Description

[Detailed Description of the Invention] [Technical Field] The present invention includes a pair of wheels that are freely rotatable, and by moving the wheels, an action is performed to stretch the back muscles where the two wheels come into contact. This invention relates to a pine surge device that performs pine surge.

[Background Art] When performing Tasasuri Matusage along the back muscles to lengthen the back muscles, it is structurally simple to roll a reversible wheel like a roller along the back muscles. However, by simply moving the wheel in a rolling motion, it was possible to obtain only a single strength of sarasumatsusurge, which was determined by the contact pressure between the wheel and the human body, and it was not possible to vary the intensity. .

[Object of the Invention] The present invention has been made in view of the above points, and its object is to provide a pine surge device that can adjust the intensity of pine surge.

[Disclosure of the Invention] The present invention provides a main shaft in which a pair of ring bodies are both eccentric and freely rotatable and are mounted at a predetermined interval in the axial direction, and a main shaft that is perpendicular to the axial direction. a rotational drive means for rotating the spindle at least half a rotation around the axis; a sensor for detecting the rotational position of the spindle; and a sensor for locking the movement of the spindle around the axis based on the output from the sensor. It is characterized in that it is equipped with a locking means that allows the wheel to move along with the main shaft to move along the back muscles, and also to eccentrically move the wheel. By rotating the main shaft at least half a turn, the amount of protrusion of the part of the wheel that makes contact with the body from the main shaft can be changed, thereby making it possible to adjust the strength. be. Here, the main shaft may be made to be able to rotate continuously instead of being able to simply rotate for half a rotation. In this case, since the amount of protrusion of the ring body changes continuously and periodically, an acupressure-like pine surge can also be obtained.

The present invention will be described in detail below based on the illustrated embodiment. FIG. 1 shows the appearance of one embodiment, and FIG. 2 shows the state of use. A leg portion 41 is provided with a cushion portion 42 on the upper surface of both ends, a side frame 43 on both sides, and a cover sheet 6 on the upper surface.
As shown in the figure, the legs 41, the cover sheet 6, and the side frames 43 are attached to a framework in which the opposite ends of a pair of frames 4, 4 made of pipes are connected by a horizontal beam 44 and a bottom plate 45, respectively. It is installed. A rack 8 is attached to each of the frames 4, 4, and an opening is fixed to opposing rails 7, 7, and the cover sheet 6, which has a mandrel 47 passed through its both ends, has a hook hole. 48 to lock a hook protrusion 46 protruding from the rail 7;
A mandrel 47 is placed inside the horizontal bar 44 provided with a slit 49.
It is attached by passing it through. side frame 4
3 is a core material 50 with foamed urethane resin 51 and cloth 52 wrapped around the outer surface thereof, and is fixed to the frame 4 with screws.

A mechanism section including a wheel body 2 for performing pine surge is installed between the pair of rails 7, 7. This mechanical section has a motor M and is self-propelled along a rail 7. A motor block 9 is disposed at one end, a gearbox 10 is disposed at the other end, and a pair of transport bodies 2 are disposed between the two. , 2 are connected to each other by a main shaft 1 which is mounted in the center at intervals. The main shaft 1 has cylindrical bodies 16, 16 freely rotatably attached to both ends thereof, and guide rollers 17 provided on each cylindrical body 16 run within the rails 7. Further, as shown in FIG. 5, guide rollers 17 are attached to the gearbox 10 and the motor block 9 via shafts 53, and the mechanical part is constructed between a pair of rails 7, 7 with a total of four guide rollers 17. This is what is being done. Further, a shaft 5 parallel to the main shaft 1 is provided on the upper surface of the gearbox 10 and the upper surface of the motor block 9, respectively.
Two side rollers 5 supported by rollers 9 are provided. These four side rollers 5 located on both sides of the pair of wheels 2 are connected to a shaft 59.
It is said that it can be freely rotated. The main shaft 1 is hollow as shown in FIG. 4, and the drive shaft 3 passes through the interior thereof, and the cylinder 16 is fixed to both ends of the drive shaft 3. Each cylinder 16 has a rail 7
Since a pinion 15 is formed which meshes with a rack 8 attached to the rail 7, when the drive shaft 3 is rotationally driven by the motor M, the mechanism section moves by itself along the rail 7.

