发明名称 Safety loading unit for ceiling track with easy to use latching
摘要 The present disclosure is concerned with an improved latching mechanism for the hinged section of a ceiling track for traveling curtain. The latching mechanism is designed to make a readily audible sound when it is locked. It is based upon a generally oval shaped lock knob which passes through a generally oval shaped aperture in the bottom wall of a receiver for the lock knob. The aperture is designed so that when the lock knob is rotated its long axis no longer aligns with the long axis of the aperture it can no longer pass through the aperture. The bottom wall of the receiver carries two upwardly extending side walls that must be pushed outward to allow the passage of the lock knob as it rotates and that carry gaps that accommodate the tips of the lock knob and allow the side walls to move back toward their undeformed position.
