INVENTORS RALPH L. FRIEND 8. CHESTER C. KNAPP ATTORNEYS FIG-2 Patented May 1, 1951 UNITED STATES F'ENT FHCE AWNING of Ohio Application May 10, 1947, Serial No. 747,274

3 Claims.

This invention relates to awnings and more particularly, to awnings of the permanent type in which the horizontal blades or slats are fixed or rigidly maintained in their respective spaced positions.

The present invention has for its primary object the provision of an awning which is characterized by its structural simplicity, its economy of manufacture, the ease of assembly of its parts, and its long service life.

A more specific object of the present invention is the provision of an awning which may be sold in unassembled form, within a conveniently handled package, and readily and quickly assembled and mounted in place by the purchaser thereof.

A further object of the present invention is the provision of an awning in which at least the majority of its blades or slats are permanently retained in horizontal position and at different levels by simple and inexpensive tongue and groove means.

A further object of the present invention is the provision of an awning in which at least the majority of its blades or slats are supported and rigidly retained in their respective positions by a series of sheet metal links, with each pair of such links supporting and rigidly retaining the lower edge portion of one blade or slat and the upper edge portion of the next lower blade or slat.

A further object of the present invention is the provision of an awning having a plurality of laterally spaced depending frame members and a plurality of blades or slats extending across said frame members and disposed at different levels, said frame members and at least the majority of said blades or slats being provided with apertures to receive the end portions of sheet metal links by which such apertured blades or slats are supported and rigidly retained in position, said link end portions being of bendable nature for quick and easy securement of said links to said frame members and to such blades or slats.

Further objects of the present invention, and certain of its practical advantages, will be referred to in or will be evident from the followingdescription of one embodiment of the invention, as illustrated in the accompanying drawing, in which Fig. 1 is a perspective view of an assembled awning constructed in accordance with the present invention;

Fig. 2 is a side elevational view of such awning, as mounted in place for use thereof, a portion of the side flange of one of the frame members of the awning being broken away;

Fig. 3 is a detail sectional view, on the line 33, Fig. 2;

Fig. 4 is a front elevational view of the left side frame member of the awning, in its initial flat form or condition;

Fig. 5 is a similar View of the right side frame member;

Fig. 6 is a perspective view of the left side frame member in its bent form as used in the awning; and

Fig. '7 is a perspective view of one of the sheet metal links which support and retain the majority of the blades or slats of the awning in their fixed positions.

Before specifically describing the awning here illustrated, it is to be understood that the invention here involved is not limited to awnings of the particular construction or the particular arrangement of parts here shown, as awnings embodying the present invention may take various forms. It also is to be understood that the terminology or phraseology herein used is for purposes of description and not of limitation, the scope of the present invention being denoted by the appended claims.

The awning here shown, for the disclosure of one form of the present invention, comprises two or more laterally spaced frame members connectible at their upper ends to the top of a window frame, such as the frame A, Fig. 2, and extending downwardly and outwardly therefrom, as best shown in Fig. 2. Although there may be three (or even more) such frame members in a particularly wide awning, in the awning here illustrated there are two such frame members, namely, a left side frame member H3 and a right side frame member l I. These frame members may be, and here are, simple elongated strips stamped from sheet metal in flat form, as shown in Figs. 4 and 5, and subsequently bent along their 1ongitudinal axes I2 into right-angular form, as shown in Fig. 6, to thereby provide each frame member with a front flange l3 and a side flange 14. Each frame member is also bent about a transverse line 5, to provide each frame member with a top end portion 6 extending inwardly at any desired angle, such as an angle of de grees, from the main section of the frame member. To eliminate buckling and the like of the side flanges M at this bend, the side flange of each frame member is provided, in lateral align ment with the bend line I5 and while the frame member is in its initial flat form, with a transverse slit H which may, if desired and as here shown, terminates in an aperture [1a to prevent undesired extension of such slit. Upon bending of each frame member about its bend lines l5, the side flange portions on opposite sides of the slit H are brought into overlapping relationship, as shown in Fig. 6, and such overlapping side flange portions are welded at l8 or otherwise rigidly united, as shown in Fig. 6.

