VENTILATING WINDOW SHADE Filed Mdrch 5, 1931 7 Q 7 lNYEN %5 4 M I ATTORNEYS Patented Mar. 15, 1932 PATENT OFFICE" LOUIS A. BOSS, 015 NEWARK, NEW JERSEY VENTILATING WINDOW SHADE Application filed March 5,

This invention'relates in general to window shades, and more particularly to window shades which are mounted upon springoperated rollers.

One Object of the invention is to provide a window shade embodying novel and improved features of construction whereby air may pass through the shadefor ventilating purposes and so as to avoid rattlingor flapping of the shade when it is drawn'over a partially open window.

Another object is to provide a window shade of this character having a plurality of openings therethrough to permit the passage 1 of air to and from a room through a window to which the shade is applied, and novel and improved means for concealing the openings and directing incoming air downwardly from the openings.

Other objects are to provide such a window shade having one or more horizontal rows of openings and a flap or closure secured to the side of the shade which faces into the room when the shade is applied to a window, said flap being movable relatively to the shade to permit ingress and egress of air through the openings; to provide a novel and improved form of flap or closure for the openings in the shade; to provide such a shade which shall be simple and inexpensive in construction and which shall in no way hinder rolling and unrolling of the shade upon the spring roller, and to obtain other advantages and results as will be brought out in the following description.

Referring to the accompanying drawings, in which corresponding and like parts are designated throughout the several views by the same reference characters,

Figure 1 is an inside elevation of a window having a shade embodying my invention applied thereto and shown in operation;

Figure 2 is a transverse vertical sectional view through the shade showing the flap or closure for the opening partially closed;

Figure 3 is a similar view showing the flap in open position;

Figure 4 is a horizontal sectional view, on the line 4-4 of Figure 2;

Figure 5 is a similar view, on the line 55 of Figure 3, and p w Figure 6 is a view similar to Figure 1' showing a modified form of the invention. 7

Specifically describing the embodiment of the invention illustrated in Figures 1 to 5, inclusive, the reference character A designates a window frame of known construction which has a known type of-shade rollerl journaled at the top and on the inside thereof. Mounted upon this roller in the usual way is a window shade 2 which has a plurality of horizontal rows of openings 3 therein which are disposed longitudinally of the shade so as to be located at a point adjacent the top of the window when the shade is fully drawn over the window, as shown' in Figure 1 of the drawings. 7 r V Mounted on the inside of the shade to overlie and conceal said openings 3 is a flap or closure 4 formed of suitable ffiexible material. This flap is secured at one edge to the shade above the openings 3 in any suitable manner as by a line of stitching 5, and the lower edge of the flap is free from the shade. The flap also includes flexible or somewhat resilient end walls 6 which are preferably integral with the body of the flap and are secured at one edge to the shade at the sides thereof, as indicated at 7. These end walls are approximately triangular in shape, and are folded substantially midway of their length, as at 8, so as to collapse flat against the shade beneath the main portion of the flap, as shown inFigures 1 and 2 of the drawings,or to unfold outwardly as the main por tion of the flap moves away from the shade, as shown in Figure 3 of the drawings. These end walls serve to securely connect the flap to the shade and to limit outward swinging of the flap away from the shade. They also tend to hold the main portion of the flap in slightly spacedrelation to the shade to permit' passage of air through theopenings 3 at all times, and restrain flying and rattling of the flap.

With this construction, it will be observed that when the shade is fully drawn over the window, the flap 4 faces inwardly of the room and entirely conceals the openings prevent flapping or rattling of theshade.

Outgoing drafts of air may pass upwardly between the flap and the shade through the openings 3. The upper end of the flap being secured to the shade and the lower edge being free, the flap inclines downwardly from the shade and directs currents'of air downwardly. When the shade is rolled upwardly on the roller, the end walls 6 fold or collapse toward the shade beneath the main portion of the flap, as shown in Figures 1 and 2 of the drawings, so that the flap causes no hindrance to the rolling of the shade.

V A. modification of the invention is shown 'I in Figure 6 of the drawings where a shade 9; lower edge away from the shade so as to perroller 9 is connected to the lower end of the window frame and the shade is drawn over the window toward the upper end. lVith this form of the invention the openings 10 corresponding to the openings 3 are formed adjacent the free end of the shade so as to belocated at the top of the window when the shade is drawn. Over these openings 10 issecured to the shade a flap 11 identical in construction with the flap 4 shown in Figures 1 to 5, inclusive. 'The construction and operation of this form of the invention is other wise the same as that hereinbefore described.

It will be observed that in both forms of the invention, due to the cover flap being on the inside of the shade and the bending of the flap as the shade is wound on the roller, the flap will'normally tend to swing at its mit free passage of air outwardly through the openings.

While 'I have'shownand described the invention as embodied in certain details of con- I struction, it should be understod that this is primarily for the purpose of illustrating the principles of the invention, and that many modificationsand changes may be made by.

those skilled in the art in thedetails of construction of the invention without departing from the spirit or scope thereof. I am aware of Patents No. 618,4A1, dated January 31,

openings therethrough for passage of air, a cover flap for said openings secured at one edge transverse of the shade, the other edge of said flap being free, and means for securing the ends of the flap to the shade to induce and limit movement of said cover flap away from the shade so as toadmit air through. said openings and prevent complete uncovering of said o-pening by the flap.

2. A window shade having a plurality of openings therethrough for passage of air, a cover flap for said openings having a main portion to overlie said openings and secured at one edge transversely of the shade, and walls at the ends ofsai'd main portion secured to said shade foldable beneath the flap and tending normally to swing said flap away from. the shade, whereby movement of said flap away from the shade is permitted by extension of said end walls to admit air through said openings, said movement of the flap is limited by said end walls, and said end walls may fold between said main portion and said shade to permit movement of the flap toward 1899, and No. 1,630,344, dated May 31, 1927,

and do not desire to be understood as attempting to claim constructions such as those shown thereby. Obviously, the ventilating openings and flap closure also may be arranged onthe shade so as tobe located at the bottom of the window when the shade is drawn, and the transverse edge of the flap may be secured to the shade below the openings instead of above-the openings; 7

Having thus described the invention, what I claim is:

1. A window shade having a plurality of
