The kneading operation is performed according to. Further, the tapping treatment element is connected to the support member so as to be angularly displaceable, and the tapping treatment conversion mechanism causes the tapping treatment element to reciprocate with respect to the patient, and the tapping treatment element to be moved. After reaching the terminal position away from the patient, the tapping element resiliently collides with the patient.

Therefore, the operating position such as the distance between the pair of tapping treatment elements and the distance to the patient is determined by the position of the support member to which the massage treatment element is fixed. This allows the pair of massaging treatment elements to be stopped at a position suitable for a predetermined striking operation and performs the striking operation, thereby appropriately setting the mutual width of the pair of massaging treatment elements and the distance to the patient.

8 and the reclining switch 99 are configured as, for example, a changeover switch having three stable positions including a neutral position, and are operated so as to be in a stable position other than the neutral position, so that the width adjustment, the elevating operation, and the reclining operation are desired. Of the degree can be done.

Hereinafter, the operation of the massage machine 1 according to the present embodiment will be described with reference to FIGS.

Alternate beating operation When the beating operation is performed alternately on the patient with the beating treatment elements 10a and 10b, the beating motor 12 is rotated in a predetermined direction. The rotation direction at this time is appropriately set according to the positional relationship between the locking pins 25 and 26 and the projections 33 and 34 of the eccentric collars 31 and 32. When the motor 12 is rotated in the predetermined direction, the rotation is performed by the motor pulley 16 and the toothed belt 1.
7, rotating shaft 2 via relay pulley 18 and worm 19
1a is rotated in a predetermined direction. This allows, for example,
The locking pin 25 moves the projection 33 of the eccentric collar 31 to the rotating shaft 2.
Start rotation around 1a. As a result, the eccentric collar 31 moves the torsion spring 13 against the spring force of the torsion spring 136.
6 begins to be pushed upward in FIG.

By this displacement, the connecting member 41 is displaced upward in FIG. 1, and reaches the upward displaced position. By this operation, the rod 51 is displaced upward in FIG. 1, and the lever 53 shown in FIG. 1 is angularly displaced around the support shaft 130 in the direction of the arrow C <b> 1, so that the beating treatment element 10 a is moved from the patient. Separate.

Since the locking pin 26a is provided at a position shifted by 180 degrees in the circumferential direction from the locking pin 25, the timing of the phase is shifted by 180 degrees with respect to the rotation direction from the operation of the locking pin 25. The projection 34 of the eccentric collar 32
Is rotated around the rotation axis 122 in a predetermined direction.

When the rotation of the rotating shaft 21a further proceeds, the locking pin 25 further rotates the projection 33 of the eccentric collar 31 around the rotating shaft 21a and pushes it further downward in FIG. At the timing when the locking pin 25 is pressing the projection 33, the engagement state between the locking pin 26a and the projection 34 is released. Thus, the eccentric collar 32 released from the engagement with the locking pin 26a is rapidly displaced downward in FIG. 1 by the spring force of the torsion spring 137.

As a result of this displacement, the connecting member 42 is rapidly displaced downward, and the lever 54 is angularly displaced around the support shaft 131. By this operation, the operation of hitting the patient with the tapping treatment element 10b is performed. Here, as shown in FIG. 6, the locking member 48 of the connecting member 43 shown in FIG.
When the sliding hole 125 of the connecting member 42 collides with the surface on the side opposite to the collar 36, a situation in which excessive collision noise is generated is prevented by the buffering action of the buffering member 129.

When the rotation of the rotating shaft 21a further proceeds, the locking pin 25 further rotates the projection 33 of the eccentric collar 31 around the rotating shaft 21, and the eccentric collar 31 reaches the terminal position on the lower side. At this time, the engagement state between the locking pin 25 and the projection 33 is released. Thereby, the eccentric collar 31 is rapidly displaced downward in FIG. 1 by the spring force of the torsion spring 136.

Due to this displacement, the collar 35 and the connecting member 42 are displaced downward in FIG. 1, and the lever 53 is angularly displaced around the support shaft 136 and reaches the downward displaced position shown in FIG. . With this operation, the beating treatment element 10
The operation of hitting the subject in b is performed.

