PRIORITY
-
This application is the Non-provisional application of provisional application No. 62/156,915 (Confirmation No. 5966), filed on May 5, 2015 for “Basketball Training Device, System and Method” by Dan Constantin. This Non-provisional application claims priority to and the benefit of that provisional application, the contents and subject of which are incorporated herein by reference in their entirety.
BACKGROUND
-
The present invention relates generally to a device, system and method for shooting a basketball at and through a basketball basket, and more specifically, to a device, system and method directed towards training a shooter to increase the accuracy of shooting a basketball. It is therefore an object of the invention to improve basketball shooting.
-
Basketball is a popular team sport worldwide, particularly in the U.S. While many skill sets are required to play the game, accurate basketball shooting—where players seek to score points for their respective teams (or individually, in the case of a “one-on-one” game)—is paramount. After all, points are scored and accumulated by making “baskets”—shooting a basketball such that it passes through a hoop attached to a backboard and suspended at a set height (typically, ten (10) feet) above the floor or ground of a basketball court.
-
As is generally known by basketball players of various ages and skill sets, the size of the basketball, the size of the hoop and backboard and the height of the rim of the hoop may vary. Basketballs—spherical inflated balls used in a game of basketball—typically range in size from very small promotional items only a few inches in diameter to extra-large balls nearly a foot in diameter used in training exercises to increase the skill of players. The standard size of a basketball in the National Basketball Association (NBA) in the U.S. is 9.5 to 9.85 inches (24.1 to 25.0 cm) in diameter, generally understood to be the “regulation” size of a basketball, and is used at the professional, collegiate, high school and upper elementary school level for boys and men. Basketball sizes for women and girls tend to be slightly smaller and youth sized basketballs even smaller.
-
The backboard, also an integral piece of basketball equipment, is a raised vertical board with the basket attached to it. The backboard is made of a flat, rigid piece of material, often Plexiglas or other non-breakable or shatter-able clear, glass-like material and is usually rectangular in shape, as used in NBA, collegiate, and international basketball games. Some backboards, such as those seen at playgrounds and outside facilities, may be oval or a fan-shape and comprised of a non-clear or opaque material, such as plastics, resins, composites or metal alloys.
-
The basketball hoop—with a net attached via specially adapted attachment hooks—is mounted to the basketball backboard in many settings via a flexible connection between the backboard and the connection supporting the hoop. The shock of a basket or a dunk is absorbed by the connecting part, so that the rim goes back to a horizontal position after the shot. Basketball hoops used in playgrounds, recreational settings and for personal use, however, often lack such a flexible connection and are rigidly attached to the backboard.
-
With regard to NBA, collegiate (NCAA), high school and upper elementary school levels, the top of the hoop is 10 feet above the ground or basketball court. The ten (10) foot height is considered “regulation” height; hoop heights less than ten (10) feet are generally directed towards youth players new to the game who are learning how to shoot. Many commercial basketball backboard/hoop sets used by individuals and regularly seen in the driveways and streets of homes have a means of raising and lowering the backboard/hoop portion to accommodate players of varying skill sets and ages.
-
Regulation backboards are 72 inches (183 cm) wide by 42 inches (110 cm) tall. All basketball rims (hoops) are 18 inches (46 cm) in diameter. An inner rectangle that is typically stenciled, painted or otherwise marked upon the backboard immediately above the hoop—to be used as a visual target for “bank” and/or “lay-up” shots—is 24 inches (61 cm) wide by 18 inches (46 cm) tall.
-
Consistent, accurate basketball shooting is a skill that requires extensive practice to achieve. Development of “muscle-memory” or “muscle-mind memory” (referred hereinafter simply as “muscle-memory”) is an important part of that process—with patience, proper coaching and hours of endless practice, a shooter develops over time a mental-physical connection of the “feel” for making baskets from various distances and conditions. Yet, while players may develop the ability to improve their shooting accuracy, the lack of a true “target” for which to aim, particularly longer perimeter or 3-point shots, creates difficulty for coaches, parents and more advanced players to help teach budding or less accurate shooters how to improve their shooting skills and accuracy. Indeed, becoming a consistent, accurate shooter requires immense effort and dedication of “practice, practice, practice,” wherein when a shooter makes a “perfect shot” (in the parlance of the game, a “swisher”), the positive feedback of making the basket is the reinforcing mental factor that builds the required muscle-memory needed for consistent, accurate shooting. As such, “trial and error” is essentially the approach to “learning” how to make baskets.
-
The present invention distinctly provides the missing substance that reduces the amount of time required in the lengthy “trial and error” approach to acquiring consistent, accurate shooting skills. The invention, in its various embodiments, provides the shooter with a mental-visual “target” for the shooter to focus upon that promotes faster “feel” recognition, thereby building and enforcing muscle-memory for consistent, accurate shooting for the shooter. An embodiment of the invention is comprised of the method for making consistent, accurate shots, when, once understood by the shooter, provides a mental context for target acquisition. A further embodiment of the invention comprises a first combination of devices that develop, promote and build consistent, accurate shooting by providing a visual aid for target acquisition in terms of centerline straightness and depth, as discussed in greater detail, below. A further embodiment of the invention comprises a second device that also develops, promotes and builds consistent, accurate shooting by providing a visual aid for target acquisition in terms of optimum shot angle recognition, as discussed in greater detail, below. As such, the invention may be understood to refer to any or all of the following embodiments, singly or in any combination thereof (said embodiments are illustrative and not meant to be exhaustive or limiting the nature or scope of the invention in any sense):
-
- 1. A method of shooting a basketball, sometimes referred to herein as the “shooting method,” that improves the accuracy of making the shot;
- 2. A first combination of devices or embodiments that develop, promote and build consistent, accurate shooting by providing a visual aid for target acquisition in terms of centerline straightness and depth;
- 3. A second combination of devices or embodiments that also develop, promote and build consistent, accurate shooting by providing a visual aid for target acquisition in terms of optimum shot angle recognition; and
- 4. A combination of the first and second embodiments or devices, or any portions thereof, for developing, promoting and buildings consistent, accurate shooting.
