  The massage chair of the present invention is circular in the vertical and / or horizontal plane by the vertical and horizontal drive eccentric columns connected to the rotation shafts of the vertical drive motor and the horizontal drive motor while the tray of the interlocking base mechanism is kept substantially horizontal. Since an undulating pulsation and a rotational pulsation that draw a motion are generated, a large massage effect on the buttocks can be obtained when the user sits on the tray.

  The preferred embodiments of the present invention will be specifically described below with reference to the drawings. However, the present invention is not limited to these.

  The massage chair according to the present invention comprises an interlocking base structure having a tray as one of the constituent elements, a vertical driving means for driving the tray in the vertical direction, and a horizontal driving means for driving in the horizontal direction. .

  As a specific example, FIG. 1 shows an exploded view (perspective view) of the entire massage chair, and FIG. 2 shows a three-dimensional view (perspective view) of the interlocking base structure.

  The interlocking base structure includes a bottom plate, a tray that is opposed to the bottom plate and on which a user sits, and an elastic element that supports the tray substantially horizontally above the bottom plate.

  The material of the bottom plate and the tray is not particularly limited, and the same material or different materials may be used. From the viewpoint of durability and workability, wood, hard resin, metal material, etc. are used. Also, the dimensions and shape need not be the same. The names of the bottom plate and the tray mainly assume a plate material, but do not exclude shapes such as a frame shape, a block shape, and a column shape. In this case, the normal direction is the direction perpendicular to the surface on which the user is seated.

  The bottom plate may be directly grounded to the ground or a base, or may be held at a predetermined mounting angle on a chair base described later. On the other hand, since the user sits on the tray, it is necessary to maintain a substantially horizontal position not only when the user is standing still but also when the tray is rotated by the vertical drive means or the horizontal drive means.

  The elastic element elastically places the bottom plate and the tray together. The type and shape of the elastic element, and the joining method and location of the bottom plate and tray and the elastic element are not particularly limited. From the viewpoint of assembly and maintenance efficiency, the elastic element is a spring material, and the joining method is the bottom plate and tray. The fitting system with respect to the fitting protrusion provided in the surface of is illustrated. However, it is necessary to prevent the spring material from being detached from the fitting protrusion particularly when driven longitudinally.

  In FIG. 1, 10 is an interlocking base structure, 11 is a bottom plate, 12 and 15 are fitting projections, 13 is a spring material as an elastic element, and 14 is a tray. The tray 14 can be held substantially horizontally by appropriately adjusting the length of the spring material 13 and the spring rigidity according to the mounting angle of the bottom plate 11.

  The vertical drive means has a function of circularly moving the tray 14 in a vertical plane in a state where the tray 14 is kept substantially horizontal and the rotation around the normal line of the tray 14 is excluded. Similarly, the lateral drive means has a function of circularly moving the tray 14 in a horizontal plane in a state in which the tray 14 is kept substantially horizontal and the rotation around the normal line of the tray 14 is excluded. It is desirable that both of them have such a function both when operating simultaneously and when operating independently.

  The longitudinal / lateral driving means can be realized by appropriately combining pistons, rack and pinions, eccentric cams, motors, magnetic forces, and the like, and is not particularly limited as long as it has the above functions.

  FIG. 3 illustrates vertical drive means and horizontal drive means. Reference numeral 16 denotes a longitudinal braking element connected to the tray and extending downward, 20 is a longitudinal driving motor, and 30 is a lateral driving motor.

  The vertical drive motor 20 is fixed substantially horizontally on the upper surface of the bottom plate 11 via a bracket or the like. A longitudinal drive eccentric column 22 is connected to the longitudinal drive motor 20 with an offset from the rotation shaft 21, and revolves around the rotation shaft 21 as the rotation shaft 21 rotates. The rotating shaft 21 and the longitudinal drive eccentric column 22 may be fixed, or may be freely rotatable around the eccentric column 22 or may be connected appropriately via a plate material or the like. One end of the vertical braking element 16 is fixed to the lower surface of the tray 14 and a slot 161 is provided at the other end. A longitudinal drive eccentric column 22 is fitted in the slot 161, and the eccentric column 22 is freely pivoted about its axis.

