Abstract
A water penetrating blowgun dart is provided. The blowgun dart has a funnel removably attached to a tail end of the dart shaft so that upon contact with a water surface, the funnel moves from an engaged configuration to a disengaged configuration. The tail end may provide a slot for snugly receiving an eye, wherein the tail end and the eye have cooperating grooves so that when in the engaged configuration, the eye and tail end are secured with a filament that slightly protrudes from the flush outer surface of the shaft and eye. The protruding filament frictionally engages the funnel in the engaged configuration so that the funnel remains engaged with the shaft prior to hitting the water's surface.
Claims6
A blowgun dart, comprising:
- a shaft extending from a tip to a tail end, wherein the shaft is adapted to travel tip-first in a straight line through a fluid;
- a funnel moveable from an engaged configuration attached to the tail end to a disengaged configuration when the funnel contacts a surface of said fluid,
- wherein the funnel is attached to the tail end solely by frictional engagement between an inner portion of the funnel and at least one protrusion along the tail end;
- a plurality of circumferential grooves provided along the tail end;
- an eye slot extending from the tail end longitudinally along the shaft;
- an eye having a plurality of eye grooves, the eye flush within the eye slot so that the plurality of eye grooves aligns with the plurality of circumferential grooves;
- and
- a filament wrapped around at least one of the plurality of aligned grooves so as to protrude above a circumferential surface of the tail end.
