Supporting device for display units

Abstract

A supporting device for display units enables height adjustment with ease and accuracy, and stably maintains the adjusted height while allowing a plurality of display units to be mounted thereon. The supporting device includes a stationary member, an elevation member coupled to the stationary member so as to be raised or lowered, a rack gear secured to the stationary member, a pinion gear installed to the elevation member so as to engage with the rack gear, and a restriction unit installed to the elevation member to restrict or allow rotation of the pinion gear. The supporting device further comprises an upper-side supporting member installed to an upper portion of the elevation member, first and second movable members to move along a guide rail of the upper-side supporting member, and connecting devices installed to the respective movable members to connect the display unit, respectively.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority under 35 U.S.A. §119 of Korean Patent Application No. 2006-0021012, filed on Mar. 6, 2006 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a supporting device for display units, and, more particularly, to a supporting device for display units, which can adjust a height of the display unit with accuracy, maintain the adjusted height thereof with stability, and allows display units having different weights to be selectively mounted thereon.[0004]2. Description of the Related Art[0005]Generally, a display unit such as a liquid crystal display and a plasma display panel is supported by a supporting device, which can stably support the panel, and allow adjustment in height of the panel. One example of such a supporting device is disclosed in Korean Utility Model...

AI Technical Summary

Benefits of technology

[0010]Accordingly, it is an aspect of the present invention to provide a supporting device for display units, which enables adjustment in height of a display unit with ease and accuracy, and stably maintains the adjusted height of the display unit while allowing display units having different weight to be selectively mounted thereon.

[0011]It is another aspect of the present invention to provide the supporting device, which allows a plurality of display units to be used in a mounted state thereon, and enables easy adjustment of distance and installation angle between the display units.

Problems solved by technology

However, since the elasticity of the spiral spring of the supporting device is predetermined, there is a problem in that, if other display units having different weights from that of a standard display unit are mounted on the supporting device, equilibrium between the elasticity of the spiral spring and the weight of the display unit is disrupted, causing the supporting device not to exhibit the height adjustment function.

As a result, the supporting device cannot be commonly used for the display units having different weights.

However, such a supporting device has a problem in that, since fixing grooves are separated a great distance from each other on a side surface of a fixing part, and since height adjustment positions are restricted to locations of the fixing grooves, adjustment in height of the display unit cannot be performed with accuracy.

However, since it is necessary, for use of the stand, to fasten or release fastening screws or nuts whenever installation angles of the display units or separation distances therebetween are adjusted, the stand has a difficulty in adjustment of the installation angles and the separation distances therebetween.

Accordingly, it is inconvenient to use such a stand in such a case where the adjustment in distance between the display units is frequently required.
