[0033] First embodiment

[0034] As shown in FIG. 3a, a first embodiment of a wall mount unit 30 of the invention comprises a first support 31, a second support 32 and a third support 33. The first support 31 comprises two first supporting stands 312, two fourth supporting stands 313 and a plurality of junction pieces 311. The junction pieces 311 are used to mount the first support 31 on a wall 50 as shown in FIG. 4a. Each fourth supporting stand 313 is used to connect the first supporting stands 312 to one another.

[0035] The second support 32 is disposed at one end (hereinafter also referred to as “a first end”) of the first support 31 in a rotatable manner, and it comprises a first link 321, two second supporting stands 323 and two second links 324. The third support 33 is disposed at the other end (hereinafter also referred to as “a second end”) of the first support 31 in a rotatable manner, and it comprises two third supporting stands 334, a fifth supporting stand 337 and two third links 335. Each fifth supporting stand 337 is used to connect the third supporting stands 334 to one another. Each third supporting stand 334 is provided with a guide slot 331. The first link 321 is moved in the guide slots 331. An angle between the first support 31 and the third support 33 is adjusted by moving the first link 321.

[0036] Referring to FIG. 3a, one end of each second supporting stand 323 is disposed in the third supporting stand 334 by the first link 321, and the other end of each second supporting stand 323 is disposed in the first supporting stand 312 by the second link 324. Each third link 335 connects each first supporting stand 312 and each third supporting stand 334 at their bottom portions.

[0037] The guide slots 331 are provided with a plurality of notches 332 for positioning the first links 321. There are five notches 332 shown in FIG. 3a. After the angle between the first support 31 and the third support 33 is adjusted, the first links 321 are located in the notches 332. Each third supporting stand 334 of the second support 33 is provided with a plurality of bolt holes 333. There are two bolt holes 333 formed on the third supporting stands 334 respectively shown in FIG. 3a. The upper portion of each bolt hole 333 is bigger than the lower portion thereof.

[0038] Furthermore, each first supporting stand 312 of the first support 31 is provided with a plurality of junction pieces 311. There are three junction pieces 311 shown in FIG. 3a. The junction pieces 311 are used to fix the first support 31 on the wall 50 which shown in FIG. 4a. Each first link 321, each second link 324 and each third link 335 are provided with two stoppers 322, 325 and 336 separately. The stoppers 322, 325, 336 are used to restrict the movement of the links within a predetermined range.

[0039] Referring to FIG. 3b, before a PDP 40 is mounted on the wall, a case 41 is assembled on the backside of the PDP 40. The case 41 is provided with a plurality of bolts 42. There are four bolts 42 shown in FIG. 3b. The bolts 42 are used to engage the bolt holes 333 of the wall mount unit 30. FIG. 3c is a side view of the bolts 42. When the PDP 40 is combined with the wall mount unit 30, each bolt 42 is passed through the bigger portion of each bolt hole 333 first. Then, moving the PDP 40 downward so that each bolt 42 engages the smaller portion of each bolt hole 333, as shown in FIG. 3d.

[0040]FIGS. 4a, 4 b, 4 c, 4 d and FIG. 4e are side views of the first embodiment of the wall mount unit of the invention, wherein the mounted PDP is inclined at five, fifteen, twenty, twenty-three and twenty-five degrees respectively. Following that the first link 321 is located in different notches 332 of the guide slots 331, the inclined angle of the PDP 40 is adjusted.

[0041] Furthermore, according to different requirements, different inclined angles can be attained by changing the size of the guide slots.

[0042] Furthermore, the number of each part, such as notches and bolt holes, is not limited as long as it can attain the same effect as described above.

[0043] Furthermore, the wall mount unit 30 is provided with a plurality of openings to reduce the weight as long as the supporting strength is not affected.

[0044] In addition, constituting parts of each support are not restricted to the supporting stands. Each support can only consist of one supporting plate as long as it can attain the same characteristic.

[0045] Second embodiment

[0046]FIG. 5 is a side view of a second embodiment of a wall mount unit 60 of the invention. The wall mount unit 60 comprises a first support 61, a second support 62 and a third support 63. Some parts of the wall mount unit 60 are the same as the first embodiment; therefore, their descriptions are omitted.

[0047] The difference between this embodiment and the first embodiment is that in the second embodiment, guide slots 611 are formed on the first support 61.

[0048] An angle between the first support 61 and the third support 63 is adjusted by changing the position of a link 621 in the guide slots 611.

[0049] Third embodiment

[0050]FIG. 6 is a side view of a third embodiment of a wall mount unit 70 of the invention. The wall mount unit 70 comprises a first support 71, a second support 72 and a third support 73. Some parts of the wall mount unit 70 are the same as the first embodiment; therefore, their descriptions are omitted.

[0051] The differences between this embodiment and the first embodiment are that in the third embodiment, the second support 72 comprises third supporting stands 721 and fourth supporting stands 722. Also, guide slots 7221 are formed at each fourth supporting stand 722, and the third supporting stand 721 comprises a link 7211.

[0052] The numbers of third supporting stands 721 and fourth supporting stands 722 are one or more. An angle between the first support 71 and the third support 73 is adjusted by changing the position of the link 7211 in the guide slots 7221.

[0053] While the invention has been particularly shown and described with reference to a preferred embodiment, it will be readily appreciated by those of ordinary skill in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. It is intended that the claims be interpreted to cover the disclosed embodiment, those alternatives which have been discussed above, and all equivalents thereto.
