It is also preferable that a hole for enhancing the flexibility of the flexible sheet is provided. By forming such holes, the height of the pillow when the air bag is deflated is sufficiently reduced, so that it is possible to widely respond to the user's preference for height.

  In the pillow, it is preferable that a plurality of lower bags arranged along the flexible sheet be provided as the lower bags. By providing a plurality of lower bags, the number of types of deformation caused by expansion and contraction of the lower bags is increased as compared with the case of one lower bag.

  In a pillow provided with a plurality of lower bags, it is further preferable to provide, as the lower bags, a plurality of lower bags arranged on the left, the middle, and the right in the left-right direction. A particularly useful variant is obtained with the left, middle and right arrangement.

  In a pillow including left, middle, and right lower bags, it is still more preferable that the flexible sheet has a fold extending between the plurality of lower bags. The fold facilitates the useful deformation.

  Further, in the pillow including a plurality of lower bags, it is preferable that the upper bag includes a plurality of upper bags arranged along the flexible sheet. By providing a plurality of upper bags, the number of types of deformation caused by expansion and contraction of the upper bags is increased as compared with the case of one upper bag.

A pillow system that achieves the above object includes a pillow that is deformed by sending air, an air feeding device that sends air to the pillow, and a control device that controls the sending of air by the air feeding device. At least the upper surface, an upper bag made of a material that expands and contracts with the inflow and outflow of air, and a lower bag that is disposed below the upper bag and at least the upper surface is made of a material that expands and contracts with the inflow and outflow of air, It is arranged between the upper bag and the lower bag, and the lower surface of the upper bag is fixed or doubles as the lower surface. A flexible sheet that is hard enough to be less than wrinkles and has flexibility enough to be bent by the force of expansion and contraction of the lower bag.
According to such a pillow system, a sufficiently large deformation can be caused in the pillow between the upper bag and the lower bag, and the pillow is efficiently deformed in the vertical direction by expansion and contraction of the upper bag.

  ADVANTAGE OF THE INVENTION According to the pillow and pillow system of this invention, the big deformation | transformation which improves a user's sleeping posture is obtained.

FIG. 11 is a diagram illustrating an embodiment of a pillow system.

  The pillow system 1000 includes the pillow 100 of the first embodiment described above and a control box 200, and the control box 200 can communicate with the smartphone 300.

  The control box 200 has an air pump 33 and an air control valve 32 built therein. The air control valve 32 switches between injection and discharge, and the air pump 33 performs injection and discharge of air. The air supply device including the air pump 33 and the air control valve 32 can individually inject and discharge air for each of a total of ten airbags provided in the pillow 100. In addition, the air supply device according to the present embodiment also incorporates a flow meter that measures the amount of air injected and the amount of air discharged.

The control box 200 includes a power switch 31, an AC adapter 34, and a remote controller 35, and a control board 30 is housed inside. The control board 30 controls injection and discharge of air by an air supply device including an air pump 33 and an air control valve 32. Further, the control board 30 can store the amount of air injected into and discharged from each airbag, and can change the amount of air in each airbag and then return the air to the original amount. The control board 30 controls the manual mode for controlling the injection and discharge of air according to the operation of the remote controller 35, and controls the injection and discharge of air according to the detection by the pressure sensor 17 and the voice sensor 18 provided on the pillow 100. It has an auto mode. In addition, the control board 30 can display the state of the system via the smartphone 300 and receive a setting operation.
FIG. 12 is a diagram illustrating an operation unit of the control box 200.

On the outer surface of the control box 200, a power switch 31, an input key 39, and a liquid crystal display 40 are provided. The input key 39 is used for various settings such as an alarm setting, and the setting state is displayed on the liquid crystal display 40.
FIG. 13 is a diagram illustrating an operation unit of the remote controller 35.

  On the outer surface of the remote controller 35, up, down, left and right operation keys 37, six LEDs 38a corresponding to the six airbags 4a,..., 4f provided on the upper base 1 of the pillow 100, and a lower base of the pillow 100 The four LEDs 38b corresponding to the four airbags 5a,.

