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.
