DETAILED DESCRIPTION

(17) Referring to the drawings and in particular to FIGS. 1a-d, an exemplary embodiment of a wire trough according to the present disclosure is shown and is generally referred to by reference numeral 10 in different assembled configurations.

(18) Advantageously, trough 10 is configured for fitment into an inside corner 12. Trough 10 allows changing direction of one or more first conduits 14 and one or more second conduits 16 without the need for elbows or bending of the conduits. Thus, trough 10 can, in some embodiments, be sized and configured for use a junction box and/or a splitter box.

(19) In the embodiment of FIGS. 1a and 1b, corner 12 is illustrated as being between two vertical surfaces 18 (e.g., walls). In the embodiment of FIGS. 1c and 1d, corner 12 is illustrated as being between the vertical surface 18 (e.g., wall) and a horizontal surface 20 (e.g., ceiling, floor, etc).

(20) Trough 10 can be secured to surfaces 18, 20 in any desired manner known to those of ordinary skill in the art. Trough 10 can be made of any desired material having sufficient strength and rigidity to cover and/or shield the wires and connections placed therein. In some embodiments, trough 10 is formed carbon steel or galvanized steel. In some embodiments, trough 10 can be painted or powder coated as needed.

(21) Trough 10 is described in more detail with simultaneous reference to FIGS. 2-3.

(22) Trough 10 includes a main body 22, one or more end caps 24, and a cover 26. Main body 22 defines four longitudinally extending walls 28, 30, 32, 34 of the trough having ends 36 and defining an access opening 40 (shown in phantom in FIG. 2) between edges 38 of walls 28, 34.

(23) Cover 26 is secured to trough 10 to selectively close opening 40. In the illustrated embodiment, cover 26 is removably secured to body 22 by a combination of one or more fasteners 42. Here, body 22 includes inwardly bent regions 28-1, 34-1 depending from walls 28, 34, respectively, and cover 26 is secured to these regions.

(24) Of course, it is contemplated for cover 26 to be secured to body 22 and/or caps 24 in any desired manner sufficient to allow selective opening/closing of opening 40. For example, it is contemplated for cover 26 to include a hinge 26′ as shown in FIGS. 4-5.

(25) Caps 24 can be secured to body 22 to close one or both ends 36 in any desired manner. Caps 24 are illustrated as angled or truncated caps, namely having a generally parallelogram shape (i.e., square or rectangular) with one corner angled or truncated as shown in FIG. 2. Also in the illustrated embodiment, caps 24 are removably secured to body 22 by one or more fasteners 44. In some embodiments, caps 24 are formed integrally with body 22. In other embodiments, caps 24 are secured, removably or otherwise, to body 22.

(26) Trough 10 can include one or more knockouts 46 on main body 22, end caps 24, or cover 26. In the illustrated embodiment, knockouts 46 are illustrated on walls 28, 30 of main body 22. Of course, it is also contemplated by the present disclosure for the knockouts to be on walls 30 and/or 32.

(27) It is recognized by the present disclosure that access into opening 40 and the useable volume within trough 10 can be limited by inwardly bent regions 28-1, 34-1 depending from walls 28, 34. Thus, another exemplary embodiment of a trough according to the present disclosure is illustrated with simultaneous reference to FIGS. 6-8 and generally referred to by reference numeral 110. Here, component parts of trough 110 performing similar and/or analogous functions to those of trough 10 are labeled in multiples of one hundred.

(28) For reasons of brevity, only those features necessary for the understanding of the differences of trough 110 are described herein below.

(29) Trough 110 includes a main body 122, one or more end caps 124, and a cover 126. Main body 122 defines four longitudinally extending walls 128, 130, 132, 134 of the trough having ends 136 and defining an access opening 140 between edges 138 of walls 128, 134.

(30) Main body 122 is of simple construction, namely requires only three angled regions which are illustrated as corners 122-1. In some embodiments, corners 122-1 are each ninety degrees so that adjacent walls 128, 130, 132, 134 are perpendicular to one another. Of course, it is contemplated by the present disclosure for corners 122-1 to have any desired angle.

(31) Here, main body 122 lacks the inwardly bent regions 28-1, 34-1 depending from walls 28, 34 of trough 10. Rather, cover 126 includes bent regions 126-1. Cover 126 is secured to trough 110 to selectively close opening 140 by securing at least one of bent regions 126-1 to walls 128, 134 on main body 122.

(32) In this manner, main body 122 provides a larger, unrestricted opening 140. Rather, opening 140 is bounded by the edges 138 of walls 128, 134 and caps 124 without restriction of any connecting features of cover 126 as in trough 10.

