DESCRIPTION OF_TH_ PREFERRED EMBODIMENTS
Referring to Fig. 1, there is shown an electri-cal raceway floor track 10 which is an elongate aluminum extru~ion which includes a relatively wide lower channel 12, a relatively narrower upper channel 14, and an interconnecting, relatively strong, sound-stopping solid vertical wall 16, connecting the center of the top surface 18 of the lower channel 12 with the center of the bottom surface 20 of upper channel 14.
The lower channel 12 includes upwardly extend-ing flanges 22, 24 along the two respective lateral edges of a horizontal web portlon 26. The upper channel 14 includes upwardly extending flanges 28, 30 along the two respective lateral edges of a horizontal web portion 32.
Short, elongate ridges 39, 35 are formed on the top surface 18 of lower channel web portion 26, on each side of the vertical wall 16, spaced closely therefrom.
Short, elongate ridges 38, 40 are formed on the bottom surface 20 of upper channel web portion 32, on each side of the vertical wall 16, spaced closely therefrom.
Shallow, narrow, elongate grooves 92, 4g are formed in the top surface 18 of lower channel web portion 26, located inwardly about 5/8 inch from the respective flanges 22, 2~. Shallow, narrow, elongate grooves 46, 48 are formed in the top surface 50 of upper channel web portion 32, located respectively slightly outwardly of above ridges 38, 40.
The shallow grooves 46, 48 are provided priMarily to permit the easy and rapid removal of short narrow sections, of upper channel 14, such as short section 51, to form passageways for conduit or cable to be placed through to extend from the electrical raceway below upper channel 14 to a hollow wall cavity above upper channel 1~. The short section 51 i5 removed by cutting two cuts through the 1ange 28 and through the outer edge o web 32 back to groove 46, and bending the section 51 along the weak fold line formed by groove 46 until it breaks.
Referring now to Fig. 2, the floor track 10 is shown attached to a floor 52 by screw 54, 56 which have ~3~
been inserted through lower channel 12, at g~ooves 42, 44 respectively, into floor 52. Groove~ 42, 44 provide a means for properly locating the screws 54, 55 during insertion and for steadying the screws 54, 56 during insertion.
Grooves 42, 44 also provide a line of weakness for removing short sections of flanges 22, 24 at door frames, wall terminations and corners, if necessary, by cutting back to the groove 42 or 44 and bending at the groove 42 or ~4 to break off a short section.
Supported on the top surface 50 of upper channel web portion 32 is a standard sheet metal vertical stud 58 of any suitable cross-sectional configuration, such as a standard C-shaped SCLew stud or an I-stud.
Affixed to stud 58, on each face thereof, is gypsum wallboard 60, 62, preferably affixed by suspension clip assemblies 64 which are piercingly engaged in the back face 66 of wallboard 60 and which are hung on an upwardly opening channel 68 extending through knock-outs 70 in a plurality of parallel vertical studs 58, located at two-foot spacings along partition or wall 72. This preferred method of affixing wallboards to studs is more thoroughly described in U.S. Patent 4,128,979, the disclosure of which is hereby incorporated by reference.
Wallboard 60, 62 can also be affixed to studs S8 by screws or an adhesive, in accordance with the present invention.
In a typical wall constructed in accordance with the invention, -the stud 58 would have a face-to-face dimension of about 2-l/2 inches and would extend from flanqe 28 to flange 30. The bottom edges 74, 76 of 3L3~ 2 wallboard 60, 62 would be disposed against the outer surfaces 78, 80 o~ flanges 28, 30.
Elongate rigid plastic base trim 82, 84 is formed of a wide elongate face portion 86, a short elongate perpendicular flange 88 extending inwardly from the top of face portion 86 and abutting wallboards 60, 62, and a spring-like clip portion 90 near the bottom which with the bottom edge 92 of face portion 86 forms a downwardly opening channel 94 shaped to receive and grasp upwardly extending flanges 22, 24. With the bottom of face portion 86 abutting floor 52 and the short flange 88 at the top of base trim 82, 84 abutting the wallboard, an attractive cover is provided to conceal the floor track 10 .
Above lower channel 12, below upper channel 14 and between wall 16 and each base trim 82, 84, a sizeable elongate hollow path 96, 98 is created, suitable fox locating cables 100, which may be electrical conduit or wire or telephone wire, as may be desired. Located within hollow path 96 is also an electrical outlet box 102, of standard commercial construction, held in place by an outlet box clip 104, and having two electrical outlets protruding through a special outlet section 106 of base trim, as better shown in Fig. 3.
Referring to Fig. 4, the outlet box clip 104 is more clearly shown. Clip 104 is about eight inches long, and includes an eight inch long, one inch high vertical bottom leg 108, a horizontal forwardly extending second leg 110, about l inch by eight inches, a pair of diagonal legs lll, 113, a vertical upwardly extending bifurcated front face 112, a pair of horizontal rearwardly extending ~3~4~:~2 third legs 114, 116 and at the rearward end thereof~
upwardly extending short flanges 118, 120.
~ he clip 104 is locked in place by the bottom leg 108 being disposed behind the lower ridge 34 and the flanges 118, 120 being disposed behind the upper ridge 38. A slight radius 121 in the metal at the junctions of the wall 16 with the upper and lower channels holds the clip 104 against the ridges 34, 38.
The bifurcated portions of face 112 form an opening approximately the shape of electrical outlet box 102 and they include inwardly extending fin~ers 122 located for the screw attachment of box 102 to clip 109.
Fig. 5 shows, in phantom, the method by which clip 104, third legs 114, 116 are bent downward slightly to insert and to remove clip 104 relative to its locked position with flanges 118 and 120 behind upper ridge 38.
Fig. 5 also shows an optional rigid polyvinyl chloride cable support 124 which is an elongate extrusion including an elongate back face 126 and a pair of hori-zontal elongate shelves 128, 130, on which different sets of cables 100 are supported. The back face 126 is flexible enough to be snapped behind the ridges 36, 40 and rigid enough to resist removal when cables 100 are placed on shelves 128, 130.
Fig. 6 shows an optional form of clip 132 which can be used to mount electrical outlet boxes. Clip 132 has a flat vertical back 134 disposed behind ridges 39, 38 with a forwardly extending leg 136 and a sidewardly extending bifurcated lip 138. Used in con-junction with a second similar but opposite clip ~not shown) placed to support the opposite end of an - ~ 3~2~2 electrical outlet box, this combination provides a simplified alternati~e for clip 104.
The preferred embodiment of the present lnven-tion conslsts of a track 10 which is an aluminum extrusion in which the lower channel 12 is about four inches wide, the upper channel is aoout two-and-a-half inches wide, the flanges 22, 24 are about 2/3 inch tall, flanges 28, 30 are about 5/8 inch tall and the overall track 10 is about four inches tall. Ridges 34~ 36, 38) 40 have a height preferably about 0.1 inch. The thickness of most portions of track 10 vary from about .09 to .08 inch while vertical wall 16 is of about .125 inch thickness.
The gypsum wallboard 60, 62 is of about 3/8 to 5t8 inch thickness and the base trim is preferably about four inches in width.
The present invention can also be used with glazing replacing the hollow wallboard partition, partic-ularly in short sections of an overall wall, such as a two foot wide window section each side of a doorway.
Havinq completed a detailed disclosure of the preferred embodiments of my invention so that those skilled in the art may practice the same, I contemplate that variations may be made without departing from the essence of the invention.
