Abstract
Abstract A louver assembly that includes a rectangular frame. Vertically spaced louver blades span side members of the frame. A gutter member overlies the louver blades and underlies an upper member of the frame. The gutter member includes an outer wall panel having an upper edge terminating beneath an outer face of the upper member to define a transverse water inlet opening receiving rain water from the upper member and from a wall thereabove. Downspout means in one of the side frames receives water from the gutter member. Water from the louver blades is also received in one of the side frames but the water from the gutter member is isolated from the louver blades.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
136 words
A louver assembly which comprises a frame including a transverse upper member, upright side members, and a transverse lower member, a plurality of vertically spaced louver blades spanning the side members, a gutter member overlying the louver blades and underlying the upper member, the gutter member including an outer wall panel having an upper edge terminating beneath an outer face of the upper member to define a transverse water inlet opening receiving rain water from the transverse upper member, enclosed downspout means in one of the side members receiving water from the gutter member and conducting the water from the gutter member past the louver blades, and means in one of the side members for receiving water from the louver blades, the downspout means being isolated from the means for receiving water from the louver blades.
Claim 2
Dependent Claim
136 words
A louver assembly which comprises a frame including a transverse upper member, upright side members, and a transverse lower member, a plurality of vertically spaced louver blades spanning the side members, a gutter member overlying the louver blades and underlying the upper member, the gutter member including an outer wall panel having an upper edge terminating beneath an outer face of the upper member to define a transverse water inlet opening receiving rain water from the transverse upper member, enclosed downspout means in one of the side members receiving water from the gutter member and conducting the water from the gutter member past the louver blades, and means in one of the side members for receiving water from the louver blades, the downspout means being isolated from the means for receiving water from the louver blades.
Claim 3
Dependent Claim
79 words
A louver assembly as in claim 1 in which the frame includes an outer side and an inner side, the louver blades extend upwardly and inwardly from outer edges thereof and the gutter member includes an inner wall spaced from the outer wall and spaced from the inner side of the frame and attached to the transverse upper member and extending downwardly therefrom, the gutter member overlying only a lower portion of an uppermost one of the louver blades.
Claim 4
Dependent Claim
68 words
A louver assembly as in claim 1 in which the transverse lower member includes a transverse plate portion and an inner wall portion extending upwardly therefrom, the downspout means and the means for receiving water from the louver blades discharging the water onto the transverse plate portion, there being an opening beneath a lowermost one of the louver blades for receiving the water from the transverse plate portion.
Claim 5
Dependent Claim
65 words
A louver assembly as in claim 1 in which each louver blade includes an outer main portion extending upwardly and inwardly from a lower edge at a small acute angle to the horizontal and an inner main portion extending upwardly and inwardly to an inner edge at a large acute angle to cause entering air to change direction while flowing inwardly between the louver blades.
Claim 6
Dependent Claim
26 words
A louver assembly as in claim 4 in which the small acute angle is approximately 24 degrees and the large acute angle is approximately 48 degrees.
Claim 7
Dependent Claim
