Thereby, the reliability or safety of the medical treatment operation and tilting operation of the drive mechanism part 60 and the treatment elements can be enhanced, it is not necessary to make the tilting mechanism have a high-strength, and the tilting mechanism can be simplified to reduce the size of the whole mechanism part related to the treatment elements.

Description

  The present invention relates to a massage machine that can adjust the amount of protrusion of a treatment element such as a kneading ball toward a user, and more particularly to a structure that supports the treatment element and its drive mechanism.

  In a chair-type massage machine that performs a massage operation while supporting the body of the user, 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 treatment strength desired by the user 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 repositioned 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 Laid-Open No. 2002-159549.

  The mechanism for advancing and retracting the kneading balls as the treatment elements in the conventional massage machine with respect to the user is provided with a rack-like partial gear in the drive mechanism portion as a tilting mechanism and meshed with this to drive force from the drive source The pinion gears that transmit the movement are disposed, and the gear train and the drive mechanism portion thereof are tilted using these gear trains so that the kneading balls can be advanced and retracted.

JP 2002-159549 A

  The mechanism for advancing and retreating the kneading balls as the treatment elements in the conventional massage machine is configured as shown in the above-mentioned patent document, but such a tilting mechanism and a mechanism portion such as a kneading ball drive mechanism Therefore, there is a demand for further reduction in size and weight due to demands for weight reduction and cost reduction of the entire massage machine.

  In the case of the tilting mechanism of the partial gear and the pinion gear that drives the same as in the above-mentioned patent document, the partial gear and the pinion gear are arranged at the outermost part farthest from the tilting center position of the driving mechanism, and the pinion gear is located above the driving mechanism. The tilting mechanism greatly affects the size of the arrangement space of the entire mechanism portion. Therefore, the structure of the tilting mechanism is simplified and the space is saved by eliminating the need to support the pinion gear as a cantilever with a large rotation shaft and supporting the partial gear and pinion gear as close to the tilting center position as possible. At the same time, it is conceivable to reduce the size by increasing the degree of freedom of the configuration of the entire mechanism.

  On the other hand, in the said patent document, the arm part which supports a kneading ball with a drive mechanism part is pivotally supported near the center of the drive mechanism part which tilts. When using the massage machine, the massaging balls are in a state where a backward pressing force is relatively applied from the back of the user leaning on the backrest, and this pressing force is transmitted to the drive mechanism via the arm, Since the pivotal support position of the arm part is near the center of the drive mechanism part, the component of the force that causes the drive mechanism part to move backward in the pressing force is the same as the tilting central axis of the drive mechanism part. In addition, it is dispersed and added to the partial gear and the pinion gear that form the tilting mechanism.

  For this reason, the load applied to the pinion gear is relatively large. If the pinion gear is cantilevered, the mechanism may be damaged due to insufficient strength. As described above, it is difficult to make the pinion gear cantilevered with the conventional structure of the drive mechanism, and it is not easy to downsize or simplify the entire mechanism by reviewing only the tilt mechanism. It had the problem that.

  In addition, in the case of the tilting mechanism of the partial gear and the pinion gear as in the above-mentioned patent document, the partial gear and the pinion gear are arranged on the outermost part farthest from the tilting center position of the drive mechanism unit, and the tilt angle range of the drive mechanism unit If the circumferential length of the partial gear that regulates the length of the partial gear is increased, the partial gear will come into contact with each part in the backrest when the drive mechanism is tilted. It must be limited to a short length, and the tilt angle range of the drive mechanism portion could not be made very large. For this reason, the advancing and retreating range of the kneading balls based on the tilt angle range of the drive mechanism section is also limited, and the amount of kneading balls protruding to the user side cannot be increased. It had the subject that it was limited to the massage of the back body part facing.

  The present invention has been made to solve the above-mentioned problems. The support center position of the support portion of the treatment element in the backrest portion is made to coincide with the tilt center of the drive mechanism portion of the treatment element, and the force applied to the treatment element is easily received. In addition to ensuring the reliability and safety of the treatment operation, the tilting mechanism of the drive mechanism can be simplified, and the amount of protrusion of the treatment element can be easily secured, enabling more effective massage with the treatment element. The purpose is to provide a massage machine.

  The massage machine according to the present invention has an elevating mechanism that allows the treatment element disposed in the backrest part to move in the vertical direction of the backrest part together with the drive mechanism part of the treatment element, and the treatment element and the drive for the backrest part. In a massage machine having a tilting mechanism that allows the mechanism portion to tilt around a predetermined tilting axis to adjust the amount of protrusion of the treatment element toward the user, the tilting shaft is attached to one end of the treatment element. The treatment element support arm is supported at least in a swingable manner, and forms a part of the drive mechanism.

  As described above, according to the present invention, the drive mechanism portion of the treatment element is disposed in the backrest portion so as to be tiltable, while the treatment element support arm to which the treatment element in the drive mechanism portion is attached is supported by the tilting shaft. By allowing the force applied to the child to be transmitted to the tilting shaft as it is via the treatment element support arm, unnecessary force is not applied to the tilting mechanism of the drive mechanism, and when the tilting operation and tilting of the treatment element and the drive mechanism are stopped In addition to improving the reliability and safety of the treatment operation, there is no need to make the tilting mechanism of the drive mechanism part strong, and this tilting mechanism can be simplified and the entire mechanism part related to the treatment element can be downsized. Can be planned.

  Further, the treatment element support arm is supported by the tilting shaft so as to be swingable, so that the treatment mechanism for moving the treatment element by the drive mechanism section, for example, the operation such as staking and hitting, is accompanied by the swinging of the treatment element support arm. The movement of the treatment element that protrudes toward the user and the movement component that moves away from the treatment person substantially match the movement of the treatment element with the tilt of the entire drive mechanism by the tilt mechanism and the direction of the movement. Therefore, by appropriately linking and controlling the treatment operation and the tilting operation by the tilting mechanism, the movement of the treatment element protruding to the user side in the treatment operation can be freely adjusted, and the treatment variation by the treatment element can be expanded. A more varied massage effect can be imparted.

