  • Patent number: 6798646
    Abstract: A rotary axle structure for portable computers mainly includes a member with an indented notch formed on the surface thereof and a sloped element with an elevation higher than the surface of the indented notch. The display device of a portable computer has a pivotal shalt located on the surface of the member. When the display device is lifted and turned about the first axis, the pivotal shaft may be lowered in the indented notch or be lifted to the sloped element to alter the distance between a leaning element in the first axis and the main body so that the display device may be lifted and moved away from the main body. Thus the display device may be swiveled without scraping the computer main body or the bottom of the display device.
