' AWNINGS Filed April 29, 1954 2 Sheets-Sheet 1 INVENTOR. H m/K J' ZqEA/O wsk/ FITTOR/VEY United States Patent My invention relates to awnings more particulariv :to awning constructions wherein .a plurality of slats .are joined together in a manner to provide an awning .of

the fixed canopy or roll-up type.

some .of the principal objects of my invention is to pro- ,vide an awning construction wherein the slats are connected together along their lengthwise edges and are provided with means to preclude relative shifting of "the islets lengthwise.

Another object of my invention is to provide an awning of the foregoing described character which may be readily rolled in a minimum of space.

A further object of my invention is to provide an awning of the foregoing described character capable of being equipped with means for maintaining the slats in a substantially rigid condition to form a canopy and which means is eonnected to and disposed solely beneath the un- .der face of the canopy.

An important object of my invention is to provide, an awning of the foregoing described character which is simple in construction, ,durable and efficient in use, economical in manufacture and wherein the slats may be assembled and secured together against lengthwise displacement ;by .other than highly skilled labor.

With ,the above and other objects in yiew, as will hereinafter appear, the invention consists in the combination and arrangement of parts hereinafter set forth and illus- :trated in the accompanying drawings from which the several features of the invention and the advantages at- .tained thereby will be readily understood by those skilled in the art.

Referring ,to the drawings wherein like reference characters designate like parts throughout the several views:

Inp racticing my invention, as illustrated in the drawings, I provident awning 5 comprising a plurality of relaice tively narrow slats 6 the body portions of which are each slightly recurvated in transversality and provided with upper and lower faces 7 and '8 defining the upper .andiower surfaces '9 and 10 of the awning, respectively.

The longitudinalmargins of each slat terminate in upper and lower substantially spiral convolutions 11 and 12 disposed over and under the upper and lower .faces of the .slat. The upperand lowerconvolutions 11 and 12 of the slats are interconnected with the lower and upper convolutions 12 and -11 of the adjacent slats 6 to :provide hinges 13 for pivotly connecting the slats together to permit roll-up of the awning or serving to maintain the slats in connected relation when the awning is utilized as .a rigid canopy .as disclosed in Figures 7 and 8 and hereinafter more fully described.

The inneror free ends of the convolutions 11 and .12

tions or flanges 14arranged Ztocooperate with each other to prevent relative pivotal movement of the slats 6 in one direction materially beyond the surface plane of the awning when the slats arein extended position, as :shown in Figures 1 and 2, and to permit relative pivotal movement of the slats in the opposite direction, as shown in Figure 5, suificient to enable the awning to be rolled up to an inoperative position. Inasmuch as this feature, per se, does not constitute the present invention, a more detailed disclosure thereof is not deemed necessary, an exemplification of the feature being disclosed :in U. :5. Patent No. 2,099,408.

In order to preclude relative shifting of the slats lengthwise, the portions 16 of the convolutions on the lee side of each hinge, in proximity to the ends thereof and subjacent the lower face of a connected slat, are bent inwardly toward the axis of the hinge to form coacting indentations, detents, protuberances or aljutments d7. The detents 17 extend into the confines of the convolutions and in angular relation to the axis of the hinge '13. The detents 17 are formed or punched from the lower portions 16 by suitable means, for example, the tool disclosed in my copending application Serial No. 426,374, filed herewith, now Patent No. 2,748,866, granted June 5, 1956. The punching die assembly of the tool is .so constructed and arranged as to form and effect bending of the detents into the confines of the convolutions and in somewhat transverse relation thereto. As shown in Fig. 3, the indentation 17 preferably has an opening therethrough with the detents extending in pairs towards such opening. One of the pairs of detents may be longer than the other. A detent of each convolution is disposed in paired and abutting relation with a detent of the adjacent convolution. Each pair is relatively slidable to permit the aforementioned pivotal movement of the slats during rolling of the awning and of a sufficient width for engagement with each other at all times to preclude substantial relative axial movement of the convolutions and slats. Obviously, from the foregoing, it will be apparent that I have provided anti-shifting means effective for preventing relative axial movement of the convolutions and whereby the ends of the slats are maintained in a preestablished order with respect to each other at all times.

As illustrated in Figures 7 to 10, inclusive, of the drawlogs, the slats 6 may be maintained in fixed relation against transverse shifting or roll-up to provide an awning of the rigid canopy type and, for this purpose, I provide a pair of spaced supporting members, for instance, bars 20, disposed under the lower faces of the slatsand secured to a building or other structure from which the canopy extends. A plurality of anchoring plates 21 are employed for securing the slats to the bars 20 in fixed relation therewith. As depicted in Figures 8 and 9,

each of the plates is formed with a pair of side portions substantially hooked-shaped configuration whereby the latter is disposed between convolutions 11 and 12 of the hinge 13, as clearly illustrated in Figure 8.' The opposite side portion 23 is substantially fiat and, being angu larly related to the portion 24, extends in a somewhat general opposite direction with respect to the portion 22 and has its longitudinal free edge disposed in engagement with the bar 20. The bolt-holes 25 may be in the form of elongated slots for accommodating therein square-shaped head portions of bolts 26 to preclude turning of the bolts relative to the plates 21.

The bolts 26 extend through the center holes 25 of the plates 21 and the bars 20 and are provided with nuts 27 for tightening the bolts against the plates and therebyclamping the slats on the bars, it being understood that the plates are of a sufiicient resiliency to maintain the hinges in engagement with the bars under tension thereby securing the slats to the bars in a fixed condition to form a rigid canopy.

In instances where tubular or cylindrical members are employed in lieu of the bars 20, each of the plates 21, as illustrated in Figure 10, may be secured to a particular cylindrical member 30 by a U-clip 31 embracing the member 30 and having bolts 32 extending through its angularly-related end sections 33 and the outermost holes 25 of the plate 21 to secure the plate to the member in the same tensioned relation therewith as in the instance of the bars 20 heretofore disclosed.

It is to be noted that the detents are formed beneath the slats and substantially opposite from the weather or exposed sides of the hinges whereby the openings occasioned by the forming of the detents are concealed from view from without the awning, thus enabling the upper or outer faces of the slats to present a smooth and attractive appearance not marred by indentations, openings, bolt heads, etc. The lower or inner face of the awning also is attractive because the detents are disposed in zones which face in directions at angles to the directions in which the inner surfaces of the body portions of the slats face. Furthermore, while I have disclosed my invention in connection with slats preferably constructed of aluminum or the like, it is to be distinctly understood that the invention may be practiced in conjunction with slats constructed of other suitable and desirable materials. Also, it is comprehensible that the invention may be employed in connection with similar constructions other than the slats of awnings, for instance, panel assemblies for walls or the like wherein it is desirable to secure paneling against relative shifting. As clearly shown in Figure 6, groups of the detents 17 may be formed at each of the ends of the hinges whereby the detents of all of the groups coact to insure the slats against relative lengthwise shifting.

Without further elaboration, the foregoing will so fully explain the invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of service. Moreover, it is not indispensable that all the features of the invention be used conjointly since they may be employed advantageously in various combinations and subcombinations.

It is obvious that the invention is not confined solely to the use herein disclosed in connection therewith as it may be utilized for any purpose to which it is adaptable.

It is therefore to be understood that the invention is not limited to the specific construction as illustrated and described, as the same is only illustrative of the principles involved which are capable of extended application in various forms, and the invention comprehends all construction within the scope of the appended claims.
