Abstract
A flexible cover having magnetic attachment is provided for sealing openings in a structure such as a heating, ventilation and air conditioning duct, an automobile window, or an automobile door handle or lock. Magnets or another suitable affixing device are attached at the periphery on one side of the cover. Alternatively, the magnets may be attached to one side of the cover by sandwiching the magnets between two opposing flexible covers. Gaps between the magnets permit the flexible cover to attach to objects having a curved or angular conformation. In operation, the cover is placed over the opening preventing the transmission of air, fluid material, or particulate material through the opening.
Claims12
A flexible cover, comprising:
- a flexible sheet of material having an inner face, an outer face, opposite sides, and opposite ends;
- a plurality of magnets affixed to the inner face of said flexible sheet;
- wherein said magnets are placed at regular intervals along the edges of the inner face of said flexible sheet;
- and
- a space is left between said magnets, providing flexibility to said cover.
A method of sealing an opening having ferromagnetic periphery, which comprises the steps of:
- providing a first flexible sheet of material having an inner face, an outer face, opposite sides, and opposite ends;
- affixing a plurality of magnets located adjacent to said opposite sides and said opposite ends, including a flex space between each of said magnets;
- aligning the first flexible sheet over the opening;
- and
- attaching said magnet to the ferromagnetic periphery.
A method of sealing an opening having ferromagnetic periphery, which comprises the steps of:
- providing a first flexible sheet of material having an inner face, an outer face, opposite sides, and opposite ends;
- providing a second flexible sheet of material having an inner face, an outer face, opposite sides, and opposite ends;
- affixing a plurality of magnets located adjacent to said opposite sides and said opposite ends of said first and second flexible sheets, including a flex space between each of said magnets;
- providing a third and fourth flexible sheet of material, each having an inner face, an outer face, and opposite sides;
- affixing said third flexible sheet inner face attached to said first flexible sheet inner face sealing said magnets between said first and third flexible sheets;
- affixing said fourth flexible sheet inner face attached to said second flexible sheet inner face sealing said magnets between said second and fourth flexible sheets;
- aligning the second flexible sheet over the opening, partially overlapping the first flexible sheet;
- and
- attaching said magnet to the ferromagnetic periphery.
