This invention relates generally to a method and apparatus for covering a window opening, more particularly to a lightweight, cost effective and temporary protective cover for a window opening for protecting the interior of a building from external elements.
Window guards and window protectors are well known. They are generally made of a board that is removably mounted to a window to cover and protect the windowpane. Most such window guards or protectors are designed for the purpose of protecting a window from damage during a storm (e.g., U.S. Pat. No. 5,507,118; U.S. Pat. No. 5,335,452; U.S. Pat. No. 5,228,238), intruders (e.g., U.S. Pat. No. 4,972,639), and other harmful phenomena (e.g., U.S. Pat. No. 4,495,978; U.S. Pat. No. 3,485,954, directed to nuclear radiation). Most often, they are designed so as to not disrupt the normal operation of the window or the aesthetic appearance of the window while not in use, and are specifically designed to be on the exterior of the building to protect the window from externally occurring phenomena. Additionally, these examples are generally designed as permanent features of the building; either being permanently installed onto the window frame or building or attaching to permanent fixtures that are secured on the exterior of the building. The window guards thereby are conveniently in place when a disruption occurs. Such systems are not specifically designed to protect the interior of the building in the temporary absence of the window.
Windows frequently need to be replaced on a construction site or when a windowpane becomes broken. Windows are also blown out due to natural disasters such as earthquakes, tornadoes, and hurricanes. A broken windowpane or the absence of a window in an occupied building causes a great deal of disruption to the occupants and creates a mess in the interior. A quick, temporary, and cost effective solution is often necessary. For example, in a residential dwelling, window replacement during a construction job creates a great deal of dust and debris in the interior, often necessitating a complete vacation of the dwelling. The temporary construction also exposes the interior of the house to weather and poses a risk to the security of the occupants. A common fix to the problem is to affix a tarp, plastic sheet, or drop-cloth over the opening until the window is replaced. The temporary makeshift covering is often held in place by staples, masking tape, or nails, often damaging the interior walls. This solution is unsatisfactory for many reasons. For example, plastic sheets often become wind-blown, letting in weather, dust and debris. Furthermore, plastic sheeting does not secure the worksite, making occupants vulnerable during the construction phase. Intruders can easily break in, and pets and children can easily slip out undetected.
Therefore, a need exists in the market for an apparatus and a method to protect a window opening in the absence of a window for the purpose of protecting the interior during repair, for example, during a construction project, where a quick, cost effective and temporary solution is required.
These and other embodiments of the invention will be described in further detail below.
Preferred and alternative embodiments of the present invention are described in detail below with reference to the following drawings:
One embodiment of the present invention is a device for adjustably providing protection of a window opening in the absence of a window. The purpose of this exemplary embodiment is to protect the interior of a building, for example, during a construction project, where a cost effective and temporary solution is required.
An embodiment of the present invention is a window opening protector mountable over a window opening, the window opening protector comprising: a cover element sized to fit over a window opening and an adjustable brace assembly.
In accordance with some embodiments of the invention, the cover element of the window opening protector can be made from pre-cut, or user-cut materials. Examples of materials for the cover element include, but are not limited to cardboard, plywood, or plastic, such as Lexan®. It is contemplated that a cover element may be translucent or opaque, dependent on the user application, and in a preferred embodiment is made of light weight material.
In accordance with some embodiments of the invention, the cover element of the window opening protector can be pre-cut to a standard window opening size. In an alternative embodiment, a cover element can be cut to size by the user using a window frame sizing template. Pre-cut cover elements correspond to commonly used standard sized windows, including, but not limited to: 24″×24″, 36″×36″, 48″×48″, 60″×60″, and 72″×72″. In an alternative embodiment, size templates based on industry standards, window manufacturer (e.g. Milgard®, Pella®), hinge placement (e.g., top/side/bottom), window opening type (e.g., opening in or out), and window classification (e.g., casement windows, picture windows, horizontal sliders, vertical sliders, sliding glass doors, and the like) can be used. The user can utilize a size template to accurately fit the height and width of the opening and to cut a cover element for use with the brace element of this invention.
