Attorney, Agent or FirmInternational ClassA63B 067/02AbstractA putter training device for judging a speed of impact of a golf club head upon a golf ball and including an elongated structure with a first guide wall and a second spaced apart and substantially parallel extending guide wall. A golf ball placement position is located at a first interconnecting end of the spaced apart guide walls. An adjustable and cross wise extending passageway with pivoting flaps is located proximate a second interconnecting end and determines a selected width for allowing passage therethrough of a golf ball which is struck at said placement portion and travels along the elongated structure between the first and second guide walls. A sensor circuit includes first and second pairs of spaced apart sensors mounted in opposing fashion and at spaced apart locations to the first and second guide walls. A counter assembly including a logic circuit interfaces with the sensor circuit to signal start and stop positions of the sensor circuit dependent upon first and second travel positions of the golf ball. A digital to analog converter is communicable with the logic circuit and converting an incremented output from the sensors for subsequent presentation on a display circuit. A power supply communicates with the sensor circuit, counter assembly, digital to analog converter and display circuit for supplying an electrical power input.Field of SearchProjectile addressing surface and target, or distance marker (e.g., course, putting green with cup, driving range, miniature golf course, etc.)Electrical sensor or electrical indicator responsive to swingable implement or projectile Sensor is projectile responsive (e.g., free-flight detection means, etc.) Projectile in receiver indicator Including sensor responsive to projectile on addressing surface or in flight (e.g., tee-target time detection, etc.) Non-earth fairway And obstacle (e.g., miniature golf course windmill, etc.) Target or obstacle (e.g., putting hole, hole marker, sand trap, etc.) Projectile responsive sensor (e.g., target impact indicator, etc.) Electrical sensor Projectile receiving aperture (e.g., goal opening, etc.) Aperture forming surface forms plane parallel to support surface Moving projectile responsive sensor or indicator Electrical Accesory device located on projectile addressing surface (e.g., tee block, direction indicator, etc.) Golf | |
