Abstract
A ventilator for a boat mooring cover or the like including a support plate on the underside of the cover and a cover plate on the outer side of the cover. The support plate and cover each include passages therein in fluid communication with each other and with an aperture provided in the cover. An extensible and retractible support is provided for adjustably positioning the ventilator at different levels. The support plate includes an annular groove while the cover plate includes an annular detent or clamping rib which cooperates with the groove in the support plate to pinch and displace a portion of the cover therebetween to attach the ventilator to the cover.

Ventilator apparatus for a flexible sheet, such as a boat covering, having a ventilation aperture through a portion of said sheet intermediate edge portions of said sheet, said covering having inner and outer sides, said apparatus comprising:
- cover means for covering said ventilation aperture, said cover means having at least one passage therein for communicating ambient air to said aperture;
- an inner support section for bearing against the inner side of said sheet, having at least one passage therein in fluid communication with said ventilation aperture and said first mentioned passage;
- means for coupling said cover means and said lower section together to clamp said cover means and said lower section to said outer and inner sides, respectively, of said sheet;
- one said cover means and said inner section including a projecting sheet clamping rib and the other of said cover means and said inner section including a recess for receiving said rib to clamp a portion of said sheet therebetween;
- and
- extensible and retractable support means coupled to said inner support section for supporting said ventilator apparatus at any selected one of a plurality of different levels to position the portion of said sheet adjacent said aperture at any selected one of a plurality of different levels relative to the edge portions of said sheet.
Ventilator apparatus for a flexible sheet, such as a boat covering, having a ventilation aperture through a portion of said sheet intermediate edge portions of said sheet, said covering having inner and outer sides, said apparatus comprising:
- cover means for covering said ventilation aperture, said cover means having at least one passage therein for communicating ambient air to said aperture;
- an inner support section on the inside of said sheet, having at least one passage therein in fluid communication with said ventilation aperture and said first mentioned passage;
- means coupling said cover means and said lower section to secure said cover means and said lower section to said outer and inner sides of said sheet;
- said cover means and said inner section including cooperating detent and detent receiving means for clamping to opposite sides of said sheet;
- said cover means comprising a first annular plate, having an opening therethrough, in alignment with said aperture;
- said detent receiving means comprising an annular recess in said first plate;

In combination with a flexible sheet having upper and lower sides and a ventilation aperture therethrough, and means for securing edge portions of said sheet to an object such as a boat or the like, comprising:
- ventilator apparatus having at least one passage therein for communicating ambient air to said aperture, including:
- means on the upper side of said sheet for covering said aperture;
- and
- extensible and retractable support means on said object for supporting said ventilation apparatus at any selected one of a plurality of different levels to position the midportion of said sheet at any selected one of a plurality of different levels above the adjacent sheet portions;
- said covering means comprising:
- a first annular plate having an opening therein aligned with said aperture;
- a cover plate overlying said first annular plate;
- and
- spacer means mounting said cover plate in vertically spaced relation with said annular plate;
- said passage being provided in said spacer means;
- said ventilator apparatus further including:
- a lower section comprising:
- a second annular plate abutting the underside of said sheet and including an opening therethrough aligned with said aperture;
- and
- means coupling said first and second annular plates together to sandwich a portion of said sheet adjacent said aperture therebetween;
- one of said covering means and said lower section including detent means and the other of said covering means and said lower sections including detent receiving means for receiving said detent means to properly align said covering means relative to said lower section;
- one of said annular plates including sheet pinching projecting rib means for displacing a section of the sheet, and the other of said annular plates including a complimentally formed recess for receiving the displaced section of said sheet and said rib means.
