Description

  The present invention relates to a massage machine that includes treatment means for operating a treatment element such as a kneading ball and that can perform massage with the treatment element for a user.

  In a chair-type massage machine that performs massage while supporting the user's body, the massaging ball as a treatment element usually provided on the backrest part can be moved forward and backward with respect to the user leaning on the backrest part. The desired massage strength can be obtained. With such a massage machine, the mechanism for advancing and retracting the kneading balls is supported so that the kneading balls can be tilted together with the drive mechanism, and the driving mechanism is tilted by a predetermined tilting mechanism, so that the integral kneading balls can be tilted. In general, a mechanism has been used in which the kneading balls are moved in the front-rear direction of the user to obtain a situation in which the kneading balls are adjusted to advance or retreat with respect to the user. One example of a massage machine that employs such a kneading ball advance / retreat mechanism is disclosed in Japanese Patent Application Laid-Open No. 2007-6975.

JP 2007-6975 A

  The mechanism for advancing and retracting the kneading balls as a treatment element in a conventional massage machine with respect to the user is provided with a tooth part (rack) in the kneading ball unit as a tilting mechanism and meshed with this as shown in the patent document. Then, a gear (pinion gear) that transmits the driving force from the driving source is disposed, and the kneading balls and the driving unit thereof are tilted using these gear trains so that the kneading balls can be advanced and retracted. ing.

  In such a conventional mechanism, the drive mechanism part of the kneading balls is tilted back and forth to adjust the advance and retreat of the kneading ball position, so that sufficient space for the entire drive mechanism part to move during the adjustment is required in the front-rear direction of the backrest part. As a result, the mechanical unit of the kneading balls and the backrest part in which the mechanical unit moves inside cannot be made compact in the front-rear direction.

  In general, an electric motor is used as a drive source for the tilting mechanism for advancing and retreating, and these support the tilting mechanism in the immediate vicinity of the tilting mechanism from the relationship of driving force transmission, that is, the kneading ball driving mechanism part or the driving mechanism part is supported to be tiltable. Because it is placed on the member, the weight of the entire mechanism that moves the backrest up and down is increased, and the frame part of the massage machine, including the backrest that supports it, must have a certain level of strength, which increases the overall weight. It was.

  The present invention has been made to solve the above problems, and as a simple treatment element moving mechanism using air pressure, the treatment means and the size of the backrest portion in which the treatment means moves up and down while ensuring a sufficient movement range of the treatment element. The object is to provide a massage machine that can be made compact.

  The massage machine according to the disclosure of the present invention includes a seat portion and a backrest portion, and has a treatment means that is incorporated in the backrest portion and performs a predetermined massage on the user's body. The treatment means is a treatment element that gives a massage stimulus to the user, and a treatment that is arranged so as to be tiltable about a predetermined tilting axis, and the treatment element is attached to an end protruding outward with respect to the tilting axis position. A child support member and a drive mechanism unit that supports the treatment element support member in a tiltable manner, and tilts the treatment element support member to move the treatment element relative to a user during massage, the drive mechanism unit including the treatment device A link member that is at least tiltably connected to the treatment element support member at a predetermined position away from the tilt axis position of the child support member, and is arranged to be movable in conjunction with the treatment element support member; A treatment element moving air cell that moves the link member in accordance with expansion / contraction deformation due to supply / discharge of air, and the treatment element moving air cell is different from at least a backrest front-rear direction by expansion / contraction. The treatment element support member interlocked with the link member is tilted to change the position of the treatment element in the front-rear direction.

  As described above, according to the disclosure of the present invention, as a means for moving the treatment element in the back-and-forth direction of the backrest, a treatment element moving air cell that is inflated and contracted by air supply / exhaust is provided. By moving the link member in a direction different from the back-and-forth direction of the backrest part and tilting the treatment element support member via the link member, the treatment element at the end of the support member is moved forward and backward in the back-and-forth direction of the backrest part. In response to the massage performed by the treatment element and the position adjustment of the treatment element, the movement of the treatment element in the longitudinal direction of the backrest, that is, the movement of the treatment element to move back and forth with respect to the user's body is caused by the expansion and contraction of the air cell. Thus, it is not necessary to use a complicated mechanism including a motor and a speed reduction mechanism, and the drive mechanism can be simplified. Also, the movement associated with the expansion and contraction of the air cell for moving the treatment element is converted into the tilt of the treatment element support member using the link member, so that the amount of expansion and contraction deformation of the air cell and the movement amount of the treatment element can be changed. The degree of freedom of movement of the child can be increased, and the expansion / contraction space of the air cell corresponding to the amount of movement of the treatment element can be reduced as in the case where the expansion / contraction of the air cell is directly used for movement in the back and forth direction of the back of the treatment element There is no need to secure the backrest portion in the front-rear direction, the front-rear direction dimensions of the treatment means can be made compact, and the treatment means and the backrest portion incorporating the treatment means can be downsized together with the simplified minimum required mechanism configuration. The weight can be reduced, the cost of the massage machine as a whole can be reduced, and massage for the user can be performed more efficiently at a lower cost.

  Further, the massage machine according to the disclosure of the present invention includes at least a treatment element moving air cell that supports the treatment element support member so that the treatment element can be tilted with the treatment element exposed to the outside as necessary. A housing made of a material that does not deform even when subjected to a force accompanying expansion and contraction, wherein the treatment element moving air cell is disposed along a predetermined position on the outer surface of the housing, and is linked to the housing by deformation associated with expansion and contraction. Is moved, and the treatment element support member is tilted.

