Abstract
Description
- The present invention relates generally to apparatus for ventilating buildings, and, more particularly, to roof vents and the like.
- Roof vents play a major role in maintaining the integrity of a building. In cold weather, roof ventilation maintains a cold roof temperature and thereby avoids ice damns created by melting snow. The ventilation also allows any moisture that enters the attic of the building to escape. In warm weather, roof ventilation helps to expel hot air from the attic to reduce the building's cooling load.
- Dormer vents are a common type of roof vent that are generally installed on the sloping portions of a roof system. As their name would suggest, dormer vents resemble building dormers, that is, windows that project vertically from a sloping roof. Nevertheless, despite their widespread usage, present versions of such dormer vents have several disadvantages. Because of their complex shapes, dormer vents are typically formed by joining several sections of material together. As a result, they may be difficult to manufacture. Moreover, the seams produced by the joined sections of material may produce weak spots that are susceptible to water leakage.
- For the foregoing reasons, there is a need for new roof vent designs that are easy to manufacture and avoid joined seams that can lead to water leakage.
- Embodiments of the present invention address the above-identified needs by providing improved roof vent designs.
- Aspects of the invention provide a roof vent comprising a first portion, a second portion, a third portion, and a fourth portion. The second portion is connected to the first portion. The third portion is connected to the second portion and defines one or more openings therein. The fourth portion is connected to the third portion. In a first region of the roof vent when the first portion and the third portion are resting on a horizontal surface, the second portion angles upward away from the first portion and the third portion angles downward towards, but does not contact, the first portion so as to create a gap in a bottom of the roof vent in gaseous communication with the one or more openings. In a second region of the roof vent, the second portion is substantially coplanar with the first portion, and a part of the second portion is pressed directly against a part of the third portion, which is pressed directly against a part of the fourth portion.
- Additional aspects of the invention provide a method for forming a roof vent. An assembly is formed comprising a first portion, a second portion, a third portion, and a fourth portion. The second portion is connected to the first portion. The third portion is connected to the second portion and defines one or more openings therein. The fourth portion is connected to the third portion. The assembly is processed such that, in a first region of the roof vent when the first portion and the third portion are resting on a horizontal surface, the second portion angles upward away from the first portion and the third portion angles downward towards, but does not contact, the first portion so as to create a gap in the bottom of the roof vent in gaseous communication with the one or more openings. The assembly is further processed such that, in a second region of the roof vent, the second portion is substantially coplanar with the first portion, and a part of the second portion is pressed directly against a part of the third portion, which is pressed directly against a part of the fourth portion.

FIG. 1A-1H show various views of aroof vent 100 in accordance with an illustrative embodiment of the invention. More particularly,FIG. 1A shows a plan view,FIG. 1B shows a front elevational view,FIG. 1C shows a rear elevational view,FIG. 1D shows a perspective sectional view cut along a plane indicated inFIG. 1B ,FIG. 1E shows a side sectional view cut along a plane indicated inFIG. 1B ,FIG. 1F shows a bottom perspective view,FIG. 1G shows a side perspective view, andFIG. 1H shows a top perspective view. - For ease of description, the
roof vent 100 may be conceptually separated into four portions. Afirst portion 105 is connected to asecond portion 110. Thesecond portion 110 is angularly connected to athird portion 115, which defines a plurality ofventilation slits 120 therein. Lastly, thethird portion 115 is angularly connected to afourth portion 125. The fourportions roof vent 100, in turn, take on different configurations when considered along the long axis of the roof vent 100 (i.e., the left-right axis inFIGS. 1A-1C ). With thefirst portion 105 and thefourth portion 125 of theroof vent 100 oriented horizontally in the manner shown in the figures, acenter region 130 of theroof vent 100 is characterized by thesecond portion 110 being angled upward away from thefirst portion 105, and thethird portion 115 being angled downward towards, but not in contact with, thefirst portion 105. This configuration provides agap 135 in the bottom of theroof vent 100 with thegap 135 in gaseous communication with the ventilation slits 120 in thethird portion 115. In contrast, inedge regions 140 along twoedges 145 of theroof vent 100, thesecond portion 110 is instead substantially coplanar (i.e., aligned) with thefirst portion 105 and a region of thesecond portion 110 is pressed directly against a region of thethird portion 115, which is pressed directly against a region of thefourth portion 125. This edge configuration is shown in a sectional view inFIG. 2 . Accordingly, adjacent to theedges 145, one finds fairly planar edge margins that run along the short axis of theroof vent 100. Between thecenter region 130 and theedge regions 140 of theroof vent 100, but closer to theedge regions 140, the fourportions - The
