Description

L'invention a pour objet un dispositif qui sert à interdire tout accès non autorisé aux échelles à crinoline qui existent dans de nombreuses instaLLations industrielLes. Ces échelles conduisent souvent à des appareils dangereux en fonctionnement, ou nécessaires à La sécurité, comme on en trouve dans Les installations électriques à L'air Libre, dans Les raffineries de pétrole, dans Les gares importantes des chemins de fer, etc... IL est donc souhaitable que seules Les personnes autorisées puissent emprunter ces échelles.The subject of the invention is a device which is used to prohibit any unauthorized access to the crinoline ladders which exist in numerous industrial installations. These scales often lead to dangerous devices in operation, or necessary for safety, as found in electrical installations in the open air, in oil refineries, in important railway stations, etc ... It is therefore desirable that only authorized persons can use these ladders.

IL existe des règles qui prescrivent de munir Le premier arceau d'une échelle à crinoline d'une sorte de clapet articulé autour d'un axe horizontal afin qu'on puisse Le mettre et l'immobiliser dans Le plan de cet arceau et condamner ainsi toute introduction à L'intérieur de La crinoline.There are rules which prescribe to equip the first hoop with a crinoline ladder of a kind of valve articulated around a horizontal axis so that one can put it and immobilize it in the plane of this hoop and thus condemn Any introduction to the interior of the crinoline.

Mais, de cette façon, on ne condamne pas La partie de l'échelle qui se trouve en dehors de La crinoline; en outre, quand une personne autorisée emprunte l'échelle après avoir mis Le clapet à sa position d'ouverture dans LaqueLLe ce clapet pend à partir de son articulation, il est extrêmement malaisé à cette personne de remettre derrière eLLe, en empruntant L'écheLLe, ce clapet à sa position de fermeture.But, in this way, we do not condemn the part of the scale which is outside of the crinoline; moreover, when an authorized person borrows the ladder after having put the flap in its open position in which this flap hangs from its articulation, it is extremely difficult for this person to put back behind it, by borrowing the ladder , this valve in its closed position.

L'invention a pour but principal d'éliminer ces inconvénients en apportant un dispositif de condamnation d'une échelle à crinoline en empêchant tout accès à La partie terminale située entre Le dernier barreau de L'écheLLe et Le dernier arceau de La crinoline, en obturant ce dernier arceau.The main purpose of the invention is to eliminate these drawbacks by providing a device for locking a crinoline ladder by preventing any access to the terminal part situated between the last bar of the crane and the last arch of the crinoline, in closing this last arch.

Un autre but de L'invention est de parvenir à un dispositif du type défini ci-dessus qui se ferme et qui se verrouille derrière une personne qui emprunte L'écheLLe à L'intérieur de La crinoLine et qui peut être Libéré facilement, sans cLé, par cette même personne quand elle veut sortir de La crinoline et quitter l'échelle.Another object of the invention is to achieve a device of the type defined above which closes and which locks behind a person who borrows the ladder inside the crinoLine and which can be released easily. ment, without key, by the same person when she wants to get out of the crinoline and leave the ladder.

L'invention a encore pour but d'apporter un dispositif teL que défini ci-dessus qui, en plus, se ferme et se verrouille automatiquement derrière une personne qui emprunte l'échelle à L'intérieur de La crinoline.The invention also aims to provide a teL device as defined above which, in addition, closes and locks automatically behind a person who takes the ladder inside the crinoline.

Un dispositif conforme à L'invention comprend un panneau pivotant autour de gonds fixés à un montant de La partie terminale entre Le dernier barreau de l'échelle et Le dernier arceau de La crinoline; ce panneau est muni à son extrémité supérieure d'un disque d'obturation qui vient, en position de fermeture du panneau empêcher L'accès à L'intérieur de La crinoline. En outre, Le panneau est équipé au moins d'un moyen de verrouiLLage en position de fermeture et de déverrouillage, ce moyen de verrouillage et de déverrouiLLage étant pourvu d'une part d'un organe de déverrouillage accessible de L'intérieur de La crinoline, d'autre part d'une serrure à cLé accessible de L'extérieur du panneau. De préférence, L'organe de déverrouillage n'est manoeuvrable que de L'intérieur de La crinoline par toute personne se trouvant sur L'écheLLe à L'intérieur de La crinoline quand Le panneau est fermé.A device according to the invention comprises a panel pivoting around hinges fixed to an upright of the terminal part between the last bar of the ladder and the last arch of the crinoline; this panel is provided at its upper end with a closing disc which, in the closed position of the panel, prevents access to the interior of the crinoline. In addition, the panel is equipped with at least one locking means in the closed and unlocked position, this locking and unlocking means being provided on the one hand with an unlocking member accessible from the inside of the crinoline. , on the other hand, a key lock accessible from the outside of the panel. Preferably, the unlocking member can only be operated from inside the crinoline by any person on the ladder inside the crinoline when the panel is closed.

