CORNER STRUCTURE Filed Aug. 1, 1945 Z06 l a/fen M kran/j.
INVENTOR.
A row/var.
J g This invention relates v metallic shapes to enable the formation of frames therefrom. g
' '(The principal object of the invention is the provision of a corner structure for uniting cut Patented Aug. 1?, 1948 by direct and mesne assignments,'to A'ce Storm I -Window' Company, YoungstowmOhio, a corporation of Ohio vApplication August to a corner structure for sections of a metallic shape to form frames for window openings. 7
A further object of the invention is the provision of a corner structure capable of aligning pieces being attached to one another during the formation of a frame therefrom.
A still further object of the invention is the provision of a corner structure utilizing a pair of simple locking corner pieces for aflixing cut sections of a channeled material to one another so as to form a frame.
The corner structure shown and described herein has been devised to enable the rapid and inexpensive formation of window frames such as may be advantageously employed in the construction of metallic storm sash. It is known in the art that in forming storm sash many sizes of window openings are encountered, each of which requires a custom built storm sash in order that the same may fit properly and achieve a satisfactory degree of insulation when installed. The invention disclosed herein enables strip lengths of suitably shaped framing material to be cut as with a miter box and the cut sections joined to one another simply and efiiciently and at the same time forming a strong and durable frame.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.
The invention is illustrated in the accompanying drawing, wherein:
Figure 1 is a top plan view with parts broken away and parts in cross section of the 'corner structure.
Figure 2 is a cross sectional elevation taken on line 2-2 of Figure 1.
Figure 3 is a perspective elevation of one of the members employed in the corner structure illustrated in Figure 1.
Figure 4 is a perspective elevation of another of the component parts of the corner structure shown in Figure 1.
By referring to the drawings and Figures 1 and 2 in particular it will be seen that a metal 1, 1945, Serial No. 608,198
3 Claims. (cuss-e6) shape Iii, preferably formed in continuous ex- 'truded lengths, is shown and is formed of a pair of oppositely"disposed'flanges ll and'an upstanding-centrally disposed rib 12, the metalshape 10 and the oppositely disposed flanges ll forming a continuous unbroken surfaceflange I3. The upstanding centrally disposed rib I2 is locatedon the opposite sideof the metalshape ld with respect to the surface flange l3. The centrally disposed rib i2 is provided at its uppermost ends with outwardly extending flanges I4 at either side thereof, which flanges M are formed continuously with the rib I2 and the under portions of which are undercut as indicated by the numerals IS. The area of the metal shape I0 adjacent the base of the upstanding rib I! is provided with a section of increased thickness, as generally indicated by the numerals l6, so as to provide for the formation of parallel continuous grooves l1 tapered at an angle opposite to that of the undercut tapered sections l5 heretofore described. It will thus be seen that when continuous strip-like lengths of the metal shape H) are cut on fortyfive degree angles, as illustrated in Figure 1 and indicated by the numeral l8, appropriately formed end sections may be joined as shown in Figure 1 and held in position as in the formation of a metallic storm sash frame by the simple expedient of employing a pair of channeled corner pieces I9 and 20, respectively.
By referring to Figures 3 and 4 of the drawings, perspective detailed illustrations of the flanged corner pieces l9 and 20 may be seen and it will be observed that they are similar in construction, each including a flange 19A and 20A, respectively, which, in combination with angularly formed side sections 19B and 20B, form channels I and 206 respectively. The channels I90 and 200 are adapted to receive the outwardly extending flanges M of the upstanding rib I! of the metal v shape In and the angular shape IBB and 203, respectively, and particularly the lowermost edges are adapted to register with the parallel continuously formed groove l'l heretofore described. It will thus be seen that when pairs of cut sections of the metal shape 10 are engaged with pairs of the corner pieces l9 and 20, as shown in Figures 1 and 2, a satisfactory and economic corner structure is achieved. The joined sections of metallic shape 10 are prevented from warping with respect to one another or moving out of proper alignment by reason of the plurality of closely engaging surfaces, particularly the engagement of the flanges ISA and 20A, respectively, over the uppermost edges of the outwardly extending flanges l4 of the upstanding rib l2 of the metal shape ID. This action, in combination with the aligning and holding of the component pieces made possible by the dovetailed formation of the corner pieces engaging the dovetailed sides of the upstanding rib l2 of the metal shape 10, results in an unusually strongand durable cornerstructure.
It willv be seen that a simple and eflicie'nt metal frame of desired size and configuration may be formed bythe utilization of the structure disclosed herein, that is, the dovetailed channels along the axially extending upstanding central rib thereof and the pairs of channeled corner pieces shaped to be insertable in the dovetailed channels along the axially extending rib of the metalshape, I0,
Having thus described my invention, what I claim is:
1. A corner structure comprising in combination a shape having an axially extending rib, the said rib having undercut channels formed on either side thereof, and an L-shaped corner piece havin an axially extending dovetailed projection along one side thereof and an outwardly extendi;ngflange overlying the said dovetailed projection, the dovetailed projection registering with one. of; the said undercut, channels, and the outvvardly extending flange overlying the said rib.
2-. A corner structure comprising in combinaatiOn. a shape having an axially extending upstanding rib, the said upstanding rib having a channel formed in at least one side thereof, the edges of the said channel undercut with respect to the said shape so as to form a dovetailed channel; and an L-shaped corner piece provided with a dovetail shaped extension along one side thereof and having. an outwardly extending flange overlying the said dovetail shaped projection, the dovetailed projection registering with the said dovetailed channel and the outwardly extending flange partially overlying the said upstanding rib.
3. A corner structure comprising in combination a shape having a surface flange and an axial- 1y. extending upstanding rib on the back thereof, continuous axially extending dovetailed channels formed in each side of the said upstanding rib and an L-shaped corner piece having a dovetail shaped projection continuously formed thereon, and an upwardly and outwardly extending flange continuously formed thereon overlying the said 7 dovetail shaped projection, the dovetail shaped projection registering with one of the continuous axially extending dovetailed channels in the said upstanding rib, and the upwardly and outwardly extending flange continuously overlying the said upstanding rib;
