  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the present invention may be described with specific examples, but the present invention is not limited to the following specific examples.

(Embodiment 1)
FIG. 1 shows a refresh device according to the first embodiment. Here, FIG. 1A is a side view, and FIG. 1B is a top view.

  First, the configuration of the refresh device 1A will be described.

  The refresh device 1A has a bed 2, a controller 3, an instruction input device 4, an illumination 5, and AV devices such as a television 6a and a content player 7 as a basic configuration.

  The bed 2 includes a bed main body 2a and a mattress 2b. The bed main body 2a is configured to be reclined so that the user 8 can take a relaxing posture. Further, the mattress 2b is equipped with a stretch function for extending the body muscle of the user 8, a pressing function for giving a finger pressure sensation to the user 8, and a vibration function for giving a vibration stimulus to the leg of the user 8. As a stretch function, for example, using an air bag and an air pump (not shown), air is sent from the air pump to the air bag and inflated to stretch the muscles of the body of the user 8 on the mattress 2b. Can do. Moreover, a massager can be used as a pressing function, and a vibrator can be used as a vibration function. Instead of the bed 2, a recliner chair equipped with a stretch function, a pressing function, and a vibration function may be used.

  The controller 3 can be provided inside the bed body 2a. The controller 3 controls the reclining of the bed main body 2a, the stretch function mounted on the mattress 2b, the pressing function and the vibration function, the lighting 5, the AV equipment such as the television 6a and the content player 7 in accordance with an instruction from the user 8. Prepare a nap environment for the user 8. In addition, the controller 3 is prepared with several types of programs adapted to the characteristics of the user 8, such as difficulty in falling asleep, light sleep, and poor awakening.

  The instruction input device 4 is provided in the vicinity of the pillow 9. A touch panel monitor can be employed as the instruction input device 4. When an instruction from the user 8 is input, the instruction input device 4 transmits the information to the controller 3.

  The lighting 5 is gradually darkened in order to relax the user 8 and lead to a sleep state, or gradually becomes bright in order to promote the user's awakening, and the user 8 has a high arousal level. In order to achieve this, light with high illuminance is illuminated.

  AV devices such as the TV 6a and the content player 7 play a natural image or relaxing music to promote the user's arousal in order to relax the user 8 and lead him to sleep. In order to realize a high degree of arousal, the video that the brain is likely to feel a stimulus, such as a video with particularly high brightness, a video with fast movement, a video with fast switching, or a refreshing environmental sound is reproduced. The content player 7 is accommodated in the TV stand 6b.

  Next, an example of the operation of the refresh device 1A will be described.

  When the program is started, the relaxation guiding means W operates and the relaxation period starts. The relaxation guiding means W relaxes the user 8 and leads to a sleep state. First, the bed body 2a is reclined so that the back of the user 8 is raised slightly, and the user 8 is maintained in a relaxing posture. The relaxable posture differs depending on the user, but generally, the reclining angle is set to 60 degrees. The illumination 5 is gradually darkened so as not to suppress the secretion of melatonin. In addition, AV devices such as the television 6a and the content player 7 reproduce natural images and relaxing music. Furthermore, the stretch function, the pressing function, and the vibration function mounted on the mattress 2b work. Specifically, the stretch function performs an operation as described above by injecting a little air in order into a plurality of airbags arranged at the end portion such as a calf using an air pump. The vibration function applies vibration stimulation to the user's 8 foot and relaxes the user 8. At this time, the vibration stimulus given to the user's 8 foot, the stimulus given to the user 8 by video and music, and the stimulus given to the user 8 by illumination are gradually attenuated. Note that the stretch function, the pressing function, and the vibration function do not stimulate the trunk portion (the head to the trunk portion) of the user 8 during the relaxation period.

