  By the way, in the case of the massage apparatus by the said patent document 1, all the treatment mechanisms which implement | achieve three types of treatment are interlock | cooperating. Therefore, while the treatment is being performed by a certain treatment mechanism (for example, a kneading mechanism), other treatment mechanisms (for example, a roller hanging mechanism and a hitting mechanism) are also operated. On the other hand, if each treatment mechanism is configured to be able to operate independently, a large number of switches for operating each treatment mechanism are required, making it difficult to improve operability.

  Therefore, the present invention provides a massage apparatus that includes a plurality of treatment mechanisms corresponding to a plurality of placement postures, and that prevents other treatment mechanisms from operating during use and can improve operability. The purpose is to provide.

  The present invention has been made in view of the above-described circumstances, and a massage device according to the present invention includes a plurality of placement postures and a plurality of treatment mechanisms corresponding to the placement postures. When the posture is changed to a placement posture corresponding to another treatment mechanism during the operation of the other treatment mechanism, the operation of the one treatment mechanism is stopped.

  With this configuration, when the mounting posture is changed, the treatment mechanism that has been operating before the change can be stopped, and switches for stopping the treatment mechanism before the posture change can be performed. Therefore, the operability can be improved.

  Further, when the posture is changed to the placement posture corresponding to the other treatment mechanism during the operation of one treatment mechanism, the operation of all the treatment mechanisms may be stopped. By adopting such a configuration, after changing the posture, all the treatment mechanisms can be stopped until the user intends (that is, until the next treatment is intended). Therefore, even if the mounting posture of the massage device is changed unintentionally, all the treatment mechanisms are stopped, so that no malfunction occurs due to the operation of the treatment mechanism.

  In addition, the apparatus further includes a control unit that controls the operation of the treatment mechanism, and a posture detection sensor that detects the mounting posture. When a signal indicating a change in the mounting posture is detected from the posture detection sensor, the control unit May be configured to stop the operation of the treatment mechanism. With such a configuration, it is possible to specifically realize the operation stop of the treatment mechanism by changing the posture.

Moreover, when it arrange | positions with one side facing down in this way, the top part in the peripheral part of a housing | casing will be located upwards. Therefore, by setting the treatment position on the top, the body part can be easily placed at the treatment position, and the user can easily treat the body part.

  In addition, a support portion that supports the housing on the floor surface in each mounting posture is provided at an end portion in the axial direction of the housing, and the support portion is more cylindrical than each treatment mechanism. You may be comprised so that it may protrude in the direction away from the axial center of the housing | casing. With such a configuration, when the massage apparatus is placed on the floor surface, the treatment mechanism does not come into contact with the floor surface in any placement posture.

  The treatment mechanism may include at least one of a squeezing mechanism for rubbing and treating the body part, a rubbing mechanism for rubbing and treating the body part, and a reciprocating mechanism for reciprocating and treating the body part. . By setting it as such a structure, three types of different treatment can be implement | achieved by one massage apparatus.

  Further, a plurality of motors for operating the plurality of treatment mechanisms may be provided, and the motors may be arranged separately on both end sides of the casing. With such a configuration, the weight balance of the housing in a state in which the motor is accommodated becomes good, and a stable mounting posture can be taken.

  Further, the treatment mechanism includes at least the reciprocating mechanism, and the reciprocating mechanism has a placing portion on which a body part is placed and reciprocates, and the placing portion is formed of a flexible material. Also good. By setting it as such a structure, the mounting | wearing comfort at the time of mounting and treating a body part on a mounting part becomes favorable. Further, as described above, in the case where the support portion protruding to support the housing is provided on the floor surface, even if the body part is located between the support portion and the placement portion that reciprocates, the placement portion. Since it has flexibility, it can prevent that the said body part is pinched strongly.

However, the portion 26b on the left side (center side of the squeezing mechanism 4) of the hollow shaft 26 of the inner pressing portion 23 of the right second treatment portion 21 is the inner side of the left second treatment portion 21. Of the hollow shaft 26 included in the pressing portion 23, the inner diameter dimension of the portion 26 c on the right side (center side of the stagnation mechanism 4) from the pressing disk 27 is smaller. The right portion 26c is inserted into the left portion 26b, and the left and right inner pressing portions 22, 22 are movable in the left-right direction so that they can approach and separate from each other. .

