Abstract: A vent assembly for mounting in a passageway extending through an exterior wall to provide ventilation to the space bounded by the exterior wall includes an apertured panel exteriorly juxtaposed with a security grate to prevent unauthorized intrusion through the exterior wall. Carriage bolts extend through the apertured panel and security grate into engagement with an anchoring element, such as a pair of L-shaped brackets disposed on opposed sides in the passageway. The smooth surfaced head of the carriage bolts, coupled with the square cross-section of the shank adjacent the head mating with square apertures in the apertured panel and in the security grate prevent turning of the carriage bolts from a location external to the exterior wall. Air through the passageway may be filtered with an air filter supported by bolts extending from the security grate.

Carriage bolts extend through the apertured panel and security grate into engagement with an anchoring element, such as brackets disposed in the passageway. In addition or in the alternative screws penetrably engaging the security grate may be attached directly to the exterior wall laterally of the passageway. The smooth surfaced head of the carriage bolts, coupled with the square cross-section of the shank adjacent the head mating with square apertures in the apertured panel and in the security grate prevent turning of the carriage bolts from a location external to the exterior wall. For further security, the louvered vent may be configured to overlap and shield the heads of the screws, if used.

Abstract: A security grate is disposed intermediate a conventional multi-apertured vent on the front of a garage door panel to prevent intrusion through the juxtaposed aperture in the panel. Straps or washers serving as a backing plate may be located on the interior of the panel to further hinder unwanted removal of the vent and the security grate from the panel to obtain access to the aperture in the panel. Alternatively, the security grate may be disposed adjacent the interior of the panel and then any backing plate variants may be omitted. A cover of insulating material is attachable adjacent the rear of the panel to prevent airflow through the panel aperture and to provide insulation. A transparent or translucent cover may be substituted for the insulating cover to provide illumination when the garage door is closed. A closeable opening may be provided in the cover to permit airflow therethrough on a selected basis.
