Description

L'invention est relative à un dispositif de sécurité et de secours pour tapis roulant de montagne.The invention relates to a safety and emergency device for mountain treadmill.

Les tapis roulants de montagne sont destinés aux transferts de personnes ou de skieurs, entre un poste de départ ou d'embarquement et un poste d'arrivée ou de débarquement.Mountain treadmills are intended for the transfer of persons or skiers between a departure or embarkation station and an arrival or departure station.

Ces tapis roulants sont notamment utiles dans les stations de ski ou de montagne pour le transfert de skieurs ou de piétons équipés de chaussures de ski ou de bottes de neige.These treadmills are particularly useful in ski or mountain resorts for the transfer of skiers or pedestrians equipped with ski boots or snow boots.

Du fait que ces appareils sont soumis aux intempéries, aux chutes de neige et au gel, leur fonctionnement doit satisfaire des normes de sécurités contraignantes, de manière à éviter tout risque d'accident de personne.Because these devices are subjected to bad weather, snowfall and frost, their operation must meet binding safety standards, so as to avoid any risk of accident.

En référence aux figures 1 à 4, les éléments identiques ou fonctionnellement équivalents sont repérés par des chiffres de référence identiques.With reference to Figures 1 to 4 identical or functionally equivalent elements are identified by identical reference numerals.

Sur la figure 1, un dispositif (1) selon l'invention est disposé à l'extrémité d'un ensemble (2) de tapis roulant.On the figure 1 , a device (1) according to the invention is disposed at the end of a set (2) treadmill.

L'ensemble (2) de tapis roulant comporte de manière connue un caisson (2a) portant deux trottoirs (2b, 2c) et une bande transporteuse (2d).The treadmill assembly (2) comprises in a known way a box (2a) carrying two sidewalks (2b, 2c) and a conveyor belt (2d).

Le dispositif (1) selon l'invention ce présente sous forme d'un coffre (3) formant puits de secours, à volet coulissant (4) dans deux guides latéraux (5a, 5b) et un panneau d'ouverture (6).The device (1) according to the invention is in the form of a chest (3) forming a relief well, sliding shutter (4) in two lateral guides (5a, 5b) and an opening panel (6).

Le dispositif est muni d'une lame frontale (7) solidaire du volet coulissant (4).The device is provided with a front blade (7) integral with the sliding shutter (4).

Lorsqu'un utilisateur du tapis roulant circule dans le sens de la flèche A, son passage est détecté par une première paire de cellules photoélectriques (8) formant une barrière photoélectrique et éventuellement par une deuxième paire de cellules photoélectriques (9) formant barrière photoélectrique.When a user of the conveyor belt moves in the direction of the arrow A, its passage is detected by a first pair of photocells (8) forming a photoelectric barrier and possibly by a second pair of photocells (9) forming a photoelectric barrier.

Si un obstacle ou un utilisateur du tapis roulant exerce dans son déplacement une force sur la lame frontale (7) sensible à la pression ou reste détecté simultanément par les barrières photoélectriques (8 et 9) pendant un intervalle de temps prédéterminé, une commande motorisée ouvre le volet coulissant (4) pour éviter le coincement d'un bras ou d'un membre ou d'un vêtement de l'utilisateur.If an obstacle or a user of the treadmill exerts a force on the pressure-sensitive front blade (7) or remains simultaneously detected by the light barriers (8 and 9) for a predetermined period of time, a motorized control opens the sliding shutter (4) to prevent jamming of an arm or a limb or a garment of the user.

Le volet coulissant (4) est alors entrainé dans le sens de la flèche par une commande motorisée non représentée en détail, de sorte que l'espace compris entre la bande transporteuse (2d) la lame frontale (7) s'agrandit à une vitesse compatible avec celle de la bande transporteuse (2d).The sliding flap (4) is then driven in the direction of the arrow by a motorized control not shown in detail, so that the space between the conveyor belt (2d) the front blade (7) expands at a speed compatible with that of the conveyor belt (2d).

Le recul du volet coulissant (4) s'effectue jusqu'à la position correspondant à la figure 2.The sliding shutter (4) is retracted until the position corresponding to the figure 2 .

Sur la figure 2, l'ouverture dégagée par le volet roulant (4) est entièrement dégagée.On the figure 2 , the opening released by the shutter (4) is completely cleared.

La bande transporteuse (2d) est immobilisée à l'arrêt, tant que le volet coulissant (4) n'a pas retrouvé sa position de fermeture.The conveyor belt (2d) is immobilized at a standstill, as long as the sliding shutter (4) has not returned to its closed position.

