发明名称 Tennis service practice court with recovering and collecting means
摘要 A practice tennis court for practicing serving the tennis balls consists of the complete forward or receiving part of a tennis court back to the net and only the service area beyond the net. Immediately behind the service area is an end net or other backstop to stop the balls without rebounding. At the net, there is a continuous rake extending across the court for sweeping used balls to the back of the service area. At the rear end of the service area adjacent to the collection net is a trough with an endless belt running from side to side to remove the spent balls to a collection point. At the end of use of the court or after play of a selected number of balls, the rake is moved from the net area to sweep the spent balls underneath the collection net and into the trough for removal. A preferred arrangement would provide several of these courts side by side with the collection trough and belt extending across all of the practice courts.
