2~91~44 Another universal bracket is disclosed in United States patent No. 4,787,587 which includes at least one opening for receiving a fastener on a flat portion thereof. A second flat portion is provided with a notch and a third flat portion forcas an obtuse angle with the second flat portion. Such a bracket would not be suitable for supporting a light fixture on a corrugated surface.
SUMMARY OF THE INVENTION
The mounting bracket according to the invention is adapted to be mounted on a ceiling formed of adjacent U-shaped channels having flaring sides. The bracket has a generally U-shaped cross-section formed by two lateral flat faces and a joining flat face between the lateral faces. The lateral faces are flaring outwardly to angularly correspond to the flaring sides of the channels and to abut thereagainst. The lateral sides of the bracket are provided with holes to receive fastening means for securing the bracket to the channels. The joining face between the two lateral faces is provided with a perforation to allow a ceiling fixture to be hooked therefrom.
In one embodiment, the joining face has a rectangular portion deformed downwardly for forming a V-shaped hook extending croraswise relative to the U-shaped cross-section of the bracket.
In another embodiment, the joining face and one of the lateral faces have a perforated slot extending towards each other to define a common opening through both the lateral face and the joining face. A transverse slot across the perforated slot in 209~.~~4 the lateral face and at a level above the joining face defines a shoulder on each side of the opening. This opening is adapted to allow the sideways passage of a fastening device and of a washer through the transversal slot for allowing the washer to sit behind the shoulder and be retained thereby.

DL~TAILED_D.E.SCRIPTION-OFuTHE--INVENTION
Figure 1 illustrates a bracket according to the invention having a U-shaped cross-section formed 'oy a pair of lateral faces and 12 and a joining face 14. The lateral faces 10 and 12 are flaring outwardly from tile joining face 14 at a predetermined angle to be explained later. The joining face 14 is provided with a perforation obtained by sufficiently deforming the ~~917~~
_LF_ material of the joining face 14 to produce a transversal perforation 16. For this purpose, the joining face 14 is punched downwardly with a triangular punch which is applied over a rectangular surface in joining face 14, the apex of the triangular punch being adapted to break the material of the joining face 14 and produce a generally triangular perforation 16. The apex 20 of the strip 18 will serve to support a suitable hook passing through the perforation 16 as explained later.
The embodiment shown in figure 2, is similarly characterized by two lateral faces 22 and 24 flaring outwardly from a joining face 26 to generally form a U-shaped cross-section. The lateral face 22 is provided with a downward slot 28 continuously extending through a slot 30 in the joining face 26. A
transversal slot 22 is preferably provided through the lateral face 22 at a level adjacent and above the joining face 26 to form a shoulder 34 for a purpose explained later.
The brackets illustrated in figures 1 and 2 are shown in figure 3 fixed under a corrugated ceiling 36. The corrugated ceiling 36 is formed of adjacent U-shaped channels having flaring sides oriented at an angle substantially corresponding to the angl.r_ of the flaring lateral faces of the brackets illustrated in figures 7. and 2.
The bracket illustrated in figure 1 is mounted in a straddling arrangement over channel 38 formed by two flaring sides 40 and 42 at an angle substantially corresponding to the an~le of the f-1ar ng faces 7.0 and 12. The lateral faces 10 and ~0~~7~~
12 are provided with a set of holes 44 adapted to receive screws 46 for securing the lateral faces 10 and 12 on the sides 40 and 42 of the channel 38. When the bracket is fixed to the channel 38, a hook 48 having an open loop 50 can be supported by the strip 18 about its apex 20. The hook 48 is adapted to support a ceiling fixture (not shown). The bracket may also be provided with a pair of openings 52 in the joining face 14. The openings 52 are adapted to allow the passage of electrical wires when the ceiling fixture is an electrical fixture.
The bracket 2i shown in figure 2, is similarly adapted to be mounted on a channel 54 of the corrugated ceiling. By straddling the lateral face 22 and 24 over the sides 56 and 58 of the channel 54 by a set of screws 60 extending through a set of holes 62 provided in the lateral faces 22 and 24 of the bracket 21.
The slots 28 and 30 are adapted to allow the passage of a hook 64 provided with a pair of nuts 66 and 68 and a washer 70. The washer 70 is dimensioned to slide through the slot 32 and be retained inside the bracket 21 by the ciioulder 34 to prevent it from sliding out. The two nuts 66 and 68 are adapted to be tightened against the joining face 26 for maintaining the hook 64 secured along the slot 30. It should be understood that the shoulders 34 and the washer 7U are not compulsory elements when the nuts 66 and 68 are sufficiently large and tightly secured to the bracket 21 for the purpose intended.
The brackets described in figures 1 and 2 may have a length of about 3 to 6 inches and are adapted to support one ceiling fixture. The same bracket may be mounted daft:erently below the 20~1'~44 _6_ corrugated ceiling because such ceilings are generally supported by structural frames of the type shown in figures 4 and 5. The corrugated ceiling 72 is mounted over a structural frame made of truss beams 74 and 76 disposed transversely relative to the channels 78 and 80 of the corrugated ceiling 72. With this arrangement as shown in figures 4 and 5, the bracket 82 according to the in~rention has a length which exceeds the distance between the two beams 74 and 76 021 4Jhlch it is supported. The bracket 82 has a length which usually exceeds 6 feet and is mounted between two adjacent channels 78 and 80 and rests on the upper beams 74a and 76a of the truss beams 74 and 76. The width of the bracket 82 is dimensioned so as to sidewardly abut against the two adjacent channels 78 and 80. Such a dimension allows the bracket 82 to be installed by sliding it over the frame 74 and 76 between two adjacent channels such as 78 and 80.
Considering that brackets such as 82 are relatively long, they are rigidified with lateral flanges 84 to prevent their bending between the two adjacent truss beams 74 and 76. The embodiment of the brackets 82, shown in figure 6, is provided with flanges 84 extending outwardly relat9.ve to the free edges of the lateral faces 86 and 88. Another embodiment for the flanges consists of inwardly projecting flanges 90 relative to the lateral faces 92 and 94.
The bracket 82 shown in figure 6 is provided with perforations 96 of the type shown in figure 2 while the bracket 89 shown in figure 7 is provided w:Lth a perforation 98 of the typo shown i.n ti;urca 1. It should be obvious that tire same 209.744 _, _ bracket may be provided with both types of perforations 96 and 98 along their length.
SUMMARY OF THE INVENTION
The mounting bracket according to the invention is adapted to be mounted on a ceiling formed of adjacent U-shaped channels having flaring sides. The bracket has a generally U-shaped cross-section formed by two lateral flat faces and a joining flat face between the lateral faces. The lateral faces are flaring outwardly to angularly correspond to the flaring sides of the channels and to abut thereagainst. The lateral sides of the bracket are provided with holes to receive fastening means for securing the bracket to the channels. The joining face between the two lateral faces is provided with a perforation to allow a ceiling fixture to be hooked therefrom.
In one embodiment, the joining face has a rectangular portion deformed downwardly for forming a V-shaped hook extending croraswise relative to the U-shaped cross-section of the bracket.
In another embodiment, the joining face and one of the lateral faces have a perforated slot extending towards each other to define a common opening through both the lateral face and the joining face. A transverse slot across the perforated slot in 209~.~~4 the lateral face and at a level above the joining face defines a shoulder on each side of the opening. This opening is adapted to allow the sideways passage of a fastening device and of a washer through the transversal slot for allowing the washer to sit behind the shoulder and be retained thereby.
