Abstract

A hinge device for use in an electric or electronic apparatus is provided, in which a pivoting portion moves with respect to a fixed portion around a hinge portion. Accordingly, the hinge device has effects of a simple assembly and an easy maintenance. Also, the hinge device plays a role of a hinge which can freely adjust a torque transferred to the upper bracket to thus generate a proper frictional force constantly and adjust a rotational angle according to an angle formed by the upper and lower contacting portions of the holder.

Claims

1. A hinge device for use in electric or electronic equipment in which a pivoting portion moves with respect to a fixed portion around a hinge portion, to thereby generate a predetermined pivoting movement according to the movement of the pivoting portion, the hinge device comprising:

a lower bracket;

vertical plates which are vertically and opposingly installed with respect to each other on the central portion of a lower plate, each vertical plate having an inwardly protruding stopper on the upper portion thereof;

a rotational axle around the center portion of which a coil spring is wound to support the lower bracket and an upper bracket, and around an axle groove of which a snap ring is fitted, the rotational axle being placed across the upper portions of the vertical plates, wherein part of each end of the rotational axle is cut to form a cutting face;

a connection plate placed across the upper portions of the vertical plates, the connection plate having a fixing hole and a fixing unit on each end thereof;

a band spring having an engagement unit, which is fitted into each end of the rotational axle, the engagement unit and washers are fixed by a fixing unit and an adjustment bolt, wherein a band cutting face is formed facing the cutting face of the rotational axle; and

the upper bracket having two supporters each of which has a holder including an upper contacting portion and a lower contacting portion which contact the protruding stopper respectively and an axle hole through which the rotational axle is fitted, wherein a plate bearing groove in which a plate bearing is inserted and an adjustment hole through which an adjustment bolt extends are engaged in the inside of the axle hole.
