Hereinafter, embodiments of the pillow and sleep state control system according to the present disclosure will be described with reference to the drawings. It should be noted that the present invention is not limited to the following examples, but is shown in the claims and is intended to include all modifications within the scope equivalent to the claims. In the description of the drawings, the same or corresponding elements are designated by the same reference numerals, and duplicate description will be omitted as appropriate. In addition, the drawings may be partially simplified or exaggerated for easy understanding, and the dimensional ratio and the like are not limited to those described in the drawings.

FIG. 1 is a perspective view showing a pillow 1 according to an embodiment. FIG. 2 is a plan view schematically showing the inside of the pillow 1 of FIG. As shown in FIGS. 1 and 2, the pillow 1 includes a side land 2, a content 3 housed inside the side land 2, a light emitting portion 4 provided inside the side land 2, and a side land. A vibrating portion 5 provided inside the 2 and a heat generating portion 6 provided inside the side ground 2 are provided.

For example, the material of the side 2 includes at least one of cotton and polyester. However, the material of the side land 2 can be changed as appropriate. The color of the side area 2 is cool (black as an example). In this case, the light from the light emitting unit 4 built in the side ground 2 can be appropriately emitted to the extent that the light is not dazzled too much. However, the color of the side area 2 does not have to be a cool color and can be changed as appropriate. Further, the side ground 2 may include one white cloth and one black cloth. In this case, since the light from the light emitting portion 4 can be diffused by the white cloth of the side ground 2, warm and soft light can be emitted from the light emitting portion 4 through the side ground 2.

For example, the side land 2 is provided with a gusset 2a that is oriented in the horizontal direction. The content 3 is, for example, cotton, but the type of the content 3 can be changed as appropriate. For example, the content 3 may be a crushed puff. As an example, this puff is made of rubber and is also used for cosmetic purposes. Further, a fastener may be provided on the side ground 2, and the amount of the contents 3 inside the side ground 2 may be adjustable by opening and closing the fastener.

In the present specification, the "pillow" refers to the one on which the body of the user M is placed. A "pillow" includes a cushion, along with, for example, a dakimakura, a sleeping pillow, a nap pillow, and a portable pillow. The "cushion" may be, for example, a ring-shaped nap cushion. The "contents" are those housed inside the side of the pillow, for example, a flexible material containing cotton (wat) including polyester grain cotton, urethane and feathers. Further, the "content" may contain at least one of a hollow granular material and a solid granular material. The hollow granules include, for example, hollow pipe materials or beads, and the solid granules include buckwheat husks, cypress, adzuki beans, and the like.

Further, the pillow 1 includes a wake-up means 10 including a light emitting unit 4, a vibrating unit 5, and a heat generating unit 6, and a sleeping means 20 including a light emitting unit 4 and a heat generating unit 6. The wake-up time can be set in the wake-up means 10. The wake-up means 10 (light emitting unit 4, vibrating unit 5, and heat generating unit 6) operates at the set wake-up time to awaken and wake up the user M. The sleep-onset means 20 (light emitting unit 4 and heat-generating unit 6) operates, for example, after the wake-up time is set in the wake-up means 10, to put the user M to sleep.

As used herein, the term "wake-up means" refers to means for encouraging the pillow user to wake up. The "wake-up means" includes, for example, an audio output unit for waking up the user at the time of waking up, a vibrating unit for waking up the user (for example, a vibrator), a light emitting part for waking up the user (for example, a light), and the user. It may be a heat generating part (for example, a heater) for waking up, or a scent generating part for waking up the user. "Wake-up time" indicates the wake-up time set by the user.

The "wake-up time" includes both the wake-up time set by the user and the time from the time before the wake-up time to the wake-up time. As a specific example, when the wake-up time is set at 6 o'clock, the "wake-up time" includes 30 minutes from the time before the predetermined time (for example, 5:30 30 minutes before) to 6 o'clock. Further, the "wake-up time" may be set as the wake-up time, or may be set as a time having a predetermined range (for example, between 5:30 and 6:00).

"Means for falling asleep" indicates means for encouraging the user of the pillow to fall asleep. The "sleeping means" includes, for example, a voice output unit for promoting sleep (for example, a speaker for outputting sleepy music), a vibration output unit for promoting sleep, a light emitting unit for promoting sleep, and a heat generating unit for promoting sleep. Alternatively, it may be a scent generating part for promoting falling asleep.

