Two-piece modular yoke

1. A sheet metal yoke for supporting a pair of main runners of a suspended ceiling grid in parallel alignment with a relatively narrow spacing, the yoke having an inverted U-shape with a horizontal span and a depending leg adjacent each end of the span, a lower end of each leg having a tab extending towards the other leg, the tab being arranged to fit in a cross runner slot of a respective one of said pair of main runners and being capable of vertically supporting the one main runner at a desired elevation, each leg having a depending catch comprising an integrally connected vertical element that extends perpendicularly to the leg, a zone between the catch and the leg configured to receive a reinforcing bulb of the main runners, the catch being arranged to restrain a main runner from falling off an associated one of said tabs when said one tab is received in a cross runner slot and when the main runner is vertically oriented, the tab having a vertical fold line established by a weakened zone whereby the tab can be permanently bent towards a web of the main runner to lock the main runner on the yoke.

2. A yoke as set forth in claim 1 , wherein the tab has a hole for receiving a screw for securing the tab against the main runner web.

3. A yoke as set forth in claim 1 , wherein the legs have offset sections that receive a portion of the width of a reinforcing bulb of a cross runner, the offset sections enabling the legs to support a cross runner at a central plane of the cross runner.

4. A yoke as set forth in claim 1 , wherein the span is formed by identical arm sections of L-shaped parts, the identical sections having alignable holes for receiving assembly screws and/or suspension wires.

5. A yoke as set forth in claim 1 , wherein a spacing between the depending legs is adjustable to provide a desired spacing between the pair of main runners being supported by the yoke.

6. A yoke as set forth in claim 5 , wherein the adjustment of the leg spacing is afforded by a series of holes in the span.

7. A sheet metal yoke for supporting a pair of main runners of a suspended ceiling grid in parallel alignment with a relatively narrow spacing, the yoke having an inverted U-shape with a horizontal span and a depending leg adjacent each end of the span, a lower end of each leg having a tab extending towards the other leg, the tab being proportioned to fit in a cross runner slot of a main runner and being capable of vertically supporting the main runner at a desired elevation, comprising two identical L-shaped parts, the L-shaped parts when assembled together each having elements mutually forming said horizontal span, the horizontal span forming elements being formed with mutually indexable fastener receiving holes having predetermined locations corresponding to multiple yoke widths, the L-shaped parts having portions bent out of a plane of the sheet metal, when assembled together the L-shaped parts having their respective bent portions extending in opposite directions with respect to a plane of the yoke.
