ABSTRACT:
A self-locking hub for a computer tape drive that uses tape tension along to actuate a tape reel torque lock. In a preferred embodiment of the invention, the torque provided by tape tension after tape is threaded from a supply reel to a take-up reel provides sufficient force to actuate an over-center, spring-tensioned engagement pawl-like hub lock mechanism that engages an inner surface of a tape reel with sufficient force to secure the reel to the hub. More than one such self-locking mechanism may be provided for a single hub to provide additional locking force. In an alternative embodiment, the self-locking engagement pawl can include an engagement flange that prevents a tape reel from being pulled off the hub or from falling off a vertically-oriented hub, thus providing additional security. In yet another embodiment of the invention, the hub lock mechanism comprises a deformable torque clutch that deforms to an expanded diameter upon application of torque in one direction, and returns to a smaller at-rest diameter upon release of such applied torque.
