Abstract
A method for using a template to cut an aperture in a planar member at the point where a fixture is to be installed by positioning the template on the planar member and cutting the planar member about the edge of the template.
Description




BACKGROUND OF THE INVENTION




The present invention relates in general to remodeler light fixtures or other devices installed in the walls and/or ceilings of buildings having support structures and methods of installing the support structures. More particularly, it relates to simple and reliable remodeler light fixture support structures and methods of installing same in areas having limited, if any, access from above or behind the light fixture. Even more particularly, it relates to light fixture support structures that may be attached without tools and which meet Underwriters Laboratory (UL) standards and building codes. Most particularly, it relates to a template having an adhesive means for properly positioning and sizing an aperture in a planar member and methods of properly positioning and forming an aperture in planar members using the template.




Various methods, systems and apparatuses for installing lighting fixtures or other devices in existing construction, as opposed to new construction, have been developed and practiced by the construction industry. Examples of prior systems and apparatuses for installing lighting fixtures in existing construction in the field of the present invention include those described in patents of the assignee of the present application: U.S. Pat. No. 5,031,084; 5,317,493; 5,222,800; 5,374,812; 5,452,816 and 4,646,212. Additionally, U.S. Pat. No. 2,454,119 is related to the subject matter of the present application. These patents are representative of patents directed to the subject matter of the present application.




The prior art constructions and methods all have disadvantages in that, they have a plurality of parts requiring assembly to the structure often requiring the installer to use tools, including simple hand tools, during installation. Further, with the prior art constructions, installers are unable to separate the mechanical portion from the electrical portion of the installation, often requiring a qualified electrician to perform the entire installation rather than allowing a lesser skilled worker to install the mechanical portion and an electrician to install the electrical portion at a later time. These prior remodelers often comprised multiple unattached components and, thus, there is the possibility that unattached structural components might become separated from the fixture during the installation. When the unattached structural components fall during installation in a ceiling, the installer has to go down the ladder to retrieve the fallen components. Thus, the prior remodelers are more complicated than just a simple unitary part that the installer can hold in one hand while climbing a ladder.




These prior remodeler fixtures and methods are somewhat inadequate when used in “rough-in” sections which allow contractors to do the mechanical and the electrical work required to finish the installation of a new light fixture in an existing construction. In the installation method typically used in remodeling applications, the trim installation, or the installation of the light fixture itself, is usually accomplished after painting and other mechanical alterations are made in the space. The trim merely finishes the installation of the light fixture.




Another problem with the prior remodelers relates to accurately positioning, sizing and forming the aperture in the planar member for receiving the specific remodeler light fixture support structure. Prior methods and devices for accurately positioning, sizing and forming the aperture for receiving the remodeler lighting fixture support structure included specialized hole cutting tools utilized by high volume installers for each of the 1,100 size, 1,000 size and 2,000 size remodeler light fixture support structures. These hole cutting tools are expensive and were subject to breakdown. Other methods of locating and sizing the aperture included tracing the outer edges of a cardboard template on the planar member and then using a saw to cut along the traced edges. The cardboard template tracing method was used by individuals or tower volume installers unable or unwilling to pay the high price for the specialized hole cutting tools.




SUMMARY OF THE INVENTION




It is an object of the present invention to provide improved means and methods for positioning and properly sizing an aperture in planar members.




Another object of the present invention is to provide improved methods, systems and apparatuses for accurately locating and sizing an aperture in a planar surface.




Still another object of the present invention is to provide a template having an adhesive means on one side for accurately positioning an aperture in a planar member.




A further object of the present invention is to provide a template for marking the position on the surface of a planar member where an aperture is to be cut by adhering to the planar member.




A still further object of the present invention is to provide a template once adhered to a planar member for guiding an installer in forming an aperture in the planar member.




In accordance with the present invention, one representative article of manufacture for locating and sizing an aperture to be formed in a planar member, the article comprising: a template having written indicia on one side and an adhesive means on the other side; and a backing member, operatively positioned in contact with the adhesive means, for maintaining the effectiveness of the adhesive means until removal of the backing member from contact with the adhesive means.