At this timing, the locking pin 26a is engaged with the projection 34 of the eccentric collar 32 again. Hereinafter, the same operation is repeated, and the treatment element 10a,
The alternate beating operation by 10b is performed.

Simultaneous Striking Operation When a striking operation is simultaneously performed on the patient by the striking treatment elements 10a and 10b, the striking motor 12 is rotated in a direction opposite to the predetermined direction. When the motor 12 is rotated in the opposite direction, the rotating shaft 21a rotates in a direction opposite to the rotating direction.
Thereby, as an example, the locking pin 25 and the locking pin 26
b causes the projections 33, 34 of the eccentric collars 31, 32 to start rotating around the rotation axes 21a, 21b. This allows
The eccentric collars 31 and 32 wind and contract the torsion springs 136 and 137 against the spring force of the torsion springs 136 and 137,
It starts to be pushed up in FIG.

When the rotation of the rotating shafts 21a, 21b further proceeds, the locking pins 25, 26 rotate the projections 33, 34 of the eccentric collars 31, 32 in the same direction around the rotating shafts 21a, 21b. Up further. Due to this displacement, the connecting members 41 and 42 are displaced upward in FIG. 1, and the levers 53 and 54 are angularly displaced around the support shafts 130 and 131 in the same direction, thereby covering the tapping treatment elements 10 a and 10 b. Move away from the clinician.

When the rotation of the rotating shafts 21a and 21b further proceeds, the locking pins 25 and 26 further rotate the projections 33 and 34 of the eccentric collars 31 and 32 around the rotating shafts 21a and 21b. 32 reaches the upper end position in FIG. At this time, the engagement states of the locking pins 25 and 26b and the projections 33 and 34 are both released. Thus, the eccentric collars 31 and 32 are rapidly displaced downward in FIG. 1 by the spring force of the torsion springs 136 and 137.

Due to this displacement, the levers 53 and 54 are rapidly angularly displaced around the support shafts 130 and 131, and an operation of simultaneously hitting the patient with the tapping treatment elements 10a and 10b is performed. Hereinafter, the same operation is repeated, and the treatment element 1
Simultaneous tapping operations by 0a and 10b are performed.

Kneading Operation When the kneading operation is performed by the massage machine 1 of the present embodiment, the beating motor 12 is stopped and the kneading motor 13 is rotated. The rotation of the motor 13 rotates the rotation shaft 56 via the gear unit 57. With the rotation of the rotating shaft 56, the bearing bands 64 and 65 perform an eccentric revolving motion around the rotating shaft 56, and are swingably fixed to the housing 66 via the rods 62 and 63.
0 and 61 perform the above-described circumferential motion. This allows
A massage operation is performed by a kneading operation on the patient.

In the massage machine 1 performing such an operation, the tapping treatment elements 10a and 10b are connected to the connecting plates 49 and 50 to which the massage treatment elements 11a and 11b are fixed so as to be angularly displaceable. In the state, the hitting operation is performed.
Therefore, the treatment element 10a, 10
It is also possible to adjust the mutual interval of b, but since the massagers 11a and 11b perform the movement of the elliptical trajectory as shown in FIG. 13, the massagers 11a and 11b are positioned at appropriate positions. By stopping in the posture, the treatment element 1 for beating
A desired hitting operation can be realized by appropriately setting the mutual width of 0a and 10b and the distance to the patient.

That is, in the massage of this embodiment, FIG.
In the state in which the massage treatment elements 11a and 11b are close to each other, the treatment elements 11a and 11b are positioned so that the lower sides of the treatment elements 11a and 11b are closer to each other than the upper side.
And the connection plates 49 and 50 are set. Thereby, the beating treatment elements 10a and 10b perform the beating operation in the closest state. As a result, as shown in FIG. 15, it is possible to effectively massage a relatively narrow treatment site such as the neck of the patient.

