EXAMPLES The present invention will be described in detail below with reference to the illustrated examples.
Although it is incorporated in the backrest or bed of the chair, in the illustrated example, as shown in FIG. 9, it is shown that it is incorporated in the backrest 12 of the chair 1 which can be freely reclined. This chair 1 is a lower frame 1 framed by pipes
0 is provided with a seat portion 11 and an armrest 13 and the lower portion of the frame of the backrest 12 is pivotally attached to the lower frame 10, and the gas spring 1 is provided between the lower end of the backrest 12 and the lower frame 10.
5 is attached so that the backrest 12 can be reclined by the expansion and contraction of the gas spring 15. At the tip of the seat portion 11, an ottoman 16 which is a footrest with a built-in vibration massage mechanism is rotatably attached. Has been.

As shown in FIGS. 11 to 13, the massage mechanism M includes a motor block 3 and a gear block 4, a strength adjustment block 5, a power switching block 6, a width moving block 7, a beating drive block 8, and both ends. The chair 1 is composed of a main shaft 20, a connecting shaft 95, and the like that are installed between the motor block 3 and the gear block 4 located at both ends, and the chair 1
Rolling inside the rails in the backrest 12 of the roller 9
4, 96, and a pinion 93 that meshes with a rack attached to the rail and moves the massage mechanism M along the rail by its rotation.

The motor block 3 is provided with a motor 30 whose rotation speed is variable. The rotation output of this motor 30 is a pulley and a belt, and a strength adjustment block 5 containing an electromagnetic clutch and a pair of electromagnetic waves. It is sent to a power switching block 6 having a built-in clutch, and is sent from the power switching block 6 to a gear block 4 and a knocking drive block 8.

The power sent to the gear block 4 is
It is selectively sent to three of the worm shaft 41, the worm shaft 42 and the width drive block 7 by the switching means 43 composed of a planetary mechanism and the electromagnetic clutch. The worm shaft 41 engages with the worm hole 91 connected to the pinion 93 to move the massage mechanism M up and down.
The worm shaft 42 rotates the main shaft 20 via the worm hole 44 and the pair of elliptical gears 45 and 46, and the width drive block 7 rotates the feed screw 70, so that the pair of treatment elements 2 and 2 can be rotated as described later. Change the interval.

The beating drive block 8 has a drive shaft 80 and
The drive shaft 80 includes a crank shaft 82 which is rotatable around the drive shaft 80 and is rotationally driven about its own shaft. Power transmitted from the power switching block 6 is generated around the crank shaft 82. Rotate to. Then, one end of a lever 85 connecting the drive shaft 80 and the crankshaft 82 has a strength adjustment block 5 that is composed of a feed screw and a feed nut that moves axially by the rotation of the feed screw.
Is connected to the feed nut at via a link,
When the strength adjustment block operates, the crank shaft 82 rotates around the drive shaft 80.

At the center of the main shaft 20, a pair of inner rings 22, 2 are provided.
2 is slidably mounted so as to rotate integrally with the main shaft 20. The two inner rings 22, 22 are eccentric to the main shaft 20 in the same direction by the same amount and are inclined in opposite directions, and outer rings 24, 24 are respectively mounted on the outer circumferences thereof so as to freely rotate. There is. As is apparent from FIG. 12, the middles of the arms 25, 25 are fixed to the outer rings 24, 24, respectively, and the bent portions at the tips of the arms 25 are freely rotatable with respect to the arms 25. The respective roller-shaped massaging elements 2 are attached. The other end of each arm 25 is connected to the crank shaft 82 via a connecting link 27. The connecting link 27 is a ball joint 26, 28 that allows the arm 25 and the crank shaft 82 to be freely three-dimensionally rotated.
In particular, the ball joint 28 connected to the crank shaft 82 is slidable in the axial direction with respect to the crank shaft 82. In addition, each inner ring 2
2 is connected to the feed screw 70 in the width moving block 7 by a connecting arm 75. When the feed screw 70 rotates, the pair of connecting arms 75 screwed to the portions of the feed screw 70 having the opposite screw directions move the treatment elements 2 and 2 closer to or away from each other. , Change its spacing.

