PEDAL MOTION PATH ADJUSTABLE ELLIPTICAL TRAINER

摘要

A pedal motion path adjustable elliptical trainer includes a base frame, a rotating mechanism assembly, a lifting mechanism, a sliding mechanism and a control mechanism. The lifting mechanism is biasable relative to the base frame, including a rail holder, a support member and two sliding rails. The rotating mechanism assembly includes two cranks coaxially pivoted with one ends thereof to the base frame, and a support link set pivotally coupled between the other ends of the cranks and slidably coupled to the sliding rails. The control mechanism is mounted between the base frame and the rail holder to control the angle of deflection of the lifting mechanism. The sliding mechanism is pivotally coupled between the control mechanism and the rail holder. Thus, the invention allows quick adjustment of the pedal motion paths, training different muscles of the legs.

主权项

1. A pedal motion path adjustable elliptical trainer, comprising:
a base frame mounted on a support surface; a lifting mechanism comprising a rail holder, a support member and two sliding rails, said rail holder being pivotally connected to said base frame and biasable relative to said base frame, said rail holder comprising two first stop portions and two second stop portions, each said sliding rail comprising a pivot portion pivotally coupled to said support member and a sliding portion slidably coupled to said rail holder; a rotating mechanism assembly comprising two opposing cranks and a support link set, said two cranks being coaxially pivotally connected to said base frame, said support link set comprising two opposing first end portions and second end portions, each of said two first end portions of said support link set being pivotally connected to one of said two cranks, each of said two second end portions of said support link set being slidably coupled to one of said two sliding rails to perform a closed-path motion; a linkage mechanism set comprising two handlebars respectively pivotally connected to opposing left side and right side of said base frame and two links respectively pivotally connected between said handlebars and said second end portions of said support link set; a control mechanism mounted between said base frame and said rail holder and adapted to control the angle of deflection of said lifting mechanism; and a sliding mechanism pivotally coupled between said control mechanism and said rail holder for enabling said sliding portions of said sliding rails to be moved relatively to each other between said first stop portions and said second stop portions of said rail holder.
