Description

  The present invention relates to a massage machine that can adjust the position of a treatment element such as a kneading ball up and down by a backrest portion, and more particularly to a mechanism that moves a treatment element and its drive mechanism up and down with a wire.

  In a chair-type massage machine that performs a massage operation while supporting the body of the user, usually, a treatment element such as a kneading ball provided on the backrest part can be moved in the vertical direction of the backrest part. It has a configuration that enables a treatment operation to a desired treatment position. With such a massage machine, as a mechanism to move the treatment element up and down at the backrest part, the drive mechanism part of the treatment element is supported by the guide rail built in the backrest part so that it can be moved up and down, and arranged on the drive mechanism part side The drive mechanism unit and the back of the treatment element are vertically moved and stopped by meshing with the gears to be rotated and the teeth (rack) fixedly arranged in the longitudinal direction of the rail on the guide rail side. Mechanisms that enable maintenance were commonly used. One example of a massage apparatus that employs such a moving mechanism is disclosed in Japanese Patent Application Laid-Open No. 10-211246.

  In addition, as another mechanism for moving the treatment element in the chair-type massage machine, the drum wound with the wire passed between the frames arranged at the top and bottom in the backrest portion is rotated to change the winding state of the wire. A device has also been proposed in which the drum position is moved up and down to move the treatment element integrated with the drum and its drive mechanism in the vertical direction of the backrest. An example of a massage apparatus that employs such a moving mechanism is disclosed in Japanese Patent Publication No. 59-34375.

Japanese Patent Laid-Open No. 10-211246 Japanese Patent Publication No.59-34375

  The mechanism for moving the treatment element up and down in the conventional massage machine is configured as shown in the above-mentioned patent documents, and the former mechanism is a movable part that appropriately moves the treatment element and its drive mechanism part up and down while stopping. Can be held without shifting up and down, but the teeth engage each other during the movement, so a meshing sound is generated simultaneously with the vertical movement of the treatment element and is transmitted to the outside of the backrest as noise. In addition, there is a problem that the generated sound becomes loud unless the processing accuracy of the gears and teeth is set appropriately. Also, in order to smoothly move the drive mechanism up and down, teeth are provided on both the left and right guide rails, and driving gears that engage with the teeth are provided respectively, so that the vertical movement force is balanced in the lateral direction of the backrest. The structure to be generated is required, and in addition to such a complicated structure, it is necessary to ensure the processing accuracy of each tooth, which has a problem of increasing the manufacturing cost.

  On the other hand, the up-and-down movement mechanism of the treatment element in the latter conventional massage machine can be made a relatively simple structure by using a wire and does not generate a meshing sound, but the winding state of the wire around the drum is aligned. Since it is difficult to do so, if the wire is wound around the drum to some extent so that the wire and the drum do not slip each other, the wires wound on the drum can easily come into contact with each other, and abnormal noise is generated due to this contact. Or the wire may be worn out and deteriorated.

  In addition, the wire supports the load of the drive mechanism and the treatment element. However, the wire is tensioned by the load of the drive mechanism and the treatment element on the upper part of the wire drum, and the wire is reversed on the lower side of the drum. It is easy to cause slippage of the drum and wire and fluctuation of the vertical position of the drive mechanism, and when the body is added to the backrest and weight is added to the treatment element, the expectation of the drive mechanism There was a problem that an unintentional movement might be caused, leading to rattling of the treatment element.

  The present invention has been made in order to solve the above-described problems, and allows the therapeutic element and its drive mechanism to be moved up and down with a simple structure using wires, while ensuring operational reliability and safety. It is an object of the present invention to provide a massaging device moving mechanism for a massage machine that can reduce costs, hardly generate noise, and can improve quietness.

  The treatment element moving mechanism of the massage machine according to the present invention is a treatment element movement mechanism of a massage machine that can adjust the vertical position of the predetermined treatment element arranged on the backrest part with respect to the backrest part together with the drive mechanism part of the treatment element. A plurality of guide rails that are disposed inside the backrest portion and are capable of moving the drive mechanism portion in the vertical direction of the backrest portion and restraining movement in other directions and supporting the drive mechanism portion in the vertical direction; A drum that is arranged integrally with the drive mechanism unit so as to be rotatable about an axis orthogonal to the direction of movement to the drum, and is driven to rotate by a predetermined drive source, and at least one end being wound around the drum a predetermined number of times Is held at the end in the vertical direction inside the backrest and stretched up and down inside the backrest, and the winding state of the drum is changed as the drum rotates. A wire that moves the belt in the vertical direction with respect to the backrest portion, and tension means that is attached to the end portion of the wire or in contact with the intermediate portion of the wire, and maintains the wire in a relaxed state based on elastic force. It is to be prepared.

  Thus, according to the present invention, the drive mechanism portion of the treatment element is disposed in the backrest portion so as to be movable in the vertical direction, while the wire is wound around the drum disposed in the drive mechanism portion and the end portion of the wire is attached to the drum. The drum is moved while changing the wire winding state on the drum by rotating the drum while securing the tension of the wire by the tension means while holding it in the backrest, and the treatment element integrated with this drum and its drive mechanism section Also, by moving it vertically, it is possible to move it smoothly in the vertical direction while reliably supporting the weight of the treatment element and its drive mechanism with the wire, simplifying the support structure of the treatment element and drive mechanism The cost is greatly reduced and the gear mechanism is not used for the vertical movement, so that the gear meshing noise is not generated, the quietness is improved, and the noise interferes with the relaxing state by massage. To become and can be prevented. In addition, the tension of the wire that supports the treatment element and the drive mechanism can be prevented by the tension means, the contact between the drum and the wire can be reliably moved without slipping, and the drum and the wire are brought into close contact even when the drum is stopped. Thus, slippage between the drum and the wire can be suppressed, and the movement stop state of the treatment element and the drive mechanism can be maintained, and the reliability and safety of the movement operation and the treatment operation at the time of the stop can be improved.

