Abstract: A window blind lock assembly includes a dog pivotally mounted in a casing to prevent movement of a blind string relative to the casing. The dog is resiliently biased to lock the string in the casing. A lever is pivotally mounted in the casing, and coupled to the dog and string. As the string is pulled, the lever rotates the dog to release the string. Conveniently, the string need not be pulled in any specific direction to release the dog.

Abstract: A greasable wheel hub (20) using a constant-velocity (CV) joint (22) as a hub spindle is taught. The wheel hub (20) includes a hub cover (28) attached to a hub body (24), which in turn is attached to a CV housing (32) and a CV bearing (34), both of which are portions of the CV joint (22). A grease (146) is injected through a grease fitting (136) into a grease trough (142) at the interface between the hub cover (28) and the hub body (24). This grease (146) is then conveyed through a plurality of grease passages (144) to the CV housing (32), where it provides lubrication for the CV joint (22). Another grease (246) is injected through another grease fitting (236) into another grease trough (242). This grease (246) is then conveyed though a plurality of other grease passages (244) and a plurality of grease channels (248) to the CV bearing (34), where it provides lubrication.
