Description

  The present invention relates to a massage machine capable of giving a massage to a treatment element, and more particularly, to a massage machine which obtains a massage by shaking a treatment element left and right using a tilting shaft driven to rotate. is there.

  2. Description of the Related Art There is known a massage machine that draws a trajectory in which a massager can obtain a massage using a rotationally driven tilt axis.

  The above-mentioned fir massage is a treatment element that draws an elliptical locus that fits in a 40 mm square. In this case, if the treatment element comes into contact with the acupoint (tenderness point), it feels comfortable. When it comes off, especially when it comes into contact with bones, it feels unpleasant pain.

  On the other hand, there is a technique called “acupuncture” that is frequently used in massage treatment. As shown in FIG. 8, this is a massage that moves the vicinity of the wrist circularly or linearly while pressing the human body with the thumb or palm as a support point (support surface). With this acupuncture massager, the treatment element will do almost “scrubbing exercise” centering on the contact point with the human body, so it will not hit the bones, and therefore it will not feel uncomfortable pain Absent.

  Then, the present inventors have found that if the therapeutic element is moved to draw a circular trajectory within a 20 mm square, a massage operation that can provide a sense equivalent to the acupuncture massage can be obtained. . That is, when a treatment element of the same size as a thumb is moved to draw a circular trajectory in a 20 mm square, the treatment element itself does not perform a surging motion. It was found that if the movement of drawing a circular trajectory within the range of is performed, it becomes the same massage as the acupuncture massage.

The acupuncture massage operation that draws a circular trajectory within a 20 mm square can be obtained by appropriately setting the inclination angle of the inclination axis and the length from the inclination axis to the treatment element even in the case of using the inclination axis. Can do. However, if the setting is made in this way, the normal massage treatment can not be obtained.

  The present invention was invented in view of the above-mentioned conventional problems, and in the case where a massager is allowed to perform a massage operation using an inclined axis, both the acupuncture massage and the massage massage can be selectively obtained. It is an object to provide a massage machine that can be used.

  In order to solve the above problems, a massage machine according to the present invention includes a drive shaft that is rotationally driven, an inclined shaft that is provided on the drive shaft with a shaft that is inclined with respect to the drive shaft, and an outer peripheral surface of the inclined shaft. The movement of the treatment element due to the rotation of the drive shaft is controlled in a 20 mm square by restricting the movement of the swinging arm provided with the treatment element and the swinging arm including the treatment element in accordance with the rotation of the inclined shaft. It is a massage machine that moves in a circular locus, and is provided with a driving means for changing the position of the treatment element, and is synchronized with an operation for drawing the locus of the treatment element by the rotation of the drive shaft. And a control unit that operates the driving means to change the trajectory. When only the drive shaft is rotated, the treatment element can obtain an acupuncture massage operation that draws a circular trajectory in a 20 mm square, and is driven by synchronizing the drive means for changing the position of the treatment element If you do this, you can get a massage even if the range of movement of the treatment element expands.

  The above-mentioned control unit can be suitably used by superimposing a movement of reciprocating the vertical position of the treatment element up and down once on a movement of drawing a circular trajectory of the treatment element by the rotation of the drive shaft.

  The present invention is to allow a treatment element to perform a massage operation using an inclination axis, and the movement of the treatment element is almost determined by the inclination of the inclination axis. In addition to the movement of drawing a circular trajectory in a 20 mm square, which is the same sensation of massage, the movement of a normal fir massage operation can be obtained.

  Hereinafter, the present invention will be described based on an embodiment shown in the accompanying drawings. The massage mechanism shown in FIG. 2 is arranged so as to freely run up and down in the back of the chair, and the vertical frames 11 and 11 positioned on the left and right. And a frame 1 composed of a guide shaft 13 for connecting the upper ends of the vertical frames 11 and 11 and a pair of mounting plates 14 and 14 arranged in the middle of the left and right sides. The unit 3 and the hitting drive motor unit 4 and a pair of left and right treatment element blocks 5 and 5 are mounted.

  The traveling shaft 30 installed between the lower ends of the vertical frames 11 and 11 has pinions 31 fixed to both ends thereof, and guide rollers 32 and 33 are rotatably mounted thereon. Guide rollers 32 are provided at both ends. These guide rollers 32 roll in guide rails arranged on the left and right sides of the backrest, and the pinion 31 meshes with a rack attached to the guide rails. For this reason, when the vertical drive motor unit 3 rotationally drives the travel shaft 30 provided with the pinion 31, the massage mechanism 1 self-travels up and down in the backrest along the guide rail.

  The rotation of the kneading drive motor unit 2 is transmitted to the drive shaft 20 disposed below the mounting plates 14 and 14. The drive shaft 20 includes eccentric shaft portions 21 and 21 at both ends thereof, and an inclined shaft in which the central axis of the outer peripheral surface is inclined with respect to the axis of the drive shaft 20 on the outer periphery of each eccentric shaft portion 21. The treatment element blocks 5 and 5 are connected to the two inclined shafts 22 and 22 that rotate together with the drive shaft 20, respectively.

  The treatment element block 5 includes a swing arm 51 whose one end is connected to the outer periphery of the inclined shaft 22 via a bearing 54 and a support arm whose central portion is pivotally supported on the other end of the swing arm 51. 52, and roller-shaped treatment elements 50 and 50 that are pivotally supported at both upper and lower ends of the support arm 52 having a square side shape. The support arm 52 has the upper treatment element 50 in front of the backrest. It is attached to the swing arm 51 so as to be pivotable up and down by a shaft 53 in a state where it is spring-biased in a direction protruding to the side.

  A hitting drive shaft 40 driven by the hitting drive motor unit 4 via the belt 43 is installed on the upper part of the mounting plates 14 and 14. The hitting drive shaft 40 is formed as a crankshaft having eccentric shaft portions at both ends, and a connecting rod 45 is provided between each eccentric shaft portion and the swing arm 51 of each of the treatment element blocks 5. It is connected. The connecting rod 45 and the swing arm 51 are connected by a joint that can freely move in three dimensions, and the rotation of the drive shaft 40 between the connecting rod 45 and the drive shaft 40 can be freely rotated. In addition, the connecting rod 45 is connected so that it can freely swing in the axial direction of the drive shaft 40.

  Then, as described above, the massage mechanism 1 is self-propelled up and down in the backrest by driving the vertical drive motor unit 3 and changes the position of the treatment element 50 up and down. At this time, since the support arm 52 including the upper and lower two treatment elements 50 and 50 is connected to the swing arm 51 so as to be pivotable up and down and is spring-biased, the two upper and lower treatment elements 50 are provided. , 50 can always be in contact with the back of the human body held by the backrest.

  In addition, when the kneading drive motor unit 2 is rotated, the tilt shafts 22 and 22 respectively disposed on the eccentric shaft portions 21 and 21 at both ends of the drive shaft 20 are opposite to each other. The left and right treatment element units 5 and 5, in which the swing arm 51 is mounted on the outer periphery of each inclined shaft 22 and 22 and the movement of the swing arm 51 is restricted by the connecting rods 45 and 45, approach each other. The upper and lower treatment elements 50 and 50 are caused to move away from each other. At this time, the eccentric shaft portion 21 to which the inclined shaft 22 is attached is eccentric, and the treatment element 50 is also moved forward and backward. Move.

  Here, because of the eccentric component and the tilt component, the movement of the treatment element 50 when the drive shaft 20 is rotated draws a three-dimensional circular trajectory in the front-rear, left-right, up-down directions. Then, by appropriately setting the eccentric component, the tilt component, and the length of the swing arm 51, the circular locus drawn by the treatment element 50 is set within a 20 mm square.

  If a treatment element of the same size as an acupuncture finger is moved to draw a circular trajectory in a 20 mm square, a massage with the same sensation as the acupuncture massage will be performed as described above. Can be obtained.

