Safety fitting attachment assembly embodying components with distortable thread means

Abstract

Abstract AN IMPROVED SAFETY FITTING ATTACHMENT ASSEMBLY FOR DETACHABLY MOUNTING VARIOUS FITTINGS, SUCH AS REAR VIEW MIRRORS IN AUTOMOBILES, WHICH FITTING ASSEMBLY IS CAPABLE OF ADSORBING IMPACTS AND PERMITTING THE FITTING TO BECOME DISLODED OR SEPARATED FROM ITS MOUNTING OR SUPPORT WHEN SUBJECTED TO RELATIVELY INTENSE IMPACTS OF A PREDETERMINED STRESS VALUE. THIS IS ACHIEVED BY PROVIDING A MALE-THREADED RELATIVELY FLAT CYLINDRICAL BASE FOR ATTACHMENT, AS BY A SUITABLE ADHESIVE TO A SUPPORT SURFACE, AND FURTHER PROVIDING AN ANNULAR COMPLEMENTALLY THREADED COLLAR WHICH FITS OVER AND COMPLEMENTALLY COOPERATES WITH A BASE FLANGE PORTION OF A FITTING OR MOUNTING STAY MEMBER TO HOLD THE STAY ONTO THE MOUNTED CYLINDRICAL BASE. THE COMPLEMENTAL THREADED PORTIONS BEING OF A RELATIVE SIZE AND CHARACTER WITH AT LEAST ONE OF THEM BEING FABRICATED OF A PLASTIC MATERIAL TO PERMIT A NONROTATIVE GENERALLY AXIAL OR OBLIQUE SEPARATION THEREOF RESPONSIVE TO AN APPLICATION OF A PREDETERMINED FORCE THEREAGAINST, AS A SAFETY PRECAUTION TO PRECLUDE INJURY AS BY PERSONAL EGAGEMENT AGAINST AN OTHERWISE NORMALLY OR RELATIVELY IMMOVABLE OBJECT. THE CYLINDRICAL BASE AND FLANGE OF THE MOUNTING STAY MAY HAVE COMPLEMENTAL INTERENGAGING MEANS TO POSITIVELY ORIENT AND PRECLUDE RELATIVE ROTATIVE MOVEMENT OF THE BASE AND FLANGE WHEN HELD IN FULLY ASSEMBLED CONDITION BY SAID COLLAR, AND MAY FURTHER INCLUDE COMPLEMENTAL COOPERATING MEANS SUCH AS STRAIGHT KNURLED PORTIONS ON THE FLANGE OF THE MOUNTING STAY AND ON A PORTION OF SAID COLLAR TO EFFECT A LOCKING ACTION TO PRECLUDE INADVERTANT UNSCREWING OF THE ASSEMBLED FITTING COMPONENTS.
