Description

La présente invention concerne un dispositif de protection d'un appareil destiné à être placé dans le sol, notamment de protection d'un appareil d'arrosage automatique.The present invention relates to a device for protecting an apparatus intended to be placed in the ground, in particular for protecting an automatic watering apparatus.

Il est courant d'installer des appareils d'arrosage automatique dans le sol (arroseurs escamotables). Lors du fonctionnement de ces appareils, une buse se soulève au-dessus du sol et diffuse de l'eau sur le sol. A ce moment là, cette buse est très vulnérable au vandalisme. En effet, il a pu être relevé le changement, au cours d'une année, de cinq cents buses le long d'une voie de tramway en comprenant deux mille. Indépendamment de ce problème de vandalisme, les arroseurs installés le long des voiries peuvent subir des écrasements lors du passage de véhicules dans les espaces verts. Il existe des systèmes de protections constitués d'une émergence au-dessus de l'arroseur. Mais elles constituent un obstacle dangereux pour l'entretien des espaces verts en particuliers les tondeuses et les piétons.It is common to install automatic irrigation devices in the ground (retractable sprinklers). During the operation of these devices, a nozzle lifts above the ground and diffuses water on the ground. At this moment, this nozzle is very vulnerable to vandalism. Indeed, it has been possible to note the change, during one year, of five hundred nozzles along a streetcar track including two thousand. Regardless of this vandalism problem, sprinklers installed along roadways can be crushed when vehicles pass through green spaces. There are protection systems consisting of an emergence above the sprinkler. But they are a dangerous obstacle to the maintenance of green spaces, especially lawnmowers and pedestrians.

Le document US 4,624,412 décrit un dispositif de protection d'un appareil d'arrosage automatique destiné à être placé dans le sol, comprenant :

  • une première partie délimitant intérieurement un logement, destinée à être placée dans le sol ;
  • une deuxième partie placée dans ladite première partie, délimitant elle-même un logement destiné à contenir l'appareil, cette deuxième partie étant mobile par rapport à la première partie entre une position de rétraction, dans laquelle une première extrémité de cette deuxième partie se trouve au niveau d'une première extrémité de la première partie, et une position de sortie, dans laquelle cette première extrémité fait saillie par rapport à ladite première extrémité de la première partie ;
  • des moyens de maintien, maintenant normalement ladite deuxième partie en position de rétraction ;
  • une chambre que délimitent lesdites première et deuxième parties, et
  • une conduite d'alimentation de l'appareil en liquide d'arrosage.
The document US 4,624,412 discloses a device for protecting an automatic watering apparatus for placing in the ground, comprising:
  • a first portion internally defining a housing, intended to be placed in the ground;
  • a second part placed in said first part, delimiting itself a housing for containing the apparatus, this second part being movable with respect to the first part between a retracted position, in which a first end of this second part is located at a first end of the first portion, and an exit position, wherein said first end protrudes from said first end of the first portion;
  • holding means, now normally said second part in the retracted position;
  • a chamber delimited by said first and second parts, and
  • a supply line of the apparatus in liquid spraying.

L'alimentation de l'appareil en liquide d'arrosage sous pression provoque le déplacement de ladite deuxième partie en position de sortie.Feeding the apparatus with pressurized coolant causes said second portion to move to the exit position.

L'appareil de ce type a une structure relativement complexe et onéreuse à fabriquer. De plus, le fonctionnement de cet appareil n'est pas optimal lorsque l'alimentation en liquide d'arrosage cesse. Il en est également de même lors de l"alimentation en liquide en vue d'amener ladite deuxième partie en position sortie.The apparatus of this type has a relatively complex and expensive structure to manufacture. In addition, the operation of this device is not optimal when the supply of cooling liquid ceases. It is also the same during the supply of liquid to bring said second part in the extended position.

