ATTORNEYS SUPPORT FOR PANELS AND THE LIKE The present invention relates to a support for reinforcing panels and the like and particularly relates to an improved support for use in reinforcing under-the-eave soffit panels and to a packing assemblage of such supports.

Conventional methods of providing soffit panels under the eaves of residential roofing have required socalled look-out members secured to extend horizontally between the ends of diagonal roofing members and the side frame of the house. These look out members are usually individually cut and nailed into position at considerable cost and labor. The sofiit panels would then be nailed or otherwise secured to the undersides of the look-out members, the lookout members preventing bowing, sagging, and other deformation of the soffit panels.

A known method of eliminating the use of these look-out members employs a plurality of sheet metal supports, fixed to the upper surfaces of the soffit panels by means of triangularly configured teeth struck from the supports and embedded into the soffit panel. These supports are intended to reinforce the soffit panel against bowing, sagging, etc. when the latter are secured between the ends of the diagonal roof members and the side of the house. These supports are provided in short lengths and when the soffit panel is too wide for use of a single support, the supports are combined in a substantially end-to-end relation to span the panel. This has not proved successful and some sagging still occurs. Furthermore, such sheet metal supports as have been provided heretofore have relatively low upstanding flanges which provide a magnitude of moment of inertia insufficient to provide a high resistance to bending moments and thereby such supports do not effectively prevent undesirable sagging or bowing of the soffit panel. Still further, packaging these known supports for shipment has proven to be difficult, laborious and cumbersome due to their channel configuration. The resulting packages are bulky as space saving techniques cannot be employed with supports formed to this configuration and this greatly increases the shipping costs of such supports.

According to the present invention, there is provided an improved support in the form of an elongated sheet metal plate having generally upstanding outwardly flaring sides with the base or intermediate portion therebetween having a plurality of nail-like teeth struck to extend therefrom in the opposite direction for embedment into the panel. Outwardly extending flanges project from the upper edges of the sides whereby the moments of inertia of the support members are greatly increased. This makes it possible for a given cross section of metal to provide far greater support and superior resistance to bending moments than is feasible with the above described known support members.

It is a particular feature hereof that the present support members are formed to nest, one within the other, whereby an efficient packing assemblage from a space saving standpoint is provided. To accomplish this, the sides of the present support are flared outwardly as to permit reception of one or more like and similarly oriented supports in nesting relation therewith. In one form of the packing assemblage hereof, the sides of the supports are flared outwardly such that the intermediate base portions of the supports are spaced, one

from the other, whereby the tips of the teeth of overlying supports are spaced from the base portions of the underlying supports. In a further form hereof, sides of the supports are flared to a greater extent such that the supports assume a close nested relation each with the other with the teeth of the overlying supports extending through the slots left in the base portions of one or more of the underlying supports. To facilitate the nesting of the supports, lateral edges of the teeth are slightly tapered in an inward direction so That the teeth of the superposed supports do not interfere with or otherwise engage the lateral edges of the slots of the underlying supports when these latter forms of packing assemblages are employed.

To increase the resistance to withdrawal of the teeth in the panel, the ends of the laterally adjacent teeth are scarfed in opposite lateral directions whereby a clinching action is provided upon embedment of the support into the panel. In a further form, the next adjacent longitudinally spaced teeth are scarfed in opposite directions whereby such teeth also provide a clinching action.

Accordingly, it is a primary object of the present invention to provide an improved support for reinforcing panels and the like and particularly to provide an improved support for under-the-eaves soffit panels.

It is another object of the present invention to provide an improved sheet metal support for reinforcing panels and the like which is characterized by a high moment of inertia for a given cross section of metal.

It is still another object of the present invention to provide the soffit panel and reinforcing support therefor wherein sagging, bowing, and other deformations of the panel are substantially precluded.

It is a further object of the present invention to provide improved supports for reinforcing panels and the like wherein the supports are formed to nest one within the other to provide an efficient packing assemblage.

It is a still further object of the present invention to provide a packing assemblage comprising supports having the foregoing characteristics and wherein a great number of supports can be packaged in a minimum of space.

These and further objects and advantages of the present invention will become more apparent upon reference to the following specification, appended claims and drawings wherein:

FIG. 1 is a fragmentary perspective view of an underthe-eave soffit panel employing a reinforcing support constructed in accordance with the present invention;

FIG. 2 is an enlarged fragmentary plan view of the support hereof;

FIG. 3 is an enlarged cross section of a plurality of supports of the type illustrated in FIG. 2 and shown in nested relation one within the other;

FIGS. 4 through 6 are respective enlarged cross-sectional views of several forms of supports hereof and illustrating a plurality of supports in each form thereof in nested relation one within the other; and

FIG. 7 is a fragmentary plan view of the support illustrated in FIG. 6.

