Definitions

  • the present invention relates to a system for locking and unlocking the door of a toilet module in a transportation vehicle, a process for locking and unlocking said door using said system and a computer program product to carry out said process.
  • Toilet modules for public transportation vehicles are known, such as those in trains, which include a clean water tank, a wastewater tank and flushing systems to discharge the wastewater from the toilet bowl to the wastewater tank.
  • the cited modules have a locking and unlocking system for the door which includes a locking and unlocking mechanism which is activated by a pneumatic actuator linked to an electronic control unit which detects the locked or unlocked position of a lever located inside the module.
  • the same electronic control unit is configured to detect any malfunctioning of the module, be it because the water level in the waste water tank has reached its limit, due to lack of air or power supply or, for example, due to the lack of clean water in the tank.
  • the aforementioned electronic control unit of the module sends an unlocking signal to the pneumatic actuator which activates the unlocking mechanism of the door. Therefore, in the event of a breakdown due to malfunctioning, the user can always leave the module.
  • the existing locking and unlocking systems include a second locking and unlocking mechanism for the door which is activated from outside the module.
  • This mechanism is associated with a square head key which only the train staff can operate.
  • the same staff activates the second locking mechanism using the square head key so that the door remains permanently locked.
  • the objective of the present invention is to solve the aforementioned problems, developing a system for locking and unlocking the door of a toilet module in a public transportation vehicle which has the advantages that will be described below
  • the present invention provides a locking and unlocking system for the door of a toilet module in a public transportation vehicle, which comprises means of locking and unlocking said door when said door is closed, first means of detection of an order to lock or unlock the door coming from the interior of said module, and means of processing and control to supply a signal to said means of locking and unlocking depending on a signal emitted by said first means of detection.
  • the system is characterised by the fact that it includes second means of detection of an order to lock or unlock the door from the exterior of said module, said second means of detection being associated with said means of processing and control to supply a door locking signal to said means of locking, said means of processing and control being configured to allow the unlocking of said door at any time from the interior of said module when said means of processing and control receive an unlocking signal coming from said first means of detection, it being possible to lock said door again to leave the module out of order when the locking signal coming from the exterior of the module persists.
  • the system of the present invention has the advantage that it is possible to lock the door from the exterior by the train staff, and at the same time, unlock said door by a user that may have been left inside. In this way, it is guaranteed that the module remains out of order and locked without the danger of a user being left inside, it being possible to lock the door again when the user leaves when the signal to lock from the exterior persists.
  • the means of locking and unlocking the door are associated with said means of processing and control in that they can receive a signal to lock or unlock the door be it from the exterior (second means of detection) or from the interior (first means of detection).
  • Another advantage of the system stems from the fact that it is possible to carry out an automatic out of order of all of the modules in the vehicle once a journey has been completed, for example, to carry out maintenance operations, given that the means of locking and unlocking the door can be controlled automatically from the exterior without the risk of anybody being left locked inside.
  • said system comprises means of detection of a failure of the module, and wherein said means of processing and control are configured to allow said door to be locked at any time when said means of processing and control receive a failure signal coming from said means of detection, it being possible said door to be unlocked by said means of unlocking upon receiving from said means of processing and control an unlocking signal coming from said first means of detection from the interior of the module, allowing said means of processing and control to lock said door again in order to leave the module out of order when the failure signal persists.
  • the system has the advantage of when an out of order signal is produced due to a failure of the module, for example, owing to a lack of water in the clean water tank, the door locks to leave the module out of order, it being possible to unlock it at any moment from the interior (first means of detection) to allow a user to exit.
  • the module remains locked and out of order, and as a result preventing incorrect use. Furthermore, if there is a user inside, said user can exit and the door will lock again, providing the failure signal continues.
  • the means of locking and unlocking the door are associated with said means of processing and control in that they can receive a signal to lock or unlock the door coming from the interior (first means of detection) and/or from said means that detect the malfunction.
  • said means of locking and unlocking includes a door locking mechanism actuated by a fluid dynamic actuator, and a closed-door electronic sensor associated with said actuator.
  • said locking and unlocking mechanism includes a locking piston actuated by said actuator and a stop element positioned over the door to prevent said door from opening when said stop element comes into contact with said piston.
  • said system is applied on a door that is a sliding door.
  • a door that is a sliding door.
  • any other type of door could be used.
  • said first means of detection of the order to lock or unlock the door coming from the interior of the module include a lever for locking and unlocking situated in the interior of the module, a fluid dynamic actuator to actuate said lever, and at least one electronic sensor associated with said actuator to detect the position of said lever and supply a signal to said means of processing and control.
  • said second means of detection of an order to lock or unlock the door coming from the exterior of said module include a lock provided with a locking and unlocking key, and at least one electronic sensor associated with said key to detect the position of said key and supply a signal to said means of processing and control.
  • said system comprises an indicator of the status of the module, said indicator being associated with said means of processing and control to supply an informative signal on the status of the module according to a signal emitted by said first or second means of detection of the order to lock or unlock the door, or according to a signal emitted by said means of detection of a failure of the module.
  • the system can provide information at any moment on the status of the module coming from the exterior, from the interior or from the operating control system of the module itself.
  • said indicator of the status of the module includes at least one fluid dynamic actuator associated with said informative signal in order to show said informative signal according to the signal emitted by said means of detection of the order to lock or unlock the door or according to said means of detection of a failure of the module.
  • said indicator of the status of the module includes at least three pictograms to provide tactile information of at least three states of the module (for example, out of order, occupied and free).
  • said door is an automatic door and said system comprises a push button to open and close said door automatically from the interior or exterior of the module, said button being associated with said means of processing and control to supply a signal to unlock said door automatically to said means of locking and unlocking said door, such that said door can be at the same time unlocked and open.
  • This embodiment is useful for people with disabilities and has an anti-panic function.

  • This embodiment includes means of processing and control that are configured by an electric processing and control unit and a pneumatic processing and control unit, also called herein automaton of pneumatic logical functions.
  • either one or other unit is determined by the operating conditions of the module 2. Such that, whenever the module 2 has power supply, the system will be governed by the electronic processing and control unit, while the system will be governed by the pneumatic automaton, only in the event that there is no power supply.
  • both electric sensors and pneumatic sensors have been envisaged to detect the actions which operate in the system.
  • the toilet module 2 includes a sliding door 1 with an upper guide 3 that has means of locking and unlocking the door 1.
