  • a conventional floor hinge of the type described above comprises means for attaining a delayed action function capable of slowly closing the door from a fully open state to a certain open angle state, means for closing the door at a normal closing speed, i.e. first closing speed, from the certain open angle state of the door to an open angle close to a position where the door is completely closed and means for closing the door at a second closing speed lower than the first closing speed.
  • Another conventional floor hinge is further provided with means for achieving a latching action capable of speedily closing the door at angles of about 2° to 3° just before the door has been closed to completely close the same.
  • a further conventional floor hinge is provided with means for attaining a back check function for prevention of rapid opening of the door to the door with an open angle between a certain open angle to the fully open angle so as to prevent the door, a knob of the door or a wall to which the door is attached from being damaged by an accidental rapid opening of the door by an external force, for example.
