摘要： The assembly comprises an extension spring anchored at one end to a winch mounted to the door opening frame. A double-grooved pulley is mounted on a plate secured to the free end of the spring. A fixed second double-grooved pulley is mounted to the door frame. A pair of cables are anchored at one end to the door frame and extend in parallel to pass around the two pulleys. After the second pulley, the cables separate and extend down to the bottom corners of the door, to which they are secured. Upon release of the door latch with the door down, the spring contracts and, through the first pulley, applies an equal pull to the two cables so that they move at the same rate, thereby raising the door smoothly.
摘要翻译：组件包括一个延伸弹簧，其一端固定在安装在门开口框架上的绞盘上。双槽滑轮安装在固定在弹簧自由端的板上。固定的第二双槽皮带轮安装在门框上。一对电缆在一端固定在门框上，平行延伸以绕过两个滑轮。在第二滑轮之后，电缆分开并向下延伸到门固定的门的底角。当门向下滑动时，弹簧收缩，并且通过第一滑轮对两根电缆施加相等的拉力，使得它们以相同的速率移动，从而平稳地升高门。

摘要： A roll-up door for enclosing the doorway in a building. The door comprises a horizontal rotatable drum mounted above the doorway and a flexible door panel is wound on the drum. A pulley is secured to each end of the drum and the first ends of a pair of belts are secured to each pulley and the belts are wound in overlapping relation on pulley so that adjacent convolutions of each belt are separated by convolutions of the other belt. The free end of one belt is dead-ended on the frame, and a counterbalancing weight is attached to the belt intermediate its ends and exerts a counterbalancing force to wind the door panel on the drum. The free end of the second belt is connected to the lower end of the door panel and a pair of springs are connected to the second belt intermediate its ends and the springs exert a tensioning force to stretch the door panel when the door panel is in the closed position.
摘要翻译：用于封闭建筑物中的门口的卷起门。门包括安装在门口上方的水平可旋转滚筒，并且将柔性门板卷绕在滚筒上。滑轮被固定到滚筒的每一端，并且一对皮带的第一端固定到每个皮带轮上，并且皮带在皮带轮上以重叠的关系缠绕，使得每个皮带的相邻卷绕体被另一皮带的卷绕分开。一个皮带的自由端在框架上是死端的，并且平衡重物在其端部附近附接到皮带，并施加平衡力以将门板卷绕在鼓上。第二带的自由端连接到门板的下端，并且一对弹簧在其端部之间连接到第二带，弹簧施加张紧力以在门板处于门板时拉伸门板关闭位置。

摘要： A retainer to restrain pieces of a coil spring from scattering when the spring breaks under tension makes use of two mutually slidable elements located within the interior of the coil spring. Adjacent ends of the elements have a sliding engagement with each other and include a yieldable cushion inherent in the structure to absorb the impact when the spring breaks. The respective opposite ends of the elements are attached, one to the spring keeper at one end of the spring and the other to the spring keeper at the opposite end of the spring.

摘要： A lift up door of the spring assisted type, particularly for garages, in which the door is mounted on a pair of columns in the door opening by a lever and bracket system. The springs are connected to levers on either side of the door to counterbalance the door weight. A further pair of levers are provided for connection between the door and the columns to control movement of the door, the arrangement being such that the door when in the UP or OPEN position is locked against accidental movement to the DOWN or CLOSED position.
