.My invention ,relates to sheet metal awnings of the -ventilatng type wherein horizontally disposed sheet metal slats or stri-ps are spacedlv disposed in parallel relation :for :admitting air circulation therebetwcenand for simultaneously excluding direct rays :of the sun.
The invention lmore particularly relates to =slatted awnings ,ci the hood-type,v wherein the sheet metal slats are rigidly mounted, in contreedistinctionfto the adjustable lower-type .awnings-wherein the slats are permitted pivotalmove- .ment upon their A.own -'longitudinal axes.
.Inrmost sheetmeta-l slatted :awnings :of the hoody,ty-pe, the suns rays ,stri-king the upper surfaces of -the sla-t5, :are reiiected 4oil ,said suriacesdirectly ,tuto the building opening or window between the inner edge J.portions fof the slats.
it is therefore necessary for the kdesigners of such awnings, in order to defeat such ,reectiom to dispose the slats at a comparatively steep angle with .relation :to the vertical, vand to mount them i. y Inlose together.
The principalfobjectof the present invention, .is vto sc design, ,or form, the :sheet metal slats, 4that the directly reilected raysgarie excluded :from entering the window..
Another principal object of the invention Vis to .so :.deiorrn the upper surface ofeachs-lat, that diy.neet ieirection of the rays is .broken up and .dif-
used `before the rays are permitted to enter the window.
`The combined result ,of .such design, and such deformation, is to prevent glare when Ia person within the groom looks 'toward the window. The combined object, therefore, is to obtain a, well lighted room, yet .one .in which window glare is eliminated.
' 'The present invention allows substantially all of the reflected sun rays to enter the room, but prevents their eri-tryV `until 'after 'they have been diiiused. The slat structure also extracts heat from A:the suns rays during yeach successive difitusion or reflection thereof.
A furtherfobject is to provide an awning of Vthis type, which will not only accomplish the desired light ray diilusion, but one which may be manufactured at a reasonable cost.
Other objects will be apparent from the following description when taken in conjunction with the accompanying two sheets of drawings, wherein:
Figure 1 is a perspective view rof a hood-type awning made in accordance with the present invention, a portion being broken away to disclose construction.
2 ligu-re 2 is a vertical sectional View taken sub:- f tally along the line 2 2 of Figure l;
ure :3 is an enlarged vertical sectional view :illustrating the relationship of three of the slats, .and diagrarninaticallgy illustrating the light freflection and diffusion; and,
Figuree is an enlarged vfragmenta-Iy Perspective view of a sheet metal slat in which a :dii- .i-erent ,embodiment of the surface deformations has been used.
.Like rchareuiters .of reference designate like parte in those heures wherein they occur.
ln the drawings:
The .re-ference numeral i :indicates a :plurality `ci downwardly and outwardly sloping stringere or joists which .are parallel with :each .other and which have their upper Yends rigidly connected :to
vra horizontal member 2 which is vadapted to :b e
attached to a building wall ,above a window therein. ,One :of the .stringere 4'is provided at each end of the member 2, and as many are s-pacedy ,positioned therebetween as is necessary to accom- Amodate the width .of the window Aopening aboye which the member 2 is .to be installed. The lower ends -oi the stringers l are all rigidly .connected sheet metal slats or strips .5.
The slats 5 are identical with each other, and each vhas a co-extensive integral upper flange ,portion i3 which .lies iiatly upon the :stringers i, and all of which ilanges are rigidly connected @to the stringers. Suitable rivets i .are preferably used for this purpose.
As best illustrated in Fig. 3, the `*major tions of the slats 5 are each provided with a series oi' longitudinally extending parallel :upwardly projecting deformations, corrugations, or zribsg,
and .theeatrenie flipper edge portion of eachflange 6 is provided with at least one elongated deforman tion 9 which is similar to the deformations 8.
In Fig. 3 is illustrated by dash-lines and heavy arrows two problematical paths in which the suns' rays may travel before they enter a window through the open space between the slats 5.
In following the possible path of light rays illustrated by the lowermost dash-lines, and by the heavy arrows l0, it may be seen that when the rays strike the fiat portion Il of the lowermost slat, which portion lies above the uppertherefore their brightness has been diminished before they leave the second slat 5 in their travel toward the window. i 1
Another possible path of the rays is shown In said Fig. 3, and is illustrated by the dash-lines accompanied by the heavy arrows I2.v
In this second instance, the rays are shown as rst being projected against the deformations of the next to the bottom, or middle slat 5.A Rays so projected are turned upwardly by the lowermost faces of the deformations 8, and are reected in a direction in which they reach the nether deformed surface of the next slat thereabove.- These latter deformations, on the upper- .smost slat 5, again bend the-rays to direct them toward the window, over the upper edge of the i next slat 5 therebelow.
In the present instance, as pointed out above with relation to the rst example, the rays are -all bent, scattered, or diifused at least twice before they travel toward the window.
f f It is thought to be obvious from the above description, that the particular formation of the slats 5, including the deformations 8, the flanges '5, the deformations 9, and the at portions II,
reaches a light ray deilecting and diffusing result `which prevents directly reflected rays from entering a window equipped with the awning. It is `also obvious that an awning constructed of slats so formed, causes the rays to be bent and diffused at least twice before they reach the lwindow.
In Fig. 4 is shown fragment of a slat 5 which in general cross-sectional `configuration is substantially the same as the slats of Fig. 3. How- Lever, in this embodiment of the slat, instead of the rib-like deformations 8, the major portion of the slat is provided with longitudinally extending rows of rounded bumps, pimples or nodules I3 are provided on its upper surface, and similarly v"arranged dimples or rounded indentations I4 lwhich are formed in the nether surface of the slat.V
In this latter embodiment, the upper surface ofA the upper portion of the ange 6 is formed :with a row of nodules I5, and the lower surface thereof is equipped with similarly arranged dimlples I6.
`In this embodiment it is preferable that the nodules I3 and dimples I4 of each row be stag.. -gfered in relation to those of the next adjacent row.
n The light diffusing effect-of this embodiment yis somewhat similar to that obtained in the rst embodiment, except that greater diifusion is ob- 4 tained from the multiplicity of rounded reflecting surfaces of the deformations 8 and 9.
It is obvious that the invention could well be embodied in forms other than the specic one shown in the drawing and described hereinn without defeating its practicability, and I therefore do not wish to be limited to specific structure further than I am limited by the scope of the appended claims.
