Abstract: An improved height adjustment mechanism for a batting tee uses an adjustment screw that attaches a compressible washer assembly to the bottom of an inner telescoping member to spread a compressible washer, thereby increasing the diameter of the compressible washer assembly and consequently adjusting internal friction between the washer assembly and the inner surface of an outer telescoping member to a desired amount necessary to hold the inner telescoping member stationary within the external telescoping member while the tee is being used while still allowing manual height adjustment of the batting tee as may be desired by the batter.

Abstract: An improved batting tee uses an elongated split washer to provide friction between telescoping parts in the stem without requiring tightening adjustments by a user, an elongated rounded grommet at the top of the tee to provide stability for the grommet and protection for the ball holder against cuts made by the bat hitting the ball holder against the top end of the innermost telescoping member, and a ball holder made from a wound, flexible material that retains its shape and resiliency without requiring a threaded member to hold the windings together.

Abstract: A durable batting tee utilizes an adjustable compression nut to provide a range of adjustable heights for extensible vertical pipes, and an inverted flexible cone atop the vertical pipes upon which a baseball is placed for hitting, such that the compression nut will maintain the rubber cone at a predetermined height, and the flexible cone will maintain its integrity throughout a lifetime of repeated strikes with a baseball bat. The baseplate is dimensioned and weighted to hold the tee upright during normal use, and to permit tipping when subjected to errant swings of a bat.