Further, in the massage of this embodiment, FIG.
In a state where the massage treatment elements 11a and 11b are separated from each other, the treatment elements 11a and 11b are arranged so that the lower sides of the treatment elements 11a and 11b are separated from the upper sides.
And the connection plates 49 and 50 are set. Thereby, the beating treatment elements 10a and 10b perform the beating operation in the most separated state. Thus, as shown in FIG. 16, it is possible to effectively massage a relatively large treatment site such as the lower back and the back of the patient. Thereby, the massage effect of the massage of the present embodiment can be improved. Furthermore, in the massage machine 1, since the beating operation and the kneading operation can be selectively realized,
Also in this regard, it is possible to realize any of a tapping massage and a massaging massage desired by the patient, and the usability is significantly improved.

The treatment elements 10a and 10b for beating are

In performing the beating operation, the beating treatment elements 10a and 10b are defined between the side of the massage treatment elements 11a and 11b close to and away from the patient. Thereby, when the beating treatment elements 10a and 10b perform the beating massage operation on the patient, the beating treatment elements 10a and 10b perform the beating operation with the pair of massage treatment elements 11a and 11b supporting the patient. Will be done. Therefore, in the massage machine 1, when performing a beating operation,
As compared with the case where the patient is supported by only one side of the massage treatment elements 11a and 11b, the supporting points are provided in a plurality of places, so that a situation that causes pain to the patient is prevented. Thereby, the massage effect can be increased.

Further, in the massage machine 1, the beating rotating shafts 21 a and 21 b are respectively driven to rotate in mutually opposite directions about axes intersecting the kneading rotating shaft 56. Therefore, as described above, the massage treatment elements 11a, 1
Even when the distance between the members 1b and the distance to the patient are adjusted, the respective rotating shafts 21a and 21b for kneading rotate evenly with each other. The force is stabilized, a stable massage operation can be performed on the patient, and the massage effect can be improved.

In the massage machine 1, in the present embodiment, when the beating operation is performed, the beating lever 53,
54 performs a rapid operation by the spring force of the torsion springs 136 and 137, and the rapid operation is performed by the bearings 39 and 40.
Is smoothly tolerated. As a result, a smooth beating operation is realized, and a situation that gives the patient a sense of discomfort is prevented,
Massage effect can be improved.

Further, when a force against the beating treatment elements 10a, 10b acts against the beating treatment elements 10a, 10b, for example, when the subject leans strongly on the massage machine 1, the connecting members 41, 4
In 2, the rods 51, 52 have sliding holes 124, 125.
Enters and contracts. Thereby, the force against the hitting operation is absorbed by the clean members 41 and 42, and the rotation of the hitting rotary shafts 21a and 21b is prevented from being hindered.

Thus, a stable massage operation can be realized even under a situation where a force against the beating operation by the beating treatment elements 10a and 10b is generated, such as the posture of the patient with respect to the massage machine 1, and the massage. The effect can be improved.

In the massage machine 1 of this embodiment, as described above, the cushioning materials 126, 127, 128,
Since the shock absorbers 129, 78, and 79 are provided, the shock absorbing members 128, 129, 78, and 79 realize a shock absorbing action during the beating operation, and the shock absorbing elements 10a and 10b are separated from the patient when the beating treatment elements 10a and 10b are separated from the patient. The members 126 and 127 realize a buffering action. Thereby, a situation in which an excessive collision sound is generated in the beating operation is prevented, and a feeling of discomfort of the patient can be removed and a massage effect can be increased.

Further, in the massage machine 1 of this embodiment, the sound absorbing cover 83 is provided on the patient side of the drive mechanism 5, so that
The noise when the massager performs a massage operation on the patient with the treatment elements 10a, 10b, 11a, and 11b is absorbed by the sound absorbing cover 83, and the noise from the drive mechanism 5 is prevented from leaking to the outside. In addition, the quietness of the massage machine 1 can be 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.

