Detailed Description of the Invention [Industrial applications]

The present invention relates to a massage machine that includes a treatment element having a function of a tapping massage operation and that the operation position of the treatment element is variable.

[Prior art]

In this type of massage machine, when the treatment element is made to perform a tapping massage operation and the operation position is variable, a tapping rolling massage operation can be obtained in which the massager makes a tapping massage while moving. Then, in the case of providing an automatic treatment function that sequentially executes treatment operations at a plurality of locations based on a preset program, if the above-mentioned tapping rolling massage operation is included in the automatic treatment operation, a massage effect is obtained. It can be higher.

[Problems to be Solved by the Invention]

However, since the tapping massage action is effective against the shoulder, the stimulus given to the user is relatively strong, and especially when the tapping massage is performed on the head and neck, the head is massaged. It will be quite shaken. For this reason, if a tapping rolling massage operation is included in the automatic treatment operation, and this operation is started from the head or neck, as shown by the broken line in FIG. I was very surprised because my head would be shaken as soon as the massage was started. The present invention has been made in view of such points,
It is an object of the present invention to provide a massage machine which allows a user to comfortably receive a massage when enhancing a massage effect including a hitting rolling massage operation during an automatic treatment operation.

[Means for Solving the Problems]

Thus, the present invention is provided with a treatment element capable of a pounding massage operation and capable of performing an operation position changing operation in parallel with the pounding massage operation, and at the operation position and the operation time according to a preset program. In a massage machine having a control circuit having an automatic treatment function for sequentially performing a treatment operation by a treatment element, the control circuit automatically performs a tapping rolling massage operation that causes the treatment element to move while moving the treatment element. It is characterized in that it is included in the operation and the start position of this tapping rolling massage operation is set to a position corresponding to a site other than the head and neck. [Operation] According to the present invention, since the operation of performing a hitting massage while the treatment element is moving starts from a place other than the head or neck, the head is not suddenly shaken. [Examples] The present invention will be described in detail below based on illustrated examples. First, the mechanical point of a massage machine capable of tapping massage and in which the operating position of the treatment element 5 is variable will be described. This massage machine is incorporated in a treatment table such as a backrest of a chair or a bed. The treatment element can be freely moved along the backrest or bed. Here, as shown in FIG. 5, the treatment element is incorporated into a reclining backrest of a chair. This chair is provided with a seat 82 and an armrest 83 on a lower frame 81 framed by a pipe, and a frame 85 of a backrest 84.
The lower part of the frame is pivotally attached to the lower frame 81, and the lower end of the frame 85
A gas spring 86 is attached between 81, and the backrest 84 can be reclined by expanding and contracting the gas spring 86 by operating a lever 87 provided on the side of the armrest 83. A pair of rails 90, 90 having a character shape and opening surfaces facing each other are fixed. Further, a headrest 88 is provided on the upper end of the backrest 84, and support bands 89 are provided in the up-down direction on both sides of the back surface of the cover sheet provided up to the headrest 88 on the front surface of the backrest 84. The pair of rails 90, 90
Racks 91 and 91 are fixed to the opening edges of the rails along the longitudinal direction, respectively, and are provided with rollers 18 rolling between the rails 90 and 90, and a pinion 17 that meshes with the rack 91. There is a massage machine installed. As shown in FIG. 6, the massage machine is provided with a motor block 20 at one end and a speed reducer block 19 at the other end, and the rollers 18 and the pinion 17 driven to rotate are projected from both blocks 20 and 19. The main shaft 1, the screw shaft 14, and the auxiliary shaft 13 are installed between the blocks 20 and 19. And the auxiliary shaft 1 whose both ends are supported by both blocks 20 and 19
