20080220948 | HOPPING BALL - A hopping play ball has one or more water reservoirs in fluid communication with one or more squirt nozzles. The squirt nozzles are activated by a user. | 09-11-2008 |
20090291806 | Trampoline with dual spring elements - A trampoline provides higher performance and greater shock absorption capability by utilizing pairs of springs to connect the rebounding mat to the supporting frame. The springs in each pair are coupled to a common junction on the periphery of the rebounding mat, being disposed vertically with respect to each other. The upper spring in each pair is directly connected to the rebounding mat and the trampoline frame to initially to tension the mat in the equilibrium position. The lower spring in each pair is coupled to the frame and then to rebounding mat via a linkage arm such that it comes substantially under tension only as the corresponding upper spring is stretched. Depending on the level of impact force on the trampoline mat both springs extend, such that their combined stored energy propels the user upward on the return bounce. However, as each spring pair engages in stages the shock of the users initially landing is gradually absorbed. | 11-26-2009 |

20130210590 | PLYOMETRIC REBOUNDER OR THE LIKE - A trampoline-type device comprises an encompassing frame supported by plural legs and a mat suspended on the frame. The frame is supported by no less than three legs. Support members attachable to the frame convert the device into a plyometric rebounder. | 08-15-2013 |
20130316876 | REBOUNDING APPARATUS WITH TENSIONED ELASTIC CORDS - A trampoline with a frame has a rebounding mat that is tensioned to the frame with a plurality of flexible and cordlike linear elastic members. Preferably each cordlike elastic member is connected to the frame and the rebounding mat at one of two alternative positions to alter the tension. The alternative positions permit a tensioning process that extends the lifetime of elastic cords having a fabric sheath. This independent tension of each elastic member is via connector member that grips the rebounding mat but also grasps opposing the ends of the elastic members as well as central portion thereof so that two segment of the cord between each end and the central portion are preferably wrapped around the trampoline frame. | 11-28-2013 |
20140287880 | HINGE OR THE LIKE FOR FOLDING REBOUNDER - A portable exercise system has a foldable perimeter frame comprising at least two elongated frame members that are joined by hinges. The hinges are joined to ends of the frame members, which ends are generally tubular. Each hinge has a cap-like body having an interior surface that defines a cavity configured to nestingly receive one of the ends of the frame members. A deformable plug is located within the central cavity of the one of the ends. A tightening mechanism is operated to expand the plug radially and thereby cause the end to expand radially such the generally tubular outer surface of the end frictionally engages the interior surface of the a cap-like body. | 09-25-2014 |
