It is possible to slide outward in the direction.
(Example 3)
FIG. 12 is a schematic diagram showing a tilting mechanism 53 that can tilt the right footrest 4a and the left footrest 4b as still another configuration of the moving mechanism 50, and when the tilting mechanism 53 and the footrest 4 are viewed from the back. Is shown. Note that the tilt mechanism 53 shown in FIG. 12 has the same configuration as the tilt mechanism 52 according to the second embodiment. Therefore, here, a description will be given focusing on a configuration different from the tilting mechanism 52 according to the second embodiment.

  As shown in FIG. 12, the tilting mechanism 53 has a support frame 17 disposed behind the right footrest 4a and the left footrest 4b. The support frame 17 includes an upper frame 17a, left and right vertical frames 17b, and a lower frame 17c as in the tilting mechanism 52 according to the second embodiment. Further, in the third embodiment, the support frame 17 is provided between the left and right vertical frames 17b. A central frame 17d is provided. The center frame 17d has an upper portion connected to the upper frame 17a, a lower portion connected to the lower frame 17c, and is arranged in parallel with the left and right vertical frames 17b.

  Further, the tilt mechanism 53 of the third embodiment includes four air bags 91 to 94. Of these, the two air bags 91 and 92 are vertically arranged between the left side surface of the right footrest 4a and the right side surface of the central frame 17d, and the remaining two air bags 93 and 94 are provided on the left footrest 4b. It is arranged up and down between the right side surface and the left side surface of the central frame 17d. That is, in FIG. 12, an air bag 91 is arranged at the upper right, an air bag 92 is arranged at the lower right, an air bag 93 is arranged at the upper left side opposite to the air bag 92, and an air bag 94 is arranged at the lower left. Yes. These air bags 91 to 94 can be expanded and contracted by air supply / exhaust from the air supply / exhaust device 9 by connecting to the air supply / exhaust device 9 (see FIG. 9) via an air hose. .

  In addition, coil springs 95 and 95 are provided above and below the right footrest 4a and the center frame 17d so as to correspond to the air bags 91 to 94, and above and below between the left footrest 4b and the center frame 17d. Are provided with coil springs 96. The former coil spring 95 urges the right footrest 4a in a direction (left direction) close to the center frame 17d, and the latter coil spring 96 urges the left footrest 4b in a direction (right direction) close to the center frame 17d. is doing.

  Further, the tilting mechanism 53 is provided with arc guide rails 80 similar to those described in the second embodiment with respect to the left and right vertical frames 17b, and the right and left footrests 4a and 4b are provided with the guide rails. A guide roller 84 that rolls along 80 is attached.

  The tilting mechanism 53 having such a configuration can tilt the right footrest 4a and the left footrest 4b in the left-right direction by supplying and exhausting air to the air bags 91-94. FIG. 13 is a view for explaining a situation where both the right footrest 4a and the left footrest 4b are tilted to one side.

  First, as shown in FIG. 12, when none of the air bags 91 to 94 is supplied with air, the right footrest 4a and the left footrest 4b come close to each other by the biasing force of the coil springs 95 and 96, and are in an upright state ( The state is not tilted. Next, as shown in FIG. 13, when air is supplied only to the lower right air bag 92 and the upper left air bag 93, these air bags 92, 93 resist the urging force of the corresponding coil springs 95, 96. Expands. Then, the right footrest 4a tilts so that its lower part is separated from the central frame 17d to the right, and the left footrest 4b tilts so that its upper part is separated from the central frame 17d to the left. Therefore, as a whole, the right footrest 4a and the left footrest 4b are inclined in the counterclockwise direction so that the lower portion is positioned on the left side with respect to the upper portion, that is, in the rear view shown in FIG. Further, when the air supply to the air bags 92 and 93 is stopped from the state shown in FIG. 13 and natural exhaust is performed, the air bags 92 and 93 are contracted by the biasing force of the coil springs 95 and 96, respectively, as shown in FIG. It will return to the state.

