The invention herein disclosed and claimed relates to anchors for roof ridges. Such anchors are installed so that they support roof ridge tiles and provide anchorages for the upper row of roof tiles on roof sections between the ridges and the eaves.
The general construction of roof ridge anchors includes an upper part sometimes known as the crown or head over which the typical roof ridge tile lies. The roof ridge tiles are usually secured in some manner to the roof ridge anchor. Those tiles are typically shaped, as seen in cross-section, as having inverted U-shaped openings which are placed over the roof ridge anchor with the sides of that inverted U diverging from the vertical centerline of that U. Thus the crown or head of the roof ridge anchor is located within that inverted U-shaped opening. Roof ridge anchors also typically have main body portions extending downwardly from the crown and nailer or securing flanges on the bottoms of the main body portions which conform with the slopes of the roof on opposite sides of the roof ridge itself, and provide a means for securing the roof ridge anchor to the roof. The background of the invention also includes many patents which are classified in Classes 52 and 454. Examples of these U.S. patents are U.S. Pat. No. 2,508,032—Kennedy; U.S. Pat. No. 3,481,263—Belden; U.S. Pat. No. 4,325,290—Wolfert; U.S. Pat. No. 4,413,458—Ting; U.S. Pat. No. 4,558,637—Mason; U.S. Pat. No. 5,766,071—Kirkwood; U.S. Pat. No. 6,286,273—Villela et al; U.S. Pat. No. 6,308,472—Coulton et al; U.S. Pat. No. 6,378,256—Gembala; U.S. Pat. No. 6,381,916—Maisch et al; and U.S. Pat. No. 6,647,675—Castellanos.
In it broadest sense the invention is that of a linearly extending roof ridge anchor having a body section, a crown section and a nailer section, the crown section and a part of said body section being adapted to have one or more roof ridge tiles received thereover and thus being adapted to be secured to the roof ridge anchor crown section and to be engaged by the engagement lines or surfaces areas so that any stresses at these engagement lines or areas are either diminished or eliminated. The nailer section of the roof ridge anchor extends outwardly and downwardly from the body section and is adapted to secure the roof ridge anchor to portions of a roof extending outwardly and downwardly from the opposite sides of a roof ridge on which the roof ridge anchor is adapted to be installed.
It is old in the art to provide a roof ridge anchor having a flat crown top surface and the main body being flat side surfaces which are edge-secured to the flat crown top surface and thus form two substantially right-angled edges extending linearly of the roof ridge anchor and these two edges are the only support contacts between the roof ridge tiles and the crown of the roof ridge anchor. One modification of this has been to have the entire flat crown top surface shaped in cross-section as a V. There have been problems of water retention and leakage in these V-shaped crown top surfaces, particularly when tile attachments include nails or screws, extending downwardly through the highest point of the rooftiles and thus into the bottom of the V thus making it much more receptive to water leakage into the interior of the roof ridge anchor and thus to the ridge of the roof that is supposed to be protected from water, following the path of the nails or screws. At times a glue-like mastic material is placed in the V, usually at intervals, to hold the tiles in place, forming a series of water retention points which makes it way through the pierced bottom of the V to the roof ridge that should be protected.
It is one of the features of the invention that such water retention is minimized in any of several manners, none of which do so by making the entire top surface of the crown as an inverted V. Even if a trough is provided in a part of the crown flat surface, it does not have its lower terminus at the point of a V where a nail or screw used to hold the ridge tiles in place would penetrate the crown top surface and any water retained would eventually leak therethrough.
One of the improvements embodied in the invention is the provision of any of several roof ridge head or crown sections having shapes in cross-section which are adapted to closely receive the roof ridge tiles thereover and which at times may be engaged either at more than two linear engagement edges or may be engaged at substantial surface areas of engagement of the roof ridge tiles with the roof ridge anchor crown section, thus lessening or entirely eliminating the linear type edge-supporting stresses on the tiles by providing a greater number of edge-like supports while at least maintaining, and in several instances improving, the roof ridge anchor's ability to support the roof ridge tiles without any adverse deformations of the roof ridge anchor, even though at times some heavy loads may be exerted on the roof ridge tiles ant thus possibly on the roof ridge anchor. This can possibly occur if heavy branches hit or fall on some roof ridge tiles, or someone steps on the roof ridge tiles while they are in place on the roof ridge anchor. This is accomplished with the provision of several different cross-section shapes of roof ridge anchor crowns by providing roof ridge anchors having several different crown section cross-section shapes, defined by surfaces of sheet metal material including a crown top surface and beveled crown side surfaces and usually the upper parts of said body section which may be considered to be a part of the crown as well as larger surfaces for such engagement by roof ridge tiles at times.
