-QMKL United States Patent 3,015,358 COLLAPSIBLE OUTSIDE WINDOW SHADING DEVICE Serena Kennedy, 158 E. 32nd St., Apt. 9, New York 16, N.Y.

Filed Jan. 20, 1958, Ser. No. 709,972 2 Claims. (Cl. 160-53) This invention relates to an improved window shading device, which will eifectively shade a person sitting at 10 a window and yet allow ample ventilation through an open window sash, and permit unobstructed vision through this open window space, so that a sick or tired person may enjoy the protection and seclusion of a private room and obtain the benefits of fresh air and a stimulating view of the outdoors.

One of the objects of the invention is the provision of an outside window shading device, with a radially collapsible covering, zhich can be supported on a socket attached to the sill of the window frame, and shifted to elevated open shading position, or to collapsed closed position, by a hand movement through the open window, and which will be reinforced when in open position against the thrusts of wind.

Another object of the invention is the provision of an outside window shading device, having a pole or staii, a series of ribs pivoted radially to a support on this staff, and describing considerably less than a full circle, so that shade protection will be limited to the area outward of the window and the shade protector may be mounted close to the window, the device being also equipped with means for securing the collapsible ribs and the shade covering material mounted thereon, either in open shading position, or in collapsed closed position, and an arched guiding bar on which the individual ribs have sliding movement, which is automatically raised to horizontal position when the ribs are opened, and which serves to stiffen the open ribs and shade covering material against displacement from thrusts of wind.

With the above and other objects in View the invention relates to certain new and useful constructions, combinations and arrangements of parts, clearly described in the following specification, and fully illustrated in the accompanying drawings, in which:

FIG. 1 is a view in elevation of a window provided with my improved shading device, which is shown in open shading position.

FIG. 2 is a similar view, showing the shading device collapsed to closed position.

FIG. 3 is a top plan view of the device, shown in open shading position.

FIG. 4 is a vertical sectional view through the device, enlarged, with the staff shown broken away.

FIG. 5 is a detail sectional View, taken on line 55 of FIG. 4, looking in the direction of the arrows.

Referring to the accompanying drawings, which illustrate the practical embodiment of my invention designates a conventional window frame, having the usual sill 11, the upright sides 12 and 13, and the top casing 14. Within this window frame the upper sash 15 and the lower sash 16 slide vertically in the usual manner, and in this showing the lower sash 16 is shown to be elevated to provide an open ventilation window space S, to allow fresh air to freely circulate through the room.

During periods of the year many persons who must remain indoors seek to have fresh air, without constant exposure to the sun. Roller blinds and venetian blinds do not allow both full circulation of fresh air to the room and at the same time provide ample shade protection against strong sun rays. Awnings must require permission of landlords, are expensive to install, and must be tailored to flt each window space, and when installed by a tenant ice are usually abandoned when the tenant surrenders possession of the premises.

To overcome these deficiencies I have invented a portable window shade protector, which can be mounted in place by the tenant, which can be removed without difficulty and installed in any other window, and which will give substantial protection against strong sun rays and yet allow free and unobstructed ventilation through an open window space, and at the same time afford satisfactory protection against rain and showers.

In carrying out my invention 1 mount a cast metal socket 20 on the window sill, by means of screws or the like, and in this socket I insert a staff 21, of strong wood or of metal, and clamp this staff in place by means of the screw 22 threaded through the wall of this socket against the stafi 21.

On the staff 21 I mount a metal ferrule 23, which is formed or provided with a pair of semi-cylindrical jaws 24 and 25, provided with radial slots 26, and which are spaced apart to provide a groove 27 in which the wire ring 28 is disposed. As shown in FIG. 5 radial slots are formed in the twin jaws or flanges 24 and 25, spaced equal distances from each other. The bore of the ferrule 23 is shown to be D-shaped, so as to have a non-rotative fit on the staff 21, which is also D-shaped in cross section. This ferrule may be secured to the upper end of the staff, as by the cross pin 29.

in each of the slots 26 the upper end of a rib 30 is supported for pivotal movement on the wire ring 28, which is also D-shaped, so that it will resist turning in the groove 27. On the staif 21 of a metal slide 31 is mounted, and the upper end of this slide is formed with a pair of semi-circular flanges 32 and 32a, which are spaced apart to provide a groove 33 between these flanges, and the flanges are formed with radial slots 34, equal in number and in spacing to the slots 26 of the ferrule and separator 23.

The sliding member 31 is formed with a D-shaped bore so that it will have a non-turning fit on the staff 21, and a wire ring 35, also D-shaped in form, is inserted in the groove 33. A brace rod or member 36 is disposed in each of these slots 34 and pivotally connected by the ring 35 to the sliding member, and the outer end of each brace member is pivotally connected at 37 with one of the radial ribs.

The slide is formed or equipped with a heavy collar 38, in which the end of the screw 39 is threaded, and the staff 21 is formed with a plurality of circumscribing grooves 21b to receive the pointed inner end of the screw, so that the sliding member 31 may be locked to the staff in elevated position or in lowered position, by merely tightening this screw, shown to have a winged head 39a.

Having described my invention I claim as new and patentable:
