ABSTRACT:
TECHNICAL FIELD
This invention relates to devices for attaching window wells to buildings, and more particularly, to a window well clip to be utilized with a removable window mold for attaching a window well to a building.
BACKGROUND ART
The use of window wells around windows in houses-and in buildings is well known. Generally, two different methods have been used to attach window wells to the area of the building surrounding the windows. The choice of which attachment method to use has typically depended upon the type of window mold used to form the window opening itself. Two broad types of window molds are used in forming window openings: permanent window molds and removable window molds.
Permanent window molds are molds which remain permanently embedded in the concrete which was poured around the mold to form the window opening. In other words, the permanent window mold actually becomes a part of the building itself. When permanent window molds are used, the molds themselves often have clips or brackets built into the mold. Window wells may then be bolted directly to the clips or brackets to attach the window wells to the area around the window. This method is very effective, but it is expensive to utilize because each window opening requires its own mold.
In order to avoid the costs of using a permanent mold for each individual window opening, removable molds are sometimes used. Removable molds are designed so that concrete may be poured around the molds, and the molds may then be removed after the concrete has set. Clearly, this is cheaper than using permanent molds, as a single mold may be used to form a large number of window openings. However, conventional use of removable molds leaves unsolved the problem of attaching the window well to the building. This attachment has typically been accomplished by using a nail gun to nail the window well to the concrete, or by use of a drill to create holes in the concrete to allow bolting the window wells to the concrete. Drilling holes in concrete or use of nail guns to attach window wells to concrete is difficult and time-consuming. There is thus a need for an approach which provides the simplicity and ease of use of permanent molds, with the cost effectiveness of removable molds.
DISCLOSURE OF THE INVENTION
In accordance with this invention a window well clip is provided for use with a removable window mold which forms a window opening when concrete is poured around the mold and the mold is removed. The clip includes a first face and a second face intersecting with the first face, typically at an obtuse angle. The clip has a hole in the first face for receiving a bolt, with a protective sheath aligned with the hole for receiving a bolt. A boss is provided for removably attaching the clip to the window mold such that when the window mold is removed from the set concrete the clip remains embedded in the concrete to allow attachment of a window well to the clip. Attachment is accomplished by backing out the bolt from the clip, inserting the bolt into a slot on the window well, and then tightening down the bolt to secure the window well in place against the building.
In veiw of the foregoing, several advantages of the s present invention are readily apparent. A window well clip is provided which is cheap and yet effective in attaching a window well to the area around a window. The clip is easy to use, especially when compared to conventional methods of nailing or bolting window wells directly to concrete. The clip is as easy to use and as effective as conventional brackets built into permanent window molds, yet costs only a fraction of the cost of a permanent mold to use.
Additional advantages of this invention will become apparent from the description which follows, taken in conjunction with the accompanying drawings.