roof vent 100 may comprise a tool-malleable metal such as, but not limited to, aluminum, stainless steel, and copper. Notably, theentire roof vent 100 can be formed of a single piece of material that does not include any joined seams. For purposes of this invention, a “joined seam” is intended to encompass an interface defined by two previously-separate sections of material that are joined to one another by a means of fixation such as, but not limited to, gluing, nailing, screwing, clamping, welding, brazing, soldering, and riveting.FIG. 3 shows a flow diagram of a method for forming theroof vent 100 in accordance with an illustrative embodiment of the invention. In one or more embodiments, for example, a single sheet of aluminum may be cut to produce a flat rectangular piece (step 305). The flat rectangular piece may then be pressed to produce any desired surface features for the vent (e.g., surface ridges) and punched to produce the ventilation slits 120 (in this case louvered slits with integral slats) (step 310). Subsequently, the rectangular piece may then be folded so as to define thefirst portion 105, thesecond portion 110, thethird portion 115, and thefourth portion 125 in a configuration desired for thecenter region 130 of the roof vent 100 (step 315). Finally, margins along theedges 145 of thesecond portion 110 and thethird portion 115 may be pressed against thefourth portion 125 to produce the substantially planar edge regions 140 (step 320). Theresultant roof vent 100 may also be trimmed as desired and painted or otherwise coated with a surface protectant (step 325). -
FIG. 4 shows a perspective view of anunfinished roof vent 300 corresponding to theillustrative roof vent 100 afterstep 315, but just before one of its edges is pressed by a pneumatic metal press in accordance withstep 320. During pressing (step 320), apressing plate 405 pushes downward on the edge region of theroof vent 400. At the same time, afirst holding plate 410 presses the first portion of theroof vent 400 against a horizontal table 415 while asecond holding plate 420 presses the fourth portion of theroof vent 400 against the horizontal table 415. Finally, anangled piece 425 supports the third portion of theroof vent 400 inboard from the edge and, in combination with beveled edges on thesecond holding plate 420, allows theroof vent 400 to take on the desired shape during the pressing process. - Accordingly, while the design and function of the
roof vent 100 are entirely novel, embodiments of the invention may be produced utilizing conventional metal working techniques and metal forming tools that will be familiar to one having ordinary skill in the metal fabrication arts. Moreover, such metal fabrication techniques are described in a number of readily available publications, such as, for example, O.D. Lascoe, Handbook of Fabrication Processes, ASM International, 1988, which is hereby incorporated by reference herein. - The
roof vent 100, and, more generally, roof vents in accordance with aspects of the invention, may be installed on a sloping roof over a slit-shaped opening in that roof to provide a means of ventilation for an underlying building. Theroof vent 100 is preferably installed on a sloping roof such that thefirst portion 105 is positioned higher on the sloping roof than thefourth portion 125, while thegap 135 overlies the slit-shaped opening in the roof. During installation, thefirst portion 105 is preferably attached to the roof under the shingles. Thefourth portion 125 of theroof vent 100, in contrast, is preferably attached to the roof over the shingles. Fasteners, such as, but not limited to, nails or screws placed along the perimeter of theroof vent 100 may provide the actual means of fixation. - Once installed in this manner, the
roof vent 100 becomes what is commonly called a “dormer vent.” The positioning of thesecond portion 110 over the ventilation slits 120 creates a covering which inhibits precipitation from entering the ventilation slits 120 from above. At the same time, the louvered ventilation slits 120 further inhibit water from passing through theroof vent 100 into the underlying building as a result of precipitation being pushed sideways by wind. Perhaps most importantly, the lack of joined seams in theroof vent 100 substantially eliminates any weak points in theroof vent 100. Accordingly, the chance of leakage is substantially reduced when compared to those prior art roof vent designs that are not formed in this manner. - At the same time, roof vents in accordance with aspects of the invention, unlike many prior art roof vent designs, may be formed utilizing conventional metal forming techniques (e.g., cutting, stamping, bending, pressing) without the need to perform any metal joining processes (e.g., welding, brazing, soldering, riveting). The present roof vent designs are therefore also relatively easy and cost effective to manufacture.
- It should again be emphasized that the above-described embodiments of the invention are intended to be illustrative only. Other embodiments can use different types and arrangements of elements for implementing the described functionality. These numerous alternative embodiments within the scope of the appended claims will be apparent to one skilled in the art.
- It may, for example, in one or more alternative embodiments falling within the scope of the invention, be beneficial to install one or more reinforcement elements in the
roof vent 100.FIG. 5 shows a bottom perspective view of theroof vent 100 with reinforcingelements 500. In this particular illustrative, non-limiting embodiment, the reinforcingelements 500 comprise bent brackets (of, e.g., metal or plastic) that are periodically placed into the space between thesecond portion 110 and thethird portion 115. The reinforcingelements 500 may help to prevent theroof vent 100 from being crushed under heavy loads such as those that may be encountered when a roof is covered in snow. It is contemplated that the longer the roof vent, the greater number of such reinforcing elements that may be utilized. - All the features disclosed herein may be replaced by alternative features serving the same, equivalent, or similar purposes, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.
- Any element in a claim that does not explicitly state “means for” performing a specified function or “step for” performing a specified function is not to be interpreted as a “means for” or “step for” clause as specified in 35 U.S.C. §112, ¶6. In particular, the use of “step of” in the claims herein is not intended to invoke the provisions of 35 U.S.C. §112, ¶6.
