Abstract:
1. A multi-exercise rotary device, comprising: at least one elongate body-supported member extending generally along a longitudinal axis, said body-supported member having a first end adapted to be supported by a portion of the body of a user of the device, and a second end opposite the first end; at least one rotating member having a longitudinal axis that is at least semi-rigid, said rotating member including a planar surface adapted and intended to present a substantial air-resistance effect which is noticeable to the user in response to rotation of said rotating member; a rotary mechanism for coupling the rotating member to a point on the body-supported member which is near the second end thereof, said rotary mechanism allowing rotational movement of the rotating member in a direction about the longitudinal axis of the body-supported member; and a device for constraining the angular movement between the longitudinal axis of the rotating member and the longitudinal axis of the body-supported member to be substantially only in a predetermined plane axially aligned with the body-supported member, and for constraining said plane from twisting with respect to the longitudinal axis of said body-supported member; wherein said rotating member includes an airfoil having said planar surface thereon, and an angle adjustment means operable for making a noticeable change to the user in an amount of air being displaced by the airfoil to said user, said airfoil being adjustable by said angle adjustment means so as to set an angle that the planar surface of the airfoil makes with respect to the direction of rotation of the rotating member to one of a plurality of different angles, and thereby present a noticeably different one of a plurality of selectable air-displacement effects to the user in response to said rotational movement.
