Definitions
- the invention relates to an arrangement for monitoring exhibit areas, in particular of exhibition tables and showcases which are to be monitored if an unauthorized person removes one Object triggers an alarm message.
- Light barriers are often used, which in the event of unauthorized approach to the exhibit to trigger an alarm.
- the object of the invention is to carry out an arrangement for monitoring exhibit areas in such a way that that it works in a wide range regardless of weight and the exhibits are largely freely positionable and no solution elements are attached to them have to.
- this object is achieved in that on the surface of the exhibit area distributed a plurality of holes are arranged in a grid. To those to be monitored A push pin is inserted into the hole under the exhibit, one Optical fiber deformed on an elastic base. The change in deformation at Removal of the exhibit is evaluated and an alarm message is issued.
- the pressure pin deforms when loaded by the Exhibit the fiber optic cable and when it is removed it is relieved.
- the pressure pin deforms when it is relieved by removal of the exhibit the optical fiber.
- the push pin acts via a spring-loaded rocker on the optical fiber.
- the rocker is a bearing block with a spring and a pressure pin / required deformation of the optical waveguide adapted lever arm.
- the pressure pin is designed to be resilient.
- the bearing surface of the pressure pin can be a pressure plate be enlarged.
- the optical waveguide is meandering under the bores of the exhibit surface. or laid spirally and the ends are with a light transmitter and light receiver connected to an evaluation unit.
- the arrangement is used to monitor exhibits at exhibitions in the exhibition areas, especially installed in exhibition tables and showcases as well as showcases.
- a large number of holes are distributed in a grid in the exhibit area arranged.
- the exhibition area can consist of a wide variety of materials and are composed of different layers.
- a wooden frame is useful with a decorative cover plate and a lower base plate.
- the exhibit surface of the arrangement according to the invention can be a decorative surface layer included that has no openings on delivery. Only before use are only through the holes in the cover plate, over which the exhibits to be monitored to be arranged, openings for the pressure pins pushed through. Already already used exhibit surfaces can have a new surface layer for other applications receive.
- the push pin should be springy. It is useful that the pressure pin itself contains a compression spring. The spring force and the spring travel must be with the elastic pad coordinated and be so large that this leads to an evaluable deformation of the optical waveguide lead without damaging it.
- the contact area of the pressure pin should be enlarged with a pressure plate.
- the optical fiber is meandering or spiral-shaped under the holes in the exhibit area laid and fixed.
- the ends of the optical fiber are with a light transmitter and light receiver connected to an evaluation unit.
- the elastic underlay is an elastically deformable, resilient mat that consists of different Materials exist and can be shaped differently.
- the arrangement can be armed / disarmed via a transponder.
- the optical waveguide 4 deformed when relieved by removing the exhibit 9.
- the pressure pin 1 acts via a spring-loaded rocker 2; 3 on the optical fiber 4.
- the seesaw is a bearing block 2 with a spring 3 and the pressure conditions between the pressure pin 1 and the required Deformation of the optical fiber 4 adapted lever arm.
- the correct deformation of the optical waveguide 4 is the right one Choice of the elasticity of the mat 5 is important.
- Fig. 1 the invention is shown in the operating state with an exhibit 9 to be secured.
- the exhibit table with a table top 7 and a decorative surface 8 has one Cavity between the table top 7 and the bottom 6 of the table top frame on the rockers from bearing block 2 with spring 3 for the individual push pins 1.
- Between the elastic arm 5 is on the lever arm of the rockers and the base 6 of which the optical waveguide 4 is arranged.
- the pressure pin 1 is determined by the weight of the exhibit 9 depressed against the spring force of the torsion spring 3.
- the arrangement according to the invention for monitoring exhibit areas works in one wide range regardless of weight. From a minimum weight there is practically no upper weight limit available for functionality. Is the counterforce of the compression spring overcome, the exhibit lies directly on the surface of the exhibit surface and can do not damage the optical fiber. The exhibits are within the selected grid freely positionable. No elements of the surveillance solution have to be attached to the exhibits become.
