A cycle exerciser having a one-way sprocket and a pair of one-way pinions disposed on a compound shaft. The one-way sprocket is rotated by a pedaling mechanism through a chain. The one-way pinions are respectively rotated by a pair of lever arms through a respective toothed element and a connecting mechanism. The toothed element engages and rotates the one-way pinion. The connecting mechanism comprises a substantially cylindrical swivel block and a torsional spring. The swivel block has a rim portion for fixedly securing to the toothed element and a protruding swivel shaft for telescopically receiving one end portion of the lever arm. The connecting mechanism, which is fixed to the toothed element by the rim portion thereof, connects to the lever arm in such a way that the lever arm can perform oscillatory and swiveling movement like rowing boats. The compound shaft is arranged to drive an energy absorbing wheel.
A golf swing training apparatus including a base; a strut having one end supported by the base; a support retained by a portion of the strut opposite to the one end, the support adapted to project between a golfer's legs and to engage the groin regions thereof; and a rotational coupling allowing rotation of the support means in response to rotational movement of the golfer's hips. This structural combination desirably provides a steady base, allows the hips to pivot around a near vertical axis and keeps the groin area fixed in space.
A stationary exercise device includes a pair of poles having an upper end rotatably secured to a base at a pivot rod and a pair of brackets slidably engaged on the poles for allowing the brackets to be moved up and down along the poles and to be rotated about the pivot rod. A pair of foot supports are secured to the brackets and moved in concert with the brackets. A crank is rotatably secured to the base and coupled to the foot supports for rotating the foot supports about the pivot rod and for moving the foot supports up and down along the poles such that the foot supports may be caused to move along an elliptical path. A pair of handles are secured to the brackets for supporting the upper portion of the user.
The invention concerns a sporting and exercise apparatus movable by muscular force consisting of a frame having for the user an elongated platform supported by at least two wheels and of a mechanical hand-lever drive for converting a lever motion into a rotary motion of at least one of the wheels. The lever drive has at least one hand lever hinged on the frame which actuates either two racks, at least one gear segment or a chain/segment drive which act upon gears supported on a driving axle so that the racks, segment or the chain, when the lever is moved in one direction, actuate one gear to rotate clockwise and another gear counterclockwise, each gear being supported on the driving axle via a free-wheel unit.
The invention concerns a sporting and exercise apparatus movable by muscular force including a frame having for the user an elongated platform supported by at least two wheels and a mechanical hand lever-drive for converting a lever motion into a rotary motion of at least one of the wheels. The lever drive has at least one hand lever hinged on the frame and having a toothed segment interconnecting a first and a second rotatable shaft each having a first and a second gear in which each first gear is supported on the shaft by free wheel units and in which a drive pinion is fixedly connected to the second shaft so that either forward or rearward movement of the hand lever will actuate one of the first gears and impart drive torque in the direction of movement of the apparatus while the other first gears torque is limited due to the action of the corresponding free wheel unit.
A front wheel drive bicycle exercise device including a front wheel and a reciprocating handlebar assembly attached to a frame. A clutch and a mechanical advantage device are utilized to drive the front wheel of the bicycle in response to the reciprocative displacement of the handlebar assembly.