It is to be understood that, while describing the roof ridge anchors embodying the invention in further detail, and in some of the claims, the anchors herein shown, described and claimed may be identified as being made of sheet metal material, non-metallic materials which have the strength to perform the same functions and to last for at least the usual period of a roof having such roof ridge anchors installed and tiles thereon, may also be used. At this time, however, it is economically more feasible to make the roof ridge anchors out of sheet metal.
It a similar broader sense the invention is that of a linearly extending roof ridge anchor, sometimes known in the art as a ridge cap, comprising a length of metallic material having a first surface area forming a roof ridge anchor top surface. It has second and third surface areas which are spaced laterally apart and are generally perpendicular to and spaced from the first surface area. The second and third surface areas respectively include first and second roof ridge anchor side surfaces with at least major area portions thereof respectively being parts of the second and third surface areas. It also has fourth and fifth surface areas which are intermediate connecting surface areas so that they are not substantially planar continuations of either of the first and second or either of the first and third surface areas. The fourth surface area operatively connects the first surface area with the second surface area. The fifth surface area operatively connects the first surface area with the third surface area. The first, fourth and fifth surface areas combine so as to provide a ridge anchor crown section which more nearly conforms to the interior surface of a typical roof ridge tile than would be the case when the first surface area would be directly connected to the second and third surface areas without using the fourth and fifth surface areas. Each of the first and second roof ridge anchor side surfaces has a ridge anchor mounting flange formed so as to extend outwardly of the roofridge anchor at angles that are adapted to permit the roof ridge anchor to accommodate the slopes of a roof extending outwardly and downwardly from a roofridge on which the roof ridge anchor may be installed.
In a more specific sense, the invention also lies in the arrangement of a linearly extending roof ridge anchor comprising a length of metallic material formed to have the following features: a first plane having a roof ridge anchor top surface with at least major area portions thereof being in the first plane; second and third planes which are spaced laterally apart and are generally perpendicular to the first plane, the second and third planes respectively having first and second roof ridge anchor side surfaces with at least major area portions thereof respectively being in the second and third planes; fourth and fifth planes which are intermediate connecting planes, the fourth plane operatively connecting the first plane with the second plane and the fifth plane operatively connecting the first plane with the third plane; with the first and fourth and fifth planes cooperatively providing a ridge anchor crown section which more nearly conforms to the interior surface of a typical roof ridge tile than would be the case when the first plane is directly connected to the second and third planes at approximately right angles or more. The first and second roof ridge anchor side surfaces have ridge anchor mounting flanges formed so as to extend outwardly of said roof ridge anchor at angles that are adapted to permit said roof ridge anchor to accommodate the slopes of a roof extending outwardly and downwardly from a roof ridge on which the roof ridge anchor may be installed.
One of the several specific species of the roof ridge anchor embodying the invention has the first surface area being as least predominantly a flat surface area. Another specific species of the roof ridge anchor embodying the invention has the first surface area being curvilinear in cross-section. In other modifications, the first surface area is curvilinear in cross-section, and that arrangement may be utilized either with flat side surfaces or with the side surfaces being either partially or wholly curvilinear as seen in cross-section of the roof ridge anchor. In similar manner, one of the other modification features is that the fourth and fifth surface areas may be curvilinear as seen in cross-section, with the first surface are being either flat or curvilinear as previously described. In still other closely-related modifications the fourth and fifth surface areas may each be formed of upper and lower parts which are in planes that are joined together at relatively small angles so that the fourth and fifth surface areas are slightly out of planar alignment, and thus appear in cross-section to be somewhat indented. The slight indentations so formed may be used for securing material such as a mastic or a glue to be placed therein on the outer surfaces thereof and also engaging the inner surfaces of the ridge tile or cap. When the mastic or glue is provided in linearly spaced relation within the indentations, the spaces between the mastic or glue are able to permit flow of any water that might come through the ridge tile opening through which securing devices such as nails may be inserted to more solidly anchor the ridge tiles in place, that water flow simply continuing to flow through these spaces because the slopes of both parts of the fourth and fifth surface areas are still outward and downward and the water flow follows that surface path and is harmlessly deposited on the tile which overlies the earlier noted roofridge anchor mounting flanges, and down off the roof. This has very distinct advantages over some prior constructions where the at least substantially entire top surface area is formed as a V. Any water which leaks past the nails or similar securing devices to the interior of the roof tile simply is trapped in the V, tending to cause the roof ridge anchor to deteriorate at a faster rate than it would if there were no place where the water could be collected.
