Description

  The present invention relates to a massage device for massaging the back of a user who is supine on the top.

  2. Description of the Related Art There is known a massage device that massages a user's back by a massage roller by reciprocatingly driving a massage roller along a predetermined direction. In this type of massage device, a mattress type that can receive treatment on the entire back when the user is supine and a chair type that can receive treatment on the upper part from the waist on the back while sitting Things are known.

  As a massage device that can massage the entire back of the user, run a massage unit with a massage roller from the entire back of the user who is supine, that is, from the neck of the user to the heel of the leg However, it is known that a mattress type massage device has a higher massage effect than a chair type massage device.

  Conventionally, the massage unit is provided so as to be reciprocally driven along the longitudinal direction on the upper surface of the body of the massage apparatus covered with an exterior. The massage unit has a holding body. The holding body includes a squeezing roller that squeezes both sides of the vertebral column on the back of the user at the center in the width direction intersecting the running direction, and both sides of the squeezing roller. A side roller for massaging a portion outside the portion massaged by the massage roller on the user's back is provided.

  Specifically, the holder is provided with a roller shaft along the width direction, and the roller shaft is rotationally driven by a drive source provided at one end thereof. A pair of arm bodies having the stagnation rollers at both ends in the longitudinal direction are provided on the roller shaft at predetermined intervals so as to swing in a direction in which one end and the other end are brought into contact with and separated from each other via an eccentric cam body. The side roller is rotatably supported on the roller shaft outside the body.

JP 2001-299851 A

  When the user receives a massage on the back of the body, the roller unit is reciprocated with respect to the longitudinal direction of the main body, and when the massage is received over the entire back surface, or the roller unit is reciprocated with respect to the longitudinal direction of the main body. However, the massage unit is stopped in the middle of the reciprocating movement or at a predetermined position such as a part designated by the user, and a stronger massage is given to a specific part of the body such as the waist and thighs than other parts. There is a case to do so.

  When a specific part of the body receives a stronger massage than the other part, if the reciprocating motion of the massage unit is stopped and the roller shaft is rotated, a pair of arm bodies having the squeezing rollers is formed by the roller shaft. Since it swings, the user can receive a sufficient massage at a specific part of the body by the squeezing roller as compared with other parts.

  However, since the side roller is rotatably supported by the roller shaft, it does not rotate integrally with the roller shaft. Therefore, even if the user can receive a sufficient massage with the massage roller, the user cannot receive the massage with the side roller.

  In other words, both sides of the spine on the user's back can be massaged by the squeezing roller, but the part outside the part that can be massaged by the squeezing roller can receive massage with sufficient strength. There was something I couldn't do.

  This is not only when the massage unit is stopped, but also when it is reciprocated along the longitudinal direction of the main body, and the side roller rotates due to contact resistance with the inner surface of the exterior covering the main body. Therefore, there is a case in which the user cannot perform a massage with sufficient strength as compared with the case where the side roller is forcibly driven to rotate.

  This invention enables the side roller to rotate integrally with the roller shaft together with the squeezing roller, so that the user can perform massage with sufficient strength by the side roller, similar to the massaging action by the squeezing roller. The object is to provide a massage device which can be received.

Can be attached to the fastener. As a result, the massage device M can be held in a folded state.

  Next, the roller unit 17 will be described. 7 is a plan view of the roller unit 17, FIG. 8 is a bottom view, FIG. 9 is a front view, FIG. 10 is a longitudinal sectional view, and FIG. 11 is a right side view. The roller unit 17 has a pair of left and right side frames 27. In the pair of side frames 27, both end portions in the width direction at the lower end are connected by a pair of connecting shafts 28. A pair of left and right side frames 27 and a connecting shaft 28 connecting them constitute a holding body 30 for the roller unit 17.

  The wheels 29 that roll on the running surfaces 4e of the pair of guide rails 4 are rotatably attached to both ends of the connecting shaft 28.

  A pair of receiving portions 31 a formed on the lower surfaces of both ends in the width direction are engaged with the connection shaft 28 at the center in the axial direction of the connection shaft 28, that is, in the center in the width direction of the roller unit 17. It is fixed.

