United States Patent O 3,254,207 REFLECTING DEVICE Ross Lowell, 175 W. 13th St., New York, N .Y. Filed June 4, 1963, Ser. No. 285,302 6 Claims. (Cl. 24U-103) and television industries, much of vthe time it is necessary to go yon location out-of-doors to photograph desired subjects. In such instances it is necessary for the photographer to use reflectors to effect the desired lighting rfor photographing the subject and/ or background. To date, the known reflector constructions tfor such purposes have been relatively large, heavy, bulky, cumbersome devices which :are particularly diicult to ship and/or transport. The size, shape, and construction of the known reiiectors of the type to which the invent-ion relates were particularly difficult and expensive to transportv by air when time was of lthe essence. Further, the storage of prior art reiiectors, 'when not in Iuse, has been a chronic problem due to ltheir bulk.
Therefore, it is an object of this invention to provide a readily portable reflector which is light in weight, and which can be readily knocked ldown land packaged so as to occupy a minimum of shipping and/ or storage space.
It is another vobject to provide an improved ree'ctor which .can be readily adjustable to provide 4the reflecting surface required tfor lighting a given subject.
Still another object is to provide a novel frame con.-V
struction for supporting -a relecting surface in Ia manner for readily effecting a 'variance in the curvilinear surface of the reflector.
Still another object is to provide a readily knock-down reflector device which can be readily lassembled and disassembled without the need of any tools in a minimum of ltime and with =a minimum of effort.
In accordance with this invention, the above objects, and other features and advantages are atta-ined by a redector device comprise-d essentially of a readily foldable ree'cting surface supported in the assembled position thereof between la pair of holder rframe members connected yby a means for ladjusting the spacing between the frame holders so as to vary the curvilinear surface of the reflector. Essentially the reflector comprises a plurality of resilient backing slats ydisposed in side-by-side relationship Iand which fare joined together by a sheet of flaccid material. IOne surface of the tliaccid materialis formed to function as a reiiecting surface as by metalliz# ing. Accordingly, -the reflector can be readily lrolled or folded in the knock-'down position thereof into a com pact roll.
Means in the lform of Ia pair of spaced apart holders define the frame for supporting the reflector in the assembled position thereof. Means for adjusting Ithe spacing between the frame holders is provided whereby the degree of curvature imparted to the reflector positioned between holders can be rvaried in accordance with the llighting intensity and spread or coverage.
A feature 'of this invention resides in the provision in which the reflecting `device is relatively simlple in construction, can be inexpensively produced, land is positive varied to increase the area covered by the re'ected light -or -to reduce its intensity when working at close range or whenonly relatively little reiiected illumination is required.
lOther ifeatures `and advantages will become more readily apparent when considered in connection with the accompanying `description and drawings, in which:

in operation. Another feat-ure resides in the improved the curvilinear surface of the reflector can be readily .mark Mylar.
Referring now to the drawings in detail, there is shown in lFIGS. 1 to 4 an embodiment of -the instant reflecting device `Ill. It compri-ses essentially a reflector 111, a :frame #12 for supporting Ithe reflector in `the assembled position thereof, and a means i13 for varying the curvature of the reflector 11 as may be required to effect the proper lighting of a given subject to be photographed.
Essentially lthe reiiector 11 comprisesV a plurality of resilient or yflexible backing slats '14 which are arranged in adjacent or contiguous and preferably 'abutting sideby-side relationship. Preferably the backing slats |14 may be formed 4of plastic, ialuminum or -other suitable light weight resilient material lthat `can be readily 'flexed or bowed. Secured to one side of the respective slats F14 Iis a sheet of Iliaccid material l15 which serves to hinged-ly connect or join the respective slats 14 together. The sheet of material l15 may be of any ilaccid `sheet such as, for example, polyethylene sheet, polypropylene sheet or preferably polyester sheet such as that sold under the trade- Accordingly, the `outer surface -15A of the sheet is formed -so as `to be smooth to provide a reflective surface, 4the inner surface of the sheet preferably Ibeing me-tallized in either event. With the construction described, it will lbe noted that the reflector f1f1 can be readily folded or rolled as shown in FIGS. 3 and 3A in the knock-down position thereof to define Ia compact roll which is polygonal in shape. As used herein a smooth surface is one which is either optic-ally :flat or is slightly roughened -or patterned las by embossing so as to give a slightly light diffusing effect.
