June 29, 1965 -A Y w; RAUEN l 3,191,242 SIMULATED LouvEREb SHUTTER .Filed Jan. s, 1961 United States Patent O 3,191,242 SIMULATED LOUVERED SHUTTER Math W. Rauen, Oconomowoc, Wis., assigner to Lyf- Alum, Inc., Oconomowoc, Wis., a corporation of Wisconsin Filed Jan. 3, 1961, Ser. No. 80,249 1 Claim. (Cl. 20-63) This invention relates to a simulated decorative louvered shutter.
-It is an objective of t-he invent-ion to provide an improved simulated shutter which is adjustable in length to it any requirement but is exceptionally rigid when assembled. Previously known simulated shutters made of Wood must be made and stocked in a variety of sizes to conform to the height of the windows with which they are used. By making the shutter in two or more sections fabricated of thin sheet metal such as aluminum, it is possible to produce a simulated shutter which will serve all practical needs. The presen-t shutter is an improvement over all simulated shutters heretofore proposed in that its complementary par-ts interlock in all positions to which 4they may be adjusted and, in addition, may be nested for transportation and storage. Not only does the .interlock contribute greatly to the strength of a shutter made of thin and relatively ilexible material such as aluminum, but the cross section ofthe product is also a factor in making it rigid in use.
`In the drawings:
FIG. 1 is a front elevational view of a simulated shutter embodying the invention, portions being broken away.
FIG. 2 is an enlarged fragmentary detail View in perspective showing t-he manner in which the component parts of the simulated shutter are int-erlocked in use.
FIG. 3 is .a fragmentary front elevational view of an extension unit which may be employed when needed.
FIG. 4 is a fragmentary rear elevational view of the lower extremity ofthe uppermost section of the simulated shutter.
The upper element A comprises lleft and right side portions 6 and 7 and a top portion 8 which simulate cor- .responding portions .of a sash. Each of the sash-simulating port-ions 6, 7 and 8 is provided with a marginal flange as shown respectively at 9, 10 and 11. The anges represent the loutside edges of the simulated sash.
The inside edges of the simulated sash are represented by the beveled or inclined surfaces 12, 13 and 14, respectively, these being of less depth from front to rear than the flanges 9, 1t) and v11. Integral wit-h the inclined portions 12, 13 and 14 are the strips `15, 16 and 17 which border the louvers at the sides and the top of the section A.
Each of the louvers 20 has a fiat top portion 21 in a plane which is parallel to but offset from the front surfaces 6, 7 and 8 which simulate the sash. The panel portion 22 of each louver is inclined downwardly and forwardly .so that its lower margin 23 is substantially flush with the llat border str-ips and 16 at each side of the unit. An end wall 24 connects each louver integrally with the border strip 16 at one side and the border strip 15 at the other, the entire unit being stamped in one piece.
The lower unit B, likewise stamped in one piece, is similar to unit A except that .it includes a bottom sashsimulating section 25 which is sufficiently narrower than the sash simulating section 8 at the top of unit A so that the side simulating sections 26 and 27 fit Within the side simulating sections 6 and 7 of unit A, the diference in wid-th being only equal to the thickness of the metal flanges at the sides of the simulated shutters. Of course, it is understood that the upper section A lacks any simulated bottom sash member yand the lower section B lacks any simulated top sash member. An important feature rice of the invention is the provision on the l-owermost louver 200 of the upper unit A of a reversely bent flange 28 which engages the lower margin 23 of one of the louvers 22 of the lower section B when the two sections are assembled 'as shown in FIG. 2.
In order to adapt the device for use with windows of a height greater than the height to which the sections A and B can be extended, a third section C is provided as shown in FlG. 3. This section has a reversely hooked tlange 28 on its lowest louver but it has neither a top sash simulating portion nor a simula-ted bottom sash portion. Its simulated side sash portions 30 and 31 are at a spacing which may be intermediate that of the simulated side sash portions of sections A and B. The metal used is so thin and the deflection required .is so slight that it is readily possible to position the insert section C between the ilanges of section A and ou-tside of the flanges of section B.
Each of the sections A and B is provided with screw holes 32 at the corners of its simulated sash portions. Section A is provided additionally with screw holes at 33 for which there is no counterpart in member B as manufactured. It is intended that suitable registering holes will be provided in member B at the time the sections are assembled. T he screws Aare primarily for the purpose of mount-ing the simulated shu-tters on the wall of a building but they perform the further function of holding the two simulated sections together.
It will be noted that even without the screws 34 the simulated shutter sections are securely interlocked not alone by the hook ange 28 but by the interlocking engagement of the louvers in the lapping portions of the respective units. Referring to the lower part of FIG. 2, wherein the lap is illustrated, .it will be observed that the -fiat por-tions Z1 Aand the inclined panels 22 of the respective louvers are in face contact throughout. The lower margins 35 of the louvers of section B rest upon the top margins 36 of the side panels 24 of section A, the angle of inclination being such that each of the lower margins of the louvers of the top section is securely wedged into an angle from which it cannot escape Without longitudinal displacement of the respective sections. Accordingly, if the sections are anchored at their remote corners against such displacement, they must necessarily remain securely locked together. The same type of interlock is effective between the inserted section C Vand upper and lower sections A and B when the inserted section is used.
Due to the integral stamping of the units to provide the relatively deep section and oblique louvers as shown, the units are rigid to an extent which permits making them of very light-weight material and eliminates any necessity of internal bracing of Iany sort. The absence of internal bracing permits of the nesting of the units A and B, the lower un-it B being inverted and slipped into the unit A in its inverted posi-tion as shown in FIG. 5. This greatly reduces the cost of packaging, shipping and storing the units.
A simulated shutter comprising the overlapped assembly of (a) prefabrica-ted separately incomplete shutter units,
(b) each comprising integrally Prefabricated sash and louver portions,
(c) a part of one unit overlapping a part of the other unit and being longitudinally adjustable with respect to one .another in a direction transverse to said louvers to adjust the overall length of the assembly,
(d) the louvers of each unit extending to the overlapped ends thereof,
(e) the exposed ends of said uni-ts respectively having top and bottom sash portions beyond said louvers,
(f) and mean-s for interlock-ing saidunits in any one of a plurality of overlapping positions in which all Iof the louvers in the overlapping part of one unit register in face oon-tact with corresponding louvers in the overlapping part ofthe other unit,
(g) whereby the overlapped assembly of said units simulates a single unitary shutter with evenly spaced louvers, regardless of the degree of overlap of the respective units,
('h) each louver of one unit having a flange integrally connecting i-ts end with a sash portion of said one unit,
(i) said flange having an edge transverse tothe edge of the corresponding louve1 of the other unit,
(j) said flange edge and louver edge abutting to define registration of said louvers, at least one louver of one unit having a marginal hook flange engaged in the. assembly of said units with a corresponding margin of alouver of t-he other unit.