  Thus, according to the disclosure of the present invention, the treatment element support member is tiltably supported by the housing made of a material that is not easily deformed, while the treatment element moving air cell is disposed along the outer surface of the housing, and the treatment element is arranged. By moving the link member relative to the housing using the moving air cell and tilting the treatment element support member connected to the link member, the air cell expands and contracts from the housing as a starting point, and the link member expands and contracts. The movement corresponding to the contraction can be appropriately given, and the force associated with the expansion and contraction of the air cell can be transmitted without difficulty from the link member to the treatment element support member, so that the treatment element can be moved smoothly.

  Further, the massage machine according to the disclosure of the present invention includes a pressure receiving member that is provided outside the housing so as to be movable with respect to the housing, and is connected to an end of the link member. The housing is disposed between a predetermined position on the outer surface of the housing and the pressure receiving member, and the pressure receiving member is moved relative to the housing by deformation accompanying expansion and contraction, and the link member attached to the pressure receiving member is moved in the vertical direction of the backrest portion to support the treatment element. The member is tilted.

  Thus, according to the disclosure of the present invention, the treatment element moving air cell is disposed between the outer surface of the housing and the pressure receiving member, and the pressure receiving member is moved with respect to the housing using the treatment element moving air cell, By causing the link member to move up and down in the backrest part, the expansion and contraction of the air cell changes the distance between the housing and the pressure receiving member, and the expansion and contraction deformation of the air cell that occurs from the housing is reliably linked. It can be used by converting into movement of the member, and the treatment element can be moved smoothly without loss of force due to the pressure of the air cell. In addition, the space for moving the link member according to the expansion and contraction of the air cell can be set in the vertical direction of the backrest portion that is perpendicular to the longitudinal direction of the backrest portion where the treatment element is to be adjusted. The necessary space can be minimized, and the treatment means can be made more compact and the entire backrest can be made thinner.

  Further, in the massage machine according to the disclosure of the present invention, if necessary, the treatment element moving air cell is arranged in a plurality of stages on the outside of the housing, and the link member end portion is any of the overlapping multi-stage air cells. The treatment means can be moved with respect to the housing by the expansion / contraction of the treatment element, and the treatment means repeatedly expands / contracts the air cell for moving the treatment element of at least one stage, reciprocates the link member, and connects to the link member. By swinging the member, the treatment element is repeatedly moved back and forth in the back-and-forth direction of the backrest, and an operation of repeatedly hitting the user's massage target portion with the treatment element is executed.

  Thus, according to the disclosure of the present invention, when a treatment element moving air cell is arranged in a plurality of stages and the treatment element is moved in the front-rear direction of the backrest for position adjustment or the like, any of the treatment element moving air cells is used. The treatment element support member is tilted based on the expansion and contraction of the treatment element, causing a back and forth movement of the treatment element in the front-rear direction, while repeating a predetermined treatment element moving air cell particularly when trying to perform a tapping massage. By reciprocating the link member by expansion and contraction, the treatment element support member swings in conjunction with the movement of the link member and causes a repeated movement corresponding to the hitting of the treatment element. The simple movement related to the position adjustment in the back and forth direction of the backrest portion and the periodically repeated movement related to the tapping massage etc. can be appropriately performed simultaneously in correspondence with the expansion and contraction of the plurality of air cells. In addition, the massage strength required by the user can be obtained by adjusting the position of the treatment element in the back and forth direction of the back of the treatment element while performing the massage of tapping to move the treatment element back and forth in the direction of the back and back of the treatment part. It is possible to smoothly shift to a state that gives an optimal massage effect for the person, and the degree of relaxation of the user by the massage can be further increased.

  In addition, the massage machine according to the disclosure of the present invention includes an air supply / discharge unit that supplies and discharges air to and from the treatment element moving air cell, and a treatment element movement by controlling the operation of the air supply / discharge unit, as necessary. A control unit that changes the air supply / discharge state to the air cell and gives a predetermined expansion / contraction state of the treatment element moving air cell, the control unit is based on a setting given in advance or a user operation, The operating state of the air supply / discharge means is controlled and adjusted, and the treatment element is moved by expansion and contraction of the treatment element moving air cell accompanying the air supply / discharge, thereby adjusting the intensity of stimulation from the treatment element related to the massage.

  Thus, according to the disclosure of the present invention, the control unit controls the operation of the air supply / discharge means used for expansion / contraction of the treatment element moving air cell, and is controlled by the control unit based on the user's operation or the like. When the operating state related to the air supply / discharge of the discharge means changes, the expansion / contraction state of the treatment element moving air cell also changes, and the treatment element also moves via the link member or the treatment element support member. By changing the positional relationship with the user's body, the control unit changes the air supply / exhaust means according to the user's operation, etc., from the state where the massage with the treatment element is performed with the predetermined massage intensity. When the treatment element is given, the position of the treatment element is moved and adjusted, and the intensity of the stimulation to the user by the treatment element can be adjusted to the prescribed intensity. Individual differences in the user's physique and the user's posture Treatment on a massage machine, etc. If the control unit appropriately controls the air supply / exhaust means even in a situation where the desired massage strength for the user is not achieved in the initial state of receiving massage due to the difference in positional relationship between the user and the user's preference, The expansion and contraction state of the air cell for moving the treatment element is adjusted, the position of the treatment element is also adjusted, and the massage can be performed with the strength desired by the user, and the position of the treatment element is detected and grasped by a separate sensor etc. Even without performing special position adjustment control of such a treatment element, it is possible to reliably shift to a state where a massage that is appropriate and efficient for the user can be received.

However, a frame-like backrest frame 13a that supports each part of the backrest 13 from the inside, and a back air cell 73 and a waist air cell 74 that are expanded and contracted by the supply and discharge of air by the air pump 70 are provided. is there. Among these, the mechanical unit 50, the back air cell 73, and the waist air cell 74 respectively constitute treatment means for performing massage.

