Definitions
- the present invention relates to the field of protection against the intrusion of a perimeter by a barrier of infrared beams.
- Such barriers are well known in themselves. They consist of vertical elements or IR 20 columns arranged around of the perimeter and containing the emitters and IR beams regularly spaced vertically, which the receivers face r of the next column of the perimeter.
- Transmitters and receivers are arranged so that an intruder cannot cross the border perimeter without "cutting" at least one beam. For the receiver corresponding, the beam is obscured, and this occultation triggers an alarm.
- This last lower beam is necessarily placed very close from the ground, about 20 cm, to avoid crossing by crawling. This short distance makes untimely disturbances of the bundle by small animals, such as cats, rabbits or the like. In indeed these animals are big enough to set off an alarm even on sophisticated installations.
- a vertical obstacle at ground level so as to substantially replace the lower beam.
- This obstacle is arranged from the ground to a height below the second initial beam; its function is to oppose the crossing by crawling, and must also be high enough to deter small animals to cross it from above.
- An appropriate height is is around 40 cm.
- the barrier generally consists of columns 20 verticals with IR emitters on their sides and IR r receptors, in a known manner, as well as service 21.
- the whole delimits a section protective beam substantially represented at 22.
- Each element 1 consists of an element vertical 3 and a base 2. Openings 4 are provided in the vertical elements 3 to allow the free passage of small animals. It has been established that an opening of the order of 10 to 15 cm allows animals to circulate without being tempted by a crossing by the above. On the top of the vertical element 3, a harrow 5 or a set of tips designed to prevent birds from landing on the system. These tips can also be oriented according to several directions for better efficiency.
- the beam immediately upper 7 is naturally close enough to prevent any crawling.
- the elements are preferably assembled using spacers 8, advantageously made of stainless steel.
- the spacers 8 are extended in the mass of the elements, and at least at the level of the vertical obstacles, but preferably both in the vertical elements and in the base, by plastic sheaths 9 for the passage of cables 6. It will be especially the power cables for the columns. This represents another important advantage of the invention because the cables are both invisible and protected, and you can do without sleeves etc ... annexes.
- These passages 8, 9 will also be used to form tamper ports, i.e. triggering an alarm in the event of deterioration (for example during an attempted deterioration of the low wall).
- the invention is not limited to the example given above.
- the invention on the contrary, also covers all the embodiments, various adaptations and variants which will be directly accessible at a person skilled in the art on reading the general principle and the example above.
- the low wall can be replaced by a grid or grid or similar, with openings 4.
- the harrow can be replaced by any system designed to dissuade birds from landing on the top of the wall or grid or grating or the like, as for example an electrified wire.
- You can also use on the top of the wall a double electrified wire, arranged so that the bird or other animal establishes contact by landing or resting on the wall, which triggers the electric shock.
- the openings 4 they can be placed on the ground and / or close to the ground.
- the invention applies to any type of anti-intrusion barrier for which poses the same problem.

Description
Claims (8)
- Barrière IR anti intrusion périmétrique, du type se composant d'éléments verticaux ou colonnes IR 20 disposées autour du périmètre à protéger et contenant les émetteurs e de faisceaux IR régulièrement espacés verticalement, auxquels font face les récepteurs r de la colonne suivante du périmètre, caractérisée en ce que on dispose un obstacle vertical 2 au niveau du sol de manière à sensiblement remplacer le faisceau IR inférieur, l'obstacle comportant des ouvertures 4 au sol ou proches du sol pour le passage des petits animaux.
- Barrière IR anti intrusion périmétrique selon la revendication 1, caractérisée en ce que sur le sommet de l'élément vertical 3, on place une herse 5 ou un ensemble de pointes, ou un fil électrifié, ou deux fils électrifiés disposés de telle sorte que l'oiseau ou autre animal établit le contact en se posant ou en prenant appui sur le muret.
- Barrière IR anti intrusion périmétrique selon la revendication 1 ou 2, caractérisée en ce que l'obstacle se compose d'éléments 1 modulaires.
- Barrière IR anti intrusion périmétrique selon l'une quelconque des revendications 1 à 3, caractérisée en ce que chaque élément 1 selon l'invention se compose d'un élément vertical 3 et d'une base 2, la herse 5 ou le(s) fil(s) électrifié(s) étant disposés sur le sommet de chaque élément vertical 3.
- Barrière IR anti intrusion périmétrique selon la revendication 4, caractérisée en ce que les éléments verticaux 3 comportent des ouvertures 4 proches du sol ou au sol.
- Barrière IR anti intrusion périmétrique selon l'une quelconque des revendications 3 à 5, caractérisée en ce que les éléments modulaires 1 s'assemblent à l'aide d'entretoises 8.
- Barrière IR anti intrusion périmétrique selon la revendication 6, caractérisée en ce que les entretoises 8 sont prolongées dans la masse des éléments, et au moins au niveau des obstacles verticaux, mais de préférence aussi bien dans les éléments verticaux que dans la base, par des gaines plastiques 9 pour le passage de câbles 6 d'alimentation des colonnes et d'autoprotection.
- Eléments modulaires permettant de former un obstacle vertical pour barrière IR selon l'une quelconque des revendications 1 à 7, ces éléments étant tels que définis dans l'une quelconque des revendications 3 à 7.
