Abstract

The variable-speed conveyor element (transportation device) applied to a handrail, consists of separate handgrips connected together by elements of variable length themselves acting as elements of the handrail, each of these elements consisting of a continuous flexible link such as a belt or cable, to which link are fixed contiguous blocks which prevent or limit the flexing of the element in one sense, the blocks being equipped with bosses and recesses which allow them to nest in one another in order to transmit loads. <IMAGE>

Description

Il est nécessaire, dans certains cas de transporteurs mécaniques, et spécialement dans les trottoirs accélérés, de pouvoir disposer d'éléments, en particulier pour les mains courantes, susceptibles de ne pouvoir fléchir, au moins dans certaines zones, que dans un seul sens. Ce résultat peut être obtenu par l'utilisation de chaînes sur lesquelles sont fixés des blocs qui s'opposent à la flexion. L'état actuel de la question est représenté par les brevets 2 274 523 (PATIN et R.A.T.P.) et 2 431 075 (R.A.T.P.).It is necessary, in certain cases of mechanical conveyors, and especially in accelerated sidewalks, to be able to have elements, in particular for the handrails, susceptible of being able to bend, at least in certain areas, only in one direction. This result can be obtained by the use of chains on which are fixed blocks which oppose bending. The current state of the matter is represented by patents 2,274,523 (PATIN and R.A.T.P.) and 2,431,075 (R.A.T.P.).

La main courante objet de ces brevets, est destinée à un trottoir roulant accéléré et est constituée de poignées reliées entre elles deux par deux par un lien souple. Chaque poignée doit être synchrone du point correspondant du plancher mobile, par conséquent les poignées doivent s'écarter dans les zones d'accélération, se rapprocher dans les zones de décélération et rester équidistantes dans les zones à vitesse constante. Ce résultat est obtenu en montant chaque poignée sur un petit chariot, deux chariots successifs étant reliés par un élément de liaison souple flexible dans un seul sens pour assurer un appui éventuel entre deux poignées; l'élément de liaison souple se replie sensiblement à angle droit au droit de la poignée par une poulie et est ancré à un chariot tendeur ou trolley dont la voie peut se rapprocher ou s'écarter de celle du chariot porteur de la poignée, ce qui permet d'assurer la variation de vitesse.The handrail which is the subject of these patents, is intended for an accelerated moving sidewalk and is made up of handles connected together in pairs by a flexible link. Each handle must be synchronous with the corresponding point of the movable floor, therefore the handles must deviate in the acceleration zones, approach in the deceleration zones and remain equidistant in the zones at constant speed. This is achieved by mounting each handle on a small cart, two successive carts being connected by a flexible flexible connecting element in one direction to ensure support possible between two handles; the flexible connecting element folds substantially at right angles to the right of the handle by a pulley and is anchored to a tensioning trolley or trolley, the path of which can approach or deviate from that of the trolley carrying the handle, which ensures speed variation.

Selon ces brevets, l'élément de liaison souple est constitué par une chaîne garnie de blocs dont la forme complexe est déterminée pour que l'élément de liaison travaillant en poutre fléchie sur appuis simples c'est-à-dire soumis à un moment fléchissant et à un effort tranchant, ne se déforme pas sous une charge; en effet, entre deux poignées de main courante, l'élément de liaison souple sert lui-même de main courante, en cas de bousculade par exemple. L'inconvénient principal de ce système est sa complexité, qui entraîne un coût relativement élevé.According to these patents, the flexible connecting element is constituted by a chain filled with blocks whose complex shape is determined so that the connecting element working in a bent beam on simple supports, that is to say subjected to a bending moment and with a sharp force, does not deform under a load; in fact, between two handrail handles, the flexible connecting element itself serves as a handrail, in the event of a stampede, for example. The main drawback of this system is its complexity, which results in a relatively high cost.

Dans le dispositif selon l'invention, l'élément de liaison souple est constitué par un lien souple continu à section constante, tel que courroie, câble ou ensemble de courroies ou de câbles dont la caractéristique est d'offrir une résistance à l'effort tranchant que ne présentent pas les chaînes, associé à des blocs de compression de forme simple s'encastrant les uns dans les autres. A titre d'exemple, il va être décrit l'application d'un tel dispositif à une main courante, mais des dispositifs analogues pourraient être utilisés dans d'autres éléments de transporteurs, tant pour les personnes que pour les marchandises.In the device according to the invention, the flexible connecting element is constituted by a continuous flexible link with a constant section, such as a belt, cable or set of belts or cables whose characteristic is to offer resistance to effort. cutting edge that the chains do not have, associated with compression blocks of simple shape fitting into each other. By way of example, the application of such a device to a handrail will be described, but similar devices could be used in other elements of conveyors, both for people and for goods.

