Abstract

An automatically adjusting support for an LCD monitor is composed of a bottom seat, an elevating part, a rotating part, a longitudinally moving part, and an installing plate. An LCD monitor secured on the installing plate can be adjusted in height by the elevating part, at a horizontal angle by the rotating part, and at a vertical angle by the longitudinally moving part.

Claims

1. An automatically adjusting support for an LCD monitor comprising:

an elevating part (20) having a vertical threaded shaft (21) extending through the bracket (11), a first elevating gear (22) and a second elevating gear (23) engaged with each other and provided between the bracket (11) and the upper plate (14), an elevating motor (24) for driving the first elevating gear (22) mounted beneath the upper surface of the bracket (11) and connected to the first elevating gear (22), the vertical threaded shaft (21) threadingly engaged in the second elevating gear (23) and having an upper end (212);

a rotating part (30) having a linking member (36) mounted on the upper end (212) of the elevating threaded shaft (21), an immobile plate (32) secured on the linking member (36), a mobile plate (31) above the immobile plate (32), a first horizontally adjusting gear (33) and a second horizontally adjusting gear (34) engaged with each other and provided between the mobile plate (31) and the immobile plate (32), the second vertically adjusting gear (34) secured to the mobile plate (31), and a horizontally adjusting motor (35) for driving the first horizontally adjusting gear (33) mounted beneath the immobile plate (32) and connected to the first horizontally adjusting gear (33);

a longitudinally moving part (40) having a U-like seat (41) formed with two upright portions and a lateral portion between the upright portions and mounted on the mobile plate (31), two first ears (411) respectively formed on the upright portions of the U-like seat (41), a gear carrier (42) provided on the lateral portion of the U-like seat (41), a vertically adjusting motor (43) mounted beside the gear carrier (42), a worm (431) connecting to the vertically adjusting motor (43), a vertically adjusting gear (44) rotatably mounted in the gear carrier (42), and a horizontal threaded shaft (45) threadingly engaged in the vertically adjusting gear (44); and

an installing plate (50) having two second ears (51) formed at a backward surface thereof and respectively pivotally mounted with the first ears (411), two third ears (53) formed below the second ears (51), two elongated holes (531) respectively defined through the third ears (53), and the horizontal threaded shaft (45) having a forward end (451) pivotally mounted between the third ears (53) by fasteners inserted through the elongated holes (531).

2. The automatically adjusting support as claimed in claim 1, wherein the bottom seat (10) has a first elevating limit switch (12) and a second elevating limit switch (13) mounted in the bracket (11), and the vertical threaded shaft (21) has a vertical stop disk (211) provided at a lower end thereof.

3. The automatically adjusting support as claimed in claim 1, wherein the rotating part (20) has a first horizontally adjusting limit switch (37) and a second horizontally adjusting limit switch (38) mounted on the mobile plate (31) and respectively at two sides of the second gear (34).

4. The automatically adjusting support as claimed in claim 1, wherein the longitudinally moving part (40) has a first vertically adjusting limit switch (46) and a second vertically adjusting limit switch (47) mounted behind the U-like seat (41), and the horizontal threaded shaft (45) has a horizontal stop disk (451) provided at a backward end thereof.

5. The automatically adjusting support as claimed in claim 1, wherein the vertical threaded shaft (21) having a channel (213) longitudinally defined at an outer periphery thereof, and the bottom seat (10) has a guide sheet (16) mounted on the upper plate (14) and having a lug located in the channel (213) of the vertical threaded shaft (21).

6. An automatically adjusting support for an LCD monitor comprising:

a fixed seat (60) having a C-like section formed with an upper portion (601), a lower portion (602) parallel to the upper portion (601), and a fixed portion (603) between the upper portion (601) and the lower portion (602);

a rotating part (30) mounted on the fixed seat (60), the rotating part (30) having a mobile plate (31) above the upper portion (601), a first horizontally adjusting gear (33) and a second horizontally adjusting gear (34) engaged with each other and provided between the mobile plate (31) and the upper portion (601), the second vertically adjusting gear (34) secured to the mobile plate (31), and a horizontally adjusting motor (35) for driving the first horizontally adjusting gear (33) mounted beneath the upper portion (601) and connected to the first horizontally adjusting gear (33);

a longitudinally moving part (40) having a U-like seat (41) formed with two upright portions and a lateral portion between the upright portions and mounted on the mobile plate (31), two first ears (411) respectively formed on the upright portions of the U-like seat (41), a gear carrier (42) provided on the lateral portion of the U-like seat (41), a vertically adjusting motor (43) mounted beside the gear carrier (42), a worm (431) connecting to the vertically adjusting motor (43), a vertically adjusting gear (44) rotatably mounted in the gear carrier (42), and a horizontal threaded shaft (45) threadingly engaged in the vertically adjusting gear (44); and

an installing plate (50) having two second ears (51) formed at a backward surface thereof and respectively pivotally mounted with the first ears (411), two third ears (53) formed below the second ears (51), two elongated holes (531) respectively defined through the third ears (53), and the horizontal threaded shaft (45) having a forward end (451) pivotally mounted between the third ears (53) by fasteners inserted through the elongated holes (531).
