PRESS-FIT STORM WINDOW SYSTEM HAVING CONTROLLED BLOWOUT
Embodiments of the present invention are directed to a storm window having a controlled blowout mechanism. In some embodiments a blowout from wind pressure is controlled by the shape and orientation of a rigid window panel. Other embodiments include a venting portion with the storm window. Other embodiments rely on variation in restorative force within resilient material used to make the storm window.
1 . A storm window system for mounting within a window frame of an existing window, comprising:
a rigid panel having a front surface, a rear surface, and one or more edge surfaces;
a deformable material disposed along at least some portions of the edge surfaces of the rigid panel, the deformable material including a yieldable portion and a panel supporting portion, the panel supporting portion of the deformable material structured to secure the deformable material to the rigid panel; and
a blowout control mechanism.
2 . The storm window system of claim 1 in which the blowout control mechanism is a curved portion formed in the rigid pane.
3 . The storm window system of claim 2 in which the blowout control mechanism relies on different restorative forces in various portions of the deformable material mounted in respective various positions along the rigid panel.
4 . The storm window system of claim 2 in which the blowout control mechanism relies on different frictional forces in various portions of the deformable material mounted in respective various positions along the rigid panel.
5 . The storm window system of claim 4 in which at least some portions of the deformable material include ribs.
6 . The storm window system of claim 1 in which the blowout control mechanism is a relief vent.
7 . The storm window system of claim 6 in which the relief vent is formed in the resilient material.
8 . The storm window system of claim 6 in which the relief vent is formed in the rigid panel.
9 . The storm window system of claim 1 further comprising a window retention mechanism coupled between the rigid panel and a window frame.