The pillow 1 according to the present embodiment is a body pillow that extends long in one direction D1. As an example, the pillow 1 has a lightning shape as a whole, and is a body pillow with relatively few curved portions. The pillow 1 includes, for example, a concave arm portion 1a facing the arm of the user M and a linear abdomen 1b facing the abdomen of the user M, and the abdomen 1b is an arm portion in the width direction D2 of the pillow 1. It is provided on the opposite side of 1a.

The pillow 1 further includes an upper body side portion 1c located on one side of the arm portion 1a in one direction D1 and a lower body side portion 1d located on the other side of the arm portion 1a in one direction D1. The upper body side portion 1c extends obliquely from both the first upper body portion 1e extending from the abdomen 1b and the end opposite to the abdomen 1b of the first upper body portion 1e in both the unidirectional D1 and the width directions D2. It has an inclined portion 1f and a second upper body portion 1g that forms an acute angle with the inclined portion 1f and extends from the inclined portion 1f to the arm portion 1a. For example, a recess 1h is formed in the first upper body portion 1e, and the recess 1h is slightly recessed from each of the first upper body portion 1e and the abdomen 1b.

The lower body side portion 1d forms an acute angle with the inclined portion 1k, the protruding portion 1j protruding from the arm portion 1a, the inclined portion 1k extending from the protruding portion 1j to the opposite side of the arm portion 1a, and the inclined portion 1k to the abdomen 1b. It has an extending portion of 1 m extending to. For example, the arm portion 1a, the protruding portion 1j, and the inclined portion 1k project so as to form an obtuse angle.

The light emitting unit 4, the vibrating unit 5, and the heat generating unit 6 are built in, for example, inside the side ground 2. The light emitting unit 4, the vibrating unit 5, and the heat generating unit 6 operate by receiving electric power from, for example, a battery. As an example, the battery is a rechargeable lithium-ion battery. In this way, since the light emitting unit 4, the vibrating unit 5, and the heat generating unit 6 operate by receiving electric power from the battery, it is possible to eliminate the need for wiring extending from the pillow 1. The pillow 1 is further provided with, for example, a switch 7, and it is possible to stop the operation of at least one of the light emitting unit 4, the vibrating unit 5, and the heat generating unit 6 by operating the switch 7. The switch 7 may be a switch for turning the power on or off, and a part of the operation of the light emitting unit 4, the vibrating unit 5, and the heat generating unit 6 may be performed by a mobile terminal outside the pillow 1 (for example, information described later). It may be performed at the terminal 70).

The light emitting portion 4 is provided on, for example, the upper body side portion 1c of the pillow 1, and is arranged along the inclined portion 1f located at the end of one direction D1 of the pillow 1 as an example. In this case, since the light emitting unit 4 is provided at a position close to the face of the user M, the effects of falling asleep and waking up due to light emission can be enhanced.

The vibrating unit 5 is built in, for example, a region including the center of the pillow 1. The heat generating portion 6 is arranged along the abdomen 1b of the pillow 1, for example. In this case, since the heat generating portion 6 is provided at a position facing the abdomen of the user M, the abdomen of the user M can be effectively warmed when falling asleep and waking up. However, the arrangement of the light emitting portion 4, the vibrating portion 5, and the heat generating portion 6 inside the side ground 2 can be changed as appropriate.

FIG. 3 is a plan view showing a detailed example of the light emitting unit 4. As shown in FIGS. 2 and 3, the light emitting unit 4 also serves as, for example, both the wake-up means 10 and the sleep-onset means 20. The light emitting unit 4 includes, for example, a light emitting unit 4a when falling asleep and a light emitting unit 4b when waking up. For example, when the light emitting unit 4 functions as the wake-up means 10, the light emitting unit 4b at the time of waking up emits light, and when the light emitting unit 4 functions as the sleeping means 20, the light emitting unit 4a at the time of falling asleep emits light.

For example, the light emitting unit 4a when falling asleep and the light emitting unit 4b when waking up both include a plurality of LEDs 4c, and the plurality of LEDs 4c are arranged in a grid pattern, for example. Each LED 4c of the light emitting unit 4a at the time of falling asleep and each LED 4c of the light emitting unit 4b at the time of waking up are arranged along a certain direction. For example, each LED 4c of the light emitting unit 4a when falling asleep is a warm color LED, and each LED 4c of the light emitting unit 4b when waking up is a cold color LED.