In accordance with the present invention, a representative template comprises a thin means having written indicia operatively positioned on one side and an adhesive means operatively positioned on the other side.




In accordance with the present invention, one representative method for forming an aperture in a planar member having an inner and an outer surface, the method comprising the steps of: providing a template including a center aperture, written indicia on one side and an adhesive material on the other side and a backing member; separating the template having the adhesive applied thereto from the backing; positioning a mark placed on the planar member for indicating the center of the position where the aperture is to be cut; positioning the template with the adhesive portion facing the planar member such that the mark shows through the center aperture of the template; and cutting the planar member about the edge of the template.




In accordance with the present invention, one representative method for installing a fixture in a planar member comprising the steps of: determining the location where an aperture is desired to be formed in the planar member; positioning a template having written indicia on one side and an adhesive means on the other side at the location where an aperture is desired to be cut in the planar member; forming an aperture at the point where the fixture is to be installed by cutting around the edge of the template; positioning a fixture support structure having a perimeter and a lip having an inner and an outer surface in the formed aperture; operatively positioning at least two means about the perimeter of the fixture support structure for retaining the fixture support structure in position in the aperture formed in the planar member; positioning the fixture support structure in the aperture; positioning the at least two retaining means contiguous with the inner surface of the planar member; and manipulating the at least two retaining means such that the fixture support structure is maintained in position in the aperture by clamping the planar member between the lip portion of the perimeter member and the retaining means.




Other objectives and advantages of the present application will become apparent from the following description, the accompanying drawings and the appended claims.

DETAILED DESCRIPTION OF THE INVENTION




In carrying out the present invention in preferred forms thereof, we have provided improved methods, systems and apparatuses for installing a fixture, such as, for example, a light fixture in existing construction in a manner that significantly reduces installation time and facilitates flexible contractor scheduling in that the. mechanical and the electrical portions of the installation can be readily accomplished at different times by different personnel. The methods, systems and apparatuses of the present invention are simple, versatile, flexible, low maintenance, cost effective, require no specialized tools and are space efficient. The methods, systems and apparatus of the present invention include unique combinations of elements and steps that facilitate the installation of a remodeler light fixture by using an adhesive template for positioning and sizing an aperture for receiving a support structure having clamp means operatively connected thereto.





FIGS. 1-18

illustrate a representative new remodeler light fixture support structure and new methods of installing the remodeler light fixture in the support structure. As shown in

FIGS. 1-8

, the remodeler light fixture support structure


20


includes a perimeter member


22


having at least two, and preferably three, slots


24


,


26


,


28


operatively formed therein. The perimeter member can be circular or of any other geometric shape which corresponds to the shape of a desired light fixture. Specifically, the perimeter member can be shaped as desired, such as, for example, square, rectangular, elliptical, pentagonal, etc.




As shown in

FIGS. 1-5

, the perimeter member comprises a wall portion


30


and a lip portion


32


(the lip portion may be continuous or segmented) formed to protrude outwardly from the wall portion


30


and, as illustrated, the perimeter member is circular and has the preferred three slots


24


,


26


,


28


formed therein spaced about one hundred twenty (120°) degrees apart. These slots


24


,


26


,


28


are for receiving a light fixture support structure retaining means or a mounting strap


40


. The details of the mounting strap


40


will be described below.




As shown in

FIG. 1

, three representative trim springs


42


,


44


,


46


(three trim springs are presently preferred for the 1000 and 2000 series remodelers and four trim springs presently preferred for the 1100 series remodeler) are operatively positioned about one hundred twenty (120°) degrees apart around the interior periphery


48


of the perimeter member


22


for centering the trim or the lighting fixture once the trim


50


(see

FIG. 18

) is installed into the perimeter member


22


. It should be understood that more trim springs or other supporting means could be used, such as, for example, four (4) trim springs positioned about ninety (90°) degrees apart (1100 series remodeler). In fact, any number of trim springs or other supporting means could be used as long as they support the trim


