Definitions
- This invention relates to a locking device and in particular to a lockable, tamper- evident device for securing a closure member in its closed position to an article.
- the present invention overcomes the above problems by providing a cheap to produce and reliable, lockable device for which no separate tool is required for locking and/or unlocking purposes.
- the device provides a self-evident means for identifying when a closure member for an article., has been tampered with in order to gain access to the article. Once the device is in a locked-closed position it is only removable by means which result in physical damage to the device which in turn provides evidence of tamper. Furthermore, once the device has assumed the locked-closed position it is not re-usable. Thus, it may be more appropriate to refer to the lockable device as a security seal. Each seal is uniquely identifiable, for example, by a bar code or serial number or by other means which would be apparent to the skilled person. Accordingly, any attempted replacement of a broken seal with a new seal would be evident by comparison of the respective device identification means.
- the present invention provides a lockable tamper-evident device for securing a closure member in its closed position to an article, comprising a pair of arms which are movable between an open position in which the arms are engagable with an article and/or a closure member, and a locked-closed position in which disengagement of the arms from the article and/or the closure member is prevented by engagement of a cooperable locking means carried by the arms, activation of the locking means being brought about by movement of the arms to the locked-closed position, and when in the locked-closed position removal of the closure member being prevented by engagement of the arms with the article and/or the closure member.
- the arms are engagable with a projection extending either from the article and through an opening in the closure member or from the closure member and through an opening in the article.
- the projection may extend through an opening provided in an outwardly facing part of the article.
- the projection and the arms are adapted to engage with each other.
- the arms form a socket in the locked-closed position which is engagable with a ball located at the free end of the projection.
- the arms may carry inwardly facing edges which, in the locked-closed position, grip corresponding grooves located on the projection.
- the projection and the corresponding opening are of non-circular cross section to minimise potential rotation of the closure member about the projection.
- the present invention includes further means for engagement of the arms and the projection which would be apparent to the skilled person.
- the arms are simultaneously engagable, when in the open position, with two projections and when in the locked-closed position the cooperable locking means prevents disengagement of the arms from the two projections.
- each arm carries an outwardly extending portion, and when the arms are in the locked-closed position, the outwardly extending portions protrude in substantially opposite directions, and when the arms are in the open position, said portions are engagable with corresponding orifices located on facing surfaces of the two projections.
- the two projections have a pair of holes located in facing surfaces for engagement with the outwardly extending portions of the arms.
- the arms are hingeable and the outwardly extending portions protrude from the outer surface of each arm which is remote from the hinge.
- the arms are hingeable end-to-end and the outwardly extending- portions are located in close proximity to the hingeable ends of the arms.
- the distance between the respective free ends of the outwardly extending portions is greater in the locked-closed position than it is in the open position. This is achievable by way of the hingeable arrangement of the arms which is described below.
- the arms In the locked-closed position, the arms are substantially parallel to each other and the internal angle formed by the arms and the hinge is substantially zero.
- the free ends of the outwardly extending portions follow a defined radial path relative to the hinge.
- the free ends of the outwardly extending portions will be diametrically opposite each other at which point the distance between the free ends is a maximum.
- Further hinged movement increases the internal angle and simultaneously reduces the distance between the respective free ends of the arms until the arms reach the open position in which they are engagable with the two projections.
- the maximum internal angle between the arms is limited by abutment of the hingeable ends of the arms with each other.
- the maximum internal angle is generally restricted to less than 180° by cooperation of an abutment shoulder extending from the hingeable end of one arm with the hingeable end of the other arm. Restriction of the internal angle reduces undesirable stress on the hinge.
- One or both of the two projections may be slidably mountable to the article and/or the closure member.
- the outwardly extending portions are barbed so that, following engagement of the outwardly extending portions with the two projections, inadvertent disengagement of an outwardly extending portion from its projection does not occur as a result of slidable movement of the projection/s.
- An advantage of this embodiment is that the barbed portions automatically provide a tightening of the device and the article and/or the closure member during actuation of the arms from the open position to the locked-closed position by a relative drawing together of the two projections.
