Abstract: A golf swing training device can be easily worn by a user, without requiring any special connection mechanism or clothing item, to provide adjustably positionable sights that assist users in improving their golf swing. One goal of the training device is to keep the golfer's vision focused on the ball while taking the swing and minimize head movement, especially during the backswing. When the correct focus is established, the swing will follow, therefore enhancing muscle memory to improve the user's swing consistency. A pair of focusing rings may be flexibly connected to a mounting system. The focusing rings can be positioned to help the golfer focus on the ball while taking their swing, especially while putting. The mounting system can secure the focusing rings in the desired position during use, while being comfortable to wear.

The control signal transmits the GPS coordinates of the sports disc locator system to a personal data device.

Abstract: Adjacent blocks are biased in directions of mutual contact using elastic cords, the adjacent blocks being changed so that surfaces having mutually different positional relationships are brought into contact with each other in resistance to the biasing force of the elastic cords, whereby the blocks can be transformed between a state of being folded so that the external shape becomes compact, and a state of being extended so as to take on the shape of an object to be expressed. Furthermore, at least two of the blocks among the plurality of blocks have a state in which two surfaces of each of the blocks simultaneously contact each other, the block-type transformable toy thereby being configured so that turning about the elastic cords is limited.
