Abstract
The storm window of the invention is adapted to be mounted in a window frame of a house interiorly of the existing window closure. It comprises a hollow structure made up of a plurality of components of thin flexible material, such as plastic sheet, in the form of a panel of substantial thickness with a periphery corresponding to the periphery of the window frame and inner and outer generally planar faces enclosing an insulating dead air space between them. At least part of the structure is inflatable to yieldingly enlarge the periphery and cause the panel to resiliently grip the window frame and retain the panel in position. The major portion of the planform area is substantially transparent to facilitate vision and light transmission through the panel. The structure may be deflated and folded into small compass for storage.
Claims12
A storm window adapted for mounting in the window frame of a house interiorly of the existing window closure, comprising:
- a general planar marginal framework of sealed flexible tubing having a planform corresponding in size and shape to the size and shape of the window frame and provided with at least one inflation port to supply air under pressure to its interior to yieldingly enlarge its periphery and cause it to grip opposing areas of the window frame and retain it in predetermined position;
- and closure means of thin flexible material extending across the framework at each side thereof and connected to it to form a hollow panel having a thickness substantially corresponding to the diameter of the tubing with substantially planar faces, and cooperating with the framework to define and enclose at least one substantially sealed dead air space to serve as insulation between the inner and outer walls of the panel;
- the closure means being substantially transparent to facilitate vision and light transmission through the panel.
An interior storm window construction comprising:
- a generally rectangular window frame in a house wall extending between the inner and outer margins of the wall;
- a window closure extending across the window frame in a general plane located between the inner and outer margins;
- and a hollow structure including a plurality of components of thin flexible material connected together to form a generally planar panel of substantial thickness presenting inner and outer walls which define and enclose a substantially sealed dead air space between them to serve as insulation between the inner and outer panel walls;
- the structure including a marginal framework of substantially transparent sealed thin flexible tubing corresponding in size and shape to the size and shape of the window frame interiorly of the window closure and a layer of substantially transparent thin flexible material overlying the framework at each side to define the composite hollow panel;
- the tubing being provided with an inflation port to supply air under pressure to its interior to yieldingly enlarge the periphery of the framework and cause it to frictionally grip opposing areas of the window frame and retain the structure in predetermined position;
- the panel being mounted in the window frame in such position that its outer confronting face is spaced from at least the major portion of the area of the window closure by a substantial distance to produce a second dead air insulating space between them.
