Abstract: Disclosed is a tile for covering roofs, produced in material with a polymer matrix (7) comprising a mineral charge (8) provided in a quantity ranging from 20% and 60% in weight, with respect to the total weight of the tile, the mineral charge being chosen from calcium carbonate, talc, barium sulphate, clay, and the tile having dimensions and thicknesses substantially identical to those of conventional tiles such as, selectively, Portuguese tiles, Marseilles tiles and curved tiles, and preferably being provided joined to similar tiles, in a way suitable to define a multiple tile.

Abstract: The device for stabilizing stacking up of tables (2) having folding legs (4) and a plate (3) provided with an edge (5), an upper face (6) and a lower face (7), comprises a latch element (12) movably connected to the plate (3) and a tooth (13) defining one end of the latch element (12). The latch element (12) is drivingly movable from a rest position to a work position at which the tooth (13) projects from the plate (3) to form a stop abutment preventing slipping with respect to an underlying table (2).

Abstract: A chair adapted to be stacked is provided, of the type having a rear frame (2) including two rear uprights (3) and rear crosspieces (5), a front frame (7) including two front uprights (8) and front crosspieces (9), a seat (10) and lateral crossbars (11) connecting the rear uprights (3) with the front uprights (8), the chair further having shaped close-fit regions (13) formed in at least one of the frames (2, 7) to removably engage, by close fitting, an underlying chair in a stacked position and the engagement taking place by forced and elastic deformation of the frames (2, 7) at the shaped close-fit regions (13).

Abstract: There is provided a support device comprising shaped bodies (5) suitable for engagement with bottom ends (2a, 3a) of chairs (1), each of which has a coupling axis (6), a coupling cavity (7) extending along the coupling axis (6) and insertable on said bottom ends (2a, 3a) by pressure and in a removable manner, and a support face (8) expanded in a direction radial to the coupling axis (6), which face can be directly put in contact with the ground and rest thereon and which is provided with openings (10) to break the continuity of the ground-contact surface, and indentations (11) to avoid interferences when the chairs are stacked up.

Abstract: There is disclosed a device (1) for stabilizing stacking up of tables (2) having folding legs (4) and a plate (3) provided with an edge (5), an upper face (6) and a lower face (7), the device (1) comprising: one latch-like element (12) movably connected to the plate (3) and one tooth (13) defining one end of said latch-like element (12), the latter being drivingly movable from a rest position to a work position at which the tooth (13) projects from the plate (3) to form a stop abutment preventing slipping with respect to an underlying plate (3′).

Abstract: A chair adapted to be stacked is provided, of the type having a rear frame (2) including two rear uprights (3) and rear crosspieces (5), a front frame (7) including two front uprights (8) and front crosspieces (9), a seat (10) and lateral crossbars (11) connecting the rear uprights (3) with the front uprights (8), the chair further having shaped close-fit regions (13) formed in at least one of the frames (2, 7) to removably engage, by close fitting, an underlying chair in a stacked position and the engagement taking place by forced and elastic deformation of the frames (2, 7) at the shaped close-fit regions (13).

Abstract: An improved folding chair is provided, which comprises two uprights (2) each having an intermediate section (10), two struts (6) articulated on the uprights (2) and each having two ends (15a, 15b) defining a lower length than that of the uprights (2) and similar to that of the intermediate section (10), and a seat (9) articulated on the struts (6) and the uprights (2) and movable therewith between a use position, in which the uprights (2) and struts (6) are transverse to each other and define four supports resting on the ground, and a compacted position in which each strut (6) is disposed alongside an intermediate section (10) of an upright (2), each upright (2) being provided with shaped portions (14a, 14b) jutting out from opposite sides of the intermediate section (10) and forming stop abutments for the ends (15a, 15b) of a strut (6) of an adjacent folding chair.
