AWNING SHUTTER Filed May 21, 1958 2 Sheets-Sheet l INVENTOR. ANDREW SWANFELDT g w Vazzz A TTORNEY.
Patented Mar. 11, 1941 UNITED. STATES PATENT OFFICE 6 Claims.
This invention relates to awning shutters, and more specifically to devices which may be used selectively as either awnings or shutters for outside doors and windows or other openings in thev outer walls of buildings. The utility of the conventional fabric awning is ordinarily limited to the provision of shade for the opening over which it is disposed and the deflection of rain during mild storms. In the art prior to my invention such awnings have been found to be objectionable in many instances because of their susceptibility to damage by wind and storms, and further, in that they tend to shut out light as well as the elements from which they are intended to afford protection. In many communities which are frequented by severe wind storms, it is necessary to remove the awnings and install shutters for the additional protection furnished thereby.
It is an .object of this invention to provide a device having adjustments permitting its utility as either an awning or shutter, and thereby obviate the aforementioned disadvantages.
More particularly, a primary object is the provision of a device of the character described having a plurality of parallel louvers carried by a frame pivoted to the upper edge or the jamb of a window or like opening, the louvers being pivoted in parallelism to close the area between the sides of the frame or, selectively, to vary the angular adjustment of the louvers to reflect particular rays of light passing between the sides of the frame without diverting the passage of air or of light received from a different angle.
Another and highly important object hereof is the provision of mechanism for the Joint pivotal control of the disposition of the louvers, which is conductive to facile manipulation and positive operation.
Another object is to provide a translucent awning affording a partial shade for a window or like opening adapted to carry difierent designs or colors on opposite sides so as to harmonize with both architecture or color schemes of the exterior of the building and of the particular room in which the window is located, respectively.
Other objects and corresponding advantages, such for example, as durability, comparative economy in manufacture and assembly, ease of installation, and an attractive appearance, will be apparent to those of skill in the art upon an examination of the following description read in the light of the accompanying drawings, in which:
Fig. 1 is afront elevation oi a window structure and my invention, operatively associated therewith;
Fig. 2 is a sectional view taken on lines 2-! of Fig. 1, illustrating particularly the means for controlling pivotal disposition of the louvers;
Fig. 3 is a sectional view taken on lines 3-3 of Fig, 1;
Fig. 4 is a section on lines 4-4 of Fig. 2;
Fig. 5 is a detailed broken elevation of the pivotal attachment of the louver-carrying frame to the outside top rail lining of the window casement;
Figs. Sand 7 are sectional views taken with correspondingly numbered lines of Figs. 2 and 1, respectively; and
Fig. 8 is' a section on lines 8-8 of Fig. 5.
Referring to the drawings in detail, the numerals of which indicate similar parts throughout the several views, Ill designates generally a window casement comprising a top rail II and outside lining I2, a sill l3 and runways l4 for the sliding sash in which panes iii are carried. A horizontal pivot post I6 is journalled in hinge brackets I] attached to the lower edge of the outside lining I! or the window top rail. 0n the opposite ends of the post l6, one end of each of a pair of channel irons l8 and i9 is pivotally secured, so as to extend at right angles thereto and form, respectively, the opposite sides of an awning frame 20. The outer ends of the channel irons are connected by means of an angle iron 2| to reinforce the parallel position of the channel irons and the rigidity of the frame.
It will be apparent that frame 20 will normally gravitate to a vertical position, being pivotally suspended at one end from the top of the window casement, but may be swung on the pivot post ii to form any desired angle with the plane of the window.
When the device is in use as an awning the lower end or the frame is normally held from the window a distance predetermined as most favorable for that purpose by a pair of props 22, which are pivoted at their outer ends to respective channel irons at a point intermediate the ends thereof. The opposite end of each prop 22 is releasably attached to one of a pair of brackets 23, connected to the sash at each side of the window by means of a pin 24 which extends through the brackets and a hole in the end of the prop. While only a single pair of brackets 23 are illustrated, it will be apparent that a plurality may be disposed in vertical alignment at each side of the window with which the props may be selectively associated, in the manner described, to maintain the frame at any angle with respect to the window and the sun's rays.
A plurality of horizontal rods 26 are pivotally supported equi-spaced apart and parallel to the angle iron 2i in frame 26, the opposite ends of each rod being Journalled in aligned holes formed in, the outer sides of the respective channel irons, the inner side of each iron being cut away as at 25 (Fi The length of each rod 25 intermediate the channel irons is squared for the purpose about to be described. A louver 26 (later described in detail) of a width greater than the distance between the respective rods 25 is rigidly secured to each rod by a pair of attaching members 21 riveted or otherwise secured to the underside of louver 26 at points thereon overhanging respective channel irons and extending transverse to the rods, each member 21 having one of its ends turned over the edge of the louver as at 28 to resist relative displacement of the louvers and rods. Integrally formed with and on the underside of each member 21 is a lug 29 having a square hole therein through which a rod 25 extends. to preventrelative rotation therebetween.
The louvers are composed of a translucent plastic. The underside of the louvers are adapted to be colored to harmonize with the colors used for the interior of the particular room over the window of which the awning is employed, while the upper surface of the awning may be of a different color, as, for example, corresponding to the color of the other awnings on the building.
The mechanism for maintaining the parallel disposition of the louvers and for controlling their position relative to the frame comprises a gear rack 30 slidably disposed in one channel Hi. The lugs 29 secured to each member which overhangs channel iron l8 are semi-circular and are provided with a series' of teeth 3| which are held in mesh with the teeth of rack 30, whereby longitudinal movement of the rack will cause arcuate movement of the lugs carrying teeth 3| and the louvers attached thereto as is hereinafter more in detail described. An elongated opening 32 is formed in the bottom of the channel iron i8 in which the rack is disposed adjacent the end thereof pivoted to the top of the rail lining i2. Through opening 32, a short gear rack 33 extends, which is integrally formed with the underside of the gear rack 30.- A gear housing 34 encloses rack 33, being secured by rivets or the like to the underside of channel iron i6. A pinion 35 journalled on a pin 350, secured to one wall of the housing, is held in mesh with rack 33 to reciprocate the same. Pinion 35 is rotated by a worm gear 36 carried rigidly on a shaft 31. Shaft 3'I is in turn journalled in walls of housing 34 which are parallel to the window and extends through the housing to a point adjacent the window. A handle 38 on the end of shaft31 facilitates manual rotation of the shaft and the adjustment of the louvers.
It will thus be seen that I have provided an awning comprising a plurality of louvers 26 normally held in a position overhanging a window or like opening in a building, but adapted for movement to a position substantially closing the opening as a protection against the sun, wind, rain, or other weather conditions, and which incorporates therewith mechanism for tilting the louvers to cause their separation and thereby aasg'na It will be understood that the embodimentherein disclosed is only illustrative; that modiilcations varying as to size, number, proportion and shape of the parts may be made, particularly as to the length of the frame withrespect to the length of the window and as to the number or width of the louvers; that the frame may be attached rigidly or adjustably to any portion of the window sash; all without departing from the spirit of my invention as defined by the appended claims.
