Coupling for TT gauge model railway system has a plastic moulded clip with optimised guide and grip angles for a positive automatic coupling action

摘要

A coupling for a TT gauge model railway system has a plastic moulded clip with a guide arm (1) at approx. 20 deg. to the longditudinal axis and at approx. 50 deg. to an inner wedge shaped grip, with the adjacent inner angle (3) at approx. 150 deg. The outer pointed end of the coupling (5) has an angle of approx. 60 deg.
