Safety door assembly and method for child door safety

A door assembly apparatus comprising:

• a main door,
• a doorframe comprising a hollow rectangular cuboid of four paired surfaces, specifically, inner and outer top surfaces, inner and outer rear surfaces, inner and outer threshold surfaces, and inner and outer front surfaces;
• a major pivotal means,
• a leaf door,
• a minor pivotal means, and
• a spring mechanism,
• a major latching mechanism and
• a minor latching mechanism, wherein
• a) said main door comprises, as a major pivotal means, an integral axle, having an upper end and a lower end, said axle attached to and parallel to the trailing edge of said main door, said main door further having a rectangular cutout excised from, and parallel to, the leading edge of said main door;
• b) said doorframe comprises a hollow rectangular cuboid of four paired surfaces, specifically, inner and outer top surfaces, inner and outer rear surfaces, inner and outer threshold surfaces, and inner and outer front surfaces;
• c) said doorframe further comprises i) an upper bearing assembly for reception of the upper end of said axle, said upper bearing assembly integral to the inner top surface of said doorframe proximate the junction of the inner top surface and the inner back surface of said doorframe, and ii) a lower bearing assembly for reception of the lower end of said axle, said lower bearing assembly being integral to said inner threshold surface, proximate the junction of the inner threshold surface and the inner back surface of said doorframe;
• d) said leaf door comprises dimensions commensurate with a flush fit within the indentation in said main door, and further having a minor pivotal means, said minor pivotal means connecting said leaf door to the cutout in said main door;
• e) said main door, when rotated about the rotational axis of said major pivotal means and closed within said doorframe, may be attached to at least one inner surface of said doorframe by said major latching mechanism;
• and
• f) said leaf door, when rotated about the vertical axis of said minor pivotal means to a position flush with said main door, may be fixed to said threshold of said main door by said minor latching mechanism.

A method for improving safety with respect to the potential for severe finger injuries in the area of the immediate vicinity of a residential or commercial doorway, said doorway fitted with a conventionally operating door, the improvement being the installation of a door assembly comprising

• a main door having a convex-shaped trailing edge and having a rectangular cutout proximate the leading edge of said main door;
• a doorframe having a rectangular shape with four inner surfaces and dimensions suitable to accommodate said main door, and further, having an elastomeric material affixed to the inner rear surface;
• a major pivotal means for said main door;
• a leaf door of dimensions suitable for fit within said cutout;
• a minor pivotal means for operation of said leaf door;
• a spring mechanism of adequate tension to align said leaf door flush with said main door and having compression relief suitable to retract said leaf door;
• a major latching mechanism;
• and
• a minor latching mechanism.
