DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair-type rubbing machine, for example.

[0002]

2. Description of the Related Art FIG. 14 is a view for explaining a conventional rubbing operation. 2. Description of the Related Art In a chair-shaped rubbing machine, a driving mechanism for performing a rubbing operation is stored in a backrest portion of the chair. The drive mechanism is provided with a pair of massagers 81 and 82, and by driving a motor arranged in the drive mechanism, a rotary shaft connected to the motor rotates. A pair of eccentric members are mounted on the rotating shaft at positions eccentric with respect to the rotating shaft. The eccentric positions of the respective eccentric members are determined so as to be out of phase by 180 degrees with respect to the rotation direction of the rotating shaft. Therefore, when the rotation shaft rotates, the respective eccentric members perform a swinging operation in a state of being 180 degrees out of phase with each other, whereby the respective massagers 81 and 82 reciprocate with respect to the patient, respectively. 14 (1), and so on.

[0003]

In the anomaly machine having the above-described structure, the operation of the massagers 81 and 82 is limited to the alternate operation. Therefore, the pair of massagers 81 and 82 are shown in FIG. 14 (2). When performing a kneading operation that is an operation of periodically sandwiching such a treatment site, it is difficult to effectively sandwich the treatment site because the pair of massagers 81 and 82 alternately contact the treatment site. However, there is a problem that it is difficult to obtain a sufficient lubrication effect. The same applies to the case where the pair of massaging members 81 and 82 perform a beating operation. Since the rubbing operation is limited to the alternate lapping operation, it is difficult to obtain a sufficient rubbing effect. Even when the pair of massagers 81, 82 perform a back muscle stretching operation (hereinafter, rolling operation) reciprocating in parallel along the spine of the patient, the pair of massagers 81, 82 are used.
However, since the position of the patient with respect to the patient is displaced, there is a problem that a sufficient effect of stretching the back cannot be realized.

[0004] Furthermore, in the above-mentioned conventional rubbing machine,
The aforementioned alternating operation is always performed at a constant speed. As a result, there is a problem that the rubbing operation is monotonous and has little change, and the patient is easily bored with the treatment, and the usability is low in this respect.

[0005] The invention of claim 1 has been made to solve the above-mentioned technical problem, and an object of the invention is to change the operating speed of a pair of massagers to diversify treatment modes and to improve usability. To provide an anomaly machine capable of improving

According to the invention of claims 2 and 3, together with the object of claim 1, it is possible to provide an rubbing machine in which the operation of the massager can be switched between the alternate operation and the simultaneous operation, and the configuration is simplified. It is.

[0007]

According to the first aspect of the present invention, the pair of massagers perform the reciprocating lubrication operation on the patient. The massager is driven to reciprocate with respect to the patient by rotating the motor, and performs a massaging operation. At this time, the control device changes the rotation speed of the motor stepwise over a plurality of predetermined rotation speeds,
In addition, one cycle of the rotation speed change is repeated a plurality of times.

In this manner, when performing the massaging operation, the operation speed is changed over a plurality of stages, so that the massaging operation is diversified, and the situation in which the patient gets tired of the treatment is prevented, and the usability is improved. You.

According to a second aspect of the present invention, in the first aspect of the invention, when the motor is rotated in one of the two directions of rotation, the rotation is transmitted to the first rotating shaft and the second rotating shaft is rotated. The rotation is transmitted to the shaft via the phase switching device, and the first and second rotation shafts are respectively rotated. here,
Each massager is connected to a pair of swinging members via an arm, and each swinging member is rotatably mounted around an eccentric position with respect to each rotation axis. Each eccentric position of each rocking member is determined at a position that is either in phase or in phase with respect to the rotation direction of each rotation shaft. Accordingly, each swing member periodically performs a swing operation for each rotation of each rotation shaft. Here, in the present invention,
The control means switches the rotation direction of the motor to a direction opposite to the rotation direction at the end of the alternating or simultaneous massaging operation performed by the pair of massagers on the patient.

[0010] When the rotation direction of the motor is switched in the direction opposite to the rotation direction in the alternating lubrication operation, the phase switching device
The rotation of the second rotation shaft is stopped during a period in which the first rotation shaft rotates in a direction corresponding to the rotation direction after the motor is switched by half a rotation thereof. Therefore, when the rotation direction of the motor is switched in the reverse direction, the second rotating shaft is stopped and the first rotating shaft is rotated by half a rotation thereof. With respect to the rotation direction, the phase is switched to the phase opposite to that of the previous operation.

