When the stop device is in its operating position, the flap (3) is rotated, by the pressing of the nose (4), against the force component of the spiral spring out of the elevated plane level until the neck (9) of the flap (3) is supported on the surface (8) of the approach profile (2). In this process, the force component of the spiral spring (5) which is mounted on one side in a channel (10) of the approach profile (2) and on the other side in the channel (11) of the flap (3) ensures that the flap (3) remains in its operating position. The flap (3) and the nose (4) together form a rocker which is held in the "operating" or "out of operation" positions respectively by specific guiding of the force component of the spiral spring (5). This stop device structure, which is essentially composed of extruded profile sections, provides both a simple stop device which saves costs, as well as operating in a simple manner. The additional expenditure needed to ensure greater safety is therefore kept low. <IMAGE> |
