Abstract
A key includes a blade having an axially-extending window formed by an opening through a thickness of the blade between two opposite faces thereof, and a set of rollers mounted in series along the window, with each roller being freely rotatable around a spindle fixed transversely across the window in a width direction of the blade. The key may be a security key designed to cooperate with a pin tumbler cylinder.
Claims19
A key comprising:
- a blade having a first side face and an opposite second side face, the first side face and the second side face having a length extending in an axial direction, and a width extending in a direction perpendicular to the axial direction;
- a window extending in the axial direction and being formed by an opening through a thickness of the blade from the first side face to the second side face;
- at least two spindles fixed transversely across the window in the width direction;
- and
- at least two rollers, each of the at least two rollers being mounted to one of the at least two spindles such that the at least two rollers are freely rotatable around a respective one of the at least two spindles without touching one another.
