Cependant, dans certains ascenseurs à traction, les câbles sont dirigés autour de poulies pour assurer une démultiplication, par exemple de The cable makes a multi-strand cable short in a groove of a pulley which is rotated by a motor to propel the cab.

Selon l'invention, les câbles s'étendent jusqu'à un point situé au-dessus du centre de gravité du contrepoids et une part notable de la masse du contrepoids est située au-dessus de la poulie d'entraînement. Cette. "partie supérieure" de contrepoids est située au-dessus du niveau According to the invention, the cables extend to a point above the center of gravity of the counterweight and a substantial part of the weight of the counterweight is located above the drive pulley. This. "upper part" counterweight is located above the level

Le contrepoids est situé du même c6té de la gaine que le moteur d'entraînement de l'ascenseur; le moteur est aussi au-dessus du niveau du palier supérieur, mais sur le côté de la gaine, étant situé auprès de la gaine à une distance D en dessous du sommet de la gaine, D représentant environ The counterweight is located on the same side of the sheath as the drive motor of the elevator; the engine is also above the level of the upper bearing, but on the side of the sheath, being located near the sheath at a distance D below the top of the sheath, D representing approximately
% de la hauteur de la cabine.% of the height of the cabin.
L'invention est illustrée ci-dessous à l'aide d'un exemple et en référence aux dessins sur lesquels: La figure 1 est une vue en élévation simplifiée de l'ascenseur selon l'invention; La figure 2 est une vue en élévation latérale du palier supérieur, vu dans la direction 2 de la figure 1; La figure 3 est une vue en plan suivant la ligne 3-3 The invention is illustrated below with the aid of an example and with reference to the drawings in which: FIG. 1 is a simplified elevational view of the elevator according to the invention; Figure 2 is a side elevational view of the upper bearing, seen in the direction 2 of Figure 1; FIG. 3 is a plan view along the line 3-3
de la figure 1, vu vers le bas de la gaine. of Figure 1, seen towards the bottom of the sheath.
Sur la figure 1, une cabine d'ascenseur 10 se meut dans une gaine 12 définie par les parois 14. La cabine 10 est située au palier supérieur 16. La cabine est reliée à un moteur d'entraînement 18 (voir figure 3) qui fait In Figure 1, an elevator car 10 moves in a sheath 12 defined by the walls 14. The cab 10 is located at the upper bearing 16. The cab is connected to a drive motor 18 (see Figure 3) which made

lèle à un côté de la cabine. Un câble d'ascenseur 22 est accroché à la paroi de la gaine au point 24, d'o il s'étend vers le bas et en dessous du fond de la cabine 10; puis, par deux poulies opposées 26, il remonte à la poulie 20 et alors, décrit un arc 28 autour de la poulie, puis descend jusqu'au contrepoids 30 qui est situé en bas de la gaine. A l'endroit du contrepoids, le câble 22 passe autour d'une poulie de contrepoids 32, retournant de celle-ci à un point d'accrochage 34 sur la paroi de la leash to one side of the cabin. An elevator cable 22 is hooked to the wall of the duct at point 24, where it extends downwards and below the bottom of the cabin 10; then, by two opposite pulleys 26, it goes back to the pulley 20 and then, describes an arc 28 around the pulley, then down to the counterweight 30 which is located at the bottom of the sheath. At the point of the counterweight, the cable 22 passes around a counterweight pulley 32, returning from it to a point of attachment 34 on the wall of the
gaine. La cabine et le contrepoids ont une démultiplica- sheath. The cab and the counterweight have a multiplier
tion de 2: 1.2: 1.
En bas de la gaine 12 se trouvent deux amortisseurs de cabine 36 et un amortisseur de contrepoids 38. Ces At the bottom of the sheath 12 are two cabin dampers 36 and a counterbalance damper 38. These

Par la figure 3, on peut voir que le câble 22 s'étend diagonalement le long du fond de la cabine 10 et que les deux poulies 26 sont situées sur des côtés opposés du centre de gravité de la cabine, par exemple le long de In FIG. 3, it can be seen that the cable 22 extends diagonally along the bottom of the cabin 10 and that the two pulleys 26 are located on opposite sides of the center of gravity of the cabin, for example along the

