Abstract
An imitated jalousie door or shutter including a frame having a jalousie block mounted therein and a method of making such a door. The jalousie block is constructed from a base plate of relatively non-bendable material having a thin bendable foil bonded to the front and back surfaces of the plate. A plurality of parallel V-shaped slots are cut in the front and back surface of the plate through one layer of foil and completely through the thickness of the plate but not through the second layer of foil. The block may then be folded in a zigzag or jalousied relation to be received and secured by the frame. A similar method is provided for forming the frame.
Claims11
An imitated jalousie comprising a frame having a jalousie block mounted therein, said frame having a groove therein, said jalousie block including a base plate having opposed front and back surfaces and being constructed from a strong material which is resistant to bending and a thin foil of a bendable material bonded to each of said surfaces, said block further including V-formed cuts cut in said surfaces, each of said cuts disposed transversely to said groove and extending through the foil bonded to one surface and through the base plate but not through the foil of the opposed surface, said block being folded in a zigzag form and mounted in said groove in the frame, and means on said frame for maintaining said block folded in zigzag form, thereby providing a tight, solid jalousie unit.
A method of manufacturing an imitated jalousie so as to include a frame having a jalousie block mounted therein comprising the steps of covering a base plate on both sides thereof with a thin bendable foil material and bonding said foil thereto, said base plate being formed from a strong material resistant to bending, cutting V-formed grooves at predetermined places alternately on each side of the foil covered base plate, said cuts passing through the foil at the cut side and through the base plate but not through the foil on the opposite side, folding said cut plate into a zigzag design along the cut V-grooves, and securing the folded plate in its zigzag design by means of said frame.
