Self contained putting aid

A self contained putting aid, including an elongated rail having a generally U-shaped cross section. An elongated, flexible aiming strip is connected to the rail through a parallelogram linkage so that the strip can be moved from an operative position, where it is in spaced, parallel relation to the rail, to an inoperative position, where it is located within the rail. An end of the strip is formed with a hole to support a golf ball, and a movable backstroke guide is mounted on the strip and serves as a guide for the length of the backstroke. A plurality of adjustable holding members project downwardly from the rail and are adapted to engage a carpet or other putting surface to prevent movement of the rail during the putting stroke.