-
Importantly, the method embodiment of the invention is fundamentally and ultimately free and independent of the devices or physical embodiments of the invention, i.e., the shooting method does not require the use of the various device elements or embodiments. As such, it is possible for any individual to teach, learn, apply and use the shooting method without the aid of the various physical device elements or embodiments of the invention. The device elements or embodiments, however, greatly aid in teaching the shooting method, as those physical embodiments provide key visual aids (target acquisition) and instant mental feedback to the shooter, thereby enhancing muscle-memory development for consistent, accurate shooting.
-
Likewise, use of the device embodiments of the invention do not require that the shooter have knowledge of or understand the shooting method, although knowledge of the method is preferable for optimal use of the device embodiments. The devices, singly or in combination, will teach and reinforce consistent, accurate shooting irrespective of the shooter's understanding of any methodology. The devices, singly or in combination, will teach, reinforce and improve the shooting of a player of any skill level.
-
While a user need not necessarily have knowledge of or understand the shooting method in order to use and benefit from the device elements or embodiments to improve shooting accuracy, having such knowledge and understanding of the shooting method may prove to be of benefit to the user and facilitate in the training process, thereby improving shooting accuracy at a faster or more effective rate.
SUMMARY OF THE INVENTION
-
1. The Shooting Method
-
While the concept of “bull's eye shooting” is generally understood as reflecting strictly defined standards in sports of “aiming and shooting,” such as darts, archery and rifle shooting, the concept of such “bull's eye shooting” is not generally or commonly understood or applied in the game of basketball. It is noted that many references to bull's eye shooting are mainly loose in nature, such as, for example, “excellent shooting” as defined by “shooting percentage.” Nonetheless, as demonstrated by the present invention in its embodiments, bull's eye shooting—or shooting accurately and consistently based on target acquisition and development of muscle-memory—may nonetheless be found in and applied to basketball.
-
In general, the achievement of skill, control and accuracy in any athletic endeavor, and in particular, shooting a basketball, reflects and requires a natural human need for “exactness” in aiming and shooting that is expressed in relation to and in terms of the physical specifications of the “basketball hoop—shot interaction.” Most simply and specifically expressed, human skill, control and accuracy in aiming and shooting a basketball is maximized when aiming and shooting is characterized by the following three (3) “values” that define the shooting method embodiment:
-
- 1. Basketball hoop centerline straightness (hereinafter, referred to as the “centerline-straightness”);
- 2. The 43-45 degree basketball hoop entry angle (hereinafter, referred to as the “optimum arc-angle”); and
- 3. The 11 inch basketball hoop depth (hereinafter, referred to as the “optimum shot-depth”) (collectively, all three (3) values, the “shot values”).
-
The three (3) shot values, discussed in greater detail, below, most specifically and accurately, mathematically and spatially describe the flight, pathway and end point of the shooting method in relation to and in terms of the basketball hoop. While other variables—such as, for example, a towering defender attempting to block a shooter's shot —may require deviation from one or more of the three (3) shot values (in this example, a shooter will necessarily need to shoot over the extended arms or height of the defender, thereby increasing the shot angle as the ball enters the hoop plane), the three (3) shot values by and large represent optimal shooting parameters.
-
Other than a “slam dunk” or “dunk” shot, all basketball shots follow a parabolic path from the moment the basketball leaves the shooter's hands. The angle of the shot path relative to the ground, floor or basketball court (assumed to be dead flat with respect to gravity), changes constantly along the shot path. From the moment the ball leaves the shooter's hands until after it passes through the hoop (if a successful shot) and hits the floor of the basketball court, the angle of the shot arc is continually changing. Indeed, only at a single point in the shot trajectory—when the ball reaches its maximum height in the shot—the arc angle is at zero (0); at that instant, the ball is neither rising nor falling with respect to the floor and the basketball hoop plane, which run parallel with each other. After such instant, the ball begins to drop at an ever increasing rate and the angle of the arc increases relative to the hoop plane.
-
A basketball entering the hoop plane directly from above, i.e., perpendicular to the ground, floor or court, would have a 90-degree arc. Hereinafter, unless otherwise defined, the terms “shot arc,” “arc” and “arc-angle” or “arc angle” are meant to mean and be defined by the intersection of the center of the basketball as it passes through the plane of the basketball basket hoop. Unless the shooter is “dunking” the basketball, a 90-degree arc is impossible—the ball flight always takes the shape of a parabola. A basketball approaching the hoop directly from the side, i.e., parallel to the ground, floor or basketball court (and thus, also parallel to the hoop plane), has a 0-degree arc and entering the hoop plane at that angle is impossible.
-
Free throws, jump shots, set shots—all basketball shots other than “dunks,”—always enter the plane of the basketball hoop at an arc-angle that is generally between 32 degrees and 60 degrees. A shot arc-angle of 40-52 degrees is preferable and a shot arc-angle of about 43-45 degrees is optimal, i.e., the optimum arc-angle. As basketball shots enter the hoop plane at an angle, rather than from directly above as with a 90-degree arc (unless the ball is dunked or dropped from a standing position immediately above the hoop plane), the basketball hoop does not appear—from the perspective of the ball in its trajectory path—as a full circle. Rather, because the basketball enters the hoop plane at an angle, the hoop appears as an ellipse rather than a circle. The ellipse is the “apparent hoop size,” since a basketball entering the hoop plane at an angle does not have the benefit of the entire 18-inch diameter of the hoop.