In other modifications of the invention, the top surface area may be curvilinear so that it is adapted to more closely conform to the interior surfaces of the ridge tiles when they are installed. This curvilinear form may be seen as an arc of a circle when viewed in cross-section, of may be somewhat elongated so that the radii of the curvilinear area become greater and greater as that area approaches the side surface areas. Either of the curvilinear arrangements may have similar slight exterior indentations as earlier described.
The top of the crown portion of the roof ridge anchor may be formed in cross-section in the form of a “S” on each half with the lower parts of the area where the two “S's” are formed providing a large trough. This permits a rather large amount of fastening mastic or glue to be used to attach the ridge tile to the anchor, and there is no leakage within the ridge tile or within the roof anchor assembly. By filling the trough completely with the mastic or its equivalent, there is no water allowed to be trapped in the trough. Also, there can be some mastic retention advantage in using a groove that is trapezoidal in cross-section, with the smaller side of the trapezoid being the side that is open to the space immediately above the upper surface of the crown.
It is within the purview of the invention that when such arrangements for the slight exterior indentations are used, they may be linearly spaced along the linear length of the roof ridge anchor, thus still serving to assure that water is not trapped and the portions between the indentations that are not indented may still either approach or make actual contact where the full curvilinear surfaces exist. This will provide adequate water removal as well as a more desirable area of engagement for the ridge tile engagement with the ridge roof anchor should such engagement occur.
There may be occasions when it is desired to have the flat top surface to also have a small trough extending linearly of the roof ridge anchor, and yet want to absolutely prevent any water drip on the interior of the roof ridge anchor, such as when it leaks past a securing device such as a nail or screw. This arrangement is accommodated by one of the variations of the roof ridge anchor assembly. One example is shown in the drawings in which a substantially semi-circular cross-section trough is provided in the top surface area, and the side surfaces are provided with linearly extending tab-receiving bosses or recesses or openings formed from and as part of the side surfaces. Such bosses extend angularly downward and outward and having drain openings in their outer end lower areas to receive tabs formed on a curvilinear-in-cross-section water shield strip. There is only one such tab needed on each water shield strip side. These tabs are, formed to extend downwardly and outwardly, preferably by the curvilinear shape seen in cross-section or of somewhat different angle of extension so that they substantially match and therefore are mateable with the interiors of the bosses of the side surfaces. These tabs formed on either side of the water shield and also extend the linear length of the anchor assemble as do the recesses formed by the interiors of the bosses of the side surfaces. The water shield strip can be inserted through the lower end of the main body of the roofridge anchor until its outwardly extending tabs engage and enter the interior recesses of the bosses, retaining the water shield in place and still extending downwardly and outwardly. As seen in cross-section in the drawing, the water shield has its center section extending upwardly so that any water impinging upon it from any nail or screw hole in the bottom of the trough simply flows outwardly and over the water shield tabs so that it exits the ridge roof anchor through the drain holes provided in the recesses.
Instead of forming full boss recesses, tabs may be struck outwardly of the side surfaces of the roof ridge anchor assembly so that they are extending downwardly as well, leaving openings for drainage. These tabs are located in precise linearly spaced relation, and the water shield is provided with matching tabs so that when the water shield is pushed upwardly into the main body of the roof ridge anchor, the shield tabs will snap into the openings made by the tabs of the side surfaces, holding the water shield and also providing surfaces for the outward flow of any water that might impinge on the upper outer surface of the water shield, substantially as in the earlier-described tabs and recesses arrangement.
Still another modification of the species wherein the possible water leakage is directed out of the main body of the roof ridge anchor is shown. In that one, the upper portions of the side surfaces are bent first inwardly and then reverse bent outwardly so that they have a downward and outward slope, and then are then reversely bent inwardly to form troughs on the outer edges of the inner surfaces before continuing upwardly to form the crown portion of the roof ridge anchor. This arrangement also has the small linearly extending depressions earlier described, which will initially collect any water leaking, and deliver it through weep holes in the bottoms of these depressions so that the water impinges on the upper surfaces of the reversely bent sections and flows outwardly to another set of weep holes which open to the exterior of the entire roof ridge anchor body.