50


in accordance with known conventional standards. The trim springs


42


,


44


,


46


are positioned on the inner periphery


48


of the perimeter member


22


such that the position of the trim springs


42


,


44


,


46


with respect to the trim


50


is constant regardless of the planar member


52


thickness. In other words, the distance from the lip portion


32


of the perimeter member


30


to the trim springs


42


,


44


,


46


is constant. If this distance were not constant, planner thickness would determine trim spring location. In that case, the thicker the planer material the farther away the trim springs would be located relative to the trim. If all trims were uniform along the side or vertical walls, this would not be a problem but the side walls of most trims are not uniform and actually curve inwardly thereby reducing the distance between the side walls.




As shown in

FIGS. 3 and 4

, because the mounting straps


40


interact with the perimeter member


22


in a specific manner, the slots


24


,


26


,


28


are formed in perimeter member


22


at the junction between the wall portion


30


of the perimeter member


22


and the lip portion


32


. The wall portion


30


is, presently preferably, about 0.75 inch high and has a tip


31


at one end which is, presently preferably, bent at about a fifteen (15°) degree angle toward the interior portion of the perimeter member


22


. The lip portion


32


is formed to protrude outwardly from the wall portion


30


. The lip portion


32


extends outwardly from the wall portion


30


at about a ninety degree (90°) angle therewith. The slots


24


,


26


,


28


for receiving the mounting straps


40


are positioned in the curved portion of the perimeter member


22


between the lip portion


32


and the wall portion


30


with the dimensions of the lip portion from the interior surface of the perimeter member


22


toward the end of the lip portion most remote from the wall portion


30


being about, presently preferred, 0.10 inch and the dimensions of the portion of the slot


24


from the surface of the lip portion


32


most remote from the angled tip


31


of the perimeter member


22


being about 0.15 inch toward the angled tip


31


. The width of the slots


24


,


26


,


28


is, presently preferred, about 0.41 inch.




As shown in

FIG. 5

, one additional slot


54


and related aperture


60


for operatively positioning the trim springs


42


,


44


,


46


(see

FIG. 1

) are formed in the perimeter member


22


with the circular aperture being located about 0.281 inch from the lower surface of the lip portion


32


. The about 0.093 inch by about 0.510 inch slot


54


is positioned about 0.220 inch above the center radius of the 0.136 radius aperture


60


toward the angled tip


31


, of the wall portion


30


of the perimeter member


22


.




It should be understood that all part dimensions are for illustrative purposes and that those skilled in the art could easily determine appropriate dimensions for a plurality of possible support structures to meet a plurality of different application requirements.




As illustrated in

FIGS. 2 and 3

, the perimeter member


22


, is conventionally formed from about 0.032 inch thick C-1011 or C-1008 hot dipped galvanized G-60 minimum spangle, matte finish commercial quality metal. The perimeter member


22


can be either formed as a continuous member or formed by rolling such that there is an overlap connecting portion


36


. The overlap


36


between ends of the perimeter member


22


, is presently preferred, a minimum of about one (1) inch. The overlapping portion


36


is operatively connected in a conventional way such as, for example, by interlocking one overlapping thickness of the material into the other by a patented process known as “TOG-L-LOK.” Alternative connecting methods include, but are not limited to, welding, riveting, using a tab and slot connection, adhesive, nuts and blots, screws, etc. When using three mounting straps


40


and four trim springs, the minimum angle between a mounting strap slot and a slot for the trim spring is presently preferably about thirty (30°) degrees.




As shown in

FIGS. 2 and 16

, a single slot


70


, relatively smaller than the mounting strap slots


24


,


26


,


28


, is also operatively formed in the perimeter member


22


. This smaller slot


70


facilitates the accurate assembly of the support structure


20


at the factory and is used for securing a junction box


72


(as will be described later) in position proximal an opening or aperture


74


in a planar member


52


. The position of the junction box


72


relative to the aperture


74


must be accurate so that a thermal probe


76


, for detecting properly placed installation (not shown), is automatically and repeatedly installed at the required height off the ceiling or planar member


52


. The junction box


72


must be accurately and securely positioned on the surface


78


of the planar member


52


relative to the trim


50


positioned in the aperture


74


such that the junction box


72


is prevented from overhearing. In other words, the junction box


72


must be reliably installed at a constant, predictable distance from the edge


80


of the aperture


74


in order to prevent junction


72


malfunctions. Thus, it is important to repeatedly, consistently and predictably position the junction box


72


so that when tested, all requirements for Underwriters Laboratories (UL) and building codes are met.




