发明名称 Ball launching racket
摘要 An improved ball launching racket has a flexible net disposed within a central opening of a racket by a plurality of removable clip and elastomeric band assemblies. The construction of the clip facilitates expedient mounting and removal of the elastomeric bands, thereby allowing a user to expeditiously change the tension in the net, which in turn, changes the launching characteristics of the ball launching racket. The clip construction promotes usage of elastomeric bands that are free from apertures or slits, so that stress concentration points within the elatomeric bands are eliminated, increasing the useful life of each band.