(33) Caps 124 can be secured to body 122 to close one or both ends 136 in any desired manner. Caps 24 are illustrated as angled or truncated caps, namely having a generally parallelogram shape (i.e., square or rectangular) with one corner angled or truncated as shown in FIG. 6.

(34) Of course, it is contemplated for cover 126 to be secured to body 122 and/or caps 124 in any desired manner sufficient to allow selective opening/closing of opening 140. For example, it is contemplated for cover 126 to include a hinge 126′ as shown in FIGS. 9-10.

(35) In embodiments where increased volume inside of the trough is desired then possible with cover 126, main body 122 advantageously is also sized and configured for use with covers and end caps of other shapes. Thus, another exemplary embodiment of a trough according to the present disclosure is illustrated with simultaneous reference to FIGS. 11-14 and generally referred to by reference numeral 210. Here, component parts of trough 210 performing similar and/or analogous functions to those of troughs 10, 110 are labeled in multiples of two hundred.

(36) Again and for reasons of brevity, only those features necessary for the understanding of the differences of trough 210 are described herein below.

(37) Trough 210 makes use of main body 122 discussed in detail above. Thus, trough 210 includes main body 122, one or more end caps 224, and a cover 226.

(38) Again, main body 122 defines four longitudinally extending walls 128, 130, 132, 134 of the trough having ends 136 and defining an access opening 140 between edges 138 of walls 128, 134. Main body 122 is of simple construction, namely requires only three angled regions which are illustrated as corners 122-1. In some embodiments, corners 122-1 are each ninety degrees so that adjacent walls 128, 130, 132, 134 are perpendicular to one another. Of course, it is contemplated by the present disclosure for corners 122-1 to have any desired angle.

(39) Caps 224 can be secured to body 122 to close one or both ends 136 in any desired manner. Caps 224 are illustrated as parallelogram caps (i.e., square or rectangular) as shown in FIG. 14

(40) Cover 226 includes a bent region 226-1 defining opposite legs 226-2 of the cover. Cover 226 is secured to trough 210 to selectively close opening 140 by securing at least one of the legs 226-2 to walls 128, 134 on main body 122.

(41) In some embodiments, cover 226 is of simple construction, namely requires only one bent region 226-1. In some embodiments, bent region 226-1 is bent ninety degrees so that legs 226-2 are perpendicular to one another. Here, trough 210 provides a cross-section of generally parallelogram shape (i.e., square, rectangular).

(42) Of course, it is contemplated by the present disclosure for bent region 226-1 to have any desired angle and/or for there to be more than one bent region to provide trough 210 of other cross-sectional shapes. For example, cover 226 can be curved so that the ends of legs 226-2 are perpendicular to one another. Additionally, it is contemplated for cover 226 to include a hinge 226′ as shown in FIGS. 14-15.

(43) In this manner, trough 210 provides the larger, unrestricted opening 140 of main body 122 and provides the additional volume from cover 226.

(44) Moreover, main body 122 provides the ability for the user to modify the trough in the field—by simply using ends 124 and cover 126 (with or without hinge 126′) or using ends 224 and cover 226 (with or without hinge 226′). The modification can be made either during installation—or even after installation in the event of expansion or contraction of the amount of required space within the trough.

(45) It should also be noted that the terms “first”, “second”, “third”, “upper”, “lower”, and the like may be used herein to modify various elements. These modifiers do not imply a spatial, sequential, or hierarchical order to the modified elements unless specifically stated.

(46) While the present disclosure has been described with reference to one or more exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present disclosure. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the disclosure without departing from the scope thereof. Therefore, it is intended that the present disclosure not be limited to the particular embodiment(s) disclosed as the best mode contemplated, but that the disclosure will include all embodiments falling within the scope of the appended claims. wire trough 10 inside corner 12 first conduits 14 second conduits 16 vertical surface 18 horizontal surface 20 main body 22 end cap 24 cover 26 cover hinge 26′ trough walls 28, 30, 32, 34 trough ends 36 wall edges 38 access opening 40 fasteners 42 bent regions 28-1, 34-1 fasteners 44 knockouts 46 wire trough 110 main body 122 end cap 124 cover 126 cover hinge 126′ trough walls 128, 130, 132, 134 trough ends 136 wall edges 138 access opening 140 corners 122-1 bent regions 126-1 wire trough 210 end cap 224 cover 226 cover hinge 226′ bent region 226-1 cover legs 226-2