An important component of the junction box


72


is a base plate


84


having a lip


86


for positioning the junction box


72


relative to the aperture


74


in the planar member


52


regardless of the size of the standard light fixture aperture


74


that is cut. The length of the base plate


84


should be sufficiently long to properly position the thermal probe


76


relative to the installed trim


50


. A socket


88


is conventionally operatively connected to the junction box


72


.




In an effort to assist the installer of the remodeler lighting fixture, the installation system includes a template


90


having the three standard sizes (1,100, 1,000, and 2,000) for remodeler lighting fixtures depicted thereon. Specifically, as illustrated in

FIG. 11

, one representative template


90


includes indications


200


,


202


,


204


for where the lighting fixture installer should cut the planar surface to install the remodeler lighting fixture. Size 2,000, 1,000 and 1,100 lighting fixtures having a radius of 1⅞ inches,


206


, 2{fraction (9/16)} inches,


208


and 3⅜ inches,


210


respectively are depicted on the template


90


. The template


90


includes detailed instructions for the installer concerning the size aperture


74


or hole to cut in the planar member


52


for each specific size lighting fixture.




The template


90


, presently preferably, comprises a circular relatively thin piece of paper


212


or other material capable of performing the functions of the template


90


and of having printed indicia permanently or semi permanently placed thereon. The template


90


includes an adhesive means (not shown) on the side opposite the printed indicia. Any adhesive means that is operative to maintain the template


90


in place on the planar member


52


until the aperture


74


has been formed is acceptable. An acrylic pressure sensitive adhesive commercially available from Fasson Corporation is the presently preferred adhesive means used with the representative template. The template


90


has a protective backing


214


supplied with the template


90


covering the side of the template having the adhesive means. The protective backing


214


enables the adhesive on the backside of the template


90


to retain its adhesive properties until the template


90


is ready to be applied to a surface of a planar member


52


.




To assist in the proper location of a template


90


and subsequently the proper and accurate location of the aperture


74


that is cut in the planar member


52


utilizing the template


90


, a hole


216


, presently preferably about 0.20×about 0.20 inch square, is formed in the center of the template


90


. This hole


216


is typically utilized to guide the installer to position the template


90


where the template is to be adhered to the planar member


52


so that the aperture


74


will be accurately cut in the planar member


52


.




At a radius of about 2{fraction (9/16)} inches from the center of the hole


216


formed in the center of the template


90


, a first set of perforations or slits


220


are positioned in the template


90


but not through the backing


214


. These perforations


220


are provided along with material webs for maintaining the integrity of the template


90


. The material webs are positioned, presently preferably at four positions, about ninety (90°) degrees apart, as shown by the arrowheads


222


,


224


,


226


,


228


in FIG.


11


. Further, at least one additional set of perforations


230


with similar material webs located at the arrowheads


232


,


234


,


236


,


238


are formed in the template


90


at about a radius of 1⅞ inches from the center hole


216


.




The perforations


220


,


230


divide the template


90


into three portions. The outer edge


240


of the template


90


to the first set of perforations


220


constitutes an outer portion


242


. A middle portion


244


is formed by the area between the first set of perforations


220


formed at a radius of about 2{fraction (9/16)} inches from the center and the set of perforations


230


formed at a radius of about the 1⅞ inches from the center


216


of the template


90


. The inner portion


246


is the portion from the hole


216


in the center of the relatively thin paper template to the second set of perforations


230


. The significance of the perforations


220


,


230


and the three portions


242


,


246


,


248


will be described in detail later.