Les documents US 3,655,132 et US 4,781,327 décrivent des appareils similaires, ne remédiant pas à ces inconvénients.The documents US 3,655,132 and US 4,781,327 describe similar devices, not overcoming these disadvantages.

La présente invention vise à remédier à l'ensemble de ces inconvénients.The present invention aims to remedy all of these disadvantages.

À cet effet, dans le dispositif qu'elle concerne,

  • lesdites première et deuxième parties sont de forme générale tubulaire, ladite deuxième partie étant placée dans ladite première partie, et
  • ladite deuxième partie présente une collerette définissant un alésage ajusté à un corps cylindrique que comprend l'appareil et est équipée, au niveau de cet alésage, d'un joint coulissant le long de ce corps cylindrique lors du mouvement de ladite deuxième partie par rapport à ladite première partie, cette collerette délimitant ladite chambre avec une paroi périphérique que comprend ladite première partie et avec un fond que comprend également cette première partie.
For this purpose, in the device concerned,
  • said first and second parts are generally tubular in shape, said second part being placed in said first part, and
  • said second portion has a flange defining a bore fitted to a cylindrical body that comprises the apparatus and is equipped at this bore with a sliding joint along said cylindrical body upon movement of said second portion relative to said first portion, this collar delimiting said chamber with a peripheral wall that comprises said first portion and with a bottom that also comprises this first portion.

Lesdits moyens de maintien peuvent notamment être constitués par un ressort hélicoïdal interposé entre des surfaces d'appui respectives que comprennent lesdites première et deuxième parties.Said holding means may in particular be constituted by a helical spring interposed between respective bearing surfaces that comprise said first and second parts.

De préférence, le dispositif comprend un raccord tubulaire reliant directement l'appareil audit fond que comprend ladite première partie.Preferably, the device comprises a tubular connection directly connecting the device to said bottom that comprises said first part.

Le montage de l'appareil dans le dispositif est ainsi réalisé de manière simple, uniquement par ce raccord.The mounting of the device in the device is thus achieved in a simple manner, only by this connection.

Selon une forme de réalisation préférée de l'invention, le dispositif comprend une arrivée de liquide sous pression dans ladite chambre, distincte de la conduite d'alimentation de l'appareil en liquide d'arrosage et reliée à cette conduite, le liquide sous pression alimenté dans ladite chambre par cette arrivée constituant des moyens d'actionnement permettant d'amener ladite deuxième partie en position de sortie, et des moyens d'échappement permettant, lorsque l'alimentation en liquide cesse, l'échappement du liquide hors de cette chambre puis son écoulement par l'appareil.According to a preferred embodiment of the invention, the device comprises a liquid inlet under pressure in said chamber, distinct from the supply pipe of the apparatus in cooling liquid and connected to this pipe, the liquid under pressure. fed into said chamber by this inlet constituting actuating means for bringing said second part into the output position, and exhaust means allowing, when the liquid supply ceases, the escape of the liquid from this chamber then its flow through the device.

Lorsque l'alimentation en liquide cesse, l'échappement de ce liquide se fait ainsi par l'appareil.When the supply of liquid ceases, the escape of this liquid is thus done by the apparatus.

Avantageusement, ladite deuxième partie forme, à une deuxième extrémité opposée à ladite première extrémité, une collerette venant, en position de rétraction, en recouvrement total ou partiel de l'orifice par lequel ladite arrivée de liquide sous pression dans la chambre débouche dans cette chambre.Advantageously, said second part forms, at a second end opposite to said first end, a flange coming, in the retracted position, in full or partial overlap of the orifice through which said inlet of liquid under pressure in the chamber opens into this chamber .

La venue de ladite deuxième partie en position sortie lors de l'alimentation de la chambre en fluide sous pression se réalise ainsi dans les meilleures conditions, le fluide portant contre cette collerette. De même, lors du retour en position de rétraction, cette collerette assure une évacuation complète du liquide présent dans la chambre.The coming of said second part in the extended position during the feeding of the chamber with fluid under pressure is thus carried out under the best conditions, the fluid bearing against this collar. Similarly, when returning to the retracted position, this flange ensures complete evacuation of the liquid present in the chamber.

