This invention relates to safety devices for windows and more particularly to an improved window guard construction.

It is well known that it is not feasible to protect all windowswith heavy iron bars or the like but it is also true that many accidents are caused as the result of windows being left open with nothing to guard the opening. It

is an object of this invention to provide a simple and inexpensive window guard suitable for insuring adaquate safety without the necessity of employing unsightly bars which in addition to being undesirable in appearance may constitute a serious fire hazard and prevent necessary access to the windows. More particularly, it is an object of this invention to provide a window guard which is entirely invisible except whenthe window is 7 open. In other words our improved window guard 1s in evidence only when it is serving its useful function of protecting the opening.

formed by raising the window.

Our improved window guard is automati- 11 cally extensible and therefore adapted to accommodate any sized opening determined by the height to which the window is raised. In general our improved window guard comprises a plurality of lengths of cable, or other flexible material, connected to the window casing and to the window sash, these connections being made in such a way as to permit the window to be raised in the usual manner and the act of raising the window causes the cable members to be stretched across the opening covering the entire area of the opening regardless of the height to which the window is raised.

For purposes of economy the improved window guard can be made out of a single piece of cable,.or similar material, fastened to the window frame and cooperating with a plurality of guide rollers, or the like, carried by the window sash. lVhat may be regarded as a tension member is anchored to some fixed support, such as the window frame, and

serves to keep the cable members taut at all times, regardless of the position of the window sash with respect to the frame. we prefer to provide a suitable casing for the guide rollers, which serves the purpose of concealing these rollers and also entirely concealing the cable when the window is closed. This casing may be detachably secured to the window sash and the above mentioned tension member may be releasable so as to permit the window guard to be temporarily removed from the window sash whenever it is necessary to gain access to the outside of the building, or to the exterior of the window, as for the purpose of washing the same.

The various objects and advantages of our invention will be more apparent upon considering the following detailed description which is to be taken in conjunction with the accompanying drawings in which Fig. 1 is an elevation of a window provided with one embodiment of our invention;

Fig. 6 is a diagrammatic view illustrating the mode of operation of the embodiment of our invention illustrated in Fig. 1

Figs. 7 8 and 9 are perspective views of portions of the device illustrated in Fig. 1.

Referring to the accompanying drawing and particularly to Fig. 1, we have illustrated a window frame at 1 having a window sill 2 and accommodating a lower window sash 3 and an upper sash 1. The window frame and in fact the entire construction of the window may be standard throughout for it is not necessary to modify the construction of the window in any way in order to utilize the present invention, although of course certain parts of the invention may be built into the window structure if desired.

At 5 in Figures 1, 2 and 7 we have illustrated a metal strip in the form of a channel which may be secured to the window sill in any suitable manner. This metal strip is provided with a plurality of holes 6 at intervals along the strip and adapted to receive a flexible guard member 7 which may consist of Wire, cable, or the like. One end of the cable member 7 may be fastened near one end of the Window sill, as shown at 8, and the other end may be fastened near the other end of the window sill, as illustrated at 9.

The Window sash 3 carries a plurality of guide members cooperating with the cable member 7. These guide members 10 are preferably, though not necessarily, in the form of rollers, such as that illustrated in detail in Fig. 2 and they may be either attached to the sash directly, or carried in a suitable housing, such as that illustrated at 11. This housing is preferably in the form of a channel member extending along the window sash and secured thereto by any suitable means. The housing 11 may be detachably secured to the window sash, as by providing a plurality of bayonet slots, such as that shown at 12 in Figures 3 and 8, cooperating with corresponding projections 13 secured to the window sash.

Located at a point substantially level with the lower edge of the window sash when the window sash is raised to its highest position, is a tension member 14, a suitable form of which is best illustrated in Fig. 5. This embodiment of the tension member coinprises a roller 15 carried on a lever arm 16 hinged to a suitable support 17 attached to the window casing and normally locked in its uppermost position by any suitablelocking means, such as the ring 18, which is adapted to slip over the end of the lever member 16.

The cable member 7, above described, is adapted to pass over the guide members 10 and along sections of the metal strip 5 to form a plurality of cable lengths covering the opening formed by raising the window sash. 'By referring to Fig. 1 it will be noted that from the fastened end 8 of the cable member, this member extends over the guide roller 10*, then along the channel formed by the housing 11 under a guide roller 10 located at the end of this housing, then up along the window frame to the tension member 14. This much of the device is illustrated diagrammatically in Fig. 6 in which the horizontal center line represents the window sash carrying the guide member 10 10 and 10. By referring to this Fig. 6 it will be understood that as the window sash is raised, the vertical length of the cable member below the sash becomes longer and the vertical length of the cable member above the window sash becomes shorter, these changes being exactly equal and therefore completely compensating each other. hen the window sash occupies its lowest position the major portion of the cable member extends along the side of the window frame substantially in alignment with the tension member 14, whereas, with the window sash in its uppermost position the major portion of the cable member extends between the sash and the window sill across the opening formed by raising the window.

Referring again to Fig. 1 and bearing in mind the previous description of the cable member extending up to the cable member 14, it will be noted that the cable member then extends down under guide member 11, over guide member 10, along the channel formed by housing 11 to the guide member shown at 10". From the guide member 10 the cable extends down through one of the'openings in the metal strip 5 and along the channel formed in this strip to the adjacent opening in the same, and then up and around the guide member 10, back through the channel in housing 11, under guide member 10 and back up to the tension member 14:- In similar manner the cable member may be threaded around the other guide members and through the other openings in the metal strip 5 to form a plurality of cable lengths extending between the window sash and the window sill, as illustrated in Fig. 1 and it will be understood that the operation of the device with respect to all of the cable lengths is just the same as that previously described in connection with Fig. 6. The several cable lengths can be formed out of separate pieces of flexible cable, or the like, or they may conveniently consist of a single piece of cable fastened at the two ends, as illustrated at 8 and 9, the cable lengths being formed out of loops in the single piece of cable.

From the above description it will be understood that when the window sash is in its lowered position the major portion of the cable member extends up along the side of the window frame to the tension member, whereas, when the window is raised the cable members are stretched across the opening formed by raising the sash. When the window is closed the cable members are concealed by the housing 11 and the cable lengths extending up alon the side of the window frame may be concealed by any suitable means, such as the cover plate 19 attached in any suitable manner to the window frame.

W'henever it is necessary to remove the window guard the tension member 1 1 may be released by merely raising the locking ring 18 and allowing the lever arm 16 to drop into its lowered position, as indicated in dotted lines in Fig. 5. This releases the tension in the cable member and permits ready removal of the housing 11 from the window sash.

It is to be understood that our invention is 'not limited to the details of construction of the particular embodiment illustrated in the accompanying drawing but includes all embodiments of the invention coming within the scope of the appended claims. For example, while we have illustrated the inven tion as applied to the lower window sash, yet it is equally applicable to the upper sash in which event the cable member would be secured to the upper portion of the window frame, instead of to the window sill, as illustrated in the accompanying drawings.