The main shaft 1, the screw shaft 14, and a rotary shaft 12 parallel to the auxiliary shaft 13 are attached to the auxiliary shaft 3 through a pair of rotary plates 15 and 15 which are rotatable with respect to the auxiliary shaft 13. The rotating shaft 12 is rotatable around the shaft 13.
The rotary shaft 12, which is supported by the pair of rotary plates 15 and 15 at both ends and is rotatable with respect to the rotary plate 15, has a pair of crank shafts 12a and 12b whose eccentric directions are opposite to each other.
Are connected in the axial direction to function as the eccentric member 7, and the non-eccentric portions 12d and 12e at both ends are supported by the rotary plate 15. The motor housed in the motor block 20 drives the main shaft 1, the screw shaft 14, the rotary shaft 12, and the pinion 17 to rotate, and also rotates the rotary shaft 12 around the auxiliary shaft 13.
That is, a driven shaft 31 disposed on the outer surface of the speed reducer block 19 is connected to a pulley 28 mounted on the output shaft of a motor protruding below the motor block 20 via a belt 29 and a pulley 30. , Driven shaft 31 and reducer block 19
The internal deceleration mechanism is connected to the clutch 33 by the pulleys 34, 36 and the belt 35. The speed reducing mechanism section (not shown) in the speed reducer block 19 is composed of a speed reducing section and a plurality of clutch sections, and when the clutch 33 is connected,
The motor output is selectively transmitted to the main shaft 1, the screw shaft 14, or the pinion 17. Further, via the clutch 32, the pulley 37, the belt 38, the pulley 39, and the worm 40 to the driven shaft 31,
A worm wheel 41 mounted on the auxiliary shaft 13 is connected, and a gear 42 integrated with the worm wheel 41 meshes with a gear 43 fixed to the non-eccentric portion 12d of the rotary shaft 12. When the clutch 32 is connected, the motor output is transmitted to the rotary shaft 12 via the above-mentioned members, and the rotary shaft 12 rotates about the shaft. Further, a feed screw 25 connected to the motor via pulleys 21 and 23, a belt 22 and a clutch 24 is provided on the outer surface of the motor block 20, and a feed nut 26 screwed to the feed screw 25 is provided. One of the pair of rotary plates 15 and 15 is connected by a link 16. When the feed screw 25 rotates at the motor output, the feed nut 26 that moves in the axial direction of the feed screw 25 moves the rotary plate 15 via the link 16, and as a result, is supported by the rotary plate 15. The rotary shaft 12
Rotate around the auxiliary shaft 13. A pair of inner rings 2, 2 are attached to the main shaft 1 at intervals. Both inner rings 2, 2 are eccentric to the main shaft 1 in the same direction by the same amount and are inclined in opposite directions,
By engaging with the protrusion 11 formed on the main shaft 1, the main shaft 1 is rotated together with the main shaft 1 and is slidable in the axial direction of the main shaft 1. It is installed so that it can be reversed. Further, one end of each connecting arm 6, 6 is rotatably connected to the outer peripheral surface of the non-eccentric portion of each inner ring 2, 2. The connecting arm 6, which is adapted to slide the main shaft 1 in the axial direction together with the inner ring 2, is screwed with the screw shaft 14. In addition, since the connecting arms 6 and 6 are respectively screwed into the portions of the screw shaft 14 in which the screw directions are reversed, as the screw shaft 14 rotates, the connecting arms 6 and 6 are The pair of inner rings 2, 2 are moved closer to or farther from each other. Middle portions of the arms 4, 4 are fixed to the outer rings 3, 3, respectively. Then, at the bent portion of the tip of each arm 4, the arm 4
A roller-shaped massaging element 5 which is freely rotatable is attached to each of them, and the other end of one arm 4 is connected to the crankshaft 12a of the rotary shaft 12 via the connecting link 8 and the sphere 70.
The other end of the other arm 4 is connected to the crankshaft 12b of the rotary shaft 12 via the connecting link 8 and the spherical body 70. The spherical body 70 here is attached so as to be slidable in the axial direction with respect to the rotary shaft 12, and includes the connecting link 8 and the crankshaft.
The engagement with 12a, 12b is made by enclosing the sphere 70 at one end of the connecting link 8. For this purpose, the connecting link 8
Is freely rotatable in three dimensions with respect to the crankshafts 12a and 12b, and the connecting portion between the other end of the connecting link 8 and the arm 4 is also formed as a ball joint 44.
Similarly, it can freely rotate in three dimensions. Also, the rotation axis
