Description

[Detailed description of the invention] 【Technical field】

TECHNICAL FIELD The present invention relates to a pine surgery machine that is equipped with a plurality of types of treatment means that can be experienced with different intensities.

[Background technology]

Excessive pine surge may actually reduce its effectiveness and sometimes even lead to the opposite effect. For this reason, even if the user falls asleep or loses track of time while undergoing pine surgery, to prevent excessive pine surgery, the treatment should be continued once the required time has elapsed. A timer means is provided to prevent excessive pine surge that forcibly terminates the treatment operation. Here, as a treatment method, for example, as shown in Japanese Patent Application Laid-Open No. 60-210260, treatment such as massaging or patting that gives a large stimulus to the human body and increases the strength of the pine surge experienced by the user is used. (hereinafter referred to as "strong treatment") and treatment in which the stimulation such as vibration is small and the strength of the pine surge experienced by the user is small (hereinafter referred to as "weak treatment"). Conventionally, only a single timer means was provided, so the timer means was effective only for treatment means that performed strong treatment, and forcibly ended treatment means that performed weak treatment even after the required time elapsed. In addition, the time required for forced termination of both treatment methods was made the same. For this reason, in the former, the treatment using a treatment method that performs weak treatment may take too long and reduce the pine surge effect, while in the latter, the time until forced termination is short and the treatment method that performs weak treatment may take too long. In some cases, the pine surge effect was not sufficient, or the time required for forced termination was long, resulting in a decrease in the pine surge effect of treatment methods that performed strong treatment.

[Purpose of the invention]

The present invention has been made in view of these points, and its purpose is to improve not only the pine surge effect by a treatment means that performs strong treatment, but also the pine surge effect by a treatment means that performs weak treatment. We are here to provide you with a pine surge machine that can.

[Disclosure of the invention]

Therefore, the present invention includes a plurality of types of treatment means that perform treatments with different perceived strengths, and a timer means for preventing excessive pine surge, which forcibly ends the treatment operation by the treatment means when the required time elapses. The time it takes to forcibly terminate the treatment action set in the timer means is short for treatment means that perform a treatment with a large perceived strength, and short for a treatment method that performs a treatment with a low perceived strength. The treatment method used is characterized by its length, and the time until forced termination is varied depending on the strength experienced (treatment intensity). The present invention will be described in detail below based on illustrated embodiments. This pine surgery machine includes a treatment means A built into the backrest of a chair, and a treatment means B built into a footrest 60 placed at the tip of the seat of the chair.