  The support 31 has a substantially triangular side surface, and a support hole 32 is formed at the top as shown in FIG. In the support hole 32, a middle portion in the axial direction of the roller shaft 33 is inserted and supported rotatably.

  As shown in FIG. 10, one end and the other end of the roller shaft 33 are rotatably supported by support holes 27 a formed in the pair of side frames 27. A gear 34 is fitted to one end of the roller shaft 33 that protrudes into one side frame 27, and the gear 34 is a second drive source 35 (see FIG. 5) that is a pulse motor provided in the one side frame 27. 7 is meshed with a gear (both not shown) provided on the output shaft of a broken line. Accordingly, the roller shaft 33 is rotationally driven by the second drive source 35.

  As shown in FIG. 11, a thin strip-shaped detection member 36 is provided at the other end of the roller shaft 33 so as to protrude radially outward. The detection member 36 rotates with the roller shaft 33 and is detected by an optical sensor 37 provided on the side frame 27.

  When the rotation drive of the roller shaft 33 by the second drive source 35 is stopped, the second drive source 35 is set after the detection member 36 is detected by the optical sensor 37 after receiving the stop signal. The roller shaft 33 is rotated and stopped by the number of pulses. Thereby, the roller shaft 33 can always be stopped at the same rotation angle.

  A pair of auxiliary massage rollers 38 are rotatably supported on both sides of the support 31 of the roller shaft 33. On both sides of the pair of auxiliary massage rollers 38 of the roller shaft 33, massage massage portions 41 are provided.

  The massage massage part 41 has a pair of arm bodies 42. As shown in FIGS. 10, 13, and 14, the arm body 42 is attached to the first member 43 provided with a flange 43 a over the entire length of the peripheral portion and the flange 43 a of the first member 43. The second member 44 is provided.

  A squeezing roller 45 is rotatably supported on the upper part in the height direction at both ends in the longitudinal direction of the first member 43. Each stagnation roller 45 has wear resistance and is covered with a bag member 46 made of a slippery cloth having wear resistance as shown in FIG. Thereby, the rubbing roller 45 is prevented from being worn at an early stage due to the friction with the exterior ground 19.

  FIG. 13 shows a state where the second member 44 is attached to the first member 43 of the arm body 42, and FIG. 14 shows the first member 43 with the second member 44 removed.

  As shown in FIG. 14, a rectangular opening 47 is formed at the center of the first member 43 in the longitudinal direction. Concave portions 48 are respectively formed on both side portions and upper and lower portions of the opening 47. On the inner surface side of the first member 43, a slider 51 having guide pieces 49 on the upper and lower parts and both side parts respectively engages the guide pieces 49 with the recesses 48 so as to be slidable. Is retained.

  A fitting hole 52 is formed at the center of the slider 51. An eccentric cam portion 54 provided on the eccentric cam body 53 is rotatably inserted into the fitting hole 52. As shown in FIGS. 9 and 10, a pressing member 55 is screwed to the end surface of the eccentric cam portion 54 mounted in the fitting hole 52. Thereby, the eccentric cam body 53 is prevented from being detached from the fitting hole 52.

  As shown in FIGS. 10 and 14, an insertion hole 56 is formed in the eccentric cam body 53, and the roller shaft 33 is inserted into the insertion hole 56. The roller shaft 33 is connected by a key 57 so as to rotate integrally with the eccentric cam body 53.

  As shown in FIG. 10, the eccentric cam portion 54 is formed to be eccentric with respect to the axis of the roller shaft 33 and to be inclined at a predetermined angle.

  The pair of arm bodies 42 provided on the outside of the support body 31 are angled with respect to the eccentric cam body 53 attached to the roller shaft 33 by the restricting body 61 in the longitudinal direction, that is, both end portions swing vertically. Is now restricted.

  The restricting body 61 has a pair of restricting plates 62 provided on both sides of the eccentric cam body 53 as shown in FIG. The restricting plate 62 has a triangular shape as shown in FIG. 12, and the roller shaft 33 is rotatably inserted into an upper mounting hole 63 formed at the top thereof.