  In addition, a pair of side walls provided with treatment means such as air cells on the inner side facing the user are provided on the left and right sides of the backrest 13 so as to protrude from the user's upper arm. You can also make it possible to massage.

  The backrest frame 13a hangs a plurality of horizontal frames in a horizontal direction between a pair of left and right guide frames 13b that support the mechanical unit 50 in the vertical direction of the backrest 13 and restrain the movement in the other direction. It is handed over and connected together to form a substantially ladder-like frame structure.

  The mechanical unit 50 includes a pair of left and right kneading balls 51 as treatment elements that give the user stimulation related to massage such as massage and hitting, and right and left as treatment element support members that support the kneading balls 51 in a protruding state. Between the pair of kneading ball support arms 52 and the pair of left and right guide frames 13b, the backrest portion 13 is arranged so as to be movable in the vertical direction. The drive mechanism unit 60 generates movement related to movement, position adjustment, and the like corresponding to massage such as massage and hitting the ball 51.

  The kneading ball support arm 52 is supported by the drive mechanism 60 so as to be able to tilt around a predetermined tilting axis, and the kneading ball 51 is attached to one end protruding outward with respect to the tilting shaft position. A pair is arranged on the left and right with the center position in the left-right direction interposed therebetween.

  The drive mechanism 60 has a housing 61 supported on the side ends of the pair of guide frames 13b so as to be able to run up and down, and is disposed integrally with the housing 61, and the kneading balls 51 are controlled by the control unit 40. A stagnation motor 62 that generates a driving force for causing movement corresponding to stagnation, and an upper part of the housing 61 are disposed so as to be tiltable about an axis parallel to the central axis of tilting of the stagnation ball support arm 52. A first treatment member moving air cell is disposed between the pair of left and right first pressure receiving members 63, the housing 61 and the first pressure receiving member 63, and expands and contracts by air supply / discharge under the control of the control unit 40. One air cell 64 and a pair of left and right second air cells 66 as other treatment element moving air cells disposed on the upper side of the first pressure receiving member 63 and inflating and contracting by air supply and discharge based on the control of the control unit 40; 6 And a second pressure receiving member 65 attached to the upper side of the second air cells 66 and 67 and arranged to be movable with respect to the housing 61 and the first pressure receiving member 63, and one end thereof connected to the second pressure receiving member 65. The other end of the first air cell 64 and the second air cells 66 and 67 are connected to the kneading ball support arm 52 in a movable state in the vicinity of the housing 61. A pair of left and right link members 68 that transmit, and a housing mechanism 61, a squeezing mechanism (not shown) that transmits the driving force from the squeezing motor 62 to the squeezing ball support arm 52 to move the squeezing ball support arm 52 and the stagnation ball 51. ).

  As for the kneading motor 62 and the kneading mechanism, the kneading ball support arm 52 is continuously swung left and right or back and forth by rotational driving of the kneading motor 62 based on the control of the control unit 40, and the kneading balls 51 at the end of the arm. This is a mechanism similar to that used in a known massage machine that causes movement corresponding to the treatment of itchiness, and detailed description thereof is omitted.

  The housing 61 is formed of a hard substantially box-like body having a strength that does not deform even when subjected to a force accompanying expansion and contraction of each air cell, and the kneading ball support arm 52 is opposite to the one end where the kneading balls 51 are located. The other end portion is supported so as to be tiltable while surrounding the kneading ball support arm 52 as being exposed to the outside. A first air cell 64 is disposed along a predetermined position on the outer surface of the housing 61.

  The first pressure receiving member 63 is formed of a substantially plate-like body having a strength that does not deform even when subjected to the force accompanying expansion and contraction of each air cell, and can be tilted about an axis parallel to the tilting axis of the kneading ball support arm 52. Is attached to the upper part of the housing 61 and is movable with respect to the housing 61 outside the housing 61.

  The first air cell 64 is disposed between the outer surface of the housing 61 and the first pressure receiving member 63, is connected to the air pump 70 by a predetermined air supply / exhaust pipe, and is supplied by the air pump 70 based on the control of the control unit 40. The first pressure receiving member 63 is tilted with respect to the housing 61.

  The first air cell 64 has a structure in which expansion and contraction deformation is limited to a predetermined direction, and the first air cell 64 is expanded and contracted with respect to the housing 61 and the first pressure receiving member 63 attached to the housing 61 so as to be tiltable. By adopting a structure in which the first air cell 64 is disposed between the housing 61 and the first pressure receiving member 63 so as to be directed in the respective directions, the first pressure receiving member 63 is subjected to expansion / contraction deformation of the first air cell 64. It can be reliably converted to tilting.

  The second air cells 66 and 67 are arranged on the opposite side to the side where the first air cell 64 of the first pressure receiving member 63 is arranged as a pair of left and right, and are connected to the air pump 70 by a predetermined air supply / discharge line. The second pressure receiving member 65 which is expanded and contracted by supplying and discharging air by the air pump 70 based on the control of the control unit 40 and is provided so as to overlap with the first pressure receiving member 63 is moved away from or closer to the first pressure receiving member 63.

  The second pressure receiving member 65 is formed of a substantially plate-like body having a strength that does not deform even when subjected to a force accompanying expansion and contraction of the air cell, and is integrally attached to the outer surface of each of the second air cells 66 and 67. It connects with the edge part of 68.

  The second pressure receiving member 65 is attached to a substantially rod-shaped connecting member 65a that is common to the left and right second pressure receiving members 65, and the left and right second pressure receiving members 65 are connected to each other by the connecting member 65a. However, the left and right second pressure receiving members 65 can tilt with respect to the connecting member 65a.

