Yes. Each massage body 21 can be formed into a thick disk shape, a spherical shape, or the like with, for example, resin or hard rubber. In the following, the massage body 21 on the upper end side is referred to as “upper massage body 21a” as necessary, and the massage body 21 on the lower end side is referred to as “lower massage body 21b” as necessary.

The drive unit 18 includes a kneading drive unit 23 that causes the left and right massage members 17 to move toward and away from each other, and a tapping drive unit 24 that causes the left and right massage members 17 to perform alternate tapping operations. As a thing.
The kneading drive unit 23 has an inclined rotating member 25 provided in a state of being embedded in a central bending portion with respect to the support arm 20 of the massage member 17, and an axis oriented in the left-right direction so as to penetrate the inclined rotating member 25. The first rotating shaft 26, the squeeze motor that rotationally drives the first rotating shaft 26, and the support arm 20 is provided at the rear of the central bent portion of the support arm 20. And an anti-sway mechanism 28 that restricts the follow-up. For this steadying mechanism 28, for example, a universal joint such as a ball joint or a universal joint can be employed.

The inclined rotating member 25 is fitted and held rotatably around a mounting boss portion provided concentrically with the first rotating shaft 26 and integrally rotated in an inclined state via a bearing or the like. Therefore, when the first rotating shaft 26 is rotated by driving the kneading motor, the inclined rotating member 25 causes fluctuation-like rotational vibration around the rotational center, and this rotational vibration is massaged via the support arm 20. It will be transmitted to the body 21.

The support arm 20 is held in a state not to rotate with the first rotation shaft 26 by the steadying mechanism 28, but is allowed to operate in a predetermined range along the front-rear direction, the left-right direction, and the up-down direction. Further, between the left and right support arms 20, the tilt direction of the tilt rotation member 25 is maintained at a phase difference of 180 ° around the first rotation shaft 26.
For this reason, the left and right support arms 20 in the stagnation drive unit 23 operate so that the upper massage bodies 21a repeat the mutual approach and separation in the left-right direction, and the lower massage bodies 21b are It will operate to repeat mutual separation and mutual proximity in the direction. When the upper massage bodies 21a are close to each other, the lower massage bodies 21b are separated from each other, and when the upper massage bodies 21a are separated from each other, the lower massage bodies 21b are close to each other. Is generated.

On the other hand, the hitting drive unit 24 has a second rotating shaft 31 provided with its axis centered in the left-right direction so as to be parallel to the first rotating shaft 26 of the inclined rotating member 25 at an upper position, and the second rotating shaft 31.

And a link lever 36 (long crank shaft) provided so as to protrude downward with respect to the housing 35 that rotatably holds the shaft.

The eccentric drive body 34 is configured such that the shaft center of the second rotating shaft 31 and the housing 35 is made inconsistent by mounting an eccentric collar on the inner ring side or the outer ring side of the bearing. The lower end portion of the link lever 36 is connected to the central bent portion of the support arm 20 of the massage member 17, and this connecting portion forms the above-described steadying mechanism 28 (ball joint or the like). ing. That is, the steadying mechanism 28 is provided at the lower end of the link lever 36, and the base end of the support arm 20 is connected via the steadying mechanism 28.

Accordingly, in the tapping drive unit 24, when the tapping motor 32 is driven, the eccentric driving body 34 rotates eccentrically with respect to the axis of the second rotating shaft 31, and the housing 35 moves circumferentially in response thereto. . Accordingly, a vertical pulling operation is transmitted from the housing 35 to the link lever 36 (long crankshaft). For this reason, the left and right support arms 20 oscillate each other's massage body 21 in small increments around the first rotation shaft 26, so that the upper massage body 21a and the lower massage body 21b are relatively opposite in the front-rear direction. Since it moves, this will generate | occur | produce the tapping operation | movement as the massage member 17. FIG.

Note that the swing generated in the left and right support arms 20 occurs alternately because the left and right eccentric drive bodies 34 are provided with a phase difference of 180 °.
That is, when the left support arm 20 moves the upper massage body 21a forward, the right support arm 20 moves the upper massage body 21a backward. Conversely, when the left support arm 20 moves the lower massage body 21b forward, the right support arm 20 moves the lower massage body 21b backward.

As shown in FIG. 4, a motor support base 37 for the tapping motor 32 is provided in the portion that transmits the rotational drive from the tapping motor 32 to the second rotary shaft 31 as a structure incorporating a reduction gear.

Two guide bars 38 whose longitudinal directions are directed in the vertical direction penetrate the motor support 37 in a skewered manner in a parallel state with a predetermined interval therebetween.
These guide bars 38 are installed in the frame with respect to the guide frame 40 that is concave when viewed from the side. The guide frame 40 is configured such that the kneading motor of the kneading drive unit 23 rotates the first rotating shaft 26. A gear head 39 with a built-in speed reducer for transmission is supported (foundation) and is fixed in a state of extending upward.

