S. DORF WINDOW GUARD Filed April 6, 1957 INVENTOR ATTO R N EY Patented Dec. 12, 1939 UNETE TE This invention relates to window guards. An object of this invention is to provide an extremely simple window guard comprising a pair of interpivoted bars, the ends of which may be inserted in the grooves at the sides of the window frame, the construction being such that down ward pressure on the guard when installed, will serve to tighten the guard in the frame to prevent accidental loosening.

It is a further object of this invention to provide in a window guard of the character described, means to prevent the guard from being accidentally removed from or falling out of the frame, said means further serving to cut down the spaces between the guard, the window frame and the sash, providing an additional safeguard to prevent children or objects from falling through the guard.

Another object of this invention is to provide a strong, compact and rugged window guard of the character described which may be collapsed into a compact package, which is easy to install or remove, which shall be relatively inexpensive to manufacture, and, withal, practical and efficient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

I The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

In the accompanying drawing, in which is shown one of the various possible illustrative embodiments of this invention,

Fig. l is a front elevational view of a window frame, provided with window sashes and a guard embodying the invention;

Fig. 2 is a cross-sectional view taken on line 2-2 of Fig. 1;

Fig. 3 is a cross-sectional view taken on line 33 of Fig. 1;

Fig. 4 is a side-elevational view of the guard in collapsed condition, with the rope removed;

and

Fig. 5 is a front elevational view of part. of aframe, and window guard embodying a modified construction. I

Referring now in detail to the drawing, i ll designates a window frame in which are slidably mounted a front window sash. ii, a rear window sash i2, and which is provided with a window guard M embodying the invention. The frame may be of usual construction and the side portions thereof are provided with front and rear parallel spaced grooves l5 and it, in which the window sashes H and i2 are slidably mounted. Between the grooves l5 and it are furring strips ll. At the outer sides of the grooves 56 are furring strips 11a.

The window guard i l comprises a pair of elongated bars 58 and IQ of substantially the same length. These bars may be made of wood or any other suitable material and are preferably of substantially square or rectangular cross section. The bars are interpivoted at substantially the mid portions thereof by means of a bolt 22% passing through openings in said bars. When the guard is collapsed, the bars lie alongside one another having inner adjacent surfaces liia, 99a. The bar l8 may be provided with a countersunk 2! for receiving the head of the bolt. The bars 18 and i9 are preferably of similar cross section. The width of each bar is preferably more than half the width of the groove iii whereby the combined width of the bars is greater thanthe width of the groove. The outer ends of. the bar it are preferably formed with notches 22 and it at the outer side or surface i8b thereof, leaving narrowed end portions Zia and 23a at the outer ends of said bar. The depth of the notches 22 is equal to the difference between the width of the groove l6 and the combined widths of the bars i8, it.

The manner of installing the window guard will now be described. When the window guard is collapsed-the bars 18 and it! are co-extensive and superimposed one on the other. The inner face lea at the bar 58 facing the inner surface 59a of the bar 59. The bars may then be swung open about the bolt 2i! and the lower ends of the bars inserted at the bottom of the grooves it in contact with the bottom portion loo, of the window frame. The lower end 25 of the bar it is placed in contact with the furring strip ila at the outer side of onegroove Hi. The narrowed portion 2341 at the lower end of the bar it is contacted with the furring strip ii at the inner side of the other groove l6, and likewise in contact with the bottom portion Eta of the window frame.

The upper end it of the bar it extends within said other groove l6 and in contact with the furring strip Ha. The upper narrowed end 22a of the bar i8 is received in the first groove it and in contact with the furring strip Hi. It will thus be noted that with such construction the bars need not be forced into the grooves, as movement of the bars in their own planes about the pivot bolt 20 will move the outer ends of the bars into the grooves it at top and'bottom. The

furring strips l1 engage within the notches at opposite ends of bar H3.

The narrowed end 22a of the bar l8 may be provided with a bevelled surface 22b to contact the inner surface of the groove l6. The outer end of the bar [9 may also be bevelled as at 29a. to contact the inner surface of the other groove Hi.

It will now be noted that when the window guard is mounted within the window frame, there will be no looseness sideways, as one bar contacts the furring strip I! and the other bar contacts the furring strips l'la. Furthermore, should a weight be imposed downwardly, on the guard, the guard will become tighter wedged Within the grooves of the window frame.

Means is provided for retaining the guard within the frame against accidental removal. To this end the bar I8 is provided with a pair of

hooks

30 and 3! screwed into opposite side surfaces I80 and Mid thereof and spaced on opposite sides of the bolt 20. There is also attached to the bar [9 a pair of

hooks

32 and 33 screwed to the opposite side surfaces 19c and I9d thereof. A rope or tie cord of any suitable construction, designated by numeral 35 in the drawing, may be tied to the bar l9 above the hook 33, then looped about the bar l8 above the hook 3i, then brought down and looped about the bar [9 below the hook 32 and then looped about the bar i8 below the hook 3E! and then brought up and looped about the bar I9 above the hook 33 and tied thereto. The rope 35 will thus have two parallel

horizontal portions

35a and 35b and two vertical portions 350 and 35d. These portions traverse the triangular spaces between the bars and the sides of the frame and the window sash l2 above the guard, thus serving as an additional safeguard to prevent objects or persons, for example, children, from falling through the window guard. Furthermore, the rope prevents any pivotal movement of the bars about the bolt 20 and hence prevents accidental displacement or removal of the guard from the frame. Obviously the rope may be tied to the bars in any suitable manner, either being threaded through the hooks, or wound about the hooks.

It will be observed that with the construction described hereinabove, the front window sash H may be moved up and down to any desired position. If desired, furthermore, the window guard may be placed within the grooves I to permit up and down movement of the window sash l2.

In Fig. 5 there is shown a window guard Ma similar to the window guard i4, except that the bars 59 and 5? are of unequal length. With such construction the upper end 5|a of one bar may be located below the upper end 56a of the other bar. Thus, should a person desire to work at the window, for example, in hanging clothes on the line, at the left side of the window, the fact that one bar of the guard is lower than the other facilitates hanging of the clothes at the left side of the window. Furthermore, the bars 50 and iii are shown to have through openings 52, through which the rope 35 passes. The rope may be threaded through the openings 52 and tied to hold the window bars against pivotal movement and to prevent removal thereof through the window. Obviously, if it is desired to remove the guards l4 and Ma from the window, it is merely necessary to untie the cord.

Hooks may be aifixed to the ends of the bars, for engagement with the frame, so that the guard may be mounted on the outside or inside of the frame, instead of within the grooves.

The upper half of either one or the other of the bars may be omitted to give room for hanging out clothes, in which event a single flexible member may interconnect the bars to prevent them from opening up.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
