Abstract
A window assembly for garage doors with hingedly mounted panels. The assembly includes resilient male and female frame members that are brought towards each other to sandwich the borders of the door panel defining the window opening and the cooperatively dimensioned transparent panel. The male frame member includes, adjacent to its peripheral inner end, a peripherally extending leg member that is lockingly received within a cooperative channel notch on the transparent panel. The engagement of the leg member to the channel member permits certain deformation to be transmitter to the resilient male and female frame members. Fastening members are used to keep the male and female frame members securely against each other.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a window assembly, and more particularly, to a keyed window assembly for garage doors.




2. Description of the Related Art




Many designs for window assemblies for garage doors have been designed in the past. None of them, however, include the features claimed herein that permit the present invention to withstand high winds and flying objects.




Garage doors typically include a number of hingedly connected panels that are moved from a vertical position to a horizontal overhead position over tracks. The window assemblies are typically positioned on the uppermost panels. They are designed to enhance the aesthetic appeal of the door while permitting daylight through. However, the window assemblies used in conventional garage doors include frames that cannot withstand high winds, such as those that develop in certain areas, such as South Florida. Local construction codes include wind tests that require reinforcements of these window assemblies and many times these added structures detract from the aesthetics of the window design.




The advantages of the present invention, as it will be more fully explained in the following paragraphs, provides for a simple window assembly that includes frame members that can be readily installed around the edges of the aperture defining the window. The claimed window assembly includes a transparent panel with a peripheral groove that cooperatively receives the edge of the male frame member. The assembly is thus capable of retaining the transparent panel while absorbing the impact energy of high winds and flying objects.




It has been found that prior art window assemblies are typically rigid and the impact energy exposes its components to stress and shear forces that cause them to break. The present invention partially absorbs the impact energy through the limited deformation of its components. The transparent panel of the window, however, is still kept in place thereby preventing any wind or objects to come inside the protected premises or a breakaway situation.




SUMMARY OF THE INVENTION




It is one of the main objects of the present invention to provide a window assembly for garage door panels that is capable of withstanding high winds and flying objects by in part resiliently deforming its structure to absorb the impact energy.




It is still another object of the present invention to provide a window assembly for garage door panels that is volumetrically efficient and does not detract from its aesthetics.




It is yet another object of this invention to provide such a device that is inexpensive to manufacture and maintain while retaining its effectiveness.




Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring now to the drawings, where the present invention is generally referred to with numeral


10


, it can be observed that it basically includes garage door panel


20


, male (interior) frame member


30


, female (exterior) frame member


40


, transparent panel


50


and fastening member


60


. Male and female members


30


and


40


are brought towards each other to sandwich panels


20


and panel


50


along their respective and cooperative border areas. The engagement of resilient frame members


30


and


40


to panel


50


permits the absorption of the impact energy generated by wind and flying objects through the partial deformation of panel


50


and members


30


and


40


.




As best seen in

FIGS. 2

;


3


and


4


, male frame member


30


has resilient characteristics and inner and outer longitudinal ends


32


and


36


, respectively, and both extend peripherally around member


30


. End


32


has a longitudinal protuberance


33


extending inwardly towards the interior of the protected dwelling. Protuberance


33


is intended to enhance the structural integrity of male frame member


30


and it is formed on the inner surface


30


′ of member


30


. Opposite to protuberance


33


, and engaged to longitudinal peripheral edge


52


, there is a longitudinally extending leg


31


from outer surface


30


″. Adjacent to end


36


, at predetermined positions, there are through openings


37


that permit self taping fastening members


60


to go through. Peripheral channel


39


extends adjacent to end


36


and co-acts with peripheral raised portion


48


to sandwich panel


20


biting it with fastening members


60


, as shown in FIG.


4


.




Female frame member


40


also has resilient characteristics and inner and outer longitudinal ends


42


and


46


, respectively. End


42


includes a peripheral notch


43


on inner surface


40


′ extending longitudinally at a predetermined distance and parallel to end


42


. Outer longitudinal end


46


coincides substantially with end


36


. Outer surface


40


″ may include ornamentary designs. Peripheral notch


47


extends longitudinal inside raised portion


48


and it is designed to receive sealant


49


, as best seen in FIG.


5


.




Transparent panel


50


has cooperative dimensions, larger than aperture


22


in panel


20


, that extend beyond inner ends


32


and


42


but stay within outer ends


36


and


46


, as shown in

FIGS. 2

;


3


and


4


. Peripheral groove


51


extends parallel to peripheral edge


52


of panel


50


. Groove


51


cooperatively and lockingly receives leg


31


. Upon the application of impact and wind forces on panels


20


and


50


, they are allowed to deform resilient male and female frame members


30


and


40


while maintaining the engagement of leg


31


and groove


51


. This mechanism has been the key to bear the extreme force applied at wind and impact testing laboratories. Upon release of these forces, the energy stored in members


30


and


40


is also released bringing the structure back to its at rest configuration.




The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
