(12) The bridging connector 1 illustrated in FIG. 1 comprises a beam connector 2 and a wall engagement element 3. The beam connector 2 is joined to the wall engagement element 3 via a web part 6. The beam connector 2 and the wall engagement element 3 are connected at an angle of 90 degrees as illustrated. The beam connector 2 is a saddle type connector of mainly U-shape. The beam connector 2 comprises a cut-out 20 for receiving a fastener. The wall engagement element 3 is fitted with apertures 30 to receive a fastener for connection to a wall. Fracture assistance weakenings 40, here in the form of V-shaped cut-outs, are arranged at the lower part of the bridging connector to facilitate breaking away of a lower part of the connector, should this be in the way in certain installations. The fracture assistance weakenings 40 makes it possible to break away this lower part by hand, i.e. without using tools. The wall engagement element 3 further comprises a beam engagement portion 4. The beam engagement portion 4 is provided with a first abutment 4a and a second abutment 4b. The beam engagement portion 4 is provided with holes 7 for receiving a fastener. The beam engagement portion 4 is depressed by a distance X in relation to the plane of the wall engagement element 3. The bridging connector is further provided with a wall angle engagement portion 5. The wall angle engagement portion 5 is provided with a first stop element 5a and a second stop element 5b. The first and second stop elements are provided as bent portions of the wall angle engagement portion 5 thereby providing steps in the wall angle engagement portion.

(13) Part of a suspended ceiling system incorporating the bridging connector 1 is shown in FIG. 2a. The beam connector 2 is connected to a bead 27 of a beam 24. Arranged at right angles to this beam 24 is another beam 24. The bead 27 of this beam 24 is arranged in the depressed beam engagement portion 4. A lower edge of the bead 27 is positioned abutting the first abutment 4a of the depressed beam engagement portion 4. A screw 21 introduced through the hole 7 into the bead 27 and thereby firmly connects the beam 24 to the bridging connector 1. The two beams are at the same level in this position, so the lower face of the connected beams are flush.

(14) Similarly, part of a suspended ceiling system incorporating the bridging connector 1 is shown in FIG. 2b, but here the two beams are arranged at different levels off-set by a distance Y, such as 15 mm. The beam connector 2 is connected to a bead 27 of a beam 24. Arranged at right angles to this beam 24 is another beam 24. The bead 27 of this beam 24 is arranged in the depressed beam engagement portion 4. An upper edge of the bead 27 is positioned abutting the second abutment 4b of the depressed beam engagement portion 4. A screw 21 introduced through the hole 7 into the bead 27 and thereby firmly connects the beam 24 to the bridging connector 1.

(15) An enlarged detail of FIG. 2a is seen in FIG. 2c. In this illustration, it is more clearly seen that the beam engagement portion 4 is depressed by a distance X to accommodate the bead 27 of the beam. The distance X is adapted for the width of the bead 27. As an example, a common width of the bead of the beam 24 for suspended ceilings is 6.5 mm, and the distance X of the depression slightly less than half of this, e.g. 2 to 3.2 mm, taking into account the thickness of the material of the beam and potential embossing or stitching of the beam. Often such beams are made of folded sheet metal where the central web portion is double layer.

(16) Part of a suspended ceiling system incorporating the bridging connector 1 is seen in FIG. 3a. The wall engagement element 3 of the bridging connector 1 is connected to a wall via a screw 21. The beam connector 2 is connected to a bead 27 of a beam 24. A wall angle 22 is fixed to the wall via means not shown in the drawing. An upper part of the wall angle is abutting the second stop element 5b of the bridging connector 1. In this configuration there is a well-defined first distance between the top of the wall angle 22 and the top of the beam connector 2. A tile 23 (having so-called E-edge) is arranged to rest on flanges of the wall angle 22 and the beam 24.

(17) Part of a suspended ceiling system incorporating the bridging connector in another configuration is seen in FIG. 3b. The wall engagement element 3 of the bridging connector 1 is connected to a wall (not shown) via a screw 21. The beam connector 2 is connected to the bead 27 of the beam 24. The wall angle 22 fixed to the wall via means not shown in the drawing. An upper part of the wall angle is abutting the first stop element 5a of the bridging connector 1. In this configuration there is a well-defined second distance between the top of the wall angle 22 and the top of the beam connector 2. This means it is possible to fit a ceiling tile 23 with another edge configuration (here illustrated with a tile having the so-called X-edge). The flanges of the beam are arranged in a groove at the edge of the ceiling tile, thereby concealing the beam.

(18) Part of a suspended ceiling system incorporating the bridging connector in another configuration is seen in FIG. 4. Ceiling tiles 23 are often made of materials that are not strong enough to support the weight of lamps or other equipment, so the weight of such equipment must be distributed to the beams of the suspended ceiling grid. For this purpose beams 24 are arranged on top of the tile 23 to hold a lamp 30. The beam 24 holding the lamp 30 is connected to another beam of the suspended ceiling grid at right angles via the bridging connector 1. The top of the beam is abutting the second abutment 4b of the beam engagement element 4, and the beam 24 is fixed to the beam engagement element 4 using a screw. In this position the flange 25 is above the top of the tile 23, so the beam 24 is out of the way of the ceiling tile.

(19) A bridging connector 1′ according to another embodiment is seen in FIG. 5. The beam connector 2 has a slightly different design, but the same function. The wall angle engagement portion also has a slightly different design with a tongue 50 and prongs 53. The tongue 50 and prongs 53 are adapted to engage a wall angle by straddling the top of the wall angle. The tongue 50 comprises indentations 51 functioning as first stop.

(20) FIG. 6 illustrates part of a suspended ceiling system incorporating the bridging connector 1 of FIG. 5. The wall engagement element 3 of the bridging connector 1 is connected to a wall 54 via a screw 21. The beam connector 2 is connected to a beam 24. The wall angle 22 is fixed to the wall via means not shown in the drawing. The wall angle 22 in the illustrated embodiment is stepped to provide a recess near the wall and further is provided with a wall angle flange 29. An upper part of the wall angle is straddled by the tongue 50 and prongs to a second stop element of the bridging connector 1. In this configuration there is a well-defined first distance between the top of the wall angle 22 and the top of the beam connector 2.

(21) FIG. 7 illustrates part of a suspended ceiling system incorporating the bridging connector 1 of FIG. 5 in another configuration. The beam connector 2 is connected to a bead 27 of a beam. The beam has a general inverted T-shape with a web 26 and flanges 25. Another beam is connected to the beam engagement element of the bridging connector using a screw 28.

(22) In the embodiment shown the beam connector is a saddle type connector of mainly U-shape to straddle the top of the beam. Saddle type connectors enables a quick connection between the bridging connector and the beam. The saddle type connector may be configured for snap fit with the top of the beam. Further the saddle type connector may be configured to receiving an end of the beam in sliding engagement. Alternatively, the beam connector may be any suitable type of connector. In the simplest form the beam connector may be a plate portion with holes for screw connection to the beam.
