摘要:
A shelving, particularly for use as bookshelves, comprises a support structure (16; 19, 20; 27; 34) and a series of horizontal shelves (1) carried by the support structure. Each horizontal shelf (1) comprises a series of flat telescopic elements located side by side, so that it can assume any length between a minimum length and a maximum length.

An extensible table is described which comprises a rigid panel (4) defining the working plane of the table in a condition of minimum extension thereof and at least one structure (9) for extending the panel including a frame (10) connected to the panel (4) so as to be slidable in a direction parallel to the plane of the panel (4) and movable between an extreme retracted position within the panel (4) and an extreme extended position in which the frame (10) projects from one side of the panel (4). The table further includes a flexible covering sheet (16) fixed to the panel (4) and having a part projecting from the panel and extending in the direction of sliding of the said frame (10), and guide means (23) for the flexible sheet carried by the said frame (10) and engaged by the flexible sheet (16) so that the latter has a first pass arranged to constitute an elongation of the working plane and a second pass guided beneath the first pass; the lengths of the first and second passes being a minimum and a maximum respectively in the completely retracted position of the frame (4) and a maximum and a minimum respectively in the completely extended position of the frame. In a preferred embodiment, two structures (9) for lengthening the rigid panel (4) are provided which project from two opposite sides of the latter. A respective pair of table legs (2) is connected to the frame of each lengthening structure. By virtue of this structure the table is able to take up any configuration intermediate the minimum and maximum conditions of length.
摘要:
A ladder comprises a pair of main stiles (1), a series of centrally-hinged rungs (5) with ends (7, 8) articulated to the two main stiles (1), whereby the ladder can adopt a folded inoperative configuration in which the main stiles (1) are alongside each other and an extended operative configuration in which the main stiles (1) are spaced from each other, and means for stopping the ladder in the extended operative configuration. The main stiles (1) are articulated together at their upper ends and the ladder further includes a single auxiliary stile (3) articulated at its upper end to the two upper ends of the main stiles (1) about an axis (4) substantially perpendicular to the articulation axis (2) of the two main stiles (1). The auxiliary stile (3) is movable between a position alongside the two main stiles (1), corresponding to the folded inoperative condition of the ladder, and a position spaced from the main stiles (1), corresponding to the extended operative condition of the ladder.