  Further, the treatment element moving mechanism of the massage machine according to the present invention is provided with a first drum for upward movement and a second drum for downward movement, respectively, as the drum, as necessary. A first wire having one end connected to an upper end inside the backrest and the other end wound around the first drum; and one end at the lower end inside the backrest And a second wire that is connected to the other end and wound around the second drum, and the first drum and the second drum are simultaneously rotated in the same rotational direction, The wire is wound up, and the other is set in a state where the wire is sent out, and similarly moves in the vertical direction of the backrest portion to change the vertical position of the treatment element and the drive mechanism portion.

  As described above, according to the present invention, the first wire having the end portion connected to the upper end portion inside the backrest portion is wound, and moves upward as the wire is wound, and the end portion is the backrest. The second wire held at the lower end inside the unit is wound, and a second drum that moves downward as the wire is wound is disposed, and the treatment element and its drive mechanism are moved upward. By making the drum used for the drum and the drum used for the downward movement independent from each other, the end of each wire can be fixed to the drum, and the wire can be wound around the drum.

  The guide rails 11 and 12 have a substantially U-shaped cross-sectional shape and are formed in a longitudinal direction along the surface of the backrest portion 93 in accordance with the shape of the back of the person, as shown in FIG. 93, the frame 97 is fixed to the right frame 97c and the left frame 97d, and a pair is disposed on the left and right sides of the backrest portion. The mechanical unit 60 is disposed so as to be movable along the guide rails 11 and 12 in an arrangement sandwiched between the two guide rails 11 and 12 forming a pair.

  The mechanical unit 60 has a pair of left and right rubbing balls 61 as a treatment element that gives the user a stimulus such as hitting and hitting on the backrest portion 93, and corresponding to massage operation such as hitting and hitting. The kneading ball driving unit 62 that drives the kneading ball and the base unit 63 that supports the kneading ball driving unit 62 so as to be tiltable (see FIG. 3). It has a mechanical part. Two drums 13 and 14 are rotatably supported on the base portion 63 of the mechanical unit 60, and the drums 13 and 14 are rotationally driven with the wires 15 and 16 wound around them.

  The kneading ball drive unit 62 includes a kneading motor 64 that applies a driving force for causing the kneading ball 61 to perform a kneading operation, and a tapping motor 65 that provides a driving force for causing the kneading ball 61 to perform a tapping operation ( 4), the kneading balls 61 are supported in a movable state. The kneading ball drive unit 62 is attached to the base portion 63 so as to be tiltable on the lower side of the mechanical unit 60, and has a mechanism capable of adjusting the amount of the kneading ball 61 protruding to the back side.

  The base portion 63 moves the drums 13 and 14 in rotation, and the kneading ball driving portion 62 is tilted to move the kneading balls 61 forward and backward to adjust the strength of treatment. It is a structure provided with the motor 67 (refer FIG. 4). The kneading motor 64 and the hitting motor 65 of the kneading ball driving unit 62 and the lifting motor 66 and the advancing / retracting motor 67 of the base unit 63 are operated in response to control signals output from the control unit 82, respectively. Various massage functions according to 61 will be provided to the user.

  As shown in FIGS. 2 to 5, guide rollers 68a, 68b, 68c, and 68d are rotatably attached to the side end portions of the base portion 63, respectively. These guide rollers 68a, 68b, 68c, and 68d are inserted into the guide rails 11 and 12 to restrain the movement of the guide rails 11 and 12 other than in the longitudinal direction. 12 is a mechanism supported so as to be movable up and down along the line 12.

  The drums 13 and 14 include a first drum 13 for moving the mechanical unit 60 upward and a second drum 14 for moving the mechanical unit 60 downward. On both sides of the kneading balls 61 and the kneading ball driving portion 62 to be arranged, the drums are arranged to be spaced apart from each other and fixedly supported by the base portion 63 so as to be rotatable (see FIG. 3), and driven by the lifting motor 66. As the wire 15 or 16 is wound or delivered, the wire 15 or 16 moves relative to the wire, and at the same time, the entire mechanical unit 60 is moved along the guide rails 11 and 12 above and below the backrest 93. The treatment site by the kneading balls 61 is changed up and down.

  The first drum 13 and the second drum 14 are formed with the same cylindrical drum body diameter, and are arranged on the same drive shaft, and are simultaneously rotated in the same rotational direction by the lifting motor 66. The winding state of the wires 15 and 16 is changed to similarly move in the vertical direction with respect to the backrest portion 93, and at the same time, the vertical position of the mechanical unit 60 is changed. In any rotation direction, the wire is drawn out by one drum and the wire is wound by the other drum.

  When the first drum 13 and the second drum 14 are rotated to move the mechanical unit 60 up and down, the first drum 13 that receives a tensile force upward based on the tension of the wire, and the downward direction based on the tension of the wire The second drum 14 that receives a pulling force is disposed on both sides of the center position between the left and right guide rails 11 and 12 so as to be substantially symmetrical with each other. Is a rotationally symmetric relationship with respect to the center position between the drums in the mechanical unit 60, and moments having substantially the same magnitude are generated in the same direction (clockwise in FIGS. 2 and 3) in the mechanical unit 60. On the other hand, in each guide roller 68a, 68b, 68c, 68d, the contact state with the guide rails 11 and 12 is made appropriate to alleviate excess force accompanying the moment, and the mechanical unit 60 for the guide rails 11 and 12 is relieved. To maintain a smooth up and down movement. However, in any movement of the mechanical unit 60 up and down, the direction of the moment is only one direction and the other directions need not be taken into consideration, so that the smooth movement of the mechanical unit 60 can be realized with a relatively simple structure. . In addition, as long as the direction of the moment by the force applied from each wire is the same, the magnitude | size may differ, Each distance from the center position between the guide rails 11 and 12 to the 1st drum 13 and the 2nd drum 14 The drums may be arranged so that they are different from each other.

  Since the first drum 13 and the second drum 14 have a kneading ball 61 and a kneading ball driving unit 62 disposed in the center between the guide rails 11 and 12, the first drum 13 and the second drum 14 are arranged between the guide rails 11 and 12 so as to avoid them. Although the drums are arranged at positions other than the center, the positions of the respective drums are not limited to the positions where the drums are spaced apart from each other. Can be arranged close to each other.

