Abstract

A stand for an LCD monitor with a back is composed of a locking member, a first pivoting member, a second pivoting member, a monitor bracket, a base and two base brackets. The monitor bracket is attached to the back of the LCD monitor. The pivoting members are securely attached to the base brackets on the base. The monitor bracket can be pivoted relative to the base by using the pivoting members, so that the LCD monitor is folded to reduce its overall volume for packing, storing or transporting.

Claims

1. A stand for an LCD monitor comprising:

a monitor bracket (40) adapted to be connected to the back of an LCD monitor, the monitor bracket (40) having

a bar (41) with two ends for attaching the stand to the LCD monitor;

a first ear (42) with a bottom and a top formed perpendicular to the bar (41) at one end of the bar (41);

wherein the first ear (42) has an arcuate notch (421) defined at the bottom of the first ear (42), a first pivot hole (420) defined substantially concentric with the arcuate notch (421) through the first ear (42), a slot (422) defined above the first pivot hole (420) and a keyed hole (423) defined above the slot (422); and

a second ear (43) with a bottom and a top formed perpendicular to the bar (41) at the other end of the bar (41);

wherein the second ear (43) has a second pivot hole (430) defined through the second ear (43) and aligned with the first pivot hole (420);

a first pivoting member (20) pivotally mounted on the first ear (42), the first pivoting member (20) having

a first pivot pin (21) with two ends, a first enlarged head (210), a first keyed shaft (212) and a first transverse flange between the first enlarged head (210) and the first keyed shaft (212), the first keyed shaft (212) having an external thread and extending through the first pivot hole (420);

a first nut (26) screwed onto the external thread of the first keyed shaft (212);

a positioning disk (22) with a bottom mounted around the first keyed shaft (212) between the first ear (42) and the first transverse flange of the first pivot pin (21), the positioning disk (22) having an irregular outer circumference, a lug (220) formed at the bottom of the outer circumference and extending into the arcuate notch (421) on the first ear (42), a keyed central hole and a limit (222) formed on the outer circumference of the positioning disk (22);

a first damper (25) mounted around the first keyed shaft (212) between the first ear (42) and the first nut (26);

two first flat washers (24) respectively mounted around the keyed shaft (212) at two sides of the first damper (25); and

two pairs of first gaskets (23) respectively mounted around the keyed shaft (212) at two sides of the first ear (42);

a second pivoting member (30) pivotally mounted on the second ear (43), the second pivoting member (30) having

a second pivot pin (31) with two ends, a second enlarged head (310) formed at one end, a second keyed shaft (312) formed at the other end with an external thread and a second transverse flange between the second enlarged head (310) and the second keyed shaft (312), the second keyed shaft (312) extending through the second pivot hole (430);

a second nut (35) screwed onto the external thread of the second keyed shaft (312);

a second damper (34) mounted around the second keyed shaft (312) between the second ear (43) and the second nut (35);

two second flat washers (33) respectively mounted around the keyed shaft (312) at two sides of the second damper (34); and

two pairs of second gaskets (32) respectively mounted around the keyed shaft (312) at two sides of the second ear (43);

a locking member (10) mounted on the first ear (42), the locking member (10) having

a sleeve (16) having an outer surface, two ends, an enlarged flange on one end, an outer thread at the other end and a longitudinal keyed surface on the outer surface mounting in and extending through the keyed hole (423) in the first ear (42);

a third nut (13) screws onto the outer thread of the sleeve (16) to hold the sleeve (16) in the keyed hole (423);

a rod (11) with two ends composed of a first part with a large outer diameter at one end and a second part with a small outer diameter at the other end, the second part of the rod (11) having an external thread and a keyed surface extending through the sleeve (16);

a fourth nut (18) screws onto the external thread of the second part of the rod (11);

a latch (17) mounted around the rod (11) between the sleeve (16) and the fourth nut (18), the latch (17) having a bottom edge and a tongue (170) formed at the bottom edge of the latch (17) and extending through the slot (422) in the first ear (42) and over the positioning disk (22);

a biasing member (12) mounted around the second part of the rod (11) between the first part of the rod (11) and the third nut (13);

a third damper (15) mounted around the rod (11) between the first ear (42) and the third nut (13); and

a third flat washer (14) mounted around the rod (11) between the third nut (13) and the third damper (15); and

a base (50) with two brackets (52) formed upright on the base (50) to which enlarged heads (210, 310) of the pivoting members (20, 30) are securely attached.

2. The stand as claimed in claim 1, wherein the tongue (170a) of the latch (17a) further has an arced edge (172a).

3. The stand as claimed in claim 1, wherein each of the dampers (25, 34, 15) includes at least two resilient dished washers.
