发明名称 GOLF TRAINING IMPLEMENT IN COMMON USE AS STRETCHING BOARD
摘要 PROBLEM TO BE SOLVED: To a golf training implement for training shots on slopes which is easily usable in a golf training range or at home, is simple in structure, may be inexpensively produced and is high in safety and use effect. SOLUTION: This golf training implement has a bottom late 3 having a first bearing spherical surface part 1, an approximately circular top plate 4 having a second bearing spherical surface part 2, a spherical claming member 5 arranged at the rear surface of the first bearing spherical surface part 1 and a connecting member 6 for connecting the top plate 4 and the claming member 5. When the connecting member 6 is tightened, the first bearing spherical surface part 1 and the claming member 5 abut on each other and the first bearing spherical surface part 1, the second bearing spherical surface part 2 and the claming member 5 are superposed triple and are clamped to each other in tight contact. The clamping of these parts is the tripe structure of the members having wide areas and, therefore, the inclination of the top plate is extremely securely fixed by large friction resistance at the wide area. Even if the player rides on the top plate, there is no danger that the connecting member 6 recesses to the top plate 4 and, therefore, this implement is excellent in terms of safety as well.
