Ball Travel-Modifying Device

摘要

A ball travel-modifying device comprising a sail and a strikeable object modifies a travel distance and a rate of travel of a struck or thrown object and returns the strikeable object to an initial rest position after each hit or throw. Devices built in accordance with the invention are particularly suited for use with strikeable objects which are various kinds of balls. A separation distance between the strikeable object and the sail is adjustable. A separation distance between the strikeable object and a surface upon which a player stands may also be adjustable. In some embodiments, the strikeable object may be replaced with a strikeable object having a different size or weight. The shape of the sail is triangular, quadrilateral, or other shapes and may be symmetric or asymmetric. The sail may alternatively be formed with a flat or curved surface and straight or curved edges. One or more apertures may be formed in the sail to modify a speed or a direction of a moving strikeable object. Some embodiments have at least one adjustable aperture to permit adaptation to various strikeable objects having a variety of sizes and weights or to cause a strikeable object to move in a preferred direction or with a preferred rate of travel.

主权项

1. A device attached to an anchor for modifying the travel of a strikeable object, comprising:
a sail having a first end, a second end, a first side, and a second side; a suspension line, wherein said suspension line is removably attached to the anchor and said first end of said sail is connected to said suspension line; a spreader, wherein said spreader maintains a preferred distance between said first side of said sail and said second side of said sail; and a strikeable object coupled to said second end of said sail.
