Abstract

A supporting device for a liquid crystal display includes a clip fixed to a frame, a base secured to the clip, an arm pivotally linked to the base, an adjustment device installed in the base, a cylinder device contained in the arm and pivotally linked to the adjustment device, and a positioning device formed on the top of the arm. The adjustment device has a simple structure and is able to adjust an angle of the cylinder device with respect to the arm to support displays of different weight.

Claims

1. A supporting device for a liquid crystal display, the device having a clip, a base secured to the clip, an adjustment means installed in the base, an arm pivotally linked to the base, a cylinder means contained in the arm and pivotally linked to the adjustment means, a positioning means formed on a top of the arm, the cylinder means having a shaft contained in a shaft tube, wherein the improvements comprise:

the base being substantially U shaped and having a pair of ears on which the arm is pivotally linked by a pin;

the adjustment means having a top plate formed on the pair of ears of the base, a bar formed in the base and having a C-shaped direction groove, and, a slidable seat having a top surface, a front surface, and a rear surface, the top plate being retainable at a certain angle with respect to the base, the top plate having an opening, a pair of ears being formed on the front surface of the slidable seat, a threaded hole being defined in the top surface of the slidable seat, a direction bar being formed on the rear surface of the slidable seat, a long bolt having a neck with a diameter smaller than a diameter of a shaft thereof, a leaf having a recess being able to receive the neck of the long bolt, wherein in assembly, the direction bar is inserted and slidably received in the C-shaped direction groove, a free end of the shaft of the cylinder means is pivotally linked to the pair of ears of the slidable seat, the long bolt is inserted through the opening and threadedly engages with the threaded hole in the slidable seat, and finally the lead is fixed to the top plate with the recess thereof abutting the neck of the long bolt.

2. The supporting device as claimed in claim 1, wherein the positioning means has a bar-like lower connecter and an upper connecter, the lower connecter having a top traverse through opening and a bottom traverse through opening, the upper connecter having a top disc formed on a top surface thereof and the disc having a bolt formed thereon, and a pair of ears formed on a bottom surface of the disc, the lower connecter being pivotally linked to the top of the arm by a pin inserted through the bottom opening thereof and a pair of ears formed on the top of the arm, and the upper connecter being pivotally linked to the lower connecter by a pin inserted through the ears thereof and the top opening of the lower connecter, whereby the bolt extends through a central opening defined in a fixing plate and then threadedly engages with a nut, wherein the fixing plate is able to be installed onto a display.

3. The supporting device as claimed in claim 2, wherein the bolt has at least one plane parallel to an axis of the bolt, and the central opening in the fixing plate has at least one flat corresponding to the at least one plane in the bolt, and when the bolt is inserted through the central opening, the at least one flat abuts the plane thereby securing the fixing plate in a non-rotatable mode with respect to the bolt.
