Abstract
A storm resistant device for a window that has a window frame enclosing at least one sash slidingly and pivotally mounted therein. The sash has side rails and the frame has vertical jambs that engage the side rails of the sash to raise and lower and pivot the sash. The storm resistant device comprises a first elongated bracket having a substantially Z-shaped cross section with two end segments and a middle segment connecting the two end segments. The middle segment is connectable to the side rails of the sashes with one of the end segments extending outward from the sash toward an adjacent jamb. There is a second elongated bracket having a substantially L-shaped cross section with two legs, one leg of the bracket adapted to be mounted to the jamb with a second leg of the L extending toward an adjacent side rail of the sash. The first and second brackets are mounted to the frame and sash, respectively, so that when the sash is closed, the one end segment of the first bracket interlocks with the second leg of the second bracket and prevents the sash from pivoting when pressure is applied to the sash.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This invention relates to a bracket for use on a sash-type window. In particular, the invention relates to a bracket that is mounted on a pivoting sash window that prevents the window from pivoting during storms and high winds.




2. The Prior Art




One of the improvements in window technology in recent years is the development of sash type or “double hung” windows in which each half of the window pivots inward to facilitate cleaning. This way, the outer surfaces of the window panes can be cleaned from inside the building. While this has been a great convenience for many, it has also posed a hazard for some, especially those people inhabiting storm-prone areas. This is because in high winds, the sashes of the windows tend to become disengaged from the frame and pivot inward, thus opening the window and increasing the risk of damage to the window and to the home.




One solution to this problem is to specifically construct a storm-proof window for these areas. Such a solution is posed by U.S. Pat. No. 5,560,149 to LeFevre. However, this does not assist those people who have conventional windows already mounted in their homes, and who do not want to or cannot replace the windows entirely.




SUMMARY OF THE INVENTION




It is therefore an object of the present invention to provide an after-market device that prevents sash-type windows from blowing inward during a storm.




It is another object of the invention to provide such a device that permits normal sliding and pivoting of the window.




It is a further object of the invention to provide a such a device that is simple and inexpensive to manufacture, as well as easy to install.




These an other objects of the invention are accomplished by a storm resistant device for a window that has a window frame enclosing at least one sash slidingly and pivotally mounted therein. The sash has side rails and the frame has vertical jambs that engage the side rails of the sash to raise and lower and pivot the sash. The storm resistant device comprises a first elongated bracket having a substantially Z-shaped cross section with two end segments and a middle segment connecting the two end segments. The middle segment is connectable to the side rails of the sashes, with one of the end segments extending outward from the sash toward an adjacent jamb. There is a second elongated bracket having a substantially L-shaped cross section with two legs, one leg of the bracket adapted to be mounted to the jamb, with a second leg of the L extending toward an adjacent side rail of the sash. The first and second brackets are mounted to the frame and sash, respectively, so that when the sash is closed, the one end segment of the first bracket interlocks with the second leg of the second bracket and prevents the sash from pivoting when pressure is applied to the sash.




The brackets are preferably mounted to the window components via screws threaded through holes in the brackets. Each bracket is preferably about three inches in length, but other dimensions are also effective. The preferred material for the brackets is steel, but other materials such as aluminum, brass or any other strong material are suitable as well.




To form an effective interlocking arrangement, the second leg of the second bracket is approximately one inch long, which creates a strong lock against any counterforces caused by wind gusts against the window.




The first bracket preferably has a ridge extending along its length, and positioned at approximately a central point of the middle section. The ridge is adapted to securely position the first bracket within the jamb without play.

FIG. 2

shows a side view of the bracket shown in

FIG. 1

;





FIG. 3

shows a top view of a second bracket used with the device according to the invention;

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring now in detail to the drawings and, in particular,

FIGS. 1 and 2

, there is shown a first bracket


10


of the device according to the invention. Bracket


10


is substantially Z-shaped, having a first leg


11


, a middle leg


12


and a third leg


13


. There is a ridge


14


extending the length of bracket


10


and running parallel to first leg


11


, to create a more secure mounting when bracket


10


is mounted to a window sash. Bracket


10


is preferably about 3 inches in length, but shorter or longer brackets will also work.




The other component of the device according to the invention is shown in

FIGS. 3 and 4

, which shows the second bracket


20


. Bracket


20


is substantially L-shaped and has a first leg


21


connected to a second leg


22


. Second bracket


20


is also about 3 inches in length, but other dimensions could also be used. It is preferable if both the first and second brackets are the same length, because the device only works to the extent the two brackets interlock with one another.




Bracket


20


is mounted to a window frame via screws


29


threaded through holes


23


, and bracket


10


is mounted to a window sash via screws


19


threaded through holes


15


(shown in FIG.


5


).





FIGS. 5 and 6

show brackets


10


and


20


as they are mounted to a double-hung sash window


50


having a sill


55


, to prevent the sashes from pivoting inward during strong winds. Bracket


10


is mounted to the vertical side rails


52


of upper and lower sashes


53


and


54


so that leg


13


extends outward toward window frame


57


. Bracket


20


is mounted to the vertical jamb


51


of window frame


57


so that leg


22


of bracket


20


extends inward toward sashes


53


and


54


. This way, when the sashes are closed, leg


13


of bracket


10


and leg


22


of bracket


20


interlock and prevent any pivoting movement of the sashes when they are hit by wind gusts from the direction of the arrows shown in FIG.


5


.





FIG. 6

shows a perspective view of window


50


with brackets


10


and


20


mounted thereon. Sashes


53


and


54


can still be pivoted for cleaning by raising the sash to a point where brackets


10


and


20


do not connect and then pivoting the sash outward. Brackets


10


and


20


are very inexpensive to produce and are easily installed via screws, and can prevent costly damage during a storm.




Accordingly, while only one embodiment of the present invention has been shown and described, it is obvious that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
