Adjustable basketball backboard support system

摘要

A height adjustable basketball backboard is pivotally attached to a support member by a parallelogram linkage. An adjusting link is a pivotally attached to an extension on one of the parallelogram links, is adjustably mounted to the support member and is weighted to act as a counter balance force to the weight of the basketball backboard to reduce the effort necessary to raise and lower the basketball backboard. A conversion kit for converting existing basketball backboard support system to the above referenced adjustable counter-weight design and methods for adjusting the counter-balance effect of the weight are disclosed.
