Abstract

A vent cover for covering an opening in a building structure to vent its interior is provided. The vent cover includes a hollow cover member with an open bottom for positioning over and covering the opening in the building and a front end with an opening. A grill is removably secured in the opening in the front end of the cover member. The grill has a plurality of partitions. Each of the partitions is defined by intersecting members, which have a tapered cross section for accelerating the flow of air through the grill. The grill also has a splash guard and an overhang structure optimal for preventing rain, snow and water from entering the grill and the opening in the building structure. The cover member may be aerodynamically shaped for use atop vehicles such as trailers and RVs.

First claim

What is claimed is:

1. A vent cover for covering an opening extending through a roof or wall structure for venting, the vent cover comprising:
a hollow cover member with an open bottom for covering the opening extending through the roof or wall structure, and a grill opening, said hollow cover member having at least one channel and further comprising at least one of tabs or holes; and
a grill removably secured in the grill opening in the cover member, said grill comprising an upper vent portion and a bottom splash guard comprising legs disposed below said upper vent portion and said upper vent portion angled relative to said splash guard to overhang said splash guard, at least one of said legs configured to be positioned in said at least one channel, said grill further comprising the other of tabs or holes for engagement with said hollow cover member;
wherein said grill having a plurality of partitions, each of said partitions being defined by integrally formed intersecting members wherein air passes over two surfaces of said intersecting members, said intersecting members each having rounded leading edge and a tapered cross section for accelerating the flow of air through the grill.

2. A vent cover according to claim 1 , wherein the partitions are formed in said upper vent portion of the grill, said upper vent portion extending upwardly from the bottom splash guard and outwardly toward a front end of the cover member so that the upper vent portion of the grill overhangs the splash guard.

3. A vent cover according to claim 1 , wherein the upper vent portion of the grill includes a top, a front end of the cover member extends outwardly beyond said top so that the grill opening of the cover member overhangs said grill.

4. A vent cover for covering an opening extending through the roof or wall for venting an interior, the vent cover comprising:
a hollow cover member with an open bottom for covering the opening through the roof or wall, and a grill opening, a pair of channels defined by protruding portions; and
a grill removably secured in the grill opening of the cover member, said grill comprising a leg disposed in each of said channels, said grill having one of a tab and a hole and said hollow grill cover having the other of a tab or a hole to releasably connect said grill to said hollow cover member;
wherein said grill has a plurality of partitions, each of said partitions being defined by integrally formed intersecting members, said intersecting members each having a cross section comprising a thick rounded leading edge and a thin trailing end for accelerating the flow of air through the grill, a splash guard disposed below an upper vent portion of said grill at an angle to said upper vent portion such that said upper vent portion overhangs said splash guard, said grill being oriented in the grill opening of the cover member in a direction wherein the rounded leading edge of the intersecting members faces an inner surface of the cover member.

5. A vent cover according to claim 4 , wherein the grill has a bottom splash guard, and the partitions are formed in said upper vent portion of the grill, said upper vent portion extending upwardly from the bottom splash guard and outwardly toward the front end of the cover member so that the vent portion of the grill overhangs the splash guard.

6. A vent cover according to claim 4 , wherein the upper vent portion of the grill includes a top, said front end of the cover member extends outwardly beyond said top so that the grill opening in the cover member overhangs said grill.
