Extrusion Mechanism (60)

The massage unit 20 is provided with a pushing mechanism 60 for moving the massage unit 20 back and forth, as shown in FIGS. 1 and 2. As the pushing mechanism 60, the structure which consists of the following crank mechanism 61 and the link mechanism 70 can be illustrated.

As shown in FIGS. 5 and 6, the crank mechanism 61 includes a crank shaft 62 provided in front of the rubbing shaft 40, and upper rollers 65 and 65 (see FIG. 6). The crank pins 64 and 64 (refer to FIG. 5) which are rotatably fitted are connected by the crank arms 63 and 63, and are comprised. Since the crank pins 64 and 64 are eccentric with respect to the crank shaft 62, when the crank shaft 62 is rotated, the crank pins 64 and 64 are circumferentially centered on the crank shaft 62. Draw In addition, in the illustrated embodiment, the crankshaft 62, the crank arms 63 and 63, and the crank pins 64 and 64 are constituted by one metal rod, and as shown in Fig. 5, the crank The shafts 62 and 62 are axially supported by the main chassis 21 by bearings 62a and 62a.

As shown in FIG. 3, the support pieces 22a and 22a having the bearings 22b and 22b protrude from the auxiliary chassis 22, and the bearings 22b and 22b are formed in FIGS. As shown in Figs. 4 and 6, the screw shaft 67 for the inclined motion in which the screw groove is cut is supported. The upper end of the inclination motion screw shaft 67 is connected to the pushing motor 69 via a reduction device 68 made of a pulley or a belt (not shown in FIG. 4).

The nut 71 is screwed to the part where the screw of the inclination motion screw shaft 67 is cut off. The nut 71 can be made of resin, and as shown in FIGS. 6 and 7, the link mechanism 70 is connected to the resin nut 71. The link mechanism 70 can be comprised from the link piece 72 and the link piece 78.

In addition, below, the link piece 72 demonstrates the example comprised by the 1st link piece 73 and the 2nd link piece 75 comprised so that mutual expansion | slidability was possible to expand | stretch in a longitudinal direction.

The first link piece 73 is supported by the resin nut 71 so as to be inclined in the front-rear direction, and the slide shaft 74 protrudes from the proximal end side of the first link piece 73.

The 2nd link piece 75 is comprised from a pair of member which clamps the 1st link piece 73 from both sides, and the long hole 76 is formed in the longitudinal direction, respectively. The long hole 76 of the 2nd link piece 75 is slidably fitted in the slide shaft 74 of the 1st link piece 73, respectively.

Moreover, as shown in FIG. 6, the shaft 75a protrudes and is provided in the front-end | tip of the 2nd link piece 75, and the spring 77 is provided between the said slide shaft 74. As shown in FIG. The spring 77 presses the second link piece 75 toward the resin nut 71, and in the no-load state, the spring 77 allows the second link piece 75 to be pulled toward the resin nut 71 as much as possible. It is in a state.

The third link piece 78 is supported by the shaft 75a of the second link piece 75. The third link piece 78 is a link piece that is bent forward from the center, and the tip of the third link piece 78 is fixed to the crankshaft 62.

When the resin nut 71 is located above the inclined screw shaft 67, the third link piece 78 is pulled toward the second link piece 75 side, and the massage unit 20 (main chassis ( 21) is in the pulled out position (see FIG. 1).

In this state, when the inclined motion screw shaft 67 is rotated and the resin nut 71 is moved downward (as shown by the center arrow A in FIG. 7), as shown in FIG. As the movement in the downward direction, the second link piece 75 pulls the engagement portion with the third link piece 78 downward, and the third link piece 78 is centered on the crankshaft 62. To rotate. Since the third link piece 78 and the crankshaft 62 are fixed, the crankshaft 62 rotates together with the third link piece 78.

The crank pins 64 and 64 at both ends of the crankshaft 62 are movable only along the guide rails 14 and 14 by the rollers 65 and 65, and cannot move back and forth. By rotation of the 62, the massage unit 20 inclines with respect to the up-down rotating shaft 24. As shown in FIG. Since the vertical rotation shaft 24 is provided below the massage unit 20, as illustrated in FIG. 2, the sample papers 30 and 30 are pushed forward by the inclined motion of the massage unit 20. (Indicated by arrow B in FIG. 7).

By pushing the sample paper 30, 30 at the shoulder position of the subject, the sample paper 30, 30 reaches to the upper part of the shoulder of the sample. By driving the rubbing motor 41 and the tapping motor 51 in this state, the shoulder upper part of a sample can be massaged effectively.

In addition, by pushing the sample sheets 30 and 30 in the state where the sample sheets 30 and 30 are located below the shoulder position of the sample, i.e., the back and the waist position, the back and the waist of the sample are subjected to acupressure. Is massaged. Moreover, in this state, by rolling up and down the motor 26, the massage unit 20 is lifted and lowered, the rolling massage of the sample paper 30 and 30 pressed strongly by the subject can be performed.

When the inclination motion screw shaft 67 is rotated from the state of FIG. 2, the resin nut 71 will move to the upper side, and contrary to the above, the massage unit 20 will retreat and the sample paper 30 30 is pulled back inside the backrest (see FIG. 1). In the state of pulling back, massage similar to the conventional one can be performed.