  In addition, spacers 28 and 28 are disposed on the outer side of the pressing disk 25 of the outer pressing portion 22 included in the left and right second treatment portions 20 and 21. The spacer 28 is configured such that one end of a cylindrical member having a slightly smaller diameter than the pressing disk 25 is cut obliquely, and is used to fill a gap on the outer side of the pressing disk 25. Similarly, spacers 29 and 29 are disposed between the pressing disks 27 and 27 of the inner pressing portion 23 of the left and right second treatment portions 20 and 21. The spacer 29 also has a configuration in which one end of a cylindrical member having a slightly smaller diameter than the pressing disk 27 is obliquely cut, and is used to fill a gap between the pressing disks 27 and 27. Further, the inner diameter of the left spacer 29 is slightly larger than the outer diameter of the right spacer 29, and the right spacer 29 extends along the shaft core 4c while being partially inserted into the left spacer 29. It can be slid in any direction.

  A rotation shaft 30 for rotating the left and right second treatment portions 20 and 21 is provided in the internal space of the hollow shafts 24 and 26, and the rotation shaft 30 is spline-coupled to the hollow shafts 24 and 26. ing. Accordingly, the hollow shafts 24 and 26 are movable independently of the rotary shaft 30 in the left-right direction along the axis of the rotary shaft 30, while being integral with the rotary shaft 30 in the circumferential direction of the rotary shaft 30. It is only rotatable. In addition, when inserting the outer side press part 22 and the inner side press part 23 in the rotating shaft 30, the inclination direction with respect to the axial center 4c of the center axis | shaft of each press disk 25 and 27 is made mutually reverse. Accordingly, there are a small part and a large part in the separation distance between the pressing disks 25 and 27 arranged opposite to each other.

  The left end portion of the rotating shaft 30 is rotatably supported by a bearing portion 32 provided on the left side wall 2a of the housing 2, and the bearing portion 32 provided on the right side wall 2b of the housing 2 is also provided near the right end portion.

It rotates in the state which contacted the outer side part and inner side part. Since the central axes of the pressing discs 25 and 27 are inclined by a predetermined angle with respect to the shaft core 4c, the left and right pressing discs 25 and 27 move closer to and away from the leg portions as they rotate. This operation is repeated, and this operation becomes a stagnation operation for the leg.

  Moreover, since the inner side press parts 23 and 23 of the 2nd treatment parts 20 and 21 can be slid to right and left along the rotating shaft 30, the outer side press part 22 respond | corresponds to the difference in a leg size of a user. Distance, that is, the separation distance between the pressing disc 25 of the outer pressing portion 22 and the pressing disc 27 of the inner pressing portion 23 is changed. Further, as shown in FIG. 4, a spring spring 38 as an urging means is attached between the pressing disks 25 and 27 in the inner space of the central spacers 29 and 29. The spring spring 38 urges the left and right pressing disks 25 and 27 outward in the left-right direction (that is, in a direction in which both are separated). Accordingly, the pressing disks 25 and 27 are pressed against the legs of the user by an appropriate pressing force generated by the biasing force of the spring spring 38.

  By the way, as shown in FIG.2 (b), in the massage apparatus 1 of a 2nd attitude | position, the rectangular shape is comprised by planar view at the upper part of the housing | casing 2, and the long opening 2d is formed in the left-right direction. . When the stagnation mechanism 4 described above is accommodated in the housing 2, the substantially upper half of the second treatment portions 20 and 21 is exposed outward from the opening 2d. Therefore, when the user places the leg portion on the upper portion of the massage apparatus 1 in the second posture and drives the rubbing mechanism 4, the second treatment portions 20 and 21 are rotationally driven, and the pressing disks 25 and 27 arranged to face each other. Treat the legs from left and right. Moreover, since the treatment protrusions 25b and 27b are attached to the press discs 25 and 27, it is possible to effectively squeeze the legs by the treatment protrusions 25b and 27b. In practice, the opening 2d shown in FIG. 2 (b) is covered with a cloth cover (not shown) that matches the shape of the exposed portions of the second treatment portions 20, 21. The pressing discs 25 and 27 and the treatment protrusions 25a and 27a are in contact with each other through this cover.

Is housed. Further, the spur gear 53 and the crank 49 are coaxially connected through a vertical through hole 56 b formed in the upper case 56.