For example, when the treatment operation is a so-called itch operation that causes the treatment element to perform a movement having at least two components in the projecting direction and the width direction with respect to the user in the drive mechanism unit, and stimulates the user. The amount of protrusion of the treatment element with respect to the user in the itch operation is adjusted by executing the movement of the treatment element that protrudes to the user side generated by the drive mechanism unit and the tilting action by the tilt mechanism during the itch operation. In particular, it is possible to cancel only the component of the movement that protrudes toward the user side of the massaging operation of the treatment element by the drive mechanism part by the same degree of tilting operation in the reverse direction by the tilting mechanism, and thus the user The treatment element can be made to perform a movement like a so-called “suri” that does not apply a pressing force to the body. Furthermore, in the case where the treatment operation is a so-called hitting operation that gives the stimulus to the treatment element mainly by moving the treatment element in the protruding direction, the treatment element generated by the drive mechanism unit during this hitting operation The amount of protrusion of the treatment element with respect to the user in the tapping operation, that is, the stroke of the tapping can be freely adjusted by executing the movement of the protruding portion toward the user and the tilting operation by the tilting mechanism together. In addition, it is possible to adjust the strength of striking, for example, by increasing or decreasing the pressing force applied to the user from the treatment element by the movement of the treatment element in the protruding direction by the drive mechanism, by simultaneously executing the tilting operation by the tilting mechanism. Thus, the simple treatment as described above can be realized easily and without complicated feelings for the user.

  The massage machine according to the present invention is configured so that the treatment element support arm has a length from a portion supported by the tilting shaft to the treatment element attachment position, and at least the treatment element and the drive mechanism unit are treated. The treatment element can protrude beyond the position of the back side of the user when the user leans against the backrest and the position closest to the user in the drive mechanism with the patient tilted to the maximum. It is formed as a dimension.

  Thus, according to the present invention, the treatment element support arm is made sufficiently long so that the maximum protrusion amount of the kneading balls tilting with the drive mechanism section exceeds the back position of the user who leans against the backrest. Thus, the treatment element in the protruding state can approach the user from above the shoulder or from the lower back of the shoulder, detect each position of the body of the user using the treatment element, and massage with the treatment element Can be executed more efficiently, the massage position by the treatment element can be set appropriately, and a variety of massage effects can be provided from the treatment element.

  In addition, the massage machine according to the present invention includes a control unit that controls the tilting and vertical movement of the drive mechanism unit as necessary, and the control unit tilts the drive mechanism unit so that the user side of the treatment element The amount of protrusion to the back of the back of the user who was leaned against the backrest was larger, and the treatment element was lowered with the drive mechanism from above the shoulder of the treatment person, and the treatment element reached the upper shoulder The condition is detected and the shoulder position of the user is recognized.

  As described above, according to the present invention, the drive mechanism unit is tilted based on the control of the control unit, and the protruded treatment element is brought closer to the shoulder from above the shoulder of the user, and the treatment element reaches the shoulder upper side. The shoulder position can be set without the user's designation by obtaining the shoulder position from the user, and it is possible to save the operation and greatly improve the convenience of use. At the same time, the shoulder position is more accurate than the position detection only from the back side. Can be recognized, and the positional relationship of the body of the user can be accurately grasped on the control unit side, and the massage corresponding to each position of the body with the treatment element can be reliably executed.

  In addition, the massage machine according to the present invention includes a control unit that controls the tilting and vertical movement of the drive mechanism unit as necessary, and the control unit tilts the drive mechanism unit so that the user side of the treatment element The amount of protrusion to be larger than the back position of the user leaning on the backrest, lower the treatment element from above the shoulder of the user together with the drive mechanism, and allow the treatment element to reach the upper shoulder Thus, a massage operation is performed on the upper shoulder portion of the treatment element.

As described above, according to the present invention, the drive mechanism unit is tilted based on the control of the control unit, and the treatment element projecting larger than the back position of the user is brought closer to the shoulder from above the shoulder of the user, By massaging the massager with the massager on the upper side, massage of the user's shoulders such as itchiness and tapping with the treatmentr is performed not only from the back side but also from the upper side of the shoulder. An effect can be given and the treatment effect by massage to a shoulder can be heightened.

  In addition, the massage machine according to the present invention includes a control unit that controls the tilting and vertical movement of the drive mechanism unit as necessary, and the control unit tilts the drive mechanism unit so that the user side of the treatment element The amount of protrusion to the back of the user who is leaning against the backrest is larger than the back position of the user, and the treatment element is raised together with the drive mechanism from below the user's waist to reach the lower back of the treatment element. Thus, a massage operation is performed on the lower waist portion of the treatment element.

  As described above, according to the present invention, the drive mechanism unit is tilted based on the control of the control unit, and the treatment element that protrudes larger than the back position of the user is brought closer to the waist from below the waist of the user, By massaging the massager with the massager on the lower side, massages such as itchiness and tapping with the treatment element on the patient's lower back are performed not only from the back side but also from the lower side of the waist The massage effect on the waist can be enhanced.

  Further, according to need, the massage machine according to the present invention has a base portion that pivotally supports the tilt shaft and supports the drive mechanism portion so that the drive mechanism portion can tilt, and a gear center coincides with the tilt shaft. A partial gear fixedly disposed on a side portion of the drive mechanism portion and a pivotable portion disposed on the base portion, protruding in a cantilevered state from the base portion side to the drive mechanism portion side to the partial gear. A pinion gear that meshes and is rotationally driven by a predetermined drive source to move a partial gear, and the tilting mechanism is formed by the partial gear and the pinion gear.