A frame means 112 is provided for supporting and holding rigid the reflector V11 when in use. As shown the Iframe means 12 includes `a pair of opposed holders d6 and 17. /Each holder is provided `with a longitudinally extending ychannel shaped portion 16A, |17A to dedine a slot 18, 19. Connected to the rear ange 16B, 17B of the channel shaped mernber.16A, 17A is a co-extensive flange 20, 21, respectively.
The Width of the slots 18, 19 in the respective holders V16, 17 is sufciently wide to receivesnugly the longitudinal sides of the reflector 11. =It will be noted, as seen in FIG. l, that the slats 14 forming the backing for the reflector sheet 15 extend transversely between the respective holders 16, 17, with the ends thereof received in the respectiveslots 18, 19. Thus it wil lbe noted that to assemble the device, the ends of the reflector 11 need be simply inserted into the slots 18, 19 of the respective frame holders 16, 17. i
Means for securing the frame holders 16, 17 and for Patented May 31, 1966 adjusting the spacing therebetween is provided. The means includes a fixture 22, 23 which is connected to the flange 20, 21 of the respective holders 16, 17 intermediate the ends thereof, and preferably at the mid-point thereof. Each fixture 22, 23 is defined as `a bent plate member having a vertical portion 22A, 23A secured to flange 20, 2'1 and an outwardly bent portion 22B, 23B. The outwardly bent portions 22B, 23B have formed in their respective ends a notch 25, 26 respectively.
In the form of the invention shown in FIGS. 1, 2 and 4, an adjusting tie bar 24 is detachably connected between fixtures. As shown the end portions of the tie bar 24 are detachably received in the notches 25, 26 of the respective fixtures 2f2, 23. A pin 27 extended through one end of the bar y24 serves to maintain its respective end in position in the notch 25 of the fixture `22. The other end of the bar 24 has rotatably connected thereto a camming lever or dog 28. As shown the bar 24 is positioned in the respective fixtures so that the stop pin 27 and camming lever 28 are disposed outboard of their respective fixtures 22, 2'3.
Referring to FIG. 2, it will benoted that the reflector 11 can be provided with a curvilinear surface by reducing the spacing between holders 16, 17. This is readily attained by pivoting the camming lever 28. The camming surface 28A of the lever 2S is specifically shaped so that by pivoting the same in the direction indicated by the arrow 29, the cammed surface 28A thereof will bear against the angular portion 23B of the adjacent fixture 23 whereby holder 17 is forced toward holder 16 as shown by the dash lines of FIG. 2, thereby causing the reflector 11 to bow outwardly as seen in FIG. 2. It will be noted that the curvature of the reflector 11 can be varied to attain the desired lighting intensity and coverage. While the illustrated embodiment discloses a convex bowing of the reflector 111, it will be apparent that concave bowing may also be used, although such concave bowing in a reflector is not usually desired. The bowing of reflector l11 controls its reflective property to the extent that the intensity of the reflected light on any given point can be controlled by the bowing. This eliminates the need for black mesh netting or moving the reflectors further away conventionally used `with prior art devices to control light intensity. The bowing of reflector 11 also causes the reflected light to spread over -a wider area than would the same size reflector if it were planar. Accordingly, a smaller reflector of my design may be employed to light a wider area.
In a modified form of the invention as shown in FIGS. and 6, a link chain `31 may be utilized in lieu of the locking bar 24, above described. In this form of the invention, the construction of the reflector 32 and its holder 33 is similar to that described with reference to FIGS. 1 to 4. However, in this form lof the invention the fixtures 34 and 35 are each formed with a notch 34A, 35A .which opens in the side edge of the respective fixture. Accordingly, a link chain 31 is stretched between fixtures, the chain being held within the notch 34A and 35A of the respective fixtures 34, 35. Thus, it will be noted that the chain 31 can be drawn as tightly as desired to adjust the curvature of the reflector 32.
