At least one movable arm means 2 is slidably attached to the rods by virtue of connecting bases 26. The arm means comprises two arm portions 22,23 pivotally connected to the connecting bases at one end and pivotally connected to a third arm portion 21 at the other end. The third arm portion is pivotally connected to a monitor fixing frame 35 at its distal end. A rotatable wedging device 28 associated with the connecting bases ensures tat the connecting bases can be secured to the sliding rods. By adjusting the movable arm means 2 and the connection means 3, the monitor (4, figs 6,7) can be adjusted to different angles. The bracket may comprise two movable arm means (figs 8,9).

Description

WALL MOUNTED MONITOR BRACKET

The present invention relates to a monitor bracket, and more particularly to a wall mounted monitor bracket that firmly and easily adjusts a monitor to different angles by adjusting a movable arm means and a connection means.

The commercial monitor bracket is generally composed of two parts including a base disposed on the table and an angle-adjustable movable arm coupled with the base, wherein a monitor is fixed on one end of the movable arm such that the monitor can be disposed stably and the monitor's angle is

adjustable.

However, the drawbacks existing in angle adjustment and integral assembly of the conventional monitor bracket are listed as follows: 1. In the process of coupling a plug of a computer machine with the monitor, the monitor or the movable arm must be detached first since the elevational angle of the monitor is not adjustable, causing the inconvenience to the user.

2. An accidental fall of the bracket including the monitor fixed thereon from the table may be caused easily by shifting the bracket or impacting the bracket incautiously, so it is unsteady and not safe enough.

3. The adjustment of the movable arm is confined to specific angles so the adjustable angle is incomplete, causing the inconvenience to the user.

It is a main aim of the present invention to provide a wall mounted monitor bracket for firmly and easily adjusting the monitor to different angles.

In order to achieve the above aim, a wall mounted monitor bracket comprises a sliding base means, at least a movable arm means, and at least a connection means. The movable arm means is hung on the sliding base means via one end, and connected to the connection means via the other end. The other end of the connection means is attached to a first monitor. By adjusting the movable arm means and the connection means, the first monitor can be firmly and easily adjusted to different angles.

The invention will now be further described, by way of example. with reference to the drawings in which: FIG. I is an elevational view of a first preferred embodiment of the present invention; FIG. 2 is elevational, exploded view of the first preferred embodiment of present invention; FIG. 3 is elevational, exploded view of the movable arm means of the first preferred embodiment of present invention; FIG. 4 is elevational, exploded view of the connection means of the first preferred embodiment of present invention: *49 FIG. 5 is partial, cross-sectional view of the first preferred embodiment of present invention; FIG. 6 is schematic view showing the operation of the first preferred embodiment of present invention; FIG. 7 is schematic view showing another operation of the first preferred embodiment of present invention; FIG. 8 is an elevational view of a second preferred embodiment of the present invention; and FIG. 9 is schematic view showing the operation of the second preferred embodiment of present invention.
