Description

Angle control apparatus with hinge

The present invention relates to an angle adjusting device using a hinge, and in particular, by using a metal washer and a synthetic resin washer having a different friction coefficient, the object can be easily adjusted at a constant angle, and also using a hinge that simplifies the component. It relates to an angle adjusting device.

Currently, the flagship product of the display apparatus is the LCD. These LCDs are thin and flat, and because of their thinness, only about one-tenth of the area occupied by conventional CRT (Cathode Ray charge-storage tube) monitors are used. Occupy. Therefore, while the working space of the desk is increased, the work efficiency is improved, and the resolution of the screen is reduced by the light incident from the side of the convex surface of the CRT used in the conventional CRT monitor. Even when light is incident, clear resolution is displayed.

1 is an exploded perspective view showing an angle adjusting device of the LCD monitor according to the prior art.

In general, the LCD monitor 1 is fixedly supported on the front case 2 and the rear case 3 and the front case 2 which are coupled to the front case 2 to form the appearance of the monitor 1. LCD panel (not shown) to display characters or symbols by an electric signal applied from a main printed circuit board (not shown) mounted on the rear case 3, and the monitor 1 in the vertical direction It is configured to include a stand (5) which is pivotally hinged to the rear surface of the rear case (3) so as to be tiltable.

At this time, the lower end of the frame 6 connecting the monitor 1 and the stand 5 is integrally fixed to the stand 5 described above so as to tilt the LCD monitor 1 toward the user (or the frame). The lower end of the (6) is pivotally hinged to the stand (5), the upper end of the frame (6) is fixed to the yoke (4) formed integrally on the back of the rear case (3) described above fixed shaft (7) And rotatably hinged by the mutual tightening force of a plurality of metal washers 8 which are disposed on both left and right sides of the yoke 4 and are in close contact with each other (or fixed integrally to the rear surface of the rear case 3).

However, the tilt torque of the frame 6 hinged to the rear of the rear case 3 so as to tilt the LCD monitor 1 is applied to the mutual tightening force of the fixed shaft 7 and the washer 8 made of metal. By adjusting, the user cannot freely tilt the LCD monitor 1 to facilitate monitoring.

That is, in the above-described hinge structure of the LCD monitor 1, when the tilt torque values of the fixed shaft 7 and the washer 8 are set too high, the LCD monitor 1 may be predetermined so that the user can monitor in an optimal posture. It is difficult to manipulate it so that it can be tilted at an angle.

On the contrary, when the tilt torque values of the fixed shaft 7 and the washer 8 are set too low, the LCD monitor 1 is easily tilted against the user's intention by an impact or contact applied from the outside. Will have

In addition, in the hinge structure as described above, the cost cost is increased due to the increase in the number of parts forming the hinge portion, and the price competitiveness is lost in the same industry field, and the overall work process for assembling these parts is increased. You will have this problem of falling significantly.

The present invention has been proposed in order to solve the problems of the prior art as described above, in the angle adjusting device using a hinge, the hinge so that the tilt torque can be easily adjusted by the mutual frictional force of the metal material and the synthetic resin material having a different friction coefficient The purpose is to provide an angle adjusting device using.
