Screw locking device for screw - has spreader component which expands screw and is self-locking in inserted position

Abstract

Abstract The device is for use with a screw securing two or more components together. A portion (3) of the screw (2) is expanded by the action of the conical portion of a spreader component (1), which is self-locking in the inserted position, thus preventing the screw working loose. The screw can have a conical recess (4), and to increase friction between it and the spreader component an intermediate layer can be fitted between them. There can be a stop (6) preventing excess expansion of the screw. The spreader component can have a screw thread, and its axis can be inclined to that of the screw. The design allows simple release of the screw and as often as desired.