When one of the ten LEDs 38a and 38b is turned on, one airbag selected as a target for injecting and discharging air is indicated. The airbags to be selected are switched one by one in a specific order by operating the left and right keys of the operation keys 37.
By operating the up and down keys of the operation keys 37, air is injected and discharged into the selected airbag.

FIG. 14 to FIG. 16 are diagrams for explaining the action caused by the inflation of the airbag. FIG. 14 shows a state before the airbag is inflated, FIG. 15 shows a state where the airbag is inflated, and FIG. 16 shows a warpage of the sheet substrate 3 caused by the inflation of the airbag. Have been.
Here, as an example, an operation when the fifth airbag 4e of the upper base 1 is inflated is shown.

  When air is injected into the airbag 4e, the airbag 4e inflates upward. Although the airbag 4e is shown in the shape of a prism in the figure, in practice, the upper surface of the airbag 4e expands smoothly, so that the airbag 4e expands round. Further, while the upper surface of the airbag 4e is inflated, the sheet base material 3 on the bottom surface of the airbag 4e does not expand, so that the escape of inflation in the direction along the sheet base material 3 is suppressed, and the airbag 4e is inflated. Inflates efficiently upward. As a result, the pillow 100 undergoes a large deformation.

By inflating the airbag 4e in this manner, as shown in FIG. 15, the airbag 4e generates a force f1 in the direction of lifting the user's head. In particular, when the user's head rests on the pillow 100, a downward reaction force f2 is generated with respect to the force f1. The reaction force f2 acts to dent the portion of the sheet substrate 3 corresponding to the bottom of the airbag 4e downward. As a result, when the base member 6 is not provided, a force f3 for lifting the sheet base member 3 around the airbag 4e is generated due to the depression at the bottom of the airbag 4e. By such a force f3, as shown in FIG. 16, the sheet base material 3 is lifted up. When the sheet substrate 3 is lifted (warped) in this manner, the pillow 100 is distorted, and the sleeping comfort is deteriorated.
Therefore, in the present embodiment, the base member 6 is attached to the back side of the sheet member 3.
FIG. 17 is a diagram illustrating the operation of the base member 6.

  When the base material 6 is attached to the back side of the sheet material 3, the dent at the bottom of the airbag 4 e due to the reaction force f <b> 2 against the upward force f <b> 1 of the airbag 4 e is suppressed by the base material 6. Therefore, the force f3 for lifting the periphery of the airbag 4e is also suppressed, and the pillow 100 is prevented from being distorted.

Even when the base material 6 is attached, the entire base material including the sheet material 3 and the base material 6 can be bent to a degree that the airbag of the lower base 2 deflects. It has flexibility.
Lifting (warping) of the sheet substrate 3 described above is also suppressed by the projecting pieces 3a, 3b, 3c, 3d of the sheet substrate 3.
FIG. 18 and FIG. 19 are diagrams for explaining the operation of the projecting pieces 3a, 3b, 3c, 3d of the sheet base material 3. FIG. FIG. 18 is a perspective view, and FIG. 19 is a top view.

The projecting pieces 3a, 3b, 3c, 3d of the sheet base 3 suppress the lifting of the sheet base 3, as indicated by arrows in the figure. As a result, even when an airbag (for example, the fourth airbag 4d or the fifth airbag 4e) near the end or corner of the pillow 100 is inflated, unnecessary distortion of the pillow 100 is suppressed, and the airbag The bulging forces of 4d and 4e are efficiently generated in the upward direction.
In the pillow 100 of the present embodiment, the bend structure described below improves the sleeping comfort.

  20 to 22 are views showing a bending structure. FIG. 20 shows the bending of the upper base 1, FIG. 21 shows the bending of the lower base 2, and FIG. 22 shows the bending of the entire pillow 100.

  As described above, the airbags 4a,..., 4f of the upper base 1 are provided in three rows of right, middle, and left, and the sheet base material 3 is provided with folds VF between the rows. I have. Further, the sheet base 3 of the lower base 2 is also provided with folds VF between the three rows of right, middle, and left.