  As shown in FIG. 2, the wires 15 and 16 are held at one end by an upper frame 97a positioned at the upper end inside the backrest 93, and the other end is fixed to the first drum 13 and predetermined. The first wire 15 is wound for a length, and one end is held by the lower frame 97b located at the lower end inside the backrest 93, and the other end is fixed to the second drum 14. The second wire 16 is wound for a predetermined length. When the drums 13 and 14 are stopped, the drum position is held by the wire tension, and the mechanical unit 60 integrated with the drums 13 and 14 is vertically moved. While maintaining the position, when the drums 13 and 14 are rotated, the drums 13 and 14 are relatively moved in the vertical direction as the winding state of the drums 13 and 14 is changed. It is intended to allow vertical movement relative to the backrest 93.

  As shown in FIG. 2, the spring 17 is disposed between the lower end portion of the second wire 16 and the lower frame 97b of the lower end portion of the backrest portion as an elastic body that forms tension means, By pulling the second wire 16 downward while holding the lower end portion of the second wire 16, the second wire 16 is tensioned to prevent the slack. The spring 17 connects the lower end portion and one end portion of the tensioned second wire 16 in a state where a predetermined dimension is stretched from the natural length to which no external force is applied and an elastic force is generated to return to the original length. By being arranged in such a manner, a tensile force based on an elastic force is applied to the second wire 16, and the second wire 16 is maintained in a tensioned state without slack.

Further, when the mechanical unit 60 moves up or down by an external force applied to the kneading balls 61 such as when the back is placed on the backrest portion 93, the spring 17 is deformed to absorb the shock, and the wire It also has a function to prevent the wire from being pulled excessively, and the load on the wire can be reduced to increase the durability.
In addition, since the weight of the mechanical unit 60 is added to the upper first wire 15 as a load, it is naturally in tension without using any means for tension, and no slack is generated.

  The armrests 94 are located on both sides of the seat 92 and are integrally connected to the base 91. Even if the backrest 93 changes the reclining angle or the seat 92 tilts, the forearm of the user It is the structure formed so that it may be supported stably. The armrest portion 94 may also be configured so 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 95 is positioned on the front side of the seat portion 92 and is disposed to be tiltable about the vicinity of the front end of the seat portion 92, and the tilt angle is adjusted by a built-in actuator (not shown). The leg support portion 95 is provided with leg air cells 75 and 76 that operate by supplying and discharging air by the air pump 70.

  The remote controller 81 includes a large number of switches and display units for receiving various operation inputs to the massage machine, and is detachably installed on a stand 96 (see FIG. 1) on the side of the massage machine 90 to control the operation inputs related to the massage. This is transmitted to the unit 82. Note that the position of the stand 96 can be adjusted so that the position of the switch and the display unit of the remote controller 81 is the optimum position for the user.

  The control unit 82 adjusts the other movable parts of the treatment mechanism and the massage machine to the state corresponding to the user based on the remote control operation and the preset massage content, and also treats the treatment mechanism and other movable parts. Operation control for performing appropriate massage on the part is performed.

  The control unit 82 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 82 by a program stored in the memory or the like. The computer constituting the control unit 82 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 82 is disposed in a predetermined space inside the massage machine 90, such as directly below the seat 92, and is in a state where it can communicate with the remote controller 81 as shown in FIG. The unit 60, the actuators (not shown) of the backrest part 93 and the leg support part 95, and the air pump 70 are electrically connected to each other. When a massage is performed, a control signal output based on the set massage data is performed. These drive mechanisms are operated. Further, the control unit 82 is also electrically connected to signal output means such as an encoder that outputs the displacement amount of the mechanical unit 60 and each actuator, and the state of the mechanical unit 60 and the inclination of the backrest 93 and the leg support 95 are also described. These operation controls are performed while grasping the state of the above.

  Next, the operation of the treatment element moving mechanism of the massage machine according to the present embodiment will be described. As a premise, the main power of the massage machine 90 is turned on, the massage machine 90 is activated in a standby state, and the massage operation by each treatment mechanism is started upon receiving an operation state instruction input such as a massage course by the user. It shall be in

  When it is necessary to move the kneading balls 61 upward, the controller 82 drives the elevating motor 66 to rotate each drum in a predetermined direction, and the first drum 15 winds up the first wire 15 and the second drum. In 14, the second wire 16 is sent out, so that both drums are moved upward by the respective lengths of winding and sending out of each wire. As a result, the mechanical unit 60 that moves up and down integrally with the drums 13 and 14 also moves upward along the guide rails 11 and 12 and changes the position of the kneading balls 61 upward (see FIG. 7A). ).

  The rotation amount of each drum 13, 14 is obtained from the winding or feeding length of the wires 15, 16 corresponding to the vertical movement amount of the kneading balls 61 and the winding diameter of the wires 15, 16 on the drums 13, 14. It is rotationally driven so as to realize the given amount of movement.

  On the other hand, when it becomes necessary to move the kneading balls 61 downward, the control unit 82 drives the lifting motor 66 to rotate the drums in the opposite direction to the upper case, and the first drum 13 conversely to the above. Then, the first wire 15 is sent out, and the second drum 16 is taken up by the second drum 14, and both drums are moved downward by the lengths of the sending and winding of each wire. Accordingly, the mechanical unit 60 that moves up and down integrally with the drums 13 and 14 also moves downward along the guide rails 11 and 12 to change the position of the kneading balls 61 downward (see FIG. 7B).

  When it is not necessary to move the kneading balls 61 up and down, if the elevating motor 66 is stopped, the drums 13 and 14 do not rotate, the wire 15 is the weight of the mechanical unit, and the wire 16 is the spring 17. Since each of the wires 15 and 16 is in tension, the mechanical unit 60 can maintain the stopped state, and the kneading balls 61 also maintain their vertical positions.

