Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

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. A pair of massagers are connected to the drive mechanism, and by driving a motor arranged in the drive mechanism, the massagers perform a reciprocating motion, and perform a massaging operation such as a massaging operation or a hitting operation. . Further, in order to perform a massaging operation on a desired part of the patient sitting on the chair, a backrest portion of the chair is provided with an elevating mechanism for elevating and lowering a driving mechanism. In addition, an adjusting mechanism for adjusting an interval between the pair of massagers is provided.

[0003] As an example of the driving mechanism of the above-described rubbing machine, one having the following configuration is conceivable. In the drive mechanism, in order to perform a kneading operation, a pair of swash plate cams having a hexagonal cylindrical insertion hole are inserted through the first shaft into a hexagonal column-shaped first shaft rotated by the first motor. Each of the swash plate cams is attached, and a massager is provided at one end of each cam via an arm. The rotation of the first shaft causes the swash plate cam to swing, thereby causing the pair of massagers to perform an elliptical motion with respect to the patient sitting on the massager, thereby performing a massage operation. The other end of each of the pair of swash plate cams is attached to an eccentric cam, and the eccentric cam is attached to a second shaft. When the second shaft is driven to rotate by the second motor, the other ends of the pair of swash plate cams move up and down. Thereby, the massager attached to one end of the swash plate cam moves up and down to perform a hitting operation.

[0004] In the conventional rubbing machine, each of the swash plate cams is attached to the first shaft so that the phase of the operation of the massager is shifted from each other by 180 degrees. For this reason, regardless of the kneading operation or the hitting operation, each massaging member operates alternately at a fixed time interval.

[0005]

In the anomaly machine having the above-described structure, the operation of each massager is limited to the above-mentioned alternating operation. Operation in phase is not possible. The operation in this arbitrary phase is an operation in which, after one massager massages the patient, the other massager performs the massage operation at an arbitrary timing within one cycle of the movement of one massager. . Therefore, there is a case where a sufficient therapeutic effect may not be obtained due to the inability to perform the various grooming operations, and there is a problem that the operation quality is low.

[0006] The invention of claim 1 has been made to solve the above-mentioned technical problem, and an object of the invention is to provide a lubricating machine capable of significantly improving operation quality.

[0007]

According to the first aspect of the present invention, the pair of massagers for performing the massaging operation on the patient is connected to the swing member via the respective arms. . Each swing member is rotatably mounted at a position eccentric with respect to the pair of rotation shafts, and performs a swing operation periodically with rotation of each rotation shaft. Each rotating shaft is individually driven by a pair of driving sources.

Therefore, in the rubbing machine of the present invention, the respective massagers can be operated in an arbitrary phase relationship with each other. As a result, for example, an operation such as an in-phase operation in which a pair of massaging members simultaneously perform a massaging operation, or an operation such as a massaging operation with only one corresponding massaging member by stopping one driving source can be performed. Therefore, various rubbing operations can be performed, a sufficient therapeutic effect can be obtained, and the operation quality can be remarkably improved.

In the rubbing machine according to the second aspect of the present invention, the eccentric position of the pair of swing members with respect to each of the rotation shafts in the rubbing machine according to the first aspect of the invention is detected by eccentric position detecting means. Based on the eccentric position of each rocking member with respect to each rotation axis detected by the eccentric position detecting means, the operational phase difference between the massaging operations of the massagers on the patient is determined at a predetermined set position. The rotation start position of each rotation shaft by each drive source is selected so as to obtain a phase difference. According to the present invention, the same operation and effect as those of the first aspect are realized.

The pair of massagers 10a and 10b are attached to the patient on the outer periphery of the swing members 18 and 19 via arms 20 and 21, respectively. The arm 2 of the swing members 18 and 19
On the side opposite to the mounting position of 0, 21, a pair of rods 22,
23 is pivotally mounted on one end of the rod 22,
The other end of each 23 is swingably attached to the outer periphery of the bearing bands 24 and 25. The bearing bands 24 and 25 have a pair of rotating shafts 26 and 27 having axes in a direction intersecting the axial direction of the rotating shaft 50, and a position eccentric with respect to the axes of the rotating shafts 26 and 27 as a center position. The bearings are mounted via bearings 28 and 29. Therefore, the swing members 18 and 19 are
3 and the rotating shaft 2 via the bearing bands 24 and 25
6, 27.

