ABSTRACT:
A door knob has a generally spherical flattened configuration with a front face provided with a representation of a human eye. The eye may be integrally formed with the door knob or bonded thereto. Various portions of the eye may be treated with a luminescent or phosphorescent paint such that the eye will glow in the dark. The door knob serves as a novelty item which also functions as an indicator for the position of the door knob at night due to the luminescent or phosphorescent treatment. In a second embodiment, the human eye representation is separately formed as a cylindrical plug rotatably mounted in a circular aperture formed through a front face of the door knob. A key hole is formed centrally through the pupil of the eye in alignment with a conventional lock cylinder. The glowing eye serves as a position indicator at night time to indicate the position of the key hole. In a third embodiment of the invention, the human eye is mounted for limited axial movement and serves to actuate a bellows type sound producing mechanism within the door knob.