The central non-eccentric part 12c 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 will be described. When the main shaft 1 is rotated by the motor, the inner ring 2 that rotates together with the main shaft 1 is eccentric and inclined with respect to the main shaft 1. Therefore, the inner ring 2 is attached to the outer ring 3 that is freely rotatable. The treatment element 5 attached via the arm 4 has a motion limited to the movement of the arm 4 by the connecting link 8, and thus a movement that draws a three-dimensional trajectory along with the rotation of the spindle 1. That is, the movement is performed to change the position in the vertical direction, the axial direction of the spindle 1, and the protruding direction from the spindle 1. The pair of massaging elements 5, 5 that perform such movement symmetrically give a so-called "nerve massage" to the back surface of the user.
In addition, this "nerve massage" takes two forms depending on the rotation direction of the main shaft 1, a "rubbing up" massage and a "rubbing down" massage, which will be described later. Further, the connecting link 8 connected to the arm 4 via the ball joint 44 is swung up and down and left and right as the inner ring 2 rotates, but the connecting link 8 and the rotary shaft 12 form a ball joint. Since the spherical bodies 70 are connected, the operation of the treatment element 5 is smoothly performed. By rotating the feed screw 25 by the motor, the rotary shaft is rotated around the auxiliary shaft 13 via the link 16 and the rotary plate 15.
When 12 is rotated, the arm 4 and the outer ring 3 are accompanied by this.
Rotates around the inner ring 2, and the treatment element 5 changes the amount of protrusion in the front direction in which the back surface of the user is located. Therefore, when the massage is performed by rotating the spindle 1, When the amount of protrusion is large, a strong "nerve" massage is performed, and when the amount of protrusion is small, a weak "nerve" massage is performed. By adjusting the amount of protrusion, it is possible to massage the shoulder from above rather than from the back. When the rotating shaft 12 is rotated instead of the main shaft 1, since the arms 4 are connected to the crankshafts 12a and 12b, which are the eccentric parts of the rotating shaft 12, through the connecting links 8,
In this case, the connecting link 8 that is moved along with the eccentric rotation of the crankshafts 12a and 12b moves the arm 4 that is connected by the ball joint 44, and the movement of the arm 4 at this time is that of the inner ring 2 that has stopped. Since the movement moves around the outer ring 3 together with the outer ring 3, the treatment element 5 at the tip of the arm 4
Although it depends on the position of the inner ring 2, when viewed from the front, a straight line reciprocating motion in the up-and-down direction is performed, and a pounding massage is performed. Further, since the eccentric directions of the crankshafts 12a and 12b of the rotary shaft 12 which is the eccentric member 7 are opposite by 180 °, the tapping massage operation is alternately performed on the massaging elements 5 and 5. When the pinion 17 is rotated by the motor, the rack 91 and the pinion 17 mesh with each other, so that the massage machine moves the backrest 84 of the chair, which is the 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, it is possible to obtain a rolling massage in which the treatment element 5 touches the back surface of the human body. When the screw shaft 14 is further rotated, the treatment element 5 moves to the main shaft 1
The axial position of the treatment element 5, that is, the width of the treatment element 5, depends on whether the region to be treated is a shoulder, a neck, or the like in order to move the treatment element 5 in the axial direction and change the interval between the pair of treatment elements 5, 5. You can change the position of the direction. Then, when the tapping massage operation by rotating the rotary shaft 12 around the axis is executed in parallel with the moving operation by the rotation of the pinion 17, the massaging element 5 performs the tapping operation while moving up and down. It is possible to obtain a “massage”, that is, a massage in which the part giving the tapping motion changes up and down sequentially. Next, the operation device 60 that gives an operation command to the massage machine will be described. As shown in FIG. 1, the operating device 60 includes a main body 61 having an elongated rectangular shape, and a cover 62 arranged on the front surface of the main body 61 and slidable in the longitudinal direction of the main body 61. The length of 62 in the sliding direction is shorter than half the length of the main body 61 in the longitudinal direction. A portion of the surface of the main body 61 that is not included in the slide area of the cover 62 is provided on one end side of the main body 61, and this portion has an "operation / stop" switch commonly used in both the automatic treatment mode and the manual treatment mode. SW ₀₁ and storage switch
