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 device (1) for use with a cable-operated door (3), such as garage doors (3) and the like, and a door assembly including the same. The device (1) is intended to reduce the risk of the door (3) falling, or at the very least slow down its descent, in the event of a failure in the counterbalancing mechanism of the door (3), which is generally represented by a loss of tension in a given tensioned cable (5) operating the door (3). The brake device (1) includes a support bracket (9), and a guiding assembly (15) and a braking assembly (17) mounted onto the support bracket (9). The braking assembly includes a swivel component (18) having opposite braking arm (19) and lever portion (20), the lever portion cooperating with the tensioned cable (3) so that in the event of a loss of tension in the cable (5), the braking arm (19) is urged onto an adjacent rail (7) via biasing means (21) for anchoring a knife (45) of the braking arm (19) into the rail (7) and stopping, or at the very least, slowing down the descent of the door (3), with respect to the rail (7).

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.
