Abstract

A conveyor comprising a plurality of modules (1) arranged one after the other, each of said modules comprising two parallel front and rear walls (2,3), two parallel lateral walls (17) and a top and bottom surface (15) and projecting from said front and rear wall a plurality of module link ends (4), the module ends (4) of one module intermeshing with the module ends of the previous and successive modules, said module ends (4) including coaxially aligned openings (5) adapted to receive a transverse pin (6) for realisably joining said modules, said pin (6) comprising a first cylindrically shaped portion (7) extending in said openings (5) and a second portion (8), radially departing from one end of said first portion, said pin being rotatable, about a longitudinal axis (L) of said first portion (7) of the pin (6), between a first position (F) not restricting the axial movement of said pin (6) in said openings (5) and a second position (R) restricting said axial movement, a lateral portion (9) of each of said modules (1) comprising a seat (10) for housing and for restricting axial movement of said second portion (8) of the pin (6) when the pin is rotated in said second position (R), said seat (10) comprising a passage (13) for introducing in said seat at least a part of said second portion (8) of the pin (6), wherein said seat (10) and said pin (6) comprise means (11A, 11B) for releasably preventing the displacement of said second portion (8) of the pin (6) from said second position (R), in that said seat (10) is provided in a lateral bottom portion (9) of the module (1), and in that said passage (13) extends from a part (14) of the bottom surface (15) of the module (1) to a part (16) of one of said walls (2, 3), from which said link ends (4) project, provided near one of said lateral walls (17).
