Abstract
Abstract The covering device consists in an aerated grate comprising tabs AL with an automatic and manually controlled rotation angle according to the intensity of rain and/or snow or wind. Tabs AL have a semitubular base profile 1, a baffle plate 2, a dripping plane 3, a vertical wall or plane 4, and a plurality of intermediate planes 5 with upper portions 5A, having bounce-preventing and gutter functions to collect rain in a double gutter frame 7, which rain water is then led into a reservoir 21 which will, due to the increasing weight thereof, lift a counterweight 9 to cause the automatic closing of tabs AL. Alternatively, the tabs may be closed by operating manual lever 16 or by means of a wind operated automatism having an aerodynamic plane 27 being provided with a limit stop rotation angle to allow it to recede from the wind.

Total Claims: 9
Claim 1
Independent Claim
236 words
An automatically controlled aerated grate covering device for the sheltering from sun and rain, said grate covering device also being adapted for manual control thereover, said device comprising: a plurality of tabs arranged in equispaced planes, each of said tabs including a semitubular base, a baffle plate connected to said base and extending tangentially therefrom, a plurality of intermediate plates attached to said baffle plate in spaced-apart relationship, a wall connected to said base and extending outwardly therefrom, and a dripping plate attached to the free end of said baffle plate; a gutter frame having a corresponding plurality of holes, said tabs being rotatably received within said holes; a coupling bar having two ends, said bar connecting said tabs and extending transversely thereof for simultaneously rotating said tabs, each of said tabs having a pivot pin located near the attachment of said dripping plate to said baffle plate, said pin being engaged by said coupling bar to connect said tabs; a reservoir having a fluid intake and fluid outlet, said reservoir being slidably received within a duct; conduit means for conducting fluid from said gutter frame to said fluid intake of said reservoir; first connecting means connecting said reservoir to one end of said coupling bar, said first connecting means including a rod pivotally connected to a lever; a movable counterweight; and second connecting means connecting said counterweight to the other end of said coupling bar.
Claim 2
Dependent Claim
236 words
An automatically controlled aerated grate covering device for the sheltering from sun and rain, said grate covering device also being adapted for manual control thereover, said device comprising: a plurality of tabs arranged in equispaced planes, each of said tabs including a semitubular base, a baffle plate connected to said base and extending tangentially therefrom, a plurality of intermediate plates attached to said baffle plate in spaced-apart relationship, a wall connected to said base and extending outwardly therefrom, and a dripping plate attached to the free end of said baffle plate; a gutter frame having a corresponding plurality of holes, said tabs being rotatably received within said holes; a coupling bar having two ends, said bar connecting said tabs and extending transversely thereof for simultaneously rotating said tabs, each of said tabs having a pivot pin located near the attachment of said dripping plate to said baffle plate, said pin being engaged by said coupling bar to connect said tabs; a reservoir having a fluid intake and fluid outlet, said reservoir being slidably received within a duct; conduit means for conducting fluid from said gutter frame to said fluid intake of said reservoir; first connecting means connecting said reservoir to one end of said coupling bar, said first connecting means including a rod pivotally connected to a lever; a movable counterweight; and second connecting means connecting said counterweight to the other end of said coupling bar.
Claim 3
Dependent Claim
38 words
An aerated grate covering device as claimed in claim 1 further comprising a manually operable lever, connected to said frame, for positioning said tabs on said frame, said lever providing said manual control over said grate covering device.
Claim 4
Dependent Claim
26 words
An aerated grate covering device as claimed in claim 1, wherein the number of the intermediate plates is related to the height of said baffle plate.
Claim 5
Dependent Claim
46 words
An aerated grate covering device as claimed in claim 1, further comprising a bushing disposed within each of said semitubular bases of said tabs, each of said bushings including a central shim adjusting ring nut, whereby said nut functions as a dripper for said semitubular bases.
Claim 6
Dependent Claim
30 words
An aerated grate covering device as claimed in claim 1 wherein said gutter frame comprises a double gutter frame having a central wall for supporting each of said semitubular bases.
Claim 7
Dependent Claim
26 words
An aerated grate covering device as claimed in claim 1 wherein said first and second connecting means further comprise tension rods connected to said coupling bar.
Claim 8
Dependent Claim
65 words
An aerated grate covering device as claimed in claim 1 further comprising means for automatically operating said device in response to strong winds, said wind responsive means including a support rotatably connected to said frame and said manually operable lever means, an aerodynamic plate pivotably carried on said support and a cable for connecting said aerodynamic plate to said manually operable lever and said frame.
Claim 9
Dependent Claim
46 words
An aerated grate covering device as claimed in claim 7 wherein said aerodynamic plate is in a first plane, said wind responsive means further comprising a plate in a second plane perpendicular to said first plane, said aerodynamic plate being pivotably mounted to said perpendicular plate.
