  • Patent number: 5700249
    Abstract: The protector comprises a protective element, e.g. a cap (16), movable in use along the implement between an inoperative position in which it exposes the pointed end or sharp edge portion of the implement and an operative position (FIG. 3) in which it covers the pointed end or sharp edge portion of the implement. The protector also comprises a holder (15) for fitting to the implement and a device, e.g. arm (17), connecting the protective element to the holder to in use allow the protective element to move along the implement between the inoperative and operative positions but to prevent separation of the protective element from the implement. In a preferred embodiment, the protective element flips into a tilted position to prevent unintentional movement of the protective element from its operative to its inoperative positions.
