Abstract: A foot massage device includes a motor connected to an underside of a top plate and hanged in a hole in a base. A plurality of flexible members are connected between the base and the top plate. A weight member is eccentrically connected to the output shaft of the motor so that when the output shaft rotates, the weight member rotates eccentrically to move the motor and the top plate. Due to the flexibility of the flexible members, the top plates reciprocally moves and a pad with stimulation protrusions is connected on a top of the top plate to provide massage function to the feet put on the pad.

Abstract: A swing machine includes a casing having a sliding member movably engaged with a rail and the sliding member is driven by a block eccentrically connected to an output shaft of a motor. A support member is connected to a top of the sliding member. A first protrusion extends from a side of the sliding member and a limitation member located in the casing has a wave-shaped slot in which the second protrusion is movably engaged.

Abstract: A waist exerciser includes a casing supported on two support posts and two blocks are rotatably connected to two ends of a shaft in the casing. A locking member is movably received in each of the blocks and has a plurality of first holes. Each of the blocks has a plurality of second holes which are located in alignment with the first holes. A belt has two ends which of which has a pin for inserting in the aligned first hole and second hole. Each of the pins has a groove and a periphery of the first hole is movably engaged with the groove so as to prevent the pin from disengaging from the holes.
