Abstract
A spring powered roll type fiberglass window screen has side edges received in guide channels in which locking bars are pivotally and slidably received. In closing the screen, the locking bars are longitudinally slidable by a screen actuator which in turn causes the locking bars to be pivoted into engagement with the screen by action of a guide actuator tab engaging a cam surface on the locking bar. In opening the screen, the screen actuator moves the locking bar upwardly until it is pivoted out of engagement therewith by a guide cam surface on the guide channel whereupon the screen is free to move to a fully raised position, leaving behind the locking bar.
Claims24
A rolling window screen assembly installed in a window frame, said frame including a sill, a head and side jambs, said assembly comprising,
- a screen mounted on said window frame adjacent said head and being rollable along said jambs of said window frame between raised and lowered positions, said screen having opposite side edges, an upper edge, a lower edge and opposite interior and exterior surfaces,
- a pair of elongated guide means mounted extending along each of said side jambs for guiding said opposite edges of said screen while said screen is unrolled along said jambs,
- locking bar means associated with said guide means for selectively engaging said screen side edge to limit movement of said screen and to provide a seal between said screen and said guide means, and
- said screen includes an actuator means which engages said locking bar means when said screen has been moved downwardly to said lowered position causing said locking bar means to engage said screen side edge as a result of said downward movement.