For example, the color of the light of the light emitting unit 4 as the sleep falling means 20 and the color of the light of the light emitting unit 4 as the wake-up means 10 are different from each other. As an example, the light emitting unit 4 as the sleep onset means 20 emits light at the time of falling asleep, and the light emitting unit 4 as the wake up means 10 emits light at the time of waking up. For example, the color of the light of the light emitting unit 4 when falling asleep is a warm color system, and the color of the light of the light emitting unit 4 when waking up is a cool color system.

For example, the color of the light of the light emitting unit 4a when falling asleep may be a warm color (orange as an example), and the color of the light of the light emitting unit 4b when waking up may be a daylight color (as an example, pale light). In this case, the user M can be effectively invited to sleep when falling asleep, and can wake up cleanly when waking up.

The light emitting unit 4 (light emitting unit 4a at the time of falling asleep) as the sleep falling means 20 may change the brightness of the emitted light according to the passage of time. In this case, since the light emitting unit 4 can express the fluctuation of light like a fire when falling asleep, it is possible to enhance the relaxing effect at the time of falling asleep and invite the user M to sleep more effectively and comfortably. The light emitting unit 4a at the time of falling asleep may gradually reduce the brightness of the emitted light with the passage of time. Further, the light emitting unit 4 (light emitting unit 4a at the time of falling asleep) as the sleep falling means 20 may stop emitting light after a certain period of time has elapsed. In this case, power consumption can be reduced.

The light emitting unit 4 (light emitting unit 4b at the time of waking up) as the wake-up means 10 starts emitting light within the wake-up time set in the wake-up means 10, for example. The light emitting unit 4 as the wake-up means 10 may gradually increase the brightness of the emitted light with the passage of time. As described above, the mode of light emission of the light emitting unit 4 as the wake-up means 10 and the mode of light emission of the light emitting unit 4 as the sleep-onset means 20 can be appropriately changed.

In addition, the number, type, and arrangement of the light emitting unit 4a when falling asleep and the light emitting unit 4b when waking up can be appropriately changed. The colors of the light emitting unit 4a when falling asleep and the light emitting unit 4b when waking up are not limited to the above-mentioned warm colors and cold colors, and can be changed as appropriate. Further, the light emitting unit 4 may be composed of a full-color LED.

The vibrating unit 5 includes, for example, a motor 5a that operates by receiving electric power. The vibrating unit 5 functions as, for example, the wake-up means 10. For example, the vibrating unit 5 may start vibration within the wake-up time set in the wake-up means 10, and the strength of the vibration may be gradually increased with the passage of time. In this case, the user M can be gradually led to awakening and waking up.

The vibrating unit 5 may, for example, transmit vibration to the upper body (which may be the abdomen) of the user M to urge the user M to wake up. The vibrating unit 5 may include, for example, two motors 5a. Further, the vibration intensity of the vibrating unit 5 may be switched to a plurality of stages (for example, two stages of "strong" and "weak") by the switch 7. Further, the strength of vibration of the vibrating unit 5 may be switched by an external mobile terminal (for example, an information terminal 70 described later).

The vibrating unit 5 does not function as, for example, the sleeping means 20 and does not vibrate when falling asleep. However, the vibrating unit 5 may function as a sleep-onset means 20, for example, a very weak vibration and a vibration having a comfortable frequency may be applied at the time of falling asleep to invite the user M to fall asleep. As described above, the vibration mode (vibration magnitude, timing, etc.) of the vibrating unit 5 can be appropriately changed.

The heat generating unit 6 is a heater that operates by receiving electric power, and includes, for example, one heat sensitive wire. The heat generating unit 6 functions as, for example, the wake-up means 10 and the sleep-onset means 20. That is, the heat generating unit 6 generates heat when it functions as the wake-up means 10 and when it functions as the sleep-onset means 20. For example, the amount of heat generated by the heat-generating unit 6 when functioning as the sleep-onset means 20 (the amount of heat generated by the heat-generating unit 6 when falling asleep) and the amount of heat generated by the heat-generating unit 6 when functioning as the wake-up means 10 (heat-generating unit 6 when waking up) The calorific value of) is different from each other.

