  However, in the conventional configuration described above, control must be performed by a specific control device in order to heat and cool the shape memory material. In addition, since the control is performed regardless of the state of the body, for example, the user is awakened when driving while sleeping, and thus there is a strong sense of discomfort such that a feeling of deep sleep cannot be obtained.

  The present invention solves the above-described problem, and estimates the sleep depth from the vibration information of the bedding, deforms the shape memory element based on the set time, and gives a stimulus to the body to wake up without discomfort. It is aimed.

  In order to solve the above-mentioned problem, the present invention includes a biological information sensor incorporated in a bedding, a driving unit that deforms the bedding, and a control device that operates the driving unit based on a signal from the biological information sensor. Was designed to act as awakening by stimulating the body by deforming the bedding. Therefore, the sleep state is detected by the biological information sensor, and the body is stimulated so as to be awakened based on the sleep state.

  According to the present invention, the body information is detected from the biological information sensor built in the bedding, the sleep depth is shallow, and the shape memory element is controlled to awaken by stimulating the body in the vicinity of the set time. A refreshing awakening can be realized.

  A first invention includes a biological information sensor built in the bedding, a driving unit that deforms the bedding, and a control device that operates the driving unit in response to a signal from the biological information sensor, and the driving unit deforms the bedding. Therefore, it is possible to give a stimulus to awaken the body according to a sleep state.

  In the second invention, the driving means is built in the pillow and stimulates the heads to tilt alternately. Therefore, the head can be stimulated and awakened.

  In the third invention, the biological information sensor is a vibration sensor. The sleep state was detected by vibration. By detecting the movement of the body with the vibration sensor, you can know the depth of sleep.

  According to a fourth aspect of the present invention, the control device includes a time notification device, and the control device activates the driving means when a predetermined signal is received from the vibration sensor in the vicinity of a predetermined set time set in the time notification device. I did it. Therefore, since the stimulation is given when the sleep depth is shallow, a refreshing awakening can be realized.

  The health bedding of the first embodiment of the present invention will be described below with reference to FIGS.

  As shown in FIG. 1, a bed pad 7 as a bedding and a plurality of sheet-like shape memory elements 8 arranged in parallel with the body 9 on the bed pad 7 in contact with the human body to realize a temperature transmission means. . Here, one shape memory element 8 is arranged in the center of the bed pad 7, and two shape memory elements 8 are arranged symmetrically on both sides thereof. And it was set as the structure which had the length from shoulder 10 vicinity of the body 9 to foot 11 vicinity. Further, as shown in FIG. 2, the shape memory element 8 is stored so as to be deformed into a wavy shape when a temperature near body temperature is reached.

  According to the above configuration, when the body 9 sleeps on the bed pad 7, the temperature in the bed 12 rises to near body temperature. The shape memory element 8 in contact with the body 9 is deformed into a stored wavy shape when the temperature is transmitted and reaches a predetermined temperature. Here, the wavy shape creates a space 13 in the bed and new air enters from outside the bed. Then, the temperature in the bed 12 is lowered by the new air, and the temperature of the shape memory element 8 is lowered. As a result, the shape memory element 8 is released from the stored shape, and the wavy shape becomes a linear shape due to the load of the body 9 and the comforter 14, and the space in the bed is lost. When the temperature rises again, the above operation is repeated.

  As described above, the shape memory element automatically repeats deformation according to the temperature of the body, so that the temperature in the bed can be maintained at an appropriate temperature. Since a sheet-like shape memory element is used, the sheet is deformed in a direction perpendicular to the bed pad surface, so that this operation can be reliably performed without shifting the deformation direction.

  In addition, since the body is pressurized with the convex portion 15 of the wavy shape memory element 8, there is an acupressure effect, and the body is stimulated by receiving the pressure, and the bed is turned over to avoid it, thereby preventing bed slipping. There is also the effect. This is a temperature gradient generated in the left-right direction from the center as shown in FIG. 3, and when the shape memory element is deformed with a different degree of deformation, the shape is most deformed at the center. As a result, the body is deformed into a shape that can be easily turned over to the left or right, and a superior bed slip prevention effect can be obtained. In addition, since the shape memory element is arranged from the shoulder to the foot in parallel with the body, even if the bed pad is turned up and shifted from the foot, the shape memory element is deformed into a wavy shape so that the pad reaches the foot. There is an effect that can be recovered to the spread state.

