Abstract
A paddle handle latch release device of a spring latch system includes a paddle handle member pivotally mounted in a pan housing, the paddle handle member including an actuating lever which extends below a floor of the pan housing; a spider member rotatably mounted to the underside of the floor, the spider member including latch arms extending from a hub and an operating arm in contact with the actuating lever; and a torsion spring which biases the operating arm against the actuating lever; the spider being rotated from an inactive positioning by the actuating lever when the paddle handle member is manually rotated from a lowered positioning to a lifted positioning, and the torsion spring returning the spider member to an inactive positioning and the paddle handle member back to a lowered positioning when the paddle handle member is released.