For example, the amount of heat generated by the heat generating unit 6 when falling asleep (the amount of heat generated by the heat generating unit 6) is lower than the amount of heat generated by the heat generating unit 6 when waking up. As a result, it is possible to prevent the temperature of the heat generating portion 6 from becoming too hot when falling asleep, and it is possible to surely wake up the user M when waking up. The heat generating unit 6 may change the amount of heat generated with the passage of time. Further, the heat generating unit 6 may stop heat generation after a certain period of time has elapsed. In this case, power consumption can be reduced. The heat generating unit 6 starts heat generation within the wake-up time set in the wake-up means 10, for example. At this time, the heat generating unit 6 may gradually increase the amount of heat generated with the passage of time.

For example, the heat generating portion 6 may warm the abdomen or inner thigh of the user M when falling asleep and when waking up. The set temperature of the heat generating unit 6 may be switched to a plurality of stages (for example, three stages of "23 ° C.", "33 ° C." and "43 ° C.") by the switch 7. Further, the set temperature of the heat generating unit 6 may be switched by an external mobile terminal (for example, an information terminal 70 described later). Further, when it is hot, for example, in summer, the heat generation of the heat generating portion 6 may be stopped by the switch 7. Further, the pillow 1 may be provided inside the side area 2 and may be provided with a cooling unit for cooling the body for a hot season such as summer.

Next, the action and effect obtained from the pillow 1 according to the present embodiment will be described in detail. In the pillow 1, the content 3 is housed inside the side land 2, and a wake-up means 10 for waking up the user M is provided inside the side land 2. Further, in the pillow 1, the wake-up time can be set in the wake-up means 10, and the wake-up means 10 operates when the set wake-up time is reached to wake up the user M. Since the wake-up means 10 is built in the side ground 2, it is possible to prevent the presence of a cord or the like extending from the pillow 1 to the outside. Therefore, since it is possible to prevent the portion extending outward from the pillow 1 from coming into contact with the body of the user M, it can be used in the same manner as a normal pillow, and the usability can be improved.

In the present embodiment, the wake-up means 10 includes a light emitting unit 4 that emits light during a set wake-up time and a vibrating unit 5 that vibrates during the wake-up time. Therefore, the light emitting unit 4 emits light at the set wake-up time, so that the user M of the pillow 1 can be visually urged to wake up. Further, since the vibrating unit 5 vibrates at the set wake-up time, the vibration of the pillow 1 can urge the user M to wake up.

In the present embodiment, the wake-up means 10 includes a heat-generating portion 6 that generates heat during a set wake-up time. Therefore, the heat generating portion 6 generates heat at the set wake-up time, so that the user M can be urged to wake up by heating.

In the present embodiment, the pillow 1 is provided inside the side ground 2, and further includes a sleep-onset means 20 that operates after the wake-up time is set. Therefore, the sleep onset means 20 is activated after the wake-up time is set. Therefore, the sleep-onset means 20 can promote the sleep of the user M after setting the wake-up time, and can improve the sleep of the user M, so that a comfortable sleep can be provided to the user M.

In the present embodiment, the sleep-onset means 20 includes a light emitting unit 4 that emits light after the wake-up time is set, and a heat-generating unit 6 that generates heat after the wake-up time is set. Therefore, the light emitting unit 4 emits soft light when falling asleep, so that the user M can be invited to a comfortable sleep. Further, since the heat generating portion 6 generates heat when falling asleep, the body of the user M can be warmed when falling asleep, and the relaxing effect can be enhanced, so that the falling asleep can be further improved.

In the present embodiment, the pillow 1 is a body pillow that extends long in one direction D1. Therefore, not only the head of the user but also the arms and abdomen of the user M can be applied to rest the body, which contributes to further improvement of the relaxing effect. Further, since the wake-up means 10 is provided on the body pillow, the operation of the wake-up means 10 can be directly transmitted to the arms and abdomen of the user M's body, so that the user M can be more reliably woken up. it can.

Further, in the pillow 1 according to the present embodiment, the content 3 is housed inside the side ground 2, and a light emitting portion 4 and a vibrating portion 5 are provided inside the side ground 2. Therefore, the user M can be woken up at the wake-up time by the light emitted from the light emitting unit 4 and the vibration from the vibrating unit 5. Since the light emitting unit 4 and the vibrating unit 5 are provided inside the side ground 2, it is possible to prevent the presence of a cord or the like extending to the outside of the pillow 1. Therefore, since it is possible to prevent the portion extending outward from the pillow 1 from coming into contact with the body of the user M, it can be used in the same manner as a normal pillow, and the usability can be improved.