Further, the footrest 60 arranged at the tip of the seat 82 of the chair is rotatably attached to the lower frame 81 via a link (not shown), and is connected to the floor below the seat 82. When pulled forward from the almost vertical storage state, it becomes approximately the same height as the seat portion 82. The treatment means A incorporated into the backrest 84 is
As shown in FIG.
A reduction gear block 19 is provided at the other end, and the rollers 18 and the pinion 17 which are rotationally driven are provided protruding from both blocks 20 and 19. Between the two blocks 20 and 19, the main shaft 1 and the screw shaft 14 and an auxiliary shaft 13 are installed. And both blocks 2
Auxiliary shaft 1 supported at both ends by 0,19
3, the main shaft 1 is connected via a pair of rotating plates 15, 15 which are rotatable with respect to the auxiliary shaft 13.
A rotating shaft 1 parallel to the screw shaft 14 and the auxiliary shaft 13
2 is attached so that the rotating shaft 12 can freely rotate around the auxiliary shaft 13. The rotating shaft 12, which is supported at both ends by a pair of rotating plates 15 and 15 and is rotatable relative to the rotating plate 15, is centered around a pair of crankshafts 12a and 12b whose eccentric directions are opposite to each other. The non-eccentric parts 12d and 12e at both ends are supported by the rotary plate 15. The motor housed in the motor block 20 not only rotates the main shaft 1, screw shaft 14, rotating shaft 12, and pinion 17, but also rotates the rotating shaft 12 around the auxiliary shaft 13. That is, a driven shaft 31 disposed on the outer surface of the reducer block 19 is connected to a pulley 28 attached to the output shaft of the motor protruding below the motor block 20 via a belt 29 and a pulley 30. , and the driven shaft 31 and the reduction mechanism section in the reduction gear block 19,
Clutch 33, pulleys 34, 36 and belt 3
It is connected with 5. The reduction mechanism section (not shown) in the reduction gear block 19 is composed of a reduction section and a plurality of clutch sections, and when the clutch 33 is connected, the main shaft 1, screw shaft 14, or pinion 17 selectively transmits motor output to.
Also, the driven shaft 31 includes a clutch 32 and a pulley 3.
7. A worm wheel 41 mounted on the auxiliary shaft 13 is connected via a belt 38, a pulley 39, and a worm 40.
The gear 42 integrated with the non-eccentric portion 12d of the rotating shaft 12
It meshes with a gear 43 fixed to. When the clutch 32 is connected, the motor output is transmitted to the rotary shaft 12 through the above-mentioned members, and the rotary shaft 12 rotates about the shaft. Furthermore, a pulley 2 is provided on the outer surface of the motor block 20.
1, 23, a belt 22, and a clutch 24, a feed screw 25 is connected to the motor, and a feed nut 26 is screwed onto the feed screw 25.
and one of the pair of rotating plates 15, 15 are connected by a link 16. Feed screw 25
When rotated by the motor output, the feed nut 26, which moves in the axial direction of the feed screw 25, moves the rotating plate 15 via the link 16, and as a result,
The rotating shaft 12 supported by the rotating plate 15 rotates around the auxiliary shaft axis 13. Now, a pair of inner rings 2, 2 are attached to the main shaft 1 at intervals. Both inner rings 2, 2 are the main shaft 1
They are eccentric by the same amount in the same direction and inclined in opposite directions to each other, and are designed to rotate together with the main shaft 1 by engaging with the protrusion 11 formed on the main shaft 1. It is designed to be able to slide freely in the axial direction, and outer rings 3 and 3 are provided on the outer peripheral surface, respectively.
is attached so that it can rotate freely. Also, each inner ring 2, 2
One end of each connecting arm 6, 6 is freely rotatably connected to the outer circumferential surface of the non-eccentric portion. This connecting arm 6, which is adapted to slide in the axial direction of the main shaft 1 together with the inner ring 2, is threadedly engaged with the threaded shaft 14. In addition, each connecting arm 6,
6 are screwed into the parts of the screw shaft 14 whose screw directions are opposite, so that the screw shaft 1
4, both connecting arms 6, 6 move the pair of inner rings 2, 2 toward or away from each other. The middle portions of the arms 4, 4 are fixed to the outer rings 3, 3, respectively. A roller-shaped treatment element 5 that can freely rotate with respect to the arm 4 is attached to the bent portion at the tip of each arm 4, and the other end of one arm 4 is connected to a connecting link 8 and a sphere 70.
The other end of the other arm 4 is connected to the crankshaft 12b of the rotation shaft 12 via the connecting link 8 and the sphere 70. The sphere 70 here is the rotation axis 12
