Abstract
The invention relates to a support device for a rigid chain (401) composed of links (402) that are connected in pairs by rollers (403). The movement of the rigid chain is guided by an internal housing (406) of a support casing (405). One or more support pins (404) project from one side of the chain, parallel to the axis of the link rollers. Furthermore, a face (411) of the casing extending substantially perpendicularly to the axes of the rollers has a through-groove (412) communicating with the internal housing (406). This groove (412) extends along the entire length of the housing and has dimensions, in a plane perpendicular to the axes of the rollers (403), that are sufficient to allow through only the support pin(s) (404), which pass through the groove (412) and protrude from the support casing (405) by a predetermined length allowing the fastening of one or more functional elements.
