Smits, Duvernay, Ville de Laval, Quebec, Canada, assignor to Superseal Corporation, Douville St. Hyacinthe, Quebec, Canada, a corporation of Quebec Filed Aug. 26, 1968, Ser. No. 755,112 Int. Cl. Ed 13/02 US. Cl. 49-425 5 Claims ABSTRACT OF THE DISCLOSURE A corner gusset for window frames made of extruded plastic members, the inner surface of which has a series of serrations and the outer surface of which has longitudinally extending flanges which serve to reinforce the gusset and the window frame. A pair of roller assemblies are directly mounted on one of the arms of gusset.
The present invention relates to a corner gusset more particularly to a multifunctional corner gusset for window frames especially window frames formed of plastic material.
Generally corner gussets are used torigidify the corners of frames such as window or door frames and in conventional type construction wherein aluminum framing is used these corner gussets are generally bolted into position and function solely to strengthen the corner. In US. Pat. 3,105,274 another form of corner gusset is illustrated. In the patent the corner gusset is received within the hollow spacer frame that generally is filled with dessicant and functions to space the two window panes. Neither of the above-described constructions are suited for use with plastic frames, nor are they multifunctional.
It is thus an object of the present invention to provide a new corner gusset specially adapted for use in frames formed of extruded plastic members.
It is another object of the present invention to provide a new corner gusset adapted to perform a plurality of functions.
Broadly the present invention comprises a corner gusset having a pair of interconnected arms having inward and outward facing surfaces and etxending at right angles from one end of the other arm and terminating in sharpened free ends, a plurality of spaced transverse teeth formed on said inner surfaces each said tooth having a main surface sloping inwardly and away from said free end, and a rear surface sloping at an acute angle to said inner surface inwardly and away from said free end, said rear surface sloping at a greater angle to said inner surface than said main surface and a flange projecting from said outer surfaces and extending longitudinally of said rear surfaces.
Further details of construction of one form of the invention will be evident from the following detailed description and the accompanying drawings in which:
FIG. 1 is an exploded isometric view of the corner gusset of the present invention illustrating various attachments.
FIG. 2 is an enlarged detail of a short breadth of the gusset of FIG. 1 illustrating one end of the tooth shape of the gusset.
FIG. 3 is an isometric view of a window incorporating the gusset, and
FIG. 4 is a partial section along the lines 44 of FIG. 3.
As shown in FIG. 1 the corner gusset of the invention comprises a pair of perpendicularly extending arms 12 and 14 having inner surfaces 16 and 18 and outer surfaces 20 and 22 respectively. These arms terminate in free ends 24 and 26 which are sharpened as illustrated by taper sections 28 and 30 respectively which form wedge-shaped ends on the arms.
The inner surfaces 16 and 18 are each provided with a plurality of spaced teeth 32. The cross sectional shape of these teeth is illustrated in detail in FIG. 2. As shown each tooth 32 has a main surface 34 sloping inward and away from the free end of respective arms 12 or 14 at an angle 5 to the inner surface 16 or 18. Similarly each tooth has a rear surface 36 sloping inward and away from the free end 24 or 26 at an angle 0!. to the inner surface 16 or 18.
The angle ,8 will generally be in the range of about 1020 and preferably will be 15, while the angle a is less than 90 and generally in the range of 70-80", preferably Thus the rear surface 36 of each tooth 32 is undercut. The pitch of the teeth is preferably about inch with each tooth extending for about half of the pitch.
On the rear surfaces 20 and 22 are reinforcing flange means 38 and 40 respectively. As is evident from FIG. 1 the upstanding flange means 38 comprises a pair of longitudinally extending spaced flanges 42 and 44 interconnected by a pair of transverse members 46 and 48 provided with topped holes 50 and 52 respectively. These holes 50 and 52 are adapted to receive screws 54 and 56 which secure the handle member 58 in position to the gusset and thus to the window frame.
Flange means 40 similar to means 38 is composed of a pair of spaced longitudinally extending flanges 60 and 6-2 (see FIGS. 1, 3 and 4). Four transverse members 64, '66, 68 and 70 together with flanges 60 and 62 define a pair of spaced wheel wells 72 and 74. Wheels 76 and 78 are mounted in these wells 72 and 74 on suitable shafts 80 and 82 respectively and the ends of these shafts are mounted in suitable apertures 84, 86, 88 and 90 in the flanges 60 and 62.
In applying the corner gusset 10 to the frame, one arm, say arm 14, is forced into the slot 92 in the frame member 94 of the window 96 illustrated in FIGS. 3 and 4 and the other arm, arm 12 is forced into a similar slot (not illustrated) in the other frame member 98. It will be noted that the arm 14 is snugly received within the slot 92 and the teeth 32 are forced to bite into and engage the botom 100 of the slot 92 due to contact of the outside surface 22 with the inner surface of the overhanging flanges 102 and 104 on the frame (see FIG. 4). The slope of surfaces 34 and 36 of teeth 32 permits the arms 12 and 14 to be slid into the groove 92 or its equivalent but prevent these arms 13 and 14 from being easily withdrawn.
Thus one form of the invention has been described; others will be evident to those skilled in the art without departing from the spirt of the invention as defined in the appended claims.
I claim:
