Abstract

A swinging blade guard assembly for a motor driven saw blade movable from an upper at rest to a lower operational position is disclosed. An upper blade guard is fixed to a pivotally mounted supporting arm that carries the motor driven saw blade and upper blade guard. A lower swinging blade guard is pivotally mounted to the upper blade guard for fully covering the blade in its at rest position and for exposing the saw blade when moved to its operational position. The swinging blade guard assembly includes an elongated link that is pivotally attached at one end to a frame support and includes a pre-configured slot at an opposite end which receives a slidable pin attached to the lower swinging blade guard adjacent its pivotal mounting to the upper blade guard. A bearing element is also attached to the upper blade guard in laterally spaced relationship to the pin for engaging an upper surface of the elongated link. Rotation of the saw blade from an upper at rest to a lower operational position causes the bearing to press against the side of the link while also causing edge surface areas surrounding the pre-configured slot in the link to press against the pin to rotate the swinging blade guard assembly for exposure of the saw blade. A pre-configured shoulder on the upper surface of the elongated link cooperates with the pre-configured slot to control exposure of the lower swinging blade guard relative to the saw blade, by facilitating rapid rotation of the guard during initial downward movement of the saw blade with subsequent slower rotation of the guard during the remainder of the saw blade travel.
