Abstract:
A door reminder for hangng on the shank of a doorknob on a door for delivering a message, comprising:a. a hanger which is a substantially elongated planar body portion of rigid material having a hanger opening, said hanger opening is a substantially centrally disposed opening extending perpendicularly through the plane of said planar body portion, said hanger opening having a predetermined shape and sufficient size to allow said doorknob to pass through, said hanger consists of an upper portion of hanger and a heavier lower portion of hanger, said lower portion of hanger being the portion of said hanger below said hanger opening when said hanger is hung vertically on the shank of said doorknob through said hanger opening such that said heavier lower portion of said hanger is below said doorknob and said upper portion of hanger being the portion of said hanger above said lower portion of hanger,b. a flap rotatably and horizontally mounted on said upper portion of hanger above said hanger opening, said flap having a flap opening of predetermined shape and sufficient size such that said doorknob can pass through said flap opening when said flap is rotated towards the surface of said hanger such that when said hanger is hanging on the shank of said doorknob, said hanger is located between said door and said flap,c. at least one electronic device which contains switch means for causing said electronic device to be actuated by the rotational movement of said flap, said electronic device having a function which can be utilized for delivering said message; andd. urging means for maintaining said flap at an operative angle above the surface of said hanger when said hanger is hanging on the shank of said doorknob and when said flap is not being moved, said operative angle being sufficiently large to ensure that a hand moving to grasp said doorknob will generate a rotational movement on said flap towards the surface of said hanger to turn on said switch means, said urging means being used for storing a portion of the energy generated by said hand for moving said flap towards the surface of said hanger and spending said portion of the energy to move said flap back to said operative angle to turn off said switch means when said hand is removed from said doorknob.
