v This'` invention relates to sun shades and awryings' for windows 'and' doors and it has particular referencetoy fol'dable or collapsible awnings.

. The principal object of the invention is to Vnrovide an awning of neat and attractive design, con.- structed preferably of sheet metal in collapsible sections, the latter beingv fso related,l when in extended position that they will exclude'all direct lrays of the; sun yet will admit indirect light as well asY air, to dispel. or release heated air tend ing to accumulate under unventilated awnings. Moreover, the relativespacing but overlapping're lationship of the awning'` sections precludes passage of rainwater while Ventilating the: area be heath the awning.

Another object of the invention isto provide a sectional ventilated awnin-g in which the sections are normally under a tensional force urging them to extended or open position, to resist which', 'a .pull cord is provided to closelorcollapse theawning sections, having an operator manipulatable -interiorly of the building on which the awning is installed.v Still another object of the invention is to provide an awning whoseparts are so designed that they lmay .berireadi-ly assembled and disassembled ,for convenient packing and.A shipping and among the parts is a novel form of flashing designed to provide a watertightseal between the awning and its mounting surface.

With the foregoing objects in view, the invention. has iurther reference to certain ieaturesof accomplishment which will become apparent as the description proceeds, taken in connection with the accompanying drawing wherein: K

Figure 6 is a fragmentary sectional View of the awning showing the Ventilating spaces between the awning sections which also admit indirect light and further illustrating the stops for predetermining overlapped relationship of the sections, and

Figure 7- is* a fragmentary perspective view of one of the awning sections.

Sheet metal awnings in collapsible sections are not broadly new, nor it is considered herein to-be new to operate an awning interiorly of the building on which it is installed, but it is considered an improvement in this art to so arrangethe sections of the folding type of awning in su'ch mannerthat entrapment of heated air beneath the awning is avoided, thus contributing much towards the comfort of occupants of the build ing.` It is considered also a further advancement in' the art relating to collapsible metal awnings to provide for the entrance of indirectl light while prohibiting passage of rainwater so that the interior of the room protected by the awning will not be unduly darkened, even on days when the Sun is shining..

Continuing with a more detailed description of the drawing, reference numeral Ill denotes a stationary hood or mounting section having a longitudinally formed flashing plate l l thereon, the latter in. turn,. being provided with longitudinal channel. lf2 adopted to contain a suitable weatherprooiing compound I3 which seals the upper porition of the,` mounting section against passage of moisture between the same and the wall I4 to Which it is attached by screws I5.

The awning is designed to be dismounted Afor convenient packing and shipping and with this in view, a joint I6 such as shown in Figure 3, is provided for attaching the awning section Hl to fa substantially' triangular side member l1, the

parts being held together by means of metal screws I8.k This is true also of the several movable sections which are telescopically related and adapted to be foldable under the stationary section i0, hence the same reference characters are employed to indicate the joints. and retaining screwsthroughout.

The movable sections of the awning include a section I9 and `its triangular side members 20 and an outer section 2l and its complementary side members 22. It is to be understood that as many awning. sections as may be required or de scribed may be incorporated in the awning but in any event, the lower ends of the side members 2D and 22 on each side are mounted on a common pivot 23 situated in the lower end of the side member I1 of the stationary mounting section, the said member I1 having a ange 24 thereon which is secured by means of screws 25 to the Wall I 4.

capable of being folded one into the other as they are successively raised. This is accomplished by means of a cable 26 adapted to be wound on a spool 21 and which extends upwardly alongside the window frame 28 and through an eyelet 29` at the top of the frame, thence through a second eyelet 30 at the opposite side of the frame, whereupon it extends outwardly and is attached at 3| to the lowermost awning section 2i, as shown in Figures 1 and 2. Another length of cable 32 isattached to cable 29 at a point below the eyelet 29 at one end and has its opposite end attached at 33 to the opposite end of the lower awning section 2l. Thus, by pulling upon the cable 2S as by winding the same on the spool 1 21, the lower section 2l is raised to aposition within the next section I9, followed by the latter section which disposes both or all of the movable sections underneath the stationary section i0.

Returning to the operating means for the cable 25, the spool 21 on which it is wound is mounted on a shaft 34 (Fig. l) which extends axially into a hollow shaft 35, the latter extending through an opening made in the wall 14 and carries a crank 36 on its interior end. A clutch consisting ofa boss 31 is mounted on and rotated by the hollow shaft which is adapted to enter a hole (not shown) in one side of the spool 21 to rotate the latter in raising the awning sections. A

spring 39 within the hollow shaft 35 normally exerts a force tending to separate the boss 31 and spool 21 to disengage the clutch. To engage the clutch, the crank 36 is forced inwardly against the resistance of spring 39.

The awning sections I9 and 2l are normally urged to open or extended position by means of a looped or torsion spring 40 (Fig. 5)., one end of which is affixed by means of a screw 4| to the wall I4 while the opposite end is secured by a screw 42 to an internal flange 43 formed along one edge of the side member 22 of the lower awning section 2l. The tension of the spring 40 resists raising of the awning sections, tending to maintain them in extended position and has the -further eiect to prevent relative movement of the sections by the wind, hence rattling thereof is minimized or eliminated entirely.

In order that an air pocket beneath the awning ywill be avoided when the sections thereof are extended, there is provided between these sections an intervening space 44 better shown in Figure 6. The forward edge of each awning sections overlaps the rear edge of the next adjacent section but is out of contiguity therewith to admit indirect light yet exclude rainwater. Direct rays .of .the sun on the exposed part of one of the -sections will be reflected by the underside of the overlying portion of an upper section and through the window protected by the awning, thereby dis'- pelling the darkness which would otherwise exist inthe room.

To provide the light admitting and Ventilating openings 44 and yet insure relative engagement of the awning sections for successive raising and lowering thereof, the forward edge of each sec- 4 tion is turned under as at 45 (Fig. 6) to lie flush against the underside of the section. This undervturned portion not only reinforces the forward "edge of the section but from this portion is struck a projection 46 at each end against which abuts a similar projection 41 which is struck from an underturned portion 48 on and longitudinally of the next adjacent and lower awning section. The portion 48 also reinforces the rear edge of each movable section. Therefore, between the downwardly and upwardly turned protuberances 46 and 41 respectively, there is an elongated space l44 through which -air and light may pass but, in view of the overlapping relationship of the front and rear edges of juxtapositioned sections, there is little likelihood of rainwater entering the opening 44 except possibly during a wind of hurricane proportions in which case the awning will more than--likely be raised or the `window closed.

Manifestly, the construction a shown and described is capable of some modification and such modification as may be construed to fall within the scope and meaning of the appended claim is also considered to be within the spirit and intent of the invention.

What is claimed is: v

In a sheet metal awning, the combination comprising a stationary mounting section and a plurality of movable sections successively disposed under said stationary section, all but the stationary of said sections having both its forward and rearward portions turned inwardly to lie against the undersurface of the section, a protuberance depending at right angles from each end of the inner edge of the inwardly turned for# ward portions of said awning sections, a complementary protuberance extending upwardly at right angles from each end of the rearward portion of each of said movable sections and adapted to lie in the path of `said first mentioned protuberances to engage ,therewith and to limit the degree of relative extension of said movable sections, substantially triangular side member on each of said awning sections, the side members of each side of said awning having a common pivotal point and spring means for imposing ten#- sion on said :awning sections in extended position thereof.
