Abstract
A window grill assembly includes a window frame having a window opening therein. A grill frame is positioned on one side of the window opening, and retaining frame is positioned on the opposite side. The grill frame includes one flange which engages the front surface of the window frame, and the retaining frame also includes a retaining flange which engages the rear surface of the door frame. A second grill flange extends into the window opening and engages a second retaining flange also within the window opening. The second grill flange and the second retaining flange are secured together to hold the grill frame, the window frame, and the retaining frame together.
Claims11
A Window grill assembly comprising:
- a window frame having a window perimetric edge defining a window opening, said window frame having first and second opposite faces spaced apart from one another to define a window frame thickness;
- a grill frame having a first perimetric grill flange forming a first grill flange surface and in facing engagement with said first face of said window frame adjacent said window perimetric edge, said grill frame having a second grill flange extending within said window opening between said first and second opposite faces of said window frame;
- a retaining frame having a first perimetric retaining frame flange forming a first retaining flange surface in facing engagement with said second face of said window frame adjacent said window perimetric edge, said retaining frame having a second retaining flange extending within said window opening between said first and second opposite faces of said window frame;
- first alignment means on said grill frame;
- second alignment means on said retainer frame;
- and
- one of said first and second alignment means comprising an alignment rib and the other of said first and second alignment means comprising an alignment groove, said alignment rib being matingly fitted within said alignment groove such that said first and second alignment means cooperate with one another to align said retaining frame in registered alignment with said grill.
A method for assembling a window grill assembly within a window opening of a window frame, said window frame having a window perimetric edge surrounding said window opening and having first and second opposite faces spaced apart from one another to define a window frame thickness;
- said method comprising:
- forming a grill frame having a first grill flange surface lying in a first plane, said grill frame also having a second grill flange extending in a second plane perpendicular to said first plane, said second grill flange having first securing means, said grill frame also having an elongated rib protruding from said first grill flange surface;
- taking a retaining frame having a first perimetric retaining frame flange forming a first retaining flange surface lying in a third plane, said retaining frame having a second retaining flange lying in a fourth plane perpendicular to said third plane, said second retaining flange having second securing means and a groove in said third place for receiving said rib and aligning said grill and retaining frames;
- inserting said second retaining flange into said window with said first retaining flange surface facing toward said second opposite surface of said window frame;
- aligning said rib with said groove and moving the former into the latter such that said grill and retaining frames are guided into alignment;
- and
- moving said grill frame toward said retaining frame to an assembled position whereby said first grill flange is in facing engagement with said first opposite surface of said window frame and said first retaining flange is in facing engagement with said second opposite surface of said window frame, said first and second securing means retentively engaging one another to hold said grill frame and said retaining frame in said assembled position.