In other words, the tapping motor 32 is held in a state of being freely movable in the vertical direction (direction approaching and moving away from the kneading motor) along the guide bar 38. Here, the guide bar 38 and the guide frame 40 are tapped. A vertical guide support portion 41 for holding the drive portion 24 so as to be movable up and down is configured.
Since such a vertical guide support portion 41 is provided, the following movement can be realized. That is, when the kneading motor rotates the first rotation shaft 26 and when the tapping motor 32 rotates the second rotation shaft 31, the massage member 17 is in principle provided with the first rotation shaft 26 by the anti-sway mechanism 28. Traveling around is restricted.

However, when the massage member 17 is subjected to a wobbling load by the user, the tapping motors that are connected to each other together with the steadying mechanism 28, the link lever 36, the second rotating shaft 31, the motor support 37, and the like. 32 moves up and down. Therefore, the massage member 17 is a movement in which the massage member 17 is allowed to rotate or swing within a predetermined range around the first rotation shaft 26.

The lower end portion of the massage mechanism 10 having the above configuration is supported by the base member 12 via the swinging pivot support portion 11. The swing pivot 11 has a pivot 42 whose axis is directed in the left-right direction. The massage mechanism 10 swings in the front-rear direction with respect to the base member 12 with the pivot 42 serving as a fulcrum. It is held freely.
In addition, a hinge piece portion that protrudes downward is provided on the gear head 39 of the kneading motor, and a hinge base portion that protrudes forward from the lower end portion of the base member 12 so that the hinge piece portion is clamped from both the left and right sides is provided. It has been. A pivot 42 is provided so as to penetrate the hinge piece and the hinge base in the left-right direction.

The vertical movement mechanism 13 is configured to move the massage mechanism 10 up and down together with the base member 12, and guide rollers are provided on both the left and right sides of the upper and lower portions of the base member 12 with the rotation axis oriented in the horizontal direction. These guide rollers are guided to move up and down along a pair of left and right guide rails incorporated in the backrest portion 3 with the longitudinal direction thereof oriented vertically.

As shown in FIGS. 5 and 6, a screw shaft 48 that can be rotationally driven by an elevating motor 47 is provided between the guide rails, and the base member 12 is screwed to the screw shaft 48. A nut member is built in. Therefore, the screw shaft 48 is rotationally driven by the operation of the elevating motor 47 so that the massage mechanism 10 moves up and down in the backrest portion 3 together with the base member 12.

Accordingly, a user who sits on the seat 2 and presses the back against the backrest 3 can receive a massage over a wide range from the shoulder to the back and the waist.
Next, the “exit / retreat operation mechanism 14” and “swing restriction mechanism 15”, which are characteristic mechanisms provided in the chair type massage machine 1 according to the present invention, will be described with reference to FIG.
The retracting and moving mechanism 14 includes a slider 50 that is movable up and down with respect to the base member 12, a slide mechanism that moves the slider 50 up and down, a transmission arm 52 that connects the slider 50 and the massage mechanism 10, and A rail part 53 provided on the base member 12 and a sliding member 54 provided in a protruding shape from the massage mechanism 10 toward the rail part 53 are provided.

The slider 50 is disposed on the front surface of the base member 12, and is formed as a columnar block that is long in the left-right direction. The vertical movement of the slider 50 with respect to the base member 12 is made up and down between an upper bracket provided so as to project forward from the front upper part of the base member 12 and a lower bracket provided so as to project forward from the lower front part of the base member 12. The slider 50 is penetrated in a skewered manner by a guide bar installed between them, which is possible.

On the other hand, the slide mechanism includes a feed screw shaft that is rotatably installed between the upper bracket and the lower bracket and parallel to the guide bar for the slider 50, and an electric motor that drives and rotates the feed screw shaft. And a motor 64. The feed screw shaft penetrates the slider 50 in the vertical direction, and the slider 50 is provided with a female screw portion that is screwed with the feed screw shaft. The screwed structure between the female screw portion and the feed screw shaft is formed by a square screw, preferably a trapezoidal screw, which is excellent in screw driving force and rattling prevention.

The rail portion 53 is provided on the inner surface of the base member 12 facing the side plate portion 66 projecting forward from the left and right side portions of the base member 12. In the first embodiment, the rail portion 53 is recessed in the side plate portion 66 as a groove. The rail portion 53 is formed to have an upwardly bulging arcuate curve centering on the swinging pivotal support portion 11 in which the base member 12 supports the lower end portion of the massage mechanism 10 in a swingable manner.

The sliding member 54 is formed by a rotatable roller that engages (fits) in a state where it can slide with respect to the rail portion 53 (groove). Therefore, when an external force is applied to the massage mechanism 10 so as to swing around the swing pivot 11, the sliding member 54 moves in an arc along the rail 53, and the massage mechanism 10 swings are stabilized.

