Claims

1. Guard for use with a conveyor structure where the conveyor structure comprises a number of articulately jointed conveying elements such that the conveying elements provide a conveying plane for conveying objects, where each conveying element has at least one free end extending away from the articulate joint, and where a guard is provided between the extremities of the free ends of the conveying elements.

2. Guard according to claim 1, wherein the conveying elements are rollers, and that the guard is fastened between non-rotating parts of each roller.

3. Guard according to claim 1, wherein the conveying elements are box elements in which box elements in an upper part conveying means are arranged, and that the guard is arranged between outer edges of adjacent boxes.

4. Guard according to claim 1, wherein the conveying elements may extend on either side of the articulated joint, and that guards are provided on both extremities of each conveying element.