Un élément de main courante, reliant deux poignées, est constitué par un lien souple tendu entre deux points d'attache et passant sur deux poulies de renvoi écartées l'une de l'autre, qui forment avec les deux points d'attache un quadrilatère déformable en fonction de la vitesse de transport, ledit lien équipé d'une série de blocs adjacents comportant chacun une face inférieure de fixation sur le lien, une face supérieure d'appui de la main et deux faces frontales, respectivement avant et arrière, perpendiculaires à la direction du lien, les faces frontales d'un bloc étant en contact sur toute leur hauteur avec les faces frontales correspondantes des blocs adjacents dans une partie rectiligne du lien tendue entre les deux poulies et pouvant s'écarter angulairement dans deux parties convexes du lien tournant sur les poulies, les deux faces frontales, respectivement avant et arrière de chaque bloc, présentant des profils anguleux se déduisant l'un de l'autre par translation parallèle à la direction du lien, chaque face avant d'un bloc comportant au moins un bossage et chaque face arrière comportant au moins un évidement de profil conjugué à celui du bossage, de telle sorte que, dans la partie rectiligne du lien entre les deux poulies, chaque bossage d'une face avant d'un bloc s'emboîte dans un évidement conjugué de la face arrière en regard du bloc adjacent en formant une liaison à tenon et mortaise susceptible de résister aux efforts tranchants appliqués sur le lien, lesdits bossages s'écartant des évidements dans les parties convexes du lien.A handrail element, connecting two handles, consists of a flexible link stretched between two attachment points and passing over two return pulleys spaced from each other, which form with the two attachment points a quadrilateral deformable as a function of transport speed, said link equipped of a series of adjacent blocks each comprising a lower face for fixing to the link, an upper face for supporting the hand and two front faces, respectively front and rear, perpendicular to the direction of the link, the front faces of a block being in contact over their entire height with the corresponding front faces of the adjacent blocks in a rectilinear part of the tensioned link between the two pulleys and being able to deviate angularly in two convex parts of the rotating link on the pulleys, the two front faces, respectively front and rear of each block, having angular profiles deduced from each other by translation parallel to the direction of the link, each front face of a block comprising at least one boss and each rear face comprising at least one recess profile combined with that of the boss, so that, in the rectilinear part of the link between the two pulleys, each boss on a front face of a block s 'fits into a conjugate recess on the rear face opposite the adjacent block, forming a tenon and mortise connection capable of withstanding the cutting forces applied to the link, said bosses deviating from the recesses in the convex parts of the link.

De préférence, le lien souple est constitué par une courroie crantée.Preferably, the flexible link is constituted by a toothed belt.

La constitution et le fonctionnement d'une telle main courante sont décrits par les figures 1 à 4.The constitution and operation of such a handrail are described in Figures 1 to 4.

La figure 1 représente en coupe longitudinale une telle courroie susceptible d'être pliée seulement vers le bas avec un rayon faible dans une certaine zone, mais également vers le haut, avec un rayon beaucoup plus grand, dans une autre zone.Figure 1 shows in longitudinal section such a belt capable of being folded only downwards with a small radius in a certain area, but also upwards, with a much larger radius, in another area.

La figure 2 représente un autre mode de réalisation.Figure 2 shows another embodiment.

Les figures 3 et 4 montrent l'utilisation d'une telle main courante dans un trottoir roulant accéléré.Figures 3 and 4 show the use of such a handrail in an accelerated moving sidewalk.

La figure 1 représente un élément de main courante dont

  • la zone 4 peut se courber avec un rayon de l'ordre de quelques centimètres vers le bas en s'enroulant sur le pignon 7,
  • la zone 5 est rigide et solidaire d'un petit chariot porté par un essieu 9;
  • la zone 6 peut fléchir vers le haut avec un rayon de l'ordre du mètre.
Figure 1 shows a handrail element of which
  • zone 4 can bend downwards with a radius of the order of a few centimeters by winding on pinion 7,
  • zone 5 is rigid and integral with a small carriage carried by an axle 9;
  • zone 6 can flex upwards with a radius of the order of one meter.

La main courante est constituée d'une courroie crantée 10 à laquelle sont fixés des blocs 11 dont la forme permet un emboîtement réciproque entre deux blocs contigus, grâce à un bossage 12 qui vient s'encastrer dans un évidement 13. La fixation d'un bloc au dos de la courroie s'effectue, soit par un collage 14, comme pour les blocs 11a, 11b, soit par un boulonnage 16 sur un insert 15, comme pour les blocs 11c, 11d, cette fixation s'effectuant toujours au droit d'une dent, emplacement de rigidité maximale de la courroie dont la flexion s'effectue essentiellement dans les creux entre dents. L'épaisseur d'un bloc en un point quelconque, mesurée parallèlement au dos de la courroie, est constante et égale au pas des dents.The handrail consists of a toothed belt 10 to which are fixed blocks 11 whose shape allows a reciprocal interlocking between two adjacent blocks, thanks to a boss 12 which comes to be embedded in a recess 13. The fixing of a block on the back of the belt is carried out either by bonding 14, as for blocks 11a, 11b, or by bolting 16 on an insert 15, as for blocks 11c, 11d, this fixing always being carried out at right of a tooth, location of maximum rigidity of the belt whose bending takes place mainly in the hollows between teeth. The thickness of a block at any point, measured parallel to the back of the belt, is constant and equal to the pitch of the teeth.

