发明名称 Single hand actuated friction type box call
摘要 A compact one-handed thumb actuated friction type turkey call is formed generally of a rectangular, elongated hollow wooden sound chamber box assembly having longitudinally opposed side walls with a double longitudinally convex bottomed striker pivotally mounted to one end block at one end thereof for oscillation across the sound chambers opposed walls. The striker having the end opposite of the pivotal mount cut at an angle and having a rectangular shaped thumb tab affixed to the flat upper side angle cut end is actuated by the operator by holding the call across ones palm and pushing the thumb tab. A closed, looped, stretchable band biases the striker back to an open position which is slightly unparallel to the position of the sound chamber box when in the open position.