  Since such a fold VF is attached to the sheet substrate 3, the pillow 100 is easily broken at the fold, and has a bent structure that bends inward as indicated by the arrow in FIG.

  FIG. 23 and FIG. 24 are diagrams illustrating the operation of the bending structure. FIG. 23 shows a state where there is no bent structure, and FIG. 24 shows a state where there is a bent structure. FIGS. 23 and 24 schematically show the state as viewed from the rear side of the pillow.

  If there is no bent structure, the distance d between the rows of the airbags 4a,..., 4f arranged in a plurality of rows is large, and when the user 400 puts his / her head on the head, the user feels a groove, which hinders sleeping comfort. I do. On the other hand, when there is a bent structure, the distance d between the rows of the airbags 4a,..., 4f is reduced, so that the user 400 is less likely to feel the groove and the sleeping comfort is improved. Such a folding structure is not an essential structure in the pillow of the present invention, but the adoption of the folding structure improves the sleeping comfort.

  Next, a procedure for setting the height of the pillow 100 to match the height of the pillow 100 with the body type of each user will be described. This height setting is performed in the manual mode described above.

In the height setting, the user sets the height by adjusting the air amount of the airbag while sequentially changing the posture between the supine posture and the left and right lying postures. Here, as an example, a description will be given below assuming that the first height setting is performed in the supine posture, the second height setting is performed in the right-side lying posture, and the third height setting is performed in the left-side lying posture. .
FIG. 25 is a diagram showing the height to be adjusted by setting the height of the supine posture.

  When the user 400 places the head on the pillow 100 in the supine position, the height of the pillow 100 is, for example, a height difference T1 between the lowest point of the back and the back of the head, and the lowest point of the back and the back of the neck. It is said that the height that compensates for the height difference T2 with the height is appropriate. However, in the actual adjustment, the adjustment is such that the height difference T1 and T2, the amount by which the pillow 100 sinks into the bed or the futon, and the preference of the user 400 are reflected.

  FIG. 26 is a diagram illustrating a state of the airbag before adjustment in the height setting of the supine posture. FIG. 26A is a cross-sectional view, and FIG. 26B is a layout view of an airbag.

  Before the adjustment of the height setting, all the airbags are deflated, and the height of each airbag is the lowest as shown in FIG. In FIG. 26 (B), all the airbags of the upper base 1 and the lower base 2 have a white display indicating that there is no air.

  FIG. 27 is a diagram illustrating the state of the airbag after adjustment by setting the height of the supine posture. FIG. 27A is a cross-sectional view, and FIG. 27B is a layout view of an airbag.

In the adjustment of the height setting, the user 400 operates the above-described remote controller 35 to inject air into the airbags 4c and 4d provided in the central row of the upper base 1. Then, the user 400 adjusts the air amount so that each of the airbags 4c and 4d reaches an appropriate height (a desired height) as shown in FIG. As a result of such adjustment, the airbags 4c and 4d provided in the central row of the upper base 1 are inflated, as shown by hatching in FIG.
FIG. 28 is a diagram illustrating the height to be adjusted by setting the height of the right-side-down lying posture.

When the user 400 puts his / her head on the pillow 100 in the lying posture, the height of the pillow 100 is, for example, the height difference T3 between the lowest point of the shoulder and the temporal region, and the lowest point of the shoulder. It is said that a height that compensates for the height difference T4 from the side of the neck is appropriate. However, the actual adjustment is an adjustment that reflects such a height difference T3, T4, the amount by which the pillow 100 sinks into a bed or a futon, and the preference of the user 400.
FIG. 29 is a diagram illustrating a state of the airbag before adjustment in the height setting of the right-side lying posture.

Before the adjustment in the right-sided lying posture, all the other airbags are the cross-sectional view of FIG. 29A except for the airbags 4c and 4d in the center row of the upper base 1 which are inflated by the adjustment in the supine posture. Withered as shown. In the arrangement diagram of FIG. 29 (B), the airbags 4c and 4d in the center row of the upper base 1 are hatched to indicate that they are inflated, and all other airbags have zero air. The outline display indicates that there is.
FIG. 30 is a diagram illustrating a state of the airbag after the adjustment in the height setting of the rightward lying sideways posture.