  When the relaxation period ends, the sedation maintaining means X operates and the sedation maintenance period starts. The sedation maintenance means W maintains the sleep state of the user 8. The controller 3 as the control means V creates a state in which there is no stimulus other than background noise, and maintains a dark and quiet environment. Basically, the stretch function, vibration function and pressing function mounted on the mattress 2b are stopped, the illumination 5 is turned off, and playback of the AV device such as the television 6a and the content player 7 is stopped. In order to reduce the anxiety, a dim light may be left in the illumination 5. This dim light can reduce the horizontal illuminance near the knee of the user 8 to 30 lux or less.

  When the sedation maintenance period ends, the refresh stimulation means Y operates and the refresh period starts. The refresh stimulation means Y refreshes the user 8, raises the user's consciousness level, and leads the user 8 to awakening. The illumination 5 is gradually brightened, and the user 8 facial illuminance is gradually increased to 100 lux, preferably about 1000 lux at the time of waking up. In addition, AV devices such as the TV 6a and the content player 7 play images that the brain is likely to feel irritation, such as images with particularly high brightness, images with fast movement, images with fast screen changes, and refreshing environmental sounds. To do. Furthermore, the stretch function, the pressing function, and the vibration function mounted on the mattress 2b work. Specifically, as a stretch function, the back of the user 8 is lifted high by putting a lot of air into the air bag placed near the heart, such as the back of the user 8, using an air pump. The action of stretching the muscles is performed. Here, the finger pressure sensation stimulation by the pressing function and the vibration stimulation by the vibration function are given so as to gradually approach the trunk portion from the vicinity of the user's 8 toes. In addition, during the refresh period, the intensity of stimulation by lighting, stimulation by music or video, stimulation to stretch the muscle of the user 8 by the stretch function, acupressure stimulation by the pressing function and vibration stimulation by the vibration function are gradually increased. Also good. Furthermore, the stimulation function may be gradually increased during the refresh period. For example, at the initial stage of the refresh period, since the user 8 starts to awaken, only the music is stimulated so that the user 8 is not stressed. At the end of the refresh period, the user by the stretch function is used. The stimulation which stretches 8 muscles is given and the user 8 is fully awakened. Note that the functions of stimulation can be combined and operated as desired.

  When the refresh period ends and the wake-up time is reached, the wakefulness maintaining means Z is activated and the wakefulness maintaining period starts. The awakening maintenance means Z makes the user 8 realize a high arousal level. The illumination 5 illuminates light with high illuminance. Specifically, the user 8 facial illuminance is set to 1000 lux or more. In addition, AV devices such as the TV 6a and the content player 7 play images that the brain is likely to feel irritation, such as images with particularly high brightness, images with fast movement, images with fast screen changes, and refreshing environmental sounds. To do.

  When the awakening maintenance period ends, the program ends.

  Incidentally, the controller 3 as the control means V generally controls the relaxation period to 5 minutes, the sedation maintenance period to 10 minutes, the refresh period to 1 minute, and the wakefulness maintenance period to 4 minutes. It can also be controlled to be optimal in accordance with the characteristics of the user such as difficulty in falling asleep, shallow sleep, and poor awakening.

  Therefore, since the user 8 can take a nap efficiently, even if it is a short nap, the user 8 can sufficiently obtain a sense of arousal and can improve work processing ability.

(Embodiment 2)
FIG. 2 shows a refresh device according to the second embodiment. Here, FIG. 2A shows a side view, and FIG. 2B shows a top view.

  This embodiment is different from the first embodiment in that the refresh device 1B includes a biological sensor 10.

  The biological sensor 10 determines the sleep state of the user 8 in real time from biological signals such as heart rate and respiratory rate, and transmits the result to the controller 3. The biosensor 10 can be used in contact with the user 8 as a matter of course. However, the biosensor 10 can be used without being in contact with the user 8 so as not to cause discomfort. In this case, the biosensor 10 is disposed between the bed body 2a and the mattress 2b. The biosensor 10 can be separated from the user 8 by 20 to 40 cm. This corresponds to a typical mattress thickness. Moreover, if it is this distance, there will be little influence of the noise which the biosensor 10 detects.

