Hand and finger protector for use with doors
This invention relates to an apparatus and to a method designed to prevent hand and finger injuries resulting from inadvertent door closures. The apparatus for use with an existing door and door surround includes a door latching mechanism mountable to the door having a reversibly extendable bolt actuated by a turning member, a striker member mountable to the door surround wherein a portion of the striker member projects beyond the door surround, and when the bolt is extended, complete door closure is impeded by the projecting portion of the striker member with a gap width created between the leading edge of the door and the door surround sufficient to protect human hands and fingers from being crushed, injured, or amputated. When the bolt is intentionally retracted complete door closure is permitted. The apparatus is designed to be interchangeable with standard sized door knobs, latching mechanisms, lock assemblies, and striker plates.
