Description

Section 2 Support Assembly for Flat type Monitor having 2-joint type hinge}

The present invention relates to a pedestal assembly for rotatably supporting a flat panel monitor, and more particularly, to a pedestal assembly of a flat panel monitor having a two-stage hinge structure to adjust the tilt angle and height of the monitor in a dual rotation method.

In general, in order to use flat panel monitors such as liquid crystal display (LCD) monitors on a desk or a desired place, a pedestal for supporting the monitor is required.

These pedestals are coupled via a hinge assembly to the rear of the monitor so that the user can adjust the monitor's inclination angle to a desired angle. The hinge assembly is a spring which allows the monitor's inclination angle to be adjusted by the elastic force and the friction force of the spring. Friction-type hinge assemblies and assemblies using one-way roller clutches are used.

The spring- friction type hinge assembly is mainly used when the rotation angle is about 35 to 45 degrees, and the change in the center of gravity does not occur much. The roller clutch type hinge assembly makes the distribution of the force by the load uniform. Apply for smooth operation.

However, conventional monitor pedestals using the hinge assemblies as described above have a limited bearing capacity when the hinge assembly of the spring-friction type is selected, and thus, the inclination angle is limited. When the roller clutch type hinge assembly is selected and used, There is a disadvantage that the sufficient support capacity and easy to adjust the inclination angle, but the roller clutch is expensive and height adjustment is impossible.

Therefore, the present invention has been made to solve the above problems, smooth and easy to operate the inclination angle adjustment of the flat panel monitor and ensure sufficient support force to adjust the inclination angle any angle and at the same time smoothly even the height adjustment It is an object of the present invention to provide a pedestal assembly of a flat panel monitor having a two-section hinge structure that can be achieved.

In order to achieve the above object, the present invention, the base plate is placed on the bottom surface, rotatably installed on one end of the base plate and the lower hinge assembly to adjust the torque by the elastic force and friction force of the spring and the one-way roller clutch And an upper hinge assembly rotatably installed on the rear portion of the monitor and configured to adjust torque by elastic force and friction force of a spring, and one end of which is rotatably coupled to the lower hinge assembly, and the other end of which is rotatably coupled to the upper hinge assembly. Provided is a pedestal assembly for a flat panel monitor having a two-section hinge structure including a support member.

According to one aspect of the invention, the upper hinge assembly is composed of a spring-fraction type hinge assembly, the lower hinge assembly is composed of a structure in which the spring- friction type and the one-way roller clutch type hinge assembly is applied simultaneously.

Hereinafter, a preferred embodiment of the pedestal assembly of the flat panel monitor according to the present invention will be described in detail.

1 shows a flat panel monitor to which a pedestal assembly of the present invention is applied, and a lower hinge assembly 40 is rotatably installed at a rear end of a base plate 20 placed on a bottom surface of a desk or a table. An upper hinge assembly 30 is rotatably installed on the rear portion of the monitor 10 to adjust torque by elastic force and friction force of a spring, and a lower end portion of the support member 50 is coupled to the upper hinge assembly 30. And the upper hinge of the support member 50 is coupled to the lower hinge assembly (40).

The upper hinge assembly 30 is composed of a so-called spring-fiction type hinge assembly that adjusts the torque by the elastic force and the friction force of the spring, as shown in Figure 2, the upper hinge assembly 30 is made of the same The first upper hinge assembly 31 and the second upper hinge assembly 32 are provided to face each other at regular intervals.

The first upper hinge assembly 31 may be formed by a first fixing bracket 311 fixed to the rear portion of the monitor 10 by a fastening means such as a screw (not shown), and a fastening means such as a screw (not shown). The first connecting bracket 312 is fixed to the support member 50, the first connecting bracket 312 of the first rotating shaft 313 coupled to pass through one end of the first fixing bracket 311 The outer end is fixedly coupled, the first fixing rib 314 is coupled to the inner end of the first rotation shaft 313, between the first fixing rib 314 and one end of the first fixing bracket 311 The first end is composed of a first torsion spring 316 is supported by the first fixed rib 314 and the other end is supported by the first fixing bracket 311.

A support washer 315 for supporting an outer surface of one end of the first fixing bracket 311 is coupled to a middle portion of the first rotation shaft 313 to which one end of the first fixing bracket 311 is coupled.

