Definitions

  • DE 2802903 is a pneumatic system which does not detect minor longitudinal deformations.
  • FR 2603323 is an uninsulated mechanical/electrical system, current leakage thus being a possibility, and the bars can be cut using electrically-insulating materials (i.e. radial saw, cut-off torch, etc.) without being detected, and it has no continuity detection.
  • electrically-insulating materials i.e. radial saw, cut-off torch, etc.
  • FR 2566831 is a passive (mechanical) system with a revolving inner cylinder.
  • BE 879799 is a pneumatic/hydraulic system. It would not detect minor changes in the bars.
  • DE 2927926 is a hydraulic/mechanical system with a glass bulb which, when broken, modifies the pressure inside the structure.
  • DE 4318723 is a system with weakened bars and an uninsulated electrical system, it being possible for the bars to be cut without being detected.
  • EP 0073934 is a system based on the metal expansion and flexibility coefficient differential. This system may undergo have operating faults, depending on the temperature to which the fence or grille is subjected.
  • EP 0087076 is a system based on resistive variations, which, compared to ours, would give rise to faults with regard to occasional temperature-induced resistive variations.
  • GB 2098770 is a system based on optical fiber conductors with generators and receivers. This system would not detect the minor deformations, and the active elements would be subjected to major temperature changes, with the resulting damage thereto.
  • DE 3632111 is a vibration-detection system attachable to any metal structure. Compared to the system presented herein, this system has been found to generate false alarms due to impacts and does not detect cuts or curvatures in the structure.
  • US 4922228 is a fiber optics system which does not detect minor curvatures in the fence or grille.
  • IT 1126241 is a fluid pressure-based system and does not detect minor deformations.
  • DE 3503973 is a fluid pressure-based system and does not detect minor deformations.
  • DE 4337824 is a system containing a steel cylinder inside reinforcing the structure but does not detect deformations or cuts.
  • CN 1277308 is an electrical induction system which may cause false alarms resulting from sudden temperature changes or changes in the frequency generator.
  • GB 2194371 is a fiber optics wiring-based system. This system could not detect minor deformations.
  • EP 0118698 is a system based on internal photocells. This system would generate false alarms caused by temperature changes or high temperatures.
  • WO 9726517 is a fiber optics wiring-based system. This system could not detect minor deformations.
  • WO 9726517 is a fiber optics wiring-based system. This system could not detect minor deformations.
  • DE 3306002 is a system based on a light transmitter and receiver. This system would not detect minor deformations in the structure and would cause Faults generated by high temperatures.
  • the invention is a fence or grille housing a curvature detection system adapted to the needs of the customer, detecting, for example, from 3 mm, the deformation of the longitudinality of the bar and a cut detection system which detects said cut independently of whether made with metal material (saw), insulating material (abrasive discs) or gaseous material (cutting torches).
  • the tube forming the structure of the fence or grille may be either square, round, rectangular, pentagonal, with narrower or wider sections, etc. Any shape of tube or structure will be suitable, the use of sensors on the interior thereof being absolutely essential.
  • the metal structure of the fence or grille is to be hermetically sealed and is protected from rusting inside by means of the use of small deposits of mositure-proofing salts or the use of a dry-air circuit (i.e. with pressurizer) depending upon the intended use of each fence or grille.
  • the cut-off and curvature sensors are used for the purpose of detecting the deformations and cuts prior to full completion of these acts, ensuring the inviolability of said fences or grilles without being previously detected as such.
  • the cut-off sensor is to always be activated prior to cutting the bar, the structure of the fence or grille being protected and set to activate the alarm before the tampering is completed.
  • the curvature sensor shall be of a diameter which will depend upon the desired sensitivity thereof (i.e. with an inner diameter of 6 mm, the bars may deform up to 3 mm before activating the sensor).
  • the set of sensors works on minimum voltages and current strengths.
  • the set of sensors is insulated from the structure of the fence or grille by means of a Teflon support and encapsulated in heat-resistant insulating material. This structure is grounded to prevent accidental electrical shocks.
  • the sensors could be activated in all cases upon curving, it being important to stress that it is not necessary for the cutting to be done using metal tools. The cut-off will always be detected even when using tools of insulating material.
  • the wiring system necessary for the wiring of the different sensors to be installed are to be run through the inside of the fence or grille proper to any of the floor or wall-attachment pins through which it is decided to run the wiring.
  • the wires used are to be heat-resistant.
  • Cut-off sensor To be comprised of a cable insulated electrically from metal structure by means of an insulating casing made of fiberglass or any other insulating material which will withstand high temperatures, forming a continuous circuit. This sensor would operate in normally closed state (No. 9).
  • Curvature sensor To be comprised of a metallic tube (No. 5) of an inner diameter to be determined by the desired curvature sensitivity to be used. The ends of the tube have some heat-resistant, insulating material closures (No. 4), a metal wire running through said closures or caps through the center of the diameter of the tube and along the full length thereof (No. 7). A tightening spring is used at one of the ends of the sensor to keep the wire taut and uncurled. The entire assembly is encapsulated in insulating material (No. 6). The sensor fits up to the inner structure of the fence by means of insulating material supports installed a maximum of every 50 mm (No. 3).
