An apparatus for protecting a window or door frame while allowing objects to pass through the window or door frame comprising:
- first and second vertical supports each extending longitudinally from a first end to a second end, wherein the first and second vertical supports are secured between top and bottom horizontal surfaces of a building;
- and
- a center frame supported by the first and second vertical supports between the first end and the second end of the first and second vertical supports, the center frame comprising first and second horizontal beams, first and second vertical beams, first and second diagonal beams, first and second lateral beams, and a horizontal cross beam, each beam longitudinally extends from a first end to a second end;
- wherein the first and second horizontal beams are slidably attached to the first and second vertical supports between the first and second ends of the first and second vertical supports, such that the first and second horizontal beams can be vertically adjusted along the first and second vertical supports;
- wherein the first ends of the first and second vertical beams are connected to the first horizontal beam and wherein the second ends of the first and second vertical beams are connected to the second horizontal beam;
- wherein the first and second lateral beams extend perpendicularly from the second horizontal beam, wherein each of the first ends of the first and second lateral beams is connected to the second horizontal beam and to one of the second ends of the first and second vertical beams;
- wherein each of the first ends of the first and second diagonal beams is connected to the first horizontal beam and to one of the first ends of the first and second vertical beams, and wherein each of the second ends of the first and second diagonal beams is connected to one of the second ends of the first and second lateral beams;
- wherein the first end of the horizontal cross beam is connected to the second ends of the first diagonal and lateral beams, and wherein the second end of the horizontal cross beam is connected to the second ends of the second diagonal and lateral beams;
- wherein the first and second horizontal beams and the first and second vertical beams define a first opening, and wherein the first horizontal beam, the horizontal cross beam, and the first and second diagonal beams define a second opening;
- wherein the first vertical, diagonal, and lateral beams form a first triangle, and wherein the second vertical, diagonal, and lateral beams form a second triangle;
- wherein the center frame is placed within the window or door frame and wherein the first and second openings are provided for allowing objects to pass through the first and second openings and the window or door frame.
