, Bearings 16 and 17 having a center axis at a position eccentric with respect to the first rotation shaft 50 are mounted, and a pair of swing members 18 and 19 are fixed to the bearings 16 and 17, respectively. The pair of massagers 10a, 10b are attached to the outer circumference of the swing members 18, 19 via arms 20, 21 as first connecting members, respectively. A pair of rods 2 serving as second connecting members are provided on the opposite sides of the swing members 18 and 19 from the mounting positions of the arms 20 and 21.
Each end of each of the rods 2 and 23 is movably attached to the rod 2.
The other ends of 2 and 23 are movably attached to the outer peripheral portions of the bearing bands 24 and 25. The bearing bands 24 and 25 include a pair of third rotating shafts 26 having an axis in a direction intersecting the axial direction of the first rotating shaft 50.
27 are mounted on bearings 28 and 29 whose center positions are eccentric with respect to the axes of the third rotating shafts 26 and 27. Therefore, the swing members 18 and 19 are connected to the third rotating shafts 26 and 27 via the rods 22 and 23 and the bearing bands 24 and 25. The eccentric drive member described in the claims includes the bearing bands 24 and 25 and the bearings 28 and 29.

The third rotating shafts 26 and 27 are connected to the frame 1
The gears 38, 39 are rotatably supported by bearings 53, 54 provided on a frame 52 provided between 4 and 15, project from the frame 52, and are fixed to the ends thereof. The gears 38, 39 are, for example, motors 44a, 44
gears 40 and 41 fixed to the rotating shaft b. With the above configuration, the motors 44a, 4
4b can be rotated simultaneously or individually to achieve a third
The rotating shafts 26 and 27 are simultaneously or individually rotated, and the massagers 10a and 10b perform a corresponding rubbing operation.

On the other hand, the driving mechanism 5 includes the frames 14, 1
5, a second rotation shaft 51 for adjusting the distance is arranged in parallel with the first rotation shaft 50 of the massagers 10a and 10b, and a motor 55 for driving the rotation shaft is provided. The motor 55 is bidirectionally rotatable, and its rotation is converted by the motion converting mechanism 56 in the axial direction of the second rotating shaft 51. A first screw portion 57 and a second screw portion 58 which are opposite to each other are formed on the left and right sides of the second rotary shaft 51 near the center thereof. The first screw portion 57 penetrates one end of the adjusting member 30 in which an internal screw that meshes with the screw of the first screw portion 57 is formed, and the second screw portion 58 meshes with the screw of the second screw portion 58. It passes through one end of the adjusting member 31 in which a matching internal screw is formed. At the other end of each of the adjustment members 30 and 31,
The first rotating shaft 50 penetrates in common, and the adjusting member 3
Reference numerals 0 and 31 are configured to be movable in the circumferential direction and the axial direction with respect to the first rotation shaft 50. Further, the adjusting member 30,
31 is the first rotating shaft 5 with respect to the swing members 18 and 19.
The first rotating shaft 50 is configured to be mutually displaceable in the circumferential direction of 0 and fixed along the axial direction of the first rotating shaft 50.

Accordingly, when the motor 55 is rotated in a predetermined direction and the second rotating shaft 51 is rotated in one direction, the adjusting member 3 is rotated.
The reference numerals 0 and 31 are supported by the first rotating shaft 50 and move in the mutually approaching direction. Thereby, the rocking members 18 and 19 and the massagers 10a and 10b also move in directions approaching each other. On the other hand, when the motor 55 is rotated in the reverse direction and the second rotating shaft 51 is rotated in the other direction, the adjusting members 30 and 31 are supported by the first rotating shaft 50 and move in directions away from each other. Thereby, the rocking members 18 and 19 and the massager 10
a and 10b also move in directions away from each other.
In this way, it is possible to adjust the position of the massage operation performed by the massagers 10a and 10b on the patient at an arbitrary interval.

At this time, since a pair of eccentric driving members related to the hitting operation are arranged so as to be orthogonal to the axial direction of the first rotary shaft 50 for driving the kneading operation, as shown in FIG. Swing members 18 and 19 for the first rotation shaft 50
The eccentric drive member associated with the hitting operation, even if moved along the axial direction of
7 only need to rotate in the circumferential direction.

