As shown in FIG. 1, the massager 1 is placed on a flat and safe surface such as a table. The user inserts the forearm A (third treatment section) into the insertion recess 3 provided in the case body 2 .

Specifically, the forearm A is inserted into the insertion recess 3 from above while applying force. By pushing the forearm A, the tip end sides of the pair of left and right first massaging members 11a and 11b move outward in the left and right direction.
That is, the left first massaging member 11a rotates about the tip of the first connecting rod member 36a (around the pin member 39), and the right first massaging member 11b rotates about the tip of the first connecting rod member 36b (pin member 39). 39 turns). As a result, the first spring member 48 laid down in the horizontal direction is contracted, so that the left block member 46a arranged in the long groove 45 formed in the support member 42 moves rightward. At the same time, the right block member 46b moves leftward.

On the base end side of the first massaging member 11, the first spring member 48 sandwiched between the left and right block members 46a and 46b contracts due to the compression of the block members 46a and 46b. As a result, the space between the pair of left and right first massaging members 11a and 11b in the left-right direction is widened, and the forearm A can be inserted.
Similarly, when the forearm A is pushed, the distal end sides of the pair of left and right second massaging members 25a and 25b move laterally outward.

That is, the left second massaging member 25a rotates about the tip of the second connecting rod member 49a (around the pin member 52), and the right second massaging member 25b rotates about the tip of the first connecting rod member 49b (pin member 52). 52 turns). As a result, the second spring member 61 laid down in the horizontal direction contracts, so that the left block member 59a arranged in the long groove 58 formed in the support member 55 moves rightward. At the same time, the right block 59b moves leftward.

On the base end side of the second massaging member 25, the second spring member 61 sandwiched between the left and right blocks 59a and 59b contracts due to the compression of the blocks 59a and 59b. As a result, the space between the pair of left and right second massaging members 25a and 25b in the left-right direction is widened, and the forearm A can be inserted.
That is, by pushing the forearm A, the pair of left and right first massaging members 11a and 11b and the pair of left and right second massaging members 25a and 25b are simultaneously spread widely outward in the left and right direction.

A switch section 9 provided on the lower front side of the massager 1 is operated to turn on the power. The drive unit 6 is driven by a command from the control unit 7 . That is, the driving motor 23 of the driving section 6 outputs rotational driving force, which is transmitted to the rotating shaft 21 via the gear case 24 .
When the rotary shaft 21 rotates, the first rotary boss member 15 rotates and slides inside the first annular fitting portion 16 . The first connecting rod member 36 transmits the converted reciprocating rocking motion to the first massaging member 11 .

In other words, the rotational driving force of the rotary shaft 21 is converted by the first rocking motion converter 14 into a reciprocating rocking motion in the front-rear and left-right directions. The first massaging member 11 performs reciprocating rocking motion in the front, rear, left, and right directions via the first connecting rod member 36 as a result of conversion by the first rocking motion converting portion 14 . The first massaging parts 4 swing in the front-rear direction with respect to each other.
At the same time, when the rotating shaft 21 rotates, the second rotating boss member 29 rotates and slides inside the second annular fitting portion 30 . The second connecting rod member 49 transmits the converted reciprocating rocking motion to the second massaging member 25 .

In other words, the rotational driving force of the rotating shaft 21 is converted into a reciprocating rocking motion in the front-rear and left-right directions by the second rocking motion converter 28 . The second massaging member 25 performs reciprocating rocking motion in the front, rear, left, and right directions via the second connecting rod member 49 as a result of conversion by the second rocking motion converting portion 28 .
The second massage section 5 swings in the front-rear direction. That is, the first massaging part 4 and the second massaging part 5 move toward and away from each other in the front-rear direction.

The first rocking motion converter 14 and the second rocking motion converter 28 synchronize the reciprocating rocking motions, and rotate the first massaging part 4 and the second massaging part 5 so that the first massaging part 4 and the second massaging part 5 are repeatedly moved toward and away from each other in the front-rear direction, and the left and right The pair of first massaging members 11 and the pair of right and left second massaging members 25 are converted into rocking motions in which clamping and releasing from the left and right directions are repeated.
As shown in FIG. 9 and the like, the first massaging part 4 sandwiches the forearm A (closer to the elbow) and the second massaging part 5 sandwiches the forearm A (closer to the wrist). The massaging part 4 and the second massaging part 5 are moved in the direction away from each other in the front-rear direction, and perform a stretching operation of pulling the entire forearm A in the front-rear direction.

Specifically, when the first massaging section 4 and the second massaging section 5 approach each other in the front-rear direction and reach a predetermined position, the pair of right and left first massaging members 11 approach each other and move toward the forearm A (side close to the elbow). ) are sandwiched from the left and right, and the pair of left and right second massaging members 25 approach each other and sandwich the forearm A (the side close to the wrist) from the left and right.
Here, the shaft angle detector 35 detects a predetermined rotation angle of the rotating shaft 21 . When the detection signal is transmitted, the controller 7 recognizes that the entire forearm A is sandwiched between the first massaging member 11 and the second massaging member 25 .

The first massaging part 4 and the second massaging part 5 are separated from each other in the front-rear direction by the control unit 7 and maintained in a sandwiched state until they reach a predetermined position (the farthest position). That is, the first massaging part 4 and the second massaging part 5 stretch the entire forearm A in the front-rear direction.
When the first massaging part 4 and the second massaging part 5 are separated from each other in the front-rear direction and reach a predetermined position (the farthest position), the shaft angle detector 35 detects a predetermined rotation angle of the rotating shaft 21 . When the detection signal is transmitted, the controller 7 separates the pair of left and right first massage members 11 and separates the pair of left and right second massage members 25 to release the pinched forearm A.

In summary, for example, when the first massaging section 4 and the second massaging section 5 are closest to each other in the front-rear direction as indicated by arrows in FIG. A pair of left and right second massaging members 25 pinch and massage the forearm A (near the wrist).

The entire forearm A is stretched in the longitudinal direction by separating the first massaging part 4 and the second massaging part 5 in the longitudinal direction while sandwiching the forearm A. - 特許庁
When the first massaging part 4 and the second massaging part 5 reach the farthest position, the pair of left and right first massaging members 11 are separated to open the forearm A (closer to the elbow), and the pair of left and right first massaging members 11 are released. 2 Repeatedly separating the massaging member 25 and releasing the forearm A (the side close to the wrist).