  As already mentioned in the description of the kneading mechanism 4, the driven pulley 35c connected to the worm 52 is connected to the drive pulley 35a attached to the output shaft 34a of the second motor 34 via the belt 35d. Yes.

  The slide mechanism 5 having such a configuration is driven by the second motor 34 that has driven the stagnation mechanism 4. As described above, the stagnation mechanism 4 is driven when the output shaft 34a of the second motor 34 rotates in one direction. When the output shaft 34a rotates in the other direction, the slide mechanism 5 is driven.

More specifically, as shown in FIG. 5, when the second motor 34 is driven and the output shaft 34a rotates in the other direction, the large-diameter driven pulley 35b and the small-diameter driven pulley 35c rotate. The rotation of 35b is not transmitted to the drive gear 33b, and the stagnation mechanism 4 does not operate. On the other hand, the rotation of the driven pulley 35c is transmitted to the crank 49 via the worm 52 and the spur gear 53, and the crank 49 is rotated. When the crank 49 rotates, the conversion member 47 jointed through the boss portion 49a and the long hole 47a reciprocates in the left-right direction, and the rotational motion is converted into a linear motion.

  When the conversion member 47 reciprocates, the slider 42 connected thereto slides in the left-right direction along the guide pole 45, and the leg placement unit 40 connected to the upper portion of the slider 42 also slides in the left-right direction. Become. Therefore, when the slide mechanism 5 is operated in a state where the legs are supported by the recesses 40a of the leg placement unit 40, the legs of the user are centered on the hip joint as the leg placement unit 40 reciprocates. Swinging to the left and right, such movement is effective for hip joint treatment.

  In addition, the reciprocating distance by which the leg mounting part 40 slides is equal to the distance from the rotation center of the crank 49 to the boss part 49a. Further, when the output shaft 34a of the second motor 34 rotates in one direction, the rotation of the driven pulley 35c is not transmitted to the worm 52 by the action of the one-way clutch 60, and the slide mechanism 5 does not operate. Yes. Further, as shown in FIG. 2C, in the massage device 1 in the third posture, the treatment position 5 a by the slide mechanism 5 is set on the upper portion of the housing 2, and only the leg placement unit 40 is the housing 2. It is exposed outside.

  In addition, among the treatment mechanisms 3 to 5 described so far, the stagnation mechanism 4 and the slide mechanism 5 are driven by the same second motor 34, and therefore when the treatment mechanisms 4 and 5 are driven by separate motors. Compared to the number of heavy motors, the massaging device 1 can be reduced in weight. In addition, the massage apparatus 1 includes a total of two motors 17 and 34 for driving the treatment mechanisms 3 to 5, and these motors 17 and 34 are arranged separately on the left and right sides in the housing 2. Thus, since the motors 17 and 34 which are comparatively heavy objects are located in the both sides, the weight balance of the massage apparatus 1 is ensured favorable.

  By the way, the massage apparatus 1 according to the present embodiment includes the contact sensor 78 (see FIG. 9) that detects that an object has been sandwiched between the leg placement unit 40 and the support unit 90. It is possible to prevent the slide mechanism 5 from continuously operating while being sandwiched. That is, the contact sensor 78 is appropriately provided on the surface of the support portion 90 that faces the leg placement portion 40, and is connected to the control portion 70 as shown in FIG. When it is detected that an object is sandwiched between the support unit 90 and the detection signal, the detection signal is output to the control unit 70. And the control part 70 will stop the 2nd motor 34, if this detection signal is received. Therefore, even if an object is caught between the leg placement unit 40 and the support unit 90, the operation of the leg placement unit 40 is stopped by the stop of the second motor 34, so that the object remains in the sandwiched state. It is possible to prevent the slide mechanism 5 from continuously operating.

[Attitude detection]
FIG. 9 is a schematic block diagram showing functions of the massage apparatus 1 having the above-described configuration. As shown in FIG. 9, the massage apparatus 1 includes a control unit 70, and the control unit 70 is accommodated in the housing 2 (see FIG. 1). The control unit 70 is connected to the first motor 17 and the second motor 34 described above via the drive units 71 and 72, respectively. Accordingly, the drive units 71 and 72 output predetermined electrical signals according to the control signal from the control unit 70, and the first motor 17 and the second motor 34 are individually driven and controlled based on the electrical signals. Then, the rubbing mechanism 3 is operated by driving the first motor 17, and the rubbing mechanism 4 and the slide mechanism 5 are selectively operated by driving the second motor 34.

