Abstract: A golf tee is provided, including a head portion, a neck portion, a stem portion, and a tip portion. The head portion is provided on a top of the golf tee and having a right-left symmetry. The neck portion is extended from the head portion and having a the right-left symmetry. The stem portion is extended from the neck portion and having a broken right-left symmetry. The tip portion is extended from the stem portion and configured for being pushed into a ground. The stem portion provides top-down and right-left aerodynamic unbalances to the golf tee, such that the golf tee rotates about a middle portion much more rather than flies away when the golf tee receives an external impact.

Abstract: A golf tee has a stake made of a first material and a crown made of a second material more flexible than the first material, in which the crown is overmolded over the stake. The crown and the stake can have corresponding projections. The stake can have projections to allow the crown and the stake to hold together better.

Abstract: Disclosed is a golf tee foldable, through rotation, in a direction of a drive swing to prevent breakage and loss and increase the drive shot distance. The golf tee comprises a ball platform; a supporting pillar; a coupling ball; and a ball coupling portion having a fixation pin. The ball coupling portion has two quarter-spherical shells symmetrically facing each other, separated by a contoured crevice of a uniform width defined by two opposing top edges of the shells. The two shells define a generally hemispherical receptacle for holding the coupling ball therein, which is open partially through the crevice and through a horseshoe-shaped bottom opening formed by two bottom edges of the shells. The crevice is sized and configured such that at a drive swing, the supporting pillar, being restricted by the two shells, moves only along the crevice, and thereby rotates and folds only in a single plane.

Abstract: This invention includes a golf tee portion with a shaft and two ends. One end of that portion includes a ball receiving end and one end includes a cavity portion for receiving a magnetic material. There is a cylindrical ball marker portion that goes between the golf tee portion and the base and is attracted to both. Last there is a grounded cylindrical base with two ends. One end can include a stem or series of stems so it can adhere in the ground, and one end is equipped with two cavities. One cavity is larger for placing a magnetic material which is attracted to the golf tee portion, and the removable ball marker, and a smaller cavity for magnetic material so the material in the larger cavity is held but removable. This design allows less friction on golf drives, and dual usage as a ball marker on the green.

Abstract: A golf tee apparatus for altering a golf ball's launch angle from an initial launch angle to a final launch angle, and for simultaneously imparting a spin for increasing the ball's roll distance. The apparatus includes a penetrating element for inserting the tee into a surface. A stem extends from the penetrating element, and a platform element extends from the stem. The platform element includes a ball setting surface and an impact surface, the impact surface extending from the ball setting surface at an angle.

Abstract: Apparatus and methods for using a plurality of golf balls to train a person to swing a golf club are described. In accordance with one aspect of the present invention, the apparatus includes a ramp, a golf ball holder and a trigger, which may be mechanical or electrical. The ramp conveys the plurality of golf balls, one at a time, from a first end of the ramp to a second end of the ramp. At least a portion of the ramp is angled downward from the first end to the second end. The holder contains the plurality of golf balls. It is arranged near the first end of the ramp to release one of the plurality of golf balls at a time onto the ramp. The holder further has an input. The trigger is connected to the input of the holder and arranged so that it can sense the golf swing, wherein when the trigger senses the golf swing, it triggers the input of the holder to cause the holder to release one of the plurality of golf balls into the ramp.