  Three lower mounting holes 64 are formed in a row on the lower side of the regulating plate 62. A sleeve 65 is provided between a pair of lower mounting holes 64 located at both ends of the lower side of the pair of restricting plates 62 facing each other with the eccentric cam body 53 interposed therebetween. The sleeve 65 is connected to the pair of restricting plates by a connecting screw 66. 62 is fixedly attached.

  As shown in FIGS. 8 and 9, on the outer surface of the lower end of the restriction plate 62 located on the support 31 side, a position corresponding to one sleeve 65 and a middle portion of the lower side of the restriction plate 62 are provided. A stopper 67 is fixed by screwing at a position of the lower mounting hole 64 to be performed.

  Each pair of stoppers 67 is provided so as to sandwich a locking portion 68 projecting from the lower ends of both side surfaces of the support 31. The stopper 67 and the locking portion 68 constitute stopper means.

  One of the pair of sleeves 65 in which the pair of restricting plates 62 are connected at a predetermined interval is shown in a connecting hole 69 formed in the lower portion of one end in the longitudinal direction of the arm body 42 as shown in FIGS. 9 is coupled so as to be able to swing in a 360-degree direction via a spherical bearing 70 shown in FIG.

  That is, the arm body 42 swings integrally with the regulating body 61 with respect to the eccentric cam body 53 attached to the roller shaft 33.

  Then, the swinging of the arm body 42 along the longitudinal direction is limited by a pair of stoppers 67 provided on the restriction plate 62 of the restriction body 61 coming into contact with the locking portions 68 provided on the support body 30. It is like that.

  Therefore, when the pair of squeezing rollers 45 provided on the arm body 42 are driven and driven by the roller unit 17 while massaging the back surface of the user U, The pair of stoppers 67 limit the large swinging of the arm body 42 in the vertical direction.

  On the other hand, when the roller shaft 33 is rotationally driven by the second drive source 35, the eccentric cam body 53 is interlocked with the rotation. An eccentric cam portion 54 of the eccentric cam body 53 is rotatably fitted in a fitting hole 52 of a slider 51 that is slidably held on the arm body 42. The eccentric cam portion 54 is eccentric with respect to the axis of the roller shaft 33 and is inclined at a predetermined angle.

  Therefore, when the eccentric cam body 53 rotates together with the roller shaft 33, the pair of arm bodies 42 are tilted in the vertical direction, and as shown in FIGS. Swing motion in the direction of alternating contact and separation. Thereby, the user U can receive a massage at night on the back of the body by the squeezing rollers 45 provided at one end and the other end in the longitudinal direction of the pair of arm bodies 42.

  Since the slider 51 slides along the longitudinal direction of the arm body 42 according to the rotation of the eccentric cam body 53, the arm body 42 swings without moving in the longitudinal direction. Yes.

  When a stop operation is performed to stop the rotation of the roller shaft 33 by the second drive source 35, the optical sensor 37 detects the detection member 36 provided at the end of the roller shaft 33 as described above. The roller shaft 33 is stopped after a predetermined pulse. Accordingly, the pair of arm bodies 42 are stopped in a parallel state as shown in FIG.

  The roller shaft 33 is provided with side massage parts 71 on the outside of the pair of massage massage parts 41. The said side massage part 71 is comprised as shown in FIG. 16 FIG. That is, the said side massage part 71 has a pair of disk 72 which spaced apart and paralleled at predetermined intervals. A center portion of the pair of disks 72 is connected by a hollow shaft 73. The roller shaft 33 is rotatably inserted into the hollow shaft 73.

  A one-way clutch 74 is provided at one axial end of the inner peripheral surface of the hollow shaft 73. As shown in FIGS. 18A and 18B, the one-way clutch 74 has recesses 75 formed on the inner peripheral surface of the hollow shaft 73 at a predetermined interval in the circumferential direction. One end portion of the concave portion 75 along the circumferential direction is formed on a tapered surface 76 that makes the concave portion 75 shallower than other portions. A clutch shaft 77 is urged toward the tapered surface 76 by a spring 78 in the recess 75.