  As described above, according to the present invention, the drive mechanism is supported by the base so as to be tiltable about the tilting shaft, while the partial gear fixedly provided on the drive mechanism and the pinion gear provided on the base are provided. The tilting mechanism of the treatment element and the drive mechanism part is configured, and the pinion gear protruding in a cantilevered support state from the base part side to the position where it engages with the partial gear is rotated to drive the partial gear and the drive mechanism part integral therewith. By tilting with respect to the base part, the force applied to the massaging balls from the user side is supported by the tilting shaft, and no force is applied to the pinion gear, and even if the pinion gear is supported as a cantilever, it can be operated without problems. The mechanism can be simplified and made compact. Further, it is not necessary to consider the contact between the pinion gear arranged in a cantilevered state and each part of the drive mechanism other than the partial gear, and the partial gear and the pinion gear can be arranged at a position close to the tilting shaft, Compared to the case where the tilt mechanism of the drive mechanism is arranged at the outer peripheral side of the drive mechanism with respect to the center axis of tilt, the entire drive mechanism including the tilt mechanism can be downsized and the surroundings can be affected. It is possible to easily secure the length of the partial gear without increasing the amount of protrusion, and to increase the amount of protrusion of the kneading ball, and to make the partial gear sufficiently long, the kneading ball that tilts with the change in the meshing state of the pinion gear and the partial gear. If the maximum amount of protrusion exceeds the back position of the user leaning against the backrest, the protruding treatment element is brought close to the user from above the shoulder of the user or below the waist, Each position of the user's body An outgoing and massages can be efficiently executed.

  In addition, the massage machine according to the present invention is disposed in the backrest portion and a base portion that pivotally supports the tilt shaft and supports the drive mechanism portion in a tiltable manner, if necessary. Centering on a plurality of guide frames that allow the base portion to move in the vertical direction of the backrest portion and restrain and support the movement in the other direction, and a central axis orthogonal to the direction of movement of the base portion in the vertical direction of the backrest portion A rotating body that is disposed at an end portion of the base portion so as to be rotatable, is driven to rotate by a predetermined drive source, travels up and down the guide frame, and moves the base portion relative to the guide frame; The guide frame and the rotating body constitute the lifting mechanism, the drive mechanism portion is mounted and disposed so as to be rotatable relative to the tilting shaft, and the tilting shaft also serves as the central axis of the rotating body. Ah .

As described above, according to the present invention, the tilting shaft, which is the center of tilting of the drive mechanism portion, can be rotated with respect to the drive mechanism portion while supporting the drive mechanism portion, and travels on the guide frame. The tilting shaft is provided with a plurality of functions by providing a state in which the driving mechanism and the base are supported so as to be movable up and down with respect to the guide frame while also serving as the central axis of the rotating body that moves up and down integrally with the driving mechanism. As a whole, a simple elevating mechanism can be realized, and it is not necessary to separately arrange the tilting axis that becomes the center of tilting of the drive mechanism part and the center axis of the rotating body for vertical movement, increasing the space usage efficiency in the base part Thus, it is possible to reduce the size of the vertically moving portion composed of the drive mechanism portion and the base portion, and the cost of the lifting mechanism and the tilting mechanism can be reduced.

  Further, in the massage machine according to the present invention, if necessary, the guide frame is formed in a substantially U-shaped cross-sectional shape, and a rack is disposed on an inner peripheral portion, and the rotating body is tilted. A pinion gear portion that is attached to an end portion of the shaft and at least a part of which engages with a rack of the guide frame, is attached to the base portion so as to be rotatable about an axis parallel to the tilting shaft, and the rotating body is The guide frame includes a roller that is in rolling contact with an outer peripheral surface of the guide frame in a state of meshing with the rack and that can move up and down together with the base portion and the rotating body with respect to the guide frame.

By maintaining the relationship and securely meshing without separation, the rotating body can always maintain meshing with the rack and can move up and down reliably with respect to the guide frame. The massager can be accurately massaged at the position, and the presence of the roller can maintain the meshing state of the rotating body and rack regardless of the shape accuracy of the guide frame over the range in which the base part can be moved up and down. There is no need to secure the rigidity to form and maintain the shape strictly against external force, and the structure of the guide frame can be simplified and reduced in weight to reduce costs. .

Control unit 4 A configuration including and.

  The base 11 is configured to integrally support the seat 12, the backrest 13, the armrest 14, and the leg support 15 that constitute each part of the chair. The seat portion 12 is attached to the base portion 11 so that the inclination angle of the seat surface can be adjusted, and performs massage with a built-in treatment mechanism while supporting the user's buttocks on the seat surface. As the treatment mechanism, the heel part air cell 71 and the thigh air cell 72 that operate by supplying and discharging air are provided. An air pump 70 that operates these air cells by supplying and discharging air is disposed in a space below the seat portion 12.

The backrest part 13 is arranged so that the inclination angle can be adjusted with respect to the base part 11 and the seat part 12, and the mechanical unit 50 is provided therein, while the mechanical unit 50 is also provided with the backrest part 13. A pair of left and right guide frames 20 that are movable in the vertical direction and restrained to support movement in other directions, a back air cell 73 and a waist air cell 74 that are operated by supplying and discharging air by the air pump 70, and the interior of the backrest portion And a frame 17 that is arranged above and below and forms a frame shape with the guide frame 20 to maintain the shape of the backrest portion. Among these, the mechanical unit 50, the back air cell 73, and the waist air cell 74 are massaged, respectively. The treatment mechanism to execute. In addition, a pair of side wall portions provided with a treatment mechanism such as an air cell on the inner surface facing the user is provided on both the left and right sides of the backrest portion 13 so as to protrude from the upper arm of the user. You can also make it possible to massage from the side.

  The guide frame 20 has a substantially U-shaped cross-sectional shape and is formed in a longitudinal shape along the surface of the backrest portion 13 in accordance with the shape of a human back, and a pair is disposed on the left and right inside the backrest portion. This is a configuration. The mechanical unit 50 is disposed so as to be movable along the guide frame 20 so as to be sandwiched between the two guide frames 20 forming a pair. A resin rack 21 is disposed on the inner periphery of the guide frame 20 as a length that extends over the vertical movement range of the mechanical unit 50. By arranging the rack 21 on the inner peripheral side of the guide frame 20, a sufficient lateral width can be secured while avoiding physical interference with each part of the mechanical unit 50.

