BLACK-OUT DEVICE Filed Feb. 20. 1942 Patented July 4, 1944 UNITED STATES PATENT o Sam J. Bates, East Point, Ga.

Application February 20, 1942, Serial No. 431,751

1 Claim.

This invention relates to a blackout device for windows and similar structures, and has for the primary object the provision of a device of this character which may be conveniently adapted to a Window frame and brought into operative position for providing positive exclusion of light through the window and which may be easily moved into a position of completely uncovering the window, so that a full amount of light and ventilation may be had.

Another object of this invention is the provision of an opaque shade mounted so that said shade may be operated in a conventional manner and the mounting cooperate therewith in excluding light about the edges of said shade when in window-shading position, also acting to releasably secure the shade in the last-named position.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a transverse sectional view illustrating the application of the invention to the window frame.

Figure 2 is an enlarged fragmentary sectional view showing the means of releasably securing the shade in operative position and coacting therewith in excluding light between the lower edge of the shade and the window frame or sill thereof.

Figure 3 is a fragmentary perspective view illustrating the shade catch.

Figure 4 is a fragmentary perspective view illustrating a portion of one of the vertical side 4 portions of the shade frame.

Referring in detail to the drawing, the numeral 5 indicates a conventional type of Window wherein the frame thereof is indicated by the character 6 including the usual sill 8. The disclosure of the window 5 is made solely for the purpose of showing one of the uses of the present invention and the simple way in which the latter may be adapted to the window for the purpose of providing a positive exclusion of light through the window when desired.

It is to be understood that the present invention is readily applicable to doors, that include transparent mediums and other devices.

In order that the present invention may be readily adapted to the window or similar device, a shade frame 9 is provided and which may be readily secured onto the window frame by nails or similar fasteners and includes vertical channel type side members II and a sill strip I2 mounted on and secured to the sill 8. The side channel members II and sill strip l2 coact with each other and snugly engage the window frame to prevent the passing of light between the window frame and the shade frame.

A conventional type of shade roller (not shown) may be mounted on the frame 5 and carries an opaque shade M which may be wound on or off of the roller 13 as desired.

The width of the shade is sufficient for the vertical edges thereof to enter the side channel members H and adapted to slide freely therein.

The sill strip [2 includes a vertically arranged portion l6 bent to form a keeper or restraining member 11. Secured to the free end of the shade is a hook-shaped member l8 to be engaged and disengaged in the keeper H. The hook-shaped member l8 includes an attaching strip I9 which may be riveted or otherwise secured to the shade M, as shown at 20. The length of the attaching portion I9 is equal to the width of the shade and the hook-shaped member I8 is slightly shortor than the attaching portion, as shown in Figure 5. However, the hook-shaped member !8 enters the channel vertical members II and in order that it may be engaged and disengaged with the keeper H, the front walls of the channel shaped members II are oifset, as shown at 22, and are slightly shorter in length than the remaining portions of said members II in order that the hook-shaped member I8 may be engaged and disengaged with the keeper 11.

When the hook-shaped member I8 is engaged with the keeper it coacts therewith and with the portion l6 of the sill strip in excluding light between the sill and the lower edge of the shade.

When the shade is pulled downwardly and the hook-shaped member l8 brought into engage ment with the keeper I1, 3. positive exclusion of light through the window will be had. At any time desired the shade may be rolled upon the roller so that the full amount of light and ventilation may be had through the window.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is:

In a securing device for a shade, a vertical channel member secured to a frame for guiding and slidably securing a shade to the frame and having one wall notched and its wall opposite thereto offset outwardly and terminating short oi the lower end of said member, a sill plate extending into the notched wall of said member and having a portion bent to extend outwardly l0 and downwardly from the frame to provide a keeper, and a strip secured to the traveling end of the shade and having a hook shaped portion of a length less than the length of said strip to provide an extension slidably received by the channel member and movable from and toward the frame by moving into and out of the 01T- set wall of said member to facilitate engagement and disengagement of the hook shaped portion of the strip to and from the keeper.