-
The flatter the arc, the smaller the ellipse or apparent hoop size. A basketball entering the hoop plane at an arc-angle of 32 degrees, therefore, only “sees” or encounters an apparent hoop size that is just large enough for the ball to pass through the hoop plane. If the ball attempted to enter the hoop plane at an arc-angle any less than 32 degrees, the ball would simply not pass through the hoop and would bounce off the front or top of the rim, as the ball is simply too large to pass through the ellipse of the effective hoop plane. At an arc-angle of 32 degrees, the height of the ellipse of the apparent hoop size is 9.7 inches—the exact diameter of a men's basketball (as previously noted, NBA basketballs are generally 9.5 to 9.85 inches in diameter; for purposes of this disclosure, a basketball diameter size of 9.7 is used as the exemplary model size). As such, at an arc-angle of 32 degrees, the apparent hoop margin—the additional hoop space when the center of the basketball passes through the hoop plane—would be zero inches, allowing no room for shooter error. In order to make a basket, all basketball shots must have an arc-angle of 32 degrees or greater.
-
As the arc-angle of a shot is increased to 35, 45 and 55 degrees, the apparent hoop size increases, as does the apparent hoop margin. A basketball shot that enters the hoop plane with an arc of 90 degrees (for example, which may be accomplished by dunking the ball), has the largest apparent hoop size and apparent hoop margin. A dunk shot sees and has the benefit of the entire 18-inch hoop circle—the maximum apparent hoop size—and a 8.3 inch apparent hoop margin (18″ apparent hoop size minus 9.7″ diameter of men's basketball=8.3″ apparent hoop margin).
-
Other than dunk shots, shots with arc-angles greater than the optimal range of 43-45 degrees become increasingly more difficult to make. Shots with increasingly greater arc-angles—for example, shots with arc-angles of 70 or 80 degrees—must necessarily have higher trajectory paths in order for the ball to pass through the hoop plane. Short distance shots—such as those taken from “within the paint”—may, in certain instances, require higher arc-angles in order to avoid a towering defender. However, at greater distances from the basketball hoop—such as perimeter shots from 15-20 feet or 3-point shots, a high arc-angle shot requires an unusually high trajectory and greater flight time. This, in turn, decreases shooting accuracy, as the longer the ball is in air, minor errors made by the shooter when shooting the ball are amplified over the longer trajectory of the shot and the lengthier flight time. Thus, while a larger arc-angle affords the shooter a larger hoop circle and hoop margin by which to make the shot, such shots are more difficult to make—particularly as distance between the hoop and shooter is increased—as the lengthy, parabolic trajectory path of the shot amplifies minor inaccuracies made at the moment the shot is taken.
-
The three (3) shot values—centerline straightness, optimum arc-angle and optimum shot-depth—define the “sweet spot” intersection of maximum hoop size and hoop margin as balanced against shot trajectory, path and air time. The three (3) shot values comprising the shooting method are graphically depicted in FIGS. 1-2.
-
FIG. 1 is a perspective side view depicting a basketball entering the basketball hoop plane in accordance with the shooting method, i.e., integration of the three (3) shot values (only two (2) values are graphically depicted in this two-dimensional perspective: 1) optimum arc-angle and 2) optimum shot-depth). The center of the basketball is passing through the basketball hoop plane at a shot-depth of 11 inches from the front of the rim (optimum shot-depth) and the shot arc is 45 degrees (optimum arc-angle). In FIG. 1, the basketball is entering the hoop plane perpendicular (90 degrees) to the backboard, such as, for example, as would occur in a free throw shot from the foul line on a basketball court, which runs parallel to the backboard. A “free throw” and other similar basketball game terms as used herein, is generally understood by players of the game and the approach of the shot would be directly towards the center of the backboard and in a path that is directly perpendicular to the backboard.
-
FIG. 2 is a perspective top view depicting a basketball entering the basketball hoop plane in accordance with the shooting method, i.e., integration of the three (3) shot values (again, only two (2) values are graphically depicted in this two-dimensional perspective: 1) centerline-straightness and 2) optimum shot-depth). The center of the basketball is passing through the basketball hoop plane at a shot-depth of 11 inches from the front of the rim (optimum shot-depth) and the shot is centerline straight vis-à-vis the hoop diameter (centerline-straightness). Again, in FIG. 2, the basketball is entering the hoop plane perpendicular to the backboard, such as, for example, as would occur in a free throw shot from the foul line (see preceding paragraph).
-
The disclosed shooting method provides mental target acquisition, allowing the shooter to mentally and visually “see” the target. When the three (3) shot values are simultaneously achieved by the shooter, the resulting shot is a perfect “bulls-eye” shot.
-
2. Device Embodiments
-
The device embodiments of the present invention comprise various physical elements, features, assemblies and portions that help promote and reinforce shooting that results in achieving the three (3) shot values of centerline-straightness, optimum shot-depth and optimum arc-angle, thereby developing muscle-memory for consistent, accurate shooting. The various device aspects of embodiments of the invention may generally be referred to as follows (all of which comprise various additional features and elements as described further within):
-
- 1. A centerline/shot-depth assembly portion;
- 2. An arc-angle assembly portion; and
- 3. Combination of the centerline/shot-depth assembly portion and the arc-angle assemble portion.
