Closure

摘要

In a closure for closing the orifice (13) of a neck (12), in particular the orifice of a fuel filler neck for automotive vehicles, a spring mechanism is provided which takes the form of a tightening device for drawing the closure part (14) automatically into its final closed position. The movement of the closure part (14) is controlled by a first guide slot (19). The operating lever (35), by means of which the closure part is moved, is furthermore hinged to the closure part (14) by means of a second guide slot (39), which, when an opening force is introduced via the closure part (14), blocks the movement of the closure part (14) from its closed position in the opening direction so that the closure part (14) cannot be manually opened from outside.

1. Closure for closing the orifice of a fuel filler neck for automotive vehicles, comprising:
a closure part that is movable, using a first guide slot, between a closed position in which the orifice of the neck is tightly closed and an open position in which the closure part is pivoted away from the orifice; at least one operating lever for movement of the closure part, which operating lever is mounted on the neck and hinged to the closure part; and a spring mechanism which takes the form of a tightening device for drawing the closure part automatically into its final closed position, wherein the operating lever is hinged to the closure part by a second, additional guide slot separated from the first guide slot, which, when an opening force is introduced via the closure part, blocks the movement of the closure part from its closed position in the opening direction.