The connecting link 8 and the crankshafts 12a, 12
The engagement with b is achieved by enclosing the sphere 70 with one end of the connecting link 8. For this reason, the connecting link 8 is 3
Dimensional rotation is possible, and since the connecting portion between the other end of the connecting link 8 and the arm 4 is also formed as a ball joint (not shown), three-dimensional rotation is also possible. It's summery. Further, the non-eccentric portion 12c at the center of the rotating shaft 12 and the auxiliary shaft 13 are connected to each other by a connecting plate 9 which is freely rotatable. Next, the outline of the operation of the treatment means A will be explained. When the main shaft 1 is rotated by a motor, the inner ring 2 that rotates together with the main shaft 1 is eccentric and inclined with respect to the main shaft 1. 3 to arm 4
Since the movement of the arm 4 is restricted by the connecting link 8, the treatment element 5 attached through the arm 4 moves in a three-dimensional trajectory as the main shaft 1 rotates. That is, the vertical direction and main axis 1
A movement is performed to change the position in the axial direction of the main shaft 1 and in the direction of protrusion from the main shaft 1. The pair of treatment elements 5, 5, which perform such movements symmetrically, apply a strong pine surge of so-called "kneading" to the back of the user. When the rotary shaft 12 is rotated around the auxiliary shaft 13 via the link 16 and the rotary plate 15 by rotating the feed screw 25 by the motor, the arm 4 and the outer ring 3 are rotated into the inner ring. 2, and the treatment element 5 changes the amount of protrusion toward the front where the user's back is located, so when rotating the main shaft 1 to obtain the pine surge, the same "nerimomi" is applied. Even with pine surge, you can get pine surge with different strengths. When the rotating shaft 12 is rotated instead of the main shaft 1, since each arm 4 is connected to the crankshafts 12a and 12b, which are eccentric parts of the rotating shaft 12, via the connecting link 8, in this case, The connecting link 8, which is moved as the crankshafts 12a and 12b eccentrically rotate, moves the arm 4. At this time, the arm 4 rotates around the stationary inner ring 2 together with the outer ring 3. Therefore, the treatment element 5 provided at the tip of the arm 4 is
Although it depends on the position of the inner ring 2, when viewed from the front, it will be a linear reciprocating movement in an approximately vertical direction, resulting in a tapping and pine surge. Furthermore, since the eccentric directions of both cranks 12a and 12b of the rotating shaft 12, which is the eccentric member 7, are 180 degrees opposite to each other, the tapping and pine surge operation is performed alternately on both the treatment elements 5, 5. In addition, during the pine surge operation of the above-mentioned "kneading", by detecting the eccentric direction that changes with the rotation of the rotating shaft 12, both crankshafts 1
The position of the pair of arms 4 and treatment elements 5 that swing around the center of the inner rings 2 and 2, respectively, with the eccentric direction of the rings 2a and 12b being in a specific direction, that is, with the rotation of the rotating shaft 12. are set to be equal to each other so that there is no "discrepancy". When the pinion 17 is rotated by the motor, the engagement between the rack 91 and the pinion 17 causes the treatment means A to move the backrest 84 of the chair, which is a treatment table, up and down along the rail 90.
Therefore, the position of the treatment element 5 can be changed up and down. Further, at this time, since the roller-shaped treatment element 5 rolls along the back surface of the human body, a rolling pine surge in which the treatment element 5 rubs the back surface of the human body can be obtained. When the screw shaft 14 is further rotated, the treatment element 5
moves in the axial direction of the main shaft 1, and the pair of treatment elements 5, 5
In order to change the spacing between the two, the axial position of the treatment element 5 can be changed depending on whether the area to be treated is the shoulder or the neck. When the tapping motion by rotating the rotating shaft 12 around the axis is executed in parallel with the movement motion by rotating the pinion 17, the "tapping rolling motion" is performed in which the treatment element 5 performs the tapping motion while moving up and down. It is possible to obtain a "pine surge", that is, a "pine surge" in which the part to which the tapping motion is applied sequentially changes up and down. Next, a footrest 60 on which the treatment means B is provided.
I will explain about it. This is shown in Figure 4,