SW ₀₂ and is provided. In addition, in the part near the center of the surface of the main body 61, "upper body course", "neck / shoulder course", "waist course" used in the automatic treatment mode,
"Short" and "shoulder alignment" switches SW _{11 to} SW ₁₅ are provided, and "motion selection", "strong", and "weak" used in the manual treatment mode are located near the other end. ,
"Up", "Down", "Wide", "Narrow" switches
SW _{21 to} SW ₂₇ are provided, and a “leg vibration” switch SW ₀₃ is provided at the center of the main body 61 in the longitudinal direction. This switch SW ₀₃ is for the vibration massage machine for legs included in the foot rest additionally used for the massage machine. Since it is an additional function commonly added in both treatment modes, the cover SW ₀₃ The cover 62 is prevented from being covered when the slide member 62 is slid in either direction. Further, an operation mode discriminating switch S formed by a reflection type photoelectric switch composed of a light emitting element and a light receiving element is arranged at a portion on one end side of the main body 61, and the switch SW
_01, the switch SW _03, a light-emitting element _{L 01, L 03, L 11} ~L 15 respectively corresponding to the switch SW ₁₁ to SW _15, is selected by the switch SW ₂₁ of the "operation selection" in the manual therapy mode "sideburns" , Light emitting elements L _{21 to} L corresponding to each of the operations of “brush down”, “rolling”, “partial rolling”, “tataki”, “tataki rolling” and “partial tat rolling”
₂₇ , and the light-emitting element L ₁ indicating that it is in the automatic treatment mode
And a light emitting element L ₂ indicating that the manual treatment mode is set. The above-mentioned "partial rolling" and "partial tapping rolling" mean rolling massage and tapping rolling massage in which the movement range of the treatment element is limited to a small range. Then, the operation device 60 sends out a required code to the control circuit CPU provided on the body side of the massage machine according to the type of the pressed switch. This control circuit CPU includes the motor M and the clutches 24, 31, 3
A vertical position sensor S that controls the drive circuits DC ₁ and DC ₂ for 2 and the like and detects the vertical position of the treatment element 5
₁ and a width position sensor S that detects the position of the treatment element 5 in the width direction.
₂ is connected to a protrusion position sensor S ₃ that detects the protrusion amount of the treatment element 5, and the upper body course, the neck / shoulder course, and the waist course in the automatic treatment mode are connected.
A course table CT is provided for each course. Each of the above position sensors S ₁ , S ₂ , S ₃ is composed of, for example, a rotary encoder, a photoelectric switch, or the like, and here, as the vertical position sensor S ₁ , 5 bits Y ₁ ~
A width position sensor S ₂ can detect Y ₃₂ in 32 steps, and a 2-bit protrusion position sensor S ₃ can detect 8 steps of X _{1 to} X ₈ in ₃ bits. In Z ₁
The one that can detect the position in 4 steps from ~ Z ₄ is used. The course table CT in the control circuit CPU is written with a large amount of operation information about what kind of massage is performed at which position and for what kind of time (number of times) for each course.
The automatic treatment mode is realized by sequentially reading out the operation information of 1 and causing the treatment element 5 to execute the operation information. However,
The upper and lower positions of the motion information written in the course table CT are not directly reflected in the upper and lower positions of the treatment element 5, but as a position corrected according to the output of the switch SW ₁₅ for shoulder position adjustment. It is supposed to be. TP in FIG. 2 is a table pointer indicating which stage of motion information is currently being operated, SCF is a shortening flag that is inverted based on the operation of the shortening switch SW ₁₄ , C ₁ ,
C ₂ is a counter that counts the number of fir tree and the tapping time. Then, in order to perform the operation in the automatic treatment mode by the operation device 60, as shown in FIG. 1 (a), the cover 62 is slid downward and the switch group corresponding to the manual treatment mode is moved. After covering the cover with the cover 62, press the "Start / Stop" switch SW ₀₁ . Along with this operation, the automatic treatment mode is set by the output of the operation mode determination switch S, the light emitting element L ₁ is lit up, and the light emitting element L ₁₅ adjacent to the “shoulder alignment” switch SW ₁₅ is displayed. Flashes. And the treatment element is moved to a vertical position in accordance with the setting of "shoulder alignment" switch SW _15, if this movement has been completed, and turns on the light-emitting element L _15, lowering seen in situ treatment element 5 operation To perform. After this,
