Description

  The present invention relates to a massage machine implemented as, for example, a chair-type massage machine or the like, which includes a treatment element that performs a kneading operation, a tapping action, or a combined action of tapping and tapping.

  Conventionally, as shown in FIG. 5, for example, a chair-type massage machine has a seat portion 31 and a backrest portion 32 that can adjust an inclination angle at a rear portion thereof, and includes armrests 33 on both left and right sides of the seat portion 31. The backrest portion 32 is formed by providing a head rest 35 at the upper end of a vertically long rectangular frame 34, attaching a cushion material appropriately to the outer periphery of the frame 34, and covering the whole with a cover 36. In the frame 34, a kneading ball drive unit 37 is arranged so as to be movable up and down.

  As shown in FIG. 6, two cylindrical members 40 are arranged on the rotation axis 38 for the kneading ball drive unit 37 from the center of the left and right sides of the chassis 39 with respect to the axis of the rotation shaft 38 for the kneading. The lever 43 made of a stainless steel plate is supported on each cylinder member 40 via a bearing 41 and a bearing holder 42 so as to freely rotate.

  The stainless steel plate lever 43 has a pair of levers 43 for rotation between a support portion (fixed portion with the bearing holder 42) to the fir rotating shaft 38 and a free end to which an arm 44 described later is attached. It is bent 43a so that the distance at the free end is wider than the distance at the support portion to the shaft. On the free end of the lever 43, a substantially intermediate portion of the arm 44 having the balls 45 attached to both ends thereof is supported so as to be rotatable within a certain range.

  The left and right fir balls 45 can be selected from three types of massage operations: fir operation, tapping operation or combined operation of fir and tapping, by means of a kneading motor 46 and a tapping motor 47 (Patent Literature). 1).

  Therefore, according to the chair type massage machine configured as described above, a large force is applied to the lever 43 from the kneading balls 45 via the arm 44 by the massage operation of the kneading and tapping, but the lever 43 is thin. However, since it is formed from a stainless steel plate having high rigidity, sufficient strength can be obtained. On the other hand, even if an excessive load is applied between the left and right fir balls 45, 45 due to the bent portion 43a formed on the lever 43, the levers 43, 43 are easily bent in the direction in which the interval is widened. An elastic effect can be obtained. Accordingly, the kneading balls 45 have an effect of giving a soft contact feeling to the treatment site.

  Further, in the same massage machine as described above, the pair of arms 51 are plate-like and have elasticity in directions facing each other as shown in FIGS. It is assumed that a roller-shaped treatment element 52 is attached, and a portion opposite to the treatment element 52 is detachably connected to the link member 54 via a spherical joint 53. The elasticity of the arms 51, 51 allows the treatment element 52 to escape when an object is sandwiched between the two treatment elements 52, 52 and prevents an excessive force from being applied to the object.

  Further, the arm 51 has a movable portion 56 formed on the radial bearing housing member 55 side, and can be exchanged for the radial bearing housing member 55. Thereby, the arm 51 can be changed to one having a different elastic deformation rate (spring constant) (Patent Document 2).

Therefore, according to the massage machine configured as described above, since the arm 51 is formed of an elastic plate having elasticity, safety as a massage machine can be improved, and at least the treatment element 52 in the arm 51 is provided. By making this part detachable with respect to other parts, the elastic coefficient of the arm 51 can be selected.

  By the way, in the conventional massage machine shown in FIGS. 5 and 6 and FIGS. 7 and 8, the lever 43 and the arm 51 have elasticity in the left-right direction. It is possible to provide a soft touch sensation and to improve the safety as a massage machine.

  However, in the conventional massage machine, the lever 43 and the arm 51 have elasticity in the left and right direction, but not in the vertical direction. (For example, the position of the shoulder) and the position of the kneading ball 45 or the treatment element 52 are not matched, even if an excessive load is applied to the shoulder of the user by the kneading ball 45 or the treatment element 52 (striking operation) However, there is a problem that the user cannot obtain an appropriate massage effect and may hurt the treatment site. .

  Therefore, the present invention has an object to solve the above-mentioned conventional problems, and the treatment element support such as a lever or an arm is elastic in all directions, not only in the left-right direction but also in the up-down, front-back, and diagonal directions. In addition, it is possible to give a soft contact feeling to the treatment site in the scrubbing operation, the hitting operation or the combing operation of the scissors and the hitting by the treatment element, and the safety as a massage machine can be improved. The purpose of the present invention was to provide a massage machine that can select an elastic coefficient and that can be obtained by an appropriate massage effect by changing the user to one having an arbitrary elastic coefficient. Is.

  Therefore, in the massage machine of the present invention, the massaging rotary shaft 10 of the massaging element drive unit 7 is attached to the massaging element support 20 made of a coil spring, and the massaging element 21 is further attached to the free end of the massaging element support 20. It is supposed to be.

  And the massage machine of this invention shall arrange | position the said treatment element drive unit 7 to the flame | frame 4 of the backrest part 2 of a chair type massage machine so that raising / lowering is possible.

  Further, in the massage machine of the present invention, the treatment element support 20 is detachably attached to the rotary shaft 10 for fir.

  In the massage machine of the present invention, the treatment element 21 attached to the treatment element support body 20 is mixed with the kneading operation motor, the tapping operation motor 17 and the tapping operation motor 17 with the kneading operation, the tapping operation, or the combined use of the kneading and tapping. Three types of massage operations can be selected.

