Chain guide for multiple chains moving in longitudinal direction, particularly for one or multiple drives or safety chains of lifting door, has base body, which has chain guide surface for chains

摘要

The chain guide has a base body, which has a chain guide surface for the chains (3,4). The base body has a slot-shaped chain receiving opening for multiple parallel running chains. The chain receiving opening is bounded by two chain guide surfaces per chain. The base body is made from plastic, particularly Polyethylene. An independent claim is also included for a door frame with a door frame.
