DETAILED DESCRIPTION
Referring to FIGS. 1-3, a display device 10 includes a seat 100, a support member 200, a display panel 300, and an adjusting member 400.
The support member 200 may be generally cylindrical. One end of the support member 200 is attached to the seat 100. A first through hole 202 is defined at another end of the support member 200 and is used in attaching the support member 200 to the adjusting member 400. The hole 202 is formed with its axis generally perpendicular to the axis of the support member 200.
The adjusting member 400 includes a pair of first linkage poles 402, a pair of second linkage poles 404, a pair of third linkage poles 406, a fixing member 408, a first rotating shaft 432, a second rotating shaft 434, a third rotating shaft 436, and a fourth rotating shaft 438.
A second through hole 450A is defined at one end of each of the first linkage poles 402, and a third through hole 450B is defined at another end of each of the first linkage poles 402. A first blind hole 470A is defined at one end of each of the second linkage poles 404, and a second blind hole 470B is defined at another end of each of the second linkage poles 404. A third blind hole 490A is defined at one end of each of the third linkage poles 406, and a fourth blind hole 490B is defined at another end of each of the third linkage poles 406.
The fixing member 408 includes a thin base portion 480. The base portion 480 includes a first projection portion 482 and a second projection portion 484 formed thereon. The projection portions 482 and 484 are spaced from each other. A fourth through hole 492 and a fifth through hole 494 are formed along the width of the projection portions 482 and 484, and are formed with their axes generally parallel to the base portion 480. In the embodiment as shown in FIG. 3, the base portion 480 is generally rectangular and can be movably attached to the rear of the panel 300.
The third rotating shaft 436 passes through the fourth through hole 492, and the fourth rotating shaft 438 passes through the fifth through hole 494. The second linkage poles 404 are pivotably attached to the third rotating shaft 436 by placing the third blind holes 470B over the two opposite ends of the third rotating shaft 436. Similarly, the third linkage poles 406 are pivotably attached to the fourth rotating shaft 438 by placing the fourth blind holes 490B over the two opposite ends of the fourth rotating shaft 438. The first rotating shaft 432 passes through the first through hole 202. The first linkage poles 402 are pivotably attached to the first rotating shaft 432 by placing the second through holes 450A over the first rotating shaft 432, and the second through holes 450A located adjacent to two opposite sidewalls of the support member 200. The first linkage poles 402 are pivotably attached to the second rotating shaft 434 by placing the third through holes 450B over the second rotating shaft 434. The third linkage poles 406 are pivotably attached to the first rotating shaft 432 by placing the third blind holes 490A over the two opposite ends of the first rotating shaft 432. Similarly, the second linkage poles 404 are pivotably attached to the second rotating shaft 434. After assembling, the fixing member 408, the first linkage poles 402, the second linkage poles 404, the third linkage poles 406, and the fixing member 408 form a transmutable quadrilateral.
Referring to FIG. 4, a rail 302 is formed on the rear side of the panel 300. The rail 302 includes a receiving space 304. The base portion 480 can be received in the receiving space 304 and can be moved along the rail 302. The fixing member 408 is thus moveably attached to the rear of the panel 300 via the sliding engagement of the base portion 480 and the rail 302.
After assembly, the panel 300 is moveably attached to the adjusting member 400 and the adjusting member 400 is pivotably attached to the support member 200. Because the adjusting member 400 is pivotably attached to the support member 200, the panel 300 can be rotated to a desired angle. Because the panel 300 is movably attached to the adjusting member 400, after the panel 300 is adjusted to the desired angle, users can further adjust the height of the panel 300 by moving the panel 300 up or down.
Although the present disclosure has been specifically described on the basis of the embodiments thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiments without departing from the scope and spirit of the disclosure.