The motor M in the motor block 9 is rotatable in forward and reverse directions, and selectively drives the main shaft 1 and the drive shaft 3 to rotate. The motor M is connected to the main shaft 1 and the drive shaft 3 by a gear group in a gearbox 10 and a planetary mechanism. The rotation of the motor M is transmitted by a planetary mechanism to either one of a pair of worm shafts 11 and 13 arranged in the gearbox 10, and one of the worm shafts 11 is rotated as shown in FIG. The worm shaft 13 meshes with a worm wheel 12 fixed to one cylindrical body 16, and the other worm shaft 13 meshes with a worm wheel 14 fixed to a shaft 18. An elliptical gear 19 is also fixed to the shaft 18, and this elliptical gear 19 meshes with an elliptical gear 20 fixed to the main shaft 1.

The planetary mechanism exists as a deceleration means and at the same time as a member that selectively transmits the output of the motor M to the main shaft 1 and the drive shaft 3. In the case of
5. Consists of a ball 26 as a planetary gear, an outer race 27 as an internal gear, and a retainer 28 as a planetary carrier, and the inner race 25 is connected to the worm shaft 11.
It is fixed to the outer periphery of a collar 29 which is freely rotatably attached to the collar 29. This collar 29 is provided with a pulley 30 connected to the output shaft of the motor M by a belt 31. In the planetary mechanism configured in this way, the worm shaft 11 is connected to the retainer 28 in the planetary mechanism, and the worm shaft 13 is connected to the outer race 27 via a pulley 34, a belt 33, and a pulley 32.

A brake device as a locking means is installed at one end of each worm shaft 11, 13.
Each brake device is equipped with a solenoid as shown in Figure 8.
A yoke 54 attached to _the gearbox ₁₀ , a core 55 that is integrated with the yoke 54 and faces the end surfaces of the worm shafts 11 and 13, an excitation coil 56, and a yoke. 54 and a spring 57 that biases the core 55 in the axial direction of the worm shafts 11 and 13. When the coil 56 is energized by passing a current through it, the worm shaft 1
The core 55 and the yoke 5 are arranged so that the core 55 is in contact with the movable block 58 fixed to the ends of the
4 is driven by suction against a spring 57. The rotation of the worm shafts 11 and 13 is braked by the connection between the core 55 and the movable block 58.

However, if the solenoid SL ₁ is now energized, the worm shaft 11 will be braked, and the drive shaft 3 will also be locked against this rotation.
In this state, when the collar 29 and the inner race 25 are rotated by the motor M, the balls 26 are prevented from rotating by the retainer 28, which is fixed to the worm shaft 11 and prevented from rotating. Only rotation is performed in the field, and this automaticity is transmitted to the outer race 27, the pulley 32,
Worm shaft 13 via belt 33 and pulley 34,
Then, the main shaft 1 is rotated. Reverse solenoid SL ₂
If you apply braking to the worm shaft 13 by exciting it,
The main shaft 1 is in a locked state, and in this state, since the outer race 27 is locked, the rotation of the motor M is transmitted from the inner race 25 to the worm shaft 11 through the ball 26 that revolves and rotates on its own axis and the retainer 28. , and the drive shaft 3 rotates. As will be described later, these two solenoids SL ₁ and SL ₂ operate selectively to transmit the operation of the motor M to either one of the main shaft 1 to the drive shaft 3, and to lock the other. do.

Now, as is clear from FIG. 4, the wheel body 2 attached to the main shaft 1 includes an inner ring 21 fixed to the main shaft 1,
An outer ring 2 freely rotatably arranged around the outer periphery of this inner ring 21
2, the inner ring 21 is fixed eccentrically to the main shaft 1, and steel balls 24 and a retainer 23 are arranged between the outer ring 22 and the inner ring 21. . Spindle 1 at a predetermined interval
The pair of wheels 2, 2 attached to the main shaft 1 rotate together with the main shaft 1 in a plane orthogonal to the axial direction of the main shaft 1, but both wheels 2 are eccentric by the same amount in the same direction. For this reason, as the main shaft 1 rotates, the amount of protrusion of the wheel body 2 toward the cover sheet 6 side changes. In FIG. 4, the state changes from the minimum protrusion amount shown by the solid line to the maximum protrusion amount state shown by the imaginary line. A permanent magnet 40 is attached to the outer surface of the inner ring 21 of the wheel body 2 on the side of the gearbox 10, so that a pair of reed switches LS ₁ and LS ₂ arranged on the side surface of the gearbox 10 are made to feel the permanent magnet 40 . Here, both reed switches LS ₁ and LS ₂ are arranged at symmetrical positions around the axis of the main shaft 1, and the position of the ring body 2 when the permanent magnets 40 are made to sense both reed switches LS ₁ and LS ₂ is half-way. The reed switch is placed in a rotationally shifted position, and one reed switch is
LS ₁ is sensitive to the permanent magnet 40 when the amount of protrusion of the wheel body 2 toward the cover sheet 6 side is the minimum, and the other reed switch LS ₂ is activated when the amount of protrusion of the wheel body 2 toward the cover sheet 6 side is the maximum. It is designed to be sensitive to the permanent magnet 40 when it is bent, and these constitute a sensor that detects the rotational position of the main shaft 1. A limit switch MS is also attached to the gearbox 10. This is to detect when the mechanism section has reached its limit of movement along the rail 7, and has two normally closed contacts S ₁ and S ₂ , and when the actuator 39 is tilted to one side. When one of the normally closed contacts S ₁ is opened, and when the other is pushed down, the other normally closed contact S ₂ is opened. When the mechanism section runs along the rail 7,
When the mechanism reaches the end of the rail 7, the actuator 39 is driven by projections (not shown) installed at both ends of the rail 7, respectively.

