Abstract: A track assembly includes a guide rail secured to a piece of furniture, a runner secured to a drawer and formed with end stops that run against stationary stops to limit the movement of the runner, an inner slide rail interconnecting the runner and the guide rail to one another to effect a linear travel of the runner relative to the guide rail. Positioned between the slide rail and the runner and the guide rail are cages for retaining balls therein. Each cage is provided in its end zones with supplemental elastic stops which cooperate with end stops so that stationary stops are first impacted by the elastic stops to align possibly tilted drawers before being impacted by the end stops.

Abstract: A track assembly for a drawer includes a guide rail securable to a piece of furniture, a pull-out rail securable to a drawer, and an inner section rail for connecting the guide rail with the pull-out rail. The guide and the pull-out rails are each formed of substantially L-shaped configuration and exhibit extreme edges that are turned inwardly to form three inner curved corner areas for receiving a set of three balls interposed between outer surfaces of the inner section rail and the inner surfaces of the guide rail and the pull-out rail and positioned such as to define corners of a rectangular triangle.

Abstract: An adjustment device aligns a drawer that is mounted on rails. A body member is fastened to the rail. An activation part is movably hinged to the body member at a hinge area. The activation part is connected to a wedge piece. The activation part is moveable to achieve alignment between the rail and the drawer. The body member, the activation part, and the wedge piece are integrally made of a plastic material. The hinge is formed by a material constriction in the form of a film hinge. The film hinge has an axis that is approximately parallel to a fastening plane disposed between the body member and the rail. The wedge piece extends approximately at right angles to the hinge axis and to the activation part.

Abstract: A device for holding a drawer closed includes a fork-like member which is pivotable between an inoperative position and an operative position. When the drawer is open, the fork-like member is normally in the inoperative position. As the drawer is closed, a pin on the drawer engages a first tine of the fork-like member to thereby pivot the latter to the operative position in which the pin is engaged by a second tine of the fork-like member. The second tine biases the pin under the action of a spring so as to hold the drawer closed. A returning member is integral with the fork-like member and serves to return the fork-like member to the inoperative position if the fork-like member is unintentionally pivoted to the operative position while the drawer is open. The returning member is provided with a channel having a first open end adjacent to the fork-like member and a second open end which faces the pin when the drawer is open and the fork-like member is in the operative position.
