Abstract
A magnetically sealed sliding window system including a perimetric frame including header and base portions each defining a narrow channel for receiving a glazing pane and an adjacent second channel. A sliding panel is seated within the second channel. Longitudinal magnets are secured on the inner face of the sliding panel. Where the perimetric frame is formed of nonmagnetic material, magnets also are secured along the header and base second channel sections. No magnets are required on the perimetric frame when same is formed of magnetic material such as steel. In sealed condition, the sliding panel is positioned above the floor of the base channel with the panel magnetically held. The magnets have longitudinally extending magnetic poles establishing a magnetic coupling between adjacent unlike poles. The height of the sliding panel is less than the height of the frame. Translation of the sliding panel first in a vertical direction, shifts the adjacent magnetic polarity so that repulsion force causes the sliding panel to be displaced into an offset vertical plane, disengaging the magnets dropping the sliding panel into the base channel and freeing same for translation in a horizonta…
