Abstract

A patch for a ducting wall has two sealing portions, one of which may be bent to pass through a torn opening in the ducting wall. When jointed by a coupling means, the two sealing portions may pinch the ducting wall surrounding the torn opening and provide a barrier against the escape of air through the opening.

Claims (13)

1. A patch for sealing an opening in a thin wall of pinchable material comprising:
(1) two cooperative sealing means at least one of the sealing means being sufficiently flexible to be bent and being of a size which:
(a) when bent can be passed through an opening in the wall; and (b) when expanded will span the opening in the wall;
both sealing means being sufficiently rigid to provide at their peripheries a sustained pinching force on a wall surrounding the opening when these two sealing means are drawn towards each other from opposite sides of said wall so as to fix the sealing means in relationship to the pinched portion of said wall;
(2) air barrier means carried by at least one of said sealing means to block passage of air through said opening; and (3) coupling means extending between said first and second sealing means to provide said sustained pinching force on the pinched wall.
2. A patch as in claim 1 wherein at least one of the sealing means is provided with ribs to enhance its rigidity.
3. A patch as in claim 1 wherein at least one of the sealing means is provided with corrugations to enhance its rigidity.
4. A patch is in claim 1 wherein the coupling means is a rod with a shaft and an enlarged end, said shaft passing through a hole in one of said sealing means.
5. A patch as in claim 4 wherein at least one, first, of said sealing means is generally dome-like in shape with said hole centrally placed to receive the shaft of the coupling rod and wherein said first sealing means has an outer, first periphery to apply the sustained pinching force.
6. A patch as in claim 5 wherein the second sealing means is generally flat with a central hole to receive the shaft of the coupling rod and said second sealing means has an outer second periphery to apply or sustained pinching force.
7. A patch as in claim 6 wherein the outer, second periphery is provided with a flange to cause the pinched wall to conform to a tortuous path while passing between the two sealing means.
8. A patch as in claim 7 wherein the outer edge, first periphery of the domed sealing means is interrupted by generally radial cuts to allow such outer, first periphery to expand towards the flange formed on the second sealing means.
9. A patch as in claim 1 wherein:
(1) at least one, first, sealing means is generally dome-like in shape with a domed body and a circular, outer periphery that is interrupted by generally radial cut lines that allow segments of said periphery to expand outwardly upon the application of pressure to the domed-body of the first sealing means; and (2) the second sealing means has an inwardly inclined outer lip towards which the segments of the periphery of the first sealing may expand whereby material pinched therebetween with be forced to confirm to an "S"-shaped curvature path.
10. A patch as in claim 1 in combination with a duct having said thin wall, the wall comprising a flexible fabric.
11. A patch as in claim 7 in combination with a duct having said thin wall, the wall comprising a flexible fabric.
12. A patch as in claim 8 in combination with a duct having said thin wall, the wall comprising a flexible fabric.
13. A patch as in claim 9 in combination with a duct having said thin wall, the wall comprising a flexible fabric.