  The lateral drive motor 30 is fixed substantially vertically on the upper surface of the bottom plate 11 via a bracket or the like. A lateral drive eccentric column 32 is connected to the lateral drive motor 30 with an offset from the rotational shaft 31, and revolves around the rotational shaft 31 as the rotational shaft 31 rotates. The rotating shaft 31 and the longitudinal drive eccentric column 32 may be fixed, or may be freely rotatable around the eccentric column 32, or may be connected appropriately via a plate material or the like. The horizontal braking element 17 fixed to the tray 14 or the lower surface of the tray 14 is provided with a slot 171. A lateral drive eccentric column 32 is fitted in the slot 171, and the eccentric column 32 rotates freely about its axis and is axially attached.

  The materials of the longitudinal drive eccentric column 22, the lateral drive eccentric column 32, the longitudinal direction braking element 16, and the lateral direction braking element 17 are not particularly limited, and may be the same or different from each other. It can be selected as appropriate.

  The pulsation operation of the tray 14 obtained by combining the interlocking base structure and the vertical / horizontal driving means will be described with reference to FIG. Note that a sheet 50 (to be described later) is attached to the tray 14. When the vertical drive motor 20 rotates the rotary shaft 21, the vertical drive eccentric column 22 connected in an offset manner revolves around the rotary shaft 21. Such rotation is transmitted to the longitudinal braking element 16 through the slot 161, and the braking element 16 and the tray 14 fixed thereto are pulsated and circularly moved in the vertical plane. However, since the slot 161 and the longitudinal drive eccentric column 22 are freely rotatable and pivotally mounted, the tray 14 is circularly moved in the vertical plane while maintaining substantially horizontal as indicated by arrows on both sides of the sheet 50 in the drawing, that is, Revolves and rotates. Further, since no other translation / rotation component in the out-of-plane direction with respect to the vertical plane is generated, the tray 14 does not rotate around the normal line. Therefore, the vertical direction (pitch angle) of the user sitting on the seat 50 is maintained.

  Further, the lateral drive motor 30 (not shown in FIG. 4) is fixed to the bottom plate 11 substantially vertically via a bracket as shown in FIG. 3, and the lateral drive eccentric column 32 and the horizontal brake are rotated along with the rotation of the rotary shaft 31. The element 17 and the tray 14 are pulsated and moved circularly in the horizontal plane as indicated by an arrow shown at the center of the sheet 50 in the drawing. Also in this case, since the slot 171 and the lateral drive eccentric column 32 are freely rotatable and pivotally mounted, the tray 14 does not rotate around its normal line even when the motor is driven, and only revolves. Therefore, the right and left direction (yaw angle) of the user sitting on the seat 50 is maintained.

  As described above, the massage chair according to the present invention can rotate the tray and the seat greatly while maintaining the posture of the user sitting on the massage chair. Compared to the conventional technology that gives vibration, it can give a large massage effect to the buttocks.

  It should be noted that the lengths of the slots 161 and 171 and the lengths of the longitudinal / lateral drive eccentric columns 22 and 32 are sufficient so that the eccentric columns do not fall out of each other slot by the operation of the longitudinal / lateral drive motors. It is preferable to provide an anti-detachment mechanism (not shown) in the shaft attachment portion.

  Further, the radius of the circular motion of the tray 14 can be changed by increasing or decreasing the offset lengths of the motor rotating shaft 21 or 31 and the vertical / horizontal drive eccentric column 22 or 32, respectively. That is, by providing the motor 20 or 30 with an offset length adjusting mechanism (not shown), it is possible to change the revolving rotation stroke of the tray 14 and adjust the massage strength.

  Furthermore, the direction in which the tray 14 pulsates can be changed by changing the fixing direction of the vertical drive motor 20 with respect to the bottom plate 11 at an angle of 0 to 180 degrees. Accordingly, the direction of the interlocking base structure 10 is not changed, and a motor mounting angle adjusting mechanism (not shown) that continuously or intermittently changes the mounting angles of the bottom plate 11 and the tray 14 and the vertical driving motor 20 and the vertical braking element 16 is provided. Thus, the trajectory of the revolution rotation of the tray 14 can be changed, and stimulation from different directions can be given to the user's buttocks, which is preferable.

  Hereinafter, the massage chair according to the present invention will be described in detail with reference to the drawings with respect to an embodiment provided with additional components. However, the present invention is not limited to these examples.
