Description

[0036] Specific embodiments of the invention are now described with reference to the accompanying drawings wherein:

[0037] FIG. 1 illustrates a conventional utensil which has been adapted for use as an offensive weapon following removal of the utensil from a secure area;

[0038] FIG. 2 illustrates a utensil formed in accordance with an embodiment of the present invention;

[0039] FIG. 3 illustrates a cross-section along line A-A of the utensil of FIG. 2 in accordance with an embodiment of the present invention; and

[0040] FIG. 4 illustrates a secure area having a system implemented an a number of utensils provided in accordance with embodiments of the present invention.

[0041] Referring now firstly to FIG. 1, there is shown an example of a conventional utensil, formerly a standard plastic table knife A, which may be provided for use in secure locations or restricted environments such as prisons, post-security airport lounges or other secure facilities, and which may subsequently be taken and adapted for an ulterior use. In this case, and which is common in prisons and young offender facilities, the knife A can be adapted for use as an offensive weapon. This is a serious problem as discussed above. The present invention provides a utensil shown in one example as a table knife 1 in FIG. 2, which is provided for use within secure areas such as those described above. It will be understood that forks, spoons and other utensils for the preparation, serving and/or consumption of food and/or drink may also be formed in the same manner. The knife 1 is formed from a plastics or other polymeric material, and embedded within the plastics material, throughout the knife 1, there is provided a plurality of metal detectable and/or X-ray detectable material 3. The material 3 is provided such that if an attempt is made to remove the knife 1 from the secure area 5, detection apparatus 7 located at exits 9 from the secure area 5 will detect the presence of the knife 1, alerting security personnel and preventing removal of the knife 1 and any subsequent adaptation of the same for and ulterior/violent purpose. Thus, the invention serves to provide a utensil, shown in the figures as a knife 1, which may be used for its intended purpose and makes it particularly difficult to be taken, adapted/altered for use for another purpose, at least without detection upon attempted removal from the secure area 5. The secure area 5 may be any of a canteen, workshop, lounge area or other room within a larger building or environment for which security and/or safety is paramount, and removal of the utensil 1 from the secure area to another area needs to be prevented.

[0042] The level of metal detectable particles and/or X-ray detectable material 3 within the utensil 1 will be provided to be sufficient to ensure that the utensil 1, or at least a portion thereof will be detectable by metal detection and/or X-ray detection apparatus 7. The detection apparatus 7 provided will have known detection parameters such that only utensils 1 which are known to be detectable by the detection apparatus 7 will be made available in the secure area 5, thereby ensuring that the utensil Is or portions thereof are detected by the detection apparatus 7 which is in use at that time. Typically, the metal particles which are used and provided within the utensil 1 are ferrous metals or metal-compounds such as iron oxide derivatives, for example, magnetite (Fe.sub.2O.sub.3). The X-ray detectable material may be provided from iodine or barium derivatives, for example, barium sulphate (BaSO.sub.4). The metal detectable particles and/or X-ray detectable material is embedded throughout the utensil 1 such that after any attempt to shave, snap, cut, sharpen, reshape or otherwise alter the shape, size or appearance of the utensil 1, the metal detectable particles and/or X-ray detectable material will remain present within the altered form of the utensil 1, and thus be detectable by the detection apparatus 7, in use.

[0043] The utensil 1 forms part of a larger system provided to detect the attempted removal of such an item from a secure area 5. The system further includes the provision of the detection apparatus 7 located at one or more entrances to or exits 9 from the secure area 5. Thus, as any attempt is made to remove a utensil 1 from the secure area 5 by an unauthorised person 11, the utensil 1 is detected by the detection apparatus 7 once it is brought within range of detection 13 of the apparatus. Notification means are provided associated with the detection apparatus 7, such that in use, as a utensil 1 is attempted to be taken from the secure area 5, it will be detected and the apparatus will notify security personnel of the detection, enabling them to prevent the removal of the utensil 1 from the secure area 5. As mentioned above, the secure area 5 is provided to be a canteen, dining area, workshop or specific room or rooms in which the utensil 1 may be required to be utilised, within a prison, jail, penitentiary, or other such restricted location. In other embodiments of the invention, the secure area 5 may be provided to be within an airport location after the point where standard security checks are carried out.

[0044] The present invention therefore provides a means by which to detect the attempted removal of an item or items in the form of, for example, a standard utensil 1 from a secure area 5 to be taken into another area for an alternative use. The system is particular advantageous in that even if a degree of alteration or manipulation of the item or items is successfully achieved by a person 11 within the secure area 5, metal detectable particles and/or X-ray detectable material will still be present in a sufficient amount throughout the altered or manipulated utensil 1, to be detected by the detection apparatus 7 upon the attempted removal from the secure area 5 of that utensil 1. The present invention has particular use in, for example, a prison environment wherein standard culinary utensils may be attempted to be taken from a canteen or dining area to be reshaped into an offensive weapon for use in another area of the prison environmentthe present invention serves to prevent such instances from occurring and thus substantially reduce the occurrence of potentially violent incidents within that environment.
