ABSTRACT:
An alarm apparatus for shaking a piece of furniture in response to detection of a physical occurrence, such as smoke, fire, CO.sub.2, or even a burglar, is provided. The apparatus includes a detector for detecting the physical occurrence and emitting a signal in response thereto. Connected to the detector is a signalling device that is positioned adjacent the piece of furniture to be shaken in response to the signal emitted from the detector. The signalling device includes a rotating cam shaft with a cam member thereon, against which is positioned one end of a cam follower. The opposite end of the cam follower is directed toward the piece of furniture, so that movement of the follower over the cam as the cam shaft rotates causes the furniture to move up and down.
