  • Patent number: 8656642
    Abstract: Disclosed is a door assembly comprising a custom-built doorframe housing a main door which carries an integrally mounted, rectangularly-shaped leaf door. The trailing edge of the main door rotates about a vertical axis which is parallel to, and proximate the inner rear surface of the doorframe. The leaf door is rotatably attached, by a spring mechanism, to a cutout excised from the leading edge of the main door. As the main door rotates about its vertical axis, the leaf door is restrained, by tension of the spring mechanism, from closing with full force upon human fingers or any other object that may be proximate the door jamb, or inner doorframe area. The pivoting, or trailing edge of the main door may be abutted against elastomeric material affixed to the inner rear surface of the doorframe, thereby preventing the insertion of fingers into what otherwise would be a hazardous gap.

    Abstract: This inventive concept discloses a door assembly comprising a custom-built doorframe housing a main door, which main door rotates within the doorframe by a major pivotal means. A spring-loaded leaf door is attached, by a minor pivotal means, within a cutout excised from the leading edge of the main door. As the main door rotates about its pivotal axis, the door is restrained from closing with full force upon human fingers or any other object that may be proximate the door jamb, or inner doorframe area. The pivoting, or trailing, edge of the main door is abutted against elastomeric material affixed to the inner rear surface of the doorframe, thereby serving to prevent the insertion of fingers into what otherwise would be a hazardous gap. The optimal embodiment of this inventive concept features a doorframe having upper and lower ball bearing assemblies for containment and stable support of the main door pivotal means.