Therefore, when the user applies an external force to the monitor 10 to adjust the inclination angle, the first fixing bracket 311 coupled with the monitor 10 rotates about the first rotation shaft 313 and the first torsion spring 316. ) Compresses or expands to generate elastic force. When the monitor 10 is inclined at a desired angle and the user removes the external force, the elastic force of the first torsion spring 316 and the force due to the center of gravity of the monitor 10 While maintaining the balance, the monitor 10 is kept in an inclined state.

Preferably, the rotation angle operating range of the monitor 10 by the upper hinge assembly 30 is about 145 °.

Since the second upper hinge assembly 32 is configured and operates in the same manner as the configuration of the first upper hinge assembly 31, detailed description thereof will be omitted.

On the other hand, the lower hinge assembly 40 is a mixture of the spring- friction type and roller clutch type hinge assembly to adjust the torque by the spring force and the frictional force and the one-way roller clutch, as shown in Figure 3 A pair of the first base bracket 401 and the second base bracket 402 and the base plate 20 are installed so as to face each other at a predetermined interval apart from each other and rotatably installed on the first base bracket 401. The first rotary shaft 405, a fixed rib 407 coupled to the middle portion of the first rotary shaft 405, one end is supported by the first base bracket 401, the other end is fixed rib 407 A first torsion spring 408 coupled to an outer end of the first rotation shaft 405 and fixed to an inner end of the first rotation shaft 405 so as to be supported by the first rotation shaft 405 and coupled to the support member 50. On the connection bracket 410 and the second base bracket 402 A bearing housing 403 fixed to the end, a roller clutch 404 installed to rotate only in one direction (arrow direction), and fixed to a rotating part of the roller clutch 404. A second rotating shaft 406, a pair of friction disks 408 fixedly coupled to an inner end of the second rotation shaft, and one end of an inner surface of each friction disk 408 between the friction disks 408. It is coupled to be in close contact with the other end is configured to include a second connection bracket 411 is coupled to the support member (50).

For reference, the one-way roller clutch 404 is also commonly referred to as a one-way bearing, in which a plurality of balls are arranged therein so that the ball rotates in one direction and smoothly rotates in one direction, but when the ball is operated in the opposite direction. It is a component having an operating principle that is tightened in the rotational direction and fixed to prevent rotation.

Therefore, when the user exerts an external force on the monitor 10 to raise the support member 50 with respect to the base plate 20, that is, the angle between the base plate 20 and the support member 50 increases, the second As the roller clutch 404 coupled to the rotating shaft 406 rotates smoothly without load in the direction of the arrow, the support member 50 rises, and when the user removes the external force when the desired angle is reached, the roller clutch 404 is reversed. Since it does not rotate in the direction, the support member 50 is maintained in that state without being lowered or sag again by the load of the monitor 10.

When the support member 50 ascends as described above, the torsion spring 408 coupled to the first rotating shaft 405 on the opposite side is expanded to assist the ascending operation of the support member 50, thereby smoother and smoother ascending operation. This can be done.

On the contrary, when the support member 50 is to be lowered, the user presses the monitor 10 or the support member 50 downward.

At this time, since the roller clutch 404 cannot be rotated in the opposite direction, the second rotating shaft 406 is kept in a fixed state, and the second connection bracket 411 coupled to the support member 50 is The friction disk 408 is rotated about the second rotation shaft 406 while in frictional contact. At this time, the first connecting bracket 410 rotates the first rotation shaft 405, and thus the torsion spring 408 is contracted to apply an elastic force in the opposite direction of rotation.

On the other hand, when the user wants to adjust the inclination angle of the monitor 10 in the state of the monitor shown in FIG. 1, as shown in FIGS. 4A and 4B, the user grasps the top of the monitor 10 and flips back or forwards. When the pulling operation is performed, the upper hinge assembly 30 is operated so that the monitor 10 rotates with respect to the support member 50 and the inclination angle is adjusted. At this time, when the user presses or pushes up the monitor 10, the support member 50 is rotated about the lower hinge assembly 40, and the height of the monitor 10 is also adjusted.

In addition, when the user does not use the monitor 10 or wants to adjust the height of the monitor as needed, the monitor 10 may be completely folded as shown in FIG. 4C.

As described above, according to the present invention, the lower hinge assembly is applied by mixing the spring-friction type and the roller clutch type hinge assembly, and the upper hinge assembly is applied to the spring-fraction type hinge assembly to provide a pedestal assembly. By constructing the hinge structure, it is possible to secure a sufficient support capacity of the monitor and at the same time ensure a smooth and smooth rotation angle adjustment operation, it is possible to easily adjust the tilt angle as well as the height of the monitor with one pedestal assembly.