The user 400 operates the remote controller 35 in the right-side lying posture to inject air into the airbags 4a and 4b provided in the right column of the upper base 1. Then, the user 400 adjusts the air amount so that each of the airbags 4a and 4b reaches an appropriate height (a desired height) as shown in the cross-sectional view of FIG. As a result of such adjustment, the airbags 4a, 4b, 4c, and 4d provided in the center row and the right row of the upper base 1 are inflated, as indicated by hatching in the layout diagram of FIG. State.
FIG. 31 is a diagram illustrating a height to be adjusted by setting the height of the left-facing lying posture.

In the case of the left-facing lying posture, similarly to the case of the right-facing lying posture, the height of the pillow 100 is, for example, the height difference T5 between the lowermost point of the shoulder and the temporal region, and the lowermost point of the shoulder. It is said that the height that compensates for the height difference T6 from the side of the neck is appropriate. In the actual adjustment, the height difference T5, T6, the amount by which the pillow 100 sinks into the bed or the futon, and the preference of the user 400 are reflected.
FIG. 32 is a diagram illustrating a state of the airbag before adjustment in the height setting of the left sideways lying posture.

Before the adjustment in the left sideways posture, other airbags except for the four airbags 4a, 4b, 4c, and 4d of the upper base 1 which are inflated by the adjustment in the back posture and the right sideways posture are shown in FIG. As shown in the cross-sectional view of FIG. In the arrangement diagram of FIG. 32B, the four airbags 4a, 4b, 4c, and 4d of the upper base 1 are hatched to indicate that they are inflated, and all other airbags are inflated. The white display indicates that the air is zero.
FIG. 33 is a diagram illustrating a state of the airbag after the adjustment with the height setting of the left-facing lying posture.

  The user 400 operates the remote controller 35 in the left sideways lying posture to inject air into the airbags 4e and 4f provided in the left row of the upper base 1. Then, the user 400 adjusts the amount of air so that each of the airbags 44e and 4f reaches an appropriate height (a desired height) as shown in the sectional view of FIG. As a result of such adjustment, all the airbags 4a,..., 4f of the upper base 1 are in an inflated state as shown by oblique lines in the arrangement diagram of FIG.

By the above height adjustment, the height of the pillow 100 becomes an appropriate height for any sleeping posture of the user 400, and can contribute to comfortable sleep. Since the airbags 4a,..., 4f are provided in the three rows of the center left and right, the center left and right of the pillow 100 can be individually deformed, and a useful deformation for the user can be easily realized.
The height set as described above in the height setting can be reproduced by the function of the control box 200 described above.
Next, the operation of the pillow 100 when turning over will be described. This operation is performed in the above-described auto mode.

  FIG. 34 is a diagram illustrating a state before turning over. FIG. 34 (A) shows a schematic cross-sectional view as viewed from the top of the user's head, and FIG. 34 (B) shows a reaction state of the pressure sensor 17 and the voice sensor 18.

Before turning over, the heights of the airbags 4a, 4c, 4e are adjusted to the heights set above. Further, as indicated by hatching in FIG. 34B, pressure is applied to both of the two pressure sensors 17, and the pressure is detected by both of the pressure sensors 17. It is assumed that the voice sensor 18 has not detected voice. By detecting the pressure by the pressure sensor 17 in this way, it is recognized that the user 400 has his / her head on the pillow 100, and the above-described auto mode is activated.
FIG. 35 is a diagram illustrating a state in which the user 400 turns to the left.

When the user 400 turns to the left, the position of the user 400's head moves toward the left airbag 4e, as shown in FIG. As a result, as shown in FIG. 35B, the left pressure sensor 17 of the two pressure sensors 17 detects a high pressure. By this detection, the pillow system 1000 recognizes the turning of the user 400 to the left.
FIG. 36 is a diagram illustrating an operation of the pillow 100 corresponding to the turning of the user 400 to the left.

