ABSTRACT:
An adjustable footrest for use on a chair to comfortably accommodate the feet of a user. Defined on the underside of the mounting plate is an elongated hollow housing which receives the essential moving elements of the footrest mechanism. Positioned within the hollow housing is a gas cylinder that contains an actuator pin located on a piston at the upper end of the cylinder. Located near the bottom of the hollow housing is a pair of outwardly projecting legs to which is pivotally mounted an elongated leg. A portion of the leg is positioned within the housing and is pivotally mounted to the connection end of the gas cylinder. The other end of the leg extends away from the hollow housing and terminates in a tranversely positioned footrest. Pulling the handle in an upward direction presses the actuator pin within the gas cylinder, thus releasing the piston. While the user maintains the handle in its top position, the user may then exert a downward force on the footrest. Which causes the bottom leg to pivot and, thus, urge the piston into the cylinder. When the footrest is in a desired position, the handle is released. The footrest maintains a rigid position throughout its range of movement by having the gas cylinder filled with oil on the compression stroke.
