By operating the power switch 59 in this state, the massage operation starts after performing the initial self-check.

  Next, the air pressure control method of each embodiment of the present invention implemented by the control unit (CPU) 55 will be described.

  First, in the control method of mode 1 shown in FIG. 3, basically, a plurality of pressurization set values A1 (for example, 70 mmHg, 100 mmHg, and 130 mmHg) previously set and stored as default values are selected and set by the selection key 57. , Pressurization → pressure holding → massage mode (pressurization / decompression cycle, pressurization / depressurization pattern) in the case of repeatedly performing depressurization with a predetermined reduction width a plurality of times in one short cycle. It is also possible to select and set a plurality of other pressures so that they can be selected and set.In addition, since there are individual differences in the massage effect, the user can adjust the pressure value, pressure holding time ( It is also possible to set and change the pressure reduction value arbitrarily, and to provide a pulse detection means to synchronize the short period (t4) with the pulse, or to apply one cycle of pressurization and pressure reduction. The mode 4 control method may be synchronized with an integral multiple of the beat.

  In the control method of mode 2 shown in FIG. 3, the first and second cycles are set as one pressurization / depressurization pattern. Specifically, in the first cycle, automatic pressurization is performed from the atmospheric pressure to the pressurization set value A1, and pressurization and depressurization are determined within a predetermined decompression width a1 based on the pressurization set value A1. Repeat with a short cycle as many times. After repeating the predetermined number of times, the pressure is once released to the atmosphere and the first cycle is completed. When the first cycle is completed, in the next second cycle, automatic pressurization is performed up to a pressurization set value A2 larger than the previous time, and pressurization and depressurization are performed with a predetermined depressurization width a2 based on the pressurization set value A2. Repeat with a short period of the number of times determined in. After repeating the predetermined number of times, the pressure is once released to the atmosphere, and one cycle is completed. In this case, all the pressures may be released to the atmosphere when the pressure is reduced.

  In the control method of mode 3 shown in FIG. 3, the first to third cycles are set as one pressurization / depressurization pattern. Specifically, in the first cycle, automatic pressurization is performed from the atmospheric pressure to the pressurization set value A1, and pressurization and depressurization are determined within a predetermined decompression width a1 based on the pressurization set value A1. Repeat with a short cycle as many times. After repeating the predetermined number of times, the pressure is once released to the atmosphere and the first cycle is completed. When the first cycle is completed, in the next second cycle, automatic pressurization is performed up to a pressurization set value A2 larger than the previous time, and pressurization and depressurization are performed with a predetermined depressurization width a2 based on the pressurization set value A2. Repeat with a short period of the number of times determined in. After repeating the predetermined number of times, the pressure is once released to the atmosphere, and one cycle is completed. When the second cycle is completed, in the next third cycle, automatic pressurization is performed up to a pressurization set value A3 larger than the previous time, and pressurization and depressurization are performed with a predetermined depressurization width a3 based on the pressurization set value A3. Repeat with a short period of the number of times determined in. After repeating the predetermined number of times, the pressure is once released to the atmosphere, and one cycle is completed. In this case, all the pressures may be released to the atmosphere when the pressure is reduced. The pressure setting value is not limited to three levels, and may be four or more levels. In addition, by automatically storing the set optimum pressurization / decompression pattern, it becomes possible to perform the pattern next time.

By controlling the air pressure as described above, it is possible to eliminate the habituation of massage, and a comfortable massage feeling can be continuously obtained by the pressurization / decompression pattern suitable for the individual user. In addition, since the belt 101 contracts when swelling is reduced, the user can visually recognize the effect very easily during the massage operation by looking at the scale 101d.
As described above, the description has been given based on the example. However, the present invention is not limited to the above-described example, and the pressurization / decompression pattern can be appropriately changed.