  Since the massage machine of the present invention is configured as described above, it is possible to give a soft contact feeling to the treatment site in the scrubbing operation, the striking operation or the combing operation of the scissors and the tapping with the treatment element, Safety as a massage machine can be increased, and the elastic coefficient of the treatment element support can be selected. By changing the user to one having an arbitrary elastic coefficient, an appropriate massage effect can be obtained. It became something that can be obtained.

  Hereinafter, the best mode for carrying out the massage machine of the present invention will be described in detail with reference to the drawings.

  The figure shows the form which implemented the massage machine of this invention to the chair type massage machine, FIG. 1 has shown the whole sectional view of the massage machine, FIG. 2 is explanatory drawing of the treatment element drive unit of the massage machine Is shown.

  In the figure, the massage machine of the present invention has a seat portion 1 and a backrest portion 2 at the rear portion thereof so that the inclination angle can be adjusted, and armrests 3 are provided on both the left and right sides of the seat portion 1. The backrest part 2 is formed by providing a head rest 5 at the upper end of a vertically long rectangular frame 4, attaching a cushion material appropriately to the outer periphery of the frame 4, and covering the whole with a cover 6. A treatment element drive unit 7 is disposed in the frame 4 so as to be movable up and down.

  Rollers 9 are provided at both left and right ends of the chassis 8 of the treatment element drive unit 7, and these rollers 9 are fitted to guide rails (not shown) which are left and right frames of the frame 4 so as to be rollable. The treatment element drive unit 7 moves the guide rail up and down.

  The treatment element drive unit 7 is supported by an upper part of the rear side of the chassis 8 with a rotary shaft 10 for scissors and a lower part of a rotary shaft for hitting (not shown) rotatably in the lateral direction. The rotary shaft 10 is connected to a motor 14 via a pulley 12 and a belt 13 of the worm gear device 11, and the rotary shaft for hitting is connected to a motor 17 via a pulley 15 and a belt 16.

  Two cylindrical members 18 are fitted and fixed to the rotary shaft for kneading at a position where the chassis 8 is distributed substantially from the left and right center with respect to the axis of the rotary shaft for kneading 10. The treatment element support body 20 is attached via this. In this case, it is preferable that the treatment element support 20 is attached to each cylindrical member 18 so as to be detachable.

  The pair of treatment element supports 20 are inclined outward so that the distance at the free end is wider than the distance at the support portion to the fir rotating shaft 10. The treatment element support 20 is made of a coil spring, and has elasticity in all directions of up and down, front and rear, and diagonal as well as the left and right direction. Further, a treatment element 21 for tapping is rotatably attached to the free end of the treatment element support 20 through an extension 20a. As the coil spring, a compression spring is usually used, but a tension spring, a torsion spring, or the like can be used, and a cylindrical coil spring is usually used, but a conical coil spring or the like can also be used.

  Therefore, when the kneading rotary shaft 10 is rotated by the motor 14, the treatment element support 20 disposed symmetrically and obliquely to the kneading rotary shaft 10 moves so as to expand and contract between the tips thereof, thereby treating the treatment. The child 21 performs the scuffing operation. Further, when the tapping rotary shaft is rotated by the motor 17, an eccentric rotating member (not shown) rotates eccentrically to move the rods 22 and 22 up and down, and this vertical movement is transmitted to the treatment element support body 20, thereby treating the treatment element. The treatment element 21 attached to the support 20 is moved up and down. This vertical movement of the treatment element 21 is a tapping action.

  That is, the treatment element 21 can be selected from three kinds of massage operations, ie, a scissor operation, a striking operation, or a combined operation of scissors and striking, by a scissor motor 14 and a striking motor 17. Although the treatment element 21 is made of a rubber elastic body or the like, it may be made of a material that can give an appropriate massage effect to the user by a scuffing operation or a tapping operation.

  Therefore, according to the massage machine of the present invention configured as described above, the position of the user's treatment site (for example, the position of the shoulder) and the position of the treatment element 21 are not matched due to the massage operation of fir and tapping. In this case, even if a large force is applied to the treatment element support 20 through the treatment element 21, the treatment element support 20 has elasticity in all directions, so that a soft contact feeling can be given to the treatment site. Thus, the user does not hurt the treatment site, and safety as a massage machine can be improved.

  Further, according to the massage machine of the present invention, when the treatment element support 20 is detachably attached to the kneading rotary shaft 10, the treatment element support 20 having an arbitrary elastic coefficient selected by the user is provided. By changing, an appropriate massage effect according to the user can be obtained.

  Moreover, the massage machine of this invention shall incorporate the pneumatic massage mechanism (not shown) in the appropriate position of the seat part 1 or the backrest 2, and can perform the massage operation by expansion | swelling and shrinkage | contraction of an air bag to the said treatment drive unit 7 It can be used in combination with the scrubbing and tapping operation of the treatment element 21. The massage operation by the expansion and contraction of the air bag has an effect of giving a soft feeling to the user by an appropriate surface stimulation. Therefore, if it is used in combination with the kneading and tapping operation of the treatment element 21, it is more excellent. A massage effect can be obtained.

  Furthermore, the massage machine according to the present invention is a chair type massage machine in which a footrest (not shown) is attached to the front lower portion of the seat portion 1, and the treatment element drive unit 7 having the same mechanism as described above is attached to the footrest. It can also be equipped. In this case, the pneumatic massage mechanism can be used in combination with the footrest.

  In the massage machine of the present invention, the treatment element 21 may be provided with an internal or external vibration mechanism (not shown). As a result, the massage machine of the present invention can be equipped with a vibration function, and when used in combination with the kneading and tapping operation of the treatment element 21, further massage effects such as kneading vibration, tapping vibration, or tapping vibration are provided. It can be expected.
