Description

Apparatus For Locking Screw-Threaded Fixing Devices
This invention relates to an apparatus for locking two screw-threaded fixing devices (as defined herein) substantially against rotation.
In the present specification a "screw-threaded fixing device" means a device having a screw-threaded part and a part having a non-circular periphery which can be engaged by a complementary-shaped tool for rotation of the device about the axis of the screw thread. Common examples of screw-threaded fixing devices are nuts and bolts. In a bolt, the screw-threaded part is its screw-threaded shank and the part having a non-circular periphery is the external (normally hexagonal) periphery of the head of the bolt. In a nut, the screw-threaded part is the screw-threaded aperture through the centre of the nut and the part having a non-circular periphery is the external (again normally hexagonal) periphery of the nut. In each case the complementary-shaped tool is typically a spanner or wrench. Another type of screw-threaded device is an Allen bolt whose head has a central hexagonal hole for engagement by an Allen key. In this case the non- circular periphery is the internal periphery of the central hole.
According to the present invention there is provided an apparatus for locking two screw-threaded fixing devices (as defined above) substantially against rotation, the apparatus comprising a first component having a first portion for engaging the non-circular periphery of the first device and a second portion for releasable fixing by the second device, and a second component having a first portion for engaging the non-circular periphery of the second device and a second portion for releasable fixing to the first component, whereby in use the first device is locked against rotation by the fixing of the first component by the second device while the second device is locked against rotation by the fixing of the second component to the first component .
There is also provided, as an independent invention, an apparatus for locking a nut or bolt substantially against rotation, the apparatus comprising a component having a substantially circular aperture for fitting around a nut or bolt head having an external periphery substantially in the form of a regular polygon, the aperture having a plurality of equiangularly-spaced radially inward projections, each projection being spaced outwardly of a notional straight line joining points on the circular aperture midway between that projection the projections immediately on either side, and means for securing the component against rotation.
The invention is applicable, for example, to locking of wheel nuts on an HGV, or rail track securing devices.
Embodiments of the invention will now be described, by way of example, with reference to the accompanying drawings, in which: Fig. 1 is a side view, partly in cross-section, showing a first embodiment of an apparatus according to the invention in use;
Fig. 2 is a plan view of the embodiment of Fig. 1;

Fig. 6 is a sectional side view of the component of Fig. 5;
Fig. 7 shows a stud and split pin used to secure the two components of the apparatus of Fig. 1 together;
Fig. 8 shows various alternative forms of the component of Figs. 3 and 4; and
Fig. 9 is an enlarged plan view of one end of yet a further alternative form of the component of Figs. 3 and 4.
In Figs. 1 and 2 an apparatus according to a first embodiment of the invention in shown in its position of use locking two substantially identical nuts 10A, 10B respectively against rotation. Each nut 10A, 10B has an upper body portion 12 with a conventional external periphery in the form of a regular hexagon, and a lower body portion in the form of a flared skirt 14. In
Figs. 1 and 2 the nuts are shown securing a plate 16 to an underlying body 18. To this end, the body 18 has a pair of upstanding substantially parallel threaded shanks 20A, 2 OB which pass freely through respective holes 22 in the plate 16, and the nuts 20A, 2OB are screwed onto the exposed parts of the shanks 20A, 2OB which project above the upper surface of the plate 16 so as to bear against the latter and secure the plate 16 to the body 18.
The locking apparatus comprises two components 24 and 26 each formed by stamping and bending from a flat steel sheet (see also Figs. 3 to 6) . The component 24 has a flat circular "head" 28 at one end with a regular hexagonal aperture 30 complementary to the hexagonal periphery 12 of the nut 10A so that the head 28 can be fitted over the nut 10A in the manner of a conventional ring spanner, as seen in Figs. 1 and 2. At its other end the component 24 has a flat circular "tail" 32 with a central aperture 34 whose diameter is slightly larger than the diameter of the shank 20B to allow the latter to pass freely through the aperture 34.
In use, the nut 10A is first screwed onto the exposed part of the shank 20A and tightened against the plate
16, the nut 10B not yet having been screwed onto the shank 20B. Now the head 28 of the component 24 is fitted over the nut 10A as shown, and the tail 32 fitted over the exposed part of the shank 2OB so that the latter passes through the aperture 34. In order to account for the skirt 14 on the nut 10A the component 24 is stepped at 36 so that the head 28 and tail 32 are disposed in substantially parallel spaced planes. Now the nut 10B is screwed onto the exposed part of the shank 20B and tightened against the tail 32, thus trapping the latter tightly between the nut 10B and the plate 16. At this point the nut 10A is locked against rotation by the fixing of the tail 32 of the component 24 by the nut 10B.
