other positions of rotating holes 123 and 160 are capable of accommodating only the essentially circular lower portions 128 168 and actuator button 122 which are presented to holes 123 and 160 when push button 108 is in the upward locked child resistant condition the operation of this embodiment of the invention may also be understood by reference to fig8 through 14 to unlock the child resistant feature outer rotatable member 120 is rotated in a clockwise viewed from above direction sufficiently to rotate notch 165 in the circumference of hole 160 in inner rotatable member 119 into alignment with rectangular projection 170 on the actuator button 122 the inner rotatable member 119 is temporarily held in this position by frictional engagement of lower surface with an upper surface of relatively stationary top cover 112 only a small amount of frictional engagement is required because no tangential force is exerted on inner rotatable member 119 other than that exerted by interaction with outer rotatable member 120 outer rotatable member 120 is then rotated in the counterclockwise direction to align notch 125 in the circumference of hole 123 in outer rotatable member 120 with rectangular projection 170 on relatively nonrotating actuator button 122 actuator button 122 may then be depressed thus depressing push button 108 and allowing the release of tongue 105 from body 102 of buckle 101 when downward pressure on push button 108 is released push button 108 and actuator.