L'accès au puits intérieur du coffre (3) permet de dégager tout objet ou toute personne ayant été happée par l'angle rentrant de la bande transporteuse (2d).Access to the inner well of the trunk (3) allows to clear any object or person who has been caught by the incoming angle of the conveyor belt (2d).

La largeur de l'ouverture est supérieure à celle de la bande transporteuse (2d) tandis que la longueur de l'ouverture est fonction de la distance d'arrêt du tapis roulant, cette longueur étant déterminée pour éviter une décélération trop forte qui pourrait faire tomber un passager ou un utilisateur du tapis roulant.The width of the opening is greater than that of the conveyor belt (2d) while the length of the opening is a function of the stopping distance of the conveyor belt, this length being determined to avoid an excessive deceleration which could make to fall a passenger or a user of the treadmill.

Selon l'invention, le volet coulissant (4) est un volet coulissant motorisé dont le déplacement en translation est commandé par les barrières photoélectriques (8 et 9), ou par une pression ou une force exercée sur la lame de contact (7), ou encore par une action volontaire d'un opérateur.According to the invention, the sliding shutter (4) is a motorized sliding shutter whose displacement in translation is controlled by the photoelectric barriers (8 and 9), or by a pressure or a force exerted on the contact blade (7), or by a voluntary action of an operator.

En effet, l'avantage d'un volet coulissant motorisé est de pouvoir ouvrir et fermer à distance ce volet roulant motorisé lorsque la bande transporteuse (2d) ne transporte pas d'utilisateur ou de passager. Notamment, en cas de mise en service ou en cas d'arrêt, le bon fonctionnement du volet coulissant peut être testé par un opérateur.Indeed, the advantage of a motorized sliding shutter is to be able to open and close remotely this motorized roller shutter when the conveyor belt (2d) does not transport a user or passenger. In particular, in case of commissioning or in the event of a shutdown, the smooth operation of the sliding shutter can be tested by an operator.

Egalement, dans le cas d'un enneigement important, l'ouverture et la fermeture du volet coulissant permet d'obtenir un déneigement automatique de l'extrémité de la bande transporteuse (2d).Also, in the case of heavy snow, the opening and closing of the sliding shutter provides automatic snow removal of the end of the conveyor belt (2d).

La commande par action d'un opérateur peut également être remplacée par une commande automatique couplée avec les cycles de fonctionnement du tapis roulant (2).The operator action control can also be replaced by an automatic control coupled with the running cycles of the treadmill (2).

Enfin, le coulissement en translation du volet roulant permet de réduire au minimum l'espace compris entre la lame de contact (7) et l'angle rentrant de la bande transporteuse (2d).Finally, the translational sliding of the roller shutter makes it possible to minimize the space between the contact blade (7) and the re-entrant angle of the conveyor belt (2d).

Sur la figure 3, un mode de réalisation préféré de dispositif selon l'invention comporte un actionneur tubulaire destiné à entrainer un tube (10) d'enroulement du volet coulissant (4).On the figure 3 , a preferred embodiment of the device according to the invention comprises a tubular actuator for driving a tube (10) for winding the sliding flap (4).

L'actionneur tubulaire comporte généralement un motoréducteur non représenté inséré à l'intérieur du tube d'enroulement (10).The tubular actuator generally comprises a not shown gear motor inserted inside the winding tube (10).

Le volet coulissant (4) peut être constitué sous forme de volet sectionnel ou de volet continu.The sliding flap (4) can be formed as a sectional flap or continuous flap.

La lame frontale de contact (7) définit l'extrémité d'enroulement du volet (4).The front contact blade (7) defines the winding end of the flap (4).

La configuration de la figure 3 correspond à une ouverture du volet coulissant (4) et à une possibilité d'intervention de secours à l'intérieur du puits défini par le coffre (3).The configuration of the figure 3 corresponds to an opening of the sliding shutter (4) and to a possibility of emergency intervention inside the well defined by the trunk (3).

Cette position ouverte correspond également, à un déneigement automatique avant la mise en marche de la bande transporteuse (2d).This open position also corresponds to automatic snow removal before starting the conveyor belt (2d).

Après déneigement, la bande transporteuse (2d) qui est guidée par le rouleau ou le tambour d'entrainement (11) est mise en marche selon le sens de la flèche A.After snow removal, the conveyor belt (2d) which is guided by the roller or the driving drum (11) is started in the direction of the arrow A.