However, in the massage mechanism M, when the main shaft 20 is rotated by the motor 30, the main shaft 20 is rotated.
Since the inner ring 22 that rotates together with the main ring 20 is eccentric and inclined, the treatment element 2 attached via the arm 25 to the outer ring 24 that is rotatably attached to the inner ring 22 is Since the movement of the arm 25 is restricted by the connecting link 27, a movement that draws a three-dimensional trajectory along with the rotation of the spindle 20, that is, the vertical direction, the axial direction of the spindle 20, and the spindle 20. Perform a movement that changes the position in the direction of protrusion from. The pair of massaging elements 2 and 2 which perform such a movement symmetrically give a so-called "nervation" massage to the back surface of the user.
Depending on the rotation direction of the main shaft 20, it is possible to obtain different massages of “burning up” and “burning down”.

When the strength adjusting block 5 is actuated by the motor 30 and the crankshaft 82 is rotated around the drive shaft 80 as described above, the arm 25 is rotated around the inner ring 22 accordingly. The massager 2 changes the amount of protrusion in the front direction in which the back surface of the user is positioned, and can adjust between a strong massage and a weak massage.

When the crankshaft 82 of the beating drive block 8 is rotated about that axis, the crankshaft 8
2, the connection link 27 that is moved as the eccentric portion rotates,
27 moves the arm 25, and the movement of the arm 25 at this time moves around the inner ring 22 that has stopped to the outer ring 24.
Since the treatment element 2 at the tip of the arm 25 has a linear reciprocating motion in a substantially vertical direction when viewed from the front, the massaging element 2 at the tip of the arm 25 performs a tapping massage, because the massaging element 2 rotates together with the massaging element 2.

Further, the width moving block 7 is driven by the motor 30.
When the is driven, the pair of treatment elements 2, 2 move in the axial direction of the main shaft 20 to change the spacing, so that the spacing can be set according to the treatment site, and when the pinion 93 is rotated. As described above, the massage mechanism M moves up and down along the backrest 12 of the chair.
Therefore, the position of the treatment element 2 can be changed up and down. Further, at the time of this movement, it is possible to obtain a rolling massage in which the treatment element 2 moves while rubbing the back surface of the human body. Further, if the knocking drive block 8 is simultaneously operated, a rolling massage with a knocking motion can be obtained. .

FIG. 8 shows a control circuit C for controlling the operation of this massage mechanism. In the figure, A is as shown in FIG.
An operating device including a switch group for instructing various operations, a control circuit for sending out the operation of these switch groups as a digital signal, and a display lamp. The control circuit C to which the operating device A is connected is a motor drive circuit. The motor 30 is connected via the MD, the solenoid constituting the electromagnetic clutch or the like is connected via the solenoid drive circuit SD, and further various sensors for detecting the operating position information of the treatment element 2 are connected. There is.

The control circuit C turns on / off the motor 30 and switches the rotation direction in accordance with the content of the instruction given from the operating device A, and operates the solenoids appropriately to cause the treatment element 2 to perform the various treatment operations described above. Or perform treatment 2
In order to control this operation, the “rubbing force” adjustment switch SW provided on the operation device A is moved.
Is set to “constant”, “variable”, or “invariant”, the control circuit C differs in the operation of adjusting the amount of protrusion of the treatment element 2 toward the human body. Control.

That is, when it is set to "variable", as shown in FIG. 1, the pressure b detected by the pressure detection sensor provided in the treatment element 2 is the current buff force for a predetermined time T. When it deviates from the setting, the protrusion amount c of the treatment element 2 is changed so that the detected force b matches the force b.
In other words, for the user, when he / she desires to perform treatment with a stronger bending force than the current bending force, the body is pressed against the treatment element 2 and the pressure detected by the pressure detection sensor provided in the treatment element 2 is detected. If a is set to be high, the protrusion amount c of the treatment element 2 becomes large at the time when the predetermined time T elapses, and the treatment is performed with the desired strength of the rubbing force. When the user wants to perform treatment with a weaker kneading force than the kneading force, the body can be separated from the treatment element 2 so that the pressure a detected by the pressure detection sensor provided in the treatment element 2 becomes low.
When the predetermined time T elapses, the protrusion amount c of the treatment element 2 is reduced and the treatment is performed with a desired weakness of the kneading force. If the pressure change time t detected by the pressure detection sensor is shorter than the predetermined time T, the above adjustment is not performed.

