  • Patent number: 10351385
    Abstract: A pawl-less retractable comprises an inner frame with a drum-sperrad assembly mounted to the inner frame between side members of the frame to rotate relative to the frame. The inner frame is pivotally mounted to a stop cap above the drum-sperrad assembly such that the frame, and hence the drum-sperrad assembly, can pivot relative to the stop cap. The stop cap comprises a central body, a leading wing extending from a first side of the central body and a trailing wing extending from a second side of the central body opposite said first side. In use, the inner frame and drum-sperrad assembly can pivot relative to the stop cap or alternatively an outer frame, between an unlocked position in which the teeth of the sperrad are inside of an engagement zone circle and a locked position in which the teeth are outside of the engagement zone circle.

  • Patent number: 8015676
    Abstract: A snap hook that includes gate that includes and aperture that accepts a male portion that protrudes from the nose portion of the hook is disclosed. The coupling of the nose portion and the gate prevents the unwanted opening of the gate while the hook is under extreme loads. Still further, the use of a slide bar that is moved through translation and rotation when opening the gate of the hook is also disclosed. The translation and rotation motion provides improved cooperation of the components and improves the resistance of undesired movement of the slide bar by forces against a protrusion on the slide bar, and thus provides greater resistance to unwanted opening of the gate.