Another very similar arrangement is illustrated in the drawing where the top of the crown of the roof ridge anchor is flat and is also formed to provide, as seen in cross-section, a water path to the outer side of the roof ridge anchor. The two side surfaces are very close together from the crown to the point where the anchor flanges are provided. They are preferably offset laterally and have a waterproof filling between them preventing any of the water from entering the lower part of the anchor assembly.
If in any of these modifications having those slight exterior indentations fit closely to the interior surfaces of the tile, and particularly the lower part of the indentation wall, so that the flow of water may be impeded and it would then be retained at least part way along the length thereof, a slight long indentation may be made in the wall of the curvilinear part of the fourth and fifth curvilinear surfaces which extends downwardly and allows the water to flow through it to the exterior of the roof ridge anchor. This arrangement is particularly appropriate when the outer surface of the entire crown area of the roof ridge anchor is a close fit with the interior surface of the ridge tile that fits over it. It is not a requirement of the invention that the roof ridge tiles in any installation using a roof ridge anchor embodying the invention herein disclosed and claimed actually touch any part of the roof ridge anchor, although such touching does occur or is very closely approached with many installations. It is well known that in some installations the roof ridge tiles are in engagement with and supported by the top rows of roof tiles on either side instead of by a part of the roof ridge anchor. Even so, it is still important to keep water from leaking into the roof ridge anchor interior should there be any chance or opportunity that it could do so.
It is also desirable to make any of the roof ridge anchors from Galvalume, which is a highly rust resistant combination of steel and aluminum and other ingredients. This gives the roof ridge anchors a much longer life than those made out of steel, even when is coated with zinc and thus galvanized. It is also stronger than ordinary aluminum which is used at times in the manufacture of roof ridge anchors. While this forms no part of the invention since some roof anchors have been made of this material before the invention herein disclosed and claimed, it is considered sufficiently important to emphasize its advantages.

The roof ridge anchor 30 shown in
Anchor 30 has several planar sheet metal surfaces which extend longitudinally for the length of an anchor. Anchors are usually made in any of several specified lengths. One of the common lengths is 10 feet. The particular length is not so much a function of the capabilities of the machines used to bend and otherwise shape the sheet metal members as it is the desires of the customer and the ease of storing, moving and transporting a group of anchors.
More specifically, anchor 30 has three major parts, which are the anchor head section or crown 32, the anchor body section 34 and the nailer section 36. The anchor head section 32 is made of a cover section which is made of the three planar surfaces 38, 40 and 42. These three planar surfaces are, respectively, the center cover portion 38 having a plane 39 and the two angularly disposed portions 40 and 42 respectively having planes 41 and 43. Portions 40 and 42 are formed from the sheet metal member by bending portions 40 and 42 at bend lines 44 and 46 located where those two portions are connected by their edges. The plane 41 of the angularly disposed portion 40 results when that portion is bent about 45° along the bend line 44. Similarly, the plane 43 of the angularly disposed portion 42 results when that portion is bent about 45° along the bend line 46. The anchor body section 34 includes the two angularly disposed side surfaces 48 and 50, respectively being in the planes 49 and 51. Side surfaces 48 and 50 formed by bending the material of the anchor 30 along bend lines 52 and 54 so that they are angularly disposed relative to angularly disposed portions 40 and 42. The planes 41 and 43 of the angularly disposed portions 40 and 42 are positioned at about 45° from the plane 39 of the center cover portion 38, and the planes 49 and 51 of the side surfaces 48 and 50 are therefore positioned at about 90° from the plane 39 of center cover portion 38.
The nailer section 36 is made up of the nailer portions 52 and 54, respectively located in planes 53 and 55. Nailer portions 52 and 54 are formed by bending the material of which the anchor 30 is made along bend lines 56 and 58 about 45° outward, resulting in the planes 53 and 55. The plane 53 of nailer portion 52 is therefore about 45° from plane 49, and the plane 55 of nailer portion 54 is about 45° from plane 51, with planes 53 and 55 respectively being substantially parallel to planes 41 and 43. When it is desired that the side surfaces 48 and 50 of the anchor body area 34, and therefore their respective planes 49 and 51, be slightly splayed or non-parallel, the nominally 45° angles between planes 39 and 41 and planes 41 and 43 may be decreased at bend lines 44 and 46 in an amount in a range of about 0.1° to about 5°, resulting in the anchor 30's transverse distance A between bend lines 56 and 58 being slightly greater than the transverse distance B between bend lines 52 and 54.
