Abstract:
A two-way hingeless ventilator configured for defining a sealable ventilation path through a wall member, said ventilator comprising:a frame, said frame defining an opening therethrough; a closure member disposed against an outer side of said frame and swingable relative to said frame between an open and closed position; a stationary tensioning rod fixed on said frame so as to extend between opposite sides of said opening; an actuating member extending from an inner side of said closure member through said opening and intermediate ends of said tensioning rod; a positioning slot defined in said actuating member through which said tensioning rod passes in a tensioned condition to apply a closing force to said closure member, said positioning slot comprising a closed position and at least one side slot extending away from said closed position in a first direction and at least one additional side slot extending from said closed position in a different direction; and wherein said closure member is variably movable relative to said stationary tensioning rod from said closed position to an open position along either said side slot by an operator manually moving said actuator.