It should be understood that the location of the perforations on the template are illustrative only and that other locations for the sets of perforations in the template


90


could be used for applications other than the specific remodeler light fixture described. Further, the template


90


and the perforations shown could be formed in shapes other than circular, including but not limited to, square, rectangular, elliptical or other geometric shapes corresponding to the shape of an aperture to be formed in a planar member.




As specifically shown in

FIGS. 6-8

, the mounting strap


40


, as used in the support structure


20


and methods of the present invention, is, presently preferably, a thin, long flat member


94


having a hook portion


116


at one end and a v shaped two leg member


96


, with each of the legs


106


,


108


having a flange


102


,


104


for engaging the surface


78


of the planar member


52


at the other end. The portion between the two legs


106


,


108


and the hook end


116


is, presently preferably, about three (3.0) inches long, about 0.018 inch thick and about 0.37 inch wide. In any event, the length of the flat member


94


should be sufficient to cover any thickness of planar member


52


or ceiling likely to be encountered.




AS illustrated in

FIG. 7

, the two legs


106


,


108


are positioned at about, presently preferably, sixty (60°) degrees with respect to each other. Connected to each leg


106


,


108


presently preferably, at about a ninety five (95°) degree angle therewith are the flanges


102


,


104


, which are about 0.14 inch wide and about 0.625 inch long. These flanges


102


,


104


are the part of the mounting strap


40


which contact the inner surface


78


(see

FIG. 14

) of the planar member


52


and distribute the weight of the remodeler light fixture such that the structural integrity of the material of the planar member


52


is not penetrated or broken down by the weight of the fixture. In short, the flanges


102


,


104


distribute the weight of the light fixture over a larger surface area of the planar member


52


than those of the prior art thereby avoiding complete reliance on the structural integrity of the planar material, such as, for example, how thick or how thin the planar member


52


is at any given point, for bearing the full weight of the light fixture at only a few sharp points of contact. The ninety five (95°) degree angle between the legs and the flanges provide a tighter, more secure installation.




Additionally, these flanges


102


,


104


are the components which either dig into the planar member


52


or raise off the planar member


52


during attempted rotation of the support structure


20


when an installer or whatever attempts to rotate the support structure


20


, as will be described below. It should be understood that dimensions of the flanges


102


,


104


can vary and that the flanges illustrated were developed to meet a specific physical test of installation.




The angle of the connection between each leg


106


,


108


and the long flat member


94


should be greater than about ninety (90°) degrees because of the potential that the mounting strap will slide away from the planar material when the mounting strap is pulled down into contact with the planar member


52


. The angle of the connection between each leg


106


,


108


and the respective flange


102


,


104


should preferably be about ninety (90°) degrees but less than about one hundred seventy (170°) degrees because the closer the angle between the leg and the flange is to one hundred eighty (180°) degrees, the smaller the surface area of the flange contacting the planar member


52


for distributing the weight of the fixture.




The hook portion


116


of the mounting strap


40


is designed for holding the mounting straps


40


in a specific position in the perimeter member


22


after leaving the factory and before the support structure


20


is installed in an aperture


74


in a planar member


52


. As illustrated in

FIGS. 1 and 13

, when the mounting straps


40


are initially located in the slots


24


,


26


,


28


of the perimeter member


22


, the inner surface


120


of the hook portion


116


is in contact with the inner surface


122


of the perimeter member


22


and the inner surface


124


of the mounting strap flat member


94


is contiguous with the outer surface


128


of the perimeter member


22


with the connecting portion


130


of the hook


116


being pulled contiguous with the portion of the mounting strap slots


24


,


26


,


28


placed therebetween. After assembling in this manner, the mounting straps


40


can be bent into position and nested in the center of the perimeter member


22


. In this nested position, a plurality of light fixture support structures


20


can be efficiently packaged for shipment and distribution to end users.




