This product is a golf training device used for practicing golf swings. As shown in the reference diagram indicating the names of each part, it has two guides: a first guide in the shape of a straight rod and a second guide in the shape of a semicircular arc, which serve as guides during the swing. The first and second guides are attached to a platform, whose orientation can be freely adjusted relative to a plate-like part placed on the ground. The platform consists of a base fixed to the plate-like part and a spherical sliding part fixed to the first or second guide, with the top surface of the base having a spherical recess. The spherical sliding part is slidably joined to the top surface of the base by magnetic force. The second guide is held in place by a clamp and attached to the sliding part of the platform via the clamp. By manually moving the first or second guide while the plate-like part is placed on the ground, the sliding part of the platform can be slid relative to the top surface of the base.

These features allow the axial orientation (posture) of the first guide and the orientation (posture) of the arcuate surface of the second guide to be adjusted to any orientation (up / down, left / right, front / back), and can be fixed in the adjusted orientation. As shown in Reference Figure 1, which shows the usage state, the angles of the first guide and second guide (the inclination angle when viewed from the side) are adjusted to match the lie angle of the golf club, and the plate-shaped portion is placed on the ground in that state. In this state, by matching the lie angle of the golf club with the inclination angle of the rod-shaped portion of the first guide and practicing a golf swing while being conscious of aligning the arc of the swing with the arc of the second guide, the ideal golf swing can be mastered. Furthermore, as shown in Reference Figure 2, which shows the usage state, the angles of the first guide and second guide can be set to different angles. In particular, by adjusting the angle of the second guide, the shape of the arc of the second guide as seen from the user's line of sight can be freely changed. Therefore, by adjusting the angle of the second guide to an angle appropriate for the swing practice menu, the desired training can be performed efficiently. Furthermore, the rod-shaped portion of the first guide is configured to be extendable and contractible, and can be adjusted to a desired length.In addition, the arc-shaped portion of the second guide can be disassembled into a central part and end parts, and it can also be used with one or both end parts removed, as shown in Reference Figures 3 and 4, which show the state of use. This allows the length of the arc of the second guide to be adjusted, and also makes it possible to set whether the arc is longer before or after hitting the ball.