As shown in FIGS. 4 and 5, the pillow 1 can be interlocked with the bedding 8 via, for example, the sleep state control system 50. As used herein, the term "bedding" refers to a bedding that the user's body is applied to when the user rests or sleeps, and is typically a mattress or mattress.

For example, the bedding 8 is a mattress that measures the sleeping state of the user M when the user M sleeps. "Measuring the sleep state" means, for example, determining the sleep depth (sleep depth) of the user by measuring at least one of the user's respiration, heartbeat, body movement, and blood pressure during sleep. And show that you get information about your sleep status.

The bedding 8 has a sensor 9 that acquires the sleeping state of the user M with the body of the user M placed on the bedding 8. The sensor 9 may include, for example, a respiratory heart rate measuring sensor that measures the breathing and heartbeat of the user M, or may include a body motion measuring sensor that acquires the body movement of the user M during sleep. Good. However, the type of sensor included in the sensor 9 of the bedding 8 can be changed as appropriate.

As an example, the respiratory heart rate measuring sensor is a piezoelectric sensor including a coaxial line, and the body motion measuring sensor is a strain sensor having elasticity. Further, the body motion measurement sensor may be a rubber-like capacitance sensor. In this case, the body motion measurement sensor includes a plurality of metal pieces and a dielectric located between the plurality of metal pieces, and the distance between the plurality of metal pieces changes with an external force to increase the capacitance. The body movement of the user M may be measured by changing.

The sleep state control system 50 includes the pillow 1 and bedding 8 described above, a control unit 60, and an information terminal 70. The information terminal 70 includes a mobile terminal such as a smartphone or a tablet, and a computer such as a personal computer or a laptop computer. The control unit 60 is provided in a computer, for example, and is capable of communicating with each of the communication unit 1n of the pillow 1, the communication unit 8a of the bedding 8, and the information terminal 70.

The communication unit 1n of the pillow 1 is, for example, a network module built in the side area 2 and includes a wireless LAN or a wireless communication interface such as Bluetooth (registered trademark). Each of the light emitting unit 4, the vibrating unit 5, and the heat generating unit 6 of the pillow 1 described above can receive wireless data from the control unit 60 via the communication unit 1n.

The communication unit 8a of the bedding 8 is, for example, a network module built in the side area 8c, and may have the same configuration as the communication unit 1n, for example. In addition, at least a part of the functions of the control unit 60 may be built in either the pillow 1 or the bedding 8, and in this case, the communication unit 1n or the communication unit 8a can be eliminated.

The computer provided with the control unit 60 is, for example, an auxiliary composed of a processor (for example, a CPU) for executing an operating system, an application program, or the like, a main storage unit composed of a ROM, a RAM, or the like, and a hard disk, a flash memory, or the like. It includes a storage unit and a communication control unit composed of a network card or a wireless communication module.

Each component of the computer of the control unit 60 is realized by having a processor or a main storage unit read a predetermined software and executing the software. The processor operates the communication control unit according to the software, and reads and writes data in the main storage unit or the auxiliary storage unit. The data required for computer processing is stored in the main storage unit or the auxiliary storage unit.

The control unit 60 receives, for example, the sleep state acquired by the bedding 8 from the communication unit 8a of the bedding 8. As an example, the control unit 60 analyzes the breathing and heartbeat of the user M measured by the respiratory heart rate measuring sensor of the sensor 9, and the body movement of the user M measured by the body motion measuring sensor of the sensor 9. For example, the control unit 60 determines the sleep depth of the user M from at least one of breathing, heartbeat, and body movement.

As an example, the control unit 60 includes a roll-over measuring unit 61 for measuring roll-over, a sleep depth determination unit 62 for determining sleep depth, and a sleep data storage unit 63 for storing data including sleep depth as functional components. The device control unit 65 for controlling the operation of the devices (for example, the light emitting unit 4, the vibrating unit 5, and the heat generating unit 6) constituting the pillow 1 and a notification unit 66 for notifying various information are provided.

The roll-over measuring unit 61 measures, for example, the roll-over of the user M from the body movement of the user M measured by the sensor 9. For example, the turnover measuring unit 61 measures the number of times the user M turns over at bedtime. As a specific example, the rollover measuring unit 61 may measure the time and number of times the user M lies on his back, the time and number of times the user M sleeps sideways, and the time and number of times the user M lies down.