  Next, a second embodiment will be described with reference to FIGS. Parts having the same structure and the same function as those of the first embodiment are denoted by the same reference numerals, detailed description thereof is omitted, and different parts will be mainly described.

  As shown in FIG. 4, a metal foil plate 16 as a heat transfer element disposed in a portion in contact with the body 9 and a shape memory element 8 as a driving device disposed around a bed pad 17 as a bedding, The metal foil plate 16 and the shape memory element 8 are connected to transmit heat to the shape memory element 8. As a result, the shape memory element 8 is deformed so that the periphery of the bedding can be moved up and down.

  In such a configuration, when the body sleeps on the bedding, the temperature in the bed rises to near body temperature. Then, the temperature is transmitted to the metal foil plate in contact with the body, and further transmitted to the shape memory element connected to the metal foil plate. The shape memory element is deformed into a memorized wavy shape when a predetermined temperature is set. Here, the wavy shape results in a wavy shape around the bedding, and new air enters the bed from the space 18 created. Then, the temperature in the bed is lowered by the new air, and the temperature of the shape memory element is lowered. As a result, the shape memory element is released from the memorized shape, and the wave shape becomes a linear shape due to the load of the bedding, so that there is no exchange of air, the temperature rises again, and the above operation is repeated. . Here, the metal foil plate is provided so as to be in contact with the abdomen of the shape memory element when it is deformed, so that the deformation is smoothly performed. Further, since the futon can be lifted up and down without a control device, the temperature in the bed can be maintained at an appropriate temperature without disturbing sleep.

  Next, a third embodiment will be described with reference to FIGS. Parts having the same structure and the same function as those of the first embodiment are denoted by the same reference numerals, detailed description thereof is omitted, and different parts will be mainly described.

  As shown in FIGS. 6 and 7, a bed mat 19 as a bedding and a shape memory element 20 having a shape memory 20 stored in a height H2 higher than the height H1 of the bed mat 19 are provided in the bed mat 19. did. Here, 21 is a mat spring, 22 is a bed pad, and 23 is a sleeper's body.

  In such a configuration, since the bed mat 19 is covered with the comforter 14 surrounding the body 23, the bed mat 19 also rises in the same manner as the temperature rise in the bed 24. Since the temperature of the space inside the bed mat 25 similarly rises, the shape memory element 20 installed inside also rises in temperature. That is, the temperature transmission means is realized in the entire bedding including the heat retaining function of the comforter 14. Then, when the temperature is close to the body temperature, the shape memory element is deformed in the direction in which the mat height H1 is increased as a result of the deformation to the memorized shape, so that the height of the bed mat is increased. Then, new air enters the bed mat from the vent 27 provided with the one-way valve 26, and the temperature is lowered. As a result, the temperature of the shape memory element is lowered and the shape stored is freed to return to the original height by the spring force. Then, the temperature starts to rise again, and the above operation is repeated. At this time, the air in the mat is replaced at the same time, and the air in the bed is also changed, so that an abnormal rise in temperature can be prevented and an appropriate temperature can be maintained. Further, by replacing the air in the mat, the mat has a dehumidifying effect, and has the effect of preventing the occurrence of mold and corrosion. Here, the one-way valve 26 is attached to the side surface of the bed mat in a direction in which air enters the inside of the bed mat from the outside, and is configured to efficiently enter new air. And the air which approached is set as the structure which the air approachs into the bed by being gradually discharged | emitted from the whole mat | matte, without escaping from the vent hole 27. FIG. Thereby, the temperature in the bed can be kept at an appropriate temperature.

  Next, a fourth embodiment will be described with reference to FIGS. Parts having the same structure and the same function as those of the first embodiment are denoted by the same reference numerals, detailed description thereof is omitted, and different parts will be mainly described.

  As shown in FIGS. 8 and 9, shape memory elements 28A, 28B, and 28C built in a bed pad 27 as a bedding, and a microphone 29 that is a snoring detection device as a body biological information sensor using the bed pad 27; And a control device 30 that sequentially drives the shape memory elements 28A, 28B, and 28C in accordance with a signal from the microphone 29. Here, 31 is a microphone amplifier.

