Definitions

  • This invention relates to locking devices wherein, for the locking effect, one component is wedged into a corresponding recess in another component.
  • one of the components is a shank which has at one end thereof a recess which is of tapering configuration either from the end of the shank in the direction along the axis of the shank to a location inwardly of the end thereof or in the opposite direction.
  • the recess will be of frustoconical or conical configuration and will be of reduced cross sectional area in a direction from the end of the shank towards said location inwardly of the end of the shank, and along the shank axis.
  • the other component in these embodiments is a plug of corresponding shape which is adapted to be forced into the recess to provide the locking effect.
  • the invention has particular application to a vehicle wheel stud, which has the tapered recess at the end on which the wheel locking nut is screwed.
  • the plug which may be part of a bolt, is forced towards that end in providing the locking effect.
  • the shank is a threaded stud or bolt shank which can be screwed into a corresponding aperture, so that when the shank is in position, the plug can be forced into the recess in order to cause locking of the shank in position.
  • Bolts and studs of this type are used extensively in circumstances where fixing is to take place in an environment where vibration can be expected e.g. operating machinery, vehicles and the like, to ensure that the threaded shanks will not work loose as a result of the environmental vibration.
  • the use of such fixing arrangements are particularly important in aircraft, for obvious reasons.
  • the shank When the shanks are threaded, at the said end accommodating the recess, the shank may be provided with radial slits so that the end is split into segments which can splay as the plug is forced into the recess, to enhance the locking effect.
  • Fixing devices of the type to which the invention relates have been proposed heretofore, and indeed in my International patent application No GB 94/01607, I have set forth a number of suggestions for threaded fixing devices which are useful in many applications. Also, somewhat similar fixing devices are disclosed in US patent No 3,042,094. These previously proposed fixing devices however would not meet the present testing standards for locking efficiency, but the improvement according to the present invention has resulted in a fixing device which does meet higher standards of security under test conditions, and therefore the invention meets its objective of providing higher locking efficiency compared to the prior art devices.
  • a locking device comprises a first component in the form of a shank having a tapered recess in one end thereof, and a tapered plug, which is adapted to be forced into the recess in order to provide the locking effect, characterised in that the included taper angle of the recess differs from that of the plug whereby as the plug is forced into the recess, initially there will be line ring contact between the recess and plug surface, the relationship between the included taper angles of the recess and plug being such that when the plug is fully driven home to the locking position, the splaying of the shank around the recess will be such as to provide or provide more face to face contact between the recess and plug surface.
  • the included taper angle of the recess is preferably less than that of the plug.
  • the taper of the recess is increased or notionally increased as the plug is forced thereinto until the taper of the recess matches or moves towards the taper of the plug, providing the effective locking arrangement.
  • a particular advantage of this construction is that initially when the plug is first inserted into the recess there will only be circular line contact between the plug surface and recess. This means that as driving of the plug into the recess takes place, there will only be relatively little frictional engagement between the recess and plug, which means that the plug can be driven in by the application of a reasonable and manageable force, which can be applied by a suitable screw arrangement, in the preferred case. As the plug enters the recess however the recess angle changes or tends to change, and this may be enhanced by providing slits in the end of the shank which are divided into sections so that the sections can splay or tend to splay to provide the locking effect.
  • the plug may have tongues on its surface which engage in the slits, to stop the plug from turning in the recess or from tending to turn.
  • the plug at the narrow end is provided with an integral cylindrical projection of which the outer surface is threaded, and this projection is adapted to be threaded into a blind bore in the shank at the inner end of the recess, the plug also preferably being provided at its wider end with a drive means such as a bolt head or a recessed hexagonal drive arrangement, for receipt for example of an Allan key.
  • a drive means such as a bolt head or a recessed hexagonal drive arrangement
  • the plug may have a through bore for the receipt of the threaded stem of a locking bolt which passes through the plug and engages the threaded bore in the shank.
  • the locking bolt may be a cap head screw provided with a recessed hexagonal drive.
  • the shank may have a through bore leading from the recess to the other end of the shank, and that bore receives the locking bolt which is capable of being turned from the other end of the shank.
  • the locking bolt in such case would engage a threaded bore in the plug, to enable the plug to be drawn into the recess from the other end of the shank.
