A spring loaded compression strut adapted for mounting between the members of a suspended ceiling grid system and an overhead structural framework. The strut presses downwardly on the grid system so that the latter resists sudden upward movement as might be caused during an earthquake with the corresponding results that the integrity of the ceiling panel system is more adequately protected during such an event since the supporting grid members therefore are not subject to sudden, relative disorientation. The strut includes clip means at its upper and lower ends adapted for respective connection to the overhead structural framework and the grid members which enables the strut to be readily assembled with existing suspended ceiling systems since it is mounted in an external manner with respect to hanger wires found in such existing ceiling systems.
The combination of a suspended ceiling grid system and an overhead structural framework extending thereabove from which said grid system is supportably suspended by a plurality of hanger means, and at least one compression strut extending between said grid system and said overhead framework, said compression strut including freely resilient spring means whereby said strut presses downwardly on said grid system in a resilient manner so that the latter resists upward movement at all times.
The combination with a suspended ceiling grid system and an overhead structural framework extending thereabove from which said grid system is supportably suspended by a plurality of hanger means, of at least one compression strut extending between said grid system and said overhead framework, said compression strut including spring means whereby said strut presses downwardly on said grid system so that the latter resists upward movement, said strut being mounted adjacent to said hanger means and in a substantially parallel manner thereto and including an upper end in connection with said overhead framework, a lower end in connection with said grid system and said spring means being compressably disposed intermediate to and connecting said upper and lower ends one to another, said strut further including a hollow cylindrical body portion telescoped over said spring means and extending in a coaxial manner therewith whereby said strut ends are urged apart one from another by said spring means and clip means on said upper end connecting said strut to said overhead framework and clip means on said lower end connecting said strut to said ceiling grid system with a least one of said clip means extending laterally of said strut and being in connection with said hanger means disposed externally adjacent to said cylindrical body.
The combination with a suspended ceiling grid system and an overhead structural framework extending thereabove from which said grid system is supportably suspended by a plurality of hanger means, of at least one compression strut extending between said grid system and said overhead framework, said compression strut including compression means whereby said strut presses downwardly on said grid system so that the latter resists upward movement, said strut being mounted adjacent to said hanger means and in a substantially parallel manner thereto and including an upper end in connection with said overhead framework, a lower end in connection with said grid system and said compression means being disposed intermediate to and connecting said upper and lower ends one to another, said strut further including a hollow cylindrical body portion telescoped over at least a portion of said compression means and extending in a coaxial manner therewith whereby said strut ends are urged apart one from another by said compression means and means on said upper end extending laterally of said strut and being in connection with said hanger means disposed externally adjacent to said cylindrical body so as to laterally position said strut with respect to said overhead framework and means on said lower end connecting said strut to said ceiling grid system.
