    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 ratched 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: A chain guide for guiding a chain within a chain hoist. The chain guide includes a substantially elongated body having an inner side and an outer side, along with first and second extremities. The substantially elongated body is made of a substantially flexible material for curving the substantially elongated body into a substantially arched configuration about a given wheel of the chain hoist. The chain guide also includes first and second chain receiving portions provided adjacent to the first and second extremities respectively of the substantially elongated body, on the inner side thereof. Each chain receiving portion comprises a pair of shoulders protruding from the inner side of the body and defining an open channel shaped and sized for slidably receiving a portion of the chain. The chain guide also includes a deformable connecting portion for interconnecting the first and second chain receiving portions of the chain guide. Also described is a chain hoist provided with the chain guide.

    Abstract: A chain keeper for retaining a chain operatively connected to a driving mechanism of a chain hoist system. The chain keeper has a support bracket an d a pair of plates. The support bracket is mountable onto a fixed structure, and has a substantially vertical longitudinal axis, and opposite top and bottom sections. Each plate has top and bottom portions. The plates project from the support brack et and are slanted with respect to the longitudinal axis thereof. The plates conver ge towards one another towards the bottom section of the support bracket, a slo t being defined between peripheral edges of the plates at the bottom section o f the support bracket. The slot is shaped and sized to slidably and removably receive therein a segment of the chain for retaining the same from substantial vertical movement along the longitudinal axis of the support bracket.