  In addition to the instruction from the user 8, the controller 3 can recline the bed main body 2a according to the result of the sleep state of the user 8 determined by the biometric sensor 10, the stretch function mounted on the mattress 2b, the vibration function and the pressing function, The AV device such as the lighting 5, the television 6 a, and the content player 7 is controlled to prepare the nap environment for the user 8. For example, when the biometric sensor 10 detects the sleep of the user 8 while the stretch function is operating, the stretch function is stopped or when it is determined that the user 8 is about to go into deep sleep. Causes the stretch function to refresh the user 8.

  That is, the controller 3 as the control means V determines the length of the relaxation period, the length of the sedation maintenance period, the length of the refresh period, the length of the wakefulness maintenance period, according to the result of the sleep state of the user 8 determined by the biological sensor 10. Control the length. Specifically, when the biological sensor 10 detects the sleep of the user 8 during the relaxation period, the relaxation period is ended and the sedation maintenance period is started, or the user 8 is in the sedation maintenance period. If it is determined that the person is about to go into deep sleep, a refresh period is started. For example, when it is desired to take a nap only for a predetermined time, the length of the relaxation period and the length of the sedation maintenance period are set to predetermined lengths in advance, and the length of the refresh period and the length of the wakefulness maintenance period are set. Can be controlled according to the result of the sleep state of the user 8 determined by the biosensor 10.

  Therefore, since the user 8 can take a nap more efficiently, even if it is a short nap, it is possible to obtain a feeling of awakening more sufficiently and improve work processing ability.

(Embodiment 3)
FIG. 3 shows a refresh device according to the third embodiment. In the third embodiment, the refresh device is installed in the rear seat of the car 20.

  First, the configuration of the refresh device 1C will be described.

  The reclining seat 11 is configured to be reclined so that the user 8 can take a relaxing posture. In addition, the reclining seat 11 is equipped with a stretch function that stretches the muscles of the user 8, a pressing function that imparts a finger pressure sensation to the muscles and legs of the user 8, and a vibration function that imparts vibration stimulation. Specifically, as a stretch function, for example, by using an air bag 15 and an air pump (not shown), air is sent from the air pump to the air bag 15 to be inflated, whereby the user 8 on the reclining seat 11 is inflated. Can push up your body muscles. Moreover, the massager 16 can be used as a pressing function, and the vibrator 17 can be used as a vibration function.

  The controller 3 can be provided inside the reclining seat 11. The controller 3 controls the reclining of the reclining seat 11, the stretching function, the pressing function and the vibration function, the sleeping light 12 a, the awakening light 12 b, the AV device such as the television 6 a and the content player 7, and the sunshade 14 according to the instruction from the user 8. Then, the nap environment of the user 8 is prepared. In addition, the controller 3 is prepared with several types of programs adapted to the characteristics of the user 8, such as difficulty in falling asleep, light sleep, and poor awakening.

  The instruction input device 4 is provided in the vicinity of the user 8. A touch panel monitor can be employed as the instruction input device 4. When an instruction from the user 8 is input, the instruction input device 4 transmits the information to the controller 3.

  The sunshade 14 creates a dark sleepy environment by blocking outside light.

  The sleep light 12a is gradually darkened in order to relax the user 8 and lead to the sleep state, and the wake light 12b is gradually brightened or promoted to the user 8 in order to promote the user 8's awakening. In order to achieve a high degree of arousal, light with high illuminance is illuminated.

  AV devices such as the TV 6a and the content player 7 play a natural image or relaxing music to promote the user's arousal in order to relax the user 8 and lead him to sleep. In order to realize a high degree of arousal, the video that the brain is likely to feel a stimulus, such as a video with particularly high brightness, a video with fast movement, a video with fast switching, or a refreshing environmental sound is reproduced.

  Next, an example of the operation of the refresh device 1C will be described.