  • the locking bolt preferably is provided with a locking washer at the head end which can apply a tensioning effect to the locking bolt when it is in the locked position insofar as the locking washer will tend to force the bolt out of the other end of the shank, whilst the locking plug tends to force the locking bolt in the opposite direction, and the result is the maintenance of tension in the locking bolt, when in the locked condition.
  • the shank will in the majority of cases be a threaded shank, and will either form a stud on the shank of a fixing bolt or a headless shank.
  • the locking bolt When the invention is applied to a masonry fixing device, the locking bolt may be completely located in the shank, in a first bore, and a standard scaffold or other means may be adapted to be screwed into a second and larger bore at the other end of the shank from the plug and recess.
  • Figs. 1, 2 and 3 show perspective exploded views of fixing devices according to first, second and third embodiments of the invention
  • Figs. 4 and 5 are side views of the bolt and plug as shown in Fig. 1, to illustrate the taper angles;
  • Figs. 6, 7 and 8 are views of three additional embodiments of devices according to the invention, which are useable as masonry fixing devices.
  • Fig. 9 is a side view of another embodiment of the invention in the form of a wheel stud
  • Fig. 10 is a view similar to Fig. 9 showing another embodiment of wheel stud.
  • Fig. 11 is a cut away perspective view of a vehicle wheel provided with studs according to embodiments of the invention.
  • reference numeral 10 indicates a bolt having a hexagonal drive head 12 and a threaded shank 14.
  • the shank 14 is slotted as indicated at 16, at four positions which are spaced equiangularly by 90°.
  • the shank 14 is recessed to provide a frustoconical recess 18 of which the largest diameter is at the extremity of the shank end.
  • the recess 18 tapers to an axial threaded blind bore 20 which, as will be explained, is for receiving the threaded end 22 of a plug 24, said plug 24 comprising a frustoconical portion 26 having in the larger end a hexagonal drive hole 28 by which the plug 24 may be turned by a conventional Allan key.
  • the basic operation of the arrangement shown in Fig. 1 is that the bolt 10 is threaded into a correspondingly threaded hole (which could be in a nut) at some location where the bolt is to be used, and then the plug 24 is inserted in recess 18 until the threaded extension 22 engages the threaded bore 20.
  • the plug is now turned by means of an Allan key engaged in aperture 28 so that the plug is progressively driven into the recess 18.
  • the taper portion 26 of the plug engages the wall of the recess 18, and with continued turning of the plug, so the segments of the end of the shank 14 between slots 16 are splayed outwardly and lock in the aperture or nut in which the end of the shank is engaged.
  • the bolt 10 may be threaded into a bore and the plug 24 serves to lock the shank 10 in that bore, or alternatively the bolt 10 may be used in conjunction with a nut which is threaded onto the end of the bolt having the slot 16 after the bolt is placed in postion, and after the nut is applied, the plug 24 is screwed into the shank end to lock the shank to the nut.
  • the plug 24 is frustoconical, but is not provided with the threaded extension 22. Instead, the plug 24 has a through bore 30 for receiving a locking bolt 32, and the large end of the plug 24 is recessed as indicated at 34 in order to receive the head 36 of the locking bolt.
  • the locking bolt 36 is used in conjunction with a spring or lock washer 38 of conventional design.
  • the bolt 32 is positioned so that its shank passes through bore 30 in plug 24, and so that its head 36 engages in recess 34, the washer 38 having been placed on the locking bolt shank prior to this initial assembly.
  • the locking bolt 32 is screwed into the end of the shank so that its threaded shank engages in threaded bore 20, and locking of the bolt 10 is achieved in the manner described previously in relation to Fig. 1.
  • the plug 24 is provided with a threaded bore 40 as shown, the threaded extension 22 again being omitted.
  • the bolt 10 is provided with a through bore 42 for receiving a locking bolt 44, and the head 12 of the bolt 10 is recessed at 46 in order to receive the head 48 of the locking bolt 44.
  • Head 50 of the locking bolt 44 is provided with a hexagonal drive recess for engagement by an Allan key for the turning of the bolt 44.
  • the bolt is locked in position from the head end and prior to use of the bolt, the locking bolt 44 is, after placement of locking washer 52 on the shank of bolt 44, passed through the bore 42 until the end of the locking bolt projects into the recess 18.
  • the plug 24 is threaded onto the end of the locking bolt 44 so as to be loose in the recess 18, and the bolt 10 is now ready for use.