SeLon un premier exemple de réalisation de L'invention, Le moyen de verrouillage et de déverrouillage comprend un élément de verrouillage monté pivotant dans sa partie médiane autour d'un axe horizontal porté par Le montant de L'écheLLe opposé au montant qui porte Les gonds du panneau et cet élément est articulé avec une première bieLLette qui s'étend jusqu'à son articulation avec un Levier intermédiaire monté pivotant dans sa partie médiane sur Le même montant de L'écheLLe à un niveau éloigné de celui du disque d'obturation fixé au panneau. Ce Levier intermédiaire est muni d'un doigt d'arrêt qui, dans une première position de ce Levier, s'oppose à L'ouverture du panneau et qui, dans une seconde position de ce Levier, permet L'ouverture du panneau. Ce Levier intermédiaire est articulé à L'opposé de La première biellette, par rapport à L'axe horizontal, avec une seconde biellette qui se prolonge vers Le haut où eLLe est articulée avec un Levier de manoeuvre Lui-même monté pivotant dans sa partie médiane sur Le même montant de l'échelle.According to a first embodiment of the invention, the locking and unlocking means comprises a locking element pivotally mounted in its middle part around a horizontal axis carried by the upright of the ladder opposite the upright which carries the hinges of the panel and this element is articulated with a first bevel which extends to its articulation with an intermediate lever mounted pivoting in its middle part on the same amount of the scale at a level distant from that of the fixed shutter disc to the panel. This intermediate lever is provided with a stop finger which, in a first position of this lever, opposes the opening of the panel and which, in a second position of this lever, allows the opening of the sign. This intermediate lever is articulated opposite the first link, with respect to the horizontal axis, with a second link which extends upwards where it is articulated with an operating lever itself pivotally mounted in its middle part. on the same amount of the scale.

De préférence, Les positions de l'élément de verrouiLLage et du Levier intermédiaire sont contrariées, de sorte que Le doigt d'arrêt est en position de retenue du panneau fermé quand l'élément de verrouillage est à une position qui ne permet pas La mise en place du cadenas de verrouillage.Preferably, the positions of the locking element and of the intermediate lever are opposed, so that the stop finger is in the position for retaining the closed panel when the locking element is in a position which does not allow the setting in place of the lock padlock.

Ainsi, une personne qui emprunte L'écheLLe après avoir mis Le panneau en position d'ouverture peut tirer ce dernier à sa position de fermeture et, à L'aide du Levier de manoeuvre, peut immobiliser Le panneau à sa position de fermeture en interdisant son verrouillage de L'extérieur à L'aide de l'élément de verrouillage.Thus, a person who borrows the ladder after having put the panel in the open position can pull the latter to its closed position and, using the operating lever, can immobilize the panel in its closed position by prohibiting Lock it from the outside using the locking element.

SeLon un exemple préféré de réalisation de L'invention, Le dispositif comprend un moyen de fermeture automatique du panneau constitué par L'un quelconque des moyens suivants : gonds déportés par rapport à La verticale, gonds à ressort, contrepoids de rappel, etc.. et Le moyen de verrouiLLage automatique comprend une serrure à pène demi-tour ou équivalent, du type à fermeture en claquant, cette serrure ayant un axe de manoeuvre de ce pène et un trou de serrure accessible de L'extérieur par une cLé de manoeuvre dudit pène. Le panneau est creux, au moins partieLLement, dans son épaisseur, et il contient Le moyen de déverrouillage qui comprend une tige montée coulissante contre L'action d'un moyen de rappel; à une extrémité cette tige est reliée fonction-nellement par une pièce de manoeuvre à L'axe de manoeuvre du pène; à son extrémité opposée cette même tige est pourvue d'un élément d'appui qui se trouve sur Le panneau et qui est accessible de L'intérieur de La crinoline quand Le panneau est en position de fermeture.According to a preferred embodiment of the invention, the device comprises a means for automatically closing the panel consisting of any one of the following means: hinges offset relative to the vertical, spring hinges, return counterweight, etc. and the automatic locking means comprises a latch bolt lock or equivalent, of the snap-fastening type, this lock having an axis of operation of this bolt and a keyhole accessible from the outside by a key for operating said said bolt. The panel is hollow, at least partially, in its thickness, and it contains the unlocking means which comprises a rod mounted to slide against the action of a return means; at one end, this rod is functionally connected by an operating part to the pin operating axis; at its opposite end, this same rod is provided with a support element which is located on the panel and which is accessible from the interior of the crinoline when the panel is in the closed position.

De préférence, l'élément d'appui est entouré sur trois côtés par une plaque de garde empêchant de Le manoeuvrer à partir de L'extérieur de La crinoline.Preferably, the support element is surrounded on three sides by a guard plate preventing it from being maneuvered from outside the crinoline.

