    Abstract: A monitor support structure generally comprises a clamping unit, a rotatable arm, a support arm, a pivotal connecting unit, a linking rod, and a shiftable unit. The clamping unit is provided for fixing so as to allow the monitor support structure to hold and support an article. The pivotal connecting unit allows the support arm to shift upward or downward for adjusting the tilt angle of the article. Besides, the elastic devices provide the elastic force for pulling the support arm downward so as to share the weight of the article. Moreover, the linking rod can balance the weight of the article for steadily supporting the article.

  • Patent number: 7320452
    Abstract: An adjustable rail-hanging apparatus comprises a main body and a limit device, wherein a hooking part for hooking an aluminum extrusion hanging board is mounted on the upper end of the main body. First screw holes to be inserted by first locking devices are formed on both sides of the main body and guiding grooves are oppositely formed on both sides of the lower end of the main body respectively for movably holding the limit device. A hooking notch is formed on each holding part of the limit device. The adjustable limit device is movably shifted up and down by disposing second locking devices in the guiding grooves and holding the aluminum extrusion hanging board by the hooking notch and the hooking part on the upper end of the main body cooperatively. Consequently, the movable limit device is suitable for aluminum extrusion hanging board with various rail gauges.

  • Publication number: 20070205345
    Abstract: An adjusting structure is located between a bracing frame and a monitor for height adjustment by using slide-type mechanisms. The adjusting structure comprises a fixing base, a slide base, and a slide means, wherein several trenches are formed on the fixing base for holding the bracing frame. Two insertion trenches are oppositely formed on both sides of the fixing base for holding the slide base. The slide means is coupled with the monitor. When the user holds the both sides of the monitor, he can exactly hook and hold a braking shaft by hands so as to release ratches from a stop device such that the slide means, which is coupled with the monitor, can be inserted into the slide base so as to engage the ratches with the racks. As a result, the adjusting structure can be rapidly, accurately, and finely shifted to a proper height.

  • Publication number: 20070012841
    Abstract: A bi-axial keyboard bracket is disclosed. The bi-axial keyboard bracket comprises: a slideable plate; a set of X-axis slideways; and a set of Y-axis slideways. The X-axis slideways are horizontally spaced out in a predetermined distance. Each X-axis slideway comprises: a fixed track having a trench; a shorter movable track mounted in the trench; and a connection plate movably embedded in the movable track. The Y-axis slideways are horizontally located between the X-axis slideways. Each Y-axis slideway comprises: a fixed track having a trench; a shorter movable track mounted in the trench; and a connection plate movably embedded in the movable track for connecting the slideable plate with the Y-axis slideways. Accordingly, the keyboard bracket can be pulled out or pushed back by shifting the slideable plate along the Y-axis slideways and the keyboard bracket can be shifted leftward or rightward by shifting the slideable plate along the X-axis slideways.

  • Publication number: 20060207208
    Abstract: A bracing frame to be clipped to a cantilever comprises a spool and a fixing rest, wherein the spool consists of a bar-shaped spindle and a plurality of bar-shaped raised tracks. The raised tracks surround the periphery surface of the spindle. A gap is formed between every two adjacent raised tracks. An inward contracted connection part having narrower width is formed between every raised track and the spindle for improving the clipping effect, and a notch is formed respectively on both sides of the connection part. The bracing frame is connected to a clip and a cantilever for holding articles. One or more clips can be disposed side by side or crisscross in any direction. The clips can clip to the raised track at different heights thereby achieving the optimum practicability and efficacy.

    Abstract: A land grid array connector (1) for electrically connecting a CPU package (3) to a printed circuit board includes a housing (2) and a number of contacts received in passageways (284) of the housing. The housing has a bottom wall (28) and sidewalls (22,24,26). The bottom wall and the sidewalls cooperatively define a receiving space (20) for accommodating the package therein. Protrusion member (228) is formed on the sidewalls and extends inwardly into the receiving space. A through hole (280) below the protrusion member is defined in the bottom wall for facilitating molding the protrusion member. The protrusion member is configured with a vertical abutting surface (2280) formed at a lateral end toward the receiving space thereof. The bottom wall forms a mounting surface (2820) for sustaining the CPU chip thereon. A vertical shortest distance is formed between a lowest end of the abutting surface of the protrusion member and the mounting surface of the bottom wall.
