Rowing and swimming exerciser

DETAILED DESCRIPTION The primary objective of the present invention is to provide an exerciser including a seat and a handle that may be rotated about an erected axis respectively and that are coupled together by gears for allowing the handle to be rotated by the seat when the seat is rotated about the vertical axis.
In addition, the handle itself may be rotated about a lateral axis for allowing the exerciser to be executed as a rowing and swinging exerciser.
In accordance with one aspect of the invention, there is provided an exerciser comprising a base, a shaft and an axle rotatably secured on the base, a seat secured to the shaft and rotatable relative to the base about the shaft, means for coupling the shaft to the axle and to rotate the axle with the seat when the seat is rotated about the shaft, and a handle rotatably secured to the axle at a pivot pole for allowing the handle to rotate relative to the base about the axle and for allowing the handle to rotate relative to the axle about the pivot pole.
The coupling means includes a first gear secured on the shaft and rotated in concert with the shaft, and a second gear secured on the axle and rotated in concert with the axle and engaged with the first gear for allowing the axle to be rotated by the shaft and for allowing the shaft to be rotated by the axle.
A resistive means is further provided for applying a resistive force against a rotational movement of the seat relative to the base about the shaft.
A foot support is further rotatably secured to the base at a pivot spindle, and the exerciser further comprises a means for coupling the shaft to the foot support and to rotate the foot support about the pivot spindle when the shaft is rotated.
The first gear includes a bar secured thereon and rotated in concert with the first gear, and at least one link pivotally coupling the bar to the foot support for coupling the shaft to the foot support.
A rod is rotatably secured to the base and coupled to the axle for allowing the rod to be rotated by the axle when the axle is rotated