-
Further comprising the device embodiments and/or portions of the invention is a bracket assembly portion for attaching said devices to a basketball backboard for use while shooting. While the bracket assembly portion is disclosed as an embodiment portion of the invention, it is to specifically understood that the centerline extension portion/embodiment, the shot-depth assembly portion/embodiment, singly or in combination, and the arc-angle assembly portion/embodiment, in combination with any of the forgoing, may be used in certain circumstances (e.g., suspended from a ceiling), without the bracket assembly. Nonetheless, various exemplary embodiments comprise or contemplate the use of a bracket assembly (whether as shown or otherwise) for detachable attachment to a backboard. While the devices may be used in various configurations, for optimum efficacy, it is suggested that they be used in combination and attached to a basketball backboard as further described herein.

DETAILED DESCRIPTION
-
A more detailed description of the invention now follows.
-
FIG. 3 depicts a perspective view 100 of a presentation or embodiment of the invention comprising a combination of various physical elements, features, portions and embodiments of the device aspects of the invention that promote and reinforce shooting for centerline-straightness, optimum shot-depth and optimum arc-angle, thereby developing target memory for consistent, accurate shooting—even after the targets are removed. FIG. 4 depicts a further perspective view 200 of the presentation of FIG. 3 and FIG. 5 depicts yet another perspective view 300 of the same presentation or embodiment of the invention of FIG. 3 (reference may be required to the additional attached drawings, FIGS. 6-9, for identification and referral of the feature, element or portion described).
-
Referring FIG. 3, a shot-depth assembly portion 30A is detachably attached and suspended from a centerline-straightness assembly portion 30B, thereby comprising, in combination, a centerline/shot-depth assembly portion 30. While the shot-depth assembly portion 30A and centerline-straightness assembly portion 30B comprise separate embodiments of the invention, in an embodiment, as disclosed herein, both embodiments are integrated into a combination centerline/shot-depth assembly portion embodiment 30.
-
In FIG. 3, the centerline/shot-depth assembly portion 30 is detachably attached to and suspended from a bracket assembly portion 40, wherein the bracket assembly portion 40 is detachably attached to a basketball backboard 10. The centerline-straightness assembly portion 30B is comprised of further elements and features, discussed in greater detail herein, including a centerline target extension element 34, which is aligned with the center of a basketball hoop, defined by the rim 20. Further attached to the centerline target extension element 34 is an arc-angle assembly portion 50. It is understood that the basketball backboard 10 and rim/hoop 20 are not features, elements or limitations of the invention, but comprise a standard, regulation basketball backboard and hoop to which the embodiments comprising the invention are intended for use.
-
The illustrated embodiments of FIGS. 3-5 teach consistent, accurate shooting by providing visual and mental aids or targets for the shooter to develop target and muscle-memory and shooting skills consistent with the three (3) shot values of centerline-straightness, optimum shot-depth and optimum arc-angle. In particular, the centerline target extension element 34 (which also provides a means of attachment to other assembly portion embodiments) of the centerline-straightness assembly portion 30B provides a visual centerline target for the value of basketball hoop centerline-straightness and may be brightly colored for easy centerline target acquisition (all elements, features and portions of the various embodiments may be similarly colored, as desired, for target acquisition or other reasons).
-
The shot-arc-angle assembly portion 50, and in particular, the at least one shot-arc targets 52 (a plurality in the depicted embodiment) provide a visual target or reference for the value of a 45-degree basketball hoop entry angle, i.e., optimum arc-angle. Lastly, the shot-depth assembly portion 30A, and in particular, the dome element 32 thereof, which is attached to and freely suspended from the centerline target extension element 34, provides a visual target or reference for the value of the 11-inch basketball hoop depth, i.e., optimum shot-depth. The embodiments of the invention depicted in FIGS. 3-5 comprise various physical elements, features, assemblies and portions that help promote and reinforce shooting directed towards the three (3) shot values of centerline-straightness, optimum shot-depth and optimum arc-angle, thereby developing target memory and muscle-memory for consistent, accurate shooting, even after the targets of the embodiments of the invention are removed.
-
In practice, a shooter relies upon the three visual references or targets of the embodiments depicted in FIGS. 3-5 (and as further detailed in FIGS. 6-9) to achieve consistent shooting that comports with the desired shot values. When shooting, the shooter visually engages the centerline target extension element 34 to align the shot with the center of the basketball hoop. That is, the centerline target extension element 34 is the visual representation of the centerline target and presents a strong visual target for the shooter to mentally focus upon. The shooter further visually engages the shot-arc targets 52 for visual and mental reference as to the 45-degree arc-angle at which the center of the ball should enter the plane of the hoop. Through trial and error, i.e., by taking shot after shot (practicing), the shooter will come to appreciate the feel or muscle-memory of shooting a basketball so that it enters the plane of the basket hoop at the optimum arc-angle of about 45 degrees. Lastly, by aiming and shooting the basketball so that it merely touches or grazes the center front dome element rim 32B on the downfall of the shot trajectory as it approaches the hoop plane, the shot is ensured of approaching the desired approximate 11 inch shot-depth value. Through trial and error, and depending on a shooter's style, height and other variables, the height of the dome element 32 may be manually adjusted (raised or lowered) above the rim hoop 20 as desired for personal tweaking. Some shooters may find a preference to aim the basketball so that it merely “nicks” the center front dome member rim 32B on the downfall of the shot trajectory as it approaches the hoop plane, and therefore a slightly raised dome element 32 will provide an optimum visual aid. Other shooters may prefer to aim the basketball so that it more directly makes more contact with the center front dome member rim 32B on the downfall of the shot trajectory as it approaches the hoop plane, and therefore a slightly lowered dome element 32 will provide an optimum visual aid. With minor tweaking, the shot-depth assembly portion 30A may be fixed at an optimum height for an individual shooter to achieve the shot value of optimum shot-depth.
