A vent enabling passage of air through a flexible cover such as those used to cover a boat, automobile, truck payload, stored materials at industrial sites, retail outlet outlets and the like. More specifically, the vent is of one piece unitary construction and includes an annular base secured to the flexible cover by adhesive or other conventional securing structure with the base including a central opening aligned with an opening in the flexible cover. The vent further includes a dome shaped louvered cover hingedly connected to the base and oriented in overlying relation to the base with the louvers enabling air passage through the cover and base for circulation of air in relation to the space covered by the flexible cover on which the vent is mounted. A retaining wall extends inwardly and upwardly from the base around the central opening to prevent water from entering the opening.
A vent for mounting on a panel having an opening therein, said vent comprising an base adapted to be mounted on said panel, said base including a vent opening for alignment with the opening in the panel, a cover mounted in overlying relation to the vent opening in the base, said base and cover being constructed of one piece construction, a hinge pivotally connecting a peripheral portion of the cover to a peripheral portion of the base, a locking structure interconnecting the base and cover for securing the cover in overlying relation to the base, said cover including at least one peripheral louver defining a slot opening to enable air flow through the cover, vent opening in the base and opening in the panel.
A louvered vent attached to an outer surface of a flexible panel adapted to cover and enclose a space occupied by items in which it is desired to provide ventilation through an opening in the cover, said vent comprising a base having an opening therein attached to the cover around the periphery of the opening in the cover, said base being adhesively mounted on the cover with the opening in the base in alignment with the opening in the cover, a closure member for the vent opening in the base, said closure member being hingedly connected to the base and lockingly retained in overlying closed relation to the vent opening in the base, said closure member being in the form of a dome shaped wall having a plurality of louvers in spaced relation to define slot openings for air flow through the vent, said louvers being staggered and overlapping in a manner to shed water while permitting air flow, said louvered vent being constructed of one piece plastic material.
