Device for installation and removal of a ceiling speaker system

A ceiling speaker system, comprising:

• a speaker system having at least one electro-acoustic driver and an enclosure;
• a plurality of threaded rods each having a rod axis, a first end to receive a driver tool and a second end;
• a plurality of brackets each engaging the second end of a respective one of the threaded rods;
• and
• a plurality of spring-loaded tabs each having a clamp surface and a threaded passage in engagement with a respective one of the threaded rods and a spring mechanism, the clamp surface being rotatable relative the respective one of the threaded rods,
• wherein, when the speaker system moves forward through an opening in the ceiling such that the spring-loaded tabs are in contact with a side of the opening, the clamp surfaces are urged toward the threaded rods, and wherein, when the speaker system is further moved forward through the opening such that the spring-loaded tabs are no longer in contact with the side of the opening, the clamp surfaces are displaced away from the threaded rods via their respective spring mechanisms.

A device for securing an object to a ceiling, comprising:

• a threaded rod having a rod axis, a head to receive a driver tool and an end that is opposite to the head;
• a cap nut secured to the end of the threaded rod;
• a bracket engaging the cap nut at the end of the threaded rod;
• and
• a spring-loaded tab having a clamp surface, a threaded passage in engagement with the threaded rod, and a spring mechanism, the clamp surface being rotatable relative to the threaded rod,
• wherein, when the device is attached to the object and the object moves forward through an opening in the ceiling such that the spring-loaded tab is in contact with a side of the opening, the clamp surface is urged toward the threaded rod, wherein, when the object is further moved forward through the opening such that the spring-loaded tab is no longer in contact with the side of the opening, the clamp surface is displaced away from the threaded rod via the spring mechanism, and wherein, when the threaded rod is rotated such that the object moves in reverse down through the opening in the ceiling, the bracket engages the spring-loaded tab to urge the clamp surface toward the threaded rod.
