Abstract: There is provided a rotation indicator device for mounting onto a polygonal fastener, such as a wheel nut. The device comprises a body having a bore. A pair of tapered regions, which are formed of a resilient material, extend around a periphery the bore, each of the regions being resiliently deformable to, in use, securely and releasably mount the body onto the polygonal fastener such that a rotation of the device relative to the polygonal fastener is inhibited. The device may be used as a safety device to indicate the rotation, i.e. loosening, of the polygonal fastener.

Abstract: For indicating rotational displacement between an Allen bolt having a bolt head (34) provided with a central recess (36) for engagement by a fastening/unfastening tool, namely an Allen key, and a substrate to which the bolt is fastened, thereby to indicate whether the bolt has loosened, a safety indicating device is provided comprising a body (10) having a bore formed with splines (12) for engagement over the bolt head (34). The body (10) also has an end closure (14) formed with a plug (16) projecting inwardly of the bore for snug engagement into the central recess (36) of the bolt head. An indicator is also provided on the body (10). This is typically a pointer (18) mounted or formed on the body and projecting laterally, but it could be an indicator which is merely marked or formed on the body without projecting outwards.

Abstract: For mounting on a wheel nut or similar a rotation indicator device includes a body of one piece construction having an annular portion to releasably fit in non-rotatable manner onto the nut and having an end wall portion provided with an indicator. The indicator is provided within the periphery of the device, at a position which, in use, overlies the nut to which it is fitted, by having at least one opening in the end wall portion with free edges configured as the indicator (e.g. pointer with tip). The one piece device may also include side walling of part annular configuration extending between the annular portion and the end wall portion with the free edges being where the side walling is not connected to the end portion. A support post may then extend between the annular portion and the end wall portion at a location remote from the side walling.

Abstract: A rotation device for a wheel nut comprising a body having a bore formed with equi-spaced grooves enabling the device to be releasably but non-rotatably secured to the wheel nut in one position of a plurality of positions, and a cap which fits removably into or onto one end of the body to close off the bore. The cap comprises a means to indicate the rotational position of the device relative to a reference. So that the height of the body may be chosen to allow it to extend through a raised wheel trim, but not project too far above, the body is formed at its end to which the cap fits with at least one removable top section strip, which may be delimited by respective continuous notches around the periphery of the body at the interior and/or exterior thereof.

Abstract: A rotation indicator device comprises a body having a bore, whereby the body is adapted to be releasably mounted on a polygonal fastener or other multi-angled component in any selected position. At least part of the body which defines the bore is formed of a resilient material of suitable grip and flexibility characteristics, such as silicone rubber material, and the bore has an edge margin which is of a tapered profile in cross-section so that the body can be snugly mounted onto the fastener or other component without any relative rotation occurring between the device and the fastener or other component.

Abstract: A metal wire is configured to provide a diagonal interconnecting part extending tangentially between first and second coils which are sized to fit around respective screw action connectors. First and second wire end portions extend tangentially from the respective first and second coils across and beyond the diagonal interconnecting part to provide first and second finger grip limbs. The first limb extends across the interconnecting part adjacent the first coil and the second limb extends across the interconnecting part adjacent the second coil so that end regions of the limbs are spaced apart and at opposite sides of the interconnecting part and are capable of being pressed towards each other in a direction transverse to the interconnecting part by the fingers of one hand in order to loosen the respective coils to enable their location over, or removal from, the respective screw action connectors.

Abstract: 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).

Abstract: For indicating relative rotational displacement between a fixed first member, such as a stud (20) on a wheel hub, and a second member, such as a wheel nut (22), which is rotatably engaged with the first member, a safety device (24) comprises a body (26) having a bore formed with equispaced grooves enabling the device to be releasably secured to the second member (22) in one position of a plurality of positions and having indicating means, such as a pointer (28), to indicate the position of the device (24) relative to a reference, such as a mark (32) on the rim (16) covering the wheel hub (14). The bore within the body (26) is closed at one end, e.g. by bevelled top wall (36), so that the body additionally serves as a dust cap for the conjoined first and second members (20, 22).

Abstract: In order to provide a visible indication of loosening of a nut or a bolt relative to another member to which it is threadably engaged, a rotation indicator assembly comprises a first element, which is permanently secured to the nut or bolt and a second element which is adapted to be releasably and non-rotatably mounted in or on the first element, e.g. by interengagement with teeth in any chosen rotational position, and incorporates means, such as pointer, for indicating its rotational position relative to a fixed reference. The first element may take the form of an insert, an integral formation, or an external fitment. The fixed reference may be provided by an independently mounted marker secured by the nut or bolt.
