Abstract

The end of course detector for a flexible swimming pool cover has inductive proximity sensors placed on the flexible straps (L) of the movable supports. The detection of the end of course is sensed by metal sensors (D) placed on the straps. The straps can be held in contact with the cover by a counterweight.

Description

Le systême de détection des fins de course est effectuè par deux détecteurs de proximité inductifs plaçés sur des lanières souples L ou support mobiles.The detection system of the limit switches is carried out by two inductive proximity sensors placed on flexible straps L or mobile support.

La détection de fin de course dans le sens couvrir la piscine (débobinnage du volet) est effectuée en détectant la présence métallique de l'axe A d'enroulement du volet une fois que celui-ci est déroulé ou en détectant la présence d'un élément métallique plaçé dans ou sur les dernières lames du volet.The end-of-travel detection in the direction of covering the pool (undrawling of the flap) is performed by detecting the metallic presence of the flap winding axis A once it has unwound or by detecting the presence of a flap. metallic element placed in or on the last blades of the shutter.

La détection de fin de course dans le sens découvrir la piscine (rembobinnage du volet) est effectuée en détectant la présence d'un élément métallique EM placé dans ou sur les premières lames du voletThe end of travel detection in the direction of discovering the pool (rewinding of the shutter) is performed by detecting the presence of an EM metal element placed in or on the first blades of the shutter

Un système de détection de fin de course pour volet de couverture de piscine flotant a été proposé dans le brevet US 5 524 302.A limit detection system for a floating pool cover flap has been proposed in US Patent 5,524,302.

Le système se caractérise par un ou des support(s) de détecteurs , qui sont souples ou mobiles afin d'appliquer le ou les détecteurs de fin de course sur le parcours de la couverture de piscine (couverture flottant sur la piscine). Les supports souples ou mobiles peuvent être placès dans ou hors de l'eau.The system is characterized by one or more sensor supports, which are flexible or movable to apply the one or more end detectors on the course of the pool cover (floating cover on the pool). Flexible or movable supports can be placed in or out of the water.

La figure illustre la détection de fin de course de couverture de la piscine lorsque le volet est complètement déroulé respectivement lorsque le volet est rembobiné.The figure illustrates the pool cover limit switch detection when the flap is fully unwound respectively when the flap is rewound.

Réalisation possible de l'invention :Possible realization of the invention:

Les détecteurs D de présence métallique sont placès sur des lanières souples L. Ces lanières sont maintenues en contact permanent avec le volet grâce à un contrepoids C.The metal presence detectors D are placed on flexible strips L. These strips are kept in constant contact with the shutter with a counterweight C.

La détection de fin de course du mouvement de couverture de la piscine est effective lorsque le volet étant tout déroulé , l'axe métallique A est détecté.The end-of-travel detection of the pool cover movement is effective when the shutter is all unrolled, the metal axis A is detected.

La détection de fin de course du mouvement de découvrement de la piscine est effective lorsque le volet étant pratiquement rembobiné, le métal EM contenu dans les lames de tête est détecté .The end of travel detection of the pool uncovering movement is effective when the flap is substantially rewound, the EM metal contained in the head blades is detected.

Les détecteurs utilisés ont un degré de protection IP67 ou IP68 selon la profondeur d'immersion .The detectors used have a degree of protection IP67 or IP68 depending on the immersion depth.

Claims (4)

  1. Immersed end-of-run detection system for a floating swimming pool cover shutter, comprising at least one metal detector (D) co-operating with at least one metal element (EM,A), said metal element being made of the metal winding axle (A) of said cover shutter or of a metal element (EM) belonging to the leading slats of said cover shutter, characterised in that said detector (D) is located on flexible straps (L), said straps being kept in permanent contact with said swimming pool cover shutter by a counterweight (C), said detector (D) detecting the end of the run in the unwinding direction of said cover shutter when it comes into contact with the metal winding axle (A), and detecting the end of the run in the winding direction of said cover shutter when it detects the presence of the metal element (EM) belonging to the leading slats of said cover.
  2. Immersed end-of-run detection system for a swimming pool cover shutter according to Claim 1, characterised in that said metal element (EM) is positioned in or on the last slats of said cover shutter.
  3. Immersed end-of-run detection system for a swimming pool cover shutter according to Claim 1, characterised in that said detection on said flexible straps (L) comprises at least two inductive proximity detectors.
  4. Immersed end-of-run detection system for a swimming pool cover shutter according to Claim 1, characterised in that said detectors (D) have an IP67 or IP68 protection level depending on the depth of immersion.