  When the program is started, the relaxation guiding means W operates and the relaxation period starts. The relaxation guiding means W relaxes the user 8 and leads to a sleep state. First, the reclining seat 11 tilts the back to an angle at which the user 8 can relax, reclines so that the legs are raised, and allows the user 8 to maintain a relaxing posture. The reclining angle can be set to a desired angle of the user 8. In addition, the sun shade 14 closes the shade to block outside light, creating a dark and sleepy environment. And the sleep illumination 12a becomes dark gradually so that the secretion of melatonin is not suppressed. In addition, AV devices such as the television 6a and the content player 7 reproduce natural images and relaxing music. Furthermore, the massager 16 and the vibrator 17 mounted on the leg part of the reclining seat 11 operate. In addition, as a pressing function, a plurality of airbags (not shown) may be arranged at the end of a calf or the like, and an air pump may be used to perform a sandwiching operation by injecting a little air in order. . And vibrator 17 gives vibration stimulus to user's 8 leg, and makes user 8 relax. At this time, the pressure stimulus, the vibration stimulus, the sound volume of the speaker 13, the illuminance of the sleep light 12a, and the like applied to the user 8's foot are gradually attenuated. In addition, the airbag 15, the massager 16, and the vibrator 17 do not give a stimulus to the trunk part (head to trunk part) of the user 8 during the relaxation period.

  When the relaxation period ends, the sedation maintaining means X operates and the sedation maintenance period starts. The sedation maintenance means W maintains the sleep state of the user 8. The controller 3 as the control means V creates a state in which there is no stimulus other than background noise, and maintains a dark and quiet environment. Basically, the air bag 15, the massager 16 and the vibrator 17 mounted on the reclining seat 11 are stopped, the sleep onset illumination 12a is turned off, and the reproduction of AV equipment such as the television 6a and the content player 7 is stopped. However, in order to reduce the anxiety of the user 8, a dim light may be left in the sleeping light 12a. This dim light can reduce the horizontal illuminance near the knee of the user 8 to 30 lux or less.

  When the sedation maintenance period ends, the refresh stimulation means Y operates and the refresh period starts. The refresh stimulation means Y refreshes the user 8, raises the user's consciousness level, and leads the user 8 to awakening. First, the awakening illumination 12b is gradually brightened, and the user's 8 facial illuminance is gradually increased to 100 lux, preferably about 1000 lux at the wake-up time. Also, from a little before the wake-up time, the music content for awakening is reproduced by the content player 7 and can be heard from the speaker 13. Further, the leg massager 16 and the vibrator 17 mounted on the reclining seat 11 are activated immediately before getting up. Here, the acupressure stimulation by the massager 16 and the vibration stimulation by the vibrator 17 are given so as to gradually approach the trunk from the vicinity of the toes of the user 8. During the refresh period, the volume from the speaker 13 gradually increases toward the wake-up time, and the massager 16 and the vibrator 17 gradually increase the stimulation. Further, the function of stimulation may be gradually increased during the refresh period. Note that the functions of stimulation can be combined and operated as desired.

  When the refresh period ends and the wake-up time is reached, the wakefulness maintaining means Z is activated and the wakefulness maintaining period starts. The awakening maintenance means Z makes the user 8 realize a high arousal level. The reclining seat 11 returns to the original angle and opens the sunshade 14, and the awakening illumination 12b illuminates the face of the user 8 with the maximum illuminance. Specifically, the awakening illumination 12b sets the user 8 facial illuminance to 1000 lux or more. AV devices such as the television 6a and the content player 7 reproduce images that the brain is likely to feel stimulation, for example, images with particularly high luminance, images with fast movement, images with fast screen switching, and refreshing environmental sounds. Further, the airbag 15 mounted on the reclining seat 11 is activated. Specifically, by using an air pump to put a lot of air into an air bag 15 placed near the heart, such as the back of the user 8, the back of the user 8 is lifted high, and muscles The operation of pushing up is performed.

  When the awakening maintenance period ends, the program ends.

  Incidentally, the controller 3 as the control means V generally controls the relaxation period to 5 minutes, the sedation maintenance period to 10 minutes, the refresh period to 1 minute, and the wakefulness maintenance period to 4 minutes. It can also be controlled to be optimal in accordance with the characteristics of the user such as difficulty in falling asleep, shallow sleep, and poor awakening.
