Resilient adjustable height golf tee

A tee assembly for teeing up a golf ball in a playing field, said tee assembly including the combination of:

• an elastomeric golf ball support having a golf ball support surface and an internally threaded base at opposite ends thereof, said elastomeric golf ball support being elongated by a distance sufficient to support a golf ball within a selectable range of elevations above such a playing field;
• a flanged base having opposed load-bearing surfaces for anchored support at an underlying site beneath such a playing field;
• an elastomeric shaft anchored against rotation about an elongated central axis thereof to said flanged base to resiliently extend in an upstanding manner toward such a playing field along a distance sufficient to correspond to said selectable range of elevations, said elastomeric shaft having external threads in mating engagement with said internally threaded base to resiliently restore said elastomeric golf ball support to the selected elevation above such a playing filed;
• and
• an abutment mounted on a protruding terminal end of said elastomeric shaft to prevent disengagement of said golf ball support from said elastomeric shaft.
