Abstract: The present invention pertains to a golf tee comprising a stem portion and a top portion connected to the stem portion, the top portion includes an upper surface that opposes the stem and having a convex shape, free of an adhesive layer or material that anchors the ball on the upper surface against uneven ground. The golf tee minimizes friction and other impeding forces between the tee and the ball by reducing an area of contact between the tee and the ball, while preventing the player from installing the golf tee other than vertically into the ground, or horizontal to the Earth's surface, thereby preventing the golf player from having to alter his or her posture and stroke according to the mounting of the ball.

Abstract: A golf tee has a head contoured to balance a golf ball thereon, a point for insertion into a ground surface, and a stem joining the head to the point, the stem providing an enlarged medial portion relative to a proximal portion near the head and a distal portion near the point. The stem has a continuous curvature between the head and the point and joins the head to the point such that the point inserts into the ground surface at an angle that facilities ejection of the tee from the ground surface when the curvature is placed outward relative to a direction of a ball strike force.

Abstract: A golf tee includes a ball seat portion on which a golf ball is placed; and a rod-shaped support shaft portion formed downward from the ball seat portion. The support shaft portion has a projection that is laterally formed on and projected from the support shaft portion. The ball seat portion and the support shaft portion are formed plane-symmetrically on a single plane including a central axis line of the support shaft portion and a point of the projection. In the single plane, a virtual plane including contact portion that contacts with a golf ball when the golf ball is placed on the ball seat portion and a central axis line of the support shaft portion form an obtuse angle on one side of the axis line and form an acute angle on the other side of the axis line.

Abstract: A low ground resistance golf tee for insertion into a playing surface to support a golf ball above the playing surface to be struck by a golf club launching the golf ball in a flight direction is provided. The golf tee includes a body having an impact side, a release side, an insertion end, and a ball support end. The golf tee has a low exit resistance region that includes a low exit resistance region insertion edge for penetrating and separating the playing surface to create a preferred exit path for the low exit resistance region upon impact by the golf club. The golf tee further includes a stem region located between the low exit resistance region and the ball support end, which is designed to be displayed above the playing surface. Upon impact, the golf tee pivots forward in the flight direction with minimal resistance from the playing surface.

Abstract: An improved angular golf tee made from a single unity piece of plastic which defines an elongated, ribbed body and a tapered structure with a shoulder. Distal ends of the ribbed body terminate in the shoulder and in a thin ring, respectively. Properly inserted into the earth, the tapered structure is disposed vertically; and the ribbed body is bent away from the vertical by an angle of about 30 degrees. This configuration allows one to direct the upper end of the ribbed body toward himself, so that there is less chance of the tee and any golf ball resting thereon being hit simultaneously. The ribbed body further defines a pair of open, elongated cavities between which protrudes an elongated, vertical, flat rib. The pair of elongated cavities and rib are capped by the thin ring which terminates upwardly in a horizontally-disposed rim. Sloping inwardly from the rim, the ring defines a concave hollow, whose curvature closely matches that of the exterior surface of a standard-size golf ball.
