Description




FIELD OF THE INVENTION




The present invention relates to a device for protecting windows and doors from breakage and damage during severe storms, including hurricanes.




BACKGROUND OF THE INVENTION




Presently, home and business owners who seek to minimize the damage caused by severe storms have few options for protecting windows and doors. Two of these options are very expensive and require time-consuming installation. One such option requires the removal of the pre-existing window and frame and replacement with a storm window having a frame with a slot for the insertion of a properly-sized piece of plywood. Another such option requires the installation of a storm shutter for each window, either a hinged shutter or a metal shield which is unrolled to cover the window. Many of the other devices for protecting windows require making holes in the window frame for insertion of braces or anchors. Some are cumbersome or difficult to install.




The least expensive option is buying and cutting pieces of plywood and nailing a piece of plywood over each window. However, after the storm has passed, the removal of the plywood leaves nail holes behind. Finally, some people simply apply tape to windows so that glass shards are not blown everywhere if the windows break during a storm. Needless to say, tape offers little or no protection from the storm itself.




A need presently exists for an inexpensive device which can be installed on short notice, without pre-installation, nailing, or screwing.




SUMMARY OF THE INVENTION




The present invention overcomes the disadvantages of existing options for protecting windows and doors during violent storms. The window covering devices herein disclosed can be easily installed, on short notice. They can be used over and over again, leaving no nail or screw holes in window frames.




The locking assemblies can be sold in hardware stores. The plywood or other material is sold separately. (Plywood can be used from previous storm alerts). The panels that will cover the windows do not need to be cut precisely to size; they need only fit within one-half inch of the sill, head and sides of the window frame. Alternative embodiments of the locking assemblies are disclosed: one can be fastened to the wood with a wrench or pliers; another can be slipped over the edge of the panel, requiring no drilling or fastening.




A primary object of the present invention is to provide a window covering device which may be easily installed and removed.




Yet another object of the present invention is to provide a window covering device which can be assembled and installed by ordinary homeowners.




Still another object of the present invention is to provide a window covering device which can be installed in metal or brick frames, where nailing or screwing is not possible.




A further object of the present invention is to provide a window covering device which can be used on non-standard sized and shaped windows, as well as doors.




One more object of the present invention is to provide a window covering device which leaves no nail holes or screw holes in a window frame.




A still further object of the present invention is to provide an effective window covering device at a substantially lower cost than storm windows or shutters.




Several embodiments of the invention are described with reference to the following drawings.

FIGS. 5A-5C

show the operation of a locking assembly


13


. In its unlocked position, shown in


5


A, one end of the lever arm


22


abuts an end of locking arm


26


. The pivoting of lever arm


22


has caused the locking arm


26


to pivot, stretching the spring


31


. The opposite end of lever arm


22


has been inserted into catch


34


, preventing further movement of either the lever arm


22


or the locking arm


26


. The curved end


29


of the locking arm


26


and the rubber stopper


30


do not extend past the side of the base plate


20


. In order to complete installation of the wood covering device


10


in a window frame


11


, as shown in

FIG. 1

, the edge of the wood panel


12


having the gasket


14


is positioned on the left side of the window frame


11


. The side of the wood panel


12


having the locking assemblies


13




a


,


13




b


is then pushed into place along the right side of the window frame


12


.




As shown in

FIG. 5B

, the end of the lever arm


22


has been released from the catch


34


, allowing it to pivot in the direction of the arrows about lever arm pivot point


23


. As the lever arm


22


pivots, the contraction of spring


31


causes the locking arm


26


to pivot in the direction of the arrows about locking arm pivot point


27


. The pivoting movement of the locking arm


26


causes the curved end


29


of the locking arm


26


to extend past the side of the base plate and contact the window frame


11


.





FIG. 5C

shows the locking assembly


13


in its final locked position. The lever arm


22


and the locking arm


26


are in parallel alignment, prevented from further spring-induced pivotal movement by stop


25


. The rubber stopper


30


covering the curved end


29


presses firmly against window frame


11


, and spring tension holds the window covering device


10


in place.




Removal of the panel


12


after a storm is quick and easy: the lever arm


22


of each locking assembly


13


is pivoted, causing the locking arm


26


to pivot, and causing the curved end


29


of the locking arm


26


to move away from the window frame


11


; the rubber stopper


30


will no longer press against the window frame


11


, and the panel


12


can be pulled out. The metal catch


34


holds the lever arm


22


in an unlocked position.





FIGS. 6

,


7


, and


8


show alternate choices for installation.




In

FIG. 6

, the window covering device


10


has been installed in the window frame


11


on the exterior-facing side of a window


40


. Each locking assembly


13


pushes against the right side


41


of the frame


11


, while the rubber gasket


14


pushes against the left side


42


of the frame


11


.




To accomplish the installation shown in

FIG. 7

, the window must first be opened. Someone inside a dwelling can slip the window covering device


10


through the window


40


and rest the gasket


14


against the outer window frame


43


on the exterior side of the window


40


.




As shown in

FIG. 8

, the window covering device


10


can also be installed on the inner window frame


44


on the interior side of a window


40


if, for instance, burglar bars


45


are present, the window


40


does not open, or the exterior side of the outer window frame


43


is inadequate to hold the window covering device


10


in place. While this installation choice does not protect the window glass, it affords protection from flying debris' entering the dwelling, and from theft or looting.
