Randall, Peoria, Ill.; said Randall assignor to said Smith Filed Apr. 12, 1965, Ser. No. 447,182 7 Claims. (til. 98-42) This invention relates to roof ventilators, and more particularly to ventilators of the type adapted to be mounted on and to extend along the exterior surface of the ridge of a roof to provide for the flow of air to and from the space in a building immediately below the roof.
One of the objects is to provide a roof ventilator for ridge mounting which has louvered vent openings in opposed side wall portions and wherein internal baffles are utilized to improve weather protection without unduly restricting air flow through the ventilator.
As another object, this invention has within its purview the provision of a roof ventilator having an internal baffle in spaced and opposed relationship to vent openings in the ventilator, which bafiie is integrally formed as a part of the ventilator structure.
Our invention further comprehends the provision of a roof ventilator structure wherein vent openings are provided in opposed downwardly and inwardly sloping side walls and baffles extend upwardly near the openings both internally and externally of the ventilator.
It is another object of this invention to provide a ventilator for mounting on a roof ridge and which has an internal baflle extending upwardly in spaced and opposed relationship to vent openings in a wall of the ventilator and wherein weep holes are provided between the said baffle and wall for the drainage of moisture from the interior of the ventilator.
This invention has for another object the provision of a ventilator adapted to be mounted on the ridge of a roof and wherein the ventilator walls, internal baflies and flashing elements are integrally formed from sheet material.
Other objects and advantages of the invention will be apparent from the following description and the accompanying drawings in which similar characters of reference indicate similar parts throughout the several views:
FIG. 1 is a fragmentary perspective view showing the application of a preferred embodiment of our roof ventilator to the ridge of a building roof;
FIG. 2 is a fragmentary perspective end sectional view drawn to a larger scale than FIG. 1 and showing details of the structure of the ventilator depicted in FIG. 1; and
FIGS. 3 and 4 are fragmentary end sectional views illustrating the adaptation of modified forms of our roof ventilators to the roofs of buildings.
In the exemplary embodiments of our invention which are shown in the accompanying drawings for illustrative purposes, roof ventilators (FIGS. 1 and 2), 12 (FIG. 3) and 13 (FIG. 4) are each shown as being mounted to extend along the ridge of a roof of a building 15. As is typical in building structure, the roof 14 has rafters 16 and 17 in spaced relationship longitudinal of the roof and sloping upwardly on opposite sides of the roof ridge and abutted together along the ridge. The rafters have roofing boards 18 secured to the top surfaces thereof. When ventilators of the type illustrated herein are to be used on a roof, a slot 19 is left between the roofing boards at the roof ridge to provide for the flow of air through the ventilator and to and from the interior of the building immediately beneath the roof. Roofing, such as shingles 20 covers the roofing boards from a position near the slot 19, so that the roof will shed water.
As shown in FIGS. 1 and 2, the ventilator 10 extends along the roof ridge and covers the slot 19. The ventilator disclosed is symmetrical in form and structure on opposite sides of a vertical longitudinal plane which passes through the roof ridge line. Although ventilators of the type disclosed herein may be made of various materials, the structures depicted are of a type suitable for manufacture from sheet metal, such as aluminum. It embodies a top cover part 22 which, in the present instance, is smoothly curved from side to side with the major portion of the mid-region thereof being generally arcuate. Side wall portions 23 and 24 are integral with the top cover part 22 and extend downwardly and inwardly from the opposite sides thereof, so that a generally acute angular relationship exists betweenthe side wall portions and adjacent parts of the top cover portion. Bafiles 25 and 26 are integrally formed along the inner edges of the side wall portions 23 and 24 by bending the sheet metal upwardly. The sheet material of the baflle, in the disclosed structure is return-bent along straight lines to provide top edges 27 and 28 on the baffles 25 and 26 at desired heights within the ventilator structure, and so that flashing portions 29 and 30 may be integrally formed with the rest of the ventilator parts to extend outwardly and downwardly from the bottoms of the baflies adjacent or near the inner edges of the side wall portions 23 and 24. The flashing portions 29 and 30 may be flexed or bent at the time of installation to match the pitch of the roof upon which the ventilator is installed. The spacing of the bafiles 27 and 28 from one another laterally of the ventilator desirably conforms to the width of the slot 19, so that when the ventilator is mounted over the slot the bafiies are in generally flush relationship to the edges of the roofing boards 18 which define the slot.
The side wall portions 23 and 24 have a multiplicity of vent holes 32 therein, which vent holes, in the disclosed structure, are each covered by a louver 33. The louvers, in the ventilator depicted in FIG. 2, are each integrally formed with one of the side wall portions, and each projects upwardly from its side wall portion into the ventilator structure and outwardly from the mid-region of the structure. Also as disclosed herein, the vent openings and louvers are arranged in rows extending laterally of the ventilator structure, and the rows are repeated in spaced relationship longitudinally of the ventilator.
