Abstract
A combined cycling and stepping exerciser includes a base frame with an upright post, a drive wheel mounted on the base frame, a pair of elongated lever arms with front end portions pivoted to the upright post, a pair of slide seats, and pair of pedal arms disposed on the lever arms. Each of the lever arms has a longitudinal slide groove. Each of the slide seats is coupled to a respective crank arm of the drive wheel, and engages slidably the slide groove in a respective lever arm so as to be slidable along the slide groove. Each of the pedal members has a front end engaging slidably the slide groove in a respective lever arm. A pair of fasteners are operable for fastening rear ends of the pedal members selectively and respectively to the slide seats and to rear end portions of the lever arms.
Claims21
A combined cycling and stepping exerciser comprising:
- a base frame having a front end portion with an upright post, and a rear end portion opposite to said front end portion in a longitudinal direction, said upright post being formed with a pair of horizontal pivot shafts that project in opposite lateral direction transverse to the longitudinal direction;
- a drive wheel mounted rotatably on said rear end portion of said base frame, said drive wheel having a horizontal wheel axle transverse to said longitudinal direction, and a pair of crank arms coupled to said wheel axle and disposed on opposite lateral sides of said drive wheel;
- a pair of elongated lever arms disposed on opposite lateral sides of said base frame, each of said lever arms having a front end portion pivoted to a respective one of said pivot shafts on said upright post, a rear end portion, and a longitudinally extending slide groove extending between said front and rear end portions;
- a pair of slide seats, each of which is coupled to a respective one of said crank arms and engages slidably said slide groove in a respective one of said lever arms so as to be slidable along said slide groove when said drive wheel rotates;
- a pair of pedal members disposed respectively on said lever arms, each of said pedal members having a front end engaging slidably said slide groove in the respective one of said lever arms, and a rear end;
- and
- fasteners which are operable for fastening said rear ends of said pedal members selectively and respectively to said slide seats and to said rear end portions of said lever arms.
A combined elliptical cycling and stepping exerciser, comprising:
- a frame configured to be supported on a horizontal surface;
- and
- a dual crank arm mechanism including left and right pedal members,
- each of said left and right pedal members having a foot engaging portion configured to support a foot of a user and opposite end portions,
- said dual crank arm mechanism being constructed and arranged with respect to the pedal members so that the pedal members can be selectively moved in either an elliptical cycling mode or a stepping mode,
- each of said pedal members, when in the elliptical cycling mode, being operatively associated with said dual crank arm mechanism so that one end portion thereof moves along a preselected path while the opposite end portion thereof moves in a circular orbital path about a fixed transverse rotational axis provided on said frame, so that when the exerciser is in use in said elliptical cycling mode, and when a foot of the user which is disposed upon the foot engaging portion thereof travels forwardly from a rearwardmost position, the heel portion of the user's foot associated therewith initially rises at a faster rate than the toe portion, and when the foot travels rearwardly from a forwardmost position, the heel portion of the user's foot initially lowers at a faster rate than the toe portion,
- each of said pedal members, when in the stepping mode, being operatively associated with said dual crank arm mechanism so that the foot engaging portions thereof move in arcuate paths between uppermost and lowermost arcuate positions, which arcuate paths are equidistant from a fixed pivotal axis provided on said frame, so that when the exerciser is in use in said stepping mode, one foot of the user will move upwardly between said arcuate positions while the other foot moves downwardly between said arcuate positions.
A dual mode exerciser, comprising:
- a frame configured to be supported on a horizontal surface;
- and
- a dual crank arm mechanism including left and right pedal members,
- each of said left and right pedal members having a foot engaging portion configured to support a foot of a user,
- said dual crank arm mechanism being selectively operable in a first mode or a second mode, wherein
- when said dual crank arm mechanism is operating in said first mode, the foot engaging portion of each of said pedal members moves in a generally elliptical closed loop path, and
- when said dual crank arm mechanism is operating in said second mode, the foot engaging portion of each of said pedal members moves in a generally up-and-down reciprocal arcuate path.