Dans un exemple particulier de réalisation de L'invention, Le disque d'obturation est articulé par rapport au panneau et rabattable dans Le plan de ce dernier quand Le panneau est en position d'ouverture. De préférence, Le disque d'obturation est rabattable dans Le prolongement du plan du panneau. Avantageusement, Le panneau est creux et iL contient un mécanisme de manoeuvre du disque d'obturation. SeLon un mode de réalisation, ce mécanisme comprend une tige articulée avec Le disque et articulée avec un poussoir qui s'applique contre un montant de L'écheLLe.In a particular embodiment of the invention, the shutter disc is articulated relative to the panel and foldable in the plane of the latter when the panel is in the open position.

En se reportant aux figures 1,2, on peut voir une échelle à crinoline destinée à monter dans LaqueLLe Le dernier barreau de l'échelle est près du soL et Le dernier arceau de La crinoline est éloigné. du soL.Referring to Figures 1,2, we can see a crinoline ladder intended to climb in LaqueLLe The last bar of the ladder is near the floor and The last hoop of La crinoline is far away. of the ground.

Cette échelle 1 à deux montants 2,3 est pourvue d'une crinoline 4 dont L'arceau 5 Le plus inférieur est à une distance au-dessus du soL de L'ordre de 2,300 m. Un panneau 6 ayant La Largeur de L'écheLLe 1 est monté pivotant par un de ses bords Longitudinaux grâce à deux gonds 7,8 fixés au montant 3 en deux points espacés en sens verticaL. Le panneau 6 s'étend au moins entre Le dernier barreau de l'échelle et Le dernier arceau de La crinoline. A son extrémité supérieure Le panneau 6 est pourvu d'un disque d'obturation 9 de dimension sensiblement égale à celle de L'arceau inférieur 5 et capable d'interdire L'accès à La crinoline.This ladder 1 with two uprights 2,3 is provided with a crinoline 4, the lower arch 5 of which is at a distance above the floor of the order of 2,300 m. A panel 6 having the width of the ladder 1 is pivotally mounted by one of its longitudinal edges thanks to two hinges 7,8 fixed to the upright 3 at two points spaced vertically. The panel 6 extends at least between the last bar of the ladder and the last arch of the crinoline. At its upper end The panel 6 is provided with a sealing disc 9 of dimension substantially equal to that of the lower arch 5 and capable of prohibiting access to the crinoline.

Sur Le montant 2 opposé au montant 3 qui porte Les gonds 7,8, sensiblement au milieu de La hauteur du panneau 6, un élément de verrouillage 10 est monté pivotant dans sa partie médiane autour d'un axe horizontal 11. Cet élément est percé, en avant du panneau 6 mis en position de fermeture, d'un trou 12 auquel correspond alors, dans cette même position du panneau, un trou percé en correspondance dans une patte de verrouillage 13 fixée au panneau 6. Un cadenas peut alors être engagé dans Les deux trous pour condamner L'ouverture du panneau 6.On the upright 2 opposite the upright 3 which carries the hinges 7,8, substantially in the middle of the height of the panel 6, a locking element 10 is pivotally mounted in its middle part around a horizontal axis 11. This element is drilled , in front of the panel 6 put in the closed position, a hole 12 to which then corresponds, in this same position of the panel, a hole drilled in correspondence in a locking tab 13 fixed to the panel 6. A padlock can then be engaged in the two holes to block the opening of the panel 6.

A son extrémité opposée par rapport à L'axe 11, l'élément de verrouillage 10 est articulé en 10A avec une première bieLLette 14 qui s'étend vers Le haut jusqu'au-dessus du disque d'obturation 9. Cette biellette 14 est disposée en position oblique, de L'arrière de l'échelle 1 jusqu'en avant de celle-ci où son extrémité Libre 14A est articulée en 15 avec une extrémité d'un Levier intermédiaire 16 qui est monté pivotant dans sa partie médiane autour d'un axe horizontal 17 porté par Le même montant 2 de L'écheLLe.At its opposite end with respect to the axis 11, the locking element 10 is articulated at 10A with a first link 14 which extends upwards above the closure disc 9. This link 14 is arranged in an oblique position, from the rear of the ladder 1 to the front of the latter where its free end 14A is articulated at 15 with one end of an intermediate lever diary 16 which is pivotally mounted in its middle part around a horizontal axis 17 carried by the same upright 2 of the ladder.

Quand L'éLément de verrouillage 10 est horizontal, Le Levier intermédiaire 16 est incliné par rapport à L'horizontale avec son articulation 15 située au niveau Le plus élevé. A son extrémité opposée, au-delà de L'axe 17, ce Levier intermédiaire 16 est articulé en 18 avec une seconde biellette 19 qui s'étend vers Le haut parallèlement au montant 2 de L'écheLLe sur une Longueur de 1,50 m environ pour être articulée à son extrémité Libre, en 20, avec un Levier de déverrouillage 21. CeLui-ci est monté pivotant sur Le montant 2 de L'écheLLe au moyen d'un axe horizontal 22; iL s'étend à L'intérieur de La crinoline 4 pour pouvoir être facilement saisi et manoeuvré; il occupe toujours une position dans LaqueLLe il est parallèle au Levier intermédiaire 16.When the locking element 10 is horizontal, the intermediate lever 16 is inclined relative to the horizontal with its articulation 15 located at the highest level. At its opposite end, beyond the axis 17, this intermediate lever 16 is articulated at 18 with a second link 19 which extends upwards parallel to the upright 2 of the ladder over a length of 1.50 m. approximately to be articulated at its free end, at 20, with an unlocking lever 21. This is pivotally mounted on the upright 2 of the ladder by means of a horizontal axis 22; iL extends inside the crinoline 4 so that it can be easily grasped and maneuvered; it always occupies a position in LaqueLLe it is parallel to the Intermediate lever 16.

