摘要:
A batting tee supporting a ball has a base, a telescoping post having a first tube, a second tube, a rod, and a flexible ball holder secured to the telescoping post. Wearable bushing assemblies enable friction between components of the tee to remain at least substantially constant over a range of tolerances, even as bushings wear. Each bushing assembly includes a bushing holder, a C-shaped spring positioned around at least a portion of the bushing holder, and a C-shaped bushing constructed of wearable material and positioned at least partially around an outer periphery of the C-shaped spring. Each bushing assembly is positioned into a respective tube such that the C-shaped bushing contacts an inner surface of its respective tube. The C-shaped spring provides an outward radial force for applying friction between the C-shaped bushing and the inner surface of the tube when one component is axially moved relative to another.
