Abstract

A support stand includes a support member, a friction member, a first connecting bracket, and a second connecting bracket. The support member includes a base portion and two arched plates extending from an end of the base portion. The friction member is rotatably clamped by the arched plates. The first connecting bracket connected to a first end of the friction member. The second connecting bracket connected to a second end of the friction member opposite to the first end. The second connecting bracket is detachably attached to the first connecting bracket.

each of the first and second connecting brackets comprises a main body and an engaging portion connected to the main body;

each engaging portion of the first and second connecting brackets is inserted into the engaging hole from the connecting portions of the friction member.

6. The support stand of claim 5, wherein the friction member uniformly defines a plurality of substantially parallel elongated grooves in an inner surface of the engaging hole;

each of the first and second connecting brackets includes a plurality of substantially parallel elongated protrusions uniformly formed on an outer surface of the engaging portion for latching in the elongated grooves of the friction member.

7. The support stand of claim 6, wherein each main body includes a first base wall, a second base wall, two first side walls, and a second side wall;

the first base wall is substantially perpendicularly connected to a side of the second base wall;

the first side walls extend substantially perpendicularly from opposite sides of the base wall and are substantially perpendicular to the second base wall;

the second side wall is arched in shape and extends substantially perpendicularly from the second base wall and opposite ends of the second side wall are connected to the first side walls.

8. The support stand of claim 7, wherein each engaging portion is substantially a hollow cylinder extending substantially perpendicularly from an inner surface of the second base wall.

9. The support stand of claim 7, wherein the first connecting bracket comprises a plurality of positioning pieces extending from an end portion of the first base wall away from the second base wall;

the second connecting bracket defines a plurality of positioning holes an end portion of the first base wall away from the second base wall;

the positioning pieces engage in the positioning holes.

10. The support stand of claim 7, wherein the first connecting bracket comprises a latching hook formed an end portion of each first side wall away from the second base wall;

the second connecting bracket defines a fixing groove in an inner surface of each first side wall to engage with the latching hook of the first connecting bracket.

11. The support stand of claim 3, wherein the support member further comprises a first fixing portion extending from one of the arched plates, and a second fixing portion extending from the other one of the arched plates;

the first and second fixing portions are plate-shaped and substantially parallel to each other;

the first fixing portion defines two through holes and the second fixing portion defines two threaded holes;

the support stand further comprises two fixing members passed through the through holes, and screwed in the threaded holes so that a clamping force between the arched plates and the friction members is adjustable by adjusting the tension of the fixing members.

12. The support stand of claim 11, wherein the support stand further comprises a torsion spring comprising two spring coils, a connecting arm connecting the spring coils, and a resisting end extending from each of the spring coils;

the spring coils are sleeved on the connecting portions, the connecting arm abuts one of the first fixing portion and the second fixing portion, and the resisting ends respectively abut the first connecting bracket and the second connecting bracket.

13. The support stand of claim 1, wherein the first and second connecting brackets are made of a rigid plastic and the friction members are made of a soft plastic.

14. A flat-panel display monitor, comprising:

a display body comprising a support portion formed at an edge thereof; and

a support stand connected to the display body so that the support portion of the display body and the support cooperatively support the flat-panel display monitor, the support stand comprising;
