WINDOW GUARD FASTENER Filed Feb. 5, 1945 DAVID MIIIDNALU INVENTOR.
Patented July 22, 1947 UNITED STATES 2 Claims.
This invention relates to a metal window guard, more particularly a window guard such as is disclosed and claimed in my prior Patent No, 1,893,176, dated January '3, 1933. The principal object of my invention is to provide an improved window guard of the general type therein disclosed which shall be effective to prevent the entry of thieves and pilferers without destroying the guard and thus attracting attention.
A further object of my invention is to provide a window guard embodying fasteners which enter into the sides of the window frame and which cannot be removed without destroying the connection with the fasteners on both sides of the guard.
Briefly, my improved window guard is similar to that shown in my prior patent in that it comprises horizontal bars with vertical rods joined thereto and with fastening means entering the sides of the window frame, said fastening means having curved ends directed inwardly of the frame. Window guards made in accordance with my prior patent have proved eminently successful in use, but on some occasions thieves, or pilferers have cut off the fasteners from one side of the window guard and, due to the fact that each fastener is secured to the bar by means of a single stove bolt, the free end of the guard could be hinged about the bolts securing the fasteners on the opposite side of the window. In accordance with my present invention, I have provided flanges on the fasteners against which the horizontal bars hear when assembled, and which are effective to prevent angular motion of the window guard assembly with respect to the fasteners.
A window guard embodying features of my invention is illustrated in the accompanying drawing, forming a part of this application, in which Fig. 1 is an elevation, partly in section, viewing my improved window guard from the outside of the window;
Fig. 2 is a sectional view taken along the lines IIII of Fig. 1;
Fig. 3 is an edge view of one of the fasteners drawn to a larger scale; and
Fig. 4 is a plan view of one of the fasteners.
Referring to the drawing for a better understanding of my invention, I show my improved window guard as applied to a window comprising a frame l0, an upper sash II, and a lower sash IS. The upper sash I is counter-balanced by the usual sash weights l2 and the lower sash by means of the usual sash weights I3, shown in Fig. 2. It will be understood however that the window guard is adapted for practically all kinds of windows and openings in a build- Positioned directly beneath the upper sash H is my improved window guard assembly which comprises .an upper horizontal bar 14, a lower horizontal bar l6 and. a plurality of vertical bars I! which pass through holes in the horizontal bars and are secured thereto in a manner well understood. The sides of the window frame II) are provided with holes 18 opposite the ends of the horizontal bars l4 and I6. Secured to the ends of the horizontal bars I4 and 16 are my improved fasteners, each of which comprises a body 19 having an elongated slot 2| therein and a curved hook-like end 22 which enters the hole It with the curved end directed inwardly of the window. It will be seen that with the window guard assembled as shown in Figs. 1 and 2, any outward pull on the window guard serves to engage the hook end 22 of the fastener more tightly in the hole l8. The fasteners are preferably joined to the horizontal bars by means of stove bolts 23, having their heads fitting in countersunk holes 24 in the :bars, and with their other ends preferably split and riveted over the nuts 25 as shown at 26. Thus, any attempt to unscrew the nuts on the ends of the bolts only serves to turn the bolts and does not unscrew the nuts.
In order to prevent relative angular movement between the horizontal bars I l and. I6 and their associated fasteners, I provide an upturned flange 28 and a downturned flange 29 on each of the fasteners, one of which will engage the side of the associated bar when the window guard is installed. By providing both an upturned and a downturned flange, any fastener can be employed on either end of the associated horizontal bar. With the fasteners thus designed and with the window guard assembled as shown in Figs. 1 and 2, it will be seen that it would be necessary to cut all the fasteners loose on a window guard in order to obtain entry. The necessity of using so much destructive force is a great deterrent to its being exercised.
From the foregoing it will be apparent that I have devised an improved window guard which is simple of design and construction and one which, when assembled, is effective to deter unauthorized entry without the exercise of destructive force.
While I have shown my invention in but one form, it will be obvious to those skilled in the art 3 that it is not so limited, but is susceptible of various changes and modifications, without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are specifically set forth in the appended claims.
What I claim is:
1. A fastener for securing a flat ended horizontal bar of a window guard to a window frame comprising a hook on one end to engage the window frame and a body adapted to be secured to the horizontal bar, a flange turned up from the body along one side and a second flange turned down along the same side of the body, said flanges bein disposed to engage the edge of the bar and hold it against angular movement with respect to the fastener on whichever side of the body the bar is secured.
2. A fastener as set forth in claim 1 in which one of the flanges is disposed along one half of the body and the other along the other half.