Pine surge using the pine surge device configured as described above is performed with the upper body lying down on the cover sheet ₆ as shown in FIG. At this time, the rotation of the motor M is transmitted to the drive shaft 3, and the pinions 1 at both ends of the drive shaft 3 are locked.
5 and the rack 8, the mechanism portion runs along the rail 7. And at this time, the circular body 2
While freely rotating the outer ring 22, the user presses both sides of the spine of the human body along the spine through the cover sheet 6 to perform a sarasu pine surge to stretch the back. If the rotation of the main shaft 1 is locked in a state in which the amount of protrusion of the wheel body 2 toward the cover sheet 6 side is maximized as shown in FIG. 6, a strong rubbing pine surge can be obtained. From this state, spindle 1
If the main shaft 1 is locked in a state in which it is turned half a turn, that is, in a state in which the amount of protrusion of the wheel body 2 toward the cover sheet 6 side is minimized as shown in FIG. It is possible. The presence of the side rollers 5 makes it possible to more effectively adjust the strength of the pine surge. That is, as shown in FIG. 6, when the amount of protrusion of the wheel body 2 is large, the side roller 5
The height of the side rollers 5 is set so that when the body floats off the ground and the amount of protrusion of the wheel body 2 is small, the height of the side rollers 5 is set so that the body is also supported by the side rollers 5. This reduces the pressure that the body receives from the wheel body 2. changes depending on the presence or absence of contact with the side rollers 5, and this results in further increasing the change in strength.In particular, when making a weak rasuri pine surge, the side rollers 5 as well as the wheel body 2 change. Since it moves in contact with the body, it gently massages a wide range of areas.

Also, in this pine surge device, the solenoid
By energizing SL ₁ , the drive shaft 3 is locked and the rotation of the motor M is transmitted to the main shaft 1.
At this time, the eccentric ring body 2 rotates at a fixed location and the amount of protrusion toward the cover sheet 6 is continuously and periodically changed, so that acupressure pine surge can be obtained.

The operation will be explained in more detail based on the circuit diagrams below. Fig. 9 shows the operating section, and Fig. 10 shows the schematic circuit configuration, which shows a main switch SW ₁ and two operating switches SW ₂ and SW ₃ . Accordingly, the motor M and the solenoids SL ₁ and SL ₂ , which are electromagnetic brake brakes, are controlled via the control circuit section 60. The main switch SW ₁ turns on and off the commercial power supply E, and the switches SW _{2 and SW 3 ,} both of which are 3-position switching types, can be switched independently, and the switch SW ₂ has a middle point. is "off," one end is "up," and the other is "down." Switch SW ₃ has one end set to "shiatsu," the middle point set to "weak," and the other end set to "strong." Here, "shiatsu" causes acupressure pine surge, and "weak" and "strong" cause pine massage. and switch
When SW ₃ is at "Shiatsu", switch SW ₂
If it is set to "off", the acupressure pine surge is set to "up" or "down", the mechanism moves to change the acupressure position without performing the acupressure pine surge. Note that "up" indicates that the mechanism moves toward the head, and "down" indicates that the mechanism moves toward the waist. And Switch SW ₃ is "weak"
Switch SW ₂ is “off” when it is “strong” or “strong”
If so, the pine surge is performed and the mechanism automatically turns over at the end of the rail 7.
Further, when the switch SW ₂ is set to "up" or "down", the pine surge is performed only in the direction determined by "up" or "down" and stops at the end of the rail 7. In other words, switch SW ₃ is used to select between acupressure pine surge and rasping pine surge, switch SW ₂ functions to move the wheel 2 to a predetermined position during shiatsu pine surge, and during rasping pine surge, the smell is automatically reversed. The switch SW 2 functions as a selection switch to select between normal and manual reversal, and the switch SW ₂ is provided with multiple functions to reduce the number of switches and improve operability.

To explain in more detail based on an example of a specific circuit shown in FIG. 11, the motor M is a switching element.
The clockwise or counterclockwise rotation is performed by conduction of either T ₁ or T ₂ . And both switching elements T ₁ , T ₂
becomes conductive when the contacts ry ₁ and ry ₂ of the pair of relays Ry ₁ and Ry ₂ are turned on. These relays Ry ₁ and Ry ₂ and solenoids SL ₁ and GL ₂ , which are electromagnetic brakes, are:
They are controlled by transistors Q ₁ , Q ₂ , Q ₃ , Q ₄ respectively, and each transistor Q ₁ , Q ₂ , Q ₃ , Q ₄ is operated by the output of the logic circuit section. Now Switch SW ₂
is in the "off" position and switch SW ₃ is in "shiatsu"
When the mechanism is not located at the end of the rail 7 and both normally closed contacts S ₁ and S ₂ of the limit switch MS are in the ON state, the inverters I ₁ and I ₂ and the OR gate O ₁ and O ₂ , both inputs of the flip-flop F, which is incorporated with a pair of NOR gates NR ₁ and NR ₂ , are at L level, and both outputs are at H level and L level. These two outputs and the output of switch SW ₃ are input to AND gates A ₂ and A ₃ via AND gate A ₁ , NOR gate NR ₃ , inverter I ₃ and OR gate O ₃ . At this time, both inputs of AND gate _A2 are at H level,
Transistor _Q1 is turned on to rotate motor M clockwise via relay _Ry1 and switching element _T1 . In addition, the H output of inverter I ₄ , the L output of OR gate O ₅ , and the L output of AND gate A ₄ result in a NOR gate.
NR ₄ outputs an H level output, and when transistor Q ₃ is turned on, solenoid SL ₁ is excited. Since this solenoid SL ₁ operates as an electromagnetic brake for the worm shaft 11 , the output of the motor M rotates the main shaft 1 via the planetary mechanism and the worm shaft 13 . Wheel body 2 therefore rotates in a fixed position,
It performs acupressure motion. In addition, this acupressure operation is performed because the mechanical part is located at the end of the rail 7, and the normally closed contact
Regardless of whether S ₁ or S ₂ is open, the output of flip-flop F does not change, or even if the output of flip-flop F changes, the outputs of AND gate A ₁ and OR gate O ₃ do not change, so the operation is exactly the same. Let's do it.

And when Switch SW ₃ is in the shiatsu area,
If switch SW ₂ is set to "up", AND gate A ₂ outputs H level, AND gate A ₃
Although the L level output remains unchanged and motor M continues to rotate clockwise, the output of NOR gate NR ₄ becomes L level due to OR gate O ₅ and AND gate A ₄ , transistor Q ₃ is turned off, and inverter I ₅ turns off the output of NOR gate NR 4. Transistor Q ₄ turns on, solenoid SL ₁ returns, solenoid SL ₂ is energized, and worm shaft 13
Braking is applied to For this reason, at the same time as the main shaft 1 is locked, the clockwise rotation output of the motor M is transmitted to the drive shaft 3 via the worm shaft 11, and the pinion 1
5 and the rack 8, the mechanism moves toward the shoulder. When the wheel body 2 has moved to the desired position, if the switch SW ₂ is turned off, the rotation of the wheel body 2 will begin at that position and the acupressure operation will be resumed.
If switch SW ₂ is set to "down", AND gate A ₂ output goes to L level, AND gate A ₃ output goes to H level, and transistor Q ₂ and relay
Ry ₂ and switching element T ₂ cause the motor M to start rotating to the left, and when the output of the Noah gate NR ₄ goes to L level, the solenoid SL ₂ is turned on, and the left rotation output of the motor M is transferred to the drive shaft 3. I was told this and moved the mechanical part towards my waist. If switch SW ₂ is returned to "off", motor M will rotate clockwise and the solenoid
SL ₁ is energized and starts the acupressure operation again.