  The mechanical unit 50 includes a pair of left and right kneading balls 51 as a treatment element that gives the user a stimulus such as hitting and hitting the backrest portion 13 and the treatment element support arm that supports the kneading balls 51 in a protruding state. A pair of left and right kneading ball support arms 52, a drive mechanism 60 that drives the kneading balls 51 in response to massage operations such as striking and hitting the kneading balls 51 via the kneading ball support arms 52, and a backrest portion that is perpendicular to the vertical direction. And a tilting shaft 53 that supports the drive mechanism 60 so as to be relatively rotatable, a base portion 54 that pivotally supports the tilting shaft 53 and supports the drive mechanism 60 so as to be tiltable, and tilts. It is arranged at the end of the base part 54 so as to be rotatable about a shaft 53, and is driven to rotate up and down by an elevating motor 57 as a drive source, so that the guide part 20 travels up and down. A rotating body 55 that is moved with respect to 0, and a roller 56 made of an elastic material that is attached to the side of the base portion 54 so as to be rotatable around an axis parallel to the tilting shaft 53 and that is in rolling contact with the outer peripheral surface of the guide frame 20 It is the structure provided with. The base portion 54, the rotating body 55, and the guide frame 20 in the mechanical unit 50 form the lifting mechanism.

  The drive mechanism 60 is disposed to be supported by the tilting shaft 53 so as to be rotatable relative to the tilting shaft 53, and can be tilted about the tilting shaft 53. And a housing motor 62 provided in the housing 61 for applying a driving force for causing the kneading balls 51 to perform a kneading operation, and also provided in the housing 61 for striking the kneading balls 51. A tapping motor 64 that gives a driving force to perform, a kneading motor 62 in the housing 61, a kneading mechanism that transmits the movement from the tapping motor 64 to the kneading balls 51, and a tapping mechanism.

  The drive mechanism 60 is capable of tilting around the tilting shaft 53 with respect to the base portion 54 while supporting the kneading ball support arm 52 to which the kneading balls 51 are attached in a movable state. This is a mechanism that allows the user on the backrest part to advance and retreat and adjust the amount of protrusion of the kneading balls 51 toward the user. In order to tilt the drive mechanism 60, a partial gear 67 having a predetermined pitch circle diameter and a predetermined arc length around the tilt shaft 53 is fixedly disposed on the side of the housing 61. The kneading motor 62 and the tapping motor 64 operate in response to control signals output from the control unit 40, and provide various massage functions by the kneading balls 51 to the user.

The stagnation mechanism of the drive mechanism unit 60 is formed on the stagnation shaft portion 63 and a stagnation shaft portion 63 that is rotatably supported on the tilting shaft 53 in the housing 61 and is rotationally driven by the squeezing motor 62. The kneading ball support arm 52 is attached to the eccentric rotor portion 63a so as to be relatively rotatable. The kneading ball support arm 52 has a length from the portion supported by the kneading shaft portion 63 to the kneading ball mounting position, with at least the kneading balls 51 and the drive mechanism 60 tilted to the maximum extent by the user. The size is such that the kneading balls 51 can protrude beyond the back position of the user when leaning against the backrest 13 and the position closest to the user in the drive mechanism 60.

  Further, as the hitting mechanism of the drive mechanism portion 60, a hitting shaft 65 disposed in a housing 61 so as to be rotatable in a direction parallel to the tilting shaft 53, and an eccentric rotor portion formed on the hitting shaft 65. One end portion is attached to 65a so as to be relatively rotatable, and the other end portion is attached to a part of the kneading ball support arm 52 so as to be swingable, and the driving force of the tapping motor 64 is transmitted to the tapping shaft 65. This configuration includes a driving pulley 64a, a transmission belt 64b, and a driven pulley 64c.

  In the stagnation mechanism, the rotation of the stagnation motor 62 is transmitted to the stagnation shaft part 63 via a speed reduction mechanism (not shown), and the stagnation shaft part 63 rotates to rotate the stagnation shaft part 63 with respect to the tilting shaft 53. The eccentric rotor portion 63a which is inclined is rotated eccentrically around the tilt shaft 53, and the kneading ball support arm 52 attached around the eccentric rotor portion 63a is connected to the rod 66 on the hitting mechanism side. While being restrained, the eccentric rotor 63a is continuously swayed by the rotation of the eccentric rotor portion 63a. Along with this, the kneading balls 51 attached to one end of the kneading ball support arm 52 swings up and down, left and right and back and forth while drawing a continuous trajectory, thereby realizing a kneading as a treatment operation.

  Of the up / down, left / right, and front / back movements related to the kneading operation of the kneading balls 51, the front / rear movement components, that is, the movement of the kneading balls 51 that protrude toward the user and the movement of the movement away from the user Since the advancing / retreating movement of the kneading balls 51 with respect to the user with the tilting of the driving mechanism 60 around the tilting axis 53 is substantially matched with the direction of the movement, the kneading operation by the kneading mechanism of the driving mechanism 60 is performed. And the drive mechanism 60 by the tilting mechanism and the tilting motion of the kneading balls 51, the magnitude of the back and forth movement of the kneading balls 51, that is, the amount of protrusion of the kneading balls 51 with respect to the user in the kneading motion is arbitrarily adjusted it can. For example, in the case where the kneading balls 51 that are in contact with the body of the user move in a state where no pressing force is applied without moving back and forth, so-called “suri” movement is executed as a treatment operation, By the combined operation of the tilting mechanism, it is possible to cancel the component of the back and forth movement of the kneading ball 51 in the kneading operation, and at this time, the tilting operation by the tilting mechanism is a component of the back and forth movement of the kneading ball 51 in the kneading operation. By canceling only the effect, it is not necessary to consider the influence on the other motion components of the kneading balls 51, the control can be simplified, and the kneading balls do not move unnaturally, making the user feel uncomfortable. I don't give it.