  • the bolt 44 is tightened so as to draw the plug 24 into the recess 18 to splay the segments between the slots 16 and to lock the bolt in position either against a bore in which it is threaded, or against a nut which is threaded onto the shank 14 of the bolt 10.
  • shank 14 is part of a bolt, it could comprise simply a threaded stud and this embodiment, as will be explained, is particularly suitable for use as a vehicle wheel stud.
  • the shank 14 will be threaded, in some instances a locking arrangement can be achieved without the shank being threaded, for example when the bolt acts in the nature of a fixing device in a hole in masonry building material (see the examples in Figs. 6 to 8) .
  • the main feature of the locking arrangement is that the included angle of the tapered recess 18 differs from the taper angle of the plug 24 so that the taper angle of the plug 24 is preferably slightly greater but may be slighlty less than that of the recess 18.
  • the taper angle of the recess 18 is 29° inclusive as shown, whilst in the case of the plug 24, the taper angle is 35°.
  • the taper of the plug 24 extends to the effective inner thread diameter of the threaded extension 22, as indicated by reference numeral 60.
  • the angle specified for the arrangement of Figs. 4 and 5 are for a specific bolt and plug size, and these angles may vary and the dimensions may vary depending upon the bolt size.
  • FIGs. 6 to 8 show embodiments of the invention as applied to masonry applications, wherein the devices are inserted into blind holes in building walls and the like. Consequently, the shanks in the devices of Figs. 6 to 8 are not threaded, as they are in the previous embodiments.
  • the devices do however operate on the same principle in that a plug is forced into a recess to provide a locking effect, and referring to Fig. 6 in detail, the device shown comprises a smooth shank 51 which is bored longitudinally to provide various bore sections (from left to right in the Fig.) as follows.
  • the tapering plug 68 forms the other part of the locking device and the plug 68 and recess 66 operate in the same manner as described herein in relation to the previous embodiments.
  • the plug 68 comprises a cylindrical portion 68a, which is slidably located in the bore portion 68, and the tapered portion 68b.
  • the plug is furthermore threaded on shank 64 of the cap screw 60, which has a lock washer 70 so that the cap screw will function similar to the lock washer described hereinbefore, and finally, a retaining disc 72 is attached to the end of the cap screw shank 64 to prevent detachment and possible loss of the plug 68.
  • slots 74 provided in the main shank 51 over the length of the shank 51 which spans the bore sections 66, 67, to function as hereinbefore described, and the plug 68 on its portion 68a or 68b or both has slender axial tongues which respectively slidably engage in the slots 74. These tongues prevent the plug 68 from turning in the shank as the device is being used.
  • the device is useable in a blind hole in masonry.
  • the device without the ring 54, is inserted into the hole, the plug 68 being generally loose in the recess 66, and the cap screw being loose in the bore in the shank 51, but having the plug threaded thereon.
  • the cap screw 64 is tightened by engaging an Allen key in the head of the cap screw 64 so that the plug 68 is pulled into the recess 66 as described hereinbefore, locking the device in the masonry hole.
  • the ring is screwed into the bore section 52 to provide the usual attachment means for scaffolding or the like.
  • the shank 51 is modified in that it has a flange 51a on the left hand end thereof, to enable the shank 51 to be removed from the masonry, and furthermore the bore in the shank 51 comprises only a plain section leading to the tapered and end sections 66, 67.
  • the plug 68 is essentially the same, but the scaffold retaining ring is replaced by a scaffold bolt 80, which passes through the shank 50 and has the plug 68 threaded thereon as shown.
  • the retaining disc 72 is attached to the end of the shank 82 of the scaffold bolt 80.
  • This embodiment operates in that the device is inserted into a hole in the masonry with the plug 68 loosely threaded on the bolt 80, and then the bolt is tightened to pull the plug 64 into the recess 66 providing the locking effect as described herein.
  • Fig. 8 shows yet another embodiment of a device for masonry application, but in this case the masonry ring bolt 90 which is used has the tapered plug 92 integrally provided at the end of the masonry bolt shank 94.
  • the bore 96 in the main shank 98 has the tapered portion 100 (defining the recess) extending in a narrowing sense in the direction towards the right hand end of the shank 98, which is the end which is inserted into the masonry hole.
  • the slots 102 are provided, but because the taper of each of the plug 92 and the recess 100 is towards the adjacent end of the shank 98, no retaining disc is needed.
