摘要： A lock for a rolling grille effective for barring a closure is concealed in the grille guide structure and actuates upon attempts to unbar the closure by applying opening forces to the grille. The opening forces serve to pivot lock-links laterally of the grille into engagement with a lock abuttment in the grille guide structure. In the normal operating mode of the grille, the lock-links are disposed in a retracted condition.

摘要： Articulated grille has identical links arranged in pairs as end links and intermediate links. Spoollike connectors loosely unite ends of intermediate links and hatlike connectors unite the end links and receive horizontal link-connecting rods loosely therethrough. Link-positioning rods extend through medial holes in the links and hat-shaped end keepers and retaining ring keepers positioning rods maintain the grille assembly.

摘要： A rolling door curtain may be raised or lowered by a driving mechanism including a motor driven gearbox which is selectively coupled by an electro-mechanical clutch and a manual operating mechanism. A safety brake coupled between the clutch and manual operator prevents driving of the manual operator by the motor should the clutch fail to disengage and functions as a stopping brake whenever the motor is stopped.

摘要： A clutch for a rolling door operating mechanism safeguards a door counterbalance mechanism by actuating a rotatable brake member against a stationary drum should the counterbalance fail. The brake is released again by normally driving the operating mechanism. In one form, the clutch is arranged on a stationary shaft coaxially with the driving input; in a second form the clutch is on the rotatable shaft of the door barrel.
摘要翻译： 如果平衡失败，则用于滚动门操作机构的离合器通过致动可旋转的制动构件抵靠静止的滚轮来保护门平衡机构。 通过正常驱动操作机构再次释放制动器。 在一种形式中，离合器布置在与驱动输入端同轴的固定轴上; 在第二形式中，离合器位于门筒的可旋转轴上。
