  • Patent number: 5827126
    Abstract: A golf putting practice device which is adapted to be worn on the wrist of the user, which includes a housing containing an alarm system including a sensor, an operating lever pivotally connected to the housing and biased in a predetermined neutral position, a switch lever fixed at one end to the operating lever in the neutral position and extending into the housing in close proximity to the sensor, whereby when the operating lever and associated switch lever are moved from the neutral position, as a result of a bending of the wrist, the switch lever engages the sensor which activates the alarm system, which signals the bending defect in the putting stroke.

  • Patent number: 5478078
    Abstract: A golf putting practice device includes a C-shaped body member having a rear surface with a pressure sensitive adhesive backing for removably attaching the guiding device to the striking face of a golf putter and a front surface having a pair of elongated vertical rails disposed on both inside edges of a pair of vertical legs, two pairs of pins disposed near the ends of the rails, and a marker pin disposed on the center of a bridge connected to both legs whereby when properly stroked with the golf putter, the rails and pins allow a golf ball to pass therebetween and strike the sweet spot through an aperture in the C-shaped body member, thereby causing the golf ball to roll straight in the direction of the intended target and when the golf ball is improperly stroked, it strikes the rails or pins and is turned away from the target.
