Abstract

A door releasably mounted to a wall forming a part of an enclosure of a chamber of a sealed incubator system. The door is supported on a floor on casters so as to enable the door, in its entirety, to be moved on the floor into and out of a door opening in the wall. The door opening has jambs, and the door has sides and a top. Gaskets mounted to the door sides and the door top bear against the door sides and the door top bears against the door jambs when the door is located in the door opening to seal the sides and the top of the door in the door opening, and permanent magnets embedded in the gaskets are magnetically attracted to the door sides and the door top to releasably retain the door in the door opening. A resilient strip mounted to the bottom of the door bears against the floor to seal the bottom of the door in the door opening. The casters are mounted on brackets that are attached to the door opening. The door and the brackets are assembled by mounting the brackets to the door while the door is propped in the door opening with the sides and the top of the door bearing against the door jambs, and the bottom of the door spaced from the floor in such a manner that the casters are supported on the floor.

Claims

1. An arrangement for providing access to a sealed incubator system comprising:

a wall, adapted to enclose a chamber of said system, extending upwardly of a floor;

an opening in said wall formed of a pair of spaced side jambs extending upwardly of the floor and a top joint spanning the upper ends of the side jambs;

a door, removably mounted in said opening, having a pair of spaced sides located proximate to said side jambs and a top located proximate to said top jamb;

first sealing means interposed between the side jambs and the door sides and between the top jamb and the door top to seal the sides and the top of the door opening;

releasable retaining means interposed between the door and the door opening for releasably retaining the door in the opening;

transporting means mounted to the door and extending downwardly of the door bottom to the floor for supporting the door on the floor and for enabling the door in its entirety to be moved into and out of the door opening, the transporting means comprising means for supporting the door disposed such that the door may be moved laterally to fit in the opening, the transporting means being positioned with respect to the door such that when the door is mounted in the door opening the transporting means is supported by the floor; and

second sealing means mounted to the door and extending downwardly of the door bottom to the floor to seal the bottom of the door opening.

2. The arrangement of claim 1 wherein the side and the top jambs and the door sides and tops have surfaces that are complemental and proximate to each other and wherein said first sealing means is mounted to one of said surfaces and bears against the other of said surfaces.

3. The arrangement of claim 2 wherein said first sealing means is mounted to a surface on each of the door sides and the door top.

4. The arrangement of claim 2 wherein at least one magnet is embedded in said first sealing means and said other of said surfaces is made of a magnetic material, said magnet and said magnetic material constituting said releasable retaining means.

5. The arrangement of claim 4 wherein said first sealing means is mounted to a surface on each of the door sides and the door top.

6. The arrangement of claim 1 wherein said door has an interior surface and an exterior surface and wherein said transporting means comprises:

at least three brackets mounted to said surfaces with at least two of said brackets mounted to one of said surfaces and the remainder of said brackets mounted to the other of said surfaces; and

a caster mounted to and depending from each bracket.

7. The arrangement of claim 6 wherein said second sealing means comprises:

a resilient strip mounted to one of said surfaces and depending therefrom against the floor, said strip being located closer to the surface on which it is mounted than the caster that is mounted on that surface.

8. The arrangement of claim 7 wherein the resilient strip is mounted to the interior surface and is bowed downwardly and away from the interior surface whereby static pressure in said chamber holds the strip against the floor.

9. The arrangement of claim 1 wherein said second sealing means comprises a resilient strip depending from the door against the floor.

10. The arrangement of claim 9 wherein the door has an interior surface and wherein the resilient strip is mounted to the interior surface and is bowed downwardly and away from the interior surface whereby static pressure in said chamber holds the strip against the floor.