-
Referring to FIGS. 3-5, the centerline target extension element 34 is detachably attached to the bracket assembly portion 40 via a centerline extension mounting element 49 (to detachably attach the centerline target extension element 34 to bracket assembly portion 40). By tightening and loosening a securing means 49A, such as, for example, a threaded bolt with an ergonomically shaped knob or handle for easy gripping by a hand (or any such other means commonly known in the art), the centerline target extension element 34 may be raised or lowered through a receiving mounting aperture 49B in the centerline extension mounting element 49, or removed entirely from the bracket assembly portion 40. This allows height adjustment of the dome element 32 above the rim 20 in accordance with an individual user's preference. In addition, the centerline target extension element 34 may be marked at set distances along its axis for easy readjustment for two (2) or more user or users' preferences (raised or lowered, depending on the user or between two (2) or more users. Such markings may further be numbered so as to represent a measuring stick, such as a standard yardstick, for maximum accuracy.
-
The inner diameter of the receiving mounting aperture 49B in the centerline extension mounting element 49 must be sufficiently sized for receipt of the centerline target extension element 34 without being too snug, tight or constricting. This allows easy adjustment (raising and lowering) of the centerline target extension element 34. The inner diameter of aperture 48B should be slightly larger than the outer diameter of the centerline target extension element 34. While the aperture 49 and the cross-section of the centerline target extension element 34 may be of any shape—so long as they can accommodate each other—a preferably embodiment is that they are circular in shape.
-
The arc-angle assembly portion 50 is also adjustable and may be raised, lowered or removed from the centerline target extension element 34. In the illustrated embodiments, the arc-angle assembly portion 50 comprises an attachment support element 59, which is further comprised of a center hub mounting aperture 59A and a tightening and loosening securing means 58B, such as, for example, a threaded bolt with an ergonomically shaped knob or handle for easy gripping by a hand (or any such other means commonly known in the art). By tightening and loosening the securing means 58B, arc-angle assembly portion 50 may be raised or lowered along the axis of the centerline target extension element 34, or completely removed therefrom. In addition, the inner diameter of the center hub mounting aperture 59A must be sufficiently sized for receipt of the centerline target extension element 34 without being too snug, tight or constricting. This allows easy adjustment (raising and lowering) of the arc-angle assembly portion 50 along the axis of the centerline target extension element 34. The inner diameter of center hub mounting aperture 59A should be slightly larger than the outer diameter of the centerline target extension element 34. While the center hub mounting aperture 59A and the cross-section of the centerline target extension element 34 may be of any shape—so long as they can accommodate each other—a preferably embodiment is that they are circular in shape.

The ability to raise and lower the shot-depth assembly portion 30A and the arc-angle assembly portion 50 is important for setting the optimal height of said potion embodiments above the hoop rim 20 that are best suited for the shooter as discussed above. As a starting reference, an embodiment of the invention comprises that the lower end of dome member 32, defined in the drawings as dome element rim 32B, be set at a height within the range of 10-12 inches above the hoop rim 20 plane, and a preferable starting height of 10.5 inches above the hoop rim 20 plane, and that the shot-arc target assembly portion 50 be set such that lower end of the shot-arc target sites 52 are within a range of 8-10 inches, and preferably 9 inches, above the top of the dome member 32. Such parameters, however, may be adjusted in accordance with a user's preferences that help achieve consistent, accurate shooting for that user.
-
FIG. 4A depicts an embodiment of the invention as illustrated in FIGS. 3-4, but without the arc-angle assembly portion 50. It is intended that the arc-angle assembly portion 50, detachably attached to the centerline target extension 34, may be removed in total from the invention, based on a user's preference.
-
Referring to more specific aspects of the various embodiments of the invention, as depicted in FIGS. 3-5, and as detailed in FIGS. 6-9, a centerline element 30B is disclosed, which is comprised of the centerline target extension element 34 (described above in relation to the shot-depth assembly portion 30A, the arc-angle assembly portion 50 and the bracket assembly portion 40) having a first terminus 34A and a second terminus 34B. In the depicted embodiments, the first terminus 34A is the lower end of the centerline target extension element 34, to which the shot-depth assembly portion 30A is attached and freely suspended, and the second terminus 34B is the upper end of the centerline target extension element 34. The second upper terminus 34B is detachably attached to the bracket assembly portion 40. In between said two ends 34A, 34B, the arc-angle assembly portion 50 is detachably attached.
-
The centerline target extension element 34 is the only embodiment/portion of the invention that connects to or is otherwise detachably attached to the other embodiments or portions of the invention depicted in the drawings, namely, the shot-depth assembly portion 30A, the arc-angle assembly portion 50 and the bracket assembly portion 40. Ideally, the centerline target extension element 34 should be aligned in a near perfect vertical orientation and perpendicular to the floor or basketball court. In an embodiment, the centerline target extension element 34 is cylindrical in shape and comprised of a sturdy, hollow tube (to avoid excess weight as compared with a solid, i.e., non-hollow, element) and may further include various apertures to allow for attachment to the bracket assembly portion 40, the arc-angle assembly portion 50 and the shot-depth assembly portion 30A.
