  • Publication number: 20060085107
    Abstract: A railroad, in particular an amusement ride, has a route subdivided into sections. Vehicles driven exclusively by gravity move along the route. Switching elements are arranged on the route for switches situated on the vehicles, in order to determine the position of the vehicles on the route. Vehicle controllers on the vehicles are connected to a central controller via a radio network. Brakes are arranged on the vehicles. Therefore, apart from the switching elements, all safety-relevant parts are shifted from the railroad to the vehicles and the vehicles are equipped with controllers, so that they can brake automatically and at any time if necessary, e.g. in the event of a failure or a disruption of the communication with the central controller.

  • Patent number: 6079238
    Abstract: A door mounting for a closure mechanism of a door (2), wherein the door mounting exhibits a locking means (11), which locking means (11) blocks a locking mechanism (29, 36) in a locking position, wherein the locking mechanism (20, 36) is mechanically coupled to the closure mechanism (2) and thus an actuation of the closure mechanism is not possible, if the locking means (11) is disposed in the locking position. The locking means (11) can be moved into an unlocked position with the aid of an adjustment mechanism (10, 50), wherein a support mechanism (15, 16) retains the locking means (11) in the region of the unlocked position and releases an actuation of the closure mechanism of the door (2).
