Definitions

  • the present invention relates to an improved device which makes it possible to analyze the pressures exerted on the alarm button of an elevator, or of a hoist, or any other equivalent installation, and to decide whether the call is to be answered. in consideration or if this call results from malice or inattention of the user.
  • It also relates to a device of the aforementioned type which can be coupled to a control system which automatically checks the proper functioning of the elevator.
  • All elevators currently have an alarm system capable of being activated by the user in the event of an operating anomaly. In addition, they are all fitted with safety circuits enabling them to be put out of service in the event of a malfunction.
  • Alarm systems are generally limited to a simple doorbell (or siren, lamp) placed in the elevator shaft or on the landing, said alarm being possibly echoed in a central room, for example at the caretaker of the building. This device is powered by batteries.
  • the device according to the invention can be adapted to any type of existing elevator, regardless of their operating principle, electric or hydraulic, of all generations, of all brands, without intervention on the circuits of security of existing installations.
  • said a-, teardrop control device is associated with an assembly also making it possible to control the proper functioning of the elevator control members.
  • the means for controlling this correct operation are consisting on the one hand, by a sensor placed opposite a movable member of the elevator (traction sheave, deflection pulley, regulator pulley ...), this sensor can be a photoelectric cell, a magnetic detector, or a contact, said sensor being associated with means for automatically controlling the start of the elevator, which can be actuated after a predetermined time, these means making it possible to trigger two calls, at two different levels so as to generate the machine rotation and device reset. It also includes basic means for transmitting information signaling an operating anomaly in the elevator.
  • the alarm discriminator is arranged between the button (1) located in the cabin and the member (2) of the actual alarm transmitter making it possible to transmit the information, for example to a service provider ensuring permanent monitoring for a plurality of devices.
  • This alarm set essentially comprises a holding relay (3), timing means (4-5) and a discriminator proper (6).
  • a monitoring system making it possible to verify the correct operation of the elevator is preferably combined with the alarm assembly illustrated in FIG. 1.
  • Such a system has a structure of the type illustrated in FIG. 2.
  • This system of monitoring essentially comprises a device (7) for detecting the rotation of the machine (8), placed opposite a movable member of said machine.
  • a device is constituted by a sensor (photoelectric cell, magnetic detector, dry contact, etc.) placed opposite, for example, the traction sheave or the deflection pulley that the elevator (8) comprises.
  • This set consists essentially of a timer (9) associated with a reset clutch system (10).
  • the timer (9) controls two successive calls (11-12) on two different stages (13-14), calls which must cause the machine to rotate and the device to be reset.
  • the circuit connected to the alarm allows an analysis to be carried out in three stages.
  • the device After a first press on the button (1), the device is put on standby.
  • the button (1) After a period determined by the timer T2 and before the end of listening determined by the timer Tl, if the button (1) is always or again pressed the alarm is transmitted outside, to a service provider for example, ensuring permanent monitoring of a plurality of devices.
  • the device At the end of the listening period determined by the timer Tl, the device is automatically reset.
  • a main delay is reset to zero each time it is operated by the sensor placed opposite a movable member (traction sheave for example).
  • the timer (9) triggers two successive calls at two different levels.
  • the elevator does not work, it triggers a second call sending the elevator to another floor. If it works, the timer is reset.
  • the invention is not limited to the embodiment described above, but it covers all the variants produced in the same spirit.
  • the alarm discriminator means enabling the reception notice to be displayed in the cabin by the control center, the establishment of a telephone link with the user, emergency lighting in cabin....
  • the device according to the invention is produced from electromagnetic elements, it is obvious that it could be produced by means of electronic elements.