  As described above, the treatment element moving mechanism of the massage machine according to the present embodiment arranges the mechanical unit 60 including the kneading balls 61 between the guide rails 11 and 12 of the backrest portion 93 so as to be movable in the vertical direction. The wires 15 and 16 are wound around the drums 13 and 14 disposed on the base portion 63 of the unit 60 and the ends of the wires 15 and 16 are held in the backrest portion 93, and the tension of the second wire 16 is maintained by the spring 17. The drums 13 and 14 are rotated while being secured, the wire winding state on the drum is changed, the drums 13 and 14 are moved, and the mechanical unit 60 integrated with the drums 13 and 14 is moved in the vertical direction. In addition, the wires 15 and 16 can support the weight of the mechanical unit 60 reliably and can be moved smoothly in the vertical direction. The cost can be greatly reduced by not using the gear mechanism to move up and down, so that the gear meshing noise is not generated, the quietness is enhanced, and the noise prevents the relaxing state by massage. Can be prevented. The two drums 13 and 14 and the wires 15 and 16 are used, and the ends of the wires 15 and 16 are fixed to the drums 13 and 14, and then the wires 15 and 16 are wound around the drums 13 and 14, and the mechanical unit. By preventing the wire 16 supporting 60 from being loosened by the spring 17, slipping between the drums 13 and 14 and the wires 15 and 16 wound around the drums 13 and 14 can be eliminated. The wires 15 and 16 are surely wound or sent out to be moved, the movement accuracy of the mechanical unit 60 can be improved, and the mechanical unit 60 can be moved without slipping between the drums 13 and 14 and the wires 15 and 16 even when the drum is stopped. The stop state can be maintained, and the reliability and safety of the moving operation and the treatment operation when stopped can be improved.

  In addition, in the treatment element moving mechanism of the massage machine according to the present embodiment, the spring 17 is used as the elastic body that forms the tension means. However, the present invention is not limited to this, and a structure using an elastomer such as rubber as the elastic body. As in the above-described embodiment, the second wire 16 is pulled downward by being interposed between the lower end portion of the second wire 16 and the lower frame 97b of the lower end portion of the backrest portion, so that the second wire 16 is loosened. The tension can be maintained without tension.

(Second embodiment of the present invention)
A massager moving mechanism of a massage machine according to a second embodiment of the present invention will be described with reference to FIGS.

In each of the drawings, the treatment element moving mechanism of the massage machine according to the present embodiment includes guide rails 21 and 22, a drum 23, and a wire 24, as in the first embodiment. And the wire 24 are respectively provided, the upper and lower ends of the wire 24 are respectively held by the upper and lower end portions of the backrest portion 93, and are wound around the drum 23 a predetermined number of times in the middle. As a means, a roller 25 that contacts the wire 24 and an elastic member 26 that presses the roller 25 against the wire 24 are provided.
In addition, the structure of each part other than the mechanism which concerns on raising / lowering of the mechanical unit 60 in the massage machine 90 is the same as that of the said 1st Embodiment, and abbreviate | omits description.

  As in the first embodiment, the guide rails 21 and 22 have a substantially U-shaped cross-sectional shape and a longitudinal shape along the surface of the backrest portion 93. As shown in FIG. The pair is fixed to the right frame 97c and the left frame 97d, and a pair is disposed on the left and right inside the backrest part.

  The guide rollers 68a, 68b, 68c, and 68d at the end of the mechanical unit 60 on the base 63 side are inserted into the guide rails 21 and 22, so that the entire mechanical unit 60 is paired with the pair of guide rails 21 and 22. The mechanism supported so as to be movable up and down along is also the same as in the first embodiment.

  The drum 23 is rotatably supported at a portion of the base 63 that does not overlap with the kneading balls 61 and the kneading balls driving unit 62 located in the center between the guide rails 21 and 22 (see FIG. 9). Driven by 66, rotates, moves relative to the wire as the wire 24 is wound and delivered, and simultaneously moves the entire mechanical unit 60 along the guide rails 21 and 22 above and below the backrest 93. The treatment site by the kneading balls 61 is changed up and down.

  The drum 23 changes the winding state of the wire 24 by the rotation of the lifting motor 66 and moves in the vertical direction with respect to the backrest portion 93. In any rotation direction, either the upper or lower side of the wire 24 is on the drum 23. It is pulled out and the other side of the wire is wound up.

  As shown in FIG. 11, one cylindrical groove 23a is provided in the cylindrical surface of the cylindrical drum around which the wire 24 is wound by the drum 23, and the wound wire 24 is provided in the groove 23a. Therefore, the wires 24 are not carelessly moved in the axial direction of the drum 23, and the wound wires 24 are aligned in the axial direction so that the wires 24 do not overlap each other.

  When the drum 23 is rotated to move the mechanical unit 60 up and down, the forces applied from the wire in each of the upward and downward movements are in opposite directions with respect to the center of the mechanical unit 60. Since moments are generated in different directions, in each direction of movement, the contact state of each guide roller 68a, 68b, 68c, 68d with the guide rails 21, 22 is made appropriate to alleviate excess force accompanying the moment, The smooth up and down movement is maintained.

  As shown in FIG. 8, the wire 24 is held by an upper frame 97 a positioned at the upper end portion inside the backrest portion 93, and the lower end frame positioned at the lower end portion inside the backrest portion 93. 97b, and the intermediate portion is wound around the drum 23. The drum position is held by wire tension when the drum 23 is stopped, and the vertical position of the mechanical unit 60 integrated with the drum 23 is maintained. On the other hand, when the drum 23 is rotated, the drum 23 is relatively moved in the vertical direction as the winding state of the drum 23 is changed, and the mechanical unit 60 is allowed to move up and down together with the drum. .

  As shown in FIGS. 9 and 10, the roller 25 is rotatably attached to a tip end portion of an arm 27 that is tiltably disposed on a base portion 63 of the mechanical unit 60. 21 and 22 is arranged so as to be movable and capable of contacting the lower portion of the wire 24 from the drum 23. The elastic member 26 presses the roller 25 against the wire 24 with an elastic force. Specifically, the arm 27 to which the roller 25 is attached is tilted in a direction in which the roller 24 presses the wire 24. It has become. As a result, the roller 25 can press the wire 24 based on the elastic force of the elastic member 26 and tension the wire 24 to prevent the slack. In addition to the spring, an elastomer such as rubber can be used for the elastic member 26.

