  Further, a pair of left and right forward / backward pinion gears 371a and 371a are attached to the middle portion of the forward / backward shaft 37a, and a pair of left and right arc-shaped racks 313a 313a is provided.

  Therefore, when the rotation of the forward / backward drive unit 36a is sequentially transmitted to the forward / backward gear box 361a, the forward / backward shaft 37a, and the pair of left and right forward / backward pinion gears 371a, the pair of left / right forward / backward pinion gears 371a mesh with each other. Since the arc-shaped rack 313a is moved, the treatment element driving portion 31a swings in the front-rear direction with the lifting shaft 35a as a swing fulcrum, and the treatment elements 311a and 311a advance and retreat in the front-rear direction. Become.

  The advancing / retreating shaft 37a is provided with an advancing / retreating drive amount detecting means 372a comprising a rotary encoder for detecting the amount of driving (turning) of the advancing / retreating shaft 37a by the forward / backward drive unit 36a. The forward / backward drive amount detecting means 372a is connected to the control unit 41a.

  As described above, the chair type massage machine 1a according to the present embodiment detects the respective drive amounts of the lift drive amount detection means 352a and the advance / retreat drive amount detection means 372a by the control unit 41a. The drive unit 33a and the forward / backward drive unit 36a can be driven, so that the position of the treatment element 311a can be finely controlled, and the drive of the lift drive unit 33a and the forward / backward drive unit 36a are appropriately combined. Thus, the shoulder, back, waist, etc. of the body of the user can be massaged in various modes.

  Further, when the forward / backward drive unit 36a is driven, acupressure massage with the treatment elements 311a and 311a is possible.

  By combining these basic operations, it is possible to massage the shoulder, back, waist, etc. of the user's body in various modes, and the amount of advancement / retraction of the treatment elements 311a and 311a can be simplified. Since it can be made larger than before with a simple configuration, the massage power can be adjusted in multiple stages.

  Moreover, as shown in FIG. 6, the chair type massage machine 1a of this invention is equipped with the detection means of a user's state for detecting the state of a user's human body contact part.

  That is, a plurality of advance / retreat amount detection points P, P,... For detecting the advance / retreat amounts of the treatment elements 311a, 311a by the advance / retreat driving amount detection means 372a are provided at predetermined intervals in the elevation range of the treatment mechanism 3a.

The condition of the waist), the shoulder position, the degree of stiffness of the user, and the like are detected. The spine curve may be displayed on the display unit 43a including a liquid crystal screen of the remote controller 4a.

  Further, the reclining mechanism 2a of the backrest portion 11a may be provided with a reclining angle detection sensor (not shown) for detecting the inclination angle of the backrest portion 11a to enable automatic correction of the shoulder position. For example, a predetermined amount of deviation corresponding to the reclining angle can be corrected. That is, an experimentally obtained standard deviation can be added.

  Furthermore, the said treatment element 311a * 311a of the chair type massage machine 1a of this invention is demonstrated in detail below.

  As shown in FIG. 7, the treatment elements 311a and 311a are constituted by circular treatment element rollers in which the hardness of the human body contact part is different in each part.

  That is, for each of the treatment elements 311a, the hard part A which is the “hard” part of the contact feeling, the soft part B which is the “soft” part of the contact feeling, and the “hard” and “soft” contact feelings. It is divided into three parts so as to be an intermediate part C, which is an intermediate part of

  For example, the hard part A, the soft part B, and the intermediate part C can be composed of a plurality of members that are connected to each other and have different hardnesses. The material of the applicable member is not particularly limited, but it can be formed so that the hardness of each part of the treatment element 311a is different by using soft or hard rubber or resin, or by varying the material or density. .

  As a method of connecting a plurality of members having different hardness in the treatment element 311a, for example, a connecting portion D as shown in FIGS. 12 and 13 can be applied. As the connecting part D in FIG. 12, the hard part A, the flexible part B and the intermediate part C are formed so as to engage with each other, and the connecting part D in FIG. The connecting tool interposed between the adjacent parts of the hard part A, the soft part B and the intermediate part C is used.

  Further, as shown in FIGS. 7 and 9, a hardness switching mechanism 38a is provided so that a desired hardness portion is directed to the human body contact portion of the treatment element 311a.

