Description

[Detailed description of the invention] This invention relates to an improvement of the pine surge machine. When the switch for switching between manual and automatic is set to the automatic side, several positions on the back of the pine surge machine user are automatically adjusted based on a certain program. For example, the neck and the middle part of the back (around the shoulder blades)
A massage wheel is applied to the lower back for a predetermined period of time, and the massage wheel is repeatedly moved up and down a short distance between the massage points and the massage points for a predetermined period of time (this is called pointing). Furthermore, the final massaging wheel can perform rolling pine surge over the entire back by rotating the massaging wheel while moving up and down the entire back from the waist to the neck. It is something.

The present invention will be explained below based on the drawings of one embodiment.

FIG. 1 is a partially cut-away side view of the present invention applied to a chair-type pine surge machine, in which the pine surge is moved up and down along a guide rail 70 that is erected and fixed within the backrest 69 of the chair main body 68. A drive device main body 71 is attached, and a chain 72 is stretched along the back of the guide rail 70.
and a sprocket 74 fixed to one end of an elevating spline drive shaft 73 rotatably supported by the device main body 71, and the drive device main body moves up and down by forward and reverse rotation of the drive shaft. It is becoming possible to do so. Reference numeral 75 denotes a presser roller provided to improve the engagement between the chain 72 and the sprocket 74, to ensure smooth switching during forward and reverse rotation, and to eliminate rattling noise. 76 is a spline drive shaft for massaging, and a pair of massaging wheels 77 are fixed to this shaft in an inclined state. Reference numeral 78 denotes a guide roller for moving the pine surge driving device main body 71 along the guide rail 70. Then, the main body 71 of the pine surge driving device is raised, lowered, and stopped, and the rolling pine surge caused by the rotation of the massaging wheel 77 and the massaging motion of the massaging wheel are performed by forward and reverse rotation as shown in FIGS. 2 to 4. A main shaft 84 fitted to the worm wheel 83 is rotated from a pulley 79 fixed to the output shaft of the motor M through a rotation transmission mechanism of a belt 80, a pulley 81 installed in the drive device, a worm 82, and a worm wheel 83. urge
A gear 85 is fixed to this main shaft 84. This gear 85 is always meshed with a driven gear 86 loosely fitted to one end of the spline drive shaft 73 for elevating and lowering, and a driven gear 87 loosely fitted to one end of the spline drive shaft 76 for kneading. Each side surface of the driven gears 86 and 87 has an engaging pawl 8.
8 and 89 are respectively provided, and the engaging pieces 92 and 93 of the sliding bodies 90 and 91 are respectively fitted to the elevating spline drive shaft 73 and the kneading spline drive shaft 76 so as to be slidable in the axial direction. They are formed to engage and disengage, respectively, thereby forming a clutch mechanism. 94 and 95 are the sliding bodies 90 and 91
These ring-shaped bodies 94 and 95 are loosely fitted to the main body 7 of the pine surge drive device.
The other end of a lever 98 whose center part is rotatably supported by a shaft 97 on a frame 96 of 1 and a shaft support 99, 1, respectively.
00 has been set. And this lever 98 is massaged,
Plunger 101 of solenoid SL for lifting/lowering switching
Due to the suction action, the shaft support 97 also swings as a fulcrum, and the lever 98 moves the annular bodies 90, 91 left and right, thereby moving one of the sliding bodies 90 or 91.
The meshing pieces 92 and 93 formed on the driven gear 8
Either of the engaging pieces 88 or 89 provided in 6 and 87 is connected to one of the engaging pieces 88 and 92

Therefore, when the clutch mechanism formed by the engaging pieces 88 and 92 is engaged, the spline drive shaft 73 for raising and lowering and the driven gear 86 are integrated.
The rotation from the motor is the belt 80, worm 82, worm wheel 83, main shaft 84, gear 8.
5 etc., so the sprocket 74
Both the spline drive shaft 73 for elevating and lowering rotate in either forward or reverse direction at the same time to perform rolling pine surge. When the engagement pieces 88 and 92 are disengaged and the clutch mechanism consisting of the other engagement pieces 89 and 93 is engaged, the rotational force from the gear 85 is transmitted to the spline drive shaft 76 for kneading via the driven gear 87.
As a result, the massage wheel 77 performs massage of the fir tree. At this time, the rotation of the elevating spline drive shaft 73 is stopped.

The pine surge mechanism constructed as described above is controlled by a timer and a relay to operate the engagement/disengagement by a solenoid and the forward/reverse rotation of the motor M based on a certain program. In addition to massaging the area and performing rolling pine surge over short distances,
It is designed to apply a long rolling pine surge to the entire back, and its operation will be explained below based on the sequence circuit diagram shown in FIG.

First, when the manual automatic changeover switch S ₀ is turned on to the automatic side, the current flows from circuit 1 to automatic side contact 2 to stepping relay reset timer T ₀ to circuit 17, and then to stepping relay reset timer T ₀ .
Due to the _{action of}
→The current flows through the electric path 17, and the stepping relay _R0 is reset by the above-mentioned _R.sub.S. The reset stepping relay R ₀ switches to contact 5, and the current in the circuit flows through circuit 1 → automatic side contact 2 → contact 4 → contact → 5 → rising relay R ₁ → electrical circuit 17 and rising relay R _1.
