Gravity conveyor roller

Abstract

A gravity-convyor roller with two longitudinal spars (1) extending mutually parallel, in which a plurality of rollers (2) are held rotatably and which are connected to one another via connecting parts. In order to allow a simple connection of the longitudinal spars it is provided that the longitudinal spars (1) are formed by substantially C-shaped profiles whose straps (5) are located at the outside and whose upper legs (4) have recesses (8) which are open towards vertically downwardly facing bend-offs (6) extending parallel to the straps (5), the recesses (8) extend over a part of the height of the bend-offs (6) and having an inner width smaller in the zone of the bend-offs (6) than their largest inner width extending parallel to the strap (5), the said connecting parts (3) are provided with noses (9) arranged on their face sides engaging in the said recesses (8) arranged in transversal planes extending perpendicularly to the longitudinal spars (1), the cross sections of the said, noses (9) correspond to the recesses (8) in the zone of the legs (4), and the noses (9) having at least one slot (1) extending preferably transversally to the longitudinal spars (1) and having central bores (10) in which clamping screws (15) may be inserted to widen the said slots (14).