The rotating shafts 26 and 27 are connected to the frame 14,
The gears 38 and 39 are rotatably supported by bearings 53 and 54 provided on a frame 52 provided between the gears 15 and protrude from the frame 52 and fixed to the ends thereof. The gears 38, 39 are meshed with gears 40, 41 fixed to the rotating shafts of motors 44a, 44b having, for example, a pulse generator. With the above configuration, the rotating shafts 26 and 27 are simultaneously or individually rotated by simultaneously or individually rotating the motors 44a and 44b, which are the driving sources, and the massagers 10a and 10b perform the corresponding rubbing operation.

Note that, in the rubbing machine 1 of this embodiment, the
It is possible to set an arbitrary phase difference between the operations of the motors 44a and 44b. For this purpose, the motors 44a and 44b are used as an example, and a pulse generator or the like is provided as an eccentric position detecting means. The type is such that a predetermined rotation start position of the shaft and a rotation amount from the rotation start position can be detected. Here, the pulse generator provided in the motors 44a and 44b is the bearing band 2
The reason for functioning as the eccentric position detecting means 4 and 25 is as follows. The massagers 10a and 10b perform the massaging operation by hitting the patient when the maximum eccentric position at the rod 22, 23 end as the example of the bearing bands 24, 25 is farthest from the rotating shafts 26, 27. It is. This timing is uniquely determined by the mutual mechanical combination of the rotating shafts 26 and 27, the bearings 28 and 29, and the bearing bands 24 and 25. That is, once these are assembled, the rotational axis 26 of the bearing band 24, 25 at the maximum eccentric position depends on the predetermined circumferential reference position of the rotational shafts 26, 27 depending on which position in the circumferential direction with rotation. , 27, that is, the masses 10a, 1
The position of the approach / separation direction with respect to the patient 0b is determined.
Therefore, the maximum eccentric position of the bearing bands 24 and 25 can be detected by detecting the reference positions of the rotating shafts 26 and 27 by the pulse generator.

In this embodiment, the motors 44a and 44b having such a configuration are used instead of
In addition to having the pulse generators a and 44b, the reference positions of the respective rotating shafts 26 and 27 along a predetermined circumferential direction and the amount of rotation from the reference positions can be detected using an optical sensor or the like. A configuration may be adopted in which a rotary encoder is used as the eccentric position detecting means. By using these configurations, the massagers 10a, 1
An arbitrary phase difference can be set during the operation of 0b.

On the other hand, the driving mechanism 5 includes
A motor 55 for adjusting the interval along a direction parallel to the rotation axis 50 of b is provided. The motor 55 is bidirectionally rotatable.

The rotating shaft 51 is provided with a first screw portion 57 and a second screw portion 58 in which screws which are opposite to each other are formed around a center portion near the boundary. The first screw portion 57 penetrates the vicinity of one end of the adjusting member 30 in which an internal screw meshing with the screw of the first screw portion 57 is formed, and the second screw portion 58 is connected to the second screw portion 58.
And penetrates near one end of the adjustment member 31 in which an internal screw meshing with the screw is formed. Near the other end of each of the adjusting members 30 and 31, the rotating shaft 50 is commonly penetrated, and the adjusting members 30 and 31 are configured to be movable in the circumferential direction and the axial direction with respect to the rotating shaft 50. I have. Further, the adjusting member 3
0, 31 are the rotating shafts 5 with respect to the rocking members 18, 19.
0 are mutually displaceable in the circumferential direction, and the rotation axis 50
Are fixed along the axial direction of.

Therefore, when the motor 55 is rotated in a predetermined direction and the rotating shaft 51 is rotated in one direction, the adjusting member 30
Numerals 31 are supported by the rotating shaft 50 and move in mutually approaching directions. Thereby, the rocking members 18 and 19 and the massager 10
a 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 rotating shaft 51 is rotated in the other direction, the adjusting members 30 and 31
And move in a direction away from each other. Thereby, the rocking members 18 and 19 and the massagers 10a and 10b also move in directions away from each other.
