Dec. l0, 1935. o. P. cADMUs VENTILATING WINDOW SHADE Filed Nov. 1'7, 1954 7L? 70 75 lNvENToR Oscar? Oczdmw ma@ l ATTORN EYS Patented Dec. 10, 1935 UNITED STATES PATENT lOFFICE 4 Claims.
This invention relates to a window shade which is designed and adapted for shading disposition, or to be drawn down in relation to the window opening, yet admitting air therethrough to a room or apartment, when a sash of the window is in an open or partly open position.
The invention consists of the features hereinafter described by which a window shade will serve as a ventilator and at the same time give an ornamental appearance to the shade.
The nature of the invention and its distinguishing features and advantages will appear when the following specification is read in connection with the accompanying drawing, in which Fig. 1 is an inside View of a window, showing a roller shade embodying the invention arranged in the window opening, the lower sash being I'shown raised to admit air which passes through the shade, a portion of the shade being broken away to show the raised sash.
Fig. 2 is an enlarged inside view of a portion of the shade showing more clearly certain features of the Ventilating means.
Fig. 3 is an enlarged section on the line 3-3 of Fig. 2.
Fig. 4 is an enlarged section on the line 4-4 of Fig. 2.
Figs. 5 and 6 are views similar to Fig. 2 showing modifications.
On reference to Figs. l to 4 inclusive, it will be apparent that there is shown a shade I which is made of suitable material, such as oil opaque cambric or other cloth; the shade being wound on and unwound from the usual spring roller I I mounted in the frame of a Window I2 at the head rail thereof. The shade I0 is thus mounted for shading disposition, o-r to be drawn down in relation to the Window opening, as shown in Fig. l. The shade has the usual pull slat in a hem on the lower end thereof.
In accordance with the invention the shade I0 has an apertured area for the passage of air therethrough, and means to cover the apertured area, but without preventing the passage of the air through said area. In the present instance the apertured area is at the lower end of the shade I0, and consists in the provision of a plurality of apertures I3 in the shade. The apertures may be of any shape, and are arranged in spaced rows transversely of the shade. There are five rows of apertures in the present instance, but any number of rows may be provided. The means for covering the apertured area in the present instance consists of strips I4 of the same material as that of the shade, there being one strip I4 for each row of apertures I3. The strips I4 are secured to the shade on the inside thereof by lines of stitching I and I 5 respectively, occurring at the top and opposite ends of the apertures, and leaving the lower edges of the strips I4 unsecured. 5 Due to the flexible nature of the strips they may be distended as shown in Fig. 3, thereby permitting air to pass through the apertures I3. The air will be deflected downwardly by the strips, and for this reason serve as deflectors or baffles. The strips are scalloped to conform to the shape of the apertures and give an ornamental appearance. It is obvious that the strips will not interfere with the rolling or winding of the shade because of their flexible nature.
In Figs. 5 and 6 there are shown variations in the shapes of the apertures and strips, to indicate that various ornamental effects may be obtained within the invention, aside from providing desired ventilation. 2O
From the foregoing it will be understood that when the shade having the features described is down in a shading disposition, with the lower window sash raised, as shown in Fig. 1, an amount of fresh air, greater than the amount ordinarily admitted, is permitted to ow into a room or apartment, by reason of the apertures I3, while the appearance of the shade is embellished by reason of the apertures and strips.
1. A window shade having a plurality of apertures for the passage of air, and means on said shade individual to each aperture covering the aperture without preventing passage of the air therethrough.
2. A Window shade having a plurality of apertures for the passage of air, and means on said shade individual to each aperture including material similar to that of the shade covering the aperture Without preventing passage of the air therethrough.
3. A window shade having rows of Ventilating apertures for the passage of air, and a strip of ornamental design for each of said rows on the shade covering the apertures without preventing passage of the air therethrough.
4. A window shade having rows of Ventilating apertures for the passage of air, and a flexible strip for each of said rows secured to the shade covering the apertures without preventing passage of the air therethrough, said strip being secured to the shade by lines of stitching along one side and the opposite ends of each aperture.