Ce Levier intermédiaire 16 est muni, en un point situé entre son axe de pivotement 17 et son articulation 15 avec La première biellette 14, d'un doigt d'arrêt 23 dirigé vers Le bas qui peut pénétrer dans une ouverture correspondante (non visible sur Les dessins) prévue dans L'épaisseur du panneau 6, quand ce dernier est à sa position de fermeture et quand ce Levier intermédiaire 16 est mis en position horizontale.This intermediate lever 16 is provided, at a point situated between its pivot axis 17 and its articulation 15 with the first link 14, with a stop finger 23 directed downwards which can penetrate into a corresponding opening (not visible on The drawings) provided in the thickness of the panel 6, when the latter is in its closed position and when this intermediate lever 16 is placed in the horizontal position.

Le fonctionnement du dispositif que L'on vient de décrire est Le suivant.The operation of the device that has just been described is as follows.

En position de protection, Le panneau 6 est fermé, La partie inférieure de l'échelle 1 et L'entrée de La crinoLine 4 sont inaccessibles; l'élément de verrouiLLage 10 est horizontal (position où il est représenté en trait pLein) et un cadenas est fermé dans son trou 12 et dans celui de La patte 13. Le Levier intermédiaire 16 et Le Levier de manoeuvre 21 sont inclinés vers Le haut (position où ils sont représentés en trait pLein) et Le doigt d'arrêt 23 n'est pas engagé dans L'ouverture correspondante prévue dans Le panneau 6.In the protective position, the panel 6 is closed, the lower part of the ladder 1 and the entrance to the crinoLine 4 are inaccessible; the locking element 10 is horizontal (position where it is shown in solid line) and a padlock is closed in its hole 12 and in that of the tab 13. The intermediate lever 16 and the operating lever 21 are tilted upwards (position where they are represented in pLein line) and The stop finger 23 is not engaged in the corresponding opening provided in panel 6.

Quand on a retiré Le cadenas du trou 12, on peut ouvrir Le panneau 6, monter à l'échelle 1 et s'engager dans La crinoline 4.When you have removed the padlock from hole 12, you can open Panel 6, climb to ladder 1 and engage in The crinoline 4.

Dès qu'on a dépassé Le disque 9, on peut refermer Le panneau 6, par exemple avec un pied s'appuyant sur Le dessus du disque 9. A ce moment Le Levier de déverrouillage 21 est accessible et on peut aussitôt Le mettre en position horizontale (où il est représenté en trait mixte), ce qui a pour effet de mettre Le Levier intermédiaire 16 en position horizontale aussi et d'engager Le doigt d'arrêt 23 dans L'ouverture correspondante du panneau 6 mis en position de fermeture. En même temps, l'élément de verrouillage 10 est mis en position oblique à LaqueLLe il est représenté en trait mixte.As soon as we have exceeded the disc 9, we can close the panel 6, for example with a foot resting on the top of the disc 9. At this moment the unlocking lever 21 is accessible and we can immediately put it in position horizontal (where it is shown in phantom), which has the effect of placing the intermediate lever 16 in the horizontal position also and of engaging the stop finger 23 in the corresponding opening of the panel 6 placed in the closed position. At the same time, the locking element 10 is placed in an oblique position to LaqueLLe and is shown in phantom.

Ainsi Le panneau 6 est retenu à nouveau en position de fermeture par Le doigt d'arrêt 23 mais il n'est plus possible de Le condamner de L'extérieur puisque Le trou 12 de l'élément de verrouillage 10 et celui de La patte 13 ne sont plus en correspondance.Thus the panel 6 is retained again in the closed position by the stop finger 23 but it is no longer possible to condemn it from the outside since the hole 12 of the locking element 10 and that of the tab 13 are no longer in correspondence.

Bien entendu, il serait possible de rabattre en position horizontale l'élément de verrouillage 10 à sa position de verrouillage, ce qui remettrait Le Levier de déverrouillage 21 en position également horizontale; mais on peut prévoir, si on Le juge bon, dans Le Levier de déverrouiLLage 21 et dans Le montant 2 de l'échelle, deux trous (non représentés) qui seraient en correspondance quand ce Levier 21 est en position horizontale, de sorte que La personne engagée dans La crinoline 4 pourrait interdire La remise de l'élément de verrouillage tant qu'elle n'est pas descendue de l'échelle.Of course, it would be possible to fold the locking element 10 to its locking position in a horizontal position, which would put the unlocking lever 21 also in a horizontal position; but one can foresee, if one sees fit, in the unlocking lever 21 and in the upright 2 of the ladder, two holes (not shown) which would be in correspondence when this lever 21 is in horizontal position, so that the a person engaged in the crinoline 4 could prohibit the delivery of the locking element until it has come down the ladder.

