Patent Application
20160136498
This application claims priority to U.S. provisional patent application Ser. No. 62/081,368, filed 18 Nov. 2015, the complete disclosure of which is incorporated herein by reference.
The invention relates to an adjustable sports backboard, in particular a tennis backboard.
A variety of sports utilize rebound walls (“backboards”) to hone sport-specific skills and techniques. Tennis players use backboards to groove strokes, soccer players use them to develop kicking, ball control and defensive skills. Lacrosse players practice shooting technique and ball catching. No matter what the sport, athletes also develop cardio stamina, footwork and positioning skills while practicing on backboards.
An example of a suitable backboard is shown in my Published U.S. Patent Application Ser. No. 20090139157, published on 4 Jun. 2009, the complete disclosure of which is incorporated herein by reference.
Essential skills in all such sports involve both projecting a ball (hitting, throwing or kicking) and receiving and controlling balls from different distances, angles of trajectory and varied speeds. Backboard practice is one of the most widely incorporated practice methods in a variety of sports, worldwide.
Regardless of what material a backboard is made of, there are two basic styles. A Vertically Mounted Backboard (“Vertical”) that is erected at an approximate 90 degree angle to the playing surface and a Back-sloped Backboard, (“Back-sloped”) which is erected at an angle sloping away from the player at angles typically between 15 and 30 degrees. Both vertical and back-sloped backboards provide essential rebound characteristics required for efficient, all-around skill development.
Unlike most other sports typically practiced on a backboard, tennis requires that a ball be returned to the opponent's side of the net either before it bounces (a volley) or after one bounce and before a second bounce, a groundstroke. When a player is hitting ground strokes on an actual tennis court, he would receive his opponents shot after one bounce, approximately thirty six feet from the net. A player does receive/hit balls while closer to the net but most shots are hit from the baseline area. No matter how hard a tennis ball is hit against any type of vertical backboard, the ball will usually rebound and take its first bounce at a spot that is about half as deep as a typical return in an actual tennis match. This makes ground stroke practice on a vertical backboard less than ideal because it requires a player to stand much closer to the backboard to hit the ball on one bounce than the player would stand on an actual tennis court in relation to the net. The short, flat ball trajectory off a vertical backboard is particularly troublesome for beginner players because they lack the basic racket and positioning skills to react to the quicker ball rebound and likewise are forced to learn to hit groundstrokes at a position that is too close to the net.
On the other hand, a vertical backboard is superior for volley drills where the inherent, flatter, shorter rebound characteristics duplicates the actual flight of a ball that is ideally volleyed, (hit before it strikes the ground) or via a half volley, (played on a short hop). Moreover, side-to-side practice drills, that simulate close-to-net play and develop hand-eye coordination, footwork, proper racket and body positioning, muscle-memory and cardio endurance are best accomplished on a vertical backboard. Similarly, close-order soccer, basketball and lacrosse practice is best performed on a vertical backboard for the same reasons.
Practice on a back-sloped backboard, sloped away from the player between 5 and 30 degrees or more, provides a deeper, more lofted return that is ideal for realistic ground stroke practice. Additionally, the slower rebound speed allows a player, especially beginners to concentrate on stroke technique without having to cope with the much-faster and shorter rebound of a vertical backboard. These same characteristics are helpful in other sports training where ball trajectories vary as in soccer and lacrosse.
Prior to the subject invention, one had to choose between a vertical backboard or a back-sloped backboard. Given the pros and cons of each type of backboard, one always had to make a sacrifice in choosing one over another.
The fact that backboards are used to practice a variety of different skills, some suited to a vertical backboard and others to a back-sloped backboard, made choosing very difficult for players, facility owners and tennis instructors.
In order to provide a backboard that allowed all-around practice of all types of shots for beginner to expert players, one would need both a vertical and a back-sloped backboard. In most cases either the actual cost of the backboards or the cost of building the additional court space required for two types of backboards was prohibitive.
The subject invention provides for an adjustable backboard that allows a player to use the product in a vertical or back-sloped configuration.
Objectives of the invention can be provided by an adjustable backboard comprising:
Objectives of the invention are also obtained by a method of practicing tennis comprising the steps of:
adjusting an angle of the adjustable backboard; and
hitting tennis balls at the backboard so that the tennis balls rebound off of the backboard
The invention will be explained with reference to the attached non-limiting Figs.
A player may practice volley drills on a vertical backboard 2 as shown in
Backboards for tennis practice are now well known in the art. Any desired backboard can be modified by using an adjustable mount as described herein. The backboard should be sized for practicing tennis shots. An example of a suitable size for practicing tennis shots is a minimum of 12 feet of width×8 feet of height for an intermediate to advanced player. Backboards designed for use by beginners or by multiple players at once, should be made considerably wider with a minimum of 16 feet of width per player. The wider and higher the backboard the better regardless of skill level.
The position of the backboard 2 can be locked into a preferred angle by management with simple padlocks 12 on the scissor hinge 4 or by mechanical means 12.
It is to be understood that the foregoing illustrative embodiments have been provided merely for the purpose of explanation and are in no way to be construed as limiting of the invention. Words used herein are words of description and illustration, rather than words of limitation. In addition, the advantages and objectives described herein may not be realized by each and every embodiment practicing the present invention. Further, although the invention has been described herein with reference to particular structure, s and/or embodiments, the invention is not intended to be limited to the particulars disclosed herein. Rather, the invention extends to all functionally equivalent structures, methods and uses, such as are within the scope of the appended claims. Those skilled in the art, having the benefit of the teachings of this specification, may affect numerous modifications thereto and changes may be made without departing from the scope and spirit of the invention.
