Description

Hinge assembly of L.C.D monitor

The present invention relates to a hinge assembly for an L.C.D monitor, and more particularly, to a smooth opening of the monitor, and an improvement of the hinge assembly for maintaining at an angle after opening.

In general, the notebook computer is configured such that the main body and the monitor are largely reduced by greatly reducing the size of the notebook computer while keeping the functions of a normal personal computer as it is, for the user to carry.

The main body and the monitor are folded to each other through the hinge to open the monitor upwards only in use so that the user can recognize the image of the monitor.

At this time, the monitor facilitates smooth operation and maintains the state at a certain angle after opening through a hinge interposed for fastening and rotation with the main body.

The hinge has a structure in which a bracket for fastening the main body and the monitor about a hinge axis, a spring for rotating torque, and various elastic bodies are formed by screwing.

This hinge has a problem that it is difficult to maintain the angle of the monitor due to the reduction of the rotational torque caused by the friction between the various elastic bodies, including the spring due to the repeated and continuous use of the notebook computer after the initial installation.

In addition, the rotational torque as well as the compression force causes a sharp drop in the open holding force drastically leads to a situation in which the user cannot see the monitor normally.

In addition, as the monitor of the computer has evolved from the CRT type to the L.C.D type, the same problems as those of the notebook computer described above frequently occur.

Thus, in recent years, hinge structures of notebook computers and L.C.D monitors have been devised and used to solve the above problems.

This is also the situation that the effectiveness of the effect is not greatly exhibited due to the difficulty of correction of the initial rotational torque and the opening holding force.

Accordingly, the present invention has been made to solve the various problems described above, by providing a hinge assembly through the elastic body for the action of the uniform rotation torque in the bracket for fastening the main body and the monitor to set the correct opening position of the monitor,

It aims to improve the user's convenience and durability of the monitor by making it possible to compensate for the reduction of rotational torque due to wear.
