Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massage machine for treating a shoulder or the like by reciprocating and rotating a treatment element.

[0002]

2. Description of the Related Art FIG. 2 shows a conventional massage machine. The massage machine shown in FIG. 2 includes a treatment element 3 provided at the tip of an arm (not shown), a built-in motor for reciprocating the treatment element 3, and a control circuit (not shown) for controlling the driving of the built-in motor. And a speed detector 6 for detecting the operation speed of the treatment element 3. The operation of the treatment element 3 is performed while the speed detection section 6 detects the operation speed that changes according to the load applied to the treatment element 3. It is controlled by a control circuit to keep the speed constant.

[0003]

In the above-mentioned conventional massage machine, however, the control circuit 4 automatically keeps the operating speed of the treatment element 3 constant, but treatment with the same rhythm is monotonous. At the same time, since the control factor for automatic control is speed, it is effective for the massage action of tapping, which exerts a massage effect according to the number of treatments, but exerts the massage effect by the power of treatment There is a problem that a sufficient massage effect and a satisfactory degree of satisfaction cannot be obtained with respect to a massage action of massaging as compared with a method of directly detecting and controlling the magnitude of a load.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a massage machine having a high massage effect and a high degree of satisfaction by detecting the magnitude of a load applied to a treatment element. It is in.

[0005]

According to a first aspect of the present invention, there is provided a massage machine, comprising: a motor; an arm reciprocating and rotating when driven by the motor; and a distal end of the arm. Treatment device, and a control circuit for controlling the drive of the motor, in a massage machine that treats the shoulder and the like by the operation of the treatment device, the inclination of the arm that changes depending on the magnitude of the load applied to the treatment device. A detector for detection is provided in the vicinity of the arm, and the operating speed of the treatment element is controlled by changing a motor voltage according to a detection signal detected by the detector.

Therefore, the magnitude of the load applied to the treatment element is directly detected, and the massage is performed based on the detected magnitude of the load. Can be valid.

[0007]

FIG. 1 shows a first embodiment according to the present invention.

[First Embodiment] FIGS. 1A and 1B are explanatory views schematically showing a first embodiment, in which FIG. 1A schematically shows the vicinity of an arm, and FIG. 1B is a circuit diagram.

The massage machine of this embodiment includes a motor 1, an arm 2 reciprocating and rotating when driven by the motor 1, a treatment element 3 provided at the tip of the arm 2, And a control circuit 4 for controlling the operation of the massager, and a detector for detecting the inclination of the arm 2 that changes according to the magnitude of the load applied to the massager 3 in a massage machine that treats the shoulder and the like by the operation of the massager 3 5 to arm 2
The operating speed of the treatment element 3 is controlled by changing the voltage of the motor 1 in accordance with a detection signal detected by the detector 5.

Next, the detection method will be described in detail. Here, a case will be described in which the arm 2 reciprocates on a circular arc about a certain point of the arm 2 as a rotation center. One point of the arm 2 or the treatment element 3 is set as a measurement point, and the inclination of the arm 2 (reference inclination) calculated from the measurement point when the treatment element 3 has no load (no load) and the position of the rotation center is reciprocated. It is stored in advance for each state point obtained by dividing the cycle at a certain time interval. When a load is applied to the treatment element 3, the position of the rotation center does not change, and only the measurement point moves. The measurement point moves on an arc that passes when there is no load because the rotation center is fixed. Therefore, the measurement at the time of load is limited to the measurement point only. Therefore, the inclination of the arm 2 is calculated from the position of the measurement point and the position of the rotation center measured when an actual load is applied, and the inclination of the arm 2 and the inclination of the arm 2 when there is no load (reference inclination) are calculated. By comparison, the magnitude of the load is detected from the difference in the inclination. Examples of the position of the measurement point include a method in which a light emitting element is provided at the measurement point and a light receiving element is provided on an arc on which the measurement point moves, but other measurement methods may be used.

Therefore, the magnitude of the load applied to the treatment element 3 is directly detected, and the massage is performed based on the detected magnitude of the load. Can be effective. In addition, since the control is performed with a constant speed and an inconstant speed, a massage with a higher degree of satisfaction can be performed as compared with a monotonous massage at a constant speed.

[0012]

As described above, the massage machine according to the first aspect of the present invention directly detects the magnitude of the load applied to the treatment element, and performs massage based on the detected magnitude of the load. In addition, the present invention is effective for the action of massaging which exerts a massage effect by the power of treatment, and it is possible to provide a massage machine having a high massage effect.
