Detailed description of drawings
The invention will now be explained with reference to the following non-limiting drawings, wherein;
Figure 1 shows a plan view of the shank with a cut-out section; Figure 2 is a cross-sectional view of the shank;
Figure 3 shows a sectional view of an embodiment of the invention; Figure 4 shows a locking device and shank; Figure 5 is a drawing of an embodiment of the shank; Figures 6 & 7 illustrate further detail of the locking device.
In the drawings, reference numeral 10 generally refers to a shank for a locking device in accordance with the invention and reference numeral 12 to the locking device.
The shank 10 for a locking device 12 includes an outer casing 14 and an inner member 16, the inner member 16 being substantially elongate and housed within a part of the outer casing 14. The outer casing 14 is rotatable relative the inner member 16 and is generally rotatable in a direction 18 counter to a direction of rotation 20 of a cutting or grinding tool (not shown) applied to interfere the integrity of the shank 10 or the locking device 12. In the embodiments shown in the drawings, the shank 10 includes a bearing 22 for aiding the rotation of the outer casing 14 relative the inner member 16.
The bearing 22 shown in the drawings is a ball bearing arrangement but it is to be appreciated from the specification that bearing may be in the form of fluid bearings, rolling element bearings and the like. Figure 3 shows the bearing in a caged bearing arrangement 24.
The bearings are typically interposed between the outer casing 14 and the inner member 16.
In an embodiment not shown in the drawings, the shank 10 includes a lubricant (not shown) between the outer casing 14 and inner member 16.
The outer casing 14 is substantially elongate and is typically in the form of a hollow elongate.
In a further embodiment not shown, the outer casing 14 is fixed and the inner member 16 is configured to rotate 18 relative the outer casing 14.
The outer casing 14 is manufactured from any suitable material such as steel, titanium, a composite and the like.
The inner member 16 is in the form of a rod and is manufactured from any suitable material, but is typically manufactured titanium.
Figure 4 shows yet another embodiment of the invention, wherein a locking device 12, including a bracket 26 shaped and dimensioned to be releasably attachable to at least a part of a container (not shown), a shank 10 receivable through an aperture 28 defined by a surface 30 of the bracket 26 and securing means 32 for securing the shank 10 relative the bracket 26. In the embodiment shown, the locking device 12 has 2 brackets 26 and the brackets 26 are typically U-brackets.
The brackets 26 include arms 34, a base 36 and a flange 38.
The arms 34 are configured to allow for releasable attachment to the container. In the embodiment shown in the drawings, the arms 34 are configured to be compressible towards one another, the direction of movement shown by arrow 40, thereby to allow for releasable attachment to the container. Typically, the arms 34 of the bracket 26 are configured to be releasably attachable to a closure means (not shown) of an access opening of a container. The closure means of the access opening of a container is generally an elongate member (not shown) that engages with one or more aspects of the container.
The shank 10 is a cylindrical elongate and include a tapered end 42. Furthermore, the shank 10 includes a first right hand threaded section 44 and a second left hand threaded section 46. The first threaded section 44 has a larger diameter relative the second threaded section 46.
The shank has a head 48. The head 48 is shaped and dimensioned to limit the path of the shank 10 through the apertures 28.
The securing means 32 includes a first nut 50 and a second nut 52. The first nut 50 has a larger bore diameter 51 relative the second nut bore diameter 53. The first nut 50 has a right handed thread 54 and the second nut 52 a left handed thread 56.
The first nut 50 is shaped and dimensioned to engage with the first threaded section 44 of the shank 10 and the second nut 52 is shaped and dimensioned to engage with the second threaded section 46 of the shank 10.
Typically, once the brackets 26 have been placed in the desired position on the closure means of the container and the shank 10 has been inserted through the apertures 16, the first nut 50 is advanced along the tapered end 42 of the shank 10, until the first nut 50 engages with the first threaded section 44 and comes to lie adjacent the bracket 26. Further advancement of the first nut 50 towards the bracket 26 causes compression 40 of the arms 34 of the bracket 26 and thereby allows for releasable attachment of the bracket 26 to the closure means of the container.
The second nut 52 is advanced along the second threaded section 46 of the shank 10 until it a position adjacent the first nut 50 is achieved. The position of the second nut 52 adjacent the first nut 50 typically discourages loosening of the first nut 50.
The first nut 50 defines further apertures 58 for receiving the retaining pin 60. The further apertures 58 are threaded 62.
The second nut 52 defines further apertures 64 for receiving the retaining pin 60.
The locking device 12 includes a spacer 66.
