Abstract
A stationary exercise bike that includes a foot-exercise mechanism that rotates and a hand-exercise mechanism that rotates. In addition to the rotational movement, both the foot-exercise mechanism and the hand-exercise mechanism simultaneously move in a reciprocating manner. The foot-exercise mechanism makes reciprocating upward and downward movements in a vertical plane and the hand-exercise mechanism makes reciprocation forward and backward movements in a horizontal plane. The height of the hand-exercise mechanism and the seat of the bike are adjustable, so that they may be positioned at a proper height and angle.
Claims6
A multi-functional stationary bike for gymnastic purposes, comprising:
- a bike frame having a forward frame, a rearward frame and a main body, said forward frame and said rearward frame being able to be raised and lowered for the adjustment of their height and a pair of C-clamps, each clamp positioned for securing and locking one of the respective forward frame and the rearward frame in place at the desired adjusted height, said bike frame further having an upper portion and a lower portion;
- a foot-exercise mechanism positioned at the lower portion of the bike frame, said foot-exercise mechanism having a base and a foot-gearing mechanism, said foot-gearing mechanism positioned for engaging the base when being rotationally driven, the foot-gearing mechanism further being carried by the foot-exercise mechanism for moving upwardly and downwardly in reciprocal movements about the base when the foot-gearing mechanism is driven;
- a hand-exercise mechanism horizontally carried by the forward frame and the rearward frame of the bike frame, the hand-exercise mechanism including a base and a hand-gearing mechanism positioned for engaging the base when rotationally driven by the user, the hand-gearing mechanism further being carried by the hand-exercise mechanism for gradually moving towards and away from the user when the hand-gearing mechanism is driven;
- an extension seat positioned at the upper portion of the bike frame above the foot-exercise mechanism, the extension seat including an adjustable movable rod and a seat, the seat carried by the movable rod for raising or lowering thereon for height adjustment;
- such that the foot-gearing and hand-gearing mechanisms each rotate and translate when driven by the user, and further such that the height adjustment of the forward frame and the rearward frame provides various operative heights and angles of hand exercise.
2 more elements
A stationary bike, in combination of:
- a bike frame including a lower portion and an upper portion;
- a foot exercise mechanism including a foot pedal shaft having opposite ends extending therefrom, said foot pedal shaft being carried by the foot exercise mechanism for rotational movement, said foot exercise mechanism further including a pair of foot pedals, each foot pedal being carried by a respective opposite end of the foot pedal shaft, and a foot gearing mechanism for engaging the foot pedal shaft, such that the application of force upon the foot pedals rotates the foot pedal shaft and moves the foot pedals in upward and downward reciprocal movements in a substantially vertical plane;
- a hand exercise mechanism including a hand pedal shaft having opposite ends extending therefrom, said hand pedal shaft being carried by the hand exercise mechanism for rotational movement, said hand exercise mechanism further including a pair of hand pedals, each hand pedal being carried by a respective opposite end of the hand pedal shaft, and a hand gearing mechanism for engaging the hand pedal shaft, such that the application of force upon the hand pedals rotates the hand pedal shaft and moves the hand pedals in forward and rearward reciprocal movements in a substantially horizontal plane;
- a seat carried by the upper portion of the frame substantially above the foot exercise mechanism;
- and
- such that the simultaneous application of force on the hand pedals and on the foot pedals rotationally moves said pedals and simultaneously moves both the hand pedals in the forward and rearward reciprocating movements in the substantially horizontal plane and the foot pedals in the upward and downward reciprocating movements in the substantially vertical plane, whereby the hand pedals and foot pedals each rotate and translate when driven by the user.
