The invention relates to a conveyor chain, which comprises chain links (1) consisting of a barrel portion (2) and elongated side bars (3,4), the first ends of which are attached to the ends of the barrel, whereby the distance between the free ends of the side bars (3,4) corresponds to the length of the barrel (2) including the side bars attached to it. In order to enable the assembly of a chain of identical, mutually similar parts without tools, the surfaces located opposite each other at the free ends of the bars (3,4) of the chain links are provided with studs (5,6), the outer diameter of which corresponds to the inner diameter of the barrel (2) and the elasticity of the bar (3,4) material is such that the bars can be spread from each other to such an extent as to enable the insertion of the studs (5,6) of one chain link into the barrel (2) of another chain link.

A conveyor chain comprising a plurality of adjacent chain links, each chain link including: a barrel portion including an inside cylindrical surface having an inside diameter, and first and second spaced apart shoulders extending radially inward from said inside surface; first and second generally parallel, elongated side arms, each side arm having a first end connected to and extending away from the barrel portion; a first cylindrical stud extending inward from a second end of the first side arm, having an outside diameter approximately equal to the inside diameter of the barrel portion, and including (i) a first circumferential recess extending radially inward from an outside surface of the first stud, to receive and hold the first shoulder of the barrel portion of an adjacent chain link, and (ii) a first axial groove extending inward from the outside surface of the first stud, and extending away from the first circumferential recess along the axis of the first stud, to facilitate sliding the first shoulder of the barrel portion of the adjacent chain link into the first circumferential recess; a second cylindrical stud extending inward from a second end of the second side arm, having an outside diameter approximately equal to the inside diameter of the barrel portion, and including, (i) a second circumferential recess extending radially inward from an outside surface of the second stud, to receive and to hold the second shoulder of the barrel portion of the adjacent chain link, and (ii) a second axial groove extending inward from the outside surface of the second stud, and extending away from the second circumferential recess along the axis of the second stud, to facilitate sliding the second shoulder of the barrel of the adjacent chain link into the second circumferential recess.
