    Abstract: A cable tensioner for an industrial door helps keep a cable neatly wrapped on its take-up drum. In some embodiments, the tensioner functions in a first mode during normal door operation, and operates in a second mode when the tension in the cable decreases to a predetermined low level. When operating in the second mode, the tensioner is able to take up slack in a cable that supports a door member, such as a door panel or a deadweight that counteracts the door panel's weight. The tensioner includes a shock absorber that resists a reaction force pulling on the tensioner when the tensioner is in the second mode. The tensioner may be adapted for use on various doors including, but not limited to, sectional doors, roll-up doors, high-lift doors, horizontally storing doors, vertically storing doors, and various combinations thereof.

    Abstract translation: 用于工业门的电缆张紧器有助于将电缆整齐地包裹在卷绕鼓上。 在一些实施例中，张紧器在正常门操作期间以第一模式工作，并且当电缆中的张力降低到预定的低电平时，张力器在第二模式中操作。 当在第二模式下操作时，张紧器能够承受支撑门构件的电缆中的松弛，例如门板或者与车门板的重量抵触的自重。 张紧器包括当张紧器处于第二模式时抵抗拉伸器上的反作用力的减震器。 张紧器可以适用于各种门，包括但不限于分段门，卷起门，高层门，水平存放门，垂直存放门及其各种组合。

    Abstract: A mechanism and method for operating a track-mounted door is disclosed. The mechanism includes a pair of side drums that are connected by first cables to the bottom of the door. The side drums are coaxially mounted on a shaft for simultaneous rotation with a pair of cable drums. The cable drums are connected to high pressure gas struts by second cables. Each second cable is carried around a shiv wheel that slides along a guide track as the second cable moves. Each shiv wheel is operatively connected to one of the gas struts. As the shiv wheel moves along the guide track toward the cable drum, the gas strut is charged. As the shiv wheel moves away from the cable drum, the gas strut is discharged. A standard electric motor and screw driven lift-arm is used to initiate the opening and closing of the door. The charged gas strut stores sufficient energy to overcome friction and gravity to assist the electric motor and lift-arm to open the door.

    Abstract translation: 公开了一种用于操作轨道安装门的机构和方法。 该机构包括一对侧鼓，其通过第一缆线连接到门的底部。 侧鼓同轴地安装在轴上以与一对电缆鼓同时旋转。 电缆鼓通过第二根电缆连接到高压气体支柱。 每个第二根电缆都围绕着随着第二根电缆移动而沿导轨滑动的滑轮。 每个翼轮可操作地连接到气体支柱之一。 当车轮沿着导轨移动到电缆鼓时，气体支柱被充电。 当车轮离开电缆鼓时，气体支柱被排出。 使用标准的电动机和螺杆驱动的提升臂来启动门的打开和关闭。 带电气体支柱存储足够的能量来克服摩擦和重力，以帮助电动机和升降臂打开门。

    Abstract: An adjustable speed gas spring primarily adapted for use has a part of a door closing mechanism. The gas spring includes a piston assembly which is disposed within an elongated fluid chamber and which upon relative rotation of the shaft with respect to the tubular body, permits the user to adjust the shaft extension velocity. The gas spring is fully functional in any shaft orientation.

    Abstract: The invention described is a device or apparatus for automatically returning a sliding door or window to a predetermined position within a stationary frame, which incorporates a cable anchor on the frame; a hollow housing on the sliding closure having axially aligned elongated compartments in the housing, the more distant of which from the anchor is fluid-tight; a traveling block axially movably disposed in the closer compartment; a cable from the anchor reeved through sheaves in the traveling block; a tensioner connecting the traveling block with a partition between the compartments and biasing the traveling block away from the anchor to prevent shock in the system when slack is introduced into the cable by manual movement of the closure; the more distant compartment being divided into two fluid-tight chambers communicating at their adjacent ends; a rod longitudinally movably disposed through the traveling block and one chamber; a resilient compression device biasing the rod and the traveling block away from the anchor; a movable valve mounted on the rod to regulate fluid flow between the opposite ends of the chamber, the valve blocking or restricting longitudinal fluid flow within the chamber when the closure moves from the predetermined position and permitting flow when the closure moves toward the predetermined position; and the valve and fluid communication conduits cooperating to control the speed of movement of the rod urged by biasing of the compression device; whereby the closure is returned to the predetermined position at a preselected speed and without shock.
