ABSTRACT:
TECHNICAL FIELD
The present invention relates to the field of basketball return devices; particularly, to devices that are easily mounted and dismounted from a basketball goal assembly and act to return a basketball thrown towards a basketball goal apparatus to a player shooting the ball.
BACKGROUND OF THE INVENTION
The development of proficiency in any sport requires many hours of practice and many repetitions of basic skills. The sport of basketball poses several particular hardships to any aspiring player willing to spend the many hours necessary to improve his or her game. First, the development of shooting skills requires a nearly countless number of repetitions of shooting acts performed from varying distances and angles towards the goal apparatus, more commonly called the “net.” Second, the ball is often deflected away from the shooter as it rebounds off the backboard, rim, other parts of the goal, or misses the goal apparatus entirely, called an “air ball.” Even if the ball passes cleanly through the net, backspin or topspin on the ball can cause the ball to be irregularly reflected when it strikes the playing surface beneath the net. Lastly, while many of these problems are minimized by having another person retrieve shot balls, it can be difficult for a player to recruit another person to practice with, and sharing practice time with another person will decrease the amount of practice that a single player could gain on his or her own in an equivalent time period.
What has long been needed is a simple and inexpensive mechanical device, that can easily be located in an operational position for practice and then removed entirely or moved to a unobtrusive position for actual play, that reflects a basketball shot, regardless of whether the shot is errant or scoring, and which tends to reflect the basketball back towards the shooter.
Many attempts have been made to satisfy these needs. One general class of devices might be considered to utilize a net capture system. Examples of these devices include U.S. Pat. No. 6,074,313 to Pearson, and U.S. Pat. Nos. 5,540,428 and 6,224,503 to Joseph. In addition to being extremely bulky, these net capture device have several other drawbacks and do not have the versatility of the present invention. Net capture systems either tend to return the ball to a fixed position, as with the Joseph '428 device, or to return the ball in no particular place or direction, as with the Pearson '313 device. Further, the Pearson '313 device will not return balls that fall straight down through the net, and the Joseph '428 and '503 devices partially block and obscure the basketball goal from certain angles. Similar such devices are U.S. Pat. No. 6,267,696 to Mabe, and U.S. Pat. No. 6,056,652 to Lees, et al., which substantially also limit the possible shooting positions which can be taken relative to the net.
Another class could be denominated the hoop mounted director, such as that seen in U.S. Pat. No. 5,779,569 to Townsend, et al., U.S. Pat. No. 5,443,258 to Kinsella, or U.S. Pat. No. 5,409,211 to Adamek. These devices act to direct balls falling through the net into a scoop shaped trough that returns the ball in whichever direction the trough is aimed, which is not, of course, necessarily in the direction of the shooter. Also, these hoop mounted director devices are completely ineffectual for any ball not passing through the net. Another type is the ground mounted reflecting net, as seen in U.S. Pat. No. 6,209,877 to Warnick, which would require surface damaging fixation points to the floor or playing surface to be adapted to basketball use, as otherwise the reflector net will tend to tip over and slide away when it is struck by a ball. The relatively great distance, compared to a goal apparatus mounted device, at which a ground mounted reflector would lie relative to the basketball goal means that a very large reflector net would have to be employed to reliably receive even a portion of the missed shots. Additionally, balls that impact the net at an angle will generally be reflected away from the location in which the shot originated.
There are also flat plate reflecting systems designed to be mounted on the rim or on the goal supports. In the former category is U.S. Pat. No. 5,265,870 to Merino. The non-adjustable plate of Merino '870 will tend to reflect the ball away from the shooter, as the angle of reflection will be reciprocal to the angle of incidence, and thereby substantially defeat the utility of such a system. The rigid plate of Merino '870, being mounted to the rim support, will require an awkward reaching to a level of 10 feet, the height of a standard basketball rim and well above the reaching height of nearly any player, in order to put the device on, or take it off, the rim support structure. In the goal apparatus mounted class is, for example, U.S. Pat. No. 5,273,276 to Warren, which provides for a rigid reflecting plate that will allow the ball to bounce against the plate and be reflected to a pre-set position. The Warren '276 device requires that the player adjust the apparatus in advance to determine the point to which the ball will be returned. A player cannot move quickly between different shooting positions, since a re-positioning of the apparatus is required for each change in shooting position. The number of positions to which a ball can even be theoretically returned is limited by the number of azimuthal and elevation locking pin stops provided, unless the device is further fine tuned through its pivot points. A player would have to estimate, or learn through trial and error, which pin stops and pivot point fine tuning adjustments should be selected to accomplish a given direction of return. The rigid reflection plate is unlikely to reflect the ball any great distance, especially should the ball fall gently through the net. In a converse situation, when the ball strikes the reflecting plate with some force, especially if it strikes the plate near the edge, the rigid reflecting plate will directly transfer very large impact forces to the central pivot mounting. This will tend to cause a high level of wear, and possible breakage, by concentrating the force of a sudden impact at a single point.
Many of the shortcomings of the prior art result from the use in these goal assembly mounted devices of fixed attachments to the basketball goal apparatus. Such fixed points tend to restrict the direction in which the ball can be returned without cumbersome adjustments of the mountings, dissipate the kinetic energy which is needed for ball return, and concentrate undesirable loads at vulnerable points of the apparatus. The present invention, in contrast, uses flexible mounting attachments at several key points to the goal assembly, which allow the return apparatus a slight degree of rotational movement when struck by an incoming ball. This motion tends to re-direct the ball back to the shooter in a reciprocal direction to that of the incoming trajectory, or in other words, towards the shooter. This effect takes place as an incident of the design, and requires no adjustment of the apparatus to change the direction of reflection. As a result, the player is free to quickly vary his or her shot distance and angle, and yet still have the ball returned, without any adjustment of the return apparatus. Such flexible mountings also tend to conserve the momentum of the basketball during reflection for returning the ball and minimize the wear on the return apparatus. The device may be mounted within the reach of nearly any player, and can be easily removed or adjusted out of the way of the playing court from the goal apparatus if desired.
What continues to be needed but is missing from the field of basketball return devices is a lightweight device that reliably returns the basketball in the direction of the shooter, is easy to set-up, adjust, and is constructed to endure the abuse associated with repeated impacts. Further, the device must be easy to fabricate to ensure the apparatus is economical. While some
