Abstract
Abstract An annular base having a central opening therein is provided for overlying and support from one side of a cover panel having a ventilation opening therein and with the base supported from the cover panel in at least reasonably good fluid tight sealed engagement with the portion of the cover panel extending about the opening. A cup-shaped cover is removably supported from the base and is somewhat resilient such that remote sidewalls of the cover may be inwardly deflected at the open end of the cover. Predetermined remote portions of the cover sidewall and corresponding remote portions of the base include coacting structure interlockingly engageable with each other upon return of the predetermined wall portions of the cover from inwardly deflected positions. The annular base defines an outstanding curb about the opening in the base and the closed end of the cover includes small ventilation openings therein and a central inwardly projecting stem from whose inner end a generally circular baffle is supported, the baffle being registered with the central opening in the base and of considerably larger plan area than that opening. Also, substantial portions of the periphery of the open end of the cover are spaced from the base to define air inlet slots and the base is provided with an adhesive coating on the side thereof remote from the cover for adhesive securement of the base to the cover panel from which the base is supported.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
299 words
A ventilator for a panel having a vent opening formed therethrough, said ventilator including a generally annular panel-like base for overlying and anchoring to one side of said panel, said base having a central opening therein and defining first and second remote sides with said first side of said base adapted to be mounted in at least reasonably good fluid tight sealed engagement with the portions of said panel extending about the vent opening formed in said panel, a cup-shaped cover defining a closed end, an open end and peripheral wall means extending about said closed end and between said closed end and said open end, said cover being constructed of a material rendering said cover shape retentive, but flexible and resilient to an extent that predetermined remote portions of said peripheral wall means, adjacent said open end, may be manually deflected inwardly and thereafter released for inherent return to non-inwardly deflected positions, said open end of said cover opposing and opening toward said second side of said base, said base and predetermined remote portions of said peripheral wall means including coacting anchor structure interlockingly engageable with each other upon return of said inwardly deflected portions of said wall means to their non-inwardly deflected positions, said cover including ventilation openings formed in said closed end, said coacting anchor structure including first radially outwardly projecting flanges carried by remote portions of said peripheral wall means adjacent said open end and second angle flanges carried by remote portions of said base and projecting outwardly from said second side and toward each other, said first flanges being removably captively receivable beneath said second flanges upon inward deflection of said remote portions of said peripheral wall means and subsequent release of said peripheral wall means remote portions for return to non-inwardly deflected positions.
Claim 2
Dependent Claim
299 words
A ventilator for a panel having a vent opening formed therethrough, said ventilator including a generally annular panel-like base for overlying and anchoring to one side of said panel, said base having a central opening therein and defining first and second remote sides with said first side of said base adapted to be mounted in at least reasonably good fluid tight sealed engagement with the portions of said panel extending about the vent opening formed in said panel, a cup-shaped cover defining a closed end, an open end and peripheral wall means extending about said closed end and between said closed end and said open end, said cover being constructed of a material rendering said cover shape retentive, but flexible and resilient to an extent that predetermined remote portions of said peripheral wall means, adjacent said open end, may be manually deflected inwardly and thereafter released for inherent return to non-inwardly deflected positions, said open end of said cover opposing and opening toward said second side of said base, said base and predetermined remote portions of said peripheral wall means including coacting anchor structure interlockingly engageable with each other upon return of said inwardly deflected portions of said wall means to their non-inwardly deflected positions, said cover including ventilation openings formed in said closed end, said coacting anchor structure including first radially outwardly projecting flanges carried by remote portions of said peripheral wall means adjacent said open end and second angle flanges carried by remote portions of said base and projecting outwardly from said second side and toward each other, said first flanges being removably captively receivable beneath said second flanges upon inward deflection of said remote portions of said peripheral wall means and subsequent release of said peripheral wall means remote portions for return to non-inwardly deflected positions.
Claim 3
Dependent Claim
25 words
The ventilator of claim 1 wherein said peripheral wall means is generally frusto-conical with the minor diameter end thereof being disposed adjacent said closed end.
Claim 4
Dependent Claim
35 words
The ventilator of claim 1 wherein said open end includes means supporting at least a majority of the periphery of said open end in slightly spaced relation relative to said second side of said base.
Claim 5
Dependent Claim
25 words
The ventilator of claim 4 including an outstanding peripheral flange extending about said central opening and projecting outwardly of said second side of said base.
Claim 6
Dependent Claim
25 words
The ventilator of claim 4 wherein said peripheral wall means is generally frusto-conical with the minor diameter end thereof being disposed adjacent said closed end.
Claim 7
Dependent Claim
41 words
The ventilator of claim 2 wherein said predetermined remote portions of said wall means include outwardly opening recesses formed therein to facilitate gripping of said predetermined remote portions of said peripheral wall means between the thumb and forefinger of a hand.
Claim 8
Dependent Claim
