ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a window frame, and more particularly, to the type that includes an internal channel for receiving security-fastening members.
2. Description of the Related Art
Many designs for window frames have been designed in the past. None of them, however, includes internal channels in the outer frame assemblies for receiving security-fastening members therein.
Applicant believes that the closest reference corresponds to U.S. patent application Ser. No. 09/885,603 filed on Jun. 20, 2001 by the applicant of the present invention for a keyed window assembly for garage doors. The keyed window assembly includes resilient male (
30
) and female (
40
) frame members that are brought towards each other to sandwich the borders of the door panel (
20
) defining the window opening and the cooperatively dimensioned transparent panel (
50
). The male frame member (
30
) includes a peripherally extending leg member (
31
) that is lockingly received within a cooperative channel notch (
51
) on the transparent panel (
50
). Fastening members (
60
) are used to keep the male (
30
) and female (
40
) frame members securely against each other. However, it differs from the present invention because the present invention includes inner peripheral surfaces with channels having a T-shape cross-section defining a longitudinal cavity and a neck, the former being wider than the latter. The cavity is intended to slidably receive the nuts when the user cooperatively positions the fastening member through the neck, securing the outer member, the inner frame, the transparent member and the panel.
Other patents describing the closest subject matter provide for a number of more or less complicated features that fail to solve the problem in an efficient and economical way. None of these patents suggest the novel features of the present invention.
SUMMARY OF THE INVENTION
It is one of the main objects of the present invention to provide a reinforced window frame that withstands substantial wind loads and object impacts.
It is another object of this invention to provide a burglar resistant window frame.
It is still another object of the present invention to provide a window frame that can be readily installed in a panel opening.
It is yet another object of this invention to provide such a window assembly 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.