From the lforegoing description, it will be noted that the reflector 11 or 32 and the holders therefor can be made of relatively light Weight material. The device in either form described can be readily knocked down by first moving either the locking bar 24 or chain 31 from engagement with its respective fixtures. This can be readily attained simply by manually flexing the reflector until the ends of the locking bar =`24 or chain 31 are freed from their respective retaining notches. The frame holders can then be readily slipped off the ends of the reflector. The reflector 11 or 32 can then be rolled or folded ywith a compact roll as shown in FIG. 3A. The completely disassembled device can then be compactly assembled in a small circular carton or carrying case to render it readily transportable by rail, air or motor vehicle and readily storable at minimum space occupancy. To assemble the reflector device, the above steps are reversed. Thus it will be noted that the reflector device can be assembled and disassembled -without the use of any tools, and with a minimum of effort and in a matter of a very short time. The entire device can be inexpensively constructed of light weight material, and can be shipped or stored in a minimum of space. The construction of the reflector 11 is such that it can be readily folded to form a compact roll, yet when Ioperative is provided with an uninterrupted reflecting surface which is quite rigid. Also the degree of curvature of the reflecting surface can be varied in a readily simple manner so as to attain the lighting effects desired. `In the assembled form of the invention it may be readily mounted on any of a number of devices which are presently known and which can hold it steady in any of a number `of attitudes in all but the highest velocity winds. In addition, for placing the assembled device for use, it may `be hooked by the tie bar 24 or chain 31 on various protuberances from walls, tress, shrubs and the like. The reflector assembly 410 may also 'be secured in any desirable fashion to a supporting means which supporting means preferably holds the reflector 11 in a desired fixed position ywhereby to prevent flapping or `the like which will cause variations in lighting that may prove undesirable. While the supporting means and the means for attaching the reflector to the supporting means Iform no part of the present invention, one suitable attaching means for a support is illustrated herein in FIGS. 1 and 2, the attaching means being designated by the reference numeral 40. As shown in yFIGS. l and 2 the attaching means 40 includes a U-shaped bracket 42 which is fixed to the tie bar `13 as by rivets 44 although other securing elements may be employed. Extending through the legs of the U-shaped bracket 42 is a bolt 46 which also extends through an end of a drilled out fitting 4S for holding said fitting in pivotal relation on the bracket 42. The side wall of the fitting '4S is tapped as at 50 to threadedly receive a set screw 52. The drilled out cavity `54 in the fitting 48 is adapted to receive the end of a vertical rod forming part of a stand or support and with the rod so inserted the set screw `52 may be tightened to secure the reflector assembly 11 to the stand or support. The reflector may -be turned about the vertical axis of the stand rod and then held fixed lby the set screw 52. The reflector 11 may be pivoted about a horizontal axis defined by 'bolt 46 which is adapted to frictionally Ihold the reflector in any desired position. As previously noted this is only one manner of securing the reflector assembly `10 to a supporting means. Other suitable means may be employed without departing from this invention.
It will also be recognized that the device is easily maintained as the reflecting surface may be washed with soap or detergent and water or it may be dusted without deleterious effects.
As is true with knocking down the reflector, it will be seen that it can be assembled with great ease and in a matter of a very short time. All that need be done is to flatten out rolled reflector 11, dispose the edges of the reflector in the slots of the two holders, then dispose the tie bar (or chain) as shown and adjust the tension.
While for general use the flaccid sheet is normally metallized with silver colored metal, other colors may be employed to produce desired effects. For example, a gold colored metallized coating may be employed. IIt will be recognized that if different colored reflectors are employed, or if it is desired to use reflectors with different surface treatments, it is not necessary to have a complete reflector device 10 for each reflector 11, the reflectors 11, being interchangeable.
While it has been emphasized herein that the present invention has maximum utility in connection with outof-doors photography and cinematography, the present less fill in light by reliecting window light or artificial light. Accordingly, it is not intended to limit the scope of this invention to out-of-doors reflectors.
While the instant invention has been illustrated and described with reference to particular embodiments'thereof, it will be appreciated that -variations and modilications thereof may be made without departing from the scope or spirit of the invention.
