发明名称 Tennis guide training target
摘要 A tennis guide training device utilizes an actual size tennis ball which is secured to an axially adjustable elongated mounting stem. The mounting stem is adjustably secured to a clamping device which is adapted for engagement with the top edge of a conventional tennis net. In a first embodiment, the clamping device is in the form of a resilient spring clip which is provided with a threaded mounting socket. The adjustable stem is formed from a coil spring which is received within the threaded socket. The height of the tennis ball target above the top net edge may be adjusted by screwing the mounting stem into or out of the threaded socket. In a second embodiment, the clamping device is in the form of a resilient clip which is provided with a mounting socket having an axial bore for the reception of a mounting stem. The mounting stem is formed from a cylindrical rod of a rigid material and is secured in adjusted axial position within the mounting socket by a thumb screw. The device serves as a training aide to enable practicing tennis players to develop a better union of visual and motor skills.