- one of the arms of the device has a line of weakness located between the locking means and the point of engagement of the arm with the projection, said line of weakness providing convenient means for removal of the device.
- Simple manual force for example fingers acting directly on the arm, is sufficient to break the arm and release the seal.
- the device is simultaneously engagable with a projection extending from the closure member and with a projection extending from the article.
- the closure member is preferably mountable to the article at a position away from the point of engagement of the device and the two projections.
- Figure 1 illustrates a plan view of one embodiment of the device according to the present invention in which the arms are in the open position and in which the arms are engagable with two projections.
- Figure 2 illustrates a plan view of the device as shown in figure 1 in which the arms are in the locked-closed position.
- Figure 3 illustrates a plan view of the device as shown in figure 2 in which one of the arms has been broken along a line of weakness to allow removal of the device.
- a pair of arms 1, 1' are mounted end-to-end by a hinge 2.
- the arms and hinge are formed as an integral plastics mounding.
- Each arm 1, 1' carries a curved outwardly extending portion 3,3' located on the outer surface 4,4' of each arm 1, 1' which is remote from the hinge 2.
- the arms 1, 1' are movable along a defined radial path relative to the hinge 2.
- the free ends 5,5' of the curved portions 3,3' are diametrically opposite each other. In this position, the distance between the respective free ends 5,5' is a maximum.
- any further increase of the internal angle, ⁇ , formed by the arms 1,1' and the hinge 2, reduces the distance between the respective free ends 5,5' of the curved portions 3,3' until an open position is achieved in which the curved portions 3,3' are engagable with a pair of openings 6,6' located in facing surfaces of a pair of corresponding projections 7,7', forming part of the article (not shown) to be secured.
- the projections 7,7' are of rectangular cross-section and extend through corresponding rectangular slots provided in the closure member (not shown). Only the free ends of the projections 7,7' are illustrated.
- a resiliently yieldable arrow-head formation 8 is located on the inside surface 9 of the arm 1. Hinged actuation of the arms 1, 1' (in the direction of the arrows) towards each other permits sliding insertion of the arrow-head formation 8 through a reduced diameter mouth 10 located on the facing inside surface 9' of the arm 1' and into a corresponding socket 11 located within the arm 1 '.
- the reduced diameter mouth 10 defines an inwardly facing abutment shoulder 12.
- the arm 1' carries a protective flange 13 along both opposite side surfaces (not shown) of the arm 1' (only one is shown). During actuation of the arms 1,1' to the locked- closed position, the flanges 13 slide over the corresponding opposite side surfaces (not shown) of the arm 1 and protect the arrow-head formation 8, the reduced diameter mouth 10, the abutment shoulder 12 and the socket 11 from tamper.
- Figure 1 also illustrates a single barb variant 14 which is inter-changeable with the arrow-head formation 8 on arm 1.
- the single barb 14 is slidingly inserted into, though not retractable from the corresponding reduced diameter mouth 15 located on the inside surface 9' of the arm 1'.
- the abutment shoulder 16 and the socket 17 function as described above for the shoulder 12 and the socket 11 respectively.
- An extension 18 of the hinged end 19' of the arm 1 ' provides an abutment surface 20.
- the surface 20 prevents excess hinged movement of the arms 1, 1' by abutment of the hinged end 19 of the arm 1 with the surface 20.
- the arms 1, 1' are in the locked-closed position.
- the barbed portions 3,3' are engaged with the projections 7,7' and the arrow-head formation 8 is non-retractably inserted into the socket 11 located in the arm 1 ' .
- a line of weakness 21 is located across the arm 1' between the barbed portion 3' and the socket 12.
- the arm 1' has been broken along the line of weakness 21, thereby allowing the barbed portions 3,3' to hinge towards each other to an open position in which they are releasable from the openings 6,6' of the projections 7,7'.
- the illustrated device is now broken, unusable and provides evidence of tamper. In practice, the device is only intended to be broken by authorised personnel.