As will be evident from a comparison of Figs. 4 and 5, the two frame members W and II are of identical form, the only difference therebetween is that one of the members is turned over before its side flange M is bent down, to thereby provide a right side frame member and a left side frame member, each with its side flange disposed on the outer side thereof in use in the awning.

Extending across the lower ends of the two depending frame members I and H and suitably secured thereto is a base strip 25, the length of which is preferably equal to that of the width of the awning. As here shown, said base strip is a simple sheet metal member of right angular form, with a front flange 2| overlying and secured to the front flanges l3 of the frame members Hi and ii, and with a bottom flange 22 extending inwardly toward the window frame and located just below the lower end edges of said frame members. In order to enable the present awning to be sold in unassembled form and easily and quickly assembled by the purchaser thereof, bolts and nuts 23 are here used for the securement of the base strip 28 to the frame members H) and H, the front flange 2| of such base strip and the front flanges E3 of such frame members being provided with aligned apertures 24 for the reception of the bolts. Although the spacing of the frame members I0 and H may be varied as desired, in the awning here shown the spacing of the frame members is such that the end portions of the base strip 29 project laterally therebeyond. However, in an awning in which three frame members are used, the two side frame members preferably would be located at or substantially at the ends of said base strip.

To maintain the base strip 29 and hence the lower ends of the depending frame members H! and I in proper outwardly spaced relation with respect to the window frame A, the awning ineludes two strut bars 2'5 which may be of any suitable form and material. As best shown in Fig. 2, these strut bars extend between the ends of the base strip 2d and the window frame A, the outer ends of the strut bars (here shown as of flattened form) overlying and being suitably secured to the bottom flange 22 of the base strip and the inner ends of the strut bars being connectible to the window frame. For convenience of assembly, the strut bars are here secured to the base strip 2 by bolts and nuts 27, for which suitable apertures are provided, and the inner ends 28 of the strut bars are bent down and suitably apertured for the reception of attaching screws 29.

Extending horizontally across the depending frame members i0 and H, and located at different levels therealong, are a series of blades or slats, there being five such blades or slats, designated by the reference numerals 3| to 35 inclusive, in the awning here illustrated. Although such blades or slats may be of any suitable material, they are here simple sheet metal stampings, with downturned bottom edge flanges 36 and upturned top edge flanges 31, as shown in Figs. 1 and 2. For manufacturing economy, the blades or slats are of identical character or construction except as to the apertures with which they are provided and which are hereinafter referred to. The two uppermost blades or slats iii and 52 each has a somewhat different arrangement of apertures, but as the other blades or slats 33, 34 and 35 have the same arrangement of apertures, these three blades or slats are completely identical and therefore interchan eable. Preferably, the width of each blade or slat is such that the uppermost blade or slat 3| not only completely covers the inwardly bent top portions is of the two depending frame members |l and H, but projects downwardly and outwardly therebeyond sufficiently to enable the upturned top edge flange 3'! of the next lower blade or slat 32 to be located behind the downturned bottom edge flange 36 of such uppermost blade or slat 3|. As to length, the blades or slats preferably are of the same length as that of the base strip the length of the blades or slats and the base strip 29 determining, of course, the width of the awning.

For the rigid securement of the uppermost blade or slat 3| to the top portion l8 of the two frame members l0 and H, the front flange IQ of such top portions l6 and the overlying or registering portions of the blade or slat 3| are provided with registering apertures 38 through which securing means may extend. To enable a purchaser of an unassembled awning to readily secure the uppermost blade or slat 3| in place, bolts and nuts 39 are here utilized for the securement of such blade or slat, as shown.

For the support and rigid retention of the lower edge portion of the next lower blade or slat 32 (the upper edge portion of which blade or slat is supported and retained by locating its upturned top edge flange 31 behind the downturned bottom edge flange 36 of the topmost blade or slat 3|) and for the support and rigid retention of the top and bottom portions of the remaining blades or slats 34 and 35, there is here utilized a series of identical links having bendable end portions extending through apertures in said blades or slats and in said depending frame members It and H for effecting such support and rigid retention of said blades or slats.