  As shown in FIG. 7, the muscles on the shoulder side near the scapula K of the human body run diagonally, and the muscles on the spine side run in the vertical direction. Since the motion of drawing includes a motion component in a direction orthogonal to these muscle bundles, the muscle can be surely loosened, and the width of the muscle bundle is 5 to 10 mm. Alternatively, the muscle bundle can be shaken as long as the treatment element is moved within a narrower range, and the treatment element 50 does not hit the bone. In addition, although the operation | movement which moves the treatment element 50 in the larger range, for example, 40 mm square, is effective in the point of stiffening a shoulder muscle, if it is performed in said position, there exists a possibility that the treatment element 50 may hit a bone. In addition to being high, it is a different sensation from acupuncture massage for the patient.

  In the massage machine according to the present invention, as shown in FIG. 1, a single reciprocation operation β in the vertical direction is performed by synchronizing the vertical movement with the acupuncture massage movement α obtained by rotating the drive shaft 20. By superimposing, a vertical elliptical trajectory α + β having a vertical direction of 20 mm or more can be drawn on the treatment element 50 so that a normal massage operation can be performed.

  That is, 73 in FIG. 2 is a slit disk for detecting the vertical position, and by detecting a plurality of types of slits S1, S2, S3 provided in the slit disk 73 with the photosensor 74, for example, FIG. As shown, the vertical position of the treatment element 50 can be detected, and whether the vertical drive motor unit 3 is moving upward or downward from the rotational direction can be detected. As shown in FIG. 5, in the acupuncture massage operation by the rotation of the drive shaft 20 by the slits S4 and S5 of the slit disk attached to the drive shaft 20 that is rotationally driven by the drive motor unit 2, and the photo sensor. It is possible to detect which position of the circular locus is detected and at the same time, which direction it is moving from the rotation direction of the kneading drive motor unit 2. It is.

  In a control circuit (not shown) for controlling the driving of the motor units 2, 3 and 4, only the driving shaft 20 is rotated when an acupuncture massage is instructed, but a wider range of movement is treated. When an instruction is given to the child 50, the drive shaft 20 is rotated using the detection output, and at the same time, the vertical drive motor unit 3 is driven to move up and down in synchronization with the movement of the treatment element 50. By doing so, the vertical component of the movement of the treatment element 50 is expanded vertically by the above vertical movement, and the locus of the ellipse is drawn on the treatment element 50.

  The massage mechanism of the illustrated example does not have a function of adjusting the distance between the pair of left and right treatment element units 5 and 5, but in the case of having this function, the left and right direction by the distance adjustment function is used for the acupuncture massage operation. 4, a horizontally long elliptical trajectory having a horizontal direction of 20 mm or more can be drawn on the treatment element 50 as shown in FIG. By synchronizing with the acupuncture massage operation, it is possible to draw a circular trajectory of 20 mm or more in the vertical and horizontal directions on the treatment element 50.

  In the case where the inclination angle of the inclination shaft 22 is set so that the treatment element 50 draws a circular locus that does not fit within a 20 mm square by the rotation of the drive shaft 20, the vertical movement operation and the interval adjustment function It is also possible to draw a circular trajectory in which the treatment element 50 fits in a 20 mm square by overlapping the movements synchronously.

  As shown in FIG. 5, the support arm 52 provided with the treatment elements 50, 50 is composed of two pieces 52a, 52b, and the interval between the treatment elements 50, 50 arranged vertically is determined by the rotation of the support arms 52a, 52b. If the support arms 52a and 52b are connected by a tension spring 53, the upper and lower treatment elements 50 and 50 can escape upward and downward, respectively, when the treatment element 50 comes into contact with the human body. This changes the circular trajectory of the treatment element 50 into a vertically long trajectory.

  Then, if the drive shaft 20 is driven in a state where the human body is strongly pressed against the treatment element 50, the support arms 52a and 52b are spread and a circular trajectory is drawn in a square of 20 mm square to massage the human body. However, when the human body is lightly pressed against the treatment element 50, the distance between the support arms 52a and 52b changes according to the change in the contact pressure between the treatment element 50 and the human body accompanying the movement of the treatment element 50. At this time, it will draw a long trajectory and it will be a soft massage.
