The other terminals of the motors 19a to 19f are supplied with a DC voltage converted by the DC adapter 36. A part of the DC voltage converted by the DC adapter 36 is supplied to the control unit 29 via a constant voltage circuit 37. Therefore, each of the motors 19a to 19f is driven to rotate in accordance with the pulse width and cycle of the pulse voltage output from the motor selector 34.

As shown in FIG. 8, the changeover switch 26 can be set to any one of an off position, a loose position, and a hit position. When the position of “relax” or “hit” is selected by the changeover switch 26, the selection signal is input to the frequency selection section 31. The frequency selector 31 selects the frequency of the pulse voltage for driving each of the motors 19a to 19f according to the selected position, and inputs the signal to the motor selector 34.

In the course selection by the position / course selection switch 28, by selecting the courses 1 to 4, a signal for operating each of the vibrators 8a to 8f is input to the motor selection section 34 based on a predetermined program. . An example of the operation of each of the vibrators 8a to 8f based on a predetermined program is shown in the time charts of FIGS.

That is, when course 1 is selected, FIG.
When the first to fourth vibrators 8a to 8d are operated to massage the upper body of the user who lies on the mattress device as shown in FIG. 11 and the course 2 is selected, the third to sixth vibrators 8a to 8d are displayed as shown in FIG. The vibrators 8c to 8f operate to massage the lower body of the user. When course 3 shown in FIG. 12 and course 4 shown in FIG. 13 are selected,

In the course 4, the selection signal of the course 4 is directly input from the position / course selection switch 28 to the pulse width setting unit 32 regardless of the setting of the strength adjustment switch 27. The intensity of the massage is controlled based on the intensity programmed in advance.

The operation of the course 4 is stopped in 15 minutes by a timer 33 provided in the control unit 29. Within 15 minutes, the massage intensity is set to "strong" for the first 5 minutes. The intensity is pre-programmed to run "medium" for the next 5 minutes and "weak" for the remaining 5 minutes.

FIGS. 14 and 15 show an example of the selection of the frequency by the changeover switch 26 and the setting of the pulse width by the intensity control switch 27. FIG. As shown in FIG.
When the changeover switch 26 is set to "relax", the cycle of the pulse voltage P for driving the vibrator is set to 15 ms, that is, the frequency is set to about 66 Hz.

FIG. 14A shows that the strength adjustment switch 27 is set to "strong" so that the pulse width of the pulse voltage P becomes 3.5 ms.
FIG. 14B shows a case where the strength adjustment switch 27 is set to “weak” so that the pulse width of the pulse voltage P becomes 1.0 ms.

When a predetermined vibrator is operated in such a setting, the period of the vibration generated by the vibrator according to the period of the pulse voltage P is shortened, so that the user may receive a massage in a state where the body is loosened. it can.

When the changeover switch 26 is set to "hit", the period of the pulse voltage P for driving the vibrator is 180 ms, that is, the frequency is about 5.5, as shown in FIG.
Hz.

FIG. 15A shows a case where the strength adjustment switch 27 is set to "strong" so that the pulse width of the pulse voltage P is 60 ms. FIG. 15B shows a case where the pulse width of the pulse voltage P is 10 ms. In this case, the strength adjustment switch 27 is set to “weak”.

When a predetermined vibrator is operated in such a setting, the period of the vibration generated by the vibrator in accordance with the period of the pulse voltage P becomes long, so that the user is in a state where the body is hit by intermittent vibration. You can get a massage.

FIGS. 16A and 16B and FIGS.
(B) illustrates the relationship between the cycle T and pulse width W of the pulse voltage P and the number of revolutions of the motor of the vibrator. In other words, this indicates that the number of revolutions of the motor increases within the range of the pulse width of the pulse voltage P, and the number of revolutions decreases when the application of the pulse voltage is released as time passes.

More specifically, FIG. 16A shows a case where a pulse voltage having a pulse width W ₁ and a period T ₁ is applied to the motor.
As shown in FIG. 6B, the next pulse voltage is applied when the rotation speed becomes almost zero.