  • FIG. 8 Operation of the device in Fig. 8 is particularly simple, in that the shank 98 is simply inserted into the masonry hole, with or without the masonry bolt therein, and then the bolt 90 is screwed into the shank 98, whose bore portion 96 is threaded for this purpose, so that the plug 92 is forced into the recess 100 to cause locking of the device as described hereinbefore. All of the masonry bolts of Figs. 6 to 8 are retrievable and reasonable.
  • Figs. 9, 10 and 11 show how the invention can be applied to vehicle wheel studs. It is a well recognised problem that in particular in relation to heavy vehicles such as lorries and buses, the self releasing of the wheel nuts is a serious problem.
  • the present invention in particular overcomes this problem, and furthermore in relation to this aspect of the invention, it is not necessary that the recess and plug angles differ, although clearly it is highly desirable.
  • the stud shown in Fig. 9 comprises the central shank portion 110 having a central flange 112 intermediate the ends thereof.
  • a threaded section 114 which screws into the wheel disk on which the stud is to be used, whilst to the right hand side or outer end is a threaded portion 116 which is provided with the recess 118 corresponding to recess 18 as hereinbefore described.
  • the axial slots 120 (corresponding to slots 16) are provided and the recess 118 leads to a threaded blind bore 122 to receive the threaded portion of the plug which will be essentially as shown in Fig. 5.
  • the stud portion 116 is in the order of 17 mm diameter, and the recess 118 has an included taper angle of 32°.
  • the plug for use with this stud preferably would have a taper angle in the order of 38°.
  • Fig. 10 shows an alternative arrangement for a vehicle wheel stud, and a main shank portion of 130 is provided with a straight narrowed sectioned 132 in the centre thereof, and at the left hand or inner end has a circular head 132 for stud retention on the wheel, but the threaded portion 136 at the right hand or outer end is provided with a recess 138 which is the same as recess 118. Again the slots 140 are provided. These slots typically are of the size of 1.25 mm for the particular stud illustrated.
  • Fig. 11 shows how the studs of Figs. 9 and 10 are used on a vehicle wheel of which the wheel disk is indicated by reference 140. Four studs 142 are shown and these are reference 142a to 142d.
  • Stud 142a is shown as ready to receive the locking plug 148, whilst studs 142b and 142c are shown with the studs 148 in position. Stud 142d is shown as having been provided with the wheel locking nut 150, and in order to use the studs and plugs 142/148, the plugs 148 may initially be disconnected from the studs or may be loosely fitted therein. The wheel is then placed over the studs and the nuts 150 are tightened in the normal manner.
  • the angle differentiation between the recess 18 and the plug 24 applies in all embodiments of the invention, and when a spring locking washer such as 38 and especially locking washer 52 is utilized, enhanced spring locking is achieved.
  • the locking washer adds tension to the bolt in order to keep the bolt under tension when in use, which decreases the likelihood that the plug will become loose when subjected to vibration.
  • the angles of the recess and plug may be varied depending upon shank diameter.
  • the taper angle of the plug may be of the order of 6° greater or less than that of the recess but this is not intended to be limiting of the general principle of the invention. It will be appreciated that in the embodiments described, whilst the bolts can satisfactorily be locked in position by the means described, they can also be released by loosening of the locking screw arrangements.
  • the end of the shank provided with the recess need not be slotted as indicated, but more or less radial slots could be provided or other weakening could be provided to ensure the splaying of the end. In some cases it may not be necessary to slot or weaken the end other than forming the insert therein.
  • the recess could taper in a narrowing sense, towards the end of the shank, as in the Fig. 7 embodiment.
  • the plug may be forced in by other axial loading and the tongues on the plug which locate in the slots may be used in all embodiments.
  • each stud is constructed for example as indicated in Fig. 1 hereof.
  • the studs will not have a hexagonal head, but will be fixed by suitable means to the wheel disc to which the wheel proper is fixed. Fixing of the wheel is effected by placing the wheel on the disc, with the studs projecting therethrough, and then the fixing nuts are screwed to the threaded, projecting stud shanks 14, to tighten the wheel to the disc, and then the locking plugs 24 are screwed into the stud shanks 14, locking the wheel securely to the wheel disc.
  • This adaptation of the invention is particularly suitable for heavy vehicles such as buses and trucks.
