Abstract
A louver assembly for placement in an opening for regulating the inlet of air, comprising a first blade stack and second blade stack arranged in tandem, and a sill for supporting the first and second blade stack. The first and second blade stacks have a plurality of blades arranged in a horizontally-spaced and vertically-extending configuration defining a plurality of horizontally-spaced and vertical extending air passageways for the passage of air therethrough. The sill has a generally planar first portion for supporting the first blade stack and a sloped second portion for supporting the second blade stack, wherein the sloped portion and the second blade stack define therebetween a void for equalizing pressure within the assembly to facilitate the draining of water therefrom.
Claims16
A blade comprising:
- a lower edge;
- an upper edge;
- a leading edge;
- a tailing edge;
- a front tab;
- a rear tab;
- a blade body;
- a first vertically extending face;
- a second vertically extending face;
- an arcuate hook;
- an angled tab;
- and,
- an L shaped tab;
- wherein the leading edge is configured to face a first direction and the trailing edge is oriented facing an opposite second direction;
- wherein the leading edge is configured to define an edge of the front tab and the trailing edge is configured to define an edge of the rear tab;
- wherein a surface of the front tab opposite the leading edge changes from a first thickness to a second thickness defining a first transition zone from the front tab to the blade body;
- wherein the blade body maintains said second thickness from the front tab until it transitions back to the first thickness defining a second transition zone at a point on the rear tab opposite the trailing edge;
- wherein between the first and second transition zones the blade body is curved with an apex in the direction of the first vertically extending face;
- wherein the arcuate hook extends from the first vertical surface of the blade body starting from the side of the apex proximate to the tailing edge, extending over the apex with the hook opening facing first direction;
- wherein the second transition zone has the angled tab located on the first vertical surface;
- and,
- wherein the second vertically extending face has the L-shaped tab positioned proximate to the rear tab.
A louver assembly comprising:
- at least one blade;
- a first jamb member;
- a second jamb member;
- a head frame member;
- and,
- a sill;
- wherein the head frame member is configured to receive an upper edge of at least one blade;
- wherein the sill is configured to receive at least one lower edge of at least one blade;
- wherein the at least one blade is a plurality of blades configured to form a first stack and a second stack;
- wherein the sill is configured with a planar first portion and a sloped second portion extending from the planar first portion to a backsplash portion;
- and,
- wherein first bottom edges of the plurality of blades forming the first stack are received upon the planar first portion of the sill and wherein second bottom edges of the blades forming the second stack remain square cut in profile and are received and supported at an intersection of the sloped second portion and the backsplash portion.
A louver assembly for placement in an opening of a structure to regulate a passage of air and water therethrough, comprising:
- a first blade assembly including a plurality of vertically aligned louver blades;
- a second blade assembly including a plurality of vertically aligned louver blades;
- a frame assembly encompassing said first and said second blade assemblies, said frame assembly including a sill having a planar portion and an angled portion, said angled portion being coextensive with said planar portion and oriented at a predetermined angle with respect to said planar portion;
- wherein said plurality of vertically aligned blades of said first blade assembly rest upon said planar portion of said sill;
- and
- wherein said plurality of vertically aligned blades of said second blade assembly extend outwardly from said angled portion forming thereby an open void behind said first blade assembly and below said second blade assembly.