The second component 26 is now fitted to lock the nut
10B against rotation. The component 26 includes a flat circular "head" 38 which, like the head 28 of the first component, has a regular hexagonal aperture 40 complementary to the periphery 12 of the nut 10B so that the head 38 can be fitted over the nut 10A in the manner of a conventional ring spanner. The component 26 also has a "tail" in the form of a hook-like formation 42 which can engage a transverse slot 44 in the component 24, as seen in Figs. 1 and 2.
The second component 26 is fitted by first engaging the hook 42 in the slot 44 and then rotating the component so that its head 38 is brought down towards the nut 10B so that the latter enters the aperture 40, Figs, 1 and 2. In order to retain the second component 26 in that position the two components 24, 26 have apertures 46, 48 respectively which are aligned when the two components 24, 26 are fitted as aforesaid, and a stud 50 (Fig. 7) is passed through these aligned apertures and retained in place by a split pin 52. Thus the nut 10B is now also locked against rotation, by the fixing of the hooked tail 42 of the component 26 to the component 24. It will be evident that the trapping of the tail 32 below the nut 10B prevents the whole assembly from falling off the nuts. However, the assembly can be removed by removing the split pin 52 and stud 50, followed by removal of the component 26, and finally, after unscrewing the nut 10B, removing the component 24.
Although the components 24, 26 are shown in Figs. 1 and 2 as locking a pair of nuts 10A, 10B against rotation relative to threaded shanks 20A, 20B which project upwardly from the body 18 through the plate 16, it will be readily understood that the same components can be used, without modification, to lock a pair of bolts against rotation. Indeed, Fig. 1 can be interpreted such that 10A and 10B are in fact the heads of respective bolts whose screw-threaded shanks are 20A, 20B. In that case the shanks 20A, 20B of the bolts are screwed down into the body 18 through the respective apertures 22, the shank 20B passing through the aperture 34.
In other embodiments the components 24 and 26 may take various forms. For example, Fig. 8 shows plan views of two alternative forms of the component 24. As shown, the head 28 may be in the form of a conventional open- ended spanner rather than a ring spanner as in Fig. 3, and the tail 32 could be a simple bifurcation as shown in the lower diagram. The head 38 of the component 26 could also be in the form of a conventional open-ended spanner .
A particularly useful embodiment of the component 24 is shown in Fig. 9, wherein only the head 28 and the immediately adjacent portion of the component 24 is illustrated. In this case the head 28 comprises a substantially circular aperture 54 for fitting around a nut (or bolt head) 10 having an external periphery 12 substantially in the form of a regular polygon, such as the conventional hexagonal nut 10 shown. The aperture 54 has a plurality of equiangularly-spaced radially inwardly projecting humps 56, equal in number to the number of sides on the nut 10, in this case six. Each hump 56 is spaced outwardly of a notional straight line 58 joining points 60 on the circular aperture 54 midway between that 56 and the humps immediately on either side (obviously, with the nut 10 present, as seen in Fig. 9, the notional straight lines 58 are substantially coincident with the peripheral sides of the bolt) . The small gap between the humps 56 and the straight lines 58 allow the nut a limited range of rotation, say through 30 degrees, before the humps 56 come into contact with the sides of the nut. The advantage of this arrangement is that the nut (or bolt head) 10 does not have to be at a precise angular position for fitting the head 28. The component 24 can be advantageously provided in two forms, differing in the angular position of the humps. The two forms of the device, when compared with one another, will have sets of humps that are offset by 30 degrees. Thus, while the device illustrated in Fig. 9 may not fit a nut due to the humps interfering with the sides of the nut or the apexes between sides, the alternative device will fit the same nut since the humps of this alternative device will by exactly midway between the humps of the device which does not fit. One may therefore provide a kit of devices including a mixture of the two types, and for every angular position of a given nut, one or other device will fit the nut without the nut having to be adjusted.
Obviously, the humps can be dimensioned to allow a greater degree of rotation than 30 degrees (for a hexagonal nut) .
The head 38 of the component 26 can also be formed as shown in Fig. 9. This type of head design is also useful in other types of nut and bolt locking mechanisms .
Fig. 9 also shows a modification of the component 24 wherein the head 28 is joined to the main body of the component by a lost motion mechanism 62. This permits compensation for small tolerances in the distance between the nuts (or bolts) 10A and 10B. In another embodiment of the invention, not shown, the heads of the components 24, 26 are designed for engagement with the central hexagonal hole of an Allen bolt. Essentially, the head end of each component is formed like an Allen key for insertion into the central hole.
The invention is not limited to the embodiments described herein which may be modified or varied without departing from the scope of the invention.