  Further, in the hitting mechanism, the eccentric rotor portion 65a on the hitting shaft 65 and the other end portion of the kneading ball support arm 52 are connected by the rod 66, whereby the rod 66 is moved by the rotation of the eccentric rotor portion 65a, and the kneading ball is moved. A kind of crank mechanism that swings the support arm 52 around the eccentric rotor portion 63a on the kneading shaft portion 63 is configured, and the kneading ball 51 at one end of the arm also rocks by the rocking of the kneading ball support arm 52. Thus, it is a mechanism that realizes tapping as a treatment operation.

As for the movement of the kneading balls 51 that protrudes toward the user and the movement of the kneading balls 51 that move away from the user, the kneading balls that accompany the tilting of the drive mechanism 60 around the tilting shaft 53 are also used. 51, because the movement direction of the patient 51 substantially matches the direction of the movement, the hitting operation by the hitting mechanism of the drive mechanism unit 60 and the tilting operation of the drive mechanism unit 60 and the kneading balls 51 by the tilting mechanism. By the combination, the protruding amount of the kneading balls 51 with respect to the user in the hitting operation, that is, the hitting stroke can be arbitrarily adjusted. Further, the kneading balls 51 associated with the hitting operation
In accordance with the movement, the tilting operation by the tilting mechanism is executed at an appropriate timing, so that the strength of the hitting of the kneading balls 51 with respect to the user can be adjusted.

  The base portion 54 supports the drive mechanism portion 60 so as to be tiltable by supporting the tilt shaft 53. In addition, the base portion 54 is driven by a lift motor 57 that rotationally drives the tilt shaft 53 via a speed reduction mechanism. The mechanism portion 60 is tilted to move the kneading balls 51 forward and backward with respect to the user, and includes an advance / retreat motor 58 that adjusts the strength of treatment.

  The advancing / retracting motor 58 applies a rotational driving force to the pinion gear 58a meshed with the partial gear 67 on the side of the housing 61 in the drive mechanism 60 via the speed reduction mechanism, rotates the pinion gear 58a, and causes the partial gear 67 to move the tilt shaft 53. By moving it as the center, the tilt about the tilt shaft 53 of the drive mechanism 60 is realized. The advance / retreat motor 58 changes its drive state under the control of the control unit 40 based on information obtained by examining the body of the user (for example, a curve from the shoulder to the waist) before starting treatment. The drive mechanism 60 is tilted to move the kneading balls 51 forward and backward to adjust the amount of protrusion of the kneading balls 51 with respect to the user, so that optimal treatment can be provided for each user.

  The partial gear 67 on the side of the housing 61 is formed with a pitch circle radius as small as possible, and the covered gear 51 when tilted integrally with the drive mechanism 60 is leaned against the backrest 13. It is formed as a sufficient length in the circumferential direction that can provide a tilting range that can protrude beyond the back surface position of the user, and is disposed at a position near the tilting shaft 53 at the center. The pinion gear 58a meshing with the partial gear 67 is disposed in a cantilevered state protruding from the advance / retreat motor 58 and the speed reduction mechanism on the base portion 54 side to a position where it can mesh with the partial gear 67. There is no contact between the drive mechanism of the partial gear 67 including 58 a and the housing 61.

  Thus, the partial gear 67 and the pinion gear 58a are used to make the tilting mechanism of the drive mechanism 60 compact. This is because the kneading ball support arm 52 to which the kneading balls 51 are attached is supported by the kneading shaft 63. The kneading shaft portion 63 is mounted on the tilting shaft 53 so that the center position of the kneading shaft portion 63 coincides with the tilting shaft 53 that is the tilting center of the drive mechanism 60, and the force applied to the kneading balls 51 from the outside is supported by the kneading balls. This is because it is transmitted as it is to the tilting shaft 53 via the arm 52 and the squeezing shaft portion 63, and unnecessary force is not applied to the tilting mechanism of the drive mechanism portion 60, and the partial gear 67 and the pinion gear 58a have high strength. There is no need for a structure, and in particular, a simple tilting mechanism is realized by operating the pinion gear 58a as a cantilever without any problem.

  In addition, the partial gear 67 and the pinion gear 58a, which are simple and require little consideration of physical interference with the drive mechanism 60, can be disposed at a location near the tilt shaft 53 beside the drive mechanism 60. Compared with the case where the tilting mechanism of the drive mechanism unit is arranged at a position closer to the outer peripheral side than the drive mechanism unit with respect to the tilting shaft, the entire drive mechanism unit 60 can be downsized and the peripheral gear 67 can be easily rotated. A structure that can secure the length in the direction and increase the amount of protrusion of the kneading balls can be obtained without difficulty. In the structure in which the amount of protrusion of the kneading balls 51 can be increased, the kneading balls 51 in a protruding state can approach the user not only from the back side but also from the upper side and the lower side. Detection and massage operation by the kneading balls 51 can be efficiently executed. In particular, in the massage, the variation can be increased and a massage effect rich in change can be given.

The rotating body 55 is partly formed in a cylindrical shape and the other part is formed in a gear shape, and is fixedly supported on the shaft end of the tilting shaft 53 that is the central axis of rotation near the side end portion of the base portion 54, respectively. It is arranged so as to be rotatable with respect to the base portion 54 together with the tilting shaft 53, and the gear-like portion is connected to the pinion gear portion 55.
a is configured to mesh with the rack 21 of the guide frame 20. The pinion gear portion 55a of the rotating body 55 and the resin rack 21 formed with a sufficient width engage with each other while ensuring a wide contact area, whereby the rotating body 55 rotates and the pinion gear portion 55a and the rack 21 are engaged with each other. Even if the meshing state is changed, abnormal noise is hardly generated, and friction caused by contact can be suppressed to be small.