Dans cet exemple préféré de réalisation, Les positions de l'élément de verrouillage 10 et du Levier de déverrouillage 21 sont contrariées, L'un permettant Le verrouillage ou La retenue du panneau 6 en position de fermeture quand L'autre ne Le permet pas. On pourrait, en variante, donner à cet élément 10 et à ce Levier 21 des positions parallèles telles qu'ils se trouveraient en même temps à Leurs positions de verrouillage et de retenue du panneau 6 fermé en correspondance avec La position horizontale du Levier 16 retenant par son doigt d'arrêt 23 Le panneau 6 en position de fermeture.In this preferred embodiment, the positions of the locking element 10 and the unlocking lever 21 are opposed, one allowing the worm rusting or Retention of the panel 6 in the closed position when the other does not allow it. One could, as a variant, give this element 10 and this lever 21 parallel positions such that they would be at the same time at their locking and retaining positions of the panel 6 closed in correspondence with the horizontal position of the lever 16 retaining by its stop finger 23 The panel 6 in the closed position.

On se reportera maintenant aux figures 3 à 5 où Les pièces identiques ou équivalentes à celles de L'exempLe des figures 1,2 ont été désignées par Les mêmes références que sur ces dernières.Reference will now be made to FIGS. 3 to 5 where the parts identical or equivalent to those of the example of FIGS. 1,2 have been designated by the same references as on the latter.

On retrouve sur La figure 3 L'écheLLe 1 avec ses deux montants 2,3, La crinoline 4 qui s'interrompt au-dessus du panneau pivotant 6 muni du disque d'obturation 9.We find in FIG. 3 the ladder 1 with its two uprights 2,3, the crinoline 4 which is interrupted above the pivoting panel 6 provided with the shutter disc 9.

Le moyen de verrouiLLage 10 comprend un élément de fermeture 24 fixé au montant 2 ayant une gâche destinée à recevoir un pène du type demi-tour, à fermeture en cLaquant, d'une serrure 25 fixée en correspondance sur Le panneau 6. Cette serrure 25 a un axe de manoeuvre 26 qui permet de manoeuvrer le pène, mais cette tige 26 n'est pas accessible de L'extérieur de La serrure 25. Cependant,ainsi qu'il est connu, une clef qui s'introduit dans La serrure 25 permet de manoeuvrer Le pène de L'extérieur du panneau 6.The locking means 10 comprises a closing element 24 fixed to the upright 2 having a keeper intended to receive a bolt of the half-turn type, with snap-fastening, of a lock 25 fixed in correspondence to the panel 6. This lock 25 has an operating pin 26 which makes it possible to maneuver the bolt, but this rod 26 is not accessible from the outside of the lock 25. However, as is known, a key which is introduced into the lock 25 used to maneuver the bolt from outside the panel 6.

Le panneau 6 comprend deux parois parallèles qui ménagent entre elles dans L'épaisseur du panneau un volume où L'axe de manoeuvre 26 s'étend pour y être muni d'une pièce de manoeuvre 27- (figure 5). CeLLe-ci a une partie extrême 27A dans LaqueLLe est ménagée une fente allongée 28 traversée Librement par une broche 29. Cette dernière est supportée dans Les deux branches 30 d'une chape 31 qui contiennent entre elles La partie extrême 27A de La pièce de manoeuvre 27.The panel 6 comprises two parallel walls which form between them in the thickness of the panel a volume where the operating pin 26 extends to be provided with an operating part 27- (Figure 5). This has an end part 27A in which an elongated slot 28 is formed which is freely traversed by a pin 29. The latter is supported in the two branches 30 of a yoke 31 which contain between them the end part 27A of the operating part. 27.

La chape 31 est fixée à une tige coulissante 32 qui est guidée dans L'épaisseur du panneau 6 par des fourreaux de guidage 33, 34 attaché à une des parois de ce panneau. La tige 32 se prolonge vers Le haut à partir du niveau de La serrure 25 jusqu'au-dessus du bord supérieur 6A du panneau. Le sommet de La tige 32 est muni au-dessus du panneau 6 et du disque d'obturation 9 d'une pédale d'appui 35.The yoke 31 is fixed to a sliding rod 32 which is guided in the thickness of the panel 6 by furnaces guide rails 33, 34 attached to one of the walls of this panel. The rod 32 extends upwards from the level of the lock 25 to above the upper edge 6A of the panel. The top of the rod 32 is provided above the panel 6 and the closure disc 9 with a support pedal 35.