The sleep depth determination unit 62 determines, for example, the sleep depth of the sleeping user M. For example, the sleep depth determination unit 62 determines the sleep depth of the user M from at least one of the number of turns measured by the rollover measuring unit 61 and the breathing and heartbeat of the user M measured by the sensor 9. To do. As an example, the sleep depth determination unit 62 may determine that the sleep depth of the user M is deep when the number of times of turning over is equal to or less than a predetermined number of times.

Further, the sleep depth determination unit 62 may determine that the sleep depth of the user M is shallow when at least one of breathing and heartbeat is a predetermined number of times or more. The sleep depth determination unit 62 determines, for example, the sleep depth of the user M in five stages of 0 (REM sleep), 1, 2, 3, and 4. In this case, the larger the value of the sleep depth determined by the sleep depth determination unit 62, the deeper the sleep depth. For example, the sleep depth "4" is the deepest and "0" is the shallowest.

The sleep data storage unit 63 stores, for example, sleep depth data determined by the sleep depth determination unit 62. The sleep data storage unit 63 may store data on the sleep state other than the sleep depth. The device control unit 65 controls the operation of each device of the pillow 1 according to the sleep depth of the user M determined by the sleep depth determination unit 62. For example, the device control unit 65 may control the operation of at least one of the light emitting unit 4, the vibrating unit 5, and the heat generating unit 6 of the pillow 1 according to the sleep depth of the user M.

In this way, by controlling at least one of the light emitting unit 4, the vibrating unit 5, and the heat generating unit 6 of the pillow 1 according to the sleep depth of the user M, by at least one of visual, vibration, and temperature means. It is possible to optimize the sleeping environment of the user M. As a specific example, when the user M suffers from poor circulation and the sleep depth of the user M is shallow, the device control unit 65 may control the heat generating unit 6 to heat the pillow 1. Further, as an example, the device control unit 65 may be linked with the temperature sensor 8d that measures the temperature inside the bed of the bedding 8, and when the temperature measured by the temperature sensor 8d is equal to or higher than a predetermined value, the heat generating unit 6 May be stopped.

The configuration of the control unit 60 is not limited to the configuration including the above-mentioned roll-over measuring unit 61, sleep depth determination unit 62, sleep data storage unit 63, and device control unit 65, and can be appropriately changed. The control unit 60 includes, for example, a notification unit 66 that notifies the information terminal 70 of the sleep depth determined by the sleep depth determination unit 62. Further, the control unit 60 may include a sleep state estimation unit that estimates sleep state data other than the sleep depth, and the notification unit 66 notifies the information terminal 70 of sleep state data other than the sleep depth. You may.

The information terminal 70 includes, for example, a wake-up time setting unit 71 and a display unit 72. As an example, the display unit 72 is a display of a mobile terminal including a smartphone and a tablet, and the sleep depth determined by the sleep depth determination unit 62 or the data related to the sleep state stored in the sleep data storage unit 63 is displayed on the display unit 72. It may be displayed in.

The wake-up time setting unit 71 is an application that can set the wake-up time, and the wake-up time setting unit 71 sets a desired wake-up time by the user M. The wake-up time set in the wake-up time setting unit 71 is stored in, for example, the sleep data storage unit 63. In the present embodiment, the device control unit 65 may control the operation of the light emitting unit 4, the vibrating unit 5, and the heat generating unit 6 of the pillow 1 based on the wake-up time set in the wake-up time setting unit 71.

Next, an example of the sleep state control method according to the present embodiment will be described with reference to the flowchart shown in FIG. FIG. 6 shows an example of each step of controlling the sleep state of the user M by using the sleep state control system 50 according to the present embodiment. The series of steps of FIG. 6 is executed by, for example, the control unit 60. In the following description of FIG. 6, an example will be described in which the user M falls asleep at 23:00 and the user M wakes up at 6 o'clock.

First, the user M sets the wake-up time in the wake-up time setting unit 71 of the information terminal 70 (step S1, the step of setting the wake-up time). At this time, the wake-up time set in the wake-up time setting unit 71 may be stored in the sleep data storage unit 63 of the control unit 60, for example. For example, the time when the wake-up time is set in the wake-up time setting unit 71 may be set as the sleep-onset time (sleep-onset time), and the sleep-onset time may be stored in the sleep data storage unit 63. Then, the user M falls asleep (step S2).

