Abstract

A device is used to limit the duration of a game on a tennis court. It releases the net which divides the court and renders the court unusable. The device is built into the posts which hold the tennis net. It has a guide (1) and a slide (2). The slide (2) has a pulley (3) around which passes the cable (4) which holds the net. The cable (4) is connected to a clamp (6, 7). The slide (2) is connected to a worm-drive (9) driven by a gear train (10, 11, 13, 15) and an electric motor (16). A time switch energises the motor (16) at the end of a set period of time. The motor (16) then pulls the slide (2) downwards and the net is released.