When the "rubbing force" adjusting switch SW is set to "constant", as shown in FIG. 2, when the pressure a detected by the pressure detecting sensor rises for a predetermined time T, the control circuit C Is adjusted so that the protruding amount of the treatment element 2 is reduced so that the buffing force B maintains a constant value, and when the pressure i detected by the pressure detection sensor decreases for a predetermined time T, the control circuit C causes the treatment element 2 to move. Increase the amount of protrusion and adjust so that the rubbing force b maintains a constant value.

When the "rubbing force" adjusting switch SW is set to "invariant", as shown in FIG. 3, the protrusion of the treatment element 2 is caused irrespective of the change in the pressure a detected by the pressure detecting sensor. Keep the amount constant. FIG. 4 is a flowchart of these operation controls. Although the strength of the massage force is adjusted by changing the protrusion amount of the treatment element 2 in the above-described embodiment, the strength may be adjusted by changing the operation speed of the treatment element 2. The strength adjustment may be performed by changing both the operation speed and the operation speed. Further, it is preferable that the constant value of the rubbing force to be maintained when it is “constant” can be adjusted according to the preference of the user.

FIG. 5 shows another embodiment. This is to change gradually the projection amount c in order to follow the pressure force b detected by the pressure detection sensor when the “rubbing force” adjustment switch SW is set to “variable”. It was something that I tried to do. However, when the difference between the pressure b and the force detected by the pressure detection sensor exceeds a certain value (4 in the illustrated example), as shown in FIG. Preferably.

Further, the speed of change of strength may not be changed according to the relative difference, but the speed of change of strength may be changed according to the absolute value of the pressure a detected by the pressure detection sensor. May change the amount of change of the rubbing force depending on the absolute value of the pressure a detected by the pressure detection sensor, the difference between the pressure i and the rubbing force, or a value such as a rate of change. In other words, instead of letting the detected pressure (i) follow the rubbing force completely, change the rubbing force a little in the direction in which the difference between the two becomes smaller, or change the rubbing force to the point where it exceeds the detected pressure (i). You may. When performing control with such weighting, fine adjustment becomes easy.

The operating device A is also provided with manual strength adjustment switches S1 and S2, and a predetermined period T1 after the strength adjustment is performed by the strength adjustment switches S1 and S2 is as shown in FIG. In addition, even if the pressure a detected by the pressure detection sensor changes, it is necessary to prevent the protrusion amount c from following this, so that adjustment contrary to the intention of operating the strength adjustment switches S1 and S2 is performed. It is preferable in terms of preventing

The pressure detecting sensor does not have to be provided directly on the treatment element 2, and for example, as shown in FIG.
A strain sensor S that detects the reaction force applied to the arm 25 or the crankshaft 82 as a stress applied to the link connecting the strength adjustment block 5 may be used.
In addition, since the operation of the operating device A is often performed by feeling, when the "rubbing force" adjustment switch SW or the like is operated, a newly set state is notified by voice notification or the rubbing force is increased. Providing a voice notifying means for notifying the transition by voice when performing the operation enables accurate operation and prevents the user from being confused by sudden changes in the rubbing force.

[0025]

As described above, according to the first feature of the present invention, the strength can be changed depending on whether or not the body is pressed against the treatment element, and the strength can be manually changed. It can be strengthened or weakened without any change. According to the second characteristic, the strength is always constant regardless of the pressing force to the body against the massager. According to the third feature, it is possible to select the above-mentioned two types of operations, and the usability is improved.
