Abstract: A game apparatus having a board, pieces, pegs and cubes. The board has a grid of spaces and several columns of holes. A margin separates the spaces from the edge of the board. One column of holes occupies the grid of spaces. The other columns occupy the margin. The pieces have holes and are designed for movement on the spaces. One of the pegs is moved between the holes in the spaces and the holes in the pieces. The other pegs are moved between the holes in the margin. The players take turns making plays. Each play ends with the move of a peg. The players take turns being the offense. In appropriate situations, the defensive player rolls a pair of cubes. If one or more symbols on the faces of the cubes are positive, the defense moves a peg from a hole in a space or a piece to another piece or another hole in a space. The first player unable to move a peg at the end of their turn loses the game.

Abstract: The champion perfect passer is an instructional device used to teach the skill of the forearm bump pass for the sport of volleyball.The passer is used by placing the fixed sleeves on the users biceps, and reaching the hands forward to grasp the moveable ball with thumbs together on top of the ball and rolling them over to a position where they contact the rod at its front with the tips of the thumbs. Fingers on both hands are clasped under the rod and pull up against the rod. This causes the arms to assume the proper passing position, and will not allow for the elbows to bend which is the most difficult bad habit to break in volleyball. All normal volleyball bump passing drills are completed with the passer in place and the student is taught proper form and body position.

Abstract: A field sport providing an outer boundary defining the playing area and consisting of a wall, fixed or portable, and an inner boundary defining an inner playing field in predetermined space relation from the outer boundary and in which the field the players must remain during play, the distance between the outer and inner boundaries being sufficient to prevent the possibility of contact between the wall and the players. A player passes a playing object (e.g. ball, puck, etc.) by projecting it against the wall to rebound back onto the playing field while the player remains in the field. Goals at either end of the playing area are provided. Goal keepers must remain between the inner and outer boundaries at either end of the playing area.

Abstract: A rotatable fishing arrow rest comprising a threaded support member (with or without lock nut) adapted to thread into an arrow rest hole provided in the arrow window of an archery bow wherein the support member pivotally retains a roller having a pair of rubber O-rings of two difference diameters (larger diameter O-ring mounted on the outer and the smaller O-ring mounted on the inner side of the roller relative to the archery bow) in the window area of the archery bow such that the arrow shaft makes rolling contact with each rubber O-ring as the arrow is launched. The rotatable arrow rest can further be equipped with a fabric cushion that attaches to the archery bow adjacent to the rubber O-rings such that the arrow shaft touches the fabric cushion as the arrow is launched. Such a rotatable arrow rest is particularly useful in absorbing the oscillations and lateral forces created in a fishing arrow shaft by the archery bow, while simultaneously reducing frictional losses.