  The roller 25 can move against the urging force of the elastic member 26 when the mechanical unit 60 moves up or down by an external force applied to the kneading balls 61 such as when the back is placed on the backrest 93. It also has the function of absorbing the impact and preventing the wire 24 from being pulled excessively, and the load on the wire 24 can be reduced to increase the durability.

  In addition, since the weight of the mechanical unit 60 is added as a load to the portion above the drum 23 of the wire 24, it is naturally in a tensioned state without using a tensioning means and does not loosen.

  Next, the operation of the treatment element moving mechanism of the massage machine according to the present embodiment will be described. As a premise, as in the first embodiment, it is assumed that the massage machine 90 is activated and a massage operation by each treatment mechanism is started upon receiving an instruction input from the user.

  When it is necessary to move the kneading balls 61 upward, the control unit 82 drives the elevating motor 66 to rotate the drum 23 in a predetermined direction, winds the portion of the wire 24 above the drum 23, and winds the wire 24. By feeding the portion below the drum 23, the drum 23 is moved upward on the winding side by the length of winding and feeding of the wire 24. As a result, the mechanical unit 60 that moves up and down integrally with the drum 23 also moves upward along the guide rails 21 and 22 and changes the position of the kneading balls 61 upward.

  The amount of rotation of the drum 23 is obtained from the winding and feeding length of the wire 24 corresponding to the vertical movement amount of the kneading balls 61 and the winding diameter of the wire 24 on the drum 23, as in the first embodiment. It is rotationally driven so as to realize the given amount of movement.

  On the other hand, when it becomes necessary to move the kneading balls 61 downward, the controller 82 drives the lifting motor 66 to rotate the drum 23 in the direction opposite to that in the upper direction. The upper part of the wire 24 is sent out, and the lower part of the wire 24 from the drum 23 is wound up, whereby the drum 23 is moved downward on the winding side by the length of the wire 24 taken up and sent out. . As a result, the mechanical unit 60 that moves up and down integrally with the drum 23 also moves downward along the guide rails 21 and 22 and changes the position of the kneading balls 61 downward.

  While the drum 23 rotates and moves upward or downward, the roller 25 and the elastic member 26 also move following the drum 23 together with the mechanical unit 60, and the roller 25 biased by the elastic member 26 moves the drum 25 in the wire 24. The portion below 23 is pressed in the vicinity of the drum 23 (see FIG. 10), and the wire 24 is tensioned to reliably suppress slippage between the drum 23 and the wire 24 and move the drum 23 by a desired amount of movement. Be made.

  When the drum 23 is rotated and the wire 24 is wound around the drum 23, the winding portion of the drum 23 is formed with a groove 23a. The wires wound while being maintained can be held in a non-overlapping state (see FIG. 11), the wire 24 can be smoothly wound and sent out, and the wires 24 on the winding body of the drum 23 can be wound together. The contact can be suppressed, the generation of noise such as frictional noise of the wire 24 can be prevented, and the moving mechanism can be made quiet.

  When there is no need to move the kneading balls 61 up and down, the drum 23 does not rotate and the wire 24 is pressed by the roller 25 as long as the elevating motor 66 is stopped as in the first embodiment. Since the tension of the upper portion and the lower portion of the wire 24 sandwiching the drum 23 is balanced, the mechanical unit 60 can maintain the stopped state and the kneading balls 61 also maintain the vertical position as it is. To do.

  Thus, in the treatment element moving mechanism of the massage machine according to the present embodiment, the only drum 23 around which the intermediate portion of the wire 24 stretched up and down is wound around the backrest portion 93 is used. When the winding body portion around which the wire 24 is wound is provided with the groove 23a and the wound wire 24 is set along the groove 23a, the winding number is sufficiently increased in order to ensure the friction between the drum 23 and the wire 24. However, the wound wires 24 do not come into contact with each other and do not overlap with each other, so that the wires 24 can be smoothly wound and sent out in response to the rotation of the drum 23, and even if only one drum 23 is used, it operates reliably. The mechanism relating to the movement of the mechanical unit 60 can be greatly simplified, and the movement mechanism can be reduced to the minimum necessary space, affecting other mechanisms of the massage machine. And no possible arrangement is made to correspond to massage machine of various shapes and applications by increasing the degree of freedom of the layout of each mechanism in the backrest portion 93.

  Note that in the treatment element moving mechanism of the massage machine according to the present embodiment, the roller 25 is brought into contact with the lower portion of the wire 24 from the drum 23 as the tensioning means, and the wire is moved by the roller 25 based on the elastic force of the elastic member 26. In addition to this, the wire 24 is tensioned by pressing the wire 24. In addition, as in the first embodiment, the elasticity of a spring or the like is provided between the lower end portion of the wire and the lower frame at the lower end portion inside the backrest portion. It can also be set as the structure which interposes a body.

(Third embodiment of the present invention)
A massager moving mechanism for a massage machine according to a third embodiment of the present invention will be described with reference to FIGS.
In each of the drawings, the treatment element moving mechanism of the massage machine according to the present embodiment includes guide rails 31 and 32, a drum 33, a wire 34, and a spring 35, as in the first embodiment. As shown in FIG. 1, only one drum 33 and one wire 34 are provided, and the upper and lower ends of the wire 34 are connected to the upper and lower ends (frames) in the backrest portion 93, respectively. Further, the guide rails 31 and 32 are formed in a circular tube shape, and the support form of the mechanical unit 60 by the guide rails 31 and 32 is different.
In addition, the structure of each part other than the mechanism which concerns on raising / lowering of the mechanical unit 60 in the massage machine 90 is the same as that of the said 1st Embodiment, and abbreviate | omits description.

  The guide rails 31 and 32 are circular tubular bodies having a substantially circular cross-sectional shape, and are formed in a longitudinal direction along the surface of the backrest portion 93 in accordance with the shape of the back of a person. Both ends are fixed to an upper frame 97a and a lower frame 97b inside the backrest portion 93, respectively, and a pair is arranged on the left and right inside the backrest portion so as to be narrower than the distance between the left and right frames 97c, 97d. The distance between the pair of guide rails 31 and 32 is narrower than the entire width of the mechanical unit 60.

