Application June 21, 1944, Serial No. 541,392

This invention relates to an adjustable Venetian blind typeof awning devised for outside use ad-l jacent Windows, porch openings, or similar locations. The awning embodies the use of a plurality of slats all pivotally supported in predetermined sequence, arranged to pivot upon their long axes, and the slats are connected for simultaneous angular adjustment producing a variation in the respective spaces between adjacent slats and also angular variations with respect to their supporting frame.

It is, therefore, one of the mainrobjects of the present invention to provide an adjustable awning having a plurality of slats disposed in predetermined relation with respect to each other and individually pivotally mounted upon parallel axes. Such an awning permits the passage of air for ventilation through the respective spaces between the slats and provides adjustable means connected with the slats to permit regulation thereof as to the entry of light into a window or space over which the awning is supported for the purpose of controlling light entry into a room under changing light conditions to suit the individual taste of the user.

With a conventional type of canvas awning thereis no provision whatever for the purpose of ventilation aside from the regular iiow of air which is not entirely blocked by the awning. Nor

cent windows the convenience and accessibility of doingsuch a thing has always presented a problem particularly when such blinds or awnings y were being attached to upper story windows.

Therefore, as to the ease of handling and attachment from the outside of a building of'a conventional type of awning the safety factor considera.-

tion has always been objectionable to the ordinary home owner. l

The present type of awning has been so constructed that the supports and theV entire framework thereof for carrying the individual slats is completely disassembled and may be secured to the exterior of a window frame from the interior of such window. This, therefore, presentsa notable advantage in an awning of this type, not only as to handling at the home or point of application, but also making possiblethe shipment of a complete awning of rthis nature in a very small package wherein all of the individual parts may be crated orrpacked for shipment. By the same token, the home owner or user of such an awn-` ing can easily disassemble such an awning in the fall of thev year and store it in a very small space over the winter. Theruser can retain the carton or crate in which the awning was shipped and may store the awning parts in such carton when disassembled necessitating only a relatively small storage space' for this purpose.

does the regular type of awning have 'any particu- 30 'The slats of the present awning are preferably lar feasible means for adjusting the same to 'meet varying light conditions. When a conventional type of awning is down and the day is cloudy with bright sunshine at intervals, such awning will either make the room 'too dark at the cloudy in- 35 tervals or if the same is raised it in ineiective in shielding the room against becoming too bright during the sunshine intervals. The awning of this invention can be easily and conveniently regulated to meet such varying light conditions as 40 will be self-evident from the description and dis',- closure to follow.

'A further feature of the present awning resides in the structural provision that when the blind slats are substantially in full closed position small spaces remain between the respective slats through which a person is capable of viewing the outside as contrasted with a solid canvas awning that entirely shuts oi such a view. Furthermore,

when the relatively thin slats are regulated to be 5 disposed approximately in horizontal planes they present a substantially free view with little interference to the sight of a person or persons within the room protected by such a blind.

' disposed in overlapping relationship. The object for this arrangement has been to produce better reflecting surfaces between adjacent slats and also for the purpose'of having the slats deilect rain under normal conditions. If the severity o the rainstorm is not too great the rain too rheavily windborne it is possible to maintain the upper window sash opened for ventilation while the slats of the awning are in their down position disposing such `slats in a manner for the rain to merely cascade therefrom, from one to the other ofthe slats and finally oi of the end of the awning protecting the window opening from rain entry. This presents a desirable advantage in the present awning as the latter permits a certain amount of ventilation on rainy dayswhen the humidity is extremely high and circulation of air within a. home is necessary and welcome.

There are other features and yadvantages in- Y In attaching exterior blinds or awnings adjay easily be disassembled for cleaning. and painting for cleaning or painting. Furthermore, the awn- I ing may be painted tosuit the general trim of a building or in contrast therewith depending upon I In this connection it the desired color scheme. may be stated that this awning can be constructed of practically any suitable material that is feasible for this particular'use although `the same y has been preferably constructed of comparatively in` expensive wood.

A pair'of braces I'I and I8 have drilled Y ends for fitting over and being slidably connected with therrod I4.

The framework of the awning is secured to a Window sash by securing hooks 20 to the sash as illustrated in Figs. 2 and 3 and by hooking rod I3 over the same for the purpose of supporting the framework. -The braces VII` and I8 are also vertically-drilled as at 2l Vfor hooking upon L- hooks 22 illustrated in Figs. 2 and 3.