The transmission arm 52 is provided with a pair of left and right (two) transmission arms 52 arranged so as to be distributed to both the left and right sides of the massage mechanism 10 and the slider 50, respectively.

It is uniaxially arranged on the axis. Therefore, the pushing / pulling force transmitted to the massage mechanism 10 via the transmission arm 52 is efficiently transmitted to the sliding member 54, and as a result, the sliding member 54 moves smoothly along the rail portion 53. It is easy to produce.

A connecting portion of the transmission arm 52 connected to the slider 50 is provided with a second pivot shaft whose axis is directed in the left-right direction, and a link joint that is swingable about the second pivot shaft is formed. Has been.
In the retracting and moving mechanism 14 having such a configuration, an upward moving force is applied to the slider 50 via a female screw portion screwed with the feed screw shaft by driving and rotating the feed screw shaft by the electric motor 64 of the slide mechanism. Alternatively, it is possible to generate a downward movement force and thereby move the slider 50 upward or downward along the guide bar of the slide mechanism.

When the slider 50 moves upward, as shown in FIG. 5, the transmission arm 52 pushes the sliding member 54 forward along the rail portion 53, so that the massage mechanism 10 moves the swinging pivot portion 11. It swings so as to protrude forward as the center. Therefore, the left and right massage members 17 come forward. FIG. 5 shows a state where the massage mechanism 10 is moved to the upper end position (user's shoulder position) by the vertical movement mechanism 13 and stopped.

When the electric motor 64 of the slide mechanism is driven reversely to the above, as shown in FIG. 6, the slider 50 moves downward via a female screw portion screwed with the feed screw shaft. At this time, the transmission arm 52 pulls back the sliding member 54 along the rail portion 53, so that the massage mechanism 10 returns to the original state (rearward) with the swinging pivot portion 11 as the center. Rocks. Accordingly, the left and right massage members 17 also return to the original state (rear). FIG. 6 shows a state in which the massage mechanism 10 is present at the lower end position (user's waist position) by the vertical movement mechanism 13.

On the other hand, the swing restriction mechanism 15 is a mechanism that is added to the withdrawal / retreat operation mechanism 14 and operates in cooperation (interlocking).

On the other hand, the connection point P2 between the upper end of the semicircular portion L1 and the straight line portion L2, and the connection point P1 between the lower end of the semicircular portion L4 and the straight line portion L5 are pointed (projection point P1, protrusion point P2). ) And connected by a curve with extreme values.

Although the guide rail portion 85 has been described as having a rhombus opening shape in a side view, the line connecting the semicircular portion L1 and the semicircular portion L4 is the long axis of the rhomboid opening, and this long axis is A guide rail portion 85 is formed on the side plate portion 66 so as to face in the front-rear direction. That is, the guide rail portion 85 is disposed radially inward from the rail portion 53 of the retracting and moving mechanism 14 when viewed from the pivot 42 of the swing pivot portion 11, and the long axis of the rhombus opening is disposed on the swing pivot portion 11. It is provided in a slanting direction so as to be along an arc centered at.

The short axis (line substantially perpendicular to the long axis) of the guide rail portion 85 having a rhombus opening has a length that is approximately half of the long axis. The short axis is directed in a direction along a guide bar 38 that supports the hitting motor 32 so as to be movable in the vertical direction (direction approaching and moving away from the kneading motor). The short axis length of the guide rail portion 85 is substantially the same as the vertical movement range of the tapping motor 32.
On the other hand, the sliding member 86 is formed by a rotatable roller that protrudes from the left and right end portions of the second rotating shaft 31 to the left and right sides coaxially with the shaft center, and each of the sliding members 86 is fitted in the concave portion of the rhombus opening. In addition, it is possible to roll on the left and right guide rail portions 85.

In the guide rail portion 85 in which the arrangement and the opening shape are determined as described above, a portion corresponding to the semicircular portion L4 is a first rotation restricting portion 80 as shown in FIG. Further, the semicircular portion L1 is a second rotation restricting portion 81. Each of the first rotation restricting portion 80 and the second rotation restricting portion 81 has an opening width that allows the sliding member 86 to be fitted without rattling.
In addition, the guide rail portion 85 gradually becomes wider in the vertical direction from the first rotation restricting portion 80 toward the intersection point P3, and conversely, as the guide rail portion 85 approaches the second rotation restricting portion 81 from the intersection point P3. The inside of the recess is gradually narrowed in the vertical direction. Accordingly, these regions (between the upper and lower portions of the straight portion L3 and the straight portion L5 and between the upper and lower portions of the straight portion L2 and the straight portion L6) are wider than the sliding member 86 in the vertical direction. In other words, the sliding member 86 is a space in which the sliding member 86 can freely move in the vertical direction, and this space is the rotation allowing portion 82.

Further, as shown in FIG. 7, the guide protrusion 85 provided in the swing restriction mechanism 15 is provided with a first protrusion adjustment part 93 and a second protrusion adjustment part 92.
