ATTD RN EYS United States Patent O 2,993,571 ROOF ANCHOR Elgrin C. Hawkins, 108 E. Flora St., Tampa 41, Fla. Filed Nov. 26, 1957, Ser. No. 699,018 1 Claim. (Cl. 1189-34) This invention relates to building materials or construction, and more particularly to an anchor means for a roof.

The object of the invention is to provide a roof anchor which can be used for holding various types of roofs in place, and wherein the roofs may be of the corrugated type or wherein the roofs may be of the at type, and wherein the roofs can be secured in place without the necessity of using nails or other similar fasteners.

A still fur-ther object of the invention is to provide a roof anchor which will securely hold a corrugated or at roof in place on a building and wherein the roof does not have nails extended therethrough so that the possibility of the roof and nails becoming rusted is eliminated.

A further object of the invention is to provide a roof anchor which lis extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are used to designate like parts throughout the same.

FIGURE l is a fragmentary sectional view illustrating a corrugated roof being held in place by a roof anchor of the present invention.

FIGURE 2 is a sectional view taken on the line 2 2 of FIGURE l.

FIGURE 3 is a bottom plan view of the assembly shown in FIGURES l and '2.

.FIGURE 4 is a perspective view of the roof anchor shown in FIGURES l, 2 and 3.

FIGURE 5 is a fragmentary sectional view illustrating a modication, wherein a different type of roof anchor is shown for anchoring a at roof in place.

FIGURE 6 is a sectional view taken on the line 6-6 of FIGURE 5.

FIGURE 7 is a bottom plan view of the assembly shown in FIGURES 5 and 6.

FIGURE 8 is a sectional view taken on the line 8-8 of FIGURE 6.

FIGURE 9 is a perspective view of the roof anchor of FIGURES 5 through 8.

Referring in detail to the drawings, and more particularly to FIGURES l through 4 of the drawings, the numeral 10 indicates a section of a corrugated roof which includes upper curved portions or ridges 11 and lower curved portions 12, FIGURE l. The numeral 13 indicates rafters or beams which have strips 14 extending thereacross, `and the present invention is directed to a means for anchoring the roof 10 in place so that it is not necessary to use nails or the like.

According -to the present invention, there is provided a plurality of roof anchors which are each indicated generally by the numeral 15, FIGURE 4. Each of the roof anchors 15 comprises an upper semi-circular portion 16 which is arranged below a ridge 11 and which is secured in place thereto in any suitable manner, las for example by means of welding as at 17. The numeral 1S indicates wire-like members which are wrapped around or trained around a base 19 and strip 14. Thus, with the anchors 15 secured as by welding to the roof 10, `and with the anchors 15 secured by the wire members 18 to the strips 14, it will be seen that the roof will be securely anchored in place.

Referring now to FIGURES 5 through 9 of the drawings, there is shown a flat type of roof or roof section which is indicated by the numeral 20, and the numeral 21 indicates a section of sheathing which is provided with openings 22 therein. For anchoring the ilat roof 20 in place above the sheathing 21, roof anchors 23 are used, FIGURE 9, and the roof anchors 23 are each provided with a pair of coplanar at anges 24 which are secured to the undersurface of the roof 20 in any suitable manner, as for example by welding. Each anchor 23 further includes a support member or support portion 25 which extends through an opening 22 in the sheathing 21, and the support portion 25 comprises a pair of diverging arms 26 which have their lower ends joined by an arcuate portion 27. The numeral 28 indicates a wedge shaped pin which extends through the space between the arms 26 and portion 27 and the pin 28 is arranged below the sheathing 21 as shown in FIGURES 5 yand 7 for example.

From the foregoing, it is apparent that there has been provided a roof anchor which will effectively hold lroofs in place on buildings or the like and wherein it is not necessary to use nails or similar fasteners which have a tendency to rust and wherein such rusting can form holes in the roof which will let in rain. Thus, according to the present invention and for example as shown in FIGURES l through 4 the corrugated roof 10 may be anchored in place by positioning a plurality of anchors 15 beneath the ridges 11 and these anchors 15 have their upper curved portions 16 secured beneath the ridges 11 as by welding 17. Each anchor 15 further includes a lower or base portion 19 which is arranged contiguous to the .upper surface of the strip 14, and wire members 18 surround the bases 19 and strips 14. Thus, with the strips 14 extending across roof rafters 13, it will be seen that a highly effective means is provided for anchoring the roof 10 in place.

In FIGURES 5 through 9 there is illustrated a roof anchor for securing a at type of roof 20 in place on the sheathing 21. Thus, as shown in the drawings the sheathing 21 is provided with openings 22 whereby the portions 2S of the anchors 23 can be extended through these openings 22. The anchors 23 have their upper flanges 24 secured as by welding to the lower surface of the roof 20, and the anges 24 may be secured to the roof 20 as by welding. A wedge shaped pin 28 extends through the spaces between the arms 26 and lower portion 27 whereby the roof 20 will be securely anchored in place.

Thus, according to the present invention, it will be seen that a means is provided for anchoring roofs in place on buildings, and wherein the roofs may be of the corrugated or fiat type. It is -to be understood that the number of roof anchors `can be varied as desired, and also the parts can be made of any suitable material and in different shapes or sizes.

In FIGURES l, 2 and 3, if desired the anchors 15 may be arranged at 18 inch intervals and the roof anchors can be made in diierent sizes so as to lit corrugated roofs of diierent sizes or shapes. The anchors can also be used on channel rooting and the anchor of the present invention will eliminate the necessity of using nails or nail holes so that leaks around the nails will be eliminated and wherein rusted nail holes will be prevented. Furthermore, the present invention will eliminate the necessity of renailing roofs, and the life of the roof will be extended or prolonged and wherein a minimum amount of upvkeep or repair will be required during the life of the roof.

Minor changes in shape, size and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.

What is claimed as newrfisas follows:

In combination, rafters, strips extending across said rafters, a corrugated roof arranged above said strips and rafters and said roof including spaced apart arcuate ridges, roof anchors each comprising a semi-circular upper portionv arranged contiguous tothe lower surface of' a ridge and secured thereto, said roof anchor further including a lower rectangular base that is integral at'its opposite outer edges with the lower edges of said lupper portion and is arranged contiguous to Ythe upper surface of a strip, yand wire mmebers trained around said base and strip.
