  • Patent number: 6062992
    Abstract: An improved ball mark repair tool which can be used to relieve compaction of the earth surrounding the ball mark in a correct manner and then gently force the earth upwardly and inwardly about the ball mark so as to raise the turf and properly fill the indentation. More particularly, in one form of the invention, a downward pressure exerted upon the handle of the device will urge spaced apart earth engaging repair prongs to penetrate the earth in an area surrounding the ball mark and then to automatically move the prongs inwardly relative to one another to loosen the soil and urge it inwardly and upwardly so as to correctly restore the surface of the green to a substantially planar condition.

  • Patent number: 5746265
    Abstract: A lanyard connects a pair of head covers for golf clubs together by a connector section of predetermined thickness with a hole therein for receiving the lanyard. The lanyard includes an elongated line element having opposed ends with a pair of protruding members near each of these opposed ends. Each pair of protruding members has an outer most and and inner most member which are spaced apart a distance about equal to the predetermined thickness of the connector section. One end of the line element has a tab section that extends from an adjacent outer most protruding member nearby the one end of the line element which facilitates pulling the adjacent outer most protruding member through one hole in one cover. The other end of the line element has another tab section that extends from an adjacent outer most protruding member nearby this other end of the line element which facilitates pulling the adjacent outer most protruding member through this other hole in the other cover.

  • Patent number: 4725063
    Abstract: Disclosed is a device used to practice putting including a putting station and a remote target station. The putting station comprises a mat on which two parallel rows of posts are provided which straddle parallel strips that serve as guides for the putting head. The number of posts in each row may be the same or different. If there is an unequal number of posts, an entry way and an exit way is provided through which the club head may be moved by the golfer when swinging at the ball. The target station includes a body member having two parallel ramps, separated by a vertical wall, which lead to a collector section. One ramp serves as an entry ramp and target. The other ramp serves as an exit ramp to allow the ball to move under the force of gravity from the collector section. The collector section includes a lip which acts as a stop to prevent the ball from rolling beyond the target station if it is moving at the desired speed, but will allow the ball to roll over it if it is moving at an excessive speed.
