Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
135 words
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.
Claim 2
Dependent Claim
135 words
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.
Claim 3
Dependent Claim
35 words
An imitated jalousie as set forth in claim 1, characterized in that said V-formed cuts are parallel with each other and form a plurality of parallel hinged jalousie portions hingedly joined by said bendable foil.
Claim 4
Dependent Claim
27 words
An imitated jalousie set forth in claim 1 characterized in that said V-formed cuts define obtuse angles and said folded block provides a bow formed jalousie block.
Claim 5
Dependent Claim
35 words
An imitated jalousie as set forth in claim 2 characterized in that said V-formed cuts define angles of more than 90° whereby said parallel hinged jalousie portions may be folded to define acute angles therebetween.
Claim 6
Dependent Claim
29 words
An imitated jalousie as set forth in claim 2 characterized in that said parallel hinged jalousie portions of the jalousie block are glued together thereby providing a solid unit.
Claim 7
Independent Claim
120 words
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.
Claim 8
Independent Claim
120 words
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.
Claim 9
Dependent Claim
25 words
The method set forth in claim 6 wherein said thin bendable foil is glued onto the complete surface of both sides of the base plate.
Claim 10
Dependent Claim
19 words
The method as set forth in claim 6 wherein the thin bendable foil is made of a plastic material.
Claim 11
Dependent Claim
20 words
The method as set forth in claim 6 wherein said V-grooves are cut so as to define an acute angle.
Claim 12
Dependent Claim
33 words
The method as set forth in claim 6 wherein the jalousie block is introduced into and locked within a groove in said frame whereby said jalousie block is fixed in a zigzag design.
Claim 13
Dependent Claim
18 words
The method set forth in claim 6 wherein the V-formed grooves extend in parallel relation with each other.
