Patent Images
1. An end cap that is removably mounted on a sports stick having a hollow shaft, the end cap comprising:
- a knob having an opening and a cavity;
a bolt having a head coupled to and mounted in the cavity of the knob, and a threaded shaft portion extending through the opening in the knob;
a nut, for threading on the threaded shaft of the bolt; and
a compression plug operatively mounted between the knob and the nut and disposed about the threaded shaft portion of the bolt, wherein when the knob of the end cap is rotated, the compression plug is compressed between the knob and the nut and expands to contact one or more inside surface of the hollow shaft of the sports stick at a sufficient pressure to thereby generally firmly hold the compression plug of the end cap to the inside surface of the hollow shaft of the sports stick.