  The hardness switching mechanism 38a transmits a driving force to a motor 381a that generates a rotational driving force, a speed reducer 382a that adjusts the rotation of the motor 381a, and a treatment element rotation shaft 380a that serves as a rotation axis of the treatment element 311a. The belt drive unit 383a and the like are configured.

  Further, as shown in FIG. 9, a treatment element comprising a rotary encoder for detecting the amount of rotation of the treatment element rotation shaft 380a at one end of the treatment element rotation shaft 380a and in the vicinity of the distal end of the treatment element arm 311b. A rotation amount detection means 384a is provided. The angle of the treatment element 311a with respect to the treatment element arm 311b can be detected by the treatment element rotation amount detection means 384a.

  Therefore, any one of the hard part A, the soft part B, and the intermediate part C of the treatment element 311a can be arbitrarily switched to the human body contact part by the hardness switching mechanism 38a.

  In order to be able to arbitrarily select or execute the switching of the hardness in the treatment element 311a, as shown in FIG. 19, a “hard” button 44a, a “soft” button 45a, and an “intermediate” are provided on the remote control 4a. "Button 46a is provided.

  The “hard” button 44a, the “soft” button 45a, and the “intermediate” button 46a are used for, for example, selection and setting of a massage force in a massage program before the massage is performed, and a forced massage force during the massage is performed. It can be used appropriately in switching and the like.

  What is shown in FIG. 10 is another structure which makes the hardness of the said treatment element 311a differ in each part. That is, each of the treatment elements 311a, 311a, and 311a is configured as each of the treatment elements 311a, 311a, and 311a which are small treatment element rollers in which the hard part A, the soft part B, and the intermediate part C are independently formed. Are supported on the rotating plate 311c at equal intervals around the treatment element rotating shaft 380a. In this configuration, the hardness can be switched by the hardness switching mechanism 38a and the remote controller 4a as in the case of FIGS.

  In addition, FIG. 11 has shown the case where the contact with respect to the human body contact part in each said treatment element 311a * 311a * 311a shown in FIG. 10 becomes multiple. For example, when the treatment element 311a of the hard part A and the treatment element 311a of the intermediate part C are in contact with each other as shown in the drawing, the feeling of contact between “hard” and “intermediate” is further “midst” When the treatment element 311a of the soft part B and the treatment element 311a of the intermediate part C are brought into contact with each other, “soft” and “intermediate” contact feelings, and “slightly soft” which is intermediate between them. A feeling of contact can be provided.

  Furthermore, as another configuration for making the hardness of the treatment element 311a different in each part of the human body contact portion, configurations as shown in FIGS. 14 to 16 can be considered. A feature common to these is that the same material is used on the outer periphery of the roller-type treatment element 311a that is in contact with at least the human body contact portion, but the hardness of each portion is different.

  That is, FIG. 14 shows the treatment element 311a formed from the hollow part E, the rib part F, and the notch part G, but the hard part A in which no hollow part E exists, the two hollow parts E · E and one rib. The flexible portion B is composed of a portion F and two cutout portions G and G, and the intermediate portion C is provided with three hollow portions E, E, and E and two rib portions F and F. In particular, since a plurality of hollow portions E having different sizes are formed in the treatment element 311a, the hardness of the treatment element 311a is different in each part.

  Further, FIG. 15 shows a treatment element 311a having different hardness only by the notch part G, the notch part G is not provided as the hard part A, and the four notch parts G are provided as the soft part B, As the intermediate portion C, three cutout portions G are provided at a distance from the flexible portion B. In this way, the number of notches G formed in the treatment element 311a is different in each part so that the hardness of the treatment element 311a is different in each part.

  Further, FIG. 16 shows a treatment element 311a composed of an elastic outer contact portion H and an inner core portion I harder than the outer contact portion H, which are a plurality of members connected to each other and having different hardness. The thickness ratio of the outer abutting portion H and the inner core portion I in the radial direction is about 1: 3 for the hard portion A, about 3: 1 for the soft portion B, and about 1: for the intermediate portion C. 1 is assumed.

  As described above, in the embodiment of the treatment element 311a shown in FIGS. 14 to 16, the same material is used for the outer periphery contacting the human body contact part while the treatment element 311a is different in each part in contact hardness. Therefore, the cost can be reduced by reducing the number of members and the simple structure.

