1 Claim. (Cl. 211-90) This invention relates to a shelf adapted to be mounted on a window sill to hold a potted plant or other articles. It is an object of the invention to provide a shelf for this purpose which is simple in structure, low in cost, and easy to mount upon or detach from a window sill.

For a more complete understanding of the invention, reference may be had to the following description thereof and to the drawing, of which Figure 1 is a side elevational view of a shelf embodying the invention mounted on a Window sill which is shown in section;

Figure 2 is a plan view of the shelf illustrated in Figure 1;

Figure 3 is a fragmentary view similar to Figure 1, but of a modified form of the invention; and

Figure 4 is a perspective view of the shelf shown in Figure 3, but on a smaller scale.

The shelf illustrated in Figure 2 preferably consists of a single piece of sheet metal cut and bent to desired shape. The shelf comprises a body consisting of a plane sheet having a straight edge 12 as a part of its contour. Along the remainder of its contour is an upstanding flange 14 which is integral with the sheet 10 and serves to stiffen the shelf materially. If, for example, the shelf has a length of nine inches or so and a width of seven inches, the flange is at least one-quarter inch in height. The forward end 16 of the shelf illustrated on the drawing is arcuate but can be made with any other desired contour.

When the shelf is in position for use, the rear portion thereof rests on a window sill 18 while the forward portion projects out in front of the sill. The straight edge 12 at the rear of the shelf is flush with the outer edge of the sill and is provided with two or more ears 20 which project downward therefrom and bear against the outer edge of the sill 18. At the lower end of each car 20 are spurs or teeth 22 which are bent back toward the body of the shelf so that they penetrate into the outer edge of the sill to keep the shelf from falling off the sill.

It is evident that a small outward movement of the shelf will disengage the teeth 22 from the sill. To prevent this, fingers 24 are struck from the body of the shelf and are bent downward to engage the under edge of the sill. Cuts can be made in the shelf to form additional fingers 26 which can be bent down if required to bear against the inner edge of a wider window sill.

Instead of fingers 24 or 26 to bear against the inner edge of the sill, additional ears or fingers 30 may be formed on the straight edge 12 of the shelf to extend down therefrom against the outer edge of the sill. The ears or fingers 30 are longer than the cars 20, each ear 30 being provided with an extension 32 adapted to engage on the bottom member 34 of the window frame. Spurs or teeth 36 on the end of each extension 32 are bent down to penetrate into the bottom member 34 of the frame to hold the shelf against outward movement when the sash 38 is raised.

To install a shelf of the kind described, the window sash 38 is raised, the shelf is placed on the sill with the spurs 22 touching the outer edge of the sill. The ears 20 are then struck with a suitable tool such as a hammer to drive the spurs into the sill so that the cars 20 bear against the edge of the sill and the rear edge 12 of the shelf is flush with the outer edge of the sill. Fingers 24 or 26 are then bent down from the body of the shelf to bear against the inner edge of the sill.

If a shelf like that shown in Figures 3 and 4 is to be installed, the spurs 22 are driven into the outer edge of the sill as described, then the extensions 32 of the fingers 30 are struck to drive the spurs 36 into the bottom member 34 of the window frame.

I claim:

A shelf for a window sill comprising a plane metal sheet having a straight edge as a part of its contour, an upstanding flange extending along the remainder of said contour, a plurality of spaced ears projecting down from said straight edge, said ears having serrated extremities bent back toward said sheet to penetrate into the outer edge of a window sill, and a finger projecting down from said straight edge, said finger having an extension bent away from said sheet with a serrated extremity adapted to penetrate into the bottom member of a window frame when the shelf is mounted on the sill thereof.
