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. 6, this is a massage that moves the vicinity of the wrist circularly or linearly while pressing the human body using 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 has been invented in view of the above-described conventional problems, and is a massage machine capable of obtaining an acupuncture massage in addition to a fir tree massage in a treatment element that performs a massage operation using an inclined axis. It is a problem to provide.

  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. A swivel arm connected to the swivel and a restricting member for restricting the movement of the swivel arm provided with the treatment element in accordance with the rotation of the inclined shaft, and the massage element is also operated for massaging. In the massage machine that performs the movement of drawing the locus by the rotation of the driver element, driving means for causing the treatment element to perform the movement for acupuncture massage that draws a circular locus in a square of 20 mm square is provided separately from the drive shaft. It is characterized in that it is provided as driven.

  Acupuncture massage can be obtained by operating the driving means, and both firri massage and acupuncture massage can be obtained simultaneously.

  In the case where the driving means is attached to the swing arm, the massager can perform a massage operation in which the movement of the acupuncture massage is superimposed on the movement of the fir massage.

  The present invention not only allows the treatment element to perform massage operation using the tilt axis, but also allows the treatment element to perform acupuncture massage operation by the driving means for acupuncture massage, A massage according to the application can be appropriately obtained.

  Hereinafter, the present invention will be described with reference to the embodiments shown in the accompanying drawings. FIG. 1 and FIG. 2 show a massage mechanism that is arranged so as to be capable of self-propelled vertically in a backrest, and is a vertical frame located on the left and right. 11 and 11, a frame 1 composed of a guide shaft 13 connecting the upper ends of the vertical frames 11 and 11, a pair of mounting plates 14 and 14 arranged in the middle of the left and right, etc. The upper and lower drive motor unit 3, the hitting drive motor unit 4, and a pair of left and right treatment element blocks 5, 5 are mounted.

  Pinions 31 are fixed to both ends of the running shaft that is installed between the lower ends of the vertical frames 11 and 11, and guide rollers 32 and 33 are mounted so as to be freely rotatable. The guide shaft 13 is also attached to both ends. Guide rollers 32 are provided. The 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 traveling shaft provided with the pinion 31, the massage mechanism 1 self-propels in the backrest along the guide rail. Reference numeral 73 in FIG. 2 denotes a slit disk, which detects the vertical position of the self-propelled massage mechanism in combination with a photosensor 74 for detecting a plurality of types of slits provided on the slit disk 73.

  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 attached to the upper and lower ends of the support arm 52 having a side shape, and the support arm 52 has the upper treatment element 50 on the front side of the backrest. A spring 53 is spring-biased in the protruding direction and is attached to the swing arm 51 so as to be rotatable up and down by a shaft 53.

  Further, the treatment element 50 located on the lower end side of the support arm 52 is merely free to swing around its axis, whereas the treatment element 50 located on the upper end side of the support arm 52 is Instead of being attached directly to the support arm 52, it is attached to the support arm 52 via the saddle drive unit 6.

  As shown in FIG. 3, the scissors drive unit 6 includes a motor 60 fixed to the support arm 52, an eccentric shaft portion 62 provided on the output shaft of the motor 60, and a support plate that supports the roller-shaped treatment element 50. 61, the support plate 61 is attached to the eccentric shaft portion 62, and when the motor 60 is rotated, the treatment element 50 draws a circular locus having a diameter corresponding to the eccentric amount of the eccentric shaft portion 62. Note that the support plate 61 may be attached to the eccentric shaft portion 62 so as to rotate together, or the support plate 61 may be rotatable around the axis of the eccentric shaft portion 62.

  Here, since the eccentric amount of the eccentric shaft portion 62 with respect to the output shaft of the motor 60 is set to 10 mm or less, the circular locus drawn by the treatment element 50 has a diameter of 20 mm or less.

  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. At this time, 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 about the axis between the connection rod 45 and the drive shaft 40 is performed. The connecting rod 45 is connected so that it can freely swing in the axial direction of the drive shaft 40.

  As described above, the massage mechanism 1 self-propels up and down in the backrest by driving the vertical drive motor unit 3 to change the position of the treatment element 50 up and down. At this time, the support arm 52 including the upper and lower treatment elements 50 and 50 is connected to the swing arm 51 so as to be rotatable up and down and is spring-biased as described above. It is possible to obtain a state where the two treatment elements 50, 50 are always 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. This three-dimensional movement in the front-rear, left-right, up-down directions is a movement for fir massage in the above-mentioned conventional example, and for example, draws an elliptical locus that fits in a square of about 40 mm square.

  On the other hand, when the scissors drive motor unit 2 is operated with the paddle drive motor unit 2 stopped, the upper treatment element 50 has a circular locus that fits in a 20 mm square as described above. 50.

  If a treatment element 50 of the same size as an acupuncture finger is moved to draw a circular trajectory in a 20 mm square, the same feeling as that of the acupuncture massage is given to the user as described above. A massage can be obtained.

  As shown in FIG. 5, 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. ) Includes a movement component in a direction perpendicular to these muscle bundles, so that the muscles can be reliably loosened, and the width of the muscle bundles is 5 to 10 mm. The muscle bundle can be shaken by the amount of movement of the treatment element within four or narrower ranges, and at the same time, 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 example shown in the embodiment, if the heel drive unit 2 is also activated when the massage operation is obtained by rotating the drive shaft 20, the heel massage operation is superimposed on the massage operation. It is also possible to cause the treatment element 50 to perform the movement. In this case, since the point where acupuncture massage is performed is shifted by the fir massage operation, it is possible to perform acupuncture massage without adjusting the position with respect to many points. Of course, the acupuncture massage operation may be performed in combination with the up / down movement operation. In the case where the interval between the left and right treatment elements 50, 50 can be changed, the acupuncture massage operation is combined with the interval change operation. A massage operation may be performed.

  In addition, here, a pair of left and right treatment elements 50, 50 provided as a pair of left and right treatments is shown in which only the upper treatment element 50 can be driven by the scissor drive unit 6. Only the treatment element 50 on the side can be driven by the heel drive unit 6, and further, all the treatment elements 50 can be driven by the heel drive unit 6. It may be. In this case, the acupuncture massage operation by the upper treatment element 50 and the acupuncture massage operation by the lower treatment element 50 may be the same or reversed. When matched, the muscles are pushed in the same direction by the upper and lower treatment elements 50, 50, so that the muscles can be loosened in a wide area, and when reversed, the upper and lower treatment elements 50, 50 An effective massage can be obtained by grabbing up and down.

  In addition, the massager 50 for massage treatment and the massager 50 for massage treatment may be different. FIG. 4 shows an example of this case, in which a heel drive unit 6 including a treatment element 50 dedicated to heel massage is disposed on the lower end side of the massage mechanism. It should be noted that the heel drive unit 6 including the treatment element 50 dedicated to heel massage does not have to be disposed at the position of the illustrated example, and may be disposed at any position of the massage mechanism.
