Safety device particularly for multiple wheel nuts

摘要

A safety device ( 10 ) comprises a plurality of wheel nut position indicators ( 30 ) captively but rotatably mounted in a holder ( 12 ). The position indicators are attachable to respective wheel nuts ( 40 ) by means of fastener covers ( 50 ). When attached, the fastener covers ( 50 ) act to secure the device to a wheel and to transfer any rotational movement, i.e. loosening, of a wheel nut ( 40 ) to an associated position indicator ( 30 ). The indicators ( 30 ) each have an indicator portion, e.g. a triangular pointer ( 34 ) and are so arranged that this portion emerges from the holder and hence becomes visible when any such rotation occurs. By removing a fastener cover ( 50 ) an indicator ( 30 ) is disengaged from a wheel nut ( 40 ) and the individual wheel nut can be tightened without having to remove the entire device ( 10 ).
