  • Publication number: 20160167098
    Abstract: A manufacturing method and structure of hidden slide's slide unit, which the slide unit sets between upper and lower rail bars. The slide unit is made by long-plate-shaped substrate, which has the following steps: preliminary forming, pressure bending and rolling forming. First, preliminary forming and pressure bending can make substrate a prototype, then rolling forming can make substrate become a slide unit and the slide unit can be squeezed and concentrated. Therefore, the density of the slide unit structure is increased to enhance the strength of structure, which can avoid the slide be deformed, insure the operation quality of hidden slide can slide out smoothly, increase service life, decrease manufacturing cost, and have better economic benefit.

  • Patent number: 8491068
    Abstract: A drawer assembly includes a housing, a drawer body retractably mounted on the housing, two locking members mounted in the housing, and a control bar pivotally mounted on the drawer body and having two opposite ends each provided with a locking end that is movable to lock a respective one of the locking members. Thus, when the drawer body is retracted into and received in the housing, the locking end of the control bar is locked onto the respective locking member to lock the drawer body onto the housing so that the drawer body is locked onto the housing when the drawer assembly is closed and will not be moved outward from the housing when the drawer assembly is moved or declined to facilitate the user moving or transporting the drawer assembly.

  • Patent number: 6672692
    Abstract: Automatically restoring device for slide rail assembly, including a fixed unit, a horizontally slidable receptacle and an automatically restoring section. The fixed unit includes a pair of fixed rails. The horizontally slidable receptacle includes a pair of movable rails. The automatically restoring section is disposed at one end of the fixed rail. One end of each movable rail is formed with a push section. The automatically restoring section includes two slide way bodies, a deflection body and a resilient body. When the push section of the movable rail inward pushes the deflection body, the deflection body is deflected by an angle to engage with and drive the movable rail so as to automatically restore the movable rail to its home position and lock the movable rail therein.

  • Publication number: 20020089273
    Abstract: Guide structure for telescopic rail assembly, including an outer slide rail, an inner slide rail, a protective section, a pair of first slopes, a pair of second slopes and a pair of third slopes. The outer slide rail is disposed on a cabinet body, while the inner slide rail is disposed on a drawer and slidably nested in the outer slide rail. A ball bearing is disposed between the outer and inner slide rails to facilitate sliding thereof. The protective section is formed with the first and second slopes and positioned between front end of the ball bearing and front end of the outer slide rail. Rear end of the inner slide rail is formed with the third slopes. After the drawer is drawn out of the cabinet body, by means of the first, second and third slopes, the inner slide rail can be easily nested into the outer slide rail without colliding the ball bearing, whereby the ball bearing will not jump away or damage.

  • Patent number: 6378968
    Abstract: Sliding track assembly, including an outer slide rail, a middle slide rail, an inner slide rail and at least one transmission section disposed on the middle slide rail. The outer slide rail is disposed on a cabinet. The middle slide rail is slidably positioned in the outer slide rail. The inner slide rail is disposed on a drawer and slidably positioned in the middle slide rail. The transmission section is disposed with at least one stop section and transmission member disposed at the stop section. The stop section is disposed at predetermined portion of the middle slide rail, whereby the transmission member can respectively contact with predetermined portions of the outer slide rail and inner slide rail. When the inner slide rail slides, the transmission member simultaneously drives the stop section of the middle slide rail. Therefore, the middle and the outer slide rails and the middle and inner slide rails are synchronously slid relative to each other.