  In addition, when only the upper right air bag 91 and the lower left air bag 94 are supplied with air, the lower part of the right footrest 4a and the left footrest 4b are positioned on the right side of the upper part. That is, it tilts clockwise in the rear view. Even in this case, if air supply to the air bags 91 and 94 is stopped and natural exhaust is performed, the air bags 91 and 94 are contracted by the urging forces of the coil springs 95 and 96, respectively, to the state shown in FIG. Will return.

  When the footrest 4 is operated as described above by the tilting mechanism 53 in a state where the user is seated on the seat of the chair type massage machine 1, the treatment to the user as shown in FIG. It can be carried out. That is, when the tilting mechanism 53 is driven as shown in FIG. 13 and both the right footrest 4a and the left footrest 4b are tilted to one side, as shown in FIG. 14 (e), the right lower leg and left lower leg of the user are shown. Can be tilted to one side and stretch the pelvis or twist the waist.

  Note that the tilting mechanism 53 according to the third embodiment also expands and contracts the air bags 91 to 94 at the same timing, so that the right footrest 4a and the left footrest 4b are moved in the horizontal direction as shown in the first embodiment. It is possible to slide outward. Furthermore, when only the right side air bladders 91 and 92 or only the left side air bladders 93 and 94 are inflated and contracted at the same timing, only the right footrest 4a or the left footrest 4b is slid to the left and right outwards. Is also possible. In this case, it is possible to perform stretching by moving only the right leg or the left leg of the user so as to open left and right.

  Moreover, the chair type massage machine 1 which concerns on this Embodiment is provided with the air bags 2e and 2e, as shown in FIG. 2, and tilts the cushion part 2c of the seat part 2 to right and left by expanding and contracting these. Be able to. Therefore, it is possible to tilt the right footrest 4a and the left footrest 4b to one side by the tilting mechanism 53, and to tilt the cushion portion 2c of the seat portion 2 to one side. Specifically, as shown in FIG. 13, the right footrest 4a and the left footrest 4b are tilted counterclockwise in the rear view, and the air bag 2e is inflated so that the cushion portion 2c is counterclockwise in the rear view. Can be tilted to. Thereby, the improvement of the stretch effect to a user's pelvis and a waist | hip | lumbar part can be anticipated.

  In addition, by operating the back twisted portion 3a provided on the backrest portion 3 of the chair type massage machine 1, it is possible to perform general stretching of the user. That is, for example, by the tilt mechanism 53 shown in FIG. 12, the right footrest 4a and the left footrest 4b are tilted counterclockwise in the rear view, and the air bag 2e is inflated to cause the cushion portion 2c to rotate counterclockwise in the rear view. Tilt in the direction and twist the lower body of the user counterclockwise in the rear view. At the same time, the left air bag 3b of the back twisted portion 3a is inflated so that the upper half of the user is twisted so that the left half is positioned forward (facing the right side). By doing so, as shown in FIG. 14 (f), since the upper and lower body of the user are twisted in opposite directions, systemic torsion massage, especially torso massage in particular, is effective. Can be done automatically.

  In the chair type massage machine 1 according to the present embodiment, for example, the right footrest 4a and the left footrest 4b are tilted counterclockwise in the rear view, and the air bag 2e is inflated to cushion the cushion portion 2c. Can be tilted clockwise as viewed from the rear, and the air bag 3b on the right side of the back twisted portion 3a can be inflated. In this case, the lower leg of the user is tilted to the left, the buttocks are lowered to the right, and the upper body is twisted so as to face to the left, so that a whole-body torsion massage can be performed.