  In addition to the rotating body 55, guide rollers 59 are rotatably attached to the upper side end portions of the base portion 54. These guide rollers 59 are inserted into the guide frame 20 and guided together with the rotating body 55. By restraining the movement in the direction other than the longitudinal direction of the frame 20, the base part 54 can be moved in the vertical direction of the backrest part by the pair of guide frames 20, and supported in the other direction by restraining the movement in the other direction.

  The rotating body 55 rotates as the tilting shaft 53 is driven by the elevating motor 57, thereby changing the meshing position with the rack 21 and traveling the guide frame 20, and simultaneously starting with the base portion 54. The entire mechanical unit 50 is moved up and down the backrest 13 along the guide frame 20, whereby the treatment site by the kneading balls 51 can be changed up and down. When the mechanical unit 50 moves up and down, the elevating motor 57 is operated in response to a control signal output from the control unit 40, and the massager 51 receives various massages from the massager 51 on the backrest 13. It will be located at the most suitable place to provide for.

  Further, a plurality of rollers 56 are also arranged at the end of the base portion 54, and the pinion gear portion 55 a of the rotating body 55 meshes with the rack 21 while these rollers 56 maintain a distance from the rotating body 55. In this state, the rolling body 55 and the roller 56 are vertically in contact with the guide frame 20 while maintaining a state in which the rotating body 55 and the roller 56 sandwich a part of the guide frame 20 while being in contact with the outer peripheral surface of the guide frame 20 on the back side of the surface with the rack 21 , The rotating body 55 and the rack 21 are prevented from being separated from each other by the roller 56 and the meshing state is reliably maintained, and the rotating rotating body 55 can move up and down reliably with respect to the guide frame 20. The entire unit 50 can be accurately moved up and down, and the massaging balls 51 as the treatment element can be accurately adjusted to a desired vertical position. Further, the presence of the roller 56 allows the rotating body 55 to be positioned closer to the rack 21 regardless of the shape accuracy of the guide frame 20 to maintain the meshed state of the pinion gear portion 55a and the rack 21, thereby forming the guide frame with high accuracy and It is not necessary to secure high rigidity capable of maintaining the shape strictly against external force, and the structure of the guide frame can be simplified and reduced in weight.

  The armrest part 14 is located on both sides of the seat part 12 and is integrally connected to the base part 11. Even if the backrest part 13 changes the reclining angle or the seat part 12 tilts, the forearm of the user It is the structure formed so that it may be supported stably. The armrest portion 14 may also be configured such that an air cell that operates by supplying and discharging air by the air pump 70 can be provided to massage the forearm portion of the user.

  The leg support portion 15 is positioned on the front side of the seat portion 12 and is disposed so as to be tiltable about the vicinity of the front end of the seat portion 12, and the tilt angle is adjusted by a built-in actuator (not shown). A treatment mechanism 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 may also be provided in the leg support portion 15.

The remote controller 30 includes a large number of switches and display units for receiving various operation inputs to the massage machine, is detachably installed on the stand 16 on the side of the massage machine 1, and transmits operation inputs related to massage to the control unit 40. Is. Note that the position of the stand 16 can be adjusted so that the position of the switch and the display unit of the remote controller 30 is the optimum position for the user.

  The control unit 40 detects the position of each part of the body of the user using the mechanical unit 50 including the kneading balls 51, and based on the detection result, the other movable parts of the treatment mechanism and the massage machine are detected. In addition to adjusting to a state corresponding to the user, appropriate massage is performed based on the remote control operation, the massage contents recorded and set in advance, and the detection result information for the treatment mechanism and other movable parts. Operation control is performed.

  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 immediately below the seat 12 and is in a state where it can communicate with the remote controller 30, and the mechanical unit 50 and the backrest unit 13. And each actuator of the leg support 15 and the air pump 70 are electrically connected to each other, and when detecting the position of each part of the body of the user, a control signal is output based on a preset position detection program, and a massage is executed. In this case, these drive mechanisms are operated by a control signal output based on the set massage data. Further, the control unit 40 is also electrically connected to a 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 and the inclination of the backrest 13 and the leg support 15 are also shown. These operation controls are performed while grasping the state of the above.

  The control unit 40 controls the mechanical unit 50 to detect the position of each part of the body of the user prior to the massage, and moves the mechanical unit 50 along the guide frame 20 from the initial position of the backrest unit 13. In the process of moving the kneading balls 51 along the user, the change in the pressure on the kneading balls 51 from the user leaning against the backrest 13 and the change in the inclination of the kneading balls 51 are sequentially acquired. Based on this information, the shoulder position, spine line, and waist position of the user are detected. In particular, when detecting the shoulder position, the control unit 40 temporarily positions the kneading balls 51 above the shoulder, further tilts the drive mechanism 60, and puts the amount of protrusion of the kneading balls 51 toward the user back on the back. The size of the kneading ball 51 is lowered from above the shoulder of the user with the drive mechanism 60 (see FIG. 17A), and the size of the kneading ball 51 is lowered from the shoulder of the user. By detecting the state (see FIG. 17B) that has reached the upper shoulder side, the shoulder position of the user is detected and authorized.

  On the other hand, even in the case of massage, the control unit 40 performs a massage using this by having a mechanism in which the kneading balls 51 can protrude beyond the back position of the user leaning on the backrest 13. For example, after the kneading balls 51 are once positioned above the shoulders of the user, the control unit 40 tilts the drive mechanism 60 so that the amount of the kneading balls 51 protruding toward the user is increased. The size of the massaging ball 51 is lowered from above the shoulder of the user together with the drive mechanism unit 60 so that the massaging ball 51 reaches the shoulder upper side after the size of the back surface of the user leaning on the backrest portion 13 is exceeded. The massage operation for the upper shoulder portion of the kneading balls 51 can be executed (see FIG. 13A).