Cette collerette présente une dimension telle qu'elle vient à proximité immédiate d'une paroi périphérique que comprend la première partie. Elle permet ainsi le guidage de la deuxième partie lors des mouvements de celle-ci. Elle est avantageusement équipée d'un joint assurant son étanchéité par rapport à cette paroi périphérique.This collar has a dimension such that it comes in the immediate vicinity of a peripheral wall that includes the first part. It thus allows the guiding of the second part during the movements thereof. It is advantageously equipped with a seal ensuring its tightness with respect to this peripheral wall.

L'invention sera bien comprise, et d'autres caractéristiques et avantages de celle-ci apparaîtront, en référence au dessin schématique annexé, représentant, à titre d'exemple non limitatif, une forme de réalisation préférée du dispositif de protection qu'elle concerne.

  • La figure 1 en est une vue en perspective, dans une position de rétraction ;
  • la figure 2 en est une vue en perspective similaire à la figure 1, dans une position de sortie ;
  • la figure 3 en est une vue en coupe longitudinale passant par l'axe de ce dispositif, dans la position de rétraction, et
  • la figure 4 en est une vue similaire à la figure 2, dans la position de sortie.
The invention will be better understood, and other features and advantages thereof will become apparent, with reference to the appended schematic drawing, showing, by way of non-limiting example, a preferred embodiment of the protective device that it relates. .
  • The figure 1 is a perspective view in a retracted position;
  • the figure 2 is a perspective view similar to the figure 1 in an exit position;
  • the figure 3 is a longitudinal sectional view through the axis of this device, in the retracted position, and
  • the figure 4 is a view similar to the figure 2 , in the exit position.

Les figures 1 à 4 représentent un dispositif 1 destiné à protéger un appareil 100 d'arrosage automatique, comprenant une première partie 2 délimitant un logement et une deuxième partie 3 placée dans le logement délimité par la première partie 2 avec possibilité de déplacement entre la position de rétraction montrée sur les figures 1 et 3 et la position de sortie montrée sur les figures 2 et 4.The Figures 1 to 4 represent a device 1 intended to protect an automatic watering apparatus 100, comprising a first part 2 delimiting a housing and a second part 3 placed in the housing delimited by the first part 2 with the possibility of displacement between the retracted position shown on the figures 1 and 3 and the exit position shown on the figures 2 and 4 .

La première partie 2 est destinée à être fixée au sol ou à un support placé dans le sol de telle sorte que son extrémité supérieure affleure avec la surface du sol. Elle est formée par un corps tubulaire 5, deux flasques 6 placés sur les extrémités de ce corps tubulaire 5 et des tirants périphériques 7 de maintien des deux flasques 6 contre les extrémités du corps 5.The first part 2 is intended to be fixed to the ground or a support placed in the ground so that its upper end is flush with the surface of the ground. It is formed by a tubular body 5, two flanges 6 placed on the ends of this tubular body 5 and peripheral tie rods 7 for holding the two flanges 6 against the ends of the body 5.

Les deux flasques 6 comprennent, sur un même côté, des trous 8 permettant le montage du dispositif 1 sur ledit support placé dans le sol.The two flanges 6 comprise, on the same side, holes 8 for mounting the device 1 on said support placed in the ground.

Le flasque 6 supérieur forme une paroi tubulaire 9 permettant le guidage de la deuxième partie 3.The upper flange 6 forms a tubular wall 9 for guiding the second part 3.