When the user M falls asleep, the control unit 60 starts acquiring the sleep state of the user M by the sensor 9 of the bedding 8 (step S3, step of acquiring the sleep state). At this time, the sleep depth determination unit 62 acquires the sleep state of the user M via the sensor 9 of the bedding 8 and determines the sleep depth of the user M from the sleep state. Then, the device control unit 65 outputs a control signal to the light emitting unit 4 and the vibrating unit 5 via the communication unit 1n of the pillow 1, emits light from the light emitting unit 4 (light emitting unit 4a when falling asleep), and generates heat by the heat generating unit 6. (Step S4, step of emitting light and generating heat).

The light emitted from the light emitting unit 4 and the heat generated by the heat generating unit 6 are generated for a certain period of time from, for example, the sleep onset time (sleep onset time). The fixed time is, for example, 10 minutes or more and 30 minutes or less, but can be changed as appropriate. For example, during the certain period of time, the heat generating unit 6 heats the pillow 1 so as to reach a preset temperature set in the switch 7. The light emitting unit 4 changes the brightness of the light with the passage of time while emitting warm-colored light, and gradually reduces the brightness with the passage of time.

After the certain time has elapsed from the sleep onset time, the device control unit 65 stops the light emission of the light emitting unit 4 and the heat generation of the heat generating unit 6 (step S5, a step of stopping the light emitting and heat generation). For example, when the sleep onset time is 23:00 and the fixed time is 15 minutes, light emission by the light emitting unit 4 and heat generation by the heat generating unit 6 start from 23:00, and the light emitting unit 4 starts to generate heat at 23:15. Light emission and heat generation by the heat generating unit 6 are stopped.

After the user M falls asleep and both the light emitting unit 4 and the heat generating unit 6 are stopped, it is determined whether or not the time is before the wake-up time (step S6, whether or not the wake-up time is before the predetermined time). Step to determine whether The predetermined time is, for example, 10 minutes or more and 30 minutes or less, but can be changed as appropriate. For example, when the wake-up time is 6 o'clock and the predetermined time is 20 minutes, "a predetermined time before the wake-up time" is 5:40. If it is determined that the time is not before the wake-up time, the process continues to step S6. If it is determined in step S6 that the time has come before the wake-up time, the process proceeds to step S7.

In step S7, it is determined whether or not the sleep depth of the user M determined by the sleep depth determination unit 62 is shallower than a predetermined threshold value (step S7, step of determining the sleep depth). The "predetermined threshold value" is a value that serves as a reference for determining whether or not the user's sleep depth is suitable for awakening. For example, the sleep depth "that is the boundary value between REM sleep and non-REM sleep". 1 ".

In this case, it is determined whether or not the sleep depth determined by the sleep depth determination unit 62 is shallower than "1" (non-REM sleep), and if it is determined that the sleep depth is not shallower than "1", step S7 continues. Move to. On the other hand, when it is determined that the sleep depth is shallower than "1" (REM sleep), the process proceeds to step S8. However, the value of the above-mentioned "predetermined threshold value" is not limited to the sleep depth "1" and can be changed as appropriate.

As an example, if the sleep depth becomes shallower than the predetermined threshold value at 5:50 after 5:40, which is "a predetermined time before the wake-up time", the process proceeds to step S8 at 5:50. Since the user M wakes up at 5:50 when the sleep becomes light, the sleep time of the user M who falls asleep at 23:00 is 6 hours and 50 minutes.

In step S8, the device control unit 65 outputs a control signal to the wake-up means 10 (each of the light emitting unit 4, the vibrating unit 5 and the heat generating unit 6) via the communication unit 1n of the pillow 1, and the light emitting unit 4 (light emitting when wakes up). Light is emitted from the part 4b), vibration is performed by the vibrating part 5, and heat is generated by the heat generating part 6 (step of emitting light, vibrating and generating heat). The light emitted from the light emitting unit 4, the vibration by the vibrating unit 5, and the heat generated by the heat generating unit 6 may be stopped after a few minutes, or may be continued to be executed until the user M stops the switch 7.

At this time, the light emitting unit 4 gradually increases the brightness of the light with the passage of time while emitting pale light, the vibrating unit 5 gradually increases the intensity of the vibration, and the heat generating unit 6 gradually increases the amount of heat generated. You may have more. Further, the color and brightness of the light from the light emitting unit 4, the intensity of vibration of the vibrating unit 5, and the amount of heat generated by the heat generating unit 6 may be constant. As described above, the mode of operation of the light emitting unit 4, the vibrating unit 5, and the heat generating unit 6 can be appropriately changed and is not particularly limited.