  The second air cells 66, 67 and the second pressure receiving member 65 are respectively arranged on the left and right sides of the center position in the left-right direction of the backrest portion 13, and the second air cells 66, 67 are expanded and contracted with respect to the first pressure receiving member 63. By moving the pressure receiving member 65, the second pressure receiving member 65 can be moved with respect to the housing 61, and the link member 68 connected to each of the second pressure receiving members 66 and 67 can be moved in the vertical direction of the backrest portion with respect to the housing 61. .

  By providing the hard first pressure receiving member 63 between the two-tiered first air cell 64 and the second air cells 66 and 67, deformation caused by expansion or contraction of one air cell, as in the case where the air cells directly contact each other. However, the deformation of the other air cell is caused to be absorbed and the deformation of the entire air cell is not reduced, and the expansion / contraction deformation of each air cell can be reliably used for the movement of the second pressure receiving member 65 relative to the housing 61. The link member 68 connected to the second pressure receiving member 65 can be moved efficiently.

  The link member 68 is provided at a predetermined position on the other end away from the tilting axis position of the kneading ball support arm 52 in the front / rear / left / right directions corresponding to the movement of the kneading ball support arm 52 in each direction by the kneading mechanism. It is a substantially rod-like member that is connected using a joint portion 68a having a degree of freedom of tilting and is movably disposed in conjunction with the kneading ball support arm 52. The other end is connected to the second pressure receiving member 65. Is.

  Similarly to the kneading ball support arm 52, the link members 68 are arranged on the left and right sides of the center position in the left-right direction of the backrest portion, and the second pressure is received by the expansion / contraction deformation of the first air cell 64 or the second air cells 66, 67. The member 65 moves corresponding to each movement and tilts the kneading ball support arm 52 to be connected.

  The link member 68 and the second pressure receiving member 65 are connected in such a manner that the ends of the left and right link members 68 are attached to the left and right ends of the connecting member 65a that connects the left and right second pressure receiving members 65 to each other. In this way, the ends of the left and right link members 68 are also connected by the connecting member 65a, so that the movement of the second pressure receiving member 65 accompanying the expansion / contraction deformation of the second air cells 66, 67 is moderately restricted. Even when the expansion and contraction deformation directions of the two air cells 66 and 67 are not restricted and the air cell can be irregularly expanded and contracted, the second pressure receiving member 65 is not irregularly moved, and the expansion of the second air cells 66 and 67 is prevented. The contraction deformation can be reliably converted into the vertical movement of the back portion of the link member 68.

  The first air cell 64 and the second air cells 66 and 67 are disposed so as to overlap the outside of the housing 61, and a second pressure receiving member 65 is provided integrally with the outer second air cells 66 and 67, and this second pressure receiving member. Since the end of the link member 98 is connected to 65, the link member 68 can move relative to the housing 61 in conjunction with any expansion / contraction of the overlapping first air cell 64 and second air cells 66, 67. It is a mechanism to be done.

  Thus, each of the first and second air cells moves the second pressure receiving member 65 in accordance with expansion / contraction deformation caused by air supply / discharge, and the link member 68 connected to the second pressure receiving member 65 is moved in the vertical direction of the backrest portion. By moving the kneading balls, the kneading ball support arm 52 is tilted, and the position of the kneading balls 51 in the front-rear direction can be changed.

  When only the first air cell 64 is expanded and contracted as the mechanical unit 50, the first pressure receiving member 63 is tilted together with the second air cells 66 and 67 and the second pressure receiving member 65 on the outer side to move the end of the link member 68. Thus, the kneading balls 51 can be moved in the back-and-forth direction of the backrest part via the link member 68 and the kneading-ball support arm 52 (see FIG. 7). In addition to the movement related to the adjustment of the amount of protrusion in the advancing / retreating direction with respect to the user, it can be used for the movement of the kneading balls 51 that cause a relatively slow and weak application of pressure, for example, corresponding to a massage of acupressure.

  Further, when the left and right second air cells 66 and 67 are alternately expanded and contracted as the mechanical unit 50, the link member 68 is reciprocated in accordance with the repeated movement of the second pressure receiving member 65 accompanying the expansion and contraction deformation. Thus, the kneading ball support arm 52 connected to the link member 68 is swung, and the kneading balls 51 are repeatedly moved back and forth in the back-and-forth direction of the backrest (see FIG. 10). Can perform tapping action.

  When the kneading balls 51 are caused to repeatedly generate a movement corresponding to a massage of hitting or a movement corresponding to another kneading or the like, the back of the kneading balls 51 based on the expansion and contraction of the first air cell 64 in the front-rear direction. When the position adjustment is executed, the range of repeated movement of the kneading balls 51 changes, and the positional relationship between the kneading balls 51 and the user changes when the stimulus corresponding to hitting or kneading is applied. Thus, it is possible to adjust the strength of the stimulus applied to the user, that is, the strength such as itch or hit.

  A mechanism for tilting the kneading ball support arm 52 for the movement of the kneading balls 51 causes the first air cell 64 and the second air cells 66 and 67 to expand and contract with respect to the fixed housing 61 to move the link member 68. The kneading ball support arm 52 is tilted via the link member 68, and the link member 68 is interposed between the air cell and the kneading ball support arm 52 so that the air cell does not directly connect the air cell and the kneading ball support arm. With the mechanism that does not move the kneading ball support arm 52 directly, the direction of expansion and contraction of the air cell and the movement direction of the kneading ball 51 can be made different, and the kneading ball 51 that moves in the back-and-forth direction of the backrest portion can be made different. For example, if the expansion and contraction of the air cell is directed in the vertical direction of the backrest part, the amount of expansion and contraction deformation of the air cell is sufficiently secured to increase the movement displacement of the kneading balls, and the driving machine The part 60 can be made compact in the backrest longitudinal direction.