Referring now to the drawing, particularly to FIG. 1, there is shown a plurality of under-the-eave soffit panels indicated at 10 finally secured in end-to-end relation and extending transversely between the lower ends of the overhanging diagonal members ,12 of a roofing structure and the side frame 13 of, for example, a house, generally indicated at 14. Panels are provided with conventional screened vents 16. The panels 10 may be secured to the members 12 by nailing through the outer edge portions thereof into the lower ends of members 12 by use of molding, not shown, or preferably by rabbeting them as at 17 to fascia panels 18 which, in turn, are nailed to the outwardly facing ends of member 12. The inner edge portions of panels 10 may be secured to housing frame 13 by nailing to a strip 19 secured to housing frame 13 or may be supported on a molding 20 secured to housing frame 13. Suitable spacers 22 are provided between longitudinally adjacent panels 10. A plurality of longitudinally spaced, transversely extending supports, generally indicated at 26, are secured along the upper faces of panels 10 and provide reinforcement to the panels whereby bowing, sagging and other deformations thereof are effectively precluded. It will be appreciated that supports 26 may be employed with other types of panels and that the under-the-eaves soffit panel system herein described and illustrated with reference to FIG. 1 is to be considered as exemplary only and not a limitation on the use of supports 26.

Referring now to FIGS. 2 and 3, each of supports 26 comprises an elongated strip of sheet metal, preferably 28 U.S. standard gauge,bent about longitudinally extending laterally spaced fold lines 28 to form a pair of laterally spaced upstanding sides or edge portions 30 defining a base or intermediate plate portion 32 therebetween. For reasons as will presently become clear, sides 30 are bent to incline or flare outwardly in a lateral direction from base portion 32 such that the includ'ed angle between sides 30 and base portion 32 is greater than 90 degrees. Upper edge portions 34 of sides 30 are bent about longitudinal fold lines 36 in opposite directions to form a pair of upper flanges which project laterally of support 26 and preferably in a plane parallel to the plane containing base portion 32.

A plurality of nail-like teeth 38 are struck downwardly from base portion 32 to extend substantially normal to and from the underside of base portion 32. Teeth 38 are struck such that the slots 40 left thereby extend from the teeth in like longitudinal directions. As illustrated in FIGS. 2 and 3, teeth 38 are struck to form a pair of longitudinally extending, transversely spaced, rows of teeth with the teeth in each row lying laterally adjacent the corresponding teeth in the other row. The teeth 38 are preferably struck to provide a shallow V-shape cross section as at 39 whereby the teeth are reinforced along their lengthwise extending axes. As best seen in FIG. 3, teeth 38 have scarfed ends 44 with the ends of laterally adjacent teeth being scarfed in opposite directions to provide a lateral clinching action upon embedment of such teeth into a panel. For reasons as will become clear, the lateral edges 46 of teeth 38 are tapered slightly inwardly as to converge in a direction away from the base of the teeth.

In a preferred form hereof, supports 26 are formed of 28 U.S. standard gauge galvanized sheet metal having a nominal thickness of 0.018 inch. It will, of course, be

' appreciated that sheet metal having other thicknesses,

for example, 24 U.S. standard gauge, may also be utilized. The width of base portion 32 is preferably 1 inch and the height from the lower face of base 32 to the upper face of flanges 34 is preferably 0.6 inch. The respective sides 30 form included angles with bease portion 33 of The teeth are longitudinally spaced one from the other along support 26 on 1% inch centers but may be spaced 2 inches apart if desired. Teeth 38 are 0.1 inch wide at their base and have a length about 0.375 inch. The included angle of the V-shaped teeth is preferably and the ends of the teeth are scarfed preferably at 45 angles. The supports are provided in lengths depending on their use so that the supports span the associated panels from edge to edge to avoid a splice intermediate the panel edges.

In use, supports 26 are pressed into a panel face, for example, upper face of panel 10 shown in FIG. 1. This can be accomplished by inserting, for example, a l-inch wide board between the sides 30 and hammering along the outer edge of the board thereby driving nails 38 into the panel. As will be readily appreciated, the scarf pointed ends 34 of teeth 38 tend to bend the teeth 38 laterally outwardly upon embedment into the panel whereby a lateral clinching action is effected, thus assuring retention of the supports 26 on the face of the panel and providing a high resistance to withdrawal of the teeth from the panel.