  In addition, an attitude detection sensor 74 is connected to the control unit 70. The posture detection sensor 74 detects the posture (first to third postures) of the massage device 1, and is configured by a proximity switch as schematically illustrated in FIG. More specifically, the attitude detection sensor 74 has three magnetic sensors 76 a to 76 c attached on the substrate 75 and a rotating magnetic piece 77. The three magnetic sensors 76a to 76c are arranged at equal intervals (that is, intervals of 120 degrees) along a concentric circle centered on the predetermined point 75a, and each of the magnetic sensors 76a to 76c is in the first to third postures. It corresponds. The rotating magnetic piece 77 includes a turning member 77a that is rotatably supported at a predetermined point 75a, and a magnet 77b attached to the tip of the turning member 77a (an end portion separated from the predetermined point 75a). The magnet 77b faces the three magnetic sensors 76a to 76c in the middle of the rotation path (coincident with the concentric circle) when the turning member 77a rotates.

  Such a posture detection sensor 74 is attached in the vicinity of the left side wall 2a of the massage device 1 so that the rotation axis of the turning member 77a coincides with the left-right direction. The swing member 77a is configured such that the magnet 77b is positioned vertically below the predetermined point 75a by its own weight regardless of whether the massage device 1 is in the first to third postures. Therefore, when the massage device 1 is in the first posture, the magnetic sensor 76a is positioned so as to face the magnet 77b (the state shown in FIG. 9), and the massage device 1 detects the magnetism generated by the magnet 77b. A signal indicating that one posture is taken is output to the control unit 70.

  Similarly, when the massage apparatus 1 is in the second posture, the magnetic sensor 76b is positioned so as to face the magnet 77b, and the magnetic sensor 76b sends a signal to the control unit 70 that the second posture is taken. Output. When the massage apparatus 1 is in the third posture, the magnetic sensor 76c is positioned so as to face the magnet 77b, and the magnetic sensor 76c outputs a signal indicating that the third posture is taken to the control unit 70.

  Based on these signals from the posture detection sensor 74, the control unit 70 determines which of the first to third postures the massage device 1 is in, and the input of these signals is interrupted, or another When the signal is switched, it is determined that the posture has been changed. When the control unit 70 determines that the posture has been changed, the control unit 70 controls to stop the operation of all of the treatment mechanisms 3 to 5 regardless of whether or not the posture is being changed. For example, if the second posture is changed while the rubbing mechanism 3 is operating in the first posture, all the treatment mechanisms 3 to 5 including the rubbing mechanism 3 are stopped.

  In the above description, the case where all the treatment mechanisms 3 to 5 are controlled to be stopped when the posture is changed is described, but the present invention is not limited to this. When the posture is changed, the pre-change treatment mechanism (for example, the rubbing mechanism 3) is stopped, while the treatment mechanism (for example, the itch mechanism 4) corresponding to the post-change posture (for example, the second posture). It may be controlled to start the operation.

  By adopting such a configuration, there is no need to separately perform an operation for stopping the operation of the treatment mechanism in one posture when treatment is performed in another posture after treatment in one posture. The operability can be improved. Moreover, since the number of switches of the massage apparatus 1 can be reduced in connection with this, the cost of the massage apparatus 1 can be reduced.

  Incidentally, as will be described later, the slide mechanism 5 is disposed between the pair of support portions 90 and 90, and the leg placement portion 40 reciprocates between the support portions 90 and 90 (see FIG. 1). When any object is sandwiched between the support 90 and the leg placement unit 40, the leg placement unit 40 has flexibility as described above. By bending, it is possible to avoid damage to the massage device 1 or the object.

  Moreover, as already explained, the massage device 1 according to the present embodiment includes the contact sensor 78. When the contact sensor 78 detects that an object is caught between the leg placement unit 40 and the support unit 90, the detection signal is output to the control unit 70. The control unit 70 outputs a control signal to the drive unit 72 based on the detection signal, and stops the second motor 34. Therefore, when an object is caught between the leg placement unit 40 and the support unit 90, it is possible to detect this and stop the second motor 34, and to stop the operation of the leg placement unit 40.