  In such a configuration, a sound near the bedding is detected by the microphone 29, and the control device 30 determines whether the sound is snoring. And if it is determined that it is a snoring sound, electricity supply to the shape memory element 28 will be started. By this energization, the shape memory element 28 starts to rise in temperature and is deformed into a memorized shape when it reaches a predetermined temperature. This shape memory element 28 is memorized in the direction in which the spring shape expands at a temperature near body temperature, and is deformed so as to stimulate the body. The stimulation causes snoring to stop if the depth of sleep decreases or the degree of arousal increases.

  In this way, by controlling the shape memory element based on the biological information, the unhealthy sleep state can be changed and improved into a healthy sleep state. In addition, since a shape memory element is used for the drive unit, drive noise is not generated, and it is not necessary to bother the person sleeping next to it. Then, as shown in FIG. 10, the acupressure effect on the back surface can also be obtained by disposing the bed pad so as to expand and contract in the vertical direction. Furthermore, as shown in FIG. 11, instead of simultaneously controlling the shape memory elements 28A, 28B, and 28C, a massage effect can be obtained by controlling the order of 28A → 28B → 28C in order to make the body undulate. . It is also possible to set the massage interval to a comfortable interval by setting the time timer.

  Next, a fifth embodiment will be described with reference to FIGS. Parts having the same structure and the same function as those of the fourth embodiment are denoted by the same reference numerals, detailed description thereof is omitted, and different parts will be mainly described.

  As shown in FIGS. 12 and 13, shape memory elements 32A, 32B, and 32C built in a bed pad 27 as a bedding, a chest motion sensor 33 that is a respiratory detection device as a biological information sensor, and the chest motion sensor 33 And a control device 34 for driving the shape memory elements 32A, 32B, and 32C in accordance with the signal from. The control device 34 is configured to assist the respiratory motion of the human body 35 by sequentially driving the shape memory elements 32A, 32B, and 32C in a predetermined order according to the signal of the chest motion sensor 33. Here, 36 is a chest motion sensor amplifier.

  In such a configuration, the shape memory elements 32A, 32B, and 32C are controlled in accordance with the signal of the chest motion sensor 33 as shown in FIG. That is, the breathing motion can be assisted by deforming the shape memory element 32 into a shape that is sequentially stored in accordance with every breath taken by the chest. First, the back portion is lifted by the shape memory element 32A, and then the shoulder portion and the abdominal portion after Δt time are lifted by the shape memory elements 32B and 32C, respectively. The flowchart is shown in FIG. 15, and the shape of the shape memory element when deformed is shown in FIG. In addition, the occurrence of symptoms of sleep apnea such that breathing motion stops can be determined by a signal from the chest motion sensor. If it is determined that the breathing has stopped, there is an effect that the breathing can be resumed by controlling the shape memory element to assist the breathing exercise. Since it is driven by the shape memory element, there is no driving noise, and the respiratory motion can be assisted without disturbing sleep. Moreover, since it controls in synchronization with biological information, it can be performed without discomfort.

  Next, a sixth embodiment will be described with reference to FIGS. Parts having the same structure and the same function as those of the first embodiment are denoted by the same reference numerals, detailed description thereof is omitted, and different parts will be mainly described.

  As shown in FIG. 17, a bed pad 38 as a first bedding incorporating a vibration sensor 37 as a biological information sensor, a pillow 40 as a second bedding incorporating shape memory elements 39A and 39B, and the shape A control device 41 that drives the storage elements 39A and 39B is provided. The control device 41 includes a time notification device 42. The control device 42 operates when a predetermined signal is received from the vibration sensor 37 in the vicinity of a predetermined set time set in the time notification device 42. The configuration.

  In such a configuration, the signal from the vibration sensor 37 during sleep is approximately as shown in FIG. That is, when the person is resting during sleep, the signal from the vibration sensor is hardly detected. However, when turning over, a very large signal is generated. When this signal is detected exceeding a predetermined threshold, it is estimated that the sleep has become shallow. Then, if it is within 30 minutes before and after the set time, the shape memory element is driven by the control device so that the sleeper is awakened. For example, as shown in FIG. 19, two shape memory elements are incorporated in a pillow and deformed into a shape alternately stored by the control device, so that the head 43 receives an alternating tilt and leads to awakening. Can do it.

  As described above, by using the shape memory element, it is possible to get up without causing trouble to a person sleeping next to there without driving noise. Moreover, it is possible to wake up refreshingly by estimating and waking up when the sleep depth is shallow with the vibration sensor.
