[0013] FIG. 3 shows an example of a massage machine according to the present invention installed on a chair 12 with arms, which has a seat 12A and a backrest 12B, so that the massage machine can massage the back of a user.

[0014] 3, the lower end 14B of the cover member 14 of the massage machine 10 is placed on the seat 12A near the backrest 12B so as to face the back of the user (not shown), and the massage machine 10 is installed on the chair 12 so that the entire lower surface of the housing 30 (described later) abuts against the backrest 12B. The external dimensions (W×H×T) of the massage machine 10 are set to, for example, approximately 350 mm×671 mm×107 mm, and the total weight is approximately 2.8 kg.

[0015] The massage machine 10 is configured to include a cover member 14 made of an elastic material and having a strip-shaped member 14C that extends longitudinally in the center between the upper end 14T and the lower end 14B, a back shell 22 described later, a housing 30 having an accommodating section 30A that accommodates a treatment block 20 that has a pair of rails 18A and 18B, massage balls 32 including a pair of massage ball units 32A and 32B, and a tapping ball unit 16, and the upper part of which is covered by connecting the cover member 14 as shown in Figure 2, and a remote controller 40 (see Figures 2 and 4) that controls the operation of a brushless motor 70 (see Figure 9) and a brushed DC motor 48 (see Figures 5 and 6) in the treatment block 20 described later.

[0016] As shown in FIG. 1 , the housing 30 has a pair of engagement grooves in an upper end 30T corresponding to the upper end 14T of the cover member 14, into which a pair of positioning protrusions of the back shell 22 engage. A resin, bow-shaped decorative member 28 is fixed to the curved extreme end of the upper end 30T. A metal plate 26 is fixed via an intermediate member 24 to a sloped portion of the lower end 30B corresponding to the lower end 14B of the cover member 14. The housing 30 has an accommodating section 30A surrounded by the upper end 30T and the lower end 30B, a pair of side surfaces connecting the upper end 30T and the lower end 30B, and a bottom surface integrally formed with the upper end 30T, the lower end 30B, and the pair of side surfaces, extending in the longitudinal direction, and formed inside the housing 30. In FIG. 1 , a recess 30H is formed in the left side surface of the pair of side surfaces of the housing 30, into which the remote controller 40 can be detachably accommodated. In FIG. 1, the upper edges of the pair of side surfaces of the housing 30 slope diagonally upward to the right from the portion connected to the upper end 30T toward the lower end 30B, and then slope diagonally downward to the right toward the end of the lower end 30B in accordance with the slope of the lower end 30B.

[0017] Back shell 22 has a relatively large opening in the center, with a pair of positioning protrusions that engage with a pair of engaging grooves in housing 30 at upper end 30T, and is placed on the bottom surface of housing 30. Rail fixing portions are formed at four locations around the periphery of the opening in the inner periphery of back shell 22, to which upper end 18Ae2 and lower end 18Ae1 of rail 18A and upper end 18Be2 and lower end 18Be1 of rail 18B (see FIG. 5) are fixed with machine screws.

[0018] Rails 18A and 18B are each made of, for example, a flexible plastic material, and as shown in a partially enlarged view in Figure 6, have rack gears 18Ara and 18Bra that mesh with pinion gear 54Lb of driven gear 54L (see Figure 7) described below and pinion gear 54Rb of driven gear 54R (see Figure 7).

[0019] As shown in Figures 5 and 6, the treatment block 20 is composed of an upper case 20UC that supports the housing 84 of the hitting ball unit 16, a lower case 20LC that is connected to the upper case 20UC and houses a brushed DC motor 48 and a drive mechanism described later in an internal storage section, and a drive mechanism that oscillates the kneading ball units 32A and 32B and moves the connected upper case 20UC and lower case 20LC along rails 18A and 18B.

[0020] As shown in FIG. 6, the lower case 20LC supports a brushed DC motor 48 that drives the kneading ball units 32A and 32B via a drive mechanism and moves the pounding ball unit 16 and the kneading ball units 32A and 32B along the rails 18A and 18B in the directions indicated by the arrows.

[0021] As shown in FIGS. 1 and 2, the upper case 20UC has a through-hole 20UA into which the housing 84 of the ball unit 16 is inserted.

[0022] Lower case 20LC has passages 20LCa and 20LCb at both ends along the movement direction, spaced a predetermined distance apart, through which a pair of rails 18A and 18B pass. The rails are arranged parallel to each other along the movement direction indicated by the arrow in Fig. 6. Both ends of the pair of rails 18A and 18B are fixed to the rail fixing portions of back shell 22 described above.

