Abstract
A french door refrigerator seal having vertically extending seal elements on the juxtaposed edges of the french doors defining an air space therebetween. Closure seals are provided at the upper and lower ends of the edge seals to close the air space and thereby define an insulative dead air space between the french door edge portions when the doors are in the closed position. The closure seals illustratively may be formed as overlapping flexible flaps carried by the vertical edge seal elements which illustratively may form pairs of flexible flaps.
Claims24
In a refrigeration apparatus having wall means defining a refrigerated space and having a front portion defining an access opening to said space, a pair of doors pivotally mounted in side-by-side relationship for selectively closing said access opening, and seal elements carried by portions of the doors which are juxtaposed when the doors are positioned to close said access opening outwardly of said wall means, said seal elements including outer portions cooperatively defining an outer seal and inner portions cooperatively defining an inner seal with an air space having upper and lower ends between said outer and inner seals when the doors are positioned to close said outer and inner seals when the doors are positioned to close said access opening, the improvement comprising:
- sealing closure means for closing said ends of said air space to define a dead air space between said doors outwardly of said wall means front portion when said doors are positioned to close said access opening.
In a refrigeration apparatus having wall means defining a refrigerated space and an access opening to said space, first and second doors pivotally mounted to said wall means for selectively closing said opening, said doors defining vertically extending edge portions which are juxtaposed when the doors are in a closed position across said opening, a first, outer pair of seals mounted one each to said door edge portions and extending therefrom into sealed engagement with each other when said doors are in said closed position, and a second, inner pair of seals mounted one each to said door edge portions and extending therefrom into sealed engagement with each other inwardly of said first pair of seals when said doors are in said closed position, said first and second pairs of seals defining an air space between said doors exteriorly of said refrigerated space and immediately forwardly of said access opening, the improvement comprising
- closure means carried by at least one of said doors for closing the top and bottom of said air space when said doors are in said closed position whereby said air space comprises an insulative dead air space closed at the top and bottom thereof.
In a refrigeration apparatus having wall means defining a refrigerated space and having a front flange defining an access opening to said space, a pair of doors pivotally mounted in side-by-side relationship for selectively closing said access opening, and flexible seal flaps carried by the vertically extending edge portions of the doors which are juxtaposed when the doors are positioned to close said access opening, said seal flaps defining upper and lower ends and including an outer pair defining an outer seal and an inner pair defining an inner seal, an air space being formed between said outer and inner seals, the improvement comprising:
- closure flaps on the upper and lower ends of said seal flaps and overlapping each other to close the ends of said air space when the doors are in the closed position to thereby define with said seal flaps a dead air insulating space along said juxtaposed door edges.
In a refrigeration apparatus having wall means defining a refrigerated space and having a front portion defining an access opening to said space, a pair of doors pivotally mounted in side-by-side relationship for selectively closing said access opening, improved means for sealing the space between said doors when said doors are positioned to close said opening, comprising:
- first seal means carried by said doors and including top and bottom sealing closure means, said first seal means cooperatively defining an outer closed dead air space forwardly of said wall means front portion;
- and
- second seal means carried by said doors and cooperatively defining with said wall means an inner closed dead air space within said access opening.
In a refrigeration apparatus having wall means defining a refrigerated space and having a front portion defining an access opening to said space, a pair of doors pivotally mounted in side-by-side relationship for selectively closing said access opening, improved means for sealing the space between said doors when said doors are positioned to close said opening, comprising:
- first seal means carried by said doors and cooperatively defining an outer closed dead air space forwardly of said wall means front portion;
- and
- second seal means carried by said doors and cooperatively defining with said wall means an inner closed dead air space within said access opening.
