  • Publication number: 20050029424
    Abstract: An adjusting assembly for adjustably connecting a monitor (50) to a base (60), includes a first rotate assembly (10) connected with the base, a second rotate assembly (20) connected with the monitor, a support arm (30) connected with the first rotate assembly and the second rotate assembly, and a pair of transmission straps (80). The transmission straps alter the rotation of the first rotate assembly in one direction to the rotation of the second assembly in an opposite direction. The first rotate assembly generates a first torsional moment. The monitor generates a first gravity moment opposite to the first torsional moment. When the monitor rotates relative to the support arm, the first rotate assembly generates a second torsional moment to counteract a second gravity moment of the monitor relative to the support arm.

  • Patent number: 6781843
    Abstract: A computer enclosure includes a cage (10), an upper plate (100), two expansion bodies (140), and two operating devices (200). The cage has a chassis (12), a frame (16) received in the chassis, and an anti-EMI plate (18) attached onto the frame. Two recessed portions (102) are formed in the upper plate for accommodating the expansion bodies. The operating devices are attached to opposite sides of the chassis. Each operating device has a releasing device (202), a driving device (204), and a controlling device (206). When a button (258) of each controlling device is pressed inwardly and then pushed forwardly, a driving plate (254) of the controlling device drives the driving device to release the corresponding expansion body from the upper plate. When the buttons of the controlling devices are pressed inwardly and then pushed rearwardly, the driving plates drive the releasing devices to release the frame from the chassis.

  • Patent number: 6667880
    Abstract: A fixing apparatus (10) for storage devices (80) includes a drive bracket (20) and a fixing plate (40). The drive bracket includes a side panel (24) defining grooves (28) for slidingly receiving screws (82) that are attached on opposite sides of the storage devices. The fixing plate is attached on the side panel, and includes locking elements (44). Each locking element includes a spring portion (56), a stop wall (58), and a handle (60). To insert a storage device, the screws are slid along opposite grooves. One screw outward presses a spring portion, and causes it to be elastically deformed. When that screw has slid beyond the spring portion, the spring portion elastically returns to its original position. The stop wall and the side panel sandwich that screw therebetween. Up to three storage devices are thus secured within the drive bracket.
