When the user places the knob 12 in a state where the angle of the monitor is adjusted by moving the sliding plate 18, the guide plate 6 is moved to its original state by the elastic force of the spring 14, The gear portion 20 'is engaged with the rack gear 22 to fix the angle of the monitor.

However, the above-described conventional techniques have the following problems.

As described above, when the user applies a force to the knob 12 to adjust the angle of the monitor, the guide plate 6 is not moved in a direction in which the force is applied, but is moved in a direction . Therefore, there is a problem that the force applied by the user to the knob 12 can not be transmitted to the guide plate 6 completely. Further, since the guide plate 6 is moved in the diagonal direction, the operation is not smoothly performed.

Further, the gear portion 20 'and the rack gear 22 are generally made of a metal material and engaged with each other. Therefore, due to the characteristics of the metal material, friction between the gear portion 20 'and the rack gear 22 is severe and meshing is not smooth.

The hinge plate 30 corresponding to both sides of the knob seating portion 32 is provided with an angle adjusting jaw 38. The angle adjusting jaw 38 is a portion provided on the back surface of the hinge plate 30 for adjusting the angle of the monitor 80. The angle adjusting jaws 38 are formed at regular intervals along the longitudinal direction of the hinge plate 30. [ The stopper 56, which will be described below, is selectively hooked to the angle adjusting jaw 38. [ Therefore, the angle of the monitor varies depending on the position of the stopper 56 hooked on the angle adjusting jaw 38. [ The angle adjusting jaw 38 is formed with an inclined surface 38 '(see FIG. 4B) formed to be inclined in a direction opposite to the inclined surface 34' of the inclined jaw 34. Reference numeral 39 denotes a through hole into which a screw for fixing the monitor 80 is inserted.

A knob plate (40) is movably installed on the knob seating portion (32) of the hinge plate (30). The knob plate 40 is a part operated by the user when the angle of the monitor 80 is adjusted. To this end, the knob plate (40) is provided at the upper end thereof with an operation portion (42) for the user to hold by hand. The operating portion 42 extends in a direction orthogonal to the upper end of the knob plate 40.

The sliding protrusion is inserted into the sliding groove 53 to guide the movement of the connecting plate 50.

A stopper shaft 54 (see Fig. 4A) is rotatably installed between the movable arms 52. [ At both ends of the stopper shaft 54, a stopper 56 selectively hooked to the angle adjusting jaw 38 is provided. The stopper 56 is hooked on the angle adjusting jaw 38 so that the monitor 80 can be fixed at a predetermined angle. The stopper 56 and the angle adjusting jaw 38 are preferably made of a synthetic resin material for smooth rotation of the stopper 56.

An interlocking cam 58 is provided at the center of the stopper shaft 54. The interlocking cam (58) is a portion which contacts one surface of the knob plate (40). When the knob plate 40 is moved in a rearward direction on the inclined jaw 34 during the movement of the knob plate 40, the interlocking cam 58 rotates in synchronization with the movement of the knob plate 40, . That is, the interlocking cam 58 rotates the stopper shaft 54 to cause the stopper 56 to come out of the angle adjusting jaw 38. The stopper 56 and the interlocking cam 58 are integrally formed with the stopper shaft 54.

On the other hand, an elastic member 59 is fixed to the stopper shaft 54 by a screw S. One end of the elastic member 59 is fixed to the stopper shaft 54 and the other end is in close contact with the inner surface of the cover 70 to be described below. The elastic member 59 provides an elastic force such that the stopper shaft 54 is rotated in a direction in which the stopper 56 is caught by the angle adjusting jaws 38. In this embodiment, a leaf spring is used as the elastic member 59.

The monitor 80 is rotatably supported by a support bracket 82 that is seated on the floor surface through a monitor hinge 84.

Hereinafter, the operation of the monitor angle adjusting apparatus according to the present invention will be described in detail.

First, the process of adjusting the angle of the monitor by the angle adjuster of the monitor according to the present invention will be described. 4A and 4B are a side sectional view and a cross-sectional perspective view showing a state where a stopper is engaged in an angle adjusting device of a monitor according to the present invention.

In this state, the user grips the knob 42 of the knob plate 40 and pulls it upward. The user is pulled out while overcoming the elastic force of the elastic member (not shown) supported at the lower end of the knob plate 40.

During the movement of the knob plate 40, the knob plate 40 moves along the inclined surface 34 'of the inclined jaw 34 as shown in FIG. 5A. That is, the knob plate 40 is protruded rearward of the hinge plate 30. Accordingly, the interlocking cam 58 which has been in contact with the knob plate 40 is rotated, and the stopper shaft 54 is rotated together with the interlocking cam 58. At this time, the interlocking cam 58 and the stopper shaft 54 are rotated while overcoming the elastic force of the elastic member 59 whose one end is supported by the inner surface of the cover 70.

When the stopper shaft 54 is rotated as described above, the stopper 56 integrally formed with the stopper shaft 54 is also rotated. When the stopper 56 is rotated, the stopper 56 is pulled out from the angle adjusting jaw 38 as shown in FIG. 5B. As the stopper 56 is released, the connecting plate 50 can move relative to the hinge plate 30. [0053] As shown in FIG.

The user adjusts the angle of the monitor 80 while moving the connection plate 50 relative to the hinge plate 30 while rotating the connection plate 50 with respect to the support plate 60. When the user is positioned at an angle desired by the user, the operating portion 42 of the knob plate 40 is placed. Then, the knob plate 40 is returned to the original state by the restoring force of the elastic member provided at the lower end of the knob plate 40.

The stopper shaft 54 is also rotated to the original state by the restoring force of the elastic member 59 and the stopper 56 is hooked on the angle adjusting jaw 38 (see FIG. 4B) . 6A and 6B show how to control the angle of the monitor 80 by manipulating the operating portion 42. FIG.

As described above, all the force applied by the user for moving the knob plate 40 is transmitted to rotate the stopper shaft 54. Therefore, it is possible to adjust the angle of the monitor 80 with a minimum amount of force. Also, since the stopper 56 and the angle adjusting jaw 38 are made of synthetic resin and made in contact with each other, the angle adjusting device can be smoothly and smoothly operated.

The scope of the present invention is not limited to the embodiments described above, but may be defined by the scope of the claims, and those skilled in the art may make various modifications and alterations within the scope of the claims It is self-evident.
