Ventilation device

Claim 2

A portable ground air ventilation scoop in combination with an aircraft window and for ready insertion in said aircraft window when there is a flow of air past said ventilation device primarily in one direction, said combination comprising, a. said portable ground air ventilation scoop having an outer rigid portion peripherally surrounding at least a portion of an inner flexible portion and physically connected thereto, said outer rigid portion having an outer physical dimension greater than the opening created by said aircraft window, b. said inner flexible portion having at least one portion thereof having a lineal physical dimension greater than the distance between first points on said outer rigid portion where said flexible portion connects at said first points on said outer peripheral rigid portion, said flexible inner portion having a degree of flexibility sufficient to allow the flexible portion to fold upon itself in substantially a plane containing said outer rigid portion to thereby provide a flat, easy to store, and readily portable ventilation device.

Claim 3

The portable air ventilation scoop of claim 1, wherein said inner flexible portion has at least a second portion thereof having a lineal physical dimension substantially equal to the distance between second points on the outer rigid portion where said flexible portion connects to said outer peripheral rigid portion to thereby form a ground air ventilation device whenever said flow of air is in the direction of said second points from said first points.

Claim 4

The portable air ventilation scoop of claim 2, wherein said peripheral portion circumferentially surrounds said flexible inner portion.

Claim 5

The portable air ventilation scoop of claim 1, wherein said peripheral portion circumferentially surrounds said flexible inner portion.

Claim 6

The portable air ventilation scoop of claim 1, wherein said outer rigid portion is comprised of two units with at least a portion of said flexible inner portion interposed therebetween and mutually connected to said two units to provide an integral outer rigid portion

Claim 7

The portable air ventilation scoop of claim 1, wherein said flexible inner portion has integral therewith structural reinforcing regions to provide for physical stability during the passage of air from said first point toward said second point while resisting structural flexure from forces directed by air movement coming from different directions.

Claim 8

The portable air ventilation scoop of claim 1, wherein positioned and integral therewith on said outer rigid peripheral portion is at least one flange element that protrudes into the window opening thereby enhancing the positioning and retention of said portable air ventilation scoop in said aircraft window.

Claim 9

The portable air ventilation scoop of claim 1, wherein said flexible inner portion has integral therewith a structural reinforcing region of a resilient nature such that said resilient reinforcing region is located substantially and integral with said inner flexible portion between said first point oN said outer peripheral rigid portion.

Claim 10

The portable air ventilation scoop of claim 1, wherein said inner flexible portion has an integrally connected tab portion means located on an inner surface of said flexible portion to allow the manual withdrawal of said flexible portion into and through said outer peripheral portion.

Claim 11

A ventilation device for use in an environment where there is a flow of a fluid medium past said ventilation device primarily in one direction, said device comprising, a. an outer rigid portion peripherally surrounding at least a portion of an inner flexible portion and physically connected thereto, b. said inner flexible portion having at least one portion thereof having a lineal physical dimension greater than the distance between first points on said outer rigid portion where said flexible portion connects at said first points on said outer peripheral rigid portion, said flexible inner portion having a degree of flexibility sufficient to allow the flexible portion to fold upon itself in substantially a plane containing said outer rigid portion to thereby provide a flat, easy to store, and readily portable ventilation device, said inner flexible portion having at least a second portion thereof having a lineal physical dimension substantially equal to the distance between second points on said outer rigid portion where said flexible portion connects to said outer peripheral rigid portion to thereby form a flexible fluid medium ventilation device whenever said flow of said fluid medium is in the direction of said second points from said first points, said inner flexible portion also having a number of preset creases which are substantially longitudinal of the inner flexible portion.

Claim 12

A ventilation device for use in an environment where there is a flow of a fluid medium past said ventilation device primarily in one direction, said device comprising, a. an outer rigid portion peripherally surrounding at least a portion of an inner flexible portion and physically connected thereto, b. said inner flexible portion having at least one portion thereof having a lineal physical dimension greater than the distance between first points on said outer rigid portion where said flexible portion connects at said first points on said outer peripheral rigid portion, said flexible inner portion having a degree of flexibility sufficient to allow the flexible portion to fold upon itself in substantially a plane containing said outer rigid portion to thereby provide a flat, easy to store, and readily portable ventilation device, said inner flexible portion having at least a second portion thereof having a lineal physical dimension substantially equal to the distance between second points on said outer rigid portion where said flexible portion connects to said outer peripheral rigid portion to thereby form a flexible fluid medium ventilation device whenever said flow of said fluid medium is in the direction of said second points from said first points, said inner flexible portion also having a number of preset creases which are substantially longitudinal of the inner flexible portion.

Claim 13

A ventilation device for use in an environment where there is a flow of a fluid medium past said ventilation device primarily in one direction, said device comprising, a. an outer rigid portion peripherally surrounding at least a portion of an inner flexible portion and physically connected thereto, b. said inner flexible portion having at least one portion thereof having a lineal physical dimension greater than the distance between first points on said outer rigid portion where said flexible portion connects at said first points on said outer peripheral rigid portion, said inner flexible portion having a degree of flexibility sufficient to allow the flexible portion to fold upon itself in substantially a plane containing said outer rigid portion to thereby provide a flat, easy to store, and readily portable ventilation device, said inner flexible portion having an integrally connected tab portion means located on an inner surface of said flexible portion to allow the manual withdrawal of said flexible portion into and through said outer peripheral portion.

Claim 14

A ventilation device for use in an environment where there is a flow of a fluid medium past said ventilation device primarily in one direction, said device comprising, a. an outer rigid portion peripherally surrounding at least a portion of an inner flexible portion and physically connected thereto, b. said inner flexible portion having at least one portion thereof having a lineal physical dimension greater than the distance between first points on said outer rigid portion where said flexible portion connects at said first points on said outer peripheral rigid portion, said inner flexible portion having a degree of flexibility sufficient to allow the flexible portion to fold upon itself in substantially a plane containing said outer rigid portion to thereby provide a flat, easy to store, and readily portable ventilation device, said inner flexible portion having an integrally connected tab portion means located on an inner surface of said flexible portion to allow the manual withdrawal of said flexible portion into and through said outer peripheral portion.