By adjusting the rotation of the inclination motion screw shaft 67, that is, the position of the resin nut 71 with respect to the inclination motion screw shaft 67, the amount of protrusion of the massage unit 20 can be adjusted. Moreover, the maximum protrusion amount can also be adjusted by changing the length of the crank arms 63 and 63.

The amount of protrusion of the massage unit 20 can be detected by the amount of protrusion detection means 79. As the protrusion amount detecting means 79, for example, as shown in Fig. 6, a variable resistor 79 that touches the third link piece 78 is provided, and the third link piece ( The change of the resistance value according to the rotation angle of 78) may be measured.

Moreover, since the crankshaft 62 also rotates integrally with the 3rd link piece 78, you may provide the protrusion amount detection means 79 to the crankshaft 62. As shown in FIG.

Other Embodiments of Link Mechanism 70

In the above, the link piece 72 which made the 1st link piece 73 and the 2nd link piece 75 slidable by screw pressurization, and the link mechanism 70 which connected the 3rd link piece 78 were carried out. By this, the crankshaft 62 and the resin nut 71 are connected. The first link piece 73 and the second link piece 75 are slidable from the front of the sample sheets 30 and 30 in a state where the sample sheets 30 and 30 are pushed forward. This is to allow the sample paper 30, 30 (massage unit 20) to retreat slightly when this is applied. As a result, when the sample leans back against the back 12 in the state where the sample sheets 30 and 30 are pushed out, the sample sheets 30 and 30 receive a strong force to the rear and the massage unit 20 retreats. For this reason, it is possible to prevent the sample from feeling pain.

When the above effects are not required, the first link piece 73 and the second link piece 75 are not constituted by separate members, and the third link piece 78 and the resin nut 71 are formed. What is necessary is just to connect with one link piece 72 directly.

Moreover, since the slide amount with respect to the 1st link piece 73 of the 2nd link piece 75 respond | corresponds to the force applied to the sample paper 30, 30, the slide amount of the 2nd link piece 75 is carried out. On the basis of this, the sample sheet 30, 30 may be provided with means 79a for detecting which part of the body of the sample is in contact with. In this case, the slide amount can be detected by pressing the variable resistor 79a or the like on the first link piece 73 so as to contact the second link piece 75 as shown in FIG. 6. .

The sample paper 30 is lowered by lowering the massage unit 20 in a state in which the sample papers 30 and 30 do not come into contact with the sample, that is, the massage unit 20 is located above the back 12. When 30 touches the shoulder of the subject, the sample paper 30, 30 is forced upward.

As a result, the second link piece 75 slides upward while overcoming the pressing force of the spring 77. The sliding amount of the second link piece 75 is detected by the variable resistor 79a, and from the detected value, it can detect that the position is the shoulder of the subject.

Arm Lock Mechanism (80)

The pushing mechanism 60 may be further provided with an arm lock mechanism 80 which also protrudes the sample sheets 30 and 30 in accordance with the pushing out of the massage unit 20.

As shown in FIG. 7, the arm lock mechanism 80 couples the bent portions of the massage arms 32 and 32 and the crankshaft 62 into couplings 81, 81, 82 ( It is connected by arm lock rods 83 and 83 via 82). When the coupling 82 and 82 on the crankshaft 62 side protrude the massage unit 20 to the maximum (see FIG. 2), the rub disk 31 on the upper side of the massage arms 32 and 32 ( 31) in position to push forward as far as possible.

As the crank shaft 62 is rotated and the massage unit 20 is pushed out as described above, the couplings 82 and 82 rotate together with the rotation of the crank shaft 62, so that the arm lock rod 83 ( 83) up. As a result, the arm lock rods 83 and 83 rotate the massage arms 32 and 32 forward, so that the upper and lower rubbing disks 31 and 31a are substantially parallel to the backrest 12. Rub disk 31 protrudes forward with respect to the main chassis 21.

In addition to the pushing of the massage unit 20 by the pushing mechanism 60 described above, by pushing the rubbing disk 31, the rubbing disks 31 and 31 are pushed out to the upper part of the shoulder sufficiently and effectively. Massage can be performed.

In this state, the rubbing shaft 40 and / or the tapping shaft 50 are rotated to perform rubbing and / or tapping massage in a state where the upper rubbing disk 31 protrudes.

When the sample paper 30, 30 is in contact with the subject's back or waist, the above operation can be performed to perform acupressure massage by the upper rubbing disk 31.

When the crankshaft 62 is rotated in the reverse direction and the massage unit 20 is retracted, the coupling 82 and 82 pull the massage rods 83 and 83 downward in the reverse direction. Pull. As a result, the arm lock rods 83 and 83 rotate the massage arms 32 and 32 back so that the upper and lower rubbing disks 31 and 31a return to a state substantially parallel to the backrest 12, Ordinary massage can be performed.

According to the chair-type massager of the present invention described above, when the massage unit itself is moved back and forth by the pushing mechanism, the sample paper is greatly pushed forward. When the sample paper is pushed out of the massage unit while the sample paper is at the rear of the shoulder, the sample paper sufficiently touches the upper part of the shoulder, so that the scrubbing and tapping massage of the upper shoulder with high effect can be performed.

Moreover, acupressure massage can be performed by pushing a massage unit itself with a pushing mechanism in the state which the sample paper contacted to a back, a waist, etc.

In addition, by adjusting the amount of protrusion of the massage unit, the contact strength (weak and weakness) of the sample paper with respect to the sample can be changed, and a highly effective massage can be performed.
