Alarm device for a campsite

An alarm device for a campsite, comprising a plurality of spaced apart tubes, which are placed so as to encompass the campsite, a pair of caps fixedly secured at their end walls to each other, one each of said pair of caps being removably received on one end of said tubes, and a spike, pointed at each end, is fixedly secured within said end walls on the longitudinal axis of each of said pair of caps, one end of said spike being entered into the ground and the other end serving as support and firing pin means for a primer within each of said tubes, and a trip pin is slidably and removably received transversely through an opening near the upper end of said tubes, said trip pins each being secured to an end of a cord on the exterior of said tubes, the opposite end being tied to the outer periphery of the adjacent tube of the plurality of said tubes, and said trip pin abuts against and supports a gravity actuated weight in said tubes until an intruder strikes said cord of said trip pin, said trip pin being removed from the support position of said gravity actuated weight by the cord being pulled by the intruder striking said cord, and said gravity actuated weight descends downwards in said tube and, by inertia means, forcibly urges said primer against the pointed end of said spike within said tube, thus firing said primer, the gases of the explosive report of said primer being discharged through a plurality of radially spaced apart ports through the wall of said tube, which will alert the camper, and a cap is fixedly secured to the upper end of each of said tubes to prevent precipitation from entering the said tubes and said caps fixedly secured to the upper end of each of said tubes, in conjunction with said pair of caps, provides storage means for said gravity actuated weight, said trip pin, said cord and a plurality of said primers when entered into said tubes, and said pair of caps when inverted and replaced on said tube will enclose the portion of said spike within one tube, that is normally entered into the ground.
