Abstract: The adjustable tricycle of the present invention encompasses a body having a front and a rear, a front wheel rotatably attached to the front of the body, a handle bar member pivotally connected to the front of the body for steering the front wheel, a pivotable link mounted on the body; a pair of rear wheels rotatably mounted on the pivotable link, and a positioning device pivotally connected to the pivotable link for controlling the position of the body with respect to the rear wheels. The pivotable link and pivoting positioning device form an angular positioning device which controls the position of the body with respect to the rear wheels. In the preferred embodiment, the positioning device is a support bar capable of interlocking the rear end of the body in at least two locations.

Abstract: An exercise apparatus comprising a frame, a pivot arm mounted on the frame, a resistance mechanism, preferably an elastomeric torsion member, and a positioning element which allows the pivot arm to be pivotally adjusted with respect to the frame, independent of the resistance element, so as to vary the neutral position of the pivot arm. The preferred embodiment may also comprise a shaft mounted to the frame for conveying torque to the elastomeric torsion member and a support arm mounted to the frame to oppose rotation of the elastomeric torsion member about the shaft. In one embodiment, the exercise apparatus takes the form of a weight bench. In a second embodiment, the exercise apparatus is a home gym.
