  • Patent number: 4336940
    Abstract: The golf tee holder includes a generally cylindrical body for reception of an inserted golf tee. The holder is retained against displacement by a tether shown attached to a ground inserted anchor. The body of the tee holder is shouldered at its upper end for confinement of the tee head. An annular groove about the holder body permits winding of the tether thereon in a convenient manner. Lengthwise grooves in the holder body slidably receive the legs of a bifurcated anchor which legs also prevent unwinding of the tether during non-use of the holder. The holder body is slotted at its upper end to facilitate tee insertion and removal.
