    摘要： An operator for an overhead door comprises a fluid actuated device including a cylinder and a cooperating piston. The piston rod carries a pair of cable sheaves. Another pair of sheaves are rotatable on a fixed mounting. A cable is wound around pulleys in corresponding pairs. Each cable has one end anchored and another end fastened to the door so when the fluid actuated devices spread the pair of sheaves, the door lifts. Pressurized fluid is relieved from the cylinder to let the door close under its own weight. Electric circuits for actuating the hydraulic circuit are shown.

    摘要： A self-closing, sliding door assembly in which a latch arm is pivotally mounted for selective movement into engagement with a counterweight that is connected to a sliding door movable between open and closed limits, the counterweight tending to move the door to the closed limit and the latch arm selectively holding the door in the open limit. The latch arm is weighted to move automatically out of engagement with the counterweight as the counterweight load is removed from the latch arm as the door is moved a further distance in the direction of the open limit, thereby releasing the counterweight to move the door toward the closed limit. More particularly, the latch arm has one end selectively movable under the counterweight while a stop limits rotation of the latch arm so that the latch arm can support the counterweight. The other end of the latch arm is weighted relative to the one end engageable with the counterweight so that the latch arm will pivot automatically under gravity to a position in which the one end is disengaged from the counterweight when the counterweight load is removed from the arm.

    摘要翻译： 一种自闭合滑动门组件，其中，锁定臂枢转地安装成用于选择性地移动与配重相连接，该配重连接到可在打开和关闭极限之间移动的滑动门，所述配重倾向于将门移动到关闭极限， 闩锁臂选择性地将门保持在开启极限。 当门沿着打开极限的方向移动更远的距离时，当配重负载从闩锁臂移除时，锁定臂被称重以自动脱离与配重的接合，由此释放配重以将门朝向 封闭限制。 更具体地，闩锁臂具有可选择性地在配重下移动的一端，同时停止限制闩锁臂的旋转，使得闩锁臂可以支撑配重。 闩锁臂的另一端相对于可与配重接合的一端被称重，使得当重力负载从臂移除时，闩锁臂将在重力作用下自动地枢转到一端与配重脱离的位置 。

    摘要： A door having horizontally hinged sections is supported upon reinforced track means for movement between an upright closed position and an open position. A counterbalance mechanism, which is mounted upon the wall above the opening, is connected to the door to counteract gravity. The counterbalance springs are connected to fusible link means which melts at a predetermined temperature and thereby reduces the tension on the springs so that the door will close under the force of gravity. Governor means is rendered operative when the fusible link is ruptured to control the closing movement of the door.

    摘要： A refrigerator cabinet having an access opening and a door for closing the access opening is provided with a hinge construction assuring the self closing of the door from a substantially open position and the positive sealing of the door gasket with the cabinet base as the door approaches its closed position. In accordance with the preferred embodiment of the invention, the hinge construction also includes means for positioning the door in a predetermined open position as for example at an angle of 90* with the face of the cabinet.
