Abstract: A furniture system including at least one worktop which mounts thereon a plurality of legs adjustable in height. The legs are connected to respective support plates recessed in the underside of the worktop. At least one linear guide is recessed into the underside of the worktop for the mounting of accessories on the worktop. A plurality of worktops can be mounted in spaced relation from a support surface by a common leg via support arms. The worktops can be joined together in either a flush arrangement or separated from one another. In the separated configuration, a tray can be fitted in the space between two adjacent worktops for the housing of cables, electrical sockets and the like.

Abstract: The modular furniture system, particularly for offices, comprises at least one column-like upright element having a vertically elongate body and a plurality of fixtures which can be coupled selectively to the two ends and to the body of the upright to form a furniture arrangement. The vertical positions of the fixtures coupled to the body of tile upright can be adjusted continuously to achieve different heights for components such as work surfaces, shelves, suspended units, screens, lighting equipment and the like. The upright is self-supporting and permits multiple connection of fixtures which are independent of one another.

Abstract: A modular unit for assembling seats comprises a plurality of elements which are spatially complementary and can be grouped together about an axis. The elements can be associated with respective portions of the seat to be produced and are rigidly connected together by a screw which can extend through a longitudinal hole formed jointly by grooves in the elements. The rotation of the screw causes a transverse sliding of two locking elements having inclined surfaces which cooperate with respective sloped portions of the elements in order to urge the elements into a state in which they are assembled about the axis. The elements may be of integral construction with portions of the seat such as a seat portion, an armrest portion or a leg portion.

Abstract: A smoothing machine for wood panels, particularly wood panels having contoured surfaces with parts in relief, includes a substantially horizontal conveyor belt, a support structure overlying the belt, and a plurality of smoothing units carried by the structure. Each smoothing unit comprises a support frame and an abrasive roller rotatably supported by the frame and driven by a motor mounted on the frame, the rollers facing the belt and having coplanar horizontal axes of rotation. In the machine, each of the frames is pivoted about a vertical pivot axis on a motor-driven rotor rotatably supported about a vertical axis of rotation by the support structure, and the frames are releasably fixed to the rotor. The machine enables multi-directional smoothing whereby it is possible to smooth even very irregular panels.

Abstract: A chair is described which comprises a fixed base structure, a seat, an element moveable relative to the fixed structure of the chair, the moveable element being moveable from a first operative position to a second operative position as a result of a thrust exerted by the body of a seated person, and resilient means biasing the moveable element towards its first operative position. The seat of the chair has at least one part moveable substantially vertically (the movement of the moveable element being distinct from the substantially vertical movement of the moveable part of the seat). The chair also includes a resilient member for returning the moveable part of the seat to a raised position for sensing the weight of the seated person, and for adjusting automatically the load of the resilient member in dependence on the weight of the seated person.

Abstract: A chair has a reclinable backrest formed by a series of at least three superimposed segments articulated together about respective substantially horizontal axes to define, in the reclined position of the backrest, an arcuate configuration with a curve substantially corresponding to that of the arched back of a user. Resilient means are provided for resisting the movement of the segments towards the position corresponding to the reclined position of the backrest.

Abstract: A column and a plurality of support members having radially extending arm and/or foot portions, having an inner end portion shaped as a sector of a cylinder with an axial Morse tapered hole, and adapted to be received in the inside of the hollow end portion of the column. A bolt is screwed in an axial threaded hole of a Morse tapered body made of metal, and with its head resting on the upper ends of said sector-like portions of the arm or foot members or on the lower ends of the sector-like portions of the foot members. The body is presented from rotary movement with respect to the arm or foot members and is permitted mutual axial movement with respect thereto to pressure the supports against the column.

Abstract: An arm support member for chairs or seats provided with an arm rest frame connected to said arm support member by a hinge mechanism. The arm rest frame is swung under the effect of a first spring into a vertical position, by a rotation about a horizontal axis parallel to and spaced apart from the longitudinal center plane (A-A) of the arm support member. The hinge mechanism also enables the arm rest frame to perform a sliding movement parallely to the hinge axis against the effect of a second spring only when the frame is in its raised position. Locking means is provided to hold the arm rest in both positions.

Abstract: Modular elements for composing disassemblable walls, cabinets, writing tables and other pieces of furniture comprising:panels;box-like metal sections provided on three surfaces thereof with a groove defining a longitudinal slot of a width lower than that of the groove while from the remaining surface, anchoring means extend outwardly to connect each section to a panel;column devices having, at its ends, pieces to be received inside the central grooves of said sections and cooperating with means for locking said pieces in its engaged position, said column housing a hollow tubular pivot member, into which passes a threaded rod having a upper control head and which at its lower end rests on an adjustable ground engaging foot;cylindrical rods for the connection of wall panels, in coplanar relationship;expansion screws to be inserted into the front grooves of the sections for carrying hooks, and the like;hinge devices for the connection of adjacent wall panels at right angles and to allow said panels to be fold on

Abstract: A table comprising a vertical column provided at the upper end with a plurality of radially outwardly directed arm members for supporting the table top and at the lower end with radially outwardly directed foot members detachably connected thereto said arm and foot members having their inner cylinder sector-like portions at least the end portions of the column being hollow and the inner sector-like elements of the arm and foot members are dimensioned to form together respectively at least a part of a hollow cylindrical body adapted to be received at least partially inside one of said hollow end portions of the column respectively, sector-like members of different angular amplitudes being provided to be arranged between said inner sector-like elements of the arm members and foot members respectively, which fill the space therebetween when necessary, an expansion locking device being coaxially mounted inside the hole defined in combination by said sector-like elements adapted to apply a radial pressure on said