One important element of the present invention is the light fixture support structure retaining means or mounting strap


40


which, when properly positioned in the, at least two and preferably three, slots


24


,


26


,


28


formed in the perimeter member


22


of the support structure


20


, provides for the distribution of the weight of the installed lighting fixture such that the structural integrity of the planar member


52


is maintained. The mounting straps


40


include means for distributing the weight of the support structure


20


over a larger surface area of the surface


78


of the planar member


52


than those of the prior art and, thus, allows the lighting fixture to be installed in planar members having less than optimal structural integrity such as, for example, ceiling tile.




As shown in

FIG. 8

, in addition to distributing the weight of the lighting fixture or trim


50


over the surface


78


of the planar member


52


, the mounting strap


40


of the present invention is designed to prevent the support structure


20


from rotating in the planar member


52


. Specifically, it is undesirable to have the support structure


20


rotate in the aperture


74


in the planar member


52


when installing the trim or when installing incandescent light bulbs, etc. Therefore, the surface


100


of the mounting strap flange


102

As shown in

FIGS. 9

,

,


15


-


17


and


19


, a unique junction box


72


and the associated socket


88


, useful with the systems apparatus and methods of the present invention includes a base plate


84


having a tab or tongue


92


operatively connected thereto. The base plate


84


has the tab or tongue


92


at one end


130


and the unique junction box


72


including the thermal probe


76


at the other end


110


. The tab


92


is connected at the end


130


of the base plate


84


most remote from the junction box


72


. At the end


130


most remote from the junction box


72


, the base plate


84


has an arched portion


132


with, presently preferred, two feet


140


,


142


, formed at the end thereof. The feet


140


,


142


are formed respectively at each end of the arched portion


132


and at about a ninety degree (90°) angle with the plane of the base plate


84


. The feet


140


,


142


are for interacting with the aperture


74


formed in the planar member


52


and cooperating with the base plate


84


and the tab


92


to insure that the junction box


72


when connected to the support structure


20


perimeter member


22


and with the feet in the aperture


74


, is accurately positioned relative the aperture


74


such that all applicable regulations and codes are met (see FIGS.


16


-


18


). The feet


140


,


142


and the tab


92


combine to prevent the base plate


84


from changing locations/positions on the surface


78


of the planar member


52


(ceiling) once installed, therefore insuring that the junction box


72


remains in the installed position.




The new unique eight sided (including an access door or cover


146


when closed) junction box


72


is specially constructed with minimal gage material. The junction box has a specifically designed access door


146


and a grounding wire


150


(see

FIG. 19

) which is uniquely attached to the box


72


. An integral electrical cable clamp


152


operatively positioned inside the junction box requires no tools for electrical cable attachment thereto while being able to pass requisite testing. Specifically, the internal volume of the junction box is about twenty-one (21) cubic inches. This internal volume is believed to be the optimum size for accommodating the number of electrical wires allowed to be inside a junction box of this type by code and regulation. The construction of the unique junction box includes optimization of the location of the thermal probe


76


and the incoming electrical wire and the strategic orientation of the flexible conduct to minimize the junction box's dimension so that the entire junction box can be installed into a 3¾ inch diameter aperture. The complete junction box assembly is accomplished without hardware, such as, for example, screws, rivets or other hardware. Specifically, as shown in

FIG. 19

, a plurality of tabs


154


and a plurality of slots


156


slots (tab and slot construction) are utilized along with a snap and lock hinged door


146


. The junction box


72


provides optimal wiring and volume and is capable of being passed through a 3¾ inch diameter opening in a building surface or planar member


52


.




As shown, the junction box of the present application is constructed of a minimal gauge material. In particular, the eight sided junction box of the present application is configured such that the interior space is optimized for both interior volume and for installation through an aperture in a planar member


52


approximately 3¾ inches in diameter, as mentioned above. The door


146


to the junction box is hinged at


158


and is captive. The door when opened swings open and, is captive, such that gravity holds it open without fasteners for easy access when connecting wiring within the junction box.




Another feature of the junction box concerns the connection of the ground wire


150


to the junction box during the junction box assembly process by placing the ground wire between a tab


154


of the eight sided wall member and between a slot


156


in the junction box plate


84


so that the ground wire


150


is securely connected to the junction box


72


(see FIG.