[0051] Since the motor generates the greatest acceleration when starting to rotate, by applying a next pulse voltage at the time when the speed becomes substantially zero, almost the maximum acceleration at intervals of motor cycle T ₁ Will happen. Thereby, the user can receive a tapping massage.

FIG. 17A shows that the motor has a pulse width W ₂ ,
In the case of applying a pulse voltage of period T ₂ to the motor, the motor which rotates by the application of the pulse voltage, FIG. 17
As shown in (b), the next pulse voltage is applied when the rotation speed does not become 0.

Therefore, the motor rotates without intermittently generating a large acceleration as at the start of rotation.
The user receives the massage with the vibration having little change in intensity. That is, the user can receive a massage in which the body is relaxed.

The cushion body 1 of the mattress device is constituted by laminating the acupressure layer 3 on the core layer 2. The core material layer 2 is formed into a hard cotton by pressing a cotton fiber into a layer and entangled with an adhesive so as to maintain a predetermined cushioning property and to have a structure having air permeability and moisture absorption / dissipation properties. I have.

If the hardness of the core layer 2 is set to such a degree that the user does not feel uncomfortable without making the hardness too soft, the vibrator 8a held by the core layer 2
When 8f is operated, the vibrations of these vibrators are less likely to be absorbed by the core layer 2, so that the vibrations can be efficiently transmitted to the acupressure layer 3.

The acupressure layer 3 is processed relatively hard and has a large number of hemispherical projections 3a.
Therefore, the vibration of the vibrators 8 a to 8 f is efficiently transmitted to the acupressure layer 3, and the projection 3 a provided on the acupressure layer 3 can enhance the massage effect of pressing the body of the user.

Moreover, since the core layer 2 is made of hard cotton, the vibration of the vibrators 8a to 8f does not propagate widely. Therefore, the acupressure layer 3 locally vibrates strongly, and accordingly, the body of the user is also strongly massaged locally.

The core layer 2 has not only cushioning properties but also air permeability and moisture absorption / dissipation properties. Therefore, it is difficult for moisture to accumulate inside the core material layer 2, so that even when used for a long time, generation of mold on the lower surface side can be prevented.

The present invention is not limited to the above embodiment. For example, the control of the vibrator by the control device can select between a massage having a sense of tapping the frequency of the pulse voltage and a massage having a sense of loosening. However, only the massage having a sense of tapping may be performed.

[0060]

According to the first aspect of the present invention, the vibration of the vibrator provided on the cushion body can be variously controlled by the control device. Can be received at the site where

According to the second aspect of the present invention, the intensity of vibration can be changed by changing the pulse width of the pulse voltage for driving the motor of the vibrator by the pulse width setting section, and the frequency of the pulse voltage can be changed by the frequency setting section. By changing, the interval (frequency) of vibration can be changed.

Therefore, a high massage effect can be obtained by the protrusions of the acupressure layer vibrating due to vibrations having different strengths and intervals.

According to the third aspect of the present invention, the operation of the plurality of vibrators provided on the cushion body can be set by the operation setting section.

Therefore, the user can receive a massage by an operation according to his preference.

According to the fourth aspect of the present invention, the plurality of vibrators provided at predetermined positions can be selectively operated by the operation setting section.

Therefore, the user can receive a massage at a desired part of the body.

According to the invention of claim 5, a plurality of vibrators can be sequentially operated according to a predetermined program.

Therefore, the user can receive a massage in various variations.

According to the sixth aspect of the present invention, the cushioning property is improved by forming the core material layer of the cushion body with hard cotton.
The acupressure layer laminated on the core layer was formed by thermally compressing a foamed elastic material so as to have air permeability and moisture absorption / dissipation properties.

[0070] Therefore, the cushion body can effectively propagate the vibration of the vibrator to the acupressure layer by the cushioning property and enhance the massage effect, and can prevent the moisture from being trapped by the breathability and moisture absorption and diffusion property. .
The acupressure layer can be provided with hardness by being formed by thermal compression, so that the acupressure effect by the protrusions formed thereon can be enhanced.