  On the other hand, as shown in FIG. 9, a power switch 80 is connected to the control unit 70, and by operating this switch, power supplied from a commercial power source provided at home through a power cable (not shown) is obtained. It is possible to switch whether to input power to the control unit 70 and the drive units 71 and 72. Further, a receiver 81 capable of receiving infrared signals is connected to the controller 70 so that it can receive infrared signals emitted from the remote controller 82 and input them to the controller 70.

[Remote controller]
FIG. 10 is an external plan view of the remote controller 82 shown in FIG. The remote controller 82 has a relatively thick disc-shaped main body 82a, and five switches 83a to 83e are arranged on the upper surface thereof. By pressing these switches 83 a to 83 e, an infrared signal can be emitted from an output unit (not shown). This signal is received by the receiving unit 81 of the massage device 1 and input to the control unit 70.

  The switches 83a to 83e will be specifically described. An on / off switch 83a is provided at the center of the main body 82a. By pressing this switch 83a, it is possible to operate or stop the treatment mechanism corresponding to the posture of the massage device 1 among the treatment mechanisms 3 to 5. In FIG. 9, a speed-up switch 83b is provided obliquely above and to the right of the switch 83a, and a speed-down switch 83c is provided obliquely above and to the left. These switches 83b and 83c are for adjusting the operating speed of the treatment mechanisms 3 to 5, and the operating speed increases every time the switch 83b is pressed, and the operating speed decreases every time the switch 83c is pressed.

  In addition, a first roller switch 83d and a second roller switch 83e that determine the rotation direction of the first treatment unit 10 included in the rubbing mechanism 3 are provided on the lower right and lower left sides of the switch 83a. Of these, when the switch 83d is pressed, the first treatment unit 10 rotates in one direction, and when the switch 83e is pressed, the first treatment unit 10 rotates in the other direction.

  Thus, in this Embodiment, since the massage apparatus 1 is comprised so that the treatment mechanisms 3-5 may be automatically stopped by the change of an attitude | position as mentioned above, in the remote controller 82, the above-mentioned It is only necessary to provide such five switches 83a to 83e. Therefore, the operation of the remote controller 82 (operation of the massage apparatus 1) is simple, and the remote controller 82 can be downsized. Since the remote controller 82 is downsized, in the present embodiment, the remote controller 82 is detachably attached to the right end surface of the massage apparatus 1.

[Floor support structure]
Incidentally, as shown in FIG. 1, the massage device 1 has a substantially triangular prism shape as viewed from the outside. And the support part 90 which contacts this floor surface and supports the massage apparatus 1 when the massage apparatus 1 is mounted in a floor surface is provided in the edge part of the longitudinal direction. More specifically, each end of the housing 2 in the direction (left-right direction) along the axis 1a and having a substantially triangular prism shape is located outside the peripheral surface of the housing 2. A support portion 90 is provided so as to protrude in the direction (direction away from the shaft core 1a). Accordingly, three support portions 90 are provided at equal intervals along the circumferential direction at one end portion of the housing 2, and three support portions 90 are also provided at equal intervals along the circumferential direction at the other end portion. It has been.

  Further, between the pair of support portions 90 provided at both ends of each top portion, one corresponding to any of the treatment mechanisms 3 to 5 is disposed, and the pair of support portions 90 are located between the pair of support portions 90. It protrudes outward from the treatment mechanisms 3-5. These support parts 90 have an arcuate outer periphery when viewed from the side, and a non-slip 91 made of synthetic resin is affixed to the end face.

  The state in which such a massage device 1 is placed on the floor surface in the first to third postures is shown in FIG. 2, and in each posture, there are two massage devices 1 on the left and right sides (that is, a total of four). Is supported on the floor surface by the support portion 90. Moreover, since the support part 90 protrudes outward rather than the treatment mechanisms 3-5 at this time, it can avoid that the treatment mechanisms 3-5 contact a floor surface directly. Furthermore, the massage device 1 is stably placed on the floor surface by the non-slip 91 attached to the end surface of the support portion 90.

  As shown in FIG. 1, on the left and right end surfaces of the massage device 1, grip portions 92 that are recessed in the vicinity of the respective support portions 90 are formed. Therefore, when carrying the massage device 1 or changing the posture, the user can hold and hold the grip portion 92 and the end surface of the support portion 90 with each other. Further, the anti-slip 91 affixed to the end face of the support portion 90 exhibits an anti-slip effect on human hands when it is lifted in this way.