Un ressort de compression 36 entoure sur une partie de sa Longueur La tige coulissante 32; il prend appui d'une part contre Le fourreau de guidage 33 et d'autre part contre une goupille 37 qui traverse La tige 32. Cette dernière est ainsi toujours rappelée vers une position supérieure visible sur Les figures 3 à 5 à LaqueLLe La pédale 35 est à son niveau Le plus haut au-dessus du disque d'obturation 9 et Le pène est engagé dans La gâche quand Le panneau 6 est en position de fermeture.A compression spring 36 surrounds on a part of its length the sliding rod 32; it is supported on the one hand against the guide sleeve 33 and on the other hand against a pin 37 which passes through the rod 32. The latter is thus always recalled towards a higher position visible in FIGS. 3 to 5 on the bottom of the pedal 35 is at its highest level above the shutter disc 9 and the bolt is engaged in the keeper when the panel 6 is in the closed position.

Dans cet exemple Le panneau 6 est monté pour revenir automatiquement à sa position de fermeture sous L'effet d'un moyen connu comme un ressort ou un contrepoids de fermeture ou par suite d'une position décalée des gonds.Cette fermeture automatique est possible aussi avec L'exempLe des figures 1 et 2. De cette façon, quand une personne a ouvert Le panneau 6 à L'aide de La cLé de La serrure 25 et s'est engagée dans La crinoline 4 en montant à L'écheLLe, Le panneau 6 se ferme automatiquement. Le pène s'engage dans La gâche de L'éLément de fermeture 24; personne ne peut ouvrir à nouveau Le panneau 6 sans posséder La cLé. Mais, quand cette personne descend de l'échelle, iL Lui suffit d'appuyer avec un pied sur La pédale 35 pour agir par L'intermédiaire de La tige coulissante 32 sur L'axe de manoeuvre 26 du pène et ainsi déverrouiller et ouvrir Le panneau 6.In this example Panel 6 is mounted to automatically return to its closed position under the effect of a means known as a closing spring or counterweight or as a result of an offset position of the hinges. This automatic closing is also possible with the example of Figures 1 and 2. In this way, when a person opened the panel 6 using the key of the lock 25 and engaged in the crinoline 4 while climbing to the ladder, the panel 6 closes automatically. The bolt engages in the keeper of the closing element 24; no one can open panel 6 again without having the key. But, when this person descends the ladder, he just has to press with one foot on the pedal 35 to act via the sliding rod 32 on the operating pin 26 of the bolt and thus unlock and open the panel 6.

De préférence, La pédale 35 est entourée sur trois côtés par une plaque de garde 38 comme indiqué en trait mixte sur La figure 4, afin qu'elle soit inaccessible de L'extérieur.Preferably, the pedal 35 is surrounded on three sides by a guard plate 38 as indicated in phantom in Figure 4, so that it is inaccessible from the outside.

On notera que Le moyen de verrouiLLage et de déverrouillage du mode préféré de réalisation peut être utiLisé, si on Le désire, sans Le moyen de fermeture automatique du panneau.Note that the means of locking and unlocking the preferred embodiment can be used, if desired, without the means of automatically closing the panel.

Les figures 6 à 9 se rapportent à un exemple de réalisation du dispositif de L'invention avec une échelle descendante à partir d'une plate-forme 39. Dans La descriptic qui suit on utilisera Les mêmes références que sur Les figures précédentes pour désigner Les pièces identiques ou équivaLentes.Figures 6 to 9 relate to an exemplary embodiment of the device of the invention with a descending scale from a platform 39. In the description which follows, the same references will be used as in the preceding figures to designate the identical or equivalent parts.

L'écheLLe 1 a deux montants 2,3 qui sont prolongés, sans barreaux, au-dessus du niveau de La pLateforme 39; Les prolongements peuvent faire partie intégrante des montants 2,3 eux-mêmes, ou être rapportés en bout de ces derniers,ou encore faire partie d'un garde-corps 40 (représenté partiellement seulement) qui borde La plateforme 39. QueL que soit Le cas, par simplification, on admettra ici que ce sont Les montants 2,3 qui s'étendent sensiblement jusqu'au sommet du garde-corps 40. Les barreaux de L'écheLLe s'arrêtent à peu près au niveau de La plateforme 39 tandis que Le dernier arceau de La crinoline 4 se trouve à peu près au niveau du sommet du garde-corps 40. Le panneau 6 muni du disque d'obturation 9 est monté à L'aide de gonds à ressort sur Le montant 3 afin d'interdire L'accès à L'écheLLe 1 en fermant l'intervalle entre Les montants 2,3 au-dessus de La plateforme 39 sensiblement entre Le dernier barreau de l'échelle et Le dernier arceau de La crinoline 4.SCALE 1 has two uprights 2,3 which are extended, without bars, above the level of platform 39; The extensions can be an integral part of the uprights 2,3 themselves, or be attached to the end of the latter, or even be part of a railing 40 (shown only partially) which borders the platform 39. Whatever the case, for simplification, it will be assumed here that these are the uprights 2,3 which extend substantially to the top of the railing 40. The bars of the ladder stop roughly at the level of the platform 39 while that the last hoop of the crinoline 4 is located approximately at the level of the top of the railing 40. The panel 6 provided with the shutter disc 9 is mounted using spring hinges on the upright 3 in order to prohibit access to ladder 1 by closing the gap between the uprights 2,3 above the platform 39 substantially between the last bar of the ladder and the last hoop of the crinoline 4.

