Title: Table tennis paddle

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to structures known as bats, rackets or paddles (hereinafter, “paddles”) for use in ball games. It specifically relates to paddles for use in table tennis or ping pong games. 
     2. History of the Prior Art 
     in most racquet sports, particularly table tennis and ping pong (hereinafter collectively referred to as “table tennis”, the paddle consists of a flat paddle surface (“blade”) of varying shape attached to, and in the same plane of a handle. As a result of this single plane configuration, any effort to strike a ball so it moves in any direction other than in a perpendicular plane to the players body requires the player to twist or bend his or her wrist in proportion to the angle of ball movement which is desired. 
     In addition, the players movements are constrained by the need to either rotate the paddle up to 180 degrees or more around the player&#39;s body, or to change the hand holding the paddle to allow a backhand shot to be made. 
     To explain, as opposed to the forehand side of the body, the backhand side is considered to be the one opposite the hand holding the paddle when the player is at rest. Similarly, the backhand side of the paddle is (as opposed to the forehand) that side which faces in the opposite direction of the palm of the hand which holds the paddle. To change play from forehand to backhand, the paddle must be fully rotated around the player&#39;s body from its forehand to its backhand side. Not only is this required rotation somewhat awkward to achieve, it also causes the player to lose much of the time available to address the ball and positioning the paddle for play. 
     Further, the traditional table tennis paddle consists of a substantially cylindrical handle immovably attached to the paddle blade. Except for the possible presence on the handle of cushioning means (such as compressible foam), the handle does not conform to the players hand. As a result, it can only be gripped by allowing the hand to encompass the handle, leaving the paddle in a substantially perpendicular position with respect to the player&#39;s wrist. This particular grip is referred to as the shake hand grip, which is the most used grip in conventional table tennis. 
     As a result, the most comfortable paddle position is not the one best suited for play, thus encouraging fatigue of the player&#39;s wrist and hand, in having to tilt the wrist forward to lower the blade to more closely become an extension of the arm. 
     What is needed, therefore, is a paddle for racquet sports, and particularly for table tennis, which allows the player to comfortably make forehand, backhand, and angled strokes with minimal adjustment of the paddle position. 
     SUMMARY OF THE INVENTION 
     In essence, the paddles of this invention consist of two principal structural components which are either formed separately and joined, or molded as a single piece. These components are the blade and handle, which can be made of structural foam, wood or plastic. In the embodiment described, the two structural components are made of wood, and the attachment of the handle to the blade must include each of the following points:
         (1) The center line plane of the handle and the plane of the blade are two separate but intersecting planes not to exceed 45 degrees.   (2) The handle contained within its plane is rotated outward and downward from the terminal end attachment line of the handle to the blade, thus allowing the paddle surface to be an extension of the arm rather than perpendicular to the wrist, as is normal with conventional paddles.   (3) The plane of attachment of the handle to the blade lies between the lines of intersection of the planes containing the two parallel sides of the handle with the blade.   (4) The playing surface of the blade extends only forward from the terminal end attachment line of the handle with the blade. This feature allows the same surface area on both sides of the blade for striking the ball.   (5) In addition, the handles are structured to conform to the player&#39;s hand and a comfortable wrist position, and further configured to provide for a more secure grip than provided by conventional paddles. The handle has two curvatures along the inner gripping surface separated by an extension of said surface.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
       FIG. 1  depicts one embodiment of the invention paddle in perspective view. In this embodiment, the blade  1  and the handle  2  are separate components. The handle  2  is substantially a curved pistol grip configuration, where the terminal end  9  at the upper extension of the handle  2  is attached by attachment means to the forehand face  5  of the blade  1  along the edge thereof. The forward attachment line  8  is parallel with the terminal end  9  of the side of the handle  2 . A left handed paddle would be a mirror image of  FIG. 1 , the right handed paddle; which allows for, as shown in  FIG. 3  a right hand and left hand paddle handle to be combined as one, on a single blade, with the centerline plane of the handles being the same. The center line plane containing the handle  2  and the forehand face  5  of blade  1  are two separate, but intersecting planes not to exceed 45 degrees, with both planes being perpendicular to the floor, best shown in  FIG. 2 . The handle  2  contained within its plane is rotated outward and downward from the attachment section  4  to the blade  1 . The handle  2  is an open handle with only one attachment  4  on the side at the upper end of attachment leg  3 . Regardless of the amount of the rise of the handle  2  from the blade  1 , based upon the chosen angle of the attachment section  4 , the two sides  6  and  7  and the centerline plane of the handle  2  remain parallel with the line of attachment  8 , and are perpendicular to the horizontal centerline plane of the wrist and forearm when held in a level position relative to the floor; thus, the blade  5  is in a vertical alignment position relative to the floor, but angled inward for optimum play with either side of the paddle. Note: the alignments, as described, allow for an offset handle from the blade, but do not allow for any rotation of the handle relative to the blade; thus, the blade is a perfect extension of the wrist and forearm, as if the fingers were extended forward. 
