2 Sheets-Sheet 2 FIGS INVENTOR PHILIP M. ALEF ATTORNEYS MASKING DEVICES BACKGROUND The art has long been aware of masks of various forms for use in painting peripheries of rectangular surfaces, such as frames of windows, mirrors, floor areas, but more specifically windows. A variety of masking means have been known, including rectangular sheets.

OBJECTS The present invention provides masking devices in the form of triangles which can be applied to the surface and overlapped to cover the entire surface with portions of the masks, as needed, being cut away so that while all of the surface is covered, there is no coverage over the periphery to be painted.

The triangles may be right triangles, equilateral triangles or isosceles triangles.

The triangles may be equipped with suitably provided adhesive means along certain or all of thier edges as desired, and possibly, and aprticularly where the masks are large in area, with suitably applied adhesive means inside their edges.

THE DRAWING The appended drawings show preferred forms of the invention. In the drawings:

FIG. 1 shows a framed glass surface with two'right angle masks.

FIG. 2 is a reverse side view of one'of the masks of FIG. 1.

FIG. 3 is a similar view but showing a slightly different form of adhesive application.

FIG. 4 is a fragmentary view showing still another form of adhesive with tear of protective strip.

FIGS. 5-10 show still other variations.

DETAILED DESCRIPTION FIG. 1 shows a surface having a peripheral frame 12 to be painted. One right triangle mask 14, is shown in place for masking the glass area 10 while exposing the frame 12.

FIG. 2 shows maks 14 equipped with fixed adhesive 16,17 and 18 with adhesive 18 set back from the hypotenuse edge 19 for ease of removal.

FIG. 3 shows the mask 14 with peel back type of adhesive tape strips 20, 22 and 24.

FIG. 4 shows a step in the peeling off of a protective covering 26 from adhesive strip 27 on a mask 14.

tri-

FIG. 5 shows an isosceles triangular mask 30 with adhesive at its edges 32 but also at its center 34 and in spots 36 along the hypotenuse.

FIGS. 6, 7 and 8 show variations employing fixed adhesive F and peel off adhesive tape T at selected edges as shown. In another variation shown in FIG. 9, we start with a rectangle, perforated on diagonal 40, to form two triangular masks 14.

FIG. 10 shows a roll R perforated at 42 and 44 into rectangular and triangular sections, 14.

THE ADHESIVE The adhesive could be a commercially available pressure sensitive tape which usually comes equipped with protective tear off strips as part of the construction. Other forms of adhesive could be used where desired.

The adhesive may be sprayed or printed where desired onto the mask.

The adhesive application and its dimensions may be any one of the following: air spraying; electrostatic spraying; block or pressure printing; roll printing; applied double sided tape application; three-quarters of an inch or less in width; all as desired.

It will be manifest that triangular masks such as here shown, by virtue of the geometry, can be shuffled around on a rectangular surface for masking it. Fortions of the masks that overly the frames may be cut off so as not to interfere with the painting of the frames.

The geometry of the triangles and particularly where right triangles are used, provides the essence of the invention, the adhesive being used for its obvious purposes, to secure the masks in position once they are placed in their desired location.

Now having described the mask hereof, reference should be had to the claim which follows.

I claim:

1. Masking means for use in painting peripheries of rectangular surfaces, comprising a rectangle of sheet material perforated along a diagonal, which can be used as a whole or separated and arranged in triangles with their hypotenuse overlapping and adjustably movable for fully masking the surface;

and strips of adhesive upon the back of each triangle along the side edges and hypotenuse thereof;

said masking means being formed in a continuous roll having a series of longitudinally spaced transverse performations, manually separable to form said rectangular sheets.