Conversely, the control unit 40 once places the massaging balls 51 below the waist of the user at the bottom of the backrest 13 and then tilts the drive mechanism 60 to move the massaging balls 51 toward the user. The amount of protrusion is set to be larger than the back position of the user leaning against the backrest 13, and the kneading balls 51 are raised together with the drive mechanism 60 from below the waist of the user, so that the kneading balls 51 are moved below the waist. It can also be made to reach the side, and the massage operation | movement with respect to the waist lower part of the kneading ball 51 can also be performed (refer FIG. 13 (B)).

  Next, the shoulder position detection operation of the user and the massage operation using the protruding kneading balls in the massage machine according to the present embodiment will be described. First, the shoulder position detection operation of the user will be described using the flowchart of FIG. As a premise, it is assumed that the main power of the massage machine 1 is turned on and the massage machine 1 is started in a state where the user is seated on the massage machine 1 and the back is leaned against the backrest 13.

  First, in the mechanical unit 50 in the initial position below the backrest 13, the control unit 40 operates the advance / retreat motor 58, drives the pinion gear 58 a to move the partial gear 67, and tilts the kneading balls 51 and the drive control unit 60. Then, the kneading balls 51 are directed toward the user (step S001). The control unit 40 also operates the lifting motor 57 to rotate the rotating body 55 and move the entire mechanical unit 50 upward with respect to the guide frame 20 (step S002). In this way, a state in which the kneading balls 51 are raised from below the backrest 13 while the kneading balls 51 are pressed against the back of the user is obtained (see FIG. 15). At this time, the kneading balls 51 are prevented from projecting on the back of the user and cannot move forward any further, so that the drive mechanism 60 cannot tilt, and the advancing / retracting motor 58 in operation is under a heavy load. It has become.

  When the kneading balls 51 continue to rise and reach a position beyond the shoulder (see FIG. 16A), the kneading balls 51 do not press the back of the user, and the kneading balls 51 are in the back of the user. By proceeding forward beyond the position, the drive mechanism 60 starts tilting, and the load on the advance / retreat motor 58 is suddenly reduced. The control unit 40 monitors the load of the advance / retreat motor 58 (step S003), and determines whether or not a state where the load suddenly decreases is reached (step S004). If it is determined that the load suddenly decreases, the control unit 40 recognizes the position of the kneading ball 51 at that time as the temporary position of the shoulder, and simultaneously stops the advancing / retreating motor 58 so that the kneading ball 51 and the drive control unit 60 The kneading balls 51 are prevented from tilting so that the kneading balls 51 do not protrude any more (step S005). On the other hand, if the load has not reached the state of sudden decrease in step S004, the process returns to step S003 again and the monitoring of the load of the advance / retreat motor 58 is repeated.

  After the temporary position of the shoulder is recognized, the control unit 40 continues the operation of the lifting motor 57 and moves the mechanical unit 50 upward (see FIG. 16B), while the advance / retreat motor 58 remains stopped, and the kneading balls A predetermined distance, for example, about 10 cm, is raised in a state where 51 is not advanced or retracted (step S006). After the ascent, the control unit 40 temporarily stops the elevating motor 57 and operates the advance / retreat motor 58 to tilt the kneading balls 51 and the drive control unit 60 again so that the kneading balls 51 protrude to the front side of the backrest 13 to the maximum. (Step S007).

  When the kneading balls 51 are protruded (see FIG. 17A), the control unit 40 stops the advance / retreat motor 58 and operates the elevating motor 57 to rotate the rotating body 55 in the opposite direction to the upward movement. Then, the kneading balls 51 are lowered together with the mechanical unit 50 (step S008). When the kneading balls 51 come close to the shoulder upper side (see FIG. 17B), the load on the elevating motor 57 increases rapidly as the descent speed of the kneading balls 51 decreases. The load is monitored (step S009), and it is determined whether or not a state in which the load increases rapidly (step S010). If it determines with having reached the state where load increases rapidly, the control part 40 will acquire the kneading ball position at that time, and will recognize this kneading ball position as a true shoulder position (step S011). On the other hand, if the load has not reached the state of sudden increase in step S010, the process returns to step S009 again, and the monitoring of the load on the lifting motor 57 is repeated.

When the true shoulder position is recognized, the control unit 40 temporarily stops the lifting motor 57 and then reverses it to raise the kneading balls 51 together with the mechanical unit 50 to separate the kneading balls 51 from the upper shoulder (
Simultaneously with step S012), the advancing / retracting motor 58 is operated to tilt the kneading balls 51 and the drive control unit 60, and the kneading balls 51 are moved away from the user, so that the kneading balls can be moved back and forth when the mechanical unit moves up and down. Retreat to a position where it does not physically interfere with the back of the user who leans on (step S013). Thereafter, when the control unit 40 temporarily stops the lifting motor 57 and then operates it again to move the mechanical unit 50 downward and return it to the initial position (step S014), a series of shoulder detection operations are completed.

  After the accurate shoulder position information is obtained in this way, the preparatory operation before the start of massage, such as weight measurement and position detection of other body parts such as the waist position, is performed by the control unit 40 as necessary. An operation state instruction such as a massage course is input by the user, and the control unit 40 receives the input, and a massage operation by each treatment mechanism is started. In the case of massage with the kneading balls 51, the control unit 40 operates the lifting motor 57 to rotate each rotating body 55 according to the set massage content, and the entire mechanical unit 50 is moved up and down with respect to the guide frame 20. Move and adjust the vertical position of the kneading balls 51, actuate the advance / retreat motor 58 to tilt the kneading balls 51 and the drive control unit 60, and adjust the amount of protrusion of the kneading balls 51 to the user, The massaging balls 51 are positioned at the massage target location. Thereafter, or in parallel with the movement of the kneading balls 51, the control unit 40 operates the kneading motor 62 and / or the tapping motor 64 according to the type of massage, and the kneading and tapping set in the kneading balls 51. The movement corresponding to the massage is performed.

