ABSTRACT:
A hinge device for a casing of the type having a body portion and an upper cover the device including a substantially L-shaped mounting plate adapted to be securely mounted to the body portion of the casing, two washers respectively attached to both sides of the mounting plate, a pivotal axle having a mounting portion adapted to be securely mounted to the upper cover of the casing, an extension pivotally received in a hole of the mounting plate, a spring member, and a nut mounted on a threaded end portion of the extension. The nut biases the spring and allows the pivotal axle to be freely pivotable relative to the spring. When a desired position of the upper cover relative to the body portion of the casing is reached, the spring member biased by the nut exerts a longitudinal force on the pivotal axle to retain the pivotal axle in position.
