Whitener, Long Beach, Calif., assignor to Universal Molding Company, Lynwood, Calif., 21 corporation of California Filed Mar. 9, 1965, Ser. No. 438,237 1 Claim. (Cl. 52-738) This invention relates to a screen frame and more particularly to one which is formed of sheet metal in a rolling operation.
In rolling frame sections for window and door screens and the like from sheet metal, and preferably aluminum, it is customary to form a spline groove adapted to receive an edge of the screen fabric and a deformable spline of a suitable material such as a weatherproof plastic. The frame generally has a main body portion of tubular shape, preferably rectangular in cross section, and an integral spline groove formed by rolling one longitudinal edge of the metal stock over the opposite longitudinal edge and clamping the rolled joint of said edges of stock by what is termed as stitching. This comprises the provision of spaced indentations longitudinally of the exterior surface of the spline groove to lock the rolled over edge portion of the metal stock to the opposite edge portion over which it is rolled. While the stitching or spaced indentations are not extremely large, they can readily be seen.
It is an object of the present invention to provide a rolled screen frame section from which screens can be assembled in which the objectionable appearance of the line of stitching or spaced indentations has substituted therefor a continuous groove to lock the rolled over edge of the stock and the opposite edge over which it is rolled, not only to provide a continuous locking structure but to greatly enhance the ornamental appearance of the screen frame.
A further object of the invention is to provide means whereby the continuous groove which locks the rolled over edge of the stock is used in combination with knurling to prevent the locked edges of the stock from relative movement longitudinally of the frame section.
The above and other objects of the invention will more fully appear from the following description in connection with the accompanying drawing, in which:
FIG. 1 is a perspective detail of a corner of a screen frame embodying the invention;
FIG. 2 is a section taken approximately on the line 2-2 of FIG. 1 on an enlarged scale;
FIG. 3 is a cross-sectional view of the screen frame, and a more or less diagrammatic indication of the rollers used to produce the locking structure of the invention.
The screen frame includes a body 4 preferably of generally rectangular shape. The body is formed from a longitudinal strip of metal whose edge portions project from the body and are rolled to provide a spline groove 6. One edge portion extends laterally as at 8, and thence outwardly as at 10, and its more extreme edge portion 12 is rolled over the other edge 14. The first mentioned rolled edge portion 12 terminates at 16 above the bottom 18 of the spline groove 6, and said edge 16 provides an abutment for more securely retaining the screen fabric 20, and a deformable plastic or other suitable screen fabric retaining spline 22.
In order to securely lock or clamp the rolled over portion 12 of the first mentioned edge to the other edge portion 14, I provide a substantially continuous groove 24 which is pressed into the first mentioned flange portion as by a groove forming roller 26 and a back-up roller 28. The stock is previously knurled as at 29 so that when the continuous groove 24 is formed by pressure of roller 26 toward roller 28, the knurled portion 29 will bite into 1 3,374,597 Patented Mar. 26, 1968 the adjacent metal surface to prevent relative longitudinal movement of the rolled over portion 12 and the other edge portion 14. The knurling 29 forms a continuous interlock because of the continuous groove 24, as distinguished from the interlocking of only approximately 50% where knurling is used in combination with conventional stitching, In prior practice the roller 26 would have spaced teeth forming spaced identations in place of the groove 24. As shown in FIGS. 2 and 3, this provides a secure lock of the flange portions 12 and 14 in a plane extending through the flange portions 10 and 12 of the first mentioned flange and that portion of the other flange 14 over which the first mentioned flange is rolled.
The outer edge face 30 of the screen frame section is concave transversely as shown in the drawing providing a convex inner face which is adapted to frictionally engage a flange 34 on a corner locking element 32 which is formed on a angle so that it will have its legs positioned in adjacent end and side portions of the frame sections 4. It will be seen in FIG. 2 that the flange 34 of the locking member 32 has its outer edge also firmly seated in the corner provided by the-inner side of the frame face 30 and the inner side of the adjacent frame face 36.
Not only does the continuous locking groove 24 provide more secure locking of the rolled flange edges of the first mentioned flange portions 10 and 12 relative to the other flange portion 14 than does intermittent indentations or stitching, but it greatly improves the appearance of the finished screen frame section, since it eliminates the objectionable appearance of the row of indentations produced by stitching.
It will of course be understood that various changes can be made in the form, detail, arrangement and proportions of the various parts, without departing from the spirit of the invention.
I claim:
1. In a metal screen frame section or the like, a rolled tubular body having a smooth external surface, said body having laterally and thence upwardly extending flanges whose edges terminate in laterally spaced relation to said body to define a spline groove, one flange edge comprising an outer edge portion rolled over the other edge, and terminating in said outer edge portion above the bottom of the spline groove to provide a spline retaining shoulder and a continuous locking groove rolled longitudinally into said first mentioned flange exteriorly of the spline groove and upwardly from the bottom of the spline groove relative to said shoulder and inwardly from said other edge to clamp the rolled over flange edge thereof to said other flange, said face of one flange edge in contact with a face of the other flange edge being knurled along the continuous locking portion provided by said continuous locking groove.