[0023] The lower case 20LC has a recess in which the brushed DC motor 48 is disposed formed on the left side of the central partition wall in Figure 6, and on the right side of the central partition wall, three recesses are formed adjacent to each other in a direction perpendicular to the movement direction, in which both end portions and the central portion of the housing 84 of the ball unit 16 are disposed. A plurality of slits are formed in the lower part forming each recess.

[0024] The drive mechanism is composed of a worm wheel 52 with a pinion gear that is engaged with a worm 48WO fixed to the output shaft of the brushed DC motor 48 and is rotatably supported on the lower case 20LC, a transmission gear 58 that has a spur gear that is engaged with the pinion gear of the worm wheel 52 and has a bevel gear portion that is engaged with a bevel gear 56 described later, pinion gears 52L and 52R that are engaged with the above-mentioned driven gear 54L and driven gear 54R, respectively, and a drive shaft 50 to which the bevel gear 56 is fixed.

[0025] The transmission gear 58 is rotatably supported on the lower case 20LC at a position below the drive shaft 50. The bevel gear 56 is fixed to the center between pinion gears 52L and 52R, which are fixed near both ends of the drive shaft 50. Both ends of the drive shaft 50 are rotatably supported together with the driven gears 54L and 54R by rotating shaft and bearing units (described later) fixed to the lower case 20LC. As shown in FIG. 7 , the driven gears 54L and 54R are rotatably supported by rotating shaft and bearing units disposed opposite each other on the inside of both sides of the lower case 20LC. The driven gear 54L includes a spur gear 54La meshing with the pinion gear 52L and a pinion gear 54Lb integrally arranged in parallel with the spur gear 54La. The driven gear 54R includes a spur gear 54Ra that meshes with the pinion gear 52R, and a pinion gear 54Rb that is integrally arranged in parallel with the spur gear 54Ra.

[0026] Furthermore, the drive shaft 50 extends in a direction perpendicular to the above-mentioned movement direction, passing through support bases 62R and 62L that swingably support the swing arms 32AL and 32BL of the kneading ball units 32A and 32B, respectively, and through eccentric cams 60R and 60L that are rotatably supported on the peripheries of the through-holes of the support bases 62R and 62L. The eccentric cam 60L is fixed to the drive shaft 50 between the support base 62L and the bevel gear 56. The eccentric cam 60R is fixed to the drive shaft 50 between the support base 62R and the bevel gear 56. The lower ends of the support bases 62R and 62L abut against the lower case 20LC. As shown in FIG. 11 , the brushed DC motor 48 is driven and controlled by a controller 100, which will be described later. As a result, when brushed DC motor 48 is activated and drive shaft 50 is rotated, eccentric cams 60R and 60L are rotated together with drive shaft 50, and swing arms 32AL and 32BL are swung in the direction indicated by the arrows in Figure 7 by the rotation of eccentric cams 60R and 60L, respectively, in a direction in which the longitudinal center lines of swing arms 32AL and 32BL intersect at a predetermined inclination angle, for example, approximately 13°, with respect to the axis of drive shaft 50 (see Figure 6).

[0027] The massaging ball unit 32A comprises a pair of roughly truncated cone-shaped massaging balls 32AU and a swing arm 32AL connected to the pair of massaging balls 32AU. The massaging ball unit 32B comprises a pair of roughly truncated cone-shaped massaging balls 32BU and a swing arm 32BL connected to the pair of massaging balls 32BU. The lower portions of the swing arms 32AL and 32BL are connected to the upper portions of support bases 62R and 62L with bolts and nuts (not shown) and supported so as to be swingable, so that the center lines of the longitudinal directions of the swing arms 32AL and 32BL intersect with the axis of the drive shaft 50 at a predetermined inclination angle, for example, approximately 13°.

[0028] As shown in FIGS. 8 and 9, the hitting ball unit 16 includes a pair of hitting balls 88R and 88L that hit the back of the user, piston members 74R and 74L having connecting portions 92R and 92L that are connected to the hitting balls 88R and 88L, respectively, by machine screws Bs1 (see FIG. 10), piston housings 86R and 86L that guide and accommodate the connecting portions 92R and 92L of the piston members 74R and 74L, respectively, a housing 84 that includes cylindrical portions 84R and 84L that position and accommodate the piston housings 86R and 86L within hollow portions 84HR and 84HL, respectively, and a dual-shaft brushless motor 7 disposed below the approximate center of the housing 84. 10, the brushless motor 70 includes crank members 72R and 72L connected to output shafts 70SA and 70SB of the brushless motor 70 and connected to the lower portions of the piston members 74R and 74L via bearing members 76R and 76L, bearing members 76R and 76L inserted into holes in the lower portions of the piston members 74R and 74L to rotatably support shafts 72Re and 72Le of the crank members 72R and 72L, a magnet holder 80 connected to the crank member 72R and holding an encoder magnet (not shown) so that it rotates concentrically with the axis of the output shaft 70SA, and a motor support component 90 for fixing the inner rotor of the outer rotor brushless motor 70. As shown in FIG. 10, bearing members 78R and 78L rotatably supported by support shafts 74Rs and 74Ls are provided above the bearing members 76R and 76L on the piston members 74R and 74L, respectively.

[0029] Since the piston housings 86R and 86L have the same structure, the structure of the piston housing 86L will be described, and a description of the piston housing 86R will be omitted.

[0030] As shown in FIG. 10 , the piston housing 86L has a neck portion 86La at its upper end that movably guides the outer periphery of the connecting portion 92L, and accommodates the piston member 74L therein. The lower end of the piston housing 86L is fixed to the inner periphery of the cylindrical portion 84L of the housing 84. A rubber ring 94L is provided on the outer periphery of the connecting portion 92L at the inner periphery of the piston housing 86L. A rubber ring 94R ​​(not shown) is provided on the outer periphery of the connecting portion 92R at the inner periphery of the piston housing 86R (not shown). As a result, when the brushless motor 70 in the hammering ball unit 16 is subjected to a high load, the swing angle of the piston member 74R and the piston member 74L is limited within a predetermined range due to the sliding contact of the bearings 78R and 78L with the inner peripheries of the piston housings 86R and 86L and the elastic force of the rubber rings 94L and 94R.

[0031] A slot 86Ln formed on the outer periphery of the piston housing 86L is engaged with a protrusion 84HLp formed on the inner periphery of the cylindrical portion 84L of the housing 84.

[0032] Output shafts 70SA and 70SB of brushless motor 70 are rotatably supported by bearings 82 provided in bearing pedestals 84R and 84L, respectively. As shown in Fig. 11, brushless motor 70, which has brush position sensor 78S, is driven and controlled by controller 100, which will be described later. As a result, when brushless motor 70 is activated and crank members 72R and 72L are rotated, connecting portions 92R and 92L of piston members 74R and 74L are raised and lowered by a predetermined stroke together with a pair of striking balls 88R and 88L, causing the pair of striking balls 88R and 88L to strike the back of the person to provide treatment.

[0033] In addition to this configuration, as shown in FIG. 11, the massage machine 10 is equipped with a controller 100 that controls the operation of the brushed DC motor 48 and brushless motor 70 of the massage machine 10 based on a group of bidirectional signals RD from the controller 40C of the remote controller 40.

[0034] As shown in FIG. 4, the remote controller 40 has an operation unit 40F which is formed from, in order from the top to the bottom, a power button with LED 40PB1, an emergency stop button 40PB2, a full range button with LED 40PB3 which performs a massage from the back to the waist in automatic mode, an upper button with LED 40PB4 which performs a massage focusing on the upper back, a lower button with LED 40PB5 which performs a massage focusing on the area from the lower back to the waist, a + button 40PB6 which increases the vibration level of the pair of hitting balls 88R and 88L between levels 0 and 8 (8 levels), a - button 40PB7 which decreases the vibration level, a mode switching button 40PB9 which, when pressed and held, switches from automatic mode to manual mode and moves the pair of hitting balls 88R and 88L to the desired position to perform the hitting action, and a mode switching button 40PB8. When the mode switching button 40PB8 or the mode switching button 40PB9 is pressed for a short period of time, the automatic mode is stopped and the operation of the pair of hitting balls 88R and 88L is switched to the manual mode. When the mode switching button 40PB8 and the mode switching button 40PB9 are pressed and held, the striking positions of the pair of striking balls 88R and 88L are moved up and down, and when the finger is released from the mode switching button 40PB9, the pair of striking balls 88R and 88L start operating at the specified positions to which they have been moved.

