MOLE-TRAP Russian patent published in 1997 - IPC

FIELD: animal catching equipment. SUBSTANCE: mole-trap has elongated body 1 and shutters 2 which are suspended from horizontal axles at both ends of it and inside on its side walls. Suspension of shutter 2 by means of eye-lugs located at their upper part creates tilting moment and displaces center of gravity of shutter from vertical plane at certain angle towards inside it. Due to that, shutter is permanently kept in inclined position and entrance into mole-trap easily opens at slight push. Incline of shutters in reverse direction from vertical axis is impossible due to thrust shoulders on end faces of body and mole can not open shutter from inside. EFFECT: high efficiency. 6 dwg
