Abstract: The assembly is a swim exercise device to be secured around a support structure near the surface of water and includes a length of cord (12) with two loops (22, 34, or 134) formed at each end. The first loop (22) is formed by a first guide means (14) being made of flexible sheet material which is bent to align pairs of holes (16, 18) for threading of the cord (12) therethrough which naturally resists such folding motion to remain biased toward flat which grips and prevents movement of the cord (12) therethrough. The second loop (34, 134) is formed by a second guide means (38) or a flexible strap (54). The cord (12) is positioned around a support structure and the first loop (22) is threaded through the second loop (34, 134) and is pulled taut to secure the assembly near the surface of water for exercising. Variable resistance is obtained by using an elastic cord (12) and variable elasticity is accomplished by adjusting the length of cord (12) between the first loop (22) and the second loop (34, 134).

Abstract: A portable appliance (10) which is worn by the user to exercise a body joint includes an articulating frame (12) composed of a pair of laterally, spaced-apart pivot arms (14a, 14b) connectible to a first limb of the body joint and pinned to a second pair of spaced-apart pivot arms (16a, 16b) connectible to the second limb of the body joint. A rotatably actuated, fluid cylinder assembly (22) is mounted on the first pivot arms (14a, 14b) on the extendible side of the body joint. The cylinder assembly (22) includes a piston (24) threadably engaged within an elongated piston rod (26). A transmission system transmits the relative rotational movement between the frame arms (14a, 14b) and the frame arms (16a, 16b) to the piston rod (26) thereby to actuate the piston (24). Adjustable flow control devices control the flow of fluid within the cylinder assembly (22) to apply isotonic, isokinetic or dynamic resistance to the flexing or extending of the body joint being exercised.

Abstract: The incorporation of a wrist exercising device in conjunction with the handlebar of a bicycle which permits the exercising device to be operated as the bicycle is being operated. The exercising device can be pivoted against a spring bias relative to the handlebar in either a clockwise or counterclockwise direction. The movable portion and the fixed portion of the exercising device are interlocked together through a cooperating flange and groove assembly. This interlocking arrangement prevents lineal separation of the parts of the exercising device but yet permits rotation of a portion of the exercising device relative to another portion of the exercising device.

Abstract: The invention relates to a physical exercise apparatus comprising three nested frame elements mounted inside one another for rotation about axes offset by 90.degree. from one another. The thus established gimbal mounting of the frame elements permits a person occupying the innermost frame element to assume any angular position in space solely by displacing his weight to thereby fortify his muscles an improve his sense of equilibrium.
