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...

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 othe...