  The movement of the kneading balls 51 can be changed by setting the shape of the link member 68 and the connecting position with each part, such as the relationship between the expansion / contraction deformation of each air cell and the movement amount and movement speed of the kneading balls 51 based on the deformation. The degree of freedom can be increased, for example, massage can be performed by moving the kneading balls 51 more quickly than the expansion / contraction deformation of each air cell, or the kneading balls can be reciprocated with a stroke larger than the expansion / contraction deformation amount of the air cells. it can.

The position of the kneading balls 51 in the backrest 13 (the target site for massage with the kneading balls) can be changed up and down.

  The mechanical unit 50 including the driving mechanism 60 moves in the vertical direction of the backrest 13 under the control of the control unit 40 according to the set massage, and the vertical position of the kneading balls 51 is adjusted. The position of the backrest 13 of the kneading ball 51 in the front-rear direction is adjusted by the tilting of the kneading ball support arm 52 due to the expansion and contraction of the first air cell 64, and the kneading ball 51 is positioned at the massage target location. After the movement of the kneading balls 51 or in parallel with the movement of the kneading balls 51, the control unit 40 activates the kneading motor 62 of the drive mechanism 60 in the mechanical unit 50 according to the type of massage, The air cells 66 and 67 are expanded and contracted by air supply / discharge, and the kneading ball support arm 52 is caused to perform a movement corresponding to massage such as kneading and hitting set in the kneading balls 51.

  In addition, the air supply / discharge of each air cell including the first air cell 64 and the second air cells 66 and 67 is specifically made to circulate between the air pump 70 and the air cell by the electromagnetic valves 80a, ..., 80g, The air cell is contracted by operating the air pump 70 to send air into the air cell and switching between the air supply for expanding the air cell and the electromagnetic valves 80a, ..., 80g to discharge the air from the air cell to the outside. This is a combination with exhaust, and is performed in the same manner as a known air supply / exhaust mechanism for massage, and detailed description thereof is omitted.

  However, a plurality of air pumps are provided and the first air cell 64 and the second air cells 66 and 67 are expanded and contracted by an air pump different from other air cells, or a small air pump is provided in the vicinity of the air cell for each air cell. In contrast, the air supply and discharge can be individually expanded and contracted, so that air supply and discharge to the air cell can be executed more quickly, the responsiveness to control instructions is improved, and the expansion and contraction is accelerated. The quality of the stimulus imparting from the kneading balls 51 based on can be improved.

  The armrests 14 are disposed on both sides of the seat 12 and are formed to stably support the user's forearm even when the backrest 13 changes the reclining angle or the seat 12 tilts. It is a configuration. The armrest 14 may also be provided with an air cell that operates by supplying and discharging air by the air pump 70 so that the user's forearm can be massaged.

  The said leg support part 15 is located in the front side of the seat part 12, and is arrange | positioned so that inclination is possible centering | focusing on the vicinity of the front end of the seat part 12. FIG. The leg support 15 may be provided with treatment means such as a leg air cell that operates by supplying and discharging air by the air pump 70 and a roller that presses the leg while moving up and down.

  The operation unit 30 includes a number of switches and display units for receiving various operation inputs to the massage machine, is detachably installed on the stand 31 on the side of the massage machine 1, and transmits operation inputs related to massage to the control unit 40. To do. Note that the position of the stand 31 can be adjusted so that the position of the switch and the display unit of the operation unit 30 is the optimum position for the user.

  The control unit 40 adjusts the other movable parts of the treatment means and the massage machine to a state corresponding to the user based on the detection result obtained by executing the position detection of each part of the user's body in advance. Control for performing appropriate massage is performed on the treatment means and other movable parts based on the operation of the operation unit, treatment contents recorded and set in advance, and information on the detection result.

  The control unit 40 is a computer including a CPU, a memory, an input / output interface, and the like as its hardware configuration, and is a mechanism that causes the computer to operate as the control unit 40 by a program stored in the memory or the like. The computer constituting the control unit 40 may be a microcomputer in which a CPU, a memory, a ROM, and the like are integrally formed.

  The computer unit constituting the control unit 40 is disposed in a predetermined space inside the massage machine 1 such as directly under the seat 12 and is in a state where it can communicate with the operation unit 30, and various motors of the mechanical unit 50. , Seat 12, backrest 13, actuators for tilting leg support 15, air pump 70, electromagnetic valves 80 a,..., 80 g are electrically connected to each other to detect the position of each part of the user's body. The operation of these drive mechanisms is controlled by a control signal output based on a preset position detection program, and by a control signal output based on massage data set at the time of massage execution.

  In addition, the control unit 40 is also electrically connected to signal output means such as an encoder that outputs the displacement amount of the mechanical unit 50 and each actuator, and the state of the mechanical unit 50, the seat portion 12, the backrest portion 13, In addition, the operation control of the driving means such as the motor and the actuator is performed while grasping the state of the leg support 15 such as the inclination.

  The control unit 40 also controls the operation of the air pump 70 with respect to the first air cell 64 and the second air cells 66 and 67, thereby changing the internal pressure of each air cell, respectively. give.

  The tilted angular displacement of the kneading ball support arm 52 occurs with the expansion and contraction of the air cell, and the expansion and contraction of the air cell is based on the operating state of the air pump 70, that is, the degree of air supply from the air pump 70. 40, the relationship between the operating state of the air pump 70 and the kneading ball position change due to the tilting of the kneading ball support arm 52 is stored in advance, and the control unit 40 adjusts and controls the operation of the air pump 70 based on this relationship. For example, the control unit 40 can adjust the stimulus application state by the kneading balls 51 to an appropriate one only by controlling the air pump 70.