  When the pillow system 1000 recognizes that the user 400 has turned to the left, air is injected into the central row of airbags 5b and 5c among the three rows of airbags 5a,..., 5d provided on the lower base 2. You.

  When air is injected into the airbag 5b of the lower base 2 as shown in FIG. 36 (A), the upper base 1 bends so that the center row is lifted. The swelling of the airbag 5b of the lower base 2 deflects the upper base 1 due to the flexibility of the above-described sheet base 3 and base base 6 in the upper base 1, and the pillow 100 is appropriately deformed by the swelling of the airbag 5b. Occurs. The above-described bent structure of the upper base 1 and the lower base 2 also contributes to efficient deformation of the pillow 100.

Due to the deformation of the pillow 100 due to the inflation of the airbag 5b, the height of the airbag 4c in the center row of the upper base 1 (that is, the height of the center of the pillow 100) is changed to the left row (that is, the row on which the user has turned over) The height is equal to the height of the airbag 4e (that is, the height on the left side of the pillow 100). In other words, the air having such a uniform height is injected into the airbag 5b of the lower base 2. The amount of air injected at this time is desirably an air amount according to the height of the airbag 4e adjusted by the user 400 at the above-described height setting. By aligning the center of the pillow 100 and the height of the left side in this manner, the sleeping comfort in the left sideways lying posture is improved, and the sleep is maintained.
FIG. 37 is a diagram illustrating a state where the user 400 turns rightward.

When the user 400 turns rightward, as shown in FIG. 37A, the position of the user 400's head moves toward the right airbag 4a. As a result, as shown in FIG. 37B, the right pressure sensor 17 of the two pressure sensors 17 detects a high pressure. This detection allows the pillow system 1000 to recognize that the user 400 has turned rightward.
FIG. 38 is a diagram illustrating the operation of the pillow 100 in response to the user 400 turning to the right.

  When the pillow system 1000 recognizes that the user 400 has turned rightward, air is injected into the central row of airbags 5b and 5c among the three rows of airbags 5a,..., 5d provided on the lower base 2. You.

When air is injected into the airbag 5b of the lower base 2 as shown in FIG. 38 (A), the upper base 1 bends so that the center row is lifted. As a result, the height of the airbag 4c in the center row of the upper base 1 (that is, the height of the center of the pillow 100) is the height of the airbag 4a in the right row (that is, the row on which the user has turned over) (that is, the pillow). 100 right). In other words, the air having such a uniform height is injected into the airbag 5b of the lower base 2. The amount of air injected at this time is desirably an air amount according to the height of the airbag 4a adjusted by the user 400 at the above-described height setting. As described above, the center and the right height of the pillow 100 are aligned, so that the sleeping comfort in the lying posture in which the pillow 100 is turned is improved.
Next, the operation of the pillow 100 during snoring will be described. This operation is also performed in the above-described auto mode.
FIG. 39 is a diagram showing a snoring detection state.

When the user 400 is not snoring, the sound sensor 18 does not detect sound, but when the user 400 snores, the sound sensor 18 detects sound. Since the voice sensor 18 is provided left and right apart, the sound of snoring is detected even when the user 400 is sleeping at any position.
The sound detected by the sound sensor 18 is analyzed by the control board 30 of the control box 200 for frequency components and the like, and it is confirmed that the sound is a snoring sound.

  FIGS. 40 and 41 are diagrams illustrating a first operation when snoring is detected. FIG. 40 shows the operation of the airbag in the first operation, and FIG. 41 shows the movement of the head by the first operation.

In the first operation, as shown in the layout diagram of FIG. 40B, of the three rows of airbags 4a,... , Air discharge and injection are repeated. As a result, as shown in the cross-sectional view of FIG. 40A, the height of the pillow 100 goes up and down at the place where the head of the user 400 is placed. As the height of the pillow 100 goes up and down (particularly, the back of the neck of the user 400 goes up and down), the head and neck of the user 400 are moved up and down as shown in FIG. Is stimulated. Such stimulation is expected to contribute to the suppression of snoring.
When the voice sensor 18 stops detecting the snoring sound, the first operation is finished, and the air amount of each airbag returns to the air amount at the time of setting the height.