In the form here shown, said links are simple and inexpensive sheet metal members, each having a rigid body portion 42 and reduced end portions G3 and 4-2, the reduction of such end portions not only enabling them to be bent, as will hereafter appear, but also providing the link at the ends of its body portion with stop shoulders and 56, as best shown in Figs. 3 and 7.

To receive the bendable inner end portion 43 of these supporting and retaining links, the front flanges l3 of the depending frame members In and ii are provided with longitudinally spaced transversely elongated apertures or slots 48, and the upper edge (there being two such apertures or slots, in lateral alignment, for each pair of links) portions of the blades or slats 33, 34 and 35 are provided, adjacent their upturned top flanges 3'1, with corresponding apertures or slots To receive the bendable outer end portions i l of these supporting and retaining links end portions which may be, and here are, somewhat shorter than the end portions 43) the lower edge portions of the blades or slats 32, 33, 34 and 35 are provided, adjacent their downturned bot tom edge flanges 36, with corresponding apertures or slots 50.

As shown in Figs. 1 and 2, two of these links, designated by the reference numeral 52, are utilized for the support and rigid retention or the lower edge portion of blade or slat 32 and the upper edge portion of the next lower blade or slat 33. For the support and rigid retention of the lower edge portion of the blade or slat 32, the outer end portions d4 of such links 52 are extended outwardly through the apertures or slots 56 of such blade or slat, and with such blade or slat resting on the outer shoulders 46 of such links, the projecting free ends of the link outer end portions 44 are bent downwardly alongside the downturned bottom edge flange 35 of such blade or slat, with the consequent clamping of the lower edge portion of said blade or slat between the shoulders 48 and the downwardly bent link ends. For the support and rigid retention of the upper edge portion of the next lower blade or slat the inner end portions 33 of the links 52 are extended inwardly through two laterally aligned apertures or slots '18 in the front flange it of the depending frame members l6 and H and through the apertures or slots 49 in the upper edge portions of such blade or slat 33. With the inner shoulders 55 of such links bearing or pressing against such blade or slat 33, the projecting free ends of the 1 link inner end portions 43 are bent upwardly alongside the rear surfaces of the front flanges of the frame members iii and H, with the consequent clamping confinement of such front flanges and the upper edge portion of the blade or slat 33 between the shoulders 4t and the upwardly bent link ends.

In a similar manner, a pair of links designated by the reference numeral 53 support and rigidly retain the lower edge portion of the blade or slat 33 and the upper edge portion of the next lower blade or slat 3d; and a pair of links desig nated by the reference numeral 54 support and rigidly retain the lower edge portion of the blade or slat 3t and the upper edge portion of the lowest blade or slat 35. For the support and rigid retention of the lower edge portion of such lowest blade or slat 35, a pair of links designated by the reference numeral 55 is utilized, the outer end portions 44 of such links being secured in the apertures or slots 5d of such blade or slat in the manner heretofore described. Inasmuch as these links 55 do not support or retain the upper edge portion of a blade or slat, the inner end portions 43 of such links merely extend inwardly through a pair of aligned apertures or slots 48 in the frame members it? and ii, and with the inner shoulders d5 of such links in engagement with the front surfaces of said frame members, the projecting free ends of such link end portions are bent upwardly against the rear surfaces of said frame members to thereby rigid ly clamp the inner end portions of said links to said frame members and to support and rigidly retain the lower edge portion of the lowest blade or slat 35 in spaced relation to said frame members.

For the top mounting of the present awn ing, the side flanges l of the top portions it of the two frame members iii and l l are here provided with notches 5?, Figs. 2 and 6, for the reception of rod-like supporting means 58 suitably secured to the top portion of the window frame A. Therefore, by hooking the top portions it of the frame members It and II over said rod-like supporting means 58 and securing the inner ends 28 of the strut bars 26to the window frame, the awning can be easily, quickly and conveniently mounted in place, as shown in Fig. 2, and removed when desired.

From the foregoing description of the awning here illustrated, it will be evident that such awning is of simple and inexpensive form, capable of being manufactured and sold at low cost, and capable of being sold in unassembled form for ready and convenient assembly and mounting by the purchaser thereof. Other features and advantages of the awnings embodying the present invention will be evident to those skilled in the art to which the present invention relates.
