SUMMARY OF INVENTION

The pickleball dink shot practice board is a training device. The pickleball dink shot practice board is configured for use with pickleball. The pickleball dink shot practice board is a portable backboard that is used to practice pickleball shots, both independently or with a partner. The dink shot is a shot that occurs when a ball is hit with a racquet (paddle) such that the ball is returned to a competitor with a backspin. The pickleball dink shot practice board comprises a backboard structure and a plurality of stanchion structures. The plurality of stanchion structures elevate the backboard structure above the ground. The backboard structure forms a backboard that deflects a pickleball back to the user of the pickleball dink shot practice board. Alternatively, the backboard structure acts as a divider if two players are practicing together.

It shall be noted that this concept may be used to practice other types of shots made with Pickleball.

It shall be noted that the ball can be returned with backspin, no spin, slice, topspin, at different angles, at different distances, forehand, or backhand side.

• • Dinks—Short shots that arc over the net and fall in the kitchen/non-volley zone (close to the net).
  • Drop shots—a shot that barely clears the board and is designed to land in the kitchen (non-volley zone).
  • Drop shot volleys—a volley shot done to take speed off the ball and return it short near the net.
  • Drives—a forehand or backhand shot hit straight and low (to your opponent or against the board).
  • Lobs—a high shot designed to go over your opponent's head.
  • Overhead slams—hitting a smash or overhead spike to put the ball away.
  • Punch shots—quick, short volley shots with little back swing and short follow through.

A plurality of cords are attached under tension (commonly referred to as “strung”) to the head such that plurality of cords forms the striking surface that transfers momentum from the individual using the racquet to the object. Alternately, the racquet can be a solid surface that transfers momentum from the individual using the racquet to the object. A racquet formed with a solid surface is often called a paddle.
  • Rectangle: As used in this disclosure, a rectangle is an enclosed four sided geometric structure. Each angle formed by the rectangle is a right angle. A non-Euclidean rectangle is a rectangle that is formed on a non-Euclidean plane.
  • Rectangular Block: As used in this disclosure, a rectangular block refers to a three-dimensional prism structure comprising six rectangular surfaces (commonly called faces) formed at right angles. Within this disclosure, a rectangular block may further comprise rounded edges and corners.
  • Rigid Structure: As used in this disclosure, a rigid structure is a solid structure formed from an inelastic material that resists changes in shape. A rigid structure will permanently deform as it fails under a force. See bimodal flexible structure.
  • Rotation: As used in this disclosure, rotation refers to the cyclic movement of an object around a fixed point or fixed axis. The verb of rotation is to rotate.
  • Slewing Bearing: As used in this disclosure, a slewing bearing is a bearing that is used to rotate an object around a vertically oriented axis of rotation. Slewing bearings are typically load bearing structures.
  • Stanchion: As used in this disclosure, a stanchion refers to a vertically oriented prism-shaped pole, post, or support.
  • Superior: As used in this disclosure, the term superior refers to a directional reference that is parallel to and in the opposite direction of the force of gravity when an object is positioned or used normally.
  • Supporting Surface: As used in this disclosure, a supporting surface is a horizontal surface upon which an object is placed and to which the load of the object is transferred. This disclosure assumes that an object placed on the supporting surface is in an orientation that is appropriate for the normal or anticipated use of the object.
  • Telescopic: As used in this disclosure, telescopic is an adjective that describes a composite prism structure made of hollow prism-shaped sections that fit or slide into each other such that the center axis of the composite prism structure can be made longer or shorter by adjusting the relative positions of the hollow prism-shaped sections.
  • Tool: As used in this disclosure, a tool is a device, an apparatus, or an instrument that is used to carry out an activity, operation, or procedure. A tool generally comprises a working element and a handle. The handle of a tool that forms a sub-component of a larger structure is referred to as a mount.
  • Vertical: As used in this disclosure, vertical refers to a direction that is either: 1) perpendicular to the horizontal direction; 2) parallel to the local force of gravity; or, 3) when referring to an individual object the direction from the designated top of the individual object to the designated bottom of the individual object. In cases where the appropriate definition or definitions are not obvious, the second option should be used in interpreting the specification. Unless specifically noted in this disclosure, the vertical direction is always perpendicular to the horizontal direction.
  • Working Element: As used in this disclosure, the working element of a tool is the physical element on the tool that performs the actual activity, operation, or procedure the tool is designed to perform. For example, the cutting edge of a blade is the working element of a knife.

With respect to the above description, it is to be realized that the optimum dimensional relationship for the various components of the invention described above and in FIGS. 1 through 12 include variations in size, materials, shape, form, function, and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the invention.

It shall be noted that those skilled in the art will H readily recognize numerous adaptations and modifications which can be made to the various embodiments of the present invention which will result in an improved invention, yet all of which will fall within the spirit and scope of the present invention as defined in the following claims. Accordingly, the invention is to be limited only by the scope of the following claims and their equivalents.