It is to be noted that the upper ends ofthe arms are shaped in a specific manner to permit the installation of the framework and also to maintain the same against dislodgement after the same has been installed. This is accomplished by providing predetermined clearance between hooks y2l) and the upper edge 23 of the top of the window sash as indicated in Fig. 3, the arms being constructed with a at end surface 24 located acertain distance from the openings in the arms y for receiving the V`1. 1p) oerrod AI3 and by. providing a relatively sharp corner at the outer edgeof the arm; p t

The" awning is installedby placing 'therthree arms Ii), YIl and I2V upon the'rods I3 and ifi to'- gether with braces I'Iand I8 'on rod I4 and guide ing this unit" through the upper" lowered sash opening of'ar window tosupport'the same invertical position upon'thev hooks 2i); The awning rod I3 is passed over the top'outer end of thehooks whilethe arms' I0; `I I 'and I2 are maintained substantially in verticalposition.' This permits sufficient clearance between' the outer end 26 of the hook Zil'and the surface of the upper wall 23 `of thewindow sash'to allowthe rod I3 to clear Then by swinging the the end ofthe hook' 2S. arms outwardly. and placing the apertured'ends ofthe braces lIIfandl i3 over theL-l'looks 22, the Vhigh pointsZE ofthe arms It,l II and I2'are brought intoZ verticaljalignment abovethe rod I3. Sincethe distance from the top of the'point 25 to the rod I3 is greater' .than the distance from rod 'I3 to the flate'nd 24'it 'is impossible 'for the lawlfl ing tobecome dislodged under wind actionV or through, other'accidental lifting' inasmuch as rod I3 cannot now clear the' ends 25 of the' hooks 2li.V Thus, the awning isl locked 'in place with the simple window connections provided therefor.

" With the bracesl'l and I3 located kwithin the confines of the outer' arms Ill and I2 as' illustrated in Fig. 4, itis possible tohave the par'- ticular size of awning'illustratedv t a'number Yof window'sizes lessthan the distance between the outer arms by cutting the' rods to suit. However, should the window frame size be greater or rod Iii only if desired; which will extend out- 'holes'at their ends for the reception'of 'connecting .if

The ap'in ll5A is screwed O1' 'jsuch `as -I5 of a lengthrsubstantially' equal Wardly from 'the sidearms'l and I2 as indicated in dotted 'lines inFig.' 4, in Which-case the' arms Il and I8 maybe placed' outwardly .from the two outer arms I6) and I2 permitting the useof the Y same size awning in connection with window widths of greater size than could bei accommodated'with the braces between the arms liland I2. 'This' of course must take place 'within prac'- tical limitations;

It has'been found from practice thatQro'ds I3 land I4 need no-tV be secured to tloearms Il),v` I Il and I2 yand preferably the holesbored into these arms mayfbe'of a tight tto Vhold 'the rods in place relative to the arms.` Furthermore, theup; per rod I3 is normally confined/within the laterally Spa'ced sides of, the: windowopeningvas illustrated irrFig.v 2 and 'therefore cannot move laterally with respect to the supportingqarms if said rod is made to fit such opening. The outer rod or. lower rod I4 is further held in place by thertwo braces'I'I and I8 which are also frictionally carried upon the same and it is highly improbable that this rod will move laterallywith respect to the framework. Such rods, however, maybe secured by suitablemeans if desired, de-

pending upon thefmaterials used and the requirements of `the installation.

A plurality of Vslats 30 are supported upon the arms I0, II and I2, to complete the awning assembly and to 'provide the adjustable means whereby the user can shut y,out or permit the entry ofl exterior lighi-l to' suit the individual taste. These slats 30 may be constructed of any suitable material. Ihe preferred formvutilizes ordinary drop siding which has been found very satisfactory as well as being of low cost in the fabrication of such awnings;

Each of the slats'30 is provided with 'a plurality of slots 3| equal in number to the number of arms used in the framework, and cross wires 32 are suitably secured to the slats to span each of the slots 3I in a predetermined position. rIhe arms I0, II and I2 have been notched as at 33 for the reception of the wires 32 for each of the individual slats. The wires 32 of each slat are aligned and parallel to thelongitudinal dimension of the slats while each of the notches 33 in the arms are also positioned in definite spaced relation with respect to each adjacent .notch as well as being in predetermined aligned krelation with respect to the length of the awning whereby all ci the respective slatsv are pivotally supported as illustrated in Figs. 1 and 2. Likewise, as illustrated in Fig. 2 it is to be noted'that the spacing of the slots 33 .is such that the slats are all overlapping as shown in Fig. 2` vto produce the rain shielding relationship and a` better light shielding arrangement. Y