  FIGS. 42 and 43 are diagrams illustrating a second operation when snoring is detected. FIG. 42 shows the operation of the airbag in the second operation, and FIG. 43 shows the movement of the head by the second operation.

  In the present embodiment, the second operation is an operation executed in place of the above-described first operation. For example, it is determined which of the first operation and the second operation is to be executed by selection setting by the user 400 or the like.

In the second operation, as shown in the layout diagram of FIG. 42B, of the three rows of airbags 5a,. , Air discharge and injection are repeated. As a result, as shown in FIG. 43, the upper base 1 bends so that the center moves up and down as the airbags 5b and 5c of the lower base 2 expand and contract. Therefore, as shown in the cross-sectional view of FIG. 42 (A), the height of the pillow 100 goes up and down at the place where the head of the user 400 is placed.
The above-described bending structure of the upper base 1 and the lower base 2 contributes to the efficient deformation of the pillow 100 even in the second operation.

The up and down movement in the second operation is an up and down movement in a direction higher than the height adjusted by the above-described height setting, and as shown in FIG. Is also moved up and down at a high position. This vertical movement gives the user 400 a stronger stimulus than the first operation. Such stimuli are also expected to contribute to the suppression of snoring.
The second operation also ends when the voice sensor 18 stops detecting the snoring sound, and the air amount of each airbag returns to the air amount at the time of setting the height.

FIG. 44 and FIG. 45 are diagrams illustrating a third operation when snoring is detected. FIG. 44 shows the operation of the airbag in the third operation, and FIG. 45 shows the movement of the head by the third operation.
In the present embodiment, the third operation is also an operation executed in place of the above-described first operation and second operation.

In the third operation, of the three rows of airbags 5a,..., 5d provided on the lower base 2, air is injected into the left row of airbags 5d. As a result, the left side of the upper base 1 bends, and the height of the left side of the pillow 100 becomes higher than the height adjusted by the height setting. As a result, it is difficult for the user 400 to turn his head to the left. Then, as shown in FIG. 45, the user 400 is encouraged to turn to the right so as to escape from the pressure from the left. Such turning over is expected to contribute to the suppression of snoring. The above-described bent structure of the upper base 1 and the lower base 2 contributes to the efficient deformation of the pillow 100 even in the third operation.
The third operation also ends when the voice sensor 18 stops detecting the snoring sound, and the air amount of each airbag returns to the air amount at the time of setting the height.

FIG. 46 and FIG. 47 are diagrams illustrating a fourth operation when snoring is detected. FIG. 46 shows the operation of the airbag in the fourth operation, and FIG. 46 shows the movement of the head by the fourth operation.
In the present embodiment, the fourth operation is also an operation executed in place of the above-described first operation, second operation, and third operation.

In the fourth operation, of the three rows of airbags 5a,..., 5d provided on the lower base 2, air is injected into the right row of airbags 5a. As a result, the right side of the upper base 1 bends, and the height of the right side of the pillow 100 becomes higher than the height adjusted by the height setting. As a result, it is difficult for the user 400 to turn his head to the right. Then, as shown in FIG. 47, the user 400 is encouraged to turn to the left so as to escape from the pressure from the right. Such turning over is expected to contribute to the suppression of snoring. The above-described bending structure of the upper base 1 and the lower base 2 contributes to efficient deformation of the pillow 100 even in the fourth operation.
The fourth operation also ends when the voice sensor 18 stops detecting the snoring sound, and the air amount of each airbag returns to the air amount at the time of setting the height.

Any of the above-described first to fourth operations may be selected and only the selected operation may be executed. For example, the operations may be sequentially switched until the effect of suppressing snoring is obtained. May be done.
Hereinafter, modified examples and other embodiments of the first embodiment will be described.
FIG. 48 and FIG. 49 are views showing a modified example in which the location of the sensor is different. 48 shows a perspective view, and FIG. 49 shows a side view.

