Description
BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The invention relates to a wall mount unit; in particular, the invention relates to a wall mount unit that is low-cost and convenient to use.

[0003] 2. Description of the Related Art

[0004] Recently, there have been increasingly improved display devices having a reduced thickness and a larger display area. Among a variety of display devices, plasma display panels (hereinafter referred to as “PDPs”) have a reduced thickness and are readily adapted for color display and for a larger display area. In addition, the PDPs are self-luminant and have excellent visibility. Therefore, the PDPs are promising, for example, as wall-mount large-screen TVs.

[0005] When users want to hang the PDP on a wall, a wall mount unit is needed. There are two kinds of the conventional wall mount units: one with a fixed angle and the other with an adjustable angle. Since the wall mount unit, with a fixed angle, is not suitable for a situation that needs angle-adjustment, it is not practical nowadays.

[0006]FIG. 1 shows a conventional wall mount unit for mounting the PDP. The wall mount unit 10 is consisted of a first support 11, a second support 12 and two pistons 13. The first support 11 is mounted on a wall (not shown) . The second support 12 is rotatably connected to the first support 11 by pins 14 at their bottom portions. The second support 12 is used for mounting the PDP (not shown). The pistons 13 connect the first support 11 and the second support 12 at their upper portion, and the pistons 13 are used as adjusting mechanisms to adjust an angle between the first support 11 and the second support 12. The disadvantage of the wall mount unit 10 is that its cost is too high. Specifically, since two pistons 13 are used, the whole price of the wall mount unit 10 increases.

[0007]FIG. 2 shows the other conventional wall mount unit for mounting the PDP. The wall mount unit 20 consists of a support 21, two supporting stands 22, two links 23, two sliders 24 and two bolts 25. The support 21 is mounted on a wall (not shown). The supporting stands 22 are rotatably connected to the support 21 by pins 26 at their bottom portions. The support stands 22 are used for mounting the PDP (not shown). One end of each link 23 is connected to the supporting stand 22, and the other end thereof is connected to the slider 24. The sliders 24 are disposed on the support 21 in a moveable manner. A plurality of first holes (not shown) are formed on the support 21. A plurality of second holes (not shown), corresponding to the first holes separately, are formed on the sliders 24. The first holes and the second holes are used for the bolts 25 passing through.

[0008] An angle between the support 21 and the supporting stands 22 of the conventional wall mount unit 20 is adjusted by the links 23 and the sliders 24 shown in FIG. 2. After the sliders 24 are moved to a predetermined position to attain a predetermined angle, the bolts 25 are passed through the first holes and the second holes to fix the sliders 24 at the predetermined position of the support 21.

[0009] The disadvantage of the wall mount unit 20 is that it is very inconvenient for the users. Specifically, because the angle between the support 21 and the supporting stands 22 is adjusted by changing the positions of the bolts 25, it is very troublesome for the users. In addition, since each supporting stand is adjusted independently, adjusting time becomes longer.

SUMMARY OF THE INVENTION

[0010] In view of the disadvantages of the aforementioned conventional wall mount units, the invention provides a wall mount unit that can reduce its cost and enhance its convenience.

[0011] Accordingly, the invention provides a wall mount unit for mounting a plasma display panel on a wall. The wall mount unit comprises a first support, a second support and a third support. The first support, having a first end and a second end, is disposed on the wall. The second support, having a link at one end, is rotatably disposed at the first end of the first support at the end with no link. The third support, rotatably disposed at the second end of the first support and provided with at least one guide slot, is used for the plasma display panel mounting thereupon. The link moves in the guide slot to adjust an angle between the first support and the third support.

[0012] Furthermore, the guide slot has a plurality of notches for positioning the link.

[0013] Furthermore, the third support has a plurality of bolt holes for mounting the plasma display panel.

[0014] Furthermore, the first support has a plurality of junction pieces for positioning the first support on the wall.

[0015] Furthermore, the wall mount unit further comprises a plurality of stoppers disposed on the link.

[0016] Furthermore, the invention provides a wall mount unit that comprises at least one first supporting stand, at least one second supporting stand and at least one third supporting stand. The first supporting stand is disposed on a wall. The second supporting stand is rotatably disposed at one end of the first supporting stand at one end. The third supporting stand, having at least one guide slot for the other end of the second supporting stand moving therein, is rotatably disposed at the other end of the first supporting stand. Therefore, an angle between the first supporting stand and the third supporting stand is adjusted.

[0017] Furthermore, the invention provides a wall mount unit that comprises a first support, a third support and a second support. The first support, having at least one guide slot, is disposed on a wall. The third support is rotatably disposed at the first support. The second support, rotatably disposed at the third support at one end, moves into the guide slot at the other end. Therefore, an angle between the first support and the third support is adjusted.

[0018] Furthermore, the invention provides a wall mount unit that comprises at least one first supporting stand, at least one second supporting stand, at least one third supporting stand and at least one fourth supporting stand. The first supporting stand is disposed on a wall. The second supporting stand is rotatably disposed at one end of the first supporting stand at one end.