     The plane of attachment  4  of the handle  2  to the face of the blade  5  lies between the lines of intersection of the planes containing the two sides  6  and  7  of the handle. 
     The forehand surface  5  of the blade  1  extends only forward from the terminal end attachment line  8 . This feature allows the same surface area on both sides of the blade for striking the ball. The blade may be any number of configurations, but is substantially configured within a 6 inch width by 6 inch height. 
       FIG. 2  shows the preferred gripping alignment. The gripping of the handle is with the thumb positioned along the upper surface  10  of the handle  2  above the upper end attachment line  4  of the blade  5  to the handle  2 , to allow for greater rotational capability of the paddle. 
       FIGS. 1 and 2  show the most preferred handle configuration. The most preferred handle configuration for a very secure grip, while allowing the player to have a semi-relaxed hand grip during play, is having two curvatures  12  &amp;  13  along the gripping surface to conform, respectively, to the index finger, and possibly, the middle finger of the player&#39;s hand, with the thumb resting along the top surface  10  of the handle instead of being wrapped around the handle, while the second curvature  13  accommodates the remaining fingers of the player&#39;s hand. The extension  11  between two of the fingers stabilizes the handle and prevents it from sliding out of position while being held onto lightly. 
     The angle of attachment of the handle to the blade allows the player to strike the ball with either side of the blade without rotation of his or her grip on the handle regardless of whether the ball approaches the player on the forehand or backhand side, although it is expected that the backhand surface of the blade will be used predominately in play, It should be noted, that the angle of attachment allows for the most comfortable and effective play as it allows the player to use its backhand surface on the forehand side of the body and, conversely, the forehand surface on the backhand side of the body. 
     The advantage of using the backhand surface of the blade predominately to strike the ball in play is that the response time needed to set up the play by having to rotate the paddle from the backhand to the forehand side, with a conventional paddle, is eliminated. For that reason, the angled handle will enhance backhand play, but will also allow forehand strokes to be utilized to best advantage in strokes requiring the ball to be stroked more forcefully downward onto the table from any position either to the left or right of center. 
     It will be appreciated by those skilled in the art that modifications can be made to the embodiment of the invention disclosed herein without departing from the spirit or concept of the invention. 
     Description of New Handle 
     The alternative to the double handle on a single blade, to accommodate both a right hand player as well as a left hand player, is to have a single handle with an adjustable finger separation extension which can be removed and reattached to the other side of the handle to convert from a right hand racket to a left hand racket. 
     The following alternative modification  FIG. 4  describes a single handle which is designed for both right hand and left hand play. The upper surface of the handle  14  and the lower surface of the handle  15  are symmetrical curves relative to the horizontal centerline plane  19  of the handle  2  and blade  5 . The upper surface  14  and the lower surface  15  of the handle extend out from the attachment line  9  of the handle  2  to the blade  5 , and are curved so as to comfortably fit the player&#39;s hand. Within the horizontal centerline plane of the handle  2  with the blade  5 , the handle is lifted up from the forward attachment line  9  of the handle  2  with the blade  5  to an angle not to exceed 45 degrees. The finger separation extension  18  for the underside of the handle  15  has a screw in attachment piece  20  which is removable, and can be attached to the other side of the handle, thus converting the racket from a right hand racket to a left hand racket. The finger separation extension  18  between two of the fingers stabilizes the handle in the player&#39;s hand, with the first finger and possibly the second finger resting forward of the extension, and the remaining fingers resting to the rear of the extension. This configuration allows the player to have a stable and semi-relaxed grip during play.