Le flasque 6 inférieur comprend un trou axial de raccordement d'une conduite 101 d'alimentation de l'appareil 100 en eau et un trou latéral de raccordement d'une conduite 102 d'alimentation d'une chambre inférieure 10 formée par les parties 2 et 3 l'une avec l'autre. La conduite 102 est reliée à la conduite 101.The lower flange 6 comprises an axial hole for connecting a pipe 101 for supplying the apparatus 100 with water and a lateral hole for connecting a pipe 102 for supplying a lower chamber 10. formed by parts 2 and 3 with each other. The pipe 102 is connected to the pipe 101.

L'appareil 100 comprend un corps cylindrique 100a. Son extrémité inférieure est reliée directement au flasque 6 inférieur au moyen d'un raccord tubulaire 11 axial.The apparatus 100 comprises a cylindrical body 100a. Its lower end is connected directly to the lower flange 6 by means of an axial tubular connection 11.

Comme le montrent plus particulièrement les figures 3 et 4, la deuxième partie 3 est formée par un corps tubulaire 15 et par un couvercle supérieur 16.As shown more particularly by Figures 3 and 4 the second part 3 is formed by a tubular body 15 and an upper cover 16.

Le corps tubulaire 15 forme une collerette intérieure 17 de montage de l'appareil 100, une collerette inférieure 18 dont le bord périphérique vient à proximité immédiate de la paroi du corps tubulaire 5, et quatre fenêtres supérieures 19 situées en regard de la buse 103 de l'appareil 100.The tubular body 15 forms an inner flange 17 for mounting the apparatus 100, a lower flange 18 whose peripheral edge comes in immediate proximity to the wall of the tubular body 5, and four upper windows 19 located opposite the nozzle 103 of the apparatus 100.

La collerette 17 définit un alésage ajusté au corps cylindrique 100a de l'appareil 100 et est équipée, au niveau de cet alésage, d'un joint torique d'étanchéité 20 coulissant le long de ce corps cylindrique 100a lors du mouvement de la deuxième partie 3 par rapport à la première partie 2.The flange 17 defines a bore fitted to the cylindrical body 100a of the apparatus 100 and is equipped, at this bore, with an o-ring seal 20 sliding along the cylindrical body 100a during the movement of the second part. 3 compared to the first part 2.

La collerette 18 est située à l'extrémité inférieure de la deuxième partie 3. En position de rétraction (cf. figure 3), elle vient en recouvrement partiel de l'orifice par lequel la conduite 102 débouche dans ladite chambre inférieure 10. Cette collerette 18 présente une dimension telle qu'elle vient à proximité immédiate de la paroi du corps 5, assurant, avec la collerette 17, le guidage de la deuxième partie 3 lors de ses mouvements. Elle est équipée d'un joint 20 assurant son étanchéité par rapport au corps 5.The flange 18 is located at the lower end of the second portion 3. In the retracted position (cf. figure 3 ), it comes partially covering the orifice through which the pipe 102 opens into said lower chamber 10. This collar 18 has a dimension such that it comes in the immediate vicinity of the wall of the body 5, ensuring, with the flange 17 guiding the second part 3 during its movements. It is equipped with a seal 20 ensuring its tightness with respect to the body 5.

Le corps 15, la collerette intérieure 17 et la collerette inférieure 18 délimitent, avec le corps 5 et les flasques 6, la chambre inférieure 10, laquelle est étanche à l'eau alimentée en elle par la conduite 102.The body 15, the inner collar 17 and the lower flange 18 delimit, with the body 5 and the flanges 6, the lower chamber 10, which is watertight fed into it by the pipe 102.

Le couvercle 16 est engagé dans l'extrémité supérieure du corps 15 et comprend un rebord venant, en position de rétraction, recouvrir le bord de la paroi circulaire 9 du flasque supérieur 6.The cover 16 is engaged in the upper end of the body 15 and comprises a flange coming, in the retracted position, covering the edge of the circular wall 9 of the upper flange 6.

