8 Claims. (Cl. 20-71) The inventionrelates to window guards and specifically to guards for casement windows.
The unguarded, open casement windows of large metropolitan apartment houses are principally casement windows which have proven to be prolific causes of accidents, many fatal, which occur when infants, sometimes adults, fall from the open windows.
Various expedients have been employed to lessen or prevent these accidents but few have proven efficacious, some of the inherent disadvantages being difl'iculty of installation, high cost or other drawbacks.
One of the objects of my invention is the provision of a window guard which will prevent accidents and can be quickly installed on a window casement with the simplest of tools, and is virtually tamper-proof.
Another object comprehends a window guard which requires no mechanical aptitude to install.
Still another object contemplates a window guard, the components of which can be mass produced and sold at low cost, within the budgetary requirements of virtually every apartment dweller.
I provide a window guard which for the minimum investment will protect every member of the family.
Briefly described, the invention comprises a pair of clamps, attachable at opposite sides or top and bottom of a casement window and adjustable when necessary, for use in conjunction with a bar held by the clamps to cross the window opening and prevent persons from falling therethrough. The clamps are provided with threaded bolts for tightening the clamps to the window casement, and a centrally positioned threaded bolt member for tightly securing the bar in the clamp, said bar insertable in each clamp in an opening or aperture therein. And I contemplate that one or more than one bar may be employed, held by one or more pairs of clamps, or a plurality of horizontal bars sustained in spaced relationship by vertical bars, and vice-versa.
in the drawings:
Figure 1 is a top plan view showing the invention in use;
Fig. 2 depicts an exploded perspective view;
Fig. 3 is a cross-section taken along the line 33 of Fig. 1;
Fig. 4 is a cross-section taken along the line 4-4 of Fig. 1;
Fig. 5 is a front plan view of a modified form schematically showing a round or a hexagonal bar being used;
Fig. 6 is a cross section of a modified form of the invention taken along the line 6-6 of Fig. 5;
Fig. 7 is a plan view of another modification.
Referring to the drawings, the clamps 5, of which a pair or pairs are required, dimensioned and formed alike, may be produced from a blank of lightweight material, such as aluminum, magnesium, alloys thereof, or from any other metal or material having the desired inherent strength and rigidity. And in reference to said clamps, like numerals are intended and do refer to like parts.
Midway of the back and closer to flange 7 than to flange 6, I provide an opening 9 which in the preferred embodiment of the invention defines a circular aperture, although it may be as suggested in Fig. 5 shaped to lit the peripheries of any bar stock other than round. Additionally, I contemplate using flat steel bent to any desired shape to fit the aperture, tube stock, both square, hex and round may be used, plastic stock or wood or any material having the desired strength.
Threaded through the opposite ends of flange 7, are bolts 10, which when threaded home, impinge against flange 6 and hold between their lower terminals and one face of the flange, the easement C of a window.
Centrally located with respect to flange 7, toward back 8, and threaded vertically through said flange is bolt 11, which, as illustrated in Fig. 3, secures bar 12 in clamp 5 when said bar is thrust through the aperture 9 in back 8 of said clamp.
In Fig. 5 is illustrated a modification wherein the.aperture is shaped with a semicircular-like top 13, having shoulders 14, and the opening 15 is defined-extends between flanges 16 which also extend at right angles from the back 17 and parallel to each other. In this embodiment threaded bolts 18 are threaded through upper flange 19 and bolt 20, threaded through said flange, causes bar 12 to be held against casement C when the bolt is tightened. A capital advantage of this modification is that this aperture is capable of taking bars of different peripheral configurationtwo different ones being illustrated positioned.
As is readily understood, the bolts illustrated in the clamps are fitted with Allen type heads, and the well known Allen wrench can be employed to quickly tighten the clamps 5 in the desired position on the casement window, and the same wrench used to tighten bolt 11 against bar 12. One advantage of using an Allen head is to preclude tampering with the mounted guard, and any unwanted loosening of the clamps or bar by children or others. But other types of heads may be used. One advantage of threading bolt 11 through flange 7 on the side nearer to back 8 is that there is less strain on the diverging angle between flange 7 and back 8 when the bolt 11 is tightened against bar 12. Bar 12 may be positioned horizontally or vertically, as shown in Fig. 1, and, of course, the location of clamps 5 may be higher or lower on the casement than the location depicted in said Fig. 1. Positioning the window guard is a matter of choice, the end result being maximum safety for the entire household. And, as before stated, instead of one bar, there may be a plurality of bars employed, secured by additional pairs of clamps 5. Further, another advantage of providing the apertures in the said clamps is that the bars are removable for window washing and other purposes without having to remove the clamps.
Finally, as shown in Fig. 7, I contemplate using a guard comprising, for example, horizontal bars 21 and 22 held fixedly spaced apart by vertical bars 23, 24, 25 welded or otherwise secured to bars 21 and 22. This guard is positioned at any desired place on the window, by placing the clamps where required.
The components, as mentioned before, may be mass produced and for a modest sum a window guard may be bought for every window in an apartment. While a single casement window is shown, the guard is adaptable to double casement windows, and, for that matter, any type window having a casement to which clamps 5 are afiixable.
I reserve the right to make such changes or modification more thanone bar.
3 tions as may come within the scope of the appending claims.
For example, the clamps 5 may be made of greater overall length, and more than one aperture may be provided so that a singlepairof clamps can be used to posi- And other modifications are, of course, within the scope of the invention.