19


). Access for non metallic sheathed cable (Romex) is through the hinged door versus a knockout detail of the prior junction boxes. During the connection of the cable, the hinged knockout


160


remains intact versus the knockout slug of the prior junction boxes and does not require any tools in order to open whereas the prior art required tools to pry open the knockout.




Finally, the cable clamp


152


hinged to the wall of the junction box in combination with the access hole


160


size in the wall of the junction box provides for fast and easy insertion of the sheathed cable and automatically adjusts for 12-14 gauge NM sheathed cable. Further, the cable clamp


152


enables the junction box to resist UL's 50 lb. pull test in one motion without having to use tools or having to perform a secondary action to clamp or fasten the sheathed cable. Specifically, the cable clamp is structured such that once the cable is inserted through a slot


162


in the clamp


152


and an attempt is made to pull the cable back out of the junction box, the cable clamp


152


pivots about the hinge thereby compressing the cable between the opposing sides of the slot


162


in the clamp


152


(strain relief feature).




When connecting wire(s) to the junction box, with the 1100 and 1000 series remodelers, the junction box can be hung temporarily from the perimeter member to assist with the wire connections. When connecting wire(s) to the junction box, an open hinged knockout


160


is opened and a wire, preferably non-metallic sheathed cable, is pushed through the knockout opening


160


and through the cable clamp


152


.





FIGS. 12-18

illustrate one method for installing a light fixture in existing construction using the illustrated circular light fixture support structure


20


. First, an aperture


74


is cut in the planar member


52


at the desired location utilizing the template


90


, as described above. Once the aperture


74


in the planar member


52


has been completed, the assembled support structure


20


, including the preferred three mounting straps


40


and the trim springs


42


,


44


,


46


, is inserted into the aperture


74


. The light fixture installer holds the support structure


20


in position in the aperture


74


, reaches in and pushes down on the mounting straps


40


(FIG.


13


), preferably, one at a time until each mounting strap


40


contacts the inner surface


78


of the planar member


52


such that the planar member


52


is sandwiched between the mounting straps


40


and the inner surface


34


of the lip portion


32


of the perimeter member


22


. As shown in

FIG. 14

, once each mounting strap


40


is in contact with the inner surface


78


of the planar member


52


, the light fixture installer bends the mounting straps


40


and secures the support structure


20


in position in the aperture


74


effectively clamping the planar member


52


between the lip portion


32


of the perimeter member


22


and the retaining means or mounting strap


40


.




At this point, it should be understood that, due to the flexibility of the system and methods of the present invention, it is possible to install the support structure


20


either before or after the wiring has been installed. Specifically, as shown in

FIG. 15

, conventional electrical wire


144


to be connected to the junction box


72


. This particular connection, as mentioned above, could be accomplished by an electrician before the light fixtures support structure


20


is placed in the aperture


74


in the planar member


52


or it could be accomplished after the light fixtures support structure


20


is placed in the aperture, as will now be discussed.




Once the junction box


72


and the connected socket


88


are connected to the electrical wiring


144


and the support structure


20


has been installed in the aperture


74


, the junction box tab or tongue


92


is inserted through the most narrow slot


70


in the perimeter member


22


marked, “J-Box”, between the planar member


52


and the perimeter member


22


and pulled into position such that the interior surface of each foot


140


,


142


of the junction box base plate


84


is properly inserted into the aperture


74


contiguous with the cut edge of the planar member


52


, as shown in

FIGS. 16 and 17

. Once the junction box


72


is properly positioned, the junction box tab


92


is inserted through the narrow slot


70


and pulled down until the junction box plate


84


sits flat on the interior surface of the planar member


52


. Then, the tab


92


is bent upward securing the junction box


72


into proper position, as shown in FIG.


17


.




As shown in

FIG. 18

, after the junction box


72


has been secured to the support structure


20


, thereby automatically repeatedly, consistently and predictably positioning the junction box


72


to meet Underwriters Laboratory and code requirements, the socket


88


is attached thereto, as is known in the art, and the trim


50


or the light fixture is then positioned inside the support structure


20


.