  And the control part 40 controls and adjusts the operating state of the air pump 70 based on the setting given beforehand or a user's operation, By the expansion / contraction of the 1st air cell 64 accompanying air supply / discharge, the kneading ball 51 Is appropriately moved in the back-and-forth direction of the backrest part to adjust the intensity of stimulation from the kneading balls 51 related to the massage.

  In addition, the control unit 40 controls the mechanical unit 50 to detect the position of each part of the user's body prior to the massage, like the known massage machine, and moves the mechanical unit 50 from the initial position in the backrest 13 to the guide frame 13b. In the process of moving the kneading balls 51 along the user, a change in pressure on the kneading balls 51 from the user leaning against the backrest 13 and a change in the inclination of the kneading balls 51 are sequentially acquired. Based on the information, the user's shoulder position, spine line, and waist position can also be detected.

  Next, the operating state of the mechanical unit of the massage machine according to the present embodiment will be described. As a premise, the massage machine 1 is turned on with the user sitting on the massage machine 1 and the back is leaned against the backrest 13, the massage machine 1 is activated, and the weight and body shape of the user Preparation operations before starting massage such as detection and reclining angle adjustment of the backrest portion 13 and the like are completed, and further, an instruction to execute a massage course and the like is input by the user, and the control unit 40 receives the massage balls for the user. It is assumed that the massage by 51 is about to be performed.

  In the case of treatment with the kneading balls 51, the control unit 40 operates the lifting motor 53 to move the entire mechanical unit 50 up and down with respect to the guide frame 13b according to the set treatment contents, and moves the kneading balls 51 up and down. Adjust the position.

  Along with this vertical movement, the control unit 40 moves the kneading balls 51 to the user side by a predetermined amount or an amount adjusted in accordance with an input instruction by the user as the position adjustment of the kneading balls 51 in the front-rear direction. Project to the opposite or away from the user. Specifically, the control unit 40 operates the air pump 70 that supplies air to the air cell and the electromagnetic valve that switches the air flow state to the air cell, and expands and contracts the first air cell 64, so that the first pressure receiving member 63. Is tilted, the second pressure receiving member 65 outside the first pressure receiving member 63 is moved, and the kneading ball support arm 52 is tilted via the link member 68 connected to the second pressure receiving member 65, so that the kneading balls 51 The position of the backrest portion in the front-rear direction is adjusted, and the massaging balls 51 are positioned at the massage target location.

  For example, when the massaging balls 51 are in the position farthest away from the user in the back-and-forth direction of the backrest, such as when treatment with the massaging balls is performed for the first time, the control unit 40 operates the air pump 70 or the like to activate the first air cell 64. Inflate, move the link member 68 upward, tilt the kneading ball support arm 52 to be connected, and cause the kneading ball 51 to approach the user side leaning against the backrest 13 (see FIG. 7B).

  When the control unit 40 acquires from the operating state of the air pump 70 that the kneading ball support arm 52 has been tilted by a predetermined angle corresponding to a preset position of the kneading ball 51, the control unit 40 stops the operation of the air pump and the like. The expansion or contraction of the air cell 64 is stopped, the tilting of the kneading ball support arm 52 is stopped, and the kneading ball 51 is held at an appropriate position.

  After this or in parallel with the movement of the kneading balls 51, the control unit 40 operates the kneading motor 62 and / or expands / contracts the second air cells 66, 67 according to the type of treatment, and kneads. The ball support arm 52 is swung to cause the kneading ball 51 to perform a movement corresponding to the massage, such as the set massage or hitting.

  For example, the left and right second air cells 66 and 67 are sequentially expanded and contracted, the outer second pressure receiving member 65 is tilted, and the left and right link members 68 are alternately moved up and down with respect to the housing 61 of the drive mechanism unit. Each kneading ball support arm 52 connected to the member 68 is swung to cause the kneading balls 51 to move according to the treatment of hitting.

  When the air cell is inflated, the control unit 40 circulates the air pump 70 and the air cell with the electromagnetic valves 80e, 80f, and 80g and operates the air pump 70 when the air cell is expanded. Inflate the air. Conversely, when the air cell is contracted, the control unit 40 switches the electromagnetic valves 80e, 80f, and 80g as exhaust gas so that air is discharged from the air cell to the outside. Such air supply and discharge is performed in the same manner for other air cells of the massage machine, but this is performed in the same manner as for a known air cell.

  Even when the user performs an operation related to adjusting the strength of the massage while causing the movement of the kneading balls 51 corresponding to massage or hitting as a massage, the control unit positions the back of the kneading balls 51 in the front-rear direction. Adjustments will be made. In this case, according to the adjustment operation of the user, the control unit 40 operates the air pump 70 and the like, expands or contracts the first air cell 64 to tilt the first pressure receiving member 63, and positions the second pressure receiving member 65. In other words, the link member 68 is moved up or down, and the kneading ball support arm 52 interlocked therewith is tilted to adjust the position of the kneading ball 51. Thereby, the movement range of the kneading balls can be changed so as to be moved closer to or away from the user in the front-rear direction of the backrest portion, and the intensity of the stimulation accompanying the movement of the kneading balls 51 can be changed.

  For example, when a user who feels that the stimulation is too weak is applied while giving stimulation related to massage such as massage, the control unit 40 moves the massage ball 51 in the front-rear direction of the backrest portion. Control to move in the direction approaching. Specifically, the first air cell 64 is expanded to tilt the first pressure receiving member 63 upward, the position of the second pressure receiving member 65 is changed, the link member 68 is raised, and the other end portion of the kneading ball support arm 52 faces upward. (See FIG. 7).

  By such tilting of the kneading ball support arm 52, the kneading balls 51 are shifted to the side closer to the user while performing the movement related to the massage. Thereby, the massage from the kneading balls 51 that perform the pressure related to the squeezing and tapping, that is, the user can more effectively apply the squeezing and tapping pressure stimulation to perform effective massage.

  On the other hand, when the user feels that the stimulus such as itching or hitting is too strong, the control unit 40 moves the kneading ball 51 away from the user in the back-and-forth direction of the backrest part. I do. Specifically, the first air cell 64 is contracted to tilt the first pressure receiving member 63 downward, the position of the second pressure receiving member 65 is changed, the link member 68 is lowered, and the other end of the kneading ball support arm 52 faces downward. It will be in the state to tilt to.

  By such tilting of the kneading ball support arm 52, the kneading balls 51 are in a state of being shifted further away from the user while performing the movement related to the massage. As a result, the stimulus from the kneading balls 51 that perform pressing related to itching and tapping, that is, the pressing stimulus of stagnation and tapping, is weakened, and the burden on the user's body is reduced.

  Thereafter, the control unit 40 continues the operation of the kneading motor 62 and the expansion and contraction of the second air cells 66 and 67, continues the rocking related to the kneading and hitting of the kneading balls 51, and preliminarily as a treatment time for the kneading and hitting. When the set predetermined time elapses, the massage motor 62, the air pump 70, etc. are stopped to finish the massage and hitting treatment.

  When the massage or hitting treatment is completed and the process proceeds to another massage or the like, the control unit 40 determines that the position of the kneading ball 51 is not suitable for the next treatment, and the first air cell 64 and the second air cells 66 and 67. The kneading balls 51 are contracted so that the kneading balls 51 move away from the user in the back-and-forth direction of the backrest, and the elevating motor 53 is operated to move the mechanical unit 50 up or down. It will be adjusted so that it will be in the right position.

  As described above, in the massage machine according to the present embodiment, as means for moving the kneading balls 51 in the back-and-forth direction of the backrest portion, the first and second air cells that are inflated and contracted by air supply and discharge are provided, and the expansion of these air cells is provided. Along with the contraction, the link member 68 is moved in a direction different from the longitudinal direction of the backrest portion, and the kneading ball support arm 52 is tilted via the link member 68 so that the kneading balls 51 at the end of the kneading ball support arm 52 are tilted. Is moved forward and backward in the back-and-forth direction of the backrest part, it is related to the massaging ball 51 movement for massage execution and massage strength adjustment in the kneading balls 51, the movement of the kneading balls 51 in the front-and-back direction of the backrest parts, that is, the user's The motion of moving the kneading balls 51 forward and backward with respect to the body is caused by the expansion and contraction of the air cell, and it is not necessary to use a complicated mechanism including a motor and a speed reduction mechanism. It can be simplified.

  Further, the movement associated with the expansion and contraction of the air cell is converted into the tilting of the kneading ball support arm 52 using the link member 68, so that the amount of deformation of the air cell and the movement amount of the kneading ball 51 can be changed. The degree of freedom of movement of the air cell 51 can be increased, and the expansion and contraction of the air cell corresponding to the amount of movement of the kneading ball 51 is used as in the case where the expansion and contraction of the air cell is directly used for the movement of the kneading ball 51 in the front-rear direction. It is not necessary to secure a space in the front-rear direction of the backrest part, and the dimensions in the front-rear direction of the mechanical unit 50 can be made compact. The mechanical unit 50 and the backrest part in which the mechanical unit 50 is built-in are combined with the simplified minimum necessary mechanism configuration. 13 can be reduced in size and weight, the cost of the massage machine as a whole can be reduced, and massage for the user can be efficiently performed at lower cost.

  In the massage machine according to the embodiment, a pressure receiving member having a strength that does not deform even when subjected to a force accompanying expansion and contraction of each air cell is provided to be movable with respect to the housing 61, and the pressure receiving member is moved by each air cell. However, the present invention is not limited to this, and the portion of the outer surface of the air cell that moves due to expansion / contraction is made rigid, or a plate-like member that is difficult to deform is integrated into this portion. In this case, the end of the link member is attached to a portion that moves due to expansion and contraction, and the link member can be directly moved by the air cell. Also, instead of interposing the first pressure receiving member between the air cells arranged in two layers, the part facing each other air cell on the outer surface of each air cell is made hard as above, or a plate-like member that is not easily deformed is integrated. In addition, the air cells can be directly overlapped with each other, and, as in the above-described embodiment, the deformation due to the expansion and contraction of one air cell is absorbed by the deformation of the other air cell so that the deformation amount of the entire air cell is reduced. Without causing a serious situation, the expansion / contraction deformation of each air cell can be reliably used for the movement of the link member 68.

(Second embodiment of the present invention)
In the massage machine according to the first embodiment, the first air cell 64 and the second air cell 66, 67 are arranged in two stages, and the expansion / contraction state is controlled for each air cell. The movement of the kneading ball 51 related to the massage of hitting is generated at 67 and the second air cell position can be changed by the first air cell 64 to cause the right and left tilting of the kneading ball support arm 52 to be integrated. The range in which the kneading balls move can be adjusted in the front-rear direction of the backrest and the intensity of the stimulus can be adjusted. However, the present invention is not limited to this, and as shown in FIGS. Only one air cell 64a, 64b that causes the back of the ball to move back and forth is provided for each pair of left and right kneading ball support arms 52. These air cells 64a, 64b The structure which combines the role of the first air cell and the second air cell in the first embodiment, and causes the repeated movement of the kneading balls 51 related to the tapping massage and the kneading ball movement related to the adjustment of the stimulation intensity. It can also be.