As described above, the sleep state control system 50 according to the present embodiment includes a bedding 8 with a sensor 9 for measuring the sleep state of the user M, a pillow 1 provided with a wake-up means 10 inside the side land 2, and a user. It is provided with a sleep depth determination unit 62 that determines the sleep depth of the user M from the sleep state of M. Then, the wake-up means 10 operates when the set wake-up time (for example, 6 o'clock) or before the wake-up time and the sleep depth becomes shallower than a predetermined threshold value (for example, 5:50). Therefore, the user M can wake up at a desired time or earlier than the desired time by operating the wake-up means 10 before the set wake-up time or the wake-up time. Further, the user M can comfortably wake up in a state where the sleep depth is shallow by operating the wake-up means 10 when the sleep depth is shallower than a predetermined threshold value.

Further, a wake-up time setting unit 71 for setting the wake-up time is further provided, and the light emitting unit 4 is set after the wake-up time is set in the wake-up time setting unit 71 (for example, when falling asleep) and in the wake-up time setting unit 71. The light may be emitted during the wake-up time, and the vibrating unit 5 may vibrate at the time set by the wake-up time setting unit 71. In this case, the light emitting unit 4 emits light after the wake-up time is set, so that the user M can be invited to a comfortable sleep. Further, the light emitting unit 4 emits light at the time set in the wake-up time setting unit 71, and the vibrating unit 5 further vibrates, so that the user M can be reliably woken up at the set wake-up time.

The pillow 1 and the sleep state control system 50 according to the present disclosure have been described above. However, the pillow and sleep state control system according to the present invention are not limited to the contents of the above-described embodiments, and can be appropriately changed as long as the gist described in each claim is not changed. That is, the shape, size and material of the pillow, the function of each part of the sleep state control system, and the content and order of each step of the sleep state control method can be appropriately changed without departing from the above gist.

For example, in the above-described embodiment, the pillow 1 which is a body pillow having a thunder shape as a whole has been described. However, as shown in FIG. 7, for example, the pillow may be a dolphin-shaped body pillow 81 extending in one direction D1. As an example, the body pillow 81 is located at the linear abdomen 82 facing the abdomen of the user M, the head 83 located at one end of the abdomen 82 in one direction D1, and the other end of the abdomen 82 in one direction D1. It may be provided with a tail portion 84 to be used. Further, the body pillow 81 includes a dorsal fin portion 85 on the opposite side of the abdomen 82 in the width direction D2, and an arm portion 86 located on the tail portion 84 side of the dorsal fin portion 85 and facing the arm of the user M. May be good. Like the body pillow 81, the shape of the pillow according to the present invention can be changed as appropriate.

Further, in the above-described embodiment, an example in which the wake-up time setting unit 71 is provided in the information terminal 70 has been described. However, the pillow may include a wake-up time setting unit, and the arrangement position and arrangement mode of the wake-up time setting unit can be changed as appropriate. Further, in the above-described embodiment, the vibration unit 5 including two motors 5a that operate by receiving electric power is built in the pillow 1, and the heat generating unit 6 that is a heater including one heat-sensitive wire is incorporated in the pillow 1. An example of being built in was explained. However, the types of the vibrating part and the heat generating part can be changed as appropriate.

Further, in the above-described embodiment, the sleep onset means 20 including the light emitting unit 4 and the heat generating unit 6 and the wake-up means 10 including the light emitting unit 4, the vibrating unit 5 and the heat generating unit 6 have been described. However, the configurations of the means for falling asleep and the means for waking up can be changed as appropriate. For example, each of the sleep-onset means and the wake-up means may include only one of the light emitting unit 4, the vibrating unit 5, and the heat generating unit 6. Further, the pillow may be a pillow in which the heat generating portion 6 is omitted, or a pillow in which either the wake-up means 10 or the sleep-onset means 20 is omitted.

Further, in the above-described embodiment, the pillow 1 which is a body pillow has been described. However, the pillow according to the present invention may be a pillow other than a body pillow. For example, the pillow according to the present invention may be a nap cushion. In this case, if the wake-up time is set in the wake-up means of the nap cushion, the wake-up means operates at the wake-up time, so that it is possible to wake up comfortably from the nap.
