Abstract: A novel design of rails for a suspended ceiling, the rails including expansion absorbers. The absorbers are produced so that the rails can absorb an expansion while maintaining the integrity of the ceiling, so that the ceiling panels do not fall in the event of a fire. The rails maintain a significant load-bearing capacity despite the presence of one or more expansion absorbers over the length thereof.

Abstract: A yoke for a ceiling suspension system is disclosed. For example, the yoke may include a yoke body having an upper end configured to be mounted only to another yoke, or to an extension mounted to the other yoke. The yoke body may have a lower end having a first mount configured to be mounted to a first ceiling support member (CSM), and a second mount configured to be mounted to a second CSM that differs from the first CSM. In one version, no portion of the yoke body extends through any portion of the first CSM and the second CSM.

Abstract: A wall support for a ceiling support grid with grid members is disclosed. Each grid member can have a top with a bulb, a web extending downward from the bulb, and a bottom with a flange extending from the web opposite the bulb. Examples of the wall support may include a bracket having a C-shaped channel with a back, a lower flange at a lower end of the back, and an upper flange at an upper end of the back. In addition, the bracket may include only one tab in the lower flange for each grid member. The only one tab may be configured to engage and retain the flange of a respective grid member. The grid member may rest on the lower flange. The lower flange may have no other features for positive engagement with and retention of the flange of the respective grid member.
