(3) FIELD OF THE INVENTION This invention relates to attachment equipment employable for releasably attaching a device, that is formed against permitting its release by way of other techniques, to a carrier base against which it is firmly pulled up on achieving attachment via at least one attachment facility as extending from such carrier base and passing through an aperture in such device, against unauthorised removal though still permitting release of such device from its carrier base by means of appropriate conventional engaging and releasing equipment. Although not so limited the invention finds useful application in engaging wheels of which the rims are deeply recessed against unauthorised release to wheel drums.
(4) PRIOR ART DESCRIPTION AND DISCLOSURES Specially designed wheel nuts requiring uniquely designed wheel spanners have been proposed in overcoming the problem of unauthorized wheel removal. Although such
equipment certainly succeed in addressing the problem it has the disadvantage that loss thereof cannot be easily replaced as is the case with conventional wheel spanners.
(5) BRIEF DESCRIPTION OF THE DRAWING The invention is now described, by way of example, with reference to the accompanying drawings. In the drawings Figure 1 shows in unengaged three dimensional view attachment equipment, as manipulable by engaging and releasing equipment in the form of a wheel spanner, for releasably attaching a device in the form of a wheel against unauthorised removal to a carrier in the form of a hub, Figure 2 shows the equipment in coupled partly cut away three-dimensional view, Figure 3 shows the equipment in uncoupled side elevation also showing part of a wheel spanner and a wheel stud, Figure 4 shows in side elevation a fastener-manipulating member, forming part of the attachment equipment, in the form of an attachment adapter, Figure 5 shows the adapter in end view in the direction of arrow A in figure 4, and Figure 6 diagrammatically shows the equipment in operative use in securing a wheel against unauthorised removal to a wheel carrying drum.
(6) DETAILED DESCRIPTION OF THE DRAWINGS Referring to figures 1 to 5 of the drawings attachment equipment for releasably attaching a device in the form of a wheel against unauthorised removal to a carrier in the form of a wheel carrying drum, as manipulable by engaging and releasing equipment in the form of a conventional wheel spanner, is generally indicated by reference numeral 10.
The equipment 10 comprises a fastener in the form of a threadably engageable fastening stub 12 and a fastener manipulating member in the form of an attachment adapter 14 interspaceable between a stub 12 and a wheel spanner 16, not forming part of the equipment 10, for enabling the securing and releasing of a the stub 12 to a wheel stud, as extending from a hub, by means of the wheel spanner 16.
The fastening stub 12 is formed with a bore 18 that is threaded for a pre-established distance from the wheel stud engaging end 12.1 while the opposite end region of the bore 18 presents a non-standard multi-sided profiled socket 20. The length of threading is adequate to ensure that the stub 12 can be tightly engaged with a drum stud in operatively pulling a wheel up against its drum. To prevent engagement of the socket 20, as thus of non-standard multi-sided profile, by appropriate conventional engaging and releasing equipment such as a spanner carrying a conventionally profiled head, the socket 20 presents a heptagonal end profile. If will be appreciated that the socket 20 can have any other non-standard end profile to enable it to perform its uniquely engageable function.
The adapter 14 is thus formed to engage at its one end with the socket 20 of the stub 12 and be engaged at the opposite end by a wheel spanner 16. To this effect the end region 14.1 of the adapter 14 presents a socket engageable head 22 of matching heptagonal profile, as clearly shown in figure 5, to releasably engage the socket 20. The opposite end region 14.2 of the adapter 14 presents a head 24 of conventional hexagonal profile enabling its being engageable by the socket 16.1 of a conventional wheel spanner 16.
In also referring to figure 6 the equipment 10 is thus used to prevent unauthorised removal of a wheel 24, that is formed against permitting its release by way of other techniques, from its wheel carrying drum 26. The typical wheel that can be usefully fitted to its drum by way of one or more stubs 12 of the invention involves a rim 28 that is adequately deeply recessed from its side of drum engagement to limit access to a stub 12 engaging with a wheel stud 30.
Such deep recessing of the rim 28 results in the stub 12 being fully located within the recessed zone 32 of the rim 28 once fitted to a stud 30. Access to the stub 12 by, for example, a monkey wrench, in gripping its outside surface to unscrew it from its stub is limited by a lack of working space as brought about by the stub 12 fitting in a narrow annular
zone extending between the hub 34, as extending into the recessed zone 32, and the inner wall of the rim 28.
Replacement of one wheel nut by a fastener 12 of the invention results in engagement of such wheel 24 to its drum 26 against unauthorised romoval except with the use of the adapter 14.
In using an ordinary wheel spanner it is not necessary to carry any specialised wheel releasing equipment along, except for the adapter 14. While the fastener 14 is thus located against release except by way of the adapter 14, tho non-standard profiling of the socket 20 furthermore prevents the release of the stub 12 by other conventional rotation inducing equipment such as a tool presenting a hexagonal hoad.