In the above-described first embodiment, the pressure sensor 17 and the sound sensor 18 are fixed on the surface of the base member 6, whereas in this modified example, the base member includes the upper base member 6 a and the lower base member 6. The pressure sensor 17 and the sound sensor 18 are embedded in the hole H of the upper base member 6a. By embedding the sensor in the base material as described above, the integrity of the entire pillow is improved, and the displacement of the sensor is prevented.
FIGS. 50 to 52 are diagrams showing modified examples having different sensor shapes. 50 shows a top view, FIG. 51 shows a perspective view, and FIG. 52 shows a side view.

  In this modification, one long pressure sensor 17 is used. The pressure sensor 17 cannot detect the position of the head of the user 400, but can reliably detect the pressure regardless of the position of the head of the user 400 on the pillow 100.

  In addition, the location of the pressure sensor 17 and the voice sensor 18 in this modified example is between the sheet base 3 and the base base 6 as in the first embodiment described above. It is fixed on the surface of the base substrate 6.

  FIG. 53 to FIG. 55 are views showing modified examples in which the location of the sensor is further different. FIG. 53 shows the back surface of the sheet substrate 3, FIG. 54 shows a perspective view, and FIG. 55 shows a side view.

  Also in this modified example, the pressure sensor 17 and the sound sensor 18 are provided between the sheet base 3 and the base 6, but the pressure sensor 17 and the sound sensor 18 are fixed on the back surface of the sheet base 3. is there.

As described above, various modes can be adopted as a fixing portion and a fixing method of the pressure sensor 17 and the sound sensor 18, but the detection performance of the sensor decreases as the distance from the sheet base 3 of the upper base 1 decreases. Therefore, it is preferable that the installation location is between the sheet base 3 and the base 6 of the upper base 1.
FIG. 56 is a diagram showing a modification in which the configuration of the repulsion sheet is different.

In the modification shown in FIG. 56, the repulsion sheet is formed by superposing a plurality of (two in this example) sheets of a first sheet 8a and a second sheet 8b. Then, a combination of the hardness of the plurality of sheets 8a and 8b is selected according to the user's preference. Since the hardness of the rebound sheet depends on the material, it is better to combine the hardness of the plurality of sheets 8a and 8b than to prepare the repulsion sheets of many materials having different hardnesses. And the degree of freedom of selection by the user increases.
FIG. 57 is a diagram showing a modification in which the configuration of the repulsion sheet is further different.

  In the modification shown in FIG. 57, the repulsion sheet is divided into a plurality of (two in this example) regions in the in-plane direction in which the sheet spreads. That is, the rear second seat 8b1 and the front second seat 8b2 are used instead of the second seat 8b shown in FIG. When the user 400 selects the hardness of the pillow 100, a different hardness may be desired depending on the position of the pillow 100 (particularly, the front-back position), and the modification shown in FIG. 57 corresponds to such a preference. be able to.

  FIG. 58 is a schematic sectional view showing a second embodiment of the pillow of the present invention, FIG. 59 is a perspective view schematically showing a housing structure in a cover, and FIG. It is a side view which shows typically.

  In the pillow 101 of the second embodiment, the upper base 1 and the lower base 2 are accommodated in the interior covered by the outer cover 10 and the inner cover 9 so as to overlap with each other. Unlike the first embodiment, the upper base 1 does not cover the lower base 2 but simply overlaps the lower base 2.

Similarly to the first embodiment, the upper base 1 and the lower base 2 in the second embodiment also have a base substrate 6 attached to the back surface side of the sheet substrate 3. Thereby, the warpage of the sheet substrate 3 is suppressed by the base substrate 6 as described with reference to FIG. In the case of the second embodiment, a material having the same flexibility as the combined flexibility of the sheet base 3 and the base 6 may be used as the sheet base 3. By using such a material as the sheet base material 3, a simple structure without the base material 6 is realized.
FIG. 61 is a top view showing the structure of the upper base 1 in the second embodiment, and FIG. 62 is a top view showing the structure of the lower base 2 in the second embodiment.

