ABSTRACT:
A claw coupling for electric toy and model trains with prerelease has a claw, which can be hooked from the side into a rigid hook of the respective end supporting part, and which is spring-mounted and preclamped so that it can swivel in a horizontal plane into the coupling position and can be lifted upwardly by means of a coupling lever of a release track and which engages a pivot journal that projects downwardly. The pivot journal is mounted in a borehole acting against a vertical restoring force from its coupling position into a release position that is limited by a stop. The spring, which produces the restoring force that counteracts the swivelling motion, is in the form of a tongue adjacent to the claw, optionally with clearance, and is attached to a bearing part. A downwardly directed bearing leg, the length of which corresponds at least to the ejection height, is attached to the outerside of the claw, and the bearing leg is provided with an outwardly facing intercepting projection which, in the open position of the claw, underlies the tongue in such a manner that an accidental ejection due to vibrational shocks or the like is prevented. The upper side of the intercepting projection, facing the tongue, is formed as an inclined plane that slopes towards the outside.