Le panneau 6 a une serrure (non représentée) à LaqueLLe correspond un élément de fermeture à gâche, comme dans L'exempLe des figures 3 à 5, de sorte que ce panneau se ferme et se verrouille automatiquement à partir de sa position d'ouverture.The panel 6 has a lock (not shown) to which there corresponds a strike closure element, as in the example of FIGS. 3 to 5, so that this panel closes and locks automatically from its open position .

Le moyen de déverrouillage est visible en détail sur Les figures 7,8. IL comprend à partir de L'axe de manoeuvre 26 de La serrure Les mêmes pièces 27 à 34 que celles décrites plus haut, sauf que La tige coulissante 32 est plus courte et ne s'étend pas au dehors du panneau 6. A son extrémité inférieure, opposée à celle à LaqueLLe eLLe est reliée fonctionneLLement à La serrure, La tige coulissante 32 est articulée par L'intermédiaire d'une biellette 41 (mieux visible sur La figure 7) avec une barre bascuLante 42 qui se trouve en dehors du panneau 6.The unlocking means is visible in detail in Figures 7,8. It comprises from the operating axis 26 of the lock The same parts 27 to 34 as those described above, except that the sliding rod 32 is shorter and does not extend outside the panel 6. At its lower end, opposite to that at which it is functionally connected to the lock, the sliding rod 32 is articulated by means of a link 41 (better visible in FIG. 7) with a tilting bar 42 which is located outside the panel 6.

La barre basculante 42 est située dans Le bas du panneau 6 pour être accessible de L'intérieur de La crinoLine quand on atteint Le haut de L'écheLLe 1. Cette barre 42 a deux branches extrêmes transversales 43 qui pénètrent partiellement à L'intérieur du panneau 6 pour être articuLées autour d'un axe 44 supporté par un palier 45.The tilting bar 42 is located at the bottom of the panel 6 to be accessible from the inside of the crinoLine when one reaches the top of the ladder 1. This bar 42 has two end transverse branches 43 which partially penetrate inside the panel 6 to be articulated around an axis 44 supported by a bearing 45.

Dans cet exemple, La barre basculante 42 qui est articulée par rapport au panneau 6 constitue l'élément d'appui constitué dans l'exemple des figures 3 à 5 par La pédale 35. Cette barre 42 pourrait aussi être entourée sur trois côtés par une plaque de garde interdisant tout accès de L'extérieur de La crinoline.In this example, the tilting bar 42 which is articulated relative to the panel 6 constitutes the support element formed in the example of FIGS. 3 to 5 by the pedal 35. This bar 42 could also be surrounded on three sides by a guard plate preventing any access from outside the crinoline.

Quand il s'agit d'une échelle descendante, iL est spécialement avantageux de monter Le disque d'obturation 9 sur Le bord supérieur 6A du panneau 6 au moyen de gonds 46 permettant de rabattre ce disque 9 dans Le plan du panneau 6 quand celui-ci est mis en position d'ouverture; ce montage est spécialement utile quand Le panneau 6 ne peut pivoter que de 90° environ à partir de sa position de fermeture.When it is a descending scale, it is especially advantageous to mount the shutter disc 9 on the upper edge 6A of the panel 6 by means of hinges 46 making it possible to fold this disc 9 into the plane of the panel 6 when that -this is put in the open position; this mounting is especially useful when the panel 6 can only pivot about 90 ° from its closed position.

Les mouvements du panneau 6 peuvent Lui être imposés manuellement et des moyens d'immobilisation à ses deux positions extrêmes peuvent être prévus.The movements of the panel 6 can be imposed manually on it and immobilization means at its two extreme positions can be provided.

Mais iL est préférable d'employer un mécanisme de manoeuvre Logé dans L'épaisseur du panneau 6 et capable de mouvoir automatiquement Le disque d'obturation 9 entre une première position où ce disque est perpendiculaire au panneau 6 (comme sur La figure 6) et une seconde position où iL est relevé dans Le prolongement du panneau 6, à peu près dans Le même plan que ce dernier.But it is preferable to use an operating mechanism housed in the thickness of the panel 6 and capable of automatically moving the shutter disc 9 between a first position where this disc is perpendicular to the panel 6 (as in FIG. 6) and a second position where iL is raised in the extension of panel 6, roughly in the same plane as the latter.