  On the other hand, guide rollers 69a, 69b, 69c, 69d, 69e, 69f, 69g, and 69h are rotatably attached to the base portion 63 of the mechanical unit 60 (see FIGS. 13 and 14). Each of the guide rollers 69a, 69b, 69c, 69d, 69e, 69f, 69g, and 69h is arranged so as to sandwich the guide rails 31 and 32 in pairs, and more specifically, between the guide rollers 69a and 69b and the guides The guide rail 31 is sandwiched between the rollers 69c and 69d (see FIG. 15), while the guide rail 32 is sandwiched between the guide rollers 69e and 69f and between the guide rollers 69g and 69h. By rolling along the guide rails 31 and 32, movements other than moving in the longitudinal direction of the guide rails 31 and 32 are restricted, so that the entire mechanical unit 60 moves up and down along the pair of guide rails 31 and 32. It is a mechanism that is supported so as to be movable.

  The mechanical unit 60 is provided with guide rollers 69a, 69b, 69c, 69d, 69e, 69f, 69g, and 69h that are in contact with the guide rails 31 and 32, and has a base 63 shape corresponding to the arrangement of the guide rollers. Except for the points adopted, the configuration is the same as that of the first and second embodiments, and detailed description thereof is omitted.

  As in the second embodiment, the drum 33 is fixed and supported so as to be rotatable at a position off the center between the guide rails 31 and 32 in the base portion 63, and is driven and rotated by a lifting motor 66. As the wire 34 is wound and delivered, the wire 34 moves relative to the wire, and at the same time, the entire mechanical unit 60 is moved up and down the backrest 93 along the guide rails 31 and 32. Is omitted. In addition, the cylindrical surface winding drum portion around which the wire 34 is wound by the drum 33 has a configuration in which a spiral continuous groove is provided as in the second embodiment.

  When the mechanical unit 60 is moved up and down by rotating the drum 33, a force applied relatively from the wire 34 acts on the drum 33 away from the center of the mechanical unit 60, so that a moment is applied to the mechanical unit 60. However, since the interval between the guide rails 31 and 32 is narrowed, the guide rollers 69a, 69b, 69c, 69d, 69e, 69f, 69g, and 69h on the guide rollers 31 that are in contact with the guide rails 31 and 32 are arranged. The moment of movement is small, and each guide roller can be smoothly moved on the guide rails 31 and 32, so that the vertical movement of the mechanical unit 60 is not affected by stagnation or the like.

  As in the second embodiment, one end of the wire 34 is held by the upper frame 97a located at the upper end inside the backrest 93, and the other end is located at the lower end inside the backrest 93. It is configured to be held by the lower frame 97b and disposed so that the intermediate portion is wound around the drum 33 (see FIG. 12).

  As shown in FIG. 12, the spring 35 is disposed between the lower end portion of the wire 34 and the lower frame 97b of the lower end portion of the backrest portion 93 as tensioning means. By pulling on the wire 34, the wire 34 is tensioned to prevent the slack.

  When the mechanical unit 60 moves up or down by an external force applied to the kneading balls 61 such as when the back is placed on the backrest portion 93, the spring 35 is deformed to absorb the shock, and the wire 34 Has a function of preventing the wire from being pulled excessively, and the load on the wire 34 can be reduced to increase durability.

  In addition, since the weight of the mechanical unit 60 is applied as a load to the upper part of the wire 34 from the drum 33, the wire 34 is in a naturally tensioned state without using any tensioning means and does not loosen.

  Next, the operation of the treatment element moving mechanism of the massage machine according to the present embodiment will be described. As a premise, as in the first embodiment, it is assumed that the massage machine 90 is activated and a massage operation by each treatment mechanism is started upon receiving an instruction input from the user.

  When it is necessary to move the kneading balls 61 upward, the control unit 82 drives the elevating motor 66 to rotate the drum 33 in a predetermined direction, winds the portion of the wire 34 above the drum 33, and winds the wire 34. By feeding the lower portion of the drum 33, the drum 33 is moved upward by the length of winding and feeding of the wire 34. As a result, the mechanical unit 60 that moves up and down integrally with the drum 33 also moves upward along the guide rails 31 and 32 and changes the position of the kneading balls 61 upward.

  The rotation amount of the drum 33 is obtained from the winding and feeding length of the wire 34 corresponding to the vertical movement amount of the kneading balls 61 and the winding diameter of the wire 34 in the drum 33, as in the first embodiment. It is rotationally driven so as to realize the given amount of movement.

  On the other hand, when it is necessary to move the kneading balls 61 downward, the controller 82 drives the lifting motor 66 to rotate the drum 33 in the direction opposite to that in the upper direction. The portion above the wire 33 is fed out, and the portion below the drum 33 of the wire 34 is wound, whereby the drum 33 is moved downward by the length of the wire 34 wound and fed. As a result, the mechanical unit 60 that moves up and down integrally with the drum 33 also moves downward along the guide rails 31 and 32 and changes the position of the kneading balls 61 downward.

  When the drum 33 is rotated and the wire 34 is wound around the drum 33, since the groove is formed in the winding drum portion of the drum 33, the wire 34 is wound in the aligned state and the aligned state is maintained. The wound wires can be held in a non-overlapping state, the wires 34 can be smoothly wound and sent out, and contact between the wires 34 on the winding drum portion of the drum 33 can be suppressed, so that the wires 34 Generation of noise such as frictional noise can be prevented.

  When there is no need to move the kneading balls 61 up and down, the drum 33 does not rotate as long as the elevating motor 66 is stopped as in the first embodiment. Is the weight of the mechanical unit 60, and the lower part of the wire 34 from the drum 33 is urged by the spring 35 and is in tension, and the tension of the upper part and the lower part of the wire 34 sandwiching the drum 33 is balanced. Therefore, the mechanical unit 60 can hold the stopped state, and the kneading balls 61 also maintain the same vertical position.

