9 Claims. (Cl. 16023'5) My invention relates to awnings and more particularly 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.

One of the principal objects of my invention is to provide an awning construction wherein the slats are connected together along their lengthwise edges and are provided with means to preclude relative shifting of the slats 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 connected to and disposed solely beneath the under 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 eificient 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 View, as will hereinafter appear, the invention consists in the combination and arrangement of parts hereinafter set forth and illustrated in the accompanying drawings from which the several features of the invention and the advantages attained 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:

Reissue-d July 28, 1959 2 Figure 10 is a detail perspective view illustrating the manner of securing the plate to a cylindrical support.

1 In practicing my invention, as illustrated in the drawings, I provide an awning 5 comprising a pluraliay of relati vely narrow slats -6 the body portions of which are each slightly recur-vated in transversality and provided with upper and lower faces 7 and 8 defining the upper and lower surfaces 9 and 10 of the awning, respectively. The longitudinal margins 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 upper and lower iconvolutions 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 inner or free ends of the convolutions 11 and 12 of each hinge 13 are formed with relatively straight portions or flanges 14 arranged to cooperate 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 are in 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, sulficient 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 US. 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 subj-acent the lower face of a connected slat, are bent inwardly toward the axis of the hinge to form coacting indentations, detents, protuberances or ajutments 17. [The] As shown in the drawings, the overlying sections of the hinges have elongate indentations defining delents which extend lengthwise of the hinges. The indentations are generally U-shoped in transverse section and are of decreasing depth toward one end thereof. The underlying sections of the hinges have similar and correspondingly oriented indentations forming pockets which receive and confine the detents and prevent the slats from sliding relative to each other along the axes of the hinges while providing sufiicient articulation of the hinges to permit rolling of the awning.

In the particular form of the invention shown in the drawing, the overlying hinge sections are cut or pierced transversely and the indentations 17 extend from and are of maximum depth at these cuts. Also, each indentation 17 is here shown as having two detents, one a! each side of the out. However, as perhaps best shown in Fig. 3, the detents at one side of the cuts are considerably deeper than the detenzs at the other sides of the cuts and it will be appreciated that the relatively deeper detents are primarily efiective in holding the slats against relative longitudinal movement. As stated above, the underlying sections of the hinges are similarly formed with indentations 17 which are similar to and correspondingly oriented with respect to the indentations 17 in the outer hinge sections. In the particular form of the invention shown, the indentations 17 in the underlying hinge sections also are pierced or cut transversely and they also have dctenis at opposite sides of the cuts which pocket and confine corresponding detents in the outer hing sections. It will be appreciated in this connection,

however, that the important thing is to form deients in the outer hinge sections and coacting indentations or pockets in the inner hinge sections, the detents being of sufiicient depth and size to lock the slats against relative longitudinal movement and formed and oriented in the hinges so as to permit suflicient articulation of the hinges to permit rolling of the awning.

Referring now once more to the particular form of the invention shown in the drawings it will i be observed that 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 sufiicient 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 ap parent that I have provided anti-shifting means effective for preventing relatiwe 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 drawings, 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 slats and secured to a building or other structure fromwhich 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 22 and 23', respectively, and an intermediate portion 24.

The intermediate portion 24 is relatively flat and is provided with a ternary of bolt-holes 25. The side po tion 22 is angularly related to the portion 24 and of a 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 flat and, being angularly 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 thereby clamping the slats on the bars, it being understood that the plates are of a sufficient 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 Uclip 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 fcatures of the invention be used conjointly since they may be employed advantageously in various combinations and subcornbinations.

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.
