  • Patent number: 5236197
    Abstract: A weight adjustable, shock and vibration absorbing tennis racket comprising a generally oval shaped headframe with a handle attached thereto, and a striking surface therein formed by stringing the headframe with a string in the conventional manner. A pair of elongate recesses are formed along the inner periphery of the headframe at opposed positions thereon and aligned with the center of percussion of the headframe. A pair of projections are formed on respective opposed longitudinal sides of each recess. A vibration absorbing rib can be releasably secured to each recess, with the ends thereof snap fitting into respective projections of a corresponding recess. String holes for cross strings passing through a recess are arranged in two staggered rows with a pair of adjacent cross strings diverging to a respective pair of adjacent string holes disposed on opposing rows.

  • Patent number: 5228699
    Abstract: There is provided a game board for playing a board game, and methods for playing the same. The board is divided into eight rows and eight columns which define sixty-four squares. These squares alternate in color to define thirty-two playing spaces. These spaces are assigned a value such that the sum of the valued spaces contained in the middle four rows of the board is greater than the sum of the valued spaces contained in the first two and last two rows of the board. Points are awarded during play for movement of playing pieces upon the valued spaces of the board, and for jumping the opponent's playing pieces. Points are tallied for each player to determine a winner.

  • Patent number: 5165687
    Abstract: A damping assembly for a sports racket is disclosed as being applied between a grommet or grommet strip associated with the racket and the racket frame to which the grommet or grommet strip is attached. The damping assembly includes a layer surrounding the outer surface of the frame preferably to at least 25% of the circumference. The layer is applied to the frame by adhesive material which allows the damping material to restrict frame vibration by shear-damping which resists shear deformation across the thickness and not along the length. The damping layer may be formed from a composite plate consisting of a number of plies of different grain orientation to optimize the shear-damping characteristics.

  • Patent number: 5137280
    Abstract: An entertainment/educational game is provided which teaches players thereof about geography. The game includes a playing surface having a geographical area divided into subregions illustrated thereon, the geographical area and subregions having geographically significant shapes. A plurality of elongated, flexible members (e.g., colored strings) having fixed, equal lengths are provided as playing pieces, one for each player (or team). An object of the game is to accumulate points while attaching ones playing piece to the playing surface within subregions to achieve some predefined goal (e.g., extending one's playing piece across the geographical area or forming a loop with one's playing piece), while attaching one's playing piece to at least a minimum number of subregions. Players draw cards which include indicia corresponding to one of the subregions. Players attach a portion of their playing piece to the playing surface within a subregion if they can locate the subregion within a preset time period.

  • Patent number: 5120061
    Abstract: For improvement in aerodynamic characteristics of a golf club head at swing, the transverse cross-section of the hosel is defined by a winged profile which includes at least one of a convex heel and concave toe sections. The sole face is defined by a convex sphere of a specified radius of curvature. The crown and sole faces are defined with vertical symmetry by respective convex spheres of similar radii of curvature. Current transition around the club head at swing is well prevented for higher head speed. Bias buoyancy at swing are minimized for a stabilized swing line.

  • Patent number: 5120063
    Abstract: A practice golf putting cup is disclosed that eliminates the inclined ramps and ball trapping leaves found in the prior art by taking advantage of in-floor air ducts found in many homes. The invention consists of a cover for the air duct passage and has an opening in it blow which is attached a ball receiving cup that extends into the air duct. A ball retrieval basket with an attached flag pole is placed in the collecting cup and is used to retrieve putted balls. Aligning air holes in the receiving cup and retrieval basket permit the passage of air into or out of the air duct. By rotating the retrieval basket in the receiving cup, the amount of alignment of the air holes can be changed so as to control the amount of air flow.

  • Patent number: 5118112
    Abstract: A system for analyzing the balance of a golfer during a golf swing and to determine weight shifts from one foot to the other and between the heel and toe of each foot during a golf swing. Basically the system comprises two foot pads capable of measuring weight on each pad and on the front and rear portions of each pad, a display for displaying weight information in digital and/or graphical form, a sound sensor for sensing the impact of a golf club against a golf ball and a microprocessor system for receiving information from the pads and generating the display. In use, a golfer positions the foot pads where his feet would be in his normal golf stance, arranges the display in front of the pads a safe distance away, positions the cable between footpads and display out of the way and places a normal golf ball on a tee or on the ground the appropriate distance from the footpads. The unit is turned on and parameters are set, the golfer stands on the footpads and then takes his normal swing at the golf ball.
