Abstract
An apparatus for selectively moving a transparent pane and a screen pane across a window opening includes first and second mechanisms for moving the transparent and screen panes, respectively, from a respective first position covering the opening, and inhibiting means for preventing the movement of the screen pane from the first and second positions thereof upon the transparent pane occupying a position other than the latter's first position but not yet at the second position.
Claims1
An apparatus for selectively moving a transparent pane and a screen pane across a window opening comprising:
- first and second mechanisms for moving said transparent and screen panes, respectively, from a respective first position leaving the opening uncovered, to a respective second position covering said opening, said mechanisms including respective segmental gears disposed on one side of the panes, respective pinions engaging said gears, each of said pinions including a handle for the rotation thereof, and wherein said panes have respective lower end portions formed with a longitudinal slit, and each of said gears includes an arm rigid therewith having an end thereof adapted to slide within one of said slits, and
- inhibiting means for preventing the movement of said screen pane from the first and second positions thereof upon said transparent pane occupying a position other than the latter's first position but not yet at the second position, said inhibiting means including first belt-means, first belt-supporting means attached to a door frame for said first belt-means to be movable by the handle of said first mechanism, second belt-means and second belt-supporting means attached to the door frame for said second belt-means to be movable by the handle of said second mechanism, said first belt-means having narrower and wider portions of first and second lengths, respectively, and said second belt-means having a plurality of substantially equispaced longitudinal pins thereon, and being disposed transversely to said first belt-means, and wherein said second length of said wider portion of said first belt-means is operatively contactable by at least two successively spaced pins, said narrow portion being operatively non-contactable by said pins, said second length of said wider portion corresponding to the distance for said transparent pane to operatively move from said first to said second position, whereby a rotation of one of said handles causes the handle-associated pane to move across the window opening and the handle of said second mechanism is substantially prevented from being rotated upon said wider portion of said first belt-means being interposed between said two successively spaced pins.