Le disque d'obturation 9 est muni sur son côté fixé aux gonds 46 d'une chape 47, située de préférence à une position centrale entre Les gonds 46. Cette chape 47 sert à L'articuLation autour d'un axe 48 d'une tige 49 qui s'étend vers Le bas dans L'épaisseur du panneau 6 où eLLe est guidée en coulissement par un guide 50; cette tige 49 se termine, sensiblement dans Le milieu du panneau 6, par un étrier 51 qui contient entre ses branches un poussoir 52. Ce dernier a un profil en demi-cercle; iL est articulé en deux points qui sont sensibLement opposés diamétralement d'une part avec L'étrier 51 par un axe 53, d'autre part avec Le panneau 6 au moyen d'un axe 54. Ce dernier est monté Libre en coulissement dans une fente 55, non paraLLèLe à La tige 49, de préférence perpendiculaire à cette dernière. Cette fente 55 est ménagée dans une pièce de guidage en U 56 qui fait partie du panneau 6.The shutter disc 9 is provided on its side fixed to the hinges 46 with a yoke 47, preferably located at a central position between the hinges 46. This yoke 47 is used for articulation around an axis 48 of a rod 49 which extends downwards in the thickness of panel 6 where it is guided in sliding by a guide 50; this rod 49 ends, substantially in the middle of the panel 6, by a stirrup 51 which contains between its branches a pusher 52. The latter has a semi-circular profile; It is articulated at two points which are diametrically opposite on the one hand with the stirrup 51 by an axis 53, on the other hand with the panel 6 by means of an axis 54. The latter is mounted to slide freely in a slot 55, not parallel to rod 49, preferably perpendicular to the latter. This slot 55 is formed in a U-shaped guide part 56 which forms part of the panel 6.

Le poussoir 52 est susceptible d'être partiellement en saillie en dehors du panneau 6, par une tranche LongitudinaLe de ce dernier qui possède une ouverture correspondante, du côté où se trouvent Les gonds 7 de montage de ce panneau 6 sur Le montant 3, comme indiqué en trait mixte sur La figure 10. A cette position du poussoir 52, L'axe 54 est à L'extrémité extérieure de La fente 55; L'étrier 51 et L'axe 53 sont alors à Leur position inférieure, indiquée en trait mixte, et Le disque d'obturation 9 est dressé, comme indiqué aussi en trait mixte sur La figure 9. Cette situation peut s'obtenir grâce à un ressort de compression 57 qui entoure La tige 49 et qui s'appuie d'une part contre Le guide fixe 50, d'autre part contre une rondelle 58 retenue en position sur La tige 49 par un écrou vissé 59. Ce ressort 57 fournit au moins une partie de La force nécessaire au soulèvement du disque d'obturation 9 et Le tient en position dressée.The pusher 52 is likely to be partially projecting outside the panel 6, by a LongitudinaLe slice thereof which has a corresponding opening, on the side where the hinges 7 for mounting this panel 6 on the upright 3, as indicated in phantom in Figure 10. At this position of the pusher 52, the axis 54 is at the outer end of the slot 55; The stirrup 51 and the axis 53 are then in their lower position, indicated in phantom, and the shutter disc 9 is erected, as indicated also in phantom in FIG. 9. This situation can be obtained thanks to a compression spring 57 which surrounds the rod 49 and which rests on the one hand against the fixed guide 50, on the other hand against a washer 58 retained in position on the rod 49 by a screwed nut 59. This spring 57 provides at least part of the force required to lift the shutter disc 9 and hold it in the upright position.

Quand Le poussoir 52 est contraint de rentrer à L'intérieur du panneau 6, par exemple parce qu'il bute contre Le montant 3 pendant Le pivotement du panneau 6, alors L'axe 54 se déplace jusqu'à L'extrémité intérieure de La fente 55; en plus L'axe 53 et L'étrier 51 sont déplacés vers Le haut, comme indiqué en trait plein sur La figure 10, jusqu'à une position qui correspond à La position de fermeture du disque d'obturation 9. Dans cet état, Le poussoir étant en butée contre Le montant 3 quand Le panneau 6 est en position de fermeture, il n'est pas possible de soulever Le disque 9 sans commencer par déverrouiLLer et pousser vers sa position d'ouverture Le panneau 6. Ce n'est que Lorsque, par suite du pivotement du panneau 6, Le poussoir 52 commence à s'écarter du montant 3 qu'il peut commencer à prendre une position saillante comme expliqué plus haut.When the pusher 52 is forced to return to the interior of the panel 6, for example because it abuts with tre The upright 3 during the pivoting of the panel 6, then the axis 54 moves to the inner end of the slot 55; in addition The axis 53 and the stirrup 51 are moved upwards, as indicated in solid lines in FIG. 10, to a position which corresponds to the closed position of the shutter disc 9. In this state, The pusher being in abutment against the upright 3 when the panel 6 is in the closed position, it is not possible to lift the disc 9 without first unlocking and pushing towards its open position The panel 6. when, as a result of the pivoting of the panel 6, the pusher 52 begins to move away from the upright 3 that it can begin to assume a projecting position as explained above.

Ce mécanisme de manoeuvre du disque d'obturation se monte dans L'épaisseur du panneau 6 en plus du moyen de déverrouillage décrit plus haut.This mechanism for operating the closing disc is mounted in the thickness of the panel 6 in addition to the unlocking means described above.