Sur la figure 2, le contrepoids 30 est représenté dans la position o il se trouve quand la cabine 10 est en bas de la gaine: au sommet de la gaine. Il faut noter d'après la figure 2 qu'une partie notable 43 du contre- poids se trouve au-dessus du niveau du palier 16. Cela se produit parce que le moteur 18 est situé dans l'espace de machine 42 qui est audessus du niveau du palier et In Figure 2, the counterweight 30 is shown in the position where it is when the cab 10 is at the bottom of the sheath: at the top of the sheath. It should be noted from Fig. 2 that a substantial portion 43 of the counterweight is above the level of the bearing 16. This occurs because the motor 18 is located in the machine space 42 which is above level of landing and
parce que le câble 22 s'étend sous la cabine. because the cable 22 extends under the cabin.
Comme le montre la figure 1, la poulie de contre- As shown in Figure 1, the counter pulley
poids 32 est située au milieu du contrepoids et pour la stabilité, son axe de rotation 44 doit être au-dessus du centre de gravité. Toutefois, une part notable de la weight 32 is located in the middle of the counterweight and for stability, its axis of rotation 44 must be above the center of gravity. However, a notable part of the
masse du contrepoids est située au-dessus du point 44. counterweight mass is located above point 44.
Autrement dit, si l'on admet que le contrepoids a une certaine longueur L, environ un quart et jusqu'à un tiers L' de cette longueur peut se trouver au-dessus du centre de rotation 44. Cette relation masse/longueur dépend de la distribution de la masse du contrepoids. Sur la figure 1, le contrepoids est formé de blocs amovibles 46 de fer ou même de béton et les blocs 48 situés au-dessus de la poulie 32 ne sont pas aussi larges que les autres blocs 46, ce qui permet au câble 22 d'entrer dans la poulie In other words, if it is accepted that the counterweight has a length L, about a quarter and up to a third L 'of this length can be above the center of rotation 44. This mass / length relationship depends on the distribution of the mass of the counterweight. In Figure 1, the counterweight is formed of removable blocks 46 of iron or even concrete and the blocks 48 located above the pulley 32 are not as wide as the other blocks 46, which allows the cable 22 of enter the pulley
de contrepoids 32 et d'en sortir.counterweight 32 and out.
L'avantage de cette disposition est qu'une partie de la masse du contrepoids, qui serait normalement située en-dessous de la poulie 32, peut être située au-dessus de la poulie parce qu'il y a, au-dessus du palier 16, de l'espace qu'il peut occuper quand la cabine est en bas de la gaine. La figure 3 aide à comprendre cela; elle montre que le contrepoids 30 est situé auprès du moteur 18. Ainsi, quand la cabine est dans sa position la plus basse dans la gaine, la partie supérieure, par exemple la partie 43 du contrepoids est placée le plus près de The advantage of this arrangement is that a part of the mass of the counterweight, which would normally be below the pulley 32, may be located above the pulley because there is, above the bearing 16, space it can occupy when the cabin is down the shaft. Figure 3 helps to understand this; it shows that the counterweight 30 is located near the engine 18. Thus, when the cab is in its lowest position in the sheath, the upper part, for example the portion 43 of the counterweight is placed closest to
la gaine 20 sur le moteur et au-dessus du niveau du pa- the sheath 20 on the engine and above the level of the
lier. Grâce à cela, la profondeur de la zone de cuvette peut être moindre et la largeur 52 de la gaine peut aussi être considérablement moindre, parce que la largeur 54 du contrepoids peut être réduite et parce qu'on peut inclure dans l'ascenseur la même masse de contrepoids, link. Thanks to this, the depth of the bowl area can be less and the width 52 of the sheath can also be considerably less, because the width 54 of the counterweight can be reduced and because one can include in the elevator the same counterweight mass,

Compte tenu de l'exposé ci-dessus, un praticien peut apporter diverses modifications à l'invention telle qu'elle est ici décrite, sans s'écarter de sa portée et In view of the above, a practitioner may make various modifications to the invention as described herein, without departing from its scope and
