Projection On Face Of Swingable Implement Head Provides Reduced Striking Area Patents (Class 473/236)
  • Patent number: 11547920
    Abstract: A training device can easily be affixed or mounted to the hitting face of a golf club. The training device may provide auditory, tactile, and directional feedback for the user during practice so that he/she may learn how to strike the ball consistently on the sweet spot. A training device may include several raised surfaces of varying shapes rising from the base surrounding an aperture centered over the sweet spot of the golf club and larger than the surface area contacted by the ball. Use of the training device may reduce the user's variance from the “sweet spot” due to a strike not only along the longitudinal axis but also along the vertical axis. The user avoids impingement with the raised surfaces of the training device by striking the ball within a pre-set tolerance as well as within the boundaries of the aperture.

  • Patent number: 10561922
    Abstract: Devices and methods are generally provided for indicating the location of a most recent strike on a face of a golf club. One exemplary embodiment of an impact indication device can include a patch that can be attached to the face of a golf club and can display the impact location of a most recent strike without displaying impact locations of previous strikes. The impact locations of previous strikes can be removed from the patch without the user having to do anything more than take another swing. In some embodiments, the device includes a yield-stress material that assist in displaying impact a most recent impact location without displaying previous impact locations. Other features that can allow patches to work in this fashion, as well as methods related to the same, are also provided. Further, disclosures pertaining to a mobile impact recorder are also provided.

    Abstract: This golf rules conforming dual-purpose putter invention is created to provide a golf putting club that can be either used to play the game of golf with the flat front face surface or be used for putting practice to train the eyes and muscles of the golfer. Precise putting practice develops the neurological sequencing of optimal skeleto-muscular effectiveness and is affected by using the radiused, ovoid back surface of the putter, to consistently strike the ball in a manner causing the ball to roll perfectly on the chosen path to and into the hole upon execution of the perfect putting stroke. This invention is for a golf putting club that provides immediate visual feedback of any positive, symmetrical, or negative, asymmetrical, contact between the planar centers of the putter and the golf ball. Imprecise contact at the putter center line, instead at a point toward the toe or the heel of the putter, and the impact point of the golf ball will cause the ball to roll in an erratic, off-axis direction.

  • Publication number: 20040147332
    Abstract: Several features are combined to provide a balanced putter, which assists a player in perfecting a putt stroke during practice and repeating it with the same club during play. The clubhead is substantially symmetric around the shaft and has tapered top and bottom surfaces such that the angle of the shaft relative to the sole of the putter is no more than 80 degrees. The shaft is attached at the center of the clubhead, and the clubhead and shaft are arranged so that the center of gravity of the clubhead strikes the center of the golf ball. The clubhead has a playing surface on one face that is parabolic and can be flat in the extreme. The clubhead has a practice surface on the other face that is curved, preferably elliptical, to assist the golfer in learning the proper stroke. The putter conforms to the Rules of Golf so that the player does not have to change clubs between practice and play. The club may be used for a right- or left-handed stroke.

  • Publication number: 20040137997
    Abstract: A laser or other focused beam is mounted in a device with the appearance from above of a golf ball which device can either rest on the ground in contact with a putterface or be attached to a putterhead or other clubhead such that the focused beam is at a 90 degree angle to the putterface. After the device user is satisfied that the club is properly aimed or aligned at a target, the laser beam is activated via a wired foot, or finger, or wireless switch such that the actual aim can be compared on a visible or blind screen behind the target with the intended target. The device can be used with any putter for putter training, putter club fitting, and putter aim testing and selection.

  • Patent number: 6729966
    Abstract: A pair of error amplification deflectors, releasably attached to the face of a golf club with hook and loop patches, are spaced to provide a central zone on the face of the club for directing a golf ball along a normal path upon squarely striking the ball, but are shaped for redirecting the path of the ball upon striking the ball to provide a signal indicative of an off-center putting stroke or golf swing. The hook and loop patches permit adjustment of the width of the center zone for different levels of practice difficulty, and provide further indication of an off-center stroke by absorbing energy to decelerate the speed of the redirected ball.
