Abstract
A sealing grommet, particularly for data centers and the like, formed of one or a pair of U-shaped frame sections, each co-molded with a thermoplastic elastomeric seal of corrugated wave form, with corrugated edges of the seals exposed at the open sides of the U-shaped frames. A pair of such grommet sections joined together, with the corrugated edges arranged to be in contact and in phase, provides a uniquely efficient seal to hold back air under pressure while allowing various pass-through elements, such as cables, hoses, etc., to be extended through the grommet and while enabling the pass-through elements to be easily added, removed, or rearranged as may be necessary to accommodate the dynamic changes experienced in the operation of a data center.
Claims64
A kit for a sealing grommet, the kit comprising:
- (a) first and second grommet parts;
- (b) each grommet part having a frame and having a sealing member connected to the frame, the sealing member forming an air barrier and having a resiliently flexible web-like corrugated portion formed of elastomeric material;
- (c) the corrugated portion having a set of corrugations, having a base portion, and having a corrugated free end edge portion opposite the base portion;
- (d) the corrugated free end edge portion being resiliently displaceable toward the base portion;
- and
- (e) the first and second grommet parts being adapted to be positioned with the corrugated free end edge portions of the respective corrugated portions thereof in a closely abutting relationship along a sealing line and with the free end edges of the set of corrugations of the first and second grommet parts being aligned in phase such that, in the absence of displacement of the corrugated free end edge portions by a pass-through object, the corrugated free end edge portion of the first sealing member follows and closely abuts the corrugated free end edge portion of the second sealing member along a full length of the sealing line.
