Referring to these drawings, the horizontal rotating device for a video display device of the present invention includes a fixed stand 10 fixed to a video display device such as a monitor or TV, a support 20 for supporting the video display device, and the fixed stand. And a hinge assembly A installed between the support 10 and the support 20.

The hinge assembly (A) is a central bracket 30, a fixing bracket 40 fixed to the fixed stand 20 in a state fitted to the shaft through the fixing hole 41, fitted to the shaft and generates a vertical elastic force to the image An elastic washer 60 for maintaining the rotational position of the display device as it is, and a flat washer 50 for preventing wear between adjacent parts.

The center shaft 30 is fixed to the support 20, the lower side is releasable, the upper side of the fixing bracket 40, the flat washer 50 and the elastic washer 60 is inserted into a fixed stand ( It extends into the stand through the bottom part of 10).

Preferably, the central shaft 30 has an upper small diameter portion 31 into which the fixing bracket 40, the flat washer 50, and the elastic washer 60 are fitted, and a lower large weave having a chamfer 31a around the periphery. It is a cylindrical two-stage structure consisting of a neck portion, as will be described later in Figure 3, the upper small diameter portion 21 is formed with an upper flare portion to fix them in a state where the fixing bracket 40, flat washer 50 and elastic washer 60 is fitted have.

The support 20 is formed with a recess 21 into which a large diameter portion of the central shaft is inserted, and the recess 21 has a chamfered surface 21a at a side portion thereof so as to correspond to the shape of the chamfered large diameter portion. And a fixing hole 23 for screwing the central shaft in the bottom portion of the recess.

A stopper protrusion 25 is disposed around the recess 21 to limit the rotation range of the video display device when the fixed stand 10 is rotated horizontally, that is, when the video display device is rotated horizontally. This stopper projection cooperates with a predetermined portion of the fixed stand to limit the rotation range of the video display device, which is described in the description of FIGS. 4 to 6.

The fixed stand 10 is a component fixed to a video display device such as a monitor or a TV, the bottom portion of which is configured for coupling with the hinge assembly A (for example, a configuration or a hinge for accommodating an upper portion of the hinge assembly) And a structure for fixing a screw inserted through the screw insertion port 43 of the fixing bracket 40 of the assembly) (see FIGS. 4 to 6), and the rear portion thereof has a grid-like reinforcement to withstand a large fixed load. It is preferable to form the structure, and for example, a screw fixing hole 17 for engaging with the video display device is formed at the grid intersection point of the grid-shaped reinforcement structure.

3 is a schematic cross-sectional view showing the hinge assembly in an assembled state.

The hinge assembly (A) inserts the fixing bracket 40, the flat washer 50, and the elastic washer 60 in turn into the upper small diameter portion 31 of the central shaft 30, which is composed of two stages, and at the top end of the central shaft. It is formed by forming a flare part 70 to fix the insert parts.

The flare part 70 may be formed by riveting, or may be formed by pressing and fixing a separate fixing ring.

On the other hand, the configuration for limiting the rotation range during the relative horizontal rotation between the fixed stand and the support and the horizontal rotation action according to the configuration is shown in FIGS. 4 to 6.

Figure 4 is a bottom view of the fixed stand, Figure 5 is a schematic cross-sectional view taken along the line BB of the bottom stand of Figure 4, Figure 6 is a horizontal rotation action and horizontal rotation range by the horizontal rotating device for a video display device of the present invention It is a functional diagram which shows by way of example.

Referring to these drawings, the bottom surface of the fixed stand 10 has a space 11 for accommodating the central shaft end portion, a plurality of stopper columns 15 extending longer than the space portion around the space portion, and fixed. A fixing hole 13 for fixing the bracket is formed.

According to one embodiment of the present invention, the remaining portion of the fixed stand is a solid body or a lattice reinforcement structure except for the space portion of the bottom portion thereof, and is suitable for supporting a high fixed load.

Around the recess 21 of the support 20 is provided with stopper protrusions 25 which are arranged in opposition to limit the horizontal rotation range in cooperation with the stopper column 15.

The horizontal rotating device for a video display device of the present invention is completed by assembling the aforementioned components in the following manner.

First, the hinge assembly is assembled, and the fixing bracket of the hinge assembly is fixed to the fixing stand 10 while the assembled hinge assembly is inserted into the space 11 through the bottom of the fixing stand 20, and then the hinge assembly When the lower end of the central shaft of the screw is inserted into the recess of the support 20 and fixed with a screw, the horizontal rotating device for a video display device according to the present invention is completed.

Looking at the operation of the assembled horizontal rotating device for a video display device of the present invention.

The hinge assembly is assembled into one unit by flaring the upper end of the central shaft, and the hinge assembly is fixed to the support stand through the fixing bracket, and then fixed to the support to fix the stand 10, the hinge assembly. Since both (A) and the support 20 are mutually coupled, the relative horizontal rotation between the fixed stand 10 and the support 20 is performed through the hinge assembly.

This horizontal rotation is limited by the stopper column 15 of the fixed stand 10 and the stopper protrusion 15 of the support 20. As shown in FIG. The stopper columns 15 disposed to face each other along the reference line rotate in the direction of the arrow, and when they reach the positions of the stopper protrusions 15 of the supports disposed to face each other along the Y-reference line, the movement is restricted. The horizontal rotation is made only by the angle θ.

Such a horizontal rotation range can adjust the rotation angle according to the number of stopper pillars 15 and the stopper projections 25, arrangement intervals, and the like.

According to the above-described configuration, the present invention is for a video display device that can configure the hinge assembly without performing a complex machining to the central shaft or using separate parts, and can operate with a small force and can adjust the rotation range in a simple configuration Provide a horizontal rotating device.