By forming a relatively narrow base or intermediate portion 32 and forming the flanges 34 along the upper edges of sides 30, a substantial moment of inertia about the neutral axis of the support is provided. This is a significant increase as compared with supports previously employed for this purpose. It will therefor be appreciated that the present support, by developing this relatively high moment of inertia, can resist substantial bending moments and thus is effective to prevent sagging, bowing, and other deformation of the panels, such as for example, the soffit panels 10 illustrated in FIG. 1.

It is a feature of the present invention that supports 26 are particularly formed whereby the same may be located in nested relation, one with the other, as to provide a space-saving, packing assemblage. To this end, the sides 30 flare outwardly and, in the form of support illustrated in FIGS. 2 and 3, respectively, form included angles of about 100 degrees with base portion 32. By flaring sides 30, supports 26 may be nested or inserted one within the other with the outer faces of the sides 30 of each support engaging the inner faces of the sides 30 of the support next below. In the packing assemblage illustrated in FIG. 3, the sides 46 of teeth 38 taper inwardly as to be receivable within the slots 40 left by the teeth struck in the support 26 packaged next below. Thus, when lying in the nested packing assemblage with the teeth 38 of each support 26 engaging through the slots 40 of the support 26 next below, it will be seen that the teeth 38 do not interfere with the nesting arrangement forming the packing assemblage hereof. The support strips 26 can thus be packaged one within the other whereby considerable savings in space is effected. Also, with the side walls of the nested supports 26 engaging and forming a friction fit with one another and the teeth of the superposed supports extending through the underlying supports, it will be seen that a stable and orderly array of supports can be provided in the packing assemblage. Note that with a flare angle of 100, the base portions 32 of the next adjacent nested supports are spaced one from the other whereby the teeth of the superposed supports extend only through the slots of the supports next below.

Referring now to FIGS. 4 through 7, there are illustrated three additional forms of supports hereof, each form being similar to the form illustrated in FIGS. 2 through 3 and having like reference numerals assigned succeeded by the letter notation a-c, respectively to designate like parts. As seen in FIG. 4, the sides 30a of support 26a flare outwardly at a greater angle than the sides 30 of the support 26 illustrated in FIGS. 2 and 3, and, in this form, flare outwardly to form included angles of about 120 with base portion 32a. By providing this large flare angle, supports 26a can be disposed in close, nesting relation, each with the other, and, in this form, the teeth 38a of the superposed supports 26a extend through each of the slots 40a left by the teeth struck from the next four underlying supports 26a.

Another form of support is illustrated in FIG. 5 and, in this form, the sides 30b of supports 26b flare outwardly 'to form included angles of 105 with base portion 32b. The teeth 38b extend through the slots 40b of the two next lower supports 26b in this packing assemblage and it will be seen that the bases 32b of the respective supports 26b are spaced closer together than the corresponding spacing illustrated in the packing assemblage of FIG. 3 and are spaced further apart than the packing assemblage illustrated in FIG. 4.

In the form of support illustrated in FIGS. 6 and 7, the sides 30c of supports 26c flare outwardly to form included angles with base portion 32c of 95. It will be seen that in this packing assemblage, tips of the teeth 38c are spaced from the base portions 32c of the next underlying support 26c when supports 26c lie in nested relation one to the other. In this form, the side edges of the teeth 38c need not be tapered inwardly and may lie in parallel relation, one with the other, although such sides are preferably slightly inwardly tapered toward one another to provide for easier insertion. The ends 440 of teeth 58c of each laterally spaced pair of teeth are, as before, scarfed in opposite lateral directions. However, the ends of teeth 380 comprising longitudinally adjacent pairs of teeth are scarfed in opposite directions as seen in FIG. 6 and as indicated by the oppositely scarfed ends of the slots 400 left by the struck teeth (FIG. 7); alternating laterally inward and outward clinching actions are provided along the length of the support upon embedment into the panel member.

It will be appreciated that the nested supports 26a are offset longitudinally one from the other, in the forms of supports hereof illustrated in FIGS. 2 through 5, at least a distance equal to the thickness of the metal sheet from which the supports are formed. The supports in the form hereof illustrated in FIGS. 6 through 7, may be nested, one within the other, without regard to the relative locations of the teeth of the next adjacent supports as their teeth need not register through the slots of the next adjacent supports whereas the sup ports comprising the packing assemblages illustrated in FIGS. 2 through 5 must be aligned such that the teeth thereof engage through the slots of the next adjacent supports. The latter type supports are accordingly prevented from substantial longitudinal movement when in the packing assemblage due to the engagement of the teeth through the slots of the underlying support(s) and thus provide a stable, substantially nonslipping packing assemblage.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore to be embraced therein.
