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 braking device configured for use with the counterbalancing system of a garage door. The braking device includes a support bracket, a ratchet wheel, a pawl arm, and a biasing spring. The support bracket is rigidly connected to a fixed structure and has a guiding slot. The ratchet wheel is securely mounted about the overhead shaft of the counterbalancing system and has at least one notch. The pawl arm has first and second ends, the first end of the pawl arm being pivotally connected to the support bracket and the second end of the pawl arm cooperating with the guiding slot and being movable with respect to the support bracket along said guiding slot. The first and second ends of the pawl arm are further connected to flanges of a plug on either side of the overhead shaft. The biasing spring is operatively connected between the support bracket and the pawl arm so as to exert a biasing force for biasing the pawl arm towards the ratchet wheel. The pawl arm is devised so that, an element thereof is adjacent to the ratchet wheel, said element being shaped and sized to be removably insertable into at least one notch of the ratchet wheel so as to block rotation of the ratchet wheel, and thus block rotation of the overhead shaft, in the event of a failure of the counterbalancing system of the door.

Abstract: A cable failure device for a mobilizing a garage door in the event of a failure of one of the cables or one of the elements holding the cables is described. The cable failure device of the invention includes a support structure mounted on the cable operated door and includes a connection point onto which a tensioned cable is connected. A braking assembly is mounted onto the support structure and includes a casing mounted onto the support structure and a brake operable between a rest position and an operable position. The brake is movably mounted to the support structure and is located adjacent the outside of a fixed frame such as guide rails and is adapted to co-operate with a roller on the garage door so that a portion of the guide rail lies between the roller and the brake. A tension detector co-operating with the tension cable is provided for detecting a tension in the tension cable and an actuator is operatively connected to the tension detector and to the brake. When the brake is in the rest position, the rollers guide the door along the rail and when the brake is triggered into the operable position by a loss of tension in the cable detected by the tension detector, it causes the actuator to actuate the brake so that it engages the outside of these rails, thereby urging the brake and one of the rollers towards each other. This combined action brakes the movement of the cable operated door and thus impedes its free falling to the ground, thereby preventing damages and injuries.

Abstract: The plug is for use with a torsion spring and is removably connectable to a component of a counterbalancing mechanism. The plug comprises a generally circular base and a hollow body coaxially projecting from the base. The body has an outer surface for receiving an end of the torsion spring. At least two spaced-apart connection flanges are axially projecting from the base and opposite to the body. Each flange comprises a pair of opposite side shoulders. The flanges are removably inserted into the component for connecting the plug thereto in interfering engagement. Plugs that are constructed accordingly create modular and versatile sub-assemblies with other components. Such plugs are then easily secured in place and do require an extensive inventory of parts to accommodate all situations.

Abstract: A cable failure device for a cable-operated door operated by a tensioned cable, the cable-operated door having a movement guided along a fixed structure, such as a guide rail. The cable failure device is configured for cooperating with the tensioned cable so as to immobilize the cable-operated door with respect to the fixed structure in the event of a loss of tension in the cable. The cable failure device included a support bracket for mounting the cable failure device onto the door, a guiding assembly operatively mounted for guiding the movement of the door along the fixed structure, and a braking assembly operatively mounted onto the support bracket, and operable between a rest position where the guiding assembly is allowed to guide the door along the fixed structure, and an operable position triggered by a given loss of tension detected in the tension cable where the braking assembly engages a portion of the fixed structure for braking movement of the cable-operated door with respect to the fixed structure. The cable failure device also includes a safety arm operatively connected to the braking assembly and cooperating with the tensioned cable so as to detect the given loss of tension. The safety arm is operable between a safety configuration where it is positioned over at least one fastener of a corresponding hole of the support bracket when there is still a given tension in the tensioned cable, for preventing a user from removing the support bracket from the door, and a retracted configuration where the safety arm is positioned away from the fastener when the given tension is no longer present in the cable, thereby enabling the user access to the fastener. Thus, the cable failure device is configured for immobilizing the door in the event of a loss of tension and for preventing a user from removing the device from the door when there is still tension in the cable.