-
The shot-depth assembly portion 30A, depicted in greater detail in FIG. 6, is comprised of the dome-shaped feature dome element 32, which is further comprised of and/or defined by a lower dome element rim 32B and a plurality of dome element support ribs/elements 32C. The upper end of the dome element 32 is comprised of an upper dome portion 36 and a dome aperture 36A therein through which a swivel member 32A (such as, for example, a swivel ball comprised of a durable plastic material in an embodiment) connects to the first end 34A of centerline target extension element 34, thereby allowing the dome element 32 to freely swivel. It is important that the shot-depth assembly portion 30A, and in particular, the dome element 32 thereof, be allowed to hang freely when detachably attached to and suspended from the first terminus, lower end 34A of the centerline target extension element 34 so that it does not materially hinder, alter or encumber an incoming basketball shot. Whether hit hard or gracefully grazed by a basketball, the swivel member 32A should be such that the shot-depth assembly portion 30A, and in particular, the dome element 32, readily moves upon impact and returns quickly to its suspended position, ready for the next shot. The swivel member 32A may be detachably attached to the first terminus, lower end 34A of the centerline target extension element 34 (for easy replacement or substitution of alternative models or embodiments of dome member 32) by any number of commonly known means in the art, including a plastic strap element, rope, flexible synthetics, chain (metallic or otherwise), etc. While one form of swivel feature is described, it is understood that a variety of swivel means may be utilized to accomplish the same result.
-
In the illustrated embodiments of FIGS. 3-5 and further detailed in FIG. 6, the circumference of the dome element rim 32B in the depicted embodiments is generally equal to that of the rim 20, and thus, would have a diameter of about 18 inches. However, various dome element 32 sizes may be used and individual shooters may find that a larger or smaller dome element 32 size is preferable. The dome element 32 is further comprised of dome element support ribs/elements 32C that provide support, yet present minimal visual blockage of the backboard and less distraction to a shooter. However, dome element 32 may be comprised without ribs, i.e., a solid piece with no openings, holes or apertures, or with any number or width of rib elements 32C, and further, the rim 32B thereof may be brightly colored for ready target acquisition. In other embodiments, the dome element 32 may comprise a swivel member or means 32A that does require an aperture 36A for suspension from the lower, first terminus end 34A of the centerline target extension 34. In such cases, any common swivel devices may be used, such as, but not limited to, hook and link, hook and chain, chain, and other swivel mounts, fixtures and hardware commonly available. The swivel member or means 32A may be comprised of any suitable material for its intended purpose.
-
Similarly, dome element 32 may be comprised of any suitable material for its intended purpose. Preferably, dome element 32 is comprised or manufactured of lightweight, yet durable material, such as, but not limited to, plastics, composites, certain metal alloys, etc. so as to provide minimal influence or impact on incoming shots, and may be produced via various extrusion processes. As the dome element 32 will be hit with basketballs during shooting, it is further important that the dome element 32 be composed of material(s) that may withstand continued impact over periods of time without breaking or cracking. Further, as basketball is often played outdoors, all features and elements of the physical embodiments of the invention should be comprised of materials able to withstand extreme weather conditions and exposure to UV light from the sun without deteriorating, breaking, fading, etc.

In the depicted embodiments, the bracket assembly portion 40 detachably attaches to both the backboard 10 and the centerline target extension element 34, to which other portions or embodiments of the invention are attached (detachably attached or otherwise). FIGS. 7-9 depict various perspective views of the bracket assembly portion 40 in greater detail. FIG. 7A provides even greater detail. In the illustrated embodiments, the bracket assembly portion 40 detachably attaches to the backboard 10, and, via the centerline target extension element 34, the bracket assembly portion 40 suspends the various other portions and embodiments of the invention above the rim 20. The bracket assembly portion 40 may be comprised of additional elements and features, and in the depicted embodiments of FIGS. 7-9, the following are provided as such additional, exemplary features: at least one (1) bracket backboard attachment top support 46, which hangs over the top of the backboard and extends down the front and the back of the backboard (i.e., in the depicted embodiment, “U” shaped); at least one (1) bracket backboard attachment brace 44 for detachable attachment to the bracket backboard attachment top support 46; at least one (1) attachment means 47 to detachably attach the bracket backboard attachment brace 44 to the bracket backboard attachment top support 46 and tightly secure to backboard 10 (said attachment means including, for example, a threaded bolt with an ergonomically shaped knob or handle for easy gripping by a hand, which may be used with corresponding and properly aligned threaded receptacle apertures in the bracket backboard attachment top support 46 and bracket backboard attachment brace 44 for receiving the threaded bolt for tightening and loosening, as desired by a user (or any such other means commonly known in the art)); at least one (1) bracket extender 42 element (to extend and align centerline target extension element 34 and secure same at a predetermined distance from the backboard 10); at least one (1) bracket backboard back support brace 48 for further support of the bracket assembly portion 40 against the backboard 10; at least one (1) centerline extension mounting element 49 for detachable attachment of the centerline target extension element 34 to the bracket assembly portion 40; a receiving mounting aperture 49B in the centerline extension mounting element 49 (through which the centerline target extension element 34 extends for detachable attachment and securing of the centerline target extension element 34 and for adjustment (raise/lower height) of shot-depth assembly portion 30A, and in particular, dome element 32, above hoop rim 20; at least one (1) securing means 49A to detachably attach and secure the centerline target extension element 34 to the bracket mounting element 49 (said attachment means including, for example, a threaded bolt with an ergonomically shaped knob or handle for easy gripping by a hand, which may be used with corresponding and properly aligned threaded receptacle apertures/holes in the centerline extension mounting element 49 for receiving the threaded bolt for tightening, loosening and adjusting the centerline target extension element 34 as desired by a user (or any such other securing means commonly known in the art or suitable for such intended purpose)); and, in the depicted embodiments, a bracket extension element 49C, which may be adjustable to properly align the centerline extension mounting element 49 over the center of the rim 20 plane circle and any required means for properly securing if adjustable, said securing means including, but not limited to, screws, nuts and bolts, or any other securing means commonly known to those skilled in the art. It should be understood that the bracket assembly portion described herein and depicted in the drawings is an exemplary, illustration of detachably attaching the centerline element 30B and the shot-depth assembly portion 30A of the centerline/shot-depth assembly portion 30 and the arc-angle assembly portion 50 to a backboard 10. While the illustrated bracket assembly portion 40 is utilized with depicted embodiments of the invention, it is to be understood that there may be many variations or other methods of detachably attaching the centerline element 30B and the shot-depth assembly portion 30A of the centerline/shot-depth assembly portion 30 and the arc-angle assembly portion to a backboard 10 and the bracket assembly portion 40, as depicted, is not necessarily a limiting feature of the invention. Indeed, the centerline element 30B may extend vertically and attach directly to a ceiling or other high enough structure and not attach to the backboard 10 at all, yet serve identical utility and functionality as if attached directly to the backboard 10—complete with the shot-depth assembly portion 30A and the arc-angle assembly portion 50 attached thereto.
