Thermal release of a self-opening cover

摘要

A cover is fitted to an aperture in an enclosure. A biasing mechanism is connected to the cover to mechanically bias the cover in an open position. An adhesive member is disposed around the aperture to retain the cover in a closed position against the bias of the biasing mechanism. A release mechanism effects release of the cover from the adhesive member by diminishing adhesion thereof in response to an open command signal.

主权项

1. A cover apparatus for an enclosure comprising:
a cover to extend over an aperture in the enclosure when in a closed position and to expose the aperture when in an open position; a biasing mechanism connected to the cover to mechanically bias the cover in the open position, wherein the cover and the biasing mechanism are constructed from identical material and in unitary formation such that the cover coils upon itself in the open position and is uncoiled in the closed position over the aperture in the enclosure; an adhesive member disposed around the aperture to retain the cover in the closed position against the bias of the biasing mechanism; and a release mechanism to effect release of the cover from the adhesive member by diminishing adhesion thereof in response to an open command signal.