[0085]

As described above, in the massage machine according to the first aspect, the kneading operation conversion mechanism drives the supporting member, and the pair of kneading treatment elements fixed to the supporting member is used for the massager. A kneading operation is performed according to an elliptical locus along the treatment site. Further, the tapping treatment element is connected to the support member so as to be angularly displaceable, and the tapping treatment conversion mechanism causes the tapping treatment element to reciprocate with respect to the patient, and the tapping treatment element to be moved. After reaching the terminal position away from the patient, the tapping element resiliently collides with the patient.

Therefore, the operating position such as the distance between the pair of tapping treatment elements and the distance to the patient is determined by the position of the support member to which the massage treatment element is fixed. This allows the pair of massaging treatment elements to be stopped at a position suitable for a predetermined striking operation and performs the striking operation, thereby appropriately setting the mutual width of the pair of massaging treatment elements and the distance to the patient. As a result, a desired beating operation is realized, and the massage effect can be increased.

Thereby, the pair of eccentric cover members respectively perform eccentric rotational movement. Due to the eccentric rotational movement of the pair of eccentric collar members, the pair of hitting connecting members is angularly displaced around the connecting position with the kneading support member, and the hitting treatment element performs a hitting operation on the patient.

Here, the hitting rotary shaft is set in a direction in which the axis intersects the kneading rotary shaft, and the directions of rotation are set opposite to each other. Therefore, even when the distance between the support member for massage and the distance to the patient fluctuates, since the rotating shafts for massage perform mutually even rotation,
The impact force in the beating operation of the pair of beating treatment elements is stabilized, so that a stable massage operation can be performed on the patient and the massage effect can be improved.

The massage machine according to the fourth aspect is the third aspect.
In performing the hitting operation, the hitting connection member performs a rapid operation, and the rapid operation is smoothly performed by at least one bearing disposed between the support shaft and the hitting connection member. Is acceptable. Accordingly, a smooth beating operation is realized, and a situation that gives a feeling of strangeness to the patient can be prevented, and the massage effect can be improved.

The massage machine according to the fifth aspect is the third aspect.
When a force against a tapping action is applied to the tapping treatment element, the tapping connecting member and the support member contract each other to absorb this force, thereby rotating the tapping rotary shaft. Is prevented.

Thus, a stable massage operation can be realized even under a situation where a force against the tapping operation by the tapping treatment element is generated, such as the posture of the patient with respect to the massage machine, and the massage effect is improved. can do.

The massage machine according to the sixth aspect is the third aspect.
, A first displacement corresponding to a resilient movement of the beating treatment element to a patient at one end of the hitting connection member and / or the support member, and a reverse of the first displacement. A first buffer member is provided at least near the end position of the first displacement of the second displacement in the direction.

[0097] Thus, it is possible to prevent a situation in which an excessive collision sound is generated due to the first displacement of the hitting connection member corresponding to at least the hitting operation, and to eliminate the discomfort of the patient and increase the massage effect. it can.

The massage machine according to the seventh aspect is the third aspect.
In the massaging support member, a first displacement corresponding to a resilient movement of the hitting treatment element of the hitting treatment element to the patient, and a direction opposite to the first displacement in the hitting connecting member. A second buffer member is provided at least near the end position of the second displacement of the second displacement.

Therefore, it is possible to prevent a situation in which an excessive collision sound is generated due to the second displacement of the hitting connection member corresponding to at least the hitting operation, and it is possible to remove a feeling of discomfort of the patient and to increase the massage effect. .

In the massage machine according to the eighth aspect, a tapping treatment element for performing a tapping operation on a patient is formed by covering a central body made of a relatively high-rigidity material with an elastic material. The arm to which the treatment element is connected is also formed of a relatively rigid material.

Accordingly, when performing a beating operation on the patient, attenuation of massage energy which is assumed when the beating treatment element or the arm is formed of a relatively flexible material is suppressed. Thus, the efficiency of the massage operation can be improved.

In the massage machine according to the ninth aspect, when a massage operation is performed on the patient with the treatment element, noise is generated from the drive mechanism provided with the treatment element and driving the treatment element. This noise is absorbed by the sound absorbing cover provided on the patient side of the drive mechanism, so that the noise from the drive mechanism is prevented from leaking out to the outside, and the quietness of the massage machine can be improved. .