A vibrating pine surge is applied to the user's legs placed on top of the . As is clear from the above, this pine surge machine is equipped with treatment means A that performs strong treatments such as "kneading" and "tapping" and treatment means B that performs weak treatment such as vibration pine surge. However, both treatment means A and B perform operations based on input from an operating device 50 that is detachably attached to the armrest of the chair. This operating device 50 is connected to the main body control unit installed in the chair and the power supply circuit D.
As shown in FIG. 5, a mode switch SW ₂ for setting the operation mode of the treatment means A;
It is a push-on type for selecting various pine surges obtained by treatment method A such as "rolling", "sideburns", "kneading", "tapping rolling", and "tatting". Switches SW ₃₀ to _{SW 33} serving as molds, switches SW ₄ and SW ₅ for changing the position of the treatment element 5 from upper to lower,
Switches SW ₆ and SW ₇ are used to change the width (pitch) of both treatment elements 5, 5, and the rotation of the rotary plate 15 adjusts the angle of the arm 4 around the main axis 1. In addition to switches SW ₈ and SW ₉ for adjusting the amount of protrusion from the treatment means B, a switch SW ₄₁ is provided for the treatment means B, and light emitting elements L ₂ , L ₃₀ to _{L 33} , L are provided for displaying operation. ₄₁ , the light emitting element drive circuit A shown in FIG. 2, and the switch
A signal forming circuit B1 that creates pulse code signals according to the operation of _each of the above switches SW ₂ to _{SW 9} except SW ₄₁ and sends them to the main body control section, and a signal discrimination circuit B that discriminates the sent pulse code signals. It is equipped with a control circuit CPU ₁ consisting of ₂ and 1. The main body control section includes a signal discrimination circuit C ₂ that discriminates signals sent from the control circuit CPU ₁ of the operating device 50.
A control circuit CPU ₂ includes a signal forming circuit C ₃ that sends signals to the controller 50, a timer circuit C ₄ , an operation instruction circuit C _1, etc., and a motor that drives the motor M ₁ according to the output of the operation instruction circuit C ₁ . The drive circuit includes a solenoid drive circuit H for controlling each clutch 24, 32, 33, . . . and a vertical position detection circuit _S4 for detecting the vertical position of the main shaft 1, and a Width position detection circuit S ₃ for detecting the interval, protrusion amount detection circuit S ₁ for detecting the amount of protrusion of the treatment element 5 as the main shaft 1 rotates, arm protrusion amount detection circuit S ₂ , both treatment elements 5, 5. It is constituted by a discrepancy detection circuit _S5 , etc. for detecting the discrepancy. The switch SW ₄₁ and the light emitting element L ₄₁ for the treatment means B provided on the operating device 50 are connected to the control circuit E for the treatment means B, unlike other switches and light emitting elements. This control circuit E includes a light emitting element drive circuit E ₃ for the light emitting element L ₄₁ and a switch.
It consists of a signal discrimination formation circuit E ₂ to which SW ₄₁ is connected, a motor drive circuit E ₄ for motor M ₂ , and a timer circuit E ₁ , as shown in FIG.
L screwed to frame 85 of backrest 84
It is fixed to a letter-shaped base 95. A power cord 96 is connected to this control circuit E, and three connectors CN ₁
~CN ₃ is provided, and the power supply circuit D and control circuit CPU ₂ are connected to the connector CN ₁ , and the connector
An operating device 50 is connected to CN ₂ , and a connector
The motor _M2 of the treatment means B of the footrest 60 is connected to _CN3 . In other words, the connection between the operating device 50 and the control circuit CPU ₂ is also via the board on which the control circuit E is installed, and by concentrating the connections on the control circuit E in this way, the control circuit E functions as a connecting block for wiring, making wiring work easier. However, in this pine surge machine, the operating device 50
Therefore, it is possible to give operation instructions to treatment means A, which performs strong treatment, as well as operation instructions to treatment means B, which performs weak treatment.
It is also possible to operate only one of the treatment means A, B, and furthermore, the operating state of both treatment means A, B can be confirmed by the operating device 50 using the light emitting element. The timer circuit C ₄ provided in the control circuit CPU ₂ for the treatment means A and the timer circuit E ₁ provided in the control circuit E for the treatment means B are as follows:
The time required for the treatment operation of treatment means A and treatment means B to be forcibly terminated is set. That is, in the timer circuit _C4 , the mode switch _SW2 is switched to the treatment means A.
The count-up starts from the point when the
Even if SW ₂ is still in a position to cause the treatment means A to perform the operation, it stops the operation of the treatment means A. In the timer circuit _E1 , a count-up is started from the time when the switch SW ₄₁ is operated and the treatment means B starts operating, and when a predetermined time period has elapsed, the treatment means B is stopped. However, the time limit set in the timer circuit E 1 for treatment means B, which performs weak treatment, is longer than the time limit set in timer circuit C ₄ , for treatment means _A , which performs strong treatment. Because of the length, even if both treatment means A and B are activated at the same time, treatment means A, which provides stronger treatment, will stop sooner. If a strong treatment is performed for too long, the pine surge effect will actually decrease, and if a weak treatment is performed for a certain amount of time, the effect will not be seen. C ₄ and E ₁ are provided so that each time limit can be set individually, so that the continuous operation time of treatment means A for strong treatment and the continuous operation time of treatment means B for weak treatment. It is possible to set both the time and the time to an optimal value.

【Effect of the invention】

As described above, in the present invention, a treatment method that performs strong treatment is limited to a short time until forced termination, and a treatment method that performs weak treatment is limited to a long time until forced termination. Therefore, for treatment methods that perform strong treatment as well as treatment methods that perform weak treatment, the time is too short and the sufficient effect cannot be obtained, or the time is too long and the pine surge effect decreases. This allows you to get a safe and comfortable pine surge without having to do anything.
