wmnow GUARD.

Application. filed March 30, 1928.

My invention relates to improvements in window guards.

My improved window guard is intended for use in connection with window frames wherein a window sash is movable either in the frame, or to and from the frame so as to leave an opening. I am aware of the fact that guards for such openings have heretofore been designed and that various means for concealing the guard when the window is closed have been disclosed.

The object, however, of my invention is to provide a window guard which is entirely removable from a window frame and sash and at the same time provide a case for the members forming the guard in such a location as to protect the device from ice and the elements.

Another object of my invention is to so dispose a set of telescopic rods and tubes within a housing for service as a window guard as to make possible their telescopic extension to guard the entire window opening.

In the drawings:

Figure 1 is a front view of a two light sliding window structure provided with my improved window guard.

Figure 2 is a similar view of the same window showing the sash closed in the frame and showing the case cut away to disclose the guard in collapsed position.

Figure 3 is a section on line 33 of F igure 1.

Figure 4 is a detail front view of the method of attaching the case to the sash.

Figure 5 is a section on line 55 of Figure 1.

Figure 6 is a section on line 66 of Figure 1.

Figure 7 is a detail of the member.

Figure 8 is a detail of the lateral guard member.

Figure 9 is a detail of a cross guard member.

Like parts are identified by the same refcentral guard erence characters throughout the several viewsrm I have here disclosed my device incorporated in a window structure wherein the window frame 10 provides a guideway 11 for a sliding sash element 12, stops 13 and 14 on either side of the window frame be Serial No. 265,915.

slides upwardly or downwardly. It will be obvious as I complete my description of my improved guard that it may be likewise at tached to casement windows or other openable windows wherever there is an opening between sash and frame to be guarded.

It is of course well known that when a window such as that disclosed in the drawings is tightly closed the lower rail 15 will rest partially below the upper edge of the window sill 16 so as to make a water-tight lap joint therebetween. I, therefore, provide a construction which will be adapted for installation adjacent the lower rail of the window sash and supported by the sill in the following manner.

My entire guard device is mounted upon a bed plate 17 and com rises as a major part of its frame-work a ousing on case 10 superimposed upon the bed plate, and adapted to house the guard members hereinafter described, and since, as described above, it is of-importanee that the general structure of my device be easily removable from the window, I have provided for a telescopic structure in my bed plate as indicated at 18. It will likewise be noted that the outer ends 19 of the bed plate are much thinner than the central portion and it is by this means that I enable the bed plate to be placed on any window sill and forced outwardly with light taps of a hammer upon the edges exposed adjacent the telescopic joint 18, with the result that the thinned ends 19 will be forced under the stop 13 with which all such windows are equipped. Small prongs 21 in the ends of the bed plate willbe forced into the wood of the frame 10 to prevent the bed plate from moving inwardly or outwardly .of the window frame.

The housing aforesaid in essentially an invertedbox for which the bed plate forms a bottom and it is between these two members that the various elements of the guard form the only connection, each extensible unit of the guard bein connected at its respective ends to the Eed plate and the housing.

The various extensible uard units may be classified for purposes 0% description into central, lateral and cross guards and it will be obvious in the light of the following dis closure that any number of additional guard fill embers could be supplied when a large tvindowis to be equipped, the various types of guard members being adapted for use in various combinations to meet all requirements.

The lateral members 22, since they have little space in which to retract, are made, as indicated in a plurality of parts, each being receivable into its mate so as to telescope into a fairly small space, the end parts being provided with pivot elements to receive brackets 23 and 24c upon the bed plate and within the housing respectively. The dimensions of the guard members 22 when contracted are determined by the horizontal distance between their respective top and bottom pivotal points, between which these members must be received when the guard is collapsed. The location of the pivot points in turn, is so chosen that the guard member will effectively block the opening which would exist it only the diagonal or cross guard bars were employed.

The cross members 25, as will be obvious from an examination of Figure 1, are only extensible to a small proportionate degree and are therefore made in only two parts telescopically joined together,this member being likewise equipped with pivot elements which receive the brackets 26 and 27 as indicated in Figures 5,8 and 9.

The central member 28 of the guard elements is of necessity more complicated than the others. It likewise extends between the case and bed plate, to which it is pivoted on brackets 29 and 30 similar to the brackets 26 and 27, but in addition to the telescopic joint 31, I have provided a double hinged joint 32 which can break in either direction so as to permit the central member to fold into its space beside the lateral and cross members in the case as shown in Figure 2 when the guard structure is not in use.

All of the guard members are pivotally connected to the bed plate and case, the pivots for members of the several types be ing disposed in different vertical transverse planes.

I have described the general construction of my device in so far as its guard elements are concerned. It now remains to consider the method of attaching the housing to the rail 150i the sash, since'obviously means or" attachment and detachment must be provided if the guard is to be optionally used, ordispensed with in the window opening. Since it is necessary that the meansof attachment of the case to the rail 15 be inaccessibleto childrens fingers, Ihave provided a lock which is substantially concealed 1within the case and operable only with a rey. 1::

Upon the rail 15 I have, secured two brackets 33 which have an-oilset portion 34 apertured as indicated in Figure 2. The ofiset portion 34 is adapted, when the windew and case are in operative relation, to be receivable in aperture 35 in the outer margin of the top of the case and the aperture in the offset portion 34 of the bracket is so p0si tioned as to register with a spring lock plug 86 which moves longitudinally of a bayonet socket 37 at either end of the case as indicated in Figure 5, the lock plug 36 being provided with a key aperture 88 which will receive any small L-shaped key to retract the plug from the aperture in part 34 of the bracket 33 and if twisted to one side the plug will be locked in released position and the window with the brackets 33 may be raised without carrying the case upward to unfold the guard. If the guard is desired the key can be used to turn the plug 36, release the spring 40 which will force the plug into the apertured bracket 33 and cause the case to respond to any change of position of the rail 15, thereby unfolding the elements of the guard to the extent desired.

It will thus be seen that my guard is never in such a position as to prevent complete closure of the window and the guard itself is always protected by the window when the window is closed. Likewise the V entire guard, with the exception of the brackets 83 which will ordinarily be permanently secured to the window, may be removed bodily from the window by unlocking the case from the brackets 33, and telescopically reducing the length of the bed plate 17.

It will be noted that the various elements of my improved guard do not leave any area of the'window opening exposed for the passage of so large a body as a child and that any number of additional members corresponding to one or another of my three types of such members may be used to increase the efliciency of my device.