  In this case, similarly to the kneading ball support arm 52, the air cells 64a and 64b provided as a pair of left and right arrangements expand and contract independently from each other by receiving and supplying air by the air pump 70 and the like based on the control of the control unit 40. . By the expansion and contraction of these air cells, as in the first embodiment, the right and left massaging ball support arms 52 are tilted by moving the link member 68, and the massaging balls 51 at the ends of the massaging ball support arms 52 are moved back and forth. It will be moved.

  For example, when the kneading ball performs the movement related to the massage of the hitting, the left and right air cells 64a and 64b are sequentially expanded and contracted, and the outer pressure receiving members 65b and 65c are tilted to the left and right with respect to the housing 61 of the drive mechanism section. The link members 68 are alternately moved up and down, and the kneading balls supporting arms 52 connected to the link members 68 are respectively swung to cause the kneading balls 51 to perform a movement related to the massage (see FIG. 12).

  When adjusting the position by moving the kneading balls to adjust the intensity of stimulation related to the massage applied to the user, at the same time, if it does not cause repeated movement of the kneading balls related to the massage, Similarly, the air can be expanded and contracted by supplying and discharging, and the kneading ball support arm 52 can be tilted equally to adjust the position of moving the left and right kneading balls 51 equally in either direction of the backrest front-rear direction. As in the previous embodiment, when the kneading balls 51 are moved forward to make the positional relationship between the kneading balls 51 and the user closer, stimulation related to the massage becomes stronger, and the kneading balls 51 are moved backward to use the kneading balls 51. When the positional relationship with the person is further distant, stimulation related to massage is weakened.

  In addition, when the kneading balls 51 are subjected to repeated movements related to massage such as massaging and hitting, the kneading balls 51 are caused to perform movements related to the massage. Thus, while the left and right air cells are in a predetermined periodic expansion / contraction state, the control unit 40 adjusts the expansion / contraction amount of each air cell so that the kneading ball support arm 52 is a backrest portion from each position during tilting related to the massage. In the same manner as described above, the relative tilting is performed in the same direction in the front-rear direction by the same predetermined displacement (see FIG. 13), and the range of movement in the movement related to the massage of the left and right kneading balls 51 is shifted in the front-rear direction of the backrest part. The intensity of the stimulus can be adjusted.

  In the massage machine according to each of the above embodiments, each air cell for moving the kneading ball support arm 52 by moving the link member 68 adjusts the position of the kneading ball 51 in the back-and-forth direction for adjusting the stimulation intensity, Although it is configured to be provided for the purpose of causing the massaging ball 51 to move related to the massage, the present invention is not limited to this, and an air cell is provided only for adjusting the position of the massaging ball in the back-and-forth direction of the backrest for adjusting the stimulation intensity. The repeated movement of the kneading balls in the back-and-forth direction of the kneading balls related to the massage may be generated by a mechanism using a motor as a drive source as in the conventional case.

(Third embodiment of the present invention)
In the massage machine according to each of the first and second embodiments, the pressure receiving member that moves with respect to the housing 61 of the drive mechanism 60 in response to the force from the air cell is disposed so as to be tiltable with respect to the housing 61. However, the present invention is not limited to this, and if the pressure receiving member is movable with respect to the housing 61, other arrangement forms, for example, the pressure receiving member can be moved linearly with respect to a predetermined portion of the housing 61 so as to be close to and separated from each other. It can also be set as the structure to arrange | position.

  In particular, as a third embodiment, as shown in FIGS. 14 and 15, a pressure receiving member 65d is arranged to be movable up and down with respect to the upper portion of the housing 61, and an air cell provided between the housing 61 and the pressure receiving member 65d is provided. By expanding and contracting, the link member 69 can be efficiently moved in the vertical direction of the backrest portion to smoothly tilt the kneading ball support arm 52, and the expansion and contraction of the air cell can be caused only in the vertical direction. It is not necessary to provide any space for shrinkage in the longitudinal direction of the backrest part, the size of the mechanical unit 50 in the longitudinal direction of the backrest part can be set to the minimum necessary, and the backrest part incorporating the mechanical unit 50 can also be reduced in size and weight. .

  In this case, the first air cell 64c and the second air cells 66a and 67a provided as a pair of left and right arrangements on the first air cell 64c are expanded and contracted by receiving and supplying air by the air pump 70 based on the control of the control unit 40, respectively. . By the expansion and contraction of these air cells, as in the first embodiment, the right and left massaging ball support arms 52 are tilted by moving the link member 69, and the massaging balls 51 at the ends of the massaging ball support arms 52 are moved back and forth. It will be moved.

  In adjusting the position of the kneading balls 51 in the front-rear direction, the control unit 40 operates the air pump 70 and the electromagnetic valve to expand and contract the first air cell 64c and move the upper pressure receiving member 65d. The kneading ball support arm 52 tilts via the link member 69 connected to the moving pressure receiving member 65d, and the kneading ball 51 is arranged at a predetermined position in the front-rear direction of the backrest (see FIG. 14).

  Along with such position adjustment, the control unit 40 operates the kneading motor 62 and / or expands / contracts the second air cells 66a and 67a according to the type of massage, and repeatedly tilts the kneading ball support arm 52 to set. The kneading balls 51 are caused to perform movements corresponding to massages such as massage and hitting.

  For example, when making the kneading ball perform the movement related to the massage of the hit, the left and right second air cells 66a and 67a are sequentially expanded and contracted, and the upper pressure receiving member 65d is moved so that the left and right heights thereof are different, The left and right link members 69 are alternately moved up and down relative to the housing 61. Thereby, each kneading ball support arm 52 connected to the link member 69 can be swung, and the kneading ball 51 can be caused to move according to the massage of the hit (see FIG. 15).
