Abstract
A golf tee comprising a rotatable support member seated so as to be submerged within a hollow head portion of an elongated body with the side surface of the rotatable support member engaged by an O-ring to the internal side surface of the hollow head portion. A pointed bottom member is removably connected to the lower end of the elongated body. An elastic element extending through an axial hole in the elongated body connects the rotatable support member to the pointed bottom member. Manually rotating the rotatable support member provides for storing energy in the elongated elastic element such that when a golf ball is placed on the rotatable support member the golf ball can be made to slowly rotate about a vertical axis to thereby provide a moving object for holding the attention of a golfer as he addresses and drives the ball.

A golf tee comprising:
- an elongated body including a hollow head portion with an axial bore providing an internal sidewall, a lower end, and an axial hole extending from the axial bore through the lower end thereof;
- a pointed bottom member having an upper end removably connected to the lower end of said elongated body;
- a rotatable support member having a lower end seated within said hollow head portion and having a sidewall spaced with a clearance from the internal sidewall of said hollow head portion;
- annular friction means positioned to lie in the clearance space between said rotatable support member and said hollow head portion;
- and
- an elastic element extending through the axial hole of said elongated body and connecting the lower end of said rotatable support member to the upper end of said pointed bottom member;
- whereby said rotatable support member can be manually rotated relative to said hollow head portion to store energy in said elastic element which can thereafter be used to rotate said rotatable support member and a golf ball carried thereon about a vertical axis.

A golf tee comprising:
- an elongated body including a hollow head portion, a lower end, and an axial hole extending from the hollow head portion through the lower end thereof;
- a pointed bottom member having an upper end removably connected to the lower end of said elongated body, said pointed bottom member provided with a hook on the upper end thereof;
- said hollow head portion formed with an upper axial bore and an intermediate axial bore having a diameter smaller than said upper bore, and a bottom shoulder;
- a rotatable support member including an upper portion, a cylindrical intermediate portion of smaller diameter than said upper portion, and a cylindrical stem portion having a smaller diameter than said intermediate portion and a bottom surface, said cylindrical stem portion provided with a hook on the bottom surface thereof;
- an annular resilient frictional means fitted about said cylindrical stem portion, the outer diameter of said frictional means being normally slightly larger than the diameter of said intermediate bore;
- said rotatable support member being mounted within said hollow head portion with the bottom surface of said cylindrical stem portion seated adjacent the bottom shoulder of said intermediate bore, and the upper portion and cylindrical intermediate portion respectively spaced with a clearance from said axial bore and the intermediate bore of said hollow head portion, whereby only the annular resilient frictional means contacts the intermediate bore;
- and
- an elastic element extending through the axial hole of said elongated body and connecting said hook on the upper end of said pointed bottom member to said hook on the bottom surface of said cylindrical stem portion;
- whereby said rotatable support member can be manually rotated relative to the hollow head portion to thereby twist said elastic element and store energy therein thereby enabling said rotatable support member and a golf ball carried thereby to be thereafter rotated relative to the hollow head portion by the untwisting of the elastic element at a rate determined by the annular resilient frictional means.

A gold tee comprising:
- an elongated body including a hollow head portion having an axial bore providing an internal sidewall and a bottom shoulder, a lower end, and an axial hole extending from the axial bore through the lower end thereof;
- a pointed bottom member having an upper end removably connected on the lower end of said elongated body;
- a rotatable support member having an axial body with a sidewall and a lower end;
- and
- resilient friction means securely encircling and slightly protruding from the sidewall of said rotatable support member;
- said rotatable support member positioned within said hollow head portion with its lower end seated adjacent the bottom shoulder of said axial bore and with its sidewall spaced with a clearance from the internal sidewall of said hollow head portion such that only the resilient friction means engages the internal sidewall;
- an elastic element extending through the axial hole of said elongated body;
- and
- means for connecting the elastic element between the lower end of said rotatable support member and the upper end of said pointed bottom member;
- whereby said rotatable support member can be manually rotated relative to said hollow head portion to store energy in the elastic element which can thereafter by used to slowly rotate said rotatable support member and a golf ball carried thereon relative to the hollow head portion.