Interiorally of the ventilator, the spacing between the top edges 27 and 28 of the bafiles 25 and 26 and the top cover portion 22 is sufficient to avoid restriction of air flow between the slot 19 and the vent openings 32. For maximum and most effective weather protection, the baffles 25 and 26 extend to a height within the ventilator which is above the height of the uppermost vent openings. As a general rule, changes of the direction of air fiow within the ventilator tend to reduce the moisture content of the air. This accounts for the disposition of the louvers 33 and the placement of the baflles within the ventilator structure illustrated in FIG. 2. The baffles 25 and 26 serve the purpose of preventing the flow of collected moisture within the ventilator to and through the slot 19. Weep holes 34 are provided at spaced positions along the side wall portions 23 and 24 adjacent the baffles 25 and 26 for the flow of moisture to the outside of the ventilator.
The top courses of shingles 20' on opposite sides of the slot 19 are placed sufiiciently close to the slot 19 to be overlapped by the flashing portions 29 and 30. The ventilator is secured to the roof by fastening means, such as nails 35 driven through the outer margins of the flashing portions and passing through the shingles 20 into the roofing boards 18.
If one cut length of the ventilator is not sufficient to extend the full length of the roof to which it is applied, one ormore additional lengths are butted together.
'Plugs (not shown) which fit snugly into the interior of the abutted ends and which are made of a relatively stiff flexible material are used to adjoin the ends. For additional protection sheet metal caps 36 which conform to the outer surface of the ventilator are placed over the ventilator to cover the abutted ends. Also, such plugs are utilized to close the ventilator at its opposite ends.
' In the modified forms of the ventilator shown in FIGS. 3. and 4, thetop cover portions 22a and 22b and the side wall portions 23a and 23b, 24a and 24b have section-a1 configurations such that together they have the general contour of a segment of a circular cylinder. As in the form illustrated in FIGS. 1 and 2, the ventilators of FIGS. 3 and 4 are symmetrical with respect to a central longitudinal plane extending along the roof ridge. The top cover portions'22a and 22b extend to positions at or below ahorizontal longitudinal plane passing through the center of curvature, so that the side wall portions 23a, 23b,
24a, and 24b each extend downwardly and inwardly therefrom. Like the structure of the ventilator of FIGS. 1 and 2, the side walls each have a multiplicity of vent holes 32a and 32b therein, which vent holes are each covered by louvers 33a and 33b. The vent holes 32a and 32b and the louvers 33a and 33b may be disposed in rows and the rows repeated at spaced intervals longitudinally of the ventilator.
In the ventilator shownin FIG. 3, the louvers 33a extend outwardly and downwardly relative to the respective side walls 23a and 24a of the ventilator. In the form shown in FIG. 4, the louvers 33b extend inwardly and downwardly with respect to their respective side walls 23b and 24b. The bafiies 25 and 26, the flashing portions 29 and 30 and the weep holes 34 of the ventilators shown in FIGS. 3 and 4 are like those illustrated and described with-respectto FIGS. 1 and 2 and have like relationships with other parts of the ventilators, so that it may be considered that parts bearing the same reference numerals are .alike and perform similar functions in each of the ventilator forms disclosed.
While each of the ventilators disclosed herein is adapted to effective use without any exterior baflles, the efliciency and weatherproofing of each may be improved by additionalexterior baflies 37 and 33 which extend upwardly from the outer edges of the flashing portions 29 and 30 at positions spaced laterally from the side extremities of the topcover portion and side wall portions of the ventilator.
The upward extending and outwardly projecting upper marginal portions 39 and 40 on each of the battles tends to deflect air upwardly and over the top of the ventilator, so that low pressure regions are formed on opposite sides of the ventilator adjacent the openings therein. The baflies 37 and 38 also have a tendency to reduce the amount of wind-driven rain or snow which is brought into direct contact with the louvers over the vent openings. While the baflles 37 and 38 which are disclosed herein may be'made as an integral part of the flashing portions 29. and 30, the baflles disclosed have bottom flange portions 42 and 43 respectively which underlie the outer margins of the flashing portions 29 and 30 and are secured in place by the nails which secure the venti later to the roof.
From the foregoing description and by reference to the accompanying drawings, it may be understood that the ventilators "herein disclosed are not only adapted to be integrally formed from strips of sheet material, but are also constructed and arranged to provide eflicient and effective ventilation with adequate weather protection. The relationship and placement of the internal batfles with respect to inwardly and downwardly sloping side portions is such that the baffles afford weather protection in addition to that provided by the louvers which extend over each vent opening. The internal baflles also function in directing the flow of moisture inside of the ventilator to the weep holes, through which such moisture passes to the exterior of the ventilator.
It is understood that the foregoing description is merely illustrative of the preferred embodiment of the invention and that the scope of the invention therefore is not to be limited thereto, but is to be determined by the appended claims.
