  • the drive device conventionally comprises a motor means 20 which can be constituted for example by a reversible electric motor rotating at linear movement which is a function of time, the output shaft of which is connected to a flexible connecting member 22, shown in dotted lines, by means of a reduction means 24, adapted to reduce the speed of rotation of the output shaft of the motor 20, for example of the pulley and belt type.
  • a motor means 20 which can be constituted for example by a reversible electric motor rotating at linear movement which is a function of time, the output shaft of which is connected to a flexible connecting member 22, shown in dotted lines, by means of a reduction means 24, adapted to reduce the speed of rotation of the output shaft of the motor 20, for example of the pulley and belt type.
  • the flexible connecting member 22 is constituted by a belt, the external surface of which can be provided with teeth, but can be produced, according to another embodiment, by a chain with articulated links, or the like.
  • the connecting member 22 is connected to the leaf 12 and extends between drive rollers 26, 28 and 30 in a plane parallel to the leaf which corresponds to the plane of FIG. 1.
  • the connecting member 22 is connected to actuation means of a mechanism 32 for operating the lock of the landing door not shown.
  • the drive device comprises means for controlling the supply of the motor means 20 comprising means for detecting the position of the leaf 12, for example a photoelectric position sensor of the electromagnetic limit switches 38, or a coding wheel mounted on the motor shaft (not shown), of known types, delivering signals to the motor 20 identifying the position of the leaf.
  • the mechanism 32 for operating the lock comprises in a known manner two arms 132 and 232 connected by two conjugation rods 332 and 432.
  • the operating mechanism also in known manner, has only one arm.
  • the landing door lock is conventionally constituted by a latch 34 and by two drive rollers 50 and 52 of the landing door.
  • the arms 132 and 232 of the mechanism 32 are adapted to actuate the latch 34 constituted by a bolt 134, a keeper 234 and a release wheel 334.
  • the actuating means 36 of the mechanism 32 for operating the lock comprises a rotary cam 40 disposed on the leaf 12 and driven by the connecting member 22 and a connecting rod 42 d actuation of an arm, such as 132, of the operating mechanism 32.
  • the connecting rod 42 is articulated on the arm 132 by one of its ends and is connected by its other end to the rotary cam 40.
  • the axis 140 of rotation of the cam 40 is arranged in a plane perpendicular to the plane of the leaf 12.
  • the cam 40 includes a lumen 240 with an evolving centrifugal profile having a substantially spiral shape inside which the end of the rod 42 to which it is connected travels during rotation of the cam.
  • the end of the connecting rod 42 connected to the cam, comprises a support roller 340 to facilitate the movement of the connecting rod in the slot 240.
  • actuating rod 42 is slidably mounted in a holding means 142 in a substantially translational movement in a direction parallel to its longitudinal axis.
  • the actuating means 36 of the operating mechanism 32 include a stop for blocking the cam in rotation when the end of the connecting rod 42 has reached the external end of the running part of the lumen 240.
  • the blocking stop comprises a shoulder 44 formed at the base of the leaf 12 on the path of the arm 132 and on which it abuts at the end of the stroke.
  • the blocking stop is provided on the external end of the current part of the lumen 240.
  • actuating means 36 of the operating mechanism comprise a brake 46 disposed on the leaf 12 near the connecting member 22 but offset from the latter when the leaf 12 is in a closed position.
  • This brake 46 consists for example of a fixed element in rotation with an external surface complementary to that of the member 22, or of any device of known type adapted to prevent rotation of the cam 40.
  • a belt tensioner 48 is disposed between one of the drive rollers, such as 30, and the frame of the elevator car.
  • the branches of the operating mechanism 32 are in a close reciprocal position, and are therefore distant from the unlocking wheel 334.
  • the bolt 134 is then engaged with the keeper 234 in order to lock the lock 34.
  • the motor 20 When the cabin is stopped on a storey level, the motor 20 is activated, which causes the rotation of the connecting member 22 in the direction of opening of the leaf 12, as shown by the arrows carried by the connecting member in FIG. 3.
  • the rotary cam 40 is then driven in rotation and the end of the connecting rod 42, connected to the cam, is moved in the light with a spiral profile 240 which causes the displacement in translation of this connecting rod 42.
  • the arm 132 articulated on the connecting rod, is then moved until it comes to the end of the race in abutment against the shoulder 44.
  • the connecting rods 332 and 432 print a lateral movement of this arm which actuates the unlocking wheel 334.
  • the bolt 134 is therefore released from the keeper 234, which then causes the unlocking of the lock 34 .
  • the rotation of the member 22 then causes the leaf 12 to move in the direction of opening.
  • the complete opening of the landing doors is carried out, if necessary, at the same time as the complete opening of the cabin door thanks to the presence of the drive rollers 50 and 52.
  • the position sensor 38 When the position sensor 38 has detected that the leaf 12 is in an open position, as shown in FIG. 3, it sends a signal intended to cut the power supply to the electric motor 20.
  • the arms 132 and 232 of the operating mechanism 32 are actuated and arrive in their close position, as shown in FIG. 5, in which the leaf 12 is again locked in the closed position.
  • the elevator car can then depart to another landing.
  • the opening of the leaf is therefore carried out in two distinct phases which consist on the one hand in blocking the lock during a first part of the travel of the connecting member 22, and on the other hand carrying out the movement of the leaf during a second part of the travel of this connecting member.
  • the leaf is closed in two distinct phases which consist in carrying out the movement of the leaf during a first part of the travel of the connecting member 22, and on the other hand in blocking the latch 34 during a second part of the stroke of the member 22.
  • the drive device according to the invention therefore makes it possible to actuate the operating mechanism 32 of the latch independently of the movements of the leaf 12, which makes it possible to eliminate the synchronization problems encountered in the devices of the prior art.
  • the output shaft of the drive means can be directly connected to the connecting member without providing a means of reducing the speed of rotation and the drive rollers of the connecting member can be directly fixed to the frame of the elevator car without using a tensioner.