Le dispositif 1 comprend en outre un ressort 25 interposé entre le flasque 6 supérieur et la face supérieure de la collerette 18, qui maintien normalement ladite deuxième partie 3 en position de rétraction.The device 1 further comprises a spring 25 interposed between the upper flange 6 and the upper face of the flange 18, which normally holds said second portion 3 in the retracted position.

Dans cette position de rétraction (cf. figures 1 et 3), le ressort 25 maintient la collerette 18 à proximité du flasque inférieur 6, et le rebord périphérique du couvercle 16 vient recouvrir le bord supérieur de la paroi circulaire 9. Il apparaît sur la figure 3 que la collerette 18 se trouve en recouvrement partiel de l'orifice par lequel la conduite 102 débouche à l'intérieur de la chambre 10.In this position of retraction (cf. figures 1 and 3 ), the spring 25 holds the flange 18 near the lower flange 6, and the peripheral rim of the cover 16 covers the upper edge of the circular wall 9. It appears on the figure 3 that the flange 18 is partially covering the orifice through which the pipe 102 opens into the chamber 10.

Lorsque le dispositif 1 est alimenté en eau, de l'eau sous pression arrive simultanément dans les conduites 101 et 102, ce qui a pour effet d'alimenter la chambre 10 en eau sous pression, provoquant le déplacement de ladite deuxième partie 3 vers la position de sortie (cf. figures 2 et 4), à l'encontre de la force élastique du ressort 25, et le coulissement télescopique simultané de la buse 103.When the device 1 is supplied with water, water under pressure arrives simultaneously in the lines 101 and 102, which has the effect of supplying the chamber 10 with water under pressure, causing the displacement of said second part 3 towards the exit position (cf. figures 2 and 4 ), against the elastic force of the spring 25, and the simultaneous telescopic sliding of the nozzle 103.

Un arrosage peut alors être réalisé par l'appareil 100, au travers des fenêtres 19.Watering can then be achieved by the apparatus 100, through the windows 19.

Le déplacement de la deuxième partie 3 vers la position de sortie s'opère d'autant plus rapidement que l'eau sous pression arrivant par la conduite 102 porte immédiatement contre la collerette inférieure 18.The displacement of the second part 3 towards the exit position takes place more rapidly than the pressurized water coming through the pipe 102 bears immediately against the lower flange 18.

Dès que l'alimentation en eau sous pression cesse, le ressort 25 ramène ladite deuxième partie 3 en position de rétraction, l'eau présente dans la chambre 10 refluant par la conduite 102 dans la conduite 101 puis dans l'appareil 100.As soon as the pressurized water supply ceases, the spring 25 returns said second part 3 to the retracted position, the water present in the chamber 10 ebbing through the pipe 102 in the pipe 101 and then in the apparatus 100.

Comme cela apparaît de ce qui précède, l'invention fournit un dispositif de protection d'un appareil destiné à être placé dans le sol, notamment de protection d'un appareil d'arrosage automatique, présentant les avantages déterminants de protéger efficacement ledit appareil contre les actes de vandalisme et à l'égard d'un écrasement, de ne pas constituer, en position de rétraction, un obstacle faisant saillie du sol, d'avoir une structure relativement simple et peu onéreuse à fabriquer, et d'avoir un fonctionnement optimal.As can be seen from the foregoing, the invention provides a device for protecting an apparatus intended to be placed in the ground, in particular for protecting an automatic watering apparatus, having the decisive advantages of effectively protecting said apparatus against acts of vandalism and with regard to a crushing, not to constitute, in retracted position, an obstacle protruding from the ground, to have a relatively simple structure and inexpensive to manufacture, and to have a functioning optimal.

L'invention a été décrite ci-dessus en référence à une forme de réalisation donnée à titre de pur exemple. Il va de soi qu'elle n'est pas limitée à cette forme de réalisation mais qu'elle s'étend à toutes les formes de réalisations couvertes par les revendications ci-annexées.The invention has been described above with reference to a given embodiment as a pure example.