  When the roller shaft 33 is rotationally driven in the counterclockwise direction indicated by an arrow A in FIG. 18A (this direction is the reverse direction), the clutch shaft 77 is urged by the urging force of the spring 78. The inside moves to the tapered surface 76 side. Accordingly, the clutch shaft 77 is pressed against the outer peripheral surface of the roller shaft 33, so that the hollow shaft 73 is coupled to the roller shaft 33. That is, the one-way clutch 74 is engaged.

  When the roller shaft 33 is rotated in the clockwise direction indicated by an arrow B in FIG. 18B (this direction is referred to as a normal rotation direction), the clutch shaft 77 is resisted against the biasing force of the spring 78. The concave portion 75 moves in a direction away from the tapered surface 76. As a result, the hollow shaft 73 does not rotate with respect to the rotation of the roller shaft 33. That is, the hollow shaft 73 rotates idly with respect to the roller shaft 33.

  As shown in FIG. 16, a plurality of support shafts 79 are supported around the pair of disks 72 so as to be rotatable at predetermined intervals in the circumferential direction. A barrel roller 81 and a drum roller 82 as side rollers are alternately attached to the plurality of spindles 79 in the circumferential direction.

  The top 81 a of the barrel roller 81 is located at the center between a pair of opposing disks 72, and the two tops 82 a of the drum roller 82 are shifted in the axial direction with respect to the top 81 a of the barrel roller 81. In position.

  Therefore, when the roller unit 17 is driven and driven along the guide rail 4 by the first drive source 9, the barrel-shaped roller 81 and the drum-shaped roller 82 are placed on the back surface of the user U, particularly the thigh. Massage the back of the leg, which is the shin part.

  At that time, the back surface of the leg portion is strongly massaged by a total of three top portions, one top portion 81a of the barrel roller 81 and two top portions 82a of the drum roller 82. Therefore, compared with the case where the back surface of a leg part is massaged only with a barrel-shaped roller like the past, the massage effect with respect to the leg part of the user U can be heightened.

  The barrel roller 81 and the drum roller 82 of the side massage portion 71 are covered with a bag member 84 formed of a slippery cloth as well as having wear resistance as shown in FIGS. . As a result, the barrel roller 81 and the drum roller 82 are prevented from being worn out early, and the exterior ground 19 is prevented from being damaged early.

  FIG. 21 shows a control system diagram. In the figure, reference numeral 86 denotes a control device. The controller 86 is provided in the main body 1 as shown in FIG. A remote controller and a controller 87 are connected to the controller 86 as an operation unit. Ream and controller 87 are also shown in FIG.

  Although not shown in detail in the reamor and controller 87, various massage patterns by the massage device M, such as the shoulder massage roller 15, the massage roller 45 of the massage massage part 41, and the barrel roller 81 of the side massage part 71, A massage pattern by the drum roller 82 can be set.

  The controller 86 controls the driving of the first drive source 9, the second drive source 35 and the heater 21 based on the operation signal from the remote control and the controller 87. A detection signal of the optical sensor 37 is output to the control device 86, and thereby, the rotation of the roller shaft 33 by the second drive source 35 is controlled to stop at a set angle. That is, the pair of arm bodies 42 of the massage massage part 41 are stopped at a position where they are parallel.

Next, a usage pattern of the massage device M configured as described above will be described.
If the user U lies on the upper surface of the massage apparatus M and the chest is held by the first and second holding members 24a and 24b as shown in FIG. Select.

  For example, when the roller unit 17 is run and the whole body is massaged, the massage can be received without operating the second drive source 35. In that case, since the pair of arm bodies 42 of the massaging massage portion 41 are stopped in a parallel state as shown in FIG. 15C, the massaging rollers 45 provided at both longitudinal ends of the pair of arm bodies 42 are used. Users can receive massage on both sides of the spine.

  At this time, the barrel-shaped roller 81 and the drum-shaped roller 82 of the side massage unit 71 rotate and massage the portion outside the massage portion by the kneading roller 45 on the back surface of the user U.

  Therefore, the user U can receive a massage over a wide area on the back surface, and can receive a strong massage at the leg portion by the two top portions 82 a of the barrel roller 81 and the drum roller 82.

