  5. An apparatus for smoothing slabs of concrete and other aggregates according to claims 1 and 4, characterised in that the telescopic arms (3-3') comprised of a female tube (27) and a male tube (30), the height and rotation of which can be adjusted by means of an eccentric lock (31) integral with the female tube (27), are provided with articulated handles.
  6. An apparatus for smoothing slabs of concrete and other aggregates according to claims 1, 4 and 5 characterised in that the upper end of the male tube (30) is provided with an articulated handle (32) that can be adjusted by means of two toothed discs (33-34), toothed disc (33) integral with the male tube (30) and toothed disc (34) integral with the articulated handle (32), a screw (36) concentric to the two toothed discs (33-34) going through the assembly, which is locked by means of a nut (37) integral with the male tube (30) of the telescopic arms (3-3') after the desired position of the articulated handle (32) is adjusted and after the toothing of the toothed disc (33) is engaged fully with the toothing of toothed disc (34) so as to eliminate any play.
  7. An apparatus for smoothing slabs of concrete and other aggregates according to claim 1 characterised in that the articulated part (20) of the removable articulated device (2) is provided with a storage tube (35) designed to act as storage for the two telescopic arms (3-3') taken out of the sleeves (25-25') and provided with a spring pusher (28) that clicks into the holes (38-38') provided for that purpose on the storage tube (35), or as a housing for a weight to make the apparatus heavier if required.