As mentioned in the background of the invention, no known previous remodeler light fixture support structures had the capability of ready installation into variable thickness planar members and had the capability of being installed in planar members having less than ideal structural integrity or structural capability.




When using, such as, for example, the representative template


90


illustrated in

FIGS. 11-11B

, an installer merely separates the template


90


having the adhesive applied on one side thereof from the backing


214


. Once separated, the installer locates a mark (not shown) placed on the planar member


52


to indicate the center of the position where it is desired to install a fixture, such as, for example, the remodeler light fixture support structure


20


or other devices, and then positions the side having the adhesive on the planar member


52


with the mark showing through the center hole


216


of the template


90


. If the remodeler light fixture support structure


20


to be installed is a size 1,100 fixture, the installer merely cuts about the outer edge


240


of the template


90


, as shown. Once completed and the portion of the planar member


52


that has been severed from the planar member


52


is removed forming an aperture, the installation of the fixture support structure is then completed.




If the remodeler light fixture support structure is a size 1,000 fixture, before the proper positioning of the template


90


on the planar member


52


, with the template


90


still positioned on the backing


214


, the installer separates the inner


246


and middle


244


portions of the template from the backing


214


(See

FIG. 11A

) leaving the outer portion


242


of the template


90


adhered to the backing. This is accomplished by breaking the webs of material at the first set of perforations


220


and peeling the inner portion


246


and the middle portion


244


of the template


90


from the backing


214


and leaving the outer portion


242


on the backing


214


. Next, the inner portion


246


and the middle portion


244


of the template


90


are positioned on the planar surface where the fixture is to be installed. As before, the installer uses a saw or other means to cut the planar member


52


around the outer edge of the middle portion


244


at a radius of about 2{fraction (9/16)} inches. Once completed, the severed portion of the planar member


52


is removed thereby forming the aperture


74


in the planar member


52


as above.




If the remodeler light fixture support structure to be installed is a 2,000 size fixture having about a 1⅞ inch radius, with the template


90


still positioned on the backing


214


, the installer separates the inner


246


portion of the template from the backing


214


(See

FIG. 11B

) leaving the outer portion


242


and middle portion


244


of the template


90


adhered to the backing. This is accomplished by breaking the webs of material at the second set of perforations


230


and peeling the inner portion


246


of the template


90


from the backing


214


and leaving the outer portion


242


and the middle portion


244


on the backing


214


. Next, the inner portion


246


of the template


90


is positioned on the planar surface where the fixture is to be installed. Then, as above, once the inner portion


246


has been properly positioned on the planar member


52


, the installer merely cuts the planar member


52


using the outer edge of the inner portion


246


to guide a cutting means such that the cut portion of the planar member is severed from the planar member


52


.




Once again, it should be understood that the method of using the template is not limited to the described lighting application and that the template described could be used in any application requiring that an aperture of any geometric shape be formed in a planar member. Further, it should be understood that the present invention is not intended to be limited to the representative three portion template shown in the drawings and described above in that the present invention requires only a template having written indicia on one side and an adhesive on the other side. Preferably, the template is adhesively held on a backing member. Finally, it should be understood that the methods described above are not restricted to an installer cutting the planar member using the outer edge of the appropriate portion of the template to guide a cutting means such that the cut portion of the planar member is severed from the planar member and that the inner edge of an appropriate portion could also be used, as would be obvious to those skilled in the art.




Thus, it can be seen that all objectives of the present invention have been met. Specifically, the present invention provides: improved means and methods for positioning and properly sizing an aperture in planar members; improved methods, systems and apparatuses for accurately locating and sizing an aperture in a planar surface; a template having an adhesive means on one side for accurately positioning an aperture in a planar member; a template for marking the position on the surface of a planar member where an aperture is to be cut by adhering to the planar member and a template once adhered to a planar member for guiding an installer in forming an aperture in the planar member.




Changes and modifications in the specifically described embodiments can be carried out without departing from the scope of the invention which is intended to be limited only by the scope of the appended claims.