[0035] 11, the above-mentioned operation unit 40F is electrically connected to a controller 40C provided on a control board (not shown) disposed inside the remote controller 40. The controller 40C is connected to a push button control unit 40SC that supplies the controller 40C with a group of control signals corresponding to the operation of the operation unit 40F, an LED lamp display control unit 40I that turns on or off an LED based on the group of control signals corresponding to the operation of the operation unit 40F, a wireless signal transceiver 40T that transmits and receives a group of bidirectional signals RD from a wireless signal transceiver 100T of the massage machine 10, and a battery (dry cell) 40B. The controller 40C is provided with a memory 40M that stores predetermined program data including control of LED display, data representing the ID of a device (massage machine 10) to be paired as a destination ID of a pairing request signal related to the pairing operation between the remote controller 40 and the massage machine 10, and program data for controlling the operation of the wireless signal transceiver 40T.

[0036] A controller 100 is provided on a control board (not shown) inside the massage machine 10 and controls the operation of the brushed DC motor 48 and the brushless motor 70. Two up / down stroke position limit sensors 104, which are required for movement control of the treatment block 20 and detect the position of the treatment block 20 on the rail 18B, are provided at predetermined positions with a predetermined distance between them, for example, on the right end of the lower case 20LC of the treatment block 20 facing the rail 18B shown in Fig. 6. In addition, induction magnets (not shown) are provided at the upper end 18Be2 and the lower end 18Be1 of the rail 18B, respectively.

[0037] The brushed DC motor 48, the brushless motor 70, and the up / down stroke position limit sensors 104 are electrically connected to the controller 100. The brushless motor 70 includes a brushless motor 78M and a brush position sensor 78S. The controller 100 is supplied with detection output signals from the two up / down stroke position limit sensors 104.

[0038] The controller 100 is provided with a memory 100M for storing program data for controlling the vibration level of the pair of hitting balls 88R and 88L generated by the brushless motor 70 within a range of level 0 to level 8 (8 levels), program data for controlling the operation of the massaging balls 32AU and 32BU generated by the brushed DC motor 48, program data for controlling the operation of the wireless signal transmitter / receiver 100T, and data representing the ID of the device (remote controller 40) to be paired as the sender ID of the pairing request signal related to the pairing operation between the remote controller 40 and the massage machine 10, as well as program data.

[0039] When the massage machine 10 is connected to a power source via the DC adapter 102, the controller 40C sends a pairing request signal to the wireless signal transceiver 100T through the wireless signal transceiver 40T by simultaneously pressing the emergency stop button 40PB2 and the - button 40PB7 for approximately two seconds. This causes the LED lamp display control unit 40I to blink the LED. The determination unit of the controller 100 determines based on the pairing request signal that the data representing the ID of the pairing partner device (remote controller 40) serving as the sender ID stored in the memory 100M matches the data. After the power plug of the massage machine 10 is unplugged from the outlet and then plugged back into the outlet, the notification unit of the wireless signal transceiver 100T supplies a notification signal indicating that pairing has been completed to the wireless signal transceiver 40T. At this time, the LED of the LED-equipped power button 40PB1 of the remote controller 40 is turned off.

[0040] After the pairing is completed, when the LED-equipped power button 40PB1 is pressed to operate the massage balls 32AU and 32BU of the massage machine 10, the controller 40C transmits a signal group RD to the wireless signal transceiver 100T via the wireless signal transceiver 40T to perform a back-to-lower back massage in automatic mode and set the vibration level of the pair of hammering balls 88R and 88L to level 1. The controller 100 controls the rotation speed of the output shafts 70SA and 70SB of the brushless motor 70 by adjusting the output voltage of the brushless motor 70 based on the signal group RD. By adjusting the output voltage of the brushless motor 70, the vibration level (corresponding to the number of rotations per minute of the output shaft of the brushless motor 70) is adjusted. When level 8 to level 0 (minimum level stopped state) are set by operating the + button 40PB6 and the - button 40PB7, for example, the revolutions per minute (rpm) of the output shaft of the brushless motor 70 are set to 1800, 1500, 1430, 1280, 1030, 850, 650, 450, and 0, respectively. When the + button 40PB6 is operated to select level 8, or when the - button 40PB7 is operated to select level 0, the LED of the LED-equipped power button 40PB1 lights up twice to alert the user that the vibration level is at the maximum or minimum level.

[0041] When mode switching button 40PB8 or mode switching button 40PB9 is pressed for a short period of time, controller 40C stops the automatic mode and transmits signal group RD to wireless signal transceiver 100T via wireless signal transceiver 40T to operate pair of striking balls 88R and 88L in manual mode. First, to operate pair of striking balls 88R and 88L at level 1, controller 100 adjusts the output voltage of brushless motor 70 based on signal group RD, thereby controlling the rotation speed of output shafts 70SA and 70SB of brushless motor 70.
