Abstract:
1. 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 ( 15 A) and bottom surface ( 15 ) and a plurality of module link ends ( 4 ) projecting from said front and rear walls, 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 releasably 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 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 said second portion ( 8 ) of the pin ( 6 ) 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 ), characterised in that said seat ( 10 ) and said pin ( 6 ) comprises means ( 11 A, 11 B) 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, said parts ( 14 , 16 ) being provided near one of said lateral walls ( 17 ).
