  • Publication number: 20250027757
    Abstract: The disclosed non-lethal bursting projectile diversionary device is designed to be used as an offensive device by teachers and other users to deter, disorient, and potentially disarm a shooter or an aggressor. The device is non-lethal and contains a non-toxic composition adapted to plume into the air upon impact of the device with an aggressor or object. The device includes a housing that has a frangible outer cylindrical wall. An inner cavity extends from a proximal end of the housing to a distal end of the housing. The inner cavity is filled with a novel composition which includes dense fly ash, light fly ash, glass beads, and glitter. The device is launched toward an aggressor using an air propelled launcher, and the composition is expelled through a bursting of its spiral seams thereby creating a disorientating plume around the device and the aggressor which disorients and deters the aggressor.

  • Patent number: 12110073
    Abstract: A portable utility wagon trailer is provided having a support frame connected to a single axle operatively connected to two opposing wheels. The support frame includes at least four low friction blocks mounted thereon. The portable utility wagon trailer includes a deck having a pair of opposing side rails disposed beneath the deck. Two of the low friction blocks operatively engages one side rail in a slidable arrangement, and the other two of the low friction blocks operatively engage the opposing side rail in a slidable arrangement. A spring biased locking pin removably engages an aperture defined by at least one side rail, for locking the deck in a fixed position for transport. The deck is configured to be collapsed by a user and then stood upright for storage.
