    Abstract: A door operator mounted upon an elongated rail and adapted to open and close an upwardly acting door having horizontally hinged sections supported on tracks. An elongated, helical spring extends lengthwise within the rail and is rotated by drive means mounted on the rail. A traveling nut is engaged with the helical spring and is connected to the door so that rotation of the helical spring causes the traveling nut to move lengthwise of the track to operate the door. Switch means are responsive to the compression and expansion of the spring to deenergize the drive means.

    Abstract: A roll-type door for closing an opening in a wall and having a plurality of horizontally hinged, relatively narrow slats, the lengthwise ends of which move along upright guide tracks mounted upon the wall adjacent the opposite sides of the opening. The door, when in opened position, is wound upon a plurality of flanged disks, some of which are secured to a shaft rotatably supported above the opening. Spring-biased counterbalance means yieldably resists downward unrolling movement of the door which can be effected manually, by a chain drive, or by a shaft and gear arrangement.

    Abstract translation: 一种用于封闭壁中的开口并具有多个水平铰接的相对狭窄的板条的辊型门，其纵向端部沿安装在邻近开口的相对侧的壁上的直立导轨移动。 当门处于打开位置时，门被卷绕在多个凸缘盘上，其中一些被固定到可旋转地支撑在开口上方的轴上。 弹簧偏置的平衡装置可以有效抵抗门的向下展开运动，这可以通过手动，链条驱动，或通过轴和齿轮装置进行。

    Abstract: 1,217,928. Up-and-over door structure. OVERHEAD DOOR CORP. 9 Dec., 1968 [21 Dec., 1967], No. 58324/68. Headings E2F and E1J. An up-and-over door is made of horizontal panels, each mounted on a frame whereby they are hinged together. The frame of the lower of the two members has a rail 23A formed with a horizontal wall 24A. A flange 29A extending downwardly from the wall has an upper, preferably arced, portion 33A and a lower flat portion 34A which is attached to the rear flange 36A of the end of the panel. A support flange 37A extends inwardly from the lower edge of the arced portion and has a hollow semi-cylindrical portion 38A at its end. The frame of the upper of the two members has a rail 22 with a horizontal wall 42. A flange 52 extends downwards from this wall and has attached to it a flange 56 which extends backwards and preferably carries a cylindrical portion 57 on its end which is disposed within the hollow cylindrical part of the other member. Flange 56 has a ridge 59. A channel shaped bearing member 63 of selflubricating material is disposed between the two hinge members, fitting between the two cylindrical portions. The front edge 65 of this bearing member is preferably curved to engage, with the curved flange 33A.