In an exemplary embodiment, the cover element is cut to a size that fits within the frame of the window opening, such that the cover element can rest on the window sill or frame, and, more particularly, fit snugly against the window prior to the window removal. In this example, a more accurate measurement of the interior frame must be made and allowances made for the frame size and inset. In another exemplary embodiment, the cover element can cover the entire window opening. In operation, the cover element would contact the interior wall covering the entire opening, but not necessarily fit within the recess of the window opening. As can be appreciated, less exact measurement of the window frame itself can be made, and approximate standardized sizing is facilitated by this approach.
In accordance with some embodiments of the invention, the brace assembly can be adjustable in length. For example, the adjustable pole member, an integral element of the brace assembly, can be retractable, telescoping, or have removable sections. The use of extension rods, lightweight extendable and retractable poles, and/or telescoping extension rods or poles are well known for household tools such as vacuum cleaner attachments, and mop handles, and functional construction tools such as painting brush poles, as well as flag poles, sports equipment poles, and the like. Structural configurations and designs have been developed for the fulfillment of countless objectives and requirements wherein a plurality of pieces are fit one within the other, or alternatively connecting end to end, with various positioning and locking means to facilitate the expansion of the rods' length. While these devices fulfill their respective objectives and requirements, the present invention substantially departs from the concepts of the prior art, and in doing so, provides an apparatus primarily developed for the purpose of providing an adjustable brace for a window opening protector, positionable between a cover element and a frictionally engaged foot, to secure the cover element in the window opening.
In operation, the brace assembly, and in particular the adjustable pole member of the brace assembly, is extended by the user to a length approximately equal to the distance from the adjustable foot of the brace assembly to the cover element positioned against the window opening, such that the adjustable pole member and the engaging surface, for example a floor, are at a less than 90 degree angle to each other. Pressure is created on the cover element as the adjustable pole member is extended. Once the cover is securely and snugly in place, the length of the adjustable pole member is correct and the cover element is properly positioned over the window opening.
In accordance with other embodiments of the invention, the brace assembly can be coupled to a mounting element by a mechanism that enables the flat mounting element to adjustably rotate relative to the adjustable pole member. In a non-limiting example, the mechanism can be a ball and socket connection. The mounting element can assume a suitable position (e.g., approximately centrally located) relative to the cover element to press flatly and evenly against the cover element when the brace assembly is in place. The size and shape of the mounting plate is in accordance with the application, and can depend on the materials employed for the cover element.
In accordance with other embodiments of the invention, the brace assembly can be adjusted along its length to accommodate different angles in operation. A variety of lockable hinge mechanisms are known for poles and rods for providing selective pivotal motion, collapsibility, and for locking angular relationships between elements. In a nonlimiting example, the mechanism to adjust the angle can be lockable hinged mechanisms placed along the length of the pole, to secure abutting elements of the adjustable pole member in any desired angular relationships. In one non-limiting embodiment, the adjustable pole member can be adjusted at a lockable hinge along its length to bend around furniture, architectural features, and other obstacles in a typical occupied interior near the window opening wall. The hinge allows workers to affix the cover element over the window opening with the least amount of disruption to the interior fixtures, and provides a quick solution to what otherwise would be a time consuming moving job.
In accordance with still further embodiments of the invention, the brace assembly is attached at one end to an adjustable foot, for example, a swiveling rubber foot, to secure the brace to an engaging surface, for example a floor, at an angle to the window opening, via friction.
In accordance with yet another example of the invention, the brace assembly may include an adjustable pole member that is hollow. The hollow adjustable pole member can be attached to the cover element, such that a vacuum can be applied. In one embodiment, a cover element can be fitted against a newly installed window and a vacuum applied to pressure test the window for leaks. In an alternative embodiment, a vacuum source can be directly attached to the cover element at a connector element on the cover element. In operation, the user can attach an external vacuum source while the cover element is against the window or window opening and apply the vacuum. If the window leaks, or is otherwise improperly sealed, water can be pulled through the vacuum. It is contemplated that the vacuum system can also be applied generally to remove dust and debris at the worksite.
In accordance with still further embodiments of the invention, the cover can include additional reinforcing member that are either horizontal, vertical, or both. The reinforcement members can add further stability to the cover element, thus providing greater protection from the external elements and reinforcing light weight materials that cover window openings.
In accordance with still further embodiments of the invention, the cover element can be made from an adjustable frame element that sizably adjusts, and then is positioned over a flexible cover element material, the cover element conforming to the size of the frame and kept in place in the window opening by the frame.
