  • Patent number: 4821542
    Abstract: An apparatus for positioning a key at the keyhole of a lock. The apparatus includes a hollow, funnel-shaped element having a wide end and a narrow end. The wide end defines a wide opening which is sufficiently large, and the funnel-shaped element is sufficiently deep, to permit the partial introduction of the index finger and thumb of the user holding the key into the funnel-shaped element. The apparatus also includes means for securing the funnel-shaped element in a position adjacent the keyhole so that the narrow end is located adjacent the periphery of the keyhole during use. The narrow end defines an opening which is larger than the keyhole but sufficiently narrow to enable the user to accurately locate the keyhole.