The framework when connected with the sus-r pending hooks 20 and while still hanging in vertical position 'against the window provides a rack uponl which -the individual slats may be connected from the interior of the Window by the person installing `the same. Each slat `is individually handled and pushed through the window,vmoved into horizontal alignment with one of the aligned sets ofnotches 33 and dropped into place with the pivotal wires 32 nesting within such notches 33 of the arms.

As illustrated in Figs. -3 and 5, oneof the wires 32 isextended to form a leg or depending arm 34 and is conveniently bent back upon itself to provide a pivotal portion 35 coincident with an axis parallel to the axes of the wires 32, and the end of this wire is bent as at 36 toform a retaining hook. All of these legs or arms 34 Yextend downwardly and are adapted to be connected'by an actuating` link or rod 31 having a plurality'of loops 33 located at spaced intervals equidistant and coincident with the plurality of` depending arms34 connected with the yrespective slats 30. Whenall of the slats have been suspended in their locationsnpon the frameworkof the awn-v ing, the actuator loops 38 are dropped over the ends-of the hooks 3E and rotated 90 degrees to position the actuator link with the loops 38 thereof in acommon vertical plane as best seen in Figs. 3 and 6, This substantially completes the assembly of the awning which has all been acyof the armsIO to I2.

moving the'two braces II and I8 outwardly, to swing the. awning structure upon the upper'rod I3' as a pivotal means and then dropping the.

cord hook 4I, see Fig. 2, placed at an accessiblev By pulling A point for the use of an operator. cord 40, the actuating link 3'I is moved relatively to the stationary frame arms III, II and I2, the

' link transmitting such motion to the other pivotal partsV 35 of the arms 34 of each ofthe slats 30 whereby each slat is pivotally actuated .to

cause all of the slats to move in synchronism upon their pivotal supporting wires 32 with respect to the'stationary arms I0, II and I2. The slats can be moved through a, relatively wide angular range and in Fig. 3 slats 30 have been shown in full lines in one of the angularly adjus/ted positions and indotted lines in a relatively wide. open position. Cord 40 also acts to hold the actuator 38 inplace upon the respective pivotal parts 35 as best shown in Fig. 6.

Obviously, various light reflections may be obtained directly from the'slats per Se by providing an adjustment whereby direct light may be admitted at certain angular positions to be reilected by the slats individually. 'I'he slats can also be adjusted to admit light directly between the slats. f

In thisccnnectionit may be said that the slats could also be made of a transparent nature depending solely upon the light reflecting properties thereof orelse they may be made with onev surface dull and the other surface shiny or in` anycombination thereof to produce certain'light reilecting-qualities that may be used to enhance an awning of this type to increase the utility thereofv under a wide range of conditions and per- Y sonal requirements. I

Referring back to Figs. 4 and 7, it is to be noted that each slat is prevented from endwiseshifting by means of the slots 3| which straddle the sides of the arms I0, II and I2. 'Also, as shown in Fig.

7, the bottoms 42 of the Slots 3I canbe variedas to angularity and shape to produce certain del-l nite positions at which the respective slats may be maintained indenite angular relations with respect to the supporting arms I0, II and I2. Fig.7 shows the bottom or inner surfaces 42 of the slots 3 I- as made to rest upon the upper faces 43 of each Furthermore, the angularity of the notches 33 are preferably made to incline either to one direction or the other of a vertical plane to` subject the wire mountings 32 of each of the slats 30 to frictional resistance in the eventV that wind will tend to lift the slatsl off of the arms. Ordinarily it is the connector or actuating, link 31 which together with the cord 40 maintains all of the slats in their nested pivotal relations with respect to thesupporting arms I0,

Furthermore, the slats are all rela` complished with the awning frame hanging ver tically outside of the windowk andl within easy` reahfrqm .theinteronof the roomY By finally tively flexible and can stand considerable abuse, practice having proven that the same maybe together 'at the point of contact of such object and straightening out again after being subjected to such; shock.