  Furthermore, the chair type massage machine 1 according to the present embodiment includes lower leg support portions 10A and 10B and foot support portions 11A and 11B. Accordingly, it is possible to perform stretching to the user as shown in FIGS. 14B to 14F in a state where the lower leg, the instep, the heel and the like are gripped. In this case, since each stretch is performed while holding one or more of the lower leg, the instep, and the heel of the user, the treatment is performed for the operations of the right footrest 4a and the left footrest 4b. The lower leg of the person can be appropriately followed, and further improvement of the stretch effect can be expected.

  In the above description, it is described that the lower leg support portions 10A and 10B and the foot support portions 11A and 11B “grip” the lower leg, the instep, the heel and the like by the inflation of the air bags 34, 35, and 44 to 48. However, “gripping” in this case does not mean only a state in which the corresponding body part is gripped to the air bags 34, 35, 44 to 48 so as to be completely fixed. In addition, it includes a state in which a slight relative displacement occurs. Eventually, “grabbing” a body part refers to a state where the body part is in contact with the body part in a manner that can limit displacement to some extent.

  By the way, in the above description, the right footrest 4a and the left footrest 4b inflate one or more of the air bags 34, 35, 44 to 48, thereby grasping the user's lower leg, instep, heel, etc. However, the present invention is not limited to this, and for example, it is possible to support the lower leg without using an air bag.

  FIG. 15 is a perspective view showing a footrest 104 having another configuration, and shows a chair type massage machine 1 shown in FIG. 1 according to the present embodiment that can be applied in place of the footrest 4. The footrest 104 includes a right footrest 104a having a right leg support wall 110a and a right foot support wall 111a that are integrally formed, and a left footrest 104b having a left leg support wall 110b and a left foot support wall 111b that are integrally formed. It has.

  The right lower leg support wall 110a includes a side wall 130 that supports the right lower leg of the user from the left and right outer sides, a rear wall 131 that supports from the back side, and an inner wall 132 that supports the left and right inner sides. A concave groove having an open end is formed. The right foot support wall 111a includes an outer wall 140 that supports the user's foot from the left and right outer sides, a rear wall 141 that mainly supports the heel from the back side, an inner wall 142 that supports the left and right inner sides, and a sole. It has a bottom wall 143 to be supported, and is configured in a concave shape in which the front and upper sides are open. The outer wall 130 and the inner wall 132 of the right leg support wall 110a and the outer wall 140 and the inner wall 142 of the right foot support wall 111a have substantially the same length in the front-rear direction, and the dimension in the front-rear direction of the bottom wall 143. It is almost the same. Further, the outer wall 140, the rear wall 141, and the inner wall 142 included in the right foot support wall 111a are connected to the lower portions of the outer wall 130, the rear wall 131, and the inner wall 132 included in the right leg support wall 110a so as to be substantially flush with each other. The right leg support wall 110a and the right foot support wall 111a are integrally configured.

  Therefore, when the right footrest 104a including the right lower leg support wall 110a and the right foot support wall 111a configured as a whole is viewed as a whole, the upper surface and the front surface are removed from the vertically long rectangular parallelepiped. The separation distance between the outer walls 130 and 140 and the inner walls 132 and 142 is preferably substantially the same as or slightly larger than the lateral dimensions of the lower leg and foot of the user. Further, since the left footrest 104b is symmetrical with the right footrest 104a, a detailed description thereof is omitted here.

  In the case of the footrest 104 having such a configuration, the outer walls 130 and 140 and the inner walls 132 and 142 extend relatively large forward, and the lower leg and foot of the user when the foot is placed on the bottom wall 143, It can be supported from the left and right and from the rear. For such a footrest 104, air bags may be provided on the outer walls 130, 140, the rear walls 131, 141, the inner walls 132, 142, and the like. Needless to say, it is possible to more reliably support the lower leg and the foot of the user by inflating the air bag.

  The present invention has been unprecedented such as stretching the pelvis of the user by making the footrest movable in the left-right direction, for example, allowing it to slide in the left-right direction or tilting in the left-right direction. The present invention can be applied to a chair type massage machine that enables the treatment of the aspect.