  As described above, in the treatment element moving mechanism of the massage machine according to the present embodiment, one drum 33 around which the wire 34 is wound in the backrest portion 93 is used, and a groove is provided in the winding drum portion of the drum 33. Since the wound wire 34 runs along the groove, even when the number of times of winding the wire around the drum is increased, the wires 34 do not come into contact with each other and do not overlap each other. Even if only one 33 is used, the friction between the drum 33 and the wire 34 can be appropriately secured to ensure the moving operation of the mechanical unit 60, and the mechanism related to the moving of the mechanical unit 60 is greatly simplified and saved. Space can be made. Further, by arranging the gap between the pair of guide rails 31 and 32 to be narrower than the width of the mechanical unit 60, the mechanical unit 60 caused by the moment generated when the mechanical unit 60 moves can be caused to fluctuate on the guide rails 31 and 32. The adverse effect of rattling can be mitigated, and the mechanical unit 60 can be reliably moved along the guide rails 31 and 32.

(Fourth embodiment of the present invention)
A massager moving mechanism for a massage machine according to a fourth embodiment of the present invention will be described with reference to FIGS.
In each of the drawings, the treatment element moving mechanism of the massage machine according to this embodiment is similar to the first embodiment, like the first embodiment, the guide rails 41 and 42, the drums 43 and 44, the wire 45, 46 and springs 47 and 48, but the difference is that the drums 43 and 44 are disposed at the base 63 side end of the mechanical unit 60, and the wires 45 and 46 have upper and lower ends at the guide rails 41 and 42, respectively. A configuration in which the upper and lower ends are connected to each other along the inner peripheral surfaces of the guide rails 41 and 42 having a substantially U-shaped cross section, and the drums 43 and 44 are also arranged to pass through the guide rails 41 and 42, respectively. It is what has.
In addition, the structure of each part other than the mechanism which concerns on raising / lowering of the mechanical unit 60 in the massage machine 90 is the same as that of the said 1st Embodiment, and abbreviate | omits description.

  Like the first embodiment, the guide rails 41 and 42 have a substantially U-shaped cross-sectional shape and a longitudinal shape along the surface of the backrest portion 93, and the right frame 97 c and the left frame inside the backrest portion 93. Each pair is fixed to 97d (see FIG. 16), and a pair is disposed on the left and right inside the backrest portion.

  On the other hand, as shown in FIGS. 16 to 18, two drums 43 and 44 are rotatably supported at the edge of the base portion 63 of the mechanical unit 60, and the guide rails 41 and 42 serve as guide rollers. Rolls in contact with the inner peripheral surface. Further, guide rollers 68e and 68f are also rotatably attached to the end edge portion of the same base portion 63 (see FIGS. 16 and 17). The drums 43 and 44 and the rollers 68e and 68f are inserted into the guide rails 41 and 42, abut against the inner peripheral surfaces of the guide rails 41 and 42, respectively, and roll along the guide rails 41 and 42. 42, the movement other than the movement in the longitudinal direction is restricted, whereby the entire mechanical unit 60 is supported so as to be movable up and down along the pair of guide rails 41 and 42.

  The mechanical unit 60 has the same configuration as that of the first embodiment except that the drums 43 and 44 and the guide rollers 68e and 68f contacting the guide rails 41 and 42 are disposed. The detailed explanation is omitted.

  The drums 43 and 44 include a first drum 43 that is inserted and disposed on one guide rail 41 in a state in which one wire 45 is wound, and the other in a state in which the other wire 46 is wound. The second drum 44 is inserted into the guide rail 42 and is fixedly supported at the edge of the base 63 so as to be rotatable. The second drum 44 is driven by a lifting motor 66 and rotated. 46 is wound relative to the wire as it is wound and delivered, and at the same time, the entire integrated mechanical unit 60 is moved up and down the backrest 93 along the guide rails 41, 42, so Is changed up and down.

  The drums 43 and 44 also serve as guide rollers that contact the guide rails 41 and 42 to guide the vertical movement of the mechanical unit 60, and can be rotated independently of the drum body of the drum. The large-diameter outer peripheral portion rolls in contact with the inner peripheral surfaces of the guide rails 41 and 42 as the guide roller (see FIG. 18), and the movement is limited only within the guide rail.

  The first drum 43 and the second drum 44 have the same shape, are arranged on the same drive shaft, and are simultaneously driven to rotate in the same rotational direction by the lifting motor 66, so that the winding state of the wires 45 and 46 is changed. The same is moved in the vertical direction with respect to the backrest portion 93, and the vertical position of the mechanical unit 60 is simultaneously changed. In any rotation direction, the upper and lower sides of the wires 45 and 46 are drawn on the drums 43 and 44, and the other side of the wires 45 and 46 is wound.

  The wires 45, 46 are held at one end on the upper part of one guide rail 41, the other end is held at the lower part of the same guide rail 41, and an intermediate part is wound around the first drum 43. A first wire 45 disposed along a back surface 41a (see FIG. 18) facing the opposite side of the inner peripheral surface of the guide rail 41 with respect to the surface contacting the back of the backrest portion 93; One end is held on the upper part of the other guide rail 42, the other end is held on the lower part of the same guide rail 42, and the intermediate part is wound around the second drum 44. Of the inner circumferential surface, the second wire 46 is disposed along the back surface 42a (see FIG. 18) facing the opposite side to the surface of the backrest 93 that contacts the back. When the rotation stops, the wire tension While maintaining the ram position and maintaining the vertical position of the mechanical unit 60 integral with the drums 43, 44, the drums 43, 44 are rotated as the winding state of the drums 43, 44 is changed. 44 is relatively moved in the vertical direction, and the mechanical unit 60 is allowed to move up and down together with each drum.

  As shown in FIG. 16, the springs 47, 48 are disposed between the lower end portion of the first wire 45 and the lower portion of the guide rail 41, the lower end portion of the second wire 46, and the guide. The second spring 48 is disposed between the lower portion of the rail 42 and is disposed as an elastic body that serves as a tension means while holding the lower ends of the first wire 45 and the second wire 46. , 46 are pulled downward to tension the wires 45, 46 and prevent their loosening. As in the first embodiment, each of the springs 47 and 48 is stretched by a predetermined length from a natural length to which no external force is applied, and a tensioned wire is generated in a state where an elastic force is generated to return to the original length. A state in which the lower ends of the wires 45 and 46 are connected to each other to provide a tensile force based on the elastic force to the wires 45 and 46, and the wires 45 and 46 are stretched without slack. It is a mechanism to maintain.

