摘要： A device for opening and closing a hatchway on a combat vehicle, especially a tank, by a hatch. The hatch comprises two components, one above the other. The upper component slides back and forth across and above the hatchway. The lower component descends tight into the hatchway. The object is to simplify the generic device to the extent that it can be operated from inside the vehicle. An operations-control rack extends along the upper component in the direction it slides back and forth in. The rack is engaged by a pinion. The pinion is part of a mechanism mounted on the vehicle and controlled from inside the vehicle. A cam track is fastened tight to the rack. A control pin rests against the cam track. The cam track operates by way of the control pin in conjunction with at least one mechanism that locks the upper component in position. The upper component is attached to the rack by a clutch. The clutch ensures that the rack will advance to a certain extent during the first stage of opening the hatchway before it engages the upper component. The control pin disengages at least one of the mechanisms that locks the upper component into position with the hatchway closed while the rack is still unengaged.