-
The bracket assembly 40 may be detachably attached to the backboard 10 via combined single-piece bracket backboard attachment brace 44 and bracket backboard attachment top support 46, as demonstrated in FIGS. 4, 5 7-9 or by way of separate, two-piece combined bracket backboard attachment brace 44 and bracket backboard attachment top support 46, as demonstrated in FIG. 7A. The two-piece combination of FIG. 7A may be preferred to avoid digging or marking of the backboard 10 by the securing knob 47.
-
The bracket assembly portion 40 and the centerline target extension element 34, including all subparts, features and elements thereof, are comprised of strong, sturdy materials with minimal flexibility, such as metals, alloys, composites, plastics, resins and other like materials. By way of example, but without limitation, aluminum and various aluminum alloys, which generally are lightweight, durable and sturdy would be ideal, and may be produced by various and commonly known casting or extrusion processes. Such aluminum alloys may include, for example, aluminum alloys having metallic elements corresponding to the alloy series designations published by The Aluminum Association commencing with the numbers 3, 5, 6 and 7 (or proprietary equivalents or other certifying body equivalents).
-
In addition to the bracket assembly portion 40, other portions and elements of the embodiments of the invention described herein and depicted in the drawings may also be comprised of such as metals, alloys, composites, plastics, resins and other like materials. By way of example, but without limitation, aluminum and various aluminum alloys, which generally are lightweight, durable and sturdy would be ideal, and may be produced by casting or extrusion processes. Such aluminum alloys may include, for example, aluminum alloys having metallic elements corresponding to the alloy series designations published by The Aluminum Association commencing with the numbers 3, 5, 6 and 7 (or proprietary equivalents or other certifying body equivalents).
-
If comprised of aluminum alloy materials and created or manufactured via extrusion processes, such elements and features comprising the various portions and embodiments of the invention may be produced with a variety of finishes (both coatings and surface treatments). The types of coatings and treatments applied to subject aluminum extrusions include, but are not limited to, extrusions that are mill finished (i.e., without any coating or further finishing), brushed, buffed, polished, anodized (including bright dip anodized), liquid painted, or powder coated. After completing the extrusion process, such elements, features and portions of the various embodiments and assembly portions may further undergo operations to further complete the process, such as (but not limited to), cut-to-length, machined, drilled, punched, notched, bent, stretched, knurled, swedged, mitered, chamfered, threaded, and spun. This may be done prior to or after final finishing or painting.
-
Also, as these features of the invention will be struck by basketballs during shooting, it is further important that such elements and features be manufactured from or otherwise comprised of material(s) that may withstand continued impact over periods of time without breaking, cracking or other unwanted wear. Further, as basketball is often played outdoors, all features and elements of the physical embodiments of the invention should be comprised of materials able to withstand extreme weather conditions and exposure to UV light from the sun without deteriorating, breaking, fading, etc.
-
Importantly, it is to be expressly understood that, unless so stated, there are no dimensional limitations on the various features, elements or limitations of the various embodiments, portions or assemblies disclosed herein. For example, centerline target extension element 34 may be of length and thickness as required by the materials used for its construction and as suitable for its intended purpose. As such, if comprised of a metal alloy, such as a durable, sturdy and lightweight aluminum alloy, a diameter thickness of between 1-2 inches will likely be sufficient and preferable. Such a limitation, however, may be different if the element 34 is comprised of a different material. In addition, while there is specific limitation on the length of element 34, it would make little sense for the length to exceed the overall height of the backboard 10. As such, a preferable maximum length would be 42 inches—the dimensional height of a regulation backboard.

