초록 ▼

Reusable, mechanically powered Paint Ball Grenade utilizing 0.68 or smaller diameter paint balls. Accepting and storing said paint balls between its upper and lower sections and behind a fingerguard. The device is designed to be grasped in such a way as to engage one or more safety interlocks during the removal of the safety pin. Once thrown downrange the actuator will function upon impact allowing the grenade halves to collapse with the force of the primary spring, crushing the paint balls against cutters and causing the paint to be hydromechanically dispersed about the exterior of the device. The device may be reloaded by expanding the two halves, thus compressing the primary spring, reinserting the safety pin, and reloading new paint balls.

A paint ball grenade comprising; a base member comprising a generally semi-spherical hollow shell having a lining extending across the open end thereof; a top member comprising a generally semi-spherical hollow shell having a planar member extending across the open end thereof, said planar member being located opposite to and in facing relationship with the lining, and a hollow tubular cap member defined by a wall centrally secured to and extending upwardly and outwardly from the top member shell, said cap having a pair of apertures located opposite each other in the wall thereof; a post extending upwardly from the base member shell, through the hollow interiors of the base member shell and top member shell and into the tubular cap member, said post having a bore extending transversely there through the upper end thereof, said post being fixed relative to the base member shell and the top member and cap being slidably moveable along the post between a first position in which the liner and planar member are spaced apart by a gap sufficient to receive there between one or more paint balls and the apertures in the cap are aligned with the bore in the post, and a second position wherein said liner and planar member substantially abut for squeezing paint from any paint ball positioned therebetween; a spring connected between the post and top member for biasing the latter to the second position; a depending guard member secured about the top member and extending toward the base member a distance sufficient to cover the gap when the top member is in the first position to guard against a user inserting a finger between the liner and planar members and to help retain any paint ball positioned in the gap within the grenade, said guard member having one or more paint dispersal ports to permit expulsion of paint from the interior of the grenade when the top member moves from the first to the second positions, and also having a door for insertion of paint balls into the gap when the top member is in the first position; a safety pin for insertion through the apertures in the wall of the cap and bore of the post when the top member is in the first position for locking the top in that position against movement to the second position and; means interacting between the top member and post for temporarily holding the top member in the first position when the pin is removed and for releasing the top member for movement to the second position under the influence of the spring upon the application of an impact force to the grenade; whereby one or more paint balls may be inserted into the grenade through the door into the gap when the top is held in the first position by the pin, the pin may be removed and the grenade thrown, and upon impact the top member will slide along the post to close the gap, squeezing the paint balls to rupture them and release the paint therefrom for ejection through the ports.
