The invention relates to filing cabinets for suspended plans. The means for the compensated guidance and graduated opening of the door (2) comprise at least one guide arm (3) carrying, at its free end, at least one roller (30, 31) sliding in a slide track (4) fastened to the frame (1) of the cabinet. Each arm is supported, at the entrance of the slide track, by at least one roller (15) pivoting on a journal (15') fastened to the frame. The guide arm is equipped with a movable stop (6) having a spring stud (7) and pivoting on a journal (5) and with a fixed stop (9). A plate (10) fastened to the frame retains the guide arm in the slide track; this plate has means for the graduated opening of the door which comprises an ejector (12) pivoting on a journal (11), a stop (13) and a reactivating finger (14).
A self-retaining rack slide for rack-mounted computer systems. The rack slide includes a slide and a rack mounting member which are fastened together while permitting relative longitudinal movement between the two parts. A biasing mechanism such as a spring is fastened to the mounting member and the slide to urge the two lengthwise apart to increase the length of the slide rack. A complementary slide fastened to a rack component slidingly engages the rack slide to permit the component to be slid into and out of the rack.
The invention concerns a drawer slide assembly, preferably for use in appliances, comprising a catch mechanism for resisting slide extension when the drawer is in a closed position. The catch mechanism is made of a spring arm pivotally mounted to one of the rails and an anchorage point provided in the other rail. When the assembly is moved to the closed position, the anchorage point engages and rotates the spring arm about its axis. Thus, opening the drawer requires a certain force to rotate the spring back. The use of a simple spring arm reduces friction between parts, reduces assembly costs and maintains desired flexibility and tolerance for drawer production and usage.