If any of the three types of courses that are set in the automatic therapy mode is selected by the switch SW ₁₁ to SW _13, and then execute a series of massage operations of the corresponding courses sequentially. At this time, the control circuit CPU compares the current position information of the treatment element 5 by the position sensors S ₁ , S ₂ , and S ₃ with the position information in the motion information written in the course table CT, The position of the treatment element 5 is changed step by step. When the "shortening" switch SW ₁₄ is pressed, the massage operation of the step currently being executed or the massage operation of the step to be designated next is performed in a partially omitted state. As shown in FIG. 1 (b), the cover 62 is moved to
If you press the "Start / Stop" switch SW ₀₁ with the cover 62 covering the switch group corresponding to the automatic treatment mode,
The output of the operation mode determination switch S in the cover 62 is changed to set the manual treatment mode, the light-emitting element L ₂ is turned on, and the light-emitting element L ₂₁ is turned on to cause the treatment element to “brow up” on the spot. To start. Then, if the "motion selection" switch SW ₂₁ is pressed and a massage motion of the seven types in the illustrated example is selected,
The light emitting elements L _{21 to} L ₂₇ of the designated type are turned on and the massager is caused to perform a massage operation. At this time, the strength of the massage and the massage position can be adjusted by the switches SW _{22 to} SW ₂₇ . Further, when the cover 62 is moved to the automatic treatment mode while the manual treatment mode is being operated, or conversely, when the cover 62 is moved to the manual treatment mode when the automatic treatment mode is being operated, In the description of the operation of each treatment mode, the same operation as when the "start / stop" switch SW ₀₁ is operated is started. Further, if the "operation / stop" switch SW ₀₁ is pressed during operation, the treatment element is stopped on the spot, and when the "storage" switch SW ₀₂ is pressed, a storage operation is performed to move the treatment element to the storage position. . By the way, in massage, it is preferable to first loosen the body with a lightly stimulating massage instead of suddenly giving a strong stimulating massage.Therefore, even in the automatic treatment operation, the rolling massage, which is the lightest massage, is performed first. A tapping rolling massage is performed, and then, a kneading massage that gives the strongest stimulation is given, and in the final stage of the automatic treatment operation, conversely, a tapping rolling massage is performed and then a rolling massage is performed to finish. . Here, when performing the rolling massage and the tapping rolling massage, the control circuit CPU of this massage machine starts the rolling massage shown by the solid line from the neck to the waist as shown in FIG. The motion of returning from the waist to the neck by the tapping rolling massage is repeated multiple times so that the tapping rolling massage does not start from the neck. Since the tapping rolling massage starts from the waist and moves upwards to reach the neck, the user can fully predict that the tapping massage for the neck will start. Even if the head is shaken by, the user will not be surprised. When the tapping rolling massage is performed from the upper side to the lower side, as shown in FIG. 4, the tapping rolling massage may be started at a position lower than the neck portion. In the manual treatment mode, the user selects the beating massage or the beating rolling massage by his / her own will, so the control circuit CPU does not give the above-mentioned restrictions, and starts from the beating massage at the neck or the neck. I am able to perform a hitting rolling massage.

【The invention's effect】

As described above, in the present invention, since the tapping rolling massage operation is included in the automatic treatment operation, the effect of the massage is further enhanced, and this tapping rolling massage is applied to a part other than the head and neck. Since it is designed to start from the corresponding position, the user does not be surprised when the beating massage for the head and neck is suddenly started and the head is shaken, It can be used comfortably.
