ABSTRACT:
An adjustable height basketball backboard support system wherein a retainer is attached to an adjustment link in order to maintain the adjustment link adjacent to the support member during the adjustment process. The retainer consists of a slide which rides on a guide or rail. The slide includes two parallel legs, although one leg can be used, which extend to and form an U-shaped terminal end. The slide can also consist of a loop configuration. The guide or rail is positioned on the support member or can even be the support member. The slide's legs curve around the guide which can be a bracket attached to the support member or the support member itself. The retainer can be both the retaining mechanism and the mechanism which locks the adjustment link to the support member or it can be a separate element which only serves as the retaining mechanism. The interaction between the retainer and the bracket or support member prevents the adjustment link from swinging away from the support member during the adjustment process.
