ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the field of fenestration products including windows and doors. In particular, the invention is concerned with a fenestration product having a plurality of installation fins rotatably coupled with the mounting surfaces of respective frame members of the product.
2. Description of the Prior Art
Prior art fenestration products, such as doors and windows, include a frame having frame members such as head, sill and jambs with each frame member having an installation fin, usually composed of aluminum. One edge of a fin is attached to the exposed surface of a respective frame member. The fin is positioned flush against the frame member and extends toward the inboard side of the product.
In order to install the product in a building opening, the fin is bent so that it extends outwardly from the frame member. The product is then positioned in the building opening from the exterior side. One person must hold the product in place from the outside while a second person shims the product for level and plumb from the interior of the building. The fin is then nailed to the framework surrounding the opening in order to secure the product in place.
The requirement for two people to install a fenestration product represents inefficient use of labor and increases the installation cost of the product.
SUMMARY OF THE INVENTION
The present invention solves the prior art problems mentioned above and provides a distinct advance in the state of the art. In particular, the fenestration product hereof enables one-person installation thereby increasing labor efficiency and decreasing installed cost.
The preferred fenestration product of the present invention includes a fenestration structure having a frame with frame members presenting an outboard side, an inboard side, and a mounting surface therebetween, and includes an installation fin presenting a coupling crook rotatably coupled with the frame member between the outboard and inboard sides. The fin is rotatable between an extended position in which the fin extends outwardly from the mounting surface and a retracted position in which the fin is positioned substantially flush against the mounting surface and extends toward the outboard side. The fenestration structure and fin cooperatively present a configuration allowing positioning of the product in an installed position in a building opening with the fin in the retracted position, and allowing subsequent rotation of the fin to the extended position while the product is in the installed position in the building opening.
In preferred forms, the coupling crook of the fin presents a J-shaped configuration and is snap fitted in a complementally configured coupling slot defined in frame member. It is also preferred that the fin substantially cover the outboard section of the mounting surface between the coupling crook and the outboard side of the frame member. Other preferred aspects of the present invention are disclosed herein.
