Abstract

In a trap door chute for vending machines, doors are pivotably mounted to sidewalls of the machine, in a certain trap door chute division. Each door supports itself in its merchandise storing position by a finger on an electric detention member. Along one chute wall extends at least one vertical track, along which a carriage with a cam for the deflection of the detention member is movably guided. A lifting bar extends parallel to the track and has a row of teeth whose spacing corresponds to the smallest trap door chute division. The carriage supports itself on the row of teeth via a stepping pawl. A stop is provided on the carriage, with which it rests on one of the detention members. The detention members are tines of a rake made of a spring material.