According to this, in the massaging machine of the present invention, when the massaging operation of the massaging is a simultaneous massaging massaging operation after the completion of the alternating massaging operation, a pair of massaging masses which have been operated alternately in the operation up to that time. Can be switched to operate simultaneously by simply switching the rotation direction of the motor. When shifting from the simultaneous lubrication operation to the alternate lubrication operation, the rotation direction of the motor may be rotated in a direction opposite to the rotation direction during the simultaneous lubrication operation. Therefore, while using the above-described operation mode in which the operation speed changes, the user can simultaneously hit the user, use the pair of massagers at the same position, perform the simultaneous tapping operation, the simultaneous massage operation, or the simultaneous rotation. A ring operation can be performed. Further, switching between the simultaneous lubrication operation and the alternate lubrication operation can be easily performed only by alternately switching the rotation direction of the motor. Thus, while the operation speed is changed by the pair of massagers, the alternate operation or the simultaneous operation can be appropriately selected to rub the treatment site effectively, and the rubbing effect can be improved. In addition, even in the rolling operation, the positions of the pair of massagers with respect to the patient are the same, so that the back stretching effect can be improved.

According to the second aspect of the present invention, there is provided the lubricating machine according to the second aspect, wherein the hollow portion and the hollow portion are formed in the vicinity of one end in the axial direction of the second rotating shaft over a predetermined angle in the circumferential direction. An opening communicating with the outside is formed, and the phase switching device is inserted into the hollow portion so that one end portion is displaceable in the axial direction and the circumferential direction, and a screw is formed near the other end portion. A switching device comprising: a first pin projecting outward from the opening at an interval in the axial direction; and a second pin and a third pin disposed on both axial sides of the screw for preventing displacement in the axial direction. A shaft and the rotation of the motor are transmitted, the second rotation shaft is coaxially inserted so as to be displaceable in the circumferential direction and the axial direction, and the first rotating shaft is connected to one end in the axial direction at a predetermined angle in the circumferential direction. A first rotating member having a groove formed therein, A range in which the second rotary shaft is inserted coaxially and displaceably in the circumferential direction and the axial direction, and the first rotary member is opposed to the first rotary member; In the case of a configuration including a second rotating member having a second groove formed over the predetermined angle, the same is realized.

FIG. 9 shows the drive mechanism 5 performing an alternate tapping operation, and FIG. 10 shows the drive mechanism 5 performing a simultaneous tapping operation. When the alternate beating operation shown in FIG. 9 is performed, the rotating shaft 61 of the motor 60 rotates clockwise as viewed from the direction of arrow A in FIG. 9, whereby the gear 40 and the pulley 38 rotate counterclockwise. It is rotating in the direction. This rotation transmits the rotation in the same direction to the pulley 39 by the timing belt 41. By the rotation of the pulley 39, the pin 42 stored in the storage groove 56 of the pulley 39 is pressed against the wall of the clockwise end portion of the storage groove 56, and rotates in the clockwise direction. The switching shaft 72 to which is fixed also rotates in the same direction. The pin 42 presses the wall of the counterclockwise end of the opening 71 of the rotating shaft 27 to rotate the rotating shaft 27 in the same direction. At this time, the bearings 28 and 29 are set in mutually opposite phases as shown in FIG.

On the other hand, when the rubbing machine 1 performs the simultaneous beating operation as shown in FIG. 10, the rotating shaft 61 of the motor 60 rotates counterclockwise as viewed from the direction of arrow A in FIG. As a result, the gear 40 and the pulley 38 rotate clockwise. This rotation is performed by the timing belt 41.

The rotation of the switching shaft 72 to which the pin 42 is fixed also rotates in the same direction as the clockwise rotation by being pressed by the wall of the terminal end of the storage groove 46 in the clockwise direction. The pin 42 presses the wall at the clockwise end of the opening 71 of the rotating shaft 27 to rotate the rotating shaft 27 in the same direction. At this time, the bearings 28 and 29 are set in the same phase as shown in FIG.