Le fonctionnement d'un tel système est le suivant: toute charge de la main courante, qui travaille comme une poutre entre appuis simples, introduit un moment de flexion et un effort tranchant. La compression longitudinale due au moment est prise par les têtes des blocs, la tension par la courroie; l'effort tranchant est transmis d'un bloc à l'autre par le couple bossage-évidement et le cisaillement qui en résulte au contact bloc-courroie est repris par le collage 14 ou le boulonnage 16.The operation of such a system is as follows: any load on the handrail, which works like a beam between simple supports, introduces a bending moment and a shearing force. The longitudinal compression due to the moment is taken by the heads of the blocks, the tension by the belt; the shear force is transmitted from one block to another by the boss-recess pair and the resulting shear on contact belt block is taken up by gluing 14 or bolting 16.

Dans la zone 5 rigide, la face intérieure de la courroie est fixée, toujours par collage ou boulonnage, au chariot 8.In the rigid zone 5, the internal face of the belt is fixed, still by gluing or bolting, to the carriage 8.

Dans la zone 6, pour permettre la flexion de la main courante vers le haut, les blocs 11 ont une épaisseur très légèrement décroissante régulièrement du bas vers le haut, la fixation des blocs étant identique à celle de ceux des autres zones.In zone 6, to allow the handrail to bend upwards, the blocks 11 have a thickness which is very slightly decreasing regularly from the bottom up, the fixing of the blocks being identical to that of the other zones.

Sur la figure 2, on a représenté une disposition différente dans laquelle le système a été doté d'une certaine symétrie de fonctionnement, ce qui peut présenter certains avantages. Chaque bloc 17 comporte sur chaque face perpendiculaire à l'axe de la courroie crantée 10 d'une part un bossage 18 et un évidement 19, d'autre part et en regard des précédents, un évidement 20 et un bossage 21. Le fonctionnement de ce dispositif est analogue au précédent. Des formes différentes pourraient être retenues sans sortir du domaine de l'invention.In Figure 2, there is shown a different arrangement in which the system has been provided with a certain operating symmetry, which can have certain advantages. Each block 17 has on each face perpendicular to the axis of the toothed belt 10 on the one hand a boss 18 and a recess 19, on the other hand and opposite the previous ones, a recess 20 and a boss 21. The operation of this device is similar to the previous one. Different forms could be retained without departing from the scope of the invention.

Les figures 3 et 4 montrent l'utilisation d'une telle main courante dans un trottoir roulant accéléré. Un élément de main courante 23 relie entre elles deux poignées de main courante 24a, 24b, en passant par les pignons de renvoi 7a, 7b, et sont ancrés à des trolleys de variation de vitesse 25a, 25b. Les poignées 24a, 24b sont munies de galets portés par les axes 26a, 26b des pignons 7a, 7b. Les essieux 9a, 9b des chariots 8a, 8b sont munis de galets analogues et tous ces galets se déplacent entre deux rails 27 et 28.Figures 3 and 4 show the use of such a handrail in an accelerated moving sidewalk. A handrail element 23 connects two handrail handles 24a, 24b, passing through the return gears 7a, 7b, and are anchored to speed variation trolleys 25a, 25b. The handles 24a, 24b are provided with rollers carried by the axes 26a, 26b of the pinions 7a, 7b. The axles 9a, 9b of the carriages 8a, 8b are provided with similar rollers and all these rollers move between two rails 27 and 28.

Les trolleys de variation de vitesse 25a, 25b auxquels sont ancrées les extrémités des courroies, sont maintenus par un rail 30 à une distance D variable des rails 27 et 28, ce qui permet de faire varier l'écartement des poignées et, par conséquent, leur vitesse, le débit, en nombre de poignées par seconde étant constant.The speed variation trolleys 25a, 25b to which the ends of the belts are anchored, are held by a rail 30 at a variable distance D from the rails 27 and 28, which makes it possible to vary the spacing of the handles and, consequently, their speed, the flow rate, in number of handles per second being constant.

Sur la figure 3, on voit l'ensemble d'un élément dans une zone du trottoir roulant accéléré avec main courante horizontale dans une zone d'augmentation de vitesse.In FIG. 3, we see the whole of an element in an area of the accelerated moving walkway with horizontal handrail in an area of speed increase.

Sur la figure 4, ce même ensemble est dans une zone où la main courante passe d'une section horizontale à une section en rampe. La courbure est prise dans la zone 6, dont le rayon r est évidemment beaucoup plus court que le rayon de raccordement R, les zones à faible vitesse 4 et 5 restant rectilignes.In FIG. 4, this same assembly is in an area where the handrail passes from a horizontal section to a ramped section. The curvature is taken in zone 6, the radius r of which is obviously much shorter than the connecting radius R, the low-speed zones 4 and 5 remaining rectilinear.
