Abstract:
The invention is an apparatus for moving a cover of an article of furniture in which a lift device is installed. The cover overlies an object to be raised by the lift device. The lift device includes a movable frame for raising and lowering the object. The apparatus includes a retracting mechanism, a cam mechanism, and a reverse motion mechanism. The retracting mechanism is coupled to a rear edge of the cover by a hinge means and includes at least one guide structured and arranged to guide the hinge means in a vertical plane. The cam mechanism includes at least one cam member fixed to the movable frame of the lift unit. The reverse motion mechanism includes a driver fixed to the movable frame of the lift device. The driver is operatively coupled to the retracting mechanism.
Abstract:
The lift has dual-screw lifting assembly (A) installed inside the three-modular telescopic column (B). Lifting assembly (A) has spindle drive screw (1) coupled via gear (6) with electric motor (5) and threaded part driven into sleeve screw (2), and its external thread engages with nut of actuator (9) of telescopic column (B). Actuator (9) and embracing it central module (8), are run coaxially and along the fixed external module (7). Bracket (C) of lifted object (20) is fitted to actuator (9). The cross-section of the wall of external (7) and central (8) module is in the shape of regular polygonal geometric figures, similar to each other and actuator (9) is similar to them in shape or is round. Module guides (7, 8, 9) are made up of linear double-row, ball bearings (10), mounted on axes of symmetry of cross-sections and accordingly with external (11) raceway and internal (12) raceway rail to the neighboring wall surfaces.
