Definitions

  • This invention relates to a golf practice mat for the practice and refinement of the golf swing, and more particularly to a golf and divot practice mat with a mark retaining layer having one or more images of a golf ball printed or otherwise illustrated thereon, and method for using same.
  • Prior devices have attempted to provide such practice tools in variety of different manners.
  • a significant limitation of all prior devices however, is that such devices are often cumbersome, expensive, unreliable, and not particularly convenient for improving golf skills.
  • Prior art devices that recorded the contact area of the golf club to the golf ball do not give the same type of information about the swing as one can have with a record of the contact area of the golf club to the ground.
  • U.S. Patent 2,660,436 to Grossman discloses a device wherein a laminated layer is secured to the face of the golf club. When a mark is left upon this device, it is not readily observed, but instead one must look closely at the face of the club. In addition, only one swing can be taken per device, or else one no longer knows which swing had caused which contact mark. Thus, a change to the equipment must be made between each swing. In addition, the device requires that an actual golf ball be struck. This is a limitation on where and how the device can be used. U.S.
  • Patent 5,609,530 to Butler discloses an invention to record the "toe up” or “toe down” attitude of a golf club as it is swung through past the ground.
  • This device once again carries the limitation that the recording is done on the club, requiring modification of the club to be swung. Also, only one swing can be made before a disruption to the practice round must be made to replace the device on the club. Also, although this device does give some information about the way in which the club and the ground have come into contact with each other, the information is limited in that no "dynamic" record is made. What is called for is a device that allows for the dynamic recording of the contact area of the golf swing to the ground. Ideally, the device would allow for multiple swings, and make multiple records, before any modification be needed to the device. In addition, the device should be able to record such detailed information in a way that allows for easy storage of the information at relatively low cost.
  • the present invention provides a golf or divot practice mat that is convenient to use, reliable, inexpensive to manufacture, and may be used either inside or outside.
  • the divot mat of the present invention is easy to use, and provides instant and reliable feedback about a user's golf swing by leaving a mark around and near a simulated golf ball imprinted on a paper or other impressionable surface. This visible mark gives immediate information to the user as to the quality and characteristic of the swing, and guides the user to improve the golf swing.
  • various types of golf practice devices are known in the prior art, none are directed to a mat having a surface with simulated printed golf balls which are marked by the swing of a golf club by the user, thereby indicating instantly and recording permanently characteristics of the swing.
  • the present invention provides for the practice of a golf swing and the recording of the contact area of the club to the apparatus. This contact area is recorded as a retained mark.
  • the mark is similar to the divot one would see on the ground after swinging the club on turf.
  • Review of the mark, which represents a divot allows for analysis of the swing which made the mark. A trained eye may make such an analysis, or a guide may be used to help the layman with such an analysis.
  • the present invention allows the contact area to be recorded on an easily removable and replaceable layer such as a piece of no carbon required paper.
  • the records are lightweight and relatively inexpensive.
  • the golfer may practice his swing many times before needing to remove and replace the paper, while still having separate records of individual swings.
  • the golfer gains the experience oflooking at a golfball during swing practice.
  • the golfer may also learn to focus on the ball and keep his or her head down while practicing the swing. This is an important aspect of a golf swing.
  • the ease in which the record of the contact areas can be removed and replaced from the apparatus allows for a continuous practice session without long interruptions.
  • the present invention provides a golf or divot practice mat which is highly efficient at training a user to be a better golfer.
  • the golf or divot practice mat of the present invention may used successfully by beginning golfers, intermediate level golfers, or expert golfers at many locations, either inside or outside, without the need or any other equipment or accessories other than a golf club. Accordingly, it is an object of this invention to provide a divot or golf practice mat with an impressionable surface having one or more imprinted simulated golf balls thereon.
  • the impressionable surface is preferably composed of a no carbon required (NCR) type paper, but may alternatively be composed of or contain a wax, a carbon paper, or the like.
  • NCR no carbon required
  • the invention allows for the recording of the contact area between a golf club and the recording surface, which simulates the ground.
  • the invention also allows for multiple swings to be recorded without the golfer having to do more than to slightly relocate his or her stance.
  • the recording sheet When the recording sheet has been used up, the recording sheet is easily removed and replaced. The sheet then becomes a permanent record of the contacts between the golf club and the apparatus (which simulates the golf course). Additional objects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.
  • the present invention is a golf or divot practice mat, comprising a base element and a mark retaining layer removeably secured or mounted to a base element.
  • the mark retaining layer may be a no carbon required paper, carbon paper, or wax containing surface, and has one or more simulated golf balls imprinted thereon.
  • the mark retaining layer may be secured to the base element by dowels, adhesives, hook and loop fastening material, or other fastening mechanism.
  • a mark is left on the mark retaining layer which instantly records the contact area of the golf club with the practice mat. Analysis of the mark allows for characterization of a golf swing' s position and angle of contact with the simulated golfball.
  • the practice mat may be conveniently used anywhere, indoors or outdoors.
  • a method for the practice of a golf swing including attaching a mark retaining layer to a base element, and swinging a golf club using the mark retaining surface as a simulated golf course surface.
  • a mark retaining layer for the recording of the contact area of a golf club swing with the mark retaining layer.