Après avoir effectué le déneigement ou l'intervention de secours, le moteur ou actionneur tubulaire peut être commandé en sens inverse, de manière à dérouler le volet coulissant (4) dans les guides (5a, 5b) jusqu'à la position de fermeture représenté à la figure 4.After carrying out the snow removal or the emergency intervention, the tubular motor or actuator can be controlled in the opposite direction, so as to unroll the sliding flap (4) in the guides (5a, 5b) to the closed position shown. to the figure 4 .

Sur la figure 4, le volet coulissant (4) engagé dans les guides latéraux (5a, 5b) est en position de fermeture avec sa lame frontale (7) formant capteur de pression au contact de la bande transporteuse (2d).On the figure 4 , the sliding flap (4) engaged in the lateral guides (5a, 5b) is in the closed position with its front blade (7) forming a pressure sensor in contact with the conveyor belt (2d).

L'espace intérieur au dispositif est ainsi totalement clos et la bande transporteuse (2d) peut être commandé dans le sens d'avancement correspondant à la flèche A.The interior space of the device is thus completely closed and the conveyor belt (2d) can be controlled in the direction of travel corresponding to arrow A.

Si les barrières photoélectriques (8 et 9) sont obturées simultanément au-delà d'un intervalle de temps prédéterminé, la commande d'arrêt transmise à la bande transporteuse (2d) et la commande d'ouverture est transmise à l'actionneur tubulaire du tube d'enroulement (10), de manière à provoquer l'ouverture du dispositif et l'enroulement du volet coulissant (4).If the photoelectric barriers (8 and 9) are closed simultaneously over a predetermined time interval, the stop command transmitted to the conveyor belt (2d) and the opening command is transmitted to the tubular actuator of the winding tube (10), so as to cause the opening of the device and the winding of the sliding flap (4).

La même opération est effectuée si un contact de pression supérieur à un seuil prédéterminé est ressenti par la lame de contact (7) solidaire de l'extrémité du volet coulissant (4).The same operation is performed if a pressure contact greater than a predetermined threshold is felt by the contact blade (7) integral with the end of the sliding flap (4).

Enfin, un cycle de démarrage peut-être prévu qui correspond à une légère ouverture du volet coulissant (4) pour faciliter l'évacuation de la neige, puis un démarrage de la bande transporteuse (2d), puis une fermeture du volet coulissant (4) de manière à rapprocher la lame de contact (7) de la bande transporteuse ( 2d) en mouvement selon le sens de la flèche A.Finally, a start cycle may be provided which corresponds to a slight opening of the sliding shutter (4) to facilitate the evacuation of the snow, then a start of the conveyor belt (2d), then a closure of the sliding shutter (4). ) so as to bring the contact blade (7) of the moving conveyor belt (2d) in the direction of the arrow A.

Un moyen d'arrêt d'urgence non représenté peut également être prévu sur ou au voisinage du dispositif selon l'invention.An emergency stop means not shown can also be provided on or in the vicinity of the device according to the invention.

Enfin, le dispositif selon l'invention peut également être associé à des moyens de visualisation à distance, compatibles avec une commande à distance permettant une remise en route de la bande transporteuse (2d) dès fermeture du volet coulissant (4), et ce après résolution d'un incident mineur ne nécessitant pas d'intervention humaine ou de déplacement sur site.Finally, the device according to the invention can also be associated with remote viewing means, compatible with a remote control for restarting the conveyor belt (2d) as soon as the sliding shutter (4) is closed, and this after resolution of a minor incident that does not require human intervention or on-site travel.

L'invention décrite en référence à des modes de réalisation particuliers n'y est nullement limitée, et couvre au contraire toutes modifications de forme et toutes variantes de réalisations dans le cadre et l'esprit de l'invention.The invention described with reference to particular embodiments is not limited thereto, and on the contrary covers all modifications of form and all variants of embodiments within the scope and spirit of the invention.

Ainsi le tube d'enroulement (10) peut-être remplacé par tout autre moyen apte à déplacer le volet coulissant (4), par exemple un actionneur linéaire, un moteur linéaire, ou tout autre moteur ou moyen d'entrainement susceptible de générer un déplacement du volet coulissant (4) dans ses guides (5a, 5b).Thus the winding tube (10) can be replaced by any other means able to move the sliding flap (4), for example a linear actuator, a linear motor, or any other motor or drive means capable of generating a moving the sliding shutter (4) in its guides (5a, 5b).