At this time, the screw 73 near the tip of the switching shaft 72 and the slide wheel 47 are engaged with each other, and the switching shaft 72 is located at the right end position in FIG. 9 as shown in FIG. In contact with the contact piece 48, it rotates together with the slide wheel 47. Further, since the switching shaft 72 is located at the right end in FIG. 9, the pin 42 of the switching shaft 72 is in a state of being housed in the housing hole 47 of the cover 57.

Here, when the motor 60 rotates in the clockwise direction, the pulley 39 and the cover 57 rotate in the counterclockwise direction, and the pin 42 is relatively moved about 90 degrees in the storage hole 46.
When the cover 57 is rotated only by a degree,
The pin 42 comes into contact with the wall of the end portion in the counterclockwise direction of No. 6 and the pin 42 stored in the storage hole 46 of the cover 57 also rotates in the same direction. Switching shaft 72 to which pin 42 is fixed
Rotate in the same direction within the hollow portion 70 of the rotating shaft 27. When the pin 42 rotates through an angle of about 90 degrees within the opening 71 of the rotating shaft 27, the pin 42 abuts against the wall of the clockwise terminal end of the opening 71 of the rotating shaft 27 and rotates the rotating shaft 27. At this time, the switching shaft 72 is moved leftward by the engagement of the screw 73 and the screw 59 of the slide wheel 47, and the pin 42 is stored in the storage hole 56 of the pulley 39. At this time, the rotating shaft 26 has rotated about half a turn, and the massagers 10a, 10b
Is switched from the alternate tapping operation shown in FIG. 12 (1) to the same-phase simultaneous tapping operation shown in FIG. 12 (2).

On the other hand, an operation in which the simultaneous beating operation is switched to the alternate beating operation will be described. Output shaft 61 of motor 60
Will be described in the reverse direction, that is, the case where the clockwise rotation as viewed from the arrow A direction in FIG. When an operation changeover switch (not shown) provided in the rubbing machine 1 is operated, the control device 62 outputs a forward rotation signal S, and a gate signal is supplied to the triac 60. A drive current is supplied.

At this time, the output shaft 61 of the motor 60 rotates counterclockwise, and the pulley 39 rotates clockwise. At this time, the threaded portion 73 near the tip of the switching shaft 72 and the slide wheel 47 are engaged with each other, and the switching shaft 72 is located at the left end position in FIG.

9 is stored in the storage hole 56.

Here, when the motor 60 rotates in the counterclockwise direction, the pulley 39 and the cover 57 rotate in the clockwise direction, and the pin 42 moves relatively 90 degrees in the storage hole 39.
When the pulley 39 is rotated only by moving the
The pin 42 contacts the wall at the clockwise end of No. 6 and
The pin 42 stored in the storage hole 56 of the holder 39 also rotates in the same direction. The switching shaft 72 to which the pin 42 is fixed is
The rotary shaft 27 rotates in the same direction in the hollow portion 70. Pin 4
When the pin 2 is rotated through an angle of about 90 degrees in the opening 71 of the rotating shaft 27, the pin 42 comes into contact with the wall of the counterclockwise end of the opening 71 of the rotating shaft 27 and rotates the rotating shaft 27. At this time, the switching shaft 72 moves rightward by engagement of the screw 73 and the screw 59 of the slide wheel 47, and the pin 42 is stored in the storage hole 46 of the cover 57. At this time, the rotating shaft 27 has rotated about half a turn, and the massagers 10a, 10b
Is switched from the simultaneous tapping operation shown in FIG. 12 (2) to the alternate-phase tapping operation shown in FIG. 12 (1).

At this time, when the beating operation shown in FIGS. 12 (1) and 12 (2), the kneading operation shown in FIG. 12 (3) or the rolling operation described above is performed, the beating operation is alternately performed. The pair of massagers 10a and 10b
By simply switching the rotation directions of the two, it is possible to switch to operate simultaneously. Therefore, the hitting operation, the kneading operation, and the rolling operation can be performed using the pair of massagers 10a and 10b having the same position with respect to the patient. Thus, in the kneading operation, the treatment site can be effectively sandwiched between the pair of massaging elements 10a and 10b, and the lubrication effect can be improved. Further, even in the rolling operation, the pair of massagers 10a, 1
Since the position of 0b with respect to the patient is the same position, the effect of stretching the back muscles can be improved.

