(Problem that the invention attempts to solve) The conventional pine surge machine mentioned above is
Only the outer pine surge roller moves toward the side wall of the frame against the spring to widen the distance between it and the inner pine surge roller, which reduces the pine surge pressure on the inside of the legs that are spread and the pine surge on the outside. Since the pressures are different and the pine surge effect cannot be applied to the entire leg from both sides with equal pressure, there is a problem in that a satisfactory pine surge cannot be obtained. Therefore, in the present invention, even when the legs are spread apart, the legs themselves act as guides for the massaging tool, and the massaging tool comes into contact with the massaging tool so that the pine surge balls bounce intermittently along the leg line according to the distance between the legs, and the massaging tool has uniform elasticity. To provide a pine surge device capable of imparting an attractive pine surge effect by applying pressure.

It will be attached to. That is, cylindrical boss parts are fitted on the left and right sides of a rotating shaft whose both ends are supported so as to rotate together with the rotating shaft and to be slidable in the axial direction of the rotating shaft, and on both sides of the left and right cylindrical boss parts. A plurality of elastic arms are erected in a radial manner, each slanting outward, and a pine surge ball is rotatably attached to the upper part of each elastic arm,
A motor for driving the rotary shaft is installed in one of the support parts at both ends of the rotary shaft, and the left and right support parts rotate forward and reverse the endless member stretched in the length direction of the leg base. A kneading device is mounted on a base that reciprocates by the motion of the device via support levers, and is installed in a leg base provided with a flexible top sheet.

The shape of the plurality of pine surge balls radially supported by the massaging tool is preferably oval with an elliptical longitudinal section, and the size of each pine surge ball may be the same, but it is preferable that the pine surge balls have different sizes and hardnesses. Pine surge balls may be placed alternately.

As for the means for making the left and right pair of massaging tools horizontally movable on the rotating shaft, a groove is provided in the axial direction on the surface of the rotating shaft, and an elongated key member is fitted into the groove to form a protrusion in the axial direction. , a method in which a groove is formed in the fitting hole of the cylindrical boss portion of the massaging tool to fit the above-mentioned protrusion, and the boss portion is loosely fitted to the rotating shaft, or a grooved spline shaft is used as the rotating shaft; Examples include a method in which the fitting hole of the cylindrical boss is shaped to fit the spline shaft and loosely fitted therein, but such means are not particularly limited.

In addition, a chain, a wire, a belt, or the like can be used as an endless member for reciprocating the base supporting the massaging tool within the leg platform, but a chain system is preferable in consideration of operational reliability.

(Function) When the operation switch is turned on to start the device, the rotary shaft is rotated by the motor provided on the support part of the rotary shaft, and the left and right pair of massaging tools rotate in a water wheel shape. The pine surge balls on both sides intermittently contact both sides of the user's legs via the sheet and apply pine surge on both sides of the legs, while moving in the longitudinal direction of the leg base and causing the left and right legs themselves to move. It serves as a guide for the massaging tool, and the massaging tool moves laterally according to the leg spacing to perform the pine surge effect.

(Embodiment) Below, the drawings showing the embodiment of the present invention will be explained. In Figs. It has a length that can support the leg part I in the extended state, and its surface is covered with a flexible sheet 3. In the present invention, a pair of left and right massaging tools 5, 5 each having a plurality of pine surge balls 4, 4 rotating like a waterwheel are placed inside the leg base 2 having such a flexible surface sheet 3. A top sheet 3 is provided on the left and right sides of the user's leg A as shown in FIG. The pine surge balls 4, 4 are rotated and slid into contact with each other through the legs, and move in the length direction of the leg part A to apply pine surge.

To explain more specifically, the kneading device installed in the footrest 2 has a groove formed in the axial direction on the surface of the rotary shaft 6 supported at both ends, as shown in FIGS. 3 and 4. An elongated key member 7 is fitted into the groove, and a groove to be fitted with the key member 7 is formed in the fitting hole of the cylindrical boss portions 8, 8 of the massaging tools 5, 5. The left and right cylindrical boss parts 8 are loosely fitted on the left and right sides of the rotating shaft 6, and the boss parts 8, 8 are movable in the axial direction of the rotating shaft 6 while rotating together with the rotating shaft 6. . Pine surge balls 4, 4 each having an elliptical longitudinal section are rotatably attached to the elastic arm 9 to form a massaging tool 5, 5. A stopper 10 is fixed to an intermediate position of the rotary shaft 6 to restrict the inward sliding position of the cylindrical boss portions 8, and support portions 11, 11 at both ends of the rotary shaft 6 are fixed. A motor (not shown) for driving the rotating shaft 6 is provided on one side of the rotary shaft 6, and the left and right support parts 11, 11 are connected to an endless chain 12, which is stretched in the length direction of the leg base part 2.
