Multi-function key holder

Abstract

The casing of a multi-function key holder has a front casing portion which includes parallel top and bottom parts that extend forwardly and that are spaced apart vertically to define a lens receiving space therebetween, and a rear casing portion which extends rearwardly from the front casing portion and which confines an air chamber. The rear casing portion is formed with an air inlet adapted to permit blowing of air into the air chamber, and an air outlet adapted to permit releasing of the air that was blown into the air chamber, thereby permitting generation of a whistling sound output. A planar magnifying lens piece is disposed in the lens receiving space, and has an edge section mounted pivotally on the front casing portion. The lens piece is movable between a concealed position, where the lens piece is confined between the top and bottom parts of the front casing portion, and an extended position, where the lens piece is exposed from the top and bottom parts of the front casing portion. A key chain has a key holding end adapted for holding a bunch of keys thereon, and a mounting end opposite to the key holding end and mounted on the casing.
