AWNING.

. Application filed August 3, 1928 Serial No. 297,202.

This invention relates to a-metal awning especially designed for store front installation, or Wherever a relatively wide and ex? ceptionally strong construction is desired, but is nevertheless adapted for use generally at windows, doors, and transoms.

It is particularly aimed to provide such an awning which is composed of sheet metal sections adapted to be extended or collapsed at will and operated and supported primarily by a latticed cantilever or lazytong truss.

A further object of the invention is to provide an awning of this character wherein the mounting for the truss is extensible to accommodate movement of the awning, and wherein the parts are protected and efficiently supported when retracted or collapsed.

More specific objects and advantages will become apparent from a consideration of the description following taken in connection withthe accompanying drawings illustrating an operative embodiment.

In said drawings:

Figure 1 is a perspective view showing the awning in extended position;

Figure 2 is a fragmentary plan View showing the operating shaft and its connections;

Figure 3 is a sectional view taken transversely through the awning in extended position; j

Figure 4 is a view similar to Figure 3 but with the awning retracted; I

Figure 5 is a detail of one of thesupport- I ing brackets used between the awning sectime and truss, and t Figure 6 is a detail perspective view of tho extensible section of the truss mounting.

Refe'rringspecifically to the drawings, the awning proper consists of any desired num ber of mtermediateroof leaves or sections 10, a relatively wide stationary hood section 11,

ding of rain therefrom and the flanges 17 prevent passage of rain through the awning.

'The said awning sections are adapted to be projected into the position of Figure 3 where the hook flanges 17 are engaged, or retracted into the position of Figure 4 Where the hook flanges 17 are disengaged and the sections 10 and 12 are compactly superposed and at.- finged substantially under the hood section The awning sections are supported in both extended and retracted positions by a plurality of parallel latticed cantilever trusses generally designated 19,"three of them being shown in Figure 2 by way of ezfamplel Each truss consists of bars 20 pivotally connected together by pins 21, nd the apron section 12 is rigidly fastened to the front bar 20. Each section 10 has a bracket 22 rigid therewith and depending therefrom, and-the brackets 22 progressively increase in height from the front to the rear of the awning and are 1, and a supporting bracket 24 for each truss 19 is located beneath said section. Each bracket 24 is bolted as at '25 to an attaching plate 26, which in turn is bolted or otherwise fastened as at 27 to the front wall of the building 23. Upper and lowerarms 28 and 29 ong each bracket 24 are inclined downwardly and forwardly, and the former is longer than the latter. Rigidly fastened in said arms 28 and 29 at a right angle thereto so as to be inclined is a sleeve or tubular support 30, and a rod or support 31 is telescoped therein to slide relatively thereto. Clips 32 and 33 are fastened rigidly to said sleeve 30 and rod 31, respectively, and the adjacent bars 20 are pivotally connected thereto by pins 34. The rod 31 is moved endwise automatically as the and a front or apron section 12, all of which truss is contracted or extended and accommodates the variation in the width of the truss according to the positions it assumes, as contrasted in Figures 3 and 4. As shown in Figure'4, each rod 31 when projected may engage the front of building 23 so that the structure generally will be braced.

Carried by the arms 28 are bearings 35 in which an operating shaft 36 is journalled. On said shaft 36 are mounted one or more drums 37 to which one end of draw cables or chains 38 are/"fastened, the other ends of the I cables being secured as at 39 to the apron section 11. Anydesired means may be used to v turn the shaft 36' as, for instance, a vertical shaft 40 geared thereto at 41 and operable by a crank 42 geared at 43 to shaft 40.

As a result of the construction described, the shaft 36 is rotatable to wind the flexible elements 38 thereon and thereby retract the sections 10 and 12 and lazytong bars 20, moving them from the position of Figure 3 to that of Figure 4. Extension of the parts "to the position of Figure 3 is limited by the engagement of the hook flanges 17. The conventional mechanism for operating shaft 36 includes a means to hold such parts retracted. When the parts are released due to their arrangement and inclination, they move by gravity to the extended position of Figure 3. In'each position of the awning, it will effectively shed rain, and the various parts are efficiently supported and braced.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

What is claimed is:

1. An awning structure comprising a lazytong truss, and a collapsible awning connected to various parts of the truss.

2. An awning structure comprisin a collapsible truss, an awning positioned by said truss, and a mounting means for the truss having relatively movable parts to accommodate automatically variation in the width of the truss in the different positions thereof.

3. An awning structure comprising a collapsible truss, an awning, brackets extending from various parts of the truss and supporting said awning, said brackets progressively increasing in length from front to rear of the awning.

4. An awning structure comprising a lazytong truss, brackets extending from various pins at the joints of the truss, and awning sections rigidly'connected to said brackets.

5. An awning-structure comprisin a supporting bracket, a relatively movab e supporting tube and rod carriedthereby, a lazytong truss having adjacent bars fastened to said tube and rod, and an awning positioned by the truss.

6. An awning structure comprising a supporting bracket, inclined relatively movable supporting members carried thereby, a lazytong truss having adjacent bars fastened to said members, awning sections carried by the truss, and means on the sections engageable to limit the projection of the latter end of the truss.

7. An awning structure comprising a supportin bracket, having inclined arms, a hood over said bracket, an operating member journalled on one of said arms, awning sections, said sections and hood having coacting hook flanges for engagement to limit outward movement, inclined relatively movable supporting members carried by said arms, a lazytong truss having adjacent bars pivoted to said supporting members, brackets pivoted to joint members of the truss and carrying said sections, and a draw means connected to said operating member and one of the other parts to cause collapse of the structure when the latter member is operated. I

8. An extensible awning structure comprising a plurality of metal sections adapted to be collapsed one under the other, and a'lazytong truss connected to the respective sections for supporting the latter in either an extended or collapsed relation.

9. An extensible awning structure comprising a plurality of metal sections adapted to be collapsed one under the other, said sections being provided with hooks along their adjaeent edges and adapted to interengage. to retain the sections against outward movement when the sections are fully extended, and a lazytong truss connected to the respective sections for supporting the latter in either an extended or collapsed relation.-

In testimony whereof, we have hereunto subscribed our names.
