  • Patent number: 6892994
    Abstract: A three-fingered holder having the ability to selectively and firmly grasp a variety of different objects. The holder comprises a housing, three fingers partially sheathed within and partially extending from the housing, and a spring-biased clamping mechanism contained within the housing. The mechanism has an open position wherein the fingertips of the fingers are substantially separated, but is biased toward a closed position wherein the fingertips are positioned in proximity to one another, in order to firmly grasp an object therebetween. The mechanism is converted to the open position by pressing down upon a lever. Release of the lever allows the spring-biased mechanism to return toward the closed position and to thereby urge the fingers towards one another. The fingertips each terminate in a soft rubber contact plate, which prevents even delicate objects from becoming damaged while being held by the holder.
