  • Patent number: 9908023
    Abstract: A retractable ball return system having a rebounding surface that is retractable on a roll back into a reel assembly housing, which housing is mountable above a garage door opening or in an open space such as a gymnasium. The rebounding apparatus includes an integrated cable support structure, which is securable at its lower corners to attachment members mounted to the garage door frame. The door frame attachments have a plurality of different connection points which allow the rebounding surface to be secured at different degrees of angle, from angling forward to angling back, or centered in the middle for a perpendicular setting. Once connected, the support cable is retracted, either manually or mechanically, to pull the cable taught, to allow for a strong support structure. The rebounding surface is also then retracted until it has a desired tension level to allow the rebounding surface to be used with different balls as well as to adjust the different performance levels with the same ball.