It is contemplated that in a commercial application, for example, one in which a high volume of standard-sized windows are known (e.g. an apartment complex), the cover element 15 can be pre-cut from any material, as exemplified above, and supplied with a mounting bracket 45 already attached. In an alternative embodiment, gridded templates can also be provided, where standard width and height dimensional sizes for windows are printed as patterns that a user can follow to fabricate a cover element according to their need.
In accordance with further embodiments of the window opening protector assembly 11, in

In operation, and as a first step, the mounting plate 30, can be fixed into position on the cover element 15, by fitting within a mounting bracket 45 on the cover element 15 prior to the coupling to the brace assembly 20. As a second step, the mounting plate 30 can be detachably and rotatably coupled to the adjustable pole member 34 by a coupling mechanism 50, such as, but not limited to a ball and socket mechanism. The receiving socket 52 on the coupling side 47 of the mounting plate 30 receives the ball 54 on a first end 25 of the adjustable pole member 20. In operation, the user places the cover element 15 over the window opening 13 and then attaches the adjustable pole member 34, pressing a second, flat surface 46 of the mounting plate 30 flatly against the cover element 15 and against the window opening 13.
In another exemplary embodiment, as a first step, the mounting plate 30 can be coupled to the adjustable pole member 34 by the coupling mechanism 50, as described above. In a second step, the user can place the cover element 15 over the window opening and in contact with the second, flat surface 46 of the mounting plate, and flatly press the brace assembly 20, now complete with mounting plate 30 and adjustable pole member 34, against the cover element 15 and against the window opening 13. Optionally, the cover element can have a mounting bracket 45 to receive the mounting plate 30 to stabilize the connection between the cover element 15 and the brace assembly 20.
The adjustable foot element 57 attached at the second end 37 of the adjustable pole member 34 frictionally engages the engaging surface 24, for example a floor, at an angle to the window opening 13. In one embodiment, the adjustable foot element has a flat bottom surface, with, for example, a rubber surface, the rubber preventing slipping of the adjustable foot element 57 while in operation. The adjustable foot element 57 is pivotably engaged in relation to the adjustable pole member 34. The pivotablity of the foot element 57 keeps the bottom surface of the foot flush with the engaging surface 24, for example a floor, when the foot element engages frictionally with said engaging surface 24 at an angle to the window opening.

The adjustable pole member 34 may be retractable, telescoping, or include removable sections. In a preferred embodiment, the adjustable pole member 34 can include a plurality of telescoping tubular members (not shown): a first telescoping tubular member having side walls shaped to conformingly mate with a second telescoping tubular member; the second telescoping tubular member being telescopingly mated with said first telescoping tubular member, said second telescoping tubular member being sized and shaped to conformingly mate with said first telescoping tubular member. A holding mechanism, such as but not limited to, aligned bore holes, operate to fix the second telescoping tubular member within the first telescoping tubular member within a range of relative positions between said first and second telescoping tubular members. The length of the pair of telescoping tubular members, when telescoped, can be adjusted to a position within said range and held in such position. A lock mechanism (not shown), such a spring actuated detent, for locking said first telescoping tubular member to said second telescoping tubular member, fixes the length in any of said positions within said range. Pieces can be added and removed according the user's need, each tubular member fitting together as described.
In accordance with other embodiments of the invention, the brace assembly 20 can be adjusted along its length to accommodate different angles in operation. A variety of lockable hinge mechanisms are known for poles and rods for providing selective pivotal motion, collapsibility, and for locking angular relationships between elements. In a nonlimiting example, the mechanism to adjust the angle can be lockable hinged mechanisms 40 placed along the length of the pole, to secure abutting elements 48 of the adjustable pole member 34 in any desired angular relationships.

While the preferred embodiment of the invention has been illustrated and described as noted above, many changes can be made without departing from the spirit and scope of the invention. For example, although the enclosed description primarily focuses on interior use, the method and device of the present invention can be used for external applications. Additionally, many different materials can be used for the invention, depending on the desired use of the invention, only a few of which have been mentioned. Different sizes and shapes of cover element can be used, and pre-cut or template cut cover elements are contemplated for regular practice. The brace assembly can employ different extension means and different locking means to fix the length of the adjustable pole member. A variety of pivotable joints can be used for the mounting plate attachment, and the pole can be hollow or solid, straight or articulated. Accordingly, the scope of the invention is not limited by the disclosure of the preferred embodiment.
