Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a roller pine surge machine, and more specifically, a roller arm having a pine surge roller mounted on its tip swings back and forth on a vertical plane. This invention relates to a roller pine surge machine that provides a pine surge effect to the user.

[Conventional technology]

In conventional roller pine surge machines, the roller arm is oscillated by mechanical means such as an eccentric cam, an eccentric disk, a guide plate having a predetermined curved unevenness, and the like.

[Problem that the invention seeks to solve]

In the above conventional technology, since mechanical means are used to drive the roller arm to swing, the pine surge by the pine surge roller can only obtain a pine surge with a certain limited movement, and the selection range of pine surge is narrow. The disadvantage is that the structure for swinging is complicated.

[Means for solving problems]

The present invention aims to eliminate the above-mentioned drawbacks of the prior art.
Motor 1 whose speed-torque characteristic curve has drooping characteristics
2, the roller arm 11 is driven, and the input current or voltage to the motor 12 is controlled by the amplitude,
data selection means 18 storing various characteristic curves with different periods and waveforms; data reading means 19;
The microcomputer 20 may include a microcomputer 20 consisting of a D/A converter 20, or a microcomputer 20 having a data fine adjustment means 22 interposed between the data reading means 19 and the D/A converter 20. This is the structure.

[Effect]

To explain the operation of the present invention, one end of the roller arm 11 is directly connected to the drive shaft of the motor 12, which has a drooping speed/torque curve, so that the roller is pressed by the body pressure on the back and the motor stops rotating. When,
The roller pressure against the back caused by the motor torque at the maximum point of the motor torque curve (at the time of starting torque) becomes stationary when it is balanced with the body pressure. When the torque decreases, the roller is pushed back by the body pressure, and conversely, when the torque increases, the roller overcomes the body pressure and moves forward.

Therefore, by appropriately controlling the input current or voltage to the motor 12, it is possible to provide a pine surge machine in which the strength of the roller pressure can be controlled to suit the user's preference.

Therefore, if a control function is added by diversifying the input current or voltage to the motor 12 through microcomputer control, it becomes possible to control the type and strength of the pine surge.

That is, the data selection means 18 of the microcomputer 17 stores patterns with different types of pine surge (distinguishing between acupressure, tapping, and vibration), amplitude (strength), period (pitch), and waveform (degree of pressure change). A characteristic curve that should function is determined by the data selection means, and the characteristic curve is determined by the data reading means 19, the D/A converter 20, the motor control circuit 21, or between the data reading means 19 and the D/A converter 20. By interposing the belt fine adjustment means 22 in the motor 12
is driven by a microcomputer arm, and the rolling pressure of the pine surge roller 10 can be changed based on a memorized characteristic curve.

〔Example〕

To explain an embodiment in which the present invention is implemented in a chair-type pine surge machine, referring to FIGS. , inserting the guide hole 6 of the lifting frame 5 into the guide rod 3, screwing the screw hole 7 with the screw rod 4, and rotating the screw rod 4 in forward and reverse directions via the deceleration mechanism 9 by the reversible motor 8 for lifting and lowering. The elevating frame 5 is raised and lowered. The vertical movement range of the elevating frame 5 is regulated by the upper limit position sensor _S1 and the lower limit position sensor _S2 . Referring to FIGS. 4 and 5, one base of a pair of roller arms 11 on which two pine surge rollers 10, 10 are mounted is fixed to an output shaft 13 of a motor 12 fixed to a lifting frame 5. The other base of the roller arm 11 is pivoted to the lifting frame 5 by a shaft 14, and the pins 15 and 16 are connected to the lifting frame 5.
is fixed to restrict the swing range of the roller arm 11 in the longitudinal direction on the vertical plane. The motor 12
In this method, a speed-torque characteristic curve having a drooping characteristic (for example, the characteristic curve shown in FIG. 6) is used, the input current or voltage to the motor 12 is controlled by a microcomputer, and the rolling pressure of the pine surge roller 10 against the body is maintained at a predetermined level. The amplitude, waveform, and period of the signal are varied based on a selected characteristic curve. The motor 12 can be any type of motor, regardless of whether it is for direct current or alternating current, as long as it has a speed-torque curve with a drooping characteristic. Note that the motor may be a motor with a reduction gear. Furthermore, as the motor deceleration means, a gear train mechanism as shown in FIG. 10, for example, can be used, and other gear train mechanisms that are already generally known may of course be used. Reference numeral 18 denotes data selection means, and this data selection means 18, for example, selects the acupressure waveform A1,
If characteristic curves such as A2, A3, beating waveforms B1, B2 in Fig. 8, and vibration waveforms C1, C2, C3 in Fig. 9 are stored, any one of the characteristic curves can be selected. The user can choose. In the first invention shown in FIG. 1, the microcomputer controls the motor 12 by reading out the characteristic curve selected by the data selection means 18 by the data reading means 19, and transmitting the signal from the D/A converter 20 to the motor control circuit. 21 and is supplied to the motor 12 to control the input current or input voltage to the motor 12, and in the second invention, the characteristics selected in the data selection means 18 After reading out the curve by the data reading means 19 and slightly changing the data by the data fine adjustment means 22, the signal is given to the D/A converter 20, and then from the D/A converter 20 to the motor control circuit 2.
1 to a motor 12 to control the input current or voltage to the motor 12. The microcomputer 17 can also function as a control means for normal rotation, reverse rotation, stop, speed change, etc. of the motor 8 for lifting and lowering.

When using the roller pine surge machine of the present invention, the user first selects the type of pine surge of shiatsu, tapping, and vibration using the data selection means 18 (for example, A1 shown in FIGS. 7 to 9, A2, A3, B1, B2, C1, C2, C
3)). Then, the motor 12 is set so that the rolling pressure of the selected type of pine surge or the rolling pressure slightly modified therefrom is generated.
The pine surge roller 10 provides a predetermined pine surge action to the user. Note that the roller pine surge machine of the present invention can be used not only as a chair type but also as a bed type. Furthermore, by omitting the threaded rod, guide rod, etc., and installing the motor 12 on the inside bottom of a small handheld case, it can also be used as a handheld pine surger.

〔Effect of the invention〕

The present invention uses a motor whose speed-torque characteristic curve has a drooping characteristic to operate a pine surge roller in the front-rear direction on a vertical plane, and the amplitude, period, and waveform of the characteristic curve of the input current or input voltage of the motor are Since the selection is made by computer control, the amplitude (strength), period (pitch), and waveform (degree of pressure change) of the rolling pressure of the pine surge roller can be easily and quickly adjusted to the user's preference. Furthermore, in the first invention, the user was able to select the pine surge that he or she preferred from among various patterns of pine surge, but in the second invention, the user felt that the feel of the pine surge according to the selected pattern was somewhat lacking. At times, the user may want to make the contact strength of the roller a little stronger.
On the contrary, it can be adjusted to be a little weaker, and the structure is generally simple and can be provided at low cost.