The pine surge is performed by setting switch SW ₃ to "weak" or "strong". switch
If SW ₂ is in the ``off'' position, automatic reversing operation is obtained as described above, but when switch SW <sub>3</sub> is set to ``weak'' at the beginning of this operation, reed switch LS ₁ is also When set to "strong", if reed switch LS ₂ is off, motor M starts rotating in either direction depending on the state of flip-flop F, and both inputs of NOR gate NR ₄ are at L level. Therefore, the solenoid SL ₁ is energized, the main shaft 1 is connected to the motor M, and the wheel body 2 is rotated. During this maximum rotation, the permanent magnet 40 attached to the wheel body 2 turns on the reed switches LS ₁ and LS ₂ , so one input of the Noah gate NR ₄ becomes H level, so this output becomes L. solenoid SL ₂ is energized. The rotational output of the motor M is switched to the drive shaft 3, and the main shaft 1 is locked with the amount of protrusion of the wheel body 2 reduced. In this way, switch SW ₃ is set to “weak”
When set to ``Strong'', reed switch LS <sub>1</sub> reduces the amount of protrusion of wheel 2 and the pine surge is performed, and switch SW <sub>3</sub> is set to ``Strong''.
When set to , the main shaft 1 is locked by the reed switch LS ₂ with the amount of protrusion of the wheel body 2 being increased, and in this state the rubbing and pine surge is performed. Then, when the motor M is rotating clockwise and the mechanism is moving toward the shoulder, when this movement reaches the end of the rail 7, the normally closed contact _S1 opens.
For this reason, flip-flop F, which had both outputs at HL, inverts both outputs to LH, and AND gate A ₂ output goes to L level, AND gate A ₃ output goes to H level, and solenoid SL ₂ is energized. The motor M rotates from clockwise rotation to counterclockwise rotation.
The mechanism automatically reverses itself and begins to move down towards the waist. This movement closes the normally closed contact _S1 and changes one input of the flip-flop F, but the output remains unchanged. When the normally closed contact _S2 is opened, the motor M changes from left rotation to right rotation, that is, reverses the direction of movement of the mechanism and continues the pine surge. If switch SW ₃ is set to "weak" or "strong" and switch SW ₂ is set to "up", the motor M will rotate clockwise and the solenoid
SL ₂ becomes excited, and a massage is performed from the waist to the shoulders. When the upper limit is reached and the normally closed contact S ₁ opens, both outputs of the flip-flop F become L level and the output of OR gate O ₃ becomes L level, so the outputs of AND gates A ₂ and A ₃ also become L level, Motor M stops.
If set to "down", the massage will be performed from the shoulders to the waist, and when the lower limit is reached, the motor M will stop. If the switch _W2 is set to the ``off position,'' automatic reversal is performed, and depending on the set positions of ``up'' and ``down,'' manual reversal can be performed within an arbitrary range.

In the embodiment described here, the rotation range of the main shaft 1 is not limited to half a rotation in order to be able to obtain acupressure pine surge due to the rotational drive of the main shaft 1. If acupressure pine surge by rotating the main shaft 1 is not required, there is no problem even if the range in which the main shaft 1 can be rotated is limited to half a rotation, and in this embodiment, the cover of the wheel body 2 2, which is a state in which the rotation of the main shaft 1 is shifted by half a rotation between when the amount of protrusion toward the seat 6 side is the maximum and when it is the minimum.
Lock the main shaft 1 at two positions, and then
Although we have shown a device that can move the spindle 1, we installed a sensor that can detect the rotational position of the spindle 1 more precisely during half a rotation.
By operating the locking means based on the output of this, fine adjustment of the strength may be made.

[Effects of the Invention] As described above, in the present invention, the wheels that move together with the main shaft perform a traversing motion along the back muscles, and the pair of wheels are moved at a predetermined interval in the axial direction. Since the wheel is attached to the main shaft in the body, the wheel can always be in contact with the affected area at the optimal position on both sides of the spine.Moreover, this wheel is eccentric, and the main shaft must rotate at least half a turn. Since it can be rotated between the two, it is possible to change the amount of protrusion from the main axis of the contact part of the ring body with the body, and by this, it is possible to adjust the strength of the sasurimatsu surge. In addition, since the main shaft is equipped with a locking means, the strength settings will not be accidentally shifted, and since a sensor is installed to detect the rotational position of the main shaft, this ensures that the It can be set to perform a strong pine surge or a weak pine surge.
