Ball rebounding system

摘要

A ball rebounding device has high tension netting that is efficiently assembled, pulled taught and held in place within a frame using a tension rod system and a manufacturing process that uses levers between the frame and tension rods within the frame. The invention can be used in producing new ball rebounder and in retrofitting existing rebounder frames. The frame provides a perimeter support and an interior space. Tension rods are run through the cells of the netting and positioned in the interior space. A lever system is connected between the tension rods and the frame to pull the tension rods toward the corresponding sides of the frame, thereby drawing the net taught within the frame. Once the netting is pulled taught, fasteners hold the tension rods in place next to the sides of the frame. The frame can be rigid or may have flexibility and act like a spring.

主权项

1. A ball rebounding system, comprising:
a frame comprising a perimeter support and an interior space within said perimeter support; a tension rod having a first position spaced apart from said perimeter support and located in said interior space and a second position proximate to said perimeter support; a net comprising a plurality of cells, wherein said net extends between said perimeter support within said interior space of said frame, and wherein a row of said cells are directly laced onto said tension rod without any intermediate spring elements and without any cell-position limitations or cell-size limitations according to any position or size requirements of connection points on said frame; a lever system operatively connected to said tension rod and to said frame, wherein said lever pulls said tension rod from said first position to said second position, wherein said net is in a substantially slackened state when said tension rod is in said first position and wherein said net is in a taut state when said tension rod is in said second position; and a plurality of fasteners connecting said tension rod to said frame when said tension rod is in said second position.