  During massage, the kneading balls 51 are relatively pressed from the user side, and a pressing force is applied to the kneading balls 51, but the kneading balls supporting arm 52 to which the kneading balls 51 are attached is provided. The kneading shaft portion 63 is supported by the kneading shaft portion 63 and mounted on the tilting shaft 53 so that the center thereof coincides, and the force applied to the kneading ball 51 is tilted through the kneading ball support arm 52 and the kneading shaft portion 63. 53, the pinion gear 58a that forms the tilt mechanism of the drive mechanism 60 other than the tilt shaft 53 is not applied with a strong force via the drive mechanism 60, and the partial gear 67 is generated by the pinion gear 58a. Thus, the drive mechanism 60 can be smoothly tilted.

  Subsequently, the massage operation from above or below the user with the kneading balls with the kneading balls 51 projecting far beyond the back position of the user when the user leans against the backrest 13 explain.

  First, when massaging the shoulder of the user with the kneading balls 51 from above, the control unit 40 moves the lifting motor as necessary so that the kneading balls 51 are present above the shoulder position of the user. 57 is operated to rotate the rotating body 55 to move the entire mechanical unit 50 upward with respect to the guide frame 20 and raise the kneading balls 51 (see FIG. 16B). Then, in a state where the kneading balls 51 are present above the shoulder position of the user, the control unit 40 operates the advance / retreat motor 58 to tilt the kneading balls 51 and the drive control unit 60 to treat the kneading balls 51. The amount of protrusion to the person side is made larger than the back position of the user who leans against the backrest 13 (see FIG. 17A).

  Further, the control unit 40 stops the advance / retreat motor 58 and operates the elevating motor 57 to lower the kneading balls 51 together with the mechanical unit 50 so that the kneading balls 51 are detected in advance from a position above the shoulder of the user. The shoulder position is reached (see FIG. 17B). In this state, the control unit 40 operates the kneading motor 62 and / or the tapping motor 64 of the drive mechanism unit 60 to execute a massage operation of kneading and / or tapping on the shoulder upper portion of the kneading balls 51 (FIG. 13 ( A)). Thus, by performing massage such as massage or hitting with the kneading balls 51 on the shoulder from the upper side of the shoulder, a new massage effect different from the massage from the back side can be provided, and the treatment effect can be enhanced.

  In addition, when massaging the user's waist with the massage balls 51 from below, the control unit 40 moves the lifting motor as necessary so that the massage balls 51 exist below the waist position of the users. 57 is operated to rotate the rotating body 55 to move the entire mechanical unit 50 downward with respect to the guide frame 20 and lower the kneading balls 51. In a state where the kneading balls 51 are present below the waist position of the user, the control unit 40 operates the advancing / retreating motor 58 to tilt the kneading balls 51 and the drive mechanism 60 to treat the kneading balls 51. The amount of protrusion to the person side is made larger than the back position of the user who leans against the backrest 13.

  Further, the control unit 40 stops the advance / retreat motor 58 and operates the lifting motor 57 to raise the kneading balls 51 together with the mechanical unit 50 so that the kneading balls 51 reach just below the waist. In this state, the control unit 40 activates the kneading motor 62 and / or the tapping motor 64 of the drive mechanism unit 60 to execute a massage operation of kneading and / or tapping on the lower waist portion of the kneading balls 51 (FIG. 13). (See (B)). By performing massage such as massage or hitting with the kneading balls 51 on the waist from the lower waist side in this way, a new massage effect different from the massage from the back side can be given, and the treatment effect can be enhanced. .

  As described above, the massage machine according to the present embodiment disposes the drive mechanism 60 of the kneading balls 51 inside the backrest portion 13 so as to be tiltable, while the kneading ball support arm 52 in the drive mechanism 60 is kneaded. 63, and the squeezing shaft part 63 is mounted on the tilting shaft 53 so that the center position of the squeezing shaft part 63 coincides with the tilting shaft 53 that is the tilting center of the drive mechanism 60, and the force applied to the squeezing ball 51 is increased. By transmitting directly to the tilting shaft 53 via the kneading ball support arm 52 and the kneading shaft portion 63, unnecessary force is not applied to the drive portion that tilts the drive mechanism portion 60 from the kneading ball 51 side, and the pinion gear 58a is moved. It is not necessary to make the drive mechanism for tilting with high strength, and the drive mechanism for tilting can be simplified, the mechanical unit 50 can be downsized, and the cost can be greatly reduced. Achieved.

  In the massage machine according to the above embodiment, the kneading ball support arm 52 is attached to the kneading shaft portion 63 that forms a kneading mechanism by the drive mechanism portion 60 so as to be relatively rotatable, and the kneading shaft portion 63 is placed on the tilting shaft 53. The tilting shaft 53 is configured to pivotably support the kneading ball support arm 52 via the kneading shaft portion 63 so as to be swingable. However, the present invention is not limited to this, and the massage machine does not have a kneading function. When the portion 60 does not have a stagnation mechanism, the stagnation ball support arm can be directly attached to the tilting shaft, and the tilting shaft can be configured to support the stagnation ball support arm in a swingable manner. As the force applied to the kneading balls is transmitted to the tilting shaft as it is through the kneading ball support arm, unnecessary force is not applied to the tilting mechanism of the drive mechanism, and the tilting operation of the kneading balls and the drive mechanism Tilt stop With enhanced reliability and safety of the treatment operations during, some with no need to high strength tilt mechanism of the drive mechanism, simplifies the tilting mechanism, thereby the size of the entire mechanical unit.

  Further, in the massage machine according to the embodiment, the pinion gear portion 55a is provided on the rotating body 55 of the mechanical unit 50, while the guide frame 20 is provided with the rack 21, and the pinion gear portion 55a and the rack 21 are meshed to rotate. However, the present invention is not limited to this, and the rotating body to which the load of the mechanical unit is applied to the guide frame is not limited to this. A configuration in which the guide frame can be moved up and down without slipping and slipping, for example, a reverse unevenness corresponding to the unevenness formed in the rotating body is provided in the guide frame, and the rotating body is not displaced by engagement of the unevenness. It may be configured to be able to run up and down.
