EXAMPLES Examples of the present invention will be described below. FIG. 1 shows a block diagram of a first embodiment of the present invention, and FIG. 2 shows a schematic view of a sleeping apparatus. 1a to 1i are body movement detecting means, 2 is signal converting means, 3 is determining means, and 4 is output means. here,
The output means 4 is an audio signal generator. Signal conversion means 2
The filter 5 and the amplifier 6 are built in the storage unit 7, and the storage unit 7 and the comparison unit 8 are built in the determination unit 3. A bed mat 10 in which the body movement detecting means 1a to 1p are incorporated is placed on the bed 9. Reference numeral 11 is a speaker section of the output means 4. The body movement detecting means 1 is a thin film-like flexible piezoelectric element made of polyvinylidene fluoride (PVDF) and can detect vibration.

The operation of the above configuration will be described below. Suppose that a person sleeping in bed 9 has an intention to turn over. When a sleeping person moves to try to turn over, the body movement detecting means 1a to 1p detect the vibration caused by the body movement,
A voltage change occurs. The signal converting means 2 passes through the filter 5 and the amplifier 6 and is converted into a body motion signal. The storage unit 7 of the determination unit 3 stores the output distribution pattern of the body motion signal that is a precursor of a typical motion. When the body movement signal is output from the signal conversion unit 2, the comparison unit 8 compares it with the distribution pattern of the storage unit 7. When the output distribution pattern of the body movement signal is similar, the determination unit 3 outputs a signal corresponding to the operation determined to be similar. Output means 4
Then, according to the signal sent as a result of being judged to roll over,
A sound is emitted from the speaker 11 such as "Turn over."

With the above operation, it is possible to judge the body motion distribution pattern that occurs when an attempt is made to make a motion and inform the caregiver of the intention of the care receiver to make a motion. Even if the person is performing other work, it is possible to understand the movement of the cared person and give consideration to safety. The distribution pattern of the storage unit 8 and the output unit 4
If the content of the voice is variable, even if the person has a specific propensity such as a dementia symptom, it is possible to detect the body movement and notify the caregiver.

Next, a second embodiment of the present invention will be described. FIG. 3 is a block diagram of the second embodiment of the present invention, and FIG.
A schematic diagram of the sleeping apparatus of the present embodiment is shown in FIG. 1a and 1b are body movement detecting means, 2 is signal converting means, 3 is judging means, 12
Is a reclining bed. Reference numeral 12a is a back support plate that supports the upper body during reclining, and 12b is a substrate that supports the lower limbs. A filter 5 and an amplifier 6 are built in the signal converting means 2 of 1a and 1b.

The operation of the above configuration will be described below. A sleeping person on the reclining bed 12 tries to get up.
Then, the sleeping person tries to raise his / her upper body near the waist, as shown in FIG.
The movement of the center of gravity is started by supporting the arm around the body movement detecting means 1a, 1b. This body movement detecting means 1
The a and 1b are arranged at positions where body movements are always caused when the upper body is raised. The body movement detecting means 1a, 1b detect the vibration caused by the body movement, and are converted into a body movement signal through the filter 5 and the amplifier 6 in the signal converting means 2.
The determination unit 3 distinguishes whether the body movement is an attempt to raise the upper body or a vibration caused by another body movement. Threshold Va
When it is determined that the body movement signal exceeding the above is output from both the body movement detecting means 1a and 1b, the signal is output as the body movement that attempts to wake up the upper body. Reclining bed 12
In response to this signal, the person lifts 12a and reclines to assist the operation of raising the upper body. That is, the reclining function is not driven unless a constant body movement is generated. If the sleeping person cannot raise his / her upper body by reclining, the body movement signal is detected again by the body movement detecting means 1a, 1b. Then, the reclining function is driven by receiving the signal of the output means. In this way, the body movement of the sleeping person is constantly fed back, so that reclining can be driven according to the movement of the sleeping person.

With the above-described operation, the reclining bed is started to be driven by the body motion generated when the sleeping person tries to get up, so that the timing for assisting the sleeping person to get up is improved. Further, since reclining can be driven according to the body movement of the sleeping person, the sleeping person does not have to be subjected to an unreasonable and burdensome movement. further,
The bed is not driven unless the sleeping person moves his / her body with the intention of waking up, which leads to the continuous independence of the bed, which also helps prevent physical weakness and maintains muscle strength.

Further, when the body movement detecting means 1 is arranged on the body side portion of the mat of the posture changing bed or on the mat of the foot supporting plate of the gudge bed, the operation of turning over and raising the leg is detected and immediately. The bed function that assists the movement is driven.

[0017]

As described above, the sleeping device of the present invention has the following effects. Since the intention of the cared person during sleep can be transmitted to the caregiver without the need to speak, it can be used by persons with disabilities.

Further, since it is a device that assists the care giver's motion, the care giver's will can be respected,
It is also possible to maintain an independent willingness to make a motion by itself.

Further, since it is necessary to maintain the muscular strength capable of starting the motion for starting the motion, it is possible to prevent the weakening of the physical function.

Further, since the movement assistance can be adjusted to the degree of recovery of muscle strength, it can be used for training such as rehabilitation.
