Practice device, use of a practice device and method for checking the alignment of the longitudinal axis of a person's body

摘要

When golf is being played, the golf swing of a person (60) is decisive for the quality of the stroke. In order to obtain as good a golf swing as possible with a high hitting reliability and with precision, it is necessary to rotate the club with the arms (70) in a positionally fixed fashion about an imaginary axis through the head (68) and upper body (66). In order to monitor said positionally fixed rotation, it is generally necessary to consult a second person. Specifically, independent checking is possible only with difficulty. The object of the invention is therefore to provide a practice device (10) with which it is possible to check the position of the imaginary axis independently and without help from further persons in order to be able to practice the optimum golf swing even on one's own.;The object is achieved by a practice device (10) according to the invention. The practice device (10) has at least two lateral faces (18, 20) aligned substantially perpendicular to the underlying surface and with a distance between them that corresponds at least substantially to the human interocular distance. By positioning the practice device (10) on the underlying surface (28), it is therefore possible to visually determine even slight lateral deviations from a central ideal position above the practice device (10) by lateral faces (18, 20) that are correspondingly more or less visible.

1. A practice device for checking the alignment of a person (60), in particular a golfer, by a person (60) him/herself and relative to an underlying surface (28), comprising:
a many-faced basic body (12) which is basically in the shape of a polyhedron with at least partially flat outer faces (14) that are parallel in pairs and comprise at least two lateral faces (18, 20), a front face (22) and a rear face (24); and means for setting up on an underlying surface (28), at least the lateral faces (18, 20), the front face (22) and the rear face (24) being aligned at least substantially perpendicular to an imaginary plane running through the setting up means, wherein the two opposite lateral faces (18, 20) are arranged at a distance that corresponds at least substantially to a human interocular distance of between 5 cm and 8 cm, the two opposite lateral faces (18, 20) respectively having a wedge-shaped or V-shaped notch (34, 36) that respectively extends in a vertical direction.