  FIG. 17 shows the hard part A, the soft part B, and the intermediate part C of the treatment element 311a formed with different outer peripheral shapes. That is, a plurality of acupressure elements J · J ·· are provided as the hard portion A, and a flat surface K is provided as the soft portion B. The intermediate part C has a normal roller outer peripheral shape.

  Therefore, the acupressure elements J, J,... Shown in FIG. 17 are acupressure points on the human body contact portion, and the user feels a "harder" contact feeling than in the case of the intermediate portion C. The flat surface K pushes against the human body contact portion, and the user feels a “softer” contact feeling than the case of the intermediate portion C.

  It should be noted that a number of convex elements L·L · · may be provided on the flat surface K as appropriate. When the treatment elements 311a and 311a carry out the kneading operation, the human body contact portion can be comfortably rubbed and massaged by the convex elements L, L,.

  As described above, the chair type massage machine 1a according to the present invention includes the detection means for the user state for detecting the state of the user, but the treatment elements 311a and 311a are placed in the state of the user. Based on the detection value of the detection means, the hardness switching mechanism 38a can be switched to a position where the hardness is different.

  For example, when the treatment elements 311a and 311a are in contact with the position of the shoulder of the user detected by the detection means of the user's condition, the contact direction is downward as shown in FIG. Therefore, it is possible to control to rotate and switch the treatment elements 311a and 311a by the hardness switching mechanism 38a so that any one of the hard part A, the soft part B, and the intermediate part C desired by the user is positioned downward. .

  Further, as shown in FIG. 18, the hardness of the treatment elements 311a and 311a can be switched according to the degree of stiffness of the treatment person detected by the detection means of the treatment person state. For example, when treating a human body part having a higher degree of stiffness than the others, the hard part A is brought into contact, and in the case of a human part having a lower degree of stiffness, the soft part B is brought into contact.

  As described above, in order to scan and detect the state of the user by the means for detecting the user's state, the treatment element 311a. When moving 311a to the human body contact portion, as shown in FIG. 20, the hardness switching mechanism 38a switches so that the hard portion A always contacts. As a result, an appropriate detection value for each advance / retreat amount detection point P · P ··· can be obtained.

  As described above, the chair type massage machine of the present invention is provided with the reclining angle detection sensor (not shown) for detecting the inclination angle of the backrest portion 11a in the reclining mechanism 2a of the backrest portion 11a. Based on the detection value of the reclining angle detection sensor, the treatment element 311a may be switched to a position having a different hardness by the hardness switching mechanism 38a.

  For example, when the backrest portion 11a changes from a standing state to a lying state, the pressing force from the treatment elements 311a and 311a to the human body contact portion also changes and becomes stronger. In this case, the hard part A can be switched to the flexible part B or the intermediate part C, or the intermediate part C can be switched to the flexible part B so that the hardness of the treatment elements 311a and 311a becomes weak.

  Conversely, when the backrest portion 11a changes from the lying state to the upright state, the pressing force from the treatment elements 311a and 311a becomes weak, so that the soft portion B is changed to the hard portion A or the intermediate portion C. Alternatively, the intermediate portion C can be switched to the hard portion A.

  So far, the present invention has been described in detail as described above. In the chair type massage machine 1a, the treatment element 311a is composed of circular treatment element rollers having different hardnesses of the human body abutting parts at respective parts. Therefore, the feeling of contact received by the user differs depending on the contact portion of the treatment element 311a with the human body contact portion at the neck and back of the seated user, or at the waist and buttocks, etc. In addition to being able to enjoy a feeling of massage, it is a relatively simple configuration that only varies the hardness in each part of the circular treatment roller, so it has excellent durability for continuous use and cost for manufacturing and maintenance It becomes.

  The treatment element 311a is switched to a position having a different hardness by the detection means for detecting the state of the human body abutting portion. It is possible to always carry out a suitable massage while avoiding the feeling of contact being too strong and causing pain.

  Furthermore, since the treatment element 311a is composed of a plurality of members that are connected to each other and have different hardnesses, a wide variety of combinations of members having different hardnesses are possible, and massage according to the intended use of the user is performed. It can be done.
