Modular window insert with collapsible shade

Claim 2

A modular window insert unit comprising: means defining a curved inner window pane formed of impact resistant plastic; means defining a curved outer window pane formed of impact resistant plastic; a curved frame assembly securing said inner and outer window panes in spaced, generally parallel relation; collapsible shade means comprising a plurality of collapsible tubes formed from a compressed polymer material, said tubes being attached along complementary edges, each of said tubes being substantially collapsed when said shade is in a first position, and each of said tubes having a substantially hexagonal cross-section when said shade is in a second position, said shade being secured in said frame assembly between said inner and said outer panes; actuator means for moving said collapsible shade from said first position to said second position.

Claim 3

A modular window insert according to claim 1, said frame assembly comprising a generally rectangular inner frame and outer frame defined by a molded outer faceplate, said outer faceplate comprising a bezel for securing said outer window pane to said frame assembly, said outer faceplate and said bezel being adapted to conform to the contour of an aircraft cabin, said inner frame and said outer frame being attached along complimentary outer peripheral edges, thereby defining a seal for preventing the entry of dust and other foreign matter into the interior of the window unit.

Claim 4

A modular window insert according to claim 1, said collapsible shade means having first and second ends, said first end attached to an edge of said curved frame assembly, said second end attached to a support rail, said collapsible shade means being extendible along a longitudinal axis from said first position to said second position, with a plurality of transverse air channels being defined by the interior of said collapsible tubes said collapsible shade means in said second position.

Claim 5

A modular window insert according to claim 3, said actuator means comprising a peripheral cable assembly slidably secured along the peripheral edges of said frame assembly and further secured to said support rail.

Claim 6

A modular window insert according to claim 4, said actuator means further comprising an electric motor for moving said cable assembly and thereby moving said shade from said first position to said second position.

Claim 7

A modular window insert according to claim 4, said actuator means further comprising a fluid cylinder means for moving said cable assembly and thereby moving said shade from said first position to said second position.

Claim 8

A modular window insert according to claim 1 further comprising an alignment maintenance means wherein said alignment maintenance means comprises a first cable and a second cable, said cables attached at a first end to an upper frame support member, said cables then depending downward perpendicular to the longitudinal axes of said tubes through apertures therein, through a lower shade rail with apertures therein, said lower shade rail having a bottom side, said cables then directed to opposite ends of said shade rail in a manner which criss-crosses said cables along said bottom side of said shade rail, said cables then directed downward to and rigidly attached under tension to a lower frame support member.

Claim 9

A modular window insert unit for use in the cabin of an aircraft or other vehicle, comprising: a curved inner window pane; a curved outer window pane; a frame assembly for securing said inner and outer window panes in spaced relation with opposing faces of said inner and outer window panes being separated by a substantially uniform distance, said frame assembly comprising a generally rectangular inner frame and an outer frame defined by a molded outer faceplate, said outer faceplate having a bezel on an interior portion thereof for securing said outer window pane, said inner and outer frames being attached along complimentary peripheral edges, thereby defining a seal for preventing the entry of dust and other foreign material into the interior of the window unit; a generally rectangular mask secured within said frame assembly between said inner and outer window panes; a collapsible shade means secured within said frame assembly between said inner and outer window panes, said shade comprising a plurality of collapsible tubular members, said shade extendible between a first position wherein said tubular members are collapsed and a second position wherein said tubular members define a plurality of transverse channels of air contained within said shade; actuator means for moving said shade between said first position and said second position.

Claim 10

A modular window insert unit for use in the cabin of an aircraft or other vehicle, comprising: a curved inner window pane; a curved outer window pane; a frame assembly for securing said inner and outer window panes in spaced relation with opposing faces of said inner and outer window panes being separated by a substantially uniform distance, said frame assembly comprising a generally rectangular inner frame and an outer frame defined by a molded outer faceplate, said outer faceplate having a bezel on an interior portion thereof for securing said outer window pane, said inner and outer frames being attached along complimentary peripheral edges, thereby defining a seal for preventing the entry of dust and other foreign material into the interior of the window unit; a generally rectangular mask secured within said frame assembly between said inner and outer window panes; a collapsible shade means secured within said frame assembly between said inner and outer window panes, said shade comprising a plurality of collapsible tubular members, said shade extendible between a first position wherein said tubular members are collapsed and a second position wherein said tubular members define a plurality of transverse channels of air contained within said shade; actuator means for moving said shade between said first position and said second position.