  Next, the operation of the treatment element moving mechanism of the massage machine according to the present embodiment will be described. As a premise, as in the first embodiment, it is assumed that the massage machine 90 is activated and a massage operation by each treatment mechanism is started upon receiving an instruction input from the user.

  When it is necessary to move the kneading balls 61 upward, the controller 82 drives the elevating motor 66 to rotate the drums 43 and 44 in a predetermined direction. By winding up the upper portion and sending out the lower portion of the first wire 45 from the drum, the first drum 43 is wound in the guide rail 41 by the length of the winding and sending of the first wire 45. Move upward. At the same time, in the second drum 44, the upper portion of the second wire 46 is wound up and the lower portion of the second wire 46 is sent out, so that the second drum 44 is wound around the second wire 46. It is moved upward in the guide rail 42 by the length of the take-up and delivery. In this way, both drums having the same shape can be moved upward by the same movement amount, and the mechanical unit 60 that moves up and down integrally with the drums 43 and 44 also moves upward along the guide rails 41 and 42, and stagnation. The position of the ball 61 is changed upward (see FIG. 19A).

  As with the first embodiment, the amount of rotation of each of the drums 43 and 44 depends on the winding or feeding length of the wires 45 and 46 corresponding to the amount of vertical movement of the kneading balls 61 and the wires 45 and 46 in the drums 43 and 44. The elevating motor 66 is rotationally driven so as to realize a given amount of movement.

  On the other hand, when it is necessary to move the kneading balls 61 downward, the control unit 82 drives the lifting motor 66 to rotate the drums 43 and 44 in the opposite direction to the upper case, and the first is opposite to the above. In one drum 43, the upper portion of the first wire 45 from the drum 43 is sent out, and the lower portion of the first wire 45 from the drum 43 is wound up, so that the first drum 43 is sent out and It is moved downward in the guide rail 41 by the length of each winding. At the same time, in the second drum 44, the upper part of the second wire 46 from the drum 44 is sent out, and the lower part of the second wire 46 from the drum 44 is wound up, whereby the second drum 44 is taken up by the second wire 46. Is moved downward in the guide rail 42 by the length of each of the feeding and winding. In this way, both drums can be moved downward by the same amount of movement, and the mechanical unit 60 that moves up and down integrally with the drums 43 and 44 also moves downward along the guide rails 41 and 42, and the position of the kneading balls 61 is changed. It is changed downward (see FIG. 19B).

  When the drums 43 and 44 move, the first drum 43 moves on the inner surface of the guide rail 41 and the second drum 44 moves on the inner surface of the guide rail 42 while rolling as a guide roller. Together with the rollers 68e and 68f, it plays a role of guiding the mechanical unit 60 so that unnecessary movement does not occur.

  In addition, while the drums 43 and 44 are moving, the upper and lower portions of the wires 45 and 46 that are in tension are sandwiched between the upper and lower ends of the wires and the length of each wire between the drums is minimized. However, since the wires 45 and 46 are accommodated in the guide rails 41 and 42, the guide rails 41 and 42 are guided by the restraint by the back side surfaces 41a and 42a. The members 45 and 46 are not physically separated from the rails 41 and 42, and the members 45, 46 are physically connected to the members inside the backrest portion 93, particularly the members positioned on the surface side of the backrest portion 93 relative to the guide rails 41 and 42. It is not necessary to take into account dynamic interference (see FIG. 19).

  When it is not necessary to move the vertical position of the kneading balls 61, the drums 43 and 44 do not rotate as long as the elevating motor 66 is stopped as in the first embodiment. The upper part of the first drum 43 is the weight of the mechanical unit 60, and the lower part of the first wire 45 from the first drum 43 is biased by the first spring 47. In addition to the tension of the upper part and the lower part sandwiching one drum 43 being balanced, the upper part of the second wire 46 from the second drum 44 is the weight of the mechanical unit 60, and the second wire 46 has a second weight. The lower part of the drum 44 is urged by the second spring 48 and is in a tension state, and the tension of the upper part and the lower part of the second wire 46 sandwiching the second drum 44 is also balanced. Mechanical unit 60 Can maintain the stopped state, the kneading balls 61 also maintains intact vertical position.

  As described above, in the treatment element moving mechanism of the massage machine according to the present embodiment, the wires 45 and 46 are arranged along the predetermined surfaces 41a and 42a of the guide rails 41 and 42, and the wires 45 and 46 are arranged. Drums 43 and 44 are also arranged in the vicinity of the guide rails 41 and 42. While the drums 43 and 44 are rotated to change the winding state of the wires 45 and 46, each wire to be displaced according to the drum position. Since 45 and 46 are restrained by the guide rails 41 and 42, respectively, the state where the wires 45 and 46 are present in the vicinity of the guide rails 41 and 42 can be maintained regardless of the position of the mechanical unit 60, and the backrest of the wires 45 and 46 is maintained. The portion between the end held inside the portion 93 and the portion wound around the drums 43 and 44 becomes a straight line due to tension, and the guide lever The wire 45, 46 and other members inside the backrest 93 can be prevented from being physically interfered with at any position of the mechanical unit 60. 45 and 46 can be easily built in the backrest portion 93 and the mechanical unit 60 can be smoothly moved up and down.

  In addition, in the treatment element moving mechanism of the massage machine according to the embodiment, the wires 45 and 46 are accommodated in the guide rails 41 and 42, and the wires 45 and 46 reach positions away from the guide rails 41 and 42. In addition to this, as shown in FIG. 20, instead of the wire being housed in the guide rail, the drum 53 is arranged against the wire 55 that is exposed to the outside of the guide rail 51. The wire guide 57 is pressed with the drum 53 at a position away from the wire guide 57 to prevent the tensioning wire 55 from jumping to the side closer to the user's back than the guide rail 51. It can also be configured to be disposed in the mechanical unit 60 such as the base portion 63 as possible, and as in the above-described embodiment, the physical relationship between each member inside the backrest portion 93 and the wire 55 Finished without considering the interference, it can increase the flexibility of the layout of each member in the backrest.
