Patent number: 7104900Abstract: A golf mat similar to the type used at a driving range, including a hole for inserting a golf tee, with the addition of a pressure sensor (transducer) embedded in one corner of the mat, sandwiched between a top artificial grass and a bottom rubber backing of the mat, for use in activating an alarm when the golf club head strikes the area just behind the ball, above the pressure sensor, before striking the ball. When the golf club strikes the area above the sensor, an electrical signal is sent to the input of a timer circuit, which then provides a signal of a few seconds in time to the input of a visible alarm. Lines are included on the top surface of the mat to mark off the boundaries directly above the pressure sensor so a golfer will not step in this area and set off a false alarm. In use, when the golfer makes a good swing with the club head striking the ball solidly, without hitting the ground first, then the alarm will not flash a light.Type: GrantFiled: August 15, 2003Date of Patent: September 12, 2006Inventor: Marc Finley

Patent number: 5885164Abstract: This invention relates to a golf practice aid which allows the golfer to estimate the distance and direction of a struck ball, while using a limited space, not compromising the feel and rotation of the ball and allowing for the golf ball to come to rest near its original striking position. In the preferred embodiment of the invention, a mass freely rests upon a flat surface. A horizontal bar is inserted and secured through a hole through the mass, extending equidistantly from the center of gravity of the mass. A cord is secured to spaced-apart points on the bar, preferably at opposite ends of the bar. A golf ball is secured to the cord, by virtue of the cord passing through a hole through the center of the golf ball, with keepers to prevent the golf ball from sliding any significant distance along the cord. The hole through the golf ball preferably is large enough to allow the ball to spin on its axis around the cord when struck.Type: GrantFiled: June 24, 1998Date of Patent: March 23, 1999Inventor: W.

Patent number: 5762562Abstract: A golf practice device has an angled, curved or straight frame made of tubular steel on which two anchor points are formed between which a rope is tensioned. A golf-ball-like body is tracked along the rope by means of a flexible connector. A strike plate is located on the rope in the vicinity of an upper anchor point. The frame and the rope form a closed tensioning system which generates vibrations in the rope when the body hits the strike plate, where the magnitude and direction of the amplitudes of said vibrations are a function of the point of contact between the body and the strike plate. The vibrations of the rope affect the type of movement of the struck body during its return to the first anchor point such that the user can draw conclusions about the nature of his golf swing.Type: GrantFiled: December 27, 1996Date of Patent: June 9, 1998Assignees: Dietor Hoch, Josef Kopf, Bernhard Kopf, Till TiedgeInventor: Till Tiedge

Patent number: 5746667Abstract: A golf tee comprising a vertical member adapted to be struck into the ground, a transverse member pivotally engaged with the end of the vertical member and adapted to be adjustably moved angularly with respect to the vertical member and to retain its angular position therewith after such movement, and a string engaged at one end with the transverse member and engaged at the other end with a suction cup for engaging and supporting a golf ball above the ground. The transverse member may be pivotally moved to suspend the golf ball at the desired distance above the ground. When the golf ball is then struck with the head of a golf club, it encounters less impedance to true straight flight than a golf ball struck from a conventional tee. Longer driving distances can be achieved than when driving from a conventional tee. Moreover, there is less danger that the golf club will dig up a large divot of top soil than when the golf ball is struck from a conventional tee.Type: GrantFiled: March 24, 1997Date of Patent: May 5, 1998Inventors: Paul M.
