Adjustable hanger for suspended ceilings

A support structure for concealed suspension of a lattice ceiling comprising:

• a first suspension member mounted vertically below an unfinished built ceiling, said first suspension member comprising a wood joist of generally rectangular cross-section and including a lateral face arranged vertically and a bottom face arranged horizontally;
• a second suspension member to support a ceiling panel below said first suspension member;
• and
• support means for joining said suspension members together, said support means comprising a clamp adapted to fixedly connect to said first suspension member, said clamp having an H-shaped plate with a pair of vertical plate portions and a transverse portion, and a pair of resilient flange sections, said support means further including support rod adapted to removably connect to said second suspension member, each said flange section having a first end portion connected to said clamp and a second end portion to connect with the support rod, the second end portions being free to deflect relative to the clamp and towards and away from one another and be biased into gripping engagement against the exterior of the support rod thereby to inhibit vertical movement of said support rod relative to said clamp.

A support for suspending a set of channel sections in horizontal relation below a set of support members fixedly disposed superjacent a built ceiling, said support comprising:

• at least one spring clamp;
• and
• at least one support rod removably connectable to one of said channel sections;
• said at least one spring clamp comprising an H-shaped plate which is fixedly securable at a desired location to one of said support members, a pair of resilient flanges which are cantilevered from said plate and adapted to be arranged in vertically superposed relation when the clamp is secured to said support member, each said flange having a first end only that is fixed to the plate and a second end that is free to flex in opposite directions relative to the plate and normally biased into a first position, and rod engagement means associated with said flanges for engaging and preventing said support rod from vertical movement when the flanges are in said first position and for disengaging and releasing said support rod for movement when the flanges are deflected to a second position.
