This invention relates to a window frame construction. In practice, on installation of window frames comprising top and side members, the junctures or top corners thereof are frequently open slightly or out of registry forming a weak structure of non-workmanlike appearance. Pursuant to the invention, a window frame construction is provided including an elongated or top window frame bar and side window frame bars assembled with their ends in abutting juncture. |

DETAILED DESCRIPTION I claim: 1.
A window frame, comprising: (a) a top bar having opposite ends, (b) a pair of side bars abutting the top bar ends, forming, therewith, two top window frame corners of an inverted U-shaped window frame configuration, (c) a pair of plates, (d) each plate including a triangular side wall portion telescopically registrable with and covering the abutting ends of the top and side bars, (e) each plate further including a pair of flanged portions bent angularly from two adjacent edges of the side wall portion and each disposed at right angles thereto, (f) each plate further including a pair of spaced trapezoidal gripping portions, bent angularly beyond the flanged portion and parallel to the side wall portion and defining therewith a Y-shaped slot receiving said abutting corner of the top bar and side bar, (g) each plate further including a plurality of parallel spaced elongated indentations formed in each of said gripping portions, parallel with flanged portion of the plate from which such gripping portion depends, and spaced therefrom and frictionally engageable with and covering said abutting portions of the top and side bar, (h) said indentations reinforcing said top and side bars.
Description:
SUMMARY OF THE INVENTION The invention is designed to overcome disadvantages of prior structures by providing an easily-applied combination window frame construction including an elongated channelled horizontal or top window frame bar and channelled side window frame bars corner assembled with their ends in abutment, defining an inverted U-shape, and closure plates covering abutting corners of the window frame and frictionally engaging connecting and holding them in registry, said closure members being of such structural features as will enable them to be readily prefabricated and furnished to builders and contractors for simple installation, in situ, without use of any tools.
The closure unit, thus applied, becomes an essentially unitary interlocking part of the window frame, effectively closing the corners and enhancing the appearance of the frame and holding the window frame bars closed position against accidental displacement thereof
