| Abstract: |
A paint ball land mine capable of propelling standard caliber paint balls during simulated war games is disclosed. The present paint ball land mine is designed to simulate the function of a U.S. military Claymore anti-personnel mine for purpose of marking participants as out of the competition in the simulated war game. The paintball land mine includes a cylindrical discharge tube configured to receive a pyrotechnic charge in the form of a 12 gauge shotgun blank round and/or a .38 caliber blank round. In a preferred embodiment a firing pin is pivotally attached in operative relation to the pyrotechnic charge and spring-biased into contact therewith. A trigger mechanism including a trip pin fixedly attached to a trip wire is interposed between the pyrotechnic charge and the firing pin. When a participant comes into contact with the trigger mechanism the paintballs are propelled at a velocity up to 200 feet per second.

What is claimed is:
1. A paint ball land mine for propelling a paint cartridge with a detonation cartridge when contacted by a participant in a ground area, said paint ball land mine comprising: a base member for engaging the ground area; a cylindrical discharge tube on said base member defining a cylindrical bore having a discharge end and a cartridge end for receiving the detonation cartridge, the detonation cartridge having a detonation member facing outwardly of said base member; a retaining member connected to said base member adjacent said cartridge end and shiftable from a loading position permitting insertion of the detonation cartridge into said bore and a detonation position retaining the detonation cartridge in said bore; a pivot member pivotally connected to said base member and carrying a detonation pin for engaging the detonation member to initiate detonation thereof and propel the paint cartridges from said discharge tube, said pivot member having an armed position spaced from said base member and a detonation position whereat said detonation pin engages said cartridge member; a trip member extending between said base member and an outer end of said pivot member for maintaining said pivot member in said armed position; spring means operative for biasing said pivot member between said armed position and said detonation position; an a trip wire extending between said trip member and the ground area whereby contact of said trip wire by the participant will dislodge said trip member from said pivot member permitting said spring means to shift said pivot member from said armed position and said detonation position causing said detonation pin to engage said cartridge member thereby initiating detonation and propelling said pain cartridges from said tube.