In the second embodiment, the outer peripheral shapes of the upper base 1 and the lower base 2 are similar. Also, on the surface of the upper base 1, six airbags 4a,..., 4f are provided in three rows, for example, left, middle, and right, and on the surface of the lower base 2, four airbags 5a, 5a, ,..., 5d are provided in three rows on the left, middle, and right sides.
In the second embodiment as well, the same operation as the first embodiment is realized, and a large deformation for improving the sleeping posture of the user can be obtained.
FIG. 63 to FIG. 67 are views showing a third embodiment of the pillow of the present invention.

  The pillow 102 of the third embodiment is provided with an upper base 1 in which a lower base 2 is wrapped, as in the first embodiment. In the pillow 102 of the third embodiment, the sleeping comfort around the neck of the user 400 is improved. Specifically, a neck part 13 located around the neck of the user 400 is provided at a part of the front of the upper base 1, and the upper base 1 is recessed inside the upper base 1. It has a structure. Since the neck circumference 13 is thus recessed, the comfort of the pillow 102 against the neck of the user 400 and the fit of the neck are improved, and the sleeping comfort of the user 400 is improved.

  As shown in the developed view of FIG. 66, the neck circumference 13 forms a protruding piece, and the concave snaps 28_a7, 28_a8 provided on the neck circumference 13 are connected to the left and right protruding pieces 3a, By being fixed to the convex snaps 28_b7, 28_b8 provided on the 3b, a structure concaved around the neck can be easily obtained.

Also, as shown in FIG. 67, among the four airbags 5a,..., 5d provided on the lower base 2, the airbag 5c located at the neck of the user 400 Correspondingly, the lower base 2 has a concave shape toward the center.
68 to 69 are views showing a pillow according to a fourth embodiment of the present invention.

In the pillow 103 of the fourth embodiment (illustrations such as a cover and a repulsion sheet are omitted), the base material 3 of the upper base 1 A hole 3e for enhancing flexibility is provided. As a result of increasing the flexibility of the side surface of the base member 3 by such holes 3e, the pillow 103 is easily crushed by the weight W of the head of the user 400 placed on the pillow 103 as shown in FIG. For this reason, the height of the pillow 103 when the airbags 4a,..., 4f are deflated is sufficiently reduced. It becomes possible.
FIG. 70 is a development view of the upper base 1 in the fourth embodiment.
The holes 3e described above are provided in the front, rear, left and right protruding pieces 3a, 3b, 3c, 3d.
Also in the fourth embodiment, the shape in which the upper base 1 wraps the lower base 2 can be easily assembled by snap fastening in a snap arrangement as shown in the drawing.
FIG. 71 is a diagram illustrating a bending structure according to the fourth embodiment.

Also in the pillow 103 of the fourth embodiment, the bent structure described in the first embodiment is effective. By adopting the bent structure that bends inward as indicated by the arrow in the figure, the distance between the airbags is reduced even in the pillow 103 of the fourth embodiment, and the sleeping comfort is improved. Further, such a bent structure contributes to efficient deformation of the pillow 103 when the airbag of the lower base 2 is inflated.
FIG. 72 and FIG. 73 are views showing a fifth embodiment of the pillow of the present invention.

  In the pillow 104 of the fifth embodiment, similarly to the pillow 103 of the fourth embodiment, the base material 3 of the upper base 1 has the flexibility of the base material 3 Is provided. Therefore, the pillow 104 is easily crushed by the weight W of the head of the user 400, and the adjustable range in the height setting is wide.

Moreover, in the pillow 104 of the fifth embodiment, similarly to the pillow 102 of the third embodiment, a neck part 13 located around the neck of the user 400 is provided in a part of the front of the upper base 1. Therefore, the comfort of the pillow 102 against the neck of the user 400 and the fit of the neck are improved.
FIG. 74 is a development view of the upper base 1 in the fifth embodiment.