In a similar manner, the nominally 45° angle between planes 49 and 53 and the nominally 45° angle between planes 51 and 55, and therefore the angle between side surface 48 and nailer portion 52 and the angle between side surface 50 and nailer portion 54, or either of these angles, may be either increased or decreased at bend lines 56 and 58 in an amount within a range between 0.0° to about as much as 45° to achieve the desired angular amount between the side surface 48 and the nail portion 52, and also to achieve the desired angular amount between the side surface 50 and the nail portion 54, so that the nail portions 52 and 54 are each able to be anywhere from being substantially perpendicular to their respective side surfaces 48 and 50 to being substantially parallel to those respective side surfaces. At times, it may be desired that the angular relationship between side surface 48 and nail portion 52 is to be different from the angular relationship between side surface 50 and nail portion 54. This is capable of being accomplished by changing the angles between those nail portions in relation to their respective side surfaces to differing angular amounts within the noted respective ranges.
One of the roof ridge tiles 60 is schematically sketched in to show the typical relationship of the roof ridge anchor 30 and the tiles 60. The tiles 60 are considered to be barrel tiles, and they have a curved inner surface 62 which engages the roof ridge anchor head 32 at either bend lines 44 and 46 or bend lines 52 and 54, or at three or all four of these bend lines. The detailed shapes of the tiles 60 are not further shown, however it is understood that they are of a typical construction and shape of any roof tiles that are or can be used as roof ridge tiles. The invention is in the roof ridge anchor and not in the tiles, although the disclosure shows a typical relationship between the roof ridge anchor and the roof ridge tiles used.
Roof ridge tiles are known to be secured to roof ridge anchors by various means. One example is the use of a screw or nail 70, as shown in

Parts 40a and 40b are joined together at bend line 144. The remaining upper part 40u of portion 40 and the part 40a have their adjacent edges joined at bend line 145. The remaining lower part 40L of portion 40 and the part 40b have their adjacent edges joined at bend line 147. The planar surface portion 38 is joined with part 40u at bend line 44 and portion 38 is also joined with part 42u at bend line 46.
Parts 42a and 42b are joined together at bend line 146. The remaining upper part 42u of portion 42 and the part 42a have their adjacent edges joined at bend line 151. The remaining lower part 42L of portion 42 and the part 42b have their adjacent edges joined at bend line 153.
Part 40a is in plane 148, part 40b is in plane 150, part 42a is in plane 152, and part 42b is in plane 154. The upper extensions of planes 41 and 43 are shown intersecting with an angle “f” at point 45, located above the planar surface center cover portion 38 in

When the cover is like cover 956 of
Essentially each cover 956 and 958, irrespective of its specific construction described above, has an upper portion 970, a lower portion 972 and an end portion 974. Both portions 970 and 972, whether installed or integrally made with the associated side surface, are spaced apart at a distance greater than the thickness of the outer edge surfaces 980 and 982 of the water leakage shield 984 to be described. This may be a relatively loose fit, making it easy to install shield 984. The covers 956 and 958 have drain openings 968 spaced along their end portions 974 so that the water leakage dripping or flowing from the drain openings 938, which then flows over the curved portion 986 of the shield 984, is directed by the outer edge surfaces 980 and 982 of the shield 984 toward the drain openings 968, from which they exit the anchor 930.
Shield 984 has a shallow dish-like curved portion 986 as seen in cross-section, and the outer edge surfaces 980 and 982 constitute linearly extending parts that readily snap into and through the openings 952 and 954 and yet do not fill the covers 956 and 958 so that water leakage going past the edge surfaces 980 and 982 are directed to flow out through the drain openings 968 of the covers 956 and 958. It is therefore preferable that the length of the tabs 990 and the width of the drain shield 984 be sufficient to have its edge surfaces 980 and 982 on the outer ends of the tabs 990 located outwardly of or below the bottom parts of the openings 952 and 954 once it is installed.
