The device is made from aluminum tubing and is inexpensive to manufacture and to transport. The device has no moving parts to injure users or to reduce its service expectancy. The preferred embodiment is sized for use by children near five feet, ten inches in height.

Abstract: A dual exercise device includes a frame having an elongated seat bar and a vertical support at the front end of the seat bar. Struts intersect and are connected pivotally to the seat bar near the seat of the bar. The struts have an upper back supporting portion and a lower leg portion with a wheeled bottom end. The back supporting portion moves rearward when the upper body of the user inclines rearward so that the lower leg portion moves forward against an extension spring provided between the leg portion and the rear end of the seat bar. A steel rope extends along the seat bar and has a portion extending upward from the front side of the frame and another portion extending and being fixed to the wheeled bottom end from the rear side of the frame. The upward portion is provided with a handle rod to be pulled by the user. A bicycle wheel associated with a pair of paddles is mounted on the front support.

Abstract: A balancing apparatus having a surf board, an upstanding support post and a main universal joint connected in-between the bottom of the surf board and the top of the support post.

Abstract: The invention is a moving ladder exercise device 10 comprising a base 11, moving ladder assembly 12 and retarder assembly 14 using a microprocessor 15 to control retarder speed. The operation of the moving ladder requires the operator to climb the ladder thereby driving the ladder with his body weight. Maximum speed of the ladder assembly 12 cannot exceed the speed of the retarder assembly 14 due to the unidirectional clutch 33 and worm-drive assembly 32. Sensors 17 monitor heart rate of the operator and sensor 16 monitors ladder speed. Sensor output to microprocessor 15 provides feedback which allows the microprocessor to adjust retarder assembly speed so that the desired heart rate is reached and maintained.

One leg is rotatable about an upwardly inclined axis along a first angle and the other leg extends at a different angle from the apex. The free end of the other leg supports a platform for supporting the skier's feet. The other leg together with the platform swing in pendulum fashion about the apex and seek an equilibrium position under the action of gravity when the skier is not on the platform.

Abstract: A foot pedal assembly for an exercise machine. The foot pedal assembly includes a foot pedal or base having a longitudinally extending upper surface on which the user's foot rests and a strap the ends of which are coupled to opposite sides of the foot pedal so that the strap extends horizontally across the pedal in a position to maintain the user's foot in place. One end of the strap is coupled to a rotatable, square shaft which extends longitudinally, adjacent to a portion of one side of the foot pedal. The square shaft extends through an aperture in a knob with a one-way clutch being disposed between the shaft and the knob. The one-way clutch engages when the knob is rotated in a first direction to transmit rotation to the shaft to wind the strap thereabout tightening it about the user's foot. A release lever is hinged at one end to the foot pedal and extends horizontally underneath the foot pedal and square shaft.

Abstract: The invention provides an exercise cycle with a stationary frame, a seat, a pedal mechanism, and a rotating wheel. Resistance is offered to the rotating wheel by an adjustable brake assembly. A handle bar assembly is pivotally mounted to the frame to move back and forth toward and away from the user positioned on the seat. A locking mechanism is associated with the handle bar assembly, so that with the locking mechanism in a first position, the handle bar assembly is precluded from pivoting. With the locking mechanism in a second position, the handle bar assembly is allowed to pivot toward and away from the user. A resistance mechanism is also associated with the handle bar assembly.

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.

Abstract: An exercise machine in the nature of a stationary cycle exerciser. The exercise machine replaces the conventional crank-arm rotary pedal drive with reciprocating treadles or pedals connected to drive a work-utilizing device at a substantially uniform rate throughout the entire input stroke by the user. Hand-operated levers are also provided for manipulation by the user, and movement of these levers is coupled to the working load.

Abstract: An exercise apparatus having a pair of arms which are rotatable about a horizontal axis permitting a user to grasp handles attached thereto and to windmill the user's arms so that the arms of the machine will rotate about an axis extending through the shoulder joint connected to the user's arms.