  When the roller unit 17 is run and the whole body is massaged, the second drive source 35 is activated by operating the remote controller 87, and the roller shaft 33 is rotated in the clockwise direction indicated by the arrow B in FIG. Let

  As a result, the pair of arm bodies 42 of the massaging massage portion 41 are driven to swing in a direction in which one end and the other end in the longitudinal direction are alternately contacted and separated from each other. The massaging roller 45 provided at the end performs pressure massage while massaging both sides of the spinal column on the back of the user U.

  When the roller shaft 33 is rotated in the clockwise direction indicated by the arrow B in FIG. 18B, the side massage portion 71 is disengaged from the clutch shaft 77 of the one-way clutch 74 and the roller shaft 33. The hollow shaft 73 connecting the pair of disks 72 provided with the barrel-shaped roller 81 and the drum-shaped roller 82 of the side massage portion 71 is idly rotated.

  As a result, the side massage portion 71 travels without being driven to rotate by the roller shaft 33, so that the barrel roller 81 and the drum roller 82 provided on the disk 72 rotate with respect to the support shaft 79. The back of the user U, particularly the back of the leg, will be massaged strongly.

  When it is desired to receive a strong massage on the back of the leg by the side massager 71, the driving of the roller unit 17 by the first drive source 9 is stopped at a desired site by operating the remote controller 87. Then, the roller shaft 33 is rotated in the counterclockwise direction indicated by an arrow A in FIG.

  When the roller shaft 33 rotates in the direction of arrow A, the clutch shaft 77 of the one-way clutch 74 meshes with the roller shaft 33, so that the barrel roller 81 and the drum roller 82 are provided integrally with the roller shaft 33. The massage part 71 rotates.

  As a result, the user U can receive a massage by the plurality of barrel-shaped rollers 81 and the drum-shaped rollers 82 of the side massage part 71 rotating with the roller shaft 33 at a desired portion on the back. Compared with the case where the side massage part 71 is not forcibly rotated by the roller shaft 33, a stronger massage can be received.

  The side massage portion 71 may be forcibly rotated by the roller shaft 33 while the roller unit 17 is reciprocated in the longitudinal direction of the main body 1 by the first drive source 9. If it does so, the user U can receive a sufficiently strong massage by the massaging massage part 41 and the side massage part 71 over the whole body of the back.

  Moreover, the side massage portion 71 has the drum-shaped roller 82 having a V-shaped side surface, so that the leg portion of the user U is supported by the V-shaped portion of the drum-shaped roller 82 and is not easily displaced in the left-right direction. Become. That is, since the leg portion is difficult to come off from the barrel roller 81 and the drum roller 82 of the side massage portion 71, the massage effect on the leg portion can be improved as compared with a conventional chair type or mattress type massage device.

  When the user U is massaged by the massaging massage part 41 and the side massaging part 71, the shoulder massaging roller 15 of the shoulder massaging unit 14 can be selectively activated by operating the remote controller 87.

  Thus, when the user U receives a massage, the user U is hold | maintained by the 1st, 2nd holding members 24a and 24b. Therefore, even if the back surface of the user U is pressed by the massaging massage part 41 and the side massage part 71, the body rises on the upper surface of the massage apparatus M and the massage effect is reduced, or the movement of the roller unit 17 causes the vertical direction. Since it is prevented from moving to the side, the massage effect can be enhanced.

  The various massage patterns described above can be performed automatically or manually by operating the remote controller 87.

  The kneading roller 45 of the kneading massage part 41 and the barrel roller 81 and the drum roller 82 of the side massage part 71 are each covered with bag members 46 and 84 made of slippery cloth having wear resistance. ing.

  Therefore, the stagnation roller 45, barrel roller 81, and drum roller 82 are not only prevented from being quickly worn out by sliding contact with the inner surface of the exterior ground 19, but are also prevented from being damaged early. Is done.

  In the above embodiment, in order to rotate the pair of side roller portions integrally with the roller shaft, a one-way clutch is provided between the roller shaft and the hollow shaft of the side roller portion, and the rotation direction of the roller shaft is Accordingly, the side roller portion is driven to rotate integrally with the roller shaft. For example, the hollow shaft is attached to the roller shaft so as not to be rotatable by a key, and is engaged in the rotation direction of the roller shaft. Instead, the side roller portion may be driven to rotate integrally with the roller shaft.
