Abstract: A drive mechanism for use with an overhead shaft of a sectional door for raising and lowering the door via a rotation of the overhead shaft. The drive mechanism has a support structure, a first gear, a drive shaft, a second gear, a pocket wheel and an actuator. The second gear is interconnected to the first gear so that a rotation of the second gear is transmitted to the first gear and vice versa. The pocket wheel is operable between first and second positions. The second gear is rotatable along a first direction corresponding to a raising of the sectional door and along an opposite second direction corresponding to a lowering of the sectional door. The actuator is used for rotating the pocket wheel about the drive shaft, operating the pocket wheel between the first and second positions, and driving the second gear along the first and second directions when the pocket wheel is in the second and first positions respectively. The drive mechanism includes a first ratchet assembly for blocking rotation of the second gear along the second direction when the pocket wheel is in the second position. The drive mechanism may also include a second ratchet assembly for blocking rotation of the second gear along the first direction when the pocket wheel is in the first position.

Abstract translation: 一种驱动机构，用于与通过架空轴的旋转升高和降低门的分段门的顶架轴一起使用。 驱动机构具有支撑结构，第一齿轮，驱动轴，第二齿轮，凹槽轮和致动器。 第二齿轮与第一齿轮互连，使得第二齿轮的旋转传递到第一齿轮，反之亦然。 口袋轮可在第一和第二位置之间操作。 第二齿轮沿对应于分段门的升高的第一方向和对应于分段门的下降的相反的第二方向旋转。 致动器用于围绕驱动轴旋转凹槽轮，在第一和第二位置之间操作凹槽轮，并且当凹槽轮分别处于第二和第一位置时沿着第一和第二方向驱动第二齿轮。 驱动机构包括第一棘轮组件，用于当凹槽轮处于第二位置时阻止第二齿轮沿着第二方向旋转。 驱动机构还可以包括第二棘轮组件，用于当凹轮处于第一位置时阻止第二齿轮沿着第一方向旋转。
