Creature with snap action jaw

摘要

A creature with snapping jaws is comprised of a pair of body members defining a body cavity. The lower body member defines a lower jaw portion, an upper jaw member which has a lever arm extending into the cavity at one end, and disposed thereover is wherein it is pivotally mounted for pivotal motion relative to the lower jaw. Also pivotally mounted in the body cavity is an actuator with a button portion projecting through an aperture in the top of the body member and a cam portion which is engageable with the lever arm to produce pivotal movement thereof to open the upper jaw. Biasing means normally biases the upper jaw member into its closed position over the lower jaw portion and the button portion into an elevated position. When the button portion is depressed by finger action, the upper jaw member is opened by the cam action and at a point of maximum opening, the upper jaw member moves clear of its cam surface and snaps shut. Release of pressure on the button portion allows the actuator to return to its position.