The operation of the rubbing machine 1 according to this embodiment will be described below with reference to FIGS. In the following description, the hitting operation will be described. When performing the massage, the patient adjusts the interval between the massagers 10a and 10b to the second rotation shaft 51.
Is adjusted by operating a switch for controlling the rotation of the motor 55 for driving the motor. After that, the control switch is operated to select whether to use the massagers 10a and 10b on one side, to use one of the massagers 10a and 10b in the case of one side, and to use both the massagers 10a and 10b. And set. Thereafter, when the rubbing operation is started, the third rotation shafts 26 and 27 are rotationally driven according to this control by appropriately controlling the rotation start timing, rotation direction, rotation speed, and the like of the motors 44a and 44b. . When the third rotation shafts 26 and 27 rotate, the bearing bands 24 and 25 make orbital movements around the third rotation shafts 26 and 27, respectively. This allows
The rods 22 and 23 reciprocate periodically in a direction substantially along the axis thereof, and the swing members 18 and 19 perform reciprocating angular displacement motions around the first rotation shaft 50. Thereby, the massagers 10a and 10b perform a beating operation on the patient at the set intervals and rotations.

When performing the massaging operation of the massaging operation, the third rotating shafts 26 and 27 are stopped, and the first rotating shaft 50 is driven to rotate. When the first rotation shaft 50 rotates, the swing members 18 and 19 revolve around the first rotation shaft 50, but the swing members 18 and 19 are connected to the third rotation shafts 26 and 27. Therefore, the massagers 10a and 10b
The distance between the mounting positions of the rods 8 and 19 to the rods 22 and 23 and the axis of the first rotary shaft 50 and the rods 2 of the rocking members 18 and 19
Circumferential movement is performed with a movement amount proportional to the ratio between the position of attachment to the members 2 and 23 and the distance between the massagers 10a and 10b. Thereby, the massage operation is performed on the patient.

As described above, in the rubbing machine 1 of this embodiment, each of the massagers 10a and 10b can perform any independent operation independently, and various rubbing operations are realized. Thereby, a sufficient treatment effect can be obtained for the patient, and the operation quality of the rubbing machine 1 can be significantly improved.

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

[0022]

As described above, in the rubbing machine according to the present invention, when the adjusting member, the swinging member and the massager move in the width direction due to the rotation of the second rotating shaft, the eccentric driving member becomes the first eccentric driving member. The eccentric drive member does not move in the axial direction of the first rotating shaft but swings in accordance with the movement in the width direction because the eccentric driving member is mounted on a pair of third rotating shafts orthogonal to the axial direction of the rotating shaft. The second connecting member connected to the member floats, and the movement of the eccentric drive member is transmitted to the swinging member by the second connecting member. Therefore,
The rubbing machine of the present invention, even when the massager performs width adjustment during a treatment operation such as a beating operation or a kneading operation, the eccentric drive member that performs the beating operation does not participate in the movement accompanying the width adjustment, so the beating operation is performed. The width adjustment can be performed smoothly because the adjustment member and the swinging member can be moved smoothly, as well as smoothly.

Further, since the pair of eccentric driving members related to the hitting operation are arranged so as to be orthogonal to the axial direction of the first rotating shaft for driving the kneading operation, the rocking member for the kneading operation is the first member. The eccentric drive member associated with the hitting operation, even if moved along the axial direction of the rotation shaft, drives the hitting operation in the third direction.
It is only necessary to rotate in the circumferential direction of the rotating shaft, and it does not move together with the swinging member, so that the operating sound becomes quiet.

Further, since the hitting mechanism has a pair of eccentric driving members independent for each of the left and right massagers, various hitting treatments can be performed.

Further, due to its configuration, it is possible to add or delete the width adjusting function of the massager, and it is easy to develop various specifications of the model.

Furthermore, it is also possible to provide independent drive sources for the third rotating shaft, and by controlling the rotation of the drive sources, it is possible to perform various rubbing operations with respect to the hitting operation, thereby providing a sufficient therapeutic effect. Can be played,
Operation quality can be remarkably improved.
