An improved manually operated flip dog mountable ceiling speaker enclosure, for ceiling or other panel installation, has a biased sliding ratchet block that can be latched in place by an extension from a T-handle of an integral actuator rod. The ratchet block is controlled in its sliding motion by alignment rods extending from a vertical portion of a base and slidingly received in alignment bores of the ratchet block. A face of the ratchet block has downward pointing ratchet teeth that engage upward pointing ratchet teeth on a barrel of a flip dog to hold the flip dog in a clamped position. Over time, the biasing springs may lose their strength, but the latching of the ratchet block obviates this problem.

Flip out dog leg mountable ceiling speaker enclosure

A manually operated flip dog mountable ceiling speaker enclosure, for ceiling or other panel installation, provides a plurality of flip dogs mounted tangentially on an annular flange around an opening of a speaker can and operated by either pulling on an actuator to create a cam-driven rotation to a radial alignment and a downward dog movement to a ratcheted clamping position, or by first rotating the manual actuator to rotate the dog and then pulling the actuator to pull the dog down into a ratcheted clamping position. Ratchet points on the dog are urged into ratchet points on a wall by a releasable biasing member. Three embodiments are illustrated.