Further, in the rubbing machine 1 of this embodiment, FIG.
It is possible to adjust the speed of the hitting operation as shown in FIG. Under the control of the control device 62, the period T1
Then, the motor 60 and the like are rotated, and then the motor 6 is rotated at a speed V3 for a period T2, and further at a speed V3 for a period T3.
Rotate 0. With the operation period of the period T1 + T2 + T3 as one cycle, this cycle is repeated only for a predetermined rubbing operation. According to the experiment of the present inventor, in order to enhance the treatment effect, regarding the speed and the period, V2 = V / 2 (1) V3 = 0 (2) where V1 = 400 to 500 [ / Min] T2 = 2T1 (3) T3 = T1 (4) However, it was confirmed that if T1 = 1 [sec], it is optimal.

The pattern of such a speed change is programmed in the control device 62 and can be controlled by controlling the number of rotations by a speed signal from a pulse generator provided in the motor 60. In addition, the operation by the speed control produces an effect even by the conventional alternate hitting operation, but it has been confirmed that the simultaneous hitting operation described above is more effective.

As described above, in the rubbing machine 1 of this embodiment, the simultaneous operation and the alternate operation of the massagers 10a and 10b can be easily selected only by switching the rotation direction of the motor 60. Thereby, compared with the case of performing only one of the alternating operation and the simultaneous operation as in the related art, it is possible to realize various rubbing operations, increase the treatment effect, and significantly improve the operation quality. be able to.

The phase switching device 30 is connected to the rotating shaft 27.
Since it is configured integrally, the configuration can be simplified as compared with the case where the phase switching device is configured at a position different from the rotation shafts 26 and 27.

The present invention is not limited to the above embodiments, but includes a wide variety of modifications without departing from the spirit of the present invention.

[0039]

As described above, according to the first aspect of the present invention, the pair of massagers perform the reciprocating grooming operation on the patient. The massager is driven to reciprocate with respect to the patient by rotating the motor, and performs a massaging operation. At this time, the control device changes the rotation speed of the motor stepwise over a plurality of predetermined rotation speeds, and repeats one cycle of the change of the rotation speed a plurality of times.

As described above, when performing the massaging operation, the operation speed is changed in a plurality of steps, so that the massaging operation is diversified, and the situation in which the patient gets tired of the treatment is prevented, and the usability is improved. You.

According to the second and third aspects of the present invention, at the end of the alternating or simultaneous rubbing operation performed by the pair of massagers on the patient, the control means changes the rotation direction of the motor to the previous rotation direction. When the motor switches its rotation direction in the direction opposite to the rotation direction during the alternating lubrication operation, the phase switching device switches the first rotation shaft by half a rotation after the motor is switched. The rotation of the second rotation shaft is stopped during a period of rotation in a direction corresponding to the rotation direction. Therefore, when the rotation direction of the motor is switched in the reverse direction, the second rotating shaft is stopped and the first rotating shaft is rotated by half a rotation thereof.
With respect to the rotation direction of each rotation shaft, the phase is switched to a phase opposite to the phase of the operation so far.

Thus, in the massaging machine according to the present invention, when the massaging operation of the massaging is a simultaneous massaging massaging operation after the completion of the alternating massaging operation, a pair of massaging masses which have been operated alternately in the operation up to that time. Can be switched to operate simultaneously by simply switching the rotation direction of the motor. When shifting from the simultaneous lubrication operation to the alternate lubrication operation, the rotation direction of the motor may be rotated in a direction opposite to the rotation direction during the simultaneous lubrication operation. Therefore, while using the above-described operation mode in which the operation speed changes, the user can simultaneously hit the user, use the pair of massagers at the same position, perform the simultaneous tapping operation, the simultaneous massage operation, or the simultaneous rotation. A ring operation can be performed. Further, switching between the simultaneous lubrication operation and the alternate lubrication operation can be easily performed only by alternately switching the rotation direction of the motor. Thus, while the operation speed is changed by the pair of massagers, the alternate operation or the simultaneous operation can be appropriately selected to rub the treatment site effectively, and the rubbing effect can be improved. In addition, even in the rolling operation, the positions of the pair of massagers with respect to the patient are the same, so that the back stretching effect can be improved.