In the various embodiments of the invention as depicted in the drawings, the arc-angle assembly portion 50 is comprised of the following features or elements: an attachment support element 59 and a center hub 58 that further comprise a center hub mounting aperture 59A to securely detachably attach the arc-angle assembly portion 50 to the centerline target extension element 34 and to allow adjustment (raise/lower height) of the arc-angle assembly portion 50 along the axis of the centerline target extension element 34; a securing means 59B to detachably attach and rightly secure the arc-angle assembly portion 50 to the centerline target extension element 34 (said attachment means including, for example, a threaded bolt with an ergonomically shaped knob or handle for easy gripping by a hand, which may be used with a corresponding and properly aligned threaded receptacle aperture in the center hub mounting aperture for receiving the threaded bolt for tightening and loosening, as desired by a user (or any such other means commonly known in the art)); at least one (1) shot-arc target site radial support element(s) 56 (a plurality of said elements is illustrated in the depicted embodiment as radially extending from center hub 58 and attached to the shot-arc target support member 54); a shot-arc target site support member 54 (in the depicted embodiment, shown as a semi-circle shaped feature that is radially extended from and equal distant at all points from the centerline target extension element 34); and at least one (1) shot-arc target site(s) 52 (a plurality of said shot-arc target sites are shown in the depicted embodiment and are positioned at a forty-five degree (45°) angle with respect to the basketball rim 20 plane, in accordance with the method described above).
-
In the various embodiments of the arc-angle assembly portion 50 of the invention depicted in the drawings, a plurality of shot-arc target site radial support elements 56 and shot-arc target sites 52 are demonstrated. Specifically, in the disclosed embodiments the arc-angle assembly portion 50 comprises five (5) shot-arc target sites 52. Two shot-arc target sites 52 extend from the attachment support element 59, which runs parallel to the backboard 10. As such, the two shot-arc target sites 52 extending therefrom are also parallel to the backboard 10. The remaining three (3) shot-arc target sites 52 connect to and extend from three (3) radial support elements 56; the center or middle shot-arc target site 52 extends from a radial support element 56 that is perpendicular to the attachment support element 59 and the backboard 10; as such, the center shot-arc target site 52 is also perpendicular to attachment support element 59 and the backboard 10 and is oriented at a ninety (90) degree angle to both. The two (2) shot-arc target sites 52 on both sides of the center shot-arc target site 52 (i.e., each is between center shot-arc target site 52 and the two shot-arc target sites 52 extending from the attachment support element 59) or oriented at forty-five (45) degree angles with respect to attachment support element 59 and the backboard 10 (and thus, the radial support elements 56 to which they attach are also oriented at forty-five (45) degree angles with respect to attachment support element 59 and the backboard 10).
-
While the arc-angle assembly portion 50 may comprise any number of shot-arc target sites 52, five (5) is a preferable. Five (5) shot-arc target sites 52 provides adequate visual coverage for a user—from baseline, to straight forward and in between—to acquire target recognition of the optimum arc-angle.
-
Referring to the illustrations, the center hub mounting aperture 59A allows attachment of the arc-angle assembly portion 50 to the centerline target extension element 34. The centerline target extension element 34 extends through said mounting aperture and the securing means 59B and complimentary/associated threaded hole or aperture (not shown) is used to securely tighten the arc-angle assembly portion 50 to the centerline target extension element 34. Of course, other commonly known means may be used to detachably attach, secure and adjust the arc-angle assembly portion 50 to the centerline target extension element 34.
-
The arc-angle assembly portion 50, including all subparts, features and elements thereof, are ideally comprised of strong and moderately inflexible materials, such as metals, alloys, plastics, composites, fiberglass, rubbers, and other like materials that can withstand impact, yet provide sufficient flexibility and give to soften an errant basketball shot. As these features of the invention will be struck by basketballs during shooting, it is further important that such elements and features be composed of material(s) that may withstand continued impact over periods of time without breaking, cracking or other unwanted wear. Further, as basketball is often played outdoors, all features and elements of the physical embodiments of the invention should be comprised of materials able to withstand extreme weather conditions and exposure to UV light from the sun without deteriorating, breaking, fading, etc.
-
As with other features, elements and limitations of the various embodiments, portions or assemblies of the invention, it is to be expressly understood that, unless so stated, there are no dimensional limitations on the various features, elements or limitations that comprise the arc-angle assembly portion 50. Preferably, however, the radius of the shot-arc target site support member 54 (in the depicted embodiment, shown as a semi-circle shaped feature that is radially extended from and equal distant at all points from the centerline target extension element 34) is nine (9) inches, with the center hub 58 of the assembly 50 being positioned directly over the center point of the hoop 20 plane. As such, the lower base of the assembly 50, being defined by the outer semi-circle perimeter of the shot-arc target site support member 54 and the attachment support element 59, is the approximate size of half of the hoop 20 plane and positioned approximately directly over the front half of the hoop 20 plane. A preferable length of the of shot-arc target sites 52 is that they not exceed or be greater than the top of the backboard 10. Generally, an approximate length of eighteen (18) inches for the shot-arc target sites 52 would suffice and it may be preferable that they be brightly colored for ready target acquisition. The thickness of the shot-arc target sites 52 depends on the material used for composition. Generally, it may be preferred that the shot-arc target sites 52 be cylindrical or rod-like in shape with a thickness or diameter of approximately one (1) inch to avoid over obtrusiveness. As noted, the shot-arc target sites 52 must be comprised of a durable, flexible material that can withstand weeks, months and years of basketball abuse.
-
Importantly, use of the devices of the embodiments of the invention teach, develop and reinforce target memory and muscle-memory for consistent, accurate shooting by a shooter. With practice with the embodiments, and, preferably, with knowledge of the shooting method, a shooter's shooting accuracy improves and becomes more consistent—even after the devices of the physical embodiments of the invention are removed, such as, for example, when the practicing shooter plays in a basketball game. With knowledge of the shooting method, and by practicing with the physical embodiments of the invention, an individual may quickly become a stellar, bulls-eye basketball shooter.
